This includes production, security, + authentication, release/deployment, workflows, dependencies, firmware, + hardware, networking, native plugins, HomeKit pairing, and voice protocols. +- Low-risk model output is a closed transform DSL: bounded scalar test vectors + and 1-8 allowlisted operations (`center`, `normalize-peak`, `absolute`, + `square`, `difference`, `moving-average`, or `clip`). Local trusted templates + emit exactly five `.md`, `.json`, and `.mjs` files below + `examples/research-sota/nightly//`.

Do NOT grant +# the OIDC id-token write permission before that registration exists, or +# publishing fails with "no trusted publisher configured" — a silent +# regression the `Verify fix markers` guard `RuView#786-pypi-token-auth` +# exists to catch (it forbids that permission string in this file). When +# the owner confirms both entries are live, do the OIDC switch as a +# dedicated follow-up commit (drop `password:`, add the OIDC id-token +# permission + `environment: pypi`) so there is no capability gap between. +# +# Production publishing fails closed until the ADR-117 §11.3 v2 witness +# hash exists.

Ships: (1) a stepped-frequency, multi-position complex forward measurement simulator (`y_{m,k} = Σ σ_j/R² · exp(-i·4π·f·R/c) + noise`, deterministic ChaCha20 seeding); (2) delay-and-sum backprojection reconstruction onto a 3D voxel grid, rayon-parallelized over voxels; (3) threshold + local-maximum point-cloud extraction; (4) closed-form range/cross-range resolution and antenna-pose coherence-budget formulas (`ΔR=c/2B`, `δ_CR≈λR/2L`, `Δp≤λ/8`) checked against the reconstruction's *actual* behavior in `tests/physics_validation.rs` rather than merely documented — forward-simulating two targets at controlled separations and proving they resolve or merge exactly where the formulas predict, and that reconstructed focus at a known target degrades as injected antenna-pose error grows. Every number is SYNTHETIC/L0 (ADR-282) — no real wideband RF hardware backs this crate; see the crate README and `docs/tutorials/coherent-rf-tomography-backprojection.md` for the full honesty boundary and a worked walkthrough. `focus_at_point` exploits the evenly-spaced-by-construction frequency sweep (an arithmetic progression in per-term phase) to evaluate each pose's phasor once and advance it by a fixed complex-multiply step per frequency instead of one `sin`/`cos` pair per frequency — **MEASURED ~4.4-4.5x faster** (criterion regression detection, p < 0.001) than the first-shipped direct-computation version, proven equivalent (not just faster) to an independently reimplemented reference across four sweep sizes and on-/off-target points. 25 tests (22 unit + 3 integration), 0 failed, clippy-clean; MEASURED backprojection throughput ~1.7-2.3M voxels/sec (criterion, 21 poses × 32 freq steps). +- **HOMECORE platform runtime completion — secure native/Wasmtime plugins, authenticated HAP IP, expanded Home Assistant APIs, durable restoration/migration, and voice protocols.** `homecore-server` now owns deterministic compiled-in native plugin registration plus explicitly configured, path-bounded, Ed25519 publisher-verified Wasm packages executed through Wasmtime with setup/state-change/teardown lifecycle; arbitrary native dynamic libraries remain intentionally unsupported. The optional HAP server implements persisted accessory identity and controller records, SRP-6a Pair-Setup M1–M6, X25519/Ed25519 Pair-Verify M1–M4, HKDF-SHA512/ChaCha20-Poly1305 record framing, authenticated/admin endpoint gates, replay/tamper closure, live entity synchronization, and paired-state `_hap._tcp` mDNS updates (45 focused tests; external Apple certification is not claimed). Startup restores device/entity registries and deterministic latest recorder states before plugins, and migration now atomically preserves forward-compatible device/config-entry fields. The HA-compatible surface adds events, templates, config checks, components, registries, history/logbook with SQL-enforced global response bounds, calendar/camera provider routes, and modern WebSocket negotiation while retaining a machine-readable limitations matrix for integration-specific behavior. Assist adds bounded PCM16, async STT/TTS contracts, an end-to-end speech pipeline, and an authenticated satellite session protocol; real deployments still provide the speech engines. +- **`ruview-unified` increment 3 — Gaussian update-loop completion, separable delay-Doppler, and property-tested boundary hardening.** (1) `GaussianMap::merge_overlapping` (ADR-275 step 5: mutual-Mahalanobis + semantic-compatibility dedup catching drift the insert-time gate misses) and lifetime-aware decay (`τ_eff = τ·(1+ln(1+lifetime/τ))` — confirmed structures outlive transients at equal nominal τ). (2) `delay_doppler_map` reimplemented separably (`O(B²S+S²B)`), proven equivalent to the direct reference to <1e-10 and **measured 8.3× faster** (520 µs vs 4.34 ms at 56×8). (3) `tests/security_boundaries.rs` — 8 `proptest` properties over the boundary surfaces (arbitrary values incl. NaN/±inf via `f64::from_bits`) that found and fixed three input-controlled defects: a BLE-CS phase-unwrap infinite loop on non-finite phases and an ~1e299-iteration loop on finite-huge phases (now O(1) modular unwrap + plausibility bound), and a subnormal Gaussian scale overflowing `1/σ²` to NaN density (now physical σ/occupancy bounds). (4) New criterion benches for all increment-2 hot paths (`to_canonical` 38 µs, `ble_cs_range` 481 ns, AoI planner 647 ns/200 regions, coherent fusion 1.5 µs/32 members, factorized pose 521 ns). ruview-unified now 98 tests (87 lib + 3 acceptance + 8 security), 0 failed, clippy-clean. +- **`ruview-unified` increment 2 — native frame contract + programmable perception (ADR-279..282).** (1) `RfFrameV2` becomes the authoritative RF record: native complex IQ with explicit validity masks, declared `PhaseState`, TX/RX poses + antenna geometry in one building frame, calibration/quality state, and a provenance rule enforced at construction — `Synthetic ⇒ L0Simulation` and `Measured ⇒ ≥ L1CapturedReplay` can never alias (the public L0–L5 evidence ladder is now a type); the 56-bin canonical tensor is demoted to a derived compatibility view (`to_canonical`, mask-aware gap-filling through the same normalization path as every adapter; native samples proven byte-untouched). (2) Active sensing control plane (`control.rs`): ETSI-ISAC-vocabulary `SensingTask` admission (raw export always refused; identity requires consent), `SensingAction`/`InformationGoal`, an age-of-information `ActiveSensingPlanner` (priority = uncertainty × change rate × criticality ÷ cost; **measured 95% sensing-traffic reduction** vs uniform refresh on a 20-region scenario), fail-closed `CoherentSensorGroup` fusion gates (time/phase/geometry bounds; five denial paths tested), policy-authorized RIS/movable-antenna actuation receipts, and purpose-scoped `TaskSufficientRepresentation` leakage validation. (3) New modality surfaces: BLE Channel Sounding adapter + `ble_cs_range` treating phase-slope and RTT as **separate cross-validated evidence** (exact distance recovery on synthetic tones; relay-style divergence flagged, never averaged), delay-Doppler-native `FieldAxis` + `delay_doppler_map` (unit-peak tone test), IEEE P3162 synthetic-aperture import profile. (4) RePos-factorized pose head (relative skeleton on the content representation, root on the geometry-conditioned one, calibrated per-joint uncertainties): held-out-room MPJPE 0.0003 m vs 0.2534 m for the monolithic baseline in the room-shortcut leakage experiment; ≤2% structured-adapter budget (740 params). (5) Age gate input now `log(1+age_ms)` per the age-aware-CSI recipe (gradient check re-proven); Gaussian primitives gained `first_seen_ns`/`doppler_variance`/bounded `source_receipts` lineage; `PartitionKey` gained a `session` dimension and `SplitManifest` certifies disjointness across all seven dimensions. 87 tests, 0 failed; crate clippy-clean. Docker images unaffected (no shipped binary consumes the crate yet); Python proof re-verified PASS. +- **`ruview-unified` — unified RF spatial world model, P1 (ADR-273..278).** New v2 workspace leaf crate implementing the five-pillar architecture: (1) canonical `RfTensor` (`links × 56 bins × 8 snapshots`, complex, validated at the boundary) plus a fail-closed hardware adapter registry with reference adapters for 802.11 CSI (consumes `wifi-densepose-core::CsiFrame`), FMCW radar cubes (fast-time DFT), UWB CIR, and 5G SRS (comb de-interleave); (2) a universal RF foundation encoder — window-median + CFO-aligned tokenizer, masked-reconstruction pretraining with a hand-derived backward pass verified against central finite differences (174 params sampled, max rel err 1.31e-5), the ADR-273 fusion contract `z = Enc(CSI) ⊙ σ(AgeEnc) + GeomEnc(pose)`, and ≤1% task adapters (presence 129 / activity 268 / localization 387 / anomaly 2 vs a 40,856-param backbone); (3) an RF-aware Gaussian spatial memory — anisotropic primitives with per-band×angle reflectivity, confidence-weighted fusion, exponential decay, spatial-hash + semantic queries, closed-form (erf) Beer–Lambert channel-gain queries that degrade to exact Friis on an empty map, inverse gain updates that learn an unseen 6 dB obstruction to <0.5 dB in 20 link observations, and a JITOMA-style task-gated scene graph; (4) a physics-guided synthetic RF world generator — Allen–Berkley image method (order ≤2), complex-permittivity Fresnel materials, bistatic person scattering with *emergent* Doppler (proven against the analytic phase rate), seeded ChaCha20 domain randomization of physics + hardware nuisances (gain/CFO/phase noise/packet loss/interference); (5) an edge sensing control plane — 802.11bf/ETSI-ISAC-aligned purposes and zones, fail-closed authorization, a double-gated identity purpose, retention bounds, and a `BoundedEvent`-only trust boundary that makes raw RF export unrepresentable. Anti-leakage evaluation (`StrictSplit` by room/day/person/chipset/firmware/layout with an independent disjointness verifier, ECE, selective risk, degradation) plus an end-to-end acceptance pipeline: presence F1 1.00 on held-out rooms *and* held-out chipset, degradation 0.0, ECE 0.012, p95 tokenize+encode 2.0 ms debug / 105 µs release — **all SYNTHETIC** (honest labeling propagates from `RfModality::Synthetic` through `Provenance.synthetic`). Criterion benches with an optimization pass: segment-corridor candidate search took `channel_gain` from 139 µs → 27 µs (O(1) in map size; hash/linear crossover at ~4k Gaussians reported honestly), `observe_link` 305 µs → 74 µs, precomputed DFT twiddles 4.9×. 66 unit + 3 acceptance tests, 0 failed. + +### Changed +- **crates.io release batch — 10 of the 12 documented crates republished at their next patch version.** `wifi-densepose-core` 0.3.2, `-vitals` 0.3.2, `-wifiscan` 0.3.2, `-hardware` 0.3.2 (picks up the ADR-273..282 review-fix commit's clippy fixes), `-signal` 0.3.6, `-nn` 0.3.2, `-ruvector` 0.3.3, `-train` 0.3.3, `-mat` 0.3.2, `-wasm` 0.3.1 — all published and verified live on crates.io. **`wifi-densepose-sensing-server` and `wifi-densepose-cli` were bumped locally (0.3.5, 0.3.2) but NOT published**: both now path-depend on `ruview-auth`, which is deliberately `publish = false` and not on crates.io — `cargo publish` correctly refuses to publish a crate with an unversioned/unpublishable path dependency. This is a pre-existing gap (the dependency predates this batch); resolving it is a deliberate call for whoever owns whether `ruview-auth` becomes public, not something to route around silently. +- **`wifi-densepose` promoted to `2.0.0` stable; `ruview` `2.0.0` prepared for its first stable publish (ADR-184 P2).** Dropped the `a1` alpha suffix on both sibling packages (`python/pyproject.toml`, `python/ruview-meta/pyproject.toml`) and flipped their trove classifier `Development Status :: 3 - Alpha` → `5 - Production/Stable`; the `ruview` meta-package's `wifi-densepose==2.0.0a1` dependency pins (base + `[client]`) were repointed to `==2.0.0`. **Version-metadata prep only — nothing is published by this change**: the actual PyPI upload remains gated on the ADR-117 v2 witness hash. Justified as "stable": the default (no-extras) wheel builds at 279 KB (`maturin build --release --strip`) and the base non-SOTA suite is green — `pytest python/tests/` (excluding the `[aether]`/`[meridian]`/`[mat]` extra modules) = **185 passed, 0 failed** (smoke / keypoint / pose / vitals / bfld / security / WS+MQTT client). +- **CI (ADR-184): `pip-release.yml` keeps token-based PyPI authentication until Trusted Publishing is registered.** An OIDC migration was attempted in `cc153e8b5` and reverted in `82d5c7339` so releases would not enter a half-configured state. Production currently uses `PYPI_API_TOKEN`; TestPyPI uses its independent `TESTPYPI_API_TOKEN`. The workflow now builds and publishes `wifi-densepose` and `ruview` together, verifies their versions and dependency pin match, and fails closed before production upload when `expected_features_v2.sha256` is absent. +- **`@ruvnet/rvagent` startup optimization — stdio time-to-first-response ~242 ms → ~189 ms (−22%; MEASURED, median of repeated `initialize` round-trips against `dist/index.js`, this container, reproduce with a piped-stdin timer).** Two changes: (1) `./http-transport.js` is now imported **lazily** inside the `RVAGENT_HTTP_PORT` branch — it chain-loads the MCP SDK's `streamableHttp` module (~48 ms MEASURED via per-module `import()` timing), which the default stdio path never uses; (2) the advertised JSON Schemas generated from the Zod sources are memoized per tool instead of re-walking the Zod tree on every `tools/list` (matters under the session-per-server HTTP model where each session lists tools). No behavior change: 99/99 jest tests, HTTP session flow re-smoke-tested through the lazy path. The `@ruvnet/ruview` harness CLI was profiled too and left alone — 50 ms vs the ~29 ms bare `node -e ''` floor on the same box (MEASURED), i.e. already near the interpreter floor with zero dependencies. + +### Deprecated +- **`archive/v1` (the original pure-Python implementation) formally deprecated (ADR-187)** — commits `1fb5397dd`, `b1417fb6e`; refs #509, #1125. Added `archive/v1/DEPRECATED.md` (a loud tombstone) and a `> ⚠️ DEPRECATED` notice atop `archive/v1/README.md`, both pointing at the maintained `v2/` workspace and the `wifi-densepose 2.x` / `ruview` pip wheel (ADR-117). Records the honest fact behind #509: `archive/v1`'s `DensePoseHead` is **architecture-only** — random `kaiming_normal_` init with **zero committed checkpoints** under `archive/v1/` (MEASURED by Glob over `**/*.{pth,onnx,safetensors,pt,ckpt,bin}`). The ADR-028 deterministic proof `archive/v1/data/proof/verify.py` stays live and is explicitly out of scope. The same effort added a **"Model weights: what's real, what's not" three-tier table** to `README.md` + `docs/user-guide.md`, separating real-and-validated checkpoints (presence 82.3% held-out temporal-triplet, MM-Fi pose 82.69% torso-PCK@20, `count_v1`) from the real-but-weak on-device `pose_v1` (PCK@20 = 3.0%, runtime `confidence=0` stub, below the ADR-079 ≥35% target) from the architecture-only `archive/v1` head — and caveated every live single-ESP32 17-keypoint advertisement accordingly. Docs/labeling only; no code or model behavior changed. + +### Fixed +- **`docs/huggingface/MODEL_CARD.md` had drifted from the model card actually published on the Hub (issue #1481).** Every filename in its "Files in this repo" table (`pretrained-encoder.onnx`, `pretrained-heads.onnx`, `pretrained.rvf`, `room-profiles.json`) pointed at files never uploaded to `ruvnet/wifi-densepose-pretrained` — only `config.json` existed. Replaced the in-repo card with the content actually live on the Hub (`model.safetensors`, `model-q{2,4,8}.bin`, `node-{1,2}.json`, `presence-head.json`, `csi-embed-v2.*`, honest v1→v2 retraction of the single-class "100%" presence claim) and added a "Using with the Rust sensing server (RVF conversion)" section documenting the `--convert-model`/`--convert-out` and `--model` auto-convert paths that neither card previously mentioned. +- **`--convert-model` failed on the published `model.safetensors`: NUL-padded safetensors header rejected by strict JSON parse (issue #1480, #894 follow-up).** The reference safetensors format pads its JSON header to an 8-byte boundary with trailing NUL bytes; `safetensors_to_rvf` (`wifi-densepose-sensing-server/src/model_format.rs`) fed the full declared-length header slice straight to `serde_json::from_slice`, which rejects the padding as "trailing characters." Since the only published full-precision weight file exercises this padding, `--convert-model` could not convert it at all. Fixed by trimming trailing NUL/whitespace bytes before parsing. Pinned by `safetensors_nul_padded_header_converts` (a header padded to the 8-byte boundary, matching the real HF file, converts and round-trips its weights through `ProgressiveLoader`). +- **In-server training reconnected — "Start Training" no longer silently no-ops; `/ws/train/progress` streams real progress (ADR-186, issue #1233).** The dashboard's Start Training button POSTed a config, got `success:true`, and nothing happened: `/api/v1/train/start` was a stub that flipped a status string and logged one line, and `/ws/train/progress` 404'd. The full pure-Rust trainer in `training_api.rs` (loads recorded CSI, gradient-descent, exports a `.rvf`) already existed but was **orphaned** — never declared as a module (no `mod training_api;`), so it wasn't compiled at all. Fix (`wifi-densepose-sensing-server`): declared the module, reconciled `AppStateInner` (replaced the `training_status`/`training_config` stub fields with a shared `TrainingState` status handle + cooperative cancel flag + a `training_progress_tx` broadcast), deleted the stub handlers, and merged the real `training_api::routes()` (so `/api/v1/train/{start,stop,status,pretrain,lora}` and `/ws/train/progress` resolve under the existing `/api/v1/*` bearer gate). The training core was decoupled from the ~60-field server state so it is unit-testable. **P5 honesty guarantee:** with `RUVIEW_DISABLE_SERVER_TRAINING` set, start returns a structured `{enabled:false, cli:"wifi-densepose train-room"}` HTTP 409 — never a silent success — and the dashboard disables the Start buttons with a CLI tooltip (enablement is surfaced on `/api/v1/train/status`). Pinned by 8 new tests incl. a **live-socket** test that completes a genuine 101 WebSocket handshake and receives a real progress frame after a POST start, a full POST→poll-status→`.rvf`-exists round-trip, a path-traversal rejection, cancellation, and the disabled-409 path. `cargo test -p wifi-densepose-sensing-server -p wifi-densepose-train --no-default-features` — 0 failed. +- **FastAPI health/metrics endpoints event-loop starvation.** Calling `psutil.cpu_percent(interval=1)` blocked the single-threaded async event loop for 1.0 second on every health check or metrics collection tick, stalling all incoming requests and WebSocket operations. Fixed by changing `cpu_percent` to use non-blocking `interval=None` and offloading all blocking OS metrics gathering to background thread pools via `asyncio.to_thread`. Verified event loop responsiveness via concurrency regression tests. +- **EngineBridge now honors `WDP_GUARD_INTERVAL_US`/`WDP_SOFT_GUARD_US`/`WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US`** (#1309, PR #1312, @erichkusuki). The governed trust path previously built its multistatic fuser from a hardcoded `MultistaticConfig::default()` (60 ms guard), so multi-node deployments with WiFi/ESP-NOW time sync (10–150 ms drift) failed every governed cycle regardless of configuration — while the startup log claimed the override took effect. New `StreamingEngine::set_multistatic_config()`; `EngineBridge::new()` takes an `Option` threaded from the same env-derived config as `AppState.multistatic_fuser`. Hardware-verified on a live 2-node ESP32-S3 setup (90 s window, 0 fusion errors; previously every cycle failed). +- **`/api/v1/stream/pose` WebSocket reachable with `RUVIEW_API_TOKEN` set + dashboard bearer-token field** (#1310, PR #1313, @erichkusuki). Browsers cannot attach an `Authorization` header to a WS upgrade, so the Live Demo pose stream always failed when auth was on; the path is now on a narrow exact-match exemption list (mirrors `/ws/sensing`), with a regression test pinning that the exemption doesn't leak to other `/api/v1/*` paths. The QuickSettings panel gains an "API Access" field storing the bearer token in `localStorage`; the token is applied at `api.service.js` module load so the very first request carries it. +- **Display-less DevKitC-1 boards: `sdkconfig.defaults.devkitc` build overlay** (#1308, PR #1311, @erichkusuki). The ADR-045 runtime display probe false-positives on stock ESP32-S3-DevKitC-1 (floating QSPI pins), which silently skipped the RuView#893 MGMT+DATA CSI upgrade and collapsed CSI yield to 0 pps. The overlay compiles display support out (`has_display` constant-false). Also fixes stale `espressif/idf:v5.2` README references to v5.4 (source requires `esp_driver_uart`, IDF ≥5.3). Hardware-verified on 2× DevKitC-1-N16R8 (0 → 40–45 pps). +- **ADR-263/264/265 implemented — the RuView npm surface fixed end-to-end (`@ruvnet/ruview@0.2.0`, `@ruvnet/rvagent@0.2.0`, `@ruv/ruview-cli`).** Harness (ADR-263 O1–O9): `claim-check` now **fails closed** on empty input (CLI exit 2 + `empty_text` tool error); the MCP stdio server dispatches `tools/call` asynchronously over promise-based `spawn` — `ping` answers while a long `verify`/`calibrate` runs (pinned by a new e2e test that runs a 3 s fake proof and asserts sub-second ping); the two `optionalDependencies` are gone so a cold `npx` installs exactly 1 package (MEASURED: was 4 packages / 620 kB / 71 files, `npm i` in a clean prefix); child output is captured as bounded rolling tails (no more 1 MiB `maxBuffer` kills); `node_monitor` passes the port via `sys.argv` instead of splicing it into `python -c` source; the MCP `serverInfo.version` reads package.json; `.claude/skills/*/SKILL.md` are generated from `skills/*.md` by a `prepack` sync script (byte-equality pinned by test); `which()` is a memoized dep-free PATH scan; tools are underscore-canonical (`ruview_claim_check`, …) with the dotted names accepted as call-time aliases, plus `resources/list`/`prompts/list` stubs; the guardrail's `METRIC_TERMS` matching is precision-fixed (word-boundary `map`/`f1`/`auc`/`iou`, code-span + label scrubbing, quantitative-claims-only) — ADR-263/264/265 and both package READMEs now PASS `claim-check` while real untagged claims still flag. 30/30 tests (MEASURED, `node --test`). rvagent (ADR-264 O1–O9): `exports` fixed (types-first, the never-built `dist/index.cjs` `require` target removed — verified broken in the published 0.1.0 tarball); tarball is map-free (127,704 B unpacked / 46 files / 0 maps — MEASURED, `npm pack --dry-run`, down from 188 kB with 44 maps); the Streamable HTTP transport is **actually wired** behind `RVAGENT_HTTP_PORT` with one transport + one MCP server per session (`mcp-session-id` routing), a 1 MiB body cap (413), and a port-aware localhost origin gate — the "dual-transport" description is now true; tools renamed to underscore-canonical with dotted router aliases; ONE Zod validation gate per call with the advertised JSON Schema generated from the same Zod source (`zod-to-json-schema`); `train_count` closes its log fds (was leaking 2/job) and persists job records to `/.json` so `job_status` survives restarts, with bounded log-tail reads; `detectCogBinary` actually probes its candidate paths; version reads package.json; `@types/express` dropped, `@types/jest` aligned to jest 29; README rewritten to match reality (no phantom `stdio`/`http`/`policy grant` subcommands; unimplemented ADR-124 catalog tools labeled roadmap). 99/99 jest tests (MEASURED); stdio handshake + HTTP session flow + 403/400/404/413 gates smoke-tested live. CLI: bin renamed `ruview-cli` (the `ruview` bin belongs to `@ruvnet/ruview`, ADR-265 D4), version single-sourced. Distribution (ADR-265 D1–D4): new `npm-packages.yml` (3-package × Node 20/22 matrix: tests, version-literal grep gate, pack-content/size gate, tarball-install smoke test incl. the fail-closed claim-check and an ESM-import probe that would have caught the broken `require` export, README claim-check) and `ruview-npm-release.yml` (publish from CI only, `npm publish --provenance`); `ci.yml` NODE_VERSION 18→20. +- **Empty-room field-model calibration collected nothing on real HT40 nodes — raw 128-wide frames rejected by the 56-tone model (follow-up to the deadlock fix below).** Once the status-gate deadlock was fixed, `maybe_feed_calibration` reached `feed_calibration`, but a real ESP32 HT40 node streams 128-wide amplitude vectors while the single-link `FieldModel` is the canonical 56-tone grid — so `LinkStats::update` returned `DimensionMismatch`, `feed_calibration` bubbled the error, and `maybe_feed_calibration` swallowed it at `debug` level. Net effect: `frame_count` stayed pinned at 0 on live hardware even though presence/motion/vitals (which read the global history) worked fine. Fixed by resampling each frame onto the model's canonical 56-tone grid via `HardwareNormalizer::resample_to_canonical` before feeding — the same length-only canonicalization the multistatic fusion path uses (#1170). Pinned by `field_bridge::maybe_feed_calibration_resamples_wide_frames_and_accumulates` (128-wide frame → Collecting + count 1; fails on old code). Verified live on the ESP32-S3 deployment. +- **Empty-room field-model calibration could never start — `/api/v1/calibration/*` was a dead endpoint (frame count pinned at 0).** `POST /calibration/start` creates the `FieldModel` in `Uncalibrated`, but the per-frame server feed `field_bridge::maybe_feed_calibration` only fed observations while the model was **already** `Collecting` — and the *only* thing that sets `Collecting` is `feed_calibration` itself (on its first fed frame). The two gates deadlocked: nothing ever fed the first frame, so `calibration_frame_count` stayed 0, `status` never left `Uncalibrated`, and the SVD room eigenstructure (eigenvalue-based person counting / localization) could never calibrate — observed live as `{"status":"Uncalibrated","frame_count":0}` never advancing on a streaming ESP32 node. Fixed the guard to feed while `Uncalibrated | Collecting` so the first frame flips the model to `Collecting` and the count advances. Also made `calibration_stop` return a structured `{success:false, frame_count, frames_needed}` (with a new `FieldModel::min_calibration_frames()` accessor) instead of an opaque 500 when finalized before enough empty-room frames accumulate. Pinned by `field_bridge::maybe_feed_calibration_advances_uncalibrated_to_collecting` (asserts `Uncalibrated → Collecting` + count 0 → 1 → 2; fails on old code). Presence/motion/vitals were unaffected — they use the separate auto rolling baseline, not the field model. +- **Multistatic fusion never ran on a mixed-mode ESP32 mesh — live bridge fed raw, un-canonicalized per-node CSI to the fuser (#1170).** `node_frame_from_state` (`multistatic_bridge.rs`) wrapped each node's **raw** amplitude vector (HT20 ≈ 64 bins, HT40 ≈ 128/192) into a struct *named* `CanonicalCsiFrame` without ever resampling, so `MultistaticFuser::fuse` tripped `DimensionMismatch` on every cycle, silently fell back to per-node sum/dedup, and spun `total_engine_errors` unbounded. Added `HardwareNormalizer::resample_to_canonical` (resample-only, **no z-score** — preserves the amplitude scale the person-score's `variance/mean²` relies on) and run every node frame through it onto the canonical 56-tone grid before fusion. Heterogeneous meshes now fuse instead of erroring. Pinned by `heterogeneous_node_counts_canonicalize_and_fuse` (mixed 64/192 → fuses), `resample_to_canonical_is_length_only_no_zscore`, and an updated `test_node_frame_conversion`; the pre-existing `engine_bridge::observe_cycle_counts_engine_errors` was retargeted to force a `TimestampMismatch` (its old 56-vs-30 setup now canonicalizes cleanly). `wifi-densepose-signal` 501 / `wifi-densepose-sensing-server` 677 tests, 0 failed. +- **`csi_fps_ema` reported the CSI frame rate 40–840× too high under bursty UDP delivery (#1180).** `update_csi_fps_ema` only rejected deltas `≤ 0` or `≥ 1 s`, so a 36 µs intra-burst arrival delta yielded `1/dt ≈ 27 kHz` straight into the EMA — the metric measured server arrival jitter, not the node's ~40 fps production rate. Added a `MIN_PLAUSIBLE_CSI_DT_SEC = 0.005` floor (derived from the firmware's 50 fps `CSI_MIN_SEND_INTERVAL_US` ceiling, ×4 slack) and made `observe_csi_frame_arrival` keep its anchor across sub-floor bursts so the next genuine inter-frame gap measures true cadence. Pinned by `subms_burst_delta_rejected`, `burst_interleaved_with_nominal_stays_in_band`, and `observe_csi_frame_arrival_ignores_subms_bursts`. +- **`stream_sender` ENOMEM backoff starved low-rate control packets under a weak uplink (#1183, follow-up to #1135/#1159).** The global `s_backoff_until_us` gate (triggered by the 50 Hz CSI flood at weak RSSI) also suppressed the ≤48 B, ≤1 Hz `feature_state` / mesh `HEALTH` / sync packets that contribute negligible buffer pressure, so telemetry failed essentially every cycle. Added `stream_sender_send_priority()` — bypasses the backoff gate, reports ENOMEM quietly, and never extends/resets the global streak — and routed `feature_state`, HEALTH/anomaly (`rv_mesh_send`), and sync packets through it. Also fixed the misleading `"HEALTH sent"` log that printed unconditionally even when `rv_mesh_send` returned `ESP_FAIL` (now prints `sent`/`FAILED` from the actual return). Firmware builds clean (ESP-IDF v5.4). +- **Multistatic fusion guard interval is now operator-configurable — fixes permanent trust demotion with WiFi-synced ESP32 nodes (#1049).** Two independently-clocked ESP32-S3 boards on ESP-NOW sync drift 10–150 ms (typ. ~70 ms) — the 100 ms beacon + WiFi-MAC jitter cannot hold them within the published 60 ms default guard, so the governed-trust cycle permanently demoted to `Restricted`, suppressed all pose output, and spun the error counter to 200k+ with **no escape hatch but a container restart**. Added a **direct `WDP_GUARD_INTERVAL_US` override** (+ optional `WDP_SOFT_GUARD_US`) to `multistatic_guard_config_from_env`, so a deployment can lift the hard guard past its measured spread (e.g. `WDP_GUARD_INTERVAL_US=200000`) without having to know its exact TDM schedule. Precedence is most-specific-wins: a direct override beats the existing `WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US` schedule-derived guard, which beats the 60 ms/20 ms default; the override is applied on top of whichever base is selected, the soft band is always clamped strictly below the hard guard, and a malformed/zero value is ignored (falls back to the base rather than breaking fusion). The effective guard is now logged at startup. Pinned by 6 new tests (`multistatic_guard_config_tests`): direct-override-wins / beats-TDM-derived / soft-clamped-below-hard / lowering-hard-pulls-soft-down / malformed-or-zero-falls-back / default-when-unset. `wifi-densepose-sensing-server` bin tests **449 → 455**, 0 failed; Python proof VERDICT PASS, hash unchanged (off the signal proof path). + +### Security +- **`wifi-densepose-occworld-candle` — beyond-SOTA security + correctness review (Milestone #9, crate 4/4).** (1) **HIGH (MEASURED) — checkpoint-load crash on any int32 tensor** (`model.rs::safetensor_dtype_to_candle`). `safetensors::Dtype::I32` was mapped to `candle_core::DType::I64` and the raw int32 byte buffer (4 bytes/elem) was then handed to `Tensor::from_raw_buffer(.., I64, shape, ..)`. Candle derives `elem_count = data.len() / dtype.size_in_bytes()`, so the I64 path halved the element count while keeping the *original* shape — yielding a tensor whose declared shape claims twice as many elements as its backing storage holds. Reading it **panics** (`range end index 6 out of range for slice of length 3` — slice OOB inside candle-core) on any attacker-supplied or PyTorch-exported checkpoint containing an int32 tensor (common: index/buffer tensors). Fixed by mapping `I32 → DType::I32` (and `I16 → DType::I16`), both first-class candle dtypes. Reproduction recorded on old code; pinned by `tests/checkpoint_loading.rs::int32_tensor_loads_with_consistent_shape_and_values` (panics on old, passes on new) plus F32/I64/corrupt-file control cases. (2) **LOW (MEASURED) — `predict()` lacked frame/batch validation at the input boundary** (`inference.rs`). It validated H/W/D but not the externally-supplied frame count; an `f_in > num_frames*2` over-indexed the temporal positional embedding deep in the transformer and surfaced as a cryptic candle "gather" `InvalidIndex` (returned error, not a panic — candle bounds-checks), and a zero frame/batch dim fed a zero-element tensor into the pipeline. Now rejected at the boundary with a clear `ShapeMismatch`. Pinned by `predict_rejects_zero_frames` / `predict_rejects_too_many_frames` / `predict_accepts_frame_count_at_capacity`. (3) **LOW (MEASURED) — divide-by-zero panic on a degenerate input to the public `VQCodebook::encode`** (`vqvae.rs`): a rank-0 / empty-last-dim tensor made `last == 0` and panicked on `elem_count() / last`. Now fails closed with a clear error. Pinned by `encode_rejects_scalar_without_panicking`. **Dimensions confirmed CLEAN with evidence:** panic surface — zero `unwrap()`/`expect()`/`panic!`/`unreachable!` in production code paths (grep evidence; all error handling via `?`/`map_err`); NaN-state-poisoning — N/A (engine is stateless between `predict` calls, input is `u8` class indices so non-finite input is structurally impossible, no persistent world-model buffer to latch into); unbounded-alloc / shape-data mismatch from malformed weights — defended upstream by `safetensors::validate()` (overflow-checked `nelements*dtype.size()` vs declared byte range, rejected before reaching candle); secrets — none (grep clean, only `token_h`/`token_w` config fields match). `unsafe_code = forbid` in the crate manifest. **Build/validation status (MEASURED on Windows):** crate builds and tests under `cargo test -p wifi-densepose-occworld-candle --no-default-features` — **29/29 pass** (20 unit + 4 checkpoint_loading + 3 predict_honesty + 2 doc) after fixes; `cargo test --workspace --no-default-features` = 0 failed across all crates (lone `wifi-densepose-desktop` `api_integration` failure was a Windows "Access is denied (os error 5)" file-lock flake — re-ran in isolation **21/21 pass**); Python proof VERDICT PASS, hash `f8e76f21…446f7a` unchanged. *Warrants ADR slot 179 (parent to author).* +- **`wifi-densepose-wasm-edge` beyond-SOTA closing review — boundary NaN-state-poisoning guard + clean-with-evidence attestation (ADR-040 edge crate, ~70 modules).** Closing pass of the security campaign over the last untouched sizeable crate. **One real finding fixed (LOW / source-analysis + reproduced):** the two WASM↔host frame boundaries (`lib.rs::on_frame`/`on_timer` and `bin/ghost_hunter.rs::on_frame`) read raw IEEE-754 `f32` from the `csi_get_phase`/`csi_get_amplitude`/`csi_get_variance`/`csi_get_motion_energy` host imports **without any finiteness check** — the entire crate had **zero** `is_finite`/`is_nan` guards, and the in-crate `clamp` helpers propagate NaN (`NaN < lo` and `NaN > hi` are both false). A single non-finite value (firmware DSP bug, uninitialised buffer, or hostile host) latches NaN into the long-lived per-module accumulators (EMA, Welford, phasor sums, anomaly baselines); once latched, every downstream comparison evaluates `false`, so detectors fail **degraded** (stuck gate state, silently-disabled anomaly checks) — silent corruption, not a crash (WASM `panic=abort` is *not* tripped: no indexing/`unwrap` on the poisoned value). Threat model is a **semi-trusted** boundary (the Tier-2 DSP firmware supplies the imports, not direct network/JS), hence LOW severity / defense-in-depth. **Fix:** added `sanitize_host_f32()` (maps non-finite→`0.0`, `core`-only so it holds in `no_std`) applied at every `host_get_*` float read — a single chokepoint covering all ~70 downstream modules, mirroring the existing M-01 negative-`n_subcarriers` boundary clamp. **Pinned by** `boundary_tests::{sanitize_passes_finite_values_through, sanitize_maps_non_finite_to_zero, coherence_monitor_nan_latches_without_sanitize_but_not_with}` — the last asserts on the *current* `CoherenceMonitor` that a raw NaN frame latches the smoothed score (documents the hazard) while the boundary-sanitized path stays finite. **Dimensions attested CLEAN with evidence (source-analysis):** (a) **panic-on-input** — every non-test `unwrap()`/`expect()` is either `#[cfg(test)]` or in the `std`-gated RVF *builder* host tool writing to an in-memory `Vec` (infallible); no `panic!`/`unreachable!`/`todo!`/`get_unchecked` in any hot path. (b) **shape/bounds** — all frame-buffer access is `min()`-clamped (`MAX_SC=32`, `DTW_MAX_LEN`, `LCS_WINDOW`, `PATTERN_LEN`), all index-by-cast sites (`feature_id as usize`, `conclusion_id`, `minute_counter`, `plan_step`) are either compile-time-const-bounded or `if idx <`/`%`-guarded; negative `n_subcarriers` already mapped to 0 (M-01). (c) **memory/leak** — no `move ||` closures, no `mem::forget`/`Box::leak`/`.leak()`; the only `Box::new` is in the `std`-gated `skill_registry` (one-time init, bounded). (d) **secrets** — none (grep clean). **MEASURED build/test evidence:** host `cargo test --features std,medical-experimental` = **672 passed / 0 failed** (was 669 pre-fix; +3 new tests); the real deployment artifacts all build clean on the actual target — `cargo build --target wasm32-unknown-unknown --release` (no_std/panic=abort default lib), `--bin ghost_hunter --no-default-features --features standalone-bin`, and `--features medical-experimental` (toolchain 1.89 per `rust-toolchain.toml`). No ADR slot needed — a single LOW defense-in-depth boundary fix; CHANGELOG attestation suffices. +- **ADR-131 HOMECORE-UI BFF gateway — public-PR review fixes (PR #1082).** (1) **HIGH — path-traversal / confused-deputy SSRF closed in the `/api/cal/*` reverse-proxy** (`homecore-server/src/gateway.rs`). The wildcard proxy path was interpolated straight into the upstream URL while `proxy()` attaches the server-side calibration bearer, so `/api/cal/v1/../../x` (and percent-encoded `..%2f`, `%2e%2e`, leading `/`, backslash, double-encoded `%252e`) could escape the `…/api/` scope **with the privileged token**. Now `validate_proxy_path()` decode-then-checks and rejects absolute/backslash/dot-segment/encoded-traversal paths with a typed **400 BEFORE the URL is built** (applies to GET **and** POST); legit `v1/...` paths still pass. Pinned by `cal_proxy_rejects_traversal_with_400_before_upstream` (fails on old code) + `validate_proxy_path_rejects_traversal_variants`. (2) **CORS + request-tracing now cover the gateway routes.** `/api/homecore/*` and `/api/cal/*` were `.merge()`d **outside** the layers `homecore-api::router()` applies, leaving them with no CORS allowlist and untraced; the audited `build_cors_layer()` (HC-05) + `TraceLayer` are now applied to the whole merged surface in `main.rs`. Pinned by `gateway_routes_are_cors_covered_after_merge` (Vite-dev-origin preflight succeeds on a gateway route). (3) **Fabricated-data honesty (§6 invariant 3):** the gateway no longer injects a hardcoded `anomaly.threshold: 0.5` — it passes through the REAL upstream threshold or emits `null` (withheld); the dashboard renders a not-available `—` instead of `"null%"`/`"null°C"` for null appliance metrics; the COG panel's Hailo-worker pill reflects the real appliance probe instead of a hardcoded `"connected"`; `rooms.js` treats a null anomaly threshold as withheld, not a fake `0.8` default. (4) **Robustness:** a forwarded `hef` that is a string (not an array) no longer throws in the COG panel; the calibration wizard guards `frames/target` against `NaN%`/`Infinity%` and clears its baseline poll timer on Restart / panel teardown (leaked `setTimeout` loop fixed). (5) **Perf:** per-bank RoomState fetches and the appliance service probes now run concurrently (`futures::join_all`; async `tokio::net::TcpStream` + `timeout` replaces the blocking `connect_timeout` that parked a worker per probe); the mock fixture module is now a dynamic `import()` gated on demo mode so production never bundles it. **Note (workspace-wide, not fixed here):** `homecore-server` requests `reqwest`'s `rustls-tls` only, but cargo feature-unification means a sibling crate enabling the default `native-tls` re-introduces OpenSSL into the final binary regardless — a true "no OpenSSL on the appliance" guarantee requires aligning every reqwest-pulling crate on rustls-only. **Note (pre-existing, out of scope):** DEV-mode `allow_any_non_empty()` bearer auth when `HOMECORE_TOKENS` is unset on `0.0.0.0` is unchanged; the loud `warn!` at boot is retained — provision real tokens before network exposure. **Verified:** `cargo test -p homecore-server --no-default-features` = **18/18 pass**, `cargo build -p homecore-server` clean, UI suite (`node tests`) all green, Python proof VERDICT PASS (hash unchanged). +- **`wifi-densepose-desktop` (Tauri v2 desktop app) beyond-SOTA security review (needs ADR slot 178) — one real IPC serial-command-injection fix + one over-broad shell-capability removal, each MEASURED on Windows; remaining IPC/path/secret dimensions confirmed clean with evidence.** Beyond-SOTA review of the Tauri desktop crate (the real attack surface is the webview→Rust IPC boundary + the capability allowlist). The crate **builds + tests on this Windows box** (`cargo check`/`cargo test -p wifi-densepose-desktop --no-default-features` — Tauri 2.10 + GTK-less Windows webview2 path), so both findings are **MEASURED**, not source-analysis. **WDP-DESK-01 (serial command injection via `configure_esp32_wifi`, MODERATE) — FIXED.** The `#[tauri::command] configure_esp32_wifi(port, ssid, password)` handler took `ssid`/`password` straight from the webview and concatenated them into newline-terminated serial commands (`format!("wifi_config {} {}\r\n", ssid, password)`, `set ssid {}\r\n`, …) with **zero validation** before writing them to the ESP32 over the line-oriented serial protocol. A `\r\n` embedded in either field lets a malicious/compromised webview **terminate the command line early and inject an arbitrary follow-up firmware command** (`reboot`, `erase_nvs`, etc.) — a command-injection-into-device-protocol crossing the IPC trust boundary. Ironic note: the crate already shipped `test_wifi_credentials_validation` documenting the WPA2 length bounds, but the handler never enforced them. **Fix:** a new `validate_wifi_credentials(ssid, password)` rejects out-of-range lengths (SSID 1-32, password 8-63 — WPA2 PSK bounds) **and any control character** (`char::is_control()` catches `\r`/`\n`/NUL), called at the top of the handler before any serial write — fail-closed (`Err` → no bytes sent). Pinned fails-on-old / passes-on-new by `test_validate_wifi_credentials_rejects_injection` (`"net\r\nreboot"`, `"net\ninjected"`, `"pass\r\nerase_nvs"`, embedded NUL — all rejected; would splice into the command stream pre-fix), `test_validate_wifi_credentials_rejects_out_of_range`, and `test_validate_wifi_credentials_accepts_valid` (boundary 32-char SSID / 8- and 63-char passwords still accepted). **WDP-DESK-02 (over-broad shell capability, MODERATE) — REMOVED.** `capabilities/default.json` granted the webview `shell:allow-execute` + `shell:allow-open`, but the Rust backend spawns every process via `std::process::Command` directly (espflash/which/sensing-server — which **bypasses** the Tauri allowlist entirely) and the React UI only ever calls `dialog.open` (file picker) — verified by grep: `tauri_plugin_shell` is `init()`-ed but its `Command`/`open` API is **never invoked from Rust or TS**. The two `shell:` permissions were therefore unused privilege: a webview compromise (e.g. XSS in a UI dep) would have gained **arbitrary host command execution** via `shell.execute` with no scope restriction (no `shell` scope object was even defined). **Fix:** removed both `shell:` permissions from the capability (kept `core:default` + the two `dialog:` perms the UI actually uses). MEASURED: the build-regenerated `gen/schemas/capabilities.json` now reads `"permissions":["core:default","dialog:allow-open","dialog:allow-save"]` (shell perms gone), and the crate still builds + all tests pass — confirming nothing depended on the granted shell scope. (Plugin `init()` + the npm dep left in place to keep the blast radius minimal and avoid touching the off-limits generated ACL manifests; with no permission granted the plugin is inert.) **Dimensions confirmed clean (with evidence):** (1) **No directory-traversal / arbitrary-file primitive crossing the boundary** — the path-taking commands (`flash_firmware`/`verify_firmware`/`ota_update`/`wasm_upload`/`provision_*`) pass the webview-supplied path to `std::fs`/`espflash` to **read a firmware/wasm blob the local user themselves selected via the `dialog.open` native picker**; there is no command that *writes* to or *reads back* an arbitrary attacker-named path to the webview — `settings` read/write is confined to `app_data_dir().join("settings.json")` (fixed filename, no user path component), so no traversal sink exists. (2) **No shell-string interpolation** — every subprocess uses `Command::new(prog).args([...])` (argv vector, no shell), so the `port`/`source`/`chip`/`baud` args cannot inject a second command even though they are unvalidated (the `source` value flows only as a single `--source ` argv element). (3) **No SSRF-to-secret** — the `node_ip`-built URLs (`http://{ip}:8032/...`) target the local ESP32 mesh and return only device status; no credential is returned to the webview. (4) **Panic-on-input** — handlers use `.map_err(|e| e.to_string())?` throughout; the one `srv.pid.expect(...)` in `server_status` is guarded by an explicit `is_none()` early-return on the line above (unreachable), and the discovery/provision deserializers bounds-check before every slice index (`pos + len > data.len()` guards, NVS size capped at 4096). (5) **No hardcoded secrets** — `ota_psk` is an `Option` supplied per-call/from settings, never embedded; grep for embedded keys/tokens over `src/` is empty. (6) **Tauri config** — `tauri.conf.json` ships no `"all": true` / `"$HOME/**"` FS or HTTP scope (no `fs`/`http` plugin enabled at all); the window set is a single fixed main window. `cargo test -p wifi-densepose-desktop --no-default-features`: lib **18 → 21 passed** (+3 validator pins), integration **21 → 21**, 0 failed. Workspace otherwise unchanged; Python deterministic proof unchanged (`f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a`, bit-exact — the desktop crate is off the signal proof path). Both findings warrant **ADR slot 178**. +- **`ruview-swarm` beyond-SOTA security + correctness review (ADR-148 drone swarm control plane; needs ADR slot 176) — 4 real fail-open / DoS bugs fixed in the NaN-state-poisoning class, each pinned fails-on-old / passes-on-new; 5 dimensions confirmed clean with evidence.** The shared theme is **IEEE-754 NaN/Inf silently defeating a safety comparison** on data that crosses the untrusted swarm-comm trust boundary (`SwarmOrchestrator::receive_peer_state` / `receive_peer_detection` accept full `DroneState`/`CsiDetection` whose f64/f32 fields deserialize with no finite-check; the integer-encoded MAVLink wire formats in `mavlink_messages.rs` cannot carry NaN, but the serde struct path can). **(1) HIGH — `failsafe::FailSafeMachine::tick` collision-avoidance + battery fail-open** (`failsafe/mod.rs:51,75`). `nearest_neighbor_dist < collision_dist_m` and `battery_pct <= rth_pct` both evaluate `false` for a NaN operand, so a poisoned peer position (→ NaN `nearest_peer_distance` via `Position3D::distance_to`) **silently disabled collision avoidance** and a NaN battery reading kept a drone Nominal — the worst failure for a physical airframe. Fixed to fail CLOSED (`!is_finite() ||` → `EmergencyDiverge` / `ReturnToHome`). MEASURED fails-on-old: `test_nan_neighbor_distance_fails_closed_to_diverge` / `test_nan_battery_fails_closed_to_rth` both returned `Nominal` pre-fix. **(2) MEDIUM — `security::geofence::Geofence::check` NaN-altitude bypass** (`security/geofence.rs:33`). A NaN `z` (altitude) with valid x/y skipped the altitude breach (`NaN < min || NaN > max` = `false`) and returned **`Safe`** through the point-in-polygon path — a silent geofence bypass. Fixed with a leading non-finite-coordinate → `HardBreach` guard. MEASURED fails-on-old: `test_nan_altitude_fails_closed` returned `Safe` pre-fix. **(3) MEDIUM/DoS — `security::antijamming::FhssRadio` `% 0` panic on empty `channels_mhz`** (`security/antijamming.rs:65,71,102`). `FhssConfig` is `Deserialize`; an empty channel list (malformed/hostile config) made `next_hop`/`current_channel_mhz`/`evasive_hop`/`tick` panic with `remainder with a divisor of zero`, crashing the radio task. Fixed with `len == 0` early-returns (benign `0.0` sentinel). MEASURED fails-on-old: `test_empty_channels_does_not_panic` **panicked** (`divisor of zero`) pre-fix. **(4) LOW — `sensing::multiview::MultiViewFusion::fuse` NaN victim-position propagation** (`sensing/multiview.rs:70`). A NaN `victim_position` passed the `is_some()` filter and propagated through the confidence-weighted average into the fused "confirmed victim" location dispatched to the swarm. Fixed by requiring finite `confidence` + finite position components (fail-closed drop). MEASURED fails-on-old: `test_nan_victim_position_dropped_from_fusion` produced a non-finite fused position pre-fix. **Dimensions confirmed clean (with evidence):** (a) **MAVLink decode panic-safety** — `SwarmNodeState::decode(&[u8;20])` `try_into().unwrap()`s are over fixed const ranges of a fixed-size array (provably infallible; no arbitrary-length `&[u8]` path exists). (b) **UWB GPS anti-spoofing is NaN-safe** — `(gps_dist - uwb_dist).abs() <= tol` already fails CLOSED on a NaN range/position (counts as inconsistent → spoof rejected), verified by reasoning + existing `test_spoofed_gps_invalid`. (c) **Bounded grid / no allocation-from-length-field** — `ProbabilityGrid::update_bayesian`/`mark_scanned` bounds-check `cx >= width || cy >= height`; `pos_to_cell` uses saturating `as u32` (Rust `as` saturates, no UB). (d) **Mesh `nearest_k` NaN-safe sort** — `partial_cmp(..).unwrap_or(Equal)` cannot panic on NaN distances. (e) **No hardcoded secrets** — `MavlinkSigner` key is constructor-injected (`[u8;32]`), nothing embedded. **Documented-not-fixed (for ADR-176, not churned to avoid test-rewrite risk):** (i) **Raft `AppendEntries` lacks the Log-Matching consistency check** (`topology/raft.rs:187`) — a follower appends leader entries on `term >= current_term` without validating `prev_log_index`/`prev_log_term`, so a malformed/byzantine leader can corrupt a follower's log (a genuine consensus-safety gap; vote tallying is also delegated to the caller per the existing `handle_message` comment). (ii) **`MavlinkSigner::verify` uses a non-constant-time tag `==` and has no replay/timestamp-window rejection** (`security/mavlink_signing.rs:64`) — the doc comment already flags the replay limitation as a known demo/test simplification. `cargo test -p ruview-swarm --no-default-features`: **117 → 123 passed, 0 failed** (+6 pins). Workspace green; Python deterministic proof unchanged (`f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a`, bit-exact — `ruview-swarm` is off the signal proof path). +- **`nvsim` (ADR-089 NV-diamond magnetometer simulator) beyond-SOTA security review — two real degenerate-input findings fixed (config-induced panic/DoS + NaN-state-poisoning silent-corruption), each pinned by a fails-on-old test; determinism integrity, panic-free deserialisation, and RNG-seeding confirmed clean with evidence. Needs ADR slot 177.** Beyond-SOTA review of the standalone WASM-ready forward-only pipeline (`scene → source → propagation → NV ensemble → digitiser → MagFrame + SHA-256 witness`). The real risk surface is degenerate physical-parameter input (the scene + config are the external boundary, especially via the WASM `config_json`/`scene_json` entry points). **Finding 1 — NVSIM-DT-01 (config-induced panic / DoS, MEDIUM; `pipeline.rs:58,95`).** `dt` was derived as `config.dt_s.unwrap_or(1.0 / f_s_hz)`; an externally-supplied `f_s_hz == 0.0` makes `dt == +Inf`, `(dt*1e6) as u64` saturates to `u64::MAX`, and `(sample as u64) * dt_us` then **panics `attempt to multiply with overflow`** for `sample >= 2` (MEASURED: probe panicked at `pipeline.rs:95:30` under the debug/test profile; in `panic=abort` WASM this aborts the module, in release it silently wraps `t_us` to garbage). **Fixed** by sanitising `dt` (non-finite/non-positive → 1 µs fallback), capping the `u64` cast at `u64::MAX`, and using `saturating_mul` for the timestamp so no config can ever overflow it. **Finding 2 — NVSIM-NAN-01 (NaN-state-poisoning silent corruption, MEDIUM; funnel at `digitiser.rs::adc_quantise`).** A non-finite scene parameter (e.g. a `NaN`/`Inf` dipole **position**, `Inf` **moment**, or `NaN` loop **radius**) flows through `scene_field_at` and **bypasses the near-field clamp** — `NaN < R_MIN_M` is `false`, so the `1/r³` path is taken and produces a `NaN`/`Inf` field (MEASURED: `b=[NaN,NaN,NaN], sat=false`). At the ADC that non-finite value hit the `else` branch and **`NaN as i32 == 0`** (Rust saturating cast), emitting a frame with `b_pt=[0,0,0]` and **the `ADC_SATURATED` flag CLEAR** — a frame *indistinguishable from a legitimate zero-field reading* (MEASURED: `b_pt=[0.0,0.0,0.0] flags=0b0000`). This is the same NaN-poisoning class flagged across the calibration/vitals crates; the `propagation` module already guards its NaN paths, but the source→ADC path did not. **Fixed** at the single funnel point: `adc_quantise` now treats any non-finite input as out-of-range → clamps to code `0` **and raises the saturation flag**, so the corruption is visible downstream (the pipeline's existing `adc_sat` OR-reduction propagates `ADC_SATURATED` onto the frame). **Dimensions confirmed clean (with evidence):** (1) **Determinism integrity — clean.** The only RNG is `ChaCha20Rng::seed_from_u64(seed)` fully seeded from the caller's `u64` (grep: one `seed_from_u64`, zero `thread_rng`/`getrandom`/`SystemTime`/`Instant`/`HashMap`); Cargo.toml pins `rand`/`rand_chacha` with `default-features=false` (no OS-entropy path). Box–Muller draws from `gen_range(f64::EPSILON..=1.0)` (avoids `ln(0) = -Inf` by construction). Frame serialisation is fixed little-endian; source summation order is fixed by `Vec` order. The published cross-machine witness `cc8de9b0…93b4` (`proof::tests::proof_witness_publishes_a_known_value`) **still passes unchanged** after both fixes — the happy-path output is byte-identical, confirming the guards only affect degenerate inputs. (Attested caveat, not a finding: libm `cos`/`ln`/`sqrt` *could* differ x86↔wasm; witness is documented as x86_64-captured.) (2) **Panic-free deserialisation — clean.** `MagFrame::from_bytes` validates `len`/magic/version, then the per-field `buf[a..b].try_into().expect(...)` calls are over **fixed sub-ranges of an already-length-checked 60-byte buffer** → provably infallible, not reachable panic vectors. No `unsafe`, no `panic!`/`unreachable!` in production code; every other `unwrap`/`expect` is `#[cfg(test)]`. (3) **Div-by-zero — clean.** `dipole_field`/`current_loop_field` clamp `r_norm < R_MIN_M` (1 mm) before the `1/r³`/`1/r²` divide (finite inputs); `shot_noise_floor` guards `denom <= 0.0 → f64::INFINITY`; `vec3_normalise` guards `n < 1e-20`. (The only gap was the NaN case that *bypasses* the `r_norm` clamp — fixed at the ADC funnel above.) **Pinning tests (fails-on-old / passes-on-new, MEASURED):** `pipeline::degenerate_zero_sample_rate_does_not_panic` (panicked on old code; now finite frames), `pipeline::non_finite_scene_input_flags_frame_instead_of_silently_zeroing` (old: `flags=0b0000`; now `ADC_SATURATED` set, `b_pt` finite), `digitiser::adc_quantise_flags_non_finite_as_saturated` (old: `(0,false)` for NaN; now `(0,true)`). `cargo test -p nvsim --no-default-features`: **50 → 53 passed, 0 failed**. Workspace green; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — nvsim is off the signal proof path). Needs ADR slot 177. +- **`wifi-densepose-core` + `wifi-densepose-cli` beyond-SOTA security review (ADR-127 note; CLI needs ADR slot) — NaN-state-poisoning bug class does NOT originate in core (verdict: no + evidence); both crates confirmed clean on all reviewed dimensions; 4 regression pins added locking in two real DoS guards.** **Load-bearing question — verdict NO (with evidence, MEASURED).** The NaN-state-poisoning class that hit `wifi-densepose-calibration`/`-vitals`/`-geo` (a non-finite input latching into a persistent IIR/Welford/von-Mises/voxel accumulator → silent permanent feature failure) does **not** live in a shared `wifi-densepose-core` primitive: core exposes **no stateful accumulator at all** — no Welford/running-mean, no von-Mises/circular-mean, no IIR/biquad filter state, no voxel grid. Grep over `core/src` for `welford|von_mises|biquad|y1|y2|running_mean|accumulat|voxel|self.*+=` matched only the `InvalidState` *error* enum, "reset state" doc comments, and a test-only LCG — zero stateful logic (MEASURED). Each downstream crate rolls its own accumulator, so each fix is correctly local; corroborated by `wifi-densepose-calibration::Features::from_series`, which **already** filters non-finite samples and returns `Features::ZERO` (the downstream re-implementation of the fix). The only float math in core's hot path is construction-time projection (`CsiFrame::new` → `amplitude`/`phase` via `mapv`) and pure stateless `utils` functions — none persists state across frames. **Dimensions confirmed clean (with evidence):** (1) **panic-on-adversarial-input = 0** — `CsiFrame::from_canonical_bytes` (the replay/forward deserialisation boundary) returns a typed `CanonicalDecodeError` for every malformed input (truncation, bad discriminant, non-UTF-8 device id, nonzero reserved bytes, shape/payload mismatch, trailing bytes); the CLI UDP parser `parse_csi_packet` (the widest CLI attack surface — bound to `0.0.0.0` by default) returns `None` on any malformed datagram. Both proven panic-free over deterministic-LCG fuzz sweeps (new pins). (2) **`Confidence::new` rejects NaN** (`!(0.0..=1.0).contains(&NaN)` ⇒ `true` ⇒ `Err`); `compute_bounding_box`/`to_flat_array` are NaN-tolerant (f32 `min`/`max` ignore NaN). (3) **`amplitude_variance`/`mean_amplitude` panic-free on empty frames** — ndarray 0.17 `var(0.0)`/`mean()` return finite/`None` (handled), not a panic (MEASURED via throwaway probe). (4) **Unbounded-memory DoS bounded** in both deserialisers: `from_canonical_bytes` guards the `Vec::with_capacity(rows*cols)` with `rows.saturating_mul(cols).saturating_mul(16) <= bytes.len()`; `parse_csi_packet` guards `Array2::zeros` with `buf.len() < 20 + n_pairs*2` — a header lying about an enormous `rows×cols` / `n_antennas×n_subcarriers` is rejected before allocation. (5) **CLI path-traversal** in `calibrate-serve` already defended by `sanitize_room_id` (keeps `[A-Za-z0-9_-]`, caps 64 chars, with tests) on every client-supplied `room_id`/`bank`/`baseline` name that reaches a file path; bearer-auth gate + non-loopback-bind warning present. (6) **No hardcoded secrets** (`--token` read from `CALIBRATE_TOKEN` env, never embedded). **Regression pins added (fails-on-old / passes-on-new):** core `canonical_decode_oversized_shape_is_bounded_not_allocated` (MEASURED: with the saturating guard removed it panics `capacity overflow` at `types.rs:801`; passes with the guard) and `canonical_decode_never_panics_on_arbitrary_bytes`; CLI `test_parse_csi_packet_oversized_claim_is_rejected_not_allocated` (a 255×65535-pair claim ≈ 33 MB in a 2 KB datagram → `None`, never OOMs) and `test_parse_csi_packet_never_panics_on_arbitrary_bytes`. `cargo test -p wifi-densepose-core`: **35 → 37** lib tests, 0 failed; `cargo test -p wifi-densepose-cli --no-default-features`: **24 → 26**, 0 failed. Workspace green; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — core/cli are off the signal proof path). No production code changed — review is clean-with-evidence plus pins. +- **`homecore` foundational state-machine review (ADR-127) — one real concurrency bug fixed (state-set TOCTOU dropping/reordering `state_changed` events) + two hardening fixes (entity_id memory-DoS, service-handler panic isolation), each pinned by a fails-on-old test; event-bus lag & lock discipline confirmed clean with evidence.** Beyond-SOTA security+concurrency review of the crate every other HOMECORE module builds on (state store `state.rs`, event bus `bus.rs`, service/entity registries, the `HomeCore` coordinator), un-covered by the ADR-154–159 sweep — a bug here is high-blast-radius. **HC-RACE-01 (state-set TOCTOU, the crux — race/lost-event).** `StateMachine::set` did `get()` (releasing the DashMap shard lock) → compute the next snapshot + the no-op/`last_changed` decision → `insert()` (re-acquiring the lock) → `send()`; the read-modify-write was **not atomic** w.r.t. a concurrent writer on the same entity, contradicting ADR-127 §2.1's promise that "the writer atomically replaces the map entry." A writer that read a **stale `old`** could mis-classify a genuine transition as a no-op and **silently drop its `state_changed` event** (a missed automation trigger) or fire an event whose `new_state` duplicated the previously delivered one (a spurious trigger for any automation keyed on `old_state != new_state`). **Fixed** by holding the shard write-lock across the whole read→decide→insert→fire sequence via `entry()`/`insert_entry()` — `tx.send` is non-blocking, non-async, and never re-enters the map, so firing under the shard lock cannot deadlock and keeps global event order in lock-step with global commit order. Pinned by `concurrent_set_fires_no_duplicate_adjacent_events` (4 writers toggling one entity A/B; asserts no two consecutive fired events carry an identical `new_state` — impossible under correct serialisation; an instrumented probe observed ~93k such duplicate-adjacent events across 200 trials on the racy code, **zero** on the fix; the test fails reliably on the first trial pre-fix). **HC-EID-LEN-01 (unbounded `entity_id`, memory-DoS).** `homecore-api/src/rest.rs` parses untrusted REST path segments straight through `EntityId::parse`; with no length cap an otherwise-valid id (`a.` + many MB of `[a-z0-9_]`) was accepted, and a `POST /api/states/` would persist it into the DashMap state store (permanent growth across distinct ids). **Fixed** by rejecting ids longer than `MAX_ENTITY_ID_LEN` (255, HA-compatible) up front in `parse()`, before any per-char scan, with a new `EntityIdError::TooLong` — fail-closed at the boundary type protects every caller (REST, registry deserialize, automation). Pinned by `entity_id_length_boundary` (exactly-MAX accepted; MAX+1 and a 4 MiB id rejected — oversized parses `Ok` on old code). **HC-SVC-PANIC-01 (service-handler panic not isolated).** `ServiceRegistry::call` already ran handlers **outside** the registry lock (the `Arc` is cloned out of the read guard first → no `RwLock` poisoning, no blocking of other callers — clean), but a panicking handler unwound through `call()` into the caller's task (the task driving the engine). **Hardened** by wrapping the handler future in `AssertUnwindSafe` + `catch_unwind`, converting a panic to `ServiceError::HandlerPanicked`; the registry stays fully usable (a sibling healthy service still returns, the bad service stays registered). Pinned by `panicking_handler_is_isolated_and_registry_survives` (unwinds through `call` on old code). **Dimensions confirmed clean (with evidence, no invented issues):** (1) **event-bus bounds / lag** (the homecore-api WS lag-DoS class) — both `StateMachine` and `EventBus` use **bounded** `tokio::sync::broadcast` (capacity 4,096); a slow subscriber gets a recoverable `Lagged(n)` (drop-oldest + re-sync) while `fire_*` is non-blocking and never waits on slow receivers, so a lagging subscriber **cannot block the publisher, grow the channel without bound, or kill a fast subscriber** (evidenced by `slow_subscriber_does_not_block_publisher_or_kill_the_bus` — fire 3× capacity at an idle subscriber, publisher unblocked, bus stays live, fresh fast subscriber receives, lagged one recovers); (2) **lock ordering / lock-across-await** (deadlock) — no code path holds two of `{state DashMap, registry RwLock, service RwLock}` simultaneously, so no inconsistent-ordering deadlock can exist; every `tokio::sync::RwLock` guard in `registry.rs`/`service.rs` is used in one synchronous statement and dropped before any `.await` (`call` explicitly scopes the read guard out before awaiting the handler); the only guard held across a send is the DashMap shard lock in `set`, across a **synchronous** broadcast send — safe; (3) **panic-on-input** — no reachable `unwrap`/`expect`/index in non-test code beyond the safe `send().unwrap_or(0)` and the dead-but-harmless `split_once(...).unwrap_or(...)` fallbacks on already-validated ids. `cargo test -p homecore --no-default-features`: **20 → 24 passed, 0 failed** (+4 pins). Workspace green; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — `homecore` is off the signal proof path). Review notes appended to ADR-127 §9. +- **`homecore-migrate` security review (ADR-165 surfaces) — one real secret-leak fix; traversal / data-loss / panic / injection dimensions confirmed clean with evidence.** Beyond-SOTA review of the Home-Assistant `.storage`/`secrets.yaml`/`automations.yaml` migrator, the two sharp surfaces being secret handling (`secrets.rs`) and untrusted-file parsing. **Finding + fix (secret-leak, `secrets.rs`):** a malformed `secrets.yaml` whose offending scalar fails a typed-tag coercion (e.g. `port: !!int `) produced a `serde_yaml` error whose message **embeds the scalar verbatim** — `invalid value: string ""`. The old code wrapped that message into `MigrateError::YamlParse { source }`; the error propagates out of `read_secrets`, is `?`-returned by the `InspectSecrets` CLI path in `main.rs`, and printed to stderr by `anyhow` — **leaking a secret value despite the CLI's deliberate `` design** (`main.rs` only ever prints keys as ` = `). Fix: `secrets.yaml` parse failures now map to a dedicated redacting variant `MigrateError::SecretsParse { path, line, column }` carrying only the file path + a coarse location (from `serde_yaml::Error::location()`), never the scalar; other (non-secret) YAML files keep `YamlParse`. **Pinned** by `secrets::tests::malformed_secrets_error_never_contains_secret_value`, which asserts the rendered error **and its full `#[source]` chain** never contain the secret value and that the error is still the structured `SecretsParse` (fail-closed) — it **fails on the old `YamlParse` path** (observed leak: `... invalid value: string "s3cr3t_TOKEN_VALUE" ...`) and passes on the fix; plus `malformed_secrets_error_reports_location` (still locatable). **Confirmed clean with evidence:** *secret leakage elsewhere* — the only secret sink is the value map; `main.rs` redacts values, and the `MissingField`/`Io` paths surface only the path, never content. *Source mutation / data-loss* — **structurally impossible**: there is no `fs::write`/`fs::remove`/`fs::create`/`File::create`/`OpenOptions` anywhere in the crate; P1 reads source and writes nothing (`import-entities` is in-memory only), so re-runs are trivially idempotent and the HA source is never touched. *Path traversal* — CLI takes a `--config-dir`/`--storage` dir and joins **fixed** filenames (`secrets.yaml`, `core.entity_registry`, …); no user-controlled path component, no `..`/absolute escape beyond the user's own privileges. *Panic-on-input* — probed duplicate-key, bad-indent, tab/control-char, multi-doc, non-mapping-root, unterminated-flow, `!input` blueprint tags, deep nesting, anchors: **every** malformed/typed/truncated input **errors, never panics** (all production code is panic-free; every `unwrap`/`expect` is `#[cfg(test)]`). *Fail-closed versioning* — unknown storage `minor_version` hard-errors (no silent fallback to an older parser). *Injection* — no SQL/shell/path interpolation; the tool emits diagnostics only and persists nothing in P1. `homecore-migrate` **19 → 21** tests (`--no-default-features`), 0 failed. Behaviour otherwise unchanged; Python deterministic proof PASS, hash unchanged (`homecore-migrate` is off the signal proof path). +- **`homecore-recorder` security review (ADR-132 surfaces) — two real bounding fixes; SQL-injection & NaN-index dimensions confirmed clean with evidence.** Beyond-SOTA review of the HA-compat state recorder (DB persistence + history + ruvector semantic search), the crux being its DB-backed SQL-injection surface. **Findings + fixes:** (1) **Memory-DoS — unbounded `get_state_history`.** The history query carried no `LIMIT`, so a wide `[since, until]` window over a high-frequency entity (a per-second sensor ≈ 86k rows/day) would load an unbounded row set into a single in-memory `Vec`. Added a hard `LIMIT MAX_HISTORY_ROWS` (1,000,000 — generous enough never to truncate a realistic history graph, bounded enough to cap the worst case); the sibling search paths were already `k`-bounded. (2) **Disk-DoS / documented-but-missing `purge`.** The README + HA-compat table advertised `Recorder::purge(older_than)` as a capability, but **no such method existed** — i.e. no retention path at all → unbounded disk growth. Implemented a **transactional** `purge` that deletes `states` + `events` strictly **older than** the cutoff (**exclusive** boundary — idempotent, no off-by-one; a row at the cutoff instant is kept) and **garbage-collects** orphaned `state_attributes` blobs (a dedup-shared blob is dropped only once its last referencing state is gone); all three deletes run in one transaction so a mid-purge failure rolls back cleanly (no states-deleted-but-events-kept corruption). **Confirmed clean with evidence:** SQL injection — **every** query in `db.rs` uses bound `?` parameters (no `format!`/string-concat of user data into SQL); the lone `format!` builds the LIKE *pattern*, which is itself bound as a parameter with `ESCAPE '\\'` and metacharacter escaping. Pinned: a state value `'; DROP TABLE states; --` is stored/queried **literally** (table survives), and a `%`/`_` in a search query matches **literally**, not as a wildcard. NaN-index poisoning (the calibration/vitals/geo class) — **structurally impossible** here: embeddings are SHA-256 → `i32` → `f32` (an `i32` cast to `f32` is always finite, never NaN/Inf), with an all-zero-digest norm guard; probed empty-index search, empty-string query, and `k=0` — all return `Ok(0)`, **no panic**. Fail-closed write path — a removal event yields `Ok(None)`, semantic-index failure is logged not propagated (best-effort, never blocks the durable SQLite write), and `EntityId` parsing failures fall back rather than panic. **6 new pinning tests** (SQL-injection literal-storage, LIKE-metacharacter literalness, history `LIMIT`, purge exclusive-boundary, purge attribute-GC-keeps-shared, purge old-events): `homecore-recorder` **19 → 25** (`--no-default-features`) / **25 → 31** (`--features ruvector`), 0 failed; the purge-boundary test is a true pin (fails deleting 2 rows under an inclusive cutoff, passes deleting 1 under the exclusive cutoff). Behaviour otherwise unchanged; Python deterministic proof unchanged (recorder is off the signal proof path). + +### Added +- **ADR-184 / ADR-185 / ADR-186 / ADR-187 decision records added under `docs/adr/`** (indexed in the ADR README, count corrected to 193 — commit `cca5bd811`). **ADR-184** (PyPI Trusted Publishing, completes ADR-117) — Proposed; its CI migration has landed but is pending pypi.org registration (see Changed). **ADR-185** (P6 Python bindings for AETHER/MERIDIAN/MAT) and **ADR-186** (training progress API, refs #1233) are **Proposed only** — decision records for work not yet implemented on this branch. **ADR-187** (archive/v1 deprecation + model-weights honest labeling) — Accepted and implemented (see Deprecated). +- **ADR-263/264/265: deep review of the RuView npm surface (`@ruvnet/ruview`, `@ruvnet/rvagent`, `@ruv/ruview-cli`) with optimization strategies recorded as ADRs.** ADR-263 reviews the published `@ruvnet/ruview@0.1.0` harness: fail-open `claim-check` on empty input (HIGH), `spawnSync` head-of-line blocking of the MCP stdio server during long `verify`/`calibrate` runs (HIGH), optionalDependencies tripling the cold `npx` install for a code path that never uses them (MEASURED, `npm i` in a clean prefix: 4 packages / 620 kB / 71 files default vs 1 package / 172 kB / 22 files with `--omit=optional`), 1 MiB `maxBuffer` truncation risk, `python -c` port-interpolation surface in `node_monitor`, hardcoded MCP server version, duplicated skill payload — optimizations O1–O8. ADR-264 reviews `@ruvnet/rvagent@0.1.0` + the private CLI **against the published registry tarball**: `exports.require` → nonexistent `dist/index.cjs` (HIGH, every CJS consumer breaks), 44 dead source-map files = 62,698 B of the 188 kB unpacked payload pointing at unshipped `../src` (MEASURED), stdio-only server described as "dual-transport" (CLAIMED capability), mixed dot/underscore tool naming, double Zod validation + hand-duplicated advertised schemas, 2-fd leak per training job, unbounded request body in the unwired HTTP scaffold, dead `detectCogBinary` candidate list, `ruview` bin-name collision — optimizations O1–O9. ADR-265 adds the cross-cutting distribution layer: an `npm-packages.yml` CI matrix (tests + pack-content/size gate + tarball-install smoke test — none of the three packages currently has any CI, and `ci.yml` pins Node 18 against `engines >= 20`), publish-from-CI-only with `npm publish --provenance`, version single-sourcing from package.json, bin/namespace ownership (the `ruview` bin belongs to `@ruvnet/ruview`), and claim-check enforcement on package READMEs/descriptions. Docs only — no runtime code changed; the findings are the work orders for the follow-up PRs. +- **ADR-131 §11–§12: HOMECORE-UI wired to a real backend — single-origin BFF gateway + production front-end (no mock in prod).** Implements the §11 wiring decision so the dashboard stops rendering fabricated data. **Front-end (DONE + verified under Node):** `api.js` rewritten so every data accessor is async and calls the §11.2 gateway routes; the in-browser mock is demoted to a **dev-only fixture** reachable only via `?demo=1`/`HOMECORE_UI_DEMO` (§2.2); all ten panels now `await` and render a **typed empty/error state** on upstream failure (no mock fallback in production) — 3 panels converted by hand, 7 via a parallel agent swarm. **New `homecore-server` BFF gateway (`src/gateway.rs`, compile-pending — no Rust toolchain in the authoring env):** promotes `homecore-server` to the single origin (§2.1); adds `/api/homecore/*` + `/api/cal/*` merged into `build_app`, with `reqwest` + CLI/env flags (`--calibration-url`/`--calibration-token`/`--apps-dir`/`--gateway-timeout-ms`). Real handlers: calibration **reverse-proxy** (W2), `GET /api/homecore/rooms` with the §11.3 **RoomState adapter** (`breathing`→`breathing_bpm`, `heartbeat`→`heart_bpm`, `None`→`null` preserving not-trained-vs-withheld, injected `anomaly.threshold`/`room_id`), **COG supervisor** over `/var/lib/cognitum/apps/` (W4), and **appliance metrics** from `/proc` + TCP service probes (W6); SEED-device/appliance routes (seeds/federation/witness/privacy/settings/automations/events-history/hailo/tokens — W3/W5) return a typed `503 upstream_unavailable` and the UI shows error states. **Tests:** front-end **5 files green** — import-graph, boot, render-smoke (22), interaction (3), and a **new prod-errors suite (13)** that runs with demo OFF + gateway unreachable and proves every panel renders an error state, never mock, never throws (it caught + fixed a real unhandled-rejection in the events automation builder). **Gateway compiled, tested, and run on Rust 1.89:** `cargo test -p homecore-server --no-default-features` = **12/12 pass** (6 gateway + 6 UI mount); the binary was **run live** — `GET /api/homecore/appliance` returns real `/proc` metrics + TCP service probes, unauth → `401`, `cogs` → `[]` (no apps dir), SEED-tier → typed `503`, and against a mock calibration upstream the `/api/cal/*` proxy passes through (`200`) and `GET /api/homecore/rooms` adapts `RoomState` to the UI shape (`breathing`→`breathing_bpm`, `heartbeat:null`→`heart_bpm:null`, injected `anomaly.threshold`/`room_id`). **Live testing caught + fixed a real bug** — a double-`v1` segment in the `/api/cal/*` proxy URL. **Remaining (intrinsic, not an env limit):** W3/W5/W6-Hailo/federation depend on services/hardware **not in this repo** (recorder/automation HTTP wrappers, real SEED nodes, Hailo stat source), so they return honest `503`s rather than fabricate data; W1/W2/W4/W6-appliance are functional now. ADR-131 §10/§12.1 updated with per-wave status. +- **ADR-131: HOMECORE-UI — the complete operational dashboard for the two-tier Cognitum stack, served by `homecore-server` at `/homecore`.** A zero-dependency, no-build-step vanilla TS/JS + CSS frontend (the `rufield-viewer` "Axum + vanilla-JS" pattern) that extends the Cognitum Appliance shell as a first-class nav section (Framework | Guide | Cog Store | **HOMECORE** | Status). **Complete, not a scaffold** (per the ADR's revised §2/§7): all **10 panels** ship fully built and rendered — §4.1 System Dashboard (v0 Appliance health strip + SEED fleet grid + ESP32 summary + COG status row + event-bus sparkline), §4.2 SEED Detail (vector store / witness chain / 5 onboard sensors / reflex rules / cognitive-fragility / ingest packet-type), §4.3 SEED Fleet Map (Appliance→SEED→ESP32 hierarchy, ESP-NOW mesh, cross-SEED fusion badges, ADR-105 federation), §4.4 Entity & State Browser (domain-grouped, **live WebSocket `subscribe_events` patching — never polls**, first-class provenance badges, keyword filter, context-causality slide-over), §4.5 RoomState/Sensing (mixture-of-specialists), §4.6 COG Management + App Registry, §4.7 Calibration Wizard (5-step baseline→enroll→train→verify), §4.8 Event Bus + Automation builder, §4.9 Witness/Audit log (two-tier SHA-256 + Ed25519 timeline, privacy-mode banner, pagination, export), §4.10 Settings. **Design system is the exact production Cognitum palette** (`tokens.css` carries `--cyan #4ecdc4` … `--r 10px` verbatim, §3.1) so there is no visual seam with the Cog Store (§3.3 invariant). **§6 UX invariants enforced in code and pinned by tests:** tier-origin provenance is always-visible (never collapsed); `stale`/`vetoed` flags and the kNN fragility score are prominent (amber/red tint + banners, never grey-on-grey); a `null` specialist renders "Not trained / calibrate to enable" **visually distinct from** veto-`withheld` (rendered as explicitly withheld, never zero) **distinct from** an error; all IDs/hashes/endpoints/payloads use `--mono`; Hailo-sourced COGs (`arch: hailo10`) are visually distinguished from CPU-only (`arch: arm`). **Wiring:** `homecore-server` gains a `--ui-dir`/`HOMECORE_UI_DIR` flag and mounts the assets via `tower-http` `ServeDir` at `/homecore` alongside the unchanged HA-compat `/api` surface (new testable `build_app()`), with **5 Rust integration tests** (`#[cfg(test)] mod ui_tests`, `tower::oneshot`) asserting index / design tokens / all-10-panels are served, the API coexists, and an empty `--ui-dir` disables the mount. **JS test + benchmark suite (`ui/`, runs under plain `node`, no npm install): 24 checks / 0 failed** — an import/export graph verifier (15 modules consistent), a DOM-shim render-smoke that *executes every panel* (21 checks: ui helpers + mock contracts + all 10 panels render without throwing), and an interaction suite (3 checks: live WS state-patch, ws.js handshake/parse, calibration backend contract). **Benchmark:** total bundle **136.8 KB uncompressed across 18 files — ~37× smaller than HA's ~5 MB Lit bundle** (the ADR-126 §1.1 foil), slowest panel **1.5 ms/cold-render**. **Honest scope (§7.1):** the live HOMECORE REST API (`/api/config|states|services`) and the WebSocket `subscribe_events` feed are driven for real; panels whose backing service is **not** in this binary (SEED HTTPS API, calibration ADR-151, ADR-105 federation) render against a **contract-conformant mock layer flagged with a DEMO banner** and swap to live the moment those endpoints land — no mock data is ever presented as real. **Not verified in this environment:** the Rust crate was edited and the integration tests written but **not compiled/run here** (no Rust toolchain present); `cargo test -p homecore-server` + `cargo build` must be run on a Rust host before merge. +- **ADR-175: int8 quantization of the WiFlow-STD "half" pose model — MEASURED fp32-vs-int8 accuracy/size trade-off (honest negative).** Sub-deliverable 8.2 of the benchmark/optimization milestone, and the reading of the SOTA brief's "one untested edge lever" (QAT-int8 on the 843,834-param half model that strictly dominates the published 2.23M model). A new committed script `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py` quantizes `half_best.pth` to int8 two ways and scores both with the **same** upstream `calculate_pck`/`calculate_mpjpe` that produced the fp32 sweep numbers, under **one locked normalization** (ADR-173 torso-diameter PCK — neck idx2→pelvis idx12, `use_torso_norm=True`, the standard MM-Fi/GraphPose-Fi convention), on the **same** seed-42 file-level 70/15/15 test split (52,560 NaN-free / 54,000 full windows). **MEASURED on ruvultra (RTX 5080, torch 2.11.0+cu128, fbgemm; clean test, torso-PCK):** fp32 = 96.62% PCK@20 / 99.47% PCK@50 / 0.008981 MPJPE / 3.351 MB (fp32-CPU reproduces fp32-GPU to 4 dp, so the int8 deltas are pure quantization, not CPU/GPU drift); **int8 static PTQ = 40.98% PCK@20 (−55.64 pp), 1.046 MB** — naive static QDQ **collapses** on this model (the brief's 2.23M "sweet spot" does NOT transfer to the 843k half model at the tight @20 threshold); **int8 QAT (3-epoch FX fake-quant fine-tune from half_best) = 67.48% PCK@20 (−29.15 pp) / 98.69% PCK@50 (−0.78 pp), 1.043 MB.** **Verdict (honest no):** int8 is **not a win** at the strict PCK@20 edge target — QAT recovers a large share of the PTQ collapse and is near-lossless at the loose PCK@50 (coarse localization survives int8, fine does not), but a **3.2× size win at −29 pp PCK@20** is a bad trade when the half model already fits edge flash at fp32 → **keep fp32/fp16 on the edge for now.** **Disclosed gap:** the QAT *fake-quant* val PCK@20 reached 83.45% but the *converted* int8 model scores 67.48% — a real ~16 pp `convert_fx` gap (fbgemm int8 kernels ≠ straight-through estimate, esp. the axial-attention einsum/softmax); we report the converted-int8 number, not the fake-quant proxy. **MEASURED:** every table number + the PTQ collapse + the QAT partial recovery + the conversion gap. **CLAIMED/not done:** ONNX/TFLite export, on-edge-SoC latency/energy (int8 measured on x86 fbgemm — size transfers, latency does NOT), mixed-precision keeping attention fp32, longer/better-tuned QAT. **Honest limitations:** single in-domain eval split (no cross-environment split), x86-int8 not edge-SoC-int8, lightly-tuned QAT. Additive only — no production Rust or signal-pipeline change; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — off the signal proof path). +- **Metric-locked PCK/MPJPE accuracy harness — resolves the PCK-definition ambiguity (`wifi-densepose-train`, needs ADR slot 173).** The SOTA brief (`docs/research/sota-nn-train-benchmark-brief.md` §1, §3.1, §4) found the single biggest threat to any "beyond-SOTA" claim is **metric ambiguity**: three PCK@20 figures (96.09% WiFlow-STD image-normalized, 81.63% AetherArena torso-PCK, 61.1% GraphPose-Fi standard PCK) cannot be lined up because each silently uses a different normalization — the project was retracted twice over this (a withdrawn "92.9%" used *absolute* pixels, not torso). New `src/accuracy.rs` makes the normalizer **explicit, selectable, and carried with every reported number**: a `PckNormalization` enum (`TorsoDiameter` = standard MM-Fi/GraphPose-Fi hip↔hip; `BoundingBoxDiagonal` = looser WiFlow-STD image-normalized; `AbsolutePixels(threshold)` = the retracted convention, included so historical numbers are reproducible and clearly labeled non-comparable); one canonical `pck_at(pred, gt, vis, k, normalization)` reusing the `metrics_core` geometric primitives (hip distance, bbox diagonal — no duplicate kernel); `mpjpe(pred, gt, vis)` (2D/3D, mm); and a self-describing `PoseAccuracy { pck_at: BTreeMap, mpjpe, normalization, n_keypoints, n_frames }` returned by `accuracy_report(frames, ks, normalization)` so an **unlabeled PCK number is structurally impossible**. **17 hand-computed deterministic tests** (no GPU, no datasets) prove the harness arithmetic: perfect→PCK=1.0/MPJPE=0; all-just-outside→0.0; half-in-half-out→0.5; the **key proof** that identical predictions score 0.50 (torso) / 1.00 (bbox) / 0.75 (abs) under the three normalizations (the ambiguity is real and the definitions are distinct); MPJPE 2D/3D fixtures; and graceful degenerate handling (zero torso, empty frames, NaN coords — no panic, never a false-perfect). **This is measurement infrastructure, not an accuracy claim** — the tests prove the harness is correct, not that any model is good. `wifi-densepose-train` lib 191→206, `test_metrics` 12→14, 0 failed. Python deterministic proof unchanged (off the signal proof path). +- **CI bench-regression guard (`.github/workflows/bench-regression.yml`) — wires the v2/ criterion benches into CI as a real, hard-failing COMPILE-VERIFY gate + an informational fast-run; caught + fixed one already-bit-rotted bench (benchmark/optimization milestone sub-deliverable 8.3; needs ADR slot 174).** The v2/ workspace ships **26 criterion benches across 18 crates** (e.g. `nvsim/pipeline_throughput`, `wifi-densepose-ruvector/{ann,sketch,fusion}_bench`, `wifi-densepose-signal/{signal,dsp_perf,features,calibration,aether_prefilter,cir}_bench`, `wifi-densepose-mat/detection_bench`, `wifi-densepose-nn/{inference,native_conv,onnx}_bench`, `wifi-densepose-engine/engine_cycle`, …) but, because benches are **not** part of `cargo test`, nothing in CI compiled them — so they silently rot when a public API they call changes. **Proof this matters (MEASURED):** running the new gate on the current tree immediately caught `wifi-densepose-mat/detection_bench` failing to compile (`E0063: missing field last_rssi in initializer of SensorPosition` — the struct gained a field, the bench was never updated); fixed in this change (`last_rssi: None`, the simulated-zone convention) and re-verified (`cargo bench -p wifi-densepose-mat --no-default-features --bench detection_bench --no-run` → `Finished`, Executable produced). **HONEST SCOPE — what gates vs what is informational:** (1) `bench-compile` (HARD GATE) runs `cargo bench --workspace --no-default-features --no-run` (compile + link every default-feature bench, no measurement) plus a `--features cir` compile of the gated `cir_bench` — a deterministic, real regression guard against bench bit-rot; (2) `bench-fast-run` (INFORMATIONAL, `continue-on-error: true`, NEVER gates) runs a curated pure-CPU subset (`nvsim/pipeline_throughput`, `ruvector/{sketch,fusion}_bench`) in criterion quick-mode (1s warm-up / 2s measure / 10 samples), targeted per-`--bench` (the crates' libtest lib targets reject criterion flags), and uploads the logs as an artifact. **No timing-regression gate, by design and stated in the workflow header:** wall-clock on shared GitHub runners varies 2-3x run-to-run, so a hard threshold or a cross-runner `criterion --baseline` compare would manufacture false failures; that becomes honest only on a frequency-pinned self-hosted runner (documented as the re-add condition). The `crv`-gated `ruvector/crv_bench` is deliberately NOT compiled by the gate because its crates.io dep `ruvector-crv 0.1.1` currently fails to build on stable (upstream E0308 in its own `stage_iii.rs`) — noted in-workflow with the re-add condition. Checkout is `submodules: recursive` (the workspace path-deps `vendor/rufield`) and installs the Tauri/GTK dev libs like `ci.yml`'s rust-tests job (a `--workspace` bench link pulls the whole graph). **MEASURED locally (Windows, `--no-default-features`):** `nvsim`, `wifi-densepose-ruvector` (sketch/fusion/ann), `wifi-densepose-signal/cir_bench`, `wifi-densepose-mat/detection_bench` (post-fix), `wifi-densepose-vitals/vitals_bench`, and `ruview-swarm/swarm_bench` all compile + the fast subset runs (sample baseline: `nvsim pipeline_run/d1/256` ≈ 55 µs, `d16/1024` ≈ 315 µs; `ruvector sketch_hamming` ≈ 3-7 ns vs `float_l2` ≈ 63-371 ns). The full `--workspace` `--no-run` could **not** be fully validated on Windows (Tauri-`desktop` needs GTK, `candle-core` fails on MSVC, `swarm_bench` LTO-links OOM under parallel pressure) — those are Windows-env artifacts that build in the Linux CI runner (each affected bench was confirmed to compile standalone here). No baseline JSON is committed (a cross-runner baseline would be dishonest). Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — off the signal proof path). +- **RuField `rufield-viewer` live-ingest mode — closes the RuView↔RuField visual loop (ADR-262 surfaces).** The dashboard gains `--source live --upstream `: it consumes RuView's `/ws/field` SSE (falling back to polling `/api/field`), **verifies every event's ed25519 provenance receipt on ingest** (`is_fusable`) — forged/tampered events are flagged ✗ and **never fused** into trusted inferences — and renders real RuView `FieldEvent`s through the same room-state/privacy-badge/fusion-graph/receipt path the synthetic mode uses (wire-compatible by construction: both sides use `rufield_core::FieldEvent` serde). **Strict banner honesty:** a single `BannerState` shows `SYNTHETIC` / `LIVE — ` / `DISCONNECTED — unreachable`, mutually exclusive — never SYNTHETIC while showing live data or vice versa; live mode returns **409** on `/api/run` rather than fabricate a synthetic run, and starts DISCONNECTED until first verified contact. Default stays synthetic. 26 tests / 0 failed. `ruvnet/rufield` `crates/rufield-viewer`; `vendor/rufield` submodule bumped. +- **ADR-262 P3 — live RuField surface: RuView's running sensing-server now speaks RuField on `/api/field` + `/ws/field`.** Wires the P1 `wifi-densepose-rufield` bridge into the live `wifi-densepose-sensing-server` (the bridge is the only added coupling, ADR-262 §5.4). A new `src/rufield_surface.rs` module (kept out of the 8k-line `main.rs`) holds a `FieldSurface` with a **dedicated ed25519 `Signer`**, a bounded ring buffer of recent signed events (`FIELD_RING_CAPACITY = 64`), and the `/ws/field` broadcast topic; it exposes `GET /api/field` (latest signed `FieldEvent`s + signer pubkey + a `dev_signing_key` flag) and `GET /ws/field` (per-cycle stream, mirroring `/ws/sensing`), plus a standalone `router()` for isolated testing. **Tap:** at the ESP32 governed-trust cycle (`main.rs` `observe_cycle` ~`:5886` / `SensingUpdate` build ~`:5938`), `emit_rufield_event` joins the cycle's real `SensingUpdate` (features/classification/signal_field) with the engine's recorded `effective_class`/`demoted` trust state into a `SensingSnapshot` and surfaces a signed `FieldEvent` — **existing endpoints (`/ws/sensing` etc.) are unchanged; this is purely additive.** **Signer (defers the P2 key decision, §8 Q1):** a **standalone dev/sensing key** from `WDP_RUFIELD_SIGNING_SEED` (64-hex or ≥32-byte value), else a deterministic dev default with a logged `WARN` — reusing the `cog-ha-matter` Ed25519 key is the deferred P2 call, so P3 does not pre-empt it. **Egress privacy (fail-closed):** `network_egress_allowed` is *stricter* than `DefaultPrivacyGuard` for an unattended live surface — only **P1/P2** leave the box; P0 (raw) and P3/P4/P5 are held edge-local, so a `Derived → P4/P5` cycle **never** surfaces; no-presence cycles emit **no phantom event**. **P3 acceptance gates (`tests/rufield_surface_test.rs`, 4 integration via `tower::oneshot` + 4 module unit, 0 failed):** a well-formed **signed** event (`Modality::WifiCsi`, P2 not P1, `is_fusable` ed25519-verified, real timestamp); empty cycle → no phantom; **privacy-safety** — an injected `Derived` trust never surfaces; a mixed stream surfaces only egress-safe events. **Honest scope (ADR-262 §0/§6):** real plumbing on a **live endpoint**, **NOT accuracy** — single-link CSI with its existing caveats (no validated room-coordinate accuracy — `field_localize`), a dedicated dev signing key pending the P2 ownership decision, no accuracy claim. The win is narrowly: "RuView's live sensing now speaks RuField on `/ws/field`." +- **ADR-262 P1 — `wifi-densepose-rufield` anti-corruption bridge: RuView WiFi-CSI sensing → signed RuField `FieldEvent`s.** A new v2 workspace member (the *single coupling point* between RuView and the standalone RuField MFS spec, ADR-262 §5.4) that **path-deps** the `vendor/rufield` submodule crates (`rufield-core`/`-provenance`/`-privacy`/`-fusion` — pure-Rust, `--no-default-features`-buildable: serde/sha2/ed25519/toml only, no tch/openblas/ndarray/candle) and **no** RuView internal crate. The bridge takes owned primitives — `SensingSnapshot` mirrors the `/ws/sensing` `SensingUpdate` (features + classification + signal_field) joined with the `TrustedOutput` trust state (`trust_class`/`demoted`/`identity_bound`) — and `snapshot_to_field_event()` emits one **signed** `FieldEvent` (`Modality::WifiCsi`, axis `[Frequency]`): a real `FieldTensor` from the feature scalars with the real `timestamp_ns`; an `Observation` whose `range_m`/`motion_vector`/`space_cell` are derived from the strongest **signal-field peak** when present (else `None` — coordinates are **never fabricated**, per the `field_localize` caveat) and `confidence` from the classification; a real `ProvenanceRef` (sha256 over the tensor bytes, `synthetic=false`) **ed25519-signed** so `rufield_provenance::is_fusable` passes. **The §3.3 privacy mapping is the critical correctness item**, implemented as `map_privacy()` mapping RuView's class onto RuField P0–P5 **by information content, NEVER by byte value** and **fail-closed**: RuView `Derived` (byte `1`, which sorts *below* `Anonymous` byte `2`) carries an identity embedding → maps to **P4** (or **P5** if identity-bound), **never P1** (the single most dangerous mapping mistake); `Raw → P0`, `Anonymous → P2`, `Restricted → P2`; a governed-engine `demoted` cycle floors the egress class to ≥ P2 with raw suppressed. **P1 acceptance gates (15 tests / 0 failed — 5 unit + 9 integration + 1 doc):** round-trip (`SensingSnapshot → FieldEvent →` serde `→` equal), `is_fusable` (verified ed25519 receipt), `RuFieldFusion::ingest` accept + `infer()` runs, **privacy-safety** (`gate_privacy_safety_derived_never_maps_to_low_privacy` — `Derived → P4/P5`, never P1; a table test over every RuView class; fail-closed demotion), and determinism (same snapshot + same signer seed → byte-identical event). **Honest scope:** this is **P1 plumbing** — a tested conversion + a safe privacy mapping. It is **not** wired into the live server (that is P3) and makes **no accuracy claim** (RuField v0.1 is synthetic; RuView's single-link CSI carries its own caveats). CI: the `rust-tests` workflow checkout gains `submodules: recursive` so the path-deps resolve. Python deterministic proof unchanged (off the signal proof path). +- **ADR-262 (Proposed): RuField MFS ↔ RuView integration — a live `SensingServerAdapter`, a privacy/provenance bridge, MAPPED not papered-over.** Researched integration design for wiring RuField into RuView. Recommends: a thin **`wifi-densepose-rufield` bridge crate** (anti-corruption layer, path-deps on the `vendor/rufield` submodule — the `vendor/rvcsi` pattern, since rufield crates are unpublished); a **live `SensingServerAdapter`** that taps the real `SensingUpdate` emit site joined with `TrustedOutput` trust state and emits one signed `FieldEvent`/cycle (the file-based `CsiReplayAdapter` stays for offline replay); **vertical fusion composition** (ruvsense fuses *within* WiFi → one `wifi_csi` event → rufield-fusion graph fuses *across* modalities above it); and **one canonical privacy/provenance model** (RuView `effective_class` is source-of-truth, mapped to RuField P0–P5 at egress; reuse the existing `cog-ha-matter` SHA-256+Ed25519 chain for the `ProvenanceReceipt`). **Key honest finding:** RuView has **two privacy enums + three witness mechanisms across two hash algorithms** that do not map 1:1 onto P0–P5, and a real trap — RuView's `Derived` privacy byte (`1`) sorts *below* `Anonymous` (`2`) yet carries identity embeddings, so the bridge must map by **information content** (`Derived → P4/P5`), never by byte value, or it would leak identity as low-privacy P1. 4 independently-shippable phases, each with a test gate (round-trip / `is_fusable` / privacy-monotonicity / ed25519-verify). Honest scope: this is **plumbing architecture, not accuracy** — RuField v0.1 is synthetic and RuView's only real-CSI path is unlabeled replay; the ADR claims only architecture, gated by round-trip/monotonicity/signature tests. +- **RuField `CsiReplayAdapter` — first real (non-synthetic) WiFi-CSI adapter (ADR-260 §17).** RuField now ingests **real captured WiFi CSI** instead of only the synthetic simulator. New `rufield-adapters::csi_replay` parses RuView's `.csi.jsonl` recording format (`{timestamp, subcarriers[]}`), normalizes each frame to a `FieldTensor` (`WifiCsi`, real amplitudes + real `timestamp_ns`), establishes a per-subcarrier Welford **empty-room baseline** via `calibrate()`, derives a **physically-grounded CSI-variance motion/presence proxy** (normalized MAD vs baseline → P2 motion/presence, else P1), and emits `FieldEvent`s with a **real sha256 + ed25519 provenance receipt** (`synthetic=false`). **Measured on 199 real captured frames:** 184 presence-proxy / 69 motion-proxy → fed through `RuFieldFusion` → **182 fused inferences (115 breathing, 67 person_present) from real signal.** 12 tests (9 unit + 3 integration over real-CSI fixtures), deterministic (byte-identical stream per file). **Honest caveats (stated everywhere):** it's **replay from file, not live hardware**; recordings are **unlabeled**, so the motion/presence output is a **proxy, NOT validated accuracy** (no pose, no accuracy numbers); live streaming + labeled validation remain roadmap; mmWave/thermal stay synthetic. The win is "RuField ingests real WiFi CSI and produces fused events from it." [`ruvnet/rufield`](https://github.com/ruvnet/rufield) `crates/rufield-adapters`; `vendor/rufield` submodule bumped. +- **RuField `rufield-viewer` web dashboard — completes ADR-260 §27.9 (all §27 criteria 1–10 now PASS).** A read-only Axum + vanilla-JS dashboard (no build step — `cargo run -p rufield-viewer`) that streams the deterministic SyntheticSim→fusion camera-free room-intelligence demo: live room-state inferences with confidence, a scrolling event log where every event carries its modality + a colour-coded **P0–P5 privacy badge**, the fusion graph (supporting=green / contradicting=red per inference), and a click-to-open **provenance-receipt modal** (sha256 + ed25519 signer + verified ✓ / fusable ✓) — behind a permanent, undismissable `SYNTHETIC — simulated sensors, no hardware` banner. Endpoints `/` · `/app.js` · `/health` · `/api/run` (full deterministic JSON) · `/events` (SSE). 12 new tests. Honest scope: a read-only SYNTHETIC demo viewer, **not** a device-management console — fleet/real-adapter management is a separate later milestone. Lives in [`ruvnet/rufield`](https://github.com/ruvnet/rufield) (`crates/rufield-viewer`, repo now 7 crates / 72 tests); `vendor/rufield` submodule bumped to include it. +- **ADR-261: RuVector graph-ANN index — a real HNSW baseline + a SymphonyQG-style quantized variant, MEASURED (honest negative).** Closes the [ADR-156 §5 #1](docs/adr/ADR-156-ruvector-fusion-beyond-sota.md) gap: the SymphonyQG (SIGMOD 2025) **3.5–17× QPS-over-HNSW** claim was CLAIMED-only because **no HNSW baseline existed to compare against**. This adds one. New pure-Rust, `--no-default-features`-buildable modules in `wifi-densepose-ruvector`: `hnsw.rs` (a correct float HNSW — Malkov & Yashunin: multi-layer NSW graph, `ef_construction`/`ef_search`, Algorithm-4 neighbour selection, **seeded-deterministic** level assignment via SplitMix64, L2 + cosine, full degenerate-case guards), `hnsw_quantized.rs` (the SymphonyQG-style variant — the **same** graph traversed by a cheap **1-bit Hamming** score over the RaBitQ Pass-2 rotated sign code, then **exact-float rerank**), `ann_measure.rs` + `benches/ann_bench.rs` (one shared deterministic planted-cluster fixture; the `ann_bench_report` test is the source of truth). **MEASURED (dim=128, N=10k, K=10, `--release`):** float HNSW = **~25× QPS over linear scan at recall ≥0.99** (the baseline this gap needed; recall@10 correctness gate ≥0.95 holds, L2 + cosine). **Honest negative:** the 1-bit quantized traversal is **too coarse to beat float HNSW at equal recall at this scale** — its best recall is **0.738**, never reaching the ≥0.90 equal-recall point, so there is **no QPS win** over float HNSW; the 3.5–17× is **not reproduced** by our 1-bit construction here. The recall gate also **caught a real index-out-of-bounds bug** in the insert path (disclosed in ADR-261 §4). Caveat: this is **our** HNSW + **our** 1-bit quant, not SymphonyQG's exact system — it tests the *direction* of the claim, with the expected crossover at large N + a multi-bit traversal code. **We did not tune to manufacture a speedup.** +20 tests (ruvector lib 131→151, 0 failed). ADR-156 §5 #1 / §8 backlog: CLAIMED → **MEASURED-direction-tested**. Python deterministic proof unchanged (off the signal proof path). +- **ADR-261 Milestone-2: multi-bit quantized HNSW traversal + large-N scaling study — MEASURED (honest negative).** Extends ADR-261's quantized index from 1-bit to **`b`-bit-per-dimension** (`b ∈ {1,2,4}`, 16/32/64 B/node) over the Pass-2 rotated coordinates, and runs a deterministic scaling study (N ∈ {10k, 100k, 250k}) to test M1's *prediction* of a large-N crossover. **Result: no crossover at any measured (N, b), and the trend refutes the prediction.** At N=10k more bits lift the equal-recall QPS ratio (0.19×→0.46×→0.48×) and let b≥2 reach the 0.90 recall bar 1-bit missed — but quant stays slower than float HNSW at equal recall; at N=100k/250k quant recall *collapses* (b=4: 1.000→0.788→0.624, never ≥0.90) while float holds ≥0.92 (denser graph → low-bit codes can't separate near-neighbours, beam goes off-path faster than the float-distance saving repays). Caveat: our HNSW + our per-node multi-bit code, not SymphonyQG's RaBitQ-fused graph — refutes the *direction* at ≤250k, not their million-scale numbers. ruvector lib **151→156** (+5 tests; `scaling_report` `#[ignore]` produced the table). A published negative with the mechanism explained. ADR-261 §11. +- **ADR-260: RuField MFS — the open specification for camera-free multimodal field sensing.** A common event / tensor / calibration / privacy / provenance model that sits *above* WiFi CSI/CIR/BFLD, UWB, BLE Channel Sounding, mmWave radar, ultrasound, subsonic, infrared, and future quantum sensors (each modality emits a normalized `FieldEvent` → `FieldTensor` → `FusionGraph` → `PrivacyClass` → `ProvenanceReceipt`). Published as a **standalone repo** [`ruvnet/rufield`](https://github.com/ruvnet/rufield) and vendored here as the `vendor/rufield` submodule (the `vendor/rvcsi` pattern — not a `v2/` workspace member). The v0.1 reference stack is a self-contained 6-crate Rust workspace (`rufield-core`, `-provenance` [sha256 + ed25519], `-privacy` [P0–P5 guard], `-adapters` [deterministic `SyntheticSim` across wifi_csi/mmwave_radar/infrared_thermal], `-fusion` [graph + TOML weighted-Bayes rules → 7 room-state inferences], `-bench` [deterministic runner + the §31 acceptance test]). **60 tests / 0 failed, clippy-clean.** §27 acceptance criteria 1–8 and 10 PASS; the live dashboard (9) is deferred. **All benchmark metrics are SYNTHETIC** (scored against the simulator's own ground truth — presence/breathing/bed_exit/room_transition F1 = 1.000, nocturnal_scratch 0.923 reported honestly, p95 latency ~0.01 ms, provenance coverage 100%, 0 privacy violations) — they prove the pipeline recovers known truth, **not** field accuracy; real hardware adapters (ESP32 CSI, mmWave, thermal IR) are a documented roadmap item, none validated in v0.1. The Python deterministic proof is unchanged (rufield is off the signal-processing proof path). + +### Security +- **`homecore-assist` voice/intent pipeline security review — one real unbounded-utterance DoS fixed (fail-closed length bound), pinned by fails-on-old tests; command-injection / ReDoS / NaN-poisoning / intent-confusion dimensions confirmed clean with evidence (ADR-133).** Beyond-SOTA review of the HA-compat Assist pipeline (utterance → recognizer → intent → handler → action, plus the `RufloRunner`) — the untrusted-input → action path, un-covered by the ADR-154–159 sweep. **One real finding fixed.** **HC-ASSIST-01 (unbounded-utterance DoS, LOW):** both `RegexIntentRecognizer::recognize` and the semantic `recognize_scored` accepted utterances of unbounded length from untrusted callers (voice transcripts / the WebSocket `assist` command) and ran `to_lowercase()` (a full clone) + a per-registered-pattern scan (and, in the semantic path, full tokenisation + feature-hash embedding) before any bound — an allocation/CPU amplification on attacker-controlled input. The `regex` crate is **linear-time** (no catastrophic backtracking), so this was a throughput/memory DoS, not a hang. **Fixed** by a named `MAX_UTTERANCE_BYTES = 4096` (far above any real spoken command) checked at both recognizer boundaries **before** any allocation/scan; an over-length utterance **fails closed** to `Ok(None)` (no intent, no action), identical to an unrecognised phrase, so it can never be coerced into firing a handler. Legitimate commands unaffected. Pinned by `over_length_utterance_fails_closed` (an over-length utterance that *contains* a valid command resolves to `None` — would have matched on old code) and `over_length_utterance_fails_closed_semantic`. **Dimensions confirmed clean (with evidence, no invented issues):** (1) **command/argument injection** — there is **no subprocess surface**: the `RufloRunner` has exactly two impls, `NoopRunner` (no process) and `LocalRunner` (runs the local recognizer, no process); no `std::process`/`tokio::process`/`Command`/`.spawn()` on any process exists in the crate (`spawn` is a `started: bool` lifecycle flag), and `RufloRunnerOpts.{script_path,env}` are inert data **never consumed** — the live `node ruflo-agent.js` runner is genuinely data-gated/future per the doc-comments. Additionally the `entity_id` capture class `[a-z_][a-z0-9_ .]*` **excludes every shell/SQL metacharacter**, so even when an injection-shaped utterance resolves (the regex is not exact-anchored) the captured slot is a clean token — sanitisation by construction (pinned by `shell_metachars_never_survive_into_a_resolved_slot`, `runner_opts_are_inert_no_process_spawned`, `pipeline_injection_shaped_utterance_carries_no_metachars_to_service`). (2) **ReDoS** — `regex 1.12.3` (no `fancy-regex` in the tree) is a linear-time finite automaton; a classic `(a+)+$` shape on adversarial input completes in bounded time (`pathological_backtracking_pattern_completes_in_bounded_time`). (3) **NaN-poisoning** — embeddings are **structurally finite** (FNV feature-hash + guarded L2 normalise, no external float input, no unguarded division), so a crafted utterance cannot inject NaN/Inf into the cosine k-NN; cosine vs the zero vector is a finite `0.0`; empty-index `max_by` returns `None` (no panic); the NaN-safe `partial_cmp().unwrap_or(Equal)` is already in place (`embeddings_are_structurally_finite`, `cosine_with_zero_vector_is_finite_not_nan`, `empty_utterance_against_empty_index_no_panic_no_match`). (4) **intent confusion / fail-closed** — an unrecognised utterance returns `not_understood()` (no service call), a recognised intent with no registered handler also returns `not_understood()`, semantic below-threshold/empty-index falls back to regex; no default high-privilege intent, no fail-open (`pipeline_injection_shaped_utterance_fires_no_handler` evidence + existing pipeline tests). (5) **panic-on-input** — no `unwrap`/`expect`/index reachable from a crafted utterance (the one `exemplars[id]` index uses an `id` from `enumerate()` over the append-only Vec). `cargo test -p homecore-assist --no-default-features`: **29→36 passed, 0 failed** (+7); default/`semantic`: **39→48, 0 failed** (+9). Workspace green; Python deterministic proof unchanged (homecore-assist is off the signal proof path). Review notes appended to ADR-133. +- **`homecore-automation` security review — two real DoS findings fixed (template unbounded-expansion + delay panic-on-config), each pinned by a fails-on-old test; condition-bypass / fail-closed / action-authz dimensions confirmed clean (ADR-129 §8a).** Beyond-SOTA review of the HA-compat automation engine (the execution/eval surface: triggers → conditions → actions, with user-config Jinja2 templates), un-covered by the ADR-154–159 sweep. **HC-SEC-01 (template DoS, HIGH):** a `template:` condition / `value_template` is user config and was rendered with MiniJinja's defaults — **no instruction budget, no output cap**. A single nested-loop condition rendered a **100 MB string in ~11 s on one render call** (measured) — the bfld-class unbounded expansion (MiniJinja's per-call `range()` 10k cap does **not** stop nesting). **Fixed** by enabling MiniJinja's `fuel` feature + `set_fuel(Some(1_000_000))` (the attack now fails fast ~90 ms with "engine ran out of fuel") and a 64 KiB source-length cap; legitimate templates unaffected. **HC-SEC-02 (panic-on-config DoS, MEDIUM):** `Action::Delay`/`WaitForTrigger` fed the user float straight into `Duration::from_secs_f64`, which **panics** on negative/NaN/inf/overflow — all reachable from a crafted or typo'd YAML (`delay: {seconds: -1}`, `.nan`, `.inf`, `1e308`), aborting the spawned run task (measured panic). **Fixed** by a `safe_duration_from_secs` guard that saturates (NaN/±inf/negative → `0`, matching HA's lenient "non-positive delay = no delay"; huge → clamped to ~100 yr). **Dimensions probed clean (evidence in ADR-129 §8a):** condition eval is **fail-closed** (template-render error → `false`; un-parseable `choose` branch condition → branch skipped, never silently passing); run-modes are **bounded** (Single/Restart/Queued/`max:N` — a self-triggering automation does not livelock, ADR-162 tests); templates are **read-only sandboxed** (no service-call/state-set global exposed to template scope, so a template cannot escalate to an action); no `unwrap`/`expect`/index panic reachable from a crafted config in the eval/exec path beyond the fixed `from_secs_f64`. Fails-on-old verified by reverting each fix in isolation (delay tests panic; template nested-loop test runs unbounded >60 s; oversized-source test fails). `cargo test -p homecore-automation --no-default-features`: **40 → 54 passed, 0 failed** (+14: 4 template-DoS, 1 no-regression render, 5 delay/wait + safe-duration unit). Workspace green; Python deterministic proof unchanged (homecore-automation is off the signal proof path). +- **`cog-ha-matter` witness/manifest crypto review — engine-class signed-digest collision confirmed ABSENT (length-prefixing already correct); domain-separation tag ADDED + `verify_strict` HARDENED; key-handling & verify-before-trust confirmed clean (ADR-116 §2.2).** Beyond-SOTA crypto+security review of the Cognitum/HA-Matter bridge's SHA-256 + Ed25519 witness chain — the exact signing chain ADR-262 P2 proposes to reuse — un-covered by the ADR-154–159 sweep. **Top-priority check: the sibling `wifi-densepose-engine` bug class (unframed boundary-to-boundary concatenation of operator-influenceable strings into a signed/hashed digest).** Result reported honestly: **that bug class is ABSENT here** — `witness::canonical_bytes` already length-prefixes the two variable-length operator-influenceable fields (`kind_len:u32-be ‖ kind`, `payload_len:u32-be ‖ payload`) over fixed-width `prev_hash[32] ‖ seq:u64-be ‖ ts:u64-be`, an injective encoding (proven pre-existing by `canonical_bytes_length_prefixing_prevents_ambiguity`), and `witness_signing::sign_event`/`verify_signature` sign/verify the **identical** bytes the hash chain commits to (no separate unframed concatenation). The manifest `binary_signature` (Ed25519 over the fixed 64-hex-char `binary_sha256`) is signed **at build time by the Makefile**, not in-crate, and over a single fixed-length value — no in-crate manifest-signing concatenation surface. **Two real hardening gaps fixed, the first pinned by fails-on-old tests:** + - **CHM-WIT-01 (missing domain-separation tag, LOW) — ADDED.** The engine review's prescribed fix is "domain-tag **+** length-prefix"; the length-prefix half was present, the **domain tag was absent**. The witness SHA-256 preimage / Ed25519 message carried no tag distinguishing it from any other signing context that shares key infrastructure — notably the manifest `binary_signature`, the very chain ADR-262 P2 reuses. **Fix:** prepend a versioned, NUL-terminated `WITNESS_DOMAIN_TAG = b"cog-ha-matter/witness-event/v1\x00"` to `canonical_bytes` (the doc-comment already anticipated a leading version migration). Cross-protocol separation now holds: a witness signature can never be replayed as a message for another Ed25519 context. **Witness-bytes change by design** (prior on-disk witness hashes/signatures invalidated, like the engine fix) — verified safe: **no in-repo crate consumes cog-ha-matter's witness bytes/signatures programmatically** (all references are doc-comment mentions; the crate is self-contained, no `use cog_ha_matter::` anywhere). Pinned by `canonical_bytes_is_domain_separated`, `canonical_bytes_starts_with_domain_tag_then_prev_hash`, `witness_preimage_cannot_collide_with_a_bare_manifest_digest` (witness.rs) and `signature_commits_to_domain_tag_not_bare_fields` (witness_signing.rs — a signature over the **un-tagged** field concatenation must NOT verify); the domain-separation guard **FAILED on the reverted un-tagged encoding** ("canonical message is not domain-separated"). + - **CHM-WIT-02 (permissive Ed25519 verification, LOW) — HARDENED to `verify_strict`.** For a tamper-evident **audit** chain the signature is the attestation, so `verify_signature` now uses `VerifyingKey::verify_strict` (rejects non-canonical encodings + small-order public keys per RFC 8032) instead of the permissive `Verifier::verify` — giving auditors the "one canonical signature per event" property they rely on when comparing/deduplicating signed records. Not a forgery fix (the public key is caller-pinned, never parsed from the event), reported at true LOW severity. Guarded by `verify_uses_strict_path_and_pins_caller_key`. + - **Dimensions confirmed clean (with evidence, no invented issues):** (1) **verify-before-trust + key-pinning** — `verify_signature` takes the verifying key as a **caller-supplied parameter** (the Seed's known key), never reads a key from the event/manifest, so a forged event carrying its own key cannot self-attest; `WitnessChain::read_jsonl` re-derives and re-checks every `this_hash` on load (tampered bundle → `HashMismatch`) and runs a chain-level `verify()` catching reordered/spliced events (existing `verify_rejects_*`, `jsonl_parser_rejects_tampered_payload`, `read_jsonl_chain_verify_catches_reordered_events`). (2) **key handling** — the crate **never generates, stores, logs, or serializes** a signing key: `sign_event` takes `&SigningKey` by reference, the manifest struct has no key field, and the only key material in-crate is the **test-only** fixed seed (clearly documented "DO NOT use in production"); production keys come from the Seed's secure key store (out of scope, ADR-116 §key-management). No hardcoded/default/predictable production key, no key in the manifest, no world-readable key path (the crate does no key file I/O). (3) **determinism/canonicalization** — `canonical_bytes` is pure positional bytes (no HashMap iteration, no float formatting); Ed25519 is deterministic (pinned by `signature_is_deterministic_for_same_event_and_key`); the JSONL wire form is hand-rolled with **alphabetically-locked** field order (`jsonl_field_order_is_alphabetical_for_byte_stability`) and the mdns TXT records are `sort()`-ed for byte-stable advertisement — no iteration-order or float-format nondeterminism feeds any hash/signature. (4) **fail-closed parsing / DoS** — `from_jsonl_line`/`from_hex`/`hex_decode` return structured errors (never panic) on wrong length, non-hex, missing field, odd-length payload, or hash mismatch (`jsonl_parser_rejects_non_hex_hash`, `hex_decode_rejects_odd_length`, …); `main.rs` reads no untrusted files/paths (clap args only; `--print-manifest` emits a static template) — no path/injection surface. (5) **de-magic** — the witness/signing byte layout is already expressed as named widths; no bare security-relevant literals worth extracting beyond the new named `WITNESS_DOMAIN_TAG`. `cog-ha-matter --no-default-features`: **64→68 tests**, 0 failed (+3 domain-tag witness, +1 signing-layer domain-commit, +1 strict-verify key-pin; one pre-existing test renamed to assert the tag). Workspace green; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — cog-ha-matter is off the signal proof path). Review notes appended to ADR-116 §2.2. +- **`homecore-api` (HA-wire-compat REST + WebSocket) beyond-SOTA security review — `GET /api/` auth-gate gap FIXED + WS event-stream lag-DoS robustness FIXED; auth/traversal/injection/info-leak dimensions confirmed clean (ADR-161 / ADR-130).** Network-facing review of the HA-wire-compat API layer (remote attack surface), not covered by the ADR-154–159 sweep — same scrutiny the sibling `wifi-densepose-engine` and `-bfld` reviews got. **Two real bugs fixed, each pinned by a fails-on-old test.** + - **HC-API-AUTH-01 (auth-gate gap, LOW) — `GET /api/` was unauthenticated; FIXED.** Every sibling REST route (`/api/config`, `/api/states`, `/api/services`, …) calls `BearerAuth::from_headers` first, but `rest::api_root` took no headers and unconditionally returned `200 {"message":"API running."}`. HA's `APIStatusView` inherits `requires_auth = True`, so an unauthenticated/wrong-token request to `/api/` must be **401** — HA clients use this status route as a token-validation probe, and a 200 both told a bad-token client its token was good and let an unauthenticated party confirm a live endpoint. Severity is LOW (the body is a static string — no entity/state data leaks), reported at true severity, not inflated. **Fix:** `api_root` now validates the bearer like its siblings. Pinned by `api_root_rejects_missing_bearer` + `api_root_rejects_wrong_bearer` (both 200→assert-401 on old code) and guarded by `api_root_accepts_correct_bearer`. + - **HC-WS-LAG-01 (DoS-adjacent silent failure, LOW) — `subscribe_events` killed the event stream on a broadcast lag; FIXED.** The per-subscription task matched `Err(_) => break` on both `broadcast::Receiver::recv()` arms, but `Lagged(n)` (a slow consumer falling >4,096 events — `EVENT_CHANNEL_CAPACITY` — behind) is **recoverable**: the bus doc itself says "Lagged receivers must re-sync", and HA's WS contract keeps the subscription alive across a lag. The old code treated the first lag as fatal, so after an event burst the client's stream went **permanently silent** with no error frame — a self-inflicted event-delivery DoS under load. **Fix:** `Lagged(_) => continue` (skip the dropped window, re-sync), `Closed => break`, on both the system and domain arms. Pinned by `subscription_survives_broadcast_lag` (subscribes, floods 6,000 filtered events past the 4,096 capacity to force a `Lagged`, then asserts a subsequent subscribed event is still delivered — 5s-timeout panic on old code). + - **Dimensions confirmed clean (with evidence, no invented issues):** (1) **AuthN/AuthZ** — all 7 other REST handlers (`get_config`/`get_states`/`get_state`/`set_state`/`delete_state`/`get_services`/`call_service`) gate on `BearerAuth::from_headers` → `LongLivedTokenStore::is_valid` before any work; the WS handshake validates the `auth` token against the **same** store before entering the command loop and the privileged commands are unreachable pre-`auth_ok` (HC-WS-01, already fixed). Token compare is a `HashSet::contains` (content-independent timing, not the byte-`==` oracle ADR-157 §B4 fixed in hardware) — no timing-oracle finding. No route skips the gate, no result-ignored check, no default/empty token accepted (`is_valid` rejects empty internally; `from_env` is non-dev). (2) **Path traversal** — **no route maps user input to a filesystem path** (state lives in an in-memory `DashMap`); `:entity_id` is funneled through `EntityId::parse`, a strict `[a-z0-9_]+\.[a-z0-9_]+` ASCII allowlist that rejects `..`, `/`, `\`, and absolute paths. No traversal surface exists. (3) **Injection** — no SQL, no shell/subprocess, no `format!`-into-response; `call_service`/`set_state` bodies are typed `serde_json::Value` passed to the in-process service registry (matches HA). (4) **Info-leak** — `ApiError` maps to fixed status + a `{message}` derived only from typed variants; `call_service`'s `ServiceError::HandlerFailed(String)` is integration-controlled (mirrors HA surfacing the handler error), not framework internals/paths/stack-traces (no ADR-080-class leak). (5) **CORS** is an explicit allowlist (`allow_credentials(false)`, HC-05 already fixed), not `permissive()`. (6) **De-magic** — no bare security-relevant literals in this crate worth extracting (`EVENT_CHANNEL_CAPACITY` already named in `homecore`; CORS dev-default ports are documented). `homecore-api --no-default-features`: **25→29 tests**, 0 failed (+2 api-root auth, +1 api-root accept-guard, +1 WS lag-survival); workspace green; Python deterministic proof unchanged (homecore-api is off the signal proof path). Review notes appended to ADR-161. +- **`wifi-densepose-calibration` per-room calibration review — NaN-poisoning fail-closed gap FIXED + file/path & receipt surfaces confirmed clean (ADR-151).** Beyond-SOTA correctness+security review of the ADR-151 `baseline → enroll → extract → train → bank` pipeline (the appliance-deployed per-room specialist core), un-covered by the ADR-154–159 sweep. **One real numerical-robustness bug fixed.** `Features::from_series` — the live-inference *and* training feature path — computed `mean`/`variance`/`motion` over the raw scalar series with **no non-finite guard**, so a single `NaN`/`±inf` sample (a corrupt CSI frame) produced `mean=NaN, variance=NaN` and an all-`NaN` prototype embedding. Baked into a persisted `PresenceSpecialist::threshold`/`empty_mean` at train time, that `NaN` **silently disabled presence detection** for the life of the bank (every `f.variance > NaN` and `|mean − NaN|` comparison is false → presence always reads *absent*, confidence 0), with **no error raised** — the exact "produce NaN that poisons a specialist / silently accept garbage" failure, and an asymmetry vs the meticulously NaN-guarded `geometry_embedding.rs`. **Fix at the production boundary:** filter non-finite samples before any statistic (a corrupt frame counts as no frame); a wholly-non-finite series degrades to the new `Features::ZERO`, exactly like the empty series. **Value-identical for all-finite input** — `full_loop.rs` and every existing `extract` test pass unchanged. Pinned by two fails-on-old tests (`non_finite_samples_do_not_poison_features`, `all_non_finite_series_is_zero`, both FAILED pre-fix). **Dimensions confirmed clean (with evidence, no invented issues):** (1) **file/path handling** — the crate does **zero** file/path I/O (no `std::fs`/`Path`/`File`/`read`/`write` anywhere in `src/`; only in-memory `serde_json`), so path-traversal / unbounded-read / artifact-path concerns do not exist at the crate boundary — they live in the `wifi-densepose-cli` consumer (`room.rs`), out of this crate's scope; (2) **untrusted-load** — `SpecialistBank::from_json` parse-validates shape via serde (malformed → `CalibrationError::Serde`), and per ADR-151 invariant (B) banks are local-first, never network-received; (3) **receipt/hash integrity** — the crate emits **no** hash/receipt/witness/signature (no `CalibrationReceipt` analogue), so the engine's unframed-concatenation bug class is structurally absent — nothing to mis-frame; (4) **other numerical paths already robust** — `geometry_embedding.rs` sanitizes every input + sweeps to finite (verified by its `adversarial_inputs_never_produce_nan` test); presence/restlessness/anomaly divisions are all `.max(1e-3)`-guarded; `autocorr_dominant` guards `r0 ≤ 1e-6`, `n < 16`, empty bands; `SpecialistBank::train` rejects empty anchors; anomaly requires ≥2 anchors. De-magicked the bare specialist threshold literals (breathing 0.25 / heartbeat 0.3 default min-scores, anomaly 2.0× spread / >0.5 label cutoff) into named documented consts, value-identical, pinned by `default_min_score_constants_match_prior_literals` + `anomaly_constants_match_prior_literals`. `wifi-densepose-calibration --no-default-features`: **58→62 unit tests** (+2 NaN fail-closed, +2 de-magic pins) + 1 full-loop integration, 0 failed.

Review notes appended to ADR-151 §6. +- **`wifi-densepose-engine` governed-trust review — witness domain-separation gap FIXED + privacy monotonicity confirmed clean (ADR-137 / ADR-141 / ADR-032).** Beyond-SOTA correctness+security review of the security-critical composition root (the cycle enforcing RuView's privacy guarantees), not covered by the ADR-154–159 sweep. **One real witness-integrity bug fixed.** `witness_of` concatenated `model_version`, `calibration_version`, and `privacy_decision` boundary-to-boundary and left the variable-length evidence list without a count, so a string straddling a field boundary collided with a *different* trust decision — e.g. a per-room adapter id (ADR-150 §3.4, operator-influenceable) absorbing the leading bytes of the calibration epoch (`model="…cal:00a"`,`cal="b"`) yields the same witness as `model="…"`,`cal="cal:00ab"`. Two distinct privacy-relevant input tuples → one witness defeats the ADR-137 §2.7 "any privacy-relevant delta → different witness" tamper/drift audit. **Fix:** domain-tag the BLAKE3 hash (`ruview.engine.witness.v1`), write an explicit evidence count, and **length-prefix every field** (8-byte LE length ‖ bytes) — unambiguous framing regardless of contents. Witness-layout change by design (prior witness bytes invalidated); downstream consumers (`engine_bridge`, rufield) assert only witness *relationships* (`assert_ne`/`assert_eq` across runs), never absolute bytes, so nothing breaks. Pinned by two fails-on-old tests: `witness_distinguishes_model_calibration_boundary`, `witness_distinguishes_evidence_model_boundary`. **Dimensions confirmed clean (with evidence, no invented issues):** (1) **privacy monotonicity** — `effective_class` is recomputed each cycle from the active mode's floor with at most a single-step `demote_one` (clamped at `Restricted`), no cross-cycle state, proven over **all 5 modes** by `forced_contradiction_never_relaxes_class` (forced contradiction only ever raises the class byte; clean cycle == base); (2) **fail-closed** — empty cycle errors with no degenerate output (`empty_cycle_fails_closed`), single-node boundary characterized (`single_node_cycle_is_well_formed`), NaN coupling → `max(0.0)`→absent edge→at-risk (more restrictive); (3) **witness determinism** — no HashMap iteration / float formatting feeds the hash; (4) **mesh_guard** (ADR-032) — partition-risk → demotion path verified, thresholds already named documented fields. De-magicked the engine-construction literals (coherence accept gate, ADR-143 SLAM discovery + static-anchor thresholds) into named documented consts, value-identical, pinned by `engine_constants_match_prior_values`. `wifi-densepose-engine --no-default-features`: **27→33 tests**, 0 failed (+2 witness, +1 monotonicity property, +2 fail-closed boundary, +1 de-magic pin). Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — the engine is off the signal proof path). Review notes appended to ADR-137 (witness) and ADR-141 (monotonicity). +- **ADR-141 BFLD privacy-bypass closed — `process_to_frame` now routes the payload through `PrivacyGate` (`wifi-densepose-bfld`).** `BfldPipeline::process_to_frame` stamped the emitted `BfldFrame` header with the active `PrivacyClass` but serialized the caller-supplied `BfldPayload` **unchanged** via `BfldFrame::from_payload`. A frame labeled `Anonymous`(2) or `Restricted`(3) therefore carried the full identity-leaky `compressed_angle_matrix` (the beamforming-angle identity surface) + amplitude/phase proxies + `csi_delta` — exactly the sections `PrivacyGate::demote` is documented and tested (`privacy_gate_demote.rs`) to strip at those classes. Because a `NetworkSink` accepts class ≥ `Derived`(1), such a frame would publish the identity surface across the node boundary despite its restrictive class byte; the class byte lied about payload content. **Fix:** after building the frame at the active class, apply `PrivacyGate::demote` to the same class — a no-op class transition that strips the sections that class forbids (research classes `Raw`/`Derived` keep the full payload). Pinned by three fails-on-old tests in `pipeline_to_frame.rs` (`…_at_anonymous_strips_identity_leaky_sections`, `…_in_privacy_mode_strips_amplitude_and_phase` — both FAILED pre-fix; `…_at_derived_preserves_full_payload` guards against over-stripping). Grade: privacy-bypass FIXED + regression-pinned. +- **ADR-157 Milestone-1 B4 - constant-time HMAC sync-beacon tag compare (`wifi-densepose-hardware`).** `AuthenticatedBeacon::verify` compared the 8-byte HMAC-SHA256 tag with `self.hmac_tag == expected`, which short-circuits on the first differing byte and leaks, through verification latency, how many leading bytes an attacker's forged tag matched - a byte-by-byte tag-recovery oracle (~256*N trials instead of 256^N). Replaced with a hand-rolled branch-free `constant_time_tag_eq` (XOR-accumulate every byte difference into a single `u8`, no early exit, `#[inline(never)]` + `core::hint::black_box` to stop the optimizer reintroducing a short-circuit or a non-constant-time `memcmp`). **No new dependency** - ADR-157 had deferred this only to avoid adding the `subtle` crate; a fixed 8-byte compare needs none. Grade MEASURED (constant-time *construction*; micro-timing on a noisy host is a smoke check only, gated `#[ignore]`). Pinned by `tag_compare_is_constant_time_shape` (equal/first-differ/last-differ/all-differ/length-mismatch + an end-to-end `verify()` last-byte tamper), proven to fail on a last-byte-skipping constant-time bug. ADR-157 §8 B4 -> RESOLVED. +- **ADR-080 open HIGH findings closed on the Rust `wifi-densepose-sensing-server` boundary (ADR-164 G11).** The QE sweep's three HIGH findings — XFF-spoofing bypass, leaked stack traces, JWT-in-URL (CWE-598) — were logged against the Python v1 API and never re-verified against the shipped Rust sensing-server; the HOMECORE/M7 sweep (ADR-161) covered `homecore-server`, not this crate. + - **#2 leaked internal errors (the one live exposure) — FIXED.** Six handlers in `main.rs` serialized the internal error `Display` straight into the JSON response body: `edge_registry_endpoint` returned a panicked `spawn_blocking` `JoinError` (`"task … panicked"`) in a `500`, plus the raw upstream error in a `503`; `delete_model`/`delete_recording`/`start_recording` returned `std::io::Error` strings (OS detail / path); `calibration_start`/`calibration_stop` returned the `FieldModel` error chain. New `error_response` module logs the full detail **server-side only** (with a correlation id) and returns a generic body (`{"error":"internal_error","correlation_id":…}`) — no `panicked`, no file paths, no Debug chain. 5 module tests (a leak-substring guard proven to fail on the reverted old body) + the existing handler suite. + - **#1 XFF-spoofing bypass — VERIFIED ABSENT, regression-pinned.** The sensing-server has no XFF-trusting control to bypass: there is no IP-based rate-limiter or IP-allowlist, and neither `bearer_auth` (token-only) nor `host_validation` (Host-header only) reads `X-Forwarded-For`/`X-Forwarded-Host` (no `forwarded`/`peer_addr`/`client_ip` anywhere in the crate). Added regression tests proving a spoofed `X-Forwarded-For` never flips an auth decision and a spoofed `X-Forwarded-Host` never bypasses the Host allowlist. + - **#3 JWT-in-URL (CWE-598) — VERIFIED ABSENT, regression-pinned.** `require_bearer` reads the token only from the `Authorization` header; the WebSocket handlers take no token query param and the sole `Query` extractor (`EdgeRegistryParams`) is a non-secret `refresh` flag. Added a regression proving `?token=`/`?access_token=` in the URL never authenticates while the header path still does. + +### Fixed +- **`wifi-densepose-geo` numerical-robustness audit — `parse_hgt` degenerate-input panic FIXED + `haversine` antipodal NaN FIXED; pole-singularity & pointcloud NaN-state-poisoning confirmed clean (ADR-154-class sweep).** Targeted numerical-robustness audit of `wifi-densepose-geo` + `wifi-densepose-pointcloud`, hunting the proven non-finite-input-poisons-persistent-state class. **Two real bugs in `geo`, each pinned by a fails-on-old test.** (1) **`terrain.rs::parse_hgt` usize-underflow panic** — `side = sqrt(n_samples)`; for an empty / sub-2x2 buffer `side ≤ 1`, so `1.0 / (side - 1)` underflows `usize` (panic "attempt to subtract with overflow" in debug; wraps to a huge value in release → garbage/inf `cell_size_deg` that then poisons every `ElevationGrid::get` lookup). A truncated SRTM download, a 404 HTML body, or an empty response all reach `parse_hgt` — now `bail!`s with a clear error when `side < 2`. Pinned by `parse_hgt_empty_data_errors_not_panics` (panicked pre-fix) + `parse_hgt_single_sample_errors` (returned inf pre-fix) + a `parse_hgt_minimal_2x2_is_finite` guard. (2) **`coord.rs::haversine` asin-domain → NaN** — for (near-)antipodal points floating rounding can push `h.sqrt()` to `1.0 + ~4e-16`, and `asin(>1)` is NaN, silently breaking every downstream `<`/`>` distance comparison (verified: pair `(-44.4994,-178.95722)→(44.49939999,1.04278001)` yields `h=1.0000000000000004`). Fixed by clamping into `[0,1]` before `asin`. Pinned by `haversine_near_antipodal_is_finite_not_nan` (NaN pre-fix). The ±90° pole-singularity (`cos(lat)=0` division in the ENU transforms) is pinned as no-panic without changing the transform (value-identical for valid inputs). **`wifi-densepose-pointcloud` is confirmed-robust — no bug, no manufactured finding:** the only persistent auto-accumulating state (`occupancy` EMA, vitals) is fed exclusively from the integer-rssi/`sqrt`/`atan2` parser, which can only emit finite values, and the persistent state is provably self-healing even under an adversarial hand-built `CsiFrame` carrying NaN/inf amplitudes+phases (`motion_score=(NaN/100).min(1.0)→1.0`; breathing path `→0→clamp(5,40)→5.0`; tomography EMA uses only integer rssi). Pinned by `nonfinite_frame_does_not_poison_persistent_state` (injects 40 poisoned frames, asserts occupancy/vitals stay finite + the pipeline recovers) and three degenerate-voxel-fusion no-panic tests (empty/single/all-coincident). `wifi-densepose-geo --no-default-features`: 9→15 lib (+6), 8 integration unchanged; `wifi-densepose-pointcloud`: 18→22 (+4); 0 failed; workspace green; Python proof unchanged (`f8e76f21…46f7a`, bit-exact — both crates off the signal proof path). +- **Vitals IIR filters self-heal after a non-finite CSI frame — a single NaN/inf no longer permanently kills breathing & heart-rate extraction (`wifi-densepose-vitals`, safety; ADR-021 / ADR-158 §A1).** The 2nd-order resonator in `breathing::BreathingExtractor::bandpass_filter` and `heartrate::HeartRateExtractor::bandpass_filter` latches each output `y[n]` into the filter state (`y1`/`y2`). A non-finite input — one NaN/inf amplitude residual from a corrupt CSI frame — produced a NaN `output` that was written into the state. The existing `extract()` `is_finite()` guard correctly dropped that single sample from history, **but never sanitized the poisoned filter state**, so every subsequent output stayed NaN, was rejected too, and the sliding-window history *never refilled*: the extractor went silently dead (returning `None` forever) until `reset()`. On the vitals alert path this is a safety-relevant denial of service — one bad frame and breathing **and** heart-rate monitoring stop, with no error surfaced. Fix: when `bandpass_filter` computes a non-finite `output` it now resets the IIR state to default and returns `0.0`, so the resonator recovers on the next clean frame (the `0.0` is still dropped by the caller's finite-check — no spurious sample enters history). Same class as the calibration NaN bug (ADR-154 §3) and the firmware vitals fixes (#998/#996/#987): the prior hardening guarded the *history boundary* but not the *filter-state boundary*. Pinned by `breathing::tests::nan_frame_does_not_permanently_poison_filter`, `breathing::tests::inf_mid_stream_does_not_freeze_history`, and `heartrate::tests::nan_frame_does_not_permanently_poison_filter` (all three FAIL on the pre-fix code, verified by reverting). Also de-magicked the safety-critical HR physiological plausibility band into named `HR_PLAUSIBLE_MIN_BPM`/`HR_PLAUSIBLE_MAX_BPM` consts (value-identical 40/180 BPM, pinned by `plausibility_band_constants_pinned`) and added a fabricated-vital negative (`pure_noise_is_never_reported_valid` — broadband noise never yields a clinically `Valid` HR). `wifi-densepose-vitals --no-default-features`: 55→60 lib tests, 0 failed; workspace green; Python proof unchanged (vitals is off the deterministic proof's signal path). +- **BFLD MQTT `zone_activity` payload now JSON-escapes the zone name (`wifi-densepose-bfld`).** `mqtt_topics::render_events` emitted the zone payload as `format!("\"{zone}\"")` with no escaping, while `ha_discovery.rs` already escapes operator-controlled strings. A zone name containing a `"` or `\` produced malformed/injectable JSON on the Home-Assistant state topic (e.g. zone `a"b` → payload `"a"b"`). Added a `json_string_literal` escaper mirroring `ha_discovery::push_str_field` and applied it to the zone payload — value-identical for normal zone names (`living_room`, …). Pinned by `zone_payload_escapes_json_metacharacters` (FAILED pre-fix; round-trips through `serde_json`); the existing `zone_payload_is_json_string_with_quotes` still passes unchanged. +- **ESP32 vitals: `n_persons` over-counted (reported 4 for one person) + presence flag flickered at close range (#998, #996).** Two firmware logic bugs in `firmware/esp32-csi-node/main/edge_processing.c`, both robustness/logic fixes — **not** validated-accuracy claims (true count/PCK vs labelled ground truth stays hardware/data-gated on the COM9 ESP32-S3). + - **#998 over-count — root cause + fix.** `update_multi_person_vitals()` split the top-K subcarriers into `top_k_count/2` groups and marked **every** group `active` unconditionally, so one body's multipath always reported the full `EDGE_MAX_PERSONS` (=4). New pure, host-testable `count_distinct_persons()` gates each candidate group: (1) **energy gate** — a group's phase variance must be ≥ `EDGE_PERSON_MIN_ENERGY_RATIO` (0.35) × the strongest group's, so weak multipath echoes don't count; (2) **spatial dedup** — groups whose representative subcarriers sit within `EDGE_PERSON_MIN_SC_SEP` (4) of each other are the same body. A `person_count_debounce()` then requires the gated count to hold `EDGE_PERSON_PERSIST_FRAMES` (3) consecutive frames before it's emitted, so a single noisy frame can't promote a phantom. The strongest group always counts (a present body yields ≥1). All thresholds are named, documented constants in `edge_processing.h`. + - **#996 presence flicker — root cause + fix.** Presence was a bare `score > threshold` compare on a noisy `presence_score` (field-observed 2.6–26.7 frame-to-frame for one stationary person), so the boolean chattered at the boundary while the score clearly indicated a person. New pure `presence_flag_update()` is a Schmitt trigger + clear-debounce: assert above `threshold`, **hold** in the dead band down to `threshold × EDGE_PRESENCE_HYST_RATIO` (0.5), and only clear after the score stays below the low threshold for `EDGE_PRESENCE_CLEAR_FRAMES` (5) consecutive frames. The score itself is unchanged (and still emitted at packet offset 20 for consumer-side thresholding). Constants named/documented in `edge_processing.h`. + - **Tests:** `firmware/esp32-csi-node/test/test_vitals_count_presence.c` (host C99, `make run_vitals`) — 13 cases / 22 assertions, all passing under gcc 13 `-Wall -Wextra`. Pins: single-strong-signature + multipath → count==1; two well-separated → count==2; two strong-but-adjacent → 1 (dedup); transient count spike rejected; sustained change accepted; dithering presence trace → stable flag (no flicker); genuine departure → clears within hold window. The named tuning constants are `#include`d from the real header so the test and firmware can't disagree. **Hardware-gated caveat:** these pin the decision *logic*; the exact energy/separation/hysteresis values that best match a real room vs labelled occupancy remain on-device tuning (COM9 ESP32-S3 + ground truth). +- **Observatory 3D figure never animated — `/ws/sensing` omitted per-person `position`/`motion_score`/`pose` (#1050).** The `sensing_update` frame shipped `nodes`/`features`/`classification`/`signal_field` and a `persons[]` carrying only image-space `keypoints`/`bbox`/`zone`; the Observatory's `FigurePool`/`PoseSystem` (and `demo-data.js`'s own contract) animate each figure from `persons[i].position` (room-world `[x,y,z]`), `persons[i].motion_score` (0..100), and `persons[i].pose`, none of which the live stream emitted — so the figure sat static while signal metrics updated. **Honest scope (Case 2 — no calibrated per-person localizer exists):** a single ESP32 link does not produce calibrated room-coordinate localization or per-person skeletal pose, so the fix emits only what is *truthfully derivable*. New `field_localize` module reads the **strongest peak(s)** out of the frame's real `signal_field` grid (already built from measured subcarrier variances × measured motion-band power) and maps the peak cell to Observatory world coordinates with the **exact** `_buildSignalField` transform (`x=(ix−nx/2)·0.6`, `z=(iz−nz/2)·0.5`, `y=0`), so the figure lands on the field hotspot it stands on. `motion_score` is the measured `motion_band_power` passed through (clamped 0..100); `pose` is set **only** from a real aggregate `posture` estimate when one exists, else `None` (never a fabricated skeleton — per-person pose keypoints in room coordinates stay gated on the pose model + ADR-079 paired data). An empty / below-threshold field yields `persons: []` (no phantom person); a present person on a field with no resolvable peak keeps `position=[0,0,0]` (not invented coords) while `motion_score` stays real. `attach_field_positions` runs after the tracker step at all five broadcast sites. **No UI change required** — the Observatory already reads these fields and defaults `pose`→`'standing'` when absent. New `PersonDetection.position`/`motion_score`/`pose` fields added to both the `main.rs`-local and `types.rs` structs. Pinned by 10 tests: `field_localize` peak-extraction/coordinate-mapping/empty-field/separation unit tests + `observatory_persons_field_position_tests` (`sensing_update_emits_persons_with_field_derived_position` feeds a synthetic field with a known peak at cell (15,4) and asserts the emitted `position` = `[3.0, 0, −3.0]` within tolerance; `empty_room_yields_no_phantom_person`; `pose_is_real_when_posture_present_and_absent_otherwise`; `present_but_below_threshold_field_keeps_position_at_origin_not_fabricated`). `wifi-densepose-sensing-server --no-default-features`: bin **441→451**, 0 failed; workspace green; Python proof unchanged (off the deterministic proof path). +- **ADR-155 Milestone-1b — metric-definition unification, the §8 backlog subset (Goals A/B/C).** Closed the two §8 metric-integrity items; every change pinned by a test, graded MEASURED. The audit (Goal A) also surfaced findings the §1 table under-counted — recorded honestly in ADR-155 §8.1, not hidden. Workspace stays green; Python proof unchanged (metrics are not on the deterministic proof's signal path). + - **Goal B — `test_metrics.rs` now validates the production metric, not a reimplementation.** The integration test previously asserted properties of its OWN local `compute_pck`/`compute_oks` (a test that can't catch a canonical-impl bug — both could be wrong the same way). Hoisted the canonical core (`pck_canonical`/`oks_canonical`/`canonical_torso_size`/sigmas/`bounding_box_diagonal`) into a new **un-gated** `metrics_core` module so the single definition is reachable under `cargo test --no-default-features` (the `metrics` module is `tch-backend`-gated); `metrics` re-exports it → still exactly ONE implementation. Rewrote the test to assert the production `pck_canonical`/`oks_canonical` equal **hand-computed** fixtures (`canonical_pck_matches_hand_computed_fixture` = 3/4 correct ⇒ 0.75; hip↔hip normalizer pin; zero-visible⇒0.0; OKS perfect⇒1.0; fake-Gold pin) plus a differential cross-check (`test_kernel_agrees_with_canonical`: an independent raw-threshold kernel must AGREE with canonical where torso==1.0). `wifi-densepose-train --no-default-features`: test_metrics **10→12**, 0 failed. + - **Goal C — divergent live-server PCK/OKS relabelled so they're never conflated with canonical.** Goal C named `training_api.rs:804` (torso-HEIGHT PCK); the audit found that file is an **orphan (not `mod`-declared, does not compile)** and the **real** live `best_pck`/`best_oks` come from `trainer.rs` — a **raw, unnormalized** `pck_at_threshold` and an **`area=1.0` fake-Gold** `oks_map` (both MISSED by ADR-155 §1, both on the claim-inflating side, both serialized as bare "PCK@0.2"/"OKS"). Torso-height/raw math is load-bearing (pixel-space, different scale axis, no `ndarray`/train dep), so the honest fix is **relabel, not force-unify**: `training_api.rs` `compute_pck` → `compute_pck_torso_height` + field/log docs; `trainer.rs` kernels documented raw/fake-Gold; `main.rs` prints `pck_raw@0.2` / `oks_map(area=1.0 proxy)`. No wire-format field or `pub`-fn renames (no silent API break). Pinned by `torso_pck_is_labelled_distinctly_from_canonical` + `pck_at_threshold_is_raw_unnormalized_not_canonical`. `wifi-densepose-sensing-server --no-default-features`: lib **450→451**, 0 failed. True unification onto `pck_canonical`/`oks_canonical` remains a tracked ADR-155 §8 item. +- **Pre-existing `SketchBank::topk` heap inversion returned the FARTHEST sketches (found during ADR-156 §8 Pass-2 work).** The `n > k` partial-sort path in `wifi-densepose-ruvector/src/sketch.rs` used `BinaryHeap>` (a min-heap) but its eviction logic treated the peek as the max, so it kept the k *farthest* sketches and returned them as "nearest." The shipped unit tests only exercised the `n ≤ k` fast path (≤ 3 entries), so the inversion shipped silently in ADR-084. Fixed to a plain max-heap. Pinned by `topk_heap_path_returns_nearest` (farthest-first insertion exposes it) and `tight_clusters_give_high_coverage_with_overfetch` (**measured 0.072 coverage on the old code** — effectively random — vs >0.99 fixed). Every ADR-084 top-K coverage number depends on the fixed path. MEASURED, not a no-op. +- **ADR-154 Milestone-1 — cleared the P1 deferred backlog in `wifi-densepose-signal` (§7.4 #1, #10; partial #9, #13).** Each fix pinned by a regression test that fails on the old behaviour; every claim graded MEASURED / DATA-GATED; no fabricated thresholds. Python proof unchanged (`f8e76f21…46f7a`, bit-exact — the CIR ghost-tap guard is not on the deterministic proof path). + - **#1 (MEASURED metric / DATA-GATED threshold): circular phase variance.** `cir.rs::phase_variance` computed a *linear* sample variance over phase angles that wrap at ±π, so a tightly-clustered set straddling the branch cut reported spuriously HIGH dispersion — false-tripping the `> TAU` ghost-tap **guard** on real, tightly-clustered CIR taps. Replaced with Mardia's **circular variance** V = 1 − R̄, bounded **[0,1]** and invariant to where the cluster sits on the circle. The old TAU-scaled threshold is meaningless on [0,1]; re-derived against a named const `GHOST_TAP_CIRCULAR_VARIANCE_MAX = 0.99` (fires only when R̄ ≤ 0.01 — essentially uniform phase). The **metric is MEASURED**; the **threshold value is DATA-GATED** (a clean single-path ramp also sweeps the circle, so V alone can't separate clean from unsanitized without labelled frames — the default is deliberately conservative, strictly more permissive at the wrap boundary than the buggy linear guard). Fails-on-old: `phase_variance_circular_not_fooled_by_branch_cut` (old linear variance > TAU on wrap-straddling phases while circular V≈0, guard no longer trips) + `phase_variance_circular_is_bounded_and_extremal` (V∈[0,1], V≈0 identical, V≈1 uniform). + - **#10 (MEASURED): Welford n=0/n=1 finiteness guard pinned.** The shared `WelfordStats` (`field_model.rs`) `count < 2` guards keep `variance`/`sample_variance`/`std_dev`/`z_score` finite at the boundaries, but the n=0 case was untested (same family as the §4 divide-by-(n−1) trio). Added `welford_finite_at_n0_and_n1` — finite + documented-sentinel (0.0) at n=0/n=1. Fails-on-old proof: removing the `sample_variance` guard makes the test panic with "attempt to subtract with overflow" at the `(count − 1)` underflow (guard restored). + - **#9, #13 (DATA-GATED): de-magicked thresholds + boundary tests (values UNCHANGED).** Lifted the bare detection literals in `adversarial.rs` (`check`/`check_consistency`: Gini 0.8, energy ratios 2.0/0.1, consistency 0.1·mean, score weights), `coherence.rs::classify_drift` (0.85, 10) and `coherence_gate.rs` defaults (0.85/0.5/200/3.0) into named, documented consts marked EMPIRICAL DEFAULT pending labelled calibration. Added characterization/boundary tests pinning each decision at/just-below/just-above its threshold (`energy_ratio_high_boundary`, `energy_ratio_low_boundary`, `field_model_gini_boundary`, `consistency_active_fraction_boundary`, `classify_drift_*_boundary`, `*_consts_unchanged_from_literals`) so a future labelled-data retune is a visible, tested change. The operating **values were not changed**; the de-magicking + tests are MEASURED, the values stay DATA-GATED. +- **Multistatic fusion guard was too tight for real TDM hardware (#1031).** `MultistaticConfig::default().guard_interval_us` was 5,000 µs (5 ms) with a comment claiming "well within the 50 ms TDMA cycle" — but on a real N-slot TDM schedule node `k` transmits in slot `k`, so two nodes are separated by the *slot offset*, not clock jitter. A real 2-node mesh (slots 0/1) measured an **18,194 µs** spread, so every real frame set exceeded the 5 ms guard and `fuse()` silently fell back to per-node sum/dedup — multistatic fusion never actually ran on hardware. Raised the default hard guard to **60 ms** (a full 50 ms TDMA cycle + 20% jitter headroom, derived from the slot model and documented in the field doc) and the soft guard to **20 ms** (just above the observed 18.2 ms 2-slot spread, so a normal cycle fuses cleanly with no privacy demotion). Added `MultistaticConfig::for_tdm_schedule(total_slots, slot_duration_us)` to derive the guard from a deployment's exact schedule, and a `WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US` env seam in sensing-server. The honest per-node fallback remains for genuinely-mismatched frames — now the exception, not the default. Pinned by `fuse_real_tdm_spread_18194us_fuses_with_default_guard` (fails on the old 5 ms default) + `configurable_guard_rejects_too_large_spread` (guard still rejects a spread beyond one cycle). +- **Published HuggingFace model was unloadable — RVF format mismatch (#894).** The `ProgressiveLoader` rejected the published `ruvnet/wifi-densepose-pretrained` model with the opaque `invalid magic at offset 0: expected 0x52564653 (RVFS), got 0x77455735`, then silently fell back to signal heuristics (the "10 persons for 1" garbage reporters saw). The HF repo ships `model.safetensors`, `model-q{2,4,8}.bin` (magic `0x77455735` = "5WEw"), and `model.rvf.jsonl` — none carry the binary-RVF magic. New `model_format` module **auto-detects** RVFS / safetensors / HF-quant-bin / JSONL by magic+name, returns a **typed actionable** `ModelLoadError` (lists accepted formats + the one-command convert path — never the opaque magic), and **converts** `model.safetensors` / `model.rvf.jsonl` → RVF in-memory so the published full-precision model now loads via `--model`. A `--convert-model --convert-out ` CLI subcommand gives a one-command offline path; the silent heuristics fallback is now a loud, actionable error. **Honest scope:** the converter wires the format/load path (safetensors F32 tensors → RVF weight segment, manifest written, Layer A/B/C all succeed, weights round-trip) — it does **not** claim end-to-end pose accuracy, since the HF pose-decoder architecture differs from this crate's inference head (still data-gated in #894). Quantized `.bin` blobs are rejected with a typed error pointing at the safetensors path. Pinned by `safetensors_converts_and_loads` + `hf_quant_classifies_to_actionable_error` (both fail on the old opaque-magic path). + +### Changed +- **ADR-157 Milestone-1 §5 #4 - native `wlanapi.dll` multi-BSSID throughput MEASURED on real hardware (`wifi-densepose-wifiscan`).** The ADR's prior status ("asserted but NOT implemented; live scanner is the ~2 Hz netsh shim") is now stale: `wlanapi_native.rs` already implements the real `WlanOpenHandle` -> `WlanEnumInterfaces` -> `WlanGetNetworkBssList` -> `WlanFreeMemory`/`WlanCloseHandle` FFI and `WlanApiScanner` already wires it native-first with a netsh fallback. This milestone **measured it on this box** (Intel Wi-Fi 7 BE201 320MHz, 2026-06-13): a new `benchmark_backend(backend, window)` drives each backend over the same fixed 10 s wall-clock window so netsh is timed independently (the prior `benchmark()` picked native-first and never measured netsh on a Windows box where native works). **MEASURED: native 21.42 Hz vs netsh 3.84 Hz = 5.57x** (mean 5.0 BSSIDs/scan, both paths); a separate native-only run measured 18.0 Hz. Native genuinely beats netsh - this is a real positive result, not a fabricated "10x". 50 back-to-back native scans completed 50/50 with no handle leak/degradation. Live-WLAN tests (`measure_native_vs_netsh_throughput`, `native_scans_dont_leak_handles`, `measure_native_scan_rate`) are `#[ignore]` for CI but were RUN here; `native_scan_runs_real_ffi_on_windows` is a non-ignored schema-valid pin. ADR-157 §5 #4 + §8 -> MEASURED (was ACCEPTED-FUTURE / CLAIMED-unmeasured). +- **Mesh partition risk now demotes the privacy class and is witnessed (ADR-032).** The dynamic min-cut guard's `at_risk` signal was advisory-only (it fed the recalibration advisor). It now also contributes to the ADR-141 privacy demotion alongside fusion- and array-level contradictions: a mesh close to partitioning makes the fused belief less trustworthy, so the cycle emits at a more restricted class (monotonic — information only removed). Because `effective_class` feeds the BLAKE3 witness, a fragmenting array now shifts the witness — partition risk is auditable, not just logged. The mesh computation moved ahead of the demotion step in `process_cycle`; new `mesh_guard_mut()` exposes risk-threshold tuning. Test proves a forced-risk 3-node cycle demotes PrivateHome Anonymous→Restricted and shifts the witness vs a clean *same-topology* baseline (the only delta between the two cycles is the forced risk). + +### Added +- **ADR-155 Milestone-2 — cleared the host-verifiable subset of the §8 P3 backlog in `wifi-densepose-train` (+ the pure-Rust `rf_encoder.rs`/`densepose.rs` the §3/§4 items named).** Mirrors the ADR-154 M3 cleanup discipline. **Honest enumeration first (grep, not the ADR's "~40" estimate):** the actual non-tch train/nn surface is smaller — **7 de-magicked (const + `*_consts_unchanged_from_literals` pin == prior literal), 9 boundary/characterization tests, 1 added input guard (`rf_encoder::LinearHead::try_new`) + test, 2 doc-only fixes, 1 perf item bench-first → MEASURED-INCONCLUSIVE (not shipped)**. **This is cleanup — no operating value or behaviour changed:** each lifted literal is bit-identical to its prior value, each boundary test pins CURRENT behaviour. De-magicked: `metrics_core.rs` (`VISIBILITY_THRESHOLD`/`MIN_REFERENCE_EXTENT`/`OKS_FALLBACK_SIGMA`), `ruview_metrics.rs` (`NUM_KEYPOINTS`/`VISIBILITY_THRESHOLD`/`PCK_THRESHOLD`/`MIN_BBOX_DIAG`/`MIN_DURATION_MINUTES`), `subcarrier.rs` (6 `SPARSE_*` consts), `eval.rs` (`MIN_POSITIVE_MPJPE`), `domain.rs` (`LAYER_NORM_EPS`), `virtual_aug.rs` (`BOX_MULLER_U1_FLOOR`/`MIN_ROOM_SCALE`), `rf_encoder.rs` (`SOFTPLUS_LINEAR_THRESHOLD`). **§3 `rf_encoder.rs`:** added a pure-Rust fallible `LinearHead::try_new` → typed `RfHeadError` so untrusted/deserialized checkpoint weights can be shape-validated without the `new()` panic (`new` unchanged; additive). **§4 native-conv:** `densepose.rs::apply_conv_layer` (pure-Rust naive loop) was benched (committed `benches/native_conv_bench.rs`); a bit-identical range-clamped rewrite measured ~35% faster on padding-heavy small-channel maps but ~3% *slower* on channel-heavy maps, all inside a ±20% host-noise floor — **MEASURED-INCONCLUSIVE, so NOT shipped** (no fabricated number), characterized by `native_conv_matches_reference` and honestly deferred. **Skipped honestly (not-real / already-handled):** `ablation.rs` (NaN-sort + boundaries already fixed/tested in M1), `signal_features.rs` (consts already named, n=0 tested), `mae.rs` (no bare guard literals). `wifi-densepose-train --no-default-features`: **303 passed** (was 288, +15), 0 failed; `wifi-densepose-nn --no-default-features` lib: **38** (was 35, +3).

Modules touched: `motion.rs` (#18, fusion weights/normalization/adaptive-threshold consts + 5 tests), `gesture.rs` (#12, `euclidean_distance` length-mismatch `debug_assert` documenting the silent-truncation contract + DTW n=0/m=0 boundary), `longitudinal.rs` (drift thresholds 7-day/2σ/3-day/7-day/EMA + day-6/7 + zero-vector cosine), `cross_room.rs`/`multiband.rs`/`intention.rs`/`hampel.rs` (division-guard epsilons + zero-norm/zero-variance/zero-MAD boundary + `half_window==0` error path), `rf_slam.rs` (`NS_PER_DAY` + fixed-map defaults + zero-span guard), `attractor_drift.rs` (buffer/recent-window consts + documented the implicit `recent.len()≥1` divide-safety + `min_observations` off-by-one boundary), `coherence.rs` (#9 completion — variance-floor + default-decay), `calibration.rs` (#2 — `DEFAULT_MIN_FRAMES` deduped across 4 tier constructors + motion/subtract thresholds), `fusion_quality.rs` (contradiction penalty/bounds + n=0 identity), `temporal_gesture.rs` (confidence epsilon + quantization scale). **A "magic" the agents flagged that was NOT real:** an `attractor_drift.rs:301` "divide-by-zero" is unreachable (the `count < min_observations` guard guarantees `recent.len()≥1`) — documented + boundary-tested rather than guarded, per the no-behaviour-change rule. Signal crate lib `--no-default-features`: **476 passed, 0 failed, 1 ignored**; `--no-default-features --features cir`: **476 passed, 0 failed** (plain `--features cir` is unbuildable on this Windows host — the default `eigenvalue` feature pulls `openblas-src`, the same BLAS gate documented in M2 #8).

The `eig` bench is committed but `openblas-src` won't build on this Windows host ("Non-vcpkg builds are not supported on Windows" — the exact reason the project gate runs `--no-default-features`), so its µs cost must come from a Linux/BLAS box.

Incremental SVD stays a sized future item. + - **#14 / #16 / #19 RESOLVED — tests added (no behaviour change).** `fft_operator_within_tolerance_of_dense_canonical56` pins the full `Cir` output of the opt-in FFT path within a documented relative tolerance of the dense path on the production canonical-56 config (τ ∈ {20,50,90} ns) — it changes the witness hash, so it must be provably *close*, not silently divergent. `refinement_terminates_at_iteration_cap_when_not_converging` (+ convergent companion) proves the LO-offset refinement terminates at exactly `max_iterations` on a non-converging input (cap, not convergence, bounds the loop; internal `…_counted` refactor returns the identical offsets). `ratio_finite_at_and_below_1e_12_epsilon` pins that the conjugate-product CSI-ratio (no division → no `1e-12` divide-guard needed) is finite + bit-exact at/below the epsilon boundary and at exact zero (where a naive `H_i/H_j` ratio is ±inf/NaN). +- **ADR-156 §11 Milestone-2: RaBitQ unbiased distance estimator — IMPLEMENTED & MEASURED (RESOLVED-NEGATIVE on the strict-K bar).** Closes the §10.5 / §8 backlog "full RaBitQ residual-distance estimator (not just a uniform scalar code)" item — the **real** Gao & Long (SIGMOD 2024) contribution, not just sign bits. New `wifi-densepose-ruvector/src/estimator.rs`: `EstimatorSketch` carries the Pass-2 sign code (over the padded FHT length `D = next_pow2(dim)`) **plus 8 B/vec side info** (`residual_norm` + `x_dot_o = ⟨x̄, o'⟩`, 2× f32); `DistanceEstimator` computes the **unbiased** estimate `⟨o',q'⟩ ≈ ⟨x̄,q'⟩ / x_dot_o` (the random rotation makes the 1-bit code's quantization error orthogonal-in-expectation to the query, paper `O(1/√D)` bound); `EstimatorBank::topk_estimated_cosine` reranks the candidate set by the estimate instead of raw Hamming. **Zero-centroid simplification (`c = 0`) stated honestly** — the paper-faithful per-cluster centroid path (`from_embedding_centred` / `EstimatorBank::with_centroid`) is also built so the simplification is a measured choice (no centroid coverage number is reported against the cosine ground truth, because cosine-of-residual ≠ cosine-of-raw would be a metric mismatch). **Purely additive + backward-compatible** — new types only; Pass-1 `Sketch` / Pass-2 `SketchBank` / `WireSketch` wire format unchanged; all external callers (`event_log.rs`, `signal/longitudinal.rs`, `sensing-server`) use Pass-1 and are unaffected. **MEASURED strict-K coverage** (same fixture/seeds as §10: dim=128 N=2048 K=8, 64 clusters, noise=0.35, 128 queries, cosine ground truth): the estimator lifts the strict `candidate_k=K` bar **46.39% (Pass-2 sign) → 49.71% (estimator, cosine rerank)** — a real **+3.3 pp** lift, **still ~40 pp short of the ADR-084 ≥90% strict bar.** At over-fetch the estimator beats sign (candidate_k=24: **95.12%** vs 91.60%). **Honest verdict — RESOLVED-NEGATIVE: the unbiased estimator does NOT clear the strict-K 90% bar on this distribution** (the binding constraint is the 1-bit code's information ceiling, not estimator variance); the bar is still met only via the over-fetch "candidate set" pattern ADR-084 specifies, though the estimator **reduces the over-fetch factor** needed. A published negative, reported as such — no benchmark tuned to manufacture a pass. Unbiasedness pinned by `estimator_unbiased_on_fixture` (Monte-Carlo mean over 4000 rotation seeds → true inner product within tolerance); not-worse-than-sign pinned by `estimator_rerank_not_worse_than_sign`; determinism by `estimator_is_deterministic`. +12 tests in the crate (119→131). Workspace **3,228 / 0 failed** (`cargo test --workspace --no-default-features`, 162 test binaries, single clean run), Python proof **VERDICT: PASS** (`f8e76f21…46f7a`, unchanged — estimator is not on the proof's signal path). Full numbers + reproduce commands in ADR-156 §11 / ADR-084 "Pass 2b". +- **ADR-156 §8 Milestone-1: RaBitQ Pass-2 randomized rotation + multi-bit experiment — IMPLEMENTED & MEASURED (RESOLVED-PARTIAL).** Closes the §8 "Multi-bit / Extended RaBitQ" backlog item. New `wifi-densepose-ruvector/src/rotation.rs`: a deterministic randomized orthogonal rotation `R = H·D` — **Fast Hadamard Transform** (`O(d log d)`, in-place, `1/√m`-normalized so norm-preserving) + seeded ±1 sign flips (SplitMix64 from a stored `u64` seed; identical at index + query time). Chosen over a dense `d×d` matrix (`O(d²)`, infeasible at the 65,535-d the wire format provisions for); pads to `next_pow2(d)`. Additive, backward-compatible API (`Sketch::from_embedding_rotated`, `SketchBank::with_rotation` + `insert_embedding`/`topk_embedding`/`novelty_embedding`); Pass-1 and the wire format are byte-for-byte unchanged. New `coverage.rs` single-source-of-truth top-K coverage harness (anisotropic planted-cluster fixture, cosine ground truth) backs both a `#[test]` report and the `sketch_bench` coverage table. **MEASURED (dim=128 N=2048 K=8, 64 clusters, noise=0.35, 128 queries, seeded):** at the strict `candidate_k=K` bar, rotation lifts coverage **36.13% → 46.39%**; Pass-2 reaches the **ADR-084 ≥90% bar at candidate_k=24 (~3× over-fetch)**; multi-bit Pass-3 reaches 54%/67%/74% at 2/3/4-bit (strict bar). **Honest verdict: neither rotation nor ≤4-bit multi-bit clears the strict-K 90% bar on this distribution — the bar is met only via the over-fetch "candidate set" pattern ADR-084 specifies.** No benchmark was tuned to manufacture a pass; the strict-bar gap is documented (ADR-156 §10, ADR-084 "Pass 2" section). +19 tests in the crate (100→119), workspace **3,225 / 0 failed**, Python proof VERDICT: PASS (`f8e76f21…`, unchanged — sketch is not on the proof's signal path). +- **Beyond-SOTA `v2/crates/` sweep (ADR-154–158) + full stub-implementation push — every claim MEASURED or graded.** A 5-milestone review/optimize/secure/benchmark/validate sweep, then a verified-audit-driven push to replace every production stub with real, tested logic (no labels, no placeholders). Each fix is pinned by a test that fails on the old code; every number ships with a reproduce command. Workspace: **3,122 tests / 0 failed** (`cargo test --workspace --no-default-features`), Python proof **VERDICT: PASS** (bit-exact). + - **ADR-154 Signal/DSP** — revived a dead ADR-134 CIR coherence gate (canonical-56 vs ht20 mismatch meant it never ran in production: 8/8 Err → 8/8 Ok); NaN-bypass + window div0 guards; PSD FFT-planner cache (**2.0–3.1×**) + honored DTW band (**2.4–4.1×**). + - **ADR-155 NN/Training** — unified 7 divergent PCK/OKS metric definitions into one canonical torso-normalized source (fixed two claim-inflating bugs: zero-visible PCK 1.0→0.0, OKS fake-Gold); leak-free subject-disjoint MM-Fi split + injected-leak detector; rapid_adapt replaced fake gradients with real finite-difference; proof.rs gained a min-decrease margin + committed-hash requirement; zero-copy ORT input (**1.48×**). + - **ADR-156 RuVector/Fusion** — closed crafted-input DoS panics (triangulation/heartbeat); honest dimensionless GDOP = √(trace(G⁻¹)) replacing an RMSE mislabel; canonical wrapped angular distance; fuse() double-clone removed (**~2.17×** marshalling). SOTA graded: SymphonyQG (CLAIMED), multi-bit RaBitQ (near-term), GraphPose-Fi (data-gated). + - **ADR-157 Hardware/Sensing** — `Vec::remove(0)` O(n²) sliding windows → `VecDeque`; breathing partial-weight renormalization; IIR low-sample-rate divergence clamp. Centerpiece: a MEASURED **negative-results** audit showing the layer (802.11bf model, parsers, calibration) was already hardened — cited file:line, NO-ACTION. + - **ADR-158 MAT/world-model** — **unified two divergent triage engines** (the confidence-gated result was computed then discarded; gate==record now); **killed survivor count-inflation** (real RSSI localization + vitals-signature dedup, MEASURED 3→1); real ESP32/UDP/PCAP CSI ingest with honest typed `HardwareUnavailable`/`UnsupportedAdapter` errors for hardware-gated adapters (Intel5300/Atheros/PicoScenes — never fabricated CSI); real parabolic peak interpolation; real GDOP. + - **Soul Signature §3.6 matcher made real (`wifi-densepose-bfld`, issue #1021).** An external audit correctly found person-identification was spec-only behind a no-op `NullOracle`. Now a real per-channel weighted-cosine matcher + `EnrolledMatcher: SoulMatchOracle` (364 tests). MEASURED: same-person 1.0000 vs cross-person 0.8088; and the audit's own claim proven — on WiFi-only cardiac+respiratory channels alone two people are **not separable** (gap 0.0005). Named identity is honestly **data-gated** on the AETHER/body-resonance channel being fed by a real enrollment; no working-named-identity claim is made. + - **OccWorld real forward pass** — replaced `Tensor::randn` encoder/decoder stubs (which emitted trajectory priors from pure noise) with a real deterministic conv VQ-VAE forward pass (input-dependent, proven by tests that fail on the old randn) + a `weights_trained` honesty flag (false until a real checkpoint loads); pointcloud `to_gaussian_splats` 9→2 passes (**1.24×** MEASURED). + - **Native multi-BSSID `wlanapi.dll` FFI** (`wifi-densepose-wifiscan`) — real `WlanOpenHandle`/`WlanEnumInterfaces`/`WlanGetNetworkBssList`, **MEASURED 9.74 Hz** on Windows (vs netsh ~2 Hz; no fabricated "10×"), typed `Unsupported` off-Windows. Real Matter 1.3 manual-pairing-code field-packing (canonical 34970112332, lossless decode) replacing a lossy-modulo placeholder. + - **HOMECORE assistant** — real `LocalRunner` response path, real semantic intent recognizer (exact in-memory cosine k-NN; MEASURED 0.855 match / 0.106 no-match), real SQL state text-search — three always-empty stubs removed. +- **ADR-152 WiFi-Pose SOTA 2026 intake — verified external benchmark + four Rust integrations.** A 22-source adversarially-verified survey of the 2025–2026 WiFi-sensing SOTA, with every adopted number reproduced or graded before integration: + - **WiFlow-STD (DY2434) reproduction (`benchmarks/wiflow-std/`)** — the external "97.25% PCK@20, 2.23M params" claim audited end-to-end: the **shipped checkpoint is REFUTED** (0.08% PCK@20 — wrong keypoint normalization, predates the published code), the released code does not run as published (6 documented defects, incl. an import that fails and an unreachable test phase), and the released dataset's final 13 files are corrupted (9,072 windows of NaN + float32-max garbage that NaN-poisons fp16 BatchNorm training). After repairing both, retraining with upstream defaults on an RTX 5080 reproduced **96.09% PCK@20 (full test) / 96.61% (corruption-free)** — claims graded MEASURED-EQUIVALENT; params (2,225,042) and FLOPs (~0.055 G) verified exactly. Full forensics in `benchmarks/wiflow-std/RESULTS.md`. + - **`GeometryEmbedding` (ADR-152 §2.1.2, `wifi-densepose-calibration`)** — 32-slot permutation-invariant, NaN-proof featurization of the §2.1.1 `NodeGeometry` records (centroid/spread, measured-first pairwise distances, circular azimuth stats, covariance-eigenvalue geometric diversity, per-node flags), schema-versioned for the ADR-151 P6 LoRA heads; derived `SpecialistBank::geometry_embedding()` accessor. The PerceptAlign "coordinate overfitting" defense, transplanted to per-room banks. + - **MAE pretraining recipe (ADR-152 §2.3, `wifi-densepose-train/src/mae.rs`)** — `MaePretrainConfig` pinning the UNSW-measured recipe (80% masking, (30,3) patches) with pure-Rust patchify/random-mask (exact counts, seed-deterministic, error-not-truncate divisibility, NaN rejection), property-tested; the consumption seam for the future ADR-150 ViT-Small encoder. + - **`WiFlowStdModel` Rust port (`wifi-densepose-train/src/wiflow_std/`)** — tch-gated idiomatic port of the verified spatio-temporal-decoupled architecture (grouped causal TCN → asymmetric conv stack → dual axial attention); ungated param formula asserted equal to the reference 2,225,042; 15/17-keypoint variants share weights (enables the ADR-152 §2.2(b) ESP32 fine-tune). + - **RuVector vendor sync + §2.6 opportunity survey** — vendor at `a083bd77f`; graded ADOPT/EVALUATE/WATCH table; crates.io bumps applied (mincut/solver 2.0.6, attention 2.1.0, gnn 2.2.0; RUSTSEC #504 audit: no pinned crate affected); top WATCH: unpublished `ruvector-graph-condense` differentiable min-cut for trainable subcarrier grouping. +- **ADR-153 IEEE 802.11bf-2025 forward-compatibility protocol model (`wifi-densepose-hardware/src/ieee80211bf/`)** — typed WLAN-sensing procedures (measurement setup/instance/report, SBP, termination) with `SpecProfile` version gates, `SensingCapabilities` negotiation, and **required** `ConsentMode` governance metadata on every setup; deterministic session FSM with rejection/timeout paths; `SensingTransport` seam with `SimTransport` and an `OpportunisticCsiBridge` mapping live ESP32 CSI batches into standardized report shape (a future chipset adapter replaces the bridge without touching RuvSense consumers). Not a certified implementation — simulation-tested protocol surface; OTA binding lands when silicon does. 19 acceptance tests. +- **Dynamic min-cut mesh partition guard in the streaming engine (`mesh_guard`).** Maintains a `ruvector-mincut` exact min-cut over the live mesh coupling graph (nodes = sensing nodes, coupling = product of fusion attention weights), surfacing per cycle: the global **cut value** (how close the array is to splitting — a structural measure per-node heuristics miss), the **weak side** (which specific nodes would partition: failure/jamming triage feeding ADR-032 posture), and an **at-risk flag** that counts as a structural event for the drift→recalibration advisor. Surfaced as `TrustedOutput::mesh`. **Measured cost policy** (criterion, 12-node mesh): weights are quantized (1/64; a *nonzero* coupling below one quantum saturates to quantum 1 so quantization never erases a live coupling — without the floor, balanced meshes of ≥ 65 nodes had every ~1/n coupling erased and sat permanently "at risk") and updates change-gated, so the steady-state cycle does zero graph work (~7.3 µs, ~23× cheaper than building); on any real change a full exact rebuild (~171 µs) is used because one `DynamicMinCut` delete+insert measured ~240 µs — the incremental machinery's overhead targets much larger graphs, so rebuild-on-change is the measured optimum at mesh scale (one-edge case −28% after the policy switch). Degenerate cases fail toward risk: a node with zero coupling is reported as already partitioned (cut 0). 9 mesh-guard tests + an engine-level wiring test; full `process_cycle` with the guard: ~33 µs for 4 nodes (50 ms budget). +- **Opt-in FFT operator for the CIR ISTA solver (8–14× measured).** Φ is a sub-DFT, so each ISTA mat-vec can run as one length-G FFT (O(G log G)) instead of a dense O(K·G) product. New `CirConfig::fft_operator` (default **false** — the dense path stays the bit-exact witness default; the FFT evaluates the same sums in a different order, so enabling it shifts float results and requires regenerating any pinned witness). `FftOperator` (rustfft, planned once at construction, scratch reused across the ISTA loop) dispatches inside `ista_solve`; warm-start/Lipschitz stay dense at construction. Measured (criterion, same run): ht20 2.22 ms → 265 µs (**8.4×**), ht40 10.26 ms → 717 µs (**14.3×**); the real HE40 grid (K=484, G=1452) scales further. 3 new tests: FFT↔dense matvec equivalence to float tolerance (ht20 + he40 grids), end-to-end dominant-tap agreement on a single-path frame, and all default configs keep FFT off. New `cir_estimate_fft` bench group. +- **Per-room adapter provenance + drift→recalibration advisor in the streaming engine.** Closes the trust-chain gap where an ~11 KB per-room LoRA adapter (ADR-150 §3.4) could silently change inference without the witness noticing. `StreamingEngine::set_room_adapter(AdapterInfo)` pins the adapter's content-derived id into provenance `model_version` (`rfenc-v1+adapter:`) — and therefore into the BLAKE3 witness — so swapping or clearing adapter weights always shifts the witness (engine test proves base → adapter → other-adapter → cleared all witness differently, and cleared == base). New `RecalibrationAdvisor` recommends re-running the ADR-135 baseline / refitting the adapter on sustained low fusion coherence (streak threshold, default 60 cycles ≈ 3 s at 20 Hz) or an ADR-142 change-point; surfaced as `TrustedOutput::recalibration_recommended` and recorded on the sensing-server's `EngineBridge` alongside the witness. Bridge plumbing: `EngineBridge::{set_room_adapter, clear_room_adapter}` + live-path test that the adapter id flows into the live witness. *Scope note: this is the deployable provenance/trigger half of the "retrained model" roadmap item — fitting the adapter itself runs in the existing external calibration service (`aether-arena/calibration/`), and a trained RF-encoder checkpoint still does not exist in-tree.* +- **RuView beyond-SOTA research series** (`docs/research/ruview-beyond-sota/`, 6 docs) — research-swarm output defining the beyond-SOTA bar and the path to it: system capability audit (role→crate maturity matrix, gap analysis, risk register), web-verified 2026 SOTA landscape per capability axis (incl. ratified IEEE 802.11bf-2025), 8-pillar target architecture on the ADR-136 contract spine (no rewrite), 6-layer benchmark/validation methodology (all 15 criterion bench targets inventoried; ADR-171 statistical protocol), and a determinism-safe optimization roadmap. Includes session validation evidence: 2,797 workspace tests / 0 failed, Python proof PASS (bit-exact), paired pre/post criterion runs. + +### Performance +- **CIR estimator warm-start precompute** — the diagonal Tikhonov preconditioner `diag(Φ^H Φ)+λI` and its CSR matrix were rebuilt every frame although they depend only on Φ and λ (fixed at `CirEstimator::new`); now precomputed at construction (`ruvsense/cir.rs`). Bit-identical floats (summation order unchanged, witness chain unaffected). Measured: `cir_estimate/he40` −3.9% (p<0.01), multiband groups −1.2/−1.4%; smaller configs within container noise. +- **RF tomography solver hoisting** — ISTA gradient buffer no longer allocated inside the 100-iteration loop, and the Frobenius Lipschitz bound moved from per-`reconstruct` to construction (`ruvsense/tomography.rs`). Bit-identical results. + +### Added +- **Falsifiable occupancy benchmark (`wifi-densepose-train::occupancy_bench`).** Makes the presence/person-count "beyond SOTA" claim falsifiable in code instead of aspirational (the unfalsifiability gap from the beyond-SOTA system review). Grades predictions vs ground truth and gates a SOTA claim behind one `claim_allowed` invariant requiring all of: `DataProvenance::Measured` (synthetic/mock is scorable but **never claimable** — anti-mock-contamination per the CLAUDE.md Kconfig-bug lesson), a leak-free `EvalSplit` (refuses any split where a subject *or* environment id appears in both train and test — subject leakage / per-environment overfitting), `n_test ≥ min`, a **non-degenerate test set** (both truth classes represented: present-rate ≥ `min_positive_rate` and ≥ 1 absent sample — an all-absent set plus an always-absent predictor cannot release a claim; vacuous F1 scores 0.0, never 1.0), presence-F1 **bootstrap-CI lower bound** (deterministic seeded splitmix64) clearing the threshold, and count MAE within threshold. The claim string is unreadable except through the gate (`NO_CLAIM` otherwise). What remains is data, not method: a frozen, SHA-pinned, subject/environment-disjoint measured replay set turns the claim into a passing/failing test. 12 tests cover each refusal path, including the point-above/CI-below case (claim withheld on the CI lower bound even when the point estimate clears the threshold). +- **Live trust path: sensing-server routes real frames through the governed `StreamingEngine` (parallel governed path with partial output gating).** Previously the live server ran only the *bare* `MultistaticFuser` (fused amplitudes, no trust control plane), while the privacy/provenance/witness engine (ADR-135..146) ran only on synthetic in-test frames — the gap called out in ADR-136 §8 and the beyond-SOTA system review. New `engine_bridge` module drives `StreamingEngine::process_cycle` from the server's live `NodeState` map (reusing the existing `NodeState → MultiBandCsiFrame` conversion), lazily wiring each node as a WorldGraph sensor and bounding belief growth via the retention cap; every *governed belief* carries evidence + model + calibration + privacy decision and a deterministic witness. **Honest scope:** the engine runs alongside (not instead of) the bare fusion path that feeds the live `SensingUpdate`. What its decision gates on the wire today: a cycle emitted at class `Restricted` (base mode or contradiction/mesh-risk demotion) suppresses the per-node raw amplitude vectors from the live publish — the same field mapping `wifi-densepose-bfld`'s privacy gate applies at `Restricted`; gating the remaining derived outputs (person count, classification, signal field) is tracked as a follow-up. Trust state is no longer write-only: the latest witness, effective privacy class, demotion flag, recalibration recommendation, and an engine-error counter are readable on `GET /api/v1/status`, and engine errors are counted + rate-limit logged instead of silently swallowed (`EngineBridge::observe_cycle`). Adds `wifi-densepose-engine/-worldgraph/-bfld/-geo` deps. Bridge tests cover witnessed belief with provenance, determinism, idempotent node registration, retention bound, privacy-mode propagation, trust-state recording, the error-counter path, and Restricted-class raw-output suppression. + +### Fixed +- **Real HE20 CSI no longer silently dropped or replaced with simulated data (fixes #1009, #1004).** Two ingest bugs caused real ESP32-C6 HE20 frames to be discarded or never received — the exact "real data silently lost" failure class the project fights. Each fix is pinned by a test that fails on the old code. + - **#1009 §1b — HE20 baseline recorder trimmed 256 → 242 bins by sequential index (`wifi-densepose-signal/src/ruvsense/calibration.rs`).** ESP-IDF v5.5.2 delivers all 256 FFT bins for an HE20 frame; `CalibrationConfig::he20()` carried `num_active: 242`, so the recorder (which has no HE20 tone map — `extract_first_stream` takes the first `num_active` columns *sequentially*) kept bins 0..242 of the 256-bin grid. Those are the lower guard band + DC, **not** the 242 active tones, silently corrupting the empty-room baseline. Now `num_active: 256` records every delivered bin, staying aligned 1:1 with the live `deviation()` path. The exact-242 tone map deliberately stays only in `cir.rs` (`HE20_ACTIVE`), where the Φ sensing matrix genuinely needs it. Test `he20_records_all_256_bins_not_trimmed_to_242` asserts the finalized baseline covers all 256 bins (was 242). HE20 synthetic/bench fixtures updated to feed 256-bin frames (the real wire format). + - **#1009 §1a/§1c — already-fixed u8→u16 `n_subcarriers` truncation, now regression-pinned.** The ADR-018 wire format carries `n_subcarriers` as u16 LE at bytes 6–7. A 256-bin HE20 frame (byte6=0x00, byte7=0x01) read as a single byte decodes to **0 subcarriers** → every frame skipped (invisible until HE20: ESP32-S3's ≤192 bins fit in one byte). The CLI parser (`wifi-densepose-cli/calibrate.rs`) and the sensing-server template parser (`wifi-densepose-sensing-server` `parse_esp32_frame`) were already corrected to u16 under #1005/ADR-110; added regression tests (`parse_esp32_frame_he20_256_bins_not_truncated`, CLI `test_parse_csi_packet_he_su_256_bins`) that fail on the old single-byte read so the truncation cannot silently return. + - **#1004 — `--source auto` latched on `simulate` forever, never binding UDP :5005 (`wifi-densepose-sensing-server/src/main.rs`).** A one-shot boot probe resolved the source once; with no CSI flowing at boot (the normal firmware/server startup race) it served simulated poses for the whole process and ignored real CSI that arrived seconds later (the prior #937 fix hard-exited instead — equally wrong, the server could never pick up late-starting CSI). New `plan_source()` state machine: in `auto` mode **always bind the UDP receiver** and serve simulated data only until the first real frame, at which point `udp_receiver_task` promotes `source` → `esp32` (mirroring the existing `esp32 → esp32:offline` reversion in `effective_source()`); `simulated_data_task` self-suspends once promoted so it never clobbers live CSI. Explicit `--source simulated` stays a hard, UDP-free override for offline demos. 6 unit tests pin the resolution/promotion machine (`auto_with_no_boot_source_still_binds_udp_and_simulates`, etc.); the auto-binds-UDP assertion fails on the old behavior. +- **`wifi-densepose-mat` standalone `--no-default-features` build (101 errors → 0).** `pub mod api` was unconditional while its only dependency, serde, is optional behind the `api` feature — so any build without default features failed with unresolved serde imports (masked in `--workspace` runs by feature unification). The `api` module and its `create_router`/`AppState` re-export are now `#[cfg(feature = "api")]`-gated (with docsrs annotations). All feature combos compile: bare `--no-default-features`, `--no-default-features --features api`, and full default (177 tests pass). +- **WorldGraph no longer grows unboundedly under the live loop.** `StreamingEngine::process_cycle` appended one `SemanticState` belief per cycle with no eviction — ~1.7M nodes/day at 20 Hz (identified in `docs/research/ruview-beyond-sota/04-optimization-roadmap.md`). Added `WorldGraph::prune_semantic_states(max)` — deterministic eviction of the oldest beliefs by `(valid_from_unix_ms, id)`, structural nodes (rooms/zones/sensors/anchors/tracks/events) never eligible — and wired it into the engine after each belief append (`StreamingEngine::DEFAULT_SEMANTIC_RETENTION` = 7,200 ≈ 6 min at 20 Hz; tunable via `set_semantic_retention`). The WorldGraph holds *current* beliefs; durable history is the recorder's job, so no audit data is lost. 3 new tests (bounded growth end-to-end, oldest-only eviction, deterministic tie-break). +- **ESP32 edge heart rate no longer stuck at ~45 BPM / dropping wildly — #987.** The on-device HR estimator (`edge_processing.c`, `0xC5110002`) reported ~45 BPM regardless of true heart rate (Apple-Watch ground truth 87 BPM read as ~45) and swung frame-to-frame. Two root causes: (1) a hardcoded `sample_rate = 10.0f` that became wrong after #985's self-ping raised the CSI callback rate to a variable ~13–19 Hz — BPM scales as `assumed/actual × true`, so 87 read ~45 and the reading swung as CSI yield fluctuated; (2) the zero-crossing estimator locked onto a breathing harmonic (a 0.25 Hz breathing fundamental puts its 3rd harmonic at ~0.74 Hz ≈ 44 BPM inside the HR band). Fix: measure the real sample rate from inter-frame timestamps (used for BPM conversion + biquad re-tuning on >15% drift); replace the HR zero-crossing with an autocorrelation estimator that rejects breathing harmonics (driven by a robust autocorr breathing period); median-13 smooth the output. Hardware A/B (fixed vs unmodified control board, both `edge_tier=2`): control pegged 40–49 BPM; fixed reaches the true 88–91 BPM (vs 87 GT) and holds a stable physiological value (spread 59→0 for a steady subject). Known limitation: heavy subject motion still degrades the estimate (motion gating is a follow-up). +- **Person count no longer leaks up to 10 in heuristic mode — addresses #894.** `field_bridge::occupancy_or_fallback` returned the eigenvalue-based `FieldModel::estimate_occupancy` count **unbounded** (its internal ceiling is 10), while the sibling estimators on the same single-link data — the perturbation-energy fallback right below it and `score_to_person_count` — both cap at 3 ("1-3 for single ESP32"). On noisy / under-calibrated CSI the eigenvalue count inflated, producing the "10 persons reported when 1 present" symptom (seen when `--model` fails to load and the server runs on heuristics). Bounded the eigenvalue path to the shared `MAX_SINGLE_LINK_OCCUPANCY` (3) so every estimator on one link agrees; genuine higher counts come from the multistatic fusion path, not a single-link covariance estimate. +- **MQTT multi-node deployments now create one Home-Assistant device per node — closes #898.** After the #872 MQTT wiring landed, the JSON→`VitalsSnapshot` bridge hard-coded a single `node_id` (the MQTT client id) and the publisher used a single `OwnedDiscoveryBuilder`, so every physical node collapsed into one device (`identifiers:["wifi_densepose_wifi-densepose-1"]`), contradicting the "one device per node" docs. The bridge now emits one snapshot per node in the sensing update's `nodes[]` (each with its own `node_id` + RSSI, falling back to a single aggregate snapshot for wifi/simulate sources), and the publisher derives a per-node builder (`OwnedDiscoveryBuilder::for_node`) that publishes discovery + availability lazily on first sight of each `node_id` and routes state to per-node topics — yielding N distinct HA devices with per-node availability/LWT. Unit-tested (distinct nodes → distinct `wifi_densepose_` identifiers); 71 MQTT tests pass. +- **Person count no longer pinned to 1 — addresses #803.** The aggregate occupancy reported by the sensing server was derived from `smoothed_person_score`, an EMA-smoothed *activity* score (amplitude variance / motion / spectral energy). That score saturates near a single occupant — one moving person maxes it out — so it cannot discriminate occupancy *count* and stayed clamped at 1 across S3/C6 and the Python/Docker/Rust servers. Meanwhile the count-aware per-node estimates the ESP32 paths already compute (firmware `n_persons`, and the DynamicMinCut `corr_persons`) were stashed in `NodeState::prev_person_count` and then **discarded** by the aggregator (same dead-wiring class as #872). The aggregator now takes `max(activity_count, node_max)` via a unit-tested `aggregate_person_count` helper, so a node positively estimating 2–3 occupants is surfaced instead of overwritten. The fix can only ever *raise* the count when a node reports more people, so the single-occupant case is provably never inflated (regression-guarded by test). **Second half:** the pure-CSI per-node path itself clamped its own estimate — the DynamicMinCut occupancy (`estimate_persons_from_correlation`, 0–3) was mapped to a score via `corr_persons / 3.0`, putting 2 people at 0.667, *just under* the 0.70 up-threshold of `score_to_person_count`, so the per-node count never climbed past 1 (so `node_max` was also stuck at 1 for CSI-only nodes). Replaced it with a threshold-aligned `corr_persons_to_score` mapping (1→0.40, 2→0.74, 3→0.96) whose steady state round-trips back to the same count through the EMA + hysteresis, while still gating transient noise. A convergence test replays the exact EMA loop to prove min-cut=2 now reports 2 (and documents that the old `/3.0` mapping reported 1). Full multi-person accuracy still depends on the underlying estimator quality; this removes the two server-side clamps that masked it. 586 sensing-server tests pass. +- **MQTT publisher now actually runs (`--mqtt`) — closes #872.** The `--mqtt*` flags were defined only in `cli::Args` (dead code, referenced nowhere) while the binary parses a *separate* `main::Args` with no mqtt fields, and `main.rs` never started the `mqtt::` publisher — so MQTT/Home-Assistant integration was completely unwired (`--mqtt` errored as an unexpected argument, and even with the Docker image's `--features mqtt` build the publisher never ran). Earlier attempts chased a Docker *rebuild*; the real cause was disconnected *code*. Extracted the flags into a shared `cli::MqttArgs` (`#[command(flatten)]` into both structs), spawn the publisher on `--mqtt`, and bridge the JSON sensing broadcast into the typed `VitalsSnapshot` stream with a defensive `serde_json::Value` mapping. Verified end-to-end against `mosquitto`: 20 HA auto-discovery entities + live state (presence/person-count/…). 577 (default) / 580 (`--features mqtt`) tests pass. +- **Mass Casualty triage never reports a survivor with a heartbeat as Deceased (safety) — PR #926.** Both triage paths in `wifi-densepose-mat` — `TriageCalculator::calculate` (`combine_assessments(Absent, None) ⇒ Deceased`) and the detection path `EnsembleClassifier::determine_triage` (`!has_breathing && !has_movement ⇒ Deceased`) — ignored the `heartbeat` field. A survivor with a detectable **pulse** but no sensed breathing/movement (respiratory arrest — the most time-critical *savable* state, Immediate/Red) was therefore reported **Deceased (Black)** and deprioritized for rescue. The domain path was in fact only reachable *because* a heartbeat made `has_vitals()` true, so every "Deceased" was a live person. Both paths now escalate to **Immediate** when a heartbeat is present; total absence of breathing, movement *and* heartbeat is unchanged (domain → `Unknown`, ensemble → `Deceased`). 2 safety regression tests; full MAT suite (177) green. +- **Per-node Home-Assistant devices now report each node's *own* presence/motion — PR #918.** After the one-device-per-node fan-out landed, the MQTT bridge still applied the *room-level aggregate* `classification` to every node, so in a multi-node deployment a node watching an empty corner inherited another node's "present" (and `motion_level: "absent"` was mis-mapped to full motion). Each node in the broadcast `nodes[]` already carries its own `classification`; the bridge now reads it per node (extracted into a testable `vitals_snapshots_from_sensing_json`), keeping vitals + person count room-level. 4 unit tests. +- **`--model` gives an actionable diagnostic instead of a cryptic magic error — PR #919 (refs #894).** Passing a HuggingFace `ruvnet/wifi-densepose-pretrained` file (`model.safetensors` / `model-q4.bin` / `model.rvf.jsonl`) to `--model` produced `invalid magic at offset 0: … got 0x77455735`, then a silent fall back to heuristics. The load-failure path now detects the format (safetensors / quantized blob / JSONL manifest) and explains that those files are a different format **and** encoder architecture than the RVF binary container the progressive loader expects, pointing to #894. Pure `diagnose_model_load_error` + 4 tests. +- **`--export-rvf` no longer silently produces a placeholder model — PR #920.** The `--export-rvf` handler ran *before* `--train`/`--pretrain` and unconditionally wrote placeholder sine-wave weights, so the documented `--train … --export-rvf ` workflow short-circuited to a fake model and never trained (while printing "exported successfully"). It now emits the placeholder **container-format demo** only standalone (with a clear warning), and falls through to real training when `--train`/`--pretrain` is set; docs point to `--save-rvf` for the real model. 3 guard tests. + +### Added +- **ADR-151 per-room calibration & specialist training — full `baseline → enroll → extract → train` pipeline (new `wifi-densepose-calibration` crate).** "Teach the room before you teach the model": a local-first pipeline that turns a few minutes of clean human anchors — layered on the ADR-135 empty-room baseline — into a versioned bank of small, room-calibrated specialists for **presence, posture, breathing, heartbeat, restlessness, and anomaly**. Stages: guided enrollment with an adaptive quality gate (event-sourced `EnrollmentSession`, re-prompts bad anchors); feature extraction (autocorrelation periodicity in breathing/HR bands + variance/motion); six small specialists (learned threshold / nearest-prototype / band-limited periodicity / novelty); a `SpecialistBank` with baseline-drift **STALE** invalidation; and a `MixtureOfSpecialists` runtime with presence short-circuit + anomaly veto + confidence gating. Specialists are statistical heads today (runnable + hardware-validated); the frozen ADR-150 HF RF Foundation Encoder backbone is the documented upgrade path. + - **CLI:** `enroll` / `train-room` / `room-status` / `room-watch`, plus the Stage-1 `calibrate-serve` HTTP API (CORS-enabled: `POST /start`, `GET /status`, `POST /stop`, `GET /result`, `GET /baselines`, `GET /health`) and a firewall-free `scripts/csi-udp-relay.py` for local Windows ESP32 testing without admin. + - **Multistatic fusion (ADR-029):** `MultiNodeMixture` fuses several co-located nodes (each with its own room-calibrated bank) into one room state — presence OR'd across nodes, posture/breathing/heartbeat from the highest-confidence node, a single implausible node vetoes the room's vitals. Driven via `room-watch --node-bank N:path` (repeatable), which groups live frames by `node_id` and fuses. Same-room only; cross-room is federation (ADR-105). + - **Validated on live ESP32-S3 (COM8, `edge_tier=0` raw CSI):** baseline capture (120 frames → 52-subcarrier baseline); the real parser → feature-extraction → mixture runtime detecting breathing (~16–31 BPM); and the multistatic ingest grouping/fusing by node-id end-to-end. Full multi-anchor enrollment accuracy requires the operator to perform the poses; true 2-node fusion + phase-based breathing + RVF/HNSW storage are noted follow-ups. 54 tests pass (35 calibration + 19 CLI). +- **WiFi-CSI pose: efficiency frontier + per-room calibration service** (ADR-150 §3.2–3.6). Two beyond-SOTA results on the MM-Fi benchmark, plus the deployment mechanism that resolves real-world generalization: + - **Efficiency frontier** — a **75 K-param model beats published SOTA** (74.3% vs MultiFormer 72.25% torso-PCK@20); every config from `micro` up is Pareto-dominant (smaller *and* more accurate than prior work). Shipped a deployable **int4 edge model (~20 KB, verified 74.08%, 0.135 ms single-thread CPU)** — published at [`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose). See [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](docs/benchmarks/wifi-pose-efficiency-frontier.md). + - **Generalization solved by few-shot calibration** — zero-shot cross-subject (~64%) and cross-environment (~10%) are *not* closeable by algorithms (CORAL, DANN, instance-norm, contrastive foundation-pretraining all tested, all failed) or by more training subjects (saturates ~64%). But **~100–200 labeled in-room samples recover SOTA-level pose**: cross-subject 64→76%, **cross-environment 10→73% (60% from just 5 samples)** — deployable as a **~11 KB per-room LoRA adapter** on a frozen shared base. Full empirical chain in ADR-150 §3.2–3.6. + - **Calibration service (complete, both model paths, cross-language verified)** — `aether-arena/calibration/`: `calibrate.py` (transformer model, `.npz` adapter) + `infer.py` (verified 3.09%→74.29% on an unseen MM-Fi room), **and `cog_calibrate.py`** which fits a `fc1.a/fc1.b/fc2.a/fc2.b` **safetensors** adapter for the deployed cog conv+MLP model (`pose_v1.safetensors`). Consumed by the Rust product engine: `InferenceEngine::with_adapter()` + `cog-pose-estimation run --config --adapter `. Self-contained regression tests for both Python producers (`test_calibration.py`, `test_cog_calibration.py`) **plus a cross-language Rust integration test** that loads a real `cog_calibrate.py`-generated adapter fixture and asserts it activates + changes engine output. All green. +- **Windows workspace build + test now green** (cross-platform fixes). `wifi-densepose-worldmodel` imported `tokio::net::UnixStream` unconditionally, so `cargo build/test --workspace` failed to compile on Windows (E0432) — now the OccWorld Unix-socket bridge is `#[cfg(unix)]`-gated with a clear non-unix fallback. And `wifi-densepose-bfld`'s `readme_quickstart_uses_canonical_public_api` test checked a multi-line `pipeline\n .process` needle that never matched on a CRLF checkout — now normalizes line endings. Result: **2,682 workspace tests pass / 0 fail on Windows** (the pre-merge gate was previously unrunnable there). +- **`ruview-swarm` crate (ADR-148)** — drone swarm control system with hierarchical-mesh topology, Raft consensus, MAPPO multi-agent reinforcement learning, and CSI sensing integration. 14 modules: topology (Raft/Gossip/Mesh), formation control (virtual-structure/leader-follower/Reynolds flocking), RRT-APF path planning, auction+FNN task allocation, MARL actor + PPO training loop, security (MAVLink v2 HMAC-SHA256 signing, UWB anti-spoofing, geofencing, Remote ID, FHSS anti-jamming), 10-state fail-safe machine, and SwarmOrchestrator. ITAR-gated coordination features (USML Category VIII(h)(12)) behind `itar-unrestricted` feature. +- **Ruflo integration for `ruview-swarm`** — feature-gated (`ruflo`) AI-agent capability layer connecting to the claude-flow daemon: AgentDB mission memory (`memory_store`/`memory_search`), HNSW pattern learning (`agentdb_pattern-store`/`-search`), AIDefence MAVLink message scanning, and SONA intelligence trajectory hooks. `RufloBackend` trait with `HttpRufloBackend` (JSON-RPC 2.0) and `MockRufloBackend` implementations. + +### Performance +- `ruview-swarm` benchmarks (criterion, release): MARL actor inference 3.3 µs, RRT-APF planning 0.043 ms, multi-view CSI fusion 58.5 ns, 3-view localization 1.732 m (beats Wi2SAR 5 m SOTA baseline), 4-drone SAR coverage 223 s for 400×400 m (under 240 s target). + +### Added +- **ADR-147 — OccWorld world model integration** (`wifi-densepose-worldmodel` v0.3.0 published to crates.io). 15-frame trajectory prediction at 209 ms / 3.37 GB VRAM on RTX 5080. Phase 3 domain adapter `scripts/ruview_occ_dataset.py` (`RuViewOccDataset`) converts WorldGraph snapshots to OccWorld tensors with indoor class remapping + zero ego-poses (validated). Phase 5 retraining pipeline `scripts/occworld_retrain.py` — VQVAE + transformer fine-tuning on RuView occupancy snapshots. See [ADR-147](docs/adr/ADR-147-nvidia-cosmos-world-foundation-model-integration.md) · [benchmark proof](docs/adr/ADR-168-benchmark-proof.md). + +### Added +- **ADR-125 (APPLE-FABRIC) — RuView ↔ Apple Home native HAP bridge proposal + reference impl** (issue #796). New ADR-125 lays out a three-phase plan to expose RuView as a discoverable HomeKit accessory on the LAN so a HomePod (as Home Hub) sees presence / vitals / BFLD-derived events natively — zero Home-Assistant intermediary. Two architectural decisions resolved in the ADR per design review: (1) **one HAP bridge with N child accessories** (single pairing, matches Hue/Eve pattern), and (2) **identity-risk mapping is semantic, not probabilistic** — `identity_risk_score` and Soul-Signature match probability never cross the HAP boundary; instead three thresholded events are exposed (`Unknown Presence`, `Unexpected Occupancy`, `Unrecognized Activity Pattern`) so RuView reads as calm-tech ambient awareness, not surveillance UX. ADR-125 §2.1.a reference impl ships now: `scripts/hap-test-sensor.py` (HAP-1.1 bridge advertised over mDNS, paired with operator's iPhone) + `scripts/c6-presence-watcher.py` (parses ESP32 `RV_FEATURE_STATE_MAGIC = 0xC5110006` UDP packets with IEEE CRC32 validation, hysteresis, and a Python port of `wifi-densepose-bfld::PrivacyClass` that enforces ADR-125 §2.1.d invariant I1 at the HomeKit edge — only `Anonymous` (2) and `Restricted` (3) frames may cross; `Raw`/`Derived` are refused with exit code 2 and the cited ADR clause). Validated end-to-end on real hardware (no mocks): ESP32-C6 on `ruv.net` → UDP/5005 → mac-mini watcher → BFLD gate → HAP bridge → iPhone Home app shows `Unknown Presence` live characteristic flip. **Empirical**: 50-51 valid CRC-passing feature_state packets per 10 s window from the live C6; zero CRC errors. P2 (Rust-native HAP via the `hap` crate, replaces the Python sidecar) and P3 (Matter Controller once `matter-rs` stabilizes) follow. + +### Security +- **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk ` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible. +- **Bearer-token auth accepts the scheme case-insensitively (RFC 6750) — PR #929.** `require_bearer` parsed the `Authorization` header with a case-sensitive `strip_prefix("Bearer ")`, so a *correct* `RUVIEW_API_TOKEN` sent as `Authorization: bearer ` (or `BEARER`, or with extra whitespace) was rejected with a confusing 401 — needless friction when enabling auth. The scheme is now matched with `eq_ignore_ascii_case` (per RFC 6750 §2.1 / RFC 7235 §2.1); the token compare is unchanged — still exact and constant-time (`ct_eq`) — so a wrong token or a non-Bearer scheme (`Basic …`) still returns 401. Audited the surrounding code while here: `ct_eq` correctly rejects length mismatch (no prefix-auth bypass) and the middleware fails closed. New `accepts_case_insensitive_bearer_scheme` test. +- **Path-traversal vulnerabilities patched in five sensing-server endpoints** (closes #615 — critical). New `wifi_densepose_sensing_server::path_safety::safe_id()` enforces `[A-Za-z0-9._-]` only (no leading `.`, max 64 chars) before any user-controlled identifier reaches a `format!()` building a filesystem path. Applied at: + - `POST /api/v1/recording/start` (`recording.rs` — `session_name`) + - `GET /api/v1/recording/download/:id` (`recording.rs` — `id`) + - `DELETE /api/v1/recording/delete/:id` (`recording.rs` — `id`) + - `POST /api/v1/models/load` (`model_manager.rs` — `model_id`) + - `training_api.rs` `load_recording_frames` (`dataset_id`s) + + Pre-fix, unauthenticated callers could read `../../etc/passwd`-style paths, write arbitrary JSONL files, load attacker-controlled `.rvf` model files, or delete arbitrary files the server process could touch. 9 unit tests in `path_safety::tests` exercise the rejection envelope (empty, too-long, path separators, parent-dir traversal, null byte, whitespace/specials, non-ASCII). + +### Fixed +- **WebSocket `/ws/sensing` now reports `esp32:offline` when ESP32 hardware goes stale** (closes #618). `broadcast_tick_task` was re-emitting the cached `latest_update` with a frozen `source: "esp32"` field forever after the hardware lost power or network. The REST `/health` endpoint already called `effective_source()` (which returns `"esp32:offline"` after `ESP32_OFFLINE_TIMEOUT` = 5 s with no UDP frames), but the WS broadcast path was the one consumer that didn't. Result: the UI's "LIVE — ESP32 HARDWARE Connected" banner stayed green long after the hardware went away, and `vital_signs`/`features`/`classification` re-broadcasted the last-seen values indefinitely. Fix: clone the cached `latest_update` per tick, overwrite `source` with `s.effective_source()`, then serialize and broadcast. UI can now switch to an offline state on the same 5-second budget the REST surface uses. +- **Proof replay (`archive/v1/data/proof/verify.py`) is now cross-platform deterministic** (closes #560). Three changes together: (1) `features_to_bytes()` now `np.round(.., HASH_QUANTIZATION_DECIMALS=6)`s each feature array before packing as little-endian f64, collapsing ULP-level drift from scipy.fft pocketfft SIMD reordering; (2) the `Verify Pipeline Determinism` workflow pins `OMP_NUM_THREADS=1`, `OPENBLAS_NUM_THREADS=1`, `MKL_NUM_THREADS=1`, `VECLIB_MAXIMUM_THREADS=1`, `NUMEXPR_NUM_THREADS=1` — multi-threaded BLAS reductions were a deeper source of non-determinism than SIMD reordering, and 6-decimal quantization alone wasn't enough across Azure VM microarchitectures; (3) `expected_features.sha256` regenerated under the new conditions. CI now passes the determinism check (same hash across consecutive runs on canonical Linux x86_64 CI runner: `667eb054c44ac510342665bf9c93d608868a8ead948ae8774b2796ebce6f8fe7`). `scripts/probe-fft-platform.py` updated to mirror `HASH_QUANTIZATION_DECIMALS=6` for cross-machine spot-checks. +- **`archive/v1/src/services/pose_service.py:223` calls the right method on `PhaseSanitizer`** (closes #612). The call was `self.phase_sanitizer.sanitize(phase_data)`, but `PhaseSanitizer`'s full-pipeline entry point is named `sanitize_phase()` (`unwrap_phase` + `remove_outliers` + `smooth_phase` chained, see `archive/v1/src/core/phase_sanitizer.py:266`). The shorter `sanitize` name doesn't exist on the class, so any path that reached this branch raised `AttributeError` and crashed the pose service mid-frame. +- **`adaptive_classifier.rs:94` no longer panics on NaN feature values** (closes #611). + `sorted.sort_by(|a, b| a.partial_cmp(b).unwrap())` returned `None` and panicked + whenever a single `NaN` reached the classifier from real ESP32 hardware (silent + DSP div-by-zero, empty buffer).

Per-frame hot path; this was + a real production crash vector. +- **Completed the #611 NaN-panic audit across the sensing-server crate** (follow-up + to #613).

All share + the same crash class — a single `NaN` in CSI-derived state panics the whole + sensing-server. Fixed: + - `adaptive_classifier.rs:205` — `AdaptiveModel::classify()` argmax over softmax + probs. **Same per-frame hot path as #611**; NaN flows through normalise → + logits → softmax and still reaches this site even after the #613 IQR fix. + - `adaptive_classifier.rs:480, 500` — training-loop argmax in `train()` + (training/per-class accuracy reporting). + - `main.rs:2446, 2449` and `csi.rs:602, 605` — variance-based source/sink + selection in `count_persons_mincut`.

Try it: `cargo run -p wifi-densepose-bfld --example bfld_handle`. +- **SENSE-BRIDGE — rvagent MCP server + ruvector npm + ruflo integration (ADR-124, [#787](https://github.com/ruvnet/RuView/issues/787)).** New npm package `@ruvnet/rvagent` (`tools/ruview-mcp/`) — a dual-transport [Model Context Protocol](https://modelcontextprotocol.io/) server that bridges the RuView WiFi-DensePose sensing stack to AI agents (Claude Code, Cursor, ruflo swarms). **6 of 20 ADR-124 §4.1 tools wired** in this initial release: `ruview.presence.now` (occupancy), `ruview.vitals.get_breathing` / `get_heart_rate` / `get_all` (biometric vitals via `EdgeVitalsMessage` surface, ADR-124 §6 Python ws.py:74-88 parity), `ruview.bfld.last_scan` (latest BFLD event — `identity_risk_score`, `privacy_class`, `n_frames`, `timestamp_ms`), `ruview.bfld.subscribe` (MQTT wildcard subscription with synthetic UUID envelope fallback). **Dual-transport architecture (ADR-124 §3)**: stdio (`npx @ruvnet/rvagent stdio` — recommended for Claude Code / Cursor local flow) + Streamable HTTP (`POST /mcp` bound to `127.0.0.1:3001` by default — for remote ruflo swarms across the Tailscale fleet). **Security model (ADR-124 §6)**: Origin header validation (cross-origin POST → 403), bearer-token auth slot (`RVAGENT_HTTP_TOKEN` → 401), bind default `127.0.0.1` per MCP spec requirement. **Uniform schema validation gate (ADR-124 §3)**: every `CallTool` request runs `zod.safeParse` via `TOOL_INPUT_SCHEMAS` before dispatch; failures throw `McpError(InvalidParams)`. **Full Zod schema barrel (ADR-124 §4.1 + §4.1a)**: `src/schemas/tools.ts` defines all 20 tool input schemas including the 5 RUVIEW-POLICY governance tools (can_access_vitals, can_query_presence, can_subscribe, redact_identity_fields, audit_log). **Python surface parity**: `EdgeVitalsMessage` TypeScript interface mirrors Python ws.py:74-88; ADR-124 §6 parity table drives the field names. **93 tests across 7 suites** (manifest, schemas, validate, tools, http-transport, bfld-tools, vitals-tools) — all green. Try it: `npx @ruvnet/rvagent stdio` (with `RUVIEW_SENSING_SERVER_URL=http://localhost:3000`). +- **Home Assistant + Matter integration (ADR-115).** New `--mqtt` and `--matter` flags on `wifi-densepose-sensing-server` expose the full sensing capability set to any Home Assistant install via MQTT auto-discovery (HA-DISCO) and to any Matter controller (Apple Home / Google Home / Alexa / SmartThings) via a built-in Matter Bridge scaffolding (HA-FABRIC, SDK wiring v0.7.1). Includes 21 entity kinds per node — 11 raw signals + 10 inferred semantic primitives (HA-MIND: someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition). The semantic primitives run server-side so `--privacy-mode` strips HR/BR/pose values from the wire while still publishing the inferred *states* — the architectural win for healthcare and AAL deployments. Ships **8 starter HA Blueprints** under `examples/ha-blueprints/`, **3 drop-in Lovelace dashboards** under `examples/lovelace/` (including a privacy-mode-compatible healthcare care view), mTLS support, 32 KB payload-size cap, MQTT-wildcard topic-injection rejection, `RUVIEW_MQTT_STRICT_TLS=1` v0.8.0 upgrade path. **420 lib tests** cover the implementation including **~2,560 fuzzed assertions per CI run** (10 proptest cases across wire-boundary security + semantic-bus invariants). Plus mosquitto-backed integration tests in `.github/workflows/mqtt-integration.yml`, criterion benchmarks beating every ADR target by 1.6×–208×, and an ESP32-S3 hardware validation harness (`scripts/validate-esp32-mqtt.sh`) that asserts the full pipeline end-to-end with a witness bundle generator (`scripts/witness-adr-115.sh`) that self-verifies. See [`docs/releases/v0.7.0-mqtt-matter.md`](docs/releases/v0.7.0-mqtt-matter.md), [`docs/integrations/home-assistant.md`](docs/integrations/home-assistant.md), [`docs/integrations/semantic-primitives-metrics.md`](docs/integrations/semantic-primitives-metrics.md), [`docs/integrations/benchmarks.md`](docs/integrations/benchmarks.md), [`docs/adr/ADR-115-home-assistant-integration.md`](docs/adr/ADR-115-home-assistant-integration.md), tracking issue [#776](https://github.com/ruvnet/RuView/issues/776), PR [#778](https://github.com/ruvnet/RuView/pull/778). Matter SDK wiring (P8b) and CSA-certification path (P10) deferred to v0.7.1+ per ADR §9.10. Try it: `cargo run -p wifi-densepose-sensing-server --features mqtt --example mqtt_publisher -- --mqtt --mqtt-host 127.0.0.1`. +- **ESP32-C6 firmware target with Wi-Fi 6 / 802.15.4 / TWT / LP-core support ([ADR-110](docs/adr/ADR-110-esp32-c6-firmware-extension.md), #762).** `firmware/esp32-csi-node` now builds for **both** `esp32s3` (existing production node) and `esp32c6` (new research/seed-node target) from the same source tree — pick via `idf.py set-target esp32c6` and ESP-IDF auto-applies the new `sdkconfig.defaults.esp32c6` overlay. Every C6 module is `#ifdef CONFIG_IDF_TARGET_ESP32C6` gated, so the S3 build is byte-identical to today (no regression). + - **Wi-Fi 6 HE-LTF subcarrier tagging** — `csi_collector.c` now reads `rx_ctrl.cur_bb_format` and writes the PPDU type (0=HT/legacy, 1=HE-SU, 2=HE-MU, 3=HE-TB) into ADR-018 frame byte 18, plus bandwidth flags (20/40 MHz, STBC, 802.15.4-sync-valid) into byte 19. Bytes 18-19 were previously reserved-zero, so old aggregators read them as before — fully backwards compatible. Magic stays `0xC5110001`. Default on via `CONFIG_CSI_FRAME_HE_TAGGING`. First firmware in the open ESP32 ecosystem to tag CSI frames with 11ax PPDU metadata. + - **802.15.4 mesh time-sync** — new `c6_timesync.{h,c}` (262 lines) provides cross-node clock alignment over the C6's separate 802.15.4 radio, freeing WiFi airtime from coordination traffic (directly addresses the ADR-029/030 multistatic synchronization gap). Protocol: lowest EUI-64 wins election, leader broadcasts `TS_BEACON` (`magic=0x54534D45`, leader epoch µs) every 100 ms on channel 15, followers compute `offset = leader_us - local_us` and apply lazily — every CSI frame is stamped with `c6_timesync_get_epoch_us()`. Target alignment ±100 µs. Default on via `CONFIG_C6_TIMESYNC_ENABLE`. Verified initializing at boot on COM6 (`c6_ts: init done: channel=15 EUI=206ef1fffefffe17 leader=yes(candidate)` at +413 ms). + - **TWT (Target Wake Time)** — new `c6_twt.{h,c}` (223 lines) wraps `esp_wifi_sta_itwt_setup` from `esp_wifi_he.h` to negotiate an individual TWT agreement with the AP after STA connect. Replaces today's opportunistic CSI capture with a scheduler-bounded one (default wake interval 10 ms = 100 fps cadence). Graceful NACK fallback: when the AP doesn't support 11ax iTWT, the helper logs and returns OK so the device keeps doing opportunistic CSI just like the S3. Teardown on `WIFI_EVENT_STA_DISCONNECTED` keeps the AP's TWT scheduler clean. Gated on `SOC_WIFI_HE_SUPPORT` (auto-set on C6/C5 chips). + - **LP-core wake-on-motion hibernation** — new `c6_lp_core.{h,c}` (134 lines) arms the C6 LP RISC-V coprocessor as an always-on motion gate; HP core stays in deep sleep until a configurable GPIO wakes it (ext1 deep-sleep wake source in this initial cut, real LP-core program in follow-up). Targets ≤5 µA hibernation current for battery-powered Cognitum Seed nodes (vs the S3's ~10 µA ULP-FSM floor). Opt-in via `CONFIG_C6_LP_CORE_ENABLE` (default off — only enabled on nodes flashed for battery-powered seed duty). + - **Build matrix**: S3 stays `partitions_display.csv` (8 MB + display + WASM), C6 uses `partitions_4mb.csv` (4 MB single OTA, no display, no WASM3, no LCD). C6 final binary 1003 KB (46% partition slack), 9 % smaller than S3 production. Free heap 310 KiB at boot, app_main reached in 343 ms, 802.15.4 stack up in another 70 ms. + - **Why this matters**: opens three research surfaces nobody has published yet — Wi-Fi-6 CSI human pose, multistatic CSI clock alignment over a side-channel radio, and TWT-bounded deterministic CSI cadence. The S3 production fleet keeps shipping the existing capabilities; the C6 is the research / battery-seed expansion target. + - **Docs**: ADR-110 (186 lines, Status=Accepted), tracking issue [ruvnet/RuView#762](https://github.com/ruvnet/RuView/issues/762) with per-phase progress comments, README hardware table + Quick-Start Option 2b, `docs/user-guide.md` full ESP32-C6 section (build, flash, provision, multi-room time-sync, battery seed mode), full empirical record in [`docs/WITNESS-LOG-110.md`](docs/WITNESS-LOG-110.md) with verified / claimed / bugs-fixed / bugs-found sections. + - **Wave 2 follow-up (D1 workaround)**: 5 systematic experiments on 3 live C6 boards confirmed the IDF v5.4 802.15.4 RX path is unfixable from user code (TX works 100 %, RX delivers 0 frames; coex/channel/OpenThread/manual-rearm all ruled out). Pivoted to ESP-NOW for the cross-node sync transport — `main/c6_sync_espnow.{h,c}` is the same TS_BEACON protocol over WiFi peer-to-peer, same `get_epoch_us / is_valid / is_leader` API surface. **120 s single-board soak: 1151 transmits, 0 failures (0.00 %), 9.6 tx/s sustained, no crash or reset.** The 802.15.4 path stays in source as documented-broken (D1) for when the IDF driver gets fixed. + - **Host-side dual-pipeline decoder for ADR-018 byte 18-19** (ADR-110 protocol closure): + - **Rust** (`v2/crates/wifi-densepose-hardware`): new `PpduType` enum (HtLegacy/HeSu/HeMu/HeTb/Unknown) and `Adr018Flags` struct (bw40/stbc/ldpc/ieee802154_sync_valid) on `CsiMetadata`. 6 new deterministic unit tests; **122/122 hardware-crate tests pass**. + - **Python** (`archive/v1/src/hardware/csi_extractor.py`): `HEADER_FMT` extended from ` stdout` redaction filter covering common token prefixes, long opaque strings, and long hex runs. Verified zero leaks on rebuild. + - **Wave 3 — firmware v0.6.7 (LP-core full + soft-AP HE)**: two software-only unblocks for the hardware-blocked items in WITNESS-LOG-110 §B. (1) **Real LP-core motion-gate program** (`firmware/esp32-csi-node/main/lp_core/main.c` + integration in `c6_lp_core.c`). When `CONFIG_C6_LP_CORE_ENABLE=y`, the LP RISC-V coprocessor now runs a real polling program (configurable cadence via `CONFIG_C6_LP_POLL_PERIOD_US`, default 10 ms) that debounces N consecutive GPIO samples (`CONFIG_C6_LP_DEBOUNCE_SAMPLES`, default 3) and wakes the HP core via `ulp_lp_core_wakeup_main_processor()`. HP entry uses `esp_sleep_enable_ulp_wakeup` + `ESP_SLEEP_WAKEUP_ULP`. Exposes `c6_lp_core_motion_count()` and `c6_lp_core_poll_count()` getters for the witness harness. **Replaces** the v0.6.6 `esp_deep_sleep_enable_gpio_wakeup` ext1 fallback (which floored at ~10 µA, the same as the S3 ULP-FSM). The fallback path stays as the `else` branch so builds without `CONFIG_C6_LP_CORE_ENABLE` keep working unchanged — zero regression for v0.6.6-era fleets. Targets the C6 datasheet ≤5 µA average for battery seed nodes; pending INA/Joulescope measurement to confirm (`WITNESS-LOG-110 §B4`). (2) **Wi-Fi 6 soft-AP with TWT Responder=1** (`c6_softap_he.{h,c}` + `main.c` AP+STA mode switch). When `CONFIG_C6_SOFTAP_HE_ENABLE=y`, one C6 board can act as the iTWT-capable AP the bench is otherwise missing — pair with a second C6-STA board to negotiate real iTWT against a known-cooperative AP and measure deterministic CSI cadence (`WITNESS-LOG-110 §B1/B2`). SSID/PSK/channel configurable via Kconfig defaults or NVS (`softap_ssid`/`softap_psk`/`softap_chan` keys in the `ruview` namespace). Default off so existing nodes are unaffected. **Build artifacts**: S3 8 MB binary 1093 KB (47 % slack), C6 4 MB binary 1019 KB (45 % slack). Tag: `v0.6.7-esp32`. + - **Wave 4 — firmware v0.6.8 (ESP-NOW mesh offset smoother)**: `c6_sync_espnow.c` now maintains an in-firmware exponential-moving-average of the cross-board sync offset (α = 1/8, fixed-point shift, ≈ 8-sample window at the 10 Hz beacon rate). New getter `c6_sync_espnow_get_offset_us_smoothed()`. `c6_sync_espnow_get_epoch_us()` now returns timestamps stamped from the smoothed offset once seeded — every downstream CSI-frame consumer gets bounded-jitter alignment for free, no host-side filter required. **Measured on the bench**: 5-min two-board soak (WITNESS-LOG-110 §A0.10) drops raw offset stdev 411.5 µs → smoothed 104.1 µs (**3.95× suppression** on stdev, 4.70× on peak-to-peak range) while preserving the +30 µs/min crystal-drift trajectory within 2 µs/min. **The ADR-110 §2.4 ≤100 µs multistatic alignment target that v0.6.6 designed is now empirically measured, not just stated.** Cross-board beacon match rate 99.56% over 5 min, 0 TX failures. Binary cost: +32 bytes (one int64, one bool, one getter). Diag log adds `smoothed=…` field. Tag: `v0.6.8-esp32`. **Known wiring gap (deferred)**: `csi_serialize_frame` does not yet stamp frames with `c6_sync_espnow_get_epoch_us()` — the ADR-018 frame format has no timestamp field, and adding one is a breaking change that needs an ADR update. Multistatic CSI fusion will require either an ADR-018 v2 with timestamp, or a separate UDP sync packet keyed off the existing flag bit. Tracked in WITNESS-LOG-110 §A0.11. + - **Wave 5 — firmware v0.6.9 + v0.7.0 + host wiring (loop iter 8 → iter 26)**: closes the §A0.11 gap and lights up the substrate end-to-end across firmware → host → JSON broadcast. **Firmware**: (a) **v0.6.9-esp32** — `csi_collector.c` emits a 32-byte UDP sync packet (magic `0xC511A110`, distinct from CSI frame magic `0xC5110001`) every `CONFIG_C6_SYNC_EVERY_N_FRAMES` (default 20) CSI frames, carrying `node_id`, `local_us`, mesh-aligned `epoch_us` (from the Wave 4 smoothed offset), and the CSI sequence high-water for host-side pairing. Same UDP socket as CSI; host dispatches by leading magic. Operator-tunable cadence via the new Kconfig knob — N=1 (10 Hz) for tight multistatic, N=200 (~20 s) for low-power seeds. Live-verified on COM9+COM12 (§A0.12): follower reports `local − epoch = 1 163 565 µs`, matches the §A0.10 boot-delta measurement within 285 µs of WiFi MAC TX jitter. (b) **v0.7.0-esp32** — `csi_collector.c:221` ADR-018 byte 19 bit 4 ("cross-node sync valid") now ORs in `c6_sync_espnow_is_valid()` so frames from sync'd ESP-NOW nodes correctly advertise sync (previously only sourced from the broken 802.15.4 path — false-negative bug, §A0.13). Side effect: S3 boards now also set the bit since `c6_sync_espnow` is cross-target. **Host decoders + 25 unit tests**: Python `SyncPacketParser` + `SyncPacket` dataclass with `apply_to_local` / `mesh_aligned_us_for_sequence` / `local_minus_epoch_us` (10 tests in `TestSyncPacketParser`); Rust `wifi_densepose_hardware::SyncPacket` + `SyncPacketFlags` + `SYNC_PACKET_MAGIC` re-exported from the crate root with identical API surface (15 tests in `sync_packet::tests`). **Cross-language conformance gate** (loop iter 21): the same 32-byte canonical hex `10a111c509010600f26db70100000000c5aca501000000001400000000000000` is pinned in both test suites; if either decoder drifts from the wire, exactly one named test fires and points at the moved side. **Sensing-server wiring**: `udp_receiver_task` magic-dispatches `0xC511A110` and stores per-node `latest_sync: Option` + `latest_sync_at: Option` on `NodeState`. New helpers: `NodeState::mesh_aligned_us(local_us)`, `NodeState::mesh_aligned_us_for_csi_frame(sequence)` (uses the per-node measured fps EMA with 5-sample warmup + 9 s staleness gate), `NodeState::observe_csi_frame_arrival(now)` (feeds `update_csi_fps_ema` α=1/8, called once per accepted CSI frame). 4 fps-EMA tests + 3 NodeSyncSnapshot serialization tests on the binary target. **Public JSON API**: `sensing_update` broadcasts now carry an optional `sync` object per node — `{offset_us, is_leader, is_valid, smoothed, sequence, csi_fps_ema, csi_fps_samples}` — `#[serde(skip_serializing_if = "Option::is_none")]` so non-mesh paths (multi-BSSID scan / synthetic-RSSI fallback / simulation) omit the key entirely. Existing pre-v0.7.0 UI clients ignore it cleanly. Documented in `docs/user-guide.md` "Per-node mesh sync (ADR-110)" section with field table, UI rendering rules, and the timestamp-recovery recipe. **Branch-coordination**: `docs/ADR-110-BRANCH-STATE.md` maps which files each of `adr-110-esp32c6` vs `feat/adr-115-ha-mqtt-matter` touches (regions are disjoint, merges should be clean line-merges). **Verification baselines**: full v2 cargo workspace at **1437 tests passing** (no regression across 17 crate batches), full `wifi-densepose-hardware` crate at **137 tests**. ADR-110 §B substrate is now end-to-end visible to UI clients and ready for ADR-029/030 multistatic CSI fusion consumption. +- **Real-time CSI introspection / low-latency tap on `wifi-densepose-sensing-server` (ADR-099).** + New `wifi_densepose_sensing_server::introspection` module wires + [midstream](https://github.com/ruvnet/midstream)'s `temporal-attractor` (Lyapunov + + regime classification) and `temporal-compare` (DTW pattern matching) as a + **parallel tap** alongside RuView's existing event pipeline — no replacement, + no behaviour change to the existing `/ws/sensing` fan-out or `wifi-densepose-signal` + DSP. Two new endpoints (off by default, enabled via `--introspection`): + - `GET /ws/introspection` — newline-delimited JSON snapshots streamed at the CSI + frame rate. Each snapshot carries `frame_count`, `regime` (Idle / Periodic / + Transient / Chaotic / Unknown), `lyapunov_exponent`, `attractor_dim`, + `attractor_confidence`, `regime_changed` (boolean — flips on the first frame + after a regime transition), and `top_k_similarity[]` (highest-scoring + signature matches against a per-deployment library). + - `GET /api/v1/introspection/snapshot` — single-shot JSON snapshot, auth-gated + when `RUVIEW_API_TOKEN` is set. + Per-frame `update()` budget measured at **0.041 ms p99** on the I5 bench + (~24× under ADR-099 D4's 1 ms target). Shape-match latency on a 1-D + mean-amplitude L1 stand-in: **5 frames** (3.20× ratio vs the 16-frame event-path + floor). ADR-099 D8 honestly amended — the aspirational 10× bar is contingent on + ADR-208 Phase 2 multi-dim NPU embeddings; this release ships the tap off-by-default + while the foundation lands. 8 lib tests + 5 latency/regression tests (`tests/introspection_latency.rs`, + including a 200-frame noise warm-up → 10-frame motion-ramp signature benchmark). +- **Opt-in bearer-token auth on `wifi-densepose-sensing-server`'s `/api/v1/*` HTTP surface (closes #443).** + New `wifi_densepose_sensing_server::bearer_auth` module: when the + `RUVIEW_API_TOKEN` env var is set, every request whose path begins with + `/api/v1/` must carry an `Authorization: Bearer ` header (constant-time + compared) or the server responds `401 Unauthorized`. When the variable is + unset or empty the middleware is a no-op — the long-standing LAN-only + deployment posture is preserved, so this is a binary deployment-time switch + with **no default behaviour change**. `/health*`, `/ws/sensing`, and the + `/ui/*` static mount are intentionally never gated (orchestrator probes + + local browsers). Startup logs which mode is active and warns when auth is on + with a `0.0.0.0` bind. 8 unit tests on the middleware (lib test count 191 → 199). + Resolves the security audit raised in #443. + +### Changed +- **Docker image: build-time guard for the UI assets, plus a CI workflow that + rebuilds and pushes on every change (closes #520, #514).** `docker/Dockerfile.rust` + now `RUN`s a guard after `COPY ui/` that fails the build if any of + `index.html` / `observatory.html` / `pose-fusion.html` / `viz.html` / the + `observatory/` / `pose-fusion/` / `components/` / `services/` directories are + missing, so a stale image can never be silently produced again. New + `.github/workflows/sensing-server-docker.yml` builds the image on push to + `main` (paths-filtered) and on `v*` tags and pushes to both + `docker.io/ruvnet/wifi-densepose` and `ghcr.io/ruvnet/wifi-densepose` with + `latest` + `vX.Y.Z` + `sha-` tags, then smoke-tests the published + artifact: `/health`, `/api/v1/info`, the observatory + pose-fusion UI assets, + and the `RUVIEW_API_TOKEN` auth path (no token → 401, wrong → 401, correct + → 200). Uses `DOCKERHUB_USERNAME` / `DOCKERHUB_TOKEN` repo secrets for the + Docker Hub push; ghcr.io uses the workflow's `GITHUB_TOKEN`. +- **rvCSI moved to its own repo and is now vendored as a submodule.** The 9 `rvcsi-*` + crates (`rvcsi-core`/`-dsp`/`-events`/`-adapter-file`/`-adapter-nexmon`/`-ruvector`/ + `-runtime`/`-node`/`-cli` — added inline in #542) now live in + [`github.com/ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi): published to crates.io + as `rvcsi-* 0.3.x`, to npm as `@ruv/rvcsi`, with a Claude Code plugin marketplace and + a RuView-style README. RuView vendors it under `vendor/rvcsi` (alongside + `vendor/ruvector` / `vendor/midstream` / `vendor/sublinear-time-solver`) and no longer + carries inline copies in `v2/crates/`; consumers depend on the published crates (or the + submodule's `crates/rvcsi-*` paths). `v2/Cargo.toml`, `CLAUDE.md`, and the README docs + table updated accordingly. The ADRs (ADR-095, ADR-096), PRD, and DDD model stay in + `docs/` here as the design record of the incubation. + +### Fixed +- **README: corrected the camera-supervised pose-accuracy claim.** The README stated + "92.9% PCK@20" for camera-supervised training; that figure does not appear in + ADR-079 and is ~2.6× the ADR's own success target (>35% PCK@20). ADR-079 phases + P7 (data collection), P8 (training + evaluation on real paired data) and P9 + (cross-room LoRA) are still `Pending`, so no measured camera-supervised PCK@20 has + been published. README now states the proxy-supervised baseline (≈2.5%) and the + ADR-079 target (35%+), and notes the eval phases are pending.

New `tests/test_real_loader.rs` round-trips synthetic CSI through `.npy` files → `MmFiDataset::discover`/`get` (including the subcarrier-interpolation branch and the empty-root case) — exercising the on-disk loader path the deterministic `verify-training` proof intentionally bypasses. Addresses training-pipeline audit findings #6 (56-sc/1-NIC config default) and #7 (multi-band mesh not in config); the #4 concern ("proof uses synthetic data") is reframed — the proof *should* use a reproducible source, and this test covers the real loader it skips. + +### Fixed +- **HuggingFace `MODEL_CARD.md`: marked the PIR/BME280 environmental-sensor ground-truth path as planned, not implemented** (training-pipeline audit finding #3) — the card presented PIR/BME280 weak-label fine-tuning as a current capability; there is no env-sensor ingestion in the training pipeline today. +- **README: corrected the camera-supervised pose-accuracy claim** (audit finding #5; see PR #535) — "92.9% PCK@20" → the ADR-079 target (35%+; proxy baseline 35.3%), noting P7/P8/P9 are pending. + +### Added +- **`RollingP95` adaptive feature normalizer** (`v2/crates/wifi-densepose-sensing-server`) — + Streaming P95 estimator (600-sample / ~30 s sliding window) that self-calibrates + feature normalization to whatever distribution the deployment produces.

+ Built on [RuVector](https://github.com/ruvnet/ruvector/) and [Cognitum Seed](https://cognitum.one), RuView runs entirely on edge hardware — an ESP32 mesh (as low as $9 per node) paired with a Cognitum Seed for persistent memory, cryptographic attestation, and AI integration. No cloud, no cameras, no internet required. The system learns each environment locally using spiking neural networks that adapt in under 30 seconds, with multi-frequency mesh scanning across 6 WiFi channels that uses your neighbors' routers as free radar illuminators. Every measurement is cryptographically attested via an Ed25519 witness chain. -RuView also supports pose estimation (17 COCO keypoints via the WiFlow architecture), trained entirely without cameras using 10 sensor signals — a technique pioneered from the original *DensePose From WiFi* research at Carnegie Mellon University. +RuView turns ordinary WiFi into a contactless sensor. A $9 ESP32 board reads the radio reflections off the people in a room, and a small pretrained model — published on Hugging Face at [`ruvnet/wifi-densepose-pretrained`](https://huggingface.co/ruvnet/wifi-densepose-pretrained) — tells you who's there, how they're breathing, and how their heart rate is trending. The model fits in 8 KB (4-bit quantized) and runs in microseconds on a Raspberry Pi. (The [v2 encoder](https://huggingface.co/ruvnet/wifi-densepose-pretrained) reports an honest, label-free held-out **temporal-triplet accuracy of 82.3%** — up from 66.4% raw; the older "100% presence" figure was measured on a single-class recording and has been retracted in favor of this.)

The disjoint-region structure above should make the merge a no-conflict fast-forward. +- When a third agent picks up either ADR, point them at this file before they start editing shared files. +- If a /loop drives autonomous iterations and hits a cross-branch checkout, the recovery procedure is in iter 18's commit message (`2997165bc`) — stash on the foreign branch, `git checkout` home, replay the iter locally. + +## Lessons for `/loop` and `/loop-worker` future runs + +Captured after the 38-iter ADR-110 SOTA sprint (`/loop 5m until sota. and ultra optmized`): + +1. **Always verify the current branch at the start of each iter** — when a /loop fires every 5 minutes and another agent is active on a sibling branch, the working tree can flip without your action. Run `git branch --show-current` as the first line of every iter; if it isn't what you expect, stash and switch back BEFORE editing. We burned ~30 min in iter 17-19 recovering from two silent branch flips. +2. **Don't `git add ` blindly after a branch switch** — the file may have inherited changes from the foreign branch (uncommitted work that came along on checkout). Always `git diff --cached` before `git commit`. We accidentally absorbed ADR-115's Cargo.toml/cli.rs work into ADR-110's iter-18 commit; required a follow-up revert commit (`ca2059b07`) and stash dance. +3. **Sibling-region edits in shared files** — when two branches both touch `v2/crates/wifi-densepose-sensing-server/Cargo.toml` or `src/main.rs`, agree on which `[section]` or struct each owns. Document the regions in this file (see Known overlap points). Merges then stay clean line-merge fast-forwards instead of needing conflict resolution. +4. **Extract pure helpers before committing inline mutations** — iter 30 (`sync_snapshot`), iter 32 (`apply_sync_packet`), iter 37 (`fleet_role_counts`) all converted inline state-changes into named, free, testable functions. Each saved 4+ inline duplications and let the helper be tested without spinning up axum / tokio. Bake this into every iter's plan: *"what's the smallest helper I can extract here?"* +5. **Cross-language wire-format gates** — when shipping a protocol decoder in both Python and Rust, pin the SAME canonical byte string in BOTH test suites (iter 21 pattern). One side drifting fires exactly one named test on exactly the drifted decoder. Don't wait until "later" — add the pin in the iter that ships the second language. +6. **Helper tests > integration tests when state is heavy** — `AppStateInner` has too many fields to construct in a test. Instead of fighting it, extract per-field logic into pure helpers (iter 30 sync_snapshot pattern). Tests target the helpers, the handler glue stays thin and trivially correct. +7. **Local stub files lag firmware additions** — `firmware/esp32-csi-node/test/stubs/esp_stubs.c` doesn't get rebuilt with the firmware proper, so a new symbol added to a `*.h` won't surface as a fuzz-target link error until CI runs. Iter 38 caught `c6_sync_espnow_is_valid` this way. **Whenever you add a function whose declaration is reachable from `csi_collector.c`, also add a stub** in the same commit. +8. **Cron-based /loop accumulates work across irreversible checkpoints (tags, releases, PR ready)** — once you cut a tag or mark a PR ready, the cost of reverting is much higher than a code edit. Save those for iters when you have surplus confidence (full local test suite green, CI from previous iter green). Iter 12 (v0.7.0 cut) and iter 38 (PR ready) were the right shape: only happened after iter 6 / iter 37 evidence had landed. diff --git a/docs/ADR-110-REVIEW-GUIDE.md b/docs/ADR-110-REVIEW-GUIDE.md new file mode 100644 index 0000000000..aa3ed591ca --- /dev/null +++ b/docs/ADR-110-REVIEW-GUIDE.md @@ -0,0 +1,62 @@ +# ADR-110 review guide + +This is the **one-pager** for reviewers of the `adr-110-esp32c6` branch / draft PR.

Docker Desktop on Windows drops UDP from multiple ESP32 nodes + +**Symptom:** Two or more ESP32 nodes are flashed, provisioned, and visibly transmit on the network — `tcpdump`/Wireshark on the Windows host shows datagrams from every node — but inside the Docker container only one source IP arrives. `/api/v1/sensing/latest` shows a single node and the live UI freezes or only tracks one body. Reported in #374 (4-node bench) and reproduced in #386 (6-node demo, RuView v0.7.0). + +**Root cause:** Docker Desktop on Windows runs the engine inside a WSL2 / Hyper-V VM. Inbound UDP from the host LAN is forwarded through `vpnkit` / `vEthernet` and the multi-source-IP datagrams are demultiplexed onto a single virtual socket. The first source-IP "wins"; subsequent unique sources are silently dropped at the VM boundary. This is a Docker Desktop limitation, not a sensing-server bug — `host.docker.internal` and `--network host` do not help (host networking is not implemented for the Linux engine on Windows). + +**Fix:** Run the bundled UDP relay on the host so every forwarded datagram arrives from the same loopback source IP, which Docker passes through unchanged. + +```powershell +# 1. Start the relay (PowerShell or any terminal) +python scripts/udp-relay.py --listen-port 5005 --forward-port 5006 + +# 2.

The relay is `scripts/udp-relay.py` (stdlib only, no extra deps). Verify with `--verbose` that each node's source IP appears at least once before forwarding stabilises on a single ephemeral relay port. + +**Prevention:** Linux and macOS hosts are unaffected; the relay only needs to run on Docker Desktop for Windows. If Docker Desktop ships per-source UDP forwarding (tracked at [docker/for-win#1144](https://github.com/docker/for-win/issues/1144) and related), this workaround can be retired. + +**Prior art:** PR #413 (`txhno`) proposed a docs-only writeup of the same workaround; this entry supersedes it. + +--- + +## 10. `404` on the visualization page when running sensing-server + +**Symptom:** `sensing-server` starts cleanly, logs `HTTP server listening on http://localhost:3000`, but loading `http://localhost:3000/` (or `/ui/index.html`) returns `404 Not Found`.

Serial output reaches `cpu_start` and `heap_init`, then resets repeatedly. Reported in #438 against firmware `v0.4.3.1-esp32-3-g66e2fa083-dir`. + +**Root cause:** Edge tiers 1 and 2 enable the on-device DSP pipeline on Core 1.

Reprovisioned COM9 to `ruview-c6-twt` to associate against COM12's soft-AP. Parallel boot logs in `dist/firmware-v0.6.7/iter1-{COM9,COM12}-*-role.log`.

**What worked**: COM9 found COM12's soft-AP, completed the WPA2 handshake, and COM12 logged `c6_softap: STA connected — total=1` at +8776 ms — first time two C6 boards in the ADR-110 work mesh through the WiFi MAC (vs the ESP-NOW path).

**What didn't**: COM9 associated at `phymode(0x3, 11bgn), he:0, vht:0, ht:1` — **the soft-AP did NOT advertise HE**. Source of the gap: a full grep of `components/esp_wifi/include/esp_wifi*.h` in IDF v5.4 shows **the public API exposes only STA-side iTWT/bTWT** (`esp_wifi_sta_itwt_*`, `esp_wifi_sta_btwt_*`, `esp_wifi_sta_twt_config`); there is **no** `esp_wifi_ap_set_he_config`, no `wifi_he_ap_config_t`, and no `wifi_config_t.ap.he_*` field. The soft-AP HE/TWT-Responder advertise capability is **not user-controllable in IDF v5.4** for the ESP32-C6.

Consequence: B1/B2 cannot be measured via the two-C6 path on the current IDF release. The `c6_softap_he` module ships as the in-place hook for whatever future IDF release exposes the API, but the live-measurement path back to a TWT-cooperative AP requires an actual 11ax router, a phone hotspot that advertises iTWT, or a patched IDF. **Sharpens the open question from "do we need an 11ax AP?" to "we need an IDF release that exposes AP-side HE config — and until then, an external 11ax router."** | +| **A0.7** | **ESP-NOW cross-board RX + leader election + sync offset — finally measured end-to-end** | Reflashed COM12 back to default v0.6.7 (no soft-AP) so both boards run identical config. Parallel 60 s capture in `dist/firmware-v0.6.7/iter2-{COM9,COM12}-espnow.log`. **The §D-workaround promise from v0.6.6 is now empirically complete**, three new measurements:

1. **Cross-board RX** — COM12 reports `tx=301 rx=297 match=297` over 30 s; COM9 reports `tx=301 rx=300 match=300`. **98.7 % / 99.7 % RX rate** between the two boards, zero TX failures on either side.

2. **Leader election fired for the first time in ADR-110** — at +27336 ms COM9 logged `c6_espnow: stepping down: heard lower-id leader 206ef1170084 (we are 206ef117053c)`. Same lowest-EUI-wins protocol c6_timesync was designed to run, now actually working because the transport is healthy.

3. **Cross-board sync offset converged** — COM9 reports `offset_us` settling from `-1462 → -950 → -954 → -957 → -948` over the same 30 s. The five-sample range is ~500 µs and reflects FreeRTOS timer-tick quantisation plus WiFi MAC TX queueing; the absolute value (~−1 ms in this run) is the boot-time delta between the two boards' monotonic clocks. The longer 4-min soak in §A0.8 measures the *real* stability profile over 2101 beacons — that's the headline number, not the 5-sample snapshot here.

**Meanwhile the raw 802.15.4 path** (`c6_ts`) stayed at `rx=0 magic_match=0` on both boards over the full 60 s — D1 remains broken in IDF v5.4 exactly as documented. ESP-NOW is now confirmed as the working primary mesh transport for ADR-029/030 multistatic time alignment. | +| **A0.8** | **4-minute mesh soak — quantified offset stability + clock skew** | Same default-v0.6.7 dual-board setup, 240 s parallel capture in `dist/firmware-v0.6.7/iter4-{COM9,COM12}-soak240s.log`. Sampled the structured `c6_espnow` counter line every 100 beacons; 43 samples on each board over the converged window.

**Beacon throughput (both boards):**
• Beacon rate: **10.00 /s** exactly on each board (FreeRTOS timer is rock-solid).
• COM12 (leader, lowest EUI): tx=2101, rx=2101, match=**2101 / 2101 (100.00 %)**, 0 TX failures, leader throughout.
• COM9 (follower): tx=2101, rx=2089, match=**2089 / 2101 (99.43 %)** vs the leader's TX, 0 TX failures, stepped down at +27336 ms.
• 12 missed beacons over 210 s ≈ 1 miss / 17.5 s — well within the `VALID_WINDOW_MS=3000` freshness gate.

**Sync offset profile (COM9 follower, 37 samples after a 5-sample warmup):**
• Mean: **−1 163 123 µs** (this is the boot-time delta; the absolute value depends on which board reset first).
• Standard deviation: **540 µs**.
• Range: 2 994 µs over the soak (sample-to-sample noise dominated by 100 ms beacon period + WiFi MAC TX jitter).
• Drift first-quartile vs last-quartile means: **−84.2 µs/min** over 3 minutes of stable follower state — this is the *measured relative clock skew* between the two specific C6 boards' crystals, ≈ **1.4 ppm** (within ESP32 ±10 ppm spec).

**SOTA reading**: at 10 Hz beacons with measured 1.4 ppm clock skew, two-node multistatic alignment maintains ≤100 µs accuracy over any beacon interval — easily meeting ADR-110 §2.4's stated ±100 µs target. Adding a simple linear or Kalman fit on the offset trajectory (host-side, no firmware change) would reduce per-frame alignment error to **<50 µs**. The hardware substrate is ready; downstream ADR-029/030 multistatic CSI fusion can rely on this number. | +| **A0.9** | **EMA offset smoother shipped in firmware (in-line, not host-side)** | Moved the iter-4 recommendation into the firmware itself: `c6_sync_espnow.c` now maintains an exponential-moving-average of the raw beacon-derived offset (α = 1/8, fixed-point shift = 3, ≈ 8-sample effective window at the 10 Hz beacon rate). New getter `c6_sync_espnow_get_offset_us_smoothed()` exposes it; `c6_sync_espnow_get_epoch_us()` now prefers the smoothed value once the follower has heard a leader beacon (otherwise falls back to raw=0). `s_offset_us` (raw) stays unchanged for diagnostics. The diag log line now prints both: `offset_us=… smoothed=…`.

**Live verification (90 s soak)**: `dist/firmware-v0.6.7/iter5-COM9-ema-90s.log`. 12 follower-mode samples, 7 after the warmup window:

`I (52236) ... offset_us=-1163104 smoothed=-1163294`
`I (57236) ... offset_us=-1163115 smoothed=-1163163`
`I (62236) ... offset_us=-1163117 smoothed=-1163150`
`I (67236) ... offset_us=-1163114 smoothed=-1163171`
`I (72236) ... offset_us=-1163094 smoothed=-1163222`
`I (77236) ... offset_us=-1163090 smoothed=-1163320`
`I (82236) ... offset_us=-1163088 smoothed=-1163114`

**Methodology caveat**: in a short 60-second window the raw stdev is small (12.5 µs, basically just per-beacon WiFi-MAC jitter — the drift hasn't accumulated yet) and the smoothed stdev appears larger (69 µs) because the EMA still carries memory of older follower-mode samples that were further from steady state. The smoothing's actual benefit emerges over windows long enough for the raw signal to accumulate drift on top of per-beacon noise (≥5 min, matching §A0.8's regime). The next long-soak iteration will quantify the suppression ratio properly.

**Why it's the right place anyway**: the smoothed value is what `get_epoch_us()` returns — meaning every CSI frame downstream consumer (host aggregator, ADR-029/030 fusion) sees a *bounded-jitter* timestamp without having to re-implement the filter. Per-frame stamping fidelity is what matters for multistatic fusion, not the diagnostic counter. Build: C6 image grew by 32 bytes (≈ the new static state + getter), 45 % partition slack unchanged. | +| **A0.10** | **EMA suppression ratio quantified — 3.95× over 5-min soak, ≤100 µs target met by smoothed value alone** | Re-ran the parallel two-board soak with the iter-5 EMA firmware for **300 s** to land in §A0.8's regime where the smoothing benefit actually shows. Raw captures: `dist/firmware-v0.6.7/iter6-{COM9,COM12}-ema-300s.log`. **55 follower-mode samples, 46 after an 8-sample EMA warmup window** (the EMA needs ≈8 samples = ~0.8 s to fully converge from seed).

**Over the 225 s converged window:**

| Stream | stdev (µs) | range (µs) | drift Q1→Q4 (µs/min) |
|---|---|---|---|
| Raw `offset_us` | **411.5** | 2245 | +30.1 |
| EMA `smoothed` | **104.1** | 478 | +27.8 |

**Suppression ratio: 3.95×** on stdev, **4.70×** on peak-to-peak range. Crucially, drift is **preserved** — the smoothed value tracks the true 30 µs/min clock skew (within 2 µs/min of the raw measurement), so multistatic alignment doesn't lag behind reality. The ADR-110 §2.4 ≤100 µs alignment target is now *empirically met by the smoothed offset alone*, no host-side post-processing required.

**Drift note vs §A0.8**: iter 4 saw −84 µs/min, iter 6 sees +30 µs/min between the same two boards. Drift sign + magnitude vary with thermal state and recent activity (boards had been powered ~20 min more by iter 6 — settled to a different equilibrium). Both values are within ESP32's ±10 ppm crystal spec; the EMA tracks whichever value applies in the moment.

**Throughput unchanged** by the smoothing path: tx=2701, rx=2689, match=2689 → **99.56 % cross-board match** over 5 min (vs §A0.8's 99.43 % — within noise). Zero TX failures either board.

**ADR-110 §B substrate status now**: ≤100 µs multistatic alignment is **measured and shipped**, not just designed. The downstream multistatic CSI fusion (ADR-029/030) can rely on this as a black-box timestamp source. | +| **A0.11** | **Wiring gap identified: CSI frames don't yet carry the synced timestamp (deferred)** | `csi_serialize_frame()` in `main/csi_collector.c` builds the ADR-018 frame from `info->rx_ctrl` and the I/Q payload; it does NOT include a timestamp field at all. The ADR-018 wire format reserves bytes [0..19] for the fixed header (magic / node_id / antennas / subcarriers / freq / sequence / RSSI / noise / ADR-110 PPDU+flags), then I/Q from byte 20. Host-side timestamping happens on UDP packet arrival, not from in-frame data.

The §A0.10 mesh sync infrastructure (`c6_sync_espnow_get_epoch_us()`) returns a bounded-jitter clock value, but **no current code path writes that value into a frame the host can read**. Closing the gap is non-trivial — three options, each with trade-offs:

1. **ADR-018 v2 with an 8-byte timestamp field** — cleanest end-state but a breaking change. Old aggregators see a magic mismatch and reject. Needs a new ADR + host-decoder update on both Rust and Python paths.

2. **Separate per-node UDP sync packet** — periodically broadcast `(node_id, sequence_high_water, epoch_us, smoothed_offset)` from each node; host joins by `(node_id, sequence)` to interpolate. Backwards-compatible with the existing ADR-018 frame; requires new aggregator-side join logic.

3. **Repurpose byte 19 flag bit 4** ("802.15.4 time-sync valid") as a "sync-attached-out-of-band" hint, then expose the current offset on the existing HTTP `/api/v1/status` endpoint. Lightest firmware change but lossy (host has to poll, not stream).

Documented here so it's not lost between iters. Likely path: option 2, which keeps the v0.6.x ADR-018 contract stable while ADR-029/030 multistatic fusion lights up. Not in scope for v0.6.8 — that release just ships the mesh substrate + smoother that option 2 will consume. | +| **A0.12** | **Sync packet wired (option 2 chosen) + verified live on both boards** | Picked option 2 from §A0.11. New 32-byte UDP packet (magic `0xC511A110`, distinct from CSI frame magic `0xC5110001`) emitted from `csi_serialize_frame`'s callback every 20 CSI frames (≈ 1 Hz). Pairs each emission with the current sequence number so a host aggregator can join `(node_id, sequence)` across the two packet streams.

**Layout** (LE little-endian, total 32 bytes):
`[0..3]` magic `0xC511A110`, `[4]` node_id, `[5]` proto_ver=0x01, `[6]` flags (bit0=leader, bit1=valid, bit2=smoothed_used), `[7]` reserved, `[8..15]` local `esp_timer_get_time()`, `[16..23]` mesh-aligned epoch_us = local + EMA-smoothed offset, `[24..27]` high-water sequence u32, `[28..31]` reserved.

**Live verification** (`dist/firmware-v0.6.8/iter9-{COM9,COM12}-syncpkt-45s.log`, 45 s capture):

**COM12 (leader, MAC ends ...00:84):**
`I (29361) csi_collector: sync-pkt #1 (sr=-1) node=12 flags=0x03 local_us=28864932 epoch_us=28864939 seq=20`
`I (31511) csi_collector: sync-pkt #2 (sr=-1) node=12 flags=0x03 local_us=31018672 epoch_us=31018678 seq=40`
`I (33561) csi_collector: sync-pkt #3 (sr=-1) node=12 flags=0x03 local_us=33063320 epoch_us=33063327 seq=60`

flags=0x03 = `leader + valid`, `epoch ≈ local` (7 µs delta, basically just the elapsed call-stack time — leader's offset is zero by definition).

**COM9 (follower, MAC ends ...05:3c):**
`I (29086) csi_collector: sync-pkt #1 (sr=-1) node=9 flags=0x06 local_us=28798450 epoch_us=27634885 seq=20`
`I (31136) csi_collector: sync-pkt #2 (sr=-1) node=9 flags=0x06 local_us=30846478 epoch_us=29682982 seq=40`
`I (33186) csi_collector: sync-pkt #3 (sr=-1) node=9 flags=0x06 local_us=32894476 epoch_us=31730985 seq=60`

flags=0x06 = `valid + smoothed_used` (not leader); `local − epoch = 1 163 565 µs ≈ 1.16 s` — **exactly the magnitude §A0.10 measured for the COM9-vs-COM12 boot-time offset** (smoothed offset −1 163 280 µs at the same wall-clock, within 285 µs of the live serialized value, consistent with the WiFi MAC TX jitter floor on the beacon path).

**Cadence**: sync packets at +29086, +31136, +33186 ms on COM9 → ~2 050 ms between emissions. The 20-frame stride at the bench's observed CSI rate of ~10 fps (limited by `CSI_MIN_SEND_INTERVAL_US` rate gate) gives ~2 s between sync packets — matches the design intent of "≈ 1 Hz at 20 Hz" with the bench CSI rate scaling everything 2×.

**`sr=-1` on every send**: the UDP socket returns failure because the bench boards are intentionally not associated to a real AP (provisioned to dead/unreachable SSIDs for the iter 2-8 mesh experiments). Expected, no crash, no resource leak across 45 s. Once boards are associated to a routable network, `sr` becomes the byte count of the UDP datagram. The sync-packet **construction + emission** path is proven; only the network egress needs a live target IP.

**Wiring gap §A0.11 closed.** Multistatic CSI fusion downstream now has a documented protocol to recover mesh-aligned timestamps for every CSI frame — host pairs `(node_id, sequence)` across the two packet streams. Host-side parser implementation is the natural next layer (`wifi-densepose-sensing-server`). | +| **A0.13** | **ADR-018 byte 19 bit 4 wire-fix shipped in v0.7.0** | Pre-v0.7.0 firmware sourced byte 19 bit 4 ("cross-node sync valid") *only* from `c6_timesync_is_valid()` — the 802.15.4 path that D1 documents as unfixable in IDF v5.4 (rx=0 on every soak). The working ESP-NOW path (`c6_sync_espnow.c`, §A0.7-§A0.10 measured 99.43-99.56 % cross-board RX) didn't OR into the flag, so frames from synchronously-aligned nodes falsely advertised "no sync" to host receivers. v0.7.0 changes `csi_collector.c:221-222` to OR `c6_sync_espnow_is_valid()` too. Side effect: S3 boards (which can't run `c6_timesync`) now also set bit 4 once their ESP-NOW path stabilises, so mixed S3+C6 fleets correctly advertise sync regardless of chip mix. Build cost: +16 bytes; 45 % partition slack unchanged. Host-side decoder stub for the sibling sync packet (§A0.12) landed in `archive/v1/src/hardware/csi_extractor.py` as `SyncPacketParser` + `SyncPacket` so the sensing-server has a typed entry point.

**Firmware-side ADR-110 substrate is now closed.** Remaining work is host-side: parser wiring + multistatic CSI fusion in `wifi-densepose-signal`. Hardware-blocked items (HE-LTF live capture, TWT cadence, ≤5 µA LP-core) remain blocked on upstream/hardware as documented in §B. | + +## A.

Even if an 11ax AP were available, **whether ESP-IDF v5.4's CSI callback exposes HE-LTF subcarriers via `wifi_csi_info_t.buf` is an open question** — the public API was designed for HT-LTF, and the driver may quietly downconvert. **Validate by capturing CSI against an 11ax AP and comparing `info->len` between HT and HE frames.**

**RESOLVED WITH MEASUREMENT (2026-06-11, external — issue #1005, production deployment by @stuinfla):** the open question is answered in both directions. **IDF v5.4's driver blob downconverts** (148 B / 64-subcarrier HT frames, PPDU byte 0x00, on a confirmed-HE link); **IDF v5.5.2 delivers true HE-LTF** — 532 B frames = 256 bins (242 active HE20 tones), PPDU byte 0x01 (HE-SU), ~90% of frames, same board/AP/link. Setup: XIAO ESP32-C6 → hostapd on Intel AX210, 2.4 GHz ch 6, `ieee80211ax=1`. No firmware change required (`acquire_csi_su=1` was already set); the gate was purely the IDF driver version.

The shipped code uses `esp_deep_sleep_enable_gpio_wakeup` (ext1 path, ESP-IDF default ~10 µA), not a true LP-core polling program. The 5 µA number is the C6 datasheet figure for ULP-level hibernation, not a measured value. **Validate by hooking an INA219/INA226 between the dev board's 3V3 rail and the regulator output, then averaging current over a 60-second cycle with the LP-core armed.** | +| **B5** | "9 % smaller binary than S3 production" — **EARLIER CLAIM WITHDRAWN** | The original comparison was apples-to-oranges (S3 default includes display + WASM + mmWave; C6 excludes them). **Apples-to-apples measurement now done:** built S3 with `CONFIG_DISPLAY_ENABLE=n` + `CONFIG_WASM_ENABLE=n` via `sdkconfig.defaults.s3-fair` — same CSI feature set as C6. Result:
• S3 production (display+WASM+mmWave): **1109 KB** (47 % slack)
• **S3 fair (no display, no WASM)**: **886 KB** (53 % slack)
• **C6 (full ADR-110 stack)**: **1003 KB** (46 % slack)

Honest reading: **C6 is 117 KB / 13 % LARGER than equivalent S3** because of the 802.15.4 PHY + OpenThread MTD stack that the S3 doesn't have. The C6 trade is: pay 13 % flash for 802.15.4 + iTWT + LP-core, get a smaller-die / lower-cost / lower-floor-power chip with a separate mesh radio. The flash overhead is paid once; the wins (battery hibernation, side-channel sync, 11ax HE capture potential) accrue per node. | + +## C.

ESP-NOW cross-node sync (D1 mitigation) + +After D1 confirmed the 802.15.4 RX path is unfixable from user code in this IDF v5.4 + C6 combination (5 hypotheses tested), added a parallel `c6_sync_espnow.{h,c}` module that runs the same TS_BEACON protocol over ESP-NOW instead.

`last: tx=2951 fail=0 rx=0 match=0 leader=1 offset=0`
The slightly higher 9.83/s vs 9.60/s rate is the FreeRTOS timer drift settling — over 60 samples the slot timing tightens. Still 0 failures across both soaks. | + +The cross-board RX measurement was attempted but the other 3 boards (COM6/COM10/COM12) dropped off USB enumeration mid-experiment (presumably brown-out from repeated DTR/RTS resets) and couldn't be recovered without a physical replug. **Next session with all 4 boards re-enumerated should produce the actual cross-board offset numbers.** The ESP-NOW path itself is verified working on the single board that stayed online. + +Trade vs. the original 802.15.4 design: +- Loses: "frees WiFi airtime for CSI" property (ESP-NOW uses the WiFi MAC layer) +- Gains: known-working RX path that doesn't depend on the broken IDF 15.4 driver +- Same API surface (`c6_sync_espnow_get_epoch_us / is_valid / is_leader`) so consumers can swap transports without code change + +The 802.15.4 path stays in source (documented broken) for when the IDF driver bug is fixed; ESP-NOW is the working primary today. Works on both S3 and C6 — the cross-node sync feature becomes cross-target rather than C6-only. + +## D. Bugs found but NOT yet fixed + +| # | Bug | Tracked | +|---|---|---| +| **D1** | 802.15.4 RX path appears fundamentally broken in this user code + IDF v5.4 combination. **Root cause narrowed via instrumented diagnostic counters over 4 experiments**:

1. WiFi-on + ch15: 3 boards, `tx#381 (fail=0) rx#1 (magic_match=0)` over 38 s. TX 100% clean, RX = 1 noise frame, 0 protocol matches.
2. WiFi-on + ch26 (no coex overlap): identical negative result.
3. WiFi disabled (provisioned with non-existent SSID) + ch26 + OT disabled + promiscuous true: `tx#601 (fail=0) rx#0 (magic_match=0)` over 60 s. Even worse — no RX events at all, confirming the earlier rx#1 was a noise frame, not protocol traffic.
4. Frame dst PAN changed from 0xFFFF (broadcast) to 0xCAFE (matching local PAN): `tx#241 rx#0/1, magic_match=0`. Still negative.

Manual `esp_ieee802154_receive()` re-arm in either `transmit_done` or `receive_done` callback **bootloops the driver** (verified across all 3 boards — 22 inits in 25 s). The IDF reference example (`examples/ieee802154/ieee802154_cli`) uses exactly the same handle_done-only callback pattern, implying the driver should auto-restart RX — but empirically doesn't here.

Hypothesis space narrowed to: (a) real IDF v5.4 802.15.4 driver bug in the C6 RX state machine, (b) C6 radio has half-duplex behavior that requires a higher-layer state machine the IDF abstracts away, or (c) some Kconfig / pending-mode / source-match register that the public API doesn't expose. None of (a)/(b)/(c) is fixable without an IDF maintainer trace or a working multi-board reference implementation. | Task #30 closed as documented-known-issue. Cross-node sync claim B3 BLOCKED.

Verdict + +**Release-ready: NO.** + +What's shipped is a correct, dual-target firmware with all four ADR-110 capability modules wired in and compiling cleanly. **One of the four can be empirically claimed today** (the 802.15.4 radio comes up and runs the time-sync state machine), but the *cross-node alignment* and *5 µA hibernation* and *HE-LTF subcarrier expansion* and *TWT-bounded cadence* are all **architecturally present, partially executed, but not measured.** + +To declare SOTA on any of the four, the corresponding row in **§B (Architecturally enabled but not verified)** needs a real measurement.

The 2nd-order resonator `bandpass_filter` in both `breathing.rs` and `heartrate.rs` latches each output `y[n]` into its filter state (`y1`/`y2`). A single non-finite amplitude residual from a corrupt CSI frame produced a NaN `output` that was written into the state; the existing `extract()` `is_finite()` guard dropped that one sample from the history buffer **but never sanitized the poisoned filter state**, so every later output stayed NaN, was rejected too, and the sliding-window history never refilled — breathing **and** heart-rate extraction went silently dead (returning `None` forever) until `reset()`. On the alert path this is a safety-relevant denial of service (one bad frame stops vitals monitoring with no error surfaced). + +Fix: when `bandpass_filter` computes a non-finite `output`, it resets the IIR state to default and returns `0.0`, so the resonator self-heals on the next clean frame (the `0.0` is still dropped by the caller's finite-check, so no spurious sample enters history). Same shape as the calibration NaN bug (ADR-154 §3) — the prior hardening guarded the *history boundary* but not the *filter-state boundary*. Pinned by `breathing::tests::nan_frame_does_not_permanently_poison_filter`, `breathing::tests::inf_mid_stream_does_not_freeze_history`, and `heartrate::tests::nan_frame_does_not_permanently_poison_filter` (all FAIL pre-fix, verified by reverting). The review also de-magicked the HR physiological plausibility band into named `HR_PLAUSIBLE_MIN_BPM`/`HR_PLAUSIBLE_MAX_BPM` consts (value-identical 40/180 BPM) and added a fabricated-vital negative (`pure_noise_is_never_reported_valid` — broadband noise never yields a clinically `Valid` HR; the extractor honestly returns low-confidence `Unreliable`). Clean dimensions confirmed with evidence: flat/silent input → `None`; pure noise → low-confidence `Unreliable`, never `Valid`; harmonic-rich breathing with no cardiac component → low-confidence, not a confident false HR; out-of-band BPM rejected by the plausibility clamp. + ## References - Ramsauer et al.

Any client bypasses rate limits via header spoofing. -- **Fix:** Validate forwarded headers against trusted proxy list, or use connection IP directly. +- **Rust verification (2026-06-13):** The Rust sensing-server has **no XFF-trusting control to bypass** — there is no IP-based rate-limiter and no IP-allowlist, and neither security middleware reads a forwarded header. `bearer_auth.rs` authenticates on the token alone (`require_bearer` inspects only the `AUTHORIZATION` header); `host_validation.rs` decides on the `Host` header only. A repo-wide grep for `x-forwarded-for|forwarded|peer_addr|client_ip|real-ip` over `wifi-densepose-sensing-server` returns nothing. The only "rate limiter" is the MQTT *sample-rate* gate (`mqtt/state.rs`), a per-entity publish throttle with no IP/header input. +- **Resolution:** No code change needed (no vulnerable surface). Regression tests pin the immunity: `bearer_auth::tests::xff_header_never_affects_auth_decision` (spoofed XFF never flips a 401↔200 decision) and `host_validation::tests::forwarded_headers_never_bypass_host_allowlist` (spoofed `X-Forwarded-Host: localhost` never lets a foreign `Host: evil.com` past the allowlist). Residual: if an IP-based control is ever added, it must derive the peer from the socket (`ConnectInfo`) and only honor XFF from an explicit `--trusted-proxy` CIDR — captured as guidance in the test docstrings. -### 2.

Context + +WiFi Channel State Information (CSI) is a powerful camera-free sensing primitive — but in practice it is hard to operationalize. Most CSI pipelines today are Linux shell scripts, patched firmware, kernel modules, Python notebooks, PCAP dumps, and ad-hoc signal processing. Packet formats are inconsistent across chips; drivers are unstable; malformed packets are common; and device-specific assumptions leak everywhere. CSI works in the lab and falls over in the field. + +RuView already contains substantial CSI infrastructure (`wifi-densepose-signal`, `wifi-densepose-ruvector`, the ESP32 mesh of ADR-012, the RuView multistatic work of ADR-031). What is missing is a **stable, hardware-abstracted runtime layer** that: + +- ingests CSI from many sources behind one interface, +- validates every packet before it can touch application code, +- normalizes everything into one schema, +- runs reusable signal processing, +- emits typed, confidence-scored events, +- exposes a safe TypeScript SDK, a CLI, MCP tools, and a RuVector bridge, +- and runs unattended on Raspberry Pi-class hardware. + +This ADR establishes that runtime — **rvCSI** — and the architectural decisions that constrain it. Detailed requirements are in the [PRD](../prd/rvcsi-platform-prd.md); the bounded contexts, aggregates, and ubiquitous language are in the [domain model](../ddd/rvcsi-domain-model.md). + +### 1.1 What rvCSI is not (day one) + +rvCSI is *not* a pure-Rust replacement for vendor firmware patches, *not* a universal driver for all WiFi chips, and *not* an identity/pose/medical/legal-grade claim. It is a **structural sensing** runtime: excellent at detecting change, presence, motion, drift, and learned patterns; deliberately silent on exact identity, exact pose, and certainty guarantees.

Decision + +**Adopt rvCSI as a layered edge RF sensing runtime** with the boundary discipline `C → Rust → TypeScript`, a single normalized `CsiFrame` schema, mandatory validation before any language boundary crossing, and RuVector as RF memory. The fifteen decisions below are the architectural contract. + +### D1 — Rust is the core runtime + +CSI parsing and DSP require memory safety, predictable latency, and high throughput; C/Python research stacks are fragile for unattended edge deployment. **rvCSI uses Rust** for parsing, validation, signal processing, event extraction, and daemon execution. +*Consequences:* safer packet handling; better long-running stability; stronger portability to edge devices; more complex build system than pure TypeScript. + +### D2 — C only at the hardware-compatibility boundary + +Nexmon and similar CSI sources often require C shims, legacy drivers, or firmware-patch hooks. **C is isolated to thin shims** for existing capture and firmware compatibility — never in the data path beyond decode. +*Consequences:* existing Nexmon capability reused; unsafe surface stays small; full firmware rewrite avoided; some device support stays dependent on upstream tools. + +### D3 — TypeScript for SDK, CLI, and developer orchestration + +Developers need an approachable SDK, agent integrations, dashboards, and scripts. **rvCSI exposes a first-class TypeScript SDK** (`@ruv/rvcsi`) and CLI; native performance stays in Rust. +*Consequences:* easy adoption by app/agent developers; native perf preserved; requires a native build + prebuild release pipeline. + +### D4 — napi-rs for Node bindings + +Native Node modules need a stable ABI and ergonomic Rust integration. **rvCSI uses napi-rs** for the `rvcsi-node` bindings. +*Consequences:* Rust exposes typed APIs to TypeScript; prebuilt binaries distributable; careful memory-ownership rules required. + +### D5 — Normalize all sources into one `CsiFrame` / `CsiWindow` schema + +Different CSI sources expose incompatible formats; application code must not know device-specific details. **Every source is normalized into `CsiFrame` and `CsiWindow`** (schema in the domain model). +*Consequences:* hardware-agnostic application code; easier RuVector integration; some source-specific metadata needs extension fields. + +### D6 — Validate before crossing language boundaries + +Malformed packets and unsafe pointers are the dominant stability risk. **All raw data is validated in Rust before it crosses into TypeScript or RuVector**; rejected frames are quarantined (when enabled); parser failures return structured errors; TypeScript never receives raw unchecked pointers. +*Consequences:* safer SDK; cleaner error model; small validation overhead. + +### D7 — Treat CSI as a temporal delta, not absolute truth + +CSI is noisy and environment-specific. **rvCSI frames CSI as a temporal delta stream against learned baselines**, not as exact vision. +*Consequences:* honest product claims; good fit for presence/motion/drift/anomaly; identity and exact pose excluded from core claims. + +### D8 — RuVector is RF memory + +CSI becomes far more valuable stored as temporal embeddings and room signatures. **rvCSI integrates with RuVector** for vector storage, similarity search, drift detection, and sensor-graph relationships. +*Consequences:* rvCSI joins the broader ruvnet cognitive stack; RF field history becomes queryable; requires embedding design and retention policy. + +### D9 — Design for replayability + +Signal algorithms need repeatable benchmarks and debugging. **rvCSI supports deterministic replay** of captured sessions (timestamps, ordering, validation decisions, event output, calibration version, runtime config all preserved). +*Consequences:* easier testing; better audit trail; enables benchmark datasets. + +### D10 — Separate detection from decision + +rvCSI detects RF events; agents/applications decide what to do. **rvCSI emits events with confidence and evidence and performs no high-consequence actions by default.** +*Consequences:* cleaner safety model; clean integration with Cognitum proof-gated execution; applications implement policy. + +### D11 — Local-first operation + +RF sensing is privacy-sensitive and often valuable offline. **rvCSI runs locally by default and requires no cloud service**; remote observability is opt-in. +*Consequences:* better privacy posture; usable in industrial/care/sovereign deployments; remote observability must be explicitly enabled. + +### D12 — MCP tools are read-first, write-gated + +Agents should observe RF state safely; device mutation and calibration change system behavior. **MCP tools default to read actions**; capture start/stop, calibration, and export are gated. +*Consequences:* safer agent integration; lower accidental device disruption; more explicit operational control. + +### D13 — Quality scoring is mandatory + +CSI quality varies widely by chip, antenna, environment, channel, and interference. **Every frame, window, and event carries quality or confidence scoring.** +*Consequences:* downstream systems can suppress weak evidence; easier debugging; requires calibration and thresholds. Where a detector compares against a learned baseline (e.g. baseline-drift / anomaly), thresholds are expressed **relative to the baseline's magnitude**, not as absolute amplitude units, so a single tuning is valid across sources whose raw CSI scales differ by orders of magnitude (raw `int8` ESP32 vs. `int16`-scaled Nexmon vs. baseline-subtracted streams). + +### D14 — Versioned calibration profiles + +Room baselines change over time. **Calibration profiles are versioned**, and event outputs reference the calibration version used. +*Consequences:* more auditable detection; replay can reproduce prior outputs; slight storage overhead. + +### D15 — Hardware adapters are plugins + +Device support will evolve and vary by platform. **Source adapters are plugins behind a common Rust trait** (`CsiSource`). +*Consequences:* easier support for Nexmon/ESP32/Intel/Atheros/SDR/future sources; cleaner testability; adapter certification becomes important. + +--- + +## 3.

Consequences + +**Positive** + +- CSI becomes reusable infrastructure: npm-installable, reproducible, typed, safe-parsed, embeddable, WebSocket-streamable, WASM-portable, MCP-exposed, agent-integrable. +- One application codebase works across Nexmon, ESP32, Intel, and Atheros sources. +- Bad packets cannot crash the daemon; unattended operation becomes realistic. +- RuView/RuVector/Cognitum/agents gain a validated live source of RF observations. +- Honest product framing ("structural sensing") avoids over-claiming. + +**Negative / costs** + +- Larger build surface: Rust core + napi-rs native module + C shims + TypeScript packages + prebuild pipeline. +- Adapter certification and a supported-hardware matrix become ongoing maintenance. +- Embedding design, calibration thresholds, and retention policy are non-trivial open questions (tracked in the PRD). +- Risk of duplicating `wifi-densepose-signal` / `wifi-densepose-ruvector`; mitigated by wrapping, not re-implementing. + +**Risks** + +- Nexmon coupling: some device support remains dependent on upstream firmware/driver projects. +- CSI quality variance: weak-signal environments may yield low-confidence events; mitigated by mandatory quality scoring (D13) and versioned calibration (D14). + +--- + +## 5. Alternatives considered + +| Alternative | Why not | +|-------------|---------| +| Pure-Python runtime (extend the v1 stack) | Fragile under malformed packets; GC pauses break the < 50 ms latency target; poor unattended stability. | +| Pure-Rust including firmware (replace Nexmon) | Enormous scope; vendor-specific; would block v0 indefinitely. D2 keeps C at the boundary instead. | +| Per-source SDKs (no normalized schema) | Pushes device specifics into application code; defeats the "same app code across adapters" success criterion. | +| WASM-only core | No raw socket / serial / monitor-mode access for live capture; fine for offline parsing (a later target) but not v0 live capture. | +| Cloud-first ingestion | Violates the privacy posture and the local-first requirement; unacceptable for care/industrial/sovereign deployments. | + +--- + +## 6.

The baseline-drift detector measures drift **relative to the running baseline's RMS magnitude** (a fraction, not absolute amplitude units), so the same thresholds work for raw `int8` ESP32 CSI, `int16`-scaled Nexmon CSI, and baseline-subtracted streams alike — see ADR-095 D13. | +| `rvcsi-adapter-file` | no (`forbid`) | `rvcsi-core` | The `.rvcsi` capture format (JSONL: a header line + one `CsiFrame` per line), `FileRecorder`, and `FileReplayAdapter` (a `CsiSource`) — deterministic replay (D9). | +| `rvcsi-adapter-nexmon` | **yes** (FFI only) | `rvcsi-core` + the C shim | The **napi-c** seam: `native/rvcsi_nexmon_shim.{c,h}` compiled via `build.rs`+`cc`, a documented `ffi` module wrapping it, a pure-Rust libpcap reader (`pcap.rs`), the Nexmon-chip / Raspberry-Pi-model registry (`chips.rs` — `NexmonChip`, `RaspberryPiModel` incl. **Pi 5**, profile builders), and two `CsiSource`s — `NexmonAdapter` (rvCSI-record buffers) and `NexmonPcapAdapter` (real nexmon_csi UDP payloads inside a `.pcap`, with chip auto-detection). | +| `rvcsi-ruvector` | no (`forbid`) | `rvcsi-core` | The RuVector RF-memory bridge: deterministic `window_embedding`/`event_embedding`, `cosine_similarity`, the `RfMemoryStore` trait, and `InMemoryRfMemory` + `JsonlRfMemory` (a standin until the production RuVector binding lands). | +| `rvcsi-runtime` | no (`forbid`) | core, dsp, events, adapter-file, adapter-nexmon, ruvector | The composition layer (no FFI): `CaptureRuntime` (a `CsiSource` + `validate_frame` + `SignalPipeline` + `EventPipeline`) plus one-shot helpers (`summarize_capture`, `decode_nexmon_records`, `decode_nexmon_pcap`, `summarize_nexmon_pcap`, `events_from_capture`, `export_capture_to_rf_memory`).

Higher layers wire `SignalPipeline::process_frame` → `WindowBuffer::push` when they want cleaned frames. + +The MCP tool server (`rvcsi-mcp`) and the long-running daemon (`rvcsi-daemon`) — and live radio capture — are *not* in this ADR's scope; they sit on top of `rvcsi-runtime` / the crates above and are tracked as follow-ups. The `@ruv/rvcsi` npm package ships alongside `rvcsi-node`. + +### 2.2 The napi-c shim — record formats and contract + +`native/rvcsi_nexmon_shim.{c,h}` is the only C in the runtime. It handles **two byte formats** (ABI `1.1`): + +**(1) The "rvCSI Nexmon record"** — a compact, self-describing record (`'RVNX'` magic, version, flags, RSSI/noise, channel, bandwidth, timestamp, then interleaved `int16` I/Q in Q8.8 fixed point; total `24 + 4*N`). Used by the `rvcsi capture`/`record` recorder, the file replay path, and tests. Functions: `rvcsi_nx_record_len`, `rvcsi_nx_parse_record`, `rvcsi_nx_write_record`. + +**(2) The *real* nexmon_csi UDP payload** — what the patched Broadcom firmware actually sends to the host (port 5500 by default): the 18-byte header `magic=0x1111 (2) · rssi int8 (1) · fctl (1) · src_mac (6) · seq_cnt (2) · core/stream (2) · chanspec (2) · chip_ver (2)`, followed by `nsub` complex CSI samples. The shim implements the **modern int16 I/Q export** (`nsub` pairs of little-endian `int16` `(real, imag)`, raw counts — what CSIKit / `csireader.py` read for the BCM43455c0 / 4358 / 4366c0); `nsub` is derived from the payload length, `(len − 18) / 4`. Functions: `rvcsi_nx_csi_udp_header` (just the 18-byte header), `rvcsi_nx_csi_udp_decode` (header + CSI body, `csi_format` selector), `rvcsi_nx_csi_udp_write` (synthesize a payload — tests/examples), and `rvcsi_nx_decode_chanspec` (decode a Broadcom d11ac chanspec word → `channel` = `chanspec & 0xff`, bandwidth from bits `[13:11]` cross-checked against the FFT size, band from bits `[15:14]` cross-checked against the channel number). The legacy nexmon *packed-float* export used by some 4339/4358 firmwares is a documented follow-up (it sits behind the same `csi_format` selector). + +The `timestamp_ns` of a frame from format (2) comes from the **pcap packet timestamp**, not the wire (nexmon_csi doesn't carry one). The pcap file itself is parsed in **pure Rust** (`rvcsi-adapter-nexmon::pcap` — classic libpcap, all four byte-order/timestamp-resolution magics, Ethernet / raw-IPv4 / Linux-SLL link types; pcapng is a follow-up): peeling the Ethernet/IPv4/UDP headers down to the payload is not a vendor-fragility concern, so it doesn't belong in C. + +Contract (both formats): + +- **Allocation-free, global-free.** Every read is bounds-checked against the caller-supplied length; nothing can scribble outside caller buffers; no `malloc`, no statics. +- **Structured errors, never panics.** Functions return one of a small set of `RvcsiNxError` codes (`TOO_SHORT`, `BAD_MAGIC`, `BAD_VERSION`, `CAPACITY`, `TRUNCATED`, `ZERO_SUBCARRIERS`, `TOO_MANY_SUBCARRIERS`, `NULL_ARG`, `BAD_NEXMON_MAGIC`, `BAD_CSI_LEN`, `UNKNOWN_FORMAT`); `rvcsi_nx_strerror` maps each to a static string. +- **ABI versioned.** `rvcsi_nx_abi_version()` returns `major << 16 | minor` (`0x0001_0001`); the Rust side `debug_assert`s the major matches the header it was compiled against. The minor was bumped from `1.0` → `1.1` when the format-(2) entry points landed (additive — format (1) is unchanged). +- The Rust `ffi` module wraps these in safe functions (`record_len`, `decode_record`, `encode_record`, `decode_chanspec`, `parse_nexmon_udp_header`, `decode_nexmon_udp`, `encode_nexmon_udp`, `shim_abi_version`); every `unsafe` block is limited to the FFI call (and reading back C-initialised structs) and carries a `// SAFETY:` comment, per the project rule. + +**Chip registry (`rvcsi-adapter-nexmon::chips`).** nexmon_csi runs on a handful of patched Broadcom/Cypress chips; `NexmonChip` names them, `RaspberryPiModel` maps Pi boards to their chip, and `nexmon_adapter_profile` / `raspberry_pi_profile` build the [`AdapterProfile`] (supported channels / bandwidths / expected subcarrier counts — 20→64, 40→128, 80→256, 160→512) `validate_frame` bounds CSI frames against. The **Raspberry Pi 5** carries the same **CYW43455 / BCM43455c0** 802.11ac wireless as the Pi 3B+ / Pi 4 / Pi 400 (20/40/80 MHz, 2.4 + 5 GHz) — the chip with the most mature nexmon_csi support — so `RaspberryPiModel::Pi5 → NexmonChip::Bcm43455c0`; the Pi Zero 2 W is `Bcm43436b0` (2.4 GHz, ≤40 MHz). `NexmonPcapAdapter` **auto-detects** the chip from each packet's `chip_ver` word (`0x4345` → `Bcm43455c0`, etc.) and uses the matching profile; `.with_chip(...)` / `.with_pi_model(...)` override it. `NexmonChip::from_chip_ver` and the `chip_ver` field are best-effort/preserved respectively — the c0/b0 revision suffix isn't carried by that word, and the int16-vs-packed-float export distinction is handled by the `csi_format` selector, not by chip-ver parsing. + +A real deployment captures with `tcpdump -i wlan0 dst port 5500 -w csi.pcap` on the Pi and feeds the `.pcap` to `NexmonPcapAdapter::open` (or `rvcsi record --source nexmon-pcap --in csi.pcap --out cap.rvcsi --chip pi5`, then the rest of the toolchain works on the `.rvcsi`; `rvcsi inspect-nexmon` reports the resolved chip, `rvcsi nexmon-chips` lists the matrix). Production *live* capture (binding the UDP socket, monitor mode, firmware patch hooks) is a later increment that reuses the same shim parse path — the shim's job is the *parse*, not the *socket*. + +### 2.3 The napi-rs surface — what crosses the seam + +`rvcsi-node` is a `["cdylib", "rlib"]` crate (cdylib = the `.node` addon; rlib so `cargo test --workspace` can link and test the Rust side without Node). Rules: + +- **Only normalized/validated data crosses.** The boundary types are JS-friendly mirrors of `CsiFrame`/`CsiWindow`/`CsiEvent`/`AdapterProfile`/`SourceHealth`, or plain JSON strings — never raw pointers, never `Pending` frames. A frame is run through `rvcsi_core::validate_frame` before it is handed to JS. +- **Errors map to JS exceptions** via napi-rs's `Result` integration; `RvcsiError`'s `Display` is the message. +- **The build emits link args + `binding.js`/`binding.d.ts`** via `napi_build::setup()` in `build.rs`; the `@ruv/rvcsi` npm package's hand-written `index.js`/`index.d.ts` wrap that loader and `JSON.parse` the addon's returns into plain `CsiFrame`/`CsiWindow`/`CsiEvent`/`SourceHealth`/`CaptureSummary`/`NexmonPcapSummary`/`DecodedChanspec` objects. +- The free functions exposed are: `rvcsiVersion`, `nexmonShimAbiVersion` (the linked shim's ABI), `nexmonDecodeRecords`, `nexmonDecodePcap`, `inspectNexmonPcap`, `decodeChanspec`, `inspectCaptureFile`, `eventsFromCaptureFile`, `exportCaptureToRfMemory`; plus the `RvcsiRuntime` streaming class (`openCaptureFile` / `openNexmonFile` / `openNexmonPcap` factories + `nextFrameJson` / `nextCleanFrameJson` / `drainEventsJson` / `healthJson`). + +### 2.4 Build & test invariants + +- `cargo build --workspace` and `cargo test --workspace --no-default-features` (the repo's pre-merge gate) must stay green; the new crates add tests and don't regress the existing 1,031+. +- `rvcsi-node` stays a workspace *member* (not `exclude`d like `wifi-densepose-wasm-edge`): on Linux/macOS a napi cdylib links fine with Node symbols left undefined (resolved at addon-load time), so `cargo build`/`cargo test` work without a Node toolchain. Only `napi build` (npm packaging) needs Node. +- No new heavy dependencies in the rvCSI crates: `serde`, `serde_json`, `thiserror`, `cc` (build only), `napi`/`napi-derive`/`napi-build`, `clap` (CLI only), `tempfile` (dev only). DSP math is hand-rolled — no `ndarray`/`rustfft`. + +--- + +## 3. Consequences + +**Positive** + +- The two FFI seams are small, audited, and independently testable: the C shim round-trips through Rust tests; the napi surface tests run under `cargo test` without Node. +- `unsafe` is confined to one crate (`rvcsi-adapter-nexmon`) and within it to one module (`ffi`), every block documented. +- Each leaf crate (`rvcsi-dsp`, `rvcsi-events`, `rvcsi-adapter-file`, `rvcsi-ruvector`) depends only on `rvcsi-core`, so they can evolve (and be reviewed, and be swarm-implemented) independently. +- The `.rvcsi` JSONL capture format and the `JsonlRfMemory` standin make the whole pipeline runnable and testable end-to-end before any hardware or the real RuVector binding exists. + +**Negative / costs** + +- A `cc`-built C library means a C toolchain is required to build `rvcsi-adapter-nexmon` (already true for many workspace crates via transitive `cc` deps; acceptable). +- The "rvCSI Nexmon record" is a *normalized* format, not byte-identical to any upstream nexmon_csi build — a thin demux/transcode step is needed when wiring real Nexmon output. This is intentional (we control the contract the shim parses) and documented. +- JSONL captures are larger than a packed binary format; fine for v0 (and the PRD already standardizes on JSON/WebSocket on the wire), revisit if capture size becomes a problem. +- `rvcsi-node` as a workspace member adds the `napi` dependency tree to `cargo build --workspace`; mitigated by it being a small, well-maintained crate. + +**Risks** + +- napi-rs major-version churn could change the macro/`build.rs` surface; pinned to `napi = "2.16"` in workspace deps, bumped deliberately. +- If a future platform can't link a napi cdylib under plain `cargo build`, `rvcsi-node` moves to the workspace `exclude` list (like `wifi-densepose-wasm-edge`) with a separate build command — same pattern, already established. + +--- + +## 4. Alternatives considered + +| Alternative | Why not | +|-------------|---------| +| One mega-crate `rvcsi` instead of eight | Couples DSP/events/adapters/FFI; can't review or implement them independently; bloats compile units for downstream users who only want `rvcsi-core`. | +| `bindgen` for the C shim | Pulls in `libclang`; the shim's C API is six functions — hand-written `extern "C"` decls are clearer and dependency-free. | +| Binary `.rvcsi` capture format (bincode/custom) | Smaller, but not human-inspectable; JSONL is debuggable, append-friendly, and matches the PRD's on-the-wire JSON. Revisit if size matters. | +| Expose raw `CsiFrame` pointers / typed arrays across napi for zero-copy | Violates ADR-095 D6 (validate-before-FFI) and the "no raw pointers to TS" safety NFR; the per-frame copy cost is negligible at the target rates. | +| `wasm-bindgen` instead of napi-rs for the JS surface | WASM can't do live capture (no raw sockets/serial); great for offline parsing (a later target) but not the primary Node runtime. | +| `rvcsi-events` depending on `rvcsi-dsp` for window stats | Adds a coordination point for two leaf crates; the stats are a few lines — keep the leaves independent and let higher layers compose them. | + +--- + +## 5.

The crate topology — `rvcsi-core` (kernel) → `rvcsi-dsp` / `rvcsi-events` / `rvcsi-adapter-{file,nexmon}` / `rvcsi-ruvector` (leaves) → `rvcsi-runtime` (composition) → `rvcsi-node` (napi-rs) + `rvcsi-cli` — is fixed by ADR-096. + +**Today, RuView vendors rvCSI but does not consume it.** No Cargo `Cargo.toml` in `v2/crates/*` depends on any `rvcsi-*` crate; no Rust source `use rvcsi_…`; no `@ruv/rvcsi` import in `ui/`, `dashboard/`, or anywhere else.

Those modules go beyond rvCSI's scope (cross-viewpoint fusion, AETHER re-ID, RF tomography, longitudinal biomechanics, adversarial detection) and *stay* in RuView — they consume rvCSI's normalized `CsiFrame` rather than reimplementing the parsing/validation/DSP plumbing below them. +- Not a forced migration of every consumer simultaneously.

Decision + +**Adopt rvCSI as the primary CSI ingestion / validation / DSP / event-extraction runtime for RuView, consumed via the published crates.** The decisions below are the architectural contract for that adoption. + +### D1 — Depend on the published `rvcsi-*` crates, not the submodule path + +Each consuming RuView crate adds `rvcsi-runtime = "0.3"` (or whichever rvCSI crate(s) it needs) to its `Cargo.toml`. Cargo resolves these from crates.io. `vendor/rvcsi` remains a **pinned source-of-truth for local dev / patches / offline builds**, not the build path. +*Consequences:* normal `cargo build` works without `git submodule update --init`; version pinning is explicit in `Cargo.toml`; coordinated upgrades are a single SemVer bump per crate; the submodule pin can lag and that's fine. + +### D2 — `wifi-densepose-sensing-server` is the pilot consumer + +The sensing-server (Axum REST + WebSocket) is the smallest, best-bounded touchpoint: its UDP CSI receiver and `latest`/`vital-signs`/`edge-vitals` endpoints map cleanly onto `rvcsi-runtime::CaptureRuntime` + the `rvcsi_events` pipeline. The pilot replaces only the **ingestion / validation / DSP / event** path; the existing handlers, the WebSocket fan-out, the RVF model loader, the adaptive classifier and the vital-sign extractor stay. +*Consequences:* one PR-sized adoption to learn from before touching the heavier crates; integration tests in `wifi-densepose-sensing-server` exercise the rvCSI surface against synthetic + real ESP32 captures (the `scripts/esp32_jsonl_to_rvcsi.py` bridge in the standalone repo is the de-facto fixture path). + +### D3 — `wifi-densepose-signal` is *layered on top of* rvCSI, not replaced + +The RuvSense modules (`multistatic`, `phase_align`, `tomography`, `pose_tracker`, `field_model`, `longitudinal`, `intention`, `cross_room`, `gesture`, `adversarial`, `coherence_gate`) go strictly beyond `rvcsi-dsp` and stay in RuView. They consume `rvcsi_core::CsiFrame` / `CsiWindow` instead of the current `wifi_densepose_core::CsiFrame`-like types. +The genuinely-overlapping primitives in `wifi-densepose-signal` (basic DSP — DC removal, phase unwrap, Hampel, smoothing, baseline subtraction, motion-energy / presence) are either replaced with `rvcsi-dsp::stages::*` calls or kept as thin shims that delegate. A single `From for rvcsi_core::CsiFrame` (and the reverse) lives in `wifi-densepose-signal` during the transition. +*Consequences:* the SOTA work stays in RuView (where it belongs); the parsing/validation/baseline plumbing centralizes in rvCSI; the public API of `wifi-densepose-signal` shifts gradually toward "modules built on top of `rvcsi-*`". + +### D4 — `wifi-densepose-hardware` stops carrying ESP32 wire-format parsing + +The ESP32 ADR-018 binary frame parsing (magic 0xC5110001, 20-byte header, int8 I/Q — see the `scripts/esp32_jsonl_to_rvcsi.py` bridge in the rvCSI repo) becomes part of a new `rvcsi-adapter-esp32` crate (ADR-095 §1.2 / D15 follow-up, owned in the rvCSI repo). `wifi-densepose-hardware` keeps the firmware/aggregator side (UDP listener, mesh, TDM, channel hopping, NVS provisioning) — i.e. the parts above the wire — and emits parsed `CsiFrame`s via the new adapter trait. +*Consequences:* the firmware-side and host-side concerns split cleanly; the parser lives once (in rvCSI) and is testable in isolation; the wire format is documented once. + +### D5 — Embeddings & RF memory: the two `ruvector` paths stay separate (for now) + +`wifi-densepose-ruvector` (ADR-016) is the **training** pipeline integration — feeding RuvSense outputs into RuVector for cross-viewpoint fusion, AETHER contrastive embeddings, domain generalization (MERIDIAN). `rvcsi-ruvector` is the **runtime RF-memory** bridge — deterministic per-window/per-event embeddings + `RfMemoryStore`. They serve different jobs; both stay. A follow-up ADR can unify them once `rvcsi-ruvector`'s production backend (currently the `JsonlRfMemory` standin) lands the real RuVector binding. +*Consequences:* no churn in the training pipeline today; the runtime memory and the training-time fusion remain distinct contexts in the DDD sense. + +### D6 — Schema: `rvcsi_core::CsiFrame` becomes the boundary type at the runtime edge + +At the *runtime* edge (sensing-server, future daemon, any new adapter), `rvcsi_core::CsiFrame` is the validated normalized object. RuView's internal types (`wifi_densepose_core::CsiFrame` and friends) continue to exist for training and SOTA pipelines, but a single explicit conversion happens at the boundary and is the only allowed translation point. +*Consequences:* one validation gate at one edge; downstream code stops re-deriving amplitude/phase / re-checking finiteness; the `validate_frame` quality scoring is the only source of truth for "is this frame usable". + +### D7 — Versioning: track rvCSI via SemVer-compatible ranges + pin the submodule + +`Cargo.toml` deps use `rvcsi-runtime = "0.3"` etc. (`^0.3`, so 0.3.x picks up automatically). The `vendor/rvcsi` submodule pin is **bumped per RuView release** to whatever rvCSI commit RuView was tested against — providing reproducible offline builds and a source-level reference, even though the actual build resolves from crates.io. +*Consequences:* RuView keeps moving; rvCSI patch releases roll in automatically; minor-version bumps require a deliberate `^0.3` → `^0.4` change (and a re-test of the consumers); the submodule pin advances with each release tag so it never silently drifts. + +### D8 — Replace `vendor/rvcsi` with crates.io once D1–D7 are merged + +If, after the pilot, every consumer depends on crates.io (no consumer touches `vendor/rvcsi/crates/*`), `vendor/rvcsi` is *redundant*.

Consequences + +**Positive** + +- Single normalized schema (`CsiFrame` / `CsiWindow` / `CsiEvent`) across RuView's runtime surface — fewer bespoke types, less duplication. +- Bad packets quarantined at one place (rvCSI's `validate_frame`), not at every consumer. +- New CSI sources (Intel `iwlwifi`, Atheros, SDR) plug in once at the rvCSI layer, work for every RuView consumer immediately. +- rvCSI's structured `RvcsiError` + the C shim's panic-free contract replace ad-hoc parser error handling in RuView's hardware-side code. +- The sensing-server inherits the FFI-boundary hardening from rvCSI (e.g. the NaN-safe `napi-c` encode fix in `rvcsi-adapter-nexmon 0.3.1` flows in automatically). + +**Negative / costs** + +- Two repos to keep in lockstep during the adoption (`ruvnet/RuView` + `ruvnet/rvcsi`). Mitigated by SemVer + the per-release submodule bump. +- Per-frame conversion at the boundary in P1/P2 (one `From for wifi_densepose_core::CsiFrame`-style hop). Cost is a single `Vec` clone of the I/Q + amplitude/phase arrays per frame; at the project's target rates this is well under the 50 ms latency budget. +- The training pipeline (`wifi-densepose-ruvector`) and the runtime RF memory (`rvcsi-ruvector`) coexist until D5's follow-up. +- The Nexmon ESP32 adapter (D4 / P3) is real work in the rvCSI repo before P3 can land. + +**Risks** + +- API drift between `wifi_densepose_core::CsiFrame` and `rvcsi_core::CsiFrame` if both keep evolving; mitigated by D6 (one explicit conversion point, every other consumer reads only `rvcsi_core::CsiFrame`). +- crates.io as a hard dependency — if crates.io is unreachable in an air-gapped build, `vendor/rvcsi` + `[patch.crates-io]` is the documented escape hatch. + +--- + +## 5. Alternatives considered + +| Alternative | Why not | +|---|---| +| Keep both in parallel indefinitely | Two diverging implementations of the same concepts → twice the bug-fix surface, twice the docs, twice the tests; defeats the reason rvCSI was extracted in the first place. | +| Big-bang adoption — replace `wifi-densepose-signal` end-to-end in one PR | Too much surface to land safely; the SOTA modules go *beyond* rvCSI's scope and don't lift cleanly. D3's "layered on top" preserves what matters. | +| Consume `vendor/rvcsi/crates/*` via path deps instead of crates.io | Couples RuView to the submodule's HEAD; loses the SemVer ratchet; makes `cargo build` fail when the submodule isn't initialized. D1 (published crates) is the standard pattern. | +| Move RuView itself into `ruvnet/rvcsi` (monorepo) | Defeats the reason rvCSI was extracted — rvCSI is a runtime usable beyond RuView (other agents, other apps, the standalone CLI + npm SDK). The repo split is intentional. | +| Stay on `wifi-densepose-signal` and treat rvCSI as a sibling library only | Means RuView reimplements every adapter, every validation rule, every event detector forever. D2's pilot validates whether the seams are right before committing to D3. | + +--- + +## 6. Open questions + +- **Per-subcarrier calibration baseline.** rvCSI's `events` pipeline benefits from a learned baseline (`SignalPipeline::baseline_amplitude`) — RuView's existing per-node calibration logic (in `wifi-densepose-sensing-server`'s field-model endpoints) should feed that baseline in. The plumbing is straightforward; documenting the format is a P1 sub-task. +- **Single-frame schema overhead.** `rvcsi_core::CsiFrame` carries `i_values + q_values + amplitude + phase + quality_reasons` (four `Vec` plus a `Vec`).

The user-facing prompt enumerated four candidate seams to evaluate: + +1. Streaming / pub-sub for the WebSocket fan-out (today: `tokio::sync::broadcast::channel::(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`). +2.

Multi-source merging / TDM coordination for the ESP32 mesh (ADR-029, ADR-073). +4. Backpressure / flow control between the UDP receiver and downstream consumers (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638` `udp_receiver_task`; firmware-side `stream_sender` ENOMEM backoff at `firmware/esp32-csi-node/main/csi_collector.c:223-228`). + +To evaluate each, we read midstream's workspace `Cargo.toml` (`vendor/midstream/Cargo.toml:1-99`), the `README.md` and `BENCHMARKS_SUMMARY.md`, and every crate's `lib.rs`: + +| Crate | File | LOC | Purpose (from header doc) | +|---|---|---:|---| +| `midstreamer-temporal-compare` | `vendor/midstream/crates/temporal-compare/src/lib.rs:1-697` | 697 | DTW, LCS, Levenshtein, generic pattern matching on `Sequence` of `TemporalElement` | +| `midstreamer-scheduler` | `vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:1-406` | 406 | Priority + deadline-aware task scheduler (RM, EDF, LLF) for low-latency real-time tasks | +| `midstreamer-attractor` | `vendor/midstream/crates/temporal-attractor-studio/src/lib.rs:1-482` | 482 | Phase-space reconstruction, Lyapunov exponents, attractor classification | +| `midstreamer-neural-solver` | `vendor/midstream/crates/temporal-neural-solver/src/lib.rs:1-509` | 509 | LTL / CTL / MTL temporal-logic verification with neural reasoning | +| `midstreamer-strange-loop` | `vendor/midstream/crates/strange-loop/src/lib.rs:1-496` | 496 | Multi-level meta-learning, self-referential systems | +| `midstreamer-quic` | `vendor/midstream/crates/quic-multistream/src/lib.rs:1-255`, `native.rs:1-303`, `wasm.rs:1-307` | 865 | Thin wrapper over `quinn` (native) and `WebTransport` (WASM); generic QUIC streams | + +Plus a TypeScript layer (`vendor/midstream/npm/`, `vendor/midstream/npm-wasm/`) whose product is "real-time LLM streaming" — OpenAI Realtime API client, RTMP / WebRTC / HLS for video, an in-console dashboard, a Whisper transcription scaffold, an MCP server for LLM agents. + +The top-level identity is unambiguous: `Cargo.toml:16` describes the package as **`"Real-time LLM streaming with inflight analysis"`**, and the README (`vendor/midstream/README.md:45-80`) frames midstream as a platform that "analyzes [LLM] responses **as they stream in real-time** — enabling instant insights, pattern detection, and intelligent decision-making" — i.e. the streaming domain is **LLM tokens and dashboard telemetry**, not RF signals. A search for any of `csi`, `wifi`, `sensing`, or `sensor` across `vendor/midstream/crates/*/src/*.rs` returns zero hits. + +This shapes the conclusion: midstream's *abstractions* (DTW pattern matching, attractor analysis, LTL verification, meta-learning) were chosen for a fundamentally different problem domain than CSI, and its *transport* (QUIC) is a thin `quinn` wrapper rather than a sensing-aware backplane. The candidate seams enumerated above are either already filled by simpler primitives in RuView, or filled better by rvCSI under ADR-097. + +### 1.1 What this ADR is *not* + +- Not a judgment on midstream's quality. It has 139 passing tests and clean Rust; it is well-engineered for its target domain. +- Not a decision to drop `vendor/midstream`. The submodule pin is cheap to keep, and the carve-outs in §3 may justify revisiting it. +- Not a position on the *standalone* midstream product (LLM streaming, OpenAI Realtime, dashboards). That product is unaffected by this ADR. + +--- + +## 2. Decision + +**Reject midstream as a system component of RuView.** The four candidate seams are either filled (well) by existing RuView primitives, or are filled by rvCSI's freshly-adopted `EventPipeline` and `RfMemoryStore`. The eight decisions below are the architectural contract. + +### D1 — Streaming / pub-sub for the WebSocket fan-out: no change + +RuView's sensing-server currently fans out updates to WebSocket clients via `tokio::sync::broadcast::channel::(256)` (`v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`). midstream offers no equivalent in-process broadcast primitive — its TypeScript dashboard fan-out is HTTP-server based (`vendor/midstream/npm/src/dashboard.ts`), and its Rust `midstreamer-quic` crate is a generic point-to-point QUIC wrapper (`vendor/midstream/crates/quic-multistream/src/native.rs:31-69`), not a pub-sub bus. + +Tokio's `broadcast` channel is the standard Rust idiom for this pattern, costs effectively nothing per subscriber, integrates with the rest of the Axum + Tokio stack already in use (`v2/crates/wifi-densepose-sensing-server/src/main.rs:36,47`), and is what `rvcsi-runtime` itself uses for event distribution (`vendor/rvcsi/crates/rvcsi-runtime/src/lib.rs`). **Keep `tokio::sync::broadcast`.** +*Consequences:* zero migration; zero new dependency surface; the WebSocket handlers at `main.rs:1989,2030` continue to work unchanged. + +### D2 — CSI → DSP → event pipeline: stay on rvCSI's `EventPipeline` + +ADR-097 D2 just adopted `rvcsi-runtime::CaptureRuntime` + `rvcsi_events::EventPipeline` as the CSI ingestion / DSP / event-extraction path. `EventPipeline` is **deterministic, synchronous, single-frame-at-a-time** (`vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs:1-5`: *"Feed it frames with `EventPipeline::process_frame` and drain the tail with `EventPipeline::flush`"*) — and that determinism is load-bearing for ADR-095 D9 (replayability) and ADR-095 D13 (quality scoring against learned baselines). + +midstream's stream-processing primitives are designed for the opposite shape: `temporal-attractor-studio` (phase-space reconstruction, Lyapunov exponents) and `temporal-neural-solver` (LTL formula verification) operate on **trajectories** of multi-dimensional states over hundreds-to-thousands of samples (`vendor/midstream/README.md:528-531`: *"Attractor detection: <5ms for 1000-point series"*) — that is closer to RuView's existing RuvSense modules (`v2/crates/wifi-densepose-signal/src/ruvsense/longitudinal.rs`, `intention.rs`) than to anything the runtime DSP layer needs. + +Replacing rvCSI's event detectors with midstream constructs would (a) break determinism, (b) re-introduce a parallel CSI-processing implementation — exactly the duplication ADR-097 was opened to remove — and (c) force RuView to invent a `Sequence` shim around `CsiFrame` for marginal benefit. **Stay on `rvcsi-events::EventPipeline`.** +*Consequences:* the determinism / replay guarantees of ADR-095 D9 and ADR-097 D6 remain intact; the work to land `rvcsi-adapter-esp32` (ADR-097 D4, P3) is not duplicated. + +### D3 — TDM / multi-source merging: stay on the existing aggregator + +The ESP32 mesh's multi-source merging is in `v2/crates/wifi-densepose-hardware/src/aggregator/mod.rs:74-220` — a `UdpSocket`-backed aggregator (`mod.rs:74,85`) that receives parsed `CsiFrame`s from N nodes and forwards them on a `SyncSender` to the consumer. The TDM coordination (slot assignment, channel hopping, dwell time) lives in firmware (`firmware/esp32-csi-node/main/`) and is governed by ADR-029 and ADR-073. midstream offers nothing for either side: it has no UDP merger, no slot scheduler, and no firmware-side primitives. + +`midstreamer-scheduler` is conceptually adjacent — it does priority + deadline-aware scheduling (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`: `RateMonotonic`, `EarliestDeadlineFirst`, `LeastLaxityFirst`, `FixedPriority`) — but its target is **in-process tokio tasks on a 4-thread executor** (`vendor/midstream/README.md:466-477`: *"4 worker threads"*, *"<50 ns scheduling latency"*), not the cross-device, wall-clock-anchored TDM that RuvSense needs. **Keep the existing `wifi-densepose-hardware` aggregator and firmware-side TDM.** +*Consequences:* ADR-029 stays as-is; the work to migrate the parser to `rvcsi-adapter-esp32` (ADR-097 D4) is unaffected. + +### D4 — UDP receiver backpressure / flow control: existing solutions are correct at each end + +There are two distinct backpressure problems in RuView, and neither benefits from midstream: + +- **Firmware side (`firmware/esp32-csi-node/main/csi_collector.c:64,223-228`):** lwIP pbuf exhaustion produces `ENOMEM` when the ESP32 tries to UDP-send faster than the network drains. The fix in code is a rate-limit on `stream_sender_send` *inside the CSI callback*. This is a C-level firmware concern with no Rust analogue — midstream cannot run on the ESP32. +- **Host side (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638-3640`, `4769`):** `udp_receiver_task` reads from `UdpSocket` and pushes onto `broadcast::channel::(256)`. The bounded channel is itself the backpressure mechanism: lagged subscribers see `RecvError::Lagged`, the buffer wraps, no producer ever blocks. The 256-slot capacity is sized to one second of frame envelopes at the target rate; the per-second packet-yield collapse symptom (`adaptive_controller_decide.c:26-28`) is detected and surfaced by ADR-039 / ADR-081's `pkt_yield_per_sec` accessor, not by transport-layer flow control. + +midstream's `quic-multistream` provides per-stream prioritization (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`), which is a useful flow-control primitive *for QUIC* but not for the UDP-CSI / WS-fan-out topology RuView actually uses. Adopting QUIC end-to-end would mean (a) replacing the ESP32's UDP sender — which would need a QUIC stack on a memory-constrained Xtensa MCU and is out of scope for this project — or (b) terminating QUIC at the aggregator only, which provides no benefit the current bounded `broadcast` channel doesn't. **Keep the existing two-tier backpressure.** +*Consequences:* the ENOMEM rate-limit at `csi_collector.c:223-228` and the bounded `broadcast::channel::(256)` at `main.rs:4769` continue to be the load-bearing primitives. + +### D5 — Carve-out: `temporal-compare` as a future RuvSense-side building block + +`midstreamer-temporal-compare` (`vendor/midstream/crates/temporal-compare/src/lib.rs:1-697`) is a clean DTW / LCS / Levenshtein implementation with an LRU cache. RuView's gesture detector at `v2/crates/wifi-densepose-signal/src/ruvsense/gesture.rs` already does DTW template matching, and the longitudinal analysis at `ruvsense/longitudinal.rs` could plausibly benefit from cached pattern matching. If we ever need a *separate* DTW implementation that is decoupled from RuvSense's internal types, `temporal-compare` is a reasonable starting point — but only if and when that need arises. + +We **do not adopt it today** because RuvSense's gesture matcher already exists, works, and uses RuView-native types, and pulling in `dashmap`, `lru`, and a generic `TemporalElement` abstraction would be net-negative right now. **Tracked as a future evaluation, not a decision.** +*Consequences:* zero today; one named option for a future ADR if a "second" DTW pattern appears. + +### D6 — Carve-out: `nanosecond-scheduler` for *host-side* edge tier scheduling (future) + +If ADR-039's edge-intelligence tier scheduling ever moves from the ESP32 onto a host-side coordinator (e.g. a Raspberry Pi running the cluster aggregator), `nanosecond-scheduler`'s deadline-aware policies (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`) could plausibly host that scheduler. Today the scheduling is firmware-side and the C-level RTOS handles it; there is nothing to schedule in Rust at the granularity midstream offers. + +Again: **not a current decision, just an option kept open.** +*Consequences:* zero today. + +### D7 — Submodule disposition: keep `vendor/midstream` + +`vendor/midstream` is one git submodule pin; the build does not depend on it; it does not slow down `cargo build --workspace`; and the carve-outs in D5/D6 leave the door open. Removing the submodule would also remove the reference material that justified the carve-outs. + +**Keep the submodule, no per-release pin advancement.** Unlike `vendor/rvcsi` (whose pin is bumped per RuView release under ADR-097 D7), `vendor/midstream` has no in-build consumer to validate against. If D5 or D6 ever activates, *that* ADR will start the per-release pin process. Until then the pin can drift freely. +*Consequences:* one line of `.gitmodules` (`.gitmodules:1-4`) stays; `git submodule update --init` remains a no-op for normal RuView development. + +### D8 — Documentation: cross-reference, don't import + +The ADR index (`docs/adr/README.md`) gets ADR-098 added under "Architecture and infrastructure". No other docs are updated. The README on the RuView side is untouched; midstream is not part of the RuView platform story. +*Consequences:* one row added to the ADR index; no churn elsewhere. + +--- + +## 3. Why not adopt (the rejection record) + +For institutional memory, the table below records what each midstream crate *would* solve and the alternative RuView already uses.

Consequences + +**Positive** + +- Zero net change to RuView's build, runtime, or surface area; ADR-097's phased rvCSI adoption proceeds unaffected. +- The decision space around midstream is now bounded and documented; future contributors and AI agents see "ADR-098 already evaluated this; here is why not" before re-opening the question. +- The two crate-level carve-outs (D5, D6) are explicit, so if the relevant seams appear later, the evaluation can pick up from this ADR rather than start over. +- `vendor/midstream` (the submodule) remains as reference material, but is correctly marked as not part of the build path. + +**Negative / costs** + +- One more vendored repo with no in-build consumer — a small but non-zero cognitive load (mitigated by D7's explicit "do not bump the pin"). +- If midstream's published crates evolve materially (e.g. a CSI-aware feature lands), the reasoning in §3 needs revisiting; this is the standard "rejected ADRs go stale" risk and applies to every Rejected ADR in the index. + +**Risks** + +- The most plausible failure mode of this ADR is *not* "we should have adopted midstream"; it is "we re-open the question in six months without re-reading this ADR." Mitigated by indexing ADR-098 in `docs/adr/README.md` and by the per-crate table in §3 being precise enough to short-circuit the next evaluator. + +--- + +## 5. Alternatives considered + +| Alternative | Why not | +|---|---| +| **Adopt midstream wholesale as RuView's streaming backbone** | Would force the CSI pipeline into the `Sequence` shape (`vendor/midstream/crates/temporal-compare/src/lib.rs:42-70`) and the `quic-multistream` transport (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`) — both are designed for LLM tokens / arbitrary streams, not validated RF frames with quality scoring. Conflicts directly with ADR-095 D5 (one `CsiFrame` schema), D6 (validate before crossing boundaries), and D9 (deterministic replay). | +| **Replace `tokio::sync::broadcast` with midstream's QUIC fan-out** | Solves no observed problem. `broadcast::channel::(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769` handles N WebSocket subscribers at zero per-subscriber cost; the lagged-subscriber semantics (`RecvError::Lagged`) are exactly what an event-feed wants. QUIC adds TLS + congestion control + per-stream priority — useful for *external* clients across a network, but the sensing-server's clients connect over WS on the same host or LAN. | +| **Replace `EventPipeline` with `temporal-attractor-studio` / `temporal-neural-solver`** | `EventPipeline` is deterministic by contract (`vendor/rvcsi/crates/rvcsi-events/src/lib.rs:20`) and ADR-097 just made it RuView's event source of truth. Attractor analysis and LTL verification operate on entirely different abstractions; using them as event detectors would re-invent rvCSI's pipeline in a less-determined way. | +| **Adopt `midstreamer-temporal-compare` for gesture detection now** | RuvSense already has a working DTW gesture matcher tuned to CSI signal scale. Swapping it for a generic `TemporalElement` matcher buys cleanliness but costs a re-tune and a new dep tree (`dashmap`, `lru`). Tracked as D5 for if/when a *second* DTW use case shows up. | +| **Adopt `midstreamer-scheduler` for the cluster-Pi aggregator** | The cluster aggregator does not currently exist as a real-time scheduler; ADR-039's tier scheduling is firmware-side. Until the host-side schedule appears, importing a deadline-aware scheduler is solution-looking-for-a-problem. Tracked as D6. | +| **Drop the `vendor/midstream` submodule entirely** | Cheap to keep, useful as the reference material this ADR cites. D7 keeps it on the explicit understanding that the pin is not advanced. | + +--- + +## 6. Open questions / re-evaluation triggers + +This ADR is `Rejected` today on the strength of the §1.1 / §3 analysis. The following events would justify re-opening it: + +1. **A second DTW / LCS / Levenshtein use case appears in RuView** (e.g. a CLI-side replay diff, a regression test fixture that needs sequence alignment, a TUI for pattern playback). Then re-evaluate `midstreamer-temporal-compare` per D5. +2. **A host-side real-time scheduler enters RuView's scope** (e.g. the cluster-Pi aggregator becomes responsible for slot timing instead of the ESP32 firmware). Then re-evaluate `midstreamer-scheduler` per D6. +3. **midstream ships a CSI-aware adapter or RF-scale `Sequence` extension** — i.e. midstream's own scope grows to include sensing primitives. As of the pinned commit (`30fe5eb`), this has not happened (zero matches for `csi|wifi|sensing|sensor` in `vendor/midstream/crates/*/src/*.rs`). +4. **RuView gains a QUIC-to-external-client requirement** that the WS fan-out cannot service (e.g. a mobile client over a lossy link that benefits from QUIC's stream priority + 0-RTT). Then re-evaluate `midstreamer-quic` per D1 / D4. + +If none of these triggers fire, this ADR stays Rejected and the carve-outs (D5, D6) remain optional. + +--- + +## 7.

The use case is now named: **real-time introspection of the CSI stream + low-latency detection of motion-shape events**, running as a parallel tap *alongside* RuView's existing event pipeline rather than replacing it. + +### 1.1 The latency floor today, by construction + +[`vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs:20`](../../vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs#L20) defines `WindowBuffer::new(max_frames: usize, max_duration_ns: u64)`. The events pipeline emits *only at window close*. At RuView's ~30 Hz CSI rate with the default 16-frame / 1-second windows, the soonest `MotionDetected` or `PresenceStarted` can fire is roughly **500–1000 ms after the actual RF perturbation**. That's an architectural floor, not an implementation accident — `WindowBuffer` is the integration tier, and integration takes time. + +For high-touch UI (the live dashboard) and for downstream consumers that need to react to motion *as it starts*, that floor matters. The `wifi-densepose-sensing-server` already maintains continuous per-frame state (`AppStateInner::{frame_history, rssi_history, smoothed_motion, baseline_motion, last_novelty_score}` at [`main.rs:307–423`](../../v2/crates/wifi-densepose-sensing-server/src/main.rs#L307)), but exposes them only as endpoint-poll scalars — there's no streaming-tap surface for "what's happening *inside* the pipeline right now". A consumer that wants reflex-level reaction has to invent it. + +### 1.2 What midstream's primitives actually map onto + +Ground-truth grep across `vendor/midstream/crates/`: + +| Term | Hits | Where | +|---|---|---| +| `Lyapunov` | 284 | `temporal-attractor-studio` | +| `LTL` | 230 | `temporal-neural-solver` | +| `Attractor` | 1252 | `temporal-attractor-studio` | +| `DTW` | 540 | `temporal-compare` | +| `phase-space` | 23 | `temporal-attractor-studio` | + +`temporal-compare/src/lib.rs:5` advertises *"Dynamic Time Warping (DTW), Longest Common Subsequence (LCS), Edit Distance (Levenshtein), Pattern matching and detection, Efficient caching"* — and the bench prose (in midstream's `README.md`) puts a cached pattern match at **~12 µs**. `temporal-attractor-studio/src/lib.rs:6` advertises *"Attractor classification (point, limit cycle, strange), Lyapunov exponent calculation, Phase space analysis, Stability detection"*. At RuView's ~30 Hz tick budget (33 ms), the per-frame cost of either is well under 1 % of the budget. + +### 1.3 Why this isn't ADR-214 + +ADR-214 (the V0 / Cognitum cluster correlator decision, owned in a separate repo) takes a much larger commitment: all five midstream crates, a full new `cognitum-rvcsi-correlator` crate, a `WireRecord` adapter layer, multi-Pi cadence alignment via `nanosecond-scheduler`. That's the right shape for V0 because V0 is filling a "no Rust correlator binary exists yet" gap (ADR-209 §C.1) — *replacing* a Python prototype. + +RuView's case is different and smaller. The Rust pipeline already exists and works. This ADR adds two midstream crates and one tap — same primitives, much narrower scope, no replacement. + +--- + +## 2. Decision + +**Adopt `midstreamer-temporal-compare` and `midstreamer-attractor` as a parallel real-time introspection tap inside `wifi-densepose-sensing-server`.** All eight decisions below are the architectural contract. + +### D1 — Only two midstream crates, no more + +`midstreamer-temporal-compare = "0.2"` and `midstreamer-attractor = "0.2"` enter as dependencies of `wifi-densepose-sensing-server`. The other three midstream crates are explicitly **not** in scope: + +* `midstreamer-scheduler` — sub-µs host-side scheduling has no fit in RuView; the per-Pi / per-ESP32 timing-sensitive work happens in firmware (ADR-073 channel hopping, the ESP32 TDM) where it belongs. +* `midstreamer-neural-solver` (LTL) — relevant for the MAT (Mass Casualty Assessment Tool) audit-trail use case, *not* for real-time introspection. Tracked as a follow-up ADR. +* `midstreamer-strange-loop` — long-horizon meta-learning for `adaptive_classifier` confidence; out of scope of "real-time". + +*Consequences:* the dependency footprint is two A+-security `unsafe_code = "deny"` crates, not the full midstream workspace. + +### D2 — The tap point is post-validate, parallel to `WindowBuffer::push` + +Each `CsiFrame` that survives `rvcsi_core::validate_frame` and `SignalPipeline::process_frame` (the same gate ADR-097 D6 establishes as the boundary) is fanned out to **two consumers**: + +1. The existing `WindowBuffer::push` → `EventPipeline` → `broadcast::` → `/ws/sensing` path. Unchanged. +2. The new `IntrospectionState::update_per_frame` → `broadcast::` → `/ws/introspection` path. Per-frame, never window-blocked. + +*Consequences:* zero behavioural change to the existing `/ws/sensing` / `/api/v1/sensing/latest` / vital-sign / pose / model-management endpoints; the bearer-auth middleware from #547 (PR-merged) wraps the new endpoint exactly like every other `/api/v1/*` and `/ws/*`. + +### D3 — One new WS topic + one new REST endpoint + +* `WS /ws/introspection` — continuous stream of `IntrospectionSnapshot` JSON frames (one per CSI frame received, modulo a small coalesce window if the client is slow). +* `GET /api/v1/introspection/snapshot` — one-shot poll for the latest snapshot (mirrors the existing `/api/v1/sensing/latest` shape). + +`IntrospectionSnapshot` carries: `timestamp_ns`, `regime` (one of `Idle`/`Periodic`/`Transient`/`Chaotic`), `lyapunov_exponent: f32`, `attractor_dim: f32`, `top_k_similarity: Vec<(signature_id: String, score: f32)>` (k = 5 by default). + +*Consequences:* dashboard widgets can subscribe directly; the existing `/ws/sensing` stays the canonical "events" topic; the new topic is the "continuous state" topic. + +### D4 — Per-frame update only, never window-blocked + +The new introspection path **must not** block on window close. The DTW path operates over a sliding tail buffer (default 64 frames) of derived feature vectors; the attractor path operates over a sliding tail of `mean_amplitude` scalars. Both update on every accepted frame. + +*Consequences:* the soonest "shape-matches signature" emission is bounded by the per-frame update cost (target ≤1 ms p99 on a Pi-5-class host), not by the 16-frame window — a **~16× collapse** of the latency floor on this specific class of event. + +### D5 — `temporal-neural-solver` (LTL) is out of scope of this ADR + +The MAT audit-trail use case (provable triggers with proof artefacts, ADR-style "this `SurvivorTrack` activation was provably (LTL formula) satisfied") is a separate concern. Tracked as a follow-up ADR; the same crate that lives in `vendor/midstream/crates/temporal-neural-solver` will be revisited there. + +*Consequences:* this ADR does not deliver audit-grade proof artefacts; if you need them, wait for the MAT ADR. + +### D6 — ESP32 firmware is unchanged + +Introspection runs entirely on the host side (`wifi-densepose-sensing-server`). The ESP32 ADR-018 wire format, the firmware's CSI collector, the TDM protocol, the NVS provisioning — none change. No firmware re-flash required to consume this feature. + +*Consequences:* deployment is "update the host-side binary / Docker image"; existing ESP32-S3 / ESP32-C6 / mmWave node fleets work as-is. + +### D7 — Signature library is JSON, on-disk, customer-owned + +A "signature" is a short labelled sequence of derived feature vectors. Schema (one file per signature under `--signatures-dir /etc/cognitum/signatures/`): + +```jsonc +{ + "id": "walking_slow_v1", + "label": "Walking — slow pace", + "captured_at": "2026-05-13T20:00:00Z", + "feature_kind": "amplitude_l2_per_subcarrier", // or "vec128" once an embedding source exists + "length": 64, + "dtw": { "window": 8, "step_pattern": "symmetric2" }, + "vectors": [ [ ... ], [ ... ], /* length-64 of feature vectors */ ], + "promotion_threshold": 0.78 +} +``` + +Three reference signatures ship under `signatures/` in the crate as developer fixtures (`idle_room.sig.json`, `walking_slow.sig.json`, `door_open.sig.json`). Customer-trained signatures are not committed. + +*Consequences:* the library is a deployment-time concern, not a build-time one; customers can tune the threshold per environment. + +### D8 — Measurement-first adoption — promotion bar is empirical + +Phase 0 spike measures the latency win against the existing `/ws/sensing` path on a recorded session. **Original aspirational bar: ≥10× p99 latency reduction on the "motion shape recognized" event class**, measured on at least one labelled recording. + +**Empirical baseline from `tests/introspection_latency.rs`** (I5/I6 — host-side L1 stand-in scoring + midstream-attractor regime classification on a 1-D mean-amplitude feature, 5-frame motion-ramp signature, 200 frames of noise warm-up, `analyze_every_n = 1`): + +| Signal | Frames to recognise | Ratio vs event-path floor (16) | +|---|---|---| +| `top_k_similarity[0].above_threshold` | 5 | **3.20×** | +| `regime_changed` (10-frame motion window) | did not fire | — | +| Per-frame `update()` p99 | **0.041 ms** (~24× under D4's 1 ms budget) | — | + +The 10× bar is **architecturally unreachable** at the 1-D scalar feature resolution this stand-in operates at — `signature_score`'s length-normalised L1 needs roughly the full signature length of in-shape frames to discriminate from noise (any shortcut trades false positives), and the attractor's Lyapunov classification needs more than a 10-frame perturbation to overcome a long noise trajectory. The 3.2× ratio is the structural ceiling for this feature class. + +**Closing the gap to 10× requires multi-dim features — specifically the `vec128` embeddings from ADR-208 Phase 2 (Hailo NPU)** — where partial matches become statistically distinguishable from noise after 1–2 frames, not 5. Until then, the adoption decision **revises the bar**: + +* **Ship behind `--introspection` (off by default)** until either ADR-208 P2 lands a multi-dim feature path, *or* the L1 stand-in is replaced with a numeric DTW that scores partial-prefix matches at acceptable false-positive rates. +* The per-frame `update()` cost bar (D4: ≤1 ms p99) **is met** — the feature is cheap enough to carry dark today. +* **Two parallel signals** in the snapshot (`top_k_similarity` for shape match, `regime_changed` for trajectory shift) cover different latency / robustness trade-offs — neither alone clears 10× on a 1-D scalar, but they cover complementary use cases. Downstream consumers pick. + +> **Side finding on midstream's `temporal-compare::DTW`**: its DTW uses *discrete equality* cost (0/1 between elements), not numeric distance — it's designed for LLM token sequences. On `f64` amplitude values, that scoring would be strictly worse than the L1 stand-in (every cell costs 1, no useful gradient). "Swap in midstream's DTW" — implied in earlier revisions of this ADR and proposed in I5/I6 — therefore isn't the optimization that closes D8. A *numeric* DTW would need to be hand-rolled or pulled from a different crate; tracked as a P1 follow-up alongside ADR-208 P2. + +*Consequences:* the kill switch is real (off-by-default CLI flag); the architectural value (continuous-state introspection surface + a per-frame regime signal + a cheap shape-match probe + a verified ≤1 ms update budget) ships, with the *latency-win* bar deferred to when multi-dim features arrive. + +--- + +## 3.

Implementation phases + +| Phase | Scope | Bar | +|---|---|---| +| **P0 — Spike + benchmark** | Add deps, scaffold `introspection.rs`, wire the tap, add `/ws/introspection`, measure p50/p99 latency on a recorded session. | ≥ 10× p99 latency reduction on the "shape recognized" path vs. `/ws/sensing` event path. If miss, the feature stays behind a CLI flag. | +| **P1 — First real signature library** | Capture 3 labelled segments (`idle_room`, `walking_slow`, `door_open`) on the ESP32-S3 on COM7, build the developer fixture under `signatures/`. | A live person walking in front of the node produces a `walking_slow` match in /ws/introspection ≥1 frame before `MotionDetected` fires on /ws/sensing. | +| **P2 — Dashboard widget** | Add an "Introspection" panel to the live dashboard subscribing to `/ws/introspection`: regime indicator, Lyapunov gauge, top-k matches with confidence. | Visual confirmation of D4 ("never window-blocked") — the panel responds to a perturbation before the `MotionDetected` toast appears. | +| **P3 — Signature capture workflow** | CLI sub-command `rvcsi capture-signature --label --duration 2s --out signatures/.json` (or its sensing-server equivalent) that records and labels a segment in one step. | A non-developer can extend the library without writing JSON by hand. | +| **P4 — Adaptive classifier hook (optional)** | Feed introspection's continuous regime scalar + top-k similarities into the existing `adaptive_classifier` as auxiliary features. | Measurable classifier accuracy improvement on a held-out test set; if no improvement, abandon and document. | + +P0 is the commitment. P1–P3 are sequential per-PR follow-ups. P4 is research-shaped and explicitly failure-tolerant. + +--- + +## 5. Consequences + +**Positive** + +* Soonest-event latency on the "shape recognized" path drops from ~533 ms (16-frame window @ 30 Hz) to ~33 ms (one frame at 30 Hz) — a 16× collapse, dwarfed only by network RTT and the DTW math itself (~12 µs / cached pattern). +* Dashboards and downstream consumers get a streaming-tap surface for *what the pipeline is seeing right now*, not just summary scalars at endpoint-poll time. +* `adaptive_classifier` and the novelty bank gain a richer per-frame feature input (regime, Lyapunov, top-k similarity) — augmenting, not replacing, their current inputs. +* Zero behavioural change to existing endpoints, no firmware change, no schema migration. Pure addition. +* Two A+-security `unsafe_code = "deny"` crates — bounded, audited dependency footprint. + +**Negative** + +* Dependency surface grows by two crates. Mitigation: both pinned `^0.2`, both ours (user owns midstream), both `unsafe_code = "deny"`. +* The DTW path is only as good as its signature library — a poor library means false matches. D7's per-deployment library + D8's `promotion_threshold` per signature mitigate; P3's capture workflow makes the library tractable to grow. +* Adding a second broadcast topic adds memory pressure under fan-out (each subscriber holds a ring slot). The default ring size (32 snapshots) caps it. + +**Neutral** + +* Existing `/ws/sensing` consumers continue to see the same events at the same cadence. +* ADR-097's rvCSI adoption is unaffected — this tap *consumes* rvCSI's validated `CsiFrame` output, doesn't replace any rvCSI seam. +* The `vendor/rvcsi` submodule and the `vendor/midstream` submodule both stay; this ADR uses crates.io versions of both for the build, with the submodules as reference / patch escape hatches (ADR-097 D7 and ADR-098 D7 patterns respectively). + +--- + +## 6. Alternatives considered + +| Alternative | Why not | +|---|---| +| **Tighten the rvCSI `WindowBuffer` to 1-frame / 0 ms windows.** | Defeats the purpose — `EventPipeline`'s state machines (`PresenceDetector::enter_windows = 2`, `MotionDetector::debounce_windows = 2`) need stable window-aggregated input to debounce noise. Single-frame windows produce per-frame events with no hysteresis, which is *worse* than today, not better. | +| **Write the DTW + attractor math from scratch in `wifi-densepose-signal`.** | This is what midstream's crates *are*. ~640 hits for DTW and 1252 for Attractor across midstream's existing source — re-implementing would be 1–2k LOC of math we'd own and maintain forever. Not free. | +| **Use the heuristic `smoothed_motion` / `baseline_motion` as the introspection signal.** | They already exist (`main.rs:310,377`), they're already broadcast on the dashboard's continuous-summary path. But they're a single scalar derived from EWMA — they don't classify regime, don't match shapes, don't give phase-space stability. Worth keeping as the "always-on lite indicator"; not a substitute for D3's snapshot. | +| **All five midstream crates at once.** | The other three (`scheduler`, `neural-solver`, `strange-loop`) don't fit the "real-time introspection" framing — they fit "host-side hard scheduling", "audit-grade proofs", "long-horizon meta-learning". Mixing them in would balloon the surface and dilute the latency-win measurement. D1 keeps it to two. | +| **Defer until ADR-214's V0 correlator ships and copy its design.** | V0's correlator is the *replacement* shape (Python prototype → Rust). RuView's case is the *addition* shape. The designs share crates but not topologies; deferring would leave RuView's latency floor in place for months while V0 lands. | + +--- + +## 7. Open questions + +* **Feature vector for `vec128`-class DTW.** Until ADR-208 Phase 2 ships real Hailo NPU embeddings, the per-frame feature vector is a derived scalar tuple (RSSI + per-subcarrier amplitude L2 norm). When the encoder lands, the DTW path consumes `vec128` directly — what version-skew strategy do signature libraries use? +* **Coalesce window for slow WS clients.** A subscriber falling behind shouldn't make the broadcast ring grow unboundedly. Default proposal: drop oldest, log a `warn!` after N consecutive drops. The exact N is tunable. +* **Cross-node introspection.** Today the snapshot is per-node. For multi-node deployments, do we want a fused cluster-level snapshot too? Likely yes — but as a separate ADR; this one keeps to per-node. + +--- + +## 8.

Air-gapped deployments must use `--no-edge-registry`. +- Stale-but-served behaviour can mask upstream outages from operators. Mitigation: include `stale: true` + `fetched_at` in the response so the UI can render a "registry possibly out of date" badge. + +### Risks + +- **Upstream rug-pull**: if `cognitum-apps` is deleted or replaced, the endpoint goes dark. The `--edge-registry-url` flag lets operators repoint without a code change. Long-term, RuView could mirror the registry into its own GCS bucket if the relationship requires it. +- **Cache poisoning**: the upstream is public-read; an attacker who breaches Cognitum's GCS write could push a bad registry. The cog-level signatures (ADR-100) limit the blast radius — bad registry entries can't install bad binaries, only show wrong metadata. Acceptable until registry-level signing lands. + +## Security review + +A real review of the attack surface this endpoint introduces. + +### Threats considered + +| # | Threat | Mitigation in this ADR | +|---|--------|------------------------| +| T1 | **SSRF** — operator-supplied `--edge-registry-url` redirects fetches to an internal target | Flag is operator-only (CLI / env) — there is no API endpoint to mutate it at runtime. Operators are already trusted (they control the binary). | +| T2 | **Outbound dependency reveals deployment** — a passive observer of the egress sees the appliance phoning home to GCS | Documented in the docstring + the runtime startup log. Operators wanting offline deployments use `--no-edge-registry`. | +| T3 | **Malicious upstream registry** — Cognitum's GCS bucket is breached and a poisoned `app-registry.json` is served | Two layers absorb this: (a) the registry's role is **discovery only** — installs verify the per-cog `binary_sha256` + `binary_signature` (ADR-100); a wrong description string can mislead a human, but a wrong binary still has to pass Ed25519 against `COGNITUM_OWNER_SIGNING_KEY`. (b) The endpoint exposes `upstream_sha256` so a paranoid operator can pin the expected registry hash externally and alert on drift. | +| T4 | **Response inflation** — upstream returns a multi-GB payload to exhaust memory | `MAX_PAYLOAD_BYTES = 8 MiB` cap (current registry is ~50–200 KB). Exceeding cap returns an error without buffering past the cap. | +| T5 | **Slow upstream blocking server threads** — Slowloris-style stall on the fetch | 10-second wire timeout via `ureq::AgentBuilder`. Per-handler fetch runs inside `tokio::task::spawn_blocking` so a stalled fetch never blocks the async runtime. | +| T6 | **Denial via `?refresh=1` abuse** — unauthenticated callers force-bypass the cache repeatedly | Cache lives in process; `?refresh=1` triggers a single upstream fetch behind a synchronous code path. A flood of refresh requests is rate-limited by the upstream's own throttling (GCS) and locally serialised by Rust's `RwLock`. Refresh requests are logged at `debug` so abuse is visible. **Follow-up:** add per-IP rate-limit middleware if seen abused (separate PR; tracked in #574-style follow-up). | +| T7 | **JSON deserialisation panics** — malformed registry triggers a Rust panic | Payload is parsed as `serde_json::Value` (opaque untyped tree) — never coerced into a strongly-typed struct that could panic. Failure is propagated as `FetcherError::Network` which the handler maps to 503. | +| T8 | **Stale-on-error masks outages from operators** | Response carries `stale: true` + `fetched_at` (unix timestamp). UI rendering MUST surface this badge — encoded as an explicit field, not an implicit silence. | +| T9 | **TLS downgrade / MITM on the fetch** | `ureq` is built with the `tls` feature (rustls) by default. No `--insecure` flag exists. If the upstream uses LetsEncrypt the cert chain is system-trusted; certificate pinning is out of scope (would block the bucket from rotating certs). | +| T10 | **Unauthenticated access exposes ‘what cogs exist’** | The registry is canonical-public information (already public-read on GCS via anonymous HTTP GET). Surfacing it on a local LAN HTTP API does not increase its disclosure. The endpoint stays under the project's existing `RUVIEW_API_TOKEN` Bearer auth — when set, the registry is gated like other `/api/v1/*` routes. | +| T11 | **Configuration injection via env var** — `RUVIEW_EDGE_REGISTRY_URL` set to a malicious URL by an attacker who controls the process environment | If an attacker controls the env, they own the process; this is not a new threat surface. Documented in the CLI help. | +| T12 | **Cache mutation across threads / poisoning** | The cache is `RwLock>`. Writes go through `cached.write()` once per fetch. Snapshot reads `clone()` the `CachedEntry` (cheap — `Value` is reference-counted internally for large strings) so concurrent readers don't share mutable state. Tests cover the multi-call path; no `unsafe` is used. | + +### What this ADR does NOT secure + +- **Registry-level signing** — the JSON payload itself is unsigned. If/when Cognitum's publisher pipeline emits a registry sig (e.g. detached `.json.sig`), a follow-up ADR will require it. Today the per-cog binary signature (ADR-100) is the actual trust root for installs; the registry is metadata. +- **Per-client rate-limiting on `?refresh=1`** — relies on the upstream's own throttling. If we see abuse we'll add a token-bucket middleware; not needed for v0.0.1. + +### Testing + +| Test | What it verifies | +|------|------------------| +| `first_call_hits_upstream_and_caches` | Single fetch, then cache hit | +| `ttl_expiry_triggers_refetch` | Cache TTL bound respected | +| `force_refresh_bypasses_fresh_cache` | `?refresh=1` semantics | +| `stale_serve_on_upstream_failure_after_cached_success` | T8 explicit (`stale: true` returned) | +| `no_cache_no_upstream_returns_error` | T3/T5 — error propagated cleanly when nothing to fall back on | +| `upstream_invalid_json_is_treated_as_error` | T7 — malformed payload doesn't panic | +| `upstream_sha256_is_deterministic` | T3 — hash field is reliable for external pinning | + +All 7 tests in `src/edge_registry.rs::tests` pass. + +## Migration + +1.

The published number is therefore not directly attainable, but the **architectural gap** is large enough that a learned-counter approach on our hardware should comfortably beat today's slot heuristic — and the infrastructure to train one already exists in this repo (Candle + RTX 5080 trained `pose_v1.safetensors` in 2.1 s yesterday — see [`docs/benchmarks/pose-estimation-cog.md`](../benchmarks/pose-estimation-cog.md)). + +Five primitives we already have but don't yet compose into a counter: + +1. **Paired CSI + camera label dataset** — `scripts/collect-ground-truth.py` + `scripts/align-ground-truth.js` (PR #641 streaming-safe). 1,077 samples currently; #645 tracks the path to ~30K. +2. **Stoer-Wagner min-cut for person-separable subcarrier groups** — `ruvector-mincut` (already a workspace dep). The Candle trainer used it yesterday and reported `Min-cut value: 0.1538 — partition: [55, 1] subcarriers`. +3. **Contrastive-pretrained CSI encoder** — `ruvnet/wifi-densepose-pretrained` on HF (12.2M training steps, 60K frames, 128-dim embeddings, ~165k emb/s on M4 Pro). +4. **Candle training pipeline** — proven yesterday: 400 epochs in 2.1 s on RTX 5080, bit-perfect ONNX export, signed cog binary on GCS. +5. **Multi-node fusion stage** — `multistatic_bridge.rs` already aggregates per-node feature vectors with the tunable `dedup_factor`.

Counts are integer-valued; classification gives a calibrated probability per count and lets the confidence head produce a meaningful uncertainty. +3. **Stoer-Wagner min-cut at fusion time, not training time.** We use the min-cut primitive to bound the per-node count from above (a node can't see more distinct people than the subcarrier graph has min-cuts), then take a confidence-weighted vote. +4. **Output is `{count, confidence, count_p95_low, count_p95_high}`**, not a single integer. Downstream consumers (Cogs / dashboard / alerts) can choose their certainty threshold. This is what closes the loop on the #499 UX: when the model is uncertain, the dashboard renders one stick figure with a "?" badge rather than two ghosts. +5. **No new hardware.** Same ESP32-S3 1×1 SISO that ships today. The win comes from learned features + multi-node fusion, not from bigger antennas. + +### Training (Candle / RTX 5080 / proven path) + +Same exact pipeline that produced `pose_v1.safetensors` yesterday.

No new data collection campaign required to bootstrap; we can train tomorrow on the same 1,077 samples that produced `pose_v1`. + +### Multi-node fusion + +The per-node count head + confidence head emit a categorical distribution over `{0..7}`. With N nodes, we have N such distributions plus N confidence scalars. Two fusion paths: + +- **Confidence-weighted log-sum** (Bayesian product): `log p_fused(k) = Σ_n c_n · log p_n(k)`. Simple, no extra parameters, comes from the optimal-expert combination literature. +- **Stoer-Wagner upper bound**: build a graph where edges are pairwise subcarrier-feature similarities between nodes. Min-cut size = a hard upper bound on the number of distinct people the node mesh can resolve. Clip the per-node-fused distribution to support `{0..min-cut}` before re-normalising. This is exactly what `ruvector-mincut` was added to the workspace for — it's been waiting for a counting consumer. + +Both fuse cleanly. v0.1.0 ships the log-sum; v0.2.0 adds the min-cut clipper after the first round of evaluation. + +### Why this beats today's heuristic + +| Failure mode of today's slot heuristic | How the learned counter avoids it | +|---|---| +| #499 — fixed denominators clamp → one person renders as 2+ groups | Encoder produces a fixed-dim embedding; the count head is invariant to feature magnitude, only to feature **shape** | +| `dedup_factor` per-room tuning is operator-visible toil | Count head's softmax is a learned per-room normaliser by construction | +| Adding nodes makes the count noisier under the slot heuristic | Multi-node fusion is **additive in confidence**, so each node either reduces uncertainty or stays neutral — never amplifies it | +| No per-frame uncertainty signal | `confidence` + `count_p95_low/high` exposed in every emit | +| Catastrophic failure on novel environments | LoRA per-room adapter (per ADR-079 P9 plan) hot-swappable without retraining | + +### Acceptance gates + +| Gate | v0.1.0 (initial release) | v0.2.0 (after data scaling) | +|------|--------------------------|------------------------------| +| Day-0 deployment (no calibration) | ≥ 80% within ±1 on same-room test set | ≥ 90% within ±1 | +| Cross-room (held-out environment) | ≥ 60% within ±1 | ≥ 75% within ±1 | +| Mean Absolute Error | ≤ 0.6 persons | ≤ 0.4 persons | +| Per-frame confidence reflects accuracy | Spearman correlation `r ≥ 0.5` between `confidence` and `(predicted == true)` | `r ≥ 0.7` | +| Inference latency on Pi 5 (Cog) | < 5 ms / frame cold-start | < 5 ms / frame | +| Binary size on GCS | ≤ 4 MB (matches `cog-pose-estimation`) | ≤ 4 MB | + +`v0.1.0` is intentionally modest — it's bounded by data-collection scale (#645).

The count head learns from this noisy signal; mitigations include filtering by `MediaPipe confidence ≥ 0.7` before training, and weighting the loss by confidence (same trick used in `pose_v1`). +- **Encoder freezing too aggressive**: if 50 epochs of frozen-encoder training doesn't see the count head converge, unfreeze earlier. We have telemetry from `train_results.json` to make this call empirically. +- **Min-cut over-constrains** in single-person scenarios: when N=1 the subcarrier graph has min-cut = 1 trivially.

Reasons: + +1. The cog binaries are already signed, tested, and cross-compiled (ADR-100/101/103). Re-implementing inference in JS would duplicate that work and introduce a second model artifact to keep in sync. +2. The cog binaries handle model loading, ONNX dispatch, and Hailo HEF routing transparently — the MCP layer needs only to understand the JSON event schema. +3.

On parse failure, return `{ok:false, error: "unexpected cog output: …"}`. | +| **T6** | **Rate-limit bypass on `ruview_train_count`** — an agent calls `ruview_train_count` in a tight loop, spawning unbounded training processes | The MCP server maintains an in-process job registry. On `ruview_train_count`, if more than 3 jobs are `status:"running"`, return `{ok:false, error:"too many concurrent training jobs (max 3)"}`.

Personalisation requires training data, but the privacy framework from R14 + R3 explicitly forbids sending raw CSI off-device: + +1. R14 — *data stays on-device; only aggregate state passes integration boundaries* +2. R3 — *no cross-installation linkage of embeddings* + +These constraints rule out centralised training on user CSI. The standard answer is **federated learning** (McMahan 2017): each device trains locally; only model deltas (gradients or weight updates) leave the device. + +CSI has three properties that change the standard FedAvg recipe: + +1. **Non-IID data.** Each Cognitum Seed sees a different environment signature (R3) and different occupant set. Naive FedAvg drifts toward the most-represented environment. +2. **High-bandwidth raw data.** A 5-minute CSI capture at 100 Hz × 56 subcarriers × 3 antennas × complex64 = ~200 MB. Federation must work with model updates only (~1-10 MB per round for the LoRA-fine-tuned AETHER head). +3. **Adversarial node risk.** A compromised seed can poison the global model via crafted updates.

Local data is **never** transmitted off-device. +3. **MERIDIAN normalisation.** Before computing the delta, each node subtracts its per-room embedding centroid from the locally produced embeddings (env_sig removal, see R3). This makes deltas environment-agnostic. +4. **Delta compression.** Compute ΔW_i = W_T+1_i − W_T. Quantise to int8 + LoRA-rank decomposition (rank=8) → ~1 MB per delta. +5. **Byzantine-robust aggregation.** Coordinator uses **Krum** (Blanchard 2017) instead of FedAvg: pick the K-f deltas (where f = expected byzantine count) that have minimum L2 distance to all others; aggregate only those. Cuts off outliers that suggest poisoning. +6. **Multi-link consistency check (R7 extension).** Coordinator computes a Stoer-Wagner mincut on the inter-node update similarity graph. If a cut isolates more than 20% of nodes consistently across rounds, those nodes are flagged for human review. +7. **Global update.** W_T+1 = W_T + lr_global · Krum_aggregate(ΔW_i). +8. **Convergence check.** After every R rounds, evaluate on a held-out (locally-held) per-node validation set.

This gives stronger guarantees but degrades model accuracy by 5-15× for the same ε.

Reset model and restart? Stop federation indefinitely? Decision deferred to operations. +3. **Side-channel timing leaks.** A separate ADR (TBD) needs to cover constant-time inference and constant-time DP-noise sampling. +4. **Subject-level vs sample-level DP.** This ADR specifies sample-level.

Public keys are exchanged via a key-agreement service (cognitum-v0 cluster acts as PKI). +2. **Mask generation**: each installation computes pairwise random masks `m_ij = PRG(seed=DH(sk_i, pk_j))` shared with each peer installation `j ≠ i`. +3. **Local model delta computation**: as per ADR-105 step 4, then with ADR-106 layers 1–3 applied (primitive isolation, clipping, DP noise). +4. **Mask the delta**: each installation computes `masked_delta_i = delta_i + Σ_j sign(i, j) · m_ij` where sign is `+1` for `i < j` and `-1` for `i > j`. +5. **Upload masked delta**: each installation uploads `masked_delta_i` to the cross-installation aggregator. +6. **Aggregation**: the aggregator computes `aggregate = Σ_i masked_delta_i`. The pairwise masks cancel by construction, so `aggregate = Σ_i delta_i + 0`. The aggregator **never sees** any individual `delta_i`. +7. **Drop-out handling**: if some installations fail to upload, missing masks are reconstructed via threshold-Shamir secret sharing of `sk_i` among peers (Bonawitz §4). +8. **Cross-installation DP composition**: with N installations and per-installation noise σ_local, the cross-installation effective σ_cross = σ_local · √N (improvement from amplification by sampling). Cross-installation (ε, δ) budget composed via Moments Accountant. + +### Embedding-space rotation key + +Even after secure aggregation, the **aggregated model itself** could leak biometric information when used at any installation. To prevent cross-installation **re-identification** specifically (R3 + R15 binding constraints), each installation applies a **per-installation orthogonal rotation** to its embedding space: + +``` +embedding_local = R_i · embedding_global +``` + +Where `R_i` is a random orthogonal 128×128 matrix sampled once at installation setup and stored locally (never transmitted). The federation operates on the **rotated space**; outputs at installation `i` are unintelligible at installation `j` because they're in different rotated frames. + +This prevents the leaked-model attack: even if an adversary obtains the global model + raw CSI from installation `j`, they cannot project installation `i`'s biometric embeddings into the same space without `R_i`. + +### Privacy budget (cross-installation) + +With N installations each running σ_local = 1.0 (per ADR-106 standard profile), 50 federation rounds: + +| Quantity | Value | +|---|---:| +| Per-installation ε | 2.5 | +| Cross-installation effective σ | √N · σ_local = √10 · 1.0 ≈ 3.16 | +| Cross-installation ε after 50 rounds | **~1.5** | +| Strong-aggregation budget consumed | <30% of community soft-bound ε=10 | + +Tighter than the standard within-installation profile because cross-installation amplification reduces effective noise per round. **This is a win**: federating across installations actually improves privacy due to the amplification effect, *as long as the cryptographic protocol is implemented correctly*. + +### Bandwidth analysis + +Per round, N=10 installations: + +| Phase | Bytes per installation | Total | +|---|---:|---:| +| Public key exchange (once per round) | 32 B | 320 B | +| Pairwise mask seeds (DH) | 32 B × N | 3.2 kB | +| Masked delta upload | 1 MB | 10 MB | +| Aggregate broadcast | 1 MB | 10 MB | +| Drop-out reconstruction (worst-case 1 missing) | ~32 kB | ~32 kB | +| **Total per round per installation** | **~2 MB** | **~20 MB** | + +Per ADR-105's monthly cadence: 50-180 MB / month / installation (the within-installation number) plus ~20 MB / month / installation for cross-installation = **70-200 MB / month / installation total**.

The PIR has hardware debounce in its own front-end, so no software-side polling is needed in the LP domain. Measured budget: ~10 µA standby (limited by RTC peripheral leakage, dominated by the IO mux clamp circuitry). + +**Deferred (follow-up):** a true LP-core program (separate ELF built with the riscv32 LP toolchain via `ulp_embed_binary()`, polling at ~10 Hz with software 3-of-5 debounce + threshold comparator) is the right path when the wake source is a **noisy or analog** sensor — an accelerometer over LP-I2C, an LP-ADC reading a battery-voltage divider, or audio-level detection via the SAR ADC. That code lives in `lp_core/main.c` as a sub-project and pushes the standby budget down to the ~5 µA target. Tracked as a follow-up because the immediate seed-node deployment uses a PIR. + +In both cases the HP-side API stays the same: `c6_lp_core_arm()` configures the wake source, `c6_lp_core_hibernate_and_wait()` enters deep sleep, and the boot path checks `c6_lp_core_was_motion_wake()` on subsequent boots. Swapping ext1 for a real LP-core program is then a single-file change behind a Kconfig option. + +## 3. Consequences + +### 3.1 Wins + +- New publishable research surface (Wi-Fi-6 CSI human pose). +- Multistatic clock-sync solved without spending WiFi airtime on coordination. +- Deterministic CSI cadence available where the AP cooperates (TWT). +- Cognitum Seed always-on class roughly doubles practical battery life. +- S3 production path untouched — zero regression risk for shipped fleets. + +### 3.2 Costs + +- Second firmware target to maintain (build, test, release). Mitigated by all C6 code being `#ifdef`-gated and the S3 path remaining the default `idf.py build`. +- HE-LTF CSI subcarrier layout differs from HT-LTF — downstream consumers (`stream_sender`, the host aggregator, `wifi-densepose-signal`) must learn to handle a non-fixed subcarrier count per frame. +- 802.15.4 stack adds ~80 KB to the C6 binary. Fits in 4 MB partition with room to spare. +- TWT depends on AP cooperation. Most home APs (including the `ruv.net` AP visible in the C6 scan dump) don't support 11ax STA TWT yet — graceful fallback required. + +### 3.3 Verification + +- `firmware/esp32-csi-node` builds for both `esp32s3` (existing) and `esp32c6` (new) targets. +- S3 build artifact SHA-256 unchanged vs the last v0.6.x release (proves no regression in shared code). +- C6 build flashes to COM6, boots, joins WiFi, requests TWT (logs success or graceful NACK), initializes 802.15.4, emits CSI frames with the extended ADR-018 metadata. +- Cross-node time-sync demonstrated between two C6 boards with offset <100 µs measured via shared GPIO toggle and external scope. +- LP-core hibernation current draw measured via INA: target ≤5 µA average. + +## 4.

(2) Soft-AP HE module (`c6_softap_he.{h,c}`) runs the C6 in AP+STA mode with WPA2 + HE advertised so a second C6 STA can negotiate real iTWT against a known-cooperative AP (B1/B2 unblocker without buying an 11ax router).

The ADR-110 §2.4 ≤100 µs alignment target is **empirically met by the smoothed offset alone**. **(b) v0.6.9 sync-packet** (32-byte UDP, magic `0xC511A110`, every `CONFIG_C6_SYNC_EVERY_N_FRAMES` CSI frames) carries `(node_id, local_us, epoch_us, sequence)` so host can pair against incoming CSI frames. Live-verified §A0.12 — COM9 reports `local − epoch = 1 163 565 µs` matching §A0.10's measured boot delta within 285 µs. **(c) v0.7.0 ADR-018 byte 19 bit 4 wire-fix** — bit 4 now sourced from `c6_sync_espnow_is_valid()` (was only the broken 802.15.4 path). Mixed S3+C6 fleets correctly advertise sync via the working transport. **(d) Host-side decoders + wiring**: Python `SyncPacketParser` (6 tests) + Rust `SyncPacket` (10 tests, all green; `SyncPacket::apply_to_local` recovers per-frame mesh-aligned timestamps). Sensing-server `udp_receiver_task` magic-dispatches `0xC511A110` and stores `NodeState::latest_sync` + `NodeState::mesh_aligned_us(local_at_frame)` helper. **(e) IDF v5.4 upstream gap formally documented (§A0.6)**: full `components/esp_wifi/include/esp_wifi*.h` grep proves the public API exposes only STA-side iTWT/bTWT — no `esp_wifi_ap_set_he_config`, no `wifi_he_ap_config_t`.

Both ESP32-S3 (ADR-028) and ESP32-C6 (ADR-110) paths stay byte-identical. + +--- + +## 2. Decision + +Adopt a **dual-protocol** integration strategy: + +1. **Primary — MQTT + Home Assistant auto-discovery (HA-DISCO).** Add an MQTT publisher to `wifi-densepose-sensing-server` that connects to a user-supplied MQTT broker (default: `mqtt://localhost:1883`), publishes one HA-discovery message per capability per RuView node on startup and on periodic refresh (default 600 s), translates each WebSocket broadcast (`edge_vitals`, `pose_data`, `sensing_update`) into per-entity MQTT state messages, and honors a `--privacy-mode` flag that strips biometrics (HR / BR / pose keypoints) before publish. + +2. **Secondary — Matter Bridge (HA-FABRIC).** Expose RuView nodes as Matter Bridged Devices over WiFi so the **subset of capabilities Matter standardises today** — presence (`OccupancySensing`), motion (`BooleanState`), fall events (`SwitchCluster`-as-event), person count (numeric attribute on the bridge) — are consumable by **any Matter controller**: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant itself. Biometrics (HR/BR) and pose stay on MQTT until the Matter spec adds device types that can represent them. + +The two paths are **complementary, not alternative**: MQTT carries the full telemetry surface for power users; Matter carries the standardised subset for cross-ecosystem reach. A user running HA gets both — MQTT entities populate alongside Matter Bridged Devices and HA dedupes via `unique_id`. A user running Apple Home gets only Matter, but they get the presence/fall/count signals that matter most for automations. + +A **Home Assistant HACS Python integration** is sketched as a follow-on (§6.A) for users who don't run MQTT and want richer features than Matter exposes.

The bridge presents itself to Matter controllers as a **Bridged Devices Aggregator** (per Matter Core Spec §9.13) with one Bridged Device endpoint per RuView node, exposing the standardised subset of capabilities. Biometrics and pose are **not exposed** over Matter — they have no spec-defined clusters and cannot be soundly represented (covering them in `Generic Sensor` would force every controller to render them as nameless numbers). + +#### 3.11.1 Matter device-type mapping + +| RuView capability | Matter cluster | Endpoint device type | Source field | +|---|---|---|---| +| Presence | `OccupancySensing` (0x0406) | `OccupancySensor` (0x0107) | `edge_vitals.presence` | +| Motion (boolean above threshold) | `OccupancySensing` (0x0406) | (same endpoint) | `edge_vitals.motion > 0.1` | +| Fall event | `Switch` (0x003B) `MultiPressComplete` event | `GenericSwitch` (0x000F) | `edge_vitals.fall_detected` (one momentary press = one fall) | +| Person count | `OccupancySensing` extension attribute (vendor-specific 0xFFF1_0001) | (same endpoint) | `edge_vitals.n_persons` | +| Zone occupancy | one `OccupancySensor` endpoint per zone | (multiple endpoints) | `sensing_update.zones[*]` | +| RSSI / motion energy / presence score / breathing rate / heart rate / pose | **not exposed over Matter** | — | (MQTT only) | + +The vendor-specific person-count attribute uses RuView's CSA-assigned vendor ID (open question §9.9). Controllers that don't understand the vendor extension still see the standard `OccupancySensing.Occupancy` boolean — graceful degradation. + +#### 3.11.2 Commissioning + fabric model + +- **Commissioning over WiFi**: the bridge prints a Matter setup code (11-digit short code + QR string) to logs and to `--matter-setup-file ` on first start. User scans with Apple Home / Google Home / HA Matter integration. +- **No Thread radio required**: sensing-server runs on hosts (Pi 5, x86, Cognitum Seed) that have WiFi but no 802.15.4. Matter-over-WiFi is sufficient. Thread support is explicitly out of scope until ESP32-C6 firmware grows a Matter stack (separate ADR; see §7). +- **Multi-admin / multi-fabric**: the bridge accepts multiple commissioning sessions so a single node can be paired into Apple Home **and** Home Assistant **and** Google Home concurrently — Matter's `OperationalCredentials` cluster handles fabric isolation. +- **Resetting commissioning**: a `--matter-reset` CLI flag wipes stored fabric credentials so a node can be repaired against a new controller. + +#### 3.11.3 SDK choice (open in §9, sketched here) + +Three viable Rust paths: + +| Option | Pros | Cons | +|---|---|---| +| **`matter-rs`** (project-chip/rs-matter) — pure-Rust SDK | No FFI, no C++ build chain, fits our Rust-only crate policy, MIT-licensed | Less mature than C++ chip-tool; certification path less proven | +| **`project-chip/connectedhomeip`** via Rust FFI bindings | Reference implementation, every controller tested against it, certification-ready | Drags in CMake, C++ toolchain, ~50 MB of vendored code; clashes with our cargo-first build | +| **External Matter bridge process** (separate ESPHome-like daemon) | Decouples Rust crate from Matter SDK churn | Operational complexity; two processes to deploy | + +**Tentative**: `matter-rs` for v0.7.0 ship; fall back to chip-tool-FFI if cert blockers emerge. Final decision deferred to P7 spike. + +#### 3.11.4 Limitations to document upfront + +These are **deliberate**, not bugs — users must see them in `docs/integrations/matter.md` before pairing: + +- **No HR, BR, pose, RSSI over Matter.** Matter has no clusters for these. Use MQTT for biometric / detailed telemetry. +- **Fall events are one-shot.** A fall fires a momentary switch press; controllers must subscribe to the event (most do). +- **Person count is vendor-extension.** Apple Home / Google Home will show occupancy on/off; only HA and SmartThings (with custom handlers) will surface the count. +- **One fabric controller is "primary."** Automations split across fabrics can race; users should keep heavy automation logic in one controller (typically HA). +- **No video / image data ever.** Matter spec forbids it on these device types and we wouldn't expose it anyway. + +#### 3.11.5 Why this is "Works with HA" *and* "Works with everything else" + +A node paired into HA shows up in **two** ways: +- as a set of MQTT entities (HA-DISCO path) with full telemetry +- as a Matter device under HA's Matter integration with the standard subset + +HA dedupes by `unique_id` (we set both paths' IDs to `wifi_densepose__`), so users don't see ghost devices. The Matter device is the one Apple Home or Google Home will see if the user also pairs into those — same physical node, three controllers, no duplication. This is the architectural reason for adopting both protocols rather than picking one. + +### 3.12 Semantic automation primitives (HA-MIND) + +Raw signals are not the product. Customers don't want to *write a Node-RED flow that thresholds breathing rate at night to infer sleep*. They want a `binary_sensor.bedroom_someone_sleeping` they can wire directly into a "dim hallway light at 10 % if anyone's asleep" automation. Same for fall *risk*, distress, room activity, elderly inactivity, meeting-in-progress, bathroom occupancy. This is the inference layer that turns RuView from "RF sensing" into **ambient intelligence infrastructure** — and it has to ship as first-class HA entities and Matter events, not as a developer SDK. + +#### 3.12.1 Catalog of inferred primitives (v1) + +Each primitive is a fused state derived from one or more raw channels with a small finite-state machine. Inference runs inside `wifi-densepose-sensing-server` (same place MQTT publication runs), gated behind `--semantic` (default on; can be disabled). Each primitive has a confidence score and an explanation field so HA users can debug why it fired. + +| Primitive | Inputs (raw) | Output kind | Default true-condition | Hysteresis / refractory | +|---|---|---|---|---| +| **Someone sleeping** | presence + low motion (<5 % for ≥300 s) + breathing rate 8–20 bpm + low HR variability | `binary_sensor` (occupancy) | all conditions hold simultaneously | enters after 5 min; exits when motion > 15 % for ≥30 s | +| **Possible distress** | sustained elevated HR (>1.5× rolling baseline for ≥60 s) + agitated motion + no fall | `binary_sensor` (problem) + `event` | confidence ≥ 0.75 | latch for 5 min after exit | +| **Room active** | presence + motion > 10 % for ≥30 s in any 5-min window | `binary_sensor` (occupancy) | window-rolling | exits on 10 min idle | +| **Elderly inactivity anomaly** | no motion + presence stable for > N× rolling daily median idle (default 2×) | `binary_sensor` (problem) + `event` | model-personalised | per-resident baseline; alerts max 1×/day | +| **Meeting in progress** | person count ≥ 2 + sustained low-amplitude motion (sitting) + speech-band micro-motion if `speech_band` cog installed | `binary_sensor` (occupancy) | ≥2 ppl + ≥10 min | exits when person count < 2 for 2 min | +| **Bathroom occupied** | presence true in zone tagged `bathroom` | `binary_sensor` (occupancy) | zone+presence | privacy-mode keeps this enabled (it's not biometric) | +| **Fall risk elevated** | recent near-fall (sharp acceleration without confirmed fall) OR gait instability score > threshold | `sensor` (0–100) + `event` on threshold cross | model-derived | 24-hour window | +| **Bed exit (overnight)** | "someone sleeping" → presence transitions out of bed-tagged zone between 22:00–06:00 local | `event` | edge-triggered | one event per exit | +| **No movement (safety check)** | presence true + motion < 1 % for ≥ N minutes (default 30) | `binary_sensor` (problem) + `event` | duration threshold | clears on motion | +| **Multi-room transition** | track_id continuous across zones within 10 s | `event` (`who_went_from_to`) | edge-triggered | per-track event | + +Catalog v2 (deferred): "child playing", "pet vs human", "agitation gradient", "circadian phase". Owned by an ADR-1xx follow-on after the v1 primitives have field data. + +#### 3.12.2 Surface mapping across the three layers + +| Layer | How a semantic primitive shows up | +|---|---| +| **MQTT (HA-DISCO)** | New topic namespace `homeassistant/binary_sensor/wifi_densepose_//` and `homeassistant/event/wifi_densepose_//` — full discovery payloads including the explanation field as `json_attributes` | +| **Matter (HA-FABRIC)** | Standard cluster mappings: sleeping/active/meeting/bathroom → `OccupancySensing` (separate endpoints); distress/inactivity/no-movement/bed-exit/fall-risk-cross → `Switch.MultiPressComplete` events on dedicated `GenericSwitch` endpoints; fall-risk score → vendor-extension attribute on the bridge endpoint | +| **Home Assistant automations** | Ship 8 starter blueprints in P5: "Notify on possible distress", "Wake-up routine on bed exit", "Dim hallway on someone sleeping", "Alert on elderly inactivity anomaly", "Lights on for meeting in progress", "Bathroom fan on while occupied", "Escalate on fall risk crossing 70", "Auto-arm security when room not active" | +| **Apple Home scenes** | Each `OccupancySensor` endpoint and each `GenericSwitch` event triggers Apple Home scenes via Matter — user picks "When *bedroom someone sleeping* is on, run *night mode*" from the Apple Home UI directly. No HA required for this path | + +#### 3.12.3 Why these specific primitives + +These eight cover the **top automation requests from the smart-home market** without needing video or wearables: + +- **Healthcare / aging-in-place** — "elderly inactivity anomaly", "fall risk elevated", "possible distress", "no movement (safety check)", "bed exit (overnight)" — directly map to AAL (Active and Assisted Living) device-class expectations +- **Convenience automation** — "someone sleeping", "room active", "meeting in progress", "bathroom occupied" — the four highest-volume HA forum-requested binary states +- **Privacy** — none of these require biometric *values* to be published, only the inferred *states*. A `--privacy-mode` deployment can keep semantic primitives ON and still strip HR/BR/pose, because the inference happens server-side and only the state crosses the wire + +#### 3.12.4 Inference quality contract + +Each primitive ships with: +- A **published precision/recall** on a held-out test set built from ADR-079 paired captures + synthetic stress scenarios — committed to `docs/integrations/semantic-primitives-metrics.md` +- An **explainability payload**: every state change carries `reason: ["motion<5%", "br=12bpm", "presence=true"]` style attributes so HA users can debug +- A **confidence threshold**: per-primitive, user-tuneable via `--semantic-threshold-=` (default published in the metrics doc) +- A **suppression contract**: primitives never fire during the first 60 s after sensing-server start (warmup), and never during `csi_calibration_in_progress` states (per ADR-014) + +#### 3.12.5 Configuration + +``` +--semantic Enable inference layer (default: on) +--semantic-thresholds-file Per-primitive thresholds (defaults shipped) +--semantic-zones-file Zone-tag map (e.g. {"bathroom": ["zone_3"]}) +--semantic-baseline-window-days Days of history for personalised baselines (default: 14) +--no-semantic- Disable a specific primitive (repeatable) +``` + +#### 3.12.6 What this changes architecturally + +Inference lives in a new module `semantic_inference.rs` alongside `mqtt_publisher.rs` and `matter_bridge.rs`. It subscribes to the same `tokio::broadcast` channel everything else does, runs each primitive's FSM, and emits **two output streams**: + +1. A `SemanticState` event on a new broadcast channel that MQTT and Matter publishers both subscribe to (so the same inference drives both surfaces without duplication) +2. Append-only `semantic_events.jsonl` log under `--data-dir` for offline analysis + ADR-079 paired-capture supervision + +This means: **adding a new primitive is one file change**. No MQTT schema rev, no Matter cluster rev — just add the FSM, register it, and discovery/state publish flow through both surfaces automatically. + +--- + +## 4. Implementation phases + +| Phase | Scope | Status | +|---|---|---| +| **P1** | Add `mqtt` feature flag to `wifi-densepose-sensing-server` Cargo.toml (depends on `rumqttc = "0.24"`). Wire CLI flags (§3.8) into `cli.rs`. No publishing yet, just config plumbing + unit tests on flag parsing. | pending | +| **P2** | HA discovery message emitter. New module `mqtt_discovery.rs`. Emits all entity `config` topics on connect + every `--mqtt-refresh-secs`. Schema-validated against HA's published JSON schema. | pending | +| **P3** | State publication. Subscribe to internal `tokio::broadcast` channel (the one `tx.send(json)` writes to on line 3983 of `main.rs`). Translate `edge_vitals` / `sensing_update` / `pose_data` messages into per-entity state payloads. Apply rate-limit + privacy-mode filters. | pending | +| **P4** | Integration tests: dockerised mosquitto in CI (extend `.github/workflows/firmware-qemu.yml` pattern), schema-validate every emitted config against HA's `homeassistant/components/mqtt` JSON schemas (pin to a tested HA version). Add a smoke test that brings up sensing-server in `--source mock --mqtt`, subscribes with `paho-mqtt` test client, asserts on entity creation. | pending | +| **P4.5** | **Semantic inference layer (HA-MIND).** New module `semantic_inference.rs` implementing the 10 v1 primitives from §3.12. Output broadcast channel consumed by both MQTT publisher (P3) and Matter bridge (P8). Per-primitive precision/recall baselines published to `docs/integrations/semantic-primitives-metrics.md`. Unit tests per FSM + integration tests via replay of ADR-079 paired captures. | pending | +| **P5** | Docs: new `docs/integrations/home-assistant.md` with screenshots of the HA UI after auto-discovery completes, example HA dashboard YAML (Lovelace card configs), 8 starter blueprints from §3.12.2 (distress notify, wake routine, hallway dim, elderly anomaly alert, meeting lights, bathroom fan, fall-risk escalate, auto-arm security), and the raw-channel example automations: "turn on hall light when presence ON", "send notification on fall_detected event", "log HR/BR to InfluxDB". | pending | +| **P6** | Ship `--mqtt` in the next sensing-server release (target: v0.7.0). Demo end-to-end on `cognitum-v0` against a Mosquitto add-on running on a Home Assistant OS install. Update README hardware-options table with "Works with Home Assistant" badge. | pending | +| **P7** | Matter Bridge spike: build a throwaway prototype with `matter-rs` exposing one `OccupancySensor` endpoint + one `GenericSwitch` for fall. Pair against Apple Home, Google Home, and HA's Matter integration. Decision gate: if pairing works on all three, proceed to P8; if blocked, switch to chip-tool FFI and re-spike. | pending | +| **P8** | Matter Bridge production. Implement `--matter`, `--matter-setup-file`, `--matter-reset`, `--matter-vendor-id`, `--matter-product-id` CLI flags. Aggregator + Bridged Devices for all RuView nodes; per-zone occupancy endpoints; fall as `MultiPressComplete` event; person count as vendor-extension attribute. Integration tests via chip-tool sim. | pending | +| **P9** | Multi-controller validation. Pair one Cognitum Seed + 3 child ESP32 nodes simultaneously into HA, Apple Home, and Google Home. Verify presence flips on all three within 1 s of a real motion change. Document the multi-admin flow in `docs/integrations/matter.md`. | pending | +| **P10** | CSA Matter certification path (optional, ADR-1xx follow-up). Decide cost vs marketing value of the official "Matter-certified" badge ($3 k/year CSA membership + per-product test fees). Sketch only — production decision deferred. | pending | + +Each phase ends with a checkbox PR. The ADR is updated with actual artifacts (commit hashes, screenshots, witness bundle entries) as phases land. **P1–P6 (MQTT) and P7–P10 (Matter) run in parallel after P6 lands** — they share no code, so a Matter regression cannot break the MQTT path and vice versa. + +--- + +## 5. Consequences + +### 5.1 Wins + +- Zero-code UX for HA users — discovery handles the entire onboarding. +- **Cross-ecosystem reach via Matter** — Apple Home / Google Home / Alexa / SmartThings users can adopt RuView without ever running HA, expanding our addressable market by ~4×. +- Decouples RuView from its own UI; users can build their own dashboards in HA / Grafana / Node-RED on the same MQTT firehose. +- Adds a `--privacy-mode` flag that gives operators a single-knob biometric strip for compliance contexts. +- Matter fabric isolation is a privacy win by construction — biometrics are out-of-spec for the exposed clusters, so a buggy controller can't accidentally exfiltrate them. +- Webhook + future HACS path stay open (§6) — no lock-in. +- Establishes our presence in the HA ecosystem AND the broader Matter ecosystem (community add-on lists, blueprints, forum recipes, App Store / Play Store visibility via Apple Home / Google Home device listings). + +### 5.2 Costs + +- New runtime dependency (`rumqttc`) in `wifi-densepose-sensing-server`. Mitigated by feature-flag (`mqtt`), default off; users who don't enable `--mqtt` pay zero binary or runtime cost. +- **Matter SDK dependency** (`matter-rs` tentatively) gated behind `--matter` feature flag. Adds ~5 MB to release binary when enabled; zero cost when disabled. Tracking CSA spec churn is a real ongoing cost. +- One more thing to maintain across HA breaking changes. HA commits to the `homeassistant//.../config` schema being stable (their published policy), but historically they have evolved fields like `availability_topic` → `availability` (list-of). We'll pin to a tested HA version per release and call out tested-against in `docs/integrations/home-assistant.md`. +- **Matter spec churn** — Matter 1.0 → 1.3 added device types and changed cluster IDs. We pin to a tested Matter spec version per release. Annual re-validation overhead. +- Requires CI infra: a mosquitto container in workflow, schema-validation against HA schemas, **and** a chip-tool simulator for Matter pairing tests (need to vendor or fetch). +- CSA membership ($3 k/year) is required to obtain a permanent vendor ID; until then we use the development VID `0xFFF1`. Production deployment past P9 requires the membership decision (§9.9). + +### 5.3 Verification + +Acceptance criteria are §8.

Alternatives considered + +### 6.A Custom HA integration (HACS) — *follow-on, not primary* + +Rough sketch: + +- Separate Python repo (proposed name: `ruvnet/hass-wifi-densepose`). +- Talks to sensing-server's existing WebSocket at `/ws/sensing` and REST at `/api/*`. +- Config-flow UI in HA: user enters server URL + bearer token; integration discovers entities. +- Distribution via HACS (https://hacs.xyz), requires HACS review + acceptance. + +**Effort estimate:** ~4–6 weeks (vs ~2 weeks for §2 MQTT path). Adds a Python codebase to maintain in a Rust-first org. Pays off in two scenarios: + +1. Users who run HA but don't run an MQTT broker (rare but exists). +2. Users who want sensing-server features that don't map cleanly to MQTT (e.g. live pose video preview). + +**Plan:** revisit after P6 lands and we have real adoption data on the MQTT path. If MQTT covers 80%+ of installs, HACS becomes a nice-to-have. If not, it becomes ADR-1xx follow-up. + +### 6.B Local-push REST webhook — *rejected* + +- sensing-server `POST`s to HA's webhook endpoint (`/api/webhook/`). +- Trivial to implement (~2 days). + +Rejected because: + +- One-way only — no `set_state` / arm / disarm path back. +- No entity discovery — user has to manually create input_booleans / sensors / template_sensors in HA YAML. +- No availability / LWT — sensing-server going offline is invisible to HA. +- Fails the "plug-and-play" bar that #574 / #760 set. + +Documented here so future readers know we considered it. + +### 6.C mDNS discovery (#574) — *complementary, not competing* + +mDNS / Zeroconf lets HA (or any local client) discover sensing-server's IP without manual configuration. It's orthogonal to MQTT: we should add it (already tracked in #574) so the user doesn't have to type the broker host either. mDNS resolves *where the broker is*; MQTT auto-discovery resolves *what entities to create*. Both ship; neither blocks the other. + +--- + +## 7.

Sensing-server resolves the friendly name from local config and injects into MQTT/Matter device labels. +7. **Pose keypoint schema.** ✅ **COCO 17-keypoint order.** Index → joint name mapping documented in `docs/integrations/home-assistant.md` and re-exported as `wifi_densepose_core::pose::COCO17`. +8. **Multi-node aggregation.** ✅ **4 children + 1 parent via `via_device`.** Easier to debug; matches §3.4. + +### 9.B Matter path (P7–P10) + +9. **Matter vendor ID.** ✅ **Dev VID `0xFFF1` through P9.** CSA membership decision gate at P10 (deferred; sketched only). +10. **Matter SDK.** ✅ **Start with `matter-rs`.** Fall back to chip-tool FFI only if cert blockers emerge in P7 spike. +11. **Matter Thread.** ✅ **Future ADR.** ADR-115 stays WiFi-only on the server side. Thread support from ESP32-C6 firmware is a separate ADR after C6 stabilises (post-ADR-110 P8). +12. **Fall event mapping.** ✅ **`Switch.MultiPressComplete`.** Cleaner semantics for controllers; matches Apple Home / Google Home rendering expectations. +13. **Person count.** ✅ **Vendor extension.** Do not kludge into fake endpoints. Apple Home / Google Home will show `Occupancy: ON/OFF` only — that's honest. HA and SmartThings will surface the count via the vendor-extension attribute. + +### 9.C Open-after-9 (new questions raised post-ACK) + +Empty as of 2026-05-23.

Context + +ADR-115 shipped the Home Assistant + Matter integration as a **`--mqtt` flag on `wifi-densepose-sensing-server`** — a Rust binary that runs on a Pi / Linux box, consumes UDP frames from the ESP32 fleet, and publishes MQTT for any Home Assistant install to discover. That works, but it makes HA+Matter a *configuration of the aggregator*, not an *installable artifact* a Cognitum Seed user can drop into their existing fleet. + +The Cognitum Seed already has a [105-cog catalog](https://seed.cognitum.one/store) — packaged Seed apps (`cog-pose-estimation`, `cog-quantum-vitals`, `cog-person-matching`, etc.) that anyone can install from `app-registry.json`. **There is no `cog-ha-matter` yet.** That's the gap this ADR closes. + +The cog packaging precedent is ADR-101 (`cog-pose-estimation`) which ships signed aarch64 + x86_64 binaries on GCS with a `pose_v1.safetensors` weight blob — same shape we'd want for the HA cog. + +### 1.1 Why a cog, not just the existing flag? + +| Path | Distribution | Discovery | Update | Witness | Local AI | +|---|---|---|---|---|---| +| `--mqtt` on `sensing-server` | manual install of the Rust binary | none | manual | none | external | +| **`cog-ha-matter` Seed cog** | `app-registry.json` listing, one-click install | mDNS / cog browser | OTA via cog runtime | Ed25519 witness chain | local ruvllm + RuVector | + +The cog ships HA+Matter as a first-class Seed feature — same UX as installing a pose estimator or person matcher. + +### 1.2 What this ADR is *not* + +- Not a deprecation of the `--mqtt` flag on sensing-server. The flag stays for Pi / Linux deployments without a Seed; the cog is the Seed-native option. +- Not a port of HA-MIND / HA-DISCO logic to a different language. The Rust crate already exists; the cog *wraps* it as a Seed-installable artifact + adds Seed-specific surfaces (witness, RuVector, ruvllm-driven thresholds). +- Not a Matter SDK ship. ADR-115 §9.10 deferred the matter-rs SDK wiring to v0.7.1; this ADR continues that deferral and focuses on the *cog packaging* + *first-class Seed integration*, with Matter Bridge mode shipping in v0.8 once the SDK is ready. + +## 2. Decision (provisional — to be refined by the research dossier) + +Build **`cog-ha-matter`** as a Cognitum Seed cog with these surfaces: + +### 2.1 Core entity surface (unchanged from ADR-115) + +The cog republishes the same 21 entities per node (11 raw + 10 semantic primitives) over MQTT auto-discovery, so HA installations behave identically whether the source is a Seed cog or an external sensing-server. + +### 2.2 Seed-native enhancements + +- **Self-contained MQTT broker (optional)** — if the user doesn't already run mosquitto, the cog can host an embedded broker on `cognitum-seed.local:1883` and act as the HA endpoint directly. +- **mDNS service advertisement** — `_ruview-ha._tcp` so HA's discovery integration finds the Seed without manual config. +- **RuVector-backed semantic-primitive thresholds** — instead of static `semantic-thresholds.yaml`, the cog learns per-home thresholds via a SONA-adapted RuVector model (matches the Seed's local-first AI story). +- **Ed25519 witness chain** — every state transition logged with a Seed signature so care-home / regulated deployments can audit decisions. +- **OTA firmware coordination** — the cog manages C6 firmware updates for ESP32-C6 nodes in the mesh (ADR-110 substrate). + +### 2.3 Matter dimensions (depend on research findings) + +The research dossier covers (a) Matter Bridge vs Matter Device mode, (b) Thread Border Router on the Seed's ESP32-S3 (if feasible), (c) CSA certification path, (d) which Matter device classes map cleanly to which entities. **Decision deferred** until the dossier lands; this ADR will be updated in §3 with the specific Matter feature set. + +### 2.4 Multi-Seed federation + +Multiple Seeds in adjacent rooms coordinate via: +- ESP-NOW mesh (ADR-110 substrate) for time alignment +- mDNS for service discovery +- Witness chain replication for cross-Seed event provenance + +The federation model is the natural extension of ADR-110's mesh substrate into the application layer. Specifically: ADR-110 gives us ≤100 µs cross-board sync; this ADR uses that to deduplicate cross-Seed events (one fall, one alert) and reconstruct multi-room transitions (one occupant, room A → hallway → room B). + +## 3. Research dossier findings (P1 complete) + +Full dossier: [`docs/research/ADR-116-ha-matter-cog-research.md`](../research/ADR-116-ha-matter-cog-research.md). The eight research questions are now answered: + +1. **Matter Bridge vs Matter Root** — Matter 1.4 introduced `OccupancySensor (0x0107)` with `RFSensing` feature flag on cluster `0x0406` (revision 5 in Matter 1.4). That's the correct device class for WiFi-CSI sensing — no health/vitals cluster exists in Matter 1.4.2 and won't soon. **Seed acts as Bridge** with N dynamic OccupancySensor endpoints, **not Commissioner** (the C6 sensing nodes stay Accessories only — 320 KB SRAM no PSRAM rules out commissioning). +2. **Thread Border Router** — ESP32-C6 single-chip TBR confirmed working; `CONFIG_OPENTHREAD_BORDER_ROUTER=y` is the only config step. ADR-110's `c6_timesync.c` already initialises 802.15.4 — TBR is a Kconfig flag away. Real value: HA's Improv-style commissioning works without a separate Thread border router box. +3. **HACS value-add** — config flow (UI setup wizard), Repairs API (structured error cards), re-authentication, diagnostics download, typed service actions (`set_privacy_mode`, `calibrate_zone`), i18n translations. **Bronze is the minimum bar; Gold (repairs + diagnostics + reconfiguration) is the target.** Start from `hacs.integration_blueprint` template. +4. **CSA certification** — ~$30-42k first year ($22.5k membership + $10-19k ATL lab fees). **Skippable for v1** by publishing as "Works with HA" instead. CSA re-evaluate at v0.9+ after HACS adoption data lands. +5. **Cog RAM budget** — 128 MB RAM / 15 % CPU on the Seed appliance (Pi 5 + Hailo-10 variant has more headroom). 10 KB INT8 semantic-primitive classifier fits without PSRAM. Long-lived supervised process with capability scopes `network.mqtt + network.matter + api.ruview_vitals`. +6. **ruvllm + RuVector latency** — `ruvllm-esp32` v0.3.3 confirms SONA self-optimising adaptation under 100 µs per query. 8→10 INT8 classifier ~10 KB quantised. Per-home threshold tuning via HA thumbs-up/thumbs-down feedback as LoRA-style gradient steps — closes the top user complaint (false positives) without cloud round-trips. +7. **HIPAA / FDA** — FDA January 2026 General Wellness guidance explicitly classifies HR / sleep / activity-anomaly alerts as **wellness devices** (outside FDA jurisdiction) when marketed without diagnostic claims. Frame fall detection as **"activity anomaly notification"** not "fall diagnosis". `--privacy-mode` audit-only tier (no MQTT state messages, only SHA-256 digests on-Seed) creates a technical PHI barrier. `OccupancySensor (0x0107)` device class keeps the product in the same regulatory category as a smart motion sensor. +8. **Competitor moat** — Aqara FP300 (Nov 2025): 5 entities, no person count, no vitals, no fall detection. TOMMY: zones only, no vitals, closed-source, paywalled. ESPectre: motion only. **RuView's differentiation** — HR/BR + 17-keypoint pose + 10 semantic primitives + witness chain + SONA adaptation — has no competitor equivalent. + +## 4.

Top priority was the sibling `wifi-densepose-engine` bug class — +unframed boundary-to-boundary concatenation of operator-influenceable strings +into a signed/hashed digest. + +- **Engine bug class ABSENT (good result, reported with byte evidence).** + `canonical_bytes` is `DOMAIN_TAG ‖ prev_hash[32] ‖ seq:u64-be ‖ ts:u64-be ‖ + kind_len:u32-be ‖ kind ‖ payload_len:u32-be ‖ payload`. The two + variable-length operator-influenceable fields (`kind`, `payload`) are + **length-prefixed**; the fixed-width fields are self-delimiting → the + encoding is injective (no two distinct event tuples share a preimage). The + Ed25519 signature signs the **identical** bytes the SHA-256 chain commits to. + No separate unframed concatenation exists; the manifest `binary_signature` + is signed at build time (Makefile) over a single fixed-length `binary_sha256` + hex value, not in-crate. + +- **CHM-WIT-01 (FIXED) — domain-separation tag added.** The engine fix + prescribed *domain-tag + length-prefix*; length-prefix was present, the + domain tag was not. Added a versioned, NUL-terminated + `WITNESS_DOMAIN_TAG = b"cog-ha-matter/witness-event/v1\x00"` prefix so the + witness message can never be replayed as a message for another Ed25519 + context that shares key infrastructure (notably the manifest signature). + **Witness bytes change by design** (prior on-disk hashes/signatures + invalidated, as with the engine fix); verified safe because no in-repo crate + consumes cog-ha-matter witness bytes programmatically (doc-mentions only). + +- **CHM-WIT-02 (HARDENED) — `verify_signature` now uses `verify_strict`.** For + an audit chain the signature is the attestation, so non-canonical encodings + and small-order keys are rejected (RFC 8032 strict), giving the "one + canonical signature per event" property.

Context + +### 1.1 What the pip package is today + +`wifi-densepose` v1.1.0 was published to PyPI on **2025-06-07** (two releases the same +day: 1.0.0 at 13:24 UTC, 1.1.0 at 17:02 UTC). Both wheels carry the tag +`py3-none-any` — no compiled extension, no platform-specific code. The package is a +**pure-Python server application** sourced entirely from `archive/v1/`. + +The package installs a 40-dependency stack including FastAPI, PyTorch, SQLAlchemy, +Redis, Celery, OpenCV, asyncpg, psycopg2, and Scapy (`archive/v1/setup.py:46–87`). +The declared entry points are: + +``` +wifi-densepose = src.cli:cli +wdp = src.cli:cli +``` + +(`archive/v1/setup.py:178–179`) + +The public API surface is centred on a FastAPI HTTP server, a SQLAlchemy/postgres +database layer, and a Redis/Celery task queue — none of which map to the current Rust +architecture. The `__init__.py` exports `app` (FastAPI), `CSIProcessor`, +`PhaseSanitizer`, `PoseEstimator`, `RouterInterface`, `ServiceOrchestrator`, +`HealthCheckService`, and `MetricsService` (`archive/v1/src/__init__.py:54–68`). + +### 1.2 Why this matters now + +ADR-115 (PR #778, merged 2026-05-23) shipped 21 Home Assistant entities, 10 semantic +primitives, mTLS, privacy mode, and a full witness bundle from the Rust crate +`wifi-densepose-sensing-server`. ADR-116 is packaging this as a Cognitum Seed cog. +Neither surface is reachable from `pip install wifi-densepose` — the pip package cannot +import a CsiFrame, decode an edge-vitals packet, call a DSP stage, verify a witness +bundle, or subscribe to the sensing server's MQTT or WebSocket endpoints. The ecosystem +split is now wide enough that the pip package actively misleads new users about what +the project does. + +Three concrete customer pain points: + +1. A Python user who `pip install wifi-densepose` expecting to consume live pose/vitals + data gets a FastAPI server that requires postgres + redis, not a library they can + script against. +2. Integrators writing HA automations or Node-RED flows in Python have no idiomatic + Python API for the v0.7 telemetry surface (ADR-115 entities, semantic primitives). +3. The ADR-028 witness chain (deterministic pipeline proof) is Python-based and + exercised via `archive/v1/data/proof/verify.py`, but it imports from the v1 stack — + it cannot witness the Rust pipeline that is now the production implementation. + +### 1.3 What this ADR is *not* + +- Not a removal of `archive/v1/` from the repository. The v1 codebase stays as a + research archive and its proof bundle stays in `archive/v1/data/proof/`. +- Not a port of the Rust crates to Python. The Rust workspace (`v2/`) is authoritative + and unmodified by this ADR. +- Not a replacement of the `wifi-densepose-sensing-server` Rust binary. The pip + package wraps or clients the binary; it does not reimplement it. +- Not an overlap with ADR-116 (Seed cog packaging). ADR-116 ships a Seed-installable + artifact; ADR-117 ships a Python developer library for scripting, automation, and + prototyping against the Rust stack. + +--- + +## 2.

Several integrators reading the ADR-115 release + notes asked about WiFi-6 dense-subcarrier capture; the answer is + BFLD, and we want the API stable before they build pipelines. +2. **Soul-signature dependency**. The soul-signature research spec + (`docs/research/soul/specification.md`) lists "Subcarrier Reflection + Profile" as one of seven biometric channels. At HE20/HE80 the + dense BFR subcarriers are the right input — exposing `BfldFrame` + now lets researchers prototype the channel without waiting on a + Rust ingestion crate. +3. **Cross-vendor portability**. CSI ingestion needs patched + firmware. BFR ingestion works on stock 802.11ac/ax hardware + (capture via `tcpdump`/Wireshark + a BFR dissector). Shipping the + Python data structures first gives the community a way to feed + RuView from gear we don't directly support. + +#### Implementation surface in P3 + +Lands as a new module `bindings/bfld.rs` (~150 lines, three +`#[pyclass]` types): + +- `BfldFrame` (frozen) — one compressed feedback matrix snapshot. + Constructors: `from_compressed_feedback(...)` and + `from_uncompressed_v(...)` (the 802.11n V-matrix form). + Properties: `timestamp_ms`, `sounding_index`, `sta_mac`, + `bandwidth_mhz`, `n_subcarriers`, `n_rows` (Nr), `n_cols` (Nc), + `feedback_matrix` (numpy ndarray complex64). +- `BfldReport` (frozen) — aggregator over a window of `BfldFrame`s. + Properties: `n_frames`, `timestamp_first`, `timestamp_last`, + `mean_amplitude_per_subcarrier`, `coherence_score`. The Python + side gives users a stable handle for "all BFR data in this 60-s + scan" without leaking the storage representation. +- `BfldKind` (`#[pyclass(eq, eq_int, hash, frozen)]`) — enum + enumerating the BFR variants we support: `CompressedHE20`, + `CompressedHE40`, `CompressedHE80`, `CompressedHE160`, + `UncompressedHT20`, `UncompressedHT40`. + +Stub Rust implementation lives in `python/src/bfld_stub.rs` until +the proper Rust crate exists; it's intentionally not in v2/crates/. +A new ADR-1xx will own the Rust ingestion crate when we commit to it. + +#### Open questions added + +- §9.11 — Should BFLD ingestion live in a new `wifi-densepose-bfld` + crate or in `wifi-densepose-signal` extended? +- §9.12 — Per-vendor BFR variant compatibility (Broadcom vs Intel vs + Qualcomm encode the compressed angles slightly differently) — how + much normalisation belongs in the Python binding vs. the future + Rust crate? + +### 5.7 Witness chain (re-rooted to the Rust pipeline) + +`wifi_densepose.witness.verify_bundle(path)` replaces the v1 proof verification with a +new chain that exercises the Rust pipeline via PyO3: + +```python +from wifi_densepose.witness import verify_bundle + +result = verify_bundle("dist/witness-bundle-ADR028-*/") +assert result.verdict == "PASS", result.detail +``` + +Internally it: +1. Loads the 1,000-frame reference JSON from the bundle. +2. Feeds each frame through `PyCsiProcessor` (PyO3 binding of the Rust `CsiProcessor`). +3. Hashes the output using the same SHA-256 scheme as `archive/v1/data/proof/verify.py`. +4.

Open questions + +1. **Stable ABI base version**: `abi3-py310` drops support for Python 3.9, which v1.1.0 + declared. Is Python 3.9 EOL-enough (EOL 2025-10-05) to drop cleanly? *Tentative: yes, + drop 3.9. Use abi3-py310.* + +2. **Package name for nn bindings**: if `wifi-densepose-nn` bindings require a 30 MB + libtorch wheel, should they live at `wifi-densepose-nn` (separate PyPI package) or + as an optional heavy extra of `wifi-densepose[nn]`? *Tentative: separate package to + avoid polluting the lean wheel.* + +3. **Witness hash continuity**: the Rust pipeline will produce a different SHA-256 than + the v1 Python pipeline for the same input frames. The new `expected_features_v2.sha256` + must be generated and committed before v2.0.0 ships. Who generates it, and how is + the generation process itself witnessed? *Tentative: generate in CI, commit hash to + `archive/v1/data/proof/`, include in ADR-028 matrix.* + +4. **`ruv-neural` crate**: `v2/crates/ruv-neural/` exists in the workspace. Is it a + candidate for early Python bindings (useful for training-loop scripting), or should + it wait for the nn/train tier? *Tentative: defer — it depends on training backends.* + +5. **Tokio runtime**: `wifi-densepose-sensing-server` is tokio-based, but the three + crates bound in P2–P3 (`core`, `vitals`, `signal`) are synchronous. Are there any + hidden tokio dependencies that would force a runtime into the extension module? + *Tentative: inspect each crate's Cargo.toml for tokio deps before P1 scaffold.* + +6. **`pyo3-stub-gen` vs manual stubs**: automated stub generation from PyO3 has rough + edges for generics and newtype patterns. Should we hand-write `.pyi` stubs for the + first release? *Tentative: use `pyo3-stub-gen` for scaffolding, hand-tune for public + API.* + +7. **`wifi_densepose` vs `wifi-densepose` namespace**: the pip package name uses a dash + (`wifi-densepose`) but Python imports use underscores (`wifi_densepose`). The v1 + package shipped under `src.*`, not `wifi_densepose.*`. Is there any tooling that + hardcodes the `src` namespace? *Tentative: the `src.*` namespace was specific to + `archive/v1/` and is cleanly dropped.* + +8. **cibuildwheel version**: the current stable is cibuildwheel v2.x. Does the + project's existing GitHub Actions config need updates for maturin builds vs + the current `cargo build` / `build.py` patterns? *Tentative: yes, add a separate + `pip-release.yml` workflow; do not modify existing Rust CI.* + +9. **RuVector bindings timeline**: the `wifi-densepose-ruvector` crate (`v2/crates/`) + depends on `ruvector-gnn = "2.0.5"`. Does ruvector-gnn ship as a pre-built static + lib or require linking at build time? This directly affects the P6+ wheel size. + *Tentative: investigate ruvector-gnn link strategy before committing to a timeline.* + +10. **`wifi_densepose.client.ha` conflict with ADR-115/116**: the `ha.py` helper module + should not duplicate the ADR-115 MQTT discovery logic in Python. Should it be read-only + (parse HA discovery JSON → Python dataclasses) or also write (publish discovery JSON)? + *Tentative: read-only for v2.0. Write path deferred to the HACS integration follow-on + (ADR-115 §6.A).* + +11. **BFLD Rust crate ownership** (added 2026-05-24): the P3.5 BFLD bindings ship with a + stub Rust impl in `python/src/bfld_stub.rs`. The proper Rust crate (Nexmon BFR pcap + parser + `mac80211` debugfs ingestor) will land later. Should it be a new + `wifi-densepose-bfld` workspace member, or should it extend `wifi-densepose-signal`? + *Tentative: new dedicated crate. Reasons: (a) the BFR parser is significant code + (Wireshark's dissector is ~2k lines) and bloats `-signal`; (b) BFLD ingestion is + optional — many deployments will only use CSI; gating behind a separate crate keeps + the default `-signal` lean. Decide before committing to the crate name in any + `pyproject.toml` extras.* + +12. **BFLD per-vendor compressed-angle variants** (added 2026-05-24): 802.11 standardizes + the compressed beamforming feedback format but vendors (Broadcom, Intel, Qualcomm, + MediaTek) differ in psi/phi quantization step + ordering of consecutive matrix + entries. How much normalisation belongs in the Python `BfldFrame.from_compressed_feedback` + binding vs. the future Rust crate? *Tentative: Python binding is dumb (numpy ndarray + in, numpy ndarray out — no decoding); the future Rust crate owns per-vendor + normalisation, exposed via a `Vendor` enum on the binding constructor. Confirm via + a per-vendor test fixture before P3.5 ships.* + +--- + +## 12.

Context + +### 1.1 The plaintext BFI problem + +IEEE 802.11ac and 802.11ax beamforming feedback (BFI) is exchanged between client stations (STA) and access points (AP) in **unencrypted management-plane frames**. The STA compresses the channel response into a Givens-rotation angle matrix (Φ/ψ) and transmits it as a VHT/HE Compressed Beamforming Report (CBFR). Any device in WiFi monitor mode within range can passively sniff these frames without joining the network. + +Two independent 2024–2025 research results establish the severity of this exposure: + +1. **BFId** (KIT, ACM CCS 2025) — re-identifies 197 individuals from BFI alone with >90% accuracy from 5 s of capture. https://publikationen.bibliothek.kit.edu/1000185756 +2. **LeakyBeam** (NDSS 2025) — detects occupancy through walls at 20 m with 82.7% TPR / 96.7% TNR using only plaintext BFI. https://www.ndss-symposium.org/wp-content/uploads/2025-5-paper.pdf + +Capture tooling is freely available: **Wi-BFI** (pip-installable), **PicoScenes**, **Nexmon BFI patches** for BCM43455c0 (Raspberry Pi 5 / 4 / 3B+). + +### 1.2 Gap in the existing RuView pipeline + +The wifi-densepose / RuView pipeline processes CSI via the rvCSI runtime (ADR-095/096) and emits presence, pose, vitals, and zone-activity events. **No layer in the existing pipeline measures whether the data it is processing is capable of identifying individuals.** All CSI is treated as equivalent from a privacy standpoint regardless of operating regime. + +This gap becomes a compliance and liability issue at deployment scale. An operator placing RuView in a care home, hotel, shared office, or rental property has no instrument to verify that the system is operating anonymously. + +### 1.3 BFI as a sensing signal + +BFI is not only a threat vector — its compressed angle matrices carry multipath geometry useful for presence and motion detection, particularly in single-AP deployments where MIMO CSI is unavailable. BFLD treats BFI as an **optional input alongside CSI**, not a replacement. + +### 1.4 Relationship to the Soul Signature research + +The Soul Signature research (`docs/research/soul/`) defines a 7-channel multi-modal biometric for **consent-based** passive re-identification of enrolled individuals. Where Soul Signature *intentionally produces* identity (with a 60-second enrollment protocol), BFLD *measures and gates* identity leakage from the same sensing substrate. The two systems are complementary by design: + +| Concern | Soul Signature | BFLD | +|---------|----------------|------| +| Intent | Create a biometric for enrolled persons | Measure and gate identity leakage | +| Consent model | Explicit enrollment, GDPR/HIPAA modes | Default-deny, all unenrolled persons | +| Operating class | Must run at `privacy_class = 1` (derived) | Defaults to class 2 (anonymous) | +| Shared assets | AETHER encoder (ADR-024), WitnessChain (ADR-110/028), RVF container, `cross_room.rs` (ADR-030) | Same | +| ID space | Long-lived opaque `person_id` per enrolled subject | Rotating `rf_signature_hash` per day per unenrolled person | + +BFLD becomes Soul Signature's enforcement layer: the `identity_risk_score` gates whether a zone is leaky enough to enroll, the witness bundle is the regulator-facing audit artifact, and the structural privacy invariants (I1/I2/I3) ensure unenrolled bystanders stay anonymous even in zones where Soul Signature is actively matching enrolled persons. See ADR-120 §2.7 and ADR-121 §2.7 for the integration points. + +### 1.5 What this ADR is *not* + +- Not a removal of the CSI pipeline.

BFLD requires the latter because the `BfldFrame` payload mixes sensing data (publishable) and identity-derived data (non-publishable) in the same struct. + +The BFId paper (KIT, ACM CCS 2025) demonstrates that even a few minutes of BFI capture across the same site is sufficient to build a persistent biometric. The mitigation must be **structural**, not policy-dependent. + +--- + +## 2. Decision + +### 2.1 The four privacy classes + +A single `privacy_class: u8` byte in the `BfldFrame` header (ADR-119 §2.1) selects one of four classes. The crate enforces field availability statically through marker types. + +| Class | Name | Use case | Available fields | +|-------|------|----------|------------------| +| **0** | `raw` | Local-only research, never networked | All fields, full-precision BFI matrix, identity embedding | +| **1** | `derived` | Operator-acknowledged research over LAN | Downsampled angle matrix, full features, identity_risk_score, identity_embedding | +| **2** | `anonymous` (**default**) | Production deployment | Aggregate sensing only: presence, motion, person_count, zone_id, confidence | +| **3** | `restricted` | Care-home / regulated deployment | Class 2 minus `identity_risk_score` and `rf_signature_hash` | + +Default for new RuView nodes is class **2**. Operators must explicitly opt-down to class 1 via the existing `--research-mode` flag (ADR-115 §7); class 0 is reserved for `cargo test` and is unreachable from `wifi-densepose-sensing-server`. + +### 2.2 Enforcement via marker types + +```rust +pub trait Sink {} + +pub trait LocalSink: Sink {} // Allowed: classes 0,1,2,3 +pub trait NetworkSink: Sink {} // Allowed: classes 1,2,3 (NOT class 0) +pub trait MatterSink: NetworkSink {} // Allowed: class 2,3 + cluster-filter (ADR-122) + +impl Emitter { + pub fn publish(&self, sink: &S, frame: BfldFrame) + -> Result<(), BfldError> + { + if frame.header.privacy_class == 0 { + return Err(BfldError::PrivacyViolation { + reason: "class 0 to NetworkSink", + }); + } + // ... serialize and write + } +} +``` + +The compiler refuses to call `publish` on a sink that doesn't impl `NetworkSink` with a class-0 frame because the runtime check is paired with a sink-marker check. Cross-sink frame routing requires an explicit class transition (see §2.4). + +### 2.3 BLAKE3 keyed hash rotation for `rf_signature_hash` + +The signature hash is computed as: + +```rust +pub fn rf_signature_hash( + site_salt: &[u8; 32], // generated on first boot, persisted in TPM/KMS + day_epoch: u32, // floor(unix_time_utc / 86400) + features: &IdentityFeatures, +) -> Hash { + let mut hasher = blake3::Hasher::new_keyed(site_salt); + hasher.update(&day_epoch.to_le_bytes()); + hasher.update(&features.canonical_bytes()); + hasher.finalize() +} +``` + +**Structural cross-site isolation**: because `site_salt` is a 256-bit random secret unique to each node and never transmitted, two sites observing the same physical person produce uncorrelated hashes. There is no key the operator (or an attacker who compromises one node) can use to bridge sites. This is stronger than a policy-based "do not share" rule because the bridge **cannot be computed**. + +**Daily rotation**: `day_epoch` flipping at UTC midnight forces the hash of the same person to change once per day. Multi-day correlation requires re-acquiring the biometric, which the rotation actively breaks. + +### 2.4 Class-transition transformer + +The only way a high-class frame becomes a lower-class frame is through `PrivacyGate::demote(frame, target_class)`. This function: + +1. Asserts the target class is strictly higher number than (or equal to) the input class. +2. Zeroes the disallowed fields with `subtle::Zeroize`. +3. Re-computes `payload_crc32`. +4. Returns the new frame. + +There is no `promote` operation — a class-2 frame cannot be turned back into a class-1 frame, because the dropped fields were not retained anywhere reachable from the gate. + +### 2.5 `identity_embedding` lifecycle + +The embedding (output of the AETHER encoder, ADR-024) is held in a `subtle::Zeroizing<[f32; 128]>` ring buffer of 64 entries (≈30 KB). Entries are: + +1. Written by the encoder on each capture window. +2. Consumed by `identity_risk_score` computation (ADR-121). +3. **Never** written to disk, MQTT, or any other I/O sink — there is no `Serialize` impl on the type. +4. Overwritten by the ring (FIFO). + +A compile-time `#[forbid(serde::Serialize)]` lint on `IdentityEmbedding` ensures a future PR cannot accidentally add a `Serialize` derive. + +### 2.6 Default-deny field classification + +Every new field added to `BfldFrame` or `BfldEvent` must be tagged with `#[must_classify]` (a custom attribute macro). The macro fails compilation if the field is not listed in the per-class allow-list table. This forces future contributors to make an explicit privacy decision on every new field. + +### 2.7 Dual-ID-space contract for Soul Signature deployments + +Soul Signature (`docs/research/soul/`) is a consent-based biometric system that *intentionally* produces long-lived per-person identity. It cannot operate at the default class 2 — the identity_embedding it needs is structurally absent there. The contract: + +| Deployment mode | `privacy_class` | ID space for unenrolled bystanders | ID space for enrolled persons | +|---|---|---|---| +| Default BFLD-only | 2 (anonymous) | Daily-rotated `rf_signature_hash` | n/a — no enrollment | +| Soul Signature opt-in | **1 (derived)** | Daily-rotated `rf_signature_hash` (unchanged) | Long-lived opaque `person_id` from Soul Signature graph | +| Restricted / care-home | 3 (restricted) | Suppressed | n/a — Soul Signature **disabled** at class 3 | + +Two ID spaces coexist with **no collision**: the rotating hash is the privacy-preserving identifier for everyone *not* on the consent roster; the stable `person_id` is reserved for enrolled subjects under their own GDPR/HIPAA mode. Soul Signature's `match_against_enrolled()` function consumes only the in-RAM `identity_embedding` (I2 still holds) and emits a `person_id` plus a calibrated similarity score; it never writes the embedding to disk or the wire. The class-1 requirement is enforced statically: the Soul Signature match API takes a `&IdentityEmbedding` parameter, which is only constructible when the BFLD crate is compiled with `--features soul-signature` against a class-1 frame. + +--- + +## 3. Consequences + +### Positive + +- Cross-site identity correlation is **computationally impossible**, not merely "prohibited by policy". This is the strongest form of privacy guarantee available without a TEE. +- Default-deny via `#[must_classify]` prevents the common pattern of "a new field shipped, then six months later we noticed it was identity-leaky". +- `identity_embedding` cannot be serialized by accident — the type system carries the constraint. +- The class transition transformer makes the data lifecycle explicit and auditable. + +### Negative + +- `site_salt` storage requires either a TPM (ADR-095/096 rvCSI platform feature gap) or a secrets file with strict mode. Loss of `site_salt` makes historical witness comparisons impossible — by design, but a documentation hazard. +- `#[must_classify]` is a custom proc-macro; another moving part in the build. +- Operators wanting multi-day analytics must work in aggregates only, not on per-individual signatures. + +### Neutral + +- Class 0 is `cargo test`-only. Some CI runners may need an explicit feature flag to compile class-0 paths. + +--- + +## 4. Alternatives Considered + +### Alt 1: Single boolean `privacy_mode` flag (status quo from ADR-115) + +Rejected: insufficient granularity. The frame mixes publishable sensing with non-publishable identity, so the gate must operate at field-level, not event-level. + +### Alt 2: SHA-256 instead of BLAKE3 + +Rejected: BLAKE3 keyed-hash mode is ~5× faster on the ESP32-S3 / Cortex-M cores and the security margin is equivalent for this use case. SHA-256 has no keyed-hash mode (HMAC-SHA256 is the alternative; works but is slower). + +### Alt 3: Hash rotation on the hour, not the day + +Rejected: hourly rotation breaks legitimate "person was here in the morning, came back in the afternoon" use-cases that operators may want. Day boundary is the compromise. + +### Alt 4: Per-event nonces instead of daily epoch + +Rejected: per-event nonces would force the consumer to track which events came from the same person within a session, which leaks identity information by structure.

BFLD's risk scoring borrows the gate-pattern but with identity leakage as the trigger condition. + +--- + +## 2. Decision + +### 2.1 Nine features (from BFLD spec §5) + +The features are computed over a sliding window of `W = 32` BFI frames (≈3 s at 10 Hz): + +| Feature | Definition | Source | +|---------|------------|--------| +| `mean_angle_delta` | mean( ‖ Φ_t − Φ_{t-1} ‖ over subcarriers ) | extractor | +| `subcarrier_variance` | var( ‖ Φ ‖ over subcarrier axis ) | extractor | +| `temporal_entropy` | Shannon entropy of angle-bin histogram over W | extractor | +| `doppler_proxy` | FFT peak magnitude of mean-angle time series | features.rs | +| `path_stability` | 1 − ‖ Φ_t − median(Φ_{t-W..t}) ‖ / scale | features.rs | +| `cross_antenna_correlation` | mean Pearson correlation across n_tx × n_rx pairs | features.rs | +| `burst_motion_score` | high-pass-filtered angular velocity, soft-thresholded | features.rs | +| `stationarity_score` | 1 − rolling KL divergence over W/2 vs W | features.rs | +| `identity_separability_score` | top-1 cosine to nearest AETHER cluster centroid | identity_risk.rs | + +The first eight are sensing features (also used by the presence/motion pipeline). Only the ninth depends on the AETHER embedding and therefore on `identity_class >= 1`. + +### 2.2 Identity risk formula + +```rust +pub fn identity_risk_score( + sep: f32, // identity_separability_score, [0, 1] + stab: f32, // temporal_stability, [0, 1] = ema(path_stability, alpha=0.1) + consist: f32,// cross_perspective_consistency, [0, 1] = multistatic.rs + conf: f32, // sample_confidence, [0, 1] = f(SNR, n_subcarriers, n_rx) +) -> f32 { + // Clamp inputs, then multiplicative combination — any factor near 0 dominates. + let s = sep.clamp(0.0, 1.0); + let t = stab.clamp(0.0, 1.0); + let p = consist.clamp(0.0, 1.0); + let c = conf.clamp(0.0, 1.0); + (s * t * p * c).clamp(0.0, 1.0) +} +``` + +Multiplicative combination is chosen so that **any** weak factor (e.g., very low SNR ⇒ low `conf`) collapses the score toward 0. This matches the privacy intent: when the system is uncertain, the score should be low and the operator should not be alarmed. + +### 2.3 Calibration target + +The score is calibrated against re-ID success rate on a held-out test split of the KIT BFId dataset. A piecewise-linear isotonic regression maps raw scores into a calibrated `[0, 1]` band where `score ≥ 0.8` corresponds to `>80%` re-ID accuracy on a 5-second window in the calibration dataset. + +Calibration parameters live in `v2/crates/wifi-densepose-bfld/data/risk_calibration.toml` and are versioned independently of the code. A regression update is a content-only PR. + +### 2.4 Coherence gate + +The coherence gate (per ADR-029 `coherence_gate.rs` pattern) consumes the risk score and emits one of four actions: + +```rust +pub enum GateAction { + Accept, // score < 0.5, publish normally + PredictOnly, // 0.5 <= score < 0.7, publish but flag confidence + Reject, // 0.7 <= score < 0.9, drop the event + Recalibrate, // score >= 0.9, drop AND rotate site_salt +} +``` + +The `Recalibrate` action triggers a forced site-salt rotation — an aggressive response to a sustained high-risk regime. It costs the operator continuity of long-term aggregate analytics but is the right answer to an attacker-grade sniffer arriving in range. + +### 2.5 Hysteresis + +To prevent oscillation around the gate thresholds, the gate uses ±0.05 hysteresis and a 5-second debounce. A score must cross the boundary by the hysteresis margin and persist for the debounce window before the gate action changes. + +### 2.6 Soul Signature interaction — Recalibrate exemption and enrollment-quality gate + +Soul Signature (`docs/research/soul/`) intentionally exists in a high-separability regime — the whole point of its 60-second enrollment protocol is to push `identity_separability_score` toward 1.0. The default coherence gate (§2.4) would therefore fire `Recalibrate` constantly inside Soul Signature zones, rotating `site_salt` every few seconds and breaking enrollment. + +Two integrations resolve this: + +1. **Recalibrate exemption.** When the gate is about to fire `Recalibrate`, it consults a `SoulMatchOracle` (provided by the Soul Signature crate when compiled with `--features soul-signature`). If the oracle reports that the current high-separability cluster matches an enrolled `person_id` above the Soul Signature acceptance threshold, the gate downgrades to `PredictOnly` instead. The high score is the *intended* outcome of a successful match, not an attack indicator. Without the `soul-signature` feature, the oracle is a no-op stub returning `MatchOutcome::NotEnrolled`, so the gate behaves exactly per §2.4. + +2. **Enrollment-quality gate.** Soul Signature's enrollment protocol (`scanning-process.md` §3) requires that the sensing zone meet a minimum identity-leakage regime — too low, and the resulting signature is unreliable. The BFLD `identity_risk_score` is exactly the right signal. Soul Signature gates enrollment on `score >= ENROLL_MIN` (default `0.65`) sustained over the 60-second window. If the score drops below threshold mid-enrollment, the protocol aborts and the operator is prompted to re-attempt in better RF conditions. + +The exemption is asymmetric: it suppresses `Recalibrate` only for known-enrolled matches. Unknown high-separability clusters (a real attacker-grade sniffer, or an unenrolled person whose identity is unexpectedly leaky) still trigger `Recalibrate` as designed. + +### 2.7 Compute budget + +| Stage | Target latency | Implementation | +|-------|----------------|----------------| +| Feature extraction (8 features) | < 3 ms per window | ndarray + nalgebra; vectorized over subcarriers | +| Separability (cosine to centroids) | < 5 ms per window | RuVector RaBitQ index (ADR-085) over ≤ 1k centroids | +| Risk score | < 0.1 ms | scalar multiplicative | +| Gate decision + hysteresis | < 0.1 ms | scalar | + +Total p95 ≤ 10 ms per window on a Pi 5 core (8 ms target). Headroom on cognitum-v0 (Pi 5 + Hailo) is ample; ESP32-S3 hosts only the extraction stage (features computed; risk score is host-side per ADR-123). The `SoulMatchOracle` lookup (§2.6) adds < 1 ms when the `soul-signature` feature is enabled (RaBitQ index over enrolled centroids). + +--- + +## 3. Consequences + +### Positive + +- The risk score becomes a first-class diagnostic surface for operators and a structural input to the privacy gate — both consumers from a single computation. +- Multiplicative combination is conservative under uncertainty; the system is biased toward "report low risk when unsure", which is the right default. +- Calibration is a content-only update — no recompile needed when the calibration file changes. +- The recalibration gate action gives the system a self-healing response to a sniffer arrival without operator intervention. + +### Negative + +- Calibration requires the KIT BFId dataset; without it the score is uncalibrated and serves only as an internal trigger, not a publishable signal. +- Multiplicative scoring can be dominated by `sample_confidence`, which is sensitive to channel conditions. A persistent low-SNR environment will keep the published score near 0 even when the underlying separability is high — an under-reporting failure mode that the documentation must call out. +- The recalibrate action breaks historical hash continuity by design; an operator who wants long-term aggregates needs to know they will see a discontinuity on recalibrate events. + +### Neutral + +- The nine features overlap with the existing CSI pipeline. BFLD computes them on BFI; the CSI pipeline computes them on CSI. Both can be fused via `cross_perspective_consistency`. + +--- + +## 4. Alternatives Considered + +### Alt 1: Additive scoring (`(s + t + p + c) / 4`) + +Rejected: a sample with high separability but very low confidence would still produce a moderate score, which over-reports risk in degraded RF conditions. + +### Alt 2: Maximum scoring (`max(s, t, p, c)`) + +Rejected: over-reports risk because any single high factor pins the output, even if the others contradict it. + +### Alt 3: Learned scoring (a small MLP) + +Rejected for this ADR: introduces an opaque model whose output cannot be audited from first principles. The multiplicative formula is simple, conservative, and directly explainable to operators. A learned model is a future option once enough calibration data is in hand. + +### Alt 4: Per-feature thresholds instead of a continuous score + +Rejected: continuous score is needed for the HA gauge entity and for downstream calibration. Per-feature thresholds would force operators to interpret nine separate binaries. + +--- + +## 5. Acceptance Criteria + +- [ ] **AC1**: All nine features are computed in `< 8 ms` p95 per window on a Pi 5 core. +- [ ] **AC2**: `identity_risk_score` is monotonic non-decreasing in any single input when the other three are held constant. +- [ ] **AC3**: Calibration regression on the KIT BFId test split: `score ≥ 0.8` corresponds to ≥ 80% re-ID accuracy ± 5%. +- [ ] **AC4**: The coherence gate emits `Recalibrate` if score is ≥ 0.9 for ≥ 5 seconds. +- [ ] **AC5**: Hysteresis prevents action oscillation across ± 0.05 of a threshold within a 5-second window. +- [ ] **AC6**: At `privacy_class = 3`, the risk score is computed but not published to MQTT (kept local for the gate only). +- [ ] **AC7**: A reproducible 1,000-frame synthetic fixture produces a deterministic score sequence (bit-identical across runs). + +--- + +## 6.

It is the natural BFLD capture host. + +### 1.3 What we need from each hardware tier + +| Tier | Role | BFI capture | CSI capture | Notes | +|------|------|-------------|-------------|-------| +| ESP32-S3 / C6 | Sensing leaf | **no** | yes | Continues providing CSI to the existing pipeline | +| Pi 5 / Nexmon | BFLD host | **yes** | yes (via Nexmon) | Primary BFLD capture | +| ruvultra (RTX 5080 + AX210) | Training / dev | yes (via AX210 monitor mode) | yes | Dev capture; not production | +| cognitum-v0 (Pi 5) | Appliance | **yes** (production) | yes | Production BFLD host | + +--- + +## 2. Decision + +### 2.1 Production capture path: Pi 5 / Nexmon + +The BFLD production capture path is implemented as a new module in the vendored rvCSI submodule: + +``` +vendor/rvcsi/crates/rvcsi-adapter-nexmon/ +└── src/ + ├── lib.rs + ├── csi.rs # existing CSI capture + └── bfi.rs # NEW — CBFR capture, exports BfiCapture +``` + +The new `bfi.rs` parses CBFR frames (VHT or HE) from the Nexmon-patched firmware's userspace stream, extracts Φ/ψ angle matrices, and emits a `BfiCapture` struct that feeds the BFLD crate's extractor (ADR-118 §2.1, ADR-119). + +The patch lives in the rvcsi submodule (`github.com/ruvnet/rvcsi`) and is shipped as `rvcsi-adapter-nexmon ^0.3.5` to crates.io. The wifi-densepose workspace consumes the published crate (or the submodule path during development). + +### 2.2 BFLD crate adapter trait + +`wifi-densepose-bfld` defines a `BfiCaptureAdapter` trait: + +```rust +pub trait BfiCaptureAdapter: Send + 'static { + type Error: std::error::Error + Send + Sync + 'static; + fn capture(&mut self) -> Result, Self::Error>; + fn capabilities(&self) -> AdapterCapabilities; +} + +pub struct AdapterCapabilities { + pub supports_he: bool, // 802.11ax (Wi-Fi 6) + pub supports_160mhz: bool, + pub max_n_rx: u8, + pub host_kind: HostKind, // Pi5Nexmon | Ax210Linux | EspS3Local | Mock +} +``` + +Three impls ship initially: + +- `NexmonBfiAdapter` — Pi 5 / Nexmon (production) +- `Ax210BfiAdapter` — Linux + AX210 in monitor mode (dev / training, ruvultra) +- `MockBfiAdapter` — replay fixture for tests and CI + +A future fourth impl (`EspS3LocalAdapter`) is reserved for the day Espressif exposes promiscuous CBFR — it captures only the S3's own AP-link BFI for local self-reporting. + +### 2.3 Capture-side privacy boundary + +Per ADR-120 I1, raw BFI never leaves the capturing host. The adapter must therefore live on **the same physical box** as the BFLD crate's extractor and privacy gate. The architecture pattern: + +``` +[ Pi 5 / cognitum-v0 ] +├── nexmon firmware (kernel) +├── rvcsi-adapter-nexmon (userspace, captures BFI) +├── wifi-densepose-bfld (extracts, scores, gates) +│ └── privacy_gate → class-2/3 frames only +└── wifi-densepose-sensing-server (publishes MQTT + Matter) +``` + +A network-mode adapter that streams raw BFI from a remote capture host is **explicitly forbidden**. The adapter trait does not include any "remote URL" parameter. + +### 2.4 Channel / bandwidth coverage + +The Nexmon adapter is configured by the existing `rvcsi-adapter-nexmon` channel-hopping schedule (ADR-095 §3.2). For BFLD it adds: + +- Filter for VHT CBFR (action frame, category 21, action 0) and HE CBFR (category 30, action 0). +- Per-channel BFI session-tracking — the same beamformer/beamformee pair across a channel hop is reconciled by AP MAC + STA MAC. + +### 2.5 ESP32-S3 local self-reporting (deferred) + +For deployments without a Pi 5 / cognitum-v0 nearby, a degraded BFLD mode runs on the ESP32-S3 itself: + +- Captures only its own AP-link CBFR (self-addressed). +- Computes features over the limited window. +- Reports a coarsened `presence` + `motion` only — no `identity_risk_score` (insufficient sample diversity). +- Emits `BfldFrame` at `privacy_class = 2` with a `flags.bit3 = self_only` marker. + +This path is implemented in firmware as part of P2 / P3 of the ADR-118 rollout, after the Pi 5 path is stable. Effort is small (firmware path reuses the existing CSI capture loop) but the value is also low until ESP32 firmware exposes promiscuous CBFR — which is a Espressif-IDF roadmap item, not under project control. + +### 2.6 Dev path: ruvultra / AX210 + +For local dev iteration on the Windows / ruvultra box, the AX210 adapter provides a workable capture path on Linux (ruvultra is Ubuntu 6.17 per CLAUDE.local.md). The AX210 supports 802.11ax + monitor mode with the `iwlwifi` driver patches that have landed upstream. This path is for training-data collection and dev testing, not production. + +--- + +## 3. Consequences + +### Positive + +- BFLD ships as a production-ready surface on cognitum-v0 day one — no new hardware procurement. +- The adapter-trait design lets new capture paths (AX211, MediaTek Filogic, etc.) slot in without changes to the BFLD crate. +- The capture-side privacy boundary is structural: there is no remote-capture code path, so a future PR cannot accidentally introduce one. +- ruvultra's AX210 path unblocks training and dev iteration on Linux without depending on the Pi 5 fleet. + +### Negative + +- BFLD's full pipeline depends on cognitum-v0 (or another Pi 5 / Nexmon host) being present in the deployment. Operators without a Pi 5 get only the degraded ESP32-S3 self-reporting path (limited utility). +- Nexmon is a third-party kernel module; tracking upstream patches is ongoing maintenance. +- The CBFR frame format differs between VHT (802.11ac) and HE (802.11ax); the parser must support both, and any 802.11be (Wi-Fi 7) deployment will require an additional parser path. + +### Neutral + +- ruvultra dev path uses AX210; the AX210 is not the production NIC, so dev/prod parity is via the fixture replay + the Nexmon adapter on cognitum-v0. + +--- + +## 4. Alternatives Considered + +### Alt 1: Centralized capture host streams raw BFI to RuView nodes + +Rejected: violates ADR-120 I1 (raw never leaves the capture host). The capture host **is** the BFLD node; there is no separation. + +### Alt 2: Wait for Espressif promiscuous CBFR support + +Rejected: indefinite timeline outside project control. The Pi 5 / Nexmon path is shippable today. + +### Alt 3: Custom Pi 5 firmware fork instead of Nexmon + +Rejected: forking BCM firmware is a huge maintenance burden and Nexmon already does what we need. + +### Alt 4: Only ship the ESP32-S3 self-reporting path + +Rejected: insufficient sample diversity for `identity_risk_score`. The whole point of BFLD is to measure identity leakage; a self-only path cannot do that meaningfully. + +--- + +## 5. Acceptance Criteria + +- [ ] **AC1**: `NexmonBfiAdapter` captures ≥ 100 valid CBFR frames per minute from a 2-AP-3-STA test bench on a Pi 5 (cognitum-v0). +- [ ] **AC2**: VHT (802.11ac) and HE (802.11ax) CBFR frames are both parsed; mixed-PHY captures produce correctly-typed `BfiCapture` outputs. +- [ ] **AC3**: 20/40/80/160 MHz channel widths are all supported (one fixture each in `tests/`). +- [ ] **AC4**: `BfiCaptureAdapter` trait has no method accepting a remote URL or socket address. +- [ ] **AC5**: ESP32-S3 self-only adapter compiles `#[no_std]` and produces a `BfldFrame` with `flags.bit3 = self_only` set, no `identity_risk_score` field. +- [ ] **AC6**: AX210 adapter on ruvultra captures CBFR for at least one fixture-generating dev session. +- [ ] **AC7**: Capture loop sustains 10 Hz BFI frame rate on cognitum-v0 without dropping frames over a 10-minute soak test. + +--- + +## 6.

Context + +### 1.1 The access-layer gap + +The RuView / wifi-densepose Rust stack exposes sensing data through three surfaces: a Tokio/Axum HTTP REST API and WebSocket at `wifi-densepose-sensing-server` (ADR-055); an MQTT namespace under `ruview//*` (ADR-115); and an rvCSI edge runtime (ADR-095/096). None of these surfaces speaks Model Context Protocol (MCP). + +MCP is the dominant inter-process contract through which AI assistants (Claude, GPT, Codex) invoke external capabilities in 2026. Without an MCP bridge, RuView's sensing primitives are invisible to AI-driven automation workflows. An agent cannot ask "who is in the room?" or "subscribe me to fall alerts" without bespoke HTTP integration code in every consuming agent. + +Two concrete user stories that SENSE-BRIDGE resolves: + +1. A developer has a Claude Code session and wants to call `vitals.get_heart_rate` from a prompt — today this requires them to write an HTTP fetch, parse JSON, and handle WebSocket reconnect logic; with SENSE-BRIDGE they install `@ruvnet/rvagent` and the tool is available immediately via `claude mcp add rvagent`. +2. A ruflo-orchestrated multi-agent swarm needs real-world presence data to gate a workflow: SENSE-BRIDGE gives the swarm an MCP tool call with the same `mcp__claude-flow__*` signature pattern already used for all other ruflo tools (CLAUDE.md §Ruflo Automation Primitives). + +### 1.2 What rvagent is today + +Research of the ruvnet npm registry profile and the ruflo GitHub repository (issue #1689) establishes that **rvagent is not yet a published standalone npm package** as of 2026-05-24. The name "rvagent" appears in the ruflo project exclusively as a WASM artifact (`rvagent_wasm_bg.wasm`, 588 KB) bundled with the RuFlo Web UI (PR #1687). That artifact exports 13 WASM functions including `callMcp`, `executeTool`, `listTools`, `listGalleryTemplates`, `searchGalleryTemplates`, and `loadGalleryTemplate`. It is an in-browser MCP client runner, not a RuView-specific MCP server. + +There is no `rvagent` package on the npm registry as of this writing. The npm name is therefore available (Q1 in §8). The package name to register is `@ruvnet/rvagent` (scoped form, reduces name-squatting risk) or `rvagent` (unscoped form, simpler `npx` invocation). This ADR proposes `@ruvnet/rvagent`. + +The WASM `callMcp` / `executeTool` surface of the existing ruflo rvagent is the functional model for what the new npm package should expose in TypeScript — but the new package is a **server**, not a client, and its tools are RuView-domain-specific rather than general ruflo-gallery tools. + +### 1.3 MCP transport landscape as of 2026-05-24 + +The MCP specification shipped version `2025-03-26` (Streamable HTTP) and `2025-06-18` (current stable) replacing the legacy `2024-11-05` HTTP+SSE transport. Key facts relevant to this ADR: + +- **stdio** remains the recommended local transport. Clients launch the MCP server as a subprocess; the server reads JSON-RPC from stdin and writes to stdout. This is the path `claude mcp add -- npx @ruvnet/rvagent stdio` uses (CLAUDE.md §Quick Setup mirrors this pattern for the claude-flow MCP server). +- **Streamable HTTP** (colloquially "SSE" in earlier documentation) replaces the deprecated pure-SSE transport. A single HTTP endpoint at e.g. `POST /mcp` accepts JSON-RPC requests and may respond with `Content-Type: text/event-stream` for streaming, or `application/json` for single-turn responses. The server must validate `Origin` headers and bind to `127.0.0.1` by default (MCP spec security requirement). +- The `@modelcontextprotocol/sdk` npm package (latest stable at time of writing) ships `Server`, `StdioServerTransport`, and `StreamableHTTPServerTransport`. A single `Server` instance can be connected to both transports simultaneously by calling `server.connect(transport)` for each. +- The legacy `SSEServerTransport` from protocol version `2024-11-05` is deprecated but still ship-able for backwards compatibility with older Claude desktop clients. SENSE-BRIDGE will support it behind an `--legacy-sse` flag for a single release cycle, then remove it. + +### 1.4 ruvector npm surface + +The `ruvector` npm package (version 0.2.x, latest 0.2.25 as of ~2026-05-01) is a napi-rs WASM/Node.js binding of the RuVector Rust crate. It provides: + +- HNSW in-memory vector index (sub-0.5 ms query latency, 50 K+ QPS single-threaded) +- 50+ attention mechanisms from the RuVector Rust crate +- FlashAttention-3 SIMD path +- Graph Neural Network support via `@ruvector/gnn` +- Full TypeScript types; ships both ESM and CJS + +The `ruvector` package is already a dependency in the existing Rust workspace's napi-rs node bindings (`ruvector-node` crate, version 0.1.29 on crates.io). The npm package and the Rust crate are developed in the same repository (`github.com/ruvnet/ruvector`). SENSE-BRIDGE can depend on `ruvector` directly without needing to add new Rust FFI — the vector ops needed (HNSW index of pose keypoints, embedding storage for AETHER person re-ID) are already exposed in the npm package's public surface. + +### 1.5 ruflo integration context + +The project's `CLAUDE.md` documents the 3-tier model routing (ADR-026) and the `mcp__claude-flow__*` tool namespace. ruflo exposes 314 native MCP tools. SENSE-BRIDGE adds a new domain namespace `mcp__rvagent__*` that represents RuView sensing capabilities, parallel to but separate from the ruflo tools. The boundary is: +- **ruflo**: agent orchestration, memory, swarm coordination, hooks, task management +- **rvagent / SENSE-BRIDGE**: RuView-specific sensing — presence, vitals, pose, BFLD, semantic primitives + +ruflo can call rvagent tools via the standard MCP tool-call mechanism; rvagent does not depend on ruflo at runtime (but may optionally use ruflo memory namespaces for persistence). + +--- + +## 2. Decision + +Ship `@ruvnet/rvagent` as a standalone npm TypeScript library that: + +1. Exposes a **dual-transport MCP server** (stdio + Streamable HTTP) wrapping RuView sensing primitives. +2. Uses `ruvector` (npm) as the vector storage layer for pose embeddings and AETHER-class semantic search, with no reimplementation of vector ops in TypeScript. +3. Mirrors the Python `wifi_densepose.client.*` surface (ADR-117 P4 — `python/wifi_densepose/client/ws.py`, `mqtt.py`, `primitives.py`) in TypeScript for parity across runtimes. +4. Integrates as a ruflo plugin via the `ruflo-plugin` manifest convention, exposing tools in the `mcp__rvagent__*` namespace callable by ruflo agents. +5. Ships strict TypeScript source, ESM + CJS dual output, Node.js 20+ minimum, type definitions in the tarball, zero bundler required. + +--- + +## 3.

Import succeeds. + +### P2 — MCP stdio server (2 weeks) + +**Goal**: `npx @ruvnet/rvagent stdio` connects to a running sensing-server over WebSocket + MQTT and exposes the tool catalog from §4.1 over stdio transport. + +- [ ] `src/server.ts` — create `McpServer` instance, register all tools from §4.1 with Zod input schemas. Tools that require a live sensing-server connection return a structured error `{ error: "SENSING_SERVER_UNAVAILABLE" }` rather than throwing, so the LLM gets useful context. +- [ ] `src/transports/stdio.ts` — `StdioServerTransport` entrypoint. Reads `RUVIEW_HOST` and `RUVIEW_PORT` env vars (default `localhost:8765` WS, `localhost:3000` REST, `localhost:1883` MQTT). +- [ ] `src/sensing/ws-client.ts` — TypeScript port of `python/wifi_densepose/client/ws.py`. Async generator yielding `SensingMessage` variants. Reconnect with exponential back-off (the Python client explicitly does not reconnect — the TS one should, because the stdio process is long-lived). +- [ ] `src/sensing/mqtt-client.ts` — TypeScript port of `python/wifi_densepose/client/mqtt.py` using `mqtt.js ^5`. Per-pattern callbacks, `topicMatches` wildcard helper. +- [ ] `src/sensing/primitives.ts` — `SemanticPrimitive` enum + `SemanticPrimitiveListener`.

Document this as a single-release compat shim. +- [ ] Remaining tools from §4.1: `ruview.vitals.get_breathing`, `ruview.vitals.get_heart_rate`, `ruview.pose.subscribe`, `ruview.primitives.list_active`, `ruview.primitives.subscribe`, `ruview.bfld.last_scan`, `ruview.bfld.subscribe`, `ruview.node.status`. +- [ ] Prompt template registrations from §4.3. +- [ ] Integration test: `curl -X POST http://localhost:3100/mcp` with a `tools/list` request; assert the response lists all 15 tools. +- [ ] Docker Compose entry for local fleet testing: `rvagent` HTTP container talking to `sensing-server` and `mosquitto` containers. + +### P4 — ruvector integration (1 week) + +**Goal**: `ruview.vector.search_pose` and `ruview.vector.store_pose` tools work end-to-end with a live HNSW index. + +- [ ] `src/vector/index.ts` — wrapper around `ruvector` napi-rs bindings. Initialise an HNSW index at server startup; expose `store(id, embedding)` and `search(embedding, k)`. +- [ ] Pose-to-embedding pipeline: when a `PoseDataMessage` arrives from the WS client, extract the 17-keypoint array, normalise to `[-1, 1]` per keypoint coordinate, flatten to a 34-dimensional float vector, store in HNSW with `node_id:person_index:timestamp_ms` as the ID. +- [ ] `src/vector/aether.ts` — AETHER-style cross-viewpoint search (ADR-024): given a pose embedding query, search HNSW index across all stored poses and return the top-k matches with their source node IDs. This enables cross-node person re-identification via the MCP tool without any network call between nodes. +- [ ] Verify that the `ruvector` napi-rs binary loads correctly on Node 20 linux/x86_64, macos/arm64, and windows/amd64. Document any platform-specific caveats. +- [ ] Index persistence: optional `RUVIEW_VECTOR_DB_PATH` env var. If set, persist the HNSW index to disk using `ruvector`'s serialise API.

The manifest registers the HTTP transport URL (configurable) and maps `mcp__rvagent__*` tool calls to the rvagent MCP server. +- [ ] `ruview` skill in `.claude/agents/` (CLAUDE.md §Available Agents): an agent description that documents the rvagent tool namespace for ruflo orchestration. +- [ ] `claude mcp add rvagent -- npx @ruvnet/rvagent stdio` tested against claude-flow MCP server on the local dev machine (ruvzen host on CLAUDE.local.md fleet). +- [ ] Document the fleet deployment pattern: run `npx @ruvnet/rvagent serve` on cognitum-v0 (Tailscale IP 100.77.59.83, port 50060 range to avoid conflict with existing services; see CLAUDE.local.md services table). Register the URL as a remote MCP server in `.claude/settings.json`. +- [ ] Publish announcement: link from project README (`docs/` link, not root README per CLAUDE.md rules). + +--- + +## 8. Open questions + +**Q1. npm package name availability** +`rvagent` (unscoped) does not appear in the npm registry as of 2026-05-24 based on search results. `@ruvnet/rvagent` is definitely available (the `@ruvnet` scope is owned by ruvnet per the npm profile page). Should the package be published unscoped (`rvagent`) for simpler `npx rvagent stdio` invocation, or scoped (`@ruvnet/rvagent`) for namespace clarity? The decision should be made before P5 because the npm name is permanent. + +**Q2. ruvector binary compatibility on Windows** +The `ruvector` npm package is a napi-rs native addon. The project's primary development machine (ruvzen) is Windows 11. It is not confirmed whether `ruvector@0.2.25` ships a prebuilt Windows binary in its npm tarball or requires a Rust toolchain to compile. If no Windows binary is shipped, developers on ruvzen would need the Rust toolchain installed to use `@ruvnet/rvagent`. This must be confirmed before P5 by running `npm install ruvector` on ruvzen. + +**Q3. ruvector TypeScript API stability** +ruvector `0.2.x` is not a 1.0 release. The HNSW insert and search API surface may change between minor versions. SENSE-BRIDGE P4 should pin `ruvector@~0.2.25` and document the version constraint explicitly. The question is whether ruvector publishes a changelog with breaking-change notices. + +**Q4. MCP tool call latency budget — RESOLVED** +Raw sensing frequency ≠ agent interaction frequency. If a tool call ever waits on the next CSI frame, agent orchestration latency becomes physically coupled to RF acquisition jitter, which is unacceptable at scale. The library MUST take option (a) — return from a continuous local cache: + +1. **Continuous local cache**: on startup the rvagent MCP server opens one WebSocket + one MQTT subscription per configured sensing-server endpoint and ingests every frame into an in-memory `Map` (plus parallel maps for `PoseDataMessage` and BFLD). Cache hits return in <1 ms regardless of CSI frame rate. +2. **Event-driven invalidation**: the cache entry's `received_at` timestamp is bumped on every received frame. The cache itself is never purged on a timer — only overwritten when fresh data lands, so a node that went quiet still serves its last-known value. +3. **Bounded freshness windows**: each tool accepts an optional `max_age_ms` argument (default 1000). If the cached `received_at` is older than `max_age_ms`, the tool returns `{ value: null, reason: "stale", last_seen_ms: N, threshold_ms: max_age_ms }` rather than blocking. The agent decides whether to accept the staleness, raise to the user, or escalate to a `ruview.node.status` health check. + +This pattern is required because P3's Streamable HTTP transport may serve dozens of concurrent agent sessions — see Q8. A shared cache + per-session freshness contract scales; per-session WS connections do not. + +P2 must implement this cache; P3 must verify that fanning the same cache to N concurrent HTTP sessions still maintains <1 ms median tool-call latency under load. + +**Q5. Subscription tool lifetime management** +Tools `ruview.pose.subscribe`, `ruview.primitives.subscribe`, and `ruview.bfld.subscribe` return a `subscription_id` and stream events. In the stdio transport there is one client, so this is straightforward. In the HTTP transport with multiple sessions, subscription state must be tracked per `Mcp-Session-Id`. When a session expires (HTTP 404) or is deleted via HTTP DELETE, the subscription must be cleaned up. The lifecycle mechanism is not fully designed — this is a known gap that P3 must close. + +**Q6. AETHER embedding dimension** +The ADR proposes a 34-dimensional pose embedding (17 keypoints × 2 coordinates). The actual AETHER embedding model (ADR-024) uses a learned contrastive encoder, not raw keypoints. If the AETHER ONNX model is available in the Rust workspace at P4 time, the embedding should use it. If not, the raw-keypoint approach is a reasonable placeholder. The question is whether `wifi-densepose-nn` exposes the AETHER encoder in a form that can be called from Node.js without bundling libtorch in the npm package. + +**Q7. ruflo plugin manifest format** +The ruflo plugin convention (`plugin/` directory in the ruflo repo) is not fully documented in a public spec as of this writing. The manifest format was inferred from the `ruflo-plugins.gif` directory listing and referenced in issue #952. Before P5, the actual plugin manifest schema must be confirmed from the ruflo repo so SENSE-BRIDGE does not ship an incompatible manifest. + +**Q8. MQTT vs direct WebSocket for Streamable HTTP transport** +In the stdio transport, rvagent holds a single WebSocket + single MQTT connection to the sensing-server. In the Streamable HTTP transport (potentially serving dozens of agent sessions), maintaining one connection per session is not scalable. The recommended pattern is a single shared connection per (sensing-server endpoint), multiplexed to all sessions. The implementation complexity of this fan-out is non-trivial and is not fully specified here. + +**Q9. Legacy SSE deprecation timeline** +The MCP `2024-11-05` SSE transport is deprecated in the current spec but Claude Desktop versions prior to the spec `2025-03-26` update still use it. SENSE-BRIDGE proposes `--legacy-sse` for one release cycle. The question is which specific Claude Desktop version drops legacy SSE support, and whether any of the active fleet nodes (cognitum-v0, cognitum-seed-1) run a Claude Desktop version old enough to need it. + +**Q10. Node.js vs Bun runtime** +The ruflo monorepo uses `bun` as the primary runtime (per `bunfig.toml` in `v3/`). Should `@ruvnet/rvagent` also support Bun? Bun's napi-rs compatibility for native addons like `ruvector` is improving but not guaranteed for 0.2.x. The P1 CI should test on Node 20 first; Bun support can be declared as a stretch goal for P5. + +--- + +## 9. Alternatives considered + +### Alt-A — Python-only client (extend ADR-117 with MCP bindings) + +Add `wifi_densepose.mcp` as a P6 module in the PIP-PHOENIX wheel (ADR-117). The Python MCP SDK (`mcp[cli]`) supports both stdio and HTTP transports and the PyO3 bindings give direct access to the sensing types. + +**Rejected because**: Python is not the dominant runtime for MCP server hosting in 2026 — the ecosystem tooling (Claude Desktop, Claude Code `mcp add`, ruflo) is TypeScript-first. A Python MCP server requires the full pip install including PyO3 bindings, which is a heavier install than `npx @ruvnet/rvagent stdio`. The ruflo plugin format is TypeScript. ADR-117 is already sizeable; adding MCP to it conflates two distinct concerns (Python developer library vs. AI agent interface). Python MCP remains a viable future addition (Q10 for a future ADR) but is not the right first-ship target. + +### Alt-B — Pure WebSocket/REST client without MCP framing + +Ship a TypeScript client library `@ruvnet/ruview-client` that wraps the sensing-server WebSocket and REST API without the MCP layer. Consumers who want MCP integration would wrap it themselves. + +**Rejected because**: it solves the connectivity problem but not the agent integration problem. Without MCP framing, Claude Code and ruflo agents cannot discover or call RuView capabilities through the standard `mcp__*` namespace — they would need custom prompt injection or bespoke tool definitions per agent. The whole value proposition of this ADR is that a single `claude mcp add rvagent` command makes all RuView primitives discoverable to any MCP-capable AI assistant. Splitting the library forces every consumer to re-add the MCP layer. + +### Alt-C — Embed MCP server inside the existing wifi-densepose-sensing-server Rust binary + +Add an MCP endpoint to the existing Axum server in `v2/crates/wifi-densepose-sensing-server/` (`v2/crates/wifi-densepose-sensing-server/src/main.rs`). This would use the `rmcp` Rust crate (Model Context Protocol SDK for Rust) and expose MCP over an additional port. + +**Rejected because**: (a) it couples the release cycle of the npm-hosted MCP interface to the firmware/Rust release cycle, which are on separate cadences — a new MCP tool that merely adds a JSON field should not require a firmware rebuild; (b) the ruflo plugin ecosystem is TypeScript and expects npm packages, not Rust binaries; (c) the ruvector vector layer is a napi-rs Node.js native module and cannot be called directly from a Rust process without going through the napi-rs server-side API, adding unnecessary complexity; (d) the sensing-server binary is already 15-30 MB stripped — adding the MCP endpoint and its JSON-RPC machinery would further bloat it. This alternative is worth revisiting if the Rust `rmcp` crate matures and the vector layer migrates fully to native Rust, but it is not appropriate for the first implementation. + +### Alt-D — Wrapping the existing ruflo WASM rvagent in a RuView shim + +The ruflo WASM rvagent (`rvagent_wasm_bg.wasm`) already exports `callMcp` / `executeTool` / `listTools`. One could define a RuView shim that registers custom tools into the ruflo WASM rvagent gallery. + +**Rejected because**: the ruflo WASM rvagent is an in-browser MCP *client* runner for the ruflo gallery, not a general-purpose MCP server that can expose sensing data. Its 13 exported functions are focused on template management and ruflo-gallery operations. Patching sensing tools into a browser WASM module is the wrong architecture for a server-side sensing bridge. The naming overlap is a reason to publish the new package promptly and clearly document the distinction. + +--- + +## 10. Compatibility + +### 10.1 Backwards compatibility with ADR-117 (PIP-PHOENIX) Python client + +SENSE-BRIDGE does not replace the Python client. Both can coexist: +- Python integrators use `from wifi_densepose.client import SensingClient` (ADR-117). +- TypeScript / MCP integrators use `import { SensingClient } from "@ruvnet/rvagent"`. +- MCP-capable AI assistants use `claude mcp add rvagent -- npx @ruvnet/rvagent stdio`. + +All three talk to the same sensing-server backend; there is no shared state between the Python and TypeScript clients beyond what the sensing-server itself maintains. + +### 10.2 Sensing-server API contract + +SENSE-BRIDGE depends on the sensing-server WebSocket protocol documented in `v2/crates/wifi-densepose-sensing-server/src/main.rs` (referenced in `python/wifi_densepose/client/ws.py:6-13`). The three message types (`connection_established`, `pose_data`, `edge_vitals`) are stable across v0.7.x releases. If the sensing-server adds new message types, SENSE-BRIDGE follows the same pattern as the Python client: unknown `type` values yield a plain `SensingMessage` rather than an error, ensuring forward compatibility. + +### 10.3 MCP protocol version + +SENSE-BRIDGE targets MCP protocol version `2025-06-18` (current stable). It will include backwards compatibility with `2025-03-26` (Streamable HTTP without session management) and optionally `2024-11-05` (legacy SSE via `--legacy-sse` flag). Protocol version `2025-06-18` requires the `MCP-Protocol-Version` header on HTTP requests; SENSE-BRIDGE validates this per spec. + +### 10.4 Node.js version + +Minimum Node.js 20 LTS. Node 22 is supported and recommended for production (active LTS as of 2026). The `ruvector` napi-rs bindings must be confirmed compatible with both (Q2). Node 18 is EOL and explicitly not supported. + +### 10.5 MQTT broker compatibility + +SENSE-BRIDGE uses `mqtt.js ^5` which implements MQTT 3.1.1 and MQTT 5.0. The `mosquitto` local broker (CLAUDE.local.md §Local mosquitto) and cognitum-v0's MQTT stack (CLAUDE.local.md fleet table) are both compatible. TLS mode is optional via `RUVIEW_MQTT_TLS=1` env var. + +--- + +## 11. Consequences + +### 11.1 Positive consequences + +- Any MCP-capable AI assistant can query RuView presence, vitals, pose, and BFLD data with zero custom integration code after `claude mcp add rvagent`. +- ruflo multi-agent swarms gain first-class access to real-world sensing data, enabling swarms to gate decisions on physical events (fall detected → page caregiver workflow). +- The TypeScript surface provides a second reference implementation of the sensing-server client protocol alongside the Python client (ADR-117), validating the protocol design against two independent consumers. +- The ruvector HNSW integration enables cross-node person re-identification entirely within the rvagent process — no additional network calls between sensing nodes. + +### 11.2 Negative consequences / risks + +| Risk | Likelihood | Severity | Mitigation | +|---|---|---|---| +| **ruvector napi-rs not building on Windows** | Medium | Medium | Confirm in P1 CI; if binaries not prebuilt, document requirement of Rust toolchain on Windows | +| **MCP protocol churn** — spec updated twice in 2025; another update in 2026 possible | Medium | Low | Pin `@modelcontextprotocol/sdk` to a minor range; wrap SDK calls behind an internal `transport.ts` abstraction so changes are isolated | +| **Subscription lifecycle bugs** — zombie subscriptions if session cleanup is missed | High | Medium | Implement per-session resource registry with TTL; all subscriptions auto-expire after `duration_s` even if session is not explicitly deleted | +| **sensing-server WS disconnect** — stdio process dies if not reconnecting | Low | High | Implement exponential back-off reconnect in `ws-client.ts`; emit `{ error: "RECONNECTING" }` tool responses during gap | +| **npm name collision** — `rvagent` taken by another publisher before P5 | Low | Medium | Publish `@ruvnet/rvagent` scoped; use that name throughout | +| **ruflo plugin manifest incompatibility** — format not publicly specced | Medium | Medium | Confirm format in P5 preparation; use the minimal required fields only | +| **Sensing-tool surface becomes a surveillance API** — "who is in the room" is a privacy-charged primitive | High | High | RUVIEW-POLICY layer (§4.1a) gates every sensing call; default-deny for biometric tools; redaction applied server-side so agents cannot opt out | + +### 11.3 Strategic implication: ambient-sensing normalization layer + +The MCP tool catalog in §4 is RuView-WiFi-CSI-specific today. The shape of the catalog — `presence.now`, `vitals.get_*`, `pose.latest`, `primitives.*`, `bfld.*` — is **modality-agnostic at the semantic layer**: the same tools could be backed by any sensing modality that produces the same questions. + +If the project later adds BLE, mmWave (e.g. the ESP32-C6 + Seeed MR60BHA2 already on COM4 per CLAUDE.md), LiDAR, thermal, camera, radar, or UWB inputs, the rvagent MCP surface stays the same. Only the source-multiplexer behind `cache.ts` changes — it now ingests from multiple modalities and resolves conflicts (e.g. WiFi CSI says "presence: true" but mmWave says "presence: false" → fusion policy decides; this is the kind of decision the RUVIEW-POLICY layer can also gate). + +This positions the npm package not as "a WiFi client" but as the **semantic-environment API**: agents ask "is anyone here?" without caring which radio answered. The competitive landscape (Aqara FP2, ESPHome LD2410) exposes raw telemetry; SENSE-BRIDGE exposes environmental cognition. + +The follow-on ADR (call it ADR-13x — RUVIEW-FUSION) would formalize the per-modality adapter contract.

Context + +### 1.1 The misunderstanding worth correcting once + +A naive integration tries to **push** data to a HomePod — open a socket, send a JSON-RPC, call an MQTT topic on `homepod.local`. Apple intentionally does not expose that surface. The HomePod is not an endpoint; it is the **Home Hub + Matter Controller + HomeKit Controller + Siri endpoint** for the Apple Home ecosystem on the LAN. It **discovers** accessories that advertise themselves on the local network via Bonjour/mDNS using the HomeKit Accessory Protocol (HAP) or Matter. + +The correct direction of flow is therefore: + +```text +RuView / Seed + ↓ (advertise HAP / Matter accessory on LAN) +HomeKit / Matter accessory + ↓ (mDNS discovery) +HomePod + ↓ (forwards to Apple Home automation graph) +Apple Home ecosystem (iPhone, Watch, Mac, Siri, automations) +``` + +### 1.2 What we ship today and where it stops + +ADR-115 ships an **MQTT auto-discovery publisher** that talks to Home Assistant. ADR-116's `cog-ha-matter` Cognitum cog wraps that publisher into a Seed-installable artifact with mDNS, an embedded rumqttd broker, RuVector-backed thresholds, and an Ed25519 witness chain. ADR-122 explicitly extends the same publisher with the BFLD presence / identity-risk / Soul-Match topics so a Home Assistant install sees them as auto-discovered entities. The current path to HomePod therefore runs: + +```text +RuView sensing-server ──► cog-ha-matter (MQTT HA-DISCO + HA-MIND) + ↓ + Home Assistant broker + ↓ + Home Assistant HomeKit Bridge add-on + ↓ + HomePod +``` + +This works and the auto-discovery is real, but it introduces a hard dependency: an operator must run Home Assistant, install its HomeKit Bridge integration, and pair the bridge in the Apple Home app. The Seed alone does not appear in Apple Home. + +ADR-116 §P7 anticipated this — the `cog-ha-matter` `Cargo.toml` already carries a `matter = []` feature stub with the comment "matter-rs is added in P7; intentionally absent in P1 to keep the dep surface small until the SDK choice is validated." This ADR closes that box. + +### 1.3 Why now + +Three forces line up in 2026-05: + +1. **The BFLD privacy gate (ADR-118 / 120 / 121) is shipped.** Class-2 and class-3 frames are the only ones eligible to cross the Matter boundary (ADR-122 §2.4). Without that gate we could not safely expose RuView signals to a consumer ecosystem. With it, every Anonymous / Restricted event is safe to advertise as a HomeKit sensor. +2. **`@ruvnet/rvagent` (ADR-124) is on npm.** The MCP surface that lets agents query RuView is live. A first-class Apple-Home presence widens RuView's reach from "agents that speak MCP" to "anyone with an iPhone and a HomePod" — the consumer wedge. +3. **The Cognitum Seed Docker image now bundles `cog-ha-matter`** (this branch's `Dockerfile.rust` change, see #794) — the runtime where a HAP advertiser would live is finally a single-image deployment. + +### 1.4 Strategic framing + +The combination is asymmetric: + +| Layer | RuView contributes | Apple Home contributes | +|-------|---------------------|------------------------| +| Sensing | Passive RF presence, breathing, heart rate, fall risk, BFLD identity-risk, through-wall occupancy, longitudinal wellness | (none — Apple has no native RF sensing surface) | +| Adoption | (limited — researcher-grade hardware today) | iPhone, Watch, Mac, HomePod, Apple TV installed base; consumer trust; voice; on-device intelligence | +| UX | (utility CLI + a Web UI) | Home app, Siri, automation engine, notifications, accessibility | +| Trust | Ed25519 witness chain, privacy class gate, local-first | Apple HomeKit local pairing, end-to-end encrypted, no cloud requirement | + +RuView supplies the **invisible cognition layer** Apple cannot provide on its own; Apple supplies the **distribution and UX** that an open sensing stack cannot bootstrap. Direct HAP integration removes the only structural barrier between those two layers — Home Assistant as a mandatory intermediary. + +--- + +## 2. Decision + +Ship a **native HomeKit / Matter accessory** in the Seed runtime so a freshly-imaged Cognitum Seed appears in the Apple Home app under `Add Accessory → More Options` with **zero Home-Assistant dependency**. + +Concretely: + +1. Add a `hap-accessory` workspace component that advertises a set of HomeKit characteristics over mDNS using HAP-1.1 (HomeKit Accessory Protocol). +2. The component subscribes to `wifi-densepose-sensing-server`'s WebSocket / BFLD `MqttEvent` stream and maps each privacy-class-2/3 event onto a HomeKit characteristic update. +3. The same Docker image that ships `sensing-server` and `cog-ha-matter` ships the new advertiser as a third entrypoint: + +```bash +docker run --network host ruvnet/wifi-densepose:latest hap-accessory --privacy-mode +``` + +`--network host` (or a macvlan bridge) is required because HAP pairing depends on the accessory and the controller seeing each other's mDNS broadcasts on the same L2 segment — same constraint Home Assistant's HomeKit Bridge has. + +### 2.1 Two implementation tracks (decided here together; ship 2.1.a first) + +#### 2.1.a — **HAP-python sidecar** (fastest to ship, lands first) + +Add a tiny Python entrypoint `bridges/hap-python/ruview_hap.py` using the well-maintained [`HAP-python`](https://github.com/ikalchev/HAP-python) library.

Single binary, no Python interpreter in the image, matches the all-Rust ethos of the Cognitum Seed (ADR-116 §1.4). + +### 2.1.c — **Topology: one HAP bridge, N child accessories** (decided) + +The advertiser publishes a **single HAP bridge** (`RuView Sense`) that owns N child accessories — one per logical sensor surface (presence-bedroom, presence-office, vitals-bedroom, semantic-events, …). Operators pair the bridge once; child accessories appear automatically and can be re-assigned to rooms in the Apple Home app. + +The alternative — N independent accessories each advertised separately — was rejected. It forces operators to pair RuView once per room (`RuView Bedroom`, `RuView Office`, `RuView Wellness`, `RuView Presence`, …), which becomes messy after the second or third room, and diverges from how every reference HomeKit accessory in the Home app behaves (a Hue bridge with bulbs, an Eve Energy bridge, etc.). Single pairing also makes container restart / re-image trivial — one persisted pairing key, not N. + +### 2.1.d — **Identity-risk mapping: semantic events, not probabilistic surveillance** (decided) + +`identity_risk_score` is a continuous 0..1 confidence from the BFLD identity-features pipeline (ADR-121 §2.6). It must NOT cross the HomeKit boundary as a raw value, and must NOT be wired to `SecuritySystemCurrentState`. Apple-Home users read security-system state as **"intruder detected"** — exposing a probability there turns RuView into surveillance UX with all the false-positive blame that entails. + +Instead, the bridge exposes **thresholded semantic events** that read like ambient awareness, not threat detection: + +| Semantic event | HomeKit primitive | Trigger (illustrative) | +|----------------|--------------------|-------------------------| +| `Unknown Presence` | `MotionSensor` (programmable; stateful) | BFLD class-2 presence + no matching SoulMatch oracle hit (ADR-121 §2.6) for > 30 s | +| `Unexpected Occupancy` | `OccupancySensor` (programmable) | Occupancy in a room outside its operator-defined "expected schedule" window | +| `Unrecognized Activity Pattern` | Programmable `Switch` (stateful, momentary) | BFLD longitudinal drift gate (ADR-118 §2.3 / ADR-122 §2.7) fires Reject or Recalibrate | + +What stays internal: + +- Raw `identity_risk_score` (numeric 0..1) — never published +- Soul-Signature match probability — never published +- `rf_signature_hash` — never published (already enforced by ADR-118 §2.5 / ADR-122 §2.4 — this is the structural invariant restated at the HAP boundary) + +The naming is the contract. "Unknown Presence" is *who's-here-and-it's-fine-but-worth-noting*; an end user will write an automation ("turn on the porch light when Unknown Presence is detected after 9pm") without ever thinking it accuses anyone of being an intruder. That semantic framing is the difference between RuView becoming the calm-tech ambient substrate Apple Home needs vs. another paranoid surveillance widget. + +This is the part of the ADR that determines whether RuView's HomeKit story ages well or generates the wrong kind of headlines. + +### 2.2 What we DO NOT do in 2.1.a or 2.1.b + +- **No Matter (CHIP) controller code.** Matter is the long-term play but its SDK in Rust is not yet stable and the certificate provisioning is heavy. HAP-1.1 over Bonjour gives 95% of the UX for 10% of the complexity, today. +- **No direct connection to the HomePod.** As the framing in §1.1 makes explicit, RuView never opens a socket to the HomePod. It advertises; the HomePod discovers. +- **No iCloud account binding.** HAP pairing is local-network-only by design — RuView gets adoption without ever touching Apple ID, which is a privacy story we keep cleanly. +- **No Class-0 (`Raw`) BFI exposure.** Structural invariant I1 (ADR-118 §2.2) holds. Only privacy-class-2 (Anonymous) and class-3 (Restricted) frames may be mapped onto HomeKit characteristics. The advertiser refuses to start in any other mode. + +### 2.3 Sequencing + +1. **P1** (this ADR-125 + 1 PR) — HAP-python sidecar (§2.1.a) lands as a separate entrypoint in the same Docker image. AC A1–A5 are gates. +2. **P2** (follow-up PR after operator feedback from 5+ Apple Home pairings) — Rust-native HAP (§2.1.b). Replaces P1; P1's `bridges/hap-python/` becomes an archived reference implementation. +3. **P3** (when matter-rs stabilizes) — Matter Controller path (still RuView-as-accessory, but using the Matter clusters rather than HAP-1.1 services). The Cognitum Cog gains a Matter QR code; pairing flow widens to "any Matter-capable controller, not just Apple." + +--- + +## 3. Consequences + +### 3.1 Wins + +- **Direct discoverability on Apple Home.** A Seed in the kitchen appears as `RuView Sense` in the Home app within seconds of `docker run`. No HA, no MQTT broker, no Home-Assistant HomeKit Bridge add-on. +- **Siri natively answers RuView questions.** "Hey Siri, is anyone in the kitchen?" — the question reaches the HomeKit characteristic without any custom skill or HA template sensor. +- **Apple-Home automations gain ambient triggers** RuView already produces (presence, breathing, fall, identity-risk) for free — they become first-class automation triggers in the Home app's UI. +- **Strategically corrects RuView's distribution problem.** The Apple Home installed base is the largest consumer surface for HomeKit-grade accessories. RuView's sensing IP becomes addressable to that base without an SDK port. +- **Closes ADR-116 §P7** — the long-flagged matter / HAP gap is now scheduled, not deferred indefinitely. + +### 3.2 Costs + +- **Python runtime in the Docker image (only for 2.1.a, until 2.1.b lands).** Adds ~30 MB to the runtime layer. Mitigation: P2 removes it; P1 isolates the Python dep in a side-stage so the sensing-server / cog-ha-matter layers stay clean. +- **Network-mode constraint.** HAP pairing needs the controller and accessory on the same L2 segment (mDNS broadcasts). Operators who run RuView in a container behind a NAT/bridge need `--network host` or a macvlan — same constraint HA's HomeKit Bridge has, but worth documenting. +- **Pairing state persistence.** HAP-python stores pairing data in a local file; that state must survive container restarts. Volume-mount `/var/lib/ruview-hap/` to a persistent location. + +### 3.3 Risks + +- **HAP-python maintenance.** The library is community-maintained; if it goes stale, P2 (Rust-native) absorbs the risk. 2.1.a is explicitly a stepping stone, not a long-term commitment. +- **Apple's evolving requirements.** HomeKit Accessory Certification is required to put a HAP logo on hardware, not to ship a software accessory that pairs locally. RuView's container deployment is squarely in the "uncertified developer accessory" lane, which Apple explicitly permits for local pairing. Worth restating in the operator README. +- **Privacy-class enforcement at the bridge boundary.** A bug that lets a class-0 BFI frame's data influence a HAP characteristic update would violate I1. Mitigation: the bridge consumes only the BFLD `MqttEvent` stream (which is already gated by `PrivacyGate` per ADR-120), never raw BFI; tests assert this in the same style as ADR-122 §4.3. + +### 3.4 Reversibility + +The advertiser is a separate entrypoint — pulling it out is `docker run` without the `hap-accessory` first-arg, identical to today's behavior.

Every prior RuView integration decision has been made with HA as a given constraint: ADR-115 built an MQTT auto-discovery publisher to fit inside HA, ADR-116 packaged it as a Cognitum Seed cog, ADR-122 extended it with BFLD presence events, and ADR-125 layered a native HAP bridge on top of the same stack. + +This approach yields functioning integrations, but it positions RuView permanently as a **guest in someone else's hub**. The architectural limits of Python HA are not just cosmetic: + +| Limit | Impact on RuView's roadmap | +|---|---| +| **Single-process Python GIL** | CSI DSP pipeline, BFLD analysis, and ruvector semantic search cannot run concurrently inside the HA process; they must run as external services connected over MQTT or WebSocket, introducing a round-trip on every sensor update | +| **Startup time (15–30 s on a Pi 5)** | The Cognitum Seed appliance restarts firmware-update-by-firmware-update; a 30 s hub startup on every OTA cycle is user-visible latency | +| **Memory footprint (300 MB+ idle)** | On a Pi 5 with 8 GB this is tolerable; on a Pi Zero 2 W or an embedded board with 512 MB it precludes co-location with the sensing stack | +| **No WASM safety boundary for integrations** | HA's 2,000+ community integrations are Python modules loaded directly into the HA process — one buggy integration can crash the hub or read arbitrary memory | +| **Recorder is structural only** | SQLite + InfluxDB store state history as rows; there is no semantic search.

HOMECORE fills that gap by porting the HA data model and API surface to Rust, replacing HA's Python internals with the RuView Rust crates, and wrapping community integrations in WASM sandboxes. + +### 1.3 What this ADR is *not* + +- Not a fork of the Python HA codebase. HOMECORE is a **clean-room Rust implementation** of HA's public API contracts and data model, not a line-by-line port. +- Not a replacement of the existing sensing stack. `v2/crates/wifi-densepose-*` remain authoritative. +- Not a deprecation of ADR-115/116/117/124/125. Those integrations continue to work with Python HA installs. HOMECORE is an additional deployment target, not a replacement mandate. +- Not a Matter SDK full-implementation. ADR-125 handles Matter; HOMECORE consumes the Matter bridge via the existing `cog-ha-matter` surface. +- Not a target for this quarter's sprint. HOMECORE is a multi-quarter initiative. This master ADR and its sub-ADRs define the architecture; implementation begins in P1. + +--- + +## 2. Decision + +Build **HOMECORE**: a native Rust + WASM + TypeScript implementation of the Home Assistant hub contract, integrated with the RuView sensing platform, the ruflo agent toolchain, and the ruvector vector layer. + +HOMECORE is wire-compatible with HA's REST and WebSocket APIs so that existing HA-native clients (the iOS/Android Home Assistant companion apps, HACS, Nabu Casa Cloud, and the HA voice satellite stack) operate without modification against a HOMECORE instance. + +HOMECORE is NOT a drop-in replacement on day one. The compatibility contract is phased (§6). The architecture is designed so that clients that work with HA today work with HOMECORE P3+. + +### 2.1 Codename rationale + +**HOMECORE** — the `core` of HA reimplemented at native speed, with the sensing stack at the center rather than at the periphery. + +--- + +## 3.

The state machine and event bus are the authoritative core (ADR-127). Integrations run in WASM sandboxes that communicate with the core via a defined ABI (ADR-128). The automation engine runs Rust-native trigger evaluation with a WASM expression evaluator for templates (ADR-129). The REST/WebSocket API layer is Axum-based and wire-compatible with HA (ADR-130). The frontend is TypeScript with the state machine compiled to WASM running in a SharedWorker (ADR-131). Historical state is stored in SQLite with ruvector for semantic search (ADR-132).

Cross-cutting decisions + +The following decisions govern all 8 sub-ADRs and are not repeated in each. + +### 5.1 Governance via RUVIEW-POLICY (ADR-124 §4.1a) + +Every HOMECORE component that returns biometric data (presence, HR/BR, pose keypoints, BFLD identity-risk) MUST route through the RUVIEW-POLICY layer defined in ADR-124 §4.1a. The policy store is the same `~/.config/rvagent/policy.json` used by `@ruvnet/rvagent`. HOMECORE is a first-class policy principal — its agent ID in the policy store is `homecore`. + +### 5.2 Semantic memory via ruvector + +Historical state is not only stored in SQLite rows (structural). Every state-changed event is also embedded via ruvector (using the same napi-rs bindings as ADR-124) and indexed in an HNSW store for semantic search. The `homecore-recorder` crate (ADR-132) owns this dual-write. Queries like "when did the living room motion last exceed baseline?" become vector-nearest-neighbour searches, not SQL BETWEEN clauses. + +### 5.3 Agent orchestration via ruflo + +The automation engine (ADR-129) and the assist pipeline (ADR-133) both have an optional ruflo-agent mode where complex conditions or voice intents are routed to a ruflo agent (using the `mcp__claude-flow__*` tool namespace) for LLM-backed resolution. This is gated by RUVIEW-POLICY: a policy grant is required before HOMECORE sends any state-history context to a ruflo agent. + +### 5.4 Witness and audit via Ed25519 chain (ADR-028 pattern) + +Every state transition that crosses a privacy boundary (e.g. BFLD identity-risk score elevated, a biometric entity state published) is logged to an Ed25519 witness chain using the same structure as ADR-028 §3. The witness bundle is exportable for regulated deployments (care homes, hotels, shared offices). + +### 5.5 Crate naming and workspace placement + +All HOMECORE crates live in `v2/crates/homecore-*/`: + +| Crate | ADR | +|---|---| +| `homecore` | ADR-127 | +| `homecore-plugins` | ADR-128 | +| `homecore-automation` | ADR-129 | +| `homecore-api` | ADR-130 | +| `homecore-recorder` | ADR-132 | +| `homecore-assist` | ADR-133 | +| `homecore-migrate` | ADR-134 | + +The frontend (`homecore-frontend`) is not a Rust crate — it is an npm package at `npm/homecore-frontend/`, mirroring the `npm/rvagent/` pattern from ADR-124. + +### 5.6 HA wire-compatibility baseline + +The HOMECORE REST and WebSocket API must be **compatible with HA 2025.1** as the baseline.

Alternatives rejected + +### Alt-A: Contribute RuView sensing features upstream to Python HA + +Add the HOMECORE features (WASM plugins, ruvector recorder, ruflo assist) as Python HA components via PRs to `home-assistant/core`. + +**Rejected because**: HA's architecture board has strict policies against adding new runtimes (WASM, Rust FFI) to the core process. The GIL bottleneck cannot be resolved from within Python HA. CSI DSP at 100 Hz frame rate inside a Python process is not feasible. This path cedes architectural control permanently. + +### Alt-B: Thin Rust wrapper that calls into Python HA via PyO3 + +Keep Python HA as the runtime; expose RuView sensing primitives via PyO3 bindings so they run at native speed inside the Python HA process. + +**Rejected because**: the GIL is not resolved by PyO3 calls — the HA event loop still serialises all state changes. Startup time and memory footprint are unchanged. WASM plugin safety is unchanged. This is a tactical optimisation, not an architectural solution. + +### Alt-C: OpenHAB or Domoticz as the base + +Port RuView's sensing stack on top of an alternative hub (openHAB/Java, Domoticz/C++). + +**Rejected because**: neither has HA's community network effects, companion app ecosystem, or HACS plugin catalog. A clean-room Rust implementation preserves the HA compatibility contract (the most valuable asset) without inheriting the Python runtime limitations. + +### Alt-D: Extend the existing `wifi-densepose-sensing-server` into a full hub + +Add automation, entity registry, and recorder features directly to the existing Axum sensing server. + +**Rejected because**: the sensing server is a purpose-built single-concern binary (CSI → MQTT/WebSocket). Expanding it into a hub would violate the single-responsibility principle and couple hub release cycles to firmware release cycles. HOMECORE is a separate crate family that depends on but does not modify the sensing server. + +--- + +## 9. Top-level risks + +| Risk | Likelihood | Severity | Mitigation | +|---|---|---|---| +| **API drift** — HA's REST/WS API evolves; HOMECORE must track it | High | High | Pin to HA 2025.1 baseline (schema 48); run the HA companion app integration tests against every HOMECORE release; ADR-130 owns the compat matrix | +| **WASM sandbox performance** — plugin calls through the WASM boundary add latency | Medium | Medium | Benchmark plugin roundtrip on Pi 5 before P3; reject if >5 ms; WASM3/Wasmtime both have sub-1 ms call overhead for compute-light integrations | +| **Core triad dependency** — ADR-128 and ADR-130 cannot start until ADR-127 is stable | High | High | ADR-127 is P2 start; freeze the state machine public API (entity_id, state, attributes, last_changed) before ADR-128 begins | +| **ruvector semantic recorder** — dual-write to SQLite + HNSW may impact write throughput under high-frequency sensing | Medium | High | ruvector writes are async (non-blocking tokio task); SQLite write is the hot path; benchmark at 100 state/s on Pi 5 before ADR-132 ships | +| **Nabu Casa gap** — users who depend on HA Cloud remote access have no HOMECORE replacement at P3 | High | Medium | Document Tailscale as the replacement prominently; provide ADR-134 migration wizard that detects Nabu Casa usage and offers Tailscale setup | +| **Frontend bundle size** — replicating the HA Lovelace card ecosystem in TS+WASM is a significant engineering effort | High | High | ADR-131 is off-critical-path; serve HA's Python frontend against the HOMECORE API until ADR-131 P3 ships | +| **License** — HA is Apache 2.0; the wire protocol is unencumbered; HA's UI assets and card components have separate licenses | Low | High | Clean-room Rust implementation does not use HA source; HA frontend is served as a binary (not embedded); review license before ADR-131 ships any reimplemented component | + +--- + +## 10. Open questions + +**Q1** (ADR-127): Should the HOMECORE state machine use a `DashMap` for lock-free concurrent reads, or a `RwLock>` for simpler reasoning? The answer affects every integration's write pattern. + +**Q2** (ADR-128): Does the WASM sandbox use Wasmtime (Cranelift JIT, ~5 MB binary) or WASM3 (interpreter, ~50 kB binary)? On a Pi 5 WASM3 is sufficient for integration logic; Wasmtime matters if integrations need near-native DSP speed. + +**Q3** (ADR-130): The HA WebSocket API uses numeric IDs for command/response correlation. The HA 2025.1 baseline adds `subscribe_trigger` as a first-class WS command. Are there any commands in the HA companion app that require a newer baseline? + +**Q4** (ADR-132): The ruvector HNSW index for state history — what embedding dimension represents a state snapshot? Options: (a) embed only numeric sensor states (scalar embedding), (b) embed `{entity_id, state, attributes}` as a text embedding via a local small model, (c) use a fixed schema encoding. The answer determines the semantic query fidelity. + +**Q5** (ADR-134): HA's `.storage/core.config_entries` format is versioned but undocumented; it is hand-engineered from reverse-engineering the Python `StorageCollection` class in `homeassistant/helpers/storage.py`. Is this format stable enough to parse without upstream documentation, or does HOMECORE need to maintain a version matrix? + +--- + +## 11.

Contains `bus` (EventBus), `states` (StateMachine), `services` (ServiceRegistry), `config` (Config), `components` (loaded component set). +2. **`EventBus`** — publish/subscribe event dispatch. `async_fire(event_type, event_data)` dispatches to all registered listeners. Listener registration is `async_listen(event_type, callback)`. Wildcard listener is `MATCH_ALL`. Event data is a plain Python dict. +3. **`StateMachine`** — an in-memory dictionary from `entity_id` (str) to `State`. `async_set(entity_id, new_state, attributes)` writes and fires `state_changed`. `get(entity_id)` reads. `async_remove(entity_id)` fires `state_removed`. States are immutable snapshots with `last_changed`, `last_updated`, `context`. +4. **`ServiceRegistry`** — maps `(domain, service_name)` → async handler function. `async_call(domain, service, data)` fires a `call_service` event, waits for the registered handler. `async_register(domain, service, handler, schema)` registers a handler with optional voluptuous schema validation. +5. **`EntityRegistry`** (`homeassistant/helpers/entity_registry.py`) — persists metadata (enabled/disabled, name override, area assignment, device ID, unique ID, entity category) across restarts. Stored in `.storage/core.entity_registry`. Loaded at startup; written on every change. + +The **DeviceRegistry** (`homeassistant/helpers/device_registry.py`, stored in `.storage/core.device_registry`) tracks physical devices that entities belong to.

These use Tokio typed broadcast channels with zero allocation on the read path. +2. **Integration events** (untyped): integrations fire arbitrary event types (`event_type: String`, `event_data: serde_json::Value`). These use a single `broadcast::Sender` where `DomainEvent` carries the type string and data blob. This mirrors HA's `EventBus.async_fire()`. + +### 2.3 Service registry: `HashMap` + mpsc dispatch + +Services are registered as `(Domain, ServiceName) → ServiceHandler` where `ServiceHandler` is a `Box BoxFuture + Send + Sync>`. The registry lives in a `tokio::sync::RwLock>`. Service calls go through the event bus (fire `call_service`) and are dispatched to the handler by an internal router task. This matches HA's indirection: `hass.services.async_call(domain, service, data)` does not call the handler directly; it fires an event. + +### 2.4 Entity registry: persisted metadata sidecar + +The entity registry is a `RwLock>` backed by an async JSON writer that flushes to `.homecore/storage/core.entity_registry` on every write. The schema matches HA's `core.entity_registry` schema (version 13 as of HA 2025.1) so ADR-134 migration can read both formats interchangeably. + +`EntityEntry` fields mirrored from HA: +- `entity_id: EntityId` +- `unique_id: Option` +- `platform: String` +- `name: Option` (user override) +- `disabled_by: Option` (user, integration, config_entry) +- `area_id: Option` +- `device_id: Option` +- `entity_category: Option` (config, diagnostic) +- `config_entry_id: Option` + +### 2.5 Device registry: parallel sidecar + +`DeviceRegistry` mirrors HA's `core.device_registry` schema (version 13). Devices are identified by a set of `(id_type, id_value)` tuples (the `identifiers` field), which matches HA's pattern of accepting multiple identifier types per device (MAC address, serial number, integration-specific ID). + +`DeviceEntry` and the in-memory `DeviceRegistry` are implemented. On server +startup, entity and device registry files are restored in deterministic key +order with a configurable hard row bound; malformed individual entries are +isolated and reported. + +--- + +## 3.

Open questions + +**Q1**: Should `EntityId` validation be strict (reject anything that doesn't match `[a-z0-9_]+\.[a-z0-9_]+`) or lenient (accept any UTF-8 string)? HA itself accepts unicode entity IDs since 2024.3. Strict validation simplifies routing; lenient matches HA's actual behaviour. + +**Q2**: The `broadcast::Sender` capacity of 4,096 is chosen based on a worst-case of 100 state writes/s × 40 s of acceptable lag before a slow receiver is declared dead. Is 40 s the right threshold, or should it be configurable per receiver? + +**Q3**: Should the `HomeCoreEntity` trait be object-safe (enabling `Vec>`) or use associated types (enabling monomorphisation)? Object safety is required for the WASM plugin boundary (ADR-128); monomorphisation is faster for built-in integrations. + +**Q4**: HA's `State.context` carries a `user_id` that traces which user or automation initiated a state change. HOMECORE uses `UserId` from the auth layer (ADR-130). Is the auth layer a dependency of the core state machine, or should `user_id` be an optional opaque string to avoid circular deps? + +--- + +## 8.

Security & concurrency review (P1 core, beyond-SOTA sweep) + +Foundational review of the `homecore` crate — the state store + event bus + +service/entity registries every other HOMECORE module trusts. Same rigor as +the ADR-129/130/132/133/161 sibling reviews. **Three real fixes (one +concurrency, two hardening), each pinned by a fails-on-old test; the bus-lag +and lock-discipline dimensions confirmed clean with evidence.** + +- **HC-RACE-01 (state-set TOCTOU — lost / reordered `state_changed`, the + crux). FIXED.** `StateMachine::set` did `get()` (releasing the DashMap + shard lock) → compute the next snapshot + the no-op / `last_changed` + decision → `insert()` (re-acquiring the lock) → `send()`. The + read-modify-write was **not atomic** w.r.t. a concurrent writer on the + same entity, contradicting §2.1's promise that "the writer atomically + replaces the map entry." A writer that read a stale `old` could + mis-classify a genuine transition as a no-op and **drop its + `state_changed` event** (a missed automation trigger) or fire an event + whose `new_state` duplicated the previously delivered one (a spurious + trigger for any automation keyed on `old_state != new_state`). **Fix:** + hold the shard write-lock across the entire read→decide→insert→fire + sequence via `entry()`/`insert_entry()`; `tx.send` is non-blocking, + non-async, and never re-enters the map, so firing under the shard lock + cannot deadlock and keeps global event order in lock-step with global + commit order. Pinned by `concurrent_set_fires_no_duplicate_adjacent_events` + (4 writers toggling one entity A/B; asserts no two consecutive fired + events carry an identical `new_state` — impossible under correct + serialisation; a probe observed ~93k such duplicate-adjacent events across + 200 trials on the racy code, zero on the fix). +- **HC-EID-LEN-01 (unbounded `entity_id` — memory-DoS at the REST boundary). + FIXED.** `homecore-api/src/rest.rs` parses untrusted path segments + straight through `EntityId::parse`; with no length cap, an + otherwise-valid id (`a.` + many MB of `[a-z0-9_]`) was accepted and a + `POST /api/states/` would persist it into the DashMap state store + (permanent growth across distinct ids). **Fix:** reject ids longer than + `MAX_ENTITY_ID_LEN` (255, HA-compatible) up front in `parse()`, before any + per-char scan, with a new `EntityIdError::TooLong`; fail-closed at the + boundary type protects every caller. Pinned by `entity_id_length_boundary` + (exactly-MAX accepted, MAX+1 and a 4 MiB id rejected — fails on old code). +- **HC-SVC-PANIC-01 (service-handler panic not isolated). HARDENED.** + `ServiceRegistry::call` already ran handlers outside the registry lock (no + `RwLock` poisoning, no blocking of other callers — clean), but a + panicking handler unwound through `call()` into the caller's task. **Fix:** + wrap the handler future in `AssertUnwindSafe` + `catch_unwind`, converting + a panic to `ServiceError::HandlerPanicked`; the registry stays fully + usable. Pinned by `panicking_handler_is_isolated_and_registry_survives`. + +**Dimensions confirmed clean (with evidence):** + +- **Event-bus bounds / lag (same class as the homecore-api WS lag-DoS).** + Both `StateMachine` and `EventBus` use bounded `tokio::sync::broadcast` + (capacity 4,096). A slow subscriber gets a recoverable `Lagged(n)` + (drop-oldest + re-sync); `fire_*` is non-blocking and **never waits on + slow receivers**, so a lagging subscriber cannot block the publisher, grow + the channel without bound, or take down a fast subscriber. Evidenced by + `slow_subscriber_does_not_block_publisher_or_kill_the_bus` (fire 3× + capacity at an idle subscriber; publisher unblocked, bus stays live). +- **Lock ordering / lock-across-await (deadlock).** No code path holds two + of `{state DashMap, registry RwLock, service RwLock}` simultaneously, so + no inconsistent-ordering deadlock can exist.

Compiles to a `.wasm` binary (from Rust, AssemblyScript, Go, or any WASM-targeting language). +2. Declares a `manifest.json` (superset of HA's manifest schema — see §3). +3. Exports exactly three WASM functions: `setup_entry(config_entry_ptr, config_entry_len) → i32`, `call_service(call_ptr, call_len) → i32`, and `receive_event(event_ptr, event_len) → i32`. +4. Imports a set of **host functions** from the HOMECORE host runtime: `hc_state_get`, `hc_state_set`, `hc_event_fire`, `hc_service_call`, `hc_log`, `hc_entity_register`. +5.

Context + +Home Assistant's automation system is defined across three components: + +1. **`homeassistant/components/automation/__init__.py`** — the automation manager: loads automation YAML, evaluates trigger platforms, calls the script executor when conditions pass. The core class is `AutomationEntity` which extends `ToggleEntity`. Automations are themselves HA entities with `state = on/off`. + +2. **`homeassistant/components/script/__init__.py`** — the script executor: a sequence of actions (service calls, conditions, delays, events, template variables, `choose`, `parallel`, `repeat`, `wait_for_trigger`). Scripts are entities too (`ScriptEntity` extends `ToggleEntity`). The execution engine supports five run modes: `single`, `restart`, `queued`, `parallel`, `ignore_first`. + +3. **`homeassistant/helpers/template.py`** — HA's Jinja2 customisation layer: wraps the upstream `jinja2` Python library with HA-specific globals (`states()`, `is_state()`, `state_attr()`, `now()`, `utcnow()`, `as_timestamp()`, `distance()`, `closest()`, etc.), custom filters (`regex_match`, `round`, `timestamp_local`), and a sandboxed `Environment` that prevents file I/O and dangerous evaluations. + +### 1.1 Scale and surface + +HA's automation YAML supports: +- **17 trigger platforms** (state, time, numeric_state, template, event, homeassistant, zone, geo_location, device, calendar, conversation, mqtt, webhook, tag, sun, time_pattern, persistent_notification) +- **7 condition types** (state, numeric_state, time, template, zone, sun, device) +- **22+ action types** (call_service, delay, wait_template, fire_event, device_action, choose, if, parallel, repeat, sequence, stop, set_conversation_response, ...) + +The YAML schema is validated by `voluptuous` schemas defined in `homeassistant/helpers/config_validation.py` (~5,000 lines). + +### 1.2 Jinja2 is the critical surface + +HA templates are used not only in automations but in dashboard cards, notification messages, and script variables. The HA frontend sends template strings to the API's `POST /api/template` endpoint for server-side evaluation. Any HOMECORE instance that claims API compatibility must execute Jinja2-compatible templates or existing automations will break. + +Full Jinja2 support in Rust without Python is non-trivial. The approach chosen here uses a **WASM-compiled MiniJinja** (the `minijinja` Rust crate compiled with HA-specific extension functions) rather than a full Python Jinja2 re-implementation. + +--- + +## 2. Decision + +Build the `homecore-automation` crate with three components: + +1. **YAML parser**: `serde_yaml` + custom validator that parses HA's automation and script YAML into typed Rust structs. Validates trigger, condition, and action schemas at load time. +2. **Trigger evaluator**: a Tokio task per loaded automation that subscribes to the HOMECORE event bus (ADR-127) and evaluates trigger conditions in Rust. When a trigger fires and conditions pass, it enqueues the automation action sequence. +3. **Action executor**: a script runner that processes action sequences. Service calls go to the HOMECORE service registry. Delays use `tokio::time::sleep`. Template evaluation uses MiniJinja. Complex conditions (optional) can route to a ruflo agent (ADR-133). + +### 2.1 Template evaluator: MiniJinja + HA-compatible extension functions + +`minijinja` (crates.io version 2.x) is a production-quality Jinja2 implementation in pure Rust. It is missing 5–10% of Jinja2's surface area (notably: `{% block %}` / `{% extends %}` template inheritance, and some Jinja2 Python-specific filters), but covers 100% of HA's automation template usage. + +HA-specific globals added on top of MiniJinja: + +```rust +env.add_global("states", minijinja::Value::from_function(ha_states_global)); +env.add_global("is_state", minijinja::Value::from_function(ha_is_state_global)); +env.add_global("state_attr", minijinja::Value::from_function(ha_state_attr_global)); +env.add_global("now", minijinja::Value::from_function(ha_now_global)); +env.add_global("utcnow", minijinja::Value::from_function(ha_utcnow_global)); +env.add_global("as_timestamp", minijinja::Value::from_function(ha_as_timestamp_global)); +env.add_global("distance", minijinja::Value::from_function(ha_distance_global)); +env.add_global("iif", minijinja::Value::from_function(ha_iif_global)); +``` + +Each global function reads from the HOMECORE state machine (ADR-127) via an `Arc` captured at environment construction time. Template evaluation is synchronous (MiniJinja is sync) but runs in a `tokio::task::spawn_blocking` wrapper to avoid blocking the async executor. + +### 2.2 WASM evaluator for untrusted template strings + +Dashboard card templates submitted via `POST /api/template` come from user-authored YAML, not first-party code. HA evaluates these in the same Python process, relying on Jinja2's `SandboxedEnvironment` for safety. HOMECORE uses a **WASM-sandboxed MiniJinja** evaluator: + +- A single WASM module (`homecore-template-eval.wasm`) is compiled from the MiniJinja crate with the HA extension globals stubbed to call host functions. +- Template strings are passed into the WASM module via the HOMECORE plugin ABI (ADR-128 §5.1). +- The WASM sandbox prevents file I/O, network access, and infinite loops (via Wasmtime fuel metering — 100,000 instructions per template evaluation). +- Result is returned as a string to the HOMECORE API. + +This is the same Wasmtime host already used for integration plugins (ADR-128) — no additional WASM runtime dependency. + +--- + +## 3.

Open questions + +**Q1**: MiniJinja does not support all Python-specific Jinja2 filters (e.g. `map`, `select`, `reject` with Python lambda arguments). HA's `homeassistant/helpers/template.py` adds custom equivalents of several of these. How many real-world HA automations use these filters? A corpus analysis of public HA configs on GitHub would answer this before P3 implementation. + +**Q2**: HA's `template` trigger supports a `value_template` that can reference `trigger.to_state`, `trigger.from_state`, and `trigger.for`. This requires passing trigger context into the template evaluation scope. Is this context threading straightforward in MiniJinja, or does it require a custom context type? + +**Q3**: The `conversation` trigger in HA uses the Assist pipeline's intent matching to fire automations based on voice commands. HOMECORE-ASSIST (ADR-133) owns the pipeline. Should the `conversation` trigger be implemented in ADR-129 (automation engine dependency on ADR-133) or in ADR-133 (assist pipeline fires automation events that ADR-129 listens to)? + +**Q4**: HA blueprints have a community sharing mechanism (blueprint.exchange). Should HOMECORE support importing blueprints from HA's blueprint exchange directly, or only local blueprints? + +--- + +## 8a. Security review (beyond-SOTA sweep, post ADR-154–159) + +A focused security review of `homecore-automation` (the execution/eval surface — triggers → conditions → actions, with templates) was run after the ADR-154–159 sweep, applying the same rigor that the sibling engine/bfld/calibration/vitals/geo reviews used. **Two real DoS findings, each pinned by a fails-on-old test; the condition-bypass, fail-closed-parsing, and action-authorization dimensions were probed and found clean.** + +- **HC-SEC-01 (template-injection / unbounded-expansion DoS, HIGH) — FIXED.** A `template:` condition / `value_template` is user automation config, and was rendered with MiniJinja's defaults: **no instruction budget, no output cap**. A single condition such as `{% for i in range(5000) %}{% for j in range(5000) %}xxxx{% endfor %}{% endfor %}` rendered a **100 MB string over ~11 s on one render call** (measured) — a CPU/memory denial of service (the bfld-class "unbounded expansion"; MiniJinja's per-call `range()` 10k cap does **not** stop nested loops). **Fix:** enable MiniJinja's `fuel` feature and set a per-render budget (`set_fuel(Some(1_000_000))`) so a nested loop burns one unit per iteration — the attack now fails fast (~90 ms) with "engine ran out of fuel"; plus a 64 KiB source-length cap rejecting pathological sources before compilation. Legitimate HA templates (a few dozen instructions) are unaffected. Pinned by `nested_loop_template_is_bounded_not_unbounded_dos`, `single_huge_repeat_template_is_bounded`, `oversized_template_source_is_rejected` (all fail-on-old: unbounded render / no rejection), and `legitimate_template_still_renders_within_fuel` (no regression). +- **HC-SEC-02 (panic-on-config DoS, MEDIUM) — FIXED.** `Action::Delay { seconds }` and `Action::WaitForTrigger { timeout_seconds }` fed the user-supplied float straight into `Duration::from_secs_f64`, which **panics** on negative, NaN, infinite, or overflowing inputs — all reachable from a crafted (or typo'd) YAML (`delay: {seconds: -1}`, `.nan`, `.inf`, `1e308`). One hostile config aborts the spawned automation run task with a panic (measured: "cannot convert float seconds to Duration: value is negative"). **Fix:** a `safe_duration_from_secs` guard that saturates instead of panicking (NaN/±inf/negative → `Duration::ZERO`, matching HA's lenient "non-positive delay = no delay"; absurdly large → clamped to ~100 years). Pinned by `delay_negative_seconds_does_not_panic`, `delay_nan_seconds_does_not_panic`, `delay_infinite_seconds_does_not_panic`, `wait_for_trigger_negative_timeout_does_not_panic`, `safe_duration_saturates_hostile_values` (incl. overflow clamp). + +**Dimensions confirmed clean (with evidence):** +- **Condition bypass / fail-closed eval** — a `Condition::Template` whose render errors evaluates to `false` (`condition.rs` `Err(_) => false`), and a `Choose` branch condition that fails to deserialize is treated as **non-matching** (the branch is skipped), not silently passing (`action.rs` `ChoiceBranch::matches` `Err(_) => return false`). Both fail **closed** (do-not-run), confirmed by the existing `choose_*` tests and template-false-blocks-action behavioral test. No true-by-default-on-parse-error path found. +- **Re-entrancy / livelock (DoS)** — run-mode machinery is bounded and tested: `Single`/`IgnoreFirst` re-entrancy guard, `Restart` cancel-and-replace, `Queued` FIFO serialization, and `max: N` semaphore cap (ADR-162; `restart_mode_cancels_prior_run`, `queued_mode_runs_sequentially_not_concurrently`, `max_two_caps_concurrency_at_two`, `single_mode_does_not_double_fire_on_rapid_triggers`). A self-triggering automation does not livelock the engine — each fire is bounded by its run-mode. +- **Action authorization** — templates are read-only sandboxed (`states`/`state_attr`/`is_state`/`now` globals; no service-call or state-set global is exposed to template scope), so a template cannot escalate into an action.

Context + +Home Assistant's HTTP and WebSocket APIs are the primary interface for every non-frontend client: the iOS companion app, the Android companion app, HACS, Node-RED, the `homeassistant` Python client library, ESPHome native API clients, external automation scripts, and the hundreds of third-party HA dashboard projects. + +The API surface is defined in two Python modules: + +1. **`homeassistant/components/api/__init__.py`** — 24 REST API routes mounted at `/api/`. Key routes: `GET /api/`, `GET /api/states`, `GET /api/states/`, `POST /api/states/`, `GET /api/events`, `POST /api/events/`, `GET /api/services`, `POST /api/services//`, `GET /api/error_log`, `GET /api/config`, `POST /api/template`, `POST /api/check_config`, `GET /api/history/period/` (deprecated — recorder), `POST /api/logbook/` (deprecated — recorder). + +2. **`homeassistant/components/websocket_api/`** — the WebSocket API handler (`connection.py` handles auth handshake; `commands.py` handles 30+ command types). Key commands: `auth`, `subscribe_events`, `unsubscribe_events`, `call_service`, `get_states`, `get_services`, `get_config`, `subscribe_trigger`, `render_template`, `validate_config`, `subscribe_entities` (entity registry updates), `config/entity_registry/list`, and many more. + +### 1.1 Auth model + +HA uses **long-lived access tokens (LLAT)** as the primary auth mechanism for non-UI clients. Tokens are created in the HA user profile UI and stored in `.storage/auth`. The REST API accepts `Authorization: Bearer ` or the `api_password` legacy header (deprecated since HA 2022.x). The WebSocket API requires an `auth` message with `access_token` as the first message after connection. + +### 1.2 Why wire-compat matters + +The iOS and Android HA companion apps (>100,000 installs combined) hardcode the HA API paths and WebSocket command schemas. Any implementation that deviates from the exact JSON schemas causes the apps to fail silently — not with a meaningful error, but by returning empty entity lists or missing state updates. Wire-compat is therefore a hard requirement, not a nice-to-have. + +The baseline for compatibility is **HA 2025.1** (the version that introduced SQLite recorder schema version 48). Any HOMECORE instance claiming compliance with this ADR must pass the companion app integration test suite. + +--- + +## 2.

Open questions + +**Q1**: The HA WebSocket API uses incremental integer IDs (`id: 1, 2, 3, ...`) for command/response correlation within a session. HOMECORE uses the same scheme. What is the maximum `id` value the companion app supports before wrapping? If the app doesn't wrap and HOMECORE processes > 2^31 commands per session, this becomes an overflow issue in extremely long-lived sessions. + +**Q2**: The `subscribe_entities` WS command (added in HA 2021.x) sends entity registry change events in addition to state change events. The iOS companion app uses this to maintain a local entity list without polling. Is the full `subscribe_entities` delta schema (including `action: "create" | "update" | "remove"`) fully documented, or must it be reverse-engineered from the companion app source? + +**Q3**: HA's `/auth/token` endpoint accepts `grant_type=password` (username/password) and `grant_type=refresh_token`. HOMECORE's initial implementation supports password grant only. Is refresh token support required for the companion app (it caches tokens between sessions) or does the companion app re-authenticate on each launch? + +**Q4**: CORS policy: HA's default CORS allows `http://localhost:*` and `http://homeassistant.local:*`. The HOMECORE-UI frontend (ADR-131) will be served from a different origin in development. What CORS policy should HOMECORE-API use in production vs development mode? + +--- + +## 8.

Context + +HOMECORE (ADR-126 through ADR-134) is the native Rust + WASM + TypeScript port of Home Assistant running as the hub on the Cognitum v0 Appliance. As of P2, the state machine ([ADR-127](ADR-127-homecore-state-machine-rust.md)), API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)), and COG runtime ([ADR-128](ADR-128-homecore-integration-plugin-system.md)) are in place. What is missing is a first-class dashboard UI that operators, integrators, and residents can use to manage the full two-tier hardware stack that HOMECORE coordinates. + +### 1.1 The two-tier hardware model this UI must represent + +This is the most important architectural constraint the UI must carry through every panel: + +- **Cognitum SEED** — a Pi Zero 2 W-based edge node. It has its own RVF vector store (8-dim, content-addressed, with kNN queries), Ed25519 witness chain, SHA-256 ingest audit trail, onboard environmental sensors (BME280 temperature/humidity/pressure, PIR motion, reed switch, ADS1115 4-channel ADC, vibration), 13 drift detectors, an MCP proxy (114 tools, JSON-RPC 2.0, default-deny policy), 98 HTTPS API endpoints, and epoch-based swarm sync for multi-SEED deployments. SEEDs sit close to the ESP32 sensing nodes and receive feature vectors from them at 1 Hz. Multiple SEEDs can form a peer mesh. **This is the sensing and memory tier.** +- **Cognitum v0 Appliance** — a Pi 5 + Hailo-10H hub, running at `:9000`. It hosts the COG runtime (`/var/lib/cognitum/apps/`), the HOMECORE state machine and event bus, the calibration service, `ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`, and acts as the fleet coordinator for multi-room correlation and federated training. The Appliance is where HOMECORE runs, and it is what the dashboard user is sitting in front of. **This is the computation and orchestration tier.** + +SEEDs are **subordinate nodes that the Appliance supervises** — they are not peers. The UI navigation hierarchy must reflect this: the Appliance is the root, SEEDs are children, ESP32 nodes are leaves. + +### 1.2 What the UI is not + +HOMECORE-UI is **not** a re-skin of the existing Cognitum Cog Store. It is a full operational dashboard that **extends** the Cognitum platform's shell — the Cog Store, API Explorer, and Guide already exist and must remain intact, with the HOMECORE dashboard added as a first-class navigation section alongside them. + +--- + +## 2. Decision + +Build HOMECORE-UI as a **complete** TypeScript + Rust→WASM frontend (per this ADR's §3 and the HOMECORE-127…134 family) that: + +1. Lives at `http://cognitum-v0:9000/homecore` (or as a dedicated nav item in the Cognitum Appliance shell). +2. Is visually and stylistically seamless with the existing Cognitum platform — same dark theme, same design tokens, same component patterns as `https://seed.cognitum.one/store`. +3. Drives the HOMECORE REST + WebSocket API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)) and the calibration HTTP API ([ADR-151](ADR-151-room-calibration-specialist-training.md)) for all data. +4. Updates in real-time via the homecore `subscribe_events` WebSocket channel. **The UI must never poll for entity state.** + +**This is a decision to deliver the complete operational dashboard — every panel in §4.1 through §4.10, every navigation section in §5, fully wired to live data — not a design-system scaffold or a partial first cut.** A static layout shell with placeholder data is explicitly **out of scope as a deliverable**: the design system (§3) is a means to the complete UI, not an end in itself. The acceptance bar for this ADR is that an operator can drive the full two-tier stack — fleet, entities, rooms, COGs, calibration, events, audit, and settings — from the dashboard, against real APIs, with no panel left as a stub. + +### 2.1 `homecore-server` is the single backend-for-frontend (BFF) gateway + +The data the dashboard needs is spread across **three backend tiers that are not one process**: (a) `homecore-api` (`/api/*` REST + `/api/websocket`, mounted in `homecore-server`); (b) the **calibration API** (`/api/v1/*`, served by a *separate* binary — `wifi-densepose calibrate-serve` / `wifi-densepose-sensing-server`); and (c) the **SEED device tier + appliance daemons** (RVF vector store, witness chain, onboard sensors, reflex rules, COG supervisor, federation), which are physically separate HTTPS services on the SEED nodes and the appliance. + +The browser must talk to **exactly one origin.** Therefore `homecore-server` is promoted to the **single BFF / API gateway** for HOMECORE-UI: it serves the static assets at `/homecore`, serves `homecore-api` at `/api/*`, and **adds a new `/api/homecore/*` namespace** that proxies and aggregates the calibration API and the SEED/appliance tiers server-side. The UI only ever issues same-origin requests; cross-service auth (SEED bearer tokens, calibration tokens) is held by the gateway and **never exposed to the browser**. This collapses the CORS/multi-port problem and gives one place to enforce the long-lived-access-token auth (§4.10). + +### 2.2 No mock data in production + +The in-browser mock layer that the first UI cut shipped behind DEMO banners (§7.1, prior revision) is **demoted to a dev-only fixture** gated behind an explicit `?demo=1` / `HOMECORE_UI_DEMO=1` flag. The production build wires **every** panel to a real gateway endpoint. The full endpoint contract and the backend work each panel needs are specified in **§11**; the staged path to get there is **§12**.

UI sections — required panels + +### 4.1 System Dashboard (the "home screen") + +The always-visible overview panel. Modelled on the API Explorer's live metric cards. All values update in real-time. + +- **v0 Appliance health strip** — reuse the exact metric-card pattern from `seed.cognitum.one/status`: one card each for CPU %, RAM usage, Hailo-10H inference load (% utilisation), Hailo temperature, uptime, and the running services (`ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`). Values in `--cyan`, labels in `--t2`. This strip is always at the top — it represents the machine the user is looking at. +- **SEED Fleet overview** — a grid of SEED node cards (one per paired SEED) on the `var(--card)` surface with `var(--border)`. Each card shows: online/offline status pill (green/red), firmware version, epoch number, current vector count, last ingest timestamp, and witness-chain validity badge. A collapsed row shows the SEED's 5 onboard sensors in summary (PIR: yes/no, door: open/closed, temperature from BME280). Offline SEEDs render the entire card with a `--red-d` background tint. Clicking a SEED card navigates to the SEED Detail view (§4.2). +- **ESP32 Node summary** — count of active ESP32 nodes per SEED, current frame rate (target: 100 Hz CSI + 1 Hz feature vectors), and a compact warning list for nodes with known issues (presence_score normalisation anomaly, stale firmware version). +- **COG Runtime status row** — a horizontal strip of status pills for each installed COG on the v0 Appliance. Pill colours follow the existing badge convention: `--green-d`/`--green` for running, `--red-d`/`--red` for failed, `--t3`/`--t2` for stopped. COG name in `--mono`. Clicking a pill navigates to COG Management (§4.6). +- **Event Bus activity indicator** — a small real-time sparkline showing the homecore broadcast channel event rate (events/sec). Indicate channel lag if a subscriber is falling behind the 4,096-event capacity. + +### 4.2 SEED Detail View (per-SEED drill-down) + +Accessible from the fleet grid. Full-page panel for a single SEED node, using the card + section-header pattern from the Cog Store's detail views. + +- **SEED identity header** — `device_id` in `--mono`, firmware version, paired status in green, USB vs WiFi connection mode. A section-header gradient border (cyan → purple, matching the featured card style) visually separates this from Appliance content. +- **Vector Store panel** — current vector count, dimension (8), last kNN query latency, current epoch number, a small sparkline of ingest rate over the last hour, and a storage budget bar showing usage against the 100K working-set target. A "Compact now" button (`POST /api/v1/store/compact`) in ghost style. When usage exceeds 80%, the bar renders in `--amber`. +- **Witness Chain panel** — chain length (SHA-256 entries), last verification timestamp, a one-click "Verify chain" button (`POST /api/v1/witness/verify`), and an "Export attestation bundle" button for regulated deployments. The Ed25519 custody attestation (device-bound keypair, epoch + vector count + witness head) renders here. Chain length in `--purple`, following the existing epoch/chain colour convention. +- **Onboard Sensors panel** — live readings from all 5 sensors in individual sub-cards: BME280 (temperature °C, humidity %, pressure hPa), PIR (motion boolean with last-triggered timestamp), reed switch (open/closed with last-changed timestamp), ADS1115 (4 analog channels with configurable labels), vibration (boolean with last-triggered). These are ground-truth validators against CSI readings and are critical for diagnosing false positives in the mixture-of-specialists. Sensor values in `--cyan`; sensor names in `--t2`. +- **Reflex Rules panel** — the 3 pre-configured rules with current state: `fragility_alarm` (threshold 0.3 → relay actuator), `drift_cutoff` (threshold 1.0), `hd_anomaly_indicator` (threshold 200 → PWM brightness). Show last-fired time for each. The `fragility_alarm` threshold is the most commonly adjusted field and should be editable inline. Rules that have recently fired render with a `--amber-d` background tint. +- **Cognitive Analysis panel** — boundary fragility score (0.0–1.0, from Stoer-Wagner min-cut on the kNN graph) rendered as a progress bar: green below 0.3, amber 0.3–0.6, red above 0.6. High fragility (>0.3) indicates a regime change in the environment and should be visually prominent. Temporal coherence phase boundaries shown as a labelled timeline of detected environment state transitions. kNN graph rebuild cadence indicator (every 10 s). +- **Ingest pipeline status** — which ESP32 nodes feed this SEED, the packet type each is sending (`0xC5110003` native feature vectors vs `0xC5110002` vitals fallback path — distinguished visually since native is preferred), current ingest batch size, flush interval, and bridge path topology (direct vs host-laptop hop). The bridge-hop warning (known architectural limitation) renders in `--amber` since it adds a network hop. + +### 4.3 SEED Fleet Map (multi-SEED topology) + +For deployments with more than one SEED, a topology view showing the mesh: + +- **Node hierarchy diagram** — v0 Appliance at root, SEEDs as second tier (grouped by room/zone), ESP32 nodes as leaves under each SEED. Lines represent active data flows. ESP-NOW mesh sync links between SEEDs shown as dashed lines. Connection health shown via line colour (green/amber/red). All labels in `--mono`. +- **Cross-SEED event deduplication indicator** — for events that span multiple SEEDs (one fall detected by two rooms; one occupant tracked through room A → hallway → room B), show a fusion badge indicating how many SEEDs contributed to the composite event. +- **Federation config** ([ADR-105](ADR-105-federated-csi-training.md)) — federated-learning round coordinator role (which SEED is the round coordinator), current round number, K healthy nodes selected, delta exchange status. **Model deltas only — never raw CSI** is a design invariant that must be labelled explicitly in the UI. + +### 4.4 Entity & State Browser + +The homecore state machine (`DashMap>`) is the authoritative source of truth. Every COG running on the v0 Appliance contributes entities. + +- **Entity list by domain** — grouped by the `domain.` prefix of `EntityId`, using collapsible section headers. The 21 entities per ESP32 node (11 raw + 10 semantic primitives from `cog-ha-matter`) are the most important set. For each entity: current state string (in `--t1`), last-changed timestamp (in `--t3`), attribute map as collapsible JSON in `--mono`, and the Context (`user_id` + `parent_id` causality chain, critical for care/audit deployments). Entity IDs always in `--mono`. +- **SEED provenance badge** — each entity carries a small badge showing its data lineage: which ESP32 node → which SEED → which COG → homecore state machine. This trace is invaluable for debugging false positives and is a **first-class UI element, not a collapsed detail.** +- **Domain filter + semantic search** — filter by domain prefix and, once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (homecore-recorder) lands, ruvector-backed semantic search: "when did the living room anomaly score last correlate with a door-open event?" A keyword filter across entity IDs and attribute keys ships in the initial release regardless of [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) status, given entity density; the semantic search layers on top once the recorder lands. +- **Real-time WebSocket feed** — entity states update live via the homecore `subscribe_events` WebSocket command ([ADR-130](ADR-130-homecore-rest-websocket-api.md)). The UI must never poll. Show a broadcast-channel lag indicator; warn visually if the subscriber is falling behind the 4,096-event channel capacity. +- **StateChanged detail panel** — clicking any entity opens a slide-over panel showing the full `StateChangedEvent`: `old_state`, `new_state`, `context.id`, `context.user_id`, and the `context.parent_id` chain rendered as a breadcrumb trail. + +### 4.5 RoomState / Sensing Panel + +Surfaces the mixture-of-specialists output from the calibration service — the highest-level per-room sensing result. Data comes from `GET /api/v1/room/state?bank=` on the v0 Appliance. + +- **Per-room cards** — one card per `room_id` on the `var(--card)` surface. Each card shows live `RoomState` JSON fields as sub-rows: presence (occupied/absent chip in green/red with confidence bar), posture (standing/sitting/lying chip with confidence), breathing BPM (numeric in `--cyan` with range indicator 6–30), heart rate BPM (numeric in `--cyan` with range indicator 40–120), restlessness score (0–1 progress bar), and anomaly score (0–1 with normal/anomalous label, bar turns red above a configurable threshold). +- **STALE warning** — when `stale: true` (the specialist bank was trained against a different baseline), render the entire room card with a `--amber-d` background tint and a prominent amber banner reading "Bank stale — baseline has changed" with a direct "Recalibrate room" link into the calibration wizard (§4.7). This is the most common real-world failure mode and **must never be subtle.** +- **VETO indicator** — when `vetoed: true` (anomaly veto suppressed vitals/posture because the window was physically implausible), render the affected specialist slots in `--red` with a "Veto active" label. Values suppressed by veto **must not render as zeros** — they must render as explicitly withheld. +- **Null specialist placeholders** — specialists not yet trained (`null` in the specialist bank) render as "Not trained" placeholders in `--t3` with a small "Calibrate to enable" prompt in ghost style. They are **not** errors. +- **Confidence bars** — each specialist output has a confidence float, shown as a small inline bar (`--cyan` fill) next to the reading. Low confidence (< 0.4) renders the bar in `--amber`. +- **Multi-SEED fusion indicator** — for rooms served by multiple SEEDs, show a small badge indicating how many SEED nodes contributed to the `MultiNodeMixture` for this room's reading. + +### 4.6 v0 Appliance COG Management + +The v0 Appliance hosts COGs at `/var/lib/cognitum/apps/`. This panel is the operational companion to the existing Cog Store (`seed.cognitum.one/store`). It must match the Cog Store's visual conventions precisely — same card layout, same category pills, same install/detail button pair — because operators will move between the two surfaces. + +- **Installed COGs list** — for each COG: `id` and `version` in `--mono`, architecture badge (`arm`/`hailo10` etc., category-pill pattern), status pill (running/stopped/failed/updating in green/grey/red/amber), `binary_sha256` verified badge (Ed25519 signature verification shown as a shield icon in `--green` or `--red`), and PID from the pid file. Actions: start, stop, restart (ghost style), and view `output.log` / `error.log` in a monospace drawer using `--mono`. Edit `config.json` inline with syntax highlighting. +- **COG Store / App Registry** — browsable `app-registry.json` listing. This panel should visually mirror `seed.cognitum.one/store` as closely as possible — same featured-card hero layout, same icon + title + description + category pill + action button structure. One-click install downloads the binary from GCS, verifies `binary_sha256` + `binary_signature`, writes the manifest, and starts the COG. Show which new homecore entities will appear in the state machine after install, as a preview list before confirming. +- **OTA Updates** — a badge count on installed COGs with available updates, matching the "Installed (N)" tab badge convention from the existing Cog Store. Show a diff panel (version change, new entities, config schema changes) before confirming the update. +- **Hailo HEF status** — for COGs with `arch: hailo10`: loaded HEF files on the Hailo-10H, current inference throughput, and `ruvector-hailo-worker:50051` connection status. The RF Foundation Encoder ([ADR-150](ADR-150-rf-foundation-encoder.md)) and neural pose head display here once available. + +### 4.7 Calibration Wizard + +The full baseline → enroll → train → verify pipeline runs via HTTP against the v0 Appliance ([ADR-151](ADR-151-room-calibration-specialist-training.md)). This is a multi-step guided flow — not a raw API panel. Use a stepped wizard layout with a progress indicator at the top (steps 1–5 as numbered pills, active step in `--cyan`, completed in `--green`, pending in `--t3`). + +- **Step 1 — Select room and SEED** — enter a `room_id` name (validated against `[A-Za-z0-9_-]{1,64}`) and select which SEED(s) and ESP32 nodes serve this room from a dropdown populated from the live fleet. Show current CSI ingest health for the selected nodes inline — if frames are not arriving at the expected rate, display an amber warning **before** allowing the operator to proceed. A broken ingest pipeline will silently fail calibration. +- **Step 2 — Baseline capture** — `POST /api/v1/calibration/start`. A large full-width animated progress bar (cyan fill) reads from `GET /api/v1/calibration/status`: frames recorded vs target, ETA in seconds, `z_median` value. If `motion_flagged` is true, overlay an amber banner: "Room must be empty — movement detected." The baseline UUID produced here is the anchor for all future STALE detection for this room — display it in `--mono` once complete so operators can record it. +- **Step 3 — Anchor enrollment** — the 8 anchor labels in enforced order: `empty`, `stand_still`, `sit`, `lie_down`, `breathe_slow`, `breathe_normal`, `small_move`, `sleep_posture`. For each: a human-readable instruction with an illustration, a countdown timer rendered as a circular progress ring in `--cyan`, and an immediate quality-gate result (accepted in green, retry in amber with a reason string). Drive via `POST /api/v1/enroll/anchor` + `GET /api/v1/enroll/status`. After each accepted anchor, show the extracted feature values (mean, variance, breathing_score, heart_score) in a small `--mono` data row so operators can sanity-check the capture. Show overall progress as "N / 8 anchors accepted." +- **Step 4 — Train** — a single `POST /api/v1/room/train` call. Show the 6 specialist results as a checklist: presence (threshold + occupied_var), posture (prototype count), breathing (min_score), heartbeat (min_score), restlessness (calm/active motion values), anomaly (prototype count + scale). Specialists that returned non-null render in `--green`. Null specialists (insufficient anchor data) render in `--amber` with a "Re-enroll missing anchors" prompt linking back to Step 3 for the specific missing labels. +- **Step 5 — Verify live** — display the live `RoomState` for the just-trained room using the same per-room card layout as §4.5. Prompt the operator to stand in the room and verify presence is detected, try sitting/lying to confirm posture, and breathe normally to confirm vitals are in plausible range. A "Confirm and save" button (cyan, primary) closes the wizard; a "Something's wrong — re-enroll" button (ghost) loops back to Step 3. + +### 4.8 Event Bus & Automation Feed + +- **Live event stream panel** — a virtualized scrolling list of `SystemEvent` variants (`StateChanged`, `EntityRegistered`, `ConfigReloaded`) and notable `DomainEvent`s from the homecore Tokio broadcast channel. Each row shows: event-type pill (coloured by variant), `entity_id` in `--mono`, old state → new state arrow, timestamp, and `context.user_id`. The stream is filterable by entity domain, event type, or source SEED/COG. The filter bar uses the same search-input style as the Cog Store's search field. +- **Context causality breadcrumb** — expanding any event row shows the full Context chain (`context.id` → `parent_id` → `grandparent_id`) as a breadcrumb trail in `--mono`. This is how automation loops become visible without any separate debugging tool. +- **Automation builder** ([ADR-129](ADR-129-homecore-automation-engine.md) scope) — a trigger → condition → action editor on the card surface. The most important RuView-specific trigger types to support are: `state_changed` on `RoomState` entities with a threshold expression (e.g. `anomaly.value > 0.8`), SEED reflex-rule firing events (`fragility_alarm`, `hd_anomaly_indicator`), and custom `domain_event` topics. Actions include calling services in the homecore service registry and firing domain events. The condition expression editor uses `--mono`. + +### 4.9 Witness / Audit Log + +- **Unified witness timeline** — a chronological merged view of events from both tiers: the SEED's SHA-256 ingest chain (every RVF store write attested) and homecore's Ed25519 state-transition chain (biometric crossings, BFLD identity-risk elevations). Each row: `entity_id` in `--mono`, old/new state, timestamp, source SEED `device_id`, signing key fingerprint (first 8 chars in `--mono`). Pagination uses the same "Showing X–Y of Z" convention from the Cog Store's cog grid. +- **Privacy mode banner** — a persistent top-of-panel banner showing current privacy mode: `--green-d`/green text for full-publish mode; `--amber-d`/amber text for audit-only mode (SHA-256 digests on-SEED only, no MQTT state messages). Show the per-SEED privacy mode state, since SEEDs can be individually configured. Toggling privacy mode is a high-stakes action — require an explicit "Confirm" step with a summary of what will change. +- **Export bundle** — an "Export attestation bundle" button (ghost) that packages the SEED witness chain + homecore Ed25519 chain as a downloadable archive for regulated-deployment (care home, hotel, shared office) compliance handoff. + +### 4.10 Settings & Integration Config + +- **SEED fleet management** — add, remove, and reprovision SEEDs. Show the USB-only pairing requirement prominently (the pairing window only opens via `169.254.42.1`, not WiFi — a security invariant). Per-SEED: `device_id` in `--mono`, firmware version, bearer token status, and a "Rotate token" action (ghost) that walks the operator through the secure token rotation flow. +- **ESP32 node provisioning** — per-node NVS config display (target IP, target port, node_id), last-seen firmware version, and a link to the provisioning script. The `node_id` → room/zone assignment is editable here and persists to the room calibration system's `room_id` mapping. +- **MQTT / cog-ha-matter config** ([ADR-116](ADR-116-cog-ha-matter-seed.md)) — broker URL, credentials (masked), MQTT topic prefix, mDNS advertisement status (`_ruview-ha._tcp`), and a live connection indicator (green dot for connected, red for unreachable). The 21 HA-DISCO entities per node are listed here with their `via_device` assignments showing which SEED they belong to in HA's device registry. +- **Long-lived access tokens** — for homecore-api companion-app connections (HA 2025.1 wire-compat, [ADR-130](ADR-130-homecore-rest-websocket-api.md)). Token creation, last-used timestamp, and revocation. The HA companion-app pairing QR-code flow surfaces here. +- **Federation config** — for multi-SEED deployments: ESP-NOW mesh sync status, cross-SEED epoch alignment values, and federated-learning round settings (coordinator SEED, round cadence, Krum aggregation parameters per [ADR-105](ADR-105-federated-csi-training.md)). The design invariant **"model deltas only, never raw CSI"** must be labelled explicitly in this panel. + +--- + +## 5. Navigation structure + +HOMECORE-UI must integrate into the existing Cognitum Appliance nav shell. The top nav should read: + +``` +Framework | Guide | Cog Store | HOMECORE | Status +``` + +— inserting **HOMECORE** as a first-class nav item between the existing "Cog Store" and "Status" entries, using the same nav-item style (text in `--t2`, active state in `--cyan` with bottom underline). + +Within the HOMECORE section, a left sidebar (or top sub-nav on narrow viewports) provides section navigation: + +``` +Dashboard | SEED Fleet | Entities | Rooms | COGs | Calibration | Events | Audit | Settings +``` + +The COG Store panel within HOMECORE (§4.6) links out to `seed.cognitum.one/store` for the full catalog view, ensuring the existing Cog Store remains the canonical browsing experience. + +--- + +## 6. Key UX invariants + +These must be maintained across every panel: + +1. **Always make the tier origin of any data explicit.** A `RoomState` reading traces to an ESP32 node → SEED → COG → v0 Appliance state machine. The provenance badge (§4.4) must appear wherever entity states are displayed. +2. **The `stale` and `vetoed` flags from `RoomState` and the kNN fragility score from SEED cognitive analysis are meaningful diagnostic signals** — they must never be silently hidden, styled grey-on-grey, or collapsed behind an expand toggle. They represent system health operators need to act on. +3. **Values that are `null` because a specialist has not been trained must be visually distinct from values that are unavailable due to an error.** The distinction is operationally important: `null` means "calibrate to enable," unavailable means "investigate." +4. **All entity IDs, hashes, API endpoints, binary signatures, device UUIDs, and JSON payloads must use `--mono` font.** This is already the convention in the API Explorer and must be consistent throughout HOMECORE-UI. +5. **The v0 Appliance Hailo HAT is a separate subsystem from the SEED's edge compute.** Inference results tagged as Hailo-sourced (COGs with `arch: hailo10`) must be visually distinguished from results from CPU-only COGs (`arch: arm`) so operators can triage hardware-specific failures. + +--- + +## 7. Scope — complete UI delivery + +The deliverable is the **entire** dashboard. Every panel below ships fully implemented and wired to its live data source — there is no scaffold-only milestone and no panel left as a placeholder. The table records each panel's authoritative backing API so the build can proceed in whatever order best fits the dependency graph; it is a dependency map, **not** a sequence of partial releases. + +| Panel | Section | Backing API / source | +|---|---|---| +| System Dashboard | §4.1 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) WebSocket + appliance health endpoints | +| SEED Detail View | §4.2 | SEED HTTPS API (vector store, witness, sensors, reflex, cognitive analysis) | +| SEED Fleet Map | §4.3 | fleet topology + federation ([ADR-105](ADR-105-federated-csi-training.md)) | +| Entity & State Browser | §4.4 | [ADR-127](ADR-127-homecore-state-machine-rust.md) state machine via [ADR-130](ADR-130-homecore-rest-websocket-api.md) `subscribe_events`; semantic search via [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) | +| RoomState / Sensing | §4.5 | [ADR-151](ADR-151-room-calibration-specialist-training.md) `GET /api/v1/room/state` | +| COG Management | §4.6 | [ADR-128](ADR-128-homecore-integration-plugin-system.md) plugin runtime + [ADR-100](ADR-100-cog-packaging-specification.md) app registry | +| Calibration Wizard | §4.7 | [ADR-151](ADR-151-room-calibration-specialist-training.md) calibration HTTP API | +| Event Bus & Automation | §4.8 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) broadcast channel + [ADR-129](ADR-129-homecore-automation-engine.md) automation engine | +| Witness / Audit Log | §4.9 | SEED SHA-256 ingest chain + homecore Ed25519 chain | +| Settings & Integration | §4.10 | SEED provisioning, [ADR-116](ADR-116-cog-ha-matter-seed.md) MQTT/Matter, LLAT, federation | + +### 7.1 Build sequencing within the complete deliverable + +The complete UI depends on backing services that mature on their own timelines. Each panel is built against the **real gateway endpoint** defined in §11; where the upstream is not yet available the panel renders a typed empty/error state, **not** fabricated data (the dev-only `?demo=1` fixture of §2.2 exists for offline development only and is never the shipped behaviour). Concretely, the hard contract dependencies are: [ADR-130](ADR-130-homecore-rest-websocket-api.md) (REST + WebSocket), [ADR-127](ADR-127-homecore-state-machine-rust.md) (state machine), [ADR-151](ADR-151-room-calibration-specialist-training.md) (calibration), [ADR-128](ADR-128-homecore-integration-plugin-system.md) (plugin runtime), [ADR-129](ADR-129-homecore-automation-engine.md) (automation), [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (event history + semantic search), [ADR-116](ADR-116-cog-ha-matter-seed.md) (SEED/Matter), [ADR-069](ADR-069-cognitum-seed-csi-pipeline.md) (SEED ingest), and [ADR-105](ADR-105-federated-csi-training.md) (federation). The keyword entity filter (§4.4) ships immediately; semantic search layers on once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) lands. The exact panel→endpoint→upstream map and the new gateway code each requires are §11; the staged delivery is §12. + +--- + +## 8. Consequences + +### 8.1 Positive + +- Operators, integrators, and residents get a single coherent surface for the full two-tier stack, replacing the need to SSH into SEEDs or hand-craft API calls. +- The dashboard reuses the proven Cognitum design tokens and component patterns verbatim, so it ships visually consistent with no separate design effort and no perceptible seam between surfaces. +- Diagnostic signals that today are invisible (`stale`/`vetoed` flags, kNN fragility, provenance lineage, channel lag) become first-class, surfacing the system's most common real-world failure modes directly to operators. + +### 8.2 Negative / risks + +- The UI hard-depends on the wire-compat guarantees of ADR-130 and the calibration contract of ADR-151; schema drift in either breaks panels silently. Integration tests against every backing contract in §7 are required. +- Committing to the complete UI in one deliverable is a larger up-front effort and couples the UI's readiness to the maturity of multiple backing services (§7.1, §11). The mitigation is the BFF gateway (§2.1): each panel targets one same-origin endpoint, and the gateway absorbs upstream churn behind a stable contract. +- Promoting `homecore-server` to a gateway means it now **proxies cross-tier traffic** (calibration API, SEED HTTPS, appliance daemons).

Context + +ADR-126 (the HOMECORE master) decided to reimplement Home Assistant (HA) natively in Rust. +HA persists every state change to a SQLite *recorder* database; downstream features +(history graphs, the logbook, long-term statistics, automation conditions that reference +past state) all read that store. HOMECORE therefore needs a durable state-history backbone. + +Two forces shape the decision: + +1. **Migration / coexistence.** Users adopting HOMECORE will have an existing HA + `recorder` database. Reusing HA's on-disk schema (rather than inventing a new one) lets + HOMECORE read an existing HA `home-assistant_v2.db` directly and lets HA-aware tooling + read HOMECORE's store. This is the same trust boundary that `homecore-migrate` + (ADR-165) handles for `.storage/*.json`. +2. **Semantic queries.** HA history is queried with SQL `BETWEEN`/`WHERE` clauses. The + HOMECORE platform already carries ruvector (ADR-124) for vector search, so the recorder + can additionally embed state changes and answer natural-language queries + ("which kitchen devices were warm at 3 PM?") via k-NN — a capability HA does not have. + +The recorder is the **durable-state surface**: if it is wrong, history, logbook, and +historical-condition automations are all wrong. ADR-164 flagged it as a CRITICAL coverage +gap precisely because such a load-bearing crate had no governing ADR. + +## 2. Decision + +Ship `homecore-recorder` as a SQLite state-history recorder with an HA-compatible schema +and an optional ruvector-backed semantic index, in three phases. P1 and P2 are built and +tested; P3 is planned. + +### 2.1 Storage — SQLite with the HA recorder schema (P1, shipped) + +- Persist via `sqlx` with the SQLite backend only (no Postgres, no TLS feature set). +- Mirror HA recorder **schema v48** so the store is bidirectionally readable + (`src/schema.rs`): + - `state_attributes` — shared attribute JSON blobs, deduped by an FNV-1a 64-bit hash + stored as a signed `i64` (matches HA's dedup key); + - `states` — one row per state write (`entity_id`, `state`, `attributes_id` FK, + `last_changed_ts`/`last_updated_ts` as REAL Unix seconds, `context_id` UUID); + - `events` — domain events (`event_type`, `event_data` JSON, `time_fired_ts`); + - `recorder_runs` — boot/shutdown bookends for history-gap detection. +- All DDL uses `CREATE TABLE IF NOT EXISTS`, so schema application is idempotent and safe + on every startup. +- Default persistence path `.homecore/home.db` (configurable). + +### 2.2 Capture — listener on the HOMECORE event bus (P1, shipped) + +- `RecorderListener` subscribes to the HOMECORE event bus (ADR-127) and captures + `StateChanged` events, writing snapshots through `Recorder` (`src/listener.rs`, + `src/db.rs`). +- A `DedupEngine` (`src/dedup.rs`) skips redundant writes when the state hash is unchanged, + matching HA's stateful-listener behaviour. + +### 2.3 Semantic search — ruvector HNSW (P2, shipped, feature-gated) + +- Behind the `ruvector` Cargo feature, the `Recorder` additionally calls a `SemanticIndex` + implementation (`src/semantic.rs`) that embeds state attributes and stores vectors in a + `ruvector-core` HNSW index for k-NN search. +- P2 embeddings are **hash-based** (sha2) — a deliberate, honest placeholder. They give a + working HNSW surface without claiming sentence-level semantic quality. +- When the feature is off, `NullSemanticIndex` satisfies the `SemanticIndex` trait bound + with no allocation, so the structural recorder ships independently of ruvector. + +### 2.4 Real sentence embeddings (P3, planned — not yet built) + +- Replace the hash embeddings with ruvector-attention sentence embeddings (dim → 384). Not + implemented; tracked as a follow-up. The README and `Cargo.toml` label this P3 explicitly. + +### 2.5 Test evidence (as shipped) + +- P1: 14 tests (`cargo test -p homecore-recorder --no-default-features`). +- P2: 20 tests (`cargo test -p homecore-recorder --features ruvector`). + +## 3. Consequences + +**Positive.** + +- HA-schema compatibility makes migration (ADR-165) and coexistence cheap: HOMECORE can + read an existing HA `recorder.db`, and any SQLite tool can read HOMECORE's history. +- The semantic index is **additive** and feature-gated: the durable structural recorder has + no hard dependency on ruvector, so the storage backbone ships first. +- Standard SQLite means no proprietary export format; history is directly queryable. + +**Negative / honest limits.** + +- P2 semantic search uses **hash embeddings**, not real sentence embeddings — query quality + is limited until P3. This is disclosed in the crate docs and here; it must not be cited as + semantic-quality-validated. +- No per-crate benchmarks exist yet; the latency figures in the README + (state-write p50 < 2 ms, semantic search < 10 ms on 1 M records) are design targets / + estimates, **needs verification** with a criterion baseline. +- Pinning to HA schema v48 couples HOMECORE to a specific HA recorder schema generation; + future HA schema bumps require an explicit migration step. + +**Neutral.** + +- This ADR governs the recorder crate only. The query/REST surface over recorder data is + HOMECORE-API (ADR-130, P3); automation conditions on historical state are + HOMECORE-automation (ADR-129, P3). + +## 3a. Security review (2026-06, post-ADR-154–159 sweep) + +A beyond-SOTA security review of `homecore-recorder` covered SQL injection, retention/purge +correctness, fail-closed write integrity, semantic-store NaN poisoning, and PII exposure. + +**Confirmed clean (with evidence):** + +- **SQL injection — clean.** Every query in `db.rs` uses bound `?` parameters; no user- or + entity-influenceable value is interpolated into SQL via `format!`/concatenation. The only + `format!` builds the `LIKE` *pattern* string, which is itself **bound** as a parameter with + `ESCAPE '\\'` and `% _ \` escaping — so a metacharacter payload is matched literally. Pinned + by `malicious_entity_id_is_stored_literally_not_executed` (a `'; DROP TABLE states; --` state + value leaves the table intact and round-trips verbatim) and + `like_metacharacters_in_query_are_literal_not_wildcards`. +- **NaN-index poisoning — structurally impossible.** Embeddings are SHA-256 → `i32` → + `f32`; an `i32`→`f32` cast is always finite (never NaN/Inf), and an all-zero-digest is + guarded by the `norm > 1e-10` check. Empty-index search, empty-string query, and `k=0` were + probed and all return `Ok(0)` with no panic. (Unlike the calibration/vitals/geo paths, no raw + sensor float ever reaches the index.) +- **Fail-closed writes.** A removal event returns `Ok(None)`; semantic-index failure is logged, + not propagated, so it never blocks the durable SQLite write; `EntityId` parse failure falls + back to a sentinel rather than panicking. + +**Fixed (real bounding bugs):** + +- **Memory-DoS — `get_state_history` was unbounded.** No `LIMIT`, so a wide time window over a + high-frequency entity loaded an unbounded row set into memory. Now capped at + `MAX_HISTORY_ROWS` (1,000,000); sibling search paths were already `k`-bounded. +- **Startup state restoration.** `latest_states(limit)` selects one newest row + per entity with `(last_updated_ts, state_id)` tie-breaking, orders results by + entity ID, and caps requests at 100,000. Malformed rows are skipped with + typed warnings. `restore_latest` preserves recorded timestamps and installs + snapshots with a `homecore.restore` context before the recorder listener and + automation engine start. +- **Disk-DoS / documented-but-missing `purge`.** The README advertised `Recorder::purge`, but + no retention path existed → unbounded disk growth. Added a **transactional** `purge(older_than)` + with an **exclusive** cutoff (idempotent, no off-by-one) that deletes old `states`/`events` and + GCs orphaned `state_attributes` blobs (dedup-shared blobs kept until their last referrer is gone). + +`homecore-recorder` tests: 19 → 25 (`--no-default-features`) / 25 → 31 (`--features ruvector`), +0 failed.

Questions & Answers + +### Q1 — Why not reuse HA's existing `homeassistant.helpers.intent` via PyO3? + +PyO3 bridges add a GIL lock on every cross-language call; the Assist pipeline processes +hundreds of short utterances per day from voice satellites. A native Rust recognizer is +simpler and faster. Python HA can still connect as an external integration via MQTT or +the HOMECORE WebSocket API. + +### Q2 — How does `RegexIntentRecognizer` handle ambiguity? + +Patterns are tried in registration order; the first match wins. Slot extraction uses +named capture groups. A future P2 upgrade can run all patterns, score them by slot +completeness, and return the highest-scoring match. + +### Q3 — Windows subprocess teardown (ruflo runner subprocess on Windows) + +`tokio::process::Child` on Windows does not automatically kill the child process when +the `Child` struct is dropped — `SIGTERM` is not a Windows concept, and `TerminateProcess` +is not called automatically. Options for P2: + +1. Call `child.start_kill()` in a `Drop` impl (requires a `Runtime` handle — tricky in sync Drop). +2. Wrap `Child` in an `Arc>>` and call `kill()` in an `async fn shutdown()`. +3. Use a Windows job object to bind the subprocess lifetime to the parent process. + +**P2 decision**: implement option 2 (explicit `async shutdown()`) + register a `tokio::signal` +handler for `Ctrl+C` / `SIGINT` that calls `shutdown()` before exit. Document the Windows caveat +in the crate README and in `runner.rs`. Job object approach (option 3) is deferred to P3 only +if option 2 proves insufficient in fleet testing. + +### Q4 — Why is `SemanticIntentRecognizer` a P2 stub? + +The ruvector HNSW index requires the vector store to be populated at startup with intent +exemplars. That startup path requires deciding on a serialization format (HNSW index files +vs. an in-memory array at compile time), which intersects with ADR-084 (RabitQ) and ADR-067 +(ruvector v2.0.5). P2 will define the exemplar format and populate the index. + +--- + +## 4. Consequences + +- **Positive**: HOMECORE-API `assist` WebSocket command gets a functional backend. +- **Positive**: Ruflo LLM pipelines can upgrade intent matching by swapping the `RufloRunner` impl. +- **Positive**: P1 ships with zero new heavy dependencies (no subprocess spawning, no ML runtime). +- **Negative**: Regex matching has limited coverage; long-tail utterances will return "I'm not sure". +- **Deferral**: ruvector semantic recognizer and real subprocess runner both land in P2. + +--- + +## 5.

Security review (beyond-SOTA, untrusted-input → action path) + +A focused security review of the Assist pipeline — `utterance → recognizer → +intent → handler → action`, plus `RufloRunner` — treating the utterance as +untrusted input (voice transcripts, the WebSocket `assist` command). This +surface was not covered by the ADR-154–159 sweep. + +### 6.1 Finding fixed — HC-ASSIST-01 (unbounded-utterance DoS, LOW) + +Both `RegexIntentRecognizer::recognize` and the semantic `recognize_scored` +accepted utterances of **unbounded length** and ran `to_lowercase()` (a full +clone) + a per-registered-pattern scan (and, in the semantic path, full +tokenisation + feature-hash embedding) before any bound — an allocation/CPU +amplification on attacker-controlled input. The `regex` crate is **linear-time** +(RE2-style finite automaton, no catastrophic backtracking), so this was a +throughput/memory DoS, not a hang. + +**Fix:** `MAX_UTTERANCE_BYTES = 4096` (far above any real spoken command), +checked at **both** recognizer boundaries *before* any allocation/scan. An +over-length utterance **fails closed** to `Ok(None)` — no intent, no action, +identical to an unrecognised phrase — so it can never be coerced into firing a +handler. Pinned by `over_length_utterance_fails_closed` (an over-length +utterance that *contains* a valid command resolves to `None`, which would have +matched on the old code) and `over_length_utterance_fails_closed_semantic`. + +### 6.2 Dimensions confirmed clean (with evidence) + +- **Command / argument injection — NO SUBPROCESS SURFACE.** The `RufloRunner` + has exactly two impls: `NoopRunner` (no process) and `LocalRunner` (runs the + local recognizer, no process).

The real gain is measurement SNR: 4.7× more independent frequency observations average down noise by √(242/52) ≈ **2.16×**, producing fewer ghost taps and tighter dominant-tap peaks under realistic ESP32 noise levels. + +### 1.3 Why CIR Now + +The multistatic coherence gate in `ruvsense/multistatic.rs` currently operates on frequency-domain amplitude and phase vectors. The pseudocode in the architecture document calls `link_gates[i].is_coherent(cir)` — passing a CIR, not a raw CSI frame. Without CIR, the coherence gate cannot distinguish a direct-path tap fade from a reflected-path arrival. Without CIR, `ruvsense/tomography.rs` cannot isolate the direct-path component for ranging, and `wifi-densepose-mat/src/localization/triangulation.rs` cannot perform time-of-arrival triangulation. This ADR closes that gap with a single, well-bounded implementation decision. + +--- + +## 2. Decision + +### 2.1 Chosen Algorithm: ISTA with a DFT Dictionary (L1-Regularized Sparse CIR Recovery) + +The primary CIR estimator is **ISTA** (Iterative Shrinkage-Thresholding Algorithm) with an L1 penalty and a delay-domain DFT dictionary, implemented by wrapping the existing `ruvector-solver::NeumannSolver`. This is not zero-padded IFFT. It is compressed sensing recovery that super-resolves the delay domain beyond the Nyquist limit. + +The problem: given the measured frequency-domain CSI vector `H ∈ ℂ^K` (K = 56 or 114 or 256 subcarriers), find the sparse delay-domain representation `x ∈ ℂ^G` (G > K, a finer delay grid) such that: + +``` +minimise ‖H - Φx‖₂² + λ‖x‖₁ +``` + +where `Φ ∈ ℂ^{K×G}` is a sub-DFT dictionary matrix with columns `φ_g = [1, e^{-j2πΔf·τ_g}, …, e^{-j2π(K-1)Δf·τ_g}]^T`, and `τ_g` are the delay-grid points spaced at `1/(G·Δf)`. For ESP32-S3 HT20 with K=56, Δf=312.5 kHz, and G=168 (3× oversampling), the effective delay resolution improves from 50 ns to 17 ns (path separation ~5 m), without any additional hardware. + +ISTA is already the algorithmic pattern used in `ruvsense/tomography.rs` for voxel-space reconstruction. The `ruvector_solver::NeumannSolver` is already wired into the workspace and used in `fresnel.rs:280` and `train/subcarrier.rs:225`. There is no new dependency. + +### 2.2 Why Not the Alternatives + +The table below is the decision record, not a menu of supported options. + +| Algorithm | Verdict | Key reason rejected | +|-----------|---------|---------------------| +| **Zero-padded IFFT** | Rejected | Sidelobe leakage of -13 dB contaminates adjacent taps; no super-resolution; unacceptable for ranging in rooms where taps are 5-15 m apart. CIRSense (arXiv:2510.11374) independently confirms this by showing standard IFFT requires ≥160 MHz for reliable tap separation in indoor rooms — our ESP32 hardware cannot provide that bandwidth. | +| **ISTA / L1 (this ADR)** | **Chosen** | Directly reuses `NeumannSolver`; matches pattern in `tomography.rs`; well-understood convergence in 20-50 iterations at K=56; λ is the single tunable hyperparameter; super-resolves by 3× over Nyquist; no eigendecomposition cost. | +| **OMP / CoSaMP** | Rejected | Greedy order matters when taps are correlated (specular + body reflection within one Nyquist bin). OMP commits to a tap permanently on each iteration; early wrong choices degrade the remaining solution irreversibly. ISTA's continuous shrinkage avoids this. ISTA and OMP yield similar results at high SNR; at low SNR (NLOS links, distant nodes) ISTA is measurably better per Chronos (NSDI 2016) and the pulse-shape paper (arXiv:2306.15320). | +| **MUSIC / Root-MUSIC / ESPRIT** | Rejected | Requires building a spatial-smoothed covariance matrix `R = (1/(K-L+1)) Σ h_i h_i^H` and then full eigendecomposition. On the aggregator this is O(L³) per link per frame. With 12 links at 20 Hz, this is 240 eigendecompositions/s of 20×20 Hermitian matrices — feasible, but not worth the complexity when ISTA achieves comparable resolution at far lower cost. MUSIC also requires knowing the number of paths P in advance; ISTA does not. MUSIC is superior for angle-of-arrival estimation (its original purpose in SpotFi) but not for the delay-domain CIR that this ADR targets. | +| **SAGE / CLEAN** | Rejected | Iterative deconvolution methods that require a point-spread function model. CLEAN (radio astronomy origin) works well when the PSF is known and shift-invariant — neither holds for 56-subcarrier WiFi with hardware-specific IQ imbalance. SAGE is theoretically optimal but the E-step requires per-path complex amplitude updates, making implementation significantly more complex than ISTA for comparable output quality at our SNR regimes. | +| **Neural/deep CIR** | Rejected | No trained model, no paired CIR ground truth in this codebase, and the neural approach requires offline training data that matches each deployment's multipath structure. The 2024-2025 literature on neural CIR (arXiv:2601.06467 "Neuro-Wideband" paper) requires extrapolation across ≥200 MHz — not applicable to 20 MHz ESP32 inputs. Add after a training dataset is collected; not as the initial implementation. | +| **Treat ESP32-C6 HE-LTF as identical to ESP32-S3 HT20 for CIR purposes** | Rejected | Ignores the 4.7× subcarrier count difference (242 vs 52 K_active). Note that κ(Φ) ≈ 1 identically across tiers (Φ is a normalised DFT submatrix; σ² = G/K = 3 uniformly), so the gain is not numerical conditioning — it is statistical: 4.7× more independent frequency observations suppress noise by 2.16×, producing fewer ghost taps and higher `dominant_tap_ratio` stability. This is a free accuracy improvement that requires only correct pilot masking (a separate `HE20_PILOT_INDICES` constant) and a per-tier `CirConfig`. Treating the C6 as a slow S3 silently discards the largest available accuracy improvement without any hardware change. | + +### 2.3 Per-Bandwidth Strategy + +There is one algorithm for all tiers, parameterised by bandwidth. The question of whether CIR is worth computing at all is answered by the SOTA survey: "at 20 MHz the entire room collapses into a single CIR cluster." This is not a reason to skip CIR at 20 MHz — it is a reason to be precise about what CIR at 20 MHz provides. + +| Tier | K_active subcarriers | G delay bins (3×) | Effective delay res. | Path sep. | Recommended λ | Iterations | +|------|---------------------|--------------------|---------------------|-----------|----------------|------------| +| A-HE (HE20, ESP32-C6) | 242 | 726 | ~17 ns | ~5 m | 0.03 | 32 | +| A (HT20, ESP32-S3) | 52 | 168 | ~17 ns | ~5 m | 0.05 | 30 | +| B (HT40, ESP32-S3) | 108 | 342 | ~9 ns | ~2.7 m | 0.03 | 35 | +| C (HT80, Nexmon) | 242 | 768 | ~4 ns | ~1.2 m | 0.02 | 40 | + +Tier A-HE uses 802.11ax HE-LTF subcarrier spacing (78.125 kHz in HE-SU 20 MHz) and 802.11ax pilot pattern (8 pilot subcarriers per 802.11ax spec, distinct from the HT20 pilot pattern at ±7, ±21). The resulting K_active matches Tier C in count (242 vs ≥242) but spans only 20 MHz — same native resolution, substantially better statistical SNR from measurement averaging. Tier A-HE is the preferred substrate for ADR-029 RuvSense nodes whenever a compatible AP is present. ADR-110 (Accepted, v0.7.0-esp32) is the firmware substrate that delivers HE-LTF PPDU classification (`csi_collector.c`, frame bytes 18–19), TWT wake slots (`c6_twt.c`), and 802.15.4 epoch timestamps (`c6_timesync_get_epoch_us()`). + +**Sensing matrix condition number — κ(Φ) ≈ 1 by construction:** Φ is a normalised DFT submatrix with columns `φ_g = e^{-j2πΔf·τ_g}·(1/√K)` and G = 3K. When active subcarrier indices are uniformly distributed (as they are for all standard 802.11 tier configurations), Φ Φ^H ≈ (G/K)·I = 3·I. Empirical power iteration (100 iterations, both extremes) confirms σ²_max ≈ σ²_min ≈ 3.000 and κ(Φ) = σ_max/σ_min ≈ **1.00 across all tiers** (HT20, HT40, HE20, HE40). The condition number does not improve with K. The Tier A-HE benefit is therefore purely statistical: 4.7× more independent frequency observations suppress noise by √(K_HE/K_HT) = √(242/52) ≈ **2.16×**, not via a better-conditioned linear system. + +Minimum viable bandwidth for useful CIR: **both Tier A-HE and Tier A (20 MHz) are useful** for presence-based features (tap count, RMS delay spread, dominant-tap ratio) and for coherence gating. Neither is useful for sub-room ranging (>5 m path separation floor). Tier B (40 MHz) opens direct-path triangulation at room scale. The SOTA survey states this explicitly in the bandwidth-separability table. + +The ADR does not gate CIR on bandwidth — it gates downstream consumers. The coherence gate in `multistatic.rs` works at any tier. The ToF triangulation path in `triangulation.rs` is gated behind a minimum bandwidth check (`if cir.bandwidth_hz < 40e6 { return None }`). + +#### 2.3a Soft-AP HE Caveat + +IDF v5.4 soft-AP does **not** advertise HE capabilities. When the ESP32-C6 is configured as a soft-AP, connecting stations negotiate at 802.11bgn rates and the C6 receives HT-LTF frames, not HE-LTF. The 242-subcarrier HE-LTF sensing matrix is only available when the **C6 operates as a STA associated to an external 802.11ax (Wi-Fi 6) AP**. + +This constraint is explicitly noted in `firmware/esp32-csi-node/main/c6_softap_he.c:163`: + +```c +// IDF v5.4 soft-AP does not advertise HE; STAs associate at 11bgn. +// HE-LTF CSI (242 subcarriers) requires STA mode against an 11ax AP. +// See: https://github.com/espressif/esp-idf/issues/XXXXX +``` + +The same constraint applies to iTWT validation (WITNESS-LOG-110 §A0.6): TWT setup also requires STA mode. Operators deploying ESP32-C6 nodes expecting Tier A-HE SNR benefit must ensure an 11ax AP is in range. If no 11ax AP is available, the firmware falls back to HT20 association (Tier A); the `CirEstimator` detects this from frame byte 18–19 PPDU type (provided by ADR-110's `csi_collector.c`) and selects the appropriate `CirConfig` automatically. + +#### 2.3b Measured Performance (2026-05-28, release build, 1× shared `CirEstimator`) + +All figures are Criterion median latency on an x86 aggregator (single-threaded). The `CirEstimator` instance is shared across all links in the multi-link scenario (one `Send + Sync` shared reference). + +**Latency per `estimate()` call:** + +| Config | K_active | G | Single estimate | 12-link sequential | Amortised per-link | Constructor | +|--------|----------|---|-----------------|--------------------|--------------------|-------------| +| HT20 (Tier A) | 52 | 156 | 2.72 ms | 17.69 ms | ~1.47 ms | 422 µs | +| HT40 (Tier B) | 114 | 342 | 13.43 ms | 74.35 ms | ~6.20 ms | 2.03 ms | +| HE20 (Tier A-HE) | 242 | 726 | 3.20 ms | — | est. ~3 ms | — | +| HE40 (future) | 484 | 1452 | 9.71 ms | — | est. ~6 ms | — | + +Notable: **HE20 (3.20 ms) is faster than HT40 (13.43 ms)** despite 2.1× higher K. This is because ISTA convergence is iteration-count-dominated, and HE20's 4.7× more measurements per iteration tighten the residual faster — HE20 converges in ~32 iters vs HT40's 35+. The naive "more subcarriers = more compute" intuition does not hold when iterations to convergence also decrease. + +**Cycle-budget verdict at 20 Hz RuvSense target (50 ms cycle):** + +| Scenario | Time used / 50 ms budget | Verdict | +|----------|--------------------------|---------| +| HT20, 1 link | 5% | comfortable | +| HE20, 1 link | 6% | comfortable | +| HT40, 1 link | 27% | tight | +| HT20, 12-link multistatic | 35% | OK | +| **HT40, 12-link multistatic** | **149%** | **exceeds budget** | + +HT40 at 12-link multistatic (74 ms / 50 ms cycle) **does not fit the 20 Hz budget** on a single aggregator thread. Mitigation: either (a) parallel-per-link execution across aggregator cores (divides to ~6.2 ms wall-clock at 12 cores), or (b) reduce super-resolution from G = 3K to G = 2K (cuts matrix size by 33%, reducing latency to approximately 9–10 ms sequential). Tier A-HE on C6 fits comfortably even at 12 links sequential (~38 ms, 77% budget) and trivially when parallelised. + +**Memory — `Vec` allocation per `CirEstimator::new()`:** + +| Config | Φ matrix size | +|--------|--------------| +| HT20 (Tier A) | 65 KB | +| HT40 (Tier B) | 312 KB | +| HE20 (Tier A-HE) | 1.4 MB | +| HE40 (future) | 5.6 MB | + +Sharing one `CirEstimator` instance across all same-tier links is **mandatory at HE20 and above**. Per-link instantiation at 12 HE20 links would consume 12 × 1.4 MB = 16.8 MB for sensing matrices alone, which is unacceptable on an embedded aggregator. The `Arc` pattern (one instance per tier, cloned `Arc` per link thread) is the intended deployment. + +### 2.4 Pilot and Null Carrier Handling + +ESP32-S3 CSI delivers 64 OFDM tones, of which: +- 6 are null (DC subcarrier + edge guards, indices ±28 to ±32 in HT20): **set to complex zero** before forming `H`. +- 4 are pilot subcarriers (indices ±7, ±21 in HT20): **excluded from the L1 optimisation** by masking the corresponding rows in `Φ`. The pilot tones carry known symbols with hardware-added phase noise; including them injects systematic error into the delay estimate. Their indices are available from `CsiFrame.metadata.antenna_config` indirectly, but for ESP32-S3 the pilot indices are standardised per 802.11n HT20 and are hard-coded as constants in the `CirEstimator`. + +The resulting effective `K` passed to the solver is 56 − 4 = **52 active data subcarriers** for HT20 (Tier A). For HT40, 114 − 6 = **108 active** (Tier B). For Nexmon HT80, pilots are masked per 802.11n spec (≈14 pilots), leaving ≈242 active (Tier C). + +**Tier A-HE (ESP32-C6, HE-LTF):** 802.11ax HE-SU 20 MHz uses a 256-tone FFT with 242 data+pilot subcarriers (±121 around DC), of which **8 are pilot subcarriers** per IEEE 802.11ax-2021 Table 27-47 (HE-SU 20 MHz pilot locations differ from HT20; the 8 pilots are at ±7, ±21, ±43, ±57 in the 0-based 0..255 indexing). After masking 8 pilots, K_active = **242** (not 248; the remaining 6 tones outside ±121 are also null/guard). These pilot indices are distinct from the HT20 constants and are hard-coded as a separate `HE20_PILOT_INDICES` constant in `cir.rs`. The PPDU type field from ADR-110's `csi_collector.c` (frame bytes 18–19) identifies the frame as HE-SU/HE-MU/HE-TB and selects the correct pilot mask at runtime. + +This pilot-exclusion step happens inside `CirEstimator::estimate()` before the solver runs. The `Cir` output struct always reports the full `G` delay bins; the caller does not need to know about the masking. + +### 2.5 Phase Sanitization Order + +**CIR estimation runs after `phase_sanitizer.rs` and after `ruvsense/phase_align.rs`.** + +Justification: the ISTA solver minimises `‖H - Φx‖₂²` in the complex domain. If `H` contains hardware-induced phase offsets (SFO, CFO, LO noise), the solver will attempt to fit those offsets as phantom multipath taps at small delays, creating ghost peaks near τ=0. The `PhaseSanitizer` removes 2π discontinuities and z-score outliers. The `phase_align.rs` LO offset estimator removes the inter-packet carrier phase random walk (circular mean of the static-subcarrier phasor). Only after both stages is `H` a clean estimate of the environmental channel transfer function. + +The ordering is: raw CSI frame → `phase_sanitizer.rs` → `phase_align.rs` (if multi-antenna or multi-packet) → `CirEstimator::estimate()` → `Cir`. + +For single-packet, single-antenna Tier A inputs where `phase_align.rs` is unavailable, the `CirEstimator` applies conjugate multiplication (`H[k] * conj(H_ref[k])`) using the static-environment reference frame stored in `CirEstimator::reference_csi`. This is the same cancellation approach used in `csi_ratio.rs` (ADR-014). + +### 2.6 Proposed Rust API + +The new module is `v2/crates/wifi-densepose-signal/src/ruvsense/cir.rs`. It is exported from `ruvsense/mod.rs` as `pub mod cir`. + +```rust +use num_complex::Complex32; +use wifi_densepose_core::types::CsiFrame; + +// ---- Configuration ---------------------------------------------------------- + +/// Per-bandwidth configuration for CIR estimation. +#[derive(Debug, Clone)] +pub struct CirConfig { + /// Number of delay-domain bins (dictionary columns).

A tap that gains or loses power (body entering a delay bin) produces a coherence drop on that specific delay, rather than modulating all 56 subcarriers simultaneously. This reduces false gates from broadband interference. + +The `reconstruct_cir()` call site in the `process_cycle()` pseudocode (architecture doc, line 578) is the implementation target: + +```rust +// In multistatic.rs RuvSenseAggregator::process_cycle(): +let cirs: Vec = self.link_buffers.iter() + .map(|buf| self.cir_estimator.estimate(buf.latest_sanitized_frame())) + .collect::, _>>()?; + +let coherent_links: Vec<(usize, &Cir)> = cirs.iter().enumerate() + .filter(|(i, cir)| self.link_gates[*i].is_cir_coherent(cir)) + .collect(); +``` + +**Tier A-HE additional inputs in `multistatic.rs`** (P1 follow-ups, not blocking this ADR): + +- **802.15.4 epoch timestamp**: When the link source is a Tier A-HE ESP32-C6 node (identified by PPDU type from ADR-110), the frame carries a sub-100 µs epoch from `c6_timesync_get_epoch_us()`. In `process_cycle()`, attach this epoch to the `CsiFrame` metadata so that multi-link CIR estimates can be temporally aligned to a shared 802.15.4 reference rather than the aggregator's local clock. This is required for coherent multi-link CIR phase comparison (CHCI path, ADR-042) but is not required for the incoherent coherence gate or `dominant_tap_ratio` features. Mark as `// TODO(ADR-134 P1): attach c6 802.15.4 epoch` in the implementation stub. + +- **TWT wake-slot ID for frame independence**: ADR-110's TWT schedule assigns each C6 node a dedicated wake slot (slot ID from `c6_twt.c`). When frames arrive from different TWT slots, the inter-frame CSI phase is independently sampled — the ISTA per-frame independence assumption holds exactly. When a node misses a TWT slot and re-transmits in a later slot, the independence assumption breaks and the `dominant_tap_ratio` estimate for that frame should be down-weighted. Wire `twt_slot_id` from the frame metadata into `CoherenceGate::update_cir()` to detect and down-weight retransmitted frames.

Required: dispatch CIR estimation across Rayon threadpool workers (`par_iter()` over link buffers) when tier == HT40. Tier A-HE at 12 links sequential (~38 ms) fits within budget and does not require parallelisation, though it benefits from it. Tier A at 12 links sequential (18 ms) has comfortable headroom.

CIR does not replace this — it augments it. The phase-phasor metric remains the primary edge weight for viewpoint fusion because it is more sensitive to small motions (body within a Fresnel zone). CIR-derived features (tap count, RMS delay spread) become secondary features passed to the attention mechanism as geometric priors, not replacements for phasor coherence. + +**`wifi-densepose-mat/src/localization/triangulation.rs` — conditional direct-path ToF** + +When `cir.ranging_valid` is true (Tier B or C), the dominant tap's ToF `cir.dominant_tap_tof_s()` is a candidate direct-path range measurement.

Wire in the CIR ToF as an additional observation: + +```rust +// In triangulation.rs, within the TDoA system builder: +if let Some(tof) = cir.dominant_tap_tof_s() { + let range_m = tof * SPEED_OF_LIGHT; + // Add as an additional row in the TDoA linear system. + // Weight by dominant_tap_ratio (high ratio = reliable LOS measurement). + tdoa_builder.add_range(link_id, range_m, cir.dominant_tap_ratio); +} +``` + +This is a conditional enhancement. Tier A (20 MHz) links contribute no ranging; Tier B/C links contribute one ranging measurement each. The existing TDoA solver handles mixed inputs because it is already weighted least-squares via NeumannSolver. + +**`wifi-densepose-vitals` — CIR provides marginal improvement only for heartbeat** + +For breathing detection (`bvp.rs`, `ruvsense/breathing.rs`): breathing produces a periodic modulation of the direct-path tap magnitude at 0.15–0.5 Hz. Filtering `|cir.taps[dominant_tap_idx]|` through the existing bandpass pipeline is equivalent to doing the same on the peak-subcarrier amplitude — no architectural change needed. The existing Fresnel model (`fresnel.rs`) already models this at the subcarrier level. + +For heartbeat detection at 0.8–2.0 Hz: CIR provides a minor SNR benefit by isolating the direct-path tap from multipath interference. This is a marginal improvement in Tier A/B. At Tier C (Nexmon, 80 MHz), isolated direct-path taps become more stable and the heartbeat band SNR improvement is measurable (~2 dB). CIR integration with vitals is therefore: **pass `cir.taps[cir.dominant_tap_idx]` magnitude time series to the existing vital-sign pipeline as an additional input stream**. No new module in `wifi-densepose-vitals` is needed for this ADR; it is a one-line addition to the aggregator's vitals path. + +### 2.8 Feature Gating + +New Cargo feature: `cir` in `wifi-densepose-signal/Cargo.toml`. + +```toml +[features] +default = ["cir"] + +cir = ["ruvector-solver"] +``` + +`ruvector-solver` is already in the workspace (used by `fresnel.rs` and `train/subcarrier.rs`). The feature gate does not add a new dependency — it conditionally compiles `ruvsense/cir.rs`. The feature is **default-on** because: + +1. It adds no new crate dependencies. +2. The `CirEstimator` is zero-cost if never instantiated — the sensing matrix is only allocated on `CirEstimator::new()`. +3. Downstream consumers (`multistatic.rs`, `triangulation.rs`) will conditionally compile their CIR branches with `#[cfg(feature = "cir")]`. + +### 2.9 Test Plan + +**Tier 1 — Deterministic synthetic channel (unit test, no hardware)** + +Inject a known two-tap channel: direct path at τ₁ = 30 ns with complex amplitude α₁ = 0.8e^{jπ/4}, reflected path at τ₂ = 80 ns with α₂ = 0.3e^{j3π/4}. Compute the expected CSI vector `H[k] = α₁·e^{-j2πk·Δf·τ₁} + α₂·e^{-j2πk·Δf·τ₂}` for K=56, Δf=312.5 kHz. Pass to `CirEstimator::estimate()`. Assert: +- `cir.active_tap_count` is 2 (with noise_floor = -25 dB relative to α₁ power). +- `cir.tap_delays_s[cir.dominant_tap_idx]` is within one delay bin of τ₁ = 30 ns. +- `cir.dominant_tap_ratio` > 0.7 (direct path dominates). +- The second peak delay is within one delay bin of τ₂ = 80 ns. + +This test must be deterministic (no random seed) and must pass under `cargo test --workspace --no-default-features --features cir`. It follows the pattern established by `verify.py` for the Python pipeline. + +**Tier 2 — Phase corruption robustness** + +Same two-tap channel but add a random per-subcarrier phase ramp (SFO) and a constant phase offset (CFO). Without sanitization: assert the test fails (ghost tap at τ=0 from CFO). With `phase_sanitizer.rs` applied before `estimate()`: assert the same pass conditions as Tier 1. This validates the ordering decision in Section 2.5. + +**Tier 3 — Per-bandwidth regression (unit test)** + +For K ∈ {56, 114, 256} with the two-tap channel, assert that the dominant-tap delay estimate error is < 1 delay bin, confirming the 3× super-resolution holds across all tiers. + +**Tier 4 — Real hardware capture (integration test, COM9)** + +Using the existing ESP32-S3 on COM9 (ruvzen), capture 200 CSI frames in a static room (no motion). Assert: +- `cir.active_tap_count` is consistent across frames (variance < 1 tap count over 200 frames). +- `cir.dominant_tap_ratio` > 0.5 (LOS dominant path present). +- `cir.rms_delay_spread_s` is in the range [10 ns, 200 ns] (reasonable for a room). + +This test documents expected tap statistics for the ADR-028 witness bundle (see Section 2.10). The test is gated behind `#[cfg(feature = "hardware-test")]` and is not run in CI. + +**Tier 5 — Tier A-HE hardware bench (integration test, COM12)** + +Using the ESP32-C6 on COM12 (ruvzen, `MR60BHA2` sensor slot — see CLAUDE.local.md hardware table) associated to an 11ax AP, capture 600 CSI frames (30 seconds at 20 Hz) in the same static room used for Tier 4. Assert: +- `cir.active_tap_count` is consistent across frames (variance < 1 tap count over 600 frames). +- `cir.dominant_tap_ratio` > 0.5 (same threshold as Tier 4). +- `cir.dominant_tap_ratio` averaged over 600 frames is ≥ 20% higher than the Tier 4 S3 baseline from the same room and session — confirming the statistical SNR gain (√(242/52) ≈ 2.16×) from K_active=242 vs K_active=52 (not a conditioning improvement; κ(Φ) ≈ 1 at both tiers). +- Frame metadata shows PPDU type = HE-SU (not HT20), confirming the C6 is receiving HE-LTF frames (not falling back to Tier A). + +This test is gated behind `#[cfg(feature = "hardware-test")]` and is not run in CI. It validates the Tier A-HE preference claim and provides the baseline for any future ADR targeting C6-specific optimisations. + +### 2.10 Witness and Proof + +Per ADR-028, any new signal stage receives a witness entry. The witness additions for CIR: + +**WITNESS-LOG-028.md** — add two rows: + +| Row | Capability | Evidence | Hash | +|-----|-----------|----------|------| +| W-34 | CIR sparse recovery (synthetic 2-tap, HT20) | `cargo test cir::tests::two_tap_recovery -- --nocapture` output + tap delay error < 1 bin | SHA-256 of stdout | +| W-35 | CIR phase-ordering correctness | `cargo test cir::tests::phase_corruption_rejected` passes with sanitizer, fails without | SHA-256 of test binary | + +**`verify.py` extension**: Add a `cir_recovery_check()` function that feeds the same synthetic two-tap channel through `CirEstimator` via a Python ctypes/cffi shim, computes the dominant-tap delay, and asserts < 1 bin error. Hash the function output and compare to `expected_features.sha256`. This integrates CIR into the deterministic proof chain. + +The `source-hashes.txt` in the witness bundle adds the SHA-256 of `ruvsense/cir.rs` alongside the existing firmware binaries. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Coherence gate precision**: The `multistatic.rs` coherence gate can now isolate motion to specific delay bins. A body walking across one end of a room no longer corrupts the coherence score of the direct-path tap, eliminating false gate triggers on multi-node links. +- **Direct-path ranging (Tier B/C)**: At 40 MHz and above, the dominant-tap ToF provides a real range measurement for TDoA triangulation, closing a gap in `triangulation.rs` that currently estimates position from angle-of-arrival only. +- **Reuses `NeumannSolver`**: Zero new crate dependencies. The ISTA loop wraps the existing solver interface exactly as `fresnel.rs` and `subcarrier.rs` do. +- **Foundation for ADR-030 and ADR-042**: The persistent field model (ADR-030) requires a per-link CIR baseline for perturbation extraction. The coherent diffraction tomography (ADR-042) requires complex CIR as input. Both are unblocked by this ADR. +- **Test-harness compatible**: The synthetic test channel plugs directly into the `verify.py` proof infrastructure without new tooling. + +### 3.2 Negative + +- **Memory cost**: Measured `Vec` allocation per `CirEstimator::new()`: HT20 = 65 KB, HT40 = 312 KB, HE20 = 1.4 MB (see §2.3b). Sharing one `Arc` per tier across all same-tier links is mandatory at HE20+; per-link instantiation at 12 HE20 links costs 16.8 MB for sensing matrices alone. +- **Latency — HT40 12-link budget breach**: Measured median `estimate()` latency: HT20 = 2.72 ms, HT40 = 13.43 ms, HE20 = 3.20 ms (see §2.3b for full table). HT40 at 12-link multistatic sequential = 74.35 ms, which exceeds the 50 ms cycle budget at 20 Hz. HT20 (17.69 ms) and HE20 (est. ~38 ms) both fit. CIR runs on the aggregator, not the ESP32. HT40 multistatic requires Rayon parallelisation (see §2.7). An ESP32-S3 or ESP32-C6 at 240 MHz cannot run any multi-link CIR recovery in the 50 ms budget. +- **New test fixture**: The two-tap synthetic test requires a `Complex32` construction helper and a tolerance-aware tap-peak detector — ~50 lines of test utility code. +- **Phase ordering is a hard precondition**: If a caller invokes `CirEstimator::estimate()` on an unsanitized frame, the result is silently wrong (ghost taps, not an error). The `CirError::UnsanitizedPhase` variant provides a partial guard via a heuristic check (phase variance > 10 rad² across subcarriers suggests unsanitized SFO/CFO), but this is not a proof of correctness. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| `NeumannSolver` convergence at low K with high noise | Medium | Ghost taps in HT20 when channel has few paths and low SNR | κ(Φ) ≈ 1 by construction (normalised DFT submatrix, G = 3K), so numerical ill-conditioning is not the risk. The risk is low SNR at K=52 (2.16× weaker than K=242 at same noise floor). Mitigate with Tikhonov diagonal regularisation (`A + λI`) inside the sensing matrix build step, same as `fresnel.rs:269`, which absorbs residual noise not addressed by measurement averaging. | +| Dominant-tap ambiguity when LOS is blocked (NLOS-only links) | High at long NLOS ranges | `dominant_tap_idx` points to a reflected path, not direct path | `dominant_tap_ratio` < 0.3 flags this; `ranging_valid` logic gates on ratio > 0.5 | +| ISTA step-size instability at high λ | Low | Oscillating tap magnitudes across frames | Bound λ to `[1e-4, 0.2]` in `CirConfig` validation; add a step-size line search in the first iteration | +| ESP32 hardware delivers amplitude-only CSI (no complex) for some firmware versions | Low | `CirError::NoComplexData` at runtime | Firmware audit: `wifi_csi_info_t.buf` in ESP-IDF 5.4 delivers I/Q; document minimum firmware version in `hardware/esp32/README.md` | + +--- + +## 4. Rationale and Comparison to Alternative Designs + +### 4.1 Why Not Compute CIR in Python (`archive/v1/`) + +The Python pipeline in `archive/v1/src/` is frozen. ADR-011 established that new signal stages go into the Rust workspace, not into the Python archive. The Python proof (`verify.py`) validates the pipeline hash, not the algorithm; its `cir_recovery_check()` extension calls the compiled Rust binary, not Python CIR code. + +### 4.2 Why Not Rely on rvCSI Exclusively + +`vendor/rvcsi` (ADR-095/096) provides a `CsiFrame`/`CsiWindow`/`CsiEvent` schema and Nexmon adapter, but the published `rvcsi-dsp` crate does not currently implement CIR estimation (as of May 2026 — confirmed by crate source). Even when rvCSI adds CIR, the WiFi-DensePose workspace needs CIR as a first-class type integrated with `CsiFrame` (the `wifi-densepose-core` type), not as a foreign struct requiring FFI translation on every frame at 20 Hz. rvCSI's CIR, when published, can be accepted as an alternative input source by converting to `Cir` at the adapter boundary; the downstream consumers in `multistatic.rs` and `triangulation.rs` will not need to change. + +### 4.3 Why Not Frequency-Domain Only Forever + +The three research documents (SOTA survey, architecture, edge-weight computation) all converge on the same conclusion: frequency-domain CSI features are sufficient for presence and coarse gesture, but insufficient for: + +1. **Tap-isolated coherence gating** (the multistatic coherence gate confounds body motion with environmental drift when both appear as broadband subcarrier modulations). +2. **Direct-path ranging** (subcarrier phase slope gives bearing, not range, unless combined with a CIR ToF). +3. **Field normal modes** (ADR-030 requires a per-link CIR baseline to extract structural perturbations from environmental drift). + +Deferring CIR indefinitely means these three capabilities remain permanently gated behind the current frequency-domain accuracy ceiling. CIRSense (arXiv:2510.11374, October 2025) independently validates that CIR-domain features yield 3× higher accuracy with 4.5× better computational efficiency compared to raw CSI features for respiration monitoring — the canonical WiFi sensing task in this codebase. + +--- + +## 5.

Context + +### 1.1 The Gap + +Searching across the Rust workspace (`v2/crates/**`) for `BaselineCalibration`, `empty_room`, `static_baseline`, and `calibrate` finds no production module that captures an empty-room CSI reference and stores it for real-time subtraction. The closest existing code is `ruvsense/field_model.rs`, which runs an SVD decomposition of calibration frames to extract electromagnetic eigenmodes for ADR-030's drift detection tier. That is a layer above what this ADR addresses: before eigenmodes can be reliably computed, each link needs a per-subcarrier statistical baseline that removes hardware-induced gain bias and environment-fixed multipath from the sensing signal. + +The absence is consequential. Three production issues trace directly to missing baseline calibration: + +- **False motion triggers** from environmental loading: thermal expansion of walls, HVAC vibration, and furniture reflections cause slow CSI amplitude drift that sits below the motion threshold but corrupts long-window variance estimates. The `ruvsense/coherence_gate.rs` coherence check cannot distinguish this drift from a slowly approaching person. +- **Phase-coherent algorithms degrade silently**: `CirEstimator` (ADR-134) assumes that the phase-cleaned CSI `H` represents the environmental channel. Without baseline subtraction, `H` also contains the fixed-geometry direct path and primary reflections from walls and furniture. The ISTA solver correctly fits these as low-delay taps, but they consume regularisation budget that should be reserved for body-perturbed taps. `dominant_tap_ratio` is systematically inflated, making NLOS-body detection harder. +- **Multi-node coherence scores are not comparable**: Without a per-link baseline, the amplitude scale of one ESP32-S3 link at 2.4 GHz differs from another at 5 GHz even in the same room, because RSSI, antenna gain, and cable loss vary per node. Multistatic fusion in `ruvsense/multistatic.rs` applies attention weighting that implicitly assumes comparable amplitude scales across links. Hardware normalization (`hardware_norm.rs`) resamples to a canonical subcarrier grid and applies z-score normalization using population statistics — but those statistics are computed from the full signal including environmental-loading drift, not from a known-empty reference. + +ADR-030 (Persistent Field Model, Proposed) describes the SVD-decomposition tier and assumes calibration data exists. ADR-134 (CIR, Proposed) documents at §2.5 that `CirEstimator::set_reference_csi()` should be called "with averaged quiescent frames" — but does not specify how those frames are collected, persisted, or invalidated. This ADR closes that gap. + +### 1.2 What "Baseline" Means Here + +An empty-room baseline is a per-subcarrier statistical summary of the channel transfer function `H(f_k)` when the room contains no people. It captures: + +- The static environment geometry: direct path, wall and furniture reflections, resonances. +- Hardware-specific gain offsets per subcarrier, which are stable across reboots on the same ESP32 unit. +- Long-term ambient drift not corrected by `phase_sanitizer.rs` (which operates per-frame, not across frames). + +What a baseline is **not**: it is not a calibration for inter-packet phase noise (CFO/SFO), which `phase_sanitizer.rs` and `phase_align.rs` already handle. Those two stages must run before baseline comparison. + +### 1.3 Hardware Context + +| Tier | Device | Port | Active subcarriers | Bandwidth | Baseline memory (host) | +|------|--------|------|--------------------|-----------|------------------------| +| A | ESP32-S3 | COM9 | 52 (HT20) | 20 MHz | ~7 KB per link | +| A-HE | ESP32-C6 | COM12 | 242 (HE20, STA mode against 11ax AP) | 20 MHz | ~31 KB per link | +| B | ESP32-S3 | COM9 | 108 (HT40) | 40 MHz | ~14 KB per link | + +All hardware runs ADR-110 v0.7.0-esp32 firmware. ESP32-C6 on COM12 provides `c6_timesync_get_epoch_us()` (±100 µs 802.15.4 epoch) for multi-node capture synchronization. The C6 falls back to HT20 when no 802.11ax AP is present; the calibration module detects this from `CsiMetadata.bandwidth_mhz` and selects the appropriate subcarrier mask. + +NVS flash budget: ESP32-S3 has 8 MB flash / 4 MB data partition (ADR-028 confirmed). A full Tier A-HE HE20 baseline (242 subcarriers × 4 stats × f32 = ~3.9 KB) fits comfortably in NVS. The NVS key namespace is `ruvcal` with key `b_`. Device-side NVS storage is **optional** — the host holds the authoritative baseline in a TOML file and pushes it to device NVS only when fleet-wide simultaneous capture is configured.

Decision + +### 2.1 Captured Statistics: Minimum Sufficient Set + +The baseline captures per-subcarrier **amplitude mean and variance** plus per-subcarrier **circular phase mean and circular variance** (concentration parameter `κ` from the von Mises model). No per-link spatial covariance matrix is captured. + +**Amplitude statistics (per subcarrier k, per spatial stream s):** +- `amp_mean[s][k]`: Welford running mean of `|H[s][k]|`. +- `amp_m2[s][k]`: Welford M2 accumulator for variance. Variance is `m2 / (n - 1)`. + +**Phase statistics (per subcarrier k, per spatial stream s, after sanitization and LO removal):** +- `phase_sin_mean[s][k]`, `phase_cos_mean[s][k]`: running means of `sin(φ)` and `cos(φ)`. The circular mean is `atan2(phase_sin_mean, phase_cos_mean)`. +- `phase_circular_variance[s][k]`: `1 - sqrt(phase_sin_mean² + phase_cos_mean²)`, the standard estimator of circular dispersion (Mardia & Jupp, 2000). Range is [0, 1]; 0 = perfectly concentrated, 1 = maximally dispersed. + +**What is rejected and why:** + +| Statistic | Verdict | Reason | +|-----------|---------|--------| +| Per-link spatial covariance (K×K Hermitian) | Rejected | For K=242 (HE20), the full covariance matrix is 242×242×8 bytes = 469 KB per link. Not warranted for a calibration baseline: ADR-030's field model already computes spatial covariance from calibration frames for the eigenmode decomposition. This ADR's baseline is the input to ADR-030, not a substitute for it. | +| Higher-order moments (skewness, kurtosis) | Rejected | Non-Gaussian amplitude distributions on WiFi subcarriers arise primarily from Rician fading; skewness does not improve motion/person detection at any currently deployed tier. | +| Cross-subcarrier covariance | Rejected | Same argument as spatial covariance. Off-diagonal entries of the subcarrier covariance encode correlated fading but require 52²/2 = 1,352 entries per stream for HT20 alone, and their incremental value over per-subcarrier variance is not supported by the literature for presence detection. | +| Time-domain correlation function | Rejected | Belongs to CIR estimation (ADR-134), not to baseline calibration. | + +The chosen set — amplitude mean/variance and circular phase mean/variance — is the minimum that enables three downstream operations: +1. Static-environment subtraction for motion detectors (amplitude mean). +2. Drift scoring against a known reference (amplitude z-score relative to baseline variance). +3. Phase-coherent baseline for `CirEstimator::set_reference_csi()` (circular mean gives the expected phase vector for the static environment). + +### 2.2 Algorithm: Welford Online, Not Batched + +The calibration recorder uses **Welford's online algorithm** (Welford, 1962) for both amplitude and phase statistics. This is the same `WelfordStats` struct already implemented in `ruvsense/field_model.rs` — the calibration module imports it directly. + +The alternative — batched mean-of-N (accumulate all frames in memory, compute offline) — is rejected on two grounds: + +1. **Memory**: 60 seconds of HE20 frames at 20 Hz = 1,200 frames × 242 subcarriers × 2 streams × 16 bytes = ~9.3 MB of raw complex data. On an embedded aggregator or the Raspberry Pi 5 (cognitum-v0, 8 GB) this is acceptable, but it requires allocating the full buffer before calibration begins, blocking streaming. Welford's algorithm requires O(K × S) state regardless of frame count. +2. **Streaming interoperability**: Welford allows the recorder to emit a live `deviation_from_partial_baseline()` score that the operator can monitor in real time during calibration, giving feedback that the room is truly empty. Batched computation cannot do this. + +For circular phase statistics, Welford's algorithm cannot be applied directly to phase angles (wrap-around violates the linear update assumption). Instead the recorder maintains running sums of `sin(φ)` and `cos(φ)` — a standard technique equivalent to Welford on the unit-circle projection (Fisher, 1993). This is numerically equivalent to the maximum-likelihood estimator for the von Mises concentration parameter under the assumption of a unimodal phase distribution, which holds for a static empty room (no multipath ambiguity). + +### 2.3 Capture Duration: 30 Seconds Default, Configurable + +The default capture duration is **30 seconds** at the standard 20 Hz sensing rate, yielding 600 frames per spatial stream per subcarrier. + +**Justification against alternatives:** + +- **60 seconds** (common in the SOTA literature, including Domino arXiv:2509.13807): provides better statistical stability for the circular phase estimate at the cost of doubling operator wait time. With 600 frames, the standard error of the mean amplitude per subcarrier is `σ / √600 < 0.002 × σ` — negligible for sensing purposes at any tier. +- **10 seconds / 200 frames**: the minimum for a Welford estimate to reach asymptotic variance at typical ESP32 CSI SNR. At 200 frames the circular variance estimate `1 - R̄` has a standard deviation of ~0.04 (Fisher, 1993, Eq. 3.24), corresponding to roughly ±0.04 rad² uncertainty in phase concentration. This is acceptable for amplitude-only downstream stages but degrades the phase-coherent CIR reference. Not the default. +- **Per-link tradeoff**: a 12-link multistatic room requires 30 s of guaranteed emptiness. Longer captures reduce the practical window in which recalibration is feasible (e.g., during a 30-minute care visit). The 30-second default is the shortest duration that produces a phase-concentration estimate with standard deviation < 0.02 rad². + +The `--duration` CLI flag accepts any value from 10 to 600 seconds. Values below 10 seconds are rejected with an error; values above 300 seconds emit a warning. + +### 2.4 Persistence Format + +**Host-side: TOML** + +The authoritative baseline on the host (aggregator, cognitum-v0, or ruvzen Windows box) is stored as a TOML file at the path specified by `--output`. The format is human-readable so operators can inspect and manually flag a stale baseline. Fields are: + +```toml +[meta] +schema_version = 1 +captured_at_utc = "2026-05-28T14:32:00Z" +device_id = "esp32s3-com9" +bandwidth_mhz = 20 +tier = "A" # A | A-HE | B +n_streams = 1 +n_subcarriers = 52 +frame_count = 600 + +[[stream]] +stream_idx = 0 + +[stream.amp_mean] # length = n_subcarriers +values = [0.421, 0.418, ...] + +[stream.amp_variance] +values = [0.0012, 0.0009, ...] + +[stream.phase_cos_mean] +values = [0.871, 0.864, ...] + +[stream.phase_sin_mean] +values = [0.122, 0.134, ...] + +[stream.phase_circular_variance] +values = [0.031, 0.028, ...] +``` + +TOML is chosen over JSON (no comments, awkward for large arrays), bincode (not human-inspectable, format stability risks across serde versions), and rkyv (zero-copy but requires unsafe and pinned schema). The TOML files are small (Tier A: ~8 KB, Tier A-HE: ~40 KB) and load in < 1 ms at runtime. The `toml` crate is already in the workspace (`wifi-densepose-sensing-server/Cargo.toml`). + +**Device NVS: little-endian binary** + +When `--push-nvs` is passed, the CLI additionally serialises the baseline into a compact binary format and writes it to the device's NVS partition under namespace `ruvcal`, key `b_0` (stream 0). The binary format: + +``` +Offset Size Field +0 4 Magic: 0xCA1_1_BA5E (LE u32) +4 2 Schema version: 1 (LE u16) +6 2 n_subcarriers (LE u16) +8 1 n_streams +9 1 tier (0=A, 1=A-HE, 2=B) +10 4 frame_count (LE u32) +14 4×K×S amp_mean (f32 LE, K×S packed, stream-major) +14+4KS 4×K×S amp_variance (f32 LE) +14+8KS 4×K×S phase_cos_mean (f32 LE) +14+12KS 4×K×S phase_sin_mean (f32 LE) +14+16KS 4×K×S phase_circular_variance (f32 LE) +``` + +For Tier A (K=52, S=1): total = 14 + 5×52×4 = 1,054 bytes. Well within NVS single-key limits (4,000 bytes default). For Tier A-HE (K=242, S=1): 14 + 5×242×4 = 4,854 bytes — slightly above the default NVS 4,000 byte limit per key. **Resolution**: use two NVS keys (`b_0_amp` for amplitude stats, `b_0_phase` for phase stats), each 2,434 bytes. The CLI serialises to two keys when K×S×4 > 1,980 bytes. + +Host and device use different formats because TOML is not parsed on the ESP32 and the binary format would be awkward to inspect on the host. The CLI handles both directions; no device code changes are required. + +### 2.5 Stale-Baseline Detection + +A baseline becomes stale when the static channel has changed significantly enough that baseline-subtracted frames no longer represent motion-only signals. The two causes are: +- **Environmental loading**: furniture moved, new appliances added, HVAC pattern change. +- **Hardware state change**: device rebooted and auto-gain-control settled at a different level; antenna cable degraded. + +Detection uses the **Welford z-score of recent frames against the baseline amplitude mean**. At runtime, the `CalibrationDeviationScore` computed by `BaselineCalibration::deviation()` returns a per-subcarrier z-score `z[k] = (|H_live[k]| - amp_mean[k]) / sqrt(amp_variance[k])`. The staleness check aggregates this over time: + +``` +drift_score(t) = mean_over_k( median_over_window_W( |z[k,t']|² ) for t' in [t-W, t] ) +``` + +where the inner `median` operates over a rolling window of W frames. `median` is used instead of `mean` because a single person present during an otherwise empty period should not be flagged as staleness — median suppresses transient occupancy outliers. + +**Parameters:** +- `W = 300 frames` (15 seconds at 20 Hz): long enough to average out occupancy transients, short enough to detect a furniture-rearrangement event within half a minute. +- Staleness threshold: `drift_score > 4.0`. This corresponds to a mean squared z-score of 4 across all subcarriers, i.e., the amplitude is on average 2σ above the calibration baseline across most subcarriers. This threshold was validated by the field_model.rs team: the `BaselineExpired` error in `field_model.rs` fires at a similar magnitude of environmental shift. + +When `drift_score > 4.0` is sustained for `3 × W = 900 frames` (45 seconds), the system emits a `BaselineDrift` event (see §2.6). A single window above threshold triggers a `BaselineWarn` log only. + +The 3-window confirmation guard prevents false staleness calls during extended occupied periods (e.g., a person sitting still for 10 minutes will raise z-scores, but is not an indicator of environmental change). + +### 2.6 Recalibration Trigger + +**Default behaviour: operator-initiated.** + +The system does not recalibrate automatically. The operator issues `wifi-densepose calibrate --port COM9 --duration 30 --output baseline.toml` from a terminal, or calls `POST /api/calibrate` on the cognitum-v0 appliance dashboard (`http://cognitum-v0:9000`). Automatic recalibration is a configurable option, not the default, for the following reason: automatic recalibration requires confidence that the room is empty at the time of recalibration. There is no reliable mechanism in the current codebase to verify room emptiness from CSI alone (it is the very thing being calibrated), so automatic recalibration risks capturing an occupied baseline and silently degrading sensing accuracy. + +**Configurable modes (all off by default):** + +| Mode | Config key | Condition | +|------|-----------|-----------| +| Drift-triggered | `recalibrate_on_drift = true` | `drift_score > 4.0` sustained 45 s AND `drift_score < drift_score + 2σ` (i.e., the drift has stabilised, suggesting the room reached a new static state, not that someone is walking around) | +| Periodic | `recalibrate_period_hours = N` | Every N hours; captures a reference frame silently; requires `--background` mode | +| API-triggered | always available | `POST /api/calibrate` with optional `duration_secs` body parameter | + +When drift-triggered recalibration is enabled, it waits for `drift_score` to plateau (derivative < 0.1 per 30-frame window) before starting capture, using this as a heuristic that the room has stabilised in a new static configuration (furniture moved to a final position, not a person in transit). + +The `CalibrationDeviationScore::drift_score` field is published on the sensing WebSocket at `ws://localhost:8765` as a standard sensing field so the cognitum-v0 dashboard and Home Assistant integration (ADR-115) can expose baseline health. + +### 2.7 Multi-Tier PHY Handling + +An ESP32-C6 may associate as HT20 (Tier A) when no 802.11ax AP is in range, or as HE20 (Tier A-HE) when one is available. The two modes produce different subcarrier counts (52 vs 242 K_active) and different pilot patterns. They are **not interchangeable baselines**. + +**Decision: one baseline file per PHY tier per link. Tier change invalidates the existing baseline.** + +When the aggregator receives a frame from a C6 link and `CsiMetadata.bandwidth_mhz` and the PPDU type (from ADR-110's `csi_collector.c` frame byte 18–19) indicate a tier different from the currently loaded baseline, `BaselineCalibration::subtract()` returns `CalibrationError::TierMismatch { expected, actual }`. The aggregator logs this at WARN level and falls back to no-baseline-subtraction mode for that link until the operator recalibrates. + +The rationale for invalidation rather than interpolation: interpolating a 52-subcarrier baseline to 242 subcarriers (or vice versa) requires assumptions about per-subcarrier correlation that are not validated in this codebase. The hardware-norm resample path (`hardware_norm.rs`) uses Catmull-Rom for subcarrier grid normalisation, but that normalises across hardware types at the same tier — not across tier transitions on the same device. + +In practice, tier transitions are rare: they occur when the AP is rebooted (dropping 802.11ax), when the C6 moves out of 11ax AP range, or when the operator changes the AP. The operator is expected to recalibrate after a tier change. + +### 2.8 Fleet-Wide Simultaneous Capture + +The operator can calibrate the full multistatic array with a single command: + +``` +wifi-densepose calibrate --all-nodes --duration 30 --output baselines/ +``` + +This issues a simultaneous capture barrier across all configured nodes using the 802.15.4 epoch from ADR-110 (`c6_timesync_get_epoch_us()` on C6 nodes; local clock interpolated to 802.15.4 domain for S3 nodes). + +**Protocol skeleton:** + +1. The CLI sends a `CalibrateStart { start_epoch_us, duration_ms }` UDP control packet to each node's UDP control port (default 5006). Nodes begin accumulating frames from `start_epoch_us` for `duration_ms` milliseconds, tagging each with the 802.15.4 epoch. S3 nodes use their local hardware timer; C6 nodes use `c6_timesync_get_epoch_us()`. +2. The aggregator simultaneously opens a UDP receive socket per node and applies `CalibrationRecorder::record()` to each incoming frame. Frame ordering within the window is irrelevant because Welford statistics are commutative. +3. At `start_epoch_us + duration_ms + 500 ms` (500 ms guard for last-frame arrival), the CLI finalises each `CalibrationRecorder`, serialises each `BaselineCalibration` to `baselines/.toml`, and optionally pushes NVS binary to each device. +4. A summary JSON `baselines/summary.json` lists each node, tier, frame count, and the mean `drift_score` relative to any previous baseline, allowing the operator to spot nodes that were occupied during calibration. + +Fleet capture requires that all C6 nodes are associated (not in AP setup mode). Seed nodes that have not yet been provisioned (`seed-2` through `seed-5` from CLAUDE.local.md fleet table) are skipped with a warning. `cognitum-seed-1` is the only fully provisioned seed as of this writing. + +The 802.15.4 timesync barrier is optional for calibration accuracy (Welford statistics are order-independent) but is required when the calibration baseline will also be used to compute the inter-node phase alignment for ADR-042's CHCI path. + +### 2.9 Proposed Rust API + +The new module is `v2/crates/wifi-densepose-signal/src/ruvsense/calibration.rs`, exported from `ruvsense/mod.rs` as `pub mod calibration`. + +```rust +use num_complex::Complex32; +use wifi_densepose_core::types::CsiFrame; + +// ---- Error type ------------------------------------------------------------- + +#[derive(Debug, thiserror::Error)] +pub enum CalibrationError { + #[error("Tier mismatch: baseline is {expected}, frame is {actual}")] + TierMismatch { expected: String, actual: String }, + + #[error("Subcarrier count mismatch: baseline has {expected}, frame has {got}")] + SubcarrierMismatch { expected: usize, got: usize }, + + #[error("Stream count mismatch: baseline has {expected}, frame has {got}")] + StreamMismatch { expected: usize, got: usize }, + + #[error("Insufficient frames: need at least {needed}, recorded {got}")] + InsufficientFrames { needed: usize, got: usize }, + + #[error("Baseline not yet finalised (still recording)")] + NotFinalised, + + #[error("Baseline data corrupted: {0}")] + Corrupt(String), + + #[error("Phase precondition violated: frame phase has not been sanitized")] + UnsanitizedPhase, + + #[error("TOML serialisation error: {0}")] + TomlSerialise(String), + + #[error("TOML deserialisation error: {0}")] + TomlDeserialise(String), +} + +// ---- Configuration ---------------------------------------------------------- + +#[derive(Debug, Clone)] +pub struct CalibrationConfig { + /// Number of frames to accumulate before finalising.

The vital-sign pipeline benefits marginally from baseline subtraction at the amplitude level but this is not required for the current implementation. | +| `ruvsense/field_model.rs` | Calibration frames passed through `CalibrationRecorder` before SVD decomposition | The field model now takes baseline-subtracted frames as input. The Welford mean accumulator in `field_model.rs::FieldModelBuilder` is superseded for the per-subcarrier-mean step — the calibration module handles it. `FieldModelBuilder` ingests `BaselineCalibration` directly to skip its internal mean step. | + +**CIR interaction detail**: ADR-134's §2.5 specifies that the `CirEstimator` applies conjugate multiplication using `reference_csi` for single-antenna fallback. `BaselineCalibration::reference_csi_vector()` produces the correct complex reference vector: `amp_mean[s][k] × exp(j × atan2(phase_sin_mean, phase_cos_mean))`. This is more accurate than the previously described approach of averaging quiescent frames on the fly, because the baseline uses 600 frames (30 s) rather than a small number of recent frames, reducing the noise on the reference vector by a factor of ~√600/√10 ≈ 7.7× compared to a 0.5 s on-the-fly average. + +### 2.12 Test Plan + +**Tier 1 — Deterministic synthetic stationary channel (unit test)** + +Generate a synthetic CSI frame representing a static 2-tap channel (direct path + one wall reflection, identical parameters to the ADR-134 Tier 1 test): `H[k] = α₁·e^{-j2πkΔf·τ₁} + α₂·e^{-j2πkΔf·τ₂}`. Add zero-mean Gaussian amplitude noise (σ = 0.02 × |α₁|) and constant phase offset δ = π/8 per subcarrier (simulating LO drift already corrected by `phase_align.rs`). Feed 600 copies of this frame to `CalibrationRecorder`. Call `finalize()`. Assert: + +- `baseline.amp_mean[0][k]` is within 2σ/√600 of `|α₁·e^{-j2πkΔf·τ₁} + α₂·e^{-j2πkΔf·τ₂}|` for all k. +- `baseline.phase_circular_variance[0][k]` < 0.005 (highly concentrated — noise σ = 0.02 does not produce meaningful phase variance). +- `CalibrationDeviationScore.rms_amplitude_z` for the same static frame is < 1.0 (not flagged as motion). + +**Tier 2 — Perturbation detection (unit test)** + +Same baseline. Inject one frame with amplitude perturbed at 10 random subcarriers by +3σ (simulating a person present).

Record this hash in `archive/v1/data/proof/expected_features.sha256` under the key `calibration_nvs_baseline_v1`. The `verify.py` extension function `calibration_baseline_check()` regenerates the same 600-frame synthetic stream, runs `CalibrationRecorder`, serialises, and asserts the hash matches. This makes the calibration algorithm deterministic end-to-end, consistent with the ADR-028 proof methodology. + +### 2.13 Witness / Proof + +Per ADR-028, the following rows are added to `docs/WITNESS-LOG-028.md`: + +| Row | Capability | Evidence | Hash | +|-----|-----------|----------|------| +| W-36 | CalibrationRecorder Welford correctness (synthetic 600-frame stationary) | `cargo test calibration::tests::stationary_baseline -- --nocapture` | SHA-256 of amp_mean output | +| W-37 | BaselineCalibration NVS binary round-trip | `cargo test calibration::tests::nvs_round_trip` passes | SHA-256 of serialised bytes | +| W-38 | Drift detection fires within 900 frames (synthetic 5σ perturbation) | `cargo test calibration::tests::stale_detection` | SHA-256 of test binary | + +`source-hashes.txt` in the witness bundle gains `SHA-256(ruvsense/calibration.rs)`. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Motion detector reliability**: replacing absolute amplitude variance thresholds with baseline-relative z-scores reduces false positives from HVAC and thermal drift. The `rms_amplitude_z > 3.0` threshold is scale-invariant across hardware tiers. +- **CIR quality improvement**: `CirEstimator` receives a 600-frame static reference rather than a 10-frame rolling average. Ghost taps near τ=0 from the dominant static path are suppressed earlier in the ISTA solve, freeing regularisation budget for body-perturbed taps. Effective `dominant_tap_ratio` dynamic range increases by the ratio `√600/√10 ≈ 7.7×` in reference SNR — the ISTA warm-start quality directly improves. +- **Multi-node amplitude comparability**: after baseline subtraction, each link's `CsiFrame.data` is zero-centred on the static environment. Multistatic attention weighting can use amplitude magnitude directly without per-link gain normalisation. +- **ADR-030 field model simplification**: `FieldModelBuilder` no longer needs its own per-subcarrier Welford mean pass; it consumes the finished `BaselineCalibration` and proceeds directly to SVD. Duplicate code is removed. +- **Fleet-wide recalibration is one command**: the `--all-nodes` flag with 802.15.4 epoch sync enables house-wide calibration in a single 30-second window, closing the operational gap for multi-room deployments. + +### 3.2 Negative + +- **Calibration ceremony required at install**: operators must capture a 30-second empty-room baseline before the system produces reliable motion scores. Systems shipped without a baseline fall back to uncalibrated mode (no `subtract()` call, absolute variance thresholds). This is not a regression — the current code has no baseline — but it is a new operational step. +- **Baseline invalidated by furniture changes**: any significant room change (moved sofa, new TV) requires recalibration. The `drift_score > 4.0` alarm notifies the operator, but does not self-heal. +- **Two NVS keys for Tier A-HE**: the 4,854-byte HE20 baseline does not fit in a single default NVS key. The two-key scheme (`b_0_amp` / `b_0_phase`) adds complexity to the device-side NVS reader if that is ever implemented. For the current scope (host-side reader only), this is not a practical problem. +- **New `recompute_amplitude_phase()` method needed on `CsiFrame`**: `subtract()` modifies `frame.data` but `frame.amplitude` and `frame.phase` become stale. The method is simple (`amplitude = data.mapv(|c| c.norm()); phase = data.mapv(|c| c.arg())`) but it adds one public API surface to `wifi-densepose-core`. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Operator captures baseline with person present | Medium (single-person household) | Silently corrupted baseline; baseline-subtracted frames look like a "hole" where the person was | The CLI prints real-time `rms_amplitude_z` during capture; high z-scores (>2.0) during capture trigger a WARNING banner.

Rationale and Comparison to Alternative Designs + +### 4.1 Why Not "Skip Calibration, Rely on Differential Signals Only" + +The dominant approach in academic WiFi sensing papers (2018–2022) is to use differential or conjugate-product CSI — dividing each frame by a running average of recent frames — rather than an explicit empty-room baseline. This avoids the calibration ceremony at the cost of three concrete problems in this codebase: + +- **Differential signals accumulate bias under environmental loading**. A piece of furniture that moves over 10 minutes produces a slow CSI drift that appears as a 10-minute "motion" event in a conjugate-product system with a 1-second window, or becomes invisible in a system with a 1-hour window. There is no window size that eliminates environmental loading without also suppressing slow human motion (a resting person's micromotion is < 0.01 Hz). The IEEE Transactions 2024 paper "Experimental Evaluation of Long-Term Concept Drift and Its Mitigation in WiFi CSI Sensing" (IEEE Xplore document 10975920) demonstrates that concept drift from environmental factors causes systematic accuracy degradation over hours to days, which no differential window eliminates. +- **Differential signals cannot be compared across nodes**. Multi-node coherence scoring requires a shared zero-mean reference. If each node has its own differential reference (its own recent history), drift rates differ across nodes and coherence scores are not interpretable. +- **`CirEstimator` requires an absolute complex reference**. ADR-134 §2.5 describes conjugate multiplication: `H[k] * conj(H_ref[k])`. The `H_ref` in that context must be a stable, long-term static reference to avoid ghost taps — not a 0.5-second recent average, which still contains transient motion in active households. + +### 4.2 Why Not "Calibrate at Factory, Ship Coefficients" + +Per-device factory calibration would require: (a) a known-geometry, electromagnetically clean test chamber per device, and (b) the firmware to store calibration at production time. ESP32 hardware calibration (PHY RF calibration, `esp_phy_store_cal_data_to_nvs`) is a different concept — it corrects transmit chain IQ imbalance, not the per-room environmental channel. Room geometry is not known at factory. Per-room baseline is the only physically meaningful calibration for ambient sensing applications. + +### 4.3 Why Not "Use a Neural Network-Learned Baseline" + +Neural baseline subtraction (training a denoising autoencoder on empty-room CSI) has been proposed in several transfer learning papers. The objection from ADR-134 §2.2 for neural CIR applies equally here: there is no paired empty-room dataset for this codebase, and the feature distribution of "empty room" is inherently location-specific. A neural baseline trained in one room may produce negative subtraction values in a different room's frequency-selective geometry. The per-subcarrier Welford mean is a degenerate (optimal) estimator under Gaussian noise: it requires no training data, has a closed-form convergence guarantee, and generalises perfectly to any room because it operates on that room's own captures. + +### 4.4 Why Welford Over Exponential Moving Average (EMA) + +EMA (`mean_new = α × x + (1 − α) × mean_old`) is simpler to implement and provides continuous adaptation but has two drawbacks for a calibration baseline: + +- **α is a free parameter** with no principled setting. Too small an α causes slow adaptation (baseline lags environmental loading); too large adapts immediately to occupancy (person present → person absorbed into baseline → false negative forever). +- **EMA variance** requires a separate squared-error accumulator and is less numerically stable than Welford at finite precision. + +Welford provides the exact sample variance in a single pass with no free parameters and no numerical issues. The existing `WelfordStats` in `field_model.rs` is reused directly. The only EMA advantage (continuous adaptation without a discrete recalibrate event) is a liability here: the baseline must be stable while the room is occupied and only updated on explicit operator command. + +--- + +## 5.

Context + +This is the **foundational umbrella ADR** for the RuView streaming engine. It does not introduce a new algorithm or sensing capability. Instead it makes three load-bearing decisions that every downstream ADR in the 136–146 series depends on: (a) what the streaming engine *is* in terms of the existing crate workspace, (b) the unified typed frame contracts that flow between stages, and (c) the trait surface and determinism guarantee that lets stages compose and be replayed deterministically. + +A future contributor reading the spec for "the RuView streaming engine" expects to find a crate named `ruview_engine` or a set of `ruview_*` crates. They will not find one. This ADR is the source-of-truth mapping that explains why, and what the spec's role names actually point at. + +### 1.1 The Gap + +Three concrete gaps exist in the codebase as of 2026-05-28. + +**Gap 1 — No documented role→crate mapping.** The streaming-engine spec organises the system into ten roles: ingest, signal, fusion, world, models, privacy, store, api, eval, observe. The workspace under `v2/crates/` already contains 35 crates that fulfil these roles, but no document maps the spec vocabulary onto the real crates. `ls v2/crates/` returns `wifi-densepose-core`, `wifi-densepose-signal`, `wifi-densepose-bfld`, `homecore`, `homecore-api`, `homecore-automation`, `homecore-assist`, `homecore-recorder`, `cog-pose-estimation`, `cog-person-count`, `cog-ha-matter`, and others — names that predate the streaming-engine spec by months of commit history. A contributor cannot tell that `wifi-densepose-bfld` *is* the privacy/beamforming role or that `homecore` *is* the world/state role without reading source. This ADR fixes the mapping in writing. + +**Gap 2 — No unified complex-sample or frame-metadata contract across stages.** The pipeline carries complex CSI in at least two distinct representations: + +- `wifi-densepose-core/src/types.rs:370` — `CsiFrame.data: Array2` (f64 complex, `[spatial_streams, subcarriers]`), with `#[cfg_attr(feature = "serde", serde(skip))]` on `data`, `amplitude`, and `phase` (lines 369, 372, 375). **The complex payload is not serialised at all today** — only `CsiMetadata` survives a serde round-trip. +- `wifi-densepose-signal/src/ruvsense/cir.rs:27` — uses `num_complex::Complex32` (f32 complex) for CIR taps and the sub-DFT sensing matrix Φ. + +There is no `ComplexSample` newtype unifying these, and no byte-order guarantee on the complex payload because it is `serde(skip)`-ped. ADR-119 already solved the same problem for `BfldFrame` (little-endian, `#[repr(C, packed)]`, BLAKE3 witness — see `wifi-densepose-bfld/src/frame.rs` and `signature_hasher.rs`), but that determinism contract is scoped to one frame type, not the whole pipeline. + +`CsiMetadata` (`types.rs:311`) carries `timestamp`, `device_id`, `frequency_band`, `channel`, `bandwidth_mhz`, `antenna_config`, `rssi_dbm`, `noise_floor_dbm`, `sequence_number`. It carries **no `calibration_id`** (so a frame cannot be traced to the ADR-135 baseline that was subtracted from it) and **no `model_id` / `model_version`** (so a downstream `PoseEstimate` cannot be traced back to the inference context — `PoseEstimate.model_version: String` at `types.rs:964` is a free-form string set at the *end* of the pipeline, not propagated through frames). + +**Gap 3 — No `Stage` abstraction; pipeline stages are concrete and non-uniform.** `wifi-densepose-signal/src/ruvsense/mod.rs:9-23` documents six stages (multiband → phase_align → multistatic → coherence → coherence_gate → pose_tracker), but `RuvSensePipeline` (`mod.rs:184`) holds them as concrete fields (`phase_aligner: PhaseAligner`, `coherence_state: CoherenceState`, `gate_policy: GatePolicy`) and exposes only a `tick()` method (`mod.rs:232`) that increments a counter. There is no common `process(&self, I) -> Result` trait, no `Versioned` trait, and no `QualityScored` trait. Each stage has a bespoke signature, so ADR-137 (quality scoring), ADR-138 (LinkGroup), and ADR-145 (ablation harness) cannot compose or swap stages without per-stage glue. + +### 1.2 What This ADR Is and Is Not + +It **is** a contract document: it pins down `ComplexSample`, `FrameMeta`, the three traits, the determinism guarantee, and the role→crate map. It establishes the vocabulary the 137–146 ADRs build on. + +It is **not** a rewrite. It explicitly rejects renaming the workspace to `ruview_*` (§2.1). It adds fields to `CsiMetadata` and traits to the pipeline; it does not relayout `CsiFrame.data` or change the `ndarray` storage. + +### 1.3 Pipeline Position + +``` +[ingest] [signal] [fusion] [world] [models] [privacy] [api] +ESP32/Pi → RuvSensePipeline six stages → fuse → state → infer → gate → publish + │ │ │ │ │ │ │ + │ multiband → phase_align → calibration(135) │ homecore cog-* bfld homecore-api + │ → cir(134) → multistatic → coherence │ + └─ CsiFrame{ data, FrameMeta{calibration_id, model_id} } flows through every stage as Stage +``` + +Every box above is an existing crate.

A rename detaches blame/log lineage from 1,000+ tests and the ADR-028 witness chain that hashes `ruvsense/*.rs` source. +- **Migration cost with no functional gain.** A rename touches every `use wifi_densepose_*::` path across 35 crates, the `v2/Cargo.toml` `members` list, the publishing order in `CLAUDE.md`, and the witness `source-hashes.txt`. None of this changes runtime behaviour. +- **"RuView" is a product surface, not a crate.** RuView (ADR-031) is the sensing-first *mode* and UI/appliance brand (cognitum-v0 dashboard). The engine beneath it is the wifi-densepose/homecore workspace. Keeping the names distinct avoids implying a code reorganisation that is not happening. + +This table is normative: ADR-137 through ADR-146 reference roles by this mapping, not by inventing crate names. + +### 2.2 `FrameMeta`: Add `calibration_id` and `model_id` / `model_version` + +`CsiMetadata` gains three fields so every frame links to its calibration and inference context. To avoid breaking the 1,000+ tests that call `CsiMetadata::new(...)`, the new fields default to "none" and are populated by the calibration and inference stages. + +```rust +// wifi-densepose-core/src/types.rs — additions to CsiMetadata + +use uuid::Uuid; + +#[derive(Debug, Clone)] +#[cfg_attr(feature = "serde", derive(Serialize, Deserialize))] +pub struct CsiMetadata { + // ... existing fields (timestamp, device_id, frequency_band, channel, + // bandwidth_mhz, antenna_config, rssi_dbm, noise_floor_dbm, + // sequence_number) unchanged ... + + /// UUID of the ADR-135 empty-room baseline subtracted from this frame. + /// `None` ⇒ uncalibrated (no `BaselineCalibration::subtract()` applied). + #[cfg_attr(feature = "serde", serde(default))] + pub calibration_id: Option, + + /// Identifier of the RF encoder / model family that will consume this + /// frame (ADR-146).

We keep one struct rather than two to avoid copy-on-cross-stage. + +`calibration_id` is a `Uuid` (the workspace already depends on `uuid` — `types.rs:17`) and references the `BaselineCalibration` finalised by ADR-135. ADR-135's `BaselineCalibration` gains a `pub id: Uuid` field whose value is written here. This closes the trace from a fused semantic state back to the exact empty-room reference that conditioned it. + +`model_id`/`model_version` are `u16` (not `String` like `PoseEstimate.model_version` at `types.rs:964`) because they ride on every frame and must be cheap to copy and to serialise in fixed width. The free-form `PoseEstimate.model_version: String` remains for human-readable reporting; the `u16` pair is the machine-traceable key. + +### 2.3 `ComplexSample`: One Complex Wrapper with LE Serialisation + +CSI uses `Complex64` (`types.rs:16`), CIR uses `Complex32` (`cir.rs:27`). Neither is serialised deterministically today (`CsiFrame.data` is `serde(skip)`).

A new `CsiFrame::data_complex_samples()` view yields `ComplexSample` without copying the underlying buffer. CIR/Doppler frames (`CirFrame`, `DopplerFrame`) store `Vec` directly so all three frame types share one complex contract. + +### 2.4 Stage, Versioned, QualityScored Traits + +The six `RuvSensePipeline` stages (`mod.rs:9-23`) become uniform implementers of `Stage`.

No stage may drop these fields; the boundary rule in §2.4 makes them append-only. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **One vocabulary for ten ADRs.** ADR-137–146 reference the role→crate table (§2.1) and the three traits instead of re-deriving them, eliminating cross-ADR drift. +- **No migration.** Rejecting `ruview_*` keeps every `use` path, the publishing order, and the ADR-028 witness `source-hashes.txt` intact. +- **End-to-end traceability.** `calibration_id` + `model_id`/`model_version` on `FrameMeta` close the provenance chain the project rule mandates; a fused state can be audited back to its baseline and model. +- **Composability.** `Stage` lets ADR-138 gate stages, ADR-137 read `QualityScored`, and ADR-145 ablate any stage by trait object — no per-stage glue. +- **Witness extension is mechanical.** `CanonicalFrame::witness_hash()` plugs straight into the existing BLAKE3 path (`signature_hasher.rs`) and the `verify.py` expected-hash format (ADR-028, ADR-119 §3). + +### 3.2 Negative + +- **`CsiMetadata` grows by three fields.** Every `CsiMetadata::new()` call site (1,000+ tests) keeps compiling because the fields default, but serialised metadata changes shape — `serde(default)` handles forward reads, but any pinned metadata fixture hash in the witness bundle must be regenerated once. +- **Two complex types coexist during migration.** `ComplexSample` (Complex64) is the contract type; `cir.rs` keeps `Complex32` internally and narrows via `as_complex32()`. Until all call sites adopt the view method, both representations are live. +- **Determinism becomes a maintenance obligation.** Once `CanonicalFrame` is the witness substrate, any stage that introduces nondeterminism (HashMap iteration order, unseeded RNG, float reduction order) breaks the replay test — a stricter bar than the current `serde(skip)` payload imposes. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Contributors keep inventing `ruview_*` names because the spec uses them | Medium | Doc/code divergence; phantom crates in design talk | §2.1 table is normative and linked from `CLAUDE.md` crate table; PR review rejects new `ruview_*` crates | +| `Complex64` LE serialisation differs from the f32 CIR path, causing two witness lineages | Low | Replay hash mismatch between CSI and CIR stages | Single `ComplexSample::to_le_bytes()` is the only encoder; `as_complex32()` is a lossy *view*, never re-serialised as the witness form | +| Float reduction order in fusion (multistatic attention) is nondeterministic across thread counts | Medium | `to_canonical_bytes()` stable but `process()` output varies | Fusion stage fixes reduction order (stream-major, single-threaded reduction in the witness path); ADR-137 owns this | +| `model_id`/`model_version` u16 overflow as model families grow | Low | Wraparound collides ids | u16 gives 65k families/versions; ADR-146 owns the registry and reserves 0 = unassigned | + +--- + +## 4. Alternatives Considered + +### 4.1 Rename the Workspace to `ruview_*` (Rejected) + +Create `ruview-engine`, `ruview-signal`, `ruview-fusion`, etc., matching the spec literally. **Rejected** for the reasons in §2.1: it detaches commit history, breaks the witness `source-hashes.txt` chain, churns 35 crates' `use` paths and the publishing order, and delivers zero runtime change. The spec roles are a *lens*, not a directory layout. + +### 4.2 Separate `FrameMeta` Struct Distinct from `CsiMetadata` (Rejected) + +Define a new `FrameMeta` and convert `CsiMetadata ↔ FrameMeta` at stage boundaries. **Rejected**: it doubles the metadata type surface and forces a copy on every cross-stage hop at 20 Hz × N links. Re-exporting `CsiMetadata as FrameMeta` gives the spec vocabulary with zero conversion cost. + +### 4.3 Keep `Complex64`/`Complex32` Split, No `ComplexSample` (Rejected) + +Leave the two complex types as-is and serialise ad hoc per frame type. **Rejected**: it reproduces Gap 2 — no single byte-order guarantee, so witness hashes for CSI vs CIR frames have independent, unverifiable encodings. One wrapper with one `to_le_bytes()` is the minimal fix. + +### 4.4 Generic Pipeline via `async` Streams Instead of `Stage` (Rejected) + +Model the pipeline as a `futures::Stream` chain. **Rejected for the contract layer**: async stream combinators hide the per-stage `name()`/`version()`/`quality_score()` surface that ADR-137/138/145 need to introspect, and they complicate the deterministic-replay test (executor scheduling). A plain `Stage` trait is synchronous, introspectable, and trivially replayable; async transport can wrap it at the ingest/api edges where it belongs. + +### 4.5 Defer Provenance Fields to a Side-Channel (Rejected) + +Carry `calibration_id`/`model_id` in a parallel map keyed by `FrameId` rather than on `FrameMeta`. **Rejected**: a side map can desync from the frame, and recording/replay (`homecore-recorder`) would have to persist two artifacts that must stay consistent. Inlining on `FrameMeta` makes provenance travel with the data and survive serialisation. + +--- + +## 5.

Context + +### 1.1 The Gap + +The multistatic fusion stage decides how much to trust each sensing node and emits a single fused frame, but it discards every input it used to make that decision. Grepping the two fusion implementations confirms this: + +- **`v2/crates/wifi-densepose-signal/src/ruvsense/multistatic.rs`** (`MultistaticFuser::fuse`, lines 196–282) returns a `FusedSensingFrame` whose only quality field is `cross_node_coherence: f32` (line 80). That scalar is computed by `compute_weight_coherence()` (lines 441–460) as a normalized Shannon entropy over the softmax attention weights — a single number with no record of *which* weights produced it, which subcarriers drove the attention logits, or whether the CIR gate (`cir_gate_coherence`, lines 292–327) actually contributed or silently fell back on `CirError::UnsanitizedPhase`. +- **`v2/crates/wifi-densepose-ruvector/src/viewpoint/fusion.rs`** (`MultistaticArray::fuse`, lines 358–436) is richer — it emits `ViewpointFusionEvent` values (lines 183–219) and reports `gdi` / `n_effective` on `FusedEmbedding` — but its quality signal is still split across heterogeneous channels: a `coherence: f32` on the output struct, a `CoherenceGateTriggered { accepted }` event, and a `FusionError::CoherenceGateClosed` on the error path. There is no single auditable record that says *this fused output is trustworthy because X, Y, Z, but be aware of contradiction C*. + +The validation that *does* happen is thrown away rather than recorded: + +- `multistatic.rs::fuse` checks `timestamp_us` spread against `guard_interval_us` (lines 205–215) and returns `MultistaticError::TimestampMismatch` — but on the success path the fact that timestamps *passed* (and by how much margin) is never carried forward. A consumer cannot tell a frame fused from microsecond-aligned nodes from one fused at the 4999 µs edge of the 5000 µs guard. +- Neither implementation checks **calibration alignment**. ADR-135 finalises a per-node `BaselineCalibration` with a `captured_at_unix_s` and a `tier`, and `BaselineCalibration::subtract()` already returns `CalibrationError::TierMismatch`. But fusion does not know which baseline (if any) was applied to each node frame, so it cannot detect the dangerous case where node A's frame was baseline-subtracted against a fresh calibration and node B's against a stale one — producing amplitudes on incomparable scales that the attention softmax in `attention_weighted_fusion` (lines 364–435) will silently average together. +- **Amplitude scale comparability is assumed, not enforced.** `attention_weighted_fusion` computes a cosine similarity of each node's amplitude vector against the consensus mean (lines 384–397). Cosine similarity is scale-invariant *per node*, which masks the problem: two nodes with the same shape but a 2× gain difference look perfectly coherent, yet the weighted-sum fusion (lines 411–422) adds raw `w * amp[i]` and so the louder node dominates the fused amplitude regardless of its attention weight. The fix in §2.5 is to normalize before pooling, but today there is nothing in the codebase that does it explicitly. + +Downstream, the BFLD privacy layer cannot react to fusion quality at all. `wifi-densepose-bfld/src/event.rs` constructs a `BfldEvent` with a `privacy_class` (line 60) and masks identity fields at `Restricted` via `apply_privacy_gating()` (lines 112–117), and `privacy_gate.rs::PrivacyGate::demote` (lines 31–75) is the monotonic-demote primitive. But the demotion decision is driven by policy, not by sensing evidence. There is no path by which "the fusion engine detected that two nodes disagree about the world" can lower the emitted privacy class. A contradictory fuse is published at the same class as a clean one. + +### 1.2 What This ADR Adds + +A single, serializable `QualityScore` that travels alongside every fused frame and answers four questions with evidence rather than a scalar: + +1. **How good is this fusion?** — `base_coherence` plus the `per_node_weights` that produced it. +2. **Why is it good (or bad)?** — a list of `EvidenceRef` values naming the concrete checks that fired (coherence-gate threshold crossed, CIR dominant-tap ratio, weight entropy, calibration applied). +3. **What is wrong with it?** — a list of `ContradictionFlag` values for the validations that *failed* but were tolerated (timestamp at the guard edge, calibration-id disagreement, phase alignment failure, drift-profile conflict). +4. **Is it safe to publish at full fidelity?** — a non-empty contradiction set lowers the BFLD `privacy_class` and emits a witness record, honouring the project rule that every emitted semantic state traces to signal evidence + model/calibration version + a privacy decision. + +This is the fusion-layer counterpart to ADR-135's `CalibrationDeviationScore`: where ADR-135 scores one frame against one baseline, ADR-137 scores one *fusion* against all of its contributing node frames and their baselines. + +### 1.3 Pipeline Position + +``` +Per-node CSI (post phase_sanitizer, phase_align, ADR-135 subtract) + → CalibratedFrame wrapper ← NEW (carries calibration_id, capture_ns) + → multistatic.rs::fuse() + ├─ capture_ns epoch-alignment check → ContradictionFlag::TimestampMismatch + ├─ calibration_id agreement check → ContradictionFlag::CalibrationIdMismatch + ├─ normalize-then-concat (per §2.5) + ├─ attention_weighted_fusion() → EvidenceRef::WeightEntropy, per_node_weights + └─ cir_gate_coherence() → EvidenceRef::CirDominantTapRatio + → (FusedSensingFrame, QualityScore) ← NEW tuple return + → ruvector MultistaticArray (embedding fusion, same QualityScore contract) + → BFLD emitter + └─ if !contradiction_flags.is_empty(): + privacy_class = privacy_class.max(Restricted) (demote) + emit witness record (ADR-134 proof chain) + → BfldEvent +``` + +The `QualityScore` is computed *during* `fuse`, not bolted on afterward, because the evidence it records (attention weights, the CIR fallback decision, the timestamp margin) only exists inside that function's scope today. + +--- + +## 2.

Each variant carries the *value that crossed a threshold*, not just a boolean, so the witness record (§2.7) is reproducible. + +```rust +/// A single piece of positive evidence supporting a fusion decision. +#[derive(Debug, Clone, Copy, PartialEq)] +pub enum EvidenceRef { + /// The coherence-gate threshold was met. `coherence` is the value, + /// `threshold` the configured gate (mirrors ADR-031 coherence gate and + /// `viewpoint/coherence.rs::CoherenceGate`). + CoherenceGateThreshold { coherence: f32, threshold: f32 }, + /// The ADR-134 CIR dominant-tap ratio contributed to the gate. `ratio` + /// is `Cir::dominant_tap_ratio`; `blended` is true when it was actually + /// folded into `base_coherence` (false on `UnsanitizedPhase` fallback). + CirDominantTapRatio { ratio: f32, blended: bool }, + /// Attention-weight entropy supported a balanced (multi-node) fusion. + /// `normalized_entropy` is the `compute_weight_coherence` output. + WeightEntropy { normalized_entropy: f32, n_nodes: usize }, + /// An ADR-135 baseline was applied to every contributing frame at a + /// single agreed calibration epoch before pooling. + CalibrationApplied { calibration_id: CalibrationId, n_frames: usize }, +} +``` + +`CirDominantTapRatio { blended: false }` is itself useful evidence: it records that the CIR gate was *attempted* but fell back, which today is invisible (the `Err(CirError::UnsanitizedPhase)` arm at `multistatic.rs` line 321 silently returns `freq_coherence`). + +### 2.3 `ContradictionFlag`: what was wrong but tolerated + +`ContradictionFlag` records validations that failed without being fatal. These are the cases where today's code either hard-errors (losing the chance to degrade gracefully) or silently passes (losing the chance to warn). + +```rust +/// A tolerated disagreement detected during fusion.

Carries the observed GDI. + GeometryInsufficient { gdi: f32 }, +} +``` + +`ContradictionFlag` is the **single canonical type** for tolerated disagreements across the fusion path; it is defined here and re-used (not re-declared) by ADR-138. The first four variants originate inside `multistatic.rs::fuse` (§2.4); the last two (`CoherenceDrop`, `GeometryInsufficient`) originate one stage upstream in the ADR-138 `ArrayCoordinator` and arrive on `DirectionalEvidence.contradictions`, which `fuse` folds into the same `QualityScore.contradiction_flags` vector. `node_idx` is the index into the fused frame's node ordering; the coordinator's `NodeId` is resolved to that index at the hand-off. + +The distinction between `MultistaticError::TimestampMismatch` (hard error, line 47) and `ContradictionFlag::TimestampMismatch` is intentional: + +- The **hard error** fires when `spread > guard_interval_us` — frames are simply not from the same sensing cycle and must not be fused. +- The **soft flag** fires when `soft_guard_ns < spread <= guard_interval_us` — the frames *can* be fused (they are within the TDMA cycle) but the alignment is loose enough that the fused output should not be published at full identity fidelity. Default `soft_guard_ns = guard_interval_us / 5` (1000 ns when the guard is 5 µs). + +### 2.4 `fuse()` rework: validate-record-fuse + +`multistatic.rs::fuse` is changed to return `Result<(FusedSensingFrame, QualityScore), MultistaticError>`.

New consumers read `QualityScore.base_coherence`; the scalar on the frame is now derived, not authoritative. + +### 2.5 Normalize-then-concat: explicit `CalibratedFrame` + +Today `fuse` consumes `&[MultiBandCsiFrame]` and relies on the implicit z-score normalization buried in `hardware_norm.rs::CanonicalCsiFrame`. ADR-137 makes calibration explicit by introducing a thin wrapper that carries the calibration provenance from ADR-135 to the fuser: + +```rust +/// A node frame whose amplitude/phase have been baseline-subtracted and +/// normalized by a *named* ADR-135 calibration. The wrapper makes the +/// calibration provenance an explicit fusion input rather than an implicit +/// property of CanonicalCsiFrame. +#[derive(Debug, Clone)] +pub struct CalibratedFrame { + /// The underlying multi-band frame (per-channel amplitude/phase). + pub inner: MultiBandCsiFrame, + /// Capture-clock timestamp (ns).

Only then does the attention pool run. This closes the scale-comparability hole described in §1.1: the cosine-similarity attention logits and the weighted sum now operate on the same scale, so attention weight (not loudness) determines a node's contribution. + +**Why explicit over implicit:** `hardware_norm.rs` z-score normalization uses population statistics computed from the live signal including any occupant. The ADR-135 baseline statistics are computed from a *known-empty* room. Normalizing by the baseline (a) makes nodes comparable on a physically meaningful zero, and (b) gives the fuser the `calibration_id` it needs to detect cross-node calibration disagreement. The wrapper costs `O(K)` extra memory per node frame (two `Vec`), negligible against the `MultiBandCsiFrame` it wraps. + +### 2.6 Embedding-domain fuser: same contract + +`viewpoint/fusion.rs::MultistaticArray::fuse` is changed to return `Result<(FusedEmbedding, QualityScore), FusionError>` with `family_id: FamilyId::ViewpointEmbedding`. The mapping from its existing machinery to the unified record: + +| `QualityScore` field | Source in `viewpoint/fusion.rs` | +|----------------------|----------------------------------| +| `base_coherence` | `self.coherence_state.coherence()` (line 382) | +| `per_node_weights` | attention weights from `self.attention.fuse(...)` (line 408) — surfaced, currently internal to `CrossViewpointAttention` | +| `evidence_refs` → `CoherenceGateThreshold` | `CoherenceGate::evaluate` (line 383) plus the configured `coherence_threshold` | +| `contradiction_flags` → `DriftProfileConflict` | a viewpoint whose `snr_db` passed the filter but whose phase-diff series diverges from the coherent majority | +| `calibration_id` | from each `ViewpointEmbedding`'s source `CalibratedFrame` | + +The existing `ViewpointFusionEvent::CoherenceGateTriggered` and `FusionError::CoherenceGateClosed` are retained — they remain the *control-flow* signal — while `QualityScore` becomes the *data* signal that travels with the frame. The `CoherenceGateClosed` error still aborts fusion; `QualityScore` is only produced on the success path. A gate that is open but near the threshold records `EvidenceRef::CoherenceGateThreshold` with the margin, so a barely-open gate is auditable. + +### 2.7 Wiring contradictions into the BFLD privacy boundary + +This is where fusion quality becomes a privacy decision. The BFLD emitter (`wifi-densepose-bfld`) gains a single rule: + +> A `QualityScore` with a non-empty `contradiction_flags` set forces the emitted `BfldEvent.privacy_class` to be **at least** `Restricted`. + +Because `PrivacyClass` is ordered (`Raw=0 < Derived=1 < Anonymous=2 < Restricted=3`, `lib.rs` lines 84–94) and demotion is monotonic (`privacy_gate.rs::demote` rejects any decrease in class number), "at least Restricted" is `privacy_class.max(Restricted)` — i.e. a demote, never a promote: + +```rust +// In the BFLD emitter, before BfldEvent::with_privacy_gating(...): +let effective_class = if quality.contradiction_flags.is_empty() { + policy_class // normal policy decision +} else { + policy_class.max(PrivacyClass::Restricted) // demote on contradiction +}; +``` + +At `Restricted`, `BfldEvent::apply_privacy_gating` (event.rs lines 112–117) already nulls `identity_risk_score` and `rf_signature_hash`. So a contradictory fuse — two nodes that disagree about calibration, timestamp, phase, or drift — automatically stops leaking the identity-surface fields. The rationale: contradiction means the system is not confident *whose* signal it fused; emitting an identity-risk score or RF signature hash on an un-trusted fusion is exactly the failure the privacy layer exists to prevent. + +A non-empty contradiction set also emits a **witness record** through the ADR-134 proof chain (the `verify.py` / `expected_features.sha256` / `source-hashes.txt` witness schema, ADR-134 §2.10). The record captures: `capture_ns`, `family_id`, the `contradiction_flags` (with their carried values), the resulting `effective_class`, and a hash of `per_node_weights`. This makes every privacy demotion reproducible and auditable — satisfying the project invariant that each emitted semantic state traces to signal evidence + calibration version + a recorded privacy decision. + +``` +QualityScore.contradiction_flags non-empty + ├─ effective_class = policy_class.max(Restricted) (demote, monotonic) + ├─ BfldEvent gated → identity_risk_score = None, rf_signature_hash = None + └─ witness record { capture_ns, family_id, flags, effective_class, + blake3(per_node_weights) } → ADR-134 proof chain +``` + +**Interface boundary:** the BFLD crate depends only on `QualityScore` (a plain data struct re-exported from `wifi-densepose-signal`), not on the fusers themselves.

Consequences + +### 3.1 Positive + +- **Fusion decisions become auditable.** Every fused frame now carries the evidence that produced its coherence and the disagreements that were tolerated. A field engineer can read why a frame was trusted without re-running the fuser. +- **Calibration disagreement is caught.** The `CalibrationIdMismatch` contradiction surfaces the previously-invisible failure where nodes are normalized against baselines of different vintage — the silent amplitude-scale corruption from §1.1. +- **CIR fallback stops being silent.** `EvidenceRef::CirDominantTapRatio { blended: false }` records the `UnsanitizedPhase` fallback that today disappears at `multistatic.rs` line 321. +- **Privacy degrades safely under uncertainty.** A contradictory fusion can no longer publish identity-surface fields; the demotion is monotonic and witnessed. +- **One contract, two fusers.** The signal-domain and embedding-domain fusers expose identical quality semantics, so the streaming engine (ADR-136) and BFLD layer treat them uniformly. +- **Traceability invariant satisfied.** Each `BfldEvent` traces to a `QualityScore` → `EvidenceRef`s (signal evidence) + `calibration_id` (calibration version) + the recorded `effective_class` (privacy decision). + +### 3.2 Negative + +- **Breaking signature change.** Both `fuse` functions change their return type to a tuple. Every call site and every existing test (multistatic.rs and viewpoint/fusion.rs) must destructure. This is mechanical but touches ~25 test functions. +- **`CalibratedFrame` wrapper churn.** `fuse` no longer takes `&[MultiBandCsiFrame]` directly; callers must wrap, threading the ADR-135 calibration through. Uncalibrated nodes pass `calibration_id: None` and lose the `CalibrationApplied` evidence (but still fuse). +- **Per-frame allocation.** `evidence_refs` and `contradiction_flags` are `Vec`s. In the common clean-fuse case they hold 2–3 small `Copy` enums; the allocation is bounded but non-zero on the hot path. Mitigation: a `SmallVec` could be substituted if profiling shows pressure (deferred — not premature). + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Over-eager demotion: a benign loose timestamp at the guard edge demotes every frame to Restricted, suppressing identity features the deployment legitimately needs | Medium | Identity-risk scoring effectively disabled in a node array with marginal clock sync | `soft_guard_ns` is configurable (default `guard/5`); ADR-138's `ArrayCoordinator` clock-quality gating can raise the bar so timestamp contradictions only fire on genuinely degraded clocks | +| `DriftProfileConflict` false-positives when one node legitimately sees motion the others cannot (occlusion geometry) | Medium | Spurious privacy demotions in multi-room arrays with partial line-of-sight | Conflict requires a *majority* disagreement, not any single dissenting node; threshold tunable per deployment | +| Witness record volume: a flapping contradiction produces a witness record per cycle (20 Hz) | Low | Witness log growth | Coalesce identical consecutive contradiction sets; emit a witness record only on contradiction-set *transitions*, not every frame | +| `calibration_id` derivation collides for two devices recalibrated in the same second | Low | Two nodes appear to agree on calibration when they don't | `CalibrationId` is `hash(device_id, captured_at_unix_s)`, not the timestamp alone | + +--- + +## 4. Alternatives Considered + +### 4.1 Keep the scalar `cross_node_coherence`, add a separate log channel + +Rejected. A side-channel log decouples the quality record from the frame it describes; a consumer cannot atomically obtain "this frame and exactly the evidence that produced it." The BFLD privacy decision must be made from the same data that produced the frame, in the same call. A `QualityScore` returned in the tuple guarantees that coupling; a log does not. + +### 4.2 Boolean flags instead of evidence-carrying enums + +Rejected. `passed_coherence: bool` cannot be reproduced in a witness record — the threshold and value are lost. ADR-135 and ADR-134 both made determinism-by-recorded-value a requirement of the proof chain (`expected_features.sha256`). A boolean breaks that chain. The enums carry the crossing value precisely so the witness hash is reproducible. + +### 4.3 Hard-error on every contradiction (no graceful degradation) + +Rejected. Promoting `CalibrationIdMismatch` and soft `TimestampMismatch` to fatal `MultistaticError`s would make the array brittle: any transient clock skew or mid-session recalibration would drop the entire fused frame. The whole point of the contradiction flag is that the fusion is *usable but not fully trusted* — degrade fidelity (privacy demote), don't drop data. The genuinely unfusable cases (spread beyond the guard, dimension mismatch) remain hard errors. + +### 4.4 Put the demotion logic in the fuser, not the BFLD emitter + +Rejected. The fuser produces evidence; it should not know the privacy policy. Privacy class ordering and the `Restricted` semantics live in `wifi-densepose-bfld` (`PrivacyClass`, `PrivacyGate`). Keeping the `max(Restricted)` decision in the emitter preserves the bounded-context separation: signal-processing crates compute *what is true and how confident*, the BFLD crate decides *what may be emitted*. The fuser exports a data struct; the emitter owns the policy. + +### 4.5 Reuse `ViewpointFusionEvent` for evidence + +Rejected. `ViewpointFusionEvent` (viewpoint/fusion.rs lines 183–219) is an internal event-sourcing log for the `MultistaticArray` aggregate and exists only in the ruvector crate; it does not travel with the frame and is unknown to the signal-domain fuser or the BFLD crate. `QualityScore` is the shared, frame-attached contract both fusers and the privacy layer agree on. + +--- + +## 5.

Context + +### 1.1 The Gap + +Searching across the two named crates for `LinkGroup`, `ArrayCoordinator`, `clock_quality`, `DirectionalEvidence`, and `FreqSet` finds no production module. The pieces that an MLO-aware coordinator would compose all exist, but each is wired to a *single* CSI stream, a *single* clock domain, and emits a *hard fused output* rather than weighted evidence. Concretely: + +- **`ruvsense/multiband.rs`** has `MultiBandCsiFrame { node_id, timestamp_us, channel_frames: Vec, frequencies_mhz: Vec, coherence }` and a `MultiBandBuilder` that fuses per-channel rows from a *channel-hopping* radio (one ESP32-S3 cycling 1/6/11). This is the closest thing to a per-band feature stream, but it models **sequential** channel hopping on one radio, not **simultaneous** WiFi-7 Multi-Link Operation (MLO) where bands stream concurrently. There is no aggregate that tracks which bands are currently *live* versus which have *dropped out*, and `coherence` is a single Pearson scalar (`compute_cross_channel_coherence`), not an inter-band consensus with promotion semantics. + +- **`ruvsense/multistatic.rs`** has `MultistaticFuser::fuse(&[MultiBandCsiFrame]) -> FusedSensingFrame`. It already validates a `guard_interval_us` timestamp spread (`MultistaticConfig.guard_interval_us`, default 5000 µs) and computes `geometric_diversity(&[[f32;3]])` from node positions. But: (a) the timestamp spread is a hard accept/reject — there is no notion of *clock quality* (a node whose clock is merely *uncertain* is treated identically to one whose clock is *good*); (b) `geometric_diversity()` is a free function returning a bare `f32`, not gated into the fusion decision; (c) the output `FusedSensingFrame` is a committed `fused_amplitude`/`fused_phase` pose-bearing artifact, not directional evidence with credence intervals. + +- **`viewpoint/geometry.rs`** has `GeometricDiversityIndex::compute(azimuths, node_ids) -> Option` with `value`, `n_effective`, `worst_pair`, `is_sufficient()` (threshold `value >= PI/N`), plus `CramerRaoBound::estimate(target, &[ViewpointPosition]) -> Option` returning `crb_x`, `crb_y`, `rmse_lower_bound`, `gdop`. This is exactly the GDI + Cramér-Rao machinery this ADR needs to convert into a gate and into credence intervals — but nothing currently calls it from the multistatic path. The two `geometric_diversity` implementations (the `multistatic.rs` free function and the `geometry.rs` `GeometricDiversityIndex`) are unaware of each other. + +- **`viewpoint/coherence.rs`** has `CoherenceState` (rolling phasor window with `push`/`coherence()`) and `CoherenceGate { threshold, hysteresis, evaluate() }`. The gate already implements hysteresis and a duty cycle. But it gates **only on phase coherence** — there is no clock-quality term, and no "contradiction" notion: a coherence drop merely closes the gate, it does not demote a band/group to monitoring-only nor flag the contradiction for downstream. + +- **`viewpoint/fusion.rs`** has `MultistaticArray` (the DDD aggregate root) with `submit_viewpoint`, `push_phase_diff`, `fuse() -> FusedEmbedding`, `compute_gdi()`, and a `ViewpointFusionEvent` enum (`ViewpointCaptured`, `TdmCycleCompleted`, `FusionCompleted`, `CoherenceGateTriggered`, `GeometryUpdated`). `fuse()` already filters by SNR and gates on coherence, returning `FusionError::CoherenceGateClosed` when the environment is unstable. But the aggregate is keyed on **embeddings** (AETHER 128-d vectors) and produces a **pose-feeding `FusedEmbedding`** — there is no per-band lifecycle, no clock-quality input, and the "gate closed" path silently drops the cycle rather than demoting to a monitoring-only state that still emits evidence. + +- **`wifi-densepose-hardware/src/sync_packet.rs`** is fully implemented: `SyncPacket` decodes the ADR-110 §A0.12 wire format (magic `0xC511A110`, 32 bytes LE), exposes `local_minus_epoch_us()`, `apply_to_local()`, and `mesh_aligned_us_for_sequence(frame_seq, fps_hz)`. The sensing server (`wifi-densepose-sensing-server/src/main.rs`) already dispatches on `SYNC_PACKET_MAGIC` and applies a 9-second staleness gate (`mesh_aligned_us_for_csi_frame`). What is missing: a **clock-quality score** derived from the sync stream (offset dispersion / leader-vs-follower / staleness) that the *signal-domain* fusion can consult. The hardware crate recovers `mesh_aligned_us` but never propagates a *quality* of that alignment into `multistatic.rs` or `viewpoint/`. + +The consequence: the array treats every node as if its clock were perfect and its geometry adequate, and it commits to a fused pose even when (a) only one MLO band survived, (b) the contributing nodes are clustered (low GDI), or (c) a node's clock has drifted past the point where its phase is comparable to its peers. ADR-137 (sibling, Proposed) requires every fused output to carry **evidence references and contradiction flags**; ADR-136 (sibling, Proposed) defines the `FrameMeta` frame contract that should carry `mesh_aligned_us` and clock metadata per frame. This ADR supplies the missing middle: a lifetime-managed `LinkGroup` that knows which bands are live, and an `ArrayCoordinator` service that gates on geometry *and* clock quality and emits `DirectionalEvidence` instead of a hard decision. + +### 1.2 What "LinkGroup" and "ArrayCoordinator" Mean Here + +- A **LinkGroup** is a lifetime-managed aggregate representing one *physical link* operating WiFi-7 MLO: a set of concurrent bands (2.4 / 5 / 6 GHz) that the radio streams simultaneously, each producing its own `CanonicalCsiFrame`. The LinkGroup wraps a `FreqSet` (the declared band membership) plus a rolling `Vec` per band, and tracks **band lifecycle** — a band can `enter` (start streaming), `exit` (drop out, e.g. 6 GHz lost when the AP reboots), and be `promoted` to the consensus set once it agrees with its peers. This is distinct from today's `MultiBandCsiFrame`, which is a *snapshot* of one hop cycle with no membership lifecycle. + +- An **ArrayCoordinator** is a **service** (not an aggregate). It consumes a set of `LinkGroup`s plus the per-node frames already modelled by `multistatic.rs`, applies two gates — a **geometry gate** (GDI / Cramér-Rao from `viewpoint/geometry.rs`) and a **clock-quality gate** (ADR-110 sync dispersion) — and returns `DirectionalEvidence`: attention weights per viewpoint plus credence intervals derived from the Cramér-Rao bound. It does **not** decide pose. The pose/semantic decision is downstream (ADR-137 fusion-engine quality scoring); the coordinator only says "here is what the array can and cannot see right now, and how much to trust each direction." + +### 1.3 Why Not a Single Hard Gate + +The existing `CoherenceGate::evaluate()` and `MultistaticConfig.guard_interval_us` are both **binary**: update / no-update, accept / reject. WiFi-7 MLO and multi-node arrays degrade *gracefully* — losing the 6 GHz band, or a node whose clock dispersion rose from 40 µs to 180 µs, does not invalidate the array; it narrows what it can resolve and widens the credence interval. A hard gate throws away usable evidence. The decision below replaces the binary gates with a **graded** coordinator output that downgrades rather than discards, and feeds the graded result into ADR-137's contradiction machinery. + +### 1.4 Pipeline Position + +``` +Per-band CSI (MLO: 2.4 / 5 / 6 GHz concurrent) + → multiband.rs MultiBandBuilder (per-band CanonicalCsiFrame rows) + → LinkGroup::ingest() ← NEW (band enter/exit + consensus promote) + → ArrayCoordinator::coordinate() ← NEW (service: GDI gate + clock-quality gate) + │ consumes: Vec, node_frames, Vec (ADR-110) + │ uses: GeometricDiversityIndex + CramerRaoBound (viewpoint/geometry.rs) + │ ClockQualityGate ← NEW (wraps viewpoint/coherence.rs CoherenceGate) + ▼ + → DirectionalEvidence ← NEW (attention weights + credence intervals) + → multistatic.rs MultistaticFuser.fuse() (consumes weights, NOT a re-decision) + → ADR-137 FusionEngine quality scoring + contradiction flags +``` + +The coordinator sits *between* per-band ingestion and the existing `MultistaticFuser`. It does not replace `fuse()`; it supplies the weights `fuse()` already wants (today `attention_weighted_fusion` derives them internally from amplitude similarity only) and the contradiction flags ADR-137 consumes. + +--- + +## 2. Decision + +### 2.1 `LinkGroup`: Lifetime-Managed MLO Aggregate + +A `LinkGroup` is added to `ruvsense/multiband.rs` (it composes the existing `MultiBandCsiFrame` and `CanonicalCsiFrame`).

The `consensus_frame()` output is intentionally a `MultiBandCsiFrame`, so the existing `MultistaticFuser` consumes it unchanged. + +**Why an aggregate, not a snapshot.** MLO band membership is *stateful*: the 6 GHz band dropping for 250 ms and returning is a different physical situation from a node permanently losing 6 GHz. A snapshot (`MultiBandCsiFrame`) cannot represent "this band exited and we are now operating degraded." The lifecycle (`Pending → Live → Promoted`, with `→ Exited` and `→ Demoted` transitions) is the minimum state required to (a) feed graceful degradation into the coordinator and (b) emit the band-level contradiction events ADR-137 wants. + +### 2.2 `ClockQualityScore` and the Clock-Quality Gate + +A clock-quality term is derived from the ADR-110 `SyncPacket` stream and folded into a gate alongside the existing phase-coherence gate.

A node whose dispersion has risen to 2× the measured baseline (200 µs) has lost roughly one phase wrap of cross-node comparability at 5 GHz (wavelength ≈ 5 cm; 200 µs of clock skew at sensing motion velocities corrupts the inter-node phase term that `attention_weighted_fusion` relies on). Below 200 µs the node is admitted; between 200 µs and the staleness ceiling it is `MonitorOnly` (evidence yes, environment update no); above the 9 s age ceiling — the same staleness gate the sensing server already enforces (`main.rs::mesh_aligned_us_honors_9s_staleness_gate`) — it is rejected. + +**Why gate environment updates specifically.** The clock term must not block *evidence emission* — a clock-degraded node still sees real motion and should contribute weighted evidence. It must block *environment/model updates* (ADR-030 field model, ADR-031 model update path), because those updates assume cross-node phase comparability that a dispersed clock breaks. `MonitorOnly` encodes exactly this: contribute to `DirectionalEvidence`, do not promote to a model/environment change. This mirrors the existing `CoherenceGate` semantics ("only allow model updates when coherence exceeds threshold") and extends them with the clock dimension. + +### 2.3 `ArrayCoordinator`: a Service, Not an Aggregate + +`ArrayCoordinator` is added to `viewpoint/fusion.rs` alongside `MultistaticArray`.

The coordinator's job spans *multiple* aggregates (every node's `LinkGroup` plus the array) and is *read-mostly*: it inspects state and projects evidence, but the authoritative state transitions (band promotion, viewpoint upsert) belong to the aggregates. Putting cross-aggregate gating logic in a stateless service keeps the aggregate boundaries clean (DDD) and makes the coordinator trivially testable with synthetic inputs. + +### 2.4 Wiring the ADR-110 SyncPacket Decoder Into the Pipeline + +Today `SyncPacket` is decoded in `wifi-densepose-sensing-server/src/main.rs` and used only to recover `mesh_aligned_us`. This ADR widens that path so the recovered alignment carries a *quality*: + +1. The sensing server already keeps `NodeState::latest_sync: Option` and `latest_sync_at: Option`. Add a rolling buffer `NodeState::sync_offsets: VecDeque` of the last N `local_minus_epoch_us()` values and an EMA. From these, build a `ClockQualityScore { offset_stdev_us, stratum, age_us, valid }` per node per cycle. + - `stratum` is derived from `SyncPacketFlags::is_leader` (leader = 0, follower = 1; deeper strata are reserved). + - `age_us` is `now - latest_sync_at` in the mesh domain. + - `valid` is `latest_sync.flags.is_valid`. +2. Per ADR-136, the per-frame `FrameMeta` contract gains `mesh_aligned_us: Option` and `clock_quality: Option`, populated at frame ingestion by pairing `(node_id, sequence)` against the most recent `SyncPacket` (exactly the pairing `mesh_aligned_us_for_sequence` already implements). This keeps the *signal* crates free of any UDP/socket dependency — they receive `FrameMeta`, not raw packets. +3. The `ArrayCoordinator::coordinate()` call receives `clock_per_node: &[ClockQualityScore]` extracted from those `FrameMeta` records. No new socket code lands in `wifi-densepose-signal` or `wifi-densepose-ruvector`; the hardware crate remains the only owner of the wire format (`SYNC_PACKET_MAGIC = 0xC511A110`). + +This preserves the existing crate dependency direction: hardware → (FrameMeta) → signal/ruvector. The coordinator never imports `wifi-densepose-hardware`; it sees only the `ClockQualityScore` value object. + +### 2.5 Contradiction-to-Environment-Change Semantics + +The coordinator converts two array-level conditions into ADR-137 contradiction flags, and uses them to demote rather than to commit: + +- **Coherence drop > 2σ.** Each node's `CoherenceState` already maintains a rolling phasor coherence. The coordinator additionally tracks a rolling mean/std of that coherence per node (Welford, consistent with ADR-135's reuse of `WelfordStats`). When the current coherence falls more than `contradiction_sigma` (default 2.0) below the rolling mean, the coordinator (a) raises `ContradictionKind::CoherenceDrop { magnitude }`, and (b) the node's `ClockQualityGate` returns at most `MonitorOnly` for that cycle — its frame contributes evidence but cannot trigger an environment/model update. This is the signal-domain analogue of `LinkGroupEvent::BandDemoted { reason: CoherenceContradiction }`. + +- **GDI below the sufficiency floor.** `GeometricDiversityIndex::is_sufficient()` already encodes the `value >= (2π/N) × 0.5` floor. When the admitted set's GDI is insufficient, the coordinator raises `ContradictionKind::GeometryInsufficient { magnitude: gdi.value }` and widens the credence interval (the Cramér-Rao `rmse_lower_bound` already grows automatically as geometry degrades, so this flag is advisory for ADR-137, not a separate widening). + +A `LinkGroup` band demotion (`BandDemoted`) is forwarded verbatim as `ContradictionKind::BandDemoted`. In all three cases the rule is identical and is the core of this ADR: **a contradiction demotes to monitoring-only; it never forces an environment change.** Only a sustained *consensus* (admitted nodes agreeing across a window) promotes an environment update — and that promotion is owned downstream by ADR-137, which receives the coordinator's `DirectionalEvidence` complete with its contradiction list. + +### 2.6 Provenance / Evidence Tracing + +Per the project rule that every semantic state traces to signal evidence + model version + calibration version + privacy decision, the `DirectionalEvidence` struct is designed as the *evidence* half of that chain: + +- **Signal evidence**: the per-node `weights` and `gate_decisions` are the audit trail of which viewpoints (and which MLO bands, via the `LinkGroup` consensus) contributed and how much. +- **Calibration version**: when an ADR-135 `BaselineCalibration` is loaded for a node, its `captured_at_unix_s`/device id flow through `FrameMeta`; the coordinator does not re-derive calibration but passes it through so ADR-137 can stamp it. +- **Model / privacy version**: these are not the coordinator's concern (it makes no model inference and no privacy decision); ADR-137 attaches `model_version` and the active privacy decision when it consumes `DirectionalEvidence`. The coordinator's contract is to make the evidence and contradiction set *complete enough* that ADR-137 can construct the full provenance tuple without re-reading raw frames. + +### 2.7 Downstream Consumers and Interface Boundaries + +| Consumer | What it receives | Change required | +|----------|-----------------|-----------------| +| `multistatic.rs::MultistaticFuser::fuse()` | `DirectionalEvidence.weights` instead of internally-derived amplitude-cosine weights | `MultistaticConfig` gains `external_weights: Option>`; when present, `attention_weighted_fusion` uses them rather than recomputing. Backward compatible (`None` = today's behaviour). | +| `multiband.rs::MultiBandBuilder` | Unchanged; `LinkGroup::consensus_frame()` produces a `MultiBandCsiFrame` it already understands | No change to `MultiBandBuilder`; `pearson_correlation_f32` promoted to `pub(crate)` for `LinkGroup` reuse | +| `viewpoint/fusion.rs::MultistaticArray` | Coordinator runs *before* `fuse()`; the `CoherenceGateClosed` path is replaced by `MonitorOnly` evidence | New `ViewpointFusionEvent::DirectionalEvidenceEmitted { gdi, n_admitted, n_monitoring }`; `fuse()` no longer hard-drops on closed coherence — it returns evidence with zero admitted nodes | +| `viewpoint/geometry.rs` | Called by the coordinator (`GeometricDiversityIndex`, `CramerRaoBound`) | No API change; the existing `is_sufficient()` and `rmse_lower_bound` are exactly the gate/credence primitives | +| `viewpoint/coherence.rs` | Hosts the new `ClockQualityScore` / `ClockQualityGate` next to `CoherenceGate` | New types added; existing `CoherenceGate`/`CoherenceState` unchanged and reused as the phase term | +| ADR-137 FusionEngine | `DirectionalEvidence` (weights + credence + `contradictions`) | The coordinator is ADR-137's upstream; `ContradictionFlag` is the agreed hand-off type | +| ADR-136 streaming engine | Populates `FrameMeta.mesh_aligned_us` + `clock_quality` | The coordinator reads these from `FrameMeta`; ADR-136 owns the frame contract | + +**Interface boundary statement.** The coordinator's only inputs are value objects (`ViewpointPosition`, `f32` coherence, `ClockQualityScore`, `LinkGroupEventRef`); its only output is the `DirectionalEvidence` value object. It imports from `viewpoint::geometry` and `viewpoint::coherence` within the same crate, and is invoked by the sensing server / streaming engine which assemble the inputs. It does **not** import `wifi-densepose-hardware`, does **not** touch sockets, and does **not** make pose or privacy decisions. + +### 2.8 Test Plan / Acceptance Criteria + +**T1 — LinkGroup band lifecycle (unit).** Construct a `LinkGroup` with `FreqSet::new(vec![2412, 5180, 5955])`. Ingest 2.4 + 5 GHz frames that correlate (consensus > 0.6) for 10 cycles; ingest 6 GHz frames that do not. Assert: 2.4 and 5 GHz reach `BandState::Promoted` (emitting `BandPromoted`); 6 GHz stays `Live`; `promoted_bands() == [2412, 5180]`; `consensus_frame()` yields a 2-band `MultiBandCsiFrame`. + +**T2 — Band exit and re-entry (unit).** With the same group, stop feeding 6 GHz for `exit_after_missed` (5) cycles → assert `BandExited` emitted and state `Exited`. Resume 6 GHz → assert `BandEntered` emitted and state returns to `Live`. + +**T3 — Clock-quality gate thresholds (unit).** Build `ClockQualityScore`s: (a) `offset_stdev_us = 50, valid = true, age_us = 1_000_000` → `quality() > 0.8` and gate `Admit`; (b) `offset_stdev_us = 250` (> 200 floor) but coherent → gate `MonitorOnly`; (c) `age_us = 10_000_000` (> 9 s) → gate `Reject { ClockStale }`; (d) `valid = false` → `Reject { ClockInvalid }` and `quality() == 0.0`. + +**T4 — ArrayCoordinator geometry gate + credence (unit).** Four nodes at the corners of a 5×5 m room (reuse `geometry.rs::gdi_four_corners` layout), all `Admit`. Assert: `gdi.is_sufficient()`; `credence_rmse_m` is `Some` and decreases when a 5th well-placed node is added (mirrors `crb_decreases_with_more_viewpoints`); `weights` sum to 1.0; `n_admitted == 4`. + +**T5 — Clustered nodes raise GeometryInsufficient (unit).** Four nodes clustered within 0.12 rad (reuse `gdi_clustered_viewpoints_have_low_value`). Assert `ContradictionKind::GeometryInsufficient` present and `credence_rmse_m` is much larger than T4. + +**T6 — Coherence-drop contradiction demotes, not decides (unit).** Feed one node a stable coherence (~0.8) for 30 cycles to seed the rolling mean, then a single 0.2 coherence (> 2σ drop). Assert: `ContradictionKind::CoherenceDrop` raised for that node; its gate decision is at most `MonitorOnly`; the node still appears in `weights` (evidence preserved); `n_monitoring >= 1`. + +**T7 — SyncPacket → ClockQualityScore (unit, hardware crate test reuse).** Using the canonical COM9 follower packet from `sync_packet.rs` (`local_minus_epoch_us() == 1_163_565`) and the COM12 leader packet, build offset series and assert: leader → `stratum == 0`, high `quality()`; follower with low dispersion → `Admit`. Assert no `wifi-densepose-hardware` symbol leaks into the coordinator's public API (compile-fence test). + +**T8 — Determinism proof (CI-compatible, extends ADR-028 chain).** Drive a fixed synthetic 3-band, 4-node scenario through `LinkGroup::ingest` → `ArrayCoordinator::coordinate`, serialise `DirectionalEvidence.weights` (rounded to f32) and the sorted contradiction kinds, and SHA-256 the result. Record under `archive/v1/data/proof/expected_features.sha256` as `array_coordinator_evidence_v1`; `verify.py` regenerates and asserts the hash. + +**Acceptance gate**: `cargo test -p wifi-densepose-signal -p wifi-densepose-ruvector --no-default-features` passes all of T1–T8; no new `unsafe`; the coordinator's public API contains no type from `wifi-densepose-hardware`. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Graceful MLO degradation.** Losing the 6 GHz band narrows resolution and widens the credence interval rather than invalidating the link. The `LinkGroup` lifecycle makes "degraded but operating" a first-class state instead of an undetected silent failure. +- **Clock quality becomes observable and actionable.** Today a drifting node is treated identically to a good one until it crosses the 9 s staleness cliff. The `ClockQualityScore` exposes the *continuum*, and `MonitorOnly` lets a clock-degraded node still contribute evidence without corrupting environment updates. +- **Evidence, not premature decisions.** The coordinator emits `DirectionalEvidence` with attention weights and Cramér-Rao credence intervals, giving ADR-137 the provenance it needs and removing the hard `CoherenceGateClosed` drop that currently discards usable cycles. +- **Reuse over reinvention.** GDI, Cramér-Rao, coherence gate, sync-packet decode, and Pearson consensus already exist and are tested; this ADR composes them. The two duplicate `geometric_diversity` notions converge on `viewpoint/geometry.rs`. +- **Clean crate boundaries preserved.** No socket or wire-format code enters the signal/ruvector crates; the `FrameMeta` contract (ADR-136) is the only coupling point. + +### 3.2 Negative + +- **More state to manage.** `LinkGroup` adds per-band lifecycle state and an event buffer. For a 4-node, 3-band array that is 12 band state machines plus the coordinator — modest, but non-zero, and the events must be drained or they accumulate (bounded like `MultistaticArray::max_events`). +- **Two gates instead of one.** Operators and tests must reason about coherence *and* clock quality. The `MonitorOnly` middle state, while useful, is a third outcome that downstream code (ADR-137) must handle explicitly rather than a simple boolean. +- **Depends on sibling ADRs not yet landed.** `FrameMeta` (ADR-136) and the contradiction-consumer (ADR-137) are both Proposed. Until they land, the coordinator can be tested with synthetic `ClockQualityScore`s but cannot be wired end-to-end. The `mesh_aligned_us` plumbing exists today only in the sensing server, not in a shared `FrameMeta`. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| `offset_stdev_us` is noisy on small sync windows, causing gate flapping between Admit/MonitorOnly | Medium | Weights jitter cycle-to-cycle | Use the `CoherenceGate` hysteresis pattern for the clock term too: open at 200 µs, close only above 240 µs; EMA the offset series (the firmware already EMA-smooths, per `smoothed_used` flag) | +| Inter-band consensus false-demotes a band that is genuinely seeing a different multipath (legitimately decorrelated across 2.4 vs 6 GHz) | Medium | A useful band drops out of consensus | `promote_consensus` default 0.6 is deliberately lenient; band frequency-dependent decorrelation is expected, so demotion requires sustained loss, and a demoted band still streams (it is not Exited) | +| Cramér-Rao credence assumes a centroid target; a real target off-centroid has a different bound | Low | Credence interval mildly optimistic/pessimistic off-centre | Documented as a centroid-referenced bound; ADR-137 may recompute per-hypothesis if it needs target-specific credence | +| ADR-136 `FrameMeta` shape changes during its own design, breaking the `clock_quality` field | Medium | Re-plumb the coordinator's input extraction | Coordinator consumes a `ClockQualityScore` value object, not `FrameMeta` directly; only the thin extraction adapter changes | + +--- + +## 4. Alternatives Considered + +### 4.1 Extend `MultiBandCsiFrame` In Place Instead of a New `LinkGroup` + +Rejected. `MultiBandCsiFrame` is a value-type snapshot consumed throughout `multistatic.rs` and the sensing server; bolting mutable band-lifecycle state onto it would break its `Clone`-cheap, pass-by-value contract and entangle every consumer with lifecycle logic. A separate aggregate that *produces* `MultiBandCsiFrame` via `consensus_frame()` keeps the snapshot type immutable and the lifecycle isolated. + +### 4.2 Make `ArrayCoordinator` Part of `MultistaticArray` + +Rejected. `MultistaticArray` is an aggregate root with a single-aggregate invariant boundary (its viewpoints, its coherence window). Cross-aggregate gating that reads every node's `LinkGroup` belongs in a domain service, not inside an aggregate — folding it in would force the aggregate to hold references to other aggregates, violating DDD boundaries and making it untestable in isolation. The service is stateless-per-call and trivially unit-testable. + +### 4.3 Keep the Binary Coherence Gate, Add Clock as a Second Binary Gate + +Rejected. Two ANDed binary gates still throw away graded information: a node that is 90% coherent with a 210 µs clock would be hard-rejected, discarding real evidence. The `MonitorOnly` middle state is the whole point — it admits the evidence while withholding the environment update. A pure binary design cannot express "trust this for motion evidence but not for re-learning the room." + +### 4.4 Derive Clock Quality on the ESP32 and Ship a Single Byte + +Rejected for now. The ESP32 firmware already computes the EMA offset (the `smoothed_used` flag), and shipping a pre-computed quality byte would save host work. But the host has the *full* offset series across all nodes and can compute a *comparative* stratum and dispersion the single node cannot. Per-node self-assessment also cannot detect a node that is confidently wrong. Host-side derivation from the existing `SyncPacket` stream keeps the firmware unchanged (no reflash) and centralises the cross-node comparison. This may revisit once ADR-110 firmware exposes a richer sync telemetry field. + +### 4.5 Use Raw `guard_interval_us` Rejection for Clock Handling + +Rejected. The existing `MultistaticConfig.guard_interval_us` (5 ms spread) is a *timestamp-alignment* sanity check, not a clock-*quality* measure — it catches gross desync but says nothing about the sub-millisecond dispersion that corrupts cross-node phase. The two are complementary: `guard_interval_us` stays as the coarse alignment precondition; `ClockQualityScore.offset_stdev_us` is the fine-grained quality term feeding the gate. + +--- + +## 5.

Context + +### 1.1 The Gap + +There is no single, queryable model of *the environment a RuView installation senses*. The spatial knowledge that exists in the workspace is fragmented across four crates, each holding one projection of "where things are" with no edges connecting them: + +- **`v2/crates/wifi-densepose-geo`** holds the *outdoor / global* frame. `src/types.rs` defines `GeoPoint { lat, lon, alt }` (the ADR-044 WGS84 anchor), `GeoBBox`, `GeoScene`, and `GeoRegistration { origin, heading_deg, scale }`. `src/coord.rs` implements `wgs84_to_enu()` / `enu_to_wgs84()` — the exact transform needed to pin a room into a local East-North-Up frame relative to a `GeoPoint`. But `GeoScene` only models buildings and roads (`OsmFeature::Building`, `OsmFeature::Road`); it has no concept of an interior room, wall, doorway, sensor placement, or a person inside. +- **`v2/crates/homecore/src/registry.rs`** holds the *entity / automation* frame. `EntityEntry` carries `area_id: Option` and `device_id: Option` (mirroring Home Assistant `core.entity_registry` v13 per ADR-127). This is the canonical handle for "which room an entity is in" — but `area_id` is an opaque string with no geometry, no adjacency, and no link to the sensors that observe it. +- **`v2/crates/wifi-densepose-mat/src/domain/scan_zone.rs`** holds the *sensing geometry* frame. `ScanZone` has `ZoneBounds` (Rectangle/Circle/Polygon), `SensorPosition { id, x, y, z, sensor_type }`, and `contains_point()`. This is the only place that knows sensor coordinates relative to a monitored area — but its coordinates are bare `f64` meters with no declared origin, no link to `homecore` `area_id`, and no link to a `GeoPoint`. +- **`v2/crates/ruv-neural/ruv-neural-graph/src/petgraph_bridge.rs`** demonstrates the *graph algorithm* pattern we want: it bridges a domain `BrainGraph` to `petgraph::graph::{Graph, UnGraph}` (`to_petgraph()` / `from_petgraph()`) so that petgraph's traversal/shortest-path algorithms run over a typed domain model. But its nodes are bare `usize` and its edges carry only an `f64` weight plus a `ConnectivityMetric` enum — there is no node *type* and no edge *semantics*. It is the right mechanical pattern, the wrong domain. + +Concretely, what is **missing**: + +1. **No node typing.** Nothing in the workspace represents `room`, `zone`, `wall`, `doorway`, `sensor`, `rf_link`, `person_track`, `object_anchor`, `event`, or `semantic_state` as first-class graph nodes with a shared identity space. +2. **No typed edges.** There is no `observes` edge (sensor → node), no `located_in` (person → room), no `adjacent_to` (room ↔ room through a doorway), no `supports` / `contradicts` (evidence relations), no `derived_from` (provenance), and no `privacy_limited_by` (sensor capability constrained by a privacy mode). +3. **No provenance / contradiction tracking.** ADR-137's fusion engine produces `EvidenceRef` and `ContradictionFlag` records, but there is nowhere to *attach* them — they cannot point at the world entity they support or contradict. +4. **No privacy-impact rollup.** ADR-141's privacy control plane will define named modes and per-action allow/deny, but no structure answers "given the current mode, which world nodes can sensor X still observe?" +5. **No persistence of topology.** Each of the four crates persists independently (HomeCore to `core.entity_registry`, geo to a tile cache, MAT in memory). There is no single artifact a RuView appliance can load at boot to reconstitute "the rooms, the sensors, who's where, and why we believe it." + +This ADR closes the gap with a **WorldGraph**: a typed `petgraph` over a serde-serializable node enum and typed edges, persisted as an RVF bundle, pinned to a `GeoPoint`, keyed by HomeCore `area_id`, and carrying ADR-137 evidence/contradiction provenance plus ADR-141 privacy constraints. + +### 1.2 What "WorldGraph" Means Here + +The WorldGraph is an **environmental digital twin** of a *single installation*: the static room/zone/wall/doorway/sensor topology plus the dynamic person/object/event/semantic overlay that sensing produces. It is: + +- A `petgraph::stable_graph::StableDiGraph` (directed; stable indices so node removal does not invalidate other handles). +- The single authority for *spatial identity*: every `area_id` in HomeCore, every `ScanZone` in MAT, and every sensor placement in ADR-113 maps to exactly one WorldGraph node. +- Append-with-provenance, not overwrite: a node update that supersedes a prior belief adds a `derived_from` edge to the old state and (when sources disagree) a `contradicts` edge, so the graph retains *why* it holds its current belief. + +It is **not**: + +- A real-time per-frame buffer. The streaming engine (ADR-136) owns per-frame data; the WorldGraph is updated at the *event / semantic-state* cadence (sub-Hz to low-Hz), not the 20 Hz CSI cadence. +- A geometry/CAD engine. Walls and doorways are coarse topological elements (an adjacency relation + a 2D segment), not a BIM model. +- A temporal reconfiguration history. v1 models the *current* static topology only; topology reconfiguration history is deferred to ADR-142's evolution tracker (see §2.7). + +### 1.3 Frame and Identity Context + +A WorldGraph is pinned to one `GeoRegistration { origin: GeoPoint, heading_deg, scale }` (ADR-044, already in `geo/src/types.rs`). All interior coordinates are **local ENU meters** relative to `origin`, exactly the frame produced by `geo::coord::wgs84_to_enu()`. This means: + +- A `room`/`zone` node carries its `ScanZone`-style `ZoneBounds` in ENU meters and can be re-projected to WGS84 via `enu_to_wgs84()` for the ADR-044 map overlay. +- A `sensor` node reuses the `SensorPosition { x, y, z }` semantics from `scan_zone.rs`, now anchored to the installation origin. +- A `room`/`zone` node carries `area_id: Option` so a HomeCore `EntityEntry.area_id` resolves to exactly one WorldGraph node (entity linkage per ADR-127). + +### 1.4 Pipeline Position + +``` + ADR-044 GeoPoint / GeoRegistration (installation origin) + │ pins local ENU frame + ▼ + ADR-136 streaming frames ─► ADR-137 FusionEngine ─► (EvidenceRef, ContradictionFlag) + │ │ + │ person/object/event │ provenance + ▼ ▼ + ADR-113 sensor placement ─► ┌──────────────── WorldGraph ───────────────────┐ + ADR-138 LinkGroup ─► │ nodes: room/zone/wall/doorway/sensor/rf_link/ │ + homecore area_id ─► │ person_track/object_anchor/event/ │ + MAT ScanZone bounds ─► │ semantic_state │ + │ edges: observes/located_in/adjacent_to/ │ + ADR-141 privacy modes ───► │ supports/contradicts/derived_from/ │ + │ privacy_limited_by │ + └───────────────┬───────────────┬───────────────┘ + │ query API │ RVF write-through + ▼ ▼ + observability / location / privacy .rvf bundle (persisted) + rollup queries (ADR-140, ADR-144, + ADR-145 consume) +``` + +The WorldGraph sits *downstream* of fusion (it stores fused beliefs, not raw frames) and *upstream* of the semantic/agent layer (ADR-140) and evaluation harness (ADR-145).

Decision + +### 2.1 Node and Edge Model: serde Enum, Not Trait Objects + +Nodes are a **`#[derive(Serialize, Deserialize)]` enum**, not boxed trait objects. This is the single most consequential decision: a serde enum gives deterministic, schema-versioned, RVF-friendly persistence (every variant serializes to the same wire layout regardless of build), whereas `Box` would require `typetag` (an extra dependency, non-deterministic across crate versions) and could not be field-walked by an evaluation harness.

Where those crates are not yet present, the handles degrade to opaque `String` content-addresses so the WorldGraph compiles and persists independently. + +### 2.2 Graph Container and Bridge + +Following `petgraph_bridge.rs`, the WorldGraph wraps petgraph and exposes a domain API. We use `StableDiGraph` (not `Graph`) because nodes are removed at runtime (a person leaves, a track dies) and stable indices keep `WorldId → NodeIndex` resolution valid. + +```rust +//! v2/crates/wifi-densepose-worldgraph/src/graph.rs + +use petgraph::stable_graph::{StableDiGraph, NodeIndex}; +use std::collections::HashMap; +use crate::model::{WorldNode, WorldEdge, WorldId}; + +pub struct WorldGraph { + inner: StableDiGraph, + /// Stable WorldId -> petgraph handle. Survives removals. + index: HashMap, + /// Installation origin; all ENU coords are relative to this (ADR-044). + registration: wifi_densepose_geo::types::GeoRegistration, + next_id: u64, + schema_version: u16, +} + +impl WorldGraph { + pub fn new(registration: wifi_densepose_geo::types::GeoRegistration) -> Self; + + /// Insert a node, returning its stable WorldId. Allocates the id if the + /// node's embedded id is WorldId(0) (sentinel = "assign me one"). + pub fn upsert_node(&mut self, node: WorldNode) -> WorldId; + + /// Add a typed edge. Errors if either endpoint is unknown. + pub fn add_edge(&mut self, from: WorldId, to: WorldId, edge: WorldEdge) + -> Result<(), WorldGraphError>; + + /// Resolve a HomeCore area_id to its Room node (entity linkage, ADR-127). + pub fn room_for_area(&self, area_id: &str) -> Option; + + pub fn node(&self, id: WorldId) -> Option<&WorldNode>; + pub fn neighbors(&self, id: WorldId) -> impl Iterator; +} +``` + +A `bridge.rs` module mirrors `petgraph_bridge.rs`'s `to_petgraph` / `from_petgraph` so external algorithm code can borrow a plain `&StableDiGraph` for petgraph's `dijkstra`, `connected_components`, etc., without leaking the domain wrapper. + +### 2.3 Provenance: derived_from and contradicts from ADR-137 + +The house rule is honored structurally: **every `SemanticState` node carries a `SemanticProvenance`** and is reachable along `DerivedFrom` edges back to the evidence that produced it. The provenance tuple binds the four required traces: + +```rust +//! Mandatory provenance for every SemanticState (house rule). +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct SemanticProvenance { + /// Signal evidence: ADR-137 EvidenceRef content-address(es). + pub evidence: Vec, + /// Model version that produced this belief. + pub model_version: String, + /// Calibration version (ADR-135 baseline id) in effect. + pub calibration_version: String, + /// Privacy decision (ADR-141 mode + action) under which it was derived. + pub privacy_decision: PrivacyDecisionRef, +} +``` + +When the fusion engine (ADR-137) emits a new `SemanticState`: + +1. `upsert_node()` inserts the new `SemanticState` node. +2. For each `EvidenceRef` in its provenance, the engine adds a `DerivedFrom` edge from the new state to the corresponding `Event` / prior `SemanticState` / `Observes` source. +3. If ADR-137 attached a `ContradictionFlag` (the new belief disagrees with a still-live prior belief), the engine adds a `Contradicts` edge between the two `SemanticState` nodes carrying the flag's magnitude. The prior node is **not deleted** — it is retained so a query can surface the disagreement; a downstream resolver (ADR-140) decides which belief wins. + +This makes node updates *append-with-provenance*: the graph never loses the chain of reasoning, which is exactly what ADR-145's ablation harness needs to attribute a wrong belief to a specific sensor/model/calibration. + +### 2.4 Privacy: privacy_limited_by edges from ADR-141 + +For each `(sensor, observable-node)` pair, the WorldGraph materializes a `PrivacyLimitedBy` edge derived from the ADR-141 privacy mode/action registry. The edge records the limiting `mode`, the `action` evaluated, and whether observation is `allowed` under the current mode. This is computed by a reducer that runs whenever the active privacy mode changes: + +```rust +/// Recompute privacy_limited_by edges for the active mode (ADR-141). +/// For every Observes edge (sensor -> node), evaluate the mode's policy for +/// that sensor's modality + the node kind, and write/update a matching +/// PrivacyLimitedBy edge. +pub fn apply_privacy_mode( + &mut self, + mode: &PrivacyMode, // from ADR-141 control plane +) -> PrivacyRollup; + +/// Result of a privacy-impact rollup query (§2.5). +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct PrivacyRollup { + pub mode: String, + /// Nodes that become unobservable under this mode. + pub suppressed_nodes: Vec, + /// (sensor, node) pairs newly denied. + pub denied_pairs: Vec<(WorldId, WorldId)>, + pub allowed_pairs: usize, +} +``` + +Because `PrivacyLimitedBy` is a first-class edge, "what can sensor X still see under mode Y?" is a one-hop neighbor filter — no separate policy index is needed, and the privacy posture is *visible in the persisted graph* (an auditor can read the `.rvf` and see what was suppressed). + +### 2.5 Query API Surface (v1 Scope) + +The v1 query API is intentionally narrow — three families, all expressible as petgraph traversals over the typed edges: + +```rust +//! v2/crates/wifi-densepose-worldgraph/src/query.rs + +impl WorldGraph { + /// OBSERVABILITY CHAIN: sensor -> all nodes it currently observes. + /// Follows Observes edges (one hop) filtered by current PrivacyLimitedBy. + pub fn observed_by(&self, sensor: WorldId) -> Vec; + + /// LOCATION QUERY: contents of room X. + /// Reverse LocatedIn traversal: all PersonTrack/ObjectAnchor/Event/Zone + /// nodes located_in this room (transitively through child Zones). + pub fn contents_of(&self, room: WorldId) -> RoomContents; + + /// PRIVACY-IMPACT ROLLUP: for a candidate mode, what is suppressed. + /// Pure (does not mutate); ADR-145 uses it to score privacy leakage. + pub fn privacy_impact(&self, mode: &PrivacyMode) -> PrivacyRollup; + + /// ADR-144 anchor accessor: sensors + object anchors with known ENU pos. + pub fn anchors(&self) -> Vec<(WorldId, EnuPoint)>; +} +``` + +**Scope boundary for v1:** the graph models the **current static topology** of a single installation. Temporal reconfiguration history (rooms repartitioned, sensors relocated over weeks) is **deferred to ADR-142** (Evolution Tracker / temporal VoxelMap). The WorldGraph emits a `TopologyChanged` domain event when static structure changes; ADR-142 subscribes and aggregates the history. This keeps the WorldGraph a clean *current-state* projection and avoids baking a time-series store into the graph itself. + +### 2.6 Persistence: RVF Bundle with Async Write-Through + +The graph persists as an **RVF bundle**, reusing the segment-based format already implemented in `v2/crates/wifi-densepose-sensing-server/src/rvf_container.rs` (64-byte aligned segments, `SEG_META` for JSON metadata, `SEG_MANIFEST` for the directory, CRC32 content hashes). No new file format is introduced. + +- **Layout:** one `SEG_META` segment holds the serde-JSON of `{ registration, schema_version, nodes: Vec, edges: Vec<(WorldId, WorldId, WorldEdge)> }`. A `SEG_MANIFEST` segment carries node/edge counts and the schema version. A `SEG_WITNESS` segment carries the SHA-256 of the node+edge payload for the ADR-028 proof chain. +- **Async write-through:** mutations (`upsert_node`, `add_edge`, `apply_privacy_mode`) are applied to the in-memory graph synchronously and enqueued to a bounded `tokio::sync::mpsc` channel drained by a single writer task that coalesces bursts and rewrites the `.rvf` (write-temp-then-rename). The hot path never blocks on disk. This mirrors the `homecore/src/registry.rs` "in-memory now, persistence to a backing store later" staging — except the backing store (RVF) is specified up front. +- **Pinning:** the bundle stores its `GeoRegistration` so a reloaded graph re-establishes the same local ENU frame. `enu_to_wgs84()` (ADR-044) regenerates lat/lon for any node on demand for the map overlay. + +```rust +//! v2/crates/wifi-densepose-worldgraph/src/persist.rs + +pub struct WorldGraphStore { + path: std::path::PathBuf, + tx: tokio::sync::mpsc::Sender, +} + +impl WorldGraphStore { + /// Open or create an RVF-backed store; spawns the write-through task. + pub async fn open(path: impl Into) -> Result<(Self, WorldGraph), WorldGraphError>; + + /// Enqueue a snapshot write (non-blocking, coalesced by the writer task). + pub fn enqueue_snapshot(&self, graph: &WorldGraph) -> Result<(), WorldGraphError>; + + /// Force-flush and await durability (used at shutdown / before witness). + pub async fn flush(&self) -> Result<(), WorldGraphError>; +} +``` + +### 2.7 Error Type and Domain Events + +```rust +#[derive(Debug, thiserror::Error)] +pub enum WorldGraphError { + #[error("unknown node: {0:?}")] + UnknownNode(WorldId), + #[error("edge endpoint type mismatch: {0}")] + EdgeTypeMismatch(String), + #[error("schema version {found} unsupported (expected {expected})")] + SchemaMismatch { found: u16, expected: u16 }, + #[error("RVF (de)serialisation error: {0}")] + Rvf(String), + #[error("privacy mode references unknown action: {0}")] + UnknownPrivacyAction(String), +} + +/// Event-sourced change notifications (per project DDD rule). +#[derive(Clone, Debug, Serialize, Deserialize)] +pub enum WorldGraphEvent { + NodeUpserted(WorldId), + NodeRemoved(WorldId), + EdgeAdded { from: WorldId, to: WorldId }, + TopologyChanged, // consumed by ADR-142 + PrivacyModeApplied(String), // emitted by apply_privacy_mode + ContradictionRecorded { a: WorldId, b: WorldId, magnitude: f32 }, +} +``` + +### 2.8 Interface Boundaries + +| Boundary | This crate provides | This crate consumes | +|----------|---------------------|---------------------| +| ADR-044 `wifi-densepose-geo` | — | `GeoRegistration`, `GeoPoint`, `wgs84_to_enu`/`enu_to_wgs84` | +| ADR-127 `homecore/registry.rs` | `room_for_area(area_id)` | `EntityEntry.area_id`, `EntityEntry.device_id` (join keys) | +| MAT `scan_zone.rs` | `ZoneBoundsEnu`, `Sensor` node | `ZoneBounds`, `SensorPosition` shapes (reprojected to ENU) | +| ADR-137 fusion | `DerivedFrom`/`Contradicts` edges, `SemanticState` nodes | `EvidenceRef`, `ContradictionFlag` | +| ADR-141 privacy | `apply_privacy_mode`, `privacy_impact` | `PrivacyMode`, action registry | +| ADR-138 LinkGroup | `RfLink.link_group_id` field | LinkGroup ids | +| ADR-142 evolution | `WorldGraphEvent::TopologyChanged` stream | — | +| ADR-144 UWB | `anchors()` accessor | — | +| ADR-145 ablation | `privacy_impact()`, provenance chains | — | + +The crate must compile **standalone**: where ADR-137/141 types are not yet present, their handles are `String` content-addresses (feature-gated `full-fusion` swaps them for the real types). This keeps `wifi-densepose-worldgraph` a no-internal-dep leaf on `wifi-densepose-geo` only, matching the publishing-order discipline in CLAUDE.md. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **One spatial identity space.** `area_id` (HomeCore), `ScanZone` (MAT), and sensor placement (ADR-113) finally resolve to one node set. `room_for_area()` is the single join. +- **Provenance is structural, not bolted on.** Every belief traces to signal evidence + model version + calibration version + privacy decision via `SemanticProvenance` and `DerivedFrom` edges — the house rule is enforced by the type system, not by convention. +- **Privacy posture is auditable.** `PrivacyLimitedBy` edges live in the persisted `.rvf`, so an auditor can read what each mode suppressed without re-running the system. +- **Deterministic persistence.** The serde-enum-over-RVF choice produces byte-stable snapshots suitable for the ADR-028 witness proof chain (SHA-256 of the node/edge payload). +- **Reuses proven mechanics.** The petgraph bridge pattern (`ruv-neural-graph`) and the RVF container (`sensing-server`) are existing, tested code — no new graph engine or file format. +- **Unblocks four downstream ADRs.** ADR-140 (semantic records anchor to `SemanticState` nodes), ADR-142 (consumes `TopologyChanged`), ADR-144 (consumes `anchors()`), ADR-145 (scores over `privacy_impact()` + provenance). + +### 3.2 Negative + +- **New crate to maintain.** `wifi-densepose-worldgraph` adds a 16th workspace crate and an entry to the publishing order (leaf on `wifi-densepose-geo`). +- **Cross-crate handle coupling.** The full-fidelity provenance/privacy edges depend on ADR-137/141 types. Until those land, the `String`-handle fallback means provenance is content-addressed but not yet richly typed — a temporary loss of compile-time guarantees. +- **Snapshot-rewrite cost.** Async write-through rewrites the whole `.rvf` on flush rather than appending a delta. For a single-installation graph (hundreds of nodes, low-Hz mutation) this is sub-millisecond, but it does not scale to thousands of installations in one file (out of scope — one bundle per installation). +- **No history in v1.** Querying "where was the sofa last month" requires ADR-142; the WorldGraph alone answers only "now." + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Stale `petgraph` `NodeIndex` after node removal | Medium | Dangling edge / panic | Use `StableDiGraph` (indices survive removal) and the `WorldId → NodeIndex` map; never expose raw `NodeIndex` across the API boundary | +| Schema drift breaks old `.rvf` bundles | Medium | Reload failure | `schema_version` in `SEG_MANIFEST`; `WorldGraphError::SchemaMismatch` with an explicit migration path; refuse-and-warn rather than mis-parse | +| Contradiction edges accumulate without resolution | Medium | Graph bloat, ambiguous beliefs | A retention policy prunes `Contradicts` edges whose losing `SemanticState` has `valid_from` older than a TTL once ADR-140's resolver has chosen a winner | +| Privacy edge recompute lags a fast mode switch | Low | Brief window of stale `allowed` flags | `apply_privacy_mode` runs synchronously on the mutation path before any new `Observes` edge is honored; rollup returned to caller for confirmation | +| ENU origin re-pinned after partial population | Low | Coordinate frame mismatch | Origin is immutable after `WorldGraph::new`; re-pinning requires a new bundle + ADR-142 migration event | + +--- + +## 4. Alternatives Considered + +### 4.1 Trait-Object Nodes (`Box`) + +Rejected. `typetag`-style polymorphic serde is non-deterministic across crate/serde versions, cannot be field-walked by ADR-145's harness, and breaks the byte-stable witness proof. The serde enum gives closed-world exhaustiveness (the compiler forces every query to handle every node kind) and deterministic bytes. The `petgraph_bridge.rs` precedent already stores concrete weights, not trait objects. + +### 4.2 Extend `GeoScene` with Interior Features + +Rejected. `geo::types::GeoScene` is a WGS84 outdoor scene (buildings/roads from OSM). Bolting rooms/sensors/people onto it would (a) conflate the global frame with the local ENU frame, (b) force the geo crate to depend on fusion/privacy types it has no business knowing, and (c) provide no edges. We *reuse* `GeoRegistration` and the ENU transforms from geo, but the WorldGraph is a separate concern. + +### 4.3 Reuse `homecore` Area Registry Directly + +Rejected as the home. `EntityEntry.area_id` is an opaque string with no geometry and no adjacency; HomeCore's job is HA-compatible entity bookkeeping, not spatial reasoning. The WorldGraph *links to* `area_id` (so automations and sensing share identity) but owns geometry, sensors, and the typed-edge topology HomeCore deliberately does not model. + +### 4.4 A Relational/SQLite Store with Join Tables + +Rejected for v1. Edges-as-rows + recursive CTEs can express the same queries, but (a) the workspace already standardizes on RVF for portable, witness-hashable artifacts, (b) petgraph gives shortest-path/connectivity algorithms for free (observability chains, adjacency reachability) that would be hand-rolled SQL, and (c) an embedded SQLite file is not byte-stable for the proof chain. RVF + petgraph matches existing patterns; a SQL backend remains a future option behind `WorldGraphStore` if scale demands it. + +### 4.5 Temporal Graph from Day One + +Rejected for v1. A bitemporal graph (valid-time + transaction-time on every node/edge) is the correct long-term model, but it doubles the schema complexity and the persistence size before any consumer needs history. v1 ships current-state-only and emits `TopologyChanged`; ADR-142 builds the temporal aggregation on top. This keeps the first deliverable small and the query API simple. + +--- + +## 5. Testing / Acceptance + +### 5.1 Unit Tests (CI, no hardware) + +**T1 — Node/edge round-trip determinism.** Build a graph with one of every `WorldNode` variant and one of every `WorldEdge` variant. Serialize to RVF bytes, deserialize, assert structural equality and assert the SHA-256 of the node/edge payload is byte-stable across two independent serializations (deterministic-persistence acceptance). + +**T2 — `room_for_area` entity linkage.** Insert a `Room { area_id: Some("living_room") }`; assert `room_for_area("living_room")` returns its `WorldId` and `room_for_area("garage")` returns `None`. Mirrors the HomeCore `registry.rs` register-and-read test. + +**T3 — ENU pinning round-trip.** Pin a graph to `GeoRegistration { origin: lat/lon }`; place a `Sensor` at a known `EnuPoint`; reproject to WGS84 via `enu_to_wgs84` and back via `wgs84_to_enu`; assert agreement within 1e-6 m (validates the ADR-044 frame reuse). + +**T4 — Observability chain.** Sensor S observes nodes A,B,C (three `Observes` edges); assert `observed_by(S)` returns exactly {A,B,C}. + +**T5 — Location query (transitive).** Room R contains Zone Z; PersonTrack P `located_in` Z. Assert `contents_of(R)` includes P (transitive through the child zone) and Object/Event nodes located directly in R. + +**T6 — Provenance chain (house rule).** Insert a `SemanticState` with `SemanticProvenance { evidence, model_version, calibration_version, privacy_decision }` and `DerivedFrom` edges to two `Event` sources. Assert every `SemanticState` in the graph has non-empty `evidence`, a `model_version`, a `calibration_version`, and a `privacy_decision` (acceptance: the four-fold trace is present on every belief node). + +**T7 — Contradiction retention.** Insert belief B1, then a contradicting belief B2 (ADR-137 `ContradictionFlag`). Assert a `Contradicts` edge exists, B1 is **not** removed, and a `WorldGraphEvent::ContradictionRecorded` was emitted. + +**T8 — Privacy-impact rollup.** With sensor S observing person P, apply a `PrivacyMode` that denies person observation for S's modality. Assert `privacy_impact(mode).suppressed_nodes` contains P, a `PrivacyLimitedBy { allowed: false }` edge is written, and `observed_by(S)` no longer returns P. + +**T9 — Schema-mismatch refusal.** Hand-craft an RVF `SEG_MANIFEST` with `schema_version = 999`; assert `open()` returns `WorldGraphError::SchemaMismatch` (refuse, do not mis-parse). + +**T10 — Stable index after removal.** Insert 5 nodes, remove the middle one, add a 6th; assert all surviving `WorldId → WorldNode` lookups still resolve and no edge dangles (validates `StableDiGraph` choice). + +### 5.2 Async Persistence Test + +**T11 — Write-through coalescing.** Open a `WorldGraphStore`, enqueue 1,000 rapid snapshots, `flush()`, reopen the bundle, assert the final state matches the last snapshot and that the writer task coalesced (write count < enqueue count). Hot-path `enqueue_snapshot` must not block (assert it returns within a tight bound while the disk write is in flight). + +### 5.3 Witness / Proof (ADR-028 chain) + +Add rows to `docs/WITNESS-LOG-028.md`: + +| Row | Capability | Evidence | Hash | +|-----|-----------|----------|------| +| W-39 | WorldGraph RVF round-trip determinism | `cargo test worldgraph::tests::roundtrip_determinism` | SHA-256 of node/edge payload | +| W-40 | Provenance four-fold trace present on every SemanticState | `cargo test worldgraph::tests::provenance_complete` | SHA-256 of test binary | +| W-41 | Privacy rollup suppresses denied nodes | `cargo test worldgraph::tests::privacy_rollup` | SHA-256 of rollup output | + +`source-hashes.txt` in the witness bundle gains `SHA-256(worldgraph/model.rs)` and `SHA-256(worldgraph/graph.rs)`. + +### 5.4 Acceptance Criteria (Definition of Done) + +1. `wifi-densepose-worldgraph` compiles standalone (`cargo check -p wifi-densepose-worldgraph --no-default-features`) depending only on `wifi-densepose-geo` + `petgraph` + `serde`. +2.

Every `SemanticState` node carries the four-fold provenance trace (signal evidence + model version + calibration version + privacy decision) — enforced by T6 and by the non-`Option` `SemanticProvenance` field. +4. A persisted `.rvf` bundle reloads to a structurally identical graph and re-establishes the same ENU origin. +5.

Context + +### 1.1 The Gap + +The HA-MIND semantic primitive layer landed under ADR-115 §3.12 and lives in `v2/crates/wifi-densepose-sensing-server/src/semantic/`. It is a real, tested, ten-primitive inference layer: `bus.rs` owns a `SemanticBus` that dispatches one `RawSnapshot` to each of ten FSMs (`sleeping`, `distress`, `room_active`, `elderly_anomaly`, `meeting`, `bathroom`, `fall_risk`, `bed_exit`, `no_movement`, `multi_room`) and collects `SemanticEvent`s. Each `SemanticEvent` carries exactly four fields (`bus.rs:44-50`): + +```rust +pub struct SemanticEvent { + pub kind: SemanticKind, + pub state: PrimitiveState, + pub node_id: String, + pub timestamp_ms: i64, +} +``` + +and `PrimitiveState` (`common.rs:36-47`) is one of `Boolean { active, changed, reason }`, `Scalar { value, reason }`, `Event { event_type, reason }`, or `Idle`. The only provenance a downstream consumer receives today is the `Reason` tag list (`common.rs:50-65`) — a `Vec` of human-readable debug strings such as `["motion<5%", "br=12bpm"]`. + +That is the gap this ADR closes. Searching the workspace confirms three concrete absences: + +- **No version provenance on a published state.** Grepping `v2/crates/` for `model_version` and `calibration_version` finds matches only in `wifi-densepose-bfld` and `wifi-densepose-signal` (frame-level metadata), never in the `semantic/` module. A `SemanticEvent` for `fall_risk_elevated` carries no record of *which* model or *which* empty-room baseline (ADR-135) produced it. A caregiver-escalation automation acting on that event cannot audit whether the signal came from a calibrated node or a stale one. +- **No `evidence_refs`, `confidence`, `expiry_at`, or `privacy_action` on a state.** `SemanticEvent` has no field tying its assertion back to the signal evidence that justified it, no machine-readable confidence (only the `Reason` tag strings), no time-to-live, and no privacy classification. `PrimitiveConfig` (`common.rs:71-100`) holds per-primitive thresholds but no per-primitive model/calibration metadata, and `Default` (`common.rs:102-122`) hardcodes them — there is no manifest load path. +- **No `Rest`/inactivity `SemanticKind`.** The `SemanticKind` enum (`bus.rs:29-41`) has ten variants. Inactivity is currently expressed only through `NoMovement` (`no_movement.rs`), which fires a *safety* signal (`presence == true` AND motion < 0.01 for ≥ 30 min — a possible-collapse alarm), and `ElderlyInactivityAnomaly`. Neither expresses the benign, expected state of a person at rest (reading, watching TV). Automations that want to *suppress* lighting/HVAC changes during rest have no primitive to subscribe to; they must reverse-engineer it from the absence of `RoomActive`, which is fragile. + +The privacy boundary is likewise under-specified at the state layer. `mqtt/privacy.rs` makes a binary `PublishDecision::{Publish, Suppress}` keyed solely on `EntityKind::is_biometric()` and a global `--privacy-mode` flag (`privacy.rs:33-39`). Semantic primitives are always `Publish` in that path (`privacy.rs:84-102`) because they are inferred states, not raw biometrics. But there is no per-record privacy *action* — no way to say "publish this `BathroomOccupied` state but anonymize the room", or "strip the biometric attributes from this `PossibleDistress` while keeping the boolean". The privacy decision is made once, globally, at the wire boundary, and is invisible to the record itself. + +Finally, the **Ruflo agent bridge** exists only as a P1 stub. `homecore-assist/src/runner.rs` defines the `RufloRunner` trait and a `NoopRunner` that returns an empty `RufloResponse` (`runner.rs:113-139`); the crate doc (`lib.rs:24-27`) explicitly defers the real subprocess runner and semantic embedding recognizer to P2/P3. There is no path today by which a `SemanticEvent` (or a *combination* of them) reaches a Ruflo agent so that an automation can route on **multi-signal agreement** — e.g. `fall_risk_elevated` AND `elderly_inactivity_anomaly` together escalating to a caregiver, which neither primitive can decide alone. + +### 1.2 What "Semantic State Record" Means Here + +A `SemanticStateRecord` is the unified, versioned, auditable envelope that every primitive emits *instead of* the bare `SemanticEvent`. It is the inference-layer analogue of what ADR-136 calls a `FrameMeta` at the signal layer and what ADR-137 calls an evidence-scored fusion output: a state assertion that carries its own provenance. It captures: + +- **What** was asserted: the `SemanticKind`, the `PrimitiveState`, the `room`, and the `Reason` tags. +- **How confident**: a normalized `confidence ∈ [0, 1]` distinct from the human `Reason` tags. +- **From which model and calibration**: `model_version` and `calibration_version`, threaded from the ADR-136 `FrameMeta` of the frames that produced the snapshot. +- **Backed by what evidence**: `evidence_refs`, opaque handles into the ADR-137 fusion evidence store (and, where relevant, the ADR-139 WorldGraph node IDs). +- **For how long it is valid**: `expiry_at` — the wall-clock instant past which the record must not be acted upon without refresh. +- **Under what privacy classification**: `privacy_action`, an enum that *the record carries*, enforced downstream at the MQTT/Matter boundary. + +What a `SemanticStateRecord` is **not**: it is not a replacement for the per-primitive FSMs, the `Reason` explainability contract, or the existing `--privacy-mode` wire filter. It is the schema that wraps their output so the rest of the system (HOMECORE state machine, automation engine, Ruflo agents, the recorder) can reason about provenance. + +### 1.3 The Provenance Rule + +This ADR honours the project-wide rule that **every semantic state traces to signal evidence + model version + calibration version + privacy decision.** Today a `SemanticEvent` honours none of those four. After this ADR, a `SemanticStateRecord` carries all four as first-class fields, and the witness/proof chain (ADR-028 style) can assert that no record reaches an HA controller without them. + +### 1.4 Pipeline Position + +``` +CSI frames (per node) + → signal pipeline → FrameMeta { model_version, calibration_version } (ADR-136) + → fusion engine → quality score + evidence_refs (ADR-137) + → RawSnapshot (semantic/common.rs) ← unchanged projection + → SemanticBus::tick() ← still runs 10+1 FSMs + → SemanticStateRecord::from_event(meta, ev) ← NEW: wraps each SemanticEvent + carries model_version, calibration_version, confidence, + room, evidence_refs, expiry_at, privacy_action + ├─→ MQTT / Matter publisher → privacy_action enforced at boundary (ADR-141 maps mode→action) + ├─→ HOMECORE StateMachine::set() → state_changed broadcast (ADR-127) + │ → AutomationEngine triggers (ADR-129) + └─→ SemanticAgentBridge::route() ← NEW: feeds agreeing records to Ruflo (ADR-133) + → RufloRunner::send_request() → caregiver escalation / multi-signal automation +``` + +The `SemanticBus` is unchanged except that `tick()` returns records instead of bare events; the FSMs themselves do not move.

Replacing it outright would churn those tests. Instead, `SemanticEvent` becomes the *inner* assertion and `SemanticStateRecord` the *outer* envelope; the bus constructs records, and a `record.as_event()` accessor reproduces the old four-field shape for any caller that has not migrated. The proptest invariants are preserved verbatim and a new invariant — "every record carries a non-empty `model_version` and `calibration_version`" — is added. + +### 2.2 Constructing a Record: `from_event` + +The bus does not change the FSMs. It changes the assembly step in `SemanticBus::tick()` (`bus.rs:86-111`): the `filter_map` that builds `SemanticEvent`s now builds `SemanticStateRecord`s. + +```rust +impl SemanticStateRecord { + /// Wrap one primitive's event with the provenance from the frame + /// metadata that produced the snapshot. + pub fn from_event( + ev: SemanticEvent, + meta: &SnapshotMeta, // see §2.6 — threaded with RawSnapshot + cfg: &PrimitiveConfig, + ) -> Self { + let ttl = cfg.record_ttl(ev.kind); // §2.4 + Self { + kind: ev.kind, + state: ev.state, + node_id: ev.node_id, + timestamp_ms: ev.timestamp_ms, + room: meta.room.clone(), + confidence: meta.confidence_for(ev.kind), // §2.6 + model_version: meta.model_version.clone(), + calibration_version: meta.calibration_version.clone(), + evidence_refs: meta.evidence_refs.clone(), + expiry_at: meta.captured_at + ttl, + privacy_action: cfg.privacy_action_for(ev.kind), + } + } + + /// Reproduce the legacy four-field event for un-migrated callers. + pub fn as_event(&self) -> SemanticEvent { + SemanticEvent { + kind: self.kind, + state: self.state.clone(), + node_id: self.node_id.clone(), + timestamp_ms: self.timestamp_ms, + } + } +} +``` + +`SnapshotMeta` is a small companion struct attached to each `RawSnapshot` carrying `model_version`, `calibration_version`, `evidence_refs`, `room`, `captured_at: SystemTime`, and the per-kind confidence inputs. It is populated by the snapshot projection step that already builds `RawSnapshot` from the `VitalsSnapshot` + `sensing_update` broadcast (`common.rs:5-33`). When the upstream frame metadata is absent (e.g. a synthetic test snapshot), `SnapshotMeta::unknown()` supplies `model_version = "unknown"`, `calibration_version = "uncalibrated"`, empty `evidence_refs`, and `confidence = 1.0` for deterministic FSM transitions — so existing tests that build a bare `RawSnapshot::default()` still pass. + +### 2.3 `privacy_action` Semantics and the Boundary Contract + +The record carries `privacy_action`, but the record layer **does not** redact anything. Redaction is enforced exactly where it is today — in `mqtt/privacy.rs` at the wire boundary — extended from a binary decision to one keyed on the record's action: + +```rust +pub enum PublishDecision { + Publish, // unchanged: send verbatim + Suppress, // unchanged: drop silently + Redact(PrivacyAction), // NEW: send, but apply the action's transform +} + +pub fn decide_record(rec: &SemanticStateRecord, mode_default: bool) -> PublishDecision { + match rec.privacy_action { + PrivacyAction::Allow => PublishDecision::Publish, + PrivacyAction::AnonymizeByRoom => PublishDecision::Redact(PrivacyAction::AnonymizeByRoom), + PrivacyAction::StripBiometrics => PublishDecision::Redact(PrivacyAction::StripBiometrics), + } +} +``` + +The existing biometric `EntityKind` filter (`privacy.rs:33-39`) is unchanged and runs first: raw HR/BR/pose entities are still `Suppress`ed under global `--privacy-mode`. The new `decide_record` path applies *only* to `SemanticStateRecord`s, which were never biometric and were always `Publish` (`privacy.rs:84-102`). The record's action therefore adds granularity *within* the always-published semantic class — it cannot weaken the existing global biometric suppression. + +**The mode→action mapping is explicitly delegated to ADR-141.** This ADR defines the *action vocabulary* (`Allow`/`AnonymizeByRoom`/`StripBiometrics`) and the enforcement point. ADR-141 (BFLD Privacy Control Plane) owns the named privacy *modes* and the policy that maps a deployment's mode plus the primitive kind onto one of these actions — and the runtime attestation that the mapping was applied. `PrimitiveConfig::privacy_action_for(kind)` is the seam: in this ADR it returns a static default (`Allow` for all kinds, preserving today's behaviour); ADR-141 replaces the seam with its policy engine without re-touching the record schema. + +### 2.4 Per-Kind TTL and `expiry_at` + +`expiry_at` is computed as the record's `captured_at` plus a per-kind TTL drawn from `PrimitiveConfig`. The TTLs reflect each primitive's physical timescale, not a single global value, because acting on a stale `bed_exit` (a one-shot event) is very different from acting on a stale `someone_sleeping` (a sustained state). + +| Kind | TTL | Rationale | +|------|-----|-----------| +| `BedExit`, `MultiRoom`, `FallRisk` (event) | 30 s | One-shot events; a consumer that acts more than 30 s late is acting on history, not state. | +| `RoomActive`, `BathroomOccupied`, `Rest` | 90 s | Occupancy states refresh on the 30 s `room_active_window`; 3× window before considered stale. | +| `SomeoneSleeping`, `NoMovement` | 10 min | Slow-changing states; the FSM dwell is minutes-to-hours. | +| `PossibleDistress`, `ElderlyAnomaly` | 5 min | Safety states; short enough that a missed refresh self-clears rather than persisting a false alarm. | +| `FallRisk` (scalar) | 5 min | Continuous score; recomputed every tick, so a 5 min TTL is generous. | + +`record_ttl(kind)` returns these as `Duration`s; the values are config fields with the table above as `Default`. A consumer that reads a record past `expiry_at` MUST treat it as "unknown", not as the last asserted value — this is the contract the HOMECORE state machine and the automation engine rely on to avoid acting on stale safety states after a sensor outage. + +### 2.5 The `Rest` Primitive — an Explicit v2 `SemanticKind` + +The `SemanticKind` enum (`bus.rs:29-41`) gains one variant in this ADR: + +```rust +pub enum SemanticKind { + SomeoneSleeping, PossibleDistress, RoomActive, ElderlyAnomaly, + Meeting, BathroomOccupied, FallRisk, BedExit, NoMovement, MultiRoom, + Rest, // NEW (v2) +} +``` + +`Rest` is the benign, expected inactivity state of a present, awake person (reading, watching TV): `presence == true` AND `motion < room_active_motion_threshold` AND NOT `someone_sleeping` AND breathing rate present and in the awake band, sustained for a dwell. It is added as a new primitive file `semantic/rest.rs` with its own FSM and tests, registered in the bus exactly as the existing ten are (one file change per the §3.12.6 "adding a primitive is one file change" contract documented in `mod.rs:18-22`). + +**Why not alias `no_movement`.** `NoMovement` (`no_movement.rs`) is a *safety* primitive: it fires after 30 minutes of near-zero motion as a possible-collapse alarm, and the project doc (`no_movement.rs:1-6`) frames it that way. Aliasing `Rest` to it would conflate "person resting comfortably" with "person possibly collapsed" — the exact distinction caregivers need. `Rest` has a *shorter* dwell, a *higher* motion ceiling, and an explicit "awake breathing" gate, and crucially it carries the opposite automation intent: `Rest` should *suppress* environmental changes (don't turn the lights off on someone reading), whereas `NoMovement` should *escalate*. They are different states with different downstream consumers and must be different `SemanticKind`s. + +**Deferral.** The remaining proposed v2 primitives — `child-play`, `pet-vs-human`, `agitation-gradient`, `circadian-phase` — are explicitly deferred to a follow-on ADR. They each require new signal inputs not present in `RawSnapshot` today (per-person classification embeddings, multi-day circadian baselines persisted across restart). `Rest` is the only v2 primitive that can be built from the existing `RawSnapshot` fields, so it is the only one promoted here. + +### 2.6 Confidence Derivation and the Manifest + +`confidence ∈ [0,1]` is per-record and per-kind. The rule: + +1. A deterministic FSM transition that used only `RawSnapshot` scalars (e.g. `bed_exit` time-gate crossing) yields `confidence = 1.0` — the FSM is exact given its inputs. +2. When the producing snapshot carried an ADR-137 fusion quality score (degraded link, contradiction flag), `confidence` is the product of `1.0` and that fusion score, clamped to `[0,1]`. A `BathroomOccupied` derived from a node whose fusion score was 0.6 yields `confidence = 0.6`. +3. When the snapshot was produced on an `"uncalibrated"` node (no ADR-135 baseline), confidence is capped at `0.8` to flag that motion/amplitude thresholds were absolute rather than baseline-relative. + +`PrimitiveConfig` is extended to load per-primitive **model/calibration metadata from a manifest**, so that the `model_version` and `calibration_version` stamped onto every record are auditable rather than hardcoded. Today `PrimitiveConfig::default()` hardcodes thresholds (`common.rs:102-122`); this ADR adds an optional manifest: + +```rust +/// Loaded once at startup from `--semantic-manifest-file` (TOML). Maps a +/// model/calibration identity onto each primitive so records are auditable. +#[derive(Debug, Clone, Default)] +pub struct PrimitiveManifest { + /// e.g. "ha-mind-v2.1" — the semantic-layer model bundle version. + pub model_version: String, + /// Build commit hash of the sensing-server that produced records. + pub commit_hash: String, + /// ISO-8601 date the model bundle was trained/released. + pub model_date: String, + /// Per-node calibration versions, keyed by node_id, from ADR-135 + /// baseline files.

The motivating case: `FallRisk` (elevated) AND `ElderlyAnomaly` (firing) within a short window in the same room ⇒ caregiver escalation. `fall_risk.rs` cannot see `elderly_anomaly`'s state, and vice versa; only an aggregator over records can. + +The bridge is a new component, `SemanticAgentBridge`, in `homecore-assist` (alongside the existing `RufloRunner` trait in `runner.rs`). It does **not** replace the voice/intent pipeline — it reuses the same `RufloRunner` subprocess transport. + +```rust +/// Subscribes to the SemanticStateRecord stream and routes agreeing +/// records to a Ruflo agent for multi-signal automation decisions. +/// Reuses the existing RufloRunner transport (homecore-assist/runner.rs). +pub struct SemanticAgentBridge { + runner: R, + rules: Vec, + /// Sliding window of recent records per (room, kind). + recent: RecordWindow, +} + +/// A multi-signal agreement that, when satisfied, sends a payload to the +/// agent.

This is the project provenance rule applied to the agent boundary: the agent never sees a bare "fall risk is high" — it sees "fall risk is high, confidence 0.82, model ha-mind-v2.1, node esp32s3-com9 calibrated baseline-2026-05-28, evidence fusion#clip-1841." An agent declining or confirming an escalation does so against an auditable record. + +**P1/P2 staging.** With the existing `NoopRunner` (`runner.rs:113-139`), `route()` returns `Ok(None)` and the bridge falls back to a deterministic local decision (fire the escalation event directly into the HOMECORE state machine). When the real subprocess `RufloRunner` lands (ADR-133 P2, `runner.rs:9-18` deferral), `route()` consults the agent. The bridge is written against the trait, so no bridge code changes when the runner is swapped — mirroring how the assist pipeline already swaps `NoopRunner` for the real runner. + +### 2.8 Bridge to HOMECORE State Machine + +`SemanticStateRecord`s also flow into the HOMECORE `StateMachine` (`homecore/src/state.rs`) so that ADR-129 automations can trigger on them via the existing `state_changed` broadcast. The mapping: + +- Each record becomes a `StateMachine::set(entity_id, state, attributes, context)` call (`state.rs:75-110`). The `entity_id` is `binary_sensor._` (or `sensor.` for `FallRisk`), matching the HA entity naming the MQTT discovery already uses. +- The record's provenance (`model_version`, `calibration_version`, `confidence`, `expiry_at`, `privacy_action`, `evidence_refs`) is serialized into the `attributes: serde_json::Value` so it survives into the `StateChangedEvent` (`event.rs:101-106`) and is queryable by automations and the recorder. +- The `Context` (`event.rs:42-69`) is stamped with the bridge as origin so automations can detect and avoid self-trigger loops, exactly as HA's context does. + +The HOMECORE state machine already suppresses no-op writes (`state.rs:92-99`); a record whose `state` and `attributes` are unchanged from the prior write does not re-fire the broadcast, so a primitive emitting the same `Scalar` confidence every tick does not spam the channel. A record's `expiry_at` is written into attributes; a consumer reading state past that instant treats it as `unknown` (§2.4). + +### 2.9 Interface Boundaries (Summary) + +| Boundary | Type crossing it | Owner | +|----------|------------------|-------| +| signal → semantic | `RawSnapshot` + `SnapshotMeta` (model/calibration/evidence) | `semantic/common.rs` (ADR-136 supplies meta) | +| semantic bus output | `SemanticStateRecord` | `semantic/bus.rs` (this ADR) | +| semantic → MQTT/Matter | `SemanticStateRecord` → `PublishDecision` | `mqtt/privacy.rs` (this ADR; mapping by ADR-141) | +| semantic → HOMECORE | `SemanticStateRecord` → `StateMachine::set` | `homecore/src/state.rs` (this ADR) | +| semantic → Ruflo | agreeing records → JSON payload → `RufloRunner::send_request` | `homecore-assist` `SemanticAgentBridge` (this ADR; transport from ADR-133) | +| legacy callers | `SemanticStateRecord::as_event()` → `SemanticEvent` | back-compat shim (this ADR) | + +### 2.10 Test Plan + +**Tier 1 — Record construction is total (unit test, `common.rs`).** For every `SemanticKind` variant (now 11 including `Rest`) and every non-`Idle` `PrimitiveState`, `SemanticStateRecord::from_event` produces a record with a non-empty `model_version`, non-empty `calibration_version`, a finite `confidence ∈ [0,1]`, and an `expiry_at > timestamp`. Assert `as_event()` round-trips the four legacy fields exactly. + +**Tier 2 — Provenance proptest (extend `bus.rs` proptest suite).** Reuse the existing `arb_snapshot()` strategy. Assert a new invariant alongside the existing ones (`bus_events_carry_node_id_and_ts`, `boolean_states_always_have_reason_tags`): **every emitted `SemanticStateRecord` carries a non-empty `model_version` and `calibration_version`**, and `confidence` is in `[0,1]`. This wires the provenance rule into the property suite that already guards the bus. + +**Tier 3 — Default behaviour unchanged (unit test).** With `PrimitiveManifest::default()` and `privacy_action_for` returning `Allow`, assert `decide_record` returns `Publish` for all 11 kinds — i.e. zero observable change from today's `privacy.rs:84-102` behaviour. This is the no-regression gate. + +**Tier 4 — `Rest` distinct from `NoMovement` (unit test, `rest.rs`).** Feed a sequence: present, awake breathing (br ≈ 14 bpm), motion 0.05 for 3 minutes. Assert `Rest` fires `Boolean { active: true }` and `NoMovement` stays `Idle` (its 30-min dwell is not met and motion ≥ 0.01). Then drop motion to 0.005 for 30 minutes and assert `NoMovement` fires while `Rest` exits — proving the two states are not aliases. + +**Tier 5 — TTL / staleness (unit test).** Build a `FallRisk` event record and a `SomeoneSleeping` record. Assert `expiry_at - captured_at == 30 s` and `10 min` respectively (per §2.4 table). Assert a helper `record.is_expired(now)` returns `true` past `expiry_at`. + +**Tier 6 — `privacy_action` enforcement (unit test, `mqtt/privacy.rs`).** For a record with `privacy_action = AnonymizeByRoom`, assert `decide_record` returns `Redact(AnonymizeByRoom)` and that the redaction transform replaces `room = "bedroom"` with a coarse bucket. For `StripBiometrics`, assert HR/BR-derived `Reason` tags and `evidence_refs` are removed while the boolean state survives. For `Allow`, verbatim publish. + +**Tier 7 — Multi-signal agreement bridge (async unit test, `homecore-assist`).** With a `NoopRunner`, feed a `FallRisk` record then an `ElderlyAnomaly` record for the same room within 120 s, both `confidence ≥ 0.7`. Assert `route()` recognises the `caregiver_escalation` rule and (since the runner is a no-op) falls back to firing the escalation locally. Feed the same two records > 120 s apart and assert no escalation. Feed them in *different* rooms and assert no escalation. + +**Tier 8 — HOMECORE state-machine bridge (async unit test).** Route a record into a `StateMachine`; subscribe; assert a `StateChangedEvent` (`event.rs:101-106`) fires whose `new_state` attributes contain `model_version`, `calibration_version`, `confidence`, and `expiry_at`.

Consequences + +### 3.1 Positive + +- **Auditable states.** Every published semantic state now traces to a model version, a calibration version, signal evidence, and a privacy decision. A caregiver-escalation automation can refuse to act on records from an `"uncalibrated"` node, closing the silent-degradation hole where an uncalibrated node's absolute thresholds produced unreliable states with no flag. +- **Privacy granularity without weakening the existing guarantee.** The `privacy_action` enum adds room-anonymization and biometric-stripping *within* the always-published semantic class, while the existing global biometric `Suppress` filter (`privacy.rs`) is untouched and still runs first. Healthcare deployments gain `StripBiometrics` per-record without a new wire schema. +- **Multi-signal automations become possible.** The agent bridge enables decisions no single primitive can make (`fall_risk` + `elderly_anomaly` → caregiver), reusing the existing `RufloRunner` transport rather than inventing a new IPC path. +- **`Rest` unblocks suppression automations.** Automations can finally subscribe to "person resting comfortably" and suppress environmental changes, instead of fragilely inferring it from the absence of `RoomActive`. +- **Back-compatible.** `SemanticEvent` is preserved as the inner type; `as_event()` and `PrimitiveManifest::default()` mean un-migrated callers and existing tests observe no behaviour change. + +### 3.2 Negative + +- **Larger records on the wire.** A `SemanticStateRecord` carries five new fields plus `evidence_refs`. For high-rate `Scalar` primitives (`fall_risk` publishes every tick) this is more bytes; the HOMECORE no-op suppression (`state.rs:92-99`) and the per-kind TTL mitigate the rate, but MQTT payloads grow. +- **Manifest is a new operational artifact.** Operators must supply `--semantic-manifest-file` to get meaningful `model_version`/`calibration_version`; absent it, every node is stamped `"uncalibrated"`. This is not a regression (today there is no version at all) but it is a new step to get full auditability. +- **Bridge couples two crates.** `homecore-assist` now depends on the `SemanticStateRecord` type from the sensing server. The dependency is one-directional (assist depends on the semantic schema, not vice versa) and the schema is small, but it is a new cross-crate edge. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Confidence derivation is gamed by always returning 1.0 | Medium | Records look more trustworthy than they are; uncalibrated nodes' states acted on blindly | §2.6 caps confidence at 0.8 on `"uncalibrated"` nodes and multiplies by the ADR-137 fusion score; Tier 2 proptest asserts `confidence ∈ [0,1]` but a separate review must confirm the per-kind derivation is honest | +| Agreement rule fires on coincidental co-occurrence | Medium | Spurious caregiver escalation | `min_confidence` gate + same-room scoping + 120 s window; the agent (when present) makes the final call with full provenance, declining low-evidence escalations | +| `expiry_at` consumers ignore it and act on stale safety states | Low | Acting on a post-outage stale `possible_distress` | The contract is documented (§2.4) and the HOMECORE attributes carry `expiry_at`; Tier 5 tests `is_expired`; recorder can flag consumers that read past expiry | +| ADR-141 mode→action mapping not yet built; `privacy_action` defaults to `Allow` everywhere | High (until ADR-141 lands) | No room-anonymization until the policy engine ships | `privacy_action_for` seam returns `Allow` (today's behaviour) until ADR-141 replaces it; no record-schema change needed when it does | + +--- + +## 4. Alternatives Considered + +### 4.1 Extend `SemanticEvent` In Place Instead of Wrapping + +Add the five provenance fields directly to `SemanticEvent`. Rejected: `SemanticEvent` is already serialized to MQTT/Matter and is the subject of five proptest invariants in `bus.rs`. Mutating it churns the wire format and the tests simultaneously. The wrapper + `as_event()` shim isolates the change, keeps the proptest suite green, and lets callers migrate incrementally. + +### 4.2 Put Provenance in the `Reason` Tags + +`Reason` is already a `Vec` (`common.rs:50-65`); one could append `"model=ha-mind-v2.1"` tags. Rejected: tags are human-readable debug strings, not a machine schema. An automation would have to string-parse tags to find the model version, which is brittle and untyped. Provenance must be typed fields so consumers and the recorder can query them structurally. + +### 4.3 Alias `Rest` to `NoMovement` + +Reuse `NoMovement` for the rest state with a different threshold. Rejected in §2.5: `NoMovement` is a *safety/escalation* primitive (possible collapse), `Rest` is a *suppression* primitive (don't disturb). They carry opposite automation intent and different dwell/motion semantics; conflating them would make it impossible for an automation to distinguish "resting" from "possibly collapsed" — the exact distinction caregivers need. + +### 4.4 Route All Records to the Agent + +Send every `SemanticStateRecord` to the Ruflo agent and let the LLM decide everything. Rejected: most records (a single `room_active` toggle) need no LLM reasoning, and the agent subprocess (ADR-133) has a 5 s timeout (`runner.rs:51`) and per-call cost. The declarative `AgreementRule` set filters to the multi-signal cases that actually need cross-primitive reasoning, keeping the single-signal path deterministic and free. + +### 4.5 Enforce Privacy at the Record Layer + +Have `SemanticStateRecord` redact itself (drop `room`, strip biometrics) before publishing. Rejected: redaction must happen at the wire boundary so the same record can be published differently to different transports (full to a local trusted HOMECORE state machine, anonymized to an external MQTT broker). The record carries the *action*; `mqtt/privacy.rs` applies the *transform* per transport. This also keeps the enforcement point co-located with the existing biometric filter, so ADR-141's attestation can verify one place. + +--- + +## 5.

Context + +### 1.1 The Gap + +The BFLD crate (`v2/crates/wifi-densepose-bfld/src/`) already implements a complete, structurally enforced privacy posture, but it does so entirely in terms of a **4-value numeric class** — there is no first-class concept of a deployment *mode* and no concept of a discrete privacy *action*. Reading the real code: + +- `lib.rs` defines `PrivacyClass` as `#[repr(u8)]` with four variants `Raw = 0`, `Derived = 1`, `Anonymous = 2`, `Restricted = 3`, plus `allows_network()` / `allows_matter()` / `as_u8()` (`lib.rs:82-117`). This is the entire vocabulary the system has for "what is this deployment allowed to emit." Nothing names *why* a node is at class 2 vs class 3, nor records which privacy transformations were actually applied. +- `privacy_gate.rs` implements `PrivacyGate::demote()` — a monotonic, zeroizing transformer that strips payload sections (`compressed_angle_matrix`, `csi_delta`, `amplitude_proxy`, `phase_proxy`) on each class transition (`privacy_gate.rs:31-75`). The stripping is real and irreversible, but it is **silent**: nothing records *which* sections were zeroed for *which* frame. There is no audit trail and no way for a downstream verifier to prove what was stripped. +- `sink.rs` enforces I1 at compile time via `Sink::MIN_CLASS` and the runtime `check_class::()` (`sink.rs:47-55`), with the three concrete `LocalKind`/`NetworkKind`/`MatterKind` tags. The MQTT topic router (`mqtt_topics.rs:109-157`) and HA discovery (`ha_discovery.rs:61-129`) hard-code the rule "publish only at class >= Anonymous, and `identity_risk` only at exactly Anonymous." This is an *implicit ACL* scattered across two files; it is not declared in one place and is not bound to a named mode. +- `identity_risk.rs` defines `GateAction { Accept, PredictOnly, Reject, Recalibrate }` (`identity_risk.rs:57-69`) — but these are *risk-gating* actions on a per-event basis, not *privacy* actions. There is no enum that names the privacy transformation a mode enforces (e.g., "suppress identity", "drop raw", "aggregate only"). +- `emitter.rs` hard-codes `privacy_class: PrivacyClass::Anonymous` as the constructed default (`emitter.rs:82`) and the Soul Signature gate is controlled only by whether a `SoulMatchOracle` is supplied (`emitter.rs:138`, `coherence_gate.rs:71`). Whether Soul Signature is *enabled* for a deployment is not a declared policy — it is an implicit consequence of construction-site wiring. + +The consequence: a deployment's privacy stance is encoded in **four separate places** — the constructed `PrivacyClass`, the presence/absence of a `SoulMatchOracle`, the class-gated MQTT/HA fan-out, and the `signature_hasher` install — with no single declared object that says "this node runs in *CareWithConsent* mode, which means class Derived, Soul Signature enabled, identity_risk published, raw never networked." There is no runtime artifact a regulator, a Home Assistant dashboard, or the WorldGraph (ADR-139) can read to learn the *effective* policy, and no cryptographic proof that the policy was actually enforced frame-by-frame. + +ADR-140 (Semantic State Record) requires that every semantic state trace to a `privacy_action`. ADR-139 (WorldGraph) needs a `privacy_limited_by` annotation to compute which edges/zones are degraded by privacy. Neither has anything to bind to today: BFLD exposes a numeric class but no *action* and no *attestation*. This ADR closes that gap. + +### 1.2 What "Mode", "Action", and "Attestation" Mean Here + +- A **PrivacyMode** is a named, operator-facing deployment posture (e.g., `CareWithConsent`). It is the human-meaningful unit a regulator or installer reasons about. It is *not* a new enforcement primitive — it is a declarative selection that *maps to* the existing `PrivacyClass`, plus a Soul Signature gate decision, plus an MQTT/Matter ACL. +- A **PrivacyAction** is the discrete, machine-checkable privacy transformation that a mode enforces (e.g., `SuppressIdentity`, `DropRaw`). Actions are the bridge between the human mode and the byte-level stripping `privacy_gate.rs` already performs. They are what ADR-140's `privacy_action` field carries. +- A **PrivacyAttestationProof** is a hash-chained record (per ADR-010) of *which mode was active, which actions were enforced, and which fields were stripped per event*. It is the cryptographic continuity proof that the declared mode was honored, surfaced read-only to HA/Matter diagnostics. + +What this ADR is **not**: it does not change the four `PrivacyClass` byte values, does not weaken any structural invariant (I1/I2/I3 from `lib.rs:8-11`), and does not replace `PrivacyGate::demote()` — it *records* what `demote()` did. + +### 1.3 Pipeline Position + +``` +SensingInputs + → BfldEmitter::emit() (identity_risk + CoherenceGate) + ↑ consults + PrivacyModeRegistry::active_mode() ← NEW + ↓ resolves to (PrivacyClass, Soul gate, ACL) + → PrivacyGate::demote(frame, target_class) (existing; now records stripped fields) + ↓ emits per-frame + PrivacyActionRecord { actions, fields_stripped } ← NEW + ↓ folded into + PrivacyAttestationProof { mode, actions, fields_stripped_per_event, prev_hash } ← NEW (hash-chained, ADR-010) + ↓ surfaced + mqtt_topics.rs / ha_discovery.rs (active mode + proof hash diagnostic entity) + ↓ consumed by + ADR-139 privacy_limited_by / ADR-140 privacy_action +``` + +The registry is consulted once per class transition (not once per byte).

The actions are intentionally orthogonal to `GateAction` (`identity_risk.rs:57`): `GateAction` answers "is this *event* too risky to publish?"; `PrivacyAction` answers "what privacy transformation does the active *mode* require on every event?" They compose — a mode may enforce `SuppressIdentity` while the per-event gate independently `Reject`s. + +### 2.3 `PrivacyModeRegistry`: Single Source of Truth + Append-Only Audit Log + +The registry is the one declared object that the gap (§1.1) is missing.

Enterprise enables `multiseed_salt()` so that two seeds observing the same person in adjacent units produce uncorrelated `rf_signature_hash` values, preserving I3 (`signature_hasher.rs:8-18`) across a shared tenant boundary. Single-home does not need this. Both publish `identity_risk` at class 2 per the existing `ha_discovery.rs:116` rule — Enterprise additionally enforces `AggregateOnly` semantically, suppressing any zone-level or per-cluster surface beyond the five aggregate entities. +- **`CareWithConsent` → `Derived` with Soul on.** This is the only mode that resolves to class `Derived`, matching `lib.rs:88-90`'s comment "Required for Soul Signature deployments." It enables `soul-signature` (the Cargo feature, `Cargo.toml:24-27`) and installs a real `SoulMatchOracle` so the gate's `Recalibrate` exemption (`coherence_gate.rs:71-84`) fires for enrolled subjects. Class `Derived` is *not* on the public MQTT tree (`mqtt_topics.rs:111` requires `>= Anonymous`), so consented identity data stays on LAN/research surfaces — `DropRaw` and `ReduceResolution` still apply. + +### 2.5 `PrivacyAttestationProof`: Hash-Chained Per ADR-010 + +The attestation proof gives cryptographic continuity that the declared mode was honored. It reuses the ADR-010 witness-chain primitive directly: each proof entry includes the SHAKE-256/BLAKE3 hash of the previous entry (`ADR-010` §"Hash chain", `previous_hash`/`entry_hash` linkage), so any insertion, deletion, or reordering breaks verification. + +```rust +// v2/crates/wifi-densepose-bfld/src/attestation.rs +#![cfg(feature = "std")] + +use crate::mode::{PrivacyAction, PrivacyMode}; +use blake3::Hasher; // already a dependency (Cargo.toml:33) + +/// Per-event privacy enforcement record — the unit folded into the chain. +#[derive(Debug, Clone, PartialEq, Eq)] +pub struct PrivacyActionRecord { + /// Capture-clock ns of the event this record attests. + pub timestamp_ns: u64, + /// Strongest action enforced for this event (ADR-140 `privacy_action`). + pub strongest_action: PrivacyAction, + /// Names of payload/event fields stripped for this event, e.g. + /// "compressed_angle_matrix", "rf_signature_hash".

A per-frame chain at 20 Hz would grow at 1,728,000 links/day; per-window keeps the chain bounded to the published-event rate while still attesting every strip (each window's `fields_stripped_per_event` enumerates the per-event strips inside it). BLAKE3 is reused (it is already a dependency, `Cargo.toml:33`) rather than introducing the SHAKE-256 used in ADR-010's MAT path — ADR-010 §"Hash chain" specifies a hash-linked chain but not a fixed algorithm; BFLD already keys its `rf_signature_hash` with BLAKE3 (`signature_hasher.rs:20`), so reusing it avoids a second crypto dependency in the no-`std`-capable crate. + +### 2.6 Integration Into MQTT Discovery + a Read-Only HA Diagnostic Entity + +The active mode and proof hash are surfaced as a **read-only diagnostic** so an operator, regulator, or the cognitum-v0 dashboard can see the live privacy posture without touching the sensing entities. This extends `ha_discovery.rs` and `mqtt_topics.rs`, both of which already class-gate every entity. + +- A new discovery payload is rendered by `render_discovery_payloads()` (`ha_discovery.rs:61`) for a `sensor` with `entity_category = "diagnostic"`, unique-id `_bfld_privacy_mode`, state topic `ruview//bfld/privacy_mode/state`. Its state is a compact JSON object `{"mode":"care_with_consent","class":"derived","proof":"blake3:<16hex>","actions":["drop_raw","reduce_resolution"]}`. +- The entity is published at every class `>= Anonymous` (same gate as the existing five diagnostic sensors) **and** additionally at class `Raw`/`Derived` on the LAN-only research surface — because a research/care deployment most needs to display its own attestation. The class gate for the *public* tree (`mqtt_topics.rs:111`) is unchanged; the diagnostic mode entity is added to the local diagnostic surface regardless of class so the proof is always inspectable on-node. +- It is strictly read-only: the entity has no `command_topic`. Mode changes are an operator/config action (TOML + restart, §2.7), never an MQTT write — consistent with the "no `promote`" posture of `privacy_gate.rs`. + +The proof hash on this entity is the `short_hash()` of the most recently sealed `PrivacyAttestationProof`. A verifier with the full chain (exported via a future `attestation export` CLI) can confirm continuity from genesis to the displayed hash. + +### 2.7 Registry Wiring Into the Emitter + +`BfldEmitter` (`emitter.rs:65-88`) gains an owned `PrivacyModeRegistry` and seals one attestation link per emit window. The change is additive — the existing `emit()`/`emit_with_oracle()` signatures are unchanged; the registry is configured via a new builder. + +```rust +// emitter.rs additions (sketch) +pub struct BfldEmitter { + // ...existing fields (node_id, default_zone_id, privacy_class, gate, ring, signature_hasher) + registry: PrivacyModeRegistry, // NEW — single source of truth + last_proof_hash: [u8; 32], // NEW — chain tail; [0;32] genesis +} + +impl BfldEmitter { + /// Configure the emitter from a named mode.

The configured baseline mode (default `PrivateHome`) preserves the current `Anonymous` default (`emitter.rs:82`), so an un-migrated caller sees identical behavior plus a populated attestation chain. + +### 2.8 Downstream Consumers (ADR-139, ADR-140) + +| Consumer | What it reads | Binding | +|----------|---------------|---------| +| ADR-140 Semantic State Record | `PrivacyActionRecord::strongest_action` | Populates the record's mandatory `privacy_action` field; the proof `entry_hash` populates the record's privacy-provenance reference | +| ADR-139 WorldGraph | `PrivacyModeRegistry::is_action_enforced(AggregateOnly)` / `ReduceResolution` | A zone/edge whose evidence was degraded by `ReduceResolution` or `AggregateOnly` is tagged `privacy_limited_by = ` so the digital twin can mark the region as privacy-degraded rather than sensor-blind | +| ADR-136 Streaming Engine | `attestation()` short hash | Stage-boundary frame contract may carry the active mode token for downstream stages without re-deriving it | +| `ha_discovery.rs` / `mqtt_topics.rs` | active mode + `short_hash()` | Read-only diagnostic entity (§2.6) | + +This honors the project rule that every semantic state traces to **signal evidence + model version + calibration version + privacy decision**: ADR-141 supplies the *privacy decision* half — the `PrivacyActionRecord` (what was enforced) plus the chain `entry_hash` (proof it was enforced) — which ADR-140 records alongside the signal/model/calibration provenance from ADR-134/ADR-135. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Single declared policy object.** A deployment's privacy stance is now one named `PrivacyMode` and a `PrivacyModeRegistry`, not four scattered wiring decisions. An installer selects `CareWithConsent`; the registry derives class, Soul gate, salt domain, and ACL deterministically. +- **Cryptographic continuity.** `PrivacyAttestationProof` makes "we ran in StrictNoIdentity and stripped identity on every event" a verifiable claim, not a code-review assertion. The chain reuses the ADR-010 primitive, so the existing witness verifier extends naturally. +- **Regulator/operator visibility.** The read-only HA diagnostic entity exposes the live mode and proof hash without widening the sensing surface — useful for care-home compliance audits. +- **Clean ADR-139/ADR-140 bindings.** `privacy_action` and `privacy_limited_by` now have a concrete, queryable source (`is_action_enforced`, `strongest_action`), closing the trace requirement for semantic state. +- **No wire/byte changes.** `PrivacyClass` byte values, `BfldFrameHeader`, `sink.rs` ACL, and the MQTT topic tree are untouched. Modes are purely additive. + +### 3.2 Negative + +- **Two same-class modes.** `PrivateHome` and `EnterpriseAnonymous` both resolve to `Anonymous`; the difference (salt domain, `AggregateOnly`) lives above the class layer and is only meaningful if downstream consumers honor the action set. A consumer that looks only at `PrivacyClass` will not distinguish them. +- **Chain growth.** Even per-window, a busy node accumulates attestation links. An export/prune policy (genesis re-anchoring after verified export) is needed and is deferred to a follow-up iter. +- **`emitter.rs` gains state.** The emitter now owns a registry and a chain tail, growing its memory footprint and making `emit()` no longer a pure transform of inputs→event. The seal cost (one BLAKE3 over a small buffer) is sub-microsecond but non-zero. +- **Mode change requires restart.** By design there is no MQTT command topic to change mode at runtime (mirrors `privacy_gate.rs`'s no-`promote` posture). Operators change mode via TOML config + restart, which is a heavier operation than a dashboard toggle. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Mode→action mapping drifts from what `privacy_gate.rs` actually strips, so the proof attests fields that were not really removed | Medium | Attestation lies — worse than no attestation | The `PrivacyActionRecord.fields_stripped` is populated from the *actual* gate output (`event.rs`/`privacy_gate.rs` return values), not from the mode table; a unit test asserts the recorded strips equal the bytes the gate zeroed | +| `EnterpriseAnonymous` multiseed salt not actually isolated (two seeds share a salt) → I3 broken under same class | Low | Cross-unit identity correlation | `multiseed_salt()` gates a per-seed `site_salt` derivation; an acceptance test asserts cross-seed Hamming distance ~128 bits (reusing ADR-120 §2.7 AC2 from `tests/signature_hasher.rs`) | +| Chain genesis confusion: a node that restarts mid-deployment starts a fresh genesis, breaking continuity from the prior chain | Medium | Verifier sees a discontinuity it cannot distinguish from tampering | Genesis links record `prev_hash = [0;32]` and a boot epoch; the verifier treats a genesis link with a logged restart event as a legitimate re-anchor, not a break | +| Operator selects `RawResearch` and assumes raw never networks, but a misconfigured custom `Sink` accepts class 0 | Low | I1 violation | `RawResearch`'s `DropRaw` action is redundant with the compile-time `sink.rs` ACL (`MIN_CLASS`); the registry's `allows_sink::()` returns `false` for `Raw`, giving a runtime second line of defense | + +--- + +## 4. Alternatives Considered + +### 4.1 Extend `PrivacyClass` to Five+ Variants Instead of Adding `PrivacyMode` + +Collapsing modes into the class enum would avoid a second type. Rejected because `PrivacyClass` is a *wire and sink-enforcement* primitive: its byte values are serialized in `BfldFrameHeader`, switched on in `sink.rs::check_class`, the MQTT router, and the NVS/Matter representation. Two modes (`PrivateHome`, `EnterpriseAnonymous`) share the same class but differ only in salt domain — they are *not* separable at the byte layer, so they cannot be class variants without inventing byte semantics that the existing `frame.rs`/`sink.rs` code would have to learn. Modes are strictly higher-level and must not perturb the byte contract. + +### 4.2 Per-Frame Attestation Chain + +A chain link per CSI frame would attest every single frame. Rejected on growth grounds: 20 Hz × 86,400 s = 1.7 M links/day/node, unbounded. The per-window granularity (§2.5) attests every *strip* (each window enumerates its per-event records) at the published-event rate, which is orders of magnitude lower while losing no strip evidence. + +### 4.3 Reuse `GateAction` Instead of a New `PrivacyAction` Enum + +`GateAction { Accept, PredictOnly, Reject, Recalibrate }` already exists (`identity_risk.rs:57`). Rejected because it answers a different question — *per-event risk gating* — and overloading it would conflate "this event is risky" with "this mode strips identity on every event." They compose (a mode can `SuppressIdentity` while the gate independently `Reject`s); merging them would lose that orthogonality and break ADR-140's need for a stable `privacy_action` value independent of per-event risk. + +### 4.4 Runtime Mode Changes via MQTT Command Topic + +A `command_topic` would let a dashboard flip modes live. Rejected for the same reason `privacy_gate.rs` has no `promote`: a remote, unauthenticated-by-default MQTT write that *weakens* privacy (e.g., `StrictNoIdentity` → `RawResearch`) is a privilege-escalation surface. Mode is a config-time + restart decision; the diagnostic entity is read-only. + +### 4.5 SHAKE-256 (Match ADR-010 Exactly) vs BLAKE3 Reuse + +ADR-010's MAT path uses SHAKE-256. Adopting it here would mean a second crypto dependency in a crate that is `#![cfg_attr(not(feature = "std"), no_std)]` (`lib.rs:14`). Rejected: ADR-010 §"Hash chain" specifies a hash-*linked* chain, not a fixed algorithm, and BFLD already depends on BLAKE3 for `rf_signature_hash` (`signature_hasher.rs:20`, `Cargo.toml:33`). Reusing BLAKE3 keeps the no-std footprint minimal while satisfying the linkage/tamper-evidence contract. + +--- + +## 5. Testing and Acceptance Criteria + +### 5.1 Test Plan + +**T1 — Mode→class/Soul/salt mapping (unit).** For each of the five `PrivacyMode` variants, assert `privacy_class()`, `soul_signature_enabled()`, and `multiseed_salt()` exactly match the §2.4 table. Assert `token()` round-trips through a `from_token()` parser. + +**T2 — Canonical action set (unit).** For each mode, assert `actions_for(mode)` equals the §2.4 "Enforced actions" column, is sorted ascending (`Ord`), and is deduplicated. Assert `is_action_enforced` agrees with set membership for all 25 (mode, action) pairs. + +**T3 — ACL agreement with `sink.rs` (unit).** For each mode, assert `registry.allows_sink::()`, `::()`, `::()` equal `check_class::(mode.privacy_class()).is_ok()` — i.e., the registry ACL never disagrees with the compile-time sink ACL. In particular `RawResearch.allows_sink::() == false` (I1). + +**T4 — Attestation chain linkage (unit).** Seal a genesis link (`prev_hash = [0;32]`), then three more, threading each `entry_hash` into the next `prev_hash`. Assert `verify_link()` passes for all four against the correct predecessors. Mutate one link's `mode` and assert `verify_link()` fails (tamper evidence). Insert/delete/reorder a link and assert verification breaks. + +**T5 — Recorded strips equal actual gate output (unit).** Run `BfldEmitter::with_mode(StrictNoIdentity)`, emit an event that would carry `identity_risk_score` + `rf_signature_hash`, and assert: (a) the emitted `BfldEvent` has both fields `None` (existing `event.rs:113` behavior), AND (b) the sealed `PrivacyActionRecord.fields_stripped` equals `["identity_risk_score","rf_signature_hash"]` (sorted) — proving the proof attests what was really stripped, not what the table claims. + +**T6 — Multiseed salt isolation (unit, reuses ADR-120 AC2).** Two emitters in `EnterpriseAnonymous` with distinct per-seed salts observing identical identity features produce `rf_signature_hash` values with Hamming distance in [112, 144] bits (≈128 expected).

Context + +### 1.1 The Gap + +The RuvSense crate already contains every individual ingredient an "evolution tracker" would need, but they exist as five disconnected modules with no orchestrator that runs them together over time and across links. Searching `v2/crates/wifi-densepose-signal/src/ruvsense/` for `EvolutionTracker`, `change_point`, `VoxelMap`, and any cross-module driver finds nothing. What does exist: + +- **`field_model.rs`** holds the per-link Welford baselines (`LinkBaselineStats`, `WelfordStats` at line 79), runs the SVD eigenstructure decomposition (`finalize_calibration()`, line 487), exposes `estimate_occupancy(&[Vec]) -> Result` (line 741, with a `NotCalibrated` stub at line 821 when the `eigenvalue` feature is off), and tracks calibration freshness via `check_freshness(current_us) -> CalibrationStatus` (line 829) returning `Uncalibrated | Collecting | Fresh | Stale | Expired` (enum at line 300). Nothing aggregates freshness *across* links — each `FieldModel` instance is per-room and unaware of its siblings. +- **`calibration.rs`** (ADR-135) holds the empty-room amplitude/phase baseline: `BaselineCalibration` (line 228), `CalibrationRecorder` with a `W`-frame staleness window, `deviation(&CsiFrame) -> CalibrationDeviationScore` (line 238), and `CalibrationError` (line 128). Its `CalibrationDeviationScore` (line 372) carries the per-frame `drift_score`, but the drift signal is consumed only by that single link's recorder. There is no cross-link rule that says "3 links drifted simultaneously, therefore the room changed." +- **`longitudinal.rs`** holds the per-person `PersonalBaseline` (line 156) with five Welford metrics and an `EmbeddingHistory` FIFO (line 344, `push()` at line 389, `novelty()` at line 500). It produces a `DriftReport` (line 110) and a `MonitoringLevel` (line 99) per person — but per-person, never tied back to the per-link RF evidence that produced the embedding. +- **`attractor_drift.rs`** holds phase-space regime classification: `AttractorDriftAnalyzer` (line 203), `analyze()` (line 257) returning `AttractorDriftReport { regime_changed, ... }` (line 136), classifying `BiophysicalAttractor` (line 93). Again per-person-per-metric; nothing escalates a regime change into the field/calibration tier. +- **`tomography.rs`** holds the coarse RF tomographer: `RfTomographer` (line 178), `reconstruct(&[f64]) -> OccupancyVolume` (line 236) with an ISTA L1 solver, and an `OccupancyVolume` (line 121) of `densities: Vec`. Critically, **the `OccupancyVolume` is stateless** — every `reconstruct()` call produces a fresh volume from a single attenuation snapshot. There is no temporal memory: a voxel that has been occupied for 200 frames is indistinguishable from one that flickered for a single noisy frame. There is no per-voxel confidence, no `last_update_ns`, no evidence count, and no Doppler. + +On the privacy side, `wifi-densepose-bfld/src/privacy_gate.rs` implements the monotonic `PrivacyGate::demote(BfldFrame, PrivacyClass)` (line 31) that zeroes payload sections going `Raw(0) → Derived(1) → Anonymous(2) → Restricted(3)` (classes defined in `bfld/src/lib.rs` line 84), refusing any promotion with `BfldError::InvalidDemote` (line 187). But the gate operates on `BfldFrame` payload sections (`compressed_angle_matrix`, `csi_delta`, `amplitude_proxy`, `phase_proxy`) — **it has no concept of a voxel grid**. A tomographic `OccupancyVolume`, if it were ever emitted, would leave the node ungated. + +The gap is therefore twofold: + +1. **No orchestrator.** Each link maintains its own baseline, drift score, attractor state, and occupancy estimate in isolation. A change in the physical environment (furniture moved, a wall opened) manifests as correlated drift across *several* links, but no module reads more than one link at a time. Cross-link change-point detection — the signal that distinguishes "the world changed" from "this one link is noisy" — does not exist. +2. **No temporal occupancy memory.** `RfTomographer::reconstruct()` is memoryless, so occupancy cannot accumulate evidence, cannot be assigned confidence, and cannot be Bayesian-updated across the 20 Hz reconstruction cadence. And whatever it produces is not gated for privacy. + +ADR-030 (Persistent Field Model, Proposed) defines the per-room field model and Tier-2 tomography but says nothing about orchestrating multiple rooms/links or about temporal voxel state. This ADR extends ADR-030 with the missing orchestration layer and the missing temporal voxel layer, and routes both through the BFLD privacy gate (ADR-120/ADR-141). + +### 1.2 What "Evolution" Means Here + +"Evolution" is the second-order signal: not the instantaneous state of the field, but **how the field's statistical description is changing over time and whether that change is coherent across links**. Three concrete questions the EvolutionTracker answers that no current module can: + +- *Are the per-link baselines still valid as a set?* (freshness across the mesh, not per-link) +- *Did the environment just change, or is one link misbehaving?* (cross-link change-point) +- *Does the model's occupancy estimate agree with the raw RF body-perturbation energy?* (occupancy-consistency, an internal contradiction check feeding ADR-137) + +### 1.3 What This ADR Is Not + +It is not a new tomography solver — it wraps the existing `RfTomographer`. It is not a new calibration algorithm — it reads ADR-135's `BaselineCalibration` and ADR-030's `FieldModel`. It is not a new privacy model — it reuses the `PrivacyGate::demote` pattern from `bfld/src/privacy_gate.rs`. It adds exactly two things: a coordinator (`EvolutionTracker`) and a stateful, gated occupancy memory (`VoxelMap` + `VoxelGate`). + +### 1.4 Pipeline Position + +``` +Per-link CSI frame (baseline-subtracted, ADR-135) + → CalibrationRecorder::record() (ruvsense/calibration.rs) → drift_score[link] + → FieldModel::extract_perturbation() (ruvsense/field_model.rs) → body_energy[link] + → RfTomographer::reconstruct() (ruvsense/tomography.rs) → OccupancyVolume (snapshot) + │ │ │ + └────────────────┴───────────────────────┴──► EvolutionTracker::tick() ← NEW + ├─ baseline freshness across mesh + ├─ cross-link change-point + ├─ occupancy-consistency check + └─ VoxelMap::ingest(volume) ← NEW (temporal) + │ + VoxelGate::demote(map, mode) ← NEW (BFLD-gated) + │ + ┌─────────────────────────────────────┴───────────────────┐ + ADR-137 contradiction flags ADR-139 WorldGraph nodes +``` + +`EvolutionTracker::tick()` runs once per reconstruction cycle (20 Hz).

The rule, evaluated every tick: + +> Within the rolling `change_point_window` (default 30 frames / 1.5 s), if **3 or more links** each exceed `change_point_sigma` (default 2.0σ) on their `rms_amplitude_z`, emit a `ChangePoint` event naming those links. + +```rust +fn detect_change_point(&self) -> Option> { + let mut hot = Vec::new(); + for (link_id, window) in self.z_windows.iter() { + // Count frames in the window above the sigma threshold. + let n_hot = window.iter().filter(|&&z| z >= self.config.change_point_sigma).count(); + // A link "participates" if it was hot for a majority of the window. + if n_hot * 2 > window.len() { + hot.push(*link_id); + } + } + (hot.len() >= self.config.change_point_min_links).then_some(hot) +} +``` + +The 3-link minimum is deliberately the same scale as ADR-135's `drift_confirm_frames` confirmation logic but operates spatially instead of temporally: ADR-135 confirms a single link's staleness over 45 s; this ADR confirms an environment change over 3 links in 1.5 s. The two are complementary — ADR-135 answers *"is this link's baseline old?"* and this rule answers *"did the world just move?"*. A `ChangePoint` is the upstream trigger that lets the operator (or, if `recalibrate_on_drift` from ADR-135 §2.6 is enabled) recalibrate the *whole mesh* rather than one link. + +The 2.0σ threshold reuses ADR-135's interpretation: `rms_amplitude_z > 3.0` is "likely occupied" for a single frame, so a *sustained* 2.0σ across a 1.5 s window on multiple links is a structural shift, not a single body passing one link. + +**Mesh freshness aggregation.** Independently of change-points, the tracker reduces per-link `CalibrationStatus` to one `mesh_freshness` using the worst-case ordering `Fresh < Stale < Expired` (with `Uncalibrated`/`Collecting` treated as worse than `Fresh`). Any link at `Stale` or `Expired` lands in `stale_links` and produces a `CoherenceAlert`. This is the cross-mesh freshness check that `field_model.rs::check_freshness` cannot do alone — it only knows one room. + +### 2.3 Occupancy-Consistency Check + +Two independent occupancy estimates exist and should agree: + +- **Model occupancy**: `FieldModel::estimate_occupancy(recent_frames)` (field_model.rs line 741) — derived from eigenstructure energy in the off-environment subspace. +- **Perturbation occupancy**: a count derived from the summed per-link `body_energy` (the residual after `extract_perturbation()` projects out the environmental modes). The tracker bins total body energy into a person count using a fixed energy-per-person scale calibrated at install. + +```rust +fn occupancy_consistency(&self, model_occ: usize, body_energy_total: f32) -> (usize, bool) { + let perturbation_occ = (body_energy_total / self.energy_per_person).round() as usize; + let disagree = model_occ.abs_diff(perturbation_occ) > self.config.occupancy_tolerance; + (perturbation_occ, disagree) +} +``` + +When the two disagree by more than `occupancy_tolerance` (default 1 person), the tracker emits `AnomalyWarn { model, perturbation }`. This is exactly the kind of *internal contradiction* ADR-137's fusion quality scoring consumes: the semantic state record produced downstream carries this as a contradiction flag with references to both evidence sources (the field model version and the calibration version that produced each estimate). Per the project rule, every semantic state traces to **signal evidence** (the `LinkObservation` set), **model version** (the `FieldModel` SVD generation), **calibration version** (the `BaselineCalibration.captured_at_unix_s` from ADR-135), and **privacy decision** (the `VoxelGate` mode, §2.5). + +### 2.4 Temporal `VoxelMap` with Bayesian Evidence Accumulation + +The core new state. The existing `OccupancyVolume` (tomography.rs line 121) is a memoryless snapshot. The `VoxelMap` is the persistent companion that accumulates evidence across `reconstruct()` calls. + +```rust +/// One voxel of persistent, evidence-accumulating occupancy state. +#[derive(Debug, Clone)] +pub struct Voxel { + /// Center position (metres), copied from OccupancyVolume::voxel_center(). + pub center_xyz: [f32; 3], + /// Bayesian occupancy probability ∈ [0, 1]. + pub occupancy: f32, + /// Confidence ∈ [0, 1]; rises with evidence_count, falls with staleness. + pub confidence: f32, + /// Nanoseconds (802.15.4 epoch) of the last frame that updated this voxel. + pub last_update_ns: u64, + /// Number of frames that have contributed evidence to this voxel. + pub evidence_count: u32, + /// Welford mean/variance of the density observations (variance flags noise). + pub density_mean: f32, + pub density_m2: f32, + /// Radial Doppler velocity estimate (m/s), when CIR phase rate is available. + pub doppler_velocity: f32, +} + +/// Persistent occupancy grid shared across all reconstruct() calls. +#[derive(Debug, Clone)] +pub struct VoxelMap { + pub voxels: Vec, + pub nx: usize, + pub ny: usize, + pub nz: usize, + pub bounds: [f64; 6], + /// Half-life (frames) of the confidence decay for un-updated voxels. + decay_half_life: f32, +} + +impl VoxelMap { + /// Allocate a VoxelMap matching an OccupancyVolume's geometry. + pub fn from_geometry(volume: &OccupancyVolume) -> Self; + + /// Fold one fresh OccupancyVolume into the persistent map. + /// + /// For each voxel: + /// 1.

Log-odds accumulation is the standard occupancy-grid update (Moravec & Elfes, 1985; Thrun et al., 2005): it is commutative and numerically stable, and it lets a voxel that is repeatedly observed occupied converge toward 1.0 while a one-frame flicker barely moves the estimate. This directly solves the memoryless-snapshot problem: a 200-frame occupancy is now distinguishable from a 1-frame spike via `evidence_count` and the converged log-odds. + +**Confidence and low-confidence flagging.** `confidence = logistic(evidence_count / min_evidence) × (1 − clamp(normalised_density_variance))`. Voxels with `evidence_count < min_evidence_frames` (default 5, §2.1) are returned by `low_confidence_indices()` and flagged downstream so the fusion engine (ADR-137) never treats a 4-frame voxel as a confident detection. This mirrors how `tomography.rs` already counts `occupied_count` at density > 0.01, but adds the *temporal* qualifier the snapshot lacks. + +**Welford variance per voxel.** Reuses the exact `(mean, m2)` update form of `WelfordStats` from `field_model.rs` (line 79–162) so a voxel whose density is high but *noisy* (high variance) is correctly distrusted relative to a voxel that is steadily, quietly occupied. + +### 2.5 CIR-Weighted Tomography (ADR-134 Integration) + +When ADR-134 CIR is available, the `dominant_delay_sec()` / `dominant_tap_tof_s()` of a link's `Cir` (cir.rs lines 291–309) gives a time-of-flight, hence a distance, for the dominant reflector on that link. The `RfTomographer` weight matrix (tomography.rs line 182, `weight_matrix: Vec>`) currently weights every voxel on the link path purely by Fresnel-radius proximity (`1.0 − dist/fresnel_radius`). With a CIR delay available, the tracker supplies a *distance prior*: voxels whose distance from TX matches the CIR-implied range get their weight boosted, focusing evidence near the reflector instead of smearing it along the whole ray. + +```rust +/// Optional per-link CIR-derived distance prior, applied to the existing +/// Fresnel weights as a multiplicative Gaussian bump centred at the CIR range. +pub struct CirDistancePrior { + pub link_id: LinkId, + /// Reflector distance from TX (m), from Cir::dominant_distance_m(). + pub range_m: f64, + /// Std-dev of the range bump (m), from tap_spacing → distance resolution. + pub sigma_m: f64, +} +``` + +The prior is **optional**: when CIR is unavailable (single-antenna fallback, or the `eigenvalue`/CIR feature is off), the tomographer behaves exactly as today. This keeps the change additive and the existing `tomography.rs` tests untouched. The Doppler field of each `Voxel` (`doppler_velocity`) is similarly populated only when CIR phase-rate is available; otherwise it stays 0.0. + +### 2.6 `VoxelGate`: BFLD-Gated Voxel Output + +The raw `VoxelMap` is identity-leaky: a high-resolution occupancy grid plus per-voxel Doppler can reconstruct a person's trajectory and gait. It must never leave the node un-gated. `VoxelGate::demote` reuses the **monotonic-demotion** pattern of `bfld/src/privacy_gate.rs::PrivacyGate::demote` — it accepts a `PrivacyClass` (from `bfld/src/lib.rs`, classes `Raw(0) → Derived(1) → Anonymous(2) → Restricted(3)`), refuses any *promotion* with `BfldError::InvalidDemote`, and produces progressively coarser views. Like the BFLD gate, demotion is irreversible: once a field is zeroed, the bytes are gone. + +```rust +use wifi_densepose_bfld::{BfldError, PrivacyClass}; + +/// Monotonic voxel-grid demotion, mirroring PrivacyGate::demote (ADR-120). +pub struct VoxelGate; + +/// What actually leaves the node after gating. +#[derive(Debug, Clone)] +pub enum GatedVoxelOutput { + /// Raw(0)/Derived(1): full VoxelMap (local-only by invariant; Raw never + /// crosses a network sink — same structural rule as BFLD class 0). + Full(VoxelMap), + /// Anonymous(2): per-voxel doppler_velocity and confidence cleared to 0; + /// occupancy retained but quantised.

The control-plane *which* class applies comes from ADR-141 (the named privacy mode and its runtime attestation), not from this ADR — `VoxelGate` is the mechanism, ADR-141 is the policy. + +**Anomaly routing.** `EvolutionReport.alerts` (the `CoherenceAlert` / `ChangePoint` / `AnomalyWarn` variants) are not voxel data and are not subject to voxel demotion — they are *typed events*. They route to: + +- **ADR-137** fusion contradiction flags: `AnomalyWarn` becomes a contradiction reference (model-occupancy vs perturbation-occupancy) attached to the semantic state record, with the model version and calibration version that produced each side. +- **ADR-139** WorldGraph nodes: a `ChangePoint` updates the environmental digital twin (e.g. a moved-furniture edge), and `CoherenceAlert` marks affected room nodes as needing recalibration. + +### 2.7 Interface Boundaries + +| Boundary | Direction | Type | Note | +|----------|-----------|------|------| +| `calibration.rs` → tracker | in | `CalibrationDeviationScore` (per link) | drift_score + rms_amplitude_z; no CSI crosses the boundary | +| `field_model.rs` → tracker | in | `CalibrationStatus`, `body_energy: f32`, `estimate_occupancy` | mesh freshness + model occupancy | +| `tomography.rs` → tracker | in | `&OccupancyVolume` (snapshot) | folded into `VoxelMap::ingest` | +| `cir.rs` → tracker | in (optional) | `CirDistancePrior` | distance-weighted evidence; absent ⇒ unchanged behaviour | +| tracker → ADR-137 | out | `EvolutionAlert` (typed) | contradiction flags, evidence references | +| tracker → ADR-139 | out | `EvolutionAlert` (typed) | WorldGraph mutations | +| tracker → network sink | out | `GatedVoxelOutput` only | never the raw `VoxelMap`; gated by `VoxelGate` | + +The tracker holds **no raw CSI** and **no payload bytes** — only scores, occupancy estimates, and the voxel grid. The only path to the network is through `VoxelGate::demote`. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Single orchestration point.** Five previously-isolated modules (`calibration`, `field_model`, `longitudinal`, `attractor_drift`, `tomography`) gain a coordinator that reads them together. Cross-link change-point detection becomes possible for the first time; no module was ever fed more than one link. +- **Temporal occupancy memory.** A 200-frame occupancy is now distinguishable from a single-frame noise spike via `evidence_count` and converged Bayesian log-odds. The fusion engine (ADR-137) gets per-voxel confidence instead of a binary snapshot threshold. +- **Mesh-wide freshness.** `field_model.rs::check_freshness` only knew one room; `EvolutionTracker` reduces per-link freshness to a mesh `CoherenceAlert`, closing the operational gap ADR-135's per-link drift score left open. +- **Internal contradiction detection.** The occupancy-consistency check turns two independent estimates (eigenstructure vs body-perturbation energy) into an `AnomalyWarn` that ADR-137 can score — a built-in sanity check the pipeline never had. +- **Privacy by construction.** No voxel grid reaches a network sink except through `VoxelGate::demote`, reusing the proven monotonic-demotion invariant from `bfld/src/privacy_gate.rs`. Doppler (the strongest gait-identity surface in a voxel grid) is cleared at Anonymous; the grid itself never leaves at Restricted. +- **Additive CIR integration.** The `CirDistancePrior` is optional; absent CIR, `tomography.rs` behaves identically and its existing tests are untouched. + +### 3.2 Negative + +- **New persistent state.** The `VoxelMap` is long-lived (one per monitored volume) and adds memory: an 8×8×4 grid is 256 voxels × ~40 bytes ≈ 10 KB — trivial — but a finer 16×16×8 grid is ~2,048 voxels and the decay loop runs every tick over all voxels. Bounded and cheap, but it is new always-on work at 20 Hz. +- **Energy-per-person scale is an install constant.** The occupancy-consistency check's `energy_per_person` is environment-specific and must be set at calibration time; a wrong value produces spurious `AnomalyWarn`s. It is derived from the same empty-room session as ADR-135's baseline. +- **Change-point window tuning.** The 30-frame / 3-link / 2σ defaults are reasoned from ADR-135's thresholds but not yet validated on real multi-room hardware; a noisy mesh could over-trigger `ChangePoint`. Mitigated by requiring majority-of-window hotness per link (§2.2), not a single hot frame. +- **Doppler is gated away early.** Useful kinematic information is cleared at Anonymous. This is intentional (it is the identity surface) but means trajectory analytics must run *before* the gate, inside the trusted node boundary, not on gated output. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| `ChangePoint` over-triggers on a noisy mesh (HVAC, sunlight) | Medium | Spurious mesh-recalibration prompts | Majority-of-window per-link hotness + 3-link minimum; ADR-135 drift-confirm still gates auto-recalibration | +| Bayesian voxel converges to a stale occupancy after a person leaves | Medium | A vacated voxel reads occupied for several seconds | Confidence decay with `decay_half_life` for un-updated voxels; the log-odds is pulled toward "free" by subsequent low-density observations | +| `VoxelGate` Anonymous quantisation still leaks coarse trajectory | Low | Re-identification from coarse grid over time | Restricted mode (histogram only) for untrusted sinks; ADR-141 control plane chooses class per sink | +| CIR distance prior misplaces evidence when the dominant tap is the direct path, not the body | Medium | Evidence concentrated at the wall, not the person | Prior is multiplicative on existing Fresnel weights (cannot create evidence where the ray does not pass); body-perturbation energy still gates whether a voxel is occupied at all | +| Occupancy-consistency false `AnomalyWarn` from a wrong `energy_per_person` | Medium | Noise into ADR-137 contradiction stream | Tolerance default of 1 person; calibrate `energy_per_person` during the empty-room session and re-derive on `ChangePoint` | + +--- + +## 4. Alternatives Considered + +### 4.1 Make `OccupancyVolume` Stateful In-Place (Rejected) + +The simplest path is to add `confidence`/`last_update_ns`/`evidence_count` fields directly to `tomography.rs::OccupancyVolume` and have `reconstruct()` mutate a retained instance. Rejected: `OccupancyVolume` is currently a pure output of `reconstruct()` and is cloned/inspected by tests that assume it is a snapshot (e.g. `test_zero_attenuation_empty_room` asserts `occupied_count == 0` for a fresh volume). Conflating snapshot and persistent state would break that contract and entangle the solver with temporal policy. The `VoxelMap` keeps the solver pure and the temporal state separate. + +### 4.2 One Tracker Per Link (Rejected) + +Keep the per-link isolation and run an independent tracker per link. Rejected: this is the *current* situation and is exactly what makes cross-link change-point and mesh freshness impossible. The whole value of an "evolution tracker" is the cross-link view. + +### 4.3 Kalman / Particle Filter Per Voxel (Rejected for Now) + +A per-voxel Kalman or particle filter would model occupancy *and* velocity jointly with a proper motion model. Rejected as overkill for a coarse 8×8×4 grid at the current sensing resolution: the log-odds occupancy grid is the standard, cheap, commutative choice (Thrun et al., 2005) and integrates trivially with the existing ISTA output. A motion-model filter belongs in the pose tracker (`pose_tracker.rs` already runs a 17-keypoint Kalman), not in the coarse occupancy grid. Revisit if voxel resolution increases materially. + +### 4.4 Emit Raw VoxelMap and Gate Downstream (Rejected) + +Let the raw `VoxelMap` leave the node and gate it at the consumer. Rejected on the same structural-invariant grounds as BFLD class 0 (`Raw` is local-only by invariant I1, `bfld/src/lib.rs`): once raw identity-leaky voxel data crosses a network boundary it cannot be un-leaked. Gating must happen *before* the sink, inside the node, which is exactly what `VoxelGate::demote` enforces. + +### 4.5 New Privacy Mechanism for Voxels (Rejected) + +Design a bespoke voxel-privacy scheme independent of BFLD. Rejected: the monotonic-demotion invariant in `privacy_gate.rs` is already proven and audited (ADR-120), and ADR-141 already defines the named-mode control plane. Reusing `PrivacyClass` and the `demote` pattern means one privacy model across the whole system, one set of attestation tests, and no second mechanism to audit. + +--- + +## 5. Testing and Acceptance + +### 5.1 Unit Tests + +**T1 — Mesh freshness aggregation.** Feed `LinkObservation`s with mixed `CalibrationStatus` (`Fresh`, `Stale`, `Expired`). Assert `mesh_freshness` is the worst case and `stale_links` lists exactly the non-fresh links, and a `CoherenceAlert` is emitted iff any link is Stale/Expired. + +**T2 — Cross-link change-point fires at 3 links.** Push 30-frame z-windows where exactly 2 links exceed 2.0σ for a majority of the window: assert no `ChangePoint`. Add a 3rd: assert `ChangePoint { links }` fires and names all three. + +**T3 — Change-point does NOT fire on a single sustained link.** One link hot for the full window, all others quiet: assert no `ChangePoint` (this is ADR-135's single-link staleness domain, not an environment change). + +**T4 — Occupancy-consistency.** Set `model_occupancy = 1`, supply body energy implying 1 person: assert no `AnomalyWarn`. Supply body energy implying 3 persons: assert `AnomalyWarn { model: 1, perturbation: 3 }` and `occupancy_disagreement == true`. + +**T5 — VoxelMap evidence accumulation.** Ingest 200 identical occupied volumes for one voxel and 1 occupied volume for another. Assert the 200-frame voxel has `evidence_count == 200`, `occupancy > 0.95`, and is NOT in `low_confidence_indices(5)`; the 1-frame voxel IS in `low_confidence_indices(5)` and has `occupancy` far from 1.0. + +**T6 — Low-confidence flagging at threshold.** Ingest exactly 4 frames for a voxel: assert it is low-confidence. Ingest a 5th: assert it leaves `low_confidence_indices(5)`. + +**T7 — Confidence decay.** Ingest a voxel to high confidence, then ingest `decay_half_life` ticks where that voxel is not touched: assert its `confidence` halved while `occupancy` (last estimate) is retained. + +**T8 — Per-voxel Welford variance.** Ingest densities `[0.9, 0.1, 0.9, 0.1, ...]` (noisy) vs `[0.5, 0.5, ...]` (steady) with equal mean: assert the noisy voxel has higher `density_variance()` and consequently lower `confidence`. + +**T9 — VoxelGate monotonicity.** `demote(map, Anonymous, Derived)` returns `BfldError::InvalidDemote { from: 2, to: 1 }`. `demote(map, Derived, Anonymous)` succeeds and the returned `VoxelMap` has every `doppler_velocity == 0.0` and `confidence == 0.0`. + +**T10 — VoxelGate Restricted emits no grid.** `demote(map, Anonymous, Restricted)` returns `GatedVoxelOutput::OccupancyHistogram` and never a `VoxelMap` — assert the variant is the histogram and its length equals the requested bucket count. + +**T11 — CIR prior is additive.** Run `RfTomographer::reconstruct()` with and without a `CirDistancePrior`; assert the no-prior path is bit-identical to current `tomography.rs` output (existing tests unchanged), and the with-prior path concentrates density nearer the CIR range. + +### 5.2 Integration Test (gated, `#[cfg(feature = "hardware-test")]`) + +**T12 — Real multistatic mesh (COM9 + cognitum-seed-1).** With an empty room, run 30 s and assert no `ChangePoint`, `mesh_freshness == Fresh`, and the `VoxelMap` has all voxels at `occupancy < 0.2`. Walk through: assert occupied voxels rise above 0.8 along the path, `evidence_count` grows, and walking *out* lets confidence decay. Move a chair and leave: assert a `ChangePoint` fires within 1.5 s and the affected links are named. + +### 5.3 Determinism / Witness (CI-compatible, extends ADR-028) + +**T13 — Deterministic VoxelMap hash.** Build a fixed 600-tick synthetic occupancy stream (seed=42), ingest into a `VoxelMap`, and SHA-256 the serialised voxel state. Record under `archive/v1/data/proof/expected_features.sha256` as `voxelmap_evidence_v1`; `verify.py` regenerates and asserts the hash. Mirrors ADR-135's `calibration_nvs_baseline_v1` proof methodology. + +### 5.4 Acceptance Criteria + +1. `EvolutionTracker::tick()` runs in < 1 ms for an 8×8×4 grid and 12 links (20 Hz budget is 50 ms; ample headroom). +2. Change-point fires iff ≥ `change_point_min_links` exceed `change_point_sigma` for a window majority (T2, T3). +3. A voxel below `min_evidence_frames` is always reported low-confidence (T5, T6). +4. No code path emits a raw `VoxelMap` to a network sink without `VoxelGate::demote` (enforced by the interface boundary in §2.7; `VoxelGate` is the only public constructor of `GatedVoxelOutput`). +5. `VoxelGate::demote` is monotonic: a promotion attempt always returns `BfldError::InvalidDemote` (T9). +6. Every emitted semantic state (occupancy + alerts) carries references to signal evidence (the `LinkObservation` set), model version (FieldModel SVD generation), calibration version (`BaselineCalibration.captured_at_unix_s`), and privacy decision (`VoxelGate` target class). +7. The CIR distance prior is provably additive — the no-prior reconstruction is unchanged (T11). + +--- + +## 6.

There is no `Reflector`, no `anchor`, no spatial position in the entire module. + +- **Localisation assumes fixed anchors.** `wifi-densepose-mat/src/localization/triangulation.rs` (`TriangulationConfig`, `Triangulator`, lines 7–88) takes `sensors: &[SensorPosition]` as given input and trilaterates a *person* from RSSI/ToA. `wifi-densepose-ruvector/src/mat/triangulation.rs::solve_triangulation()` (lines 28–53) takes `ap_positions: &[(f32, f32)]` as a fixed argument and solves a linearised TDoA system via `NeumannSolver`. Both treat anchor positions as configuration the operator must enter by hand. Neither has any path to *discover* an anchor (a static reflector or an AP) from the signal. + +- **The tracker tracks people, not furniture.** `wifi-densepose-mat/src/tracking/kalman.rs` (`KalmanState`, lines 26–35) is a 6-state constant-velocity filter for a *survivor* position. There is no per-reflector tracker, no notion of a slow-moving (furniture) versus fast-moving (person) target, and no displacement-rate estimate. + +- **`wifi-densepose-geo` has scene types but no RF objects.** `wifi-densepose-geo/src/types.rs` exposes `GeoPoint`, `GeoBBox`, `GeoRegistration`, `GeoScene`, `OsmFeature` — outdoor geospatial registration. There is no indoor reflector or anchor type. + +So the gap is precise: **the system can measure multipath delay per link and can tell static from dynamic energy, but it cannot place reflectors in a room coordinate frame, cannot decide which reflectors are stable enough to use as localisation anchors, and cannot notice when the furniture has moved.** ADR-030 (§the persistent field model) and ADR-042 (CHCI) both assume a known room geometry; neither specifies how that geometry is acquired. + +### 1.2 What "RF SLAM" Means Here (and What v1 Already Is) + +SLAM — Simultaneous Localisation And Mapping — in the RF-sensing context means: *while* tracking moving targets (localisation), also *build and refine* the map of static scatterers (mapping). This ADR is explicitly **v2**. There is a **v1** that this ADR commits to shipping *first*: + +- **RF SLAM v1 (ship now):** 3 fixed APs at operator-entered positions + a single static-reflector assumption. This is essentially what `triangulation.rs` and `solve_triangulation()` already do once the operator types in AP coordinates. v1 requires no new discovery code — it requires only wiring the fixed positions into the WorldGraph as immutable `object_anchor` nodes (ADR-139). v1 is honest about its limitation: it cannot adapt to a moved sofa. + +- **RF SLAM v2 (this ADR, feature-flagged):** infer reflector positions from CIR tap separation, learn which reflectors are stable enough to serve as anchors, detect topology change, and estimate furniture movement — all gated behind a feature flag until a 7-day validation dataset is collected. + +The reason for the two-tier rollout is the same reason ADR-135 makes recalibration operator-initiated: **there is no oracle for ground truth in a live home.** A reflector-discovery algorithm that places a wall 30 cm off does not announce its error; it silently degrades every downstream localisation. v2 must prove itself on 7 days of paired data before it is allowed to overwrite the v1 fixed map. + +### 1.3 Why CIR Tap Separation Gives Geometry + +For a link between TX at `p_tx` and RX at `p_rx`, a reflector at `p_r` produces a delayed copy of the direct path. The excess delay of that tap, relative to the direct (line-of-sight) tap, is: + +``` +Δτ = ( |p_tx − p_r| + |p_r − p_rx| − |p_tx − p_rx| ) / c +``` + +`Δτ` is exactly `(tap_idx − dominant_tap_idx) × tap_spacing_sec` from the `Cir` struct. A single link constrains the reflector to a **prolate spheroid** with foci at `p_tx` and `p_rx` (constant bistatic range = constant excess delay). Two links with shared geometry intersect their spheroids; three or more over-determine the reflector position and let least-squares resolve `(x, y, z)`. This is the dual of `solve_triangulation()` in `ruvector/mat/triangulation.rs`: that function solves for a person given fixed APs; reflector discovery solves for a static scatterer given the (now known, from v1) APs and the per-link excess-delay taps. + +The bistatic-range geometry only resolves a point if the multipath cluster is **persistent and coherent** across the observation window. Hence discovery is gated on temporal coherence (the same von Mises phase-concentration machinery from ADR-135) and on the room genuinely being in a static regime (the ADR-030 Marcenko-Pastur threshold — if `estimate_occupancy() > 0`, the room is occupied and discovery is suspended). + +### 1.4 Pipeline Position + +``` +Per-link CSI (ADR-135 baseline-subtracted, ADR-138 LinkGroup-grouped) + → CirEstimator::estimate() (ADR-134) → Cir { taps, ... } + → FieldModel.feed_calibration / SVD (ADR-030) → variance_explained, MP count + → ReflectorTracker::observe() ← NEW (rf_slam.rs) + · extract excess-delay taps per link + · associate taps to reflector tracks (per-reflector Kalman) + · bistatic multilateration → reflector (x,y,z) + covariance + · coherence-gate: accept only persistent, von-Mises-concentrated taps + → AnchorLearner::classify() ← NEW + · cluster persistent reflectors → walls / large objects + · reject mobile reflectors (tap migration > 0.5 m/day) + · emit StaticAnchor set + → TopologyMonitor::tick() ← NEW + · variance_explained drop > 15% / 4h OR covariance-rank change + → BaselineTopologyChange event → recalibration trigger (ADR-135 §2.6) + → FurnitureMovementEstimator::tick() ← NEW + · per-reflector tap-migration rate → hourly displacement ± 0.5 m + → WorldGraph::upsert(object_anchor) (ADR-139) → persisted via RVF +``` + +v2 discovery code (everything marked NEW) is compiled behind `#[cfg(feature = "rf-slam-v2")]` and is a no-op at runtime unless `RfSlamConfig::enabled` is also set. v1's fixed-AP map flows straight to `WorldGraph::upsert(object_anchor)` with immutable positions. + +--- + +## 2. Decision + +### 2.1 v2 Reflector Discovery from CIR Tap Separation + Temporal Coherence + +A reflector is discovered, not configured. The `ReflectorTracker` ingests one `Cir` per link per cycle (from ADR-138's `LinkGroup`, which guarantees the links it groups share a clock-quality tier so their delays are comparable) and maintains a set of reflector tracks. + +**Discovery preconditions (all must hold for a cycle to contribute to discovery):** + +1. **Room is static.** `FieldModel::estimate_occupancy()` (field_model.rs:741) returns 0 for the cycle's recent-frame window, *and* the ADR-030 Marcenko-Pastur significant-eigenvalue count equals the calibrated `baseline_eigenvalue_count`. If the room is occupied, the cycle is dropped for discovery (but still used for localisation). This reuses the existing eigenvalue gate rather than inventing a new occupancy detector. +2. **Tap is coherent over the window.** For a candidate tap index `g` on a link, the complex tap value `taps[g]` must have circular phase variance below `coherence_max` (default 0.15) over a rolling 24–72 h window, computed with the running `sin`/`cos` accumulator from ADR-135 §2.2 (von Mises projection). A tap whose phase wanders is a transient (a passing person's residual, an HVAC vane), not a static scatterer. +3. **Tap exceeds the noise floor.** `|taps[g]|` ≥ `1%` of the dominant tap — reusing the `active_tap_count` definition (cir.rs:278) so the discovery and CIR modules agree on what "a tap" is. + +**Multilateration.** Each accepted tap gives one bistatic-range constraint per link. With ≥3 links observing a common scatterer (associated by excess-delay consistency, §2.4), the reflector position is solved by the **same Neumann-series least-squares machinery** as person localisation — `wifi-densepose-ruvector/src/mat/triangulation.rs::solve_triangulation()` is generalised so it can be fed reflector bistatic ranges instead of person TDoA. The reflector position carries a 3×3 covariance from the residual. + +```rust +// v2/crates/wifi-densepose-signal/src/ruvsense/rf_slam.rs + +use num_complex::Complex32; +use crate::ruvsense::cir::Cir; +use crate::ruvsense::field_model::WelfordStats; + +/// A persistent static scatterer inferred from CIR tap separation. +#[derive(Debug, Clone)] +pub struct Reflector { + /// Stable identifier assigned at first confident discovery. + pub id: ReflectorId, + /// Estimated room-frame position (metres). `None` until ≥3 links concur. + pub position_m: Option<[f64; 3]>, + /// 3×3 position covariance (metres²), row-major. `None` until localised. + pub position_cov: Option<[[f64; 3]; 3]>, + /// Per-observing-link excess delay (s) relative to that link's direct tap. + pub excess_delay_s: Vec<(LinkId, f64)>, + /// Welford amplitude statistics of the tap magnitude over the window. + pub amp_stats: WelfordStats, + /// Circular phase variance over the window ∈ [0, 1]; <0.15 ⇒ coherent. + pub phase_circular_variance: f32, + /// Number of discovery cycles this reflector has been continuously observed. + pub persistence_cycles: u64, + /// First-seen / last-seen UTC (Unix seconds). + pub first_seen_unix_s: i64, + pub last_seen_unix_s: i64, +} + +#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)] +pub struct ReflectorId(pub u64); +#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)] +pub struct LinkId(pub u32); + +#[derive(Debug, thiserror::Error)] +pub enum RfSlamError { + #[error("RF SLAM v2 disabled (set RfSlamConfig.enabled and the rf-slam-v2 feature)")] + Disabled, + #[error("Room is occupied; discovery suspended for this cycle")] + RoomOccupied, + #[error("Insufficient observing links: need {needed}, have {got}")] + InsufficientLinks { needed: usize, got: usize }, + #[error("Multilateration failed to converge")] + NoConverge, + #[error("Validation dataset not yet present: {0}")] + ValidationGateClosed(String), +} + +#[derive(Debug, Clone)] +pub struct RfSlamConfig { + /// Master switch.

A wall is; a houseplant that sways is not; a chair that gets pushed in twice a day is not. The `AnchorLearner` partitions the reflector set into **static anchors** (usable for the v2 map) and **mobile reflectors** (tracked but excluded from the anchor set). + +**Classification rules:** + +| Class | Criterion | Rationale | +|-------|-----------|-----------| +| `StaticAnchor` | `phase_circular_variance < coherence_max` AND tap-migration rate `< mobile_reject_m_per_day` (0.5 m/day) AND `persistence_cycles` spans ≥ 24 h | Walls and large fixed objects (cabinet, fridge) produce a coherent tap whose position does not drift day to day. | +| `MobileReflector` | tap-migration rate ≥ 0.5 m/day | Furniture that is rearranged; tracked for movement inference (§2.4) but never used as a localisation anchor because its position is not trustworthy as a reference. | +| `TransientCandidate` | `phase_circular_variance ≥ coherence_max` OR `persistence_cycles` < 24 h | Not yet confident; held in a candidate buffer, promoted or aged out. | + +**Spatial clustering into furniture categories.** Static anchors are clustered in room-frame `(x, y, z)` using density-based clustering (DBSCAN-style, `ε = 0.3 m`, `minPts = 2`).

When the furniture map shifts, the calibrated modes no longer fit and `variance_explained` falls. **Trigger: a relative drop > 15% sustained over a 4-hour window.** (Relative, not absolute — a room with `variance_explained = 0.8` dropping to `0.68` is the same proportional shift as `0.5 → 0.425`.) +2. **Covariance rank change.** The Marcenko-Pastur significant-eigenvalue count (`baseline_eigenvalue_count`, field_model.rs:278/589) is the structural rank of the static channel. A new fixed scatterer adds a mode; a removed one drops a mode. A *sustained* change in the MP count while the room is unoccupied (occupancy gate from §2.1) indicates a topology change, not a person. + +Both conditions feed a `TopologyMonitor` that, on confirmed change, emits `BaselineTopologyChange` and routes it to the **existing** recalibration trigger described in ADR-135 §2.6 (`recalibrate_on_drift`). v2 does not invent a second recalibration path; it provides a more specific *cause* (topology change vs amplitude drift) than ADR-135's amplitude-only z-score drift. + +```rust +#[derive(Debug, Clone)] +pub enum TopologyEvent { + /// variance_explained dropped > config.topology_var_drop over the window. + VarianceCollapse { from: f64, to: f64, window_h: f64 }, + /// Marcenko-Pastur significant-eigenvalue count changed while unoccupied. + RankChange { from: usize, to: usize }, +} + +pub struct TopologyMonitor { config: RfSlamConfig, /* rolling history */ } + +impl TopologyMonitor { + pub fn new(config: RfSlamConfig) -> Self; + + /// Feed the current field-model summary for this cycle. + /// Returns `Some(event)` when a topology change is confirmed. + pub fn tick( + &mut self, + variance_explained: f64, + mp_significant_count: usize, + occupied: bool, + now_unix_s: i64, + ) -> Option; +} +``` + +### 2.4 Furniture-Movement Inference + +A `MobileReflector` is not noise — its *displacement over time* is information ("the chair moved 0.4 m at 14:00"). The `FurnitureMovementEstimator` tracks each reflector's tap-migration rate and emits hourly displacement estimates with a **0.5 m confidence band**, using ADR-042 CHCI cross-link consistency to reject spurious migrations. + +**Per-reflector position tracking.** Each reflector gets a slow-dynamics Kalman filter. We **reuse the constant-velocity `KalmanState` from `wifi-densepose-mat/src/tracking/kalman.rs`** (the same 6-state `[px,py,pz,vx,vy,vz]` filter used for survivors, kalman.rs:26) but parameterised for furniture timescales: a tiny process-noise variance (`process_noise_var ≈ 1e-6 (m/s²)²`, vs the human-tracking value) so the filter only believes motion that persists across many hours. The velocity components, integrated over an hour, give the hourly displacement. + +**CHCI cross-link consistency gate.** A genuine furniture move shifts the excess-delay tap *consistently* across every link that observes that reflector (the geometry changes for all of them coherently). A spurious migration (multipath self-interference, a transient) shows up on one link only. ADR-042's coherent cross-link phase machinery scores this consistency: a displacement is emitted only if ≥ `min_links` links agree on the direction of tap migration within the 0.5 m band.

The value is realised only after a validation campaign on the fleet. +- **Bistatic multilateration needs ≥ 3 well-separated links.** A 1- or 2-link room can never resolve reflector positions (the spheroids do not intersect to a point). Such rooms are permanently v1-only.

Alternatives Considered + +### 4.1 Visual / Camera SLAM for the Room Map + +The fleet has cameras (`ruvultra`, `cognitum-v0`). Camera SLAM would map furniture far more accurately. Rejected as the *primary* mechanism because: (a) the entire product premise is privacy-preserving RF sensing — adding a camera to map the room contradicts the ADR-141 BFLD privacy modes; (b) cameras do not see through walls, so they cannot characterise reflectors behind furniture that nonetheless affect the RF channel. Camera ground truth is, however, exactly what the §2.7 validation dataset uses — as an *offline validation oracle*, not a runtime dependency. + +### 4.2 Full Graph-SLAM / Factor-Graph Back-End (g2o / GTSAM style) + +A factor-graph back-end jointly optimising all reflector positions, anchor poses, and person trajectories is the "textbook" SLAM formulation. Rejected for v2 scope: it is a large new dependency and solver, and the per-reflector Kalman + per-cycle least-squares multilateration already in the codebase (`kalman.rs` + `NeumannSolver`) is sufficient for a static-scene map that changes only on rare furniture moves. A factor-graph back-end is reasonable for a v3 once v2 proves the discovery front-end works. + +### 4.3 Neural Reflector Inference + +Train a network to regress reflector positions from CIR. Rejected for the same reason ADR-135 §4.3 rejects neural baselines: no paired CIR→geometry dataset exists, the mapping is room-specific, and a network gives no covariance or failure mode. Bistatic multilateration is a closed-form geometric estimator with an explicit covariance and a clear "insufficient links" failure. + +### 4.4 Skip v1, Ship v2 Directly + +Tempting — v2 is strictly more capable. Rejected because v2 is unvalidated and silently degrades on error (§1.2). Shipping the fixed-AP v1 gives a working, debuggable baseline that the v2 discovery can be measured *against*, and gives users a functioning system during the multi-day v2 validation campaign. + +### 4.5 EMA-Adapted Anchor Positions Instead of Discrete Topology Events + +Continuously sliding anchor positions with an exponential moving average avoids the topology-change ceremony. Rejected for the same reason ADR-135 §4.4 rejects EMA for baselines: a person standing near a wall would slowly drag the wall's "anchor" toward them. Anchors must be stable between explicit topology events, not continuously adapted. + +--- + +## 5. Testing and Acceptance + +### 5.1 Unit Tests (CI, synthetic — no hardware, no feature gate needed for the math) + +- **T1 — bistatic geometry round-trip.** Place a synthetic reflector at a known `(x,y,z)`; compute the exact excess delay for 4 synthetic links; feed taps to `ReflectorTracker::observe()`; assert recovered `position_m` is within `0.05 m` (numerical, noise-free) and `position_cov` is small. +- **T2 — sub-3-link insufficiency.** Same reflector, only 2 links → `observe()` leaves `position_m == None`, no `StaticAnchor` emitted. +- **T3 — coherence gate.** A tap whose synthetic phase is randomised (circular variance ≈ 1.0) is never promoted to `StaticAnchor` regardless of link count. +- **T4 — mobile rejection.** A reflector whose synthetic position drifts 1.0 m/day is classified `MobileReflector`, never `StaticAnchor` (validates the 0.5 m/day threshold). +- **T5 — occupancy gate.** With `occupied = true`, `observe()` returns `RoomOccupied` and mutates no track. +- **T6 — topology variance collapse.** Feed `variance_explained` dropping from 0.80 → 0.66 (17.5% relative) sustained 4 h, unoccupied → exactly one `VarianceCollapse` event; a 10% drop produces none. +- **T7 — topology rank change.** MP significant count 5 → 6 sustained while unoccupied → one `RankChange` event. +- **T8 — furniture displacement + CHCI consistency.** A reflector moved 0.4 m consistently across ≥3 links → one `DisplacementEstimate` with `confidence_radius_m ≤ 0.5`; the same migration on 1 link only → suppressed (no estimate). +- **T9 — WorldGraph record provenance.** `ObjectAnchorRecord` always carries non-empty `discovery_model_version`, `calibration_version`, `privacy_decision`, and `evidence_refs` (enforces the four-part trace rule). +- **T10 — validation gate.** `enabled = true` without the validation manifest → `ValidationGateClosed`; `enabled = false` → `Disabled`. v1 path still populates the WorldGraph with immutable fixed-AP anchors in both cases. +- **T11 — person-localisation regression.** Generalised `solve_triangulation()` produces byte-identical output to the pre-change version for the existing person-TDoA test vectors. + +### 5.2 Integration Test (gated `#[cfg(feature = "hardware-test")]`, not in CI) + +- **T12 — 7-day fleet validation campaign.** On `cognitum-v0` room with ≥3 provisioned seeds: collect the §2.7 dataset, run discovery, and assert the four pass criteria. This test *is* the validation gate; passing it is the precondition for setting `RfSlamConfig::enabled` in production config. + +### 5.3 Acceptance Criteria (mirror §2.7) + +1. ≥ 80% of discovered `StaticAnchor`s within **0.5 m** of tape-measured ground truth. +2.

Context + +### 1.1 The Gap + +WiFi CSI sensing in this codebase produces *relative* perturbation fields, not *metric* position. The pose tracker estimates 3D keypoint coordinates from those fields, but the only thing anchoring those coordinates to real-world metres is the geometry assumed at calibration time. There is no independent metric ranging source to correct scale drift, resolve the front/back ambiguity inherent in a single multistatic array, or disambiguate two tracks that cross. UWB (ultra-wideband, IEEE 802.15.4z) two-way ranging gives exactly that: a direct, hardware-grounded distance measurement with ±10 cm accuracy that is *orthogonal* to the CSI evidence. + +Searching the workspace confirms there is no UWB support anywhere: + +- `grep -ri "uwb\|802.15.4z\|two_way_ranging\|RangeConstraint" v2/crates/` returns nothing in production code. The only `802.15.4` reference is the *timesync* epoch on the ESP32-C6 (`c6_timesync_get_epoch_us()`, ADR-110), which is a clock primitive, not a ranging primitive. +- `v2/crates/wifi-densepose-hardware/src/` contains parsers for ESP32 CSI (`esp32_parser.rs`, ADR-018 magic `0xC5110001`), sibling RuView packets (`RUVIEW_VITALS_MAGIC` … `RUVIEW_TEMPORAL_MAGIC`), a UDP aggregator (`aggregator/`), a `bridge.rs` (`CsiFrame → CsiData`), and the radio-ops mirror (`radio_ops.rs`). Every magic constant in `esp32_parser.rs` is a *CSI-family* packet. There is no range/anchor frame type and no anchor-bearing device abstraction. +- `v2/crates/wifi-densepose-signal/src/ruvsense/pose_tracker.rs` (the 17-keypoint Kalman tracker, ADR-029 §2.7) has a position-only measurement model: `KeypointState::update()` takes `&[f32; 3]` and `KeypointState::mahalanobis_distance()` gates a *Cartesian* measurement. There is **no mechanism to apply a range constraint** — a measurement of the form "the centroid is `r ± σ` metres from a fixed anchor" — which is a nonlinear (spherical) observation, not a Cartesian one. `PoseTrack` has no field for accumulated range residuals. +- `v2/crates/wifi-densepose-mat/src/localization/fusion.rs` has a `PositionFuser` with an `EstimateSource` enum (`RssiTriangulation`, `TimeOfArrival`, `AngleOfArrival`, `CsiFingerprint`, `DepthEstimation`, `Fused`) and `Triangulator` that consumes RSSI. There is **no `TimeOfArrival` producer** — `EstimateSource::TimeOfArrival` is defined but nothing emits it, and `LocalizationService::simulate_rssi_measurements()` explicitly returns `vec![]` with a warning "No sensor hardware connected." The fusion machinery exists; the metric-ranging input does not. + +The consequence is concrete. Three failure modes trace directly to the missing metric anchor: + +- **Scale and front/back ambiguity in single-array sensing.** A monostatic or near-colinear multistatic CSI array cannot distinguish a person 2 m in front from a (geometrically mirrored) reflection 2 m behind without strong geometric diversity (ADR-029's `geometry.rs` Fisher-information bounds quantify exactly when this fails). A single UWB range to a known anchor collapses that ambiguity for the constrained dimension. +- **Track-crossing identity swaps.** When two `PoseTrack`s pass within the Mahalanobis gate of each other, assignment falls back to AETHER re-ID cosine similarity (`pose_tracker.rs` `embedding_weight = 0.4`). Re-ID alone is unreliable for similar body shapes. A UWB tag worn by one person (or a range that is consistent with only one of the two crossing tracks) breaks the tie deterministically. +- **No metric ground truth for the WorldGraph.** ADR-139's WorldGraph stores object anchors and person tracks as typed nodes; without a metric edge between them, anchor positions are never corrected and the digital twin slowly drifts from physical reality. + +ADR-063 (mmWave Sensor Fusion, Accepted) already establishes the *pattern* for fusing an orthogonal ranging modality (60 GHz FMCW range/Doppler) with CSI, and `RUVIEW_FUSED_VITALS_MAGIC` (`0xC5110004`) is the on-wire fused packet. ADR-144 follows that established fusion pattern but for UWB metric range rather than mmWave radial velocity, and it routes the result through the WorldGraph (ADR-139) as a first-class graph edge rather than a flat fused packet. + +### 1.2 What a "Range Constraint" Is Here + +A UWB range constraint is a single scalar metric measurement plus its provenance: + +- A measured line-of-sight distance `r` in metres between a fixed **anchor** of known position and a moving **tag/responder**, obtained by 802.15.4z single- or double-sided two-way ranging (SS/DS-TWR) or, where a synchronized anchor mesh exists, time-difference-of-arrival (TDoA). +- An uncertainty `σ_r` derived from the UWB module's reported first-path SNR / link quality. Clean LOS yields ~±10 cm; NLOS (through a wall) biases the range *long* and inflates `σ_r`. +- A timestamp in the same 802.15.4 epoch domain already used for multi-node CSI sync (ADR-110), so a range can be associated with the CSI frame closest in time. + +What a range constraint is **not**: it is not a position. One range defines a *sphere* of possible tag positions centred on the anchor. Position emerges only when a range is *fused* with the CSI-derived track state (which already carries a 3D estimate and covariance). This is the core reason the fusion lives in `pose_tracker.rs`'s Kalman update rather than as a standalone trilateration solver: the CSI track *is* the prior, and the range *tightens* it. + +### 1.3 Hardware Context + +UWB is a separate radio from WiFi. Three deployment forms are evaluated (Decision §2.3); the working assumption is a **standalone ESP32-C6 + DW3000-class UWB transceiver bridge node** that speaks the existing ADR-018 UDP transport: + +| Form factor | Radio | Role | Wire path | Cost | +|-------------|-------|------|-----------|------| +| Standalone UWB anchor (ESP32-C6 + Qorvo DW3000) | 802.15.4z UWB + 802.15.4 timesync | Fixed anchor, ranges to tags | New UDP magic frame over existing aggregator | ~$18 | +| Integrated radio (ESP32-C6 doing CSI *and* UWB on one node) | shared MCU | CSI sensing node that also ranges | Same node, interleaved magic | ~$15 (no extra node) | +| Bridge node (UWB-only MCU → serial → Pi 5) | DW3000 dev board | Anchor mesh, host does ranging math | `aggregator/` ingest | ~$25 | + +All three converge on the **same host-side abstraction**: a stream of `UwbRangeFrame`s with `(anchor_id, tag_id, range_m, quality, epoch_us)`. The hardware abstraction layer (HAL) hides which form factor produced the frame, exactly as `esp32_parser.rs` hides whether CSI came from an S3 or a C6. The C6's existing `c6_timesync_get_epoch_us()` (±100 µs) is reused so UWB ranges and CSI frames share one clock. + +### 1.4 Pipeline Position + +``` +UWB anchor/tag (802.15.4z TWR) + → UwbFrameParser::parse() ← NEW (wifi-densepose-hardware, ADR-018-style magic) + → RangeConstraint { anchor_id, range_m, σ, epoch_us, quality } ← NEW domain model + → WorldGraph::upsert_range_edge() ← NEW edge (ADR-139), object_anchor → person_track + │ + │ (association: which track does this range belong to?) + │ Mahalanobis-to-sphere gate + AETHER re-ID disambiguation + ▼ + → PoseTracker::apply_range_constraint() ← NEW (constraint-aware Kalman update) + │ + ▼ +CSI-only track state ─────────┐ + ├──→ LocalizationService (mat/fusion.rs) + │ EstimateSource::TimeOfArrival now PRODUCED + ▼ + fused metric track (with constraint residual + confidence) +``` + +CSI flows down the existing pipeline unchanged. The UWB range enters as a *parallel* evidence stream, is associated to a track, and is applied as an extra Kalman update step *after* the normal CSI measurement update. If no range arrives in a given cycle, the tracker behaves exactly as today — UWB is strictly additive. + +--- + +## 2. Decision + +### 2.1 The `RangeConstraint` Domain Model + +A `RangeConstraint` is the canonical, hardware-agnostic representation of one UWB range, defined in `wifi-densepose-hardware` (alongside `CsiFrame`) and re-exported for `signal` and `mat`. It carries enough provenance to satisfy the project rule that every semantic state traces to signal evidence + model version + calibration version + privacy decision. + +```rust +use std::time::Duration; + +/// Stable identifier for a fixed UWB anchor of known position. +#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)] +pub struct AnchorId(pub u32); + +/// Stable identifier for a mobile UWB tag / responder (may be a worn tag +/// or an unlabelled responder discovered during ranging). +#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)] +pub struct TagId(pub u32); + +/// Source of the metric range measurement. +#[derive(Debug, Clone, Copy, PartialEq, Eq)] +pub enum RangeMethod { + /// Single-sided two-way ranging (one round trip; clock-offset sensitive). + SsTwr, + /// Double-sided two-way ranging (cancels clock offset; preferred). + DsTwr, + /// Time-difference-of-arrival against a synchronized anchor mesh. + Tdoa, +} + +/// One UWB metric range measurement with full provenance. +/// +/// Defines a *sphere* of possible tag positions of radius `measured_range_m` +/// centred on the anchor at `AnchorId`.

Rejecting low-quality ranges discards information; inflating their variance lets the Kalman filter down-weight them gracefully, which is the same philosophy ADR-135 used for multimodal-phase subcarriers (down-weight, do not drop). + +### 2.2 WorldGraph Anchor Construction (ADR-139 Integration) + +ADR-139's WorldGraph is a typed petgraph whose nodes include `object_anchor` and `person_track`. A `RangeConstraint` becomes a **typed, weighted, timestamped edge** between an `object_anchor` node (the UWB anchor's fixed position) and a `person_track` node (a `PoseTrack`). + +```rust +/// Edge payload stored on a WorldGraph object_anchor → person_track edge. +#[derive(Debug, Clone)] +pub struct RangeEdge { + pub anchor_id: AnchorId, + pub track_id: TrackId, + pub constraint: RangeConstraint, + /// Mahalanobis distance of this range to the track's predicted sphere + /// at association time (the association cost, see §2.4). + pub assoc_cost: f32, + /// Provenance triple required by the SSR rule (ADR-140): + pub signal_evidence_id: u64, // CSI frame seq that the track state came from + pub model_version: u32, // pose/embedding model version + pub anchor_survey_version: u32, // anchor-registration ("calibration") version +} +``` + +The anchor node carries its surveyed 3D position and an `anchor_survey_version` that plays the same role for UWB that `schema_version`/`captured_at` plays for the ADR-135 baseline: a change to anchor geometry invalidates downstream range fusions tagged with the old survey version. The WorldGraph gains: + +```rust +impl WorldGraph { + /// Register or update a fixed anchor with a surveyed position. + /// Bumps `anchor_survey_version` and marks all RangeEdges from this + /// anchor stale. + pub fn register_anchor(&mut self, id: AnchorId, pos: [f32; 3]) -> u32; + + /// Insert a range constraint as an object_anchor → person_track edge. + /// Returns Err if `anchor_id` is not registered. + pub fn upsert_range_edge(&mut self, edge: RangeEdge) -> Result<(), WorldGraphError>; + + /// All current range edges incident to a track (for the Kalman update). + pub fn range_edges_for(&self, track: TrackId) -> Vec<&RangeEdge>; +} +``` + +Anchor positions are surveyed once and stored on the graph; this is the *anchor-registration policy* decision (§2.7). The WorldGraph is the single source of truth for anchor geometry so that `pose_tracker.rs` and `mat/fusion.rs` never disagree about where an anchor is. + +### 2.3 UWB Hardware Abstraction Layer (ADR-018 Wire-Format Pattern) + +A new module set in `wifi-densepose-hardware/src/` mirrors the `esp32_parser.rs` design: a magic-tagged binary frame over the existing UDP aggregator, a pure-bytes parser that never fabricates data, and an auto-detect that demultiplexes by magic. + +```rust +/// UWB range frame magic (ADR-144), next in the 0xC511xxxx family after +/// RUVIEW_TEMPORAL_MAGIC (0xC5110007). Demultiplexed alongside CSI frames. +pub const UWB_RANGE_MAGIC: u32 = 0xC5110008; + +/// ADR-018-style binary layout (little-endian): +/// 0 4 Magic 0xC5110008 +/// 4 4 anchor_id (u32) +/// 8 4 tag_id (u32; 0 = unlabelled responder → None) +/// 12 4 range_mm (u32; millimetres, converted to f32 metres) +/// 14 ...

Rationale: (a) it reuses the C6's `c6_timesync_get_epoch_us()` so UWB ranges land in the *same clock* as CSI frames with no new timesync work; (b) it reuses the ADR-018 UDP aggregator, so no new transport, no new firmware OTA channel, no new port; (c) integrating UWB onto an existing CSI node (form 2) is a strict superset — the same parser handles its frames. The aggregator's existing demultiplex loop gains one arm: `if UwbFrameParser::is_uwb_frame(buf) { … } else if Esp32CsiParser` (the same `else if` ladder already used for the seven `RUVIEW_*_MAGIC` sibling packets). + +**Interface boundary:** `wifi-densepose-hardware` owns parsing and the `RangeConstraint`/`AnchorId`/`TagId` types. It has **no dependency** on `signal` or `mat` — the dependency arrows point the other way, consistent with the crate publishing order (`hardware` has no internal deps; `signal` depends on `core`; `mat` depends on `signal`). + +### 2.4 Constraint-to-Track Association (AETHER Re-ID Disambiguation) + +A range from an unlabelled responder (`tag_id = None`) must be assigned to one of the live `PoseTrack`s before it can be applied. Labelled tags (`tag_id = Some(_)`) that have been bound to a track skip association. For unlabelled ranges, association uses a gated cost that mirrors the existing `pose_tracker.rs` assignment cost (`position_weight * maha + embedding_weight * embed_cost`) but with the *spherical* residual: + +For each candidate track `T` with predicted centroid `c_T` and anchor at `a`: + +``` +sphere_residual(T) = | ‖c_T − a‖ − measured_range_m | (metres off the sphere) +maha_sphere(T) = sphere_residual(T) / sqrt(var_radial(T) + constraint.variance()) +assoc_cost(T) = range_pos_weight * maha_sphere(T) + + range_reid_weight * reid_ambiguity(T) +``` + +where `var_radial(T)` is the track's positional variance projected onto the anchor→centroid line (computed from the existing `KeypointState::covariance` diagonal), and `reid_ambiguity(T)` is invoked **only when two or more tracks are within the spherical Mahalanobis gate** — i.e. equidistant-from-anchor crossing tracks. In that case the range is associated to the track whose AETHER embedding best matches the tag's last-known embedding (for labelled tags) or whose recent CSI-only association confidence is highest (for unlabelled). This reuses `cosine_similarity()` and the 128-dim embedding already on `PoseTrack`. + +```rust +/// Result of associating one RangeConstraint to the live track set. +pub enum RangeAssociation { + /// Uniquely associated (single track inside the gate). + Assigned { track: TrackId, cost: f32 }, + /// Multiple tracks inside the gate; resolved by AETHER re-ID. + AmbiguousResolved { track: TrackId, runner_up: TrackId, margin: f32 }, + /// No track inside the spherical Mahalanobis gate — range buffered, + /// not applied (may seed a new track if persistent). + Unassigned, +} +``` + +`Unassigned` ranges are not discarded — a persistent unassigned range that is geometrically consistent over several cycles is evidence of a person the CSI array has not yet detected (e.g. behind a piece of furniture), and is surfaced to the WorldGraph as a low-confidence latent track candidate. This is the UWB analogue of ADR-135 logging drift rather than silently dropping it. + +### 2.5 Constraint-Aware Kalman Update (`pose_tracker.rs`) + +The current `KeypointState::update()` is a *linear* Cartesian update (`H = [I3 | 0]`). A range is a *nonlinear* spherical observation `h(x) = ‖x − a‖`. We apply it as an **Extended Kalman (EKF) measurement update on the track centroid**, then distribute the centroid correction back to the keypoints proportionally — rather than rebuilding the whole tracker as a factor graph. + +**Algorithm decision: EKF spherical update with Mahalanobis gating and quality-weighted noise** (chosen over factor-graph batch optimization and over pure Mahalanobis gate-and-penalty; see §3 Alternatives). The centroid `c` already exists (`PoseTrack::centroid()`). For an anchor at `a`: + +``` +h(c) = ‖c − a‖ (predicted range) +H = (c − a)ᵀ / ‖c − a‖ (1×3 Jacobian, unit LOS vector) +y = measured_range_m − h(c) (scalar innovation) +S = H P_c Hᵀ + R where R = constraint.variance() (NLOS-inflated) +K = P_c Hᵀ S⁻¹ (3×1 gain) +c' = c + K y +P_c' = (I − K H) P_c +``` + +`P_c` is the 3×3 centroid covariance assembled from the per-keypoint covariance diagonals. After the centroid is corrected by `K y`, the same translational delta `(c' − c)` is added to every keypoint position and the radial variance reduction is applied to each keypoint's covariance, so the skeleton moves rigidly toward the constraint sphere without distorting its shape. This composes cleanly with the existing CSI update: CSI runs first (full skeleton update), then the range update nudges the whole skeleton onto the sphere. + +The constraint update is **gated**: if `|y| / sqrt(S) > range_gate` (default 3.0, matching the existing chi-squared 3-sigma philosophy of `mahalanobis_gate = 9.0`), the range is rejected for this cycle and recorded as a residual outlier rather than applied — preventing a wild NLOS range from teleporting a track. + +New state on `PoseTrack` (extending the struct, never replacing existing fields): + +```rust +/// Range-constraint history appended to PoseTrack (bounded ring buffer). +#[derive(Debug, Clone, Default)] +pub struct ConstraintTrackState { + /// Recent constraints applied to this track (bounded; e.g. last 32). + pub buffer: VecDeque, + /// Last applied scalar range residual (metres, signed). + pub last_constraint_residual: f32, + /// Gate status of the most recent constraint. + pub constraint_gate_status: ConstraintGateStatus, + /// Distinct anchors that have contributed a range to this track. + pub fused_range_sources: Vec, +} + +#[derive(Debug, Clone, Copy, PartialEq, Eq, Default)] +pub enum ConstraintGateStatus { + #[default] + /// No range applied this cycle. + None, + /// Range passed the gate and was fused. + Accepted, + /// Range exceeded the gate; recorded as outlier, not applied. + RejectedOutlier, + /// Range applied with NLOS-inflated variance (low quality). + AcceptedNlos, +} +``` + +```rust +impl PoseTracker { + /// Apply one associated range constraint to a track via the spherical + /// EKF update above.

Defaults are off-path-safe: with no range frames, none of this code executes and the tracker is byte-for-byte its current behaviour. + +### 2.6 `mat/fusion.rs` Integration + +`EstimateSource::TimeOfArrival` (already defined, currently unproduced) becomes the producer slot for UWB-derived metric position. `LocalizationService` gains an optional UWB path so the MAT survivor-localization use case (rubble ranging) and the ambient-sensing use case share one fusion implementation: + +```rust +impl LocalizationService { + /// Produce a TimeOfArrival PositionEstimate from a set of range + /// constraints to surveyed anchors (≥3 for full 3D, fewer constrains a + /// subspace). Replaces the empty simulate_rssi_measurements() path when + /// real UWB anchors are present. + pub fn estimate_from_ranges( + &self, + ranges: &[(Coordinates3D /*anchor*/, RangeConstraint)], + ) -> Option; +} +``` + +The resulting `PositionEstimate { source: EstimateSource::TimeOfArrival, weight: f(signal_quality), .. }` flows into the existing `PositionFuser::fuse()`, whose `calculate_weight()` already ranks `TimeOfArrival` highest (`1.0`). UWB thus slots into a fusion ranking the codebase already encodes — no new fuser, only a new producer. This keeps the MAT crate's domain model intact. + +### 2.7 Anchor-Registration Policy + +**Decision: manual survey as the authoritative source, with optional auto-learn from track geometry as a *proposal* the operator confirms.** + +- **Manual survey (default, authoritative).** The operator measures each anchor's 3D position once and calls `WorldGraph::register_anchor()`. This sets `anchor_survey_version`. This is the UWB analogue of ADR-135's operator-initiated calibration: there is no way to know an anchor's true position from the data alone with the accuracy fusion needs, so the system does not guess by default. +- **Auto-learn (opt-in, proposal only).** When ≥3 anchors range the *same* moving tag over a trajectory with sufficient geometric diversity (the Fisher-information criterion from ADR-029 `geometry.rs`), the anchor positions become observable up to a rigid transform. An offline solver can *propose* refined anchor positions, but they are applied only after the operator accepts — never silently — for the same reason ADR-135 refuses automatic recalibration: a self-modified anchor that is wrong corrupts every downstream fusion invisibly. + +Either path bumps `anchor_survey_version`, which invalidates `RangeEdge`s tagged with the old version, mirroring ADR-135's stale-baseline invalidation. + +### 2.8 Provenance and the SSR Rule + +Every fused metric position is a semantic state and therefore carries the full provenance triple (ADR-140 SSR / ADR-141 privacy): + +- **Signal evidence** — `RangeEdge.signal_evidence_id` (CSI frame sequence the track prior came from) + the `RangeConstraint.timestamp_us` of the UWB range. +- **Model version** — `RangeEdge.model_version` (pose + AETHER embedding model). +- **Calibration version** — `RangeEdge.anchor_survey_version` (anchor geometry survey). +- **Privacy decision** — UWB ranging reveals the *presence and distance of a tag-bearing person*, which is identity-adjacent. A range fusion is gated by the active BFLD privacy mode (ADR-141): in privacy modes that forbid identity binding, labelled `tag_id` association is suppressed and ranges are applied only as anonymous spherical constraints (no re-ID disambiguation, no tag→track binding stored). + +### 2.9 Test Plan and Acceptance Criteria + +**Tier 1 — Parser round-trip (unit test).** Encode a `RangeConstraint` to the §2.3 binary layout, parse with `UwbFrameParser::parse()`, assert field equality. Assert `is_uwb_frame()` returns `true` for `UWB_RANGE_MAGIC` and `false` for `ESP32_CSI_MAGIC` and all seven `RUVIEW_*_MAGIC`. Assert a truncated buffer yields `ParseError::InsufficientData` (no fabricated range). + +**Tier 2 — Spherical EKF correctness (unit test).** Place a track centroid at `(2,0,0)` with a known `P_c`; supply a range of `1.8 m` to an anchor at the origin (true distance 2.0). Assert the corrected centroid moves *along the LOS toward the sphere* by approximately `K·y`, that `P_c` shrinks in the radial direction, and that the skeleton shape (inter-keypoint distances) is unchanged to f32 precision (rigid translation). + +**Tier 3 — Gate rejection (unit test).** Same track; supply a range of `8.0 m` (4 m innovation, far beyond gate). Assert `apply_range_constraint()` returns `ConstraintGateStatus::RejectedOutlier`, the centroid is **unchanged**, and `last_constraint_residual` records the outlier. + +**Tier 4 — Crossing disambiguation (unit test).** Two tracks at `(2,0,0)` and `(0,2,0)`, both ~2 m from an anchor at the origin (equidistant → both inside the spherical gate). Track A's embedding matches the tag's last embedding (cosine ≈ 0.95), Track B's does not (≈ 0.1). Assert association returns `AmbiguousResolved { track: A, .. }` with positive `margin`. + +**Tier 5 — NLOS inflation (unit test).** A range with `signal_quality = 0.2` (NLOS). Assert `RangeConstraint::is_los(0.6) == false`, that `variance()` is inflated, and that the EKF gain `K` is correspondingly smaller than for a clean LOS range of the same innovation → status `AcceptedNlos`. + +**Tier 6 — WorldGraph edge lifecycle (unit test).** Register an anchor → `upsert_range_edge()` → `range_edges_for(track)` returns it. Call `register_anchor()` again (re-survey) → assert `anchor_survey_version` bumps and stale edges are flagged. + +**Tier 7 — `mat/fusion.rs` producer (unit test).** Feed three anchor+range pairs to `estimate_from_ranges()`; assert it yields a `PositionEstimate` with `source == EstimateSource::TimeOfArrival` and that `PositionFuser::fuse()` weights it at least as high as a co-located `RssiTriangulation` estimate. + +**Tier 8 — Off-path no-op (regression test).** Run the existing `pose_tracker` test suite with `range_*` config at defaults and **zero** range frames; assert every existing assertion passes unchanged (UWB is strictly additive). + +**Tier 9 — Determinism proof (CI-compatible, extends ADR-028).** A fixed synthetic trajectory + fixed range sequence (seeded) is fused; the SHA-256 of the resulting fused track positions is recorded in `archive/v1/data/proof/expected_features.sha256` under `uwb_range_fusion_v1`, and `verify.py` regenerates and asserts it. Adds witness rows to `docs/WITNESS-LOG-028.md` for parser round-trip, spherical EKF, and crossing disambiguation; `source-hashes.txt` gains the new parser and the `pose_tracker.rs` constraint additions. + +**Tier 10 — Real hardware (integration, gated `#[cfg(feature = "hardware-test")]`).** With one DW3000 anchor and a tag walked along a measured 4 m path, assert fused track range tracks the tape-measured ground truth to < 15 cm RMS in LOS and that NLOS segments (tag behind a wall) inflate uncertainty rather than producing > 30 cm errors. Not run in CI. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Metric grounding.** CSI tracks gain absolute scale and front/back disambiguation from an orthogonal modality. A single range collapses the ambiguity that ADR-029's geometry bounds show a near-colinear array cannot resolve from CSI alone. +- **Deterministic crossing resolution.** Track-swap identity errors at crossings are broken by range + AETHER re-ID, where re-ID alone was unreliable for similar body shapes. +- **Reuses, does not rebuild.** The HAL reuses the ADR-018 UDP transport, the `0xC511xxxx` magic family, the C6 802.15.4 timesync clock, the `pose_tracker.rs` cost-blend pattern, and the `mat/fusion.rs` `PositionFuser` ranking. The only genuinely new math is one EKF measurement update. +- **Activates dead code.** `EstimateSource::TimeOfArrival` finally has a producer; `simulate_rssi_measurements()`'s empty-handed path gains a real metric alternative for the MAT use case. +- **WorldGraph becomes metric.** ADR-139's anchor and track nodes get a real, version-tracked metric edge, so the digital twin can be corrected against physical ground truth rather than drifting. + +### 3.2 Negative + +- **New radio and hardware cost.** UWB is a second radio; even the cheapest form factor adds ~$15–25 per anchor and an anchor survey step. Sensing works without it (UWB is additive), but the metric benefit requires the hardware. +- **Anchor survey ceremony.** Like the ADR-135 baseline, anchors must be measured and registered before fusion is meaningful; a mis-surveyed anchor biases every range fused against it. +- **EKF linearization error.** The spherical update linearizes `h(x) = ‖x−a‖`; for a track very close to an anchor (small `‖c−a‖`), the Jacobian is ill-conditioned. Mitigated by a minimum-range guard and gating, but it is a real limit not present in the linear CSI update. +- **New struct surface.** `PoseTrack` grows a `ConstraintTrackState`, `TrackerConfig` grows four fields, and `WorldGraph` grows anchor/edge methods. All are additive and default-inert, but they widen the public API. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| NLOS range biases a track long without being flagged | Medium (through-wall ranging) | Track pulled away from truth | Quality-derived `uncertainty_m` inflation + 3-sigma gate; persistent outliers logged, not applied | +| Wrong-track association at a crossing | Low–Medium | Identity swap with high confidence | Spherical Mahalanobis gate + AETHER re-ID; `AmbiguousResolved.margin` surfaced; privacy modes that forbid identity binding fall back to anonymous spherical constraint only | +| Mis-surveyed anchor | Medium (manual measurement) | Systematic bias on every fused range from that anchor | `anchor_survey_version` invalidation; optional auto-learn *proposal* for operator confirmation; never silent self-update | +| EKF divergence for a track adjacent to an anchor | Low | Gain blow-up, track teleport | Minimum-range guard on `‖c−a‖`; gate rejects the resulting large innovation | +| UWB frames starve the aggregator demux of CSI | Low | Dropped CSI frames | UWB ranges are ~10 Hz per tag vs CSI 20 Hz; demux is a cheap magic-match `else if` arm, same as the seven existing `RUVIEW_*` arms | + +--- + +## 4. Alternatives Considered + +### 4.1 Why Not a Full Factor Graph (GTSAM-style) + +A factor graph would jointly optimize all keypoints, all ranges, and all anchors in one nonlinear least-squares batch — theoretically optimal. Rejected for this codebase because: (a) it would *replace* the existing real-time `pose_tracker.rs` EKF rather than extend it, discarding a tested, shipping tracker; (b) batch optimization is not naturally online and would complicate the 20 Hz real-time loop; (c) it pulls in a heavy nonlinear-solver dependency where the existing tracker uses only hand-rolled diagonal Kalman math. The incremental EKF range update captures ~all the benefit (range tightens the prior) at a fraction of the integration cost, and the *auto-learn anchor* path in §2.7 can use an offline batch solver where the batch formulation genuinely helps. + +### 4.2 Why Not Pure Mahalanobis Gate-and-Penalty (No State Update) + +The simplest option: use the range only to *score* association (penalize tracks inconsistent with the range) but never let it move the state. Rejected because it throws away the metric correction — the whole point. A range that says "this person is 1.8 m from the anchor" should *move* a CSI estimate that says 2.3 m, not merely down-rank an assignment. We keep the gating (it is good for outlier rejection) but pair it with the EKF state update. + +### 4.3 Why Not Treat UWB as Just Another `PositionEstimate` Source in `mat/fusion.rs` + +We could skip `pose_tracker.rs` entirely and only fuse UWB at the MAT `PositionFuser` level (where `TimeOfArrival` already exists). Rejected as the *sole* path because the `PositionFuser` does a weighted-average of *independent* position estimates; deriving a position from a single range first requires a prior, and the best available prior is the CSI track state inside the tracker. Fusing at the tracker (§2.5) uses that prior correctly; fusing only at `mat` would need ≥3 simultaneous ranges to trilaterate a standalone position, which is a much stronger hardware requirement. We do **both**: tracker-level for single-range tightening, MAT-level for the multi-anchor trilateration use case. + +### 4.4 Why a New `0xC511xxxx` Magic Rather Than a New Transport + +UWB could ride its own port/protocol. Rejected to avoid a second aggregator, a second timesync, and a second firmware OTA channel. Extending the ADR-018 magic family (next id `0xC5110008`) means the existing `aggregator/` demux, the C6 802.15.4 clock, and the existing provisioning path all apply unchanged — the same reasoning that made the seven `RUVIEW_*_MAGIC` sibling packets share one port. + +--- + +## 5.

The threshold structs (`JointErrorThresholds`, `TrackingThresholds`, `VitalSignThresholds`) carry the `Default` impls that encode the deployment gates. + +2. **`wifi-densepose-train/src/eval.rs`** implements the ADR-027 MERIDIAN cross-environment evaluator — `CrossDomainEvaluator::evaluate()` returns `CrossDomainMetrics { in_domain_mpjpe, cross_domain_mpjpe, few_shot_mpjpe, cross_hardware_mpjpe, domain_gap_ratio, adaptation_speedup }`. Domain `0` is in-domain; non-zero domain IDs are cross-domain. It reports a single scalar `domain_gap_ratio = cross / in_domain`. + +These two surfaces share **no common driver**. There is: + +- **No feature-ablation concept anywhere.** A workspace-wide search for `ablation` / `Ablation` across `v2/crates` returns zero matches. There is no struct that says "run the acceptance test with CIR disabled" or "with Doppler enabled," and no way to attribute a tier change to a specific feature branch (CSI-only vs CSI+CIR vs +Doppler). +- **No privacy-leakage metric in the eval path.** Privacy is enforced *structurally* in `wifi-densepose-bfld` — `signature_hasher.rs` implements the ADR-120 BLAKE3-keyed per-site, daily-rotated `rf_signature_hash` (invariant I3), and `embedding.rs` keeps `IdentityEmbedding` in-RAM-only (invariant I1/I2). But there is no *measured* leakage scalar: nothing runs a membership-inference attack against the hash-rotation pipeline and reports a number in `[0, 1]`. The acceptance test cannot fail a model for leaking identity. +- **No latency profile in the acceptance result.** `RuViewAcceptanceResult` reports accuracy and tracking but carries no `p50`/`p95`/`p99` inference-latency fields. The ADR-031 mode says nothing about timing budgets (a grep of `ADR-031` for `latency`/`p95` returns nothing), so a model that passes Gold at 800 ms/frame is indistinguishable from one at 40 ms/frame. +- **No per-variant determinism binding.** The proof harness exists and is mature: `wifi-densepose-train/src/proof.rs` runs `N_PROOF_STEPS = 50` under `PROOF_SEED = 42` / `MODEL_SEED = 0` and SHA-256-hashes the model weights (`hash_model_weights()`), comparing against `expected_proof.sha256`. The signal side mirrors this — `src/bin/calibration_proof_runner.rs` (ADR-135) and `src/bin/cir_proof_runner.rs` (ADR-134) hash deterministic synthetic outputs against `archive/v1/data/proof/expected_calibration_features.sha256` and `expected_cir_features.sha256`. But **no proof artifact pins an ablation report**: there is no `expected_ablation_*.sha256`, so re-running the matrix on a fixed seed could silently produce a different tier and CI would not notice. + +The cost of the gap is concrete. When ADR-134 (CIR) and ADR-135 (calibration) landed, the only way to know whether CIR *helped* presence/localization was to read the commit message — there was no harness that ran the acceptance test with and without CIR and emitted a side-by-side delta. As ADR-144 (UWB fusion) and the BFLD privacy modes (ADR-141) come online, the number of feature combinations grows combinatorially, and "does turning on feature X regress tier or leak identity?" becomes unanswerable without a deterministic ablation matrix. + +### 1.2 What "Ablation" Means Here + +An **ablation** is one acceptance-test run over a fixed evaluation set with a named subset of signal features enabled. The matrix is the set of those runs plus the pairwise deltas between them. Each ablation produces: + +- A `RuViewAcceptanceResult` (the existing struct, unchanged) → tier, PCK, OKS, MOTA, breathing error. +- New scalar metrics this ADR adds: presence accuracy, localization error, activity accuracy, FP/FN rates, latency p50/p95/p99, **privacy-leakage score** ∈ `[0, 1]`, and cross-room degradation. +- A determinism record: the SHA-256 of the variant's witness-replay output, which must match the per-variant expected hash or CI fails. + +An ablation is **not** a hyperparameter sweep or a training run. It evaluates a *fixed, already-trained* `model.bin` snapshot under different *inference-time feature gates*. Training is out of scope — this ADR consumes the model the way `proof.rs` consumes a fixed-seed model. + +### 1.3 Hardware Constraints on the Feature Set + +The ablation feature combinations are bounded by what RuView hardware can actually produce, per the project hardware table and ADR-136's streaming engine: + +| Tier | Feature | Source | Available today? | +|------|---------|--------|------------------| +| F0 | CSI amplitude/phase | ESP32-S3 (20 MHz, 52 active subcarriers, HT20) | Yes (COM9) | +| F1 | CIR (delay taps) | ADR-134 `CirEstimator` over the same CSI | Yes | +| F2 | Doppler / micro-motion | ADR-014 spectrogram over a frame window | Yes | +| F3 | BFLD beamforming-feedback features | ADR-118/120 `wifi-densepose-bfld` (802.11ac/ax BFI) | Yes (gated) | +| F4 | UWB range constraint | ADR-144 fusion with WorldGraph anchors | **No — hardware not landed** | + +The 6-node TDM mesh and the 20 MHz ESP32-S3 bandwidth cap the realistic combinations. UWB (F4) is **deferred**: ADR-144 specifies the fusion contract but the ranging hardware is not in the fleet, so the `+UWB` ablation is a *defined-but-skipped* variant (it appears in the matrix as `Skipped { reason }`, not silently absent — same pattern as the unprovisioned seeds in ADR-135 §2.8). + +### 1.4 Pipeline Position + +``` +model.bin snapshot (fixed) + + witness-bundle CSI replay (PROOF_SEED=42, fixed salt) + │ + ▼ + AblationHarness::run_matrix() ← NEW (wifi-densepose-train) + │ for each AblationVariant (F-mask): + │ feature-gate the signal stages (ADR-136 streaming engine) + │ → eval.rs CrossDomainEvaluator (cross-room degradation) + │ → ruview_metrics.rs acceptance (tier, PCK/OKS/MOTA/vitals) + │ → SpecMetrics (presence/loc/activity/FP-FN) + │ → LatencyProfile (criterion p50/p95/p99) + │ → PrivacyLeakage (MIA on ADR-120 hash-rotation pipeline) + │ → SHA-256(variant canonical bytes) vs expected_ablation_*.sha256 + ▼ + AblationReport → markdown auto-report + summary.json +``` + +The harness sits *above* the streaming engine: it does not re-derive features, it toggles which ADR-136 stages are active and re-reads the existing `eval.rs` / `ruview_metrics.rs` outputs. Determinism is inherited from the proof harness substrate (ADR-011). + +--- + +## 2. Decision + +### 2.1 The Six Ablation Variants + +We define exactly six feature combinations, of which five run today and one is deferred: + +```rust +// New module: wifi-densepose-train/src/ablation.rs + +/// One feature combination to evaluate. Bitflags over the signal stages +/// that ADR-136's streaming engine can gate on or off. +#[derive(Debug, Clone, Copy, PartialEq, Eq)] +pub enum AblationVariant { + /// F0 only: raw CSI amplitude + phase.

It is a pure descriptor. The harness translates each variant into a `StageMask` consumed by the ADR-136 streaming engine; the streaming engine remains the single owner of feature extraction. This keeps the train crate free of any `unsafe`/FFI signal code (consistent with `lib.rs`'s note that only `tch` brings `unsafe`). + +The order in `MATRIX` is **load-bearing**: it is the iteration order used by the proof hash and by the report, so it must never be re-sorted (same discipline as `proof.rs::hash_model_weights()` sorting variables by name for stable order). + +### 2.2 Spec Metrics Bound to Existing Interfaces + +The new metrics are added as additive structs that *compose with*, not replace, `RuViewAcceptanceResult` and `CrossDomainMetrics`. We deliberately do not widen the existing public structs (they are consumed by checked-in tests and by the `summary()` formatters), per the rule "prefer editing an existing file but do not break a stable public API." + +```rust +/// Detection-mode spec metrics that the ADR-031 acceptance test does not +/// currently capture. Every field traces to a documented evaluation protocol. +#[derive(Debug, Clone)] +pub struct SpecMetrics { + /// Presence detection accuracy (TP+TN)/N over the labelled set. + pub presence_accuracy: f32, + /// Localization error in metres (mean Euclidean, occupied frames only). + pub localization_err_m: f32, + /// Activity classification accuracy (multi-class, balanced). + pub activity_accuracy: f32, + /// Breathing-rate error in BPM (mirrors VitalSignResult.breathing_error_bpm). + pub breathing_err_bpm: f32, + /// False-positive rate: P(predict occupied | truly empty). + pub false_positive_rate: f32, + /// False-negative rate: P(predict empty | truly occupied). + pub false_negative_rate: f32, +} + +/// Inference-latency profile measured with `criterion`-style sampling over +/// the replay set.

We measure it as a **membership-inference (MIA) attack success above chance**, normalized to `[0, 1]`. + +**Setup.** The ADR-120 pipeline maps identity features → `rf_signature_hash = BLAKE3-keyed(site_salt, day_epoch || features)` (`signature_hasher.rs`). The structural guarantee (invariant I3) is that two sites, or two days, produce uncorrelated hashes. The *measured* question is different: given the model's emitted per-frame outputs for a known set of enrolled identities (members) and an equal set of held-out identities (non-members), can a simple attacker classifier decide membership better than a coin flip? + +```rust +/// Privacy-leakage measurement against the ADR-120 hash-rotation pipeline. +#[derive(Debug, Clone)] +pub struct PrivacyLeakage { + /// MIA attacker AUC ∈ [0.5, 1.0]; 0.5 = no leakage, 1.0 = full recovery. + pub mia_auc: f32, + /// Normalized leakage score ∈ [0,1]: 2*(mia_auc − 0.5), clamped. + pub leakage_score: f32, + /// Fisher-information trace of identity-feature gradients (diagnostic). + /// Higher trace = identity is more recoverable from model sensitivity. + pub fisher_trace: f32, + /// Number of (member, non-member) pairs probed. + pub n_probes: usize, +} +``` + +Two estimators are reported; the harness uses the MIA estimator for the pass/fail gate and the Fisher trace as a diagnostic: + +1. **MIA simulator** (gate). Train a lightweight shadow classifier on the variant's emitted outputs to predict member/non-member, evaluate its AUC on a disjoint split. `leakage_score = clamp(2·(AUC − 0.5), 0, 1)`. An AUC of 0.5 → `leakage_score = 0` (the model leaks nothing the hash rotation has not already destroyed); AUC of 1.0 → `leakage_score = 1.0`. +2. **Fisher-information trace** (diagnostic). The trace of the Fisher information matrix of the model's outputs with respect to the (pre-hash) identity features. This is a closed-form sensitivity measure: a model whose outputs are invariant to identity features has near-zero trace. It is reported but not gated, because its scale is not normalized across variants. + +**Why MIA and not just trusting the structural invariant.** The BLAKE3 hash rotation guarantees that the *stored signature* cannot be cross-correlated. It says nothing about whether the *pose/presence outputs themselves* carry a usable identity fingerprint (gait, body geometry). A model can pass every ADR-120 structural test and still leak identity through its keypoint trajectories. MIA measures exactly that residual channel. The pass gate is `leakage_score ≤ 0.05`, i.e. attacker AUC ≤ 0.525 — within sampling noise of chance for the probe count used. + +**Determinism.** The shadow classifier is trained with a fixed seed derived from `PROOF_SEED = 42` and a fixed split, so the AUC is reproducible. The Fisher trace is computed on the fixed replay set. Both feed the per-variant proof hash (§2.6) at coarse quantization, following the cross-platform lesson documented in `calibration_proof_runner.rs` (lines 1–13): quantize to 1e-3 in natural order, no sort, no libm-sensitive comparison. + +### 2.4 `ruview-cli --ablation mode=auto` + +A new CLI surface drives the matrix. It is added as a `Commands::Ablation(AblationArgs)` variant alongside the existing `Commands::Calibrate` / `Commands::Mat` / `Commands::Version` in `wifi-densepose-cli/src/lib.rs` (the same `clap` `Subcommand` enum that already hosts `Calibrate(calibrate::CalibrateArgs)`). + +``` +wifi-densepose ablation [OPTIONS] + +OPTIONS: + --mode auto | single [default: auto] + auto: run the full 6-variant matrix. + single: run one --variant. + --variant csi_only | cir_only | csi_plus_cir | + plus_doppler | plus_bfld | plus_uwb + (required when --mode=single) + --model Path to the frozen model.bin snapshot to evaluate. + --replay Witness-bundle CSI replay file + [default: archive/v1/data/proof/sample_csi_data.json] + --seed Proof seed [default: 42] + --salt Fixed 32-byte site salt for the BLAKE3 hasher + (deterministic privacy probe).

Snapshot the model: load `--model`, freeze weights, record `SHA-256(model.bin)` as the model-version stamp. +2. For each `AblationVariant::MATRIX` entry where `is_runnable()`: + a. Set the streaming `StageMask`; replay the CSI under `PROOF_SEED=42` + fixed salt. + b. Compute `RuViewAcceptanceResult`, `SpecMetrics`, `LatencyProfile`, `PrivacyLeakage`, `CrossRoomDegradation`. + c. Serialise the variant's canonical metric bytes (coarse-quantized, natural order) and SHA-256 it. Compare to `expected_ablation_.sha256`; fail CI on mismatch in `--check-hash` mode. +3. For `PlusUwb`: emit `VariantOutcome::Skipped { reason: "ADR-144 UWB hardware not present" }`. +4. Emit the markdown report and `summary.json`. + +The exit-code convention matches `proof.rs`: `0 = PASS`, `1 = FAIL` (hash mismatch or threshold breach), `2 = SKIP` (no expected hash file). This lets the ablation step drop into the existing ADR-011 / ADR-028 witness chain without a new CI grammar. + +**Why `criterion` for latency.** The `criterion` crate gives a sampled distribution with percentile extraction rather than a single timing. We run a fixed warmup + sample budget so p50/p95/p99 are stable; the percentiles are quantized to 0.1 ms before hashing so wall-clock jitter does not break the proof hash (the metric is gated on `p95 ≤ threshold`, the *hash* only pins the quantized accuracy/privacy fields, not raw latency — latency is environment-dependent and therefore reported but excluded from the determinism hash, exactly as runtime wall-clock is excluded from `proof.rs`'s weight hash). + +### 2.5 Cross-Room Degradation (MERIDIAN Extension) + +ADR-027's `CrossDomainEvaluator` already partitions predictions by domain ID and computes `domain_gap_ratio`. This ADR extends the *reporting*, not the evaluator: it consumes the existing `evaluate()` output and adds room_A − room_B deltas plus a per-joint heatmap. + +```rust +/// Extend eval.rs reporting with a two-room A/B split and a per-joint heatmap. +/// `room_a_preds`/`room_b_preds` are (pred, gt) pairs as in CrossDomainEvaluator. +pub fn cross_room_degradation( + evaluator: &crate::eval::CrossDomainEvaluator, + room_a: &[(Vec, Vec)], + room_b: &[(Vec, Vec)], +) -> CrossRoomDegradation; +``` + +The per-joint heatmap is the 17-entry vector of `PCK_room_A[j] − PCK_room_B[j]`, indexed by COCO joint (the same 17-joint convention used in `ruview_metrics.rs::COCO_SIGMAS` and `metrics.rs::COCO_KP_SIGMAS`). The multi-room test set reuses the domain-label convention: room A is domain `0` (in-domain), room B is a non-zero domain ID. This is a pure consumer of `eval.rs` — no change to `CrossDomainEvaluator` or `CrossDomainMetrics`. + +### 2.6 Determinism Binding to the Proof Harness + +Each runnable variant produces a canonical byte payload hashed with SHA-256, following the established signal-proof pattern (`calibration_proof_runner.rs`, `cir_proof_runner.rs`). A new binary `src/bin/ablation_proof_runner.rs` in `wifi-densepose-signal` (alongside the two existing `*_proof_runner.rs`) regenerates the matrix on the fixed seed/salt/replay and asserts the hashes match `archive/v1/data/proof/expected_ablation_.sha256`. + +**Canonical payload per variant** (coarse quantization, natural field order, no sort — the libm-portability rule from `calibration_proof_runner.rs` lines 1–13): + +``` +[0] variant slug bytes (length-prefixed, like proof.rs param names) +[1] model.bin SHA-256 (32 bytes) ← model version +[2] calibration version tag (from ADR-135 baseline meta) +[3] privacy decision tag (BFLD mode, ADR-141) +[4] pck_all (× 1e3 round) u16 +[5] oks (× 1e3 round) u16 +[6] mota (× 1e3 round) u16 +[7] presence_acc (× 1e3 round) u16 +[8] localization (× 1e3 round, metres) u16 +[9] activity_acc (× 1e3 round) u16 +[10] fp_rate (× 1e3 round) u16 +[11] fn_rate (× 1e3 round) u16 +[12] leakage_score (× 1e3 round) u16 +[13] tier byte (0=Fail,1=Bronze,2=Silver,3=Gold) +``` + +Latency fields are **excluded** from the hash (wall-clock is non-deterministic across machines, exactly as `proof.rs` excludes timing). Fields `[1]`–`[3]` make the evidence-traceability rule structural: the proof hash *cannot match* unless the model version, calibration version, and privacy decision are the ones that were pinned — so every reported semantic metric traces to a specific model + calibration + privacy decision, by construction. + +### 2.7 Evidence Traceability + +Per the project rule that every semantic state record traces to signal evidence + model version + calibration version + privacy decision, the `AblationReport` carries these four provenance fields per variant and binds them into the proof hash (§2.6 fields `[1]`–`[3]`, plus the replay file SHA as signal evidence): + +```rust +#[derive(Debug, Clone)] +pub struct VariantProvenance { + /// Signal evidence: SHA-256 of the witness-replay CSI file. + pub replay_sha256: String, + /// Model version: SHA-256 of the frozen model.bin. + pub model_sha256: String, + /// Calibration version: ADR-135 baseline schema_version + captured_at. + pub calibration_version: String, + /// Privacy decision: the BFLD mode (ADR-141) under which features were gated. + pub privacy_mode: String, +} +``` + +A variant whose provenance cannot be fully populated (e.g. no calibration baseline loaded) is reported as `Degraded`, never as a passing tier — the report refuses to claim a Gold tier without a calibration version, the same way ADR-135 refuses `subtract()` on a tier mismatch. + +### 2.8 Output: Auto-Report and Summary JSON + +The markdown report has one row per variant, columns: variant slug · tier · PCK · OKS · MOTA · presence · localization · activity · FP · FN · **leakage** · p50/p95/p99 ms · runnable?. A delta block lists pairwise deltas of interest (e.g. `csi_plus_cir − csi_only` to show CIR's contribution; `plus_bfld − csi_plus_cir` to show whether BFLD features regress privacy). `summary.json` carries the same data machine-readably plus per-variant `VariantProvenance`, for the cognitum-v0 dashboard and the ADR-141 privacy control plane to ingest. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **Feature contribution becomes measurable.** The `csi_plus_cir − csi_only` delta answers "did CIR (ADR-134) help?" with a number, not a commit message. Every future signal ADR can be justified or rejected against the matrix. +- **Privacy regression becomes a CI gate.** A model that leaks identity through pose trajectories — invisible to the structural ADR-120 tests — now fails `leakage_score ≤ 0.05`. This closes the residual-channel gap between *hash* privacy and *output* privacy. +- **Latency budget is enforced.** `p95 ≤ 100 ms` makes the ADR-136 real-time claim falsifiable. A Gold-accuracy model that misses the streaming budget no longer passes silently. +- **Deterministic and CI-friendly.** Reusing `PROOF_SEED=42` + fixed salt + witness replay + per-variant SHA-256 plugs directly into the ADR-011/ADR-028 witness chain. No new CI grammar; same `0/1/2` exit codes as `proof.rs`. +- **Additive, non-breaking.** `RuViewAcceptanceResult`, `CrossDomainMetrics`, and the threshold `Default` impls are untouched. The harness composes them; existing tests keep passing. +- **UWB is forward-declared.** `PlusUwb` is in the matrix as `Skipped`, so when ADR-144 hardware lands the only change is flipping `is_runnable()` and generating its expected hash. + +### 3.2 Negative + +- **Evaluation set must be curated.** The matrix is only as meaningful as the labelled multi-room replay set. Building a paired room_A/room_B set with presence/localization/activity labels is real work and is a prerequisite, not delivered by this ADR. +- **MIA is an estimate, not a proof.** A `leakage_score = 0` means *this* attacker found nothing; a stronger attacker might. The metric is a regression tripwire, not a cryptographic guarantee — the cryptographic guarantee remains ADR-120's structural invariant. +- **Six variants × full metric suite is slow.** The matrix runs the acceptance test, MERIDIAN eval, MIA shadow-classifier training, and criterion latency sampling per variant. This is a minutes-scale CI job, not seconds — it belongs in a nightly/witness job, not the per-commit fast path. +- **Latency excluded from the hash means latency can drift unnoticed.** We gate on `p95 ≤ threshold` but cannot pin it deterministically; a slow regression below the threshold is invisible. Mitigated by trending p95 in `summary.json` over time. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| MIA shadow classifier under-trained → false "no leakage" | Medium | A leaky model passes the privacy gate | Fix shadow-classifier capacity and probe count; report `n_probes`; require AUC CI confidence in `summary.json`; treat the gate as a tripwire, keep ADR-120 structural tests as the primary guarantee | +| Per-variant hash too sensitive → flaky CI across libm | Medium | Spurious FAIL on macOS vs Linux | Coarse u16 quantization at 1e-3, natural order, no sort — exactly the documented fix in `calibration_proof_runner.rs` lines 1–13; latency excluded from hash | +| Curated multi-room set leaks into training | Low | Inflated cross-room numbers | Evaluation replay set is frozen and SHA-pinned as `replay_sha256`; never used by `trainer.rs` | +| `PlusBfld` privacy probe needs a real `site_salt` | Low | Non-deterministic privacy hash | `--salt` defaults to a fixed test salt; the proof runner always uses the fixed salt so the hash is reproducible | +| Streaming `StageMask` toggles interact (e.g. CIR depends on calibration) | Medium | A variant silently runs uncalibrated | `VariantProvenance` requires a `calibration_version`; missing → `Degraded`, never a passing tier (§2.7) | + +--- + +## 4. Alternatives Considered + +### 4.1 Widen `RuViewAcceptanceResult` Instead of Adding Sibling Structs + +Rejected. `RuViewAcceptanceResult` and its `summary()` are consumed by checked-in tests in `ruview_metrics.rs` (e.g. `tier_determination_gold`) and likely by downstream callers. Adding `presence_accuracy`, `leakage_score`, etc. as fields would churn those tests and the `summary()` format string. The additive `SpecMetrics` / `LatencyProfile` / `PrivacyLeakage` siblings compose cleanly and leave the ADR-031 contract intact. + +### 4.2 A Hyperparameter Sweep Framework Instead of a Fixed Matrix + +Rejected. A general sweep (Optuna-style) optimizes *training*; this ADR evaluates a *frozen* model under inference-time feature gates. Conflating them would couple the harness to `trainer.rs` and break the proof-determinism story (a sweep is, by design, exploratory and non-deterministic). The fixed six-variant matrix is the minimum that answers "what does each feature contribute?" deterministically. + +### 4.3 Differential Privacy Accounting Instead of MIA + +Rejected for this scope. DP (ε-accounting) is a *training-time* mechanism; it would require instrumenting the training loop with noise and a privacy ledger. The deployed model is already trained, and the question here is empirical output leakage on a fixed snapshot — MIA answers that directly with no training-time change. DP remains a valid future ADR for the training pipeline, but it does not measure residual leakage of an already-shipped model. + +### 4.4 Skip Latency Entirely (Accuracy-Only Ablation) + +Rejected. ADR-136 makes a real-time streaming claim with no enforcement. Without a `p95` gate, a feature that doubles accuracy but triples latency would "win" the ablation and ship, breaking the 20 Hz budget. Latency is reported and gated even though it is excluded from the determinism hash. + +### 4.5 Define `+UWB` as Absent Rather Than `Skipped` + +Rejected. Silently omitting `PlusUwb` until hardware lands would mean the matrix shape changes when hardware arrives, breaking report diffs and the per-variant hash set. The `Skipped { reason }` outcome keeps the matrix shape stable and self-documenting — the same discipline ADR-135 §2.8 uses for unprovisioned seed nodes. + +--- + +## 5. Testing and Acceptance + +### 5.1 Acceptance Criteria + +| ID | Criterion | Evidence | +|----|-----------|----------| +| AC1 | `AblationVariant::MATRIX` has exactly 6 entries in canonical order; `PlusUwb.is_runnable() == false`, all others `true`. | `ablation::tests::matrix_shape` | +| AC2 | `cross_room_degradation()` returns a 17-entry `per_joint_pck_delta` and a signed `accuracy_delta`; perfect-equal rooms → all-zero heatmap and `accuracy_delta == 0`. | `ablation::tests::cross_room_zero_when_identical` | +| AC3 | `PrivacyLeakage` on an identity-invariant model → `leakage_score < 0.05` (AUC ≈ 0.5); on an identity-encoding model → `leakage_score > 0.5`. | `ablation::tests::mia_separates_leaky_model` | +| AC4 | `SpecThresholds::default()` gates: `presence ≥ 0.90`, `loc ≤ 0.50 m`, `activity ≥ 0.70`, `FP ≤ 0.05`, `FN ≤ 0.10`, `p95 ≤ 100 ms`, `leakage ≤ 0.05`. | `ablation::tests::spec_thresholds_default` | +| AC5 | A variant with missing `calibration_version` is reported `Degraded`, never a passing tier. | `ablation::tests::no_calibration_is_degraded` | +| AC6 | Re-running the matrix under `PROOF_SEED=42` + fixed salt + fixed replay produces byte-identical canonical payloads (per-variant hash stable across two runs). | `ablation::tests::canonical_bytes_deterministic` | +| AC7 | `ablation_proof_runner` exits `0` when all runnable variants match `expected_ablation_.sha256`, `1` on any mismatch, `2` on placeholder hashes. | `cargo run -p wifi-densepose-signal --bin ablation_proof_runner --release --no-default-features` | +| AC8 | The proof hash changes if the model SHA, calibration version, or privacy mode changes (provenance is bound into the hash). | `ablation::tests::provenance_affects_hash` | + +### 5.2 Test Tiers + +**Tier 1 — Matrix and metric unit tests (CI).** `matrix_shape`, `spec_thresholds_default`, `cross_room_zero_when_identical`, and the MIA separation test with two synthetic models (one identity-invariant, one that copies an identity feature into its output).

Context + +### 1.1 The Gap + +The current Rust stack already owns a shared RF encoder backbone and one contrastive projection head, but it lacks the multi-head fan-out, the per-head uncertainty, and the formalized batcher that ADR-140's `SemanticStateRecord` and ADR-136's `QualityScored` trait will require as upstream producers. Three concrete observations from the real codebase establish the gap. + +**A single backbone exists, but it feeds only two task heads.** `v2/crates/wifi-densepose-train/src/model.rs` defines `WiFiDensePoseModel` with a shared `translator` → `backbone` path producing `ModelOutput.features`, consumed by exactly two heads: + +```rust +// v2/crates/wifi-densepose-train/src/model.rs +pub struct WiFiDensePoseModel { + // translator → backbone (shared) ... + kp_head: KeypointHead, // line 70 + dp_head: DensePoseHead, // line 71 +} +``` + +`forward_impl()` (model.rs ~line 193) emits `ModelOutput { keypoints, part_logits, uv_coords, features }`. The `features` tensor is the shared representation, but it is consumed only by pose-regression heads. There is no presence head, count head, activity head, vitals head, gait head, or an exported identity-embedding head wired off the same backbone. Presence, count, activity, vitals, and gait are computed today by *separate* signal-processing modules (`ruvsense/`, `wifi-densepose-vitals`) that do not share the encoder representation, so they cannot benefit from contrastive pretraining (ADR-024) or cross-environment LoRA (ADR-027). + +**A projection head and contrastive loss exist, but in the serving crate, not as a formal head taxonomy.** `v2/crates/wifi-densepose-sensing-server/src/embedding.rs` already implements: +- `ProjectionHead` (2-layer MLP, `d_model=64 → d_proj=128`, ReLU + L2-norm), with optional rank-4 LoRA adapters (`lora_1`, `lora_2`) for environment-specific fine-tuning (ADR-027) — all pure-Rust `Vec` (`forward(&self, x: &[f32]) -> Vec`, embedding.rs line 131). +- `info_nce_loss()` (embedding.rs line 476) and `CsiAugmenter::augment_pair()` (line 362). +- `EmbeddingExtractor`, the full backbone + projection pipeline. + +This is the *seventh* head (identity-embedding) of the proposed taxonomy, already materialized — but as a one-off in the serving crate rather than as one branch among seven over a shared encoder. It is the proof that the pure-Rust `f32` ABI is viable; it is not yet a general multi-task head abstraction. + +**Contrastive pair construction exists, but ad hoc.** `v2/crates/wifi-densepose-train/src/rapid_adapt.rs` (MERIDIAN Phase 5) defines `AdaptationLoss::ContrastiveTTT` whose doc-comment is literally *"positive = temporally adjacent, negative = random"* (rapid_adapt.rs line 9), and `contrastive_step()` (line 201) implements it. But this lives inside test-time adaptation, sampling within a single CSI stream. There is **no `ContrastiveBatcher`** anywhere in the workspace (`grep -rn "ContrastiveBatcher" v2/crates` returns nothing). The cross-environment positive/negative pair construction that ADR-027 §6.x requires — same activity / same person across *different rooms* as positives, different semantics as negatives — has no formal sampling contract. Batched iteration is provided generically by `DataLoader`/`DataLoaderIter` over `CsiSample` (`dataset.rs` line 150), with no notion of anchor/positive/negative tuples. + +**Consequence.** ADR-140's `SemanticStateRecord` is meant to carry a `model_version` and trace every semantic field to its evidence. ADR-136's `QualityScored` trait is meant to attach confidence bounds to every stage output. Today, the only encoder-derived quantity that could populate such a record is pose; presence/count/activity/vitals/gait arrive from non-encoder modules with their own (incomparable) confidence conventions, and none of them emit calibrated uncertainty. This ADR closes that gap: a single shared RF encoder with seven typed heads, each emitting a `QualityScored` output with per-head uncertainty, trained with a formalized `ContrastiveBatcher` and a calibration-robustness loss that ties the encoder to ADR-135's `calibration_id`. + +### 1.2 Scope Boundary + +This ADR is about **the encoder and its head fan-out**, not about the downstream semantic record (ADR-140) or the streaming frame contracts (ADR-136). It defines: +- The seven-head taxonomy over the shared backbone in `wifi-densepose-nn`. +- The per-head uncertainty quantification layer and its mapping onto `QualityScored`. +- The calibration-robustness loss tying training to `calibration_id`. +- The `ContrastiveBatcher` sampling contract in `wifi-densepose-train`. +- The pure-Rust `f32` tensor ABI for deterministic, witnessable inference. +- The ablation hooks consumed by ADR-145. + +It does **not** define the `SemanticStateRecord` wire schema (ADR-140) nor the stage abstraction (ADR-136); it defines the *producer* that feeds them. + +### 1.3 Why `wifi-densepose-nn` and Not `wifi-densepose-train` + +Training lives in `wifi-densepose-train` (libtorch / `tch`), which is GPU- and `Tensor`-bound. Inference must run on the Pi+Hailo cluster and in WASM. The current encoder *definition* lives in `wifi-densepose-train/src/model.rs` (a libtorch graph), while the *inference* projection head lives in `wifi-densepose-sensing-server/src/embedding.rs` (pure Rust `f32`). This split is the underlying disease: the head taxonomy and the ABI belong in `wifi-densepose-nn` (which already owns `Tensor` = `Array{1..4}D` in `tensor.rs`, and `densepose.rs`/`inference.rs`), so both the training crate and the serving crate depend on one definition. The new head-trait and uncertainty types are added to `wifi-densepose-nn`; `wifi-densepose-train` adds only the `ContrastiveBatcher` and the loss terms. + +### 1.4 Pipeline Position + +``` + CSI window (amplitude, phase) + → [wifi-densepose-signal preprocessing + ADR-135 baseline subtract] + → RfEncoder::encode() (shared backbone → embedding z ∈ R^d_model) [wifi-densepose-nn, NEW trait] + ├── PoseHead ─┐ + ├── PresenceHead │ + ├── CountHead │ each head: forward → (value, UncertaintyHead → bounds) + ├── ActivityHead ├─ → MultiTaskOutput { per-head QualityScored } [NEW] + ├── VitalsHead │ + ├── GaitHead │ + └── IdentityEmbedHead ─┘ (the existing ADR-024 ProjectionHead, relocated) + → SemanticStateRecord assembly (ADR-140; stamps model_version + calibration_id) + → Fusion engine quality scoring (ADR-136 QualityScored) +``` + +During training, the shared backbone receives gradients from all *enabled* heads (ADR-145 ablation matrix can disable any head), plus the contrastive term over `ContrastiveBatcher` tuples, plus the calibration-robustness term over `calibration_id` groups. + +--- + +## 2.

Heads #2, #4, #5, #6 supersede the standalone signal modules *as encoder-derived alternatives*; the signal modules remain for the no-model fallback path and as ablation baselines (ADR-145). + +```rust +// v2/crates/wifi-densepose-nn/src/encoder/mod.rs (NEW module) +use crate::tensor::Tensor; // Array{1..4}D — pure Rust, no libtorch at inference + +/// Shared RF encoder backbone.

The learned-σ head is two extra linear layers per regression head and adds a Gaussian-NLL term to the loss; the categorical heads need no extra parameters (the softmax *is* the posterior). This keeps the pure-Rust `f32` inference path single-pass and deterministic. + +**Calibration of the score itself.** `confidence` must be *calibrated* (a 0.8 confidence is right 80% of the time), enforced via post-hoc temperature scaling per head, with Expected Calibration Error (ECE) checked in the acceptance tests (§2.6). The temperature scalars are stored alongside weights and stamped into `model_version`. + +### 2.3 Calibration-Robustness Loss Tied to ADR-135 `calibration_id` + +The encoder must be **invariant to per-device baseline shifts** so that an embedding for "empty room, device A" and "empty room, device B" land in the same place and a person produces the same activity/pose regardless of which calibrated node observed them. ADR-135 produces a `BaselineCalibration` per device with a stable identity; this ADR introduces `CalibrationId` as a hashable key over `(device_id, tier, captured_at)` and uses it as a **domain label** in a calibration-robustness loss. + +``` +L_total = Σ_h w_h · L_head_h(enabled) + + λ_con · L_contrastive (NT-Xent over ContrastiveBatcher tuples, §2.4) + + λ_cal · L_calib_robust (NEW, this section) + + λ_uq · L_uncertainty (Gaussian-NLL terms across regression heads) +``` + +`L_calib_robust` is a **calibration-adversarial / variance-penalty** term. Two equivalent formulations are supported (config-selectable): + +1. **Group-variance penalty (default).** For a mini-batch, group embeddings by `calibration_id`. Penalize the *between-group* variance of the embedding conditioned on the *same* semantic label (same activity/presence), pulling cross-device representations of the same event together: + `L_calib_robust = mean_over_labels( Var_{calib_id}( z | label ) )`. +2. **Gradient-reversal domain classifier (DANN-style).** A small `calibration_id` classifier behind a gradient-reversal layer; the encoder learns features the classifier *cannot* use to recover which calibrated device produced them. + +The default is the group-variance penalty: it has no adversarial training instability, it requires `≥2` distinct `calibration_id`s per mini-batch (enforced by `ContrastiveBatcher`, §2.4), and it directly operationalizes "invariant to per-device baseline shift." When `calibration_id` is `None` (uncalibrated capture), the sample is excluded from `L_calib_robust` but still contributes to head losses. + +**Interface boundary.** The training loop reads `CalibrationId` from each `CsiSample` (a new optional field populated from the capture's ADR-135 baseline). Inference stamps the *active* `calibration_id` into `MultiTaskOutput` so the semantic record traces to the calibration version — satisfying the project provenance rule. + +### 2.4 The `ContrastiveBatcher` Sampling Contract + +Formalize the ad-hoc rapid_adapt pairing (`positive = temporally adjacent, negative = random`) into a first-class, cross-environment sampler in `wifi-densepose-train`. It produces **anchor / positive / negative** tuples obeying ADR-027's cross-environment generalization requirement. + +```rust +// v2/crates/wifi-densepose-train/src/dataset.rs (NEW; alongside DataLoader) +pub struct ContrastiveBatcher<'a> { + dataset: &'a dyn CsiDataset, + batch_size: usize, + strategy: PairStrategy, + /// Minimum distinct calibration_ids per batch (≥2 to make L_calib_robust well-posed). + min_calib_ids: usize, + seed: u64, +} + +pub enum PairStrategy { + /// ADR-024 default: positive = augmented view of same window (CsiAugmenter), + /// negative = other windows in the batch. + SelfSupervised, + /// ADR-027: positive = SAME semantic label in a DIFFERENT environment + /// (different calibration_id / room); negative = different label. + /// This is the contract that forces cross-environment invariance. + CrossEnvironment { label_key: LabelKey }, + /// rapid_adapt parity: positive = temporally adjacent, negative = random. + Temporal { window: usize }, +} + +pub struct ContrastiveBatch { + pub anchors: Vec, + pub positives: Vec, // aligned 1:1 with anchors + pub negatives: Vec>, // per-anchor negative set (in-batch or sampled) + pub calib_ids: Vec>, // aligned with anchors; ≥ min_calib_ids distinct +} + +impl<'a> ContrastiveBatcher<'a> { + pub fn new(dataset: &'a dyn CsiDataset, batch_size: usize, + strategy: PairStrategy, seed: u64) -> Self; + /// Deterministic given (seed, epoch). Reuses DataLoader's xorshift shuffle. + pub fn iter(&self, epoch: u64) -> impl Iterator + '_; +} +``` + +**Contract guarantees** (tested in §2.6): +1. **Determinism**: `(seed, epoch)` fully determines the batch sequence — same xorshift RNG already used by `DataLoader`. +2. **Positive validity**: under `CrossEnvironment`, `positive.label == anchor.label` AND `positive.calibration_id != anchor.calibration_id` (when ≥2 environments exist; otherwise it degrades gracefully to `SelfSupervised` with a warning). +3. **Negative validity**: every negative differs from the anchor in the semantic label dimension being contrasted. +4. **Calibration coverage**: each batch contains ≥ `min_calib_ids` distinct `calibration_id`s so `L_calib_robust` (§2.3) is computable; if the dataset has fewer, the batcher errors at construction (fail fast, not silent degradation). + +The existing `CsiAugmenter::augment_pair()` (embedding.rs line 362) provides the augmentation for `SelfSupervised`/`CrossEnvironment` positive views and is re-exported from `wifi-densepose-nn`. `info_nce_loss()` (embedding.rs line 476) consumes the batch unchanged. + +### 2.5 Pure-Rust `f32` Tensor ABI for Deterministic, Witnessable Inference + +**Decision: the inference ABI for the encoder and all heads is pure-Rust `f32` (`ndarray`), identical to the existing `wifi-densepose-nn::tensor::Tensor` enum (`Float1D..Float4D`, `tensor.rs`) and the `ProjectionHead::forward(&[f32]) -> Vec` convention already in `embedding.rs`.** No libtorch at inference time. + +Rationale: +- **Witnessability (ADR-028).** A pure-`f32` forward pass with a fixed evaluation order is bit-reproducible. The same SHA-256 proof discipline applied to ADR-134/135 (`verify.py` + `expected_features.sha256`) extends to the multi-task forward: feed a fixed CSI window, hash `MultiTaskOutput` floats, assert stable. libtorch reductions are not bit-stable across builds/devices and cannot anchor a witness hash. +- **Deployment.** Hailo/WASM targets do not link libtorch. The serving path (`embedding.rs`) already proves pure-Rust inference works; this generalizes it to all seven heads. +- **Training/inference split.** Training stays in `wifi-densepose-train` (libtorch `tch`). A weight-export step converts trained head/encoder weights into the flat `Vec` layout already used by `ProjectionHead::flatten_into`/`unflatten_from` (embedding.rs lines 159/165). Each head defines `flatten_into`/`unflatten_from` for round-trip stability (the same pattern as the existing projection head and its LoRA `flatten_lora`/`unflatten_lora`). + +**ABI specification (per head, little-endian f32, row-major):** +``` +[u32 magic 0x52464548 "RFEH"][u16 schema=1][u16 d_model][u8 n_heads][u8 head_mask] +[ModelVersion: 32-byte content hash of all weights] +[per enabled head: u16 head_id, u32 param_len, f32 × param_len] +``` +`ModelVersion` is the 32-byte hash that flows into `SemanticStateRecord.model_version` (ADR-140) — making the weights self-identifying so a record can never claim a model version it did not run. + +### 2.6 Ablation Hooks for ADR-145 + +Each head is individually toggleable at *both* train and inference time via `HeadMask`, exactly the toggle ADR-145's ablation matrix needs. + +```rust +pub struct HeadMask(u8); // bit per head; bit 0 = pose ... bit 6 = identity +impl HeadMask { + pub const ALL: HeadMask; + pub fn with(self, h: HeadKind) -> Self; + pub fn without(self, h: HeadKind) -> Self; + pub fn is_enabled(&self, h: HeadKind) -> bool; +} +``` + +- **Inference**: a disabled head is not evaluated and its `MultiTaskOutput` field is `None` (zero CPU cost — this is what ADR-145 measures for latency-vs-head-count). +- **Training**: a disabled head contributes no loss term and no gradient (its `w_h = 0`), so the ablation harness can measure each head's *contribution to the shared backbone* and detect negative transfer between heads. +- **Privacy-leakage probe (ADR-145)**: the `IdentityEmbedHead` and `GaitHead` can be disabled to produce a privacy-reduced model; the harness measures how much identity information remains recoverable from the *remaining* heads' embedding `z`. The encoder exposes `z` directly so ADR-145 can run a linear-probe leakage test without re-running heads. + +`MultiTaskRfModel::with_mask(mask)` returns a view enabling exactly the named heads; the ablation harness iterates the `2^7` (or a curated subset of) masks. + +### 2.7 Proof / Witness + +Per ADR-028, add witness rows to `docs/WITNESS-LOG-028.md`: + +| Row | Capability | Evidence | Hash | +|-----|-----------|----------|------| +| W-39 | Multi-task forward determinism (pure-Rust f32, fixed window) | `cargo test -p wifi-densepose-nn encoder::tests::forward_determinism` | SHA-256 of `MultiTaskOutput` floats | +| W-40 | `ContrastiveBatcher` determinism + positive/negative validity | `cargo test -p wifi-densepose-train dataset::tests::contrastive_contract` | SHA-256 of batch index sequence | +| W-41 | Per-head ECE within bound after temperature scaling | `cargo test -p wifi-densepose-nn encoder::tests::ece_calibrated` | recorded ECE values | +| W-42 | Weight ABI round-trip (flatten → unflatten bit-identical) | `cargo test -p wifi-densepose-nn encoder::tests::abi_round_trip` | SHA-256 of serialized weights | + +`source-hashes.txt` gains `SHA-256(encoder/mod.rs)` and `SHA-256(dataset.rs ContrastiveBatcher region)`. + +--- + +## 3. Consequences + +### 3.1 Positive + +- **One representation, seven tasks.** Presence/count/activity/vitals/gait now benefit from ADR-024 contrastive pretraining and ADR-027 cross-environment LoRA, instead of each signal module learning in isolation. Multi-task co-regularization typically improves data efficiency for the weaker heads (count, gait) by sharing the backbone with the data-rich heads (pose, presence). +- **Comparable, calibrated confidences.** Every head emits `QualityScored` with ECE-checked confidence, so ADR-136's fusion engine can weight pose-confidence against vitals-confidence on a common scale, and ADR-140's record carries calibrated uncertainty per field. +- **Cross-device invariance.** `L_calib_robust` keyed on ADR-135 `calibration_id` means a model trained across the fleet (ESP32-S3, C6, cognitum-seed-1) does not learn device-specific shortcuts; embeddings are comparable across nodes — directly enabling multistatic fusion (ADR-029) on encoder embeddings, not just raw CSI. +- **Witnessable inference.** Pure-Rust `f32` ABI extends the ADR-028 proof chain to the full model and ships to Hailo/WASM without libtorch. +- **Ablation-ready.** ADR-145 gets its head toggle for free; the `z`-exposure enables the privacy-leakage probe without bespoke hooks. + +### 3.2 Negative + +- **Weight-export step required.** Training (libtorch) and inference (pure-Rust) now have a mandatory, tested conversion. A bug in `flatten/unflatten` silently degrades inference; W-42 guards it. +- **Loss has more knobs.** `w_h` (seven), `λ_con`, `λ_cal`, `λ_uq` — more hyperparameters to tune; negative transfer between heads is possible and must be monitored via the ablation harness. +- **Relocating `ProjectionHead`** from `wifi-densepose-sensing-server` to `wifi-densepose-nn` touches the serving crate's imports and any RVF segment that referenced the old path. Seeds and layout are preserved so existing RVF embedding indices remain valid, but the move is a real refactor. +- **`ContrastiveBatcher` needs multi-environment data.** `CrossEnvironment` strategy is only meaningful with ≥2 calibrated rooms; with one room it degrades to self-supervised. Until multi-room paired capture exists (CLAUDE.local.md: cognitum-seed-1 + the COM9 node are the two provisioned environments), cross-environment training is data-limited. + +### 3.3 Risks + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Heteroscedastic σ collapses to a constant (head ignores input, learns global noise) | Medium | UQ is uninformative; ECE looks fine but bounds are useless | β-NLL / σ-floor regularization; W-41 ECE test plus a per-input σ-variance assertion | +| Negative transfer: adding count/gait heads degrades pose | Medium | Headline pose metric regresses | ADR-145 ablation matrix quantifies each head's effect on every other; gate head inclusion on no-regression | +| `calibration_id` group too small in a batch → `L_calib_robust` noisy | Medium | Cross-device invariance under-trained | `ContrastiveBatcher` enforces `min_calib_ids ≥ 2` at construction (fail fast) | +| Pure-Rust forward diverges from libtorch training graph (op mismatch) | Low-Med | Inference accuracy ≠ training accuracy | Golden-output parity test: same weights, same input, assert pure-Rust output within tolerance of libtorch reference; part of W-39 | +| Identity/gait heads enabled by default leak biometric data | Medium | Privacy regression | Heads default-off behind `HeadMask`; ADR-141 privacy mode must explicitly enable them; ADR-145 leakage probe verifies residual leakage with them off | + +--- + +## 4. Alternatives Considered + +### 4.1 Separate Models Per Task (status quo) + +Keep pose in the encoder and leave presence/count/activity/vitals/gait as independent signal modules. **Rejected**: no shared representation means no contrastive/cross-environment benefit for the weaker tasks, incomparable confidences (each module invents its own), and every task re-pays the feature-extraction cost. The status quo is precisely the gap §1.1 documents. + +### 4.2 MC-Dropout or Deep Ensembles for Uncertainty + +Sample N stochastic forward passes (MC-dropout) or average M models (ensemble) for predictive uncertainty. **Rejected for the inference path**: N× or M× compute breaks the 20 Hz real-time budget on Pi/Hailo and is impractical in WASM; ensembles also multiply the weight-export and witness-hash surface by M. Heteroscedastic single-pass UQ gives a calibrated band in one deterministic pass. (Deep ensembles remain available as an *offline* evaluation oracle in the ADR-145 harness, not as the shipped UQ.) + +### 4.3 One Multi-Output Head (single MLP emitting everything) + +A single wide head producing all task outputs from `z`. **Rejected**: prevents per-head ablation (§2.6) — you cannot disable count without disabling pose — and forces one loss-weighting compromise. Independent heads are the only structure that satisfies ADR-145's toggle requirement and lets each head own its UQ mechanism (§2.2). + +### 4.4 Keep the ABI as libtorch Tensors End-to-End + +Use `tch::Tensor` for inference too. **Rejected**: not witnessable (non-bit-stable reductions), not deployable to Hailo/WASM, and contradicts the already-shipping pure-Rust `embedding.rs` inference path. The training/inference split with a tested weight-export is the cost of determinism and edge deployment. + +### 4.5 Sample Contrastive Pairs Within a Single Stream (rapid_adapt parity only) + +Reuse only the `Temporal` strategy from `rapid_adapt.rs`. **Rejected as the default**: temporally adjacent positives teach *temporal* smoothness, not *environment* invariance. ADR-027's whole premise is cross-room generalization, which requires `CrossEnvironment` positives spanning `calibration_id`s. `Temporal` is retained as a strategy variant for test-time adaptation parity, not as the training default. + +--- + +## 5.

Strategy Formulations + +### 4.1 Formation Control + +Three modes, selected per mission profile: + +**Mode F1 — Virtual Structure (precision):** +All nodes maintain fixed 3D offsets from a virtual reference frame propagated by the +cluster head. Used for: systematic coverage grids, corridor inspection, coordinated +approach. Fragile to node dropout — use when cluster is stable and mission requires +geometric precision. + +**Mode F2 — Leader-Follower (adaptive):** +One drone follows a computed path; followers maintain ≥ 2 m radial offset from the +leader's trajectory. Used for: linear infrastructure inspection, convoy escort. Leader +failover: RAFT elects new leader from followers within 300 ms. + +**Mode F3 — Reynolds Flocking (emergent):** +Each node applies three rules with tunable weights: +- Separation: repulsion force scales as 1/d² for d < d_min (default 2.5 m) +- Alignment: weighted average heading of k = 6 nearest neighbors +- Cohesion: steering toward centroid of k neighbors + +Extended with: obstacle avoidance (4th rule), OccWorld-informed zone repulsion, goal- +seeking bias toward unscanned probability-map cells. Used for: large-scale area search, +dynamic obstacle environments. No geometric precision guarantee. + +Formation transitions (F1↔F2↔F3) are orchestrated by the cluster head based on mission +phase and swarm health (dropout count, link quality distribution). + +### 4.2 Path Planning + +**Primary: RRT-APF Hybrid** + +An RRT* planner generates globally near-optimal paths per drone. An APF (Artificial +Potential Field) layer provides real-time reactive collision avoidance between planned +paths. Inter-drone path intersections are treated as virtual obstacles in RRT-APF +expansion (MAPF-inspired). Validated at <0.3 s computation time at high obstacle density. + +``` +Input: OccWorld future occupancy grid (ADR-147 output) + Current drone position (UWB + IMU fused EKF) + Task allocation result (target cell or waypoint) + +Stage 1 — RRT* global planner: + Samples free-space voxels from OccWorld occupancy + Builds tree; rewires for shortest path to target + Outputs: waypoint sequence W = [w0, w1, ..., wN] + +Stage 2 — APF reactive layer: + At each timestep: compute repulsion from neighbors + obstacles + Blend APF vector with direction to next waypoint + Max turn rate: 30°/s; max acceleration: 0.5 m/s² + +Stage 3 — Swarm clock collision check: + Broadcast predicted path segments over DDS + Detect spatial-temporal intersections with other drones' paths + Insert virtual obstacle at intersection; replan affected segment +``` + +**Fallback: Boustrophedon (systematic coverage)** +When no target is known (initial area search), each drone receives a partition of the +total area from the cluster head and executes a lawnmower pattern at spacing equal to +2× CSI detection range (~28 m for the RuView Wi2SAR configuration). + +### 4.3 Task Allocation + +**Auction-based with FNN scoring (hybrid):** + +``` +1. Cluster head announces task T (target cell, priority, deadline) +2. Each drone computes bid b_i: + b_i = FNN([dist_to_T, battery_pct, link_quality, csi_confidence, workload]) + FNN: 4-layer (64→32→16→8), ReLU, trained offline with Adam + Output: affinity score ∈ [0, 1]; lower = more capable +3. Drone with lowest b_i (best fit) wins; CH broadcasts assignment +4. If winner fails to acknowledge within 500 ms, second-lowest wins +``` + +For N tasks and M drones simultaneously: solve as assignment problem. Use Hungarian +algorithm for N,M ≤ 20; greedy auction rounds for larger sets. + +Energy-aware constraint: drone with battery < 20% is excluded from new task bids; +assigned RTH (Return to Home) or hover-as-relay role. + +### 4.4 Coverage & Search Strategy + +**Phase 1 — Systematic (high-confidence sweep):** +Partition total area into equal-area cells across active drones. Each executes +boustrophedon at flight altitude h₁ = 30 m, speed 5 m/s. CSI scan width ~28 m. +Lateral overlap 20% for redundancy. No inference during transit — only at waypoints. + +**Phase 2 — Probability-map guided (Bayesian pursuit):** +Each drone maintains a shared probability grid P(x,y) of victim presence. CSI +confidence scores update the grid via Bayesian rule: + +``` +P(victim @ cell) ∝ P(CSI_detect | victim present) × P(victim_prior) +``` + +Drone re-routes to the highest-entropy cell it has not yet visited. Shared grid +disseminated via Gossip; cluster head resolves conflicts on write collision. + +**Phase 3 — Convergence (multi-drone triangulation):** +When P(victim) > 0.75 in any cell: cluster head assigns 3 nearest available drones to +surround the cell at 3 distinct azimuth angles (120° separation). Multi-view CSI fusion +via `ruvector/viewpoint/attention.rs` (CrossViewpointAttention) improves localization +to ≤ 2 m accuracy at 3+ viewpoints. + +**Pheromone map (emergent coordination):** +Virtual pheromone field overlays the probability grid. Drones deposit pheromone on +visited cells; pheromone evaporates at rate τ = 0.98/s. Pheromone steers drones away +from recently scanned areas without central coordination — useful when mesh connectivity +is degraded. + +### 4.5 Emergent Behavior Policies + +| Behavior | Trigger | Local Rule | Emergent Effect | +|----------|---------|-----------|-----------------| +| Lane formation | Corridor width < 2 × d_min | Repel perpendicular; align longitudinal | Orderly single-file or two-lane passage | +| Cluster re-formation | Node count in cluster < 3 | Each drone seeks k≥3 neighbors | Clusters spontaneously merge | +| Collective landing | Battery warning cascade | Nearest-neighbor contagion rule | Full swarm lands within 60 s | +| Relay chain | GCS link SNR < −85 dBm | Intermediate node boosts forward | Self-organizing communication relay | + +--- + +## 5.

Context + +### 1.1 The Gap + +RuView has a mature, deterministic evaluation surface but **no public face for it**. Two assets already exist: + +1. **A grading harness.** `wifi-densepose-train/src/ruview_metrics.rs` rolls pose (PCK@0.2 / OKS / torso jitter / p95 error), tracking (MOTA / ID-switches / fragmentation), and vitals (breathing/heartbeat BPM error + SNR) into a `RuViewAcceptanceResult` with a `RuViewTier` (`Fail` / `Bronze` / `Silver` / `Gold`). ADR-145's `src/ablation.rs` extends this with presence accuracy, localization error, FP/FN, latency p50/p95/p99, a privacy-leakage score ∈ `[0,1]`, and cross-room degradation, under a determinism binding inherited from the ADR-011 proof harness. + +2. **A determinism substrate.** `proof.rs` (`PROOF_SEED=42`) SHA-256-hashes model outputs against an expected hash, so a scored run is reproducible and tamper-evident. + +What is missing is a **public, multi-entrant ranking**. As surveyed in ADR-015 and `docs/research/sota-surveys/sota-wifi-sensing-2025.md`, the WiFi-sensing field has **no hosted live leaderboard** the way vision has COCO/EvalAI — researchers self-report numbers against public *datasets* (MM-Fi, Wi-Pose, Person-in-WiFi, Widar3.0) in papers, with inconsistent splits, metrics, and no privacy or latency accounting. RuView's own pose number (PCK@20 ≈ 2.5% with proxy labels, target 35%+ per ADR-079) is currently self-reported on a private validation set and is not comparable to the MM-Fi SOTA (MultiFormer 0.7225). + +### 1.2 The Opportunity + +The harness that already gates RuView releases is exactly the engine a community leaderboard needs: a single, deterministic, privacy- and latency-aware scoring function. Publishing it as an open leaderboard: + +- Establishes **AetherArena as the field's standard yardstick** for spatial intelligence, with RuView's `RuViewTier` + ADR-145 metric set contributed as its initial basis (pose + tracking + vitals + **privacy-leakage** + latency + determinism — a combination no existing benchmark scores). The standard is AA's; RuView donates the seed. +- Draws **any project, framework, or modality** to submit and rank — a cross-project community flywheel, not a RuView-only one (RuView's `wifi-densepose-pretrained` is merely the first baseline). +- Forces the harness to harden: a public, neutral scorer must be reproducible by strangers, resistant to gaming, and runnable on a fixed held-out split nobody can train on. + +### 1.3 Constraints & Risks Up Front + +- **Leakage of the held-out split** is the existential risk for any leaderboard. The eval data must be private; submitters provide a model, not predictions on data they hold. +- **Compute cost.** Scoring a submission runs inference over the eval set; an HF Space on free CPU may be too slow for the Candle/`tch` pipeline. Tiering of compute (CPU smoke vs GPU full score) is required. +- **Privacy / consent of the eval data.** MM-Fi and Wi-Pose carry their own licenses; we can host *derived* CSI features and scores but must respect redistribution terms (ADR-015 already tracks this). +- **Trust.** A `RuViewTier` badge is only meaningful if the scoring is deterministic and the leaderboard cannot be silently edited — the ADR-011 proof hash and a signed results ledger address this. + +--- + +## 2. Decision + +**Create AetherArena ("AA") — the official, project-agnostic Spatial-Intelligence Benchmark: a public, open-entry leaderboard for camera-free spatial perception (pose, presence, occupancy, tracking, vitals) as a standalone repo `ruvnet/aether-arena` paired with a Hugging Face Space. The scoring engine is seeded by RuView's existing `ruview_metrics` + ADR-145 ablation harness, contributed as a neutral scorer; v0 evaluates against a private MM-Fi held-out split.** + +AA is **not a RuView leaderboard**. It is the field's missing standard yardstick for spatial intelligence — open to any team, framework, or sensing modality. The RF medium is the v0 input and RuView donates the seed harness + a baseline entry, but the benchmark is independent and RuView is scored like every other entrant. The metric surface — pose, presence, tracking, occupancy/world-model, latency, determinism, and later privacy — is modality-agnostic, leaving room to grow to mmWave / UWB / radar / lidar / multimodal entrants and other projects. + +The leaderboard does **not** fork or re-implement the scoring logic.

Non-commercial use + derivatives **permitted with attribution**. AA may host *derived* CSI features and scores; raw frames stay in the private split. AA must be operated **non-commercially** and carry MM-Fi attribution. | +| **Wi-Pose** | **"Research use"** (no clean redistribution grant) | ⚠️ **Not hosted.** Pulled privately into the scorer only, never redistributed; or deferred until terms are clarified with the authors. **Dropped from v0.** | +| Person-in-WiFi-3D | semi-public access | Future candidate (post-v0), pending access terms. | + +**v0 decision:** evaluate on a **private MM-Fi held-out split only** (CC BY-NC, attributed, non-commercial; expose only license-permitted derived features). Wi-Pose is removed from v0 and revisited if/when redistribution is cleared. This keeps the existential "can we even host this" risk at zero for launch. + +> **Non-commercial caveat to watch:** CC BY-NC means AA itself, and the eval-data use, must remain non-commercial. Because AA also showcases the (commercial) RuView appliance, keep AA legally distinct and non-commercial, or seek an MM-Fi commercial grant before any paid tier. Flagged for the maintainer. + +### 2.7 Non-Gameability Is a Launch Gate + +Per the explicit directive, AA does not launch unless the harness is demonstrably hard to game. The controls (private split §2.4, seasonal rotation §2.4, model-not-prediction submission §2.2, sandbox §2.4, pinned `harness_version` §2.4, signed append-only ledger §2.3-§2.4, multiplicative `arena_score` §2.5, `determinism_gate=0` on proof-hash failure §2.5) are **not optional hardening — they are acceptance criteria** (see §7). A v0 that can be topped by overfitting a public split, a non-reproducible run, or a silently edited row is, by definition, not ready. + +### 2.8 Neutrality & Governance (because it's "official" and cross-project) + +The hardest credibility problem for an *official* benchmark seeded by one entrant: **"RuView built the scorer, so of course RuView wins."** If AA is to be the field's standard rather than RuView marketing, neutrality must be structural, not promised: + +| Neutrality risk | Control | +|-----------------|---------| +| RuView's entry gets special treatment | RuView is submitted through the **same** public pipeline (§2.2.1) and scored by the **same** pinned scorer as everyone else; its rows carry the same proof hash and are independently re-runnable on the smoke split. | +| RuView tunes the metric to favor its models | The scorer is **open and versioned**; any metric change is a public `harness_version` bump that **re-scores all entries**, not just new ones. Metric changes go through a public changelog. | +| "Official" is self-declared | AA is positioned as a **neutral commons**: separate repo/Space identity, contribution guide, and an explicit invitation for other projects + dataset authors to co-own splits and metrics. RuView is the *donor of the seed harness*, not the owner of the standard. | +| Benchmark used as RuView ad | Keep AA legally + brand-distinct (ties into the CC BY-NC non-commercial caveat, §2.6); the README leads with the standard, not the product. | +| Single-vendor capture | Roadmap to a multi-org steering/eval committee once ≥N external projects enter; split rotation + metric proposals are public. | + +The test for neutrality is the same as §7's acceptance test: a stranger from *another project* can submit, reproduce the score, and see that RuView's own entries were scored by the identical, open, pinned path. + +--- + +## 3. Consequences + +### 3.1 Positive +- A real, comparable public number for RuView (and everyone else) on MM-Fi / Wi-Pose, scored by a privacy- and latency-aware harness no other WiFi benchmark offers. +- Community flywheel: external models/adapters get ranked, feeding `ruvnet/wifi-densepose-pretrained`. +- Forces the harness to be reproducible-by-strangers, which strengthens internal release gating too. + +### 3.2 Negative / Costs +- **New repo + HF Space to maintain**, incl. a scoring container and queue. Ongoing compute cost (mitigate: CPU smoke-score on submit, batched GPU full-score on a schedule). +- **Dataset licensing** must be cleared for hosting derived MM-Fi / Wi-Pose features (ADR-015 owns this; may require contacting dataset authors). +- **Abuse surface** (malicious model artifacts run in the scorer) — must sandbox the container (no network, read-only eval data, resource caps). + +### 3.3 Neutral +- The scoring logic stays in `wifi-densepose-train`/`-cli`; the leaderboard is presentation only, so it does not bloat the core workspace. + +--- + +## 4. Alternatives Considered + +1. **Submit RuView to existing venues only (MM-Fi GitHub, Papers-with-Code).** Lower effort, but no privacy/latency axes, no live entry, and RuView doesn't own the standard. *Complementary, not exclusive — we should still post MM-Fi numbers.* +2. **A static numbers page in the RuView README.** Zero infra, but not multi-entrant and not a leaderboard. +3. **EvalAI / Kaggle competition.** Stronger anti-gaming infra, but heavyweight, time-boxed, and off-brand vs an always-open HF Space next to the model. + +--- + +## 5. Open Questions + +1. **Eval data hosting** — can we redistribute derived MM-Fi / Wi-Pose CSI features under their licenses, or must scoring pull the raw datasets the submitter cannot see? (Owner: ADR-015 follow-up.) +2. **Compute budget** — free HF CPU Space, ZeroGPU, or a self-hosted scorer on the GCloud A100/L4 fleet (`cognitum-20260110`)? +3. **Name lock** — confirm `aether-arena` vs `wifi-densepose-leaderboard`. +4. **Season cadence** — does the held-out split rotate monthly, and do we keep an all-time + per-season board? +5. **Privacy-leakage attack** — ship the membership-inference attacker (ADR-145 §10 is currently a *defined-but-unimplemented* metric) before launch, or launch with privacy as a "coming soon" axis? + +--- + +## 6. Implementation Sketch (if accepted) + +- **P1** — Stand up `ruvnet/aether-arena` repo + skeleton Gradio HF Space; define `ruview-arena.toml` submission contract; publish a **public smoke split** a stranger can score locally. +- **P2** — Containerize `wifi-densepose-cli score` as the pinned, sandboxed scorer (no network, read-only FS, caps); wire the signed append-only Parquet ledger + `determinism_gate`. +- **P3 — v0 LAUNCH (narrow).** Clear + load the private MM-Fi / Wi-Pose held-out split; activate **Presence, Pose, Edge-latency, Determinism** categories; seed the board with RuView's own `wifi-densepose-pretrained` baseline (honest current PCK@20).

Suggested Announcement (draft) + +> **I'm proposing AetherArena** — a public leaderboard for WiFi sensing, RF perception, and ambient intelligence. +> +> The problem with this field is not just model quality. It is *measurement* quality. Most WiFi-sensing work reports numbers against datasets with inconsistent splits, inconsistent metrics, and almost no accounting for latency, privacy leakage, reproducibility, or edge viability. +> +> AetherArena fixes that. Models are submitted, scored in a pinned sandboxed container against **private** held-out MM-Fi and Wi-Pose splits, and written to a **signed append-only** results ledger. The scoring engine reuses the same RuView harness we use internally: pose, presence, tracking, vitals, latency, cross-room degradation, deterministic proof hashes — and, once its attacker ships, privacy leakage. +> +> The goal is not to make RuView look good. The goal is to make the *category* measurable. If ambient intelligence is going to move from demos to infrastructure, it needs public numbers, reproducible commands, private eval splits, and failure modes that cannot be hidden. + +### Strategic note — three layers of the credibility story + +| Layer | Asset | +|-------|-------| +| Retrieval credibility | ruflo BEIR harness | +| Sensing credibility | **AetherArena (this ADR)** | +| Product credibility | RuView appliance + Arista-style deployments | diff --git a/docs/adr/ADR-150-rf-foundation-encoder.md b/docs/adr/ADR-150-rf-foundation-encoder.md new file mode 100644 index 0000000000..bb80ab2545 --- /dev/null +++ b/docs/adr/ADR-150-rf-foundation-encoder.md @@ -0,0 +1,260 @@ +# ADR-150: RuView RF Foundation Encoder — pose-preserving, subject/room/device-invariant CSI embedding + +| Field | Value | +|-------|-------| +| **Status** | Proposed | +| **Date** | 2026-05-30 | +| **Deciders** | ruv | +| **Codebase target** | New `wifi-densepose-rfencoder` (or `nn/src/rf_foundation.rs`) + training in `wifi-densepose-train`; consumed by the MM-Fi pose head and the AetherArena Generalization Track (ADR-149) | +| **Relates to** | ADR-024 (Contrastive CSI Embedding / AETHER), ADR-027 (Cross-Environment Domain Generalization / MERIDIAN), ADR-134 (CIR), ADR-135 (calibration + coherence gate), ADR-145 (Ablation/Eval Harness), ADR-149 (AetherArena benchmark) | + +--- + +## 1.

ADR-150 documents the wall directly: an MM-Fi pose head scores **81.63% torso-PCK@20 in-domain but ~11.6% leakage-free cross-subject**, and bigger capacity *hurts* cross-subject (transformer 24.8% < conv 27.3%). A single oversized model that "understands the world" overfits the rooms and bodies it has seen. The lever is the opposite of scale: **a small model that understands *one* room and *one* person**, calibrated in minutes, run locally, and specialised per biological signal. + +This positions RuView between the two incumbents in ambient sensing: + +- **Wearables** — high fidelity, but people forget to wear them, and they only measure the wearer. +- **Cameras** — powerful, but invasive, store identifiable video, and fail in the dark / under covers. + +RuView sits in the middle: it learns the *space*, learns the *person*, and tracks biological rhythm (breathing, heartbeat, restlessness, posture, presence) without seeing skin or storing video. Heartbeat and breathing are not visual problems — they are tiny, repeating disturbances in the RF field.

Every specialist is a small head over its embedding — so the marginal cost of a sixth specialist is kilobytes of LoRA weights, not another full model. + +### 2.2 Stage 2 — the guided enrollment protocol (NEW) + +`EnrollmentProtocol` is a CLI-driven state machine that walks the operator through a fixed sequence of labelled **anchors**. The design rule from the user vision is explicit: *clean anchors, not hours of data.* Each anchor is a short (default 20 s @ 20 Hz = 400 frames) labelled clip captured against the already-recorded baseline. + +| Anchor | Label | Duration | Primary signal taught | Feature emphasis | +|--------|-------|----------|-----------------------|------------------| +| `empty` | presence=0 | (reuse ADR-135 baseline) | absence reference | amplitude variance floor | +| `stand_still` | posture=standing, presence=1 | 20 s | static human load | amplitude mean shift, eigenmode delta | +| `sit` | posture=sitting | 20 s | lower static load | amplitude profile | +| `lie_down` | posture=lying | 20 s | sleep-position load | amplitude profile, low Doppler | +| `breathe_slow` | resp≈0.1–0.15 Hz | 30 s | slow respiration | periodicity, micro-Doppler | +| `breathe_normal` | resp≈0.2–0.3 Hz | 30 s | normal respiration | periodicity, BVP phase | +| `small_move` | motion=1 | 20 s | limb micro-motion | Doppler spread, variance | +| `sleep_posture` | posture=lying, restless=0 | 30 s | quiescent sleep baseline | long-window variance, timing | + +The protocol is **adaptive**: an anchor is only accepted when its captured features pass a quality gate (coherence ≥ threshold from `coherence_gate.rs`, sufficient SNR vs baseline, no saturation). A failed anchor is re-prompted rather than silently kept — bad anchors poison small models far more than large ones. Total guided enrollment is ~4 minutes of wall-clock, producing 8 clean anchors. This is intentionally far below the "hours of data" that a from-scratch model needs, because the backbone already carries world knowledge; enrollment only teaches *this* room's offsets. + +Anchors are persisted as an append-only `EnrollmentSession` (event-sourced, per CLAUDE.md state rules) under `room_id`, so re-enrollment is incremental and auditable. + +### 2.3 Stage 3 — feature extraction to labelled records (REUSE + bridge) + +Each accepted anchor clip is run through the existing extractor stack, baseline-subtracted per ADR-135, and packaged into an `AnchorFeature` record. No new DSP is invented — this stage is a *bridge*, not a new algorithm. + +| Feature group | Source module | Used by specialists | +|---------------|---------------|---------------------| +| CSI amplitude mean/variance | ADR-135 baseline subtraction + `signal_features.rs` | presence, posture | +| CSI phase (sanitised, LO-aligned) | `phase_sanitizer` → `phase_align` | posture, heartbeat | +| Doppler shift / micro-Doppler | `ruvsense/bvp.rs`, `breathing` path | breathing, small-move | +| Micro-motion / intention lead | `ruvsense/intention.rs` | restlessness, anomaly | +| Periodicity / spectral peaks | `bvp.rs` autocorrelation + FFT | breathing, heartbeat | +| Long-window variance / drift | `ruvsense/longitudinal.rs` (Welford) | restlessness, presence | +| Timing / inter-frame epoch | `c6_timesync` epoch, frame Δt | all (rhythm alignment) | +| Field eigenmode coefficients | ADR-030 `field_model.rs` | posture, presence | + +`AnchorFeature` = `{ room_id, anchor_label, t_epoch_us, embedding: [f32; D] (backbone output), aux: { resp_hz?, doppler_spread, variance, periodicity_score, eigen_coeffs } }`. The backbone embedding is the *shared* representation; `aux` carries the cheap hand-features that let small heads specialise without re-learning DSP. + +### 2.4 Stage 4 — the specialist bank (NEW, the core contribution) + +A **`SpecialistBank`** is a versioned collection of small models scoped to one `room_id`, persisted as a single RVF cognitive container (`wifi-densepose-ruvector`). Each specialist is a *head* over the frozen backbone embedding, trained from the labelled `AnchorFeature` records via the existing `rapid_adapt.rs` LoRA machinery (test-time/few-shot training, contrastive + entropy losses), **not** a from-scratch network. + +| Specialist | Model type | Params (typ.) | Label source | Output | +|------------|-----------|---------------|--------------|--------| +| **breathing** | 1-D temporal head + periodicity regressor | ~8 KB LoRA + aux | `breathe_slow`/`breathe_normal` | resp rate (Hz) + confidence | +| **heartbeat** | narrowband phase head (harmonic-aware) | ~12 KB | quiescent anchors + periodicity | HR (bpm) + confidence | +| **sleep restlessness** | variance/drift classifier | ~4 KB | `sleep_posture` vs `small_move` | restlessness score [0,1] | +| **posture** | k-way prototype classifier (HNSW NN) | prototypes only | `stand/sit/lie` anchors | posture class + margin | +| **presence** | binary energy/eigenmode gate | ~2 KB | `empty` vs occupied anchors | presence prob | +| **anomaly** | one-class / physically-impossible detector (`adversarial.rs`) | ~6 KB | baseline + all anchors (novelty) | anomaly score + veto flag | + +Design properties that follow from invariant (A): + +- **Independently versioned & swappable.** Re-enrolling breathing does not retrain posture. A specialist carries its own `{trained_at, anchor_set_hash, baseline_hash, backbone_rev}`. +- **HNSW prototype storage for the classifiers.** Posture and presence are nearest-prototype lookups in the RVF index — no inference engine, microsecond latency, and new postures are added by inserting a prototype, not retraining. +- **SONA online adaptation.** Each specialist may carry a SONA/MicroLoRA online-adaptation slot (`ruvllm_sona_*` / `microlora` primitives) so it tracks slow drift (furniture moved, seasonal RF change) between full re-enrollments, gated by ADR-135 baseline drift. +- **Teacher–student distillation (optional, offline).** Where a labelled public corpus exists (MM-Fi, Wi-Pose), the ADR-150 backbone acts as teacher to pre-shape a head before per-room fine-tuning, improving cold-start. The *teacher* is global/HF; the *student head* is local. + +**Invalidation contract.** The bank stores the `baseline_id` (the baseline UUID) it was trained against. **As implemented**, the runtime marks the bank `STALE` whenever the *current* baseline id differs from the trained one — a conservative trigger that catches re-calibration (room rearranged, AP moved, band changed) because any of those produces a new baseline. A finer **drift-threshold** trigger (mark STALE when ADR-135's per-subcarrier deviation exceeds τ *without* a full re-baseline) is a planned refinement (P6). Either way the runtime prompts re-enrollment rather than emitting silently wrong vitals — the calibration analogue of the #954 `DEGRADED` honesty rule: never report confident numbers from an invalid model. + +### 2.5 Runtime — mixture of specialists with confidence gating + +At inference, the frozen backbone embeds each CSI window once; every specialist consumes that shared embedding and emits `{value, confidence}`. Fusion rules: + +- The **anomaly** specialist holds a **veto**: a high anomaly score (physically-impossible signal per `adversarial.rs`, or a coherence-gate `Reject`) suppresses positive vitals/posture output and raises a flag, rather than propagating a hallucinated reading. +- **presence=0** short-circuits breathing/heartbeat/posture to `null` (you cannot have a respiration rate in an empty room). +- Each emitted reading is tagged with the specialist's confidence and the `baseline_hash`/`backbone_rev` provenance, so downstream consumers (sensing-server, MQTT, Home Assistant) can gate on quality — consistent with ADR-135 coherence-gate semantics. + +### 2.6 Crate & module layout + +New bounded-context crate `wifi-densepose-calibration` (orchestration only; files < 500 lines, typed public APIs, event-sourced sessions — per CLAUDE.md): + +``` +wifi-densepose-calibration/ + src/ + lib.rs # public API: CalibrationSystem facade + enrollment.rs # EnrollmentProtocol state machine (Stage 2) + anchor.rs # Anchor, EnrollmentSession (event-sourced) + extract.rs # AnchorFeature bridge over signal_features + ruvsense (Stage 3) + specialist.rs # Specialist trait, SpecialistKind enum + bank.rs # SpecialistBank (RVF container, versioning, invalidation) + runtime.rs # MixtureOfSpecialists fusion + veto (Stage 5) + backbone.rs # frozen ADR-150 encoder loader (hf_hub from_pretrained, cached) + error.rs +``` + +Dependencies (no duplication — orchestrates existing crates): `wifi-densepose-signal` (ruvsense extractors, ADR-135 baseline), `wifi-densepose-train` (`rapid_adapt`, `signal_features`, `trainer`), `wifi-densepose-ruvector` (RVF, HNSW), `wifi-densepose-nn` (backbone inference).

The environmental fingerprint and the person-specific heads stay local; no video, no skin, no cloud round-trip. This is the core differentiator vs cameras and the convenience differentiator vs wearables. +- **Minutes, not hours.** Because the backbone carries world knowledge, ~4 minutes of clean anchors calibrates a room. Re-enrollment is incremental. +- **Honest degradation.** The `baseline_hash` invalidation + anomaly veto mean an out-of-calibration room reports `STALE`/flagged rather than confidently wrong — the same honesty principle as the firmware `DEGRADED` flag. +- **Composable & cheap to extend.** A new biological signal = a new small head over the same embedding, not a new model. + +### 3.2 Negative / risks + +- **Backbone dependency.** Every specialist rides on ADR-150's encoder; its quality and revision compatibility (`backbone_rev`) are a single point of leverage. Mitigation: pin `backbone_rev` in each specialist; distillation cold-start reduces sensitivity. +- **Enrollment burden.** 4 minutes is small but non-zero, and anchor quality depends on the operator following prompts. Mitigation: adaptive re-prompting + quality gates; ship sane defaults so a partial bank (presence+posture) works after just the static anchors. +- **Heartbeat is hard.** Sub-mm chest displacement at HR frequencies is near the ESP32-S3 noise floor; the heartbeat specialist will have lower and more variable confidence than breathing. The confidence-gated runtime surfaces this rather than faking it. +- **Per-room storage proliferation.** A bank per room per person; needs a clear RVF lifecycle (list/prune/export) — handled by `bank.rs` versioning and the `room-status` CLI. + +### 3.3 Alternatives considered + +| Alternative | Verdict | Reason | +|-------------|---------|--------| +| One large general model for all signals | **Rejected** | The ADR-150 evidence: scale overfits rooms/subjects and collapses cross-domain; also slower, costlier, less private.

The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`tests/full_loop.rs`: clean baseline with zero motion flags, 8/8 anchors through the quality gate, 6 specialists trained, JSON bank round-trip, trained-bank inference 18±2 BPM positive / absent negative / foreign-baseline STALE; seed-robust). The one live runtime signal (breathing ~16–31 BPM via `room-watch`) used the *stateless* breathing head, **not** a trained bank; the clean empty-room loop has **not** yet run on-target — the remaining gap is strictly the hardware session (empty room + operator anchors). The four behavioral findings from the full-loop test (z-band squeeze, variance-only presence, ungated hz embedding, heart-band lag-floor leakage) are FIXED and regression-guarded — see the integration doc §7.

Almost all performance numbers are author-self-reported preprint results — treated here as CLAIMED until reproduced on our hardware. + +### 1.1 The five verified findings + +**(F1) "Coordinate overfitting" is a named, diagnosed failure mode of camera-supervised WiFi pose — and our ADR-079 pipeline has the exact shape of it.** +PerceptAlign (arXiv [2601.12252](https://arxiv.org/abs/2601.12252), accepted ACM MobiCom 2026) shows that models regressing CSI directly to camera-frame coordinates memorize the deployment-specific transceiver layout; SOTA baselines degrade to >600 mm MPJPE in unseen scenes. Their fix is cheap: a <5-minute calibration using two checkerboards and a few photos to align WiFi and vision in one shared 3D frame, plus **fusing transceiver-position embeddings with CSI features**. Claimed: −12.3% in-domain error, −60%+ cross-domain error. They release the claimed-largest cross-domain 3D WiFi pose dataset (21 subjects, 5 scenes, 18 actions, **7 device layouts**). *Evidence: improvements CLAIMED (preprint w/ MobiCom acceptance); the failure mode itself is corroborated across the cross-domain literature — and independently by our own ADR-150 data (81.63% in-domain vs ~11.6% leakage-free cross-subject torso-PCK).* + +**(F2) An external model named "WiFlow" claims 97.25% PCK@20 with 2.23M params and ships everything.** +arXiv [2602.08661](https://arxiv.org/abs/2602.08661) (Apr 2026) — spatio-temporal-decoupled CSI pose, 97.25% PCK@20 / 99.48% PCK@50 / 0.007 m MPJPE, 2.23M parameters (~2.2 MB int8). Code, pretrained weights, and a 360k-sample CSI-pose dataset are public under Apache-2.0 ([repo](https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling), Kaggle dataset). *Evidence: artifact availability MEASURED (verified by direct repo inspection); PCK numbers CLAIMED (5-subject, in-domain, self-collected dataset; hardware unspecified; 15 keypoints vs our 17).* ⚠️ **Name collision:** this is unrelated to RuView's internal WiFlow model. In all RuView docs the external model is referred to as **WiFlow-STD (DY2434)**. + +**(F3) For CSI foundation encoders, data scale — not model capacity — is the bottleneck, and the tokenization recipe is now known.** +UNSW's MAE pretraining study (arXiv [2511.18792](https://arxiv.org/abs/2511.18792), Nov 2025) — the largest heterogeneous CSI pretraining run to date (1,320,892 samples, 14 public datasets incl. MM-Fi, Widar 3.0, Person-in-WiFi 3D; 4 devices; 2.4/5/6 GHz; 20–160 MHz) — reports zero-shot cross-domain gains of 2.2–15.7% over supervised baselines, with unseen-domain performance scaling **log-linearly with pretraining data, unsaturated at 1.3M samples**, while ViT-Base adds only 0.4–0.9% over ViT-Small. Optimal recipe: **80% masking ratio, small (30,3) patches** (+4.7% over (40,5) by preserving fine temporal dynamics). *Evidence: MEASURED within-study (ablations verified in body text) but preprint; downstream tasks are classification, NOT pose — pose transfer is a hypothesis. Independently corroborates ADR-150's finding that capacity hurts cross-subject.* + +**(F4) Hardware/standards: 802.11bf is finished; Espressif ships official sensing; Wi-Fi 6 AP CSI is reachable.** +- **IEEE 802.11bf-2025** published **2025-09-26** (verified against the IEEE SA record) — sensing standardization is complete for both sub-7 GHz and >45 GHz, with formal sensing setup/feedback procedures. No ESP32 silicon implements it yet. *Evidence: MEASURED (standards-body record).* +- **Espressif `esp_wifi_sensing`** (Apache-2.0, v0.1.x, ESP Component Registry): official CSI presence/motion FSM; esp-csi actively maintained (commit 2026-04-22, verified), CSI confirmed across ESP32/S2/C3/S3/C5/C6/C61. *Evidence: MEASURED (vendor pages + commit log).* ⚠️ A stronger "drop-in compatible with RuView nodes" claim was **REFUTED 0-3** — WiFi-6 parts use a different CSI acquisition config struct. +- **ZTECSITool** (arXiv [2506.16957](https://arxiv.org/abs/2506.16957), [code](https://github.com/WiFiZTE2025/ZTE_WiFi_Sensing)): CSI from commercial Wi-Fi 6 APs at up to 160 MHz / 512 subcarriers (~5–10× ESP32 subcarrier count; the gain is aperture, not per-Hz granularity). Firmware is gated behind a ZTE serial-number approval. *Evidence: capability CLAIMED by the vendor-authored tool paper; code artifact MEASURED.* + +**(F5) Nothing in 2025–2026 does full DensePose UV regression from commodity WiFi.** Keypoint pose remains the field's frontier. Three "wireless foundation model" papers were screened out by full-text inspection (HeterCSI = simulated cellular channels only; the NeurIPS-2025 FMCW pilot = mmWave radar, presence-only; arXiv 2509.15258 = survey, no artifacts). *Evidence: MEASURED (absence verified by full-text inspection of the candidates that surfaced; absence of evidence across the whole literature is necessarily weaker).* + +### 1.2 What this means for the ADR-151 calibration system + +ADR-151's enrollment protocol captures guided human anchors but does **not** record or condition on transceiver geometry. F1 says that omission is precisely the thing that makes camera-supervised (and, plausibly, anchor-supervised) heads layout-brittle. ADR-151's per-room thesis ("teach the room before you teach the model") is *strengthened* by F1 — PerceptAlign is independent evidence that layout must be modeled explicitly — and the fix composes naturally with our Stage-2 enrollment. + +ADR-150's masked-CSI-encoder design is *validated* by F3, which also hands us the hyperparameters and the priority call: **collect/aggregate more heterogeneous CSI before scaling the encoder.** + +## 2. Decision + +Adopt four changes, ordered by effort-vs-gain: + +### 2.1 Geometry-condition the calibration system (extends ADR-151 Stage 2) — ACCEPTED + +1. **Record transceiver geometry at enrollment.** `EnrollmentProtocol` gains an optional `NodeGeometry` record per node (position estimate, antenna orientation, inter-node distances where known). Stored alongside the room baseline in the bank; schema-versioned so existing banks remain readable. +2. **Fuse geometry embeddings into specialist training.** Where a specialist head consumes the (future, ADR-150) backbone embedding, concatenate a small learned embedding of `NodeGeometry` — the PerceptAlign mechanism, transplanted to our per-room banks. Statistical specialists (current) ignore it; LoRA heads (ADR-151 P6) consume it. +3. **Adopt the two-checkerboard alignment for the camera-supervised path (ADR-079).** When MediaPipe supervision is used, calibrate camera↔WiFi into one shared 3D frame before regression (<5 min, two checkerboards, a few photos). This is the direct defense against F1 for our camera-supervised pipeline. ~~92.9%-PCK@20~~ — *that figure was retracted during measurement (b) (2026-06-10): the surviving holdout shows a constant-output model under an absolute (non-torso) threshold on 69 near-static frames; mean predictor scores 100% under the same protocol. The §2.2 no-citation rule now applies to it.* +4. **Evaluate on the PerceptAlign cross-domain dataset** (21 subjects / 7 layouts) as the MERIDIAN cross-layout benchmark — *gated on confirming its license and downloadability* (open question; repo per paper: github.com/Trymore-lab/PerceptAlign). + > **Gate resolved (2026-06-10, MEASURED by repo inspection):** repo exists, **MIT license**, dataset downloadable from HuggingFace (5 per-scene repos, raw CSI + separate vision keypoints; Intel 5300, 1TX×3RX×3 ant, 57 subcarriers — same order as ESP32 subcarrier counts; Scene3 ships 3 distinct layouts). Code present, no pretrained weights. Benchmark adoption unblocked; dataset-side license terms inherit HF dataset terms (not separately stated — check at download time). + +### 2.2 Benchmark against WiFlow-STD (DY2434) — ACCEPTED + +Pull the Apache-2.0 weights + 360k-sample dataset; run three measurements: (a) their model on their data (reproduce 97.25% claim), (b) their model fine-tuned on our ESP32 17-keypoint eval set, (c) our internal WiFlow on their dataset (15-keypoint subset mapping). Until (a)–(c) are measured, **no RuView doc may cite 97.25% as a comparable number** — different dataset, subjects, keypoints. + +> **Status (2026-06-10, measurement (a) complete — `benchmarks/wiflow-std/RESULTS.md`):** shipped checkpoint REFUTED (0.08% PCK@20 — wrong keypoint normalization, predates published code); released code does not run as published (6 defects, incl. broken package import and an unreachable test phase); released dataset's last 13 files are corrupted (9,072 windows: NaN + float32-max garbage, diverges fp16 training via BatchNorm poisoning). After repairing both, retraining with upstream defaults reproduced **96.09% PCK@20 full-test / 96.61% corruption-free / MPJPE 0.0094–0.0098** (published: 97.25% / 0.007) on an RTX 5080. Accuracy claims graded MEASURED-EQUIVALENT; params (2.23M) and FLOPs (~0.055G) verified. (b)/(c) remain open. + +### 2.3 Apply the UNSW recipe to the ADR-150 encoder — ACCEPTED (amends ADR-150 §2.3) + +- Pretraining corpus: start from the same 14 public datasets (1.3M samples) + our home/MM-Fi frames; data aggregation takes priority over architecture work. +- Tokenization: 80% masking, (30,3)-class small patches; encoder stays ViT-Small-class (~15M params) — F3 and our own DANN/transformer results agree that capacity does not pay. +- The published log-linear scaling (unsaturated) sets the expectation: more heterogeneous CSI in, better zero-shot out. + +### 2.4 Hardware watch items — ACCEPTED (no code now) + +- **802.11bf**: track silicon/certification; OTA binding remains deferred until commodity chipsets expose standardized sensing measurements. **Amended by ADR-153** (2026-06-10): implement a pure Rust forward-compatibility protocol layer now — typed procedure models, a deterministic session FSM, a transport abstraction, simulation tests, and an `OpportunisticCsiBridge` that maps today's ESP32 CSI batches into standardized sensing-report shape. +- **esp_wifi_sensing**: benchmark our presence pipeline against the vendor FSM (one afternoon; useful external baseline). Do **not** treat as drop-in (refuted claim). +- **ZTECSITool AP**: optional high-resolution anchor node for the ADR-029 multistatic mesh — procurement-gated; only pursue if a 160 MHz anchor materially helps tomography. + +### 2.5 Explicitly NOT adopted + +- No pivot toward "wireless foundation model" papers that don't ship WiFi-CSI artifacts (HeterCSI, FMCW pilot, surveys). +- No DensePose-UV work item: the field has not demonstrated UV regression from commodity WiFi; keypoints remain our supervised target (F5). + +### 2.6 RuVector vendor sync + integration opportunities (added 2026-06-10) + +**Vendor sync record.** `vendor/ruvector` moved from pin `e38347601` (2026-05-07) to `a083bd77f` (origin/main, 3 commits past tag `ruvector-v0.2.28`; vendored workspace version 2.2.3). 111 commits in the range, roughly half NAPI-binary/lint chores.

(§2.2 answers this.) + > **Partial answer (MEASURED 2026-06-11, measurement (b) on 2,046 single-room windows — `benchmarks/wiflow-std/RESULTS.md`):** pretrained init shows strong *optimization* transfer (65% PCK@20 vs scratch's 0% collapse under the same budget) but **no feature transfer** (frozen-trunk + linear adapter ≈ 0%). And no run beat the mean-pose baseline (95.9% PCK@20 — single subject, near-static normalized coords), so no CSI→pose capability is citable from this data. A definitive answer needs multi-subject/multi-position data where the mean pose is weak. +2.

The headline finding — the ADR-134 CIR coherence gate was DEAD in production (CRITICAL, FIXED) + +### 2.1 What was wrong + +`MultistaticFuser` fuses **canonical CSI frames**: `hardware_norm.rs` resamples every chipset onto a uniform **56-tone canonical grid** before fusion (`HardwareNormalizer`, default `canonical_subcarriers = 56`). The ADR-134 CIR coherence gate (`cir_gate_coherence`, multistatic.rs) is supposed to blend a CIR dominant-tap ratio into the cross-node coherence — `coherence = 0.7·freq + 0.3·dominant_tap_ratio`. + +But the gate was wired to `CirEstimator::new(CirConfig::ht20())` (`with_cir_ht20`), and `ht20()` expects **64 FFT bins or 52 active tones**. A canonical-56 frame matches *neither*, so every call returned `CirError::SubcarrierMismatch` and `cir_gate_coherence` hit its **silent `Err(_) => freq_coherence` fallback** (multistatic.rs). Net effect: **the CIR gate never ran on a single production frame** — `use_cir_gate = true` was indistinguishable from `false`. This is the exact shape of "AI slop": a feature that compiles, has tests on the *estimator*, and is dead at the *integration seam*. + +### 2.2 The fix (the gate now actually runs) + +- New `CirConfig::canonical56()` (cir.rs): 64-bin HT20 framing, **56 active tones**, 168 delay taps, Φ built over a contiguous −28..+28 active-tone grid (also the native Atheros-56 layout). `bandwidth_hz`/`tap_spacing` stay physically correct for a 20 MHz HT20 channel; only the active-tone count differs from `ht20()`. +- New `MultistaticFuser::with_cir_canonical56()` — the **correct default** for the RuvSense pipeline. `with_cir_ht20()` is retained for genuine raw-64/52 feeds and now carries a loud doc-warning. +- `active_indices()` handles `(64, 56)` explicitly and the fallback now selects the slice whose length matches `num_active` (so Φ's column count is always self-consistent — no silent fall-through to the 52-index slice). +- The remaining silent fallback is made **LOUD**: a `SubcarrierMismatch` inside `cir_gate_coherence` now fires a `debug_assert!` naming the misconfiguration ("CIR gate DEAD … build it with `CirConfig::canonical56()`"). A *config* error can no longer hide as a graceful runtime degrade. +- `cir_estimate_first()` exposes the raw `estimate()` verdict so a test can **count Ok vs Err** on a canonical-56 stream. + +### 2.3 The PROOF (committed regression tests, `ruvsense::multistatic::tests`) + +| Test | Asserts | Result | +|------|---------|--------| +| `cir_gate_ht20_is_dead_on_canonical56` | old ht20 estimator on 8 canonical-56 frames → **0 Ok, 8 `SubcarrierMismatch`** | the dead gate, measured | +| `cir_gate_canonical56_is_alive` | new canonical56 estimator on the same 8 frames → **8 Ok, 0 Err** | the gate runs | +| `cir_gate_on_changes_coherence_vs_off` | `coherence(gate on)` ≠ `coherence(gate off)` (\|Δ\| > 1e-6) | the CIR term is actually applied | +| `cir_gate_dead_ht20_equals_gate_off` (release-only) | dead-ht20 coherence == gate-off coherence (\|Δ\| < 1e-9) | confirms the silent degradation the fix removes | + +**Reproduce:** +```bash +cd v2 && cargo test -p wifi-densepose-signal --no-default-features --lib \ + ruvsense::multistatic::tests::cir +# 3 passed (the 4th is #[cfg(not(debug_assertions))], add --release to run it) +``` + +**Resolution: FIXED** (not merely loud-fail-documented).

Guard re-derived against the bounded metric via named const `GHOST_TAP_CIRCULAR_VARIANCE_MAX = 0.99` (fires only when R̄ ≤ 0.01 — essentially uniform phase). The **threshold value is DATA-GATED**: a clean single-path ramp also sweeps the circle, so V alone can't separate clean from unsanitized without labelled frames — the default is deliberately conservative (strictly more permissive at the wrap boundary than the buggy linear guard). Fails-on-old: `phase_variance_circular_not_fooled_by_branch_cut` (old linear variance > TAU on wrap-straddling phases while circular V≈0, guard no longer trips), `phase_variance_circular_is_bounded_and_extremal`. | +| 2 | calibration.rs ~311 | `subtract_in_place` had a vacuous `if active_input {ki} else {ki}` branch implying a full-FFT→bin remap that didn't exist | P3 | **Resolved (M0 + M3 `df25a303e`).** Branch removed in M0 (sequential-convention documented).

The two voxel buffers (`x`, `gradient`; ~4 KB) are already allocated *once* per `reconstruct()` and `.fill`-reused across iterations — the per-solve alloc is a negligible fraction of the O(iters·links·voxels) inner product. Reusing scratch across *calls* would force `reconstruct(&self)`→`&mut self` (API break) for no measurable gain.

The "gain matrices" (`s:[f32;3]`, `k:[[f32;3];6]`) are fixed-size **stack** arrays, *not* heap — there is no per-update allocation to reuse; the compiler keeps them in registers/stack.

The real per-call eigendecomposition is in the `eigenvalue`-feature `estimate_occupancy` (`cov.eigh()` on a 56×56 covariance, an O(n³)≈175k-flop symmetric eigensolve + O(n²·frames) covariance build, run per call). The bench (`dsp_perf_bench`'s `eig` module) is committed, but `openblas-src` **fails to build on this Windows box** ("Non-vcpkg builds are not supported on Windows" — the very reason the project gate runs `--no-default-features`), so a measured µs number must come from a Linux/BLAS host; **not estimated/fabricated here.** Incremental SVD remains a sized future project, not a micro-fix. | +| 9 | coherence.rs / coherence_gate.rs | Z-score thresholds are magic constants, untested at boundaries | P1 | **RESOLVED-PARTIAL (`5193f6369`) — DATA-GATED.** De-magicked `classify_drift` (`DRIFT_STABLE_SCORE=0.85`, `DRIFT_STEP_CHANGE_MAX_STALE=10`) and the `coherence_gate.rs` defaults (`DEFAULT_ACCEPT_THRESHOLD`/`…REJECT…`/`…MAX_STALE_FRAMES`/`…PREDICT_ONLY_NOISE`) into named, documented consts marked EMPIRICAL DEFAULT; added at/just-below/just-above boundary tests (`classify_drift_*_boundary`) + `*_consts_unchanged_from_literals`. **Operating values explicitly NOT changed** — defensible values still need labelled stable/drifting traces. The gate already exposed these via `GatePolicyConfig` (config seam). | +| 10 | longitudinal.rs | Welford update not numerically guarded for n=0 | P1 | **RESOLVED (`4a9f2bcf4`) — MEASURED.** The shared `WelfordStats` (`field_model.rs`, consumed by longitudinal.rs) `count < 2` guards already prevent the n=0 NaN / n=1 div0 / `(count−1)` underflow, but the boundary was untested. Added `welford_finite_at_n0_and_n1` (finite + documented 0.0 sentinel at n=0/n=1). Fails-on-old proof: removing the `sample_variance` guard makes the test panic with "attempt to subtract with overflow" at the `(count − 1)` underflow. | +| 11 | cross_room.rs | Fingerprint hash collisions unhandled | P2 | Low collision prob; needs design. | +| 12 | gesture.rs | `euclidean_distance` no length-mismatch guard | P3 | **RESOLVED (M3 `adf9ed8e4`).** Added a `debug_assert_eq!` on the two slice lengths + a doc block stating the same-`feature_dim` caller contract and that `zip()` silently truncates on a mismatch. Behaviour-preserving (no-op in release, the operating path). Also de-magicked the confidence `1e-10` epsilon and pinned the DTW `n=0`/`m=0` boundary (`dtw_empty_sequence_is_infinite`). | +| 13 | adversarial.rs | Gini/consistency thresholds are magic constants | P1 | **RESOLVED-PARTIAL (`d672fa602`) — DATA-GATED.** Lifted the bare literals in `check`/`check_consistency` (`FIELD_MODEL_GINI_VIOLATION=0.8`, `ENERGY_RATIO_HIGH_VIOLATION=2.0`, `ENERGY_RATIO_LOW_VIOLATION=0.1`, `CONSISTENCY_ACTIVE_FRACTION_OF_MEAN=0.1`, `SCORE_W_*`) into named, documented consts marked EMPIRICAL DEFAULT; added at/just-below/just-above boundary tests (`energy_ratio_high_boundary`, `energy_ratio_low_boundary`, `field_model_gini_boundary`, `consistency_active_fraction_boundary`) + `tuning_consts_unchanged_from_literals`. **Operating values explicitly NOT changed** — defensible values still need labelled spoofed/clean CSI (Wi-Spoof, §6.2/§7.3). Bumping a const fails a boundary test (verified). | +| 14 | cir.rs | `fft_operator` path changes the witness hash (documented) — no test that it's *numerically close* to dense | P2 | **RESOLVED (`02e5dd13a`) — tolerance test added.** `fft_operator_within_tolerance_of_dense_canonical56` pins the **full `Cir` output** of the FFT path within a *documented* relative tolerance of the dense path on the production **canonical-56** config across τ ∈ {20,50,90} ns: every tap within `1e-2·|dominant|`, identical `dominant_tap_idx`, `active_tap_count`, `ranging_valid`, `dominant_tap_ratio` within `1e-2`, `rms_delay_spread` within `1e-2` rel. A regression that lets the FFT path drift (scaling/Φ-column bug) now fails here instead of silently corrupting a downstream witness. Extends the existing HT20/single-τ `fft_estimate_matches_dense_dominant_tap`. | +| 15 | multistatic.rs | `cir_gate_coherence` only estimates the **first** node/channel; multi-node CIR consensus unused | P2 | Design item (which node's CIR is authoritative?). | +| 16 | phase_align.rs | Iterative LO offset estimation has no convergence cap test | P2 | **RESOLVED (`02e5dd13a`) — cap test added.** `refinement_terminates_at_iteration_cap_when_not_converging` forces non-convergence (`tolerance = 0.0`, unreachable since `max_update ≥ 0`) and asserts the loop runs **exactly `max_iterations`** then returns — proving the cap (not convergence) bounds the loop, so a non-converging input can never spin forever. Companion `refinement_converges_before_cap_on_easy_input` proves the cap is an upper bound, not the only exit. Internal-only refactor: `estimate_phase_offsets` still returns the identical offset vector; a `…_counted` core surfaces the iteration count for the test. | +| 17 | hampel.rs | Window edge handling at series boundaries | P3 | **RESOLVED (M3 `19e0373c8`).** De-magicked the zero-MAD `1e-15` epsilon (`ZERO_MAD_EPSILON`), documented `hampel_filter`'s `# Errors`, and added the previously-untested `half_window == 0` error-path boundary (`test_zero_half_window_error`) + a zero-MAD constant-window characterization (`test_zero_mad_constant_window`). Window-edge handling itself is correct (`saturating_sub`/`.min(n)`); it is now pinned. | +| 18 | motion.rs | Threshold constants undocumented | P3 | **RESOLVED (M3 `c794d1a0c`).** Lifted the fusion weights, Doppler/variance/phase full-scale divisors, confidence-indicator weights, and adaptive-threshold clamp into named, documented EMPIRICAL-DEFAULT consts (`motion_tuning_consts_unchanged_from_literals` pins them) + small-`n` boundary tests (correlation `n<2`, temporal-variance `len<2`, adaptive-threshold history 9-vs-10, Doppler full-scale saturation). Doc-only-plus: values unchanged. | +| 19 | csi_ratio.rs | Division guard relies on `1e-12` epsilon; no test | P2 | **RESOLVED (`02e5dd13a`) — boundary test added.** Finding clarification: `csi_ratio.rs` implements the CSI *ratio model* as the **conjugate product** `H_i·conj(H_j)` (SpotFi/IndoTrack) — there is **no division**, hence no literal `1e-12` epsilon; the classic `H_i/H_j` ratio (which a `1e-12` guard protects) is deliberately avoided. `ratio_finite_at_and_below_1e_12_epsilon` pins the property the finding cares about: at and below the `1e-12` target magnitude (and at exact zero — where a division ratio is ±inf/NaN) the conjugate-product output is **finite**, exactly the conjugate product (bit-exact), collapses toward zero (the physically correct "no path" answer), and stays finite through `ratio_to_amplitude_phase`. | +| 20 | spectrogram.rs | `compute_multi_subcarrier_spectrogram` re-plans per subcarrier via `compute_spectrogram` | P2 | **MEASURED-HOT (`e839fa8f1`) — optimized, bit-identical.** Hoisted the FFT plan + window out of the per-subcarrier loop (new `compute_spectrogram_with_plan` core). **56-subcarrier** multi-spectrogram: **467.88 µs → 254.75 µs = 1.84×** (window 128); **627.27 µs → 448.39 µs = 1.40×** (window 256). The removed cost is the per-subcarrier `FftPlanner` re-plan (~1.86 µs/plan @ w128 × 56). Bit-identical (`multi_subcarrier_hoisted_plan_bit_identical`, `f64::to_bits` across all 4 windows × {power,magnitude}). The most likely real win predicted by the §7.4 intro — confirmed.

See CHANGELOG `[Unreleased] → Fixed`. + +--- + +## 8. Consequences + +- **Positive:** the ADR-134 CIR gate is alive for the first time in production; the adversarial detector can no longer be NaN-bypassed; three latent divide-by-zero NaN sources are gone; the per-frame PSD path and gesture DTW are measurably faster with bit-identical output; the SOTA landscape and a concrete LISTA-for-CIR roadmap are graded and recorded. +- **Negative / honest limits:** `canonical56()` models the canonical grid as a contiguous 56-tone band — a reasonable physical interpretation of a *resampled* grid, but not a literal hardware tone map; the CIR gate still uses only the first node's CIR (#15). The `phase_variance` **metric** is now correct (Mardia circular variance, Milestone-1 #1), so the branch-cut false-trip is gone — but its ghost-tap **threshold** (`GHOST_TAP_CIRCULAR_VARIANCE_MAX = 0.99`) is a conservative DATA-GATED default, not a calibrated operating point, and still awaits labelled sanitized/unsanitized frames to tune. Likewise the de-magicked coherence/adversarial thresholds (#9/#13) keep their pre-existing empirical values pending labelled calibration. +- **Neutral:** no public API removed; `with_cir_ht20()` kept (warned); files stay scoped; new bench is additive. diff --git a/docs/adr/ADR-155-nn-training-beyond-sota.md b/docs/adr/ADR-155-nn-training-beyond-sota.md new file mode 100644 index 0000000000..589662ee1f --- /dev/null +++ b/docs/adr/ADR-155-nn-training-beyond-sota.md @@ -0,0 +1,259 @@ +# ADR-155: NN / Training Beyond-SOTA Sweep — Milestone 1 (Claim Integrity, Honest Validation, the Unified Metric, and the SOTA Landscape) + +| Field | Value | +|-------|-------| +| **Status** | Proposed | +| **Date** | 2026-06-11 | +| **Deciders** | ruv | +| **Codebase target** | `wifi-densepose-train` (`metrics.rs`, `dataset.rs`, `proof.rs`, `rapid_adapt.rs`, `ruview_metrics.rs`, `config.rs`, `ablation.rs`, `subcarrier.rs`, `bin/train.rs`, `bin/verify_training.rs`), `wifi-densepose-nn` (`tensor.rs`, `translator.rs`, `onnx.rs`), benches, docs | +| **Relates to** | ADR-154 (Signal/DSP sweep, Milestone 0), ADR-152 (WiFi-Pose SOTA 2026 intake), ADR-150 (RF Foundation Encoder), ADR-079 (Camera-Supervised Pose), ADR-027 (MERIDIAN), ADR-024 (AETHER) | +| **Scope** | Milestone 1 of the beyond-SOTA NN/training sweep: the **integrity-critical** fixes that let the training/metrics subsystem substantiate a clean accuracy claim (the unified metric, leak-free validation, honest TTA, rigorous proof), a focused set of **correctness/security** fixes, two **measured** perf wins, the NN SOTA landscape with evidence grades, and a prioritized backlog. **~45 review findings are explicitly deferred (§8)** — nothing is silently dropped. | + +--- + +## 0.

The canonical-metric *logic* is therefore validated two ways: (1) the non-tch reachable surface (`compute_pck`/`compute_oks` free functions, `dataset.rs` split, `rapid_adapt.rs`, `ruview_metrics.rs`) runs under the workspace test suite with new regression tests; (2) the `tch`-gated accumulator/trainer/proof changes are routed through those same canonical functions, so the metric definition is identical whether or not tch is present.

Decision — TIER 1: CLAIM INTEGRITY (the "prove everything" core) + +### 2.1 Unify the metrics — ONE canonical definition — ACCEPTED & IMPLEMENTED + +There is now exactly **one** PCK and one OKS that may be used for any *reported* number, in the `canonical` region of `metrics.rs`: + +- **`pck_canonical(pred, gt, vis, k)` — torso-normalized PCK@k.** A keypoint `j` is correct iff `‖pred_j − gt_j‖₂ ≤ k · torso`, where `torso = ‖left_hip(11) − right_hip(12)‖₂` in the keypoint coordinate space, with a **bounding-box-diagonal fallback** when the hips are not both visible. This is the COCO / ADR-152 convention validated in `benchmarks/wiflow-std/RESULTS.md` (the ~96% PCK@20 reproduction — hip↔hip torso, COCO Setting). **Zero visible joints ⇒ `(0, 0, 0.0)`** — a sample with no measurable evidence scores 0, never 1. +- **`oks_canonical(pred, gt, vis)` — COCO OKS.** `s = sqrt(area)` is derived from the **GT pose extent** (the canonical torso size as a robust, always-positive scale proxy), never a fixed `1.0`. There is no escape hatch that makes OKS ≈ 1.0 for any pose; a degenerate (zero-extent) pose returns 0.0. + +**Single source of truth, enforced.** `MetricsAccumulator::update` (the trainer's), `compute_pck`, `compute_per_joint_pck`, `compute_oks`, `aggregate_metrics`, and the deprecated `compute_pck_v2`/`compute_oks_v2`/`MetricsAccumulatorV2` **all route through** `pck_canonical`/`oks_canonical`. So `Trainer::evaluate()` → `MetricsAccumulator` → canonical; the WiFlow-STD bench definition (RESULTS.md) is the reference the canonical *matches*. `eval.rs` reports MPJPE (a distinct, non-divergent error metric, unchanged). The `v2` functions and the `training_bench.rs` raw-threshold kernel are annotated **`#[deprecated]` / "DO NOT USE for reported metrics"**. + +**The two claim-inflating bugs are fixed and pinned by regression tests:** + +- `canonical_pck_zero_visible_is_zero_not_one` — no-visible ⇒ PCK 0.0 (was 1.0). +- `canonical_oks_not_one_for_wrong_pose_on_normalized_coords` — a pose off by 3× the torso on `[0,1]` coords yields OKS < 0.2 (the old `s=1.0` path returned ≈1.0). +- `canonical_pck_uses_hip_to_hip_torso`, `canonical_torso_falls_back_to_bbox_when_hips_hidden` — pin the normalizer. +- `all_invisible_gives_zero_pck` (renamed from `all_invisible_gives_trivial_pck`, comment cites this ADR) — the trainer accumulator now scores no-visible as 0. + +**Legitimately changed test expectations** (each updated with a comment citing this finding): the historical "perfect on an all-coincident pose" fixtures used keypoints at a single point, which is *correctly unscoreable* under canonical (zero extent ⇒ no scale). Test fixtures were given a real ±0.05 hip span so the canonical normalizer is positive; `all_invisible_*` flipped from 1.0 → 0.0. + +### 2.2 Honest validation — leak-free split + synthetic-val disclosure — ACCEPTED & IMPLEMENTED + +**The leak.** MM-Fi windows are extracted with **stride 1** (`MmFiEntry::num_windows = num_frames − window_frames + 1`), so adjacent windows overlap by `window_frames − 1` frames (~99% at the default 100-frame window). And `bin/train.rs` validated a *real* MM-Fi training run against a **synthetic** val set "for pipeline verification" — any PCK it printed was meaningless on two counts. + +**The fix (mirroring the leak-free discipline of `occupancy_bench::EvalSplit`):** + +- `MmFiDataset::subject_disjoint_split(test_subject_fraction, seed) → (train_view, test_view)` partitions **whole subjects** to one side. Because every window of a subject travels with that subject, the two views share **no subject and no window** — leak-free by construction, deterministic per seed. Returns `DatasetError::InvalidSplit` on <2 subjects, bad fraction, or an empty side. +- `assert_split_leak_free(train, test)` independently verifies subject-disjointness **and** window-index-disjointness, and is called inside the split so a leaky split can never be handed out. +- `bin/train.rs` now **prefers the real split**; the synthetic path is reachable only as a labelled fallback (single-subject data) and is routed through a new `run_smoke_test` that prefixes every metric `[SMOKE-TEST] (DO NOT REPORT)`. `--dry-run` is likewise relabelled. A synthetic-val PCK can no longer be mistaken for a measurement. + +**Leak-free proof (tests):** `subject_split_is_subject_and_window_disjoint` (no shared subject, no shared window index, partition covers every window once), `subject_split_is_deterministic_for_seed`, `subject_split_rejects_single_subject`, `subject_split_rejects_bad_fraction`, `assert_leak_free_detects_injected_subject_leak` (the validator catches a deliberately-injected subject overlap — a guard against future partitioner bugs). + +### 2.3 rapid_adapt honesty — real gradients, scoped claim — ACCEPTED & IMPLEMENTED + +`rapid_adapt.rs`'s `contrastive_step`/`entropy_step` wrote a **fake gradient** (`grad += v * 0.01`) unrelated to the stated triplet / entropy objective — so any "TTA improves the metric" was unsupported by the code. + +**Resolution: real gradients (not removal).** The two `*_loss` functions are now **pure evaluators** of the real objective; `RapidAdaptation::adapt` descends them with a **central finite-difference gradient** of that exact loss (`∂L/∂wᵢ ≈ (L(w+εeᵢ) − L(w−εeᵢ))/2ε`). Finite differences genuinely minimize the stated objective (to O(ε²) truncation), so "the adaptation loss decreases" is now a **real, reproducible** measurement rather than an artefact of a hand-tuned step. The returned `final_loss` is the *actual* objective at the produced weights. + +**Honest scope caveat (recorded in the module and here):** this minimizes a *self-supervised proxy* (temporal-contrastive + prediction entropy) over a tiny LoRA bottleneck on raw CSI. It is **NOT** wired to the pose model, and **there is no measured end-to-end PCK gain on WiFi pose from this path.** TTA-on-pose is a future, **not-yet-measured** capability — no PCK improvement may be cited from this module. + +**Tests:** `contrastive_loss_decreases` and `entropy_loss_decreases` (20/30 real gradient steps do not increase the loss vs 0 steps), `reported_loss_is_the_real_objective_not_a_placeholder` (the returned `final_loss` equals an independent recomputation of the objective at the output weights — i.e. it is the real loss, not a fabricated number). + +### 2.4 proof.rs rigor — margin + committed-hash requirement — ACCEPTED & IMPLEMENTED + +The deterministic proof self-certified: `generate_expected_hash` blessed whatever the pipeline emitted, PASS counted *any* loss decrease (including 1e-9 float noise), and a *missing* expected hash defaulted to PASS. + +**Two hardenings:** + +1. **Minimum-decrease margin.** `MIN_LOSS_DECREASE = 1e-4`. A run counts as "learning" only when `initial − final ≥ MIN_LOSS_DECREASE` — well above float noise, far below a real step's decrease. A pipeline that only wanders by noise now **FAILS**. +2. **No-hash is a SKIP, never a PASS.** `ProofResult::is_pass()` requires `hash_matches == Some(true)` (a *committed* `expected_proof.sha256`). An absent baseline yields SKIP (exit 2). The `verify-training` binary additionally **fails fast** on a sub-margin loss *before* the hash comparison, so a missing baseline can never downgrade a non-learning pipeline to SKIP. + +**What this proves — and what it does NOT (disclosed):** the proof certifies **reproducibility and determinism** (same seed ⇒ same weights ⇒ same hash) and that the optimiser *measurably* reduces a loss. It runs on a deterministic *synthetic* dataset by construction, so it does **not** prove the shipped weights came from real MM-Fi data, nor that any accuracy claim is met. Accuracy is substantiated separately (`benchmarks/wiflow-std/RESULTS.md`). There is currently **no committed `expected_proof.sha256` for the Rust proof**, so it is honestly in the SKIP state until a baseline is committed on a libtorch-enabled host — and SKIP is now reported as SKIP, not green. + +**Tests:** `no_committed_hash_is_skip_not_pass`, `submargin_loss_change_fails_even_without_hash`, `committed_matching_hash_with_real_decrease_passes`. + +--- + +## 3.

The intended fix was a read-lock. **It is not landable on `ort 2.0.0-rc.11`:** the safe `Session::run` is `&mut self` (verified against the vendored source) — there is no `&self` run path, so a read-lock fails the borrow checker. The underlying C++ `OrtSession::Run` is thread-safe, but exploiting that would require an `unsafe` interior-mutability bypass; we did **not** introduce that soundness risk. The write lock was kept, with a doc comment recording the upgrade path (a future `ort` with `&self` run ⇒ flip to `read()`). + +- **Harness landed anyway**, empirically proving the serialization: `cargo bench -p wifi-densepose-nn --no-default-features --features onnx --bench onnx_bench -- onnx_concurrency` → throughput **drops** with more threads (1 thr 19.4 Kelem/s → 2 thr 16.9K → 4 thr 14.0K → 8 thr 14.3K).

This is a finding, not a failure — recorded here rather than hidden. + +**Goal B (`test_metrics.rs`) — RESOLVED, MEASURED.** The canonical core (`pck_canonical`/`oks_canonical`/`canonical_torso_size`/sigmas/`bounding_box_diagonal`) was hoisted into a new **un-gated** `metrics_core` module (the full `metrics` module is `tch-backend`-gated, so the canonical definition was previously unreachable from the workspace test gate; `metrics` now re-exports it → still ONE implementation). `tests/test_metrics.rs` now asserts the **production** functions against hand-computed fixtures — `canonical_pck_matches_hand_computed_fixture` (3/4 correct ⇒ 0.75, hand-derived), zero-visible⇒0.0, hip↔hip normalizer pin, OKS perfect⇒1.0, the fake-Gold pin — plus `test_kernel_agrees_with_canonical`, a differential test where an independent raw-threshold reference must AGREE with canonical in the torso=1.0 regime. (10→12 tests.) + +**Goal C (`training_api.rs` PCK) — RESOLVED by RELABEL, MEASURED.** Torso-height is **load-bearing** (pixel-space, vertical nose→hip scale, `[17×3]` layout, no `ndarray`/train dep), so unifying would silently change the live numbers' meaning — exactly what to avoid. Resolution: relabel everywhere the metric surfaces so it is never read as canonical, in both the named `training_api.rs` (now `compute_pck_torso_height`, struct/JSON-field docs, `pck_torso_h@0.2` logs) **and** — the real fix — the LIVE `trainer.rs` path (`pck_at_threshold` documented raw-unnormalized; `oks_map` `area=1.0` flagged fake-Gold; `main.rs` prints `pck_raw@0.2` / `oks_map(area=1.0 proxy)`). No wire-format field or `pub`-fn renames (no silent API break). Pinned by `torso_pck_is_labelled_distinctly_from_canonical` (training_api) and `pck_at_threshold_is_raw_unnormalized_not_canonical` (the live kernel). True unification (route the live server through `pck_canonical`/`oks_canonical`) remains a deferred §8 item — it needs a torso scale on the live data and the train crate as a dep. + +--- + +## 9. Consequences + +**Positive.** The training/metrics subsystem can now substantiate a clean accuracy claim: one documented metric used everywhere, a leak-free split, an honest TTA path, a proof that fails on noise and refuses to bless an unbaselined run, and two of the most claim-inflating bugs (false-perfect PCK, fake-Gold OKS) closed and pinned by regression tests. The unmeasured/unprovable parts are **disclosed**, not hidden. + +**Negative / honest.** The reportable-metric tch-gated code cannot be compiled on the dev host (libtorch absent), so its validation rests on routing through the workspace-tested canonical functions plus review; the Rust deterministic proof is in SKIP until a baseline is committed on a tch host; the ONNX concurrency win is blocked upstream; and ~45 findings are deferred. None of these is presented as done. + +**Picture changed by Milestone-1b (§8.1) — corrected, not hidden.** The §1 "seven divergent metrics" count was an **under-count**. The metric-unification audit (Goal A) found the live `wifi-densepose-sensing-server` carries additional, divergent definitions the §1 table omitted: a **raw, unnormalized** `pck_at_threshold` and an **`area=1.0` fake-Gold** `oks_map` in `trainer.rs` — and these, not the orphaned `training_api.rs` the backlog named, are what actually drive the live-reported `best_pck`/`best_oks`. Milestone-1b **relabelled** them (load-bearing math on different data; relabel beats false unification) and pinned the divergence with tests; full unification onto the canonical definition stays deferred. So the canonical *train/nn* metric is unified and test-validated end-to-end, but the *sensing-server* still computes (now clearly-labelled, non-canonical) progress proxies — disclosed here as the honest current state. diff --git a/docs/adr/ADR-156-ruvector-fusion-beyond-sota.md b/docs/adr/ADR-156-ruvector-fusion-beyond-sota.md new file mode 100644 index 0000000000..95493d30a5 --- /dev/null +++ b/docs/adr/ADR-156-ruvector-fusion-beyond-sota.md @@ -0,0 +1,265 @@ +# ADR-156: RuVector / Cross-Viewpoint Fusion Beyond-SOTA Sweep — Milestone 2 (Correctness Integrity, an Honest GDOP, Crafted-Input Safety, a Measured Hot-Path Win, and the ANN/Fusion SOTA Landscape) + +| Field | Value | +|-------|-------| +| **Status** | Proposed | +| **Date** | 2026-06-11 | +| **Deciders** | ruv | +| **Codebase target** | `wifi-densepose-ruvector` — `viewpoint/` (`attention.rs`, `geometry.rs`, `fusion.rs`, `coherence.rs`), `mat/` (`triangulation.rs`, `heartbeat.rs`), `sketch.rs`, benches, docs | +| **Relates to** | ADR-031 (RuView sensing-first RF mode), ADR-016/017 (RuVector integration), ADR-024 (AETHER re-ID), ADR-027 (MERIDIAN cross-env), ADR-084 (RaBitQ similarity sensor), ADR-138 (ClockQualityGate), ADR-152 (WiFi-Pose SOTA 2026 intake), ADR-154 (Signal/DSP sweep M0), ADR-155 (NN/Training sweep M1) | +| **Scope** | Milestone 2 of the beyond-SOTA sweep: four **correctness/integrity/security** fixes on the cross-viewpoint fusion path (each pinned by a regression test that fails on the old code), one **measured** hot-path perf win + a new criterion bench, the ANN/fusion SOTA landscape graded MEASURED/CLAIMED/data-gated, and a prioritized deferred backlog. **Nothing is silently dropped.** | + +--- + +## 0. PROOF discipline (this ADR's contract) + +This project has been publicly accused of "AI slop." Milestone 2 answers with **evidence, not adjectives** — the same contract as ADR-154/155: + +- Every correctness/integrity fix ships a **committed regression test that fails on the old code and passes on the new**. We verified each by reverting the fix and observing the test fail (recorded in §6). +- Every perf number is **MEASURED before/after** with the exact reproduce command and a committed criterion bench. A perf claim without a measured before/after is **UNPROVEN** and is not made here. +- Every external SOTA reference is graded **MEASURED** / **CLAIMED** / **DATA-GATED**, distinguishing what a paper *measured* from what it *asserts* from what our own prior measurement (ADR-152) says is **not currently the bottleneck**. +- We disclose, in full, the **one staged finding that turned out to be a numeric no-op** (§2.1): the geometric-bias "angular wrap bug" is real as a *contract* violation but, because the bias kernel is `cos()` (even and 2π-periodic), it changes **no output value** under the current kernel. We land the fix anyway (it matches the documented contract and reuses the canonical helper) but we **do not claim a behaviour change** — that would be exactly the kind of inflation this sweep exists to prevent. + +Test machine for the perf numbers: Windows 11, `cargo bench --release`, criterion 0.5. Numbers are wall-clock medians on this box; the **ratio** (before/after) is the claim, not the absolute ns. + +Build/test gate: `cargo test --workspace --no-default-features` (the project's standard gate — no `crv`/GPU features). All fixes in this milestone are on the **default, non-feature-gated surface**, so they are fully exercised by the standard gate. + +--- + +## 1. Context + +The cross-viewpoint fusion stack (`viewpoint/` — ADR-031) combines per-viewpoint AETHER embeddings into one fused embedding via geometric-bias attention, gated by phase coherence, with array-geometry quality scored by a Geometric Diversity Index and a Cramér-Rao bound. The `mat/` survivor-localisation helpers (`triangulation.rs`, `heartbeat.rs`) share the same crate. A beyond-SOTA review surfaced findings spanning a **mislabeled metric**, an **angular-distance contract violation**, **crafted-input panics on a network-reachable path**, and a **redundant clone in the fusion hot path**, plus an ANN/fusion SOTA-research gap. Milestone 2 closes the provable subset and grades the research landscape. + +--- + +## 2. Decision — CORRECTNESS / INTEGRITY FIXES + +Each fix ships a regression test (all on the non-feature-gated, workspace-tested surface). + +### 2.1 GeometricBias angular separation — use the canonical *wrapped* distance — ACCEPTED & IMPLEMENTED (honest: numeric no-op under the current cos kernel) + +**The finding.** `attention::GeometricBias::build_matrix` computed the pairwise angular separation as the **raw** `|azimuth_i − azimuth_j|`. That can exceed π and mis-states the separation across the 0/2π seam (350° and 10° are 20° apart, but raw `|Δ|` = 340°). The module already had a correct wrapped helper, `geometry::angular_distance` (returns `[0, π]`), but it was **private** and `GeometricBias` did not use it. + +**The honest correction (disclosed, not hidden).** The bias kernel is `w_angle·cos(theta_ij)`. Because `cos` is **even and 2π-periodic**, `cos(raw) == cos(wrapped)` for every pair (verified numerically: max abs diff `1.1e-16` across seam-crossing test cases). So under the *current* kernel this "bug" produces **identical bias values** — it is a **contract violation, not a behaviour bug**. We say so plainly rather than dressing a no-op as a fix. + +**Why land it anyway.** (1) It makes the code satisfy its own documented contract (`theta_ij`: "angular separation in radians", which must be `[0, π]`). (2) It reuses the **single canonical** `angular_distance` helper (now made `pub`), eliminating a divergent angle computation — the same single-source-of-truth discipline ADR-155 applied to metrics. (3) It is **correct by construction** for any future non-even angular kernel (e.g. a linear `w_angle·theta_ij` penalty), which the raw-diff form would silently break. + +**Tests:** `geometric_bias_angular_separation_uses_wrapped_distance` (pins that a seam-crossing pair's wrapped distance is 20° while its raw `|Δ|` exceeds π, and that `build_matrix` is symmetric across the seam) and `geometric_bias_linear_angular_kernel_would_catch_raw_diff` (pins the wrapped value ∈ `[0, π]` — the invariant a future linear kernel relies on; the raw-diff form gives 190° where the wrapped form gives 170°). + +### 2.2 Crafted-input panics on the fusion/localisation path — typed `None` instead of panic — ACCEPTED & IMPLEMENTED (the security item) + +**The finding (DoS).** Two functions on a path that can carry **network-sourced multistatic frames** panicked on crafted input: + +- `mat::triangulation::solve_triangulation` indexed `ap_positions[0]` (panics on an empty AP table) and `ap_positions[i]` / `ap_positions[j]` (panics when a TDoA measurement references an **out-of-range AP index**). A remote peer supplying a TDoA tuple `(i=99, …)` with only 3 APs triggers an out-of-bounds panic — a remotely-triggerable denial of service. +- `mat::heartbeat::CompressedHeartbeatSpectrogram::band_power` computed `self.n_freq_bins - 1`, which **underflows** (usize `0 − 1`) for a zero-bin spectrogram — a debug panic / release `usize::MAX` (then an out-of-range index). + +**The fix.** `solve_triangulation` uses `ap_positions.first()?` and `ap_positions.get(i)?` / `.get(j)?` — any empty table or out-of-range index returns `None`, never panics. `band_power` guards `n_freq_bins == 0` up front and **clamps both bounds** into `[0, last]`, returning `0.0` for empty/inverted ranges. No out-of-range index, no subtraction overflow, on any input. + +**Tests:** `triangulation_out_of_range_index_returns_none_no_panic`, `triangulation_empty_ap_positions_returns_none_no_panic`, `heartbeat_band_power_zero_bins_no_panic`, `heartbeat_band_power_out_of_range_bounds_no_panic`. Each **panics on the old code** (verified by reverting — §6) and returns a clean `None`/`0.0` on the new. + +### 2.3 GDOP mislabel — compute a real, dimensionless GDOP — ACCEPTED & IMPLEMENTED + +**The finding.** `geometry::CramerRaoBound` exposed a field named `gdop` ("Geometric Dilution of Precision") that was computed as `(crb_x + crb_y).sqrt()` — **identical to `rmse_lower_bound`**. That is the RMSE (metres, noise-dependent), **not** a GDOP. GDOP is a *dimensionless geometry factor* independent of the noise level; the name was a lie about the quantity. + +**The fix (honest rename was the fallback; real GDOP was cheap, so we computed it).** True GDOP `= sqrt(trace(G⁻¹))` where `G` is the **unit-variance** bearing-geometry matrix (the Fisher matrix with every `1/σ²` set to 1). It depends only on the array/target geometry and relates noise to position error as `rmse ≈ GDOP·σ`. We accumulate `G` alongside the FIM in both `estimate` and `estimate_regularised` (cheap 2×2), and report `INFINITY` (not NaN/panic) for a degenerate collinear geometry. The doc comment now states exactly what the field is and what it used to (wrongly) be. + +**Test:** `gdop_is_dimensionless_and_noise_independent` — scales every sensor's noise by 10× and asserts GDOP is unchanged while RMSE scales ~10×, and that `rmse ≈ GDOP·σ` at both noise levels. The old `gdop = sqrt(crb_x + crb_y)` **fails** this (it scaled with noise, proving it was RMSE) — verified by reverting (§6). + +### 2.4 `fuse()` double-clone in the aggregation hot path — eliminate the redundant clone — ACCEPTED & IMPLEMENTED (MEASURED — §4) + +**The finding.** `MultistaticArray::fuse` (and `fuse_ungated`) cloned every viewpoint embedding **twice** per fusion: once into the `extracted` tuple vector (`v.embedding.clone()`), then **again** when building the attention input (`extracted.iter().map(|(_, e, _, _)| e.clone())`). At the AETHER dimension (128 f32 = 512 B) over up to 8 viewpoints, that is a wholly redundant second heap allocation + memcpy per viewpoint, every TDM cycle. + +**The fix.** Build `extracted` once (the unavoidable clone out of the borrowed `self.viewpoints`), then **consume** `extracted` by value and **move** each embedding into the attention input (`embeddings.push(emb)`), capturing geometry/ids by `Copy` in the same pass. One clone per viewpoint instead of two. Measured win in §4. + +--- + +## 3. Security review (touched files) + +The §2.2 crafted-input panics **are** the security item: a DoS via out-of-range indices / zero-bin underflow on a fusion/localisation path that may be driven by network-sourced multistatic frames. Beyond those, the touched files were swept for further panic-on-untrusted-input / unbounded-alloc sites: + +- `attention.rs` — all indexing is over internally-sized `n × n` / `d` loops bounded by validated input lengths (`DimensionMismatch` is returned for ragged embeddings); softmax denominators are floored with `f32::EPSILON`. No unbounded alloc (sizes derive from caller-supplied vector lengths already validated against `d_in`). **No further action.** +- `geometry.rs` — `det`/`det_g` are floored before division; degenerate geometry yields `None`/`INFINITY`, never NaN-panic. **No further action.** +- `fusion.rs` — embedding dimension is validated in `submit_viewpoint`; the event log is bounded (`max_events`, oldest-half drain). **No further action.** +- `coherence.rs` — circular buffer is fixed-capacity; gate thresholds are clamped. **No further action.** + +No `unsafe`, no `unwrap()` on external input, and no unbounded allocation remain on the touched paths after §2.2. + +--- + +## 4. MEASURED perf win (new criterion bench) + +A new bench, `crates/wifi-densepose-ruvector/benches/fusion_bench.rs`, covers the fusion hot path. It has two groups: `fusion_pipeline` (end-to-end `MultistaticArray::fuse_ungated()` at 2/4/8 viewpoints, dim 128) and an isolated A/B of the §2.4 marshalling step (`embedding_extract/before_double_clone` vs `after_single_clone`). + +- **Reproduce:** `cargo bench -p wifi-densepose-ruvector --bench fusion_bench` +- **Measured (`embedding_extract`, 8 viewpoints × 128-d), medians:** `before_double_clone` **1.0029 µs** → `after_single_clone` **461.6 ns** — **~2.17× faster** on the marshalling step. The result is what theory predicts (two embedding clones collapse to one), confirming the redundant clone was the cost, not noise. +- **End-to-end `fusion_pipeline` (medians):** 2 vp = 56.3 µs, 4 vp = 99.5 µs, 8 vp = 202.1 µs. The marshalling (~0.5–1 µs) is **well under 1%** of total fusion cost (dominated by the `n×n` attention), so the **end-to-end** effect is modest by construction; the `embedding_extract` A/B isolates and proves the clone-elimination itself. We report this honestly rather than attributing the full 2.17× to the pipeline. + +The double-clone elimination is also correctness-neutral: all 100 `viewpoint`/`mat` lib tests pass unchanged. + +--- + +## 5. The ANN / cross-viewpoint-fusion SOTA landscape (graded) + +| # | Candidate | What | Grade | Verdict | +|---|-----------|------|-------|---------| +| **1** | **SymphonyQG** (SIGMOD 2025, public code) | Unified quantization + graph ANN; source reports **3.5–17× QPS over HNSW at equal recall**, pure-CPU / edge-portable. | **MEASURED-direction-tested** (was CLAIMED) — **[ADR-261](ADR-261-ruvector-graph-ann-index.md)** built the missing HNSW baseline + a SymphonyQG-style 1-bit quantized-traversal variant and **measured** the ratio on our hardware. | **DONE — direction REFUTED at our scale (honest negative).** ADR-261 built the real HNSW baseline (**~25× QPS over linear scan at recall ≥0.99**, the substrate this row wanted) and a quantized variant. At N=10k the 1-bit Hamming traversal is **too coarse** — its best recall is 0.738, never reaching the ≥0.90 equal-recall point, so **no QPS win over float HNSW** (the SymphonyQG 3.5–17× is *not* reproduced by our 1-bit construction here). Caveat: **our HNSW + our 1-bit quant, not SymphonyQG's system**; expected crossover at large N + a multi-bit code. We did **not** tune to manufacture a speedup. | +| **2** | **Multi-bit / Extended RaBitQ + unbiased estimator** | Extends our existing **1-bit** `sketch.rs` (ADR-084): Pass-2 rotation, multi-bit Pass-3, and the **real RaBitQ unbiased distance estimator** (Gao & Long SIGMOD 2024) reranking the candidate set from the 1-bit code + 8 B/vec side info (§11). | **MEASURED-on-our-hardware** (was CLAIMED) — rotation (§10), multi-bit (§10), and the estimator (§11) all implemented + benchmarked. Rotation lifts strict-K 36%→46%; multi-bit (≤4-bit) reaches 74% strict; **the estimator reaches 49.71% strict (cosine rerank), still short of 90%.** All clear 90% only with over-fetch (estimator improves the factor: 95% at candidate_k=24 vs sign 91.6%). | **DONE — RESOLVED-PARTIAL / NEGATIVE.** Rotation (§10) + estimator (§11) built and MEASURED. The honest negative (no strict-bar 90% from rotation, ≤4-bit, **or the unbiased estimator**) is recorded, not hidden. Over-fetch + Pass-2 is the path that meets the bar (ADR-084's "candidate set" pattern); the estimator lowers the over-fetch factor needed. | +| **3** | **GraphPose-Fi-style learned antenna-attention + ChebGConv fusion head** | Would replace the current **untrained identity-projection + mean-pool** "attention" (the `CrossViewpointAttention` default is `ProjectionWeights::identity` — not a *learned* attention) with a learned graph fusion head. | **DATA-GATED** (per ADR-152 measurement (b): architecture is **NOT** the current bottleneck — **data is**) | **ACCEPTED-future, data-gated. Do NOT build now.** ADR-152's measured lesson was that swapping architecture without more/better paired data does not move PCK. Building a learned fusion head before the data exists would repeat the mistake ADR-155 §5 also flagged for GraphPose-Fi. | +| — | **Cramér-Rao / sensor-placement** (`geometry.rs` CRB) | Investigated for a 2026 advance beating the textbook Fisher-information CRB already implemented. | **Investigated — NO ACTION** | **Cleared honestly.** No 2026 method beats the closed-form Fisher-information CRB for this 2-D bearing problem; our implementation is already correct SOTA. (Recording a negative result is a deliberate anti-slop signal.) The only CRB change this milestone is the §2.3 *GDOP* honesty fix, which is a labelling/quantity correction, not an algorithmic one. | + +--- + +## 6. Validation + +- **Bug-catching tests verified to bite.** Each §2.2/§2.3/§2.4-adjacent fix was reverted and the corresponding test observed to **fail on the old code**, then restored: + - `triangulation_out_of_range_index_returns_none_no_panic` / `triangulation_empty_ap_positions_returns_none_no_panic` — **panic** (index out of bounds) on old code. + - `heartbeat_band_power_zero_bins_no_panic` — **panic** ("attempt to subtract with overflow") on old code. + - `gdop_is_dimensionless_and_noise_independent` — **assertion failure** (GDOP scaled with noise) on old code. + - §2.1 (angular wrap) is the **disclosed no-op**: its tests pin the *contract* (wrapped value ∈ `[0, π]`), since the cos kernel makes the bias value numerically identical with or without the fix. We do not claim a behaviour change. +- **`cd v2 && cargo test -p wifi-densepose-ruvector --no-default-features --lib`** — **100 passed / 0 failed** (was 93; +7 new tests). +- **`cd v2 && cargo test --workspace --no-default-features`** — **3050 passed / 0 failed** (full-workspace aggregate across all crates and test binaries; the +7 new `wifi-densepose-ruvector` tests are included and green). +- **`python archive/v1/data/proof/verify.py`** — **`VERDICT: PASS`** (the Python pipeline proof is independent of these Rust changes — confirmed unaffected). +- New `fusion_bench` compiles and runs under the default feature set. + +--- + +## 7. What changed, file by file + +- `viewpoint/geometry.rs` — `angular_distance` made `pub` (single canonical wrapped-angle helper); real dimensionless GDOP (`sqrt(trace(G⁻¹))`) in `estimate`/`estimate_regularised` (was RMSE mislabelled); `gdop` doc states the quantity and the prior bug; `gdop_is_dimensionless_and_noise_independent` test. +- `viewpoint/attention.rs` — `GeometricBias::build_matrix` uses the canonical wrapped `angular_distance` (contract fix; numeric no-op under cos — disclosed); two contract-pinning tests. +- `viewpoint/fusion.rs` — `fuse`/`fuse_ungated` move embeddings out of `extracted` (single clone, not double); existing tests unchanged and green. +- `mat/triangulation.rs` — `first()?` / `get(i)?` / `get(j)?` guards (no panic on empty table / crafted indices); two no-panic tests. +- `mat/heartbeat.rs` — `band_power` zero-bin guard + bounds clamp (no underflow / out-of-range index); two no-panic tests. +- `benches/fusion_bench.rs` (new) + `Cargo.toml` `[[bench]]` — fusion hot-path bench + the double-clone A/B. + +--- + +## 8. Deferred backlog (NOT silently dropped) + +The review surfaced more than this milestone scoped. Tracked here for a future ADR-156 milestone: + +- **SymphonyQG reproduction** (§5 #1) — **RESOLVED-DIRECTION-TESTED** (see [ADR-261](ADR-261-ruvector-graph-ann-index.md)). The missing HNSW baseline + a SymphonyQG-style 1-bit quantized-traversal variant were built and **MEASURED**: float HNSW is ~25× over linear scan at recall ≥0.99 (the baseline this gap needed), but our 1-bit quantized traversal is **too coarse to beat float HNSW at equal recall at N=10k** (best recall 0.738) — the 3.5–17× is **not reproduced** by our construction. Honest negative recorded; expected crossover is large N + a multi-bit traversal code. (Caveat: our HNSW + our 1-bit quant, not SymphonyQG's exact system.) +- **Multi-bit / Extended RaBitQ** (§5 #2) — **RESOLVED-PARTIAL** (see §10). Pass-2 randomized rotation (FHT + seeded ±1 sign flips, `src/rotation.rs`) and a multi-bit Pass-3 experiment landed and were MEASURED against the ADR-084 ≥90% bar. **Honest result: rotation helps (+10pp at the strict bar) and Pass-2 reaches 90% with ~3× over-fetch, but NEITHER rotation nor multi-bit (up to 4-bit) clears the strict candidate_k==K 90% bar on the tested anisotropic distribution.** The original `1-bit sign quantization ships first; rotation/more-bits later if benchmark-measured top-K coverage drops below 90%` deferral is therefore retired: the rotation is built, the bar is characterised, and the residual gap is documented rather than deferred. +- **Learned cross-viewpoint fusion head** (§5 #3, GraphPose-Fi-style) — **data-gated**: blocked on the paired multi-room data ADR-152 measurement (b) identified as the real bottleneck; do not build the architecture first. +- **`CrossViewpointAttention` learned projections** — the default `ProjectionWeights::identity` + mean-pool is honest but unlearned; wiring real learned Q/K/V projections is part of the data-gated item above (no learned weights ⇒ the "attention" is currently a geometric-bias-weighted average, which the code/docs should keep stating plainly). +- **`coherence.rs` / `fusion.rs` micro-opts and the remaining lower-severity review findings** (style, doc, further hot-path tuning) from the fusion gap review. + +--- + +## 9. Consequences + +**Positive.** The fusion path now: uses one canonical wrapped angular-distance helper; reports a **real** dimensionless GDOP instead of a mislabeled RMSE; cannot be panicked by crafted multistatic indices or a zero-bin spectrogram (DoS closed); and does one embedding clone per viewpoint instead of two (measured). Every fix is pinned by a test that fails on the old code, and the ANN/fusion SOTA landscape is graded so the near-term (multi-bit RaBitQ) and the data-gated (learned fusion) are not confused. + +**Negative / honest.** The headline angular-wrap fix is a **numeric no-op** under the current cos kernel — we land it for contract/maintainability, not because it changes an output, and we say so. The two strongest external candidates (SymphonyQG, learned fusion) are **not built here** — one is CLAIMED-pending-reproduction, the other is data-gated by a prior measurement. The perf win is a **local hot-path** improvement, modest in the end-to-end pipeline (attention dominates). None of these is presented as more than it is. + +--- + +## 10. RaBitQ Pass-2 / multi-bit — IMPLEMENTED & MEASURED (§8 backlog item #2) + +Milestone-1 of the §8 backlog. Status: **RESOLVED-PARTIAL** — built, measured, honest negative on the strict bar. + +### 10.1 What landed + +- **`crates/wifi-densepose-ruvector/src/rotation.rs`** (new) — `Rotation`, a deterministic randomized orthogonal rotation `R = H·D`: a **Fast Hadamard Transform** (`O(d log d)`, in-place butterfly, `1/√m` normalized so it is norm-preserving) composed with a diagonal of **seeded ±1 sign flips** (SplitMix64 from a stored `u64` seed). Chosen over a dense `d×d` matrix because that is `O(d²)` memory/time and infeasible at the 65,535-d the wire format provisions for; FHT is the standard fast-orthogonal (randomized-Hadamard / fast-JL) construction. Non-power-of-two `d` zero-pads to `next_pow2(d)` and reads back the first `d` coords. +- **`sketch.rs`** — additive Pass-2 API: `Sketch::from_embedding_rotated`, `SketchBank::with_rotation` + `insert_embedding` / `topk_embedding` / `novelty_embedding`. **Pass 1 (`from_embedding`) is byte-for-byte unchanged**; a Pass-2 sketch has identical `embedding_dim` / packed-byte length / wire shape, so `WireSketch` and existing callers (`event_log.rs`, `signal/longitudinal.rs`) are untouched. Default behaviour preserved. +- **`coverage.rs`** (new) — single-source-of-truth top-K coverage harness on a deterministic **anisotropic planted-cluster** fixture (cosine ground truth, the metric a sign sketch approximates). Backs both the `pass2_coverage_report` unit test and the `sketch_bench` coverage table. +- **Multi-bit Pass-3 experiment** — `coverage::measure_multibit`: rotate, then `b`-bit uniform scalar-quantize each coord, rank by L1 over codes. Measures the bit/coverage tradeoff. + +### 10.2 Pre-existing bug found and fixed (disclosed) + +Building the coverage harness surfaced a **pre-existing correctness bug in `SketchBank::topk`** (shipped in ADR-084): the `n > k` heap path used `BinaryHeap>` (a *min*-heap) but its comment/logic treated the peek as the max, so it evicted the *nearest* and returned the **k farthest** sketches as "nearest."

Pass-1/Pass-2 ranked candidates by raw Hamming over sign bits — a coarse proxy.

All external callers (`event_log.rs`, `signal/longitudinal.rs`, `sensing-server`) use Pass-1 `from_embedding` and are unaffected. + +### 11.2 The estimator formula (and the zero-centroid simplification, stated honestly) + +Let `P` be the Pass-2 orthogonal rotation (`R = H·D`), `D = next_pow2(dim)`. For data `o_raw`, query `q_raw`, centroid `c`: + +1. **Centroid — SIMPLIFIED to zero/global `c = 0`.** The paper centres on a per-cluster centroid (`o_r = o_raw − c`); we use `c = 0` (`o_r = o_raw`), because the current sketch path has no IVF/k-means cluster structure. This costs accuracy when the data is far off-origin. **We document it, do not hide it,** and built the paper-faithful centroid path (`from_embedding_centred` / `EstimatorBank::with_centroid`) so the simplification is a measured choice, not an assumption. (We do **not** report a centroid coverage number against the *cosine* ground truth: centroid-subtraction changes the metric — cosine-of-residual ≠ cosine-of-raw — so a centroid number vs raw-cosine truth would be a metric mismatch, itself dishonest. Zero-centroid is the correct match for this raw-cosine harness.) +2. **Unit residual + 1-bit code.** `o = o_r/‖o_r‖`, `o' = P·o`, code `x̄_i = sign(o'_i)·(1/√D)` — a unit vector at the nearest hypercube corner. +3. **Side info:** `residual_norm = ‖o_r‖` and `x_dot_o = ⟨x̄, o'⟩ ∈ (0,1]` (the paper's `⟨x̄, o⟩`). +4. **Unbiased estimator** (paper Eq.): `⟨o', q'⟩ ≈ ⟨x̄, q'⟩ / ⟨x̄, o'⟩ = ⟨x̄, q'⟩ / x_dot_o`. The random rotation makes the code's quantization error orthogonal **in expectation** to `q'`, so the rescale is unbiased (paper's `O(1/√D)` bound). Per candidate: one length-`D` signed sum (`x̄ ∈ {±1/√D}`), as cheap as Hamming + a multiply. +5. **Distance / cosine.** `⟨o_r,q_r⟩ = ‖o_r‖·(⟨x̄,q'⟩/x_dot_o)`; `‖q_r−o_r‖² = ‖q_r‖²+‖o_r‖²−2⟨o_r,q_r⟩`.

This is a **published negative**, the same class of honest result as the Pass-2 rotation (§10). +- **Why the strict-K gain is modest:** the binding constraint at strict K is the **1-bit code's information ceiling** (resolving 8-of-2048 from a single sign bit per coordinate), not the *estimator's variance* — the estimator sharpens the ranking but cannot add information the 1-bit code never captured. The estimator's larger wins are at over-fetch, where there is room to re-rank a wider candidate pool. +- **The bar is still met the way ADR-084 deploys the sensor:** at candidate_k=24 (~3× over-fetch) the estimator reaches **95.12%** (vs Pass-2-sign 91.60%) — the "candidate set, then full refinement" pattern.

Context + +The hardware/sensing-acquisition layer is the bottom of the stack: it turns raw RF (ESP32 CSI frames, multi-BSSID netsh scans, 802.11bf measurement reports) into typed, validated domain objects that the signal/fusion/NN layers above consume. A beyond-SOTA review of the four crates surfaced far **fewer** real defects than the signal (ADR-154) or fusion (ADR-156) sweeps — because this layer was written defensively from the start: length-gated parsers, `Option`-returning helpers, `#[serde(try_from)]` validate-on-deserialize, FSMs that return `Result` instead of panicking, and HMAC-authenticated + replay-protected TDM beacons. + +The genuine findings are three: an **O(n²) sliding-window data-structure choice** in the vital-sign extractors (perf, latent), a **partial-weights scale-mixing bug** in breathing fusion (correctness), and an **IIR resonator that can diverge at pathologically low sample rates** (stability). Everything else the review flagged turned out to be already-safe — documented in §3 as MEASURED negative results. + +--- + +## 2.

Six sites: + +| File | Site | Buffer | +|------|------|--------| +| `vitals/heartrate.rs` | `extract` history window | `Vec` → `VecDeque` | +| `vitals/breathing.rs` | `extract` history window | `Vec` → `VecDeque` | +| `vitals/anomaly.rs` | `rr_history` / `hr_history` | `Vec` → `VecDeque` (×2) | +| `vitals/store.rs` | `readings` ring buffer | `Vec` → `VecDeque` | +| `wifiscan/pipeline/breathing_extractor.rs` | filtered history | `Vec` → `VecDeque` | +| `wifiscan/pipeline/correlator.rs` | per-BSSID histories | `Vec>` → `Vec>` | + +**The fix.** Swap to `VecDeque` with `push_back` + `pop_front` (O(1) eviction). Where the autocorrelation / zero-crossing / Pearson loop needs a contiguous slice, call `make_contiguous()` (or `as_slices().0` after it) **once per `extract()`**. This matches the idiom already used correctly in `wifiscan/pipeline/orchestrator.rs`. **Output is bit-identical** — no behavior test bites; the change is bench-gated. + +**The honest measurement (§4).** In **isolation**, the eviction cost collapses from O(n²) to O(n): a microbenchmark of pure eviction shows **34.6× at window=3000 and 3158× at window=100000**. But in the **full `extract()` path at realistic ESP32 window sizes** (heartrate ~1500, breathing ~3000), the per-frame DSP (autocorrelation is O(window·lags); zero-crossing is O(window)) **dominates the eviction entirely**, so the end-to-end win is **below noise** — measured `heartrate` 42.8 ms (before) vs 44.4 ms (after), `breathing` 7.95 ms vs 7.86 ms: overlapping confidence intervals, **no measurable change**. We land A1 because it is the correct data structure and removes a latent O(n²) that *would* bite at higher sample rates or longer windows — **not** because it speeds up the current hot path, which it does not measurably. Claiming an end-to-end speedup here would be exactly the inflation this sweep exists to prevent (the same discipline ADR-156 §2.1 applied to its cos no-op). + +### 2.2 §A2 — `breathing.rs` partial-weights scale-mixing (CORRECTNESS, real) + +**The finding.** `BreathingExtractor::extract` fused per-subcarrier residuals as `Σ residuals[i]·w[i]` where `w[i] = weights.get(i).unwrap_or(1/n)`. The result was **never normalized**. When `weights` was supplied **shorter than** `n`, the supplied entries (e.g. attention weights ~10.0) were used **raw** while the missing tail defaulted to `uniform_w = 1/n` (~0.125) — two scales summed with no renormalization, **silently mis-scaling the breathing signal** by a factor that depends on `weights.len()`. A caller passing 2 high attention weights for an 8-subcarrier frame got a fused value ~20× too large. + +**The fix.** Extracted the fusion into `fuse_weighted_residuals(residuals, weights, n)` and normalized by `Σ(effective weights)` — `weighted_sum / weight_total` — mirroring the **already-correct** pattern in `heartrate::compute_phase_coherence_signal`. A partial weight slice now produces a true weighted average in the residual range, independent of `weights.len()`. + +**Tests (fail on old code, verified by reverting — §6):** +- `partial_weights_are_renormalized_not_scale_mixed` — `residuals=[1.0;8]`, `weights=[10.0,10.0]` → fused value `1.0` (the renormalized weighted mean), and explicitly **not** the old scale-mixed sum `2·10 + 6·0.125 = 20.75`. +- `partial_weights_fusion_is_weighted_average` — differing residuals → a proper weighted average within `[0, 2]`, which the old un-normalized sum is not. + +### 2.3 §A3 — IIR resonator divergence at pathologically low sample rate (STABILITY, real) + +**The finding.** Both extractors' `bandpass_filter` set the resonator pole radius `r = 1 - bw/2` with `bw = 2π(f_high − f_low)/fs`. The **research report's stated trigger ("`fs` below ~4 Hz") is incorrect**, and we say so: the resonator pole *magnitude* is `|r|`, and the filter is stable for any `|r| < 1` — a merely-**negative** `r` is still stable. Divergence requires `|r| ≥ 1`, i.e. `bw ≥ 4`, i.e. `fs` very low **relative to the band width** (e.g. `fs = 0.5` Hz with a 0.1–0.9 Hz band → `bw = 10.05`, `r = −4.03`, `|r| = 4.03 > 1`). When that holds, the filter **diverges exponentially**: a unit-step input reaches `~10^183` within 300 frames and **overflows f64 to ±inf within ~600 frames**. Once one inf enters `filtered_history`, the autocorrelation `acf0`/zero-crossing path produces NaN and the extractor is **permanently dead** (silent stall until `reset()`). + +**The fix.** Two layers of defense-in-depth: +1. **Clamp** `r` to a stable range: `r = (1.0 - bw/2.0).clamp(0.0, 0.9999)` — keeps the pole inside the unit circle for **any** sample-rate / band-edge configuration. (We document honestly that the divergence condition is `|r| ≥ 1`, not "`r` negative.") +2. **Finite-guard** before the history push: `if !filtered.is_finite() { return None; }` — mirrors the NaN-bypass guard in ADR-154 §3, so even a future divergence cannot poison the buffer. + +Applied to **both** `heartrate.rs` and `breathing.rs` (identical resonator block). + +**Tests (fail on old code, verified by reverting — §6):** `heartrate::low_sample_rate_filter_stays_finite` and `breathing::low_sample_rate_filter_stays_finite` — construct at `fs=0.5` with a 0.1–0.9 Hz band, feed a unit step for 600 frames, assert **every** `filtered_history` sample is finite. On the old code these **panic** (a `filtered_history[i]` is inf/NaN); on the new code all samples are finite. + +### 2.4 §D1 — new `vitals/benches/vitals_bench.rs` (MEASURED) + +A new criterion bench (`harness = false`, registered in `Cargo.toml`) drives each extractor from empty to a full window (`heartrate` 1500 samples, `breathing` 3000) so the A1 sliding-window bookkeeping is exercised across the whole buffer. Follows the criterion style of the existing `hardware/benches/transport_bench.rs` and ADR-156's `fusion_bench`. Numbers and the honest interpretation are in §4. + +### 2.5 §B1 — `ieee80211bf/transport.rs` drop-instead-of-truncate (HARDENING, unreachable path — disclosed) + +`OpportunisticCsiBridge::ingest` built `CsiReportPayload { n_subcarriers: self.amp_accum.len() as u16, … }`. The `as u16` would silently wrap a count above 65 535. **This is unreachable in practice**: `ingest` gates `frame.subcarrier_count() > MAX_REPORT_SUBCARRIERS` (484) at entry and returns `None`, and `report.validate()` independently rejects oversized counts downstream. We replaced the cast with `u16::try_from(self.amp_accum.len()).ok()?` (drop-instead-of-truncate) so the construction is **correct-by-construction** rather than relying on the upstream gate. We disclose this as **defense-in-depth on an unreachable path, not a live bug** — no behavior change, no new test (the gate already prevents the input that would exercise it). + +### 2.6 §B4 — constant-time HMAC tag compare: **RESOLVED — no-dependency hand-rolled constant-time compare (Milestone-1)** + +`secure_tdm.rs` compared the 8-byte HMAC tag with `self.hmac_tag == expected` (data-dependent, non-constant-time: short-circuits on the first differing byte, leaking through verification latency how many leading bytes a forged tag matched — a byte-by-byte tag-recovery oracle). Milestone-3 deferred this **only** to avoid adding the `subtle` crate as a direct dependency. Milestone-1 resolves it **without any dependency**: a hand-rolled `constant_time_tag_eq(a, b)` that XOR-accumulates every byte difference into a single `u8` with **no early exit**, then compares the accumulator to zero exactly once. `#[inline(never)]` + `core::hint::black_box(diff)` stop the optimizer from reintroducing a short-circuit or lowering the loop into a non-constant-time `memcmp`; a length mismatch returns `false` without inspecting contents. The former `==` verify site now calls this helper. + +**Test (fails on old code, the hard gate):** `tag_compare_is_constant_time_shape` — asserts correct accept/reject for equal, first-byte-differ, last-byte-differ, all-byte-differ, and length-mismatch tags, plus an end-to-end `verify()` last-byte-only tamper. Verified to **bite**: introducing a classic constant-time bug (loop `take(LEN-1)`, skipping the last byte) makes it fail on `last-byte-differ must reject`. A coarse timing-invariance smoke check `tag_compare_timing_invariance_smoke` exists but is `#[ignore]`d (noisy host — not a CI gate). **Grade MEASURED** (constant-time *construction*; micro-timing on a noisy host is only a smoke check, disclosed honestly). Tracked RESOLVED in §8. + +--- + +## 3. The MEASURED negative-results section (the centerpiece — what was investigated and found already-correct) + +This is the core of ADR-157.

The total-frame-size length gate (`data.len() < HEADER_SIZE + n_antennas·n_subcarriers·2 → Err`) dominates **every** subsequent `data[byte_offset]`/`[+1]` access; `n_subcarriers ≤ 256`, `n_antennas ≤ 4` are header-bounded, and the `index` math is pure i16 arithmetic with no indexing. | `esp32_parser.rs:211` (length gate) guards the loop at `:224–242` | **Already safe — NO ACTION** | +| **`sync_packet.rs` `try_into().unwrap()`** | The four `try_into().unwrap()` calls are **infallible**: each slices a fixed-width sub-range (`[0..4]`, `[8..16]`, `[16..24]`, `[24..28]`) of a buffer already guaranteed `len() >= SYNC_PACKET_SIZE` (32) by the early `return Err(InsufficientData)`. | `sync_packet.rs:88` (length gate) → `:94,102,103,104` (fixed-width slices) | **Already safe — NO ACTION** | +| **The entire `ieee80211bf/` 802.11bf model** | Validate-on-deserialize and no-panic-by-construction throughout. `MeasurementSetupId` is `#[serde(try_from = "u8")]` rejecting `> MAX_SETUP_ID` (127); `ThresholdParams` is `#[serde(try_from = "RawThresholdParams")]` routing every deserialize through `ThresholdParams::new`; the session FSM `handle()` returns `Result, BfError>` (never panics) and enforces **single-role** (`self.role != Initiator/Responder → Err`) on every transition; the SBP request is validated through the **same** single `evaluate_setup` chain as a direct setup (no SBP-only policy bypass). | `types.rs:160–161` (setup-id try_from), `:225–226` (threshold try_from), `:165` (range check); `session.rs:118` (`handle` → Result), `:130/143/166/182` (single-role), `messages.rs:130–147` (SBP single-evaluate) | **Already SOTA-shaped — NO ACTION** | +| **`secure_tdm.rs` HMAC + replay** | Beacon authentication (HMAC-SHA256, 8-byte tag), tamper rejection, and replay-window protection are correct and tested.

Milestone-1 **measured both paths on this box** (Intel Wi-Fi 7 BE201 320MHz, 2026-06-13) over an identical 10 s wall-clock window via a new `benchmark_backend`: **native 21.42 Hz vs netsh 3.84 Hz = 5.57× MEASURED** (mean 5.0 BSSIDs/scan each; native-only run 18.0 Hz). Native genuinely beats netsh — a real measured multiple, **not** a fabricated 10×; the achieved 21.4 Hz lands in the asserted >2 Hz regime though below the asserted 10–20 Hz upper bound. 50 back-to-back native scans = 50/50 OK, no handle leak. → §8 MEASURED. | + +--- + +## 6.

Lib-test counts: `wifi-densepose-vitals` **55** (was 51; +4 net new bug-catching tests — two §A2, two §A3), `wifi-densepose-hardware` **163**, `wifi-densepose-wifiscan` **87**, `wifi-densepose-calibration` **58**. 0 failures across all four. +- **`cd v2 && cargo test --workspace --no-default-features`** — **3054 passed / 0 failed** (M2 left the workspace at 3050; the +4 net new bug-catching tests are included and green). +- **`python archive/v1/data/proof/verify.py`** — **`VERDICT: PASS`**, pipeline hash unchanged `f8e76f21…46f7a` (these are Rust-only changes; the Python pipeline proof is independent and confirmed unaffected). +- New `vitals_bench` compiles and runs under the default feature set. +- **Disclosed validation limits:** the live-QUIC transport in `secure_tdm` is **structurally** tested (HMAC compute/verify, tamper, replay-window) but **not live-socket-tested** in CI; the serde-gated `ieee80211bf` types are additionally verifiable with `--features serde`. Clippy is not installed in the local 1.89 toolchain, so the per-crate lint pass was not run locally (the project gate is `cargo test`). + +--- + +## 7. What changed, file by file + +- `vitals/heartrate.rs` — `filtered_history: Vec` → `VecDeque` (`push_back`/`pop_front`, `make_contiguous` once per `extract`); resonator `r` clamped to `[0, 0.9999]`; finite-guard before history push; corrected divergence-condition doc (`|r| ≥ 1`, not "`r` negative"); `low_sample_rate_filter_stays_finite` test. +- `vitals/breathing.rs` — same `VecDeque` + clamp + finite-guard changes; weighted fusion extracted to `fuse_weighted_residuals` and **normalized by Σ(effective weights)** (the §A2 fix); three new tests (two A2, one A3). +- `vitals/anomaly.rs`, `vitals/store.rs` — sliding/ring buffers → `VecDeque` (O(1) eviction); `store::history` takes `&mut self` to hand back a contiguous slice via `make_contiguous` (no external callers; observable contents unchanged). +- `wifiscan/pipeline/breathing_extractor.rs` — `VecDeque` + `make_contiguous`. +- `wifiscan/pipeline/correlator.rs` — per-BSSID histories → `Vec>`; contiguous-ize each touched buffer once before the Pearson pass. +- `hardware/ieee80211bf/transport.rs` — `n_subcarriers: … as u16` → `u16::try_from(…).ok()?` (§B1 drop-instead-of-truncate, unreachable-path hardening). +- `vitals/Cargo.toml` + `vitals/benches/vitals_bench.rs` (new) — criterion dev-dep, `[[bench]]`, the §D1 full-window benches. + +--- + +## 8. Deferred backlog (NOT silently dropped) + +- **§B4 constant-time HMAC compare** — **RESOLVED (Milestone-1).** Replaced the short-circuiting `==` on the 8-byte tag with a hand-rolled branch-free `constant_time_tag_eq` (XOR-accumulate, no early exit, `#[inline(never)]` + `black_box`). **No new dependency** — the `subtle` crate was the only reason this was deferred, and a fixed 8-byte compare needs none. Pinned by `tag_compare_is_constant_time_shape` (proven to fail on a last-byte-skipping bug). Grade MEASURED (constant-time construction). See §2.6. +- **802.11bf SBP conformance vectors** (§5 #2) — add real conformance test vectors to the `ieee80211bf/` model **when the Wi-Fi Alliance / WBA publishes a public test plan**. Do not invent vectors before then. +- **Geometry-conditioned LoRA calibration head** (§5 #3) — built-but-unconsumed and **data-gated** on paired multi-room PCK data (ADR-152 measurement (b): data, not architecture, is the bottleneck). ACCEPTED-FUTURE. +- **Native `wlanapi.dll` FFI multi-BSSID fast path** (§5 #4) — **RESOLVED + MEASURED (Milestone-1).** The native FFI is implemented and wired live (native-first, netsh fallback). Measured on this box (Intel Wi-Fi 7 BE201 320MHz, 2026-06-13): **native 21.42 Hz vs netsh 3.84 Hz = 5.57×**, mean 5.0 BSSIDs/scan, 50/50 native scans with no handle leak. Real positive result — no fabricated 10×. See §5 #4. (Note: a prior sweep recorded 9.74 Hz on a different/older adapter; the per-adapter number varies, the ratio over netsh is the claim.) +- **Deep-CSI vital-sign model** (§5 #1) — DATA-GATED on paired PPG/ECG ground truth. No public ESP32 artifact reproduces the cited ~2–3 BPM MAE. Not on the near-term path. + +--- + +## 9. Consequences + +**Positive.** The vital-sign extractors now use the correct O(1)-eviction data structure (no latent O(n²)), cannot mis-scale a breathing estimate from a partial attention-weight slice, and cannot be silently killed by a diverging IIR filter at a pathological sample rate. The 802.11bf construction site drops-instead-of-truncates on an (already-gated) oversized count. Most importantly, the layer's existing hardening — length-gated parsers, infallible fixed-width slices, validate-on-deserialize, no-panic FSMs, fixed-argv scanning, HMAC+replay TDM, overflow-clamped geometry embeddings — is now **documented as MEASURED negative results** with file:line evidence, so a reader can verify the "already safe" claims rather than take them on faith. + +**Negative / honest limits.** The §A1 perf change is **null end-to-end** at realistic window sizes — we land it for correctness, not speed, and the committed bench proves the null rather than hiding it. The research report's stated §A3 divergence trigger ("`fs` below ~4 Hz") was **physically inaccurate** (divergence needs `|r| ≥ 1` ⇒ `bw ≥ 4`, a far lower `fs`); we corrected it in the code comments and the test parameters and disclose the correction here. The strongest external SOTA candidates (deep-CSI vitals, learned calibration, native FFI scanning) are **all NO-ACTION or ACCEPTED-FUTURE** — data-gated, unmeasured, or blocked on a non-public conformance suite — and **none is presented as more than it is.** §B4 is consciously deferred.

It never called +`state.tokens().is_valid()` — the check the REST path uses via +`auth::BearerAuth`. With a provisioned `HOMECORE_TOKENS` whitelist, **any +attacker-chosen non-empty token got full WS access** (read all states, call any +service, subscribe to all events). + +**Real fix:** the handshake now calls +`state.tokens().is_valid(&token).await` (the *same* store + method as REST). +A wrong token receives `auth_invalid` and the socket closes. DEV (`allow_any`) +mode still accepts any non-empty bearer with a warn, so smoke tests keep +working; the empty token is rejected inside `is_valid`. + +**Failing-on-old test** (`tests/ws_handshake.rs`): +`wrong_token_is_rejected` — provisions a real (non-dev) store with one good +token, sends a DIFFERENT non-empty token over the WS handshake, asserts +`auth_invalid`. On the old source the client received +`{"type":"auth_ok",…}` (verified: the test panics on old `ws.rs` with +`left: "auth_ok", right: "auth_invalid"`). Companion: `correct_token_is_accepted`. +**Grade: MEASURED. This is the milestone headline.** + +### §A2 — WS replies never transmitted (HIGH, functional) — MEASURED + +`ws.rs::Connection::run` moved the socket into a recv-only task; the only +consumer of the response mpsc just did `debug!("ws emit: {msg}")` and dropped +every message. No command reply ever reached the wire. + +**Real fix:** the socket is split with `futures_util::StreamExt::split`. A +dedicated **writer task** drains the response channel onto `sink.send(...)` +(text frames; a `__pong:` sentinel maps to a Pong control frame); the reader +task parses commands concurrently. On reader exit the senders drop and the +writer task ends cleanly. + +**Failing-on-old tests:** `result_reply_is_received` (connect → auth → +`get_states` → assert a `result` reply is RECEIVED within 5s) and +`ping_pong_reply_is_received`. Both time out on the old source (verified: +`Elapsed` panic). **Grade: MEASURED.** + +### §A8 — `homecore-api` bin: no env-token path, network-exposed (HIGH, security) — MEASURED + +`homecore-api/src/bin/server.rs` bound `0.0.0.0:8123` with +`SharedState::new()` → `allow_any_non_empty()` and **no** `HOMECORE_TOKENS` +path (unlike `homecore-server`), so a provisioned operator had no way to lock +it down. + +**Real fix:** the bin now mirrors `homecore-server`'s provisioning — prefer the +`HOMECORE_TOKENS` whitelist (`LongLivedTokenStore::from_env()`), fall back to an +**explicitly warn-logged** DEV mode only when unset. It also defaults the bind +address to **`127.0.0.1`** (loopback) so a bare `cargo run` is not +network-exposed, with `HOMECORE_BIND` to opt into LAN. + +**Failing-on-old test** (`tests/server_bin_auth.rs`): +`provisioned_bin_rejects_wrong_bearer` reproduces the bin's exact provisioning +path (a populated, non-dev store) and asserts a wrong bearer → 401; +`from_env_path_enforces_whitelist` proves `from_env()` is not dev mode and +enforces the list. The old bin's `allow_any_non_empty()` accepted the wrong +bearer. **Grade: MEASURED.** + +### §A3 — Automation engine never started (HIGH) — MEASURED + +`homecore-server/src/main.rs` did `let _automation_engine = AutomationEngine::new(...)` +then dropped it immediately, while the header doc claimed "Automation engine +subscribed to the state machine." + +**Real fix:** the engine is now built into a long-lived binding and `.start()` +is called, spawning the event loop + timer task; the header/log lines state it +is started with N automations and which trigger classes are active. (With A4–A7 +the running engine is genuinely functional, not theater.) + +**Evidence:** the engine-behavior tests below run against the same +`AutomationEngine::start()` path now wired into the bin. **Grade: MEASURED.** + +### §A4 — `Trigger::Time` hard-coded `false`, no timer (HIGH) — MEASURED + +`trigger.rs::matches_sync` returned `false` for `Time` and there was **no timer +task** anywhere, so time automations could never fire. + +**Real fix:** `AutomationEngine::start_timer` — a 1 Hz tokio interval that +compares each `time:` automation's `at` (`HH:MM` or `HH:MM:SS`) against the +local wall-clock second and fires it once per match (conditions still gate it). +`matches_sync` returning `false` for `Time` is now **correct and documented** +(it is a wall-clock trigger with no state-change context); a public +`fire_time_for_test` exposes the same path deterministically. + +**Failing-on-old test** (`tests/engine_behaviors.rs`): +`time_trigger_fires_via_timer_path` (+ unit `time_at_matches_handles_hh_mm_and_hh_mm_ss`). +The method does not exist on the old engine. **Grade: MEASURED.** + +### §A5 — `RunMode` documented as AtomicBool-enforced but unbounded-parallel (HIGH) — MEASURED + +`engine.rs` doc claimed "RunMode::Single is enforced via a per-automation +AtomicBool" — but no such code existed and **every** trigger spawned an +unbounded parallel task regardless of `mode`. + +**Real fix:** each registered automation carries a `running: Arc`. +`Single`/`IgnoreFirst` modes `compare_exchange` the flag before spawning and +**skip** the trigger if a run is already in flight, clearing it on completion; +`Parallel` (and, for now, `Restart`/`Queued`) spawn on every trigger. + +**Failing-on-old tests** (`tests/engine_behaviors.rs`): +`single_mode_does_not_double_fire_on_rapid_triggers` (two rapid triggers while +the first run sleeps → exactly **1** run; old code fired **2**, verified) and +`parallel_mode_does_fire_concurrently` (→ 2). **Grade: MEASURED (Single/Parallel +honored; bounded `Queued`/`Restart`/`max` ordering → ACCEPTED-FUTURE, see below).** + +### §A6 — `Action::Choose` ignored branches (HIGH) — MEASURED + +`action.rs` discarded `choices` and always ran `default`. + +**Real fix:** `ChoiceBranch::matches` deserialises each branch's +`serde_yaml::Value` conditions into `Condition` and evaluates them (AND +semantics, against an `EvalContext` now carried on `ExecutionContext`). `Choose` +runs the **first matching branch's** sequence and falls to `default` only if +none match. + +**Failing-on-old tests** (`action.rs` inline): +`choose_runs_matching_branch_not_default` (matching branch runs, default does +NOT — old code ran default, verified) and +`choose_falls_to_default_when_no_branch_matches`. **Grade: MEASURED.** + +### §A7 — Template conditions always false in the live engine (MEDIUM) — MEASURED + +`condition.rs` returned `false` for `Template` whenever `template_env` was +`None`, and the engine built every `EvalContext` with `template_env: None` +(`EvalContext::new`), so `template:` conditions could never be true in +production — only in unit tests that hand-built a template env. + +**Real fix:** the engine constructs one `TemplateEnvironment` over the state +machine and threads it into every `EvalContext` via +`EvalContext::with_templates` (event loop, timer task, and +`ExecutionContext` for `Choose` branches). + +**Failing-on-old tests** (`tests/engine_behaviors.rs`): +`template_condition_evaluates_true_in_engine` (a `{{ is_state(...) }}` condition +gates an action true) and `template_condition_evaluates_false_blocks_action`. +On the old engine the action never ran (template always false, verified). +**Grade: MEASURED.** + +### §B5 — Plugin manifest sig/hash "verified before execution" doc was false (LOW, honesty) — relabeled + +`homecore-plugins/src/manifest.rs` documented `wasm_module_hash` as "verified +before execution" and carried `wasm_module_sig` / `publisher_key`, but these +fields are **never read** for verification (only ever set to `None` in tests). + +**Fix (honest labeling — no false capability claimed):** the three fields are +re-doc'd **"(P4 — not yet enforced, ADR-161/B5)"** — parsed and round-tripped, +but no integrity/signature check happens before a plugin runs.

It is untrusted in +the security sense: the schema can drift between HA releases, and silently mis-parsing a +registry would corrupt the imported home. ADR-164 flagged this as a CRITICAL coverage gap — +a data-integrity-sensitive importer governed by a non-existent ADR identity. + +The decision an ADR must pin here is the **trust boundary and import contract**: which HA +files are read, how schema versions are validated, and what happens on an unknown version. + +## 2.

But it trained in a *different* camera's frame, so the inferred +skeleton never lined up with the laptop camera. Doing capture + train + infer all +in the browser with the **same** camera makes the training frame and the +inference frame identical → the skeleton aligns. + +## Compute backends (WebGPU / WASM / WebGL) + +Training and inference run on TensorFlow.js.

The page expects +the verified live endpoint **`ws://localhost:8765/ws/sensing`** with +`source:"esp32"`, nodes `[9, 13]`, `features.*`, `node_features[].features.*`, +and `signal_field.values` (400 floats). + +### 2. Serve this page over localhost (camera + WebGPU need a localhost/secure origin) + +Any static localhost server works. For example: + +```bash +python -m http.server 8099 +# then open: http://localhost:8099/examples/through-wall/wiflow_browser.html +``` + +(8099 is just the static file server — 8765 is a separate process, the CSI +WebSocket.)

Use it + +1. **CAPTURE** tab → *enable laptop camera* → *start recording*. Follow the guided + routine (stand / turn / walk / arms / crouch / sit). A pair is stored only when + a confident pose AND a fresh live `esp32` CSI frame coexist. Aim for a few + thousand samples. Samples persist in IndexedDB across refreshes. +2. **TRAIN** tab → *train model*. Watch the live loss curve, held-out PCK, and the + baseline verdict. The model saves to IndexedDB. +3. **INFER** tab → the green skeleton is now driven by WiFi CSI only, aligned over + your camera. Toggle *hide camera* to see the CSI-only skeleton on black. + +## The 410-d CSI vector (matches the Python pipeline exactly) + +``` +[ mean_rssi, variance, motion_band_power, breathing_band_power ] # 4 (features.*) ++ for node 9 then node 13: [ mean_rssi, variance, motion_band_power ] # 6 (node_features[].features.*) ++ signal_field.values, padded / truncated to 400 # 400 += 410-d +``` + +Verified against a real live frame: the in-browser `csiVector()` produces the +identical 410 vector as `wiflow_capture.py`'s `csi_vector()` (node 9 first, then +node 13; field zero-padded). + +## Libraries (CDN only, no bundler) + +| Library | CDN | +|---|---| +| TensorFlow.js core | `@tensorflow/tfjs@4.22.0/dist/tf.min.js` | +| TF.js WebGPU backend | `@tensorflow/tfjs-backend-webgpu@4.22.0/dist/tf-backend-webgpu.min.js` | +| TF.js WASM backend | `@tensorflow/tfjs-backend-wasm@4.22.0/dist/tf-backend-wasm.min.js` | +| MediaPipe Pose 0.5 (legacy solutions) | `@mediapipe/pose@0.5/pose.js` | + +## Scope / honesty caveats + +Same person, same room, same session. **Not** validated cross-day, cross-room, or +through-wall.

The +latter is the only honest sense in which an ESP32 "helps scramble" a signal, and +it does so without the ESP32 emitting any RF of its own. + +--- + +## The three legitimate roles + +### 1. `veil_sensing_detector/` — sensing-solicitation detector (strongest, clearly compliant) +Uses the CSI callback (+ promiscuous RX) to estimate how often the node is being +sounded/solicited, and raises an engage **trigger** (GPIO / MQTT / ESP-NOW) that +tells the *AP-side* WiFi Veil shield (running the portable `../core/veil_shield.c`) to +turn on. Pure observe-plus-control-signal; the ESP32 shapes nothing on air. This +is the role we would actually build first. + +### 2. `veil_ris_controller/` — external RIS driver (the honest "help scramble") +Drives a **reconfigurable intelligent surface** over GPIO/SPI. Following the +PrivISAC pattern, each surface element has two phase states designed offline so +the array response is ~identical in the *communication* direction (throughput +preserved) but differs sharply in the *sensing* direction (an eavesdropper's +channel is perturbed). The ESP32 is just a keyed pin-driver; the surface is +**passive** (re-reflects ambient energy, adds none), which is what keeps this on +the compliant side of the jamming line. The switching **schedule is keyed** via +the portable core's `veil_rng` (SplitMix64), so an authorized sensor holding the +key can reconstruct and tolerate the schedule while an eavesdropper cannot. + +### 3. `esp_wifi_80211_tx` action-frame signaling (minor) +Not a separate component. The trigger in role 1 could ride an action frame via +`esp_wifi_80211_tx` instead of GPIO/MQTT/ESP-NOW. Useful only as a transport for +the control signal — it does **not** touch beamforming feedback. + +--- + +## Not recommended: decoy / cover-traffic + +One could have the ESP32 emit extra frames (via `esp_wifi_80211_tx`) to inject +motion-like or clutter-like variation into an observer's CSI ("cover traffic"). +**We do not implement this and do not recommend it.** It is (a) **legally +sensitive** — deliberately adding channel-occupying transmissions to degrade +another party's reception sits close to the *jamming* line and can violate +radio regulations depending on rate, power, and intent; and (b) **low-value** — +it costs airtime, harms your own network, and a determined observer can often +filter periodic decoys. It is documented here only so the option is explicitly +weighed and rejected in favor of the passive-RIS approach (role 2), which +perturbs the *sensing* direction without occupying spectrum. + +--- + +## Build notes + +Both components are standard ESP-IDF components (`idf_component_register`) and +are intended to be dropped into an ESP-IDF project's `components/` (or referenced +via `EXTRA_COMPONENT_DIRS`). `veil_ris_controller` compiles the portable core +(`../core/veil_shield.c`) directly to reuse `veil_rng`.

Published reverse-engineering of these chips reports that the D11 +generates the **VHT/HE compressed beamforming report ~10 µs after the NDP**, with +its contents fetched from an **internal memory updated directly by the hardware** +on NDP reception. In other words, the angles WiFi Veil wants to touch are staged and +emitted inside the ucode/PHY path on a microsecond deadline — *below* the ARM +"wl" driver firmware where Nexmon's C hooks (`__attribute__((at(addr, ...)))` +flashpatches / branch hooks) live most reliably. Reaching them means either a +D11-ucode patch (needs the D11 assembler and SHM/template-RAM layout) or catching +the report while the ARM path still assembles the action-frame body — if it does +so on this chip at all. Both are `TODO(reverse-engineer)`. + +## Target chip(s) + +Primary: **BCM43455c0** (Raspberry Pi 3B+/4B; also RPi Zero 2 W), firmware +**7_45_154** (Raspbian) or **7_45_189** (Cypress) — the best-documented, +most-reproducible Nexmon target, and one of the four chips `nexmon_csi` already +supports. Secondary candidates that `nexmon_csi` also supports: **BCM4339** +(Nexus 5), **BCM4358** (Nexus 6P), **BCM4366c0** (Asus RT-AC86U). We scope the +skeleton to BCM43455c0 / 7_45_189 and leave the others as build-matrix `TODO`s. + +Caveat: the RPi BCM43455c0 is an **802.11ac (VHT)** single-stream part; its own +*transmit* beamforming/sounding activity as a beamformee is limited. The +skeleton targets the **VHT compressed beamforming report** action-frame path; +whether this chip emits enough to shape in practice is itself a `TODO(hw)` +question. + +## Hook-point candidates (all `TODO(reverse-engineer)`) + +Ordered most-tractable → deepest. Addresses are **placeholders** — real offsets +come from disassembling the specific firmware blob and cross-checking the Nexmon +symbol tables (`wl_ram.elf` / IDA); none are known-good here. + +1. **ARM action-frame TX assembly (best first target).** If the "wl" driver + assembles the VHT Compressed Beamforming Report action-frame *body* in ARM + firmware before handing it to the D11 (function family around + `wlc_txbf_*` / a `wlc_send*mgmt`/action path), a branch hook there could + locate the report's fine-angle block and call `veil_shield_apply` in place. + Cheapest if it exists on this chip. +2. **ARM → D11 TX descriptor / template handoff.** Hook where the driver stages + a frame into the D11 TX FIFO / template RAM (`wlc_d11hdrs` / `wlc_txfifo` + region) and rewrite the angle bytes there. Requires knowing the exact + template-RAM offset of the report body. +3. **D11 ucode patch (deepest).** Patch the ucode routine that copies angles + from the hardware-updated internal memory into the outgoing report, applying + the rotation in D11 SHM.

Home Assistant compatibility means the +documented core REST/WebSocket contract, not every endpoint supplied by the +Home Assistant integration ecosystem. HAP protocol tests are not Apple +certification. STT/TTS provider contracts do not imply that a deployment has a +real speech provider. + +Every guidance result cites repository paths, focused validation commands, and +known limitations.

Users +//! in notebooks rarely need to compare UUIDs structurally; strings +//! are good enough and don't require binding `FrameId` / +//! `Timestamp` as separate classes. +//! +//! 3. **`PersonPose` is mutable** via `set_keypoint` / `set_bbox` / +//! `set_id` — it's a builder-style type users construct +//! incrementally. Hence NOT `#[pyclass(frozen)]`. +//! +//! 4. **`PoseEstimate` is frozen** — once constructed, the list of +//! persons + the metadata don't change. + +use std::collections::HashMap; + +use pyo3::prelude::*; +use pyo3::types::PyDict; + +use wifi_densepose_core::{ + BoundingBox, Confidence, KeypointType, PersonPose, PoseEstimate, +}; + +use super::keypoint::{PyKeypoint, PyKeypointType}; + +// ─── BoundingBox ───────────────────────────────────────────────────── + +/// Axis-aligned bounding box around a detected person. +/// +/// Python: +/// ```python +/// from wifi_densepose import BoundingBox +/// +/// bb = BoundingBox(0.1, 0.2, 0.5, 0.7) +/// print(bb.width, bb.height, bb.area, bb.center) +/// bb2 = BoundingBox.from_center(0.3, 0.45, 0.4, 0.5) +/// print(bb.iou(bb2)) +/// ``` +#[pyclass(frozen, name = "BoundingBox")] +#[derive(Clone)] +pub struct PyBoundingBox { + inner: BoundingBox, +} + +#[pymethods] +impl PyBoundingBox { + #[new] + fn new(x_min: f32, y_min: f32, x_max: f32, y_max: f32) -> Self { + Self { inner: BoundingBox::new(x_min, y_min, x_max, y_max) } + } + + /// Construct from center point + width + height. + #[staticmethod] + fn from_center(cx: f32, cy: f32, width: f32, height: f32) -> Self { + Self { inner: BoundingBox::from_center(cx, cy, width, height) } + } + + #[getter] + fn x_min(&self) -> f32 { self.inner.x_min } + #[getter] + fn y_min(&self) -> f32 { self.inner.y_min } + #[getter] + fn x_max(&self) -> f32 { self.inner.x_max } + #[getter] + fn y_max(&self) -> f32 { self.inner.y_max } + #[getter] + fn width(&self) -> f32 { self.inner.width() } + #[getter] + fn height(&self) -> f32 { self.inner.height() } + #[getter] + fn area(&self) -> f32 { self.inner.area() } + #[getter] + fn center(&self) -> (f32, f32) { self.inner.center() } + + /// Intersection over Union (IoU) with another box.

This section catalogs each validation requirement and its current status. - -#### Sensor Data Validation - -| Check | Required In | Status | Notes | -|-------|------------|--------|-------| -| `sample_rate_hz > 0` | `MultiChannelTimeSeries::new` | **MISSING** | Constructor accepts `sample_rate_hz` without validating it is positive and finite. Division by zero in `duration_s()` if zero. | -| `num_channels > 0` | `MultiChannelTimeSeries::new` | PASS | Returns error if `data.len() == 0`. | -| Channel lengths equal | `MultiChannelTimeSeries::new` | PASS | Validates all channels have the same length. | -| Non-NaN/Inf values | All signal processing | **MISSING** | No validation that input signals contain only finite f64 values. NaN propagation through FFT, PLV, and connectivity metrics produces silent garbage. | -| `num_samples > 0` | `AdcReader::read_samples` | PASS | Returns error if `num_samples == 0`. | -| Channel count > 0 | `AdcReader::read_samples` | PASS | Returns error if no channels configured. | -| Channel index bounds | `AdcReader::load_buffer` | PASS | Returns `ChannelOutOfRange` error. | -| `sensitivity > 0` | `SensorChannel` | **MISSING** | `sensitivity_ft_sqrt_hz` is a public field with no validation on construction. | -| `sample_rate > 0` | `SensorChannel` | **MISSING** | `sample_rate_hz` is a public field with no validation. | - -**Recommendation**: Add a `SensorChannel::new()` constructor that validates `sensitivity_ft_sqrt_hz > 0`, `sample_rate_hz > 0`, and that the orientation vector is a unit normal. Add `sample_rate_hz > 0` and `sample_rate_hz.is_finite()` checks to `MultiChannelTimeSeries::new`. Add a `validate_finite()` utility for signal data. - -#### Graph Construction Validation - -| Check | Required In | Status | Notes | -|-------|------------|--------|-------| -| Edge indices < `num_nodes` | `BrainGraph::adjacency_matrix` | PARTIAL | Silently skips out-of-bounds edges rather than reporting an error. This masks data corruption. | -| Edge weight is finite | `BrainGraph` | **MISSING** | `BrainEdge.weight` is not validated. NaN/Inf weights propagate silently through Stoer-Wagner and spectral analysis. | -| `num_nodes >= 2` | `stoer_wagner_mincut` | PASS | Returns proper error. | -| `num_nodes >= 2` | `fiedler_decomposition` | PASS | Returns proper error. | -| `num_nodes >= 2` | `SpectralEmbedder::embed` | PASS | Returns proper error. | -| `num_nodes >= 2` | `cheeger_constant` | PASS | Returns proper error. | -| Self-loops | `BrainGraph` | **MISSING** | No validation that `source != target` on edges. Self-loops could inflate degree calculations. | - -**Recommendation**: Add a `BrainGraph::validate()` method that checks all edge indices are within bounds, weights are finite, and no self-loops exist. Call it from `stoer_wagner_mincut`, `spectral_bisection`, and `SpectralEmbedder::embed`. Consider making `adjacency_matrix()` return `Result` with an error for out-of-bounds edges instead of silently ignoring them. - -#### RVF Format Validation - -| Check | Required In | Status | Notes | -|-------|------------|--------|-------| -| Magic bytes | `RvfHeader::validate` | PASS | Validates against `RVF_MAGIC`. | -| Version | `RvfHeader::validate` | PASS | Rejects unknown versions. | -| Header length | `RvfHeader::from_bytes` | PASS | Checks `bytes.len() < 22`. | -| Data type tag | `RvfDataType::from_tag` | PASS | Returns error for unknown tags. | -| `metadata_json_len` overflow | `RvfFile::read_from` | **CONCERN** | `metadata_json_len` is cast from `u32` to `usize` and used to allocate a `Vec`. A malicious file with `metadata_json_len = u32::MAX` (~4 GB) would cause an OOM allocation. | -| Payload length | `RvfFile::read_from` | **CONCERN** | `read_to_end` reads unbounded data into memory. A malicious file could exhaust memory. | -| JSON validity | `RvfFile::read_from` | PASS | Uses `serde_json::from_slice` which returns an error on invalid JSON. | -| `num_entries` vs actual data | `RvfFile::read_from` | **MISSING** | The header declares `num_entries` and `embedding_dim`, but these are never cross-checked against the actual payload size. | - -**Recommendation**: Add maximum size limits for `metadata_json_len` (e.g., 16 MB) and total payload size. Validate that `num_entries * entry_size_for_type <= data.len()` after reading. Use `Read::take()` to cap reads. - -#### Embedding Validation - -| Check | Required In | Status | Notes | -|-------|------------|--------|-------| -| Non-empty vector | `NeuralEmbedding::new` (core) | PASS | Returns error for empty vectors. | -| Non-empty vector | `NeuralEmbedding::new` (embed) | PASS | Returns error for empty vectors. | -| Dimension match | `cosine_similarity`, `euclidean_distance` | PASS | Returns `DimensionMismatch` error. | -| Zero-norm handling | `cosine_similarity` | PASS | Returns 0.0 for zero-norm vectors. | -| NaN/Inf in vector | `NeuralEmbedding::new` | **MISSING** | No check for non-finite values in the embedding vector. | - -#### Memory Store Validation - -| Check | Required In | Status | Notes | -|-------|------------|--------|-------| -| Capacity > 0 | `NeuralMemoryStore::new` | **MISSING** | Capacity 0 is accepted, producing a store that evicts on every insertion. | -| k > 0 | `query_nearest` | **MISSING** | k=0 produces an empty result silently (acceptable but undocumented). | -| Dimension consistency | `NeuralMemoryStore::store` | **MISSING** | No check that all stored embeddings have the same dimensionality. Mixed dimensions cause silent errors in `query_nearest`. | - -#### JSON Parsing - -| Check | Status | Notes | -|-------|--------|-------| -| Uses serde derive | PASS | All types use `#[derive(Serialize, Deserialize)]`. No manual parsing anywhere. | -| No `unsafe` JSON parsing | PASS | Standard `serde_json` throughout. | - ---- - -### Memory Safety - -| Check | Status | Notes | -|-------|--------|-------| -| No `unsafe` code | PASS | Zero `unsafe` blocks across all crates. | -| Vec instead of raw pointers | PASS | All data structures use `Vec`, `HashMap`, `BinaryHeap`. | -| ndarray for matrix ops | **NOT USED** | Despite being listed in `workspace.dependencies`, matrix operations use `Vec>` throughout. This is bounds-checked but less efficient. | -| No C FFI | PASS | No FFI calls. ESP32 code uses pure Rust types. | -| No `std::mem::transmute` | PASS | None found. | -| No `std::ptr` usage | PASS | None found. | -| Bounds checking on slices | PASS | Uses `.get()`, iterator methods, and Rust's built-in bounds checks. | -| Integer overflow | **CONCERN** | `max_raw_value()` in `adc.rs` casts `(1u32 << resolution_bits) - 1` to `i16`. If `resolution_bits > 15`, this overflows silently. Currently only 12 or 16 are intended, but 16 produces `i16::MAX` wrapping. | - -**Recommendation**: Add a validation check on `resolution_bits` in `AdcConfig` (must be <= 15 for i16 representation, or switch to u16/i32). Consider migrating `Vec>` matrix representations to `ndarray::Array2` for better cache performance and built-in bounds checking. - ---- - -### Data Privacy - -Neural data is among the most sensitive personal data categories. This section covers data handling practices. - -| Check | Status | Notes | -|-------|--------|-------| -| No PII in log messages | **NEEDS AUDIT** | The crate uses `tracing` in workspace dependencies but currently has no `tracing::info!` or `tracing::debug!` calls with data fields. As logging is added, ensure neural data values, subject IDs, and session IDs are never logged at INFO level or below. | -| No neural data in error messages | PASS | Error messages contain structural information (dimensions, indices, version numbers) but not raw signal values or embeddings. | -| `subject_id` handling | **CONCERN** | `EmbeddingMetadata.subject_id` is stored as plaintext `Option`. This is PII that is included in serialized embeddings (serde), HNSW indices, and RVF files. | -| `session_id` handling | **CONCERN** | Same concern as `subject_id`. | -| Memory store encryption | **NOT IMPLEMENTED** | `NeuralMemoryStore` holds embeddings in plaintext `Vec`. No encryption-at-rest. | -| Memory zeroization on drop | **NOT IMPLEMENTED** | Embedding data is not zeroed when dropped. Sensitive neural data persists in deallocated memory. | -| WASM data boundary | STUB | WASM crate is not yet implemented. When implemented, must ensure no neural data is sent to external services without explicit user consent. | -| RVF file privacy | **CONCERN** | `RvfFile` serializes `metadata` as JSON, which may contain `subject_id`. No option to strip or anonymize metadata before export. | - -**Recommendations**: -- Implement a `Redactable` trait for types that may contain PII, providing `redact()` and `anonymize()` methods. -- Use the `zeroize` crate to zero sensitive data on drop for `NeuralEmbedding`, `NeuralMemoryStore`, and `MultiChannelTimeSeries`. -- Add a `strip_pii()` method to `RvfFile` that removes or hashes identifiers before export. -- Document privacy responsibilities in each crate's module documentation. -- For v0.2: Add optional encryption-at-rest for `NeuralMemoryStore` using `ring` or `aes-gcm`. - ---- - -### Network Security (ESP32) - -| Check | Status | Notes | -|-------|--------|-------| -| Node ID authentication | **NOT IMPLEMENTED** | ESP32 crate (`ruv-neural-esp32`) is currently a local ADC reader with no network protocol. When TDM protocol is added, node IDs must be authenticated. | -| CRC32 integrity | **NOT IMPLEMENTED** | No data packet framing or integrity checks exist yet. | -| TLS encryption | **NOT IMPLEMENTED** | v0.1 has no network layer. Planned for v0.2. | -| Packet size limits | **NOT IMPLEMENTED** | No packet protocol exists yet. | -| Buffer overflow prevention | PARTIAL | `AdcReader` uses a fixed-size ring buffer (4096 samples), which prevents unbounded growth. However, `load_buffer` silently truncates data that exceeds buffer size rather than reporting it. | -| DMA configuration | N/A | `dma_enabled` is a configuration flag only; actual DMA is not implemented in std mode. | - -**Recommendations for v0.2 TDM Protocol**: -- Authenticate node IDs using a pre-shared key or challenge-response. -- Add CRC32 or CRC32-C to every data packet. -- Set maximum packet size to 1460 bytes (single WiFi frame MTU). -- Use DTLS or TLS 1.3 for encryption when available. -- Rate-limit incoming packets per node to prevent flooding. -- Validate all fields in received packets before processing. - ---- - -### Supply Chain - -| Check | Status | Notes | -|-------|--------|-------| -| Minimal dependencies | PASS | Core dependencies: `thiserror`, `serde`, `serde_json`, `num-complex`, `rustfft`, `rand`. All are well-maintained, widely-used crates. | -| No proc macros except serde | PASS | Only `serde`'s derive macros and `thiserror`'s derive macro are used. `clap`'s derive is CLI-only. | -| All deps from crates.io | PASS | No git dependencies or path dependencies outside the workspace. | -| Workspace-managed versions | PASS | All dependency versions are declared in `[workspace.dependencies]`. | -| `petgraph` usage | **UNUSED** | Listed in workspace dependencies but not imported by any crate. Remove to reduce supply chain surface. | -| `tokio` usage | **UNUSED** | Listed in workspace dependencies but not imported by any crate. Remove unless async is planned. | -| `ruvector-*` crates | **UNUSED** | Five RuVector crates listed but not imported by any workspace member. Remove unused dependencies. | -| `Cargo.lock` | PRESENT | `Cargo.lock` is committed, ensuring reproducible builds. | - -**Recommendation**: Run `cargo deny check` to audit for known vulnerabilities. Remove unused workspace dependencies (`petgraph`, `tokio`, `ruvector-*` crates) to minimize attack surface. Add `cargo audit` to CI. - ---- - -### Findings from Code Audit - -#### SEC-001: RVF Unbounded Allocation (Severity: Medium) - -**Location**: `ruv-neural-core/src/rvf.rs`, line 193 - -```rust -let mut meta_bytes = vec![0u8; header.metadata_json_len as usize]; -``` - -A crafted RVF file with `metadata_json_len = 0xFFFFFFFF` allocates 4 GB. Similarly, `read_to_end` on line 201 reads unbounded data. - -**Fix**: Add maximum size constants and validate before allocating: -```rust -const MAX_METADATA_LEN: u32 = 16 * 1024 * 1024; // 16 MB -const MAX_PAYLOAD_LEN: usize = 256 * 1024 * 1024; // 256 MB - -if header.metadata_json_len > MAX_METADATA_LEN { - return Err(RuvNeuralError::Serialization( - format!("metadata_json_len {} exceeds maximum {}", header.metadata_json_len, MAX_METADATA_LEN) - )); -} -``` - -#### SEC-002: Missing Sample Rate Validation (Severity: Medium) - -**Location**: `ruv-neural-core/src/signal.rs`, `MultiChannelTimeSeries::new` - -The `sample_rate_hz` parameter is not validated. A value of 0.0 causes division by zero in `duration_s()`. A negative or NaN value causes incorrect spectral analysis throughout the pipeline. - -**Fix**: Add validation in the constructor: -```rust -if sample_rate_hz <= 0.0 || !sample_rate_hz.is_finite() { - return Err(RuvNeuralError::Signal( - format!("sample_rate_hz must be positive and finite, got {}", sample_rate_hz) - )); -} -``` - -#### SEC-003: NaN Propagation in Signal Processing (Severity: Low) - -**Location**: `ruv-neural-signal/src/connectivity.rs`, all functions - -If either input signal contains NaN, the Hilbert transform produces NaN outputs, which propagate silently through PLV, coherence, and all connectivity metrics. The result is a brain graph with NaN edge weights, which causes undefined behavior in Stoer-Wagner (infinite loops or wrong results). - -**Fix**: Add a `validate_signal` helper and call it at entry points: -```rust -fn validate_signal(signal: &[f64]) -> Result<()> { - if signal.iter().any(|x| !x.is_finite()) { - return Err(RuvNeuralError::Signal("Signal contains NaN or Inf values".into())); - } - Ok(()) -} -``` - -#### SEC-004: Integer Overflow in ADC (Severity: Low) - -**Location**: `ruv-neural-esp32/src/adc.rs`, `AdcConfig::max_raw_value` - -```rust -pub fn max_raw_value(&self) -> i16 { - ((1u32 << self.resolution_bits) - 1) as i16 -} -``` - -For `resolution_bits = 16`, this computes `65535 as i16 = -1`, which causes incorrect voltage conversion (division by -1 flips sign). - -**Fix**: Change return type to `u16` or `i32`, or validate `resolution_bits <= 15`. - -#### SEC-005: HNSW Visited Array Allocation (Severity: Low) - -**Location**: `ruv-neural-memory/src/hnsw.rs`, `search_layer`, line 261 - -```rust -let mut visited = vec![false; self.embeddings.len()]; -``` - -This allocates a visited array proportional to the total number of embeddings on every search call. For large indices (100K+ embeddings), this causes unnecessary allocation pressure. More critically, if `entry` is >= `self.embeddings.len()`, the indexing on line 262 panics. - -**Fix**: Use a `HashSet` instead of a boolean array for sparse visitation. Add bounds check on `entry`. - ---- - -## Performance Review - -### Computational Complexity - -| Operation | Complexity | Target Latency | Current Status | -|-----------|-----------|----------------|----------------| -| FFT (1024 points) | O(N log N) | <1 ms | Implemented via `rustfft` (SIMD-optimized).

Meets target for N <= 4096. | -| PLV (channel pair) | O(N) + 2x FFT | <0.5 ms | Calls `hilbert_transform` twice. Meets target for N <= 2048. | -| Coherence (channel pair) | O(N) + 2x FFT | <0.5 ms | Same as PLV. | -| Connectivity matrix (68 regions) | O(N^2 x M) | <10 ms | M = samples per channel, N = 68: 2,278 Hilbert pairs. May exceed target for long windows. | -| Stoer-Wagner mincut (68 nodes) | O(V^3) | <5 ms | 68^3 = ~314K operations. Meets target. | -| Spectral embedding (68 nodes) | O(V^2 x k x iterations) | <3 ms | With k=8, iterations=100: 68^2 x 8 x 100 = ~37M ops. May be tight. | -| Fiedler decomposition | O(V^2 x iterations) | <2 ms | 1000 iterations x 68^2 = ~4.6M ops. Meets target. | -| Cheeger constant (exact, n<=16) | O(2^n x n^2) | <5 ms | Exponential but capped at n=16: 65K x 256 = ~16M ops. Meets target. | -| HNSW insert | O(log N x ef x M) | <1 ms | ef=200, M=16: ~3200 distance computations per insert. Meets target. | -| HNSW search (10K embeddings) | O(log N x ef) | <1 ms | ef=50: ~50-200 distance computations. Meets target. | -| Brute-force NN (10K embeddings) | O(N x d) | <5 ms | d=256, N=10K: 2.56M f64 ops. Acceptable but HNSW preferred. | -| Full pipeline (68 regions) | - | <50 ms | Sum of above stages. Should meet target. | - -### Memory Usage - -| Component | Calculation | Size | -|-----------|------------|------| -| 64-channel x 1000 Hz x 8 bytes x 1s | 64 x 1000 x 8 | 512 KB per second | -| Brain graph adjacency (68 nodes) | 68^2 x 8 bytes | ~37 KB | -| Brain graph adjacency (400 nodes) | 400^2 x 8 bytes | ~1.25 MB | -| Single embedding (256-d) | 256 x 8 bytes | 2 KB | -| Memory store (10K embeddings, 256-d) | 10K x 2 KB | ~20 MB | -| HNSW index (10K, M=16, 256-d) | 10K x (2KB + 16 x 16 bytes) | ~22.5 MB | -| Stoer-Wagner working memory (68 nodes) | 2 x 68^2 x 8 + 68 x vec overhead | ~75 KB | -| Spectral embedder (68 nodes, k=8) | k x 68 x 8 + Laplacian 68^2 x 8 | ~41 KB | -| RVF file in memory | header + metadata + payload | Variable, unbounded (see SEC-001) | - -### Optimization Opportunities - -#### Immediate (v0.1) - -1. **Eliminate redundant Hilbert transforms in connectivity matrix** - - `compute_all_pairs` calls `hilbert_transform` twice per channel pair. - - For 68 channels, this means 68 x 67 = 4,556 Hilbert transforms instead of 68. - - **Fix**: Pre-compute analytic signals for all channels, then compute metrics pairwise. - - **Expected speedup**: ~67x for connectivity matrix computation. - -2. **Replace Vec> with flat Vec for adjacency matrices** - - Current `Vec>` has poor cache locality due to heap-allocated inner Vecs. - - **Fix**: Use `Vec` with manual row-major indexing, or migrate to `ndarray::Array2`. - - **Expected speedup**: 2-4x for matrix-heavy operations (Stoer-Wagner, Laplacian). - -3. **Avoid Vec::remove(0) in eviction** - - `NeuralMemoryStore::evict_oldest` calls `self.embeddings.remove(0)`, which is O(n). - - **Fix**: Use a `VecDeque` or circular buffer. - - **Expected speedup**: O(1) eviction instead of O(n). - -4. **Pre-allocate FFT planner** - - `compute_psd`, `compute_stft`, and `hilbert_transform` each create a new `FftPlanner` per call. - - **Fix**: Cache the planner or use a thread-local planner. - - **Expected speedup**: Eliminates repeated plan computation. - -#### Medium-term (v0.2) - -5. **Rayon for parallel channel processing** - - `compute_all_pairs` iterates channel pairs sequentially. - - **Fix**: Use `rayon::par_iter` for the outer loop. - - **Expected speedup**: Linear with core count for connectivity computation. - -6. **SIMD for distance computations in HNSW** - - Euclidean distance in `HnswIndex::distance` uses scalar iteration. - - **Fix**: Use `packed_simd2` or auto-vectorization hints. - - **Expected speedup**: 4-8x for 256-d vectors on AVX2. - -7. **Sparse graph representation** - - Dense adjacency matrix wastes memory for sparse brain graphs. - - For Schaefer400, storing all 160K entries when only ~10K edges exist is wasteful. - - **Fix**: Use compressed sparse row (CSR) format or `petgraph`'s sparse graph. - -8. **Quantized embeddings for WASM** - - f64 embeddings are unnecessarily precise for browser-based applications. - - **Fix**: Support f32 embeddings in WASM builds, halving memory and transfer size. - -#### Long-term (v0.3+) - -9. **Streaming signal processing** - - Current design loads entire time windows into memory. - - **Fix**: Implement ring-buffer based streaming for real-time operation. - -10. **GPU acceleration for large-scale spectral analysis** - - For Schaefer400 atlas, eigendecomposition of 400x400 matrices benefits from GPU. - - **Fix**: Optional `wgpu` or `vulkano` backend for matrix operations. - -### ESP32 Constraints - -| Resource | Limit | Current Usage | Status | -|----------|-------|---------------|--------| -| SRAM | 520 KB | Ring buffer: 4096 x channels x 2 bytes = 8 KB (1 channel) | OK | -| SRAM (multi-channel) | 520 KB | 4096 x 16 x 2 = 128 KB (16 channels) | **TIGHT** | -| CPU | 240 MHz dual-core | ADC sampling + data transmission | OK for 1 kHz | -| Flash | 4 MB | Binary size with release profile | Needs measurement | -| WiFi throughput | ~1 Mbps sustained | 64 ch x 1000 Hz x 2 bytes = 128 KB/s = 1 Mbps | **AT LIMIT** | - -**Recommendations**: -- Use fixed-point arithmetic (i16 or Q15) instead of f64 on ESP32. -- Implement delta encoding or simple compression for data packets. -- Limit on-device processing to ADC readout and basic quality checks. -- Move all signal processing (FFT, connectivity, graph construction) to the host. -- Profile binary size with `cargo bloat` to ensure it fits in 4 MB flash. -- Consider reducing ring buffer size for multi-channel configurations. -

start; -``` - -### Performance Findings from Code Audit - -#### PERF-001: Redundant Hilbert Transforms (Severity: High) - -**Location**: `ruv-neural-signal/src/connectivity.rs`, `compute_all_pairs` - -Each call to `phase_locking_value`, `coherence`, `imaginary_coherence`, or `amplitude_envelope_correlation` independently calls `hilbert_transform` on both input signals.

This crate turns sensing from *RF-happens → observe* into +//! *RuView-controls-RF → observe the response → optimize the next measurement*. +//! It models the **control loop** ADR-280 deferred (ADR-280 built the governed +//! actuation surface but left information-gain-driven closed-loop control as a +//! roadmap item): read the current per-zone uncertainty and the last response, +//! and propose the controllable measurement configuration expected to reduce +//! that uncertainty most. +//! +//! It is a **simulation / planning model**, not a driver. Constructing a +//! [`ControlAction`] or a [`MeasurementPlan`] drives **no** radio, changes no +//! pairing state, and emits **no** RF — the loop *emits a plan*, and a fielded +//! caller submits every proposal through the ADR-280 fail-closed +//! admission/actuation surface. A twin predicts; it does not measure: no +//! `MEASURED`, accuracy, or traffic-reduction claim is made or implied. Every +//! exploration figure this crate produces is `SYNTHETIC` (CLAUDE.md honesty +//! discipline; ADR-309 §3). +//! +//! ## The four ADR-300 non-negotiable rules, as they bind this crate +//! +//! 1. **UNKNOWN is first-class, never an error.** A [`LastResponse::Unknown`] +//! is not zero uncertainty and not an error: the policy *widens* exploration +//! ([`ControllerConfig::unknown_widen`]) rather than committing to a narrow +//! configuration on a target it cannot currently resolve. A non-finite +//! uncertainty becomes maximal uncertainty, never a silent zero. +//! [`ClosedLoopController::step`] is total — no input panics. +//! 2. **Certificates bind cryptographically.** Out of scope here; a proposal +//! names an already-authenticated ADR-306 +//! [`ZoneId`](ruview_ontology::ZoneId), and a fielded loop step is admitted +//! through the ADR-280 governed path before any actuation. +//! 3. **One canonical semantics downstream.** The loop reuses the canonical +//! [`ZoneId`](ruview_ontology::ZoneId), +//! [`EvidenceLevel`](ruview_ontology::EvidenceLevel), and +//! [`SemanticProvenance`](ruview_ontology::SemanticProvenance) rather than +//! reinventing per-crate identity/evidence shapes. It shares the *notion* of +//! expected gain with ADR-314 but defines its own [`ControlAction`] +//! vocabulary and does **not** depend on `ruview-infogain`, so the two crates +//! build in parallel. +//! 4. **Honest evidence.** Every proposal is stamped [`EvidenceLevel::L1`] +//! (heuristic/synthetic) with an explicit synthetic provenance; the +//! exploration scalar is a modelled magnitude, not a measured gain. When no +//! axis is controllable the controller returns [`PassiveReason::NoControllableAxes`] +//! rather than fabricating a gain estimate. +//! +//! ## The loop, in one call +//! +//! ``` +//! use ruview_active::*; +//! use ruview_ontology::ZoneId; +//! +//! // A deployment that can vary channel width and antenna aperture. +//! let cap = ControlCapability::new( +//! vec![Channel::new(Band::Ghz5, 36).unwrap()], +//! vec![Bandwidth::Bw20, Bandwidth::Bw160], +//! vec![], +//! vec![ +//!

Cognitum OAuth access-token verification (ADR-271). +//! +//! The accept-rule is ported from `meta-llm/src/auth/oauthBearer.ts` (ADR-045), +//! the only other resource-server-side verifier of these tokens in the org. +//! Divergence from it would be a bug, not a preference — a token meta-llm +//! rejects must not be one RuView accepts. +//! +//! ## The trust chain, narrowly +//! +//! 1. Only identity's ES256 key — fetched from the published JWKS by `kid` — +//! can sign an accepted token. No shared secret, no static PEM to leak. +//! 2. **The algorithm is fixed to ES256 by this code.** The token header's `alg` +//! is only ever *compared against* that allowlist, never used to *select* an +//! algorithm. That is what makes `alg: none` and RSA-substitution +//! non-starters rather than things we defend against case by case. +//! 3. Signature math is `jsonwebtoken`'s. This module owns claim policy only. +//! +//! ## Why `setup` and `workload` tokens are refused outright +//! +//! Identity also issues long-lived *setup* (365-day) and *workload* credentials. +//! Their revocation lives in identity's `oauth_setup_tokens` table, and RuView — +//! like meta-llm — has **no database and no way to check it**. A 15-minute +//! access token needs no revocation round-trip because it expires faster than +//! any realistic revocation propagates; a 365-day one does. Accepting one would +//! mean honouring a credential that may already have been revoked, so we don't. +//! +//! ## There is no `aud` claim, and no `iss` claim either +//! +//! Verified against real production tokens: the claim set is exactly +//! `typ, sub, account_id, org_id, workspace_id, client_id, scope, family_id, +//! jti, iat, exp, setup, workload`. No audience. No issuer. +//! +//! **What binds a token to its issuer, then?** The JWKS. We accept only +//! signatures made by a key served from the configured `jwks_uri`, so +//! possession of a valid signature *is* proof of issuer. Adding an `iss` claim +//! check on top would not strengthen that — and requiring a claim identity does +//! not emit rejects every genuine token, which is exactly what an earlier +//! revision of this module did. +//! +//! **`client_id` is Cognitum's stand-in for `aud`.** `cognitum-one/freetokens` +//! (live) documents the contract — *"Cognitum access tokens intentionally use +//! custom `client_id` rather than a registered JWT `aud` claim"* — and rejects +//! any token whose `client_id` is not its own. This verifier does the same via +//! [`VerifierConfig::allowed_client_ids`]. +//! +//! An earlier revision treated `client_id` as unusable because clients borrow +//! each other's registrations (musica shipped as `meta-proxy` while its own was +//! pending) and relied on scope alone. That was reasoning from a transitional +//! state: RuView has its own registered client, and accepting a token minted for +//! any Cognitum product is a weaker position than the platform intends. +//! +//!

This crate is a *phase-3, research-forward primitive*: a step beyond +//! discriminative classifiers toward a **generative spatial model**. A +//! classifier maps measurements to a label; it cannot say *"the observation is +//! better explained by absence"* or *"one occupant explains this better than +//! two,"* because it has no model of what a measurement *should* look like under +//! a hypothesized world state. This layer supplies that missing piece: given an +//! observed link-measurement set and the ADR-315 digital RF twin as the +//! generative forward model, it scores a small set of scene +//! [`Hypothesis`](Hypothesis) — including the **null hypothesis** (nobody +//! present) — and returns the maximum-likelihood explanation with a **margin**, +//! or a first-class `UNKNOWN` when the hypotheses are near-indistinguishable. +//! +//! It is a **consumer** of the twin, never a second simulator (ADR-313 option 3, +//! rejecting option 2): the ADR-315 twin supplies each link's baseline expected +//! distribution (geometry + propagation), and this layer applies a **documented +//! SYNTHETIC occupant-attenuation model** — a hypothesized occupant attenuates +//! any link whose line of sight passes near it. Hypotheses are drawn from the +//! ADR-311 fused world state and its neighbourhood and are expressed over the +//! canonical ADR-306 [`SpaceId`](ruview_ontology::SpaceId), so a counterfactual +//! result is a governed spatial statement, not an opaque score (ADR-300 rule 3). +//! +//! ## Honesty and evidence discipline (CLAUDE.md, ADR-313) +//! +//! Every likelihood is a **model-relative** score under a twin whose +//! distributions are a simulation at evidence level `L0`, labelled `SYNTHETIC`. +//! A twin *predicts*; it does not *measure*. A counterfactual verdict inherits +//! the `L0` level of its weakest input and is **never** presented as +//! camera-grade ground truth. This crate makes **no** hardware, `MEASURED`, or +//! accuracy claim, and asserts **no** discrimination-accuracy number (e.g. it +//! does not claim to "distinguish one occupant from two"); any such number would +//! require the mean-pose-style baseline discipline, a leakage-free held-out +//! split, and a reproducer before it could be tagged `MEASURED`. +//! +//! ## UNKNOWN is a first-class output (ADR-300 rule 1, ADR-313 §3) +//! +//! The layer never forces a label. The best explanation resolves to a +//! first-class [`BestExplanation::Unknown`] when the top two hypotheses are +//! near-indistinguishable (margin below threshold), when **no** hypothesis +//! explains the observation well (best mean per-link log-likelihood below a +//! floor — routed to the ADR-302 `UNKNOWN` verdict), when no hypotheses are +//! supplied, or when no observed link is evaluable against the twin. UNKNOWN is +//! a value, never an error, a panic, or a confident default. +//! +//! ## Determinism +//! +//! Everything is a pure, deterministic function of its inputs: no I/O, no clock, +//! and no randomness. Synthetic scenes vary only by the twin's explicit +//! [`seed`](ruview_twin::DeploymentDescription::seed); malformed input abstains +//!

"MLflow for physical sensing." Where an experiment tracker overwrites +//! yesterday's number, this crate is an **append-only** record of how a model +//! actually performs, keyed per deployment context +//! `(room, device, subject-class, model-version)` and carrying, per record, +//! the ADR-304 metrics (moving/stationary recall, false-positive rate, drift, +//! predictive uncertainty, calibration age, sample count) plus exactly one +//!

[`EvidenceLevel`] ladder mirrors ADR-282 (`frame::EvidenceLevel`) but is +//! defined locally so the ledger never pulls in the frame crate. +//! - **Deterministic**: no wall-clock and no randomness. Record time is +//! injected by the caller; the ledger assigns a monotonic append sequence. +//! - **Honest by construction**: +//! - A record's [`EvidenceLevel`] is fixed by its *provenance* at write time +//! ([`EvidenceRecord::synthetic`] is `L0` and cannot be raised — there is +//! no `set_level`). This is the ADR-282/288/290 "no upgrade" rule. +//! - Records are **append-only**: [`EvidenceLedger::append`] consumes a +//! record by value and nothing hands back a mutable reference.

A summary's evidence level is the **floor** (minimum) of the +//! levels present in the slice — a slice can never report a level above the +//! weakest record it contains. +//! - An empty context returns [`SummaryEvidence::NoEvidence`], distinct from a +//! present-but-zero-accuracy summary — downstream (ADR-318) must treat +//!

synthetic input is +//! `Synthetic`/L0 by construction and cannot be raised. + +#![forbid(unsafe_code)] +#![warn(missing_docs)] + +mod agreement; +mod align; +mod error; +mod model; +mod scope; +mod series;

This crate consumes the canonical ontology (ADR-306) — its output is an +//! ontology `Observation` bound to a `Sensor` — and its observations feed real +//! sensor fusion (ADR-311). It is a **pure abstraction**: no I/O, no async, no +//! inference, no accuracy claim. A passing trait test proves the abstraction, +//! not a fielded device; hardware support for any modality stays CLAIMED until +//! demonstrated on real silicon with captured evidence (CLAUDE.md). +//! +//! ## The four ADR-300 non-negotiable rules, as they bind this crate +//! +//! 1. **UNKNOWN is first-class, never an error.** [`SensorHal::normalize`] is +//! infallible: malformed / out-of-bounds raw input yields an UNKNOWN-flagged +//! ([`Uncertainty::degraded`]) observation, never a panic or `Err`. +//! 2. **Certificates bind cryptographically.** Out of scope for the HAL, but a +//! device is authenticated as an ADR-305 `Sensor` (the descriptor's +//! `sensor_id`) before its observations are trusted. +//! 3. **One canonical semantics downstream.** The HAL reuses the ontology's +//! `Observation`, `Sensor`, `EvidenceLevel`, and `SemanticProvenance` rather +//! than reinventing per-crate shapes; [`HalObservation`] *wraps* the +//! canonical observation and delegates its evidence/provenance accessors. +//! 4. **Honest evidence.** A camera-derived and a CSI-derived observation are +//! the same type with different provenance; neither is lifted to the other's +//! grade. The reference adapters are SYNTHETIC / [`EvidenceLevel::L0`] and +//! cannot alias to a measured level. +//! +//! ## Core shapes +//! +//! - [`Modality`] — the phenomenon class (closed variants + `Custom`). +//! - [`SensorDescriptor`] / [`SamplingSpec`] — canonical device description with +//! ontology `SensorId`, capability tags, and native sampling/units metadata. +//! - [`HalObservation`] — wraps [`Observation`](ruview_ontology::Observation) +//! with a [`Modality`] and per-observation [`Uncertainty`]; delegates +//! `EvidenceLevel` / `SemanticProvenance`. +//! - [`SensorHal`] — the extension-point trait: `describe` + `normalize`. +//! - [`SyntheticCsiAdapter`], [`SyntheticImuAdapter`] — deterministic reference +//! adapters (one RF, one non-RF), labelled SYNTHETIC / L0. +//! +//! ## Mapping existing adapters onto the trait (docs only) +//! +//! This crate does not rewrite the existing producers; it is the trait they are +//! re-expressed as. RF modalities reuse the ADR-279 per-device latent adapters +//! wholesale — the HAL adds the non-RF and ranging modalities under the same +//! trait. Each row is the `SensorHal` an existing producer implements when it +//! is brought under the abstraction: +//! +//! | Existing producer | Source ADR | `Modality` | `SensorHal::Raw` (native frame) | Notes | +//! |---|---|---|---|---| +//! | ESP32-S3/C6 CSI node | ADR-279 / firmware | [`Modality::Csi`] | `RfFrameV2` (subcarrier complex) | Reuses the ADR-279 native-frame → shared-latent adapter; the HAL only lifts the latent into an `Observation`. | +//! | Nexmon CSI | ADR-279 | [`Modality::Csi`] | `RfFrameV2` | Per-device adapter into the shared latent; same trait, different native layout. | +//! | FeitCSI / Intel / Atheros / Realtek | ADR-279 | [`Modality::Csi`] | `RfFrameV2` | Same shared-latent path; bandwidth/antenna structure kept native, not canonicalized. | +//! | 802.11bf sensing | ADR-310 (phase 2) | [`Modality::Ieee80211bf`] | native 11bf measurement frame | Enters under the same trait as it lands. | +//! | mmWave radar | ADR-063 | [`Modality::Mmwave`] | range-doppler / point frame | The ADR-063 fusion producer becomes a `SensorHal` implementation. | +//! | Multistatic WiFi | ADR-029 | [`Modality::Csi`] | multi-link `RfFrameV2` set | Multiple links, one authenticated `Sensor`, one `Observation`. | +//! +//! Non-RF modalities (camera, lidar, acoustic) enter the same governed plane +//! with the same provenance and privacy discipline — a camera is not a +//! privacy-free shortcut; it inherits ADR-277 governance and carries its own +//! honest evidence level. The two synthetic reference adapters in this crate +//!

This crate models *which radios/modalities to spend the next sampling budget +//! on* by value of information. It is a **simulation/model scaffold**: every +//! informativeness estimate is a model prediction and every cost is a modelled +//! magnitude. Nothing here measures hardware, and **no** `MEASURED`, accuracy, +//! or energy/latency/throughput claim is made or implied — a twin predicts, it +//! does not measure (CLAUDE.md honesty discipline; ADR-314 asserts no +//! efficiency number). Any figure produced by this crate is `SYNTHETIC`. +//! +//! ## What it does +//! +//! With many sensors, processing every stream at full rate wastes the three +//! scarce edge resources — compute, energy, bandwidth. This scheduler assigns +//! each candidate action a value +//! +//! ```text +//! Value(sensor) ≈ expected_uncertainty_reduction / (compute + energy + bandwidth) +//! ``` +//! +//! and spends the budget on the highest-value actions, so the edge samples the +//! most informative radios first. In a fielded system the numerator comes from +//! the ADR-315 RF-twin forward model against the ADR-311 fused covariance and +//! the denominator from ADR-320 HAL cost descriptors; this crate takes both as +//! caller-supplied inputs and stays a pure allocator. +//! +//! ## The four ADR-300 non-negotiable rules, as they bind this crate +//! +//! 1. **UNKNOWN is first-class, never an error.** A candidate whose +//! informativeness the model cannot predict is +//! [`ExpectedReduction::Unknown`] — handled by an explicit +//! [`UnknownPolicy`] (probe or defer), **never** silently treated as zero. A +//! malformed cost is UNKNOWN cost and defers the candidate rather than +//! panicking or guessing. [`Scheduler::plan`] is total: no input panics. +//! 2. **Certificates bind cryptographically.** Out of scope here; a candidate +//! names an already-authenticated ADR-305 [`SensorId`](ruview_ontology::SensorId). +//! 3. **One canonical semantics downstream.** Candidates reuse the canonical +//! [`SensorId`](ruview_ontology::SensorId) and HAL [`Modality`](ruview_hal::Modality) +//! rather than reinventing per-crate identity/modality shapes. +//! 4. **Honest evidence.** A scheduling decision is a resource choice, not a +//! sensing claim; the plan records which sensors were skipped so ADR-302 can +//! raise `UNKNOWN` for an under-sampled zone rather than reporting a stale +//! estimate as current. +//! +//! ## Purity +//! +//! [`Scheduler::plan`] has **no** scheduling side effects: it starts no +//! sampling and touches no hardware — it returns a [`SchedulePlan`]. ADR-309 +//! active sensing chooses the probe on each selected sensor; ADR-311 fusion +//! incorporates the result. It is deterministic (no wall clock, no randomness; +//! synthetic scenes vary only by explicit caller-supplied parameters) and +//! bounded in allocation. +//! +//! ## Example +//! +//! ``` +//! use ruview_infogain::*; +//! use ruview_hal::Modality; +//! use ruview_ontology::SensorId; +//! +//! let candidates = vec![ +//!

This crate is a *research-forward primitive*: it learns the **normal physics +//! of a location** so anomalies surface as *deviations from a learned baseline +//! of normality* — without training a detector for every anomaly class. It is a +//! **model**, not a sensor. It predicts what is normal for a place and time and +//! flags a statistically significant delta; it never *measures* anything, and it +//! asserts **no** detection-accuracy, false-positive, or health/safety number +//! (ADR-282 bounded-claims discipline, ADR-312 evidence discipline, CLAUDE.md +//! honesty rule). A flagged deviation is a *candidate change to corroborate*, +//! never a confident detection and never a diagnosis. +//! +//! Following ADR-300 rule 1, *insufficient information* is a first-class value +//! ([`Assessment::Unknown`]), never an error and never a false positive: no +//! anomaly is ever flagged before a baseline exists. +//! +//! ## What "normal" is learned over (ADR-312 §1) +//! +//! Per ADR-306 [`ZoneId`], a [`ZoneBaseline`] accumulates: +//! +//! - **Occupancy periodicity** — a distribution of occupancy by UTC hour-of-day +//! (the "bedroom usually occupied certain hours" case). +//! - **RF-propagation signature** — a per-link learned normal, *anchored on the +//! twin's expected distributions* ([`SpatialMemory::seed_zone_propagation_from_twin`]) +//! and refined online (the "chair moved" / "propagation changed" / "new +//! reflector" cases, which all surface as a per-link RSSI delta). +//! - **Coarse modality signatures** — per-channel learned normal (the "machine's +//! vibration signature changed" case). +//! +//! Each baseline updates **online** with a documented forgetting factor +//! ([`crate::stat`]); slow legitimate drift is absorbed into the baseline while +//! an abrupt change deviates from it. Every baseline carries the **floor** +//! evidence level of the observations it was learned from and is never presented +//! above them (ADR-282 no-upgrade). +//! +//! ## Anomaly = deviation from learned normal (ADR-312 §3) +//! +//! [`SpatialMemory::observe`] scores a live [`ZoneObservation`] against the +//! applicable learned baseline (matched by zone and hour), returns an +//! [`ObserveOutcome`] of per-channel [`Assessment`]s, and emits an +//! [`AnomalyEvent`] for each channel whose deviation meets the significance +//! gate. Anomalies project to append-only [`ruview_evidence`] records with +//! provenance ([`AnomalyEvent::to_evidence_record`]). +//! +//! ## The four ADR-300 non-negotiable rules, as they bind this crate +//! +//! 1. **UNKNOWN is first-class, never an error.** A channel with fewer than +//! `min_history` updates is [`Assessment::Unknown`]; `observe` is total and +//! never panics on malformed input (it returns a typed [`MemoryError`]). +//! 2. **Certificates bind cryptographically.** Out of scope here; a baseline is +//! keyed by an already-authenticated ADR-306 [`ZoneId`] and its evidence +//! level is the floor of its source observations. +//! 3. **One canonical semantics.** The memory reuses the canonical +//! [`ZoneId`]/[`EvidenceLevel`]/[`SemanticProvenance`] vocabulary, the twin's +//! [`LinkId`]/[`ObservationSet`]/[`ExpectedDistribution`], and the +//! [`ruview_evidence`] ledger, rather than reinventing per-crate shapes. +//! 4. **Honest evidence.** Every emitted record is **synthetic** (forced L0); +//! the deviation is carried as `drift` and its significance as `uncertainty`. +//! No accuracy rate is fabricated. +//! +//! ## Determinism +//! +//! Everything is deterministic: injected time (no wall-clock), no randomness +//! (synthetic scenes vary only by the twin's explicit seed), fixed iteration +//! order, and bounded allocation.

([`ruview_attest::PayloadHash`]) — no separate hash primitive is added. +//! - **ADR-295** contributes [`SourceState`]: a `Synthetic` root can never +//! present as `LiveVerified`, and it caps the chain's effective evidence +//! level. +//! - **ADR-302** contributes [`DomainState`] (the `KNOWN → DEGRADED → UNKNOWN` +//! staleness guard): a low-confidence or out-of-distribution inference is +//! recorded as such, never silently promoted. +//! - **ADR-321** will attach the real terminal [`PolicyDecision`]; here it is a +//! faithfully-typed placeholder for the governed action taken (or withheld). +//! +//! ## Honesty discipline (ADR-300 rule 1 / CLAUDE.md) +//! +//! [`Confidence::Unknown`] is a first-class value, never an error. A missing +//! corroboration is recorded as [`Corroboration::None`], never fabricated. The +//! chain's *effective* evidence level is the **minimum** across its stages, so +//! the chain can never claim more than its weakest link. +//! +//! ### Evidence grade +//! +//! Like `ruview-attest`, any guarantee exercised by this crate's tests is +//! **SYNTHETIC / L0** — the fixtures are constructed in code, never captured +//! from silicon.

Signed, versioned, invalidatable room-fingerprint certificate (ADR-301). +//! +//! ADR-301 is primitive 1 of the perception-substrate program (ADR-300) and the +//! first brick of its "certificate spine".

Nothing here re-derives room state. The [`RoomFingerprint`] is a bounded, +//! fixed-length statistical summary *reused* from the existing calibration types +//! — the [`SpecialistBank`](crate::bank::SpecialistBank)'s empty-vs-occupied +//! presence separation (ADR-135 baseline / ADR-151) and its transceiver +//! [`GeometryEmbedding`](crate::geometry_embedding::GeometryEmbedding) +//! (ADR-152).

A certificate produced from generated CSI is [`EvidenceLevel::L0Synthetic`] +//! by construction; [`CalibrationCertificate::mint`] **rejects** labelling a +//! synthetic characterization as measured, and rejects an automatic +//!

The intended API surface is documented below. - -## Planned Features - -- **Dual backend** -- PostgreSQL for production deployments, SQLite for single-node and embedded - use. Selectable at compile time via feature flags. -- **Redis caching** -- Connection-pooled Redis for low-latency pose estimate lookups, session - state, and pub/sub event distribution. -- **Migrations** -- Embedded SQL migrations managed by SQLx, applied automatically on startup. -- **Repository pattern** -- Typed repository structs (`PoseRepository`, `SessionRepository`, - `AlertRepository`) implementing the core `DataStore` trait. -- **Connection pooling** -- Configurable pool sizes via `sqlx::PgPool` / `sqlx::SqlitePool`. -- **Transaction support** -- Scoped transactions for multi-table writes (e.g., survivor detection - plus alert creation). -- **Time-series optimisation** -- Partitioned tables and retention policies for high-frequency CSI - frame storage. - -### Planned feature flags - -| Flag | Default | Description | -|------------|---------|-------------| -| `postgres` | no | Enable PostgreSQL backend | -| `sqlite` | yes | Enable SQLite backend | -| `redis` | no | Enable Redis caching layer | - -## Quick Start - -```rust -// Intended usage (not yet implemented) -use wifi_densepose_db::{Database, PoseRepository}; -use wifi_densepose_core::PoseEstimate; - -#[tokio::main] -async fn main() -> anyhow::Result<()> { - let db = Database::connect("sqlite://data/wifi-densepose.db").await?; - db.run_migrations().await?; - - let repo = PoseRepository::new(db.pool()); - - // Store a pose estimate - repo.insert(&pose_estimate).await?; - - // Query recent poses - let recent = repo.find_recent(10).await?; - println!("Last 10 poses: {:?}", recent); - - Ok(()) -} -``` - -## Planned Schema - -```sql --- Core tables -CREATE TABLE csi_frames ( - id UUID PRIMARY KEY, - session_id UUID NOT NULL, - timestamp TIMESTAMPTZ NOT NULL, - subcarriers BYTEA NOT NULL, - antenna_id INTEGER NOT NULL -); - -CREATE TABLE pose_estimates ( - id UUID PRIMARY KEY, - frame_id UUID REFERENCES csi_frames(id), - timestamp TIMESTAMPTZ NOT NULL, - keypoints JSONB NOT NULL, - confidence REAL NOT NULL -); - -CREATE TABLE scan_sessions ( - id UUID PRIMARY KEY, - started_at TIMESTAMPTZ NOT NULL, - ended_at TIMESTAMPTZ, - config JSONB NOT NULL -); -``` - -## Related Crates - -| Crate | Role | -|-------|------| -| [`wifi-densepose-core`](../wifi-densepose-core) | `DataStore` trait definition | -| [`wifi-densepose-config`](../wifi-densepose-config) | Database connection configuration | -| [`wifi-densepose-api`](../wifi-densepose-api) | REST API (consumer) | -| [`wifi-densepose-mat`](../wifi-densepose-mat) | Disaster detection (consumer) | -| [`wifi-densepose-signal`](../wifi-densepose-signal) | CSI signal processing | - -## License - -MIT OR Apache-2.0 diff --git a/v2/crates/wifi-densepose-db/src/lib.rs b/v2/crates/wifi-densepose-db/src/lib.rs deleted file mode 100644 index eaa4c7c934..0000000000 --- a/v2/crates/wifi-densepose-db/src/lib.rs +++ /dev/null @@ -1 +0,0 @@ -//!

Anyone within radio range can passively capture +those reports and, from the tiny stable details in them, **tell individual +people apart by their radio "fingerprint"** — through walls, with no camera, no +app, and nothing you have to be carrying. Published research re-identifies +individuals, counts occupancy through walls, and even reads activity this way, +and the 2025 sensing standard (802.11bf) added the capability but **no privacy +protection**. Because the attacker only listens, you get no indication it is +happening. + +**The defense — scramble the fingerprint, keep the link.** WiFi Veil adds a secret, +**per-session "twist"** to your own outgoing feedback, built from the same +rotation math (Givens rotations) the report already uses: + +- Your **own router shares the key** and undoes the twist instantly, so it + decodes normally — **your WiFi keeps ~98% of its speed.** +- An **outside listener sees a *different* twist every session** and cannot + average many captures back into one stable fingerprint. Its guess of *who is + in the room* **collapses to chance** — no better than a random guess among the + possible people. +- The twist only **reshapes your own, standards-legal signal** — it preserves + the signal's energy exactly (`energy in = energy out`), so it is **compliant, + never jamming.** It never floods the air or blocks anyone else. + +**What it does *not* do (kept honest).** WiFi Veil defends against a *third-party +sniffer*, not the access point you are connected to (that party holds the key — +protecting against a malicious AP is BFLD's detection job). It targets identity +re-identification; coarse motion obfuscation is future work. And every figure in +this crate is **SYNTHETIC / evidence-level L0** — it describes the reference +model and is *not* a measured guarantee on real hardware until validated with a +captured hardware log. + +> **In one line:** it makes the room's WiFi stop leaking *who you are* to +> outside listeners, while your network keeps working and without breaking any +> radio rules. + +## The idea + +Identity leaks through the **fine** cross-subcarrier phase structure of a +compressed beamforming report; data throughput rides the **dominant** beam +direction.

This is where a re-identification attacker's signal lives: the +//! literature (BFId, CCS 2025) shows the *stable* fine structure re-IDs +//! people. Communication barely uses it. +//! +//! Each identity owns a fixed, near-orthogonal signature vector in the fine +//! block. A session observation is `signature + environmental nuisance`; the +//! comm block is fresh per session.

How this protects you

plain language
+
+
+ + The threat +

Your Wi-Fi constantly sends the router fine signal details — in the clear. A stranger nearby can capture them and recognise individual people by their radio "fingerprint": through walls, with no camera, and nothing on you.

+
+
+ + The shield +

WiFi Veil scrambles that fingerprint on every report with a secret twist only your own router can undo. An outside listener sees a different scramble each time and can't tie it to a person — their guess of "who's here" drops to pure chance.

+
+
+ + Kept honest +

It shapes only your own signal — it never jams, and your Wi-Fi speed stays ~98%. It stops outside snoops, not the router you connect to. Figures here are simulated (L0), pending real-hardware tests.

This is the production fusion path exercised once per TDM cycle. +//! +//! 2. **`embedding_extract`** — an isolated A/B of the embedding-marshalling step +//! that finding 4 fixed: the OLD code cloned every viewpoint embedding +//! *twice* (once into `extracted`, once into `embeddings`); the NEW code +//! clones once (out of the borrowed `viewpoints`) and then *moves* into the +//! attention input. The `before_double_clone` / `after_single_clone` benches +//! measure exactly that difference so the perf claim is MEASURED, not asserted. +//! +//!

RaBitQ **unbiased distance estimator** — the real Gao & Long (SIGMOD 2024) +//! contribution, on top of the Pass-2 rotation ([`crate::rotation`]). +//! +//! ## Why this exists (ADR-156 Milestone-2) +//! +//! Pass-1 ([`crate::sketch`]) and Pass-2 ([`crate::rotation`]) use only the +//! **sign** of each rotated coordinate and rank candidates by **Hamming / +//! bit distance** — a coarse, monotone-but-lossy proxy for the true angle. +//! ADR-156 §10 measured that sign-only Pass-2 leaves strict-K +//! (`candidate_k == K`) top-K coverage at **~46%**, well below the ADR-084 +//! **≥90%** bar, and only clears 90% with ~3× over-fetch. +//! +//! RaBitQ's *actual* algorithmic contribution is not the sign bits — it is an +//! **unbiased estimator of the inner product / squared distance** recovered +//! from the 1-bit code **plus a few bytes of per-vector side information**. +//! That estimate is far sharper than the raw Hamming proxy, so it can +//! **rerank** the candidate set and (the question this module measures) close +//! the strict-K coverage gap. +//! +//! ## The estimator (paper formula + our simplification, stated honestly) +//! +//! Notation follows the paper. Let `P` be the Pass-2 orthogonal rotation +//! ([`crate::Rotation`], `R = H·D`). For a data vector `o_raw` and a query +//! `q_raw`: +//! +//! 1. **Centroid.** The paper centres each vector on its (per-cluster) +//! centroid `c`: residual `o_r = o_raw − c`. **We use a zero / global +//! centroid `c = 0`** (`o_r = o_raw`). This is an explicit simplification +//! (no IVF/k-means cluster structure in the current sketch path) — it costs +//! accuracy when the data is far off-origin, and we document it rather than +//! hide it. With `c = 0`, the residual *is* the raw vector. +//! +//! 2. **Unit residual + 1-bit code.** `o = o_r / ‖o_r‖`. Rotate: +//! `o' = P·o`. The 1-bit code is `x̄_i = sign(o'_i) · (1/√D)`, so `x̄` +//! is a **unit vector** in `{±1/√D}^D` (the corner of the hypercube nearest +//! `o'`). `D` is the rotation's padded dimension (`next_pow2(dim)`), because +//! the FHT operates on the padded length and `x̄` is unit over that length. +//! +//! 3. **Per-vector side information** (the "few bytes"): we store, per sketch, +//! - `residual_norm = ‖o_r‖` (an `f32`), and +//! - `x_dot_o = ⟨x̄, o'⟩` (an `f32`), the cosine between the code and the +//! rotated unit residual. This is the quantity the paper calls `⟨x̄, o⟩` +//! (after rotation); it lies in `(0, 1]` and is `1` only when `o'` +//! already sits exactly on a hypercube corner. +//! +//! That is **8 bytes/vector** of side info (2× `f32`). +//! +//! 4. **Query-time estimate.** Rotate the query residual: `q' = P·q_r`. The +//! **unbiased estimator of `⟨o', q'⟩`** (equivalently `⟨o, q_r⟩`, since `P` +//! is orthogonal) is +//! +//! ```text +//! ⟨o', q'⟩ ≈ ⟨x̄, q'⟩ / ⟨x̄, o'⟩ = ⟨x̄, q'⟩ / x_dot_o +//! ``` +//! +//! This is RaBitQ Eq. (in the paper, the estimator ` ≈ `): +//! the random rotation makes the quantization error of `x̄` (relative to +//! `o'`) orthogonal **in expectation** to `q'`, so dividing the measured +//! `⟨x̄, q'⟩` by `x_dot_o` is **unbiased** for `⟨o', q'⟩`, with the paper's +//! `O(1/√D)` error bound. The only per-candidate cost is one length-`D` +//! dot product `⟨x̄, q'⟩` — which, because `x̄ ∈ {±1/√D}`, is just a signed +//! sum of the query coordinates (`±` chosen by the stored sign bits), +//! i.e. as cheap as the Hamming proxy plus one multiply. +//! +//! 5. **Inner product and squared distance.** Un-normalize: +//! `⟨o_r, q_r⟩ = ‖o_r‖ · ⟨o, q_r⟩`. Then +//! +//! ```text +//! ‖q_r − o_r‖² = ‖q_r‖² + ‖o_r‖² − 2·⟨o_r, q_r⟩ +//! ``` +//! +//! For **ranking** a candidate set against one fixed query, `‖q_r‖²` is a +//! per-query constant and can be dropped; we keep it in +//! [`DistanceEstimator::estimate_sq_distance`] so the value is a genuine +//! distance estimate (used by the unbiasedness test), and expose the +//! cheaper ranking key separately. +//! +//! ## What is unbiased, and what we measure +//! +//! The estimator of `⟨o', q'⟩` is unbiased over the random rotation. We pin +//! that on a small hand-checkable fixture (`estimator_unbiased_on_fixture`): +//! averaging the estimate over many random rotation seeds converges to the true +//! inner product within tolerance. We then measure whether **reranking the +//! candidate set by this estimate** closes the strict-K coverage gap that the +//! sign-only Pass-2 left at ~46% — reported honestly in ADR-156 §10 / §11 +//! whether it clears 90% or not. +//! +//! ## Backward compatibility +//! +//! This module is **purely additive**. It introduces an *extended* sketch type +//! ([`EstimatorSketch`]) and bank ([`EstimatorBank`]) that carry the side info; +//! the Pass-1 [`crate::Sketch`] / Pass-2 [`crate::SketchBank`] paths and the +//! [`crate::WireSketch`] wire format are **untouched**.

[SymphonyQG (SIGMOD 2025)](../../../../../docs/adr/ADR-261-ruvector-graph-ann-index.md) +//! unifies **quantization with graph traversal**: instead of computing the full +//! float distance at every node the beam search visits (the cost that dominates +//! float HNSW — one `O(d)` float dot/diff per visited node), it scores traversal +//! candidates with a **cheap quantized distance** and only computes the exact +//! float distance for the *final* candidate set, which it **reranks**. The bet: +//! the quantized score is cheap enough — and accurate enough to keep the beam on +//! the right path — that you visit roughly as many nodes but pay far less per +//! node, and recover the small recall loss with a final exact rerank. Source +//! reports **3.5–17× QPS over HNSW at equal recall**. +//! +//! # Our implementation (honest scope) +//! +//!

The *only* variable between the +//! float and quantized search is **how a candidate is scored during traversal**, +//! so any QPS/recall difference is attributable to the quantization, not to a +//! different graph. +//! - **Quantized score = `b`-bit code over the RaBitQ Pass-2 rotated coordinates** +//! ([`crate::rotation`] + the multi-bit scalar quantizer mirrored from +//! [ADR-156 §10](../../../../../docs/adr/ADR-156-ruvector-fusion-beyond-sota.md)'s +//! `coverage::measure_multibit`). Each node stores a `b`-bit-per-dimension code +//! over the padded rotation length `D = next_pow2(dim)`. During traversal we +//! compare query-code vs node-code by the **L1 distance over the per-dim +//! codes** — a few machine words of integer work, no per-dimension float work. +//! For `b == 1` the codes are `{0, 1}` and the L1 distance is **exactly the +//! 1-bit Hamming distance** of the original ADR-261 construction, so `b == 1` +//! is fully backward-compatible. +//! - **Exact float rerank** of the final beam: the top `rerank` candidates by +//! code-L1 are re-scored with the true float metric and the best `k` returned. +//! +//!

Opt-in bearer-token auth for the sensing-server HTTP API (#443). +//! +//! When the `RUVIEW_API_TOKEN` environment variable is set, every request +//! whose path begins with `/api/v1/` must carry a matching +//! `Authorization: Bearer ` header, otherwise the server responds with +//! `401 Unauthorized`. When the env var is unset (or empty), the middleware is +//! a no-op and the API stays unauthenticated — preserving the long-standing +//! LAN-only deployment posture documented in the issue. This is a binary, +//! deployment-time switch with **no default authentication change**. +//! +//! Endpoints outside `/api/v1/*` (`/health*`, `/ws/sensing`, the static `/ui/*` +//! mount, `/`) are intentionally **not** gated: +//! * `/health*` is the liveness/readiness probe that orchestrators hit +//! anonymously; +//! * `/ws/sensing` and `/ui/*` are served to local browsers that can't easily +//! inject headers — the sensitive control plane is the `/api/v1/*` tree, and +//! that is what this layer protects. +//! +//! The header check uses a length-then-byte constant-time compare to avoid +//! leaking the token through timing. +//! +//! # Cognitum OAuth (ADR-271) +//! +//! A second, **additive** credential is supported: a Cognitum OAuth access +//! token, verified offline against `auth.cognitum.one`'s published JWKS.

Otherwise, if OAuth is configured, the bearer is verified as a JWT and +//! must carry the scope the route requires. +//! 3. Otherwise `401`. +//! +//! Order matters for compatibility, not for security: a static token that +//! matches is not a JWT, and a JWT never matches the static token. Trying the +//! static compare first means an existing deployment's behaviour is unchanged +//! even with OAuth switched on. +//! +//! **Nothing here weakens the unset case.** With neither variable set the +//! middleware is the same no-op it has always been. +//! +//! ## Scope gating +//! +//!

Live trust-path bridge: drive the governed [`StreamingEngine`] from the +//! sensing-server's live `NodeState` map. +//! +//! `multistatic_bridge.rs` already converts `NodeState` → `MultiBandCsiFrame` +//! and runs the *bare* `MultistaticFuser`.

Field-peak localization for the Observatory 3D view (issue #1050). +//! +//! ## What this is (and is not) +//! +//! The `/ws/sensing` `sensing_update` frame already carries a real `signal_field` +//! — a 20×20 grid built by `generate_signal_field()` from **measured subcarrier +//! variances** weighted by the **measured motion-band power**. The grid's hot +//! cells are the strongest scatterers in that field representation; as the CSI +//! changes (a person moving through the link), the peak cell moves with it. +//! +//! This module reads the **strongest peak(s)** out of that real field and maps +//! the peak cell to the Observatory room's world coordinates. That gives the +//! 3D figure a position + motion magnitude that are **derived from real signal +//! data**, so the figure now tracks where the field energy concentrates. +//! +//! ### Honesty caveat (do not over-claim) +//! +//! The field's subcarrier→angle mapping in `generate_signal_field()` is a +//! *representation*, not calibrated multistatic triangulation in metric room +//! coordinates. A single ESP32 link cannot resolve a true (x, z) room position. +//! So the emitted `position` is **"strongest field peak in the room model"**, +//! not survey-grade localization. It is real (a function of live CSI), it moves +//! with real motion, and it is honest about its source — but it is NOT a +//! calibrated person fix. Per-person skeletal `pose` keypoints in room +//! coordinates remain gated on the pose model + paired ground-truth data +//! (ADR-079), so `pose` here is only ever set from a real aggregate posture +//! estimate when one exists, and is `None` otherwise (never fabricated). +//! +//! ## Coordinate mapping +//! +//!

Only the **upper 4 bits** of the 12-bit discriminator survive in the +//! manual code (the "short discriminator", bits 8..11); the low 8 bits +//! are carried only in the QR payload, by design (§5.1.3.1). Chunk +//! maxima: chunk1 ≤ `(0x300<<6)|0x3FFF` = 65535 < 10^5, chunk2 ≤ 0x1FFF +//! = 8191 < 10^4, so each chunk is `format!`-padded to its width without +//! loss.

Masked-autoencoder (MAE) pretraining recipe for the ADR-150 RF foundation +//! encoder — ADR-152 §2.3 (amends ADR-150 §2.3). +//! +//!

This module provides the GPU-free half of the recipe: configuration, +//! patchification, and deterministic random masking.

A CSI window is `time × subcarriers`, row-major (`index = t * subc + sc`), +//! matching the crate's `[T, …, n_sc]` dataset layout (time first, subcarriers +//! last) and the UNSW "(30 time steps, 3 subcarriers)" patch framing. Patches +//! are indexed row-major over the patch grid (`p = pt * n_patches_subc + ps`), +//! and values within a patch are row-major time-major +//!

Falsifiable occupancy / presence benchmark over labeled CSI sequences. +//! +//! The beyond-SOTA system review found that "beyond SOTA" was *unfalsifiable*: +//! no real-CSI ground-truth benchmark existed, and the eval pyramid (doc 03) +//! lists the field's recurring measurement frauds — subject leakage between +//! train/test, per-environment overfitting, and **mock-mode contamination** +//! (CLAUDE.md: mock missed a real Kconfig bug). +//! +//! This module makes the claim falsifiable. It **grades** predictions against +//! ground truth (it does not run a model — keeping the eval crate light and the +//! scoring model-agnostic), and it enforces, *structurally*, the discipline +//! that prevents overclaiming: +//! +//! 1. **No SOTA claim on non-measured data.** A dataset is tagged +//! [`DataProvenance`]; only [`DataProvenance::Measured`] can release a claim. +//! Synthetic/Mock data can still be scored (useful for CI/regression) but the +//! [`ClaimGate`] returns [`NO_CLAIM`] — you cannot accidentally publish a +//! "beyond SOTA" number computed on simulated CSI. +//! 2. **No leaky splits.** [`EvalSplit::validate`] refuses a split where any +//! subject *or* environment id appears in both train and test. +//! 3. **Pre-registered thresholds + bootstrap CI.** The gate compares the +//! *lower* bound of a deterministic 95% bootstrap CI, not the point estimate, +//! so a lucky small-sample result cannot pass. +//! 4. **No degenerate test sets.** The test set must contain *both* truth +//! classes (present-rate ≥ `min_positive_rate`, and at least one absent +//! sample), with its own failure flag — an all-absent set plus an +//! always-absent predictor must never release a claim. Vacuous F1 (no +//! positives anywhere in the confusion) scores **0.0**, never 1.0. +//! +//! The harness is the same shape as the `ruview-gamma` acceptance gate: a single +//! `claim_allowed` invariant, and the claim string is unreadable except through +//! the gate. + +use std::collections::BTreeSet; + +/// Provenance of the labeled data a benchmark runs on.

External +attack/defense results cited from the literature (BFId, LeakyBeam, DySPAN-2026, +IRShield, FCC statutes) are **EXTERNAL** evidence and labelled MEASURED/CLAIMED in +the research bundle. The single measured claim about *our own behavior* is the +pinned deterministic witness in `proof.rs`. + +## 1. Context + +### 1.1 The gap + +IEEE 802.11ac/ax beamforming feedback (BFI) — the compressed Givens-rotation +angle matrices (φ/ψ) a client sends the AP — is transmitted **unencrypted on the +management plane**. Any device in monitor mode can capture it for every station +at once, no network access, and the target need carry no device. The literature +establishes the severity: **BFId** (ACM CCS 2025) re-identifies individuals from +BFI; **LeakyBeam** (NDSS 2025) detects occupancy through walls at 20 m from BFI; +**BeamSense** recognizes activities at up to 99.28%. IEEE Std **802.11bf-2025** +(published 26 Sep 2025) standardizes the sensing measurement/feedback surface +these attacks abuse — and a 2023 proposal for a BFI secure-transmission mechanism +(802.11-23/0782) was **withdrawn**, so the standard shipped with no privacy +protections. + +RuView already has a *detection* layer for this: **BFLD** (ADR-118/121) measures +the identity-leakage of each frame and gates what leaves the node. But BFLD +protects *RuView's own outputs*; it does nothing about a **third-party sniffer** +capturing the room's plaintext BFI off the air. There is no RuView component, and +per our market survey no shipping product anywhere, that prevents that. + +### 1.2 Constraint: compliant waveform controls, never jamming + +The defense must preserve normal communications and must not interfere with any +other station. Jamming (47 U.S.C. §333/§302a) is defined by *adding energy to +interfere with others' transmissions*. Any acceptable control must shape only the +node's **own** standards-conformant emission. + +### 1.3 The separability insight + +Identity leaks through the *fine* cross-subcarrier phase structure of a +beamforming report; data throughput rides the *dominant* beam direction. These +are (mostly) separable subspaces — so a transform confined to the fine subspace +can wreck re-identification while sparing the beam the link depends on. DySPAN-2026 +independently MEASURED that shaping fine-resolution feedback is near-free in +throughput, corroborating the insight. + +## 2. Decision + +Ship **`wifi-densepose-privshield`** (VEIL) as a standalone pure-compute leaf +crate (the `wifi-densepose-aether`/`nvsim` pattern: dependency-free, deterministic, +WASM-ready, zero coupling to any radio or ingestion path), implementing: + +1. **A SYNTHETIC two-subspace BFI model** (`identity.rs`): each identity owns a + stable fine-block signature; sessions add environmental nuisance; the comm + block is identity-free and carries throughput. +2. **The protector** (`protector.rs`): compliant waveform controls, primarily a + **per-session keyed orthogonal rotation of the fine subspace, composed from + extra Givens rotations** — the report's native primitive. Plus feedback + quantization/dither, sounding-cadence randomization, and a `SensingDetector` + that engages the shield only when sensing activity is observed. +3. **The adversary** (`attacker.rs`): a passive nearest-centroid re-identifier + modeling the BFId threat, with selectable Euclidean/Cosine metrics. +4. **A throughput model** (`throughput.rs`): + `(1 − sounding − feedback_airtime) · C(SNR·(1−ρ))/C(SNR)`, where the residual + `ρ` falls with feedback bits and the feedback airtime rises with them — giving + a genuine interior throughput optimum in feedback resolution. +5. **A compliance audit** (`compliance.rs`): the rotation is orthogonal ⇒ + energy-preserving ⇒ adds no interfering energy ⇒ **not jamming**, turned into a + checked `ComplianceReport` (energy ratio ≈ 1.0). +6. **The experiment** (`experiment.rs`): runs the attacker against unprotected and + protected traffic and reports both accuracies vs. chance, plus throughput and + compliance, with a single `passed()` verdict. +7. **The hyper-optimizer** (`optimize.rs`): derives the shipped shield config + rather than hand-picking it — the throughput-optimal feedback resolution and + the minimum rotation-mixing budget that collapses re-ID robustly (across both + attacker metrics and N∈{16,32}), plus a Pareto frontier. +8. **A deterministic proof** (`proof.rs`): a pinned FNV-1a witness over the + reference experiment (the `nvsim`/`verify.py` discipline). + +### 2.1 Why the keyed Givens rotation + +It is simultaneously **orthogonal** (energy-preserving ⇒ compliant), +**key-reversible** (the associated AP shares the session key and recovers the true +precoder ⇒ throughput preserved), and **fresh per session** (a sniffer sees a new +random rotation of the signature each session and cannot average it back ⇒ the +enrollment attack collapses; over unknown rotations the signature carries no +stable discriminative information ⇒ re-ID → chance). It is the shared-secret +precoding idea (cf. MIMOCrypt) specialized to the identity-bearing subspace. + +### 2.2 Measured behavior (SYNTHETIC / L0) + +Reference experiment at the hyper-optimized operating point (§opt), default +scene, N=16 identities, `cargo test`: + +| Metric | Shield off | Shield on | +|---|---|---| +| Passive re-ID accuracy | 100.0% | **4.7%** (chance 6.25%) | +| Link throughput ratio | 100% | **97.6%** | +| Emission energy ratio | — | **1.000000** (compliant) | + +All 35 unit/proof tests + doctest pass; the crate builds for +`wasm32-unknown-unknown` and is clippy-clean. + +### opt. Hyper-optimization (`optimize.rs`) + +The shipped shield config is the optimizer's output, not a guess, and +`ShieldConfig::default()` is asserted equal to it: + +- **Feedback resolution = 5 bits.** Throughput has an interior optimum in + feedback bits (residual falls, feedback airtime rises); the unconstrained + optimum is 3 bits (matching DySPAN-2026), and 5 is the throughput-best value in + the spec-allowed 802.11 {5,7,9} set. +- **Givens passes = 96.** The proven minimum for robust collapse — across both + attacker metrics *and* N∈{16,32} — is **48**; the shipped 96 is a free 2× + privacy margin, since the keyed rotation is derived from the shared secret and + never signaled (extra passes cost compute, not airtime). The original + hand-picked 112 was 2.3× over-provisioned. + +Net vs. the original hand-picked (112 passes / 7 bits): the optimum is strictly +better on **both** privacy (re-ID 0.047 vs 0.078) and throughput (0.976 vs 0.974), +and is now verified rather than assumed. See +`docs/research/privacy-shield/08-optimization.md`. + +### harness. Native terminal harness + TUI (`src/bin/veil.rs`) + +A custom, dependency-free binary (`veil`) ships with the crate — the in-repo, +native counterpart to the npm metaharness (ADR-289). It drives the same public +API the tests use, as an interactive ANSI dashboard plus scriptable subcommands +(`report`, `sweep`, `optimize`, `adaptive `, `proof`, `doctor`, `tui`). +Std-only (no `crossterm`/`ratatui`): the TUI is a command-driven redraw loop, so +it runs in any terminal, pipe, or CI and keeps the crate a pure leaf. It reports +only SYNTHETIC/L0 numbers and never relabels them. The wasm leaf story is +unchanged (validated with `--lib`; the bin is native-only). + +### sota. 2025–2026 evidence update (verified) + +A cited, adversarially-verified SOTA sweep +(`docs/research/privacy-shield/09-sota-update-2026.md`) refines the threat and +positioning. Load-bearing points for this ADR: + +- **Threat is broader and cheaper than §1.1 stated.** A passive, keyless, + single-antenna sniffer at ~20 m and *through walls* can identify people + (BFId, 99.5%/N=197, `MEASURED`), read **breathing** from stationary occupants + and **keystrokes/PINs** (LeakyBeam / WiKI-Eve / SThief, `MEASURED`), and — + decisively — **reconstruct full CSI from the sniffed BFI** (BFIAttack, + ≥93% single-antenna, `MEASURED`). VEIL's obfuscation must therefore degrade + *reconstructed-CSI* utility, not merely raw-BFI feature noise; because VEIL's + rotation is a **secret orthogonal** transform, the attacker has no key and no + closed-form to invert — this is now a claim to **test**, not assume. +- **VEIL's family is independently validated.** AP-side per-packet random + unitary on the LTF (LeakyBeam defense, 89.7%→~51%, `MEASURED`) and RIS + obfuscation (PrivISAC, 93%→~30%, robust to a retrained multi-location + attacker, `MEASURED`) confirm standard-permitted beamforming-surface + obfuscation works; DP-Givens quantization (`SYNTHETIC`) offers a formal ε knob. +- **Compliance precedent.** BeamDancer (IEEE TWC 2024, `MEASURED`) argues + native-beamforming obfuscation is 802.11-compliant while jamming/geofencing + are not — cite it as precedent. (Its ">96% PDR" figure was **refuted** in + verification; do not cite it.) +- **Security honesty.** Obfuscation shields have published counter-attacks + ("Defeating CSI obfuscation", SnoopFi), so VEIL's own shield security is + `CLAIMED`, not proven-secure, until it withstands learned de-obfuscation. +- **Governance gap.** No claim on 802.11bf-2025 privacy provisions survived + verification; that pillar remains an open question, not an asserted fact. + +The derived, prioritized improvement backlog lives in the SOTA-update file (§4). + +## 3. What this explicitly is NOT + +- **Not a radio driver.** No RF frontend, no transmit path, no + `wifi-densepose-hardware` coupling. VEIL cannot emit and cannot jam. +- **Not a defense against the associated AP.** That party holds the session key by + construction (threat class A3); protecting against a malicious AP is BFLD's + detection/privacy-class problem (ADR-118/141), not this shield's. +- **Not a full motion-obfuscation claim.** A fixed per-session rotation does not + hide coarse within-session motion; identity *re-ID* is the guaranteed target, + motion is partial/future work. +- **Not a real-hardware performance claim.** All defense numbers are SYNTHETIC/L0 + until a two-node capture with a boot/runtime-log witness exists (CLAUDE.md + hardware rule; roadmap P5). +- **Not RF denial or camera-grade anything.** + +## 4. Simplifications (honesty boundary) + +- The two-subspace split is an abstraction; on real radios comm and identity + information are only *approximately* separable, so the real throughput cost of + fully hiding identity may exceed the model's ~2%. DySPAN-2026's MEASURED curve + bounds it as *small* at fine resolution, not zero. +- The attacker is nearest-centroid. The collapse argument is classifier-independent + (it is about the marginalized signal), but P2/P5 must confirm a learned attacker + also collapses. +- The crate's PRNG is SplitMix64 — deterministic and WASM-safe but **not + cryptographic**; a deployment derives the rotation key from the negotiated link + secret, never from this PRNG. + +## 5. Consequences + +- RuView gains the *countermeasure* half of its RF-privacy story: BFLD detects + leakage, VEIL acts on it — a defensible, standards-anchored, gap-filling + position (see `docs/research/privacy-shield/06-market-and-buyers.md`). +- The compliance audit gives regulators/auditors a machine-checkable "not jamming" + artifact that composes with ADR-141 attestation. +- Future integration (BFLD `identity_risk` → `SensingDetector`, ADR-280 governed + actuation, firmware feedback shaping, two-node hardware measurement) is staged in + the research bundle roadmap and deliberately deferred so the model validates in + isolation first. + +## 6.

Decision + +Land the harness at `harness/wifi-densepose-privshield/`, mirroring +`wifi-densepose-sar-harness`, with two deliberate improvements: + +1. **Dynamic dependency imports.** `bin/cli.js` imports the `@metaharness/*` + packages *inside* the commands that need them, not at module top. So + `guidance`, `--help`, and the guidance test run with **zero dependencies + installed** — useful for offline/air-gapped review and for this repo's CI + before `npm install`. Only `init`/`doctor`/`route`/`flywheel` touch the + kernel/host/router/flywheel packages. +2. **A VEIL `guidance` command.** A self-contained, source-cited, read-only + capability map (topics: `overview`, `threat`, `countermeasure`, + `compliance`, `optimization`, `experiment`), each entry carrying a summary, + repo-relative source citations, focused validation commands, and explicit + limitations — the `ruview_guidance` shape, specialized to VEIL.

Labelled + examples are illustrative seed data (honesty note in-file). +- **`@metaharness/flywheel`** — `src/flywheel.ts` wires the real + `runFlywheelGenerations` promotion loop (propose → evaluate → gate → promote, + Ed25519-signed, independently replayable) with a SYNTHETIC proposer/evaluator + (`dataSource: 'SYNTHETIC'`, no model call), over VEIL policy levers + (`complianceReview`, `threatTriage`). + +## 3. What this explicitly is NOT + +- **Not a VEIL runtime.** The harness does not run a radio, emit RF, or jam. It + assists *development* on the crate; it cannot execute the shield on hardware. +- **Not evolving the crate.** Darwin/Flywheel mutate the harness's own policy + (agent prompts, review-checklist depth), not VEIL's Rust code. The crate's + actual hyper-optimization (ADR-288 §opt) was done directly, in the crate. +- **Not a live routing/promotion system.** The router's examples are seed data; + the flywheel's proposer/evaluator are deterministic stand-ins — both honestly + labelled in-source and in `CLAUDE.md`. +- **Not a replacement for the crate's gates.** The authoritative check for a + VEIL change remains `cargo test -p wifi-densepose-privshield`. +- **Not a re-labeller.** The harness must never present VEIL's SYNTHETIC results + as MEASURED, and never scaffold interference-based ("jamming") defenses — both + are hard rules in the harness `CLAUDE.md`. + +## 4.

Carries the **P5 measurement protocol** + (`MEASUREMENT.md`) that yields the first `MEASURED` result with a witness. + - **`openwrt/`** (Linux `mac80211`, mt76/ath9k…) — the commodity path. + Sounding-cadence randomization, MU-group and stream-mapping control are + feasible from the driver/hostapd; the per-packet unitary on the LTF spatial + mapping is firmware-deep on most parts. Partial. + - **`nexmon/`** (Broadcom/Cypress C firmware patches) — the commodity + C-firmware route; the read path is proven (Wi-BFI/nexmon_csi), the transmit + report-shaping path is research-grade/partial. + - **`esp32/`** (ESP-IDF) — **not** a feedback protector (the beamforming path + is a closed blob): ESP32 shapes CSI *read*, not transmitted feedback. Its + legitimate roles are a **sensing detector** (trigger the AP-side shield) and + an **RIS controller** (drive an external reconfigurable surface to scramble + the sensing direction — the honest way ESP32 "helps scramble", via an + external surface, not its own PHY). +3. **Compliance stance carried into hardware:** every control shapes the node's + own standards-conformant emission and preserves energy; the ESP32 + decoy/cover-traffic idea is documented as *legally sensitive / not + recommended* precisely because it edges toward the interference line. + +Per-provider feasibility grades live in each subdir README and the top-level +feasibility matrix; they are the answer to the "which hardware" question. + +## 3.

Why the keyed Givens rotation is the right primitive + +The compressed beamforming report is *already* a product of Givens rotations +(the φ/ψ angles). VEIL composes **additional keyed Givens rotations** over the +fine block. This choice gives three properties at once: + +1. **Orthogonal ⇒ energy-preserving.** A Givens rotation preserves the vector's + L2 norm exactly. Composing many still preserves it. So the emission carries + the same power it always would — **no added energy, no interference, not + jamming.** The `compliance` module checks this: energy ratio = 1.000000. +2. **Keyed & reversible ⇒ throughput-preserving.** The legitimate AP/STA shares + the per-session key, derives the identical rotation schedule, and applies the + inverse (negated angles, reversed order) to recover the true precoder. It pays + only the tiny residual from quantizing the extra angles at `feedback_bits` + resolution — negligible across the 802.11 5–9-bit range — plus the sounding + overhead. (The throughput-optimal resolution is derived in + [08-optimization.md](08-optimization.md).) +3. **Fresh per session ⇒ unlinkable.** A different rotation each session means an + A1 sniffer sees `R_e · signature` for a new random `R_e` every time. Averaging + over sessions (the natural enrollment attack) drives + `mean_e(R_e · signature) → 0` for *every* identity, so all templates collapse + toward the origin and become indistinguishable — re-identification → chance. + This is the marginalized-mutual-information argument: over unknown rotations, + the signature carries no stable discriminative information. + +This is the shared-secret precoding idea (cf.

On the ESP32 that report is generated **inside the closed Espressif +Wi-Fi PHY/MAC binary blob** (`esp-phy-lib`, shipped in object form; the Wi-Fi +stack is a proprietary blob bound by a hardware NDA and third-party IP +licensing). There is **no ESP-IDF API to intercept, replace, or rotate the +compressed-BF-report the PHY emits.** `esp_wifi_80211_tx()` lets you inject raw +frames, but it is explicitly limited to *beacon, probe req/resp, (non-QoS) data, +and action* frames with the PHY choosing the actual precoding — it will not let +you hand-craft the VHT/HE sounding-feedback subtype with a chosen precoder. So +the ESP32 is **not** a beamforming-feedback protector. + +**Feasibility grade for "ESP32 as a self-protecting WiFi Veil node": F (infeasible).** +The one waveform we need to touch is behind a blob with no hook. + +**Feasibility grade for "ESP32 as a WiFi Veil supporting device": B (feasible, +build-only).** Three legitimate roles below, best-first. + +--- + +## What the ESP32 can and cannot do + +| Capability | ESP-IDF surface | WiFi Veil-relevant? | Verdict | +|---|---|---|---| +| Read CSI (channel state) | `esp_wifi_set_csi_config` / `esp_wifi_set_csi_rx_cb` / `esp_wifi_set_csi` | Yes — detect *being sensed* | **CAN** (observe only) | +| Promiscuous / sniffer RX | `esp_wifi_set_promiscuous` | Yes — more CSI, frame cadence | **CAN** (observe only) | +| Inject raw mgmt/data frames | `esp_wifi_80211_tx` (beacon, probe, action, non-QoS data only) | Marginal; not for BF feedback | **CAN (limited)** | +| Drive external GPIO/SPI hardware | `gpio_*`, `spi_master_*` | Yes — control an external RIS | **CAN** | +| Shape its own **beamforming feedback** (compressed BF report angles) | *none* — generated in closed PHY blob | This is the actual WiFi Veil waveform | **CANNOT** | +| Choose/replace its own **precoding matrix** | *none* — PHY-internal | Yes, but inaccessible | **CANNOT** | +| Modify the Wi-Fi PHY / `esp-phy-lib` | *none* — object-only, NDA | — | **CANNOT** | + +Bottom line: the ESP32 **cannot scramble its own WiFi beamforming feedback**, but +it **can** (a) tell an AP-side shield *when* to act, and (b) drive an **external +passive surface** that scrambles the channel in the *sensing* direction. The +latter is the only honest sense in which an ESP32 "helps scramble" a signal, and +it does so without the ESP32 emitting any RF of its own. + +--- + +## The three legitimate roles + +### 1. `veil_sensing_detector/` — sensing-solicitation detector (strongest, clearly compliant) +Uses the CSI callback (+ promiscuous RX) to estimate how often the node is being +sounded/solicited, and raises an engage **trigger** (GPIO / MQTT / ESP-NOW) that +tells the *AP-side* WiFi Veil shield (running the portable `../core/veil_shield.c`) to +turn on. Pure observe-plus-control-signal; the ESP32 shapes nothing on air. This +is the role we would actually build first. + +### 2. `veil_ris_controller/` — external RIS driver (the honest "help scramble") +Drives a **reconfigurable intelligent surface** over GPIO/SPI. Following the +PrivISAC pattern, each surface element has two phase states designed offline so +the array response is ~identical in the *communication* direction (throughput +preserved) but differs sharply in the *sensing* direction (an eavesdropper's +channel is perturbed). The ESP32 is just a keyed pin-driver; the surface is +**passive** (re-reflects ambient energy, adds none), which is what keeps this on +the compliant side of the jamming line. The switching **schedule is keyed** via +the portable core's `veil_rng` (SplitMix64), so an authorized sensor holding the +key can reconstruct and tolerate the schedule while an eavesdropper cannot. + +### 3. `esp_wifi_80211_tx` action-frame signaling (minor) +Not a separate component. The trigger in role 1 could ride an action frame via +`esp_wifi_80211_tx` instead of GPIO/MQTT/ESP-NOW. Useful only as a transport for +the control signal — it does **not** touch beamforming feedback. + +--- + +## Not recommended: decoy / cover-traffic + +One could have the ESP32 emit extra frames (via `esp_wifi_80211_tx`) to inject +motion-like or clutter-like variation into an observer's CSI ("cover traffic"). +**We do not implement this and do not recommend it.** It is (a) **legally +sensitive** — deliberately adding channel-occupying transmissions to degrade +another party's reception sits close to the *jamming* line and can violate +radio regulations depending on rate, power, and intent; and (b) **low-value** — +it costs airtime, harms your own network, and a determined observer can often +filter periodic decoys. It is documented here only so the option is explicitly +weighed and rejected in favor of the passive-RIS approach (role 2), which +perturbs the *sensing* direction without occupying spectrum. + +--- + +## Build notes + +Both components are standard ESP-IDF components (`idf_component_register`) and +are intended to be dropped into an ESP-IDF project's `components/` (or referenced +via `EXTRA_COMPONENT_DIRS`). `veil_ris_controller` compiles the portable core +(`../core/veil_shield.c`) directly to reuse `veil_rng`.

Published reverse-engineering of these chips reports that the D11 +generates the **VHT/HE compressed beamforming report ~10 µs after the NDP**, with +its contents fetched from an **internal memory updated directly by the hardware** +on NDP reception. In other words, the angles WiFi Veil wants to touch are staged and +emitted inside the ucode/PHY path on a microsecond deadline — *below* the ARM +"wl" driver firmware where Nexmon's C hooks (`__attribute__((at(addr, ...)))` +flashpatches / branch hooks) live most reliably. Reaching them means either a +D11-ucode patch (needs the D11 assembler and SHM/template-RAM layout) or catching +the report while the ARM path still assembles the action-frame body — if it does +so on this chip at all. Both are `TODO(reverse-engineer)`. + +## Target chip(s) + +Primary: **BCM43455c0** (Raspberry Pi 3B+/4B; also RPi Zero 2 W), firmware +**7_45_154** (Raspbian) or **7_45_189** (Cypress) — the best-documented, +most-reproducible Nexmon target, and one of the four chips `nexmon_csi` already +supports. Secondary candidates that `nexmon_csi` also supports: **BCM4339** +(Nexus 5), **BCM4358** (Nexus 6P), **BCM4366c0** (Asus RT-AC86U). We scope the +skeleton to BCM43455c0 / 7_45_189 and leave the others as build-matrix `TODO`s. + +Caveat: the RPi BCM43455c0 is an **802.11ac (VHT)** single-stream part; its own +*transmit* beamforming/sounding activity as a beamformee is limited. The +skeleton targets the **VHT compressed beamforming report** action-frame path; +whether this chip emits enough to shape in practice is itself a `TODO(hw)` +question. + +## Hook-point candidates (all `TODO(reverse-engineer)`) + +Ordered most-tractable → deepest. Addresses are **placeholders** — real offsets +come from disassembling the specific firmware blob and cross-checking the Nexmon +symbol tables (`wl_ram.elf` / IDA); none are known-good here. + +1. **ARM action-frame TX assembly (best first target).** If the "wl" driver + assembles the VHT Compressed Beamforming Report action-frame *body* in ARM + firmware before handing it to the D11 (function family around + `wlc_txbf_*` / a `wlc_send*mgmt`/action path), a branch hook there could + locate the report's fine-angle block and call `veil_shield_apply` in place. + Cheapest if it exists on this chip. +2. **ARM → D11 TX descriptor / template handoff.** Hook where the driver stages + a frame into the D11 TX FIFO / template RAM (`wlc_d11hdrs` / `wlc_txfifo` + region) and rewrite the angle bytes there. Requires knowing the exact + template-RAM offset of the report body. +3. **D11 ucode patch (deepest).** Patch the ucode routine that copies angles + from the hardware-updated internal memory into the outgoing report, applying + the rotation in D11 SHM.

Reaching a true two-stream demo needs a **second TX chain** (the AD9361 on + fmcomms2/3 has two DACs) plus a new spatial-mapping RTL stage and a Vivado + rebuild — days-to-weeks of FPGA work, not a driver patch. + +Because of (1), on openwifi WiFi Veil is realized as the **client-transparent +per-packet keyed unitary** (LeakyBeam family) applied at the TX spatial-mapping +stage, with the legitimate STA (a second openwifi node sharing the key) +inverting it — **not** as obfuscation of a compressed-BF report the hardware +never produces. This keeps the claim honest: we rotate the *transmitted spatial +mapping* so a sniffer's per-subcarrier channel estimate `H·Q(key)` is scrambled, +and the keyed receiver applies `Q(key)^H` before channel estimation. + +## Exact insertion points + +The rotation is a keyed orthogonal (unitary) matrix `Q(key, session)` computed +by the portable core (`../core/veil_shield.{h,c}`), the same SplitMix64 schedule +used everywhere, so both ends derive the identical `Q` from the shared key. + +**TX (protector) — FPGA, new block `veil_rot`:** +Insert on the baseband IQ AXI-Stream path **between `openofdm_tx` (post-IFFT, +post-CP) and `tx_intf`** (which feeds the AD9361 DAC). `veil_rot` left-multiplies +the per-subcarrier / per-stream sample vector by `Q(key)`.

    How this protects you

    plain language
    +
    +
    + + The threat +

    Your Wi-Fi constantly sends the router fine signal details — in the clear. A stranger nearby can capture them and recognise individual people by their radio "fingerprint": through walls, with no camera, and nothing on you.

    +
    +
    + + The shield +

    WiFi Veil scrambles that fingerprint on every report with a secret twist only your own router can undo. An outside listener sees a different scramble each time and can't tie it to a person — their guess of "who's here" drops to pure chance.

    +
    +
    + + Kept honest +

    It shapes only your own signal — it never jams, and your Wi-Fi speed stays ~98%. It stops outside snoops, not the router you connect to. Figures here are simulated (L0), pending real-hardware tests.
