chore: update vendor submodules to latest upstream

fix release publishing pipelines (#1417 )
Make deployment consume the exact published sensing-server image, publish the two Python packages in lock-step, and enforce the production witness gate.

+# Sub-deliverable 8.3 of the benchmark/optimization milestone.
+#
+# HONEST SCOPE (read this before assuming this gates on timing):
+#   * The `bench-compile` job is a REAL, HARD-FAILING regression gate. It runs
+#     `cargo bench --no-default-features --no-run`, which type-checks and links
+#     EVERY criterion bench in the v2/ workspace without running a single
+#     measurement. Benches are not part of `cargo test`, so they silently
+#     bit-rot when a public API they call changes — this job catches that the
+#     moment it happens. This is the part of this workflow that can fail a PR.
+#
+#   * The `bench-fast-run` job runs a small, curated subset of pure-CPU benches
+#     in criterion "quick mode" (short warm-up / measurement / 10 samples) and
+#     is INFORMATIONAL ONLY (`continue-on-error: true`). It does NOT gate on
+#     timing. Wall-clock timings on shared GitHub-hosted runners vary by
+#     2-3x run-to-run (noisy neighbours, CPU throttling, no pinned frequency),
+#     so a hard ">X ms" threshold here would flake constantly and teach
+#     everyone to ignore it. We deliberately do not pretend to do timing
+#     regression-gating we cannot deliver reliably. The numbers are surfaced in
+#     the job log + uploaded as an artifact for humans to eyeball trends.
+#
+# WHY NO criterion --baseline COMPARE GATE:
+#   criterion's `--save-baseline` / `--baseline` compare is the textbook
+#   regression mechanism, but it only produces a trustworthy verdict when the
+#   baseline and the candidate were measured on the SAME hardware under the SAME
+#   conditions. GitHub-hosted runners give neither (the baseline commit and the
+#   PR commit land on different physical machines). Committing a baseline JSON
+#   measured on one runner and comparing a different runner against it would
+#   manufacture false regressions. If/when these benches run on a dedicated,
+#   frequency-pinned self-hosted runner, a `--baseline` compare with a generous
+#   (>2x) noise floor becomes honest and can be added then. Until then,
+#   compile-verify + informational-run is the honest gate.

+# `archive/v1/` Python app — which is `continue-on-error: true` in ci.yml
+# because it is reference-only — the `python/` package is an actively-shipped
+# PyPI wheel (published by pip-release.yml). Before this workflow, `python/`
+# had ZERO per-PR coverage: pip-release.yml only fires on release triggers
+# (tags / dispatch), so a PR could break the wheel build, break a native-Rust
+# parity test, or blow the wheel-size budget and nothing in the normal gating
+# CI would notice until release day. This workflow closes that gap.
+#
+# Path-scoped as a DEDICATED workflow rather than a job inside ci.yml. That is
+# this repo's own convention for component-scoped CI (cf. firmware-ci.yml,
+# sensing-server-docker.yml, bfld-mqtt-integration.yml — all separate files
+# with `paths:` triggers). GitHub only supports workflow-level `paths:`, not
+# per-job path filters, and no workflow in this repo uses a change-detection
+# action (dorny/paths-filter, tj-actions/changed-files) — so the idiomatic,

+# PROOF — reproduce every claim, or find the one we can't yet
+
+This project (RuView / wifi-densepose) has been publicly called "AI slop" and
+"fake." This document is the answer: **a skeptic can clone the repo, run one
+script, and have every headline claim either verified on their own machine or
+shown — explicitly — as "CLAIMED, not yet reproduced (here's exactly what it
+needs)."** Nothing below is asserted without a command you can run.
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView
+bash scripts/prove.sh          # core gate + the anti-slop assertion tests
+bash scripts/prove.sh --full   # also attempt the feature-gated subset
+```
+
+`prove.sh` exits 0 only if every **non-gated** claim passes. Gated claims never
+fail the run; they print the prerequisite (a GPU, a dataset, real hardware, a
+trained checkpoint) so you can reproduce them yourself.
+
+## Grading
+
+- **MEASURED** — reproduced on our hardware, with the exact command recorded, and
+  pinned by a test that *fails on the pre-fix code*. `prove.sh` re-runs these.
+- **CLAIMED** — cited from a source, or measured by the source, but not
+  reproduced in this repo's automated harness.
+- **DATA-GATED / HARDWARE-GATED** — the *code path* is real and tested, but the
+  *accuracy/throughput claim* needs data or hardware we don't ship. We never
+  fabricate the number; the code carries a typed error or a `weights_trained`/
+  provenance flag instead.
+
+## The hard gate (run on any machine with Rust + Python)

+## What we do NOT claim (the honest negatives — the strongest anti-slop signal)
+
+| Capability | Status |
+|---|---|
+| **Named person-identity from WiFi** | **NOT achieved, and measured why.** The §3.6 matcher is real, but identity does not lock on WiFi-only channels (gap 0.0005). DATA-GATED on a real enrollment feeding the AETHER/body-resonance channel — never done. No named-identity claim is made. |
+| WiFlow-STD ~96% PCK@20 | **CLAIMED-reproduced** on our RTX 5080 (`benchmarks/wiflow-std/RESULTS.md`); HARDWARE-GATED for you (needs an NVIDIA GPU + the MM-Fi dataset). The upstream *shipped checkpoint* was **REFUTED** (0.08% PCK) — we publish that. |
+| OccWorld trajectory accuracy | DATA-GATED on a trained checkpoint; `predict()` carries `weights_trained=false` until one is loaded — never silently faked. |
+| Edge-skill detection accuracy (seizure, weapon, affect, …) | UNVALIDATED — every such module is now disclaimer-gated as experimental/research; the DSP is real, the accuracy is not claimed. |
+| 802.11bf-2025 OTA conformance | No commodity silicon ships a conformant interface as of 2026; ours is a simulation-tested forward-compat protocol model, not a certified implementation. |
+
+## Provenance
+
+Every claim above traces to a committed ADR (`docs/adr/ADR-154`…`ADR-163`), a
+test, a criterion bench, `benchmarks/wiflow-std/RESULTS.md`, or
+`benchmarks/edge-latency/RESULTS.md`. The history
+includes published **retractions** (the 92.9% PCK retraction; the WiFlow-STD
+shipped-checkpoint refutation; the NV-diamond BOM reality check) — a faker hides
+failures; we commit them.

+single-antenna, 56-subcarrier CSI stream at a 20-frame window does *not* carry the
+fine-grained spatial information the multi-antenna NIC research relies on — the cog
+measurements above show distal/face joints near-random. The shippable pose accuracy the
+project can stand behind today is the **MM-Fi benchmark number**, not a live single-ESP32
+number. The path to a first *reproducible* on-device baseline (PCK@20 ≥ 35%) is tracked in
+[ADR-079](docs/adr/ADR-079-camera-ground-truth-training.md) / [#645](https://github.com/ruvnet/RuView/issues/645) — do not advertise the live single-ESP32 17-keypoint feature without the "first-cut, below-target, runtime-stub" caveat until that baseline is measured.

+# ⚠️ DEPRECATED — `archive/v1` is unmaintained and superseded
+
+**Do not build new work on this tree.** `archive/v1` is the original pure-Python
+implementation of WiFi-DensePose. It is kept only as a research archive
+(per [ADR-117 §1.3](../../docs/adr/ADR-117-pip-wifi-densepose-modernization.md)) and
+as the host of one still-live deterministic proof (see "What still lives here" below).
+Everything else in this directory is frozen and receives no fixes, reviews, or support.
+
+Governed by [ADR-187](../../docs/adr/ADR-187-archive-v1-deprecation-honest-labeling.md).
+
+## The one honest fact that trips people up
+
+`archive/v1/src/models/densepose_head.py` defines a `DensePoseHead` neural-network
+architecture (segmentation + UV-regression heads). **It ships no trained weights.** Its
+`_initialize_weights()` uses `kaiming_normal_` **random initialization only** — there is
+no checkpoint-loading path in the class, and there are **zero** `.pth` / `.onnx` /
+`.safetensors` / `.pt` / `.ckpt` / `.bin` files anywhere under `archive/v1/`.
+
+So: the architecture is *defined*, but it is **architecture-only**. Running it produces
+random output, not real pose accuracy. This matches the technical review in
+[#509](https://github.com/ruvnet/RuView/issues/509) — for *this tree*, the "network
+defined, no pre-trained weights" observation is TRUE.
+
+Real, trained, benchmarked weights **do** exist — just not here. They live in the
+maintained `v2/` workspace and on Hugging Face (see next section).

+# Edge-Latency Benchmark Results — ADR-163
+
+Converting **CLAIMED** edge latency budgets into **MEASURED-on-host** numbers,
+closing the measurement debt flagged by Milestones 5/6 (ADR-159 / ADR-160).
+Benches + docs only — **no production-code behavior changed**.
+
+## The honest caveat, up front (read before citing any number)
+
+Two distinct gaps separate every number below from the figure it is converting:
+
+1. **Host ≠ ESP32.** The wasm-edge skill modules document budgets *"on ESP32-S3
+   WASM3"* (e.g. `exo_time_crystal`: "H (<10 ms)"). These benches run **native
+   x86_64 on a development laptop**, not the Xtensa/WASM3 target. A native host
+   median is an **upper bound on the algorithm's work**, not the ESP32 number.
+   WASM3 interpretation on a ~240 MHz Xtensa core is typically 1–2 orders of
+   magnitude slower than native `-O` host code, so a host median far under the
+   budget **does NOT prove the ESP32 meets it.** *The ESP32 figure is NOT
+   reproduced here — it needs hardware.*
+
+2. **Bench ≠ the doc-claimed measurement.** For the cogs, the manifest cites a
+   **cold-start** number (`cold_start_ms_avg`, weight-load included); these
+   benches measure **steady-state** per-frame `infer` (warm, weights resident).
+   Different measurements; we report both, labelled.
+
+Grades (per `benchmarks/wiflow-std/RESULTS.md` / ADR-152 vocabulary):
+- **MEASURED-on-host** — reproduced in this repo on the machine below, exact
+  command recorded. NOT the ESP32 / NOT the cold-start figure.
+- **CLAIMED (ESP32)** — the doc budget; UNMEASURED on hardware here.
+
+## Machine
+
+| | |
+|---|---|
+| Host | `ruvzen` (Windows 11, this dev box) |
+| CPU | Intel Core Ultra 9 285H |
+| Toolchain | `cargo 1.91.1`, `--release` (opt-level per crate profile) |
+| Bench harness | criterion 0.5 (`time: [low **median** high]` reported below) |
+| Date | 2026-06-12 |
+
+Run-to-run spread on this box is non-trivial (criterion's low/high bracket the
+median by a few %); the medians below are single-session captures with the smoke
+settings `--warm-up-time 1 --measurement-time 2` (wasm-edge) / `3` (cogs). Re-run
+for your own machine — the absolute numbers are host-specific.
+
+---
+
+## T1 — wasm-edge `process_frame` hot paths (ADR-160 deferred item → DONE host)
+
+The crate is **excluded from the v2 workspace**; bench from the crate dir.
+
+```bash
+cd v2/crates/wifi-densepose-wasm-edge
+cargo bench --features std -- --warm-up-time 1 --measurement-time 2
+# med_seizure_detect is medical-experimental-gated:
+cargo bench --features std,medical-experimental -- --warm-up-time 1 --measurement-time 2 med_seizure
+```
+
+| Hot path (M6-audit-named) | Bench id | Host median | Grade | Doc budget (CLAIMED, ESP32) |
+|---|---|---|---|---|
+| `exo_time_crystal` 256-pt × 128-lag autocorrelation (full buffer) | `exo_time_crystal::process_frame[autocorr_256x128]` | **17.3 µs** | MEASURED-on-host | "H (<10 ms) on ESP32-S3 WASM3" — **NOT reproduced here (needs hardware)** |
+| `exo_ghost_hunter` empty-room periodicity + hidden-breathing | `exo_ghost_hunter::process_frame[empty_room_periodicity]` | **1.44 µs** | MEASURED-on-host | research/exotic; no firm ESP32 figure — host proxy only |
+| `sec_weapon_detect` per-subcarrier Welford (MAX_SC=32) | `sec_weapon_detect::process_frame[per_sc_welford]` | **0.42 µs** (420 ns) | MEASURED-on-host | research-grade; calibration-gated — host proxy only |
+| `med_seizure_detect` clonic-phase rhythm path (steady-state frame) | `med_seizure_detect::process_frame[clonic_rhythm]` | **0.10 µs** (105 ns) | MEASURED-on-host (feature-gated) | doc budget "S (<5 ms) on ESP32"; **NOT reproduced here** |
+
+Reading these honestly:
+
+- `exo_time_crystal` at **17.3 µs host** is the only one whose host cost is even
+  in the same *thousandths* of its 10 ms ESP32 budget — it does the most work
+  (~32K MACs/frame). 17.3 µs native says the algorithm is cheap; it says
+  **nothing** about whether WASM3-on-Xtensa lands under 10 ms. A naïve
+  host→ESP32 extrapolation (assume 100× interpreter+clock penalty) would put it
+  near ~1.7 ms, comfortably under — **but that is an extrapolation, not a
+  measurement**, and is recorded here only to show the host number is not
+  obviously in tension with the budget. ESP32 figure: **UNMEASURED**.
+- `med_seizure_detect`'s 105 ns is the **steady-state** per-frame cost; the
+  expensive clonic autocorrelation only fires when the state machine is in the
+  clonic phase, so this is a lower-bound on the heavy path, not the worst case.
+  It is still a real, committed host datapoint.
+- The pre-existing `tests/budget_compliance.rs` already asserts the L/S/H
+  wall-clock tiers (25 passing tests); these criterion benches add the
+  regression-grade, reproducible median that ADR-160 deferred.
+
+---
+
+## T2 — cog steady-state inference latency (ADR-159/160 deferred item → DONE)
+
+Cog crates are normal workspace members; bench from `v2/`. Real weights
+(`count_v1.safetensors` / `pose_v1.safetensors`) ship in-repo under each cog's
+`cog/artifacts/`, so the bench measures the **real Candle CPU forward**, not the
+stub (the bench `assert!`s `backend().starts_with("candle-")`).
+
+```bash
+cd v2
+cargo bench -p cog-person-count  --no-default-features --bench infer_bench -- --warm-up-time 1 --measurement-time 3
+cargo bench -p cog-pose-estimation --no-default-features --bench infer_bench -- --warm-up-time 1 --measurement-time 3
+```
+
+| Cog | Bench id | Host median (steady-state infer, CPU) | Grade | Manifest cold-start (CLAIMED, different measurement + machine) |
+|---|---|---|---|---|
+| cog-person-count | `cog_person_count::infer[cpu_real_weights_steady_state]` | **305 µs** (idle box) | MEASURED-on-host | — (person-count manifest carries comparable provenance) |
+| cog-pose-estimation | `cog_pose_estimation::infer[cpu_real_weights_steady_state]` | **305 µs** (idle box) | MEASURED-on-host | `cold_start_ms_avg: 5.4` (30 invocations, **ruvultra/RTX 5080 host**, candle 0.9 cpu) — **cold-start, NOT steady-state; NOT this machine** |
+
+> Spread caveat (observed, honest): both medians above were captured with the box
+> otherwise idle. A re-run of the validate-form command *while a second cargo job
+> was loading the same cores* gave 385 µs (person-count) / 973 µs (pose) —
+> the criterion low/high bracket widens to ~0.34–1.18 ms under contention. The
+> 305 µs figures are the idle-box datapoints; the absolute number is host- and
+> load-dependent (the ~10× pose swing is core contention, not a code change).
+
+Reading these honestly:
+
+- **Steady-state ≠ cold-start.** The pose manifest's `5.4 ms` folds in one-time
+  weight load / mmap / first-forward allocation. This bench warms the engine
+  first and times only the recurring per-frame forward, on a *different
+  machine*. The two numbers are not comparable and we do not claim this bench
+  reproduces the 5.4 ms manifest figure.
+- Both cogs share the same conv encoder; person-count adds a count head +
+  confidence head, pose adds a 256-wide MLP head. The host steady-state cost is
+  dominated by the three dilated Conv1d layers (56→64→128→128) shared by both —
+  which is why both land at ~305 µs.
+- **Empirical confirmation of the steady-state/cold-start gap:** pose
+  steady-state (305 µs host) is ~18× *under* the manifest's 5.4 ms cold-start.
+  Even accounting for the different machine, this is the expected shape — the
+  bulk of cold-start is one-time setup, not the forward pass — and it is exactly
+  why conflating the two would be dishonest.
+
+---

+
+### Caveats on individual results
+
+† **exo_time_crystal — honest discriminative limit.** A *pure* periodic signal
+already has autocorrelation peaks at lag L **and** 2L (natural harmonics), so this
+"period-doubling" detector cannot separate a true period-2 sub-harmonic from a
+plain periodic signal — an earlier plant using a clean sine produced a *false
+positive* (recorded during development). The construct it **can** discriminate
+with known ground truth is **periodic-coordination vs aperiodic** (noise/flat),
+which is what is measured (1.000). The original "sub-harmonic vs clean period"
+claim is **NOT** validatable with this algorithm.
+
+‡ **spt_spiking_tracker — plant must be sparse.** With weights init'd home=1.0 /
+cross=0.25, firing all 8 inputs in a zone (8×0.25=2.0 > threshold 1.0) overdrives
+*every* output neuron and the tracker collapses to zone 0 (measured 1/4 during
+development). Firing only 2 inputs (home 2.0 fires, cross 0.5 silent) yields clean
+4/4 zone localization. The validatable claim is *single-zone* localization.
+
+§ **lrn_dtw_gesture_learn — enrollment validated; replay-match NOT.** The
+deterministic, constructible part (stillness → 3 identical rehearsals → a template
+is enrolled) is MEASURED. The DTW *replay match* (731) did **not** fire on the
+identical replay in this run (`match_same=false`) — replay-recognition accuracy is
+**reported, not asserted**, and is not claimed as validated.
+
+¶ **sig_sparse_recovery — trigger validated; recovery accuracy is NEGATIVE.**
+The dropout-detection + ISTA-recovery *trigger* pipeline fires correctly on >10%
+planted nulls (asserted). But the **measured recovery accuracy is NOT a win**:
+recovered RMSE **1.0045** vs unrecovered-null RMSE **0.9830** (**−2.2%**, i.e.
+slightly *worse* than leaving the nulls at zero) on a neighbor-correlated signal.
+The tridiagonal correlation model's fixed point does not equal the planted truth.
+**The recovery's reconstruction quality is therefore NOT validated as effective on
+synthetic data** — only its detection/trigger path is. Reported honestly; no
+positive number claimed.
+
+---
+
+## DATA-GATED — NOT validatable on synthetic data
+
+Planting a "seizure-like" / "weapon-like" / "happy-like" synthetic signal and
+claiming the detector "works" validates **nothing real** and is exactly the
+AI-slop this project fights. These skills run real DSP (per ADR-160, 0 stubs) and
+keep their ADR-160 disclaimers, but get **no accuracy number** here. Each needs
+the specific real, labelled data listed:
+
+| Skill | Why not constructible on synthetic | Real data required |
+|-------|------------------------------------|--------------------|

+| `med_sleep_apnea` | a planted breathing-pause is not clinical apnea (AHI scoring, hypopnea, desaturation) | Polysomnography-labelled (PSG) overnight CSI with scored apnea/hypopnea events |
+| `med_cardiac_arrhythmia` | a synthetic HR sequence cannot encode true arrhythmia morphology | ECG-labelled CSI (AFib/PVC/etc.) from clinical monitoring |
+| `med_respiratory_distress` | distress is a clinical gestalt, not a plantable rate | Clinician-labelled respiratory-distress CSI episodes |
+| `med_gait_analysis` | clinical gait metrics need a reference motion-capture standard | Mocap-/force-plate-labelled gait CSI |
+| `sec_weapon_detect` | a high variance ratio is RF reflectivity, **not** weapon discrimination (ADR-160 §A3 already renamed the event to `HIGH_METAL_REFLECTIVITY`) | Labelled metal-object-vs-no-object CSI with controlled object classes |
+| `exo_emotion_detect` | affect is not recoverable from a planted heuristic; outputs are proxies (ADR-160 §A2) | Validated affect-labelled CSI (self-report / physiological ground truth) |
+| `exo_happiness_score` | "happiness" is a gait-energy proxy, not a measured affect (ADR-160 §A2) | Validated affect/valence-labelled CSI |
+| `exo_dream_stage` | sleep staging needs PSG reference (EEG/EOG/EMG) | PSG-staged overnight CSI |

+## Implementation Notes
+
+### 2026-06 — ESP32 edge vitals: person-count over-count + presence flicker (#998, #996)
+
+Two robustness bugs were fixed in the on-device edge path (`firmware/esp32-csi-node/main/edge_processing.c`, the ADR-039 packet `0xC5110002`). These touch the *boolean/count emission logic*, not the underlying CSI signal-processing math, and do **not** constitute a validated-accuracy claim — true occupancy-count and presence accuracy vs labelled ground truth remain hardware/data-gated (COM9 ESP32-S3 + labelled capture).
+
+- **#998 `n_persons` over-count (reported 4 for one person).** `update_multi_person_vitals()` divided the top-K subcarriers into `top_k_count/2` groups and marked *every* group `active`, so one body's multipath always read the full `EDGE_MAX_PERSONS`. Added an energy gate (`EDGE_PERSON_MIN_ENERGY_RATIO`), spatial dedup (`EDGE_PERSON_MIN_SC_SEP`), and a persistence debounce (`EDGE_PERSON_PERSIST_FRAMES`) via two pure functions `count_distinct_persons()` / `person_count_debounce()`.
+- **#996 presence flag flicker at ~50 cm.** Single-threshold compare on a noisy `presence_score` chattered at the boundary. Replaced with a Schmitt trigger + clear-debounce (`presence_flag_update()`, constants `EDGE_PRESENCE_HYST_RATIO` / `EDGE_PRESENCE_CLEAR_FRAMES`); `presence_score` is unchanged and still emitted for consumer-side thresholding.
+
+Both are pinned by host-buildable C99 tests in `firmware/esp32-csi-node/test/test_vitals_count_presence.c` (`make run_vitals`). The exact thresholds are documented constants pending on-device calibration against ground truth.
+
+### 2026-06 — Rust `wifi-densepose-vitals`: IIR filter NaN/inf self-heal (ADR-158 §A1)
+
+A correctness/safety review of the Rust extraction crate found a real bug parallel to the firmware robustness class above. 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.

- **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<SocketAddr>`) and only honor XFF from an explicit `--trusted-proxy` CIDR — captured as guidance in the test docstrings.

+## Pass 2 — randomized rotation + multi-bit (ADR-156 §8, landed 2026-06)
+
+The "Open question" below ("does `BinaryQuantized` need a randomized
+rotation pre-pass?") is now **answered with measured numbers** via
+ADR-156 §10. Summary:
+
+- **Pass 2 (randomized rotation) is implemented** —
+  `crates/wifi-densepose-ruvector/src/rotation.rs`: a deterministic
+  `R = H·D` (Fast Hadamard Transform + seeded ±1 sign flips), `O(d log d)`
+  / `O(d)`, norm-preserving, reproducible from a stored `u64` seed. Opt-in
+  via `Sketch::from_embedding_rotated` / `SketchBank::with_rotation`;
+  Pass-1 API and wire format unchanged.
+- **Measured top-K coverage** (anisotropic planted-cluster fixture,
+  cosine ground truth, dim=128 N=2048 K=8): rotation lifts coverage
+  **36.13% → 46.39%** at the strict `candidate_k = K` bar, and Pass-2
+  reaches the **≥90% acceptance bar at candidate_k = 24 (~3× over-fetch)**.
+  Multi-bit (≤4-bit) reaches 74% at the strict bar. **Honest verdict:
+  neither rotation nor ≤4-bit multi-bit clears the strict-K 90% bar on
+  this distribution; the bar is met via the over-fetch "candidate set"
+  pattern this ADR specifies** (Decision §"the canonical pattern" — sketch
+  picks the candidate set, full precision refines). Full numbers and
+  reproduce commands in ADR-156 §10.
+- **Pre-existing `SketchBank::topk` bug fixed** — the `n > k` heap path
+  returned the k *farthest* sketches (min-heap mistaken for max-heap);
+  only the `n ≤ k` fast path had test coverage. Fixed + regression-pinned
+  (`topk_heap_path_returns_nearest`,
+  `tight_clusters_give_high_coverage_with_overfetch`). This makes every
+  prior top-K acceptance number in this ADR depend on the fixed path; the
+  ≥90% coverage criterion is only meaningful post-fix.
+
+## Pass 2b — RaBitQ unbiased distance estimator (ADR-156 §11, landed 2026-06)
+
+The **real** RaBitQ contribution (Gao & Long, SIGMOD 2024) — an
+**unbiased estimator of the inner product / distance** from the 1-bit
+code + per-vector side info, not just sign bits — is now implemented and
+**MEASURED against this ADR's ≥90% strict-K bar**:
+
+- **Implemented** — `crates/wifi-densepose-ruvector/src/estimator.rs`:
+  `EstimatorSketch` (Pass-2 sign code + 8 B/vec side info:
+  `residual_norm` + `x_dot_o = ⟨x̄, o'⟩`), `DistanceEstimator`
+  (`⟨o',q'⟩ ≈ ⟨x̄,q'⟩ / x_dot_o`, the paper's unbiased rescale), and
+  `EstimatorBank` reranking candidates by the estimate instead of raw
+  Hamming. **Zero-centroid simplification** (`c = 0`) documented;
+  paper-faithful centroid path also built (`with_centroid`). Additive —
+  Pass-1/Pass-2 and the wire format are unchanged.
+- **MEASURED strict-K coverage** (same fixture as §"Pass 2", 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, but **still ~40 pp short of the ≥90% strict bar.**
+  At over-fetch the estimator does better than sign (95.12% vs 91.60% at
+  candidate_k = 24). **Honest verdict: 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 ≥90% acceptance bar is still met only via the over-fetch
+  "candidate set" pattern this ADR's Decision specifies; the estimator
+  **reduces the over-fetch factor** needed but does not remove it. This
+  is a **published negative**, reported as such. Full numbers + reproduce

+Beyond-SOTA crypto+security review of the SHA-256 + Ed25519 witness chain
+(`witness.rs` / `witness_signing.rs`) and the manifest signature surface
+(`manifest.rs`), because ADR-262 P2 proposes to **reuse this exact signing
+chain**. 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. Not a forgery fix — the verifying
+  key is caller-pinned, never read from the event.
+
+- **Confirmed clean (with evidence):** verify-before-trust + key-pinning
+  (`verify_signature` takes the verifying key as a parameter; `read_jsonl`
+  re-derives every hash and chain-verifies); key handling (the crate never
+  generates/stores/logs/serializes a signing key — only a documented test-only
+  fixed seed; production keys come from the Seed secure store, out of scope);
+  determinism (positional bytes, deterministic Ed25519, alphabetically-locked
+  JSONL field order, sorted TXT records — no HashMap/float nondeterminism feeds
+  any digest); fail-closed parsing (structured errors, no panics; `main.rs`
+  reads no untrusted files/paths).
+
+Tests: `cog-ha-matter --no-default-features` 64 → **68**, 0 failed (CHM-WIT-01
+pinned by 4 fails-on-old tests across `witness.rs`/`witness_signing.rs`;

+service/entity registries every other HOMECORE module trusts. Same rigor as

+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

+- **HC-EID-LEN-01 (unbounded `entity_id` — memory-DoS at the REST boundary).

+  `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. Every `tokio::sync::RwLock`
+  guard in `registry.rs`/`service.rs` is used in a single 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
+  (non-await) broadcast send — safe.
+- **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.

+## 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. Service authorization itself is enforced at the `homecore` service-registry boundary (out of this crate's scope); no gap found in what the automation crate enforces.
+- **Panic-on-config (parse)** — `serde_yaml`/`serde_json` deserialization returns structured `AutomationError` (no `unwrap`/`expect`/index reachable from a crafted config in the eval/exec path); the only remaining panic surface was the `from_secs_f64` path fixed as HC-SEC-02.
+
+Validation: `cargo test -p homecore-automation --no-default-features` → 54 passed / 0 failed (+14 over baseline). Python deterministic proof unchanged (homecore-automation is off the signal-processing proof path).

+
+## 1. 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**. A panel may show an empty/typed-error state when its upstream is down, but it must never silently render fabricated data.
+
+---
+
+## 3. Design system — Cognitum platform conventions
+
+The implementor **must study `https://seed.cognitum.one/store` as the definitive design reference before writing a single line of CSS.** The existing platform's design tokens, extracted from production, are:
+
+### 3.1 Colour palette (CSS custom properties)
+
+| Token | Value | Role |
+|---|---|---|
+| `--bg` | `#0a0e1a` | page background (very dark navy) |
+| `--bg2` | `#111627` | secondary background / nav strip |
+| `--card` | `#171d30` | card / panel surface |
+| `--card-h` | `#1e2540` | card hover state |
+| `--border` | `#252d45` | all border strokes (≈0.67px, subtle) |
+| `--t1` | `#e0e4f0` | primary text (near-white) |
+| `--t2` | `#8890a8` | secondary / muted text |
+| `--t3` | `#505872` | tertiary / disabled text |
+| `--cyan` | `#4ecdc4` | primary action colour (Install buttons, live indicators, accents) |
+| `--cyan-d` | `rgba(78,205,196,0.15)` | cyan tint background for status badges |
+| `--green` | `#6bcb77` | success / online / healthy states |
+| `--green-d` | `rgba(107,203,119,0.15)` | green tint background |
+| `--amber` | `#d4a574` | warning / stale / degraded states |
+| `--amber-d` | `rgba(212,165,116,0.15)` | amber tint background |
+| `--red` | `#e06060` | error / offline / veto states |
+| `--red-d` | `rgba(224,96,96,0.15)` | red tint background |
+| `--purple` | `#a78bfa` | informational / epoch / chain indicators |
+| `--purple-d` | `rgba(167,139,250,0.15)` | purple tint background |
+| `--r` | `10px` | standard border radius on all cards and panels |
+
+### 3.2 Typography
+
+- `--font`: `'Segoe UI', system-ui, -apple-system, sans-serif` — all body and heading text.
+- `--mono`: `'Cascadia Code', 'Fira Code', Consolas, monospace` — all entity IDs, API endpoints, hex values, JSON payloads, COG binary hashes.
+
+### 3.3 Component patterns (from the live Cog Store and API Explorer)
+
+- **Cards**: `background: var(--card)`, `border: 0.67px solid var(--border)`, `border-radius: var(--r)`, `padding: 24px`.
+- **Category pills / status badges**: small `border-radius: 4–6px`, uppercase text, coloured background tint (e.g. `background: var(--cyan-d); color: var(--cyan)` for `RUNNING`; `background: var(--amber-d); color: var(--amber)` for `STALE`).
+- **Primary action buttons**: `background: var(--cyan)`, `color: var(--bg)`, no border — matching the existing "Install" button style exactly.
+- **Secondary / ghost buttons**: transparent background, `border: 1px solid var(--border)`, `color: var(--t1)` — matching the existing "Details" button style.
+- **Nav strip**: `background: var(--bg2)`, text items in `--t2`, active item highlighted in `--cyan` with a bottom underline.
+- **Featured card gradient borders**: top-edge linear gradient from `var(--cyan)` to `var(--purple)` — replicate for HOMECORE section headers.
+- **Live metric cards** (API Explorer status page): icon + large numeric value in `--cyan` or `--green`, label in `--t2` below, on a `var(--card)` background.
+- **Method badge pills** on the API Explorer (`GET` in green, `POST` in amber, `AUTH` in purple) — reuse this same pill system for COG status indicators.
+
+The implementor **must not introduce new colours, typefaces, or border radii.** Every component should feel like it was built by the same team that built the Cog Store and the API Explorer. A user navigating from the Cog Store into the HOMECORE dashboard should not notice a visual seam.
+
+---
+
+## 4. 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<EntityId, Arc<State>>`) 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=<room_id>` 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.

+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` |

+| 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). This adds a network hop, a place for upstream timeouts/partial failures to surface, and a server-side store of SEED bearer tokens that must be protected (§11.10). Each proxied route needs an explicit timeout + typed error mapping so one slow SEED cannot stall the dashboard.
+- Several panels depend on data that only exists on **real hardware or new daemons** (SEED device tier, appliance host metrics, COG supervisor). Until those upstreams exist the corresponding gateway routes return `503 upstream_unavailable`; this is honest but means the dashboard is only as "live" as the tiers behind it (§11 classifies every endpoint by what it depends on).
+- Faithfully mirroring `seed.cognitum.one/store` couples HOMECORE-UI to the external Cog Store's evolving design; token drift there must be tracked and re-synced.
+- The two-tier mental model (Appliance root, SEED children, ESP32 leaves) must be enforced consistently; any panel that flattens or peers the tiers undermines the core architectural constraint.

+
+## 10. Implementation status
+
+Implemented as a zero-dependency, no-build-step vanilla TS/JS + CSS frontend served by `homecore-server` at `/homecore` (the `rufield-viewer` "Axum + vanilla-JS" pattern). The complete deliverable per §2/§7 — all ten panels, fully rendered, wired to live data where the backing service exists and to a contract-conformant DEMO-flagged mock layer (§7.1) where it does not.
+
+**Location:** `v2/crates/homecore-server/ui/` — `css/tokens.css` (the §3.1 palette, verbatim) + `css/app.css` (§3.3 components); `js/{ui,api,ws,mock,app}.js` (shared helpers, REST client, `subscribe_events` WS client, mock layer, shell+router); `js/panels/*.js` (one module per §4 panel). Mounted via `tower-http` `ServeDir` in `homecore-server::build_app`, gated by `--ui-dir`/`HOMECORE_UI_DIR`.
+
+**Verification:**
+- **Rust** — `#[cfg(test)] mod ui_tests` in `homecore-server/src/main.rs`: 5 integration tests (`tower::oneshot`) covering index, design tokens, all ten panel modules served, API coexistence, and mount-disable. *Written but not compiled in the authoring environment (no Rust toolchain present); run `cargo test -p homecore-server` on a Rust host before merge.*
+- **Frontend** — `ui/` test suite under plain `node` (no npm install): `npm test` → import/export graph verifier (15 modules) + render-smoke (executes every panel against a DOM shim; 21 checks) + interaction suite (live WS patch, ws.js handshake/parse, calibration contract; 3 checks). **24/24 green.**
+- **Benchmark** — `npm run bench`: total bundle **136.8 KB** uncompressed (**~37× smaller** than HA's ~5 MB Lit bundle, the ADR-126 §1.1 foil); slowest panel **1.5 ms/cold-render**.
+
+**Honest scope — current vs. target.** *Earlier cut:* the front-end was complete but only §4.4 Entities was wired to a real backend; the rest rendered from an in-browser mock. *This revision implements the §11 wiring:*
+
+- **Front-end (§11.11) — DONE and verified.** `api.js` rewritten: all data accessors are async and call the §11.2 gateway routes; the mock layer is demoted to a dev-only fixture reachable **only** under `?demo=1` / `HOMECORE_UI_DEMO` (§2.2); every panel `await`s and renders a typed empty/error state on failure (no mock fallback in production). All ten panels converted (3 by hand, 7 via parallel agents). Verified under Node: 5 test 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 asserts every panel renders an error state, never mock, never throws** (it caught and fixed a real unhandled-rejection in the events panel).
+- **Gateway (§11.1–§11.6) — IMPLEMENTED, COMPILED, TESTED, RUN.** New `homecore-server/src/gateway.rs` (+`reqwest` dep, +CLI/env flags `--calibration-url`/`--calibration-token`/`--apps-dir`/`--gateway-timeout-ms`, merged into `build_app` via `gateway_router`). Real handlers: `/api/cal/*` reverse-proxy (W2), `GET /api/homecore/rooms` with the §11.3 RoomState adapter (W2), `GET /api/homecore/cogs` supervisor over the apps dir (W4), `GET /api/homecore/appliance` from `/proc` + port probes (W6). SEED-device/appliance-daemon routes (seeds, federation, witness, privacy, settings, automations, events-history, hailo, tokens — W3/W5) return a typed `503 upstream_unavailable` per §11.2. **Verified on Rust 1.89: `cargo test -p homecore-server --no-default-features` = 12/12 pass** (6 gateway + 6 UI mount). **Run live:** `GET /api/homecore/appliance` returns real `/proc` metrics + TCP service probes; unauth → `401`; `cogs` → `[]` with 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` correctly adapts `RoomState` to the UI shape (`breathing`→`breathing_bpm`, `heartbeat:null`→`heart_bpm:null`, injected `anomaly.threshold`/`room_id`, `stale` passthrough). **Live testing caught + fixed one real bug** — a double-`v1` path in the `/api/cal/*` proxy URL.
+
+The endpoint-by-endpoint contract is **§11**; the staged plan and which endpoints depend on real SEED/appliance hardware vs. pure software is **§12**.
+
+---
+
+## 11. Backend wiring — making every panel real
+
+This section is the authoritative contract for full functionality. It removes the mock layer from the production path (§2.2) by routing every panel through the `homecore-server` BFF gateway (§2.1). Each endpoint is classified by what it depends on:
+
+- **EXISTS** — backend code already in this repo; gateway only proxies/adapts.
+- **NEW-GW** — pure software the gateway itself implements (filesystem, `/proc`, process control, recorder query) — no new external service.
+- **NEW-API** — a small HTTP wrapper to add to an existing in-repo crate (`homecore-api`, `homecore-automation`).
+- **SEED-DEV** — depends on a SEED node's on-device HTTPS API (separate hardware/firmware).
+- **APPLIANCE** — depends on an appliance daemon / accelerator stat source.
+
+### 11.1 Gateway shape
+
+`homecore-server` already mounts `homecore-api` at `/api/*` and the UI at `/homecore`. It gains a new **`/api/homecore/*`** namespace (the dashboard-specific aggregation surface) plus a **`/api/cal/*`** reverse-proxy to the calibration service. The browser issues only same-origin requests; the gateway fans out server-side, holding all upstream credentials (§11.10). Every proxied route has an explicit timeout and maps upstream failure to a typed body (`503 upstream_unavailable`, `504 upstream_timeout`) so one slow tier never stalls the dashboard.

+
+### 11.3 Calibration proxy + RoomState adapter
+
+The calibration service is real but on a different binary/port; the gateway reverse-proxies it under `/api/cal/*` (upstream base from `HOMECORE_CALIBRATION_URL`). Its `RoomState` (`wifi-densepose-calibration/src/runtime.rs`) does **not** match the UI's shape, so the gateway adapts it in `GET /api/homecore/rooms`:
+
+| Real field (`RoomState`) | UI field | Adapter rule |
+|---|---|---|
+| `breathing: Option<SpecialistReading>` | `breathing_bpm: {value,confidence}\|null` | rename; `value`=`reading.value`, `confidence`=`reading.confidence`; `None`→`null` (preserves "not trained") |
+| `heartbeat: Option<…>` | `heart_bpm: {…}\|null` | rename `heartbeat`→`heart_bpm` |
+| `presence/posture/restlessness` | same names `{value,confidence}\|null` | `posture.value`=`reading.label` (class), else numeric |
+| `anomaly: Option<…>` | `anomaly: {value,confidence,threshold}` | inject `threshold`=`MixtureOfSpecialists.veto_threshold` (0.5) |
+| `vetoed` / `stale` | `vetoed` / `stale` | pass through (drives the §4.5/§6 banners) |
+| *(absent)* | `room_id`, `seeds[]` | injected by the gateway from the **room registry** |
+
+A **room registry** (config or derived from `GET /api/cal/v1/calibration/baselines`) maps each `room_id` → bank name + serving SEED ids, so `GET /api/homecore/rooms` returns one adapted record per room. `Option::None` → JSON `null` keeps the null-vs-withheld distinction (§6 invariant 3) intact end-to-end.
+
+### 11.4 SEED registry & device-API proxy
+
+The gateway holds a **SEED registry** (`device_id` → base URL + bearer token + zone), populated by pairing (§4.10) and persisted server-side. `GET /api/homecore/seeds[/:id]` fans out to each SEED's on-device API and shapes the result to the §4.2 card/detail model. Expected SEED-side endpoints (the contract the SEED firmware must satisfy — a subset of its 98 endpoints): health; vector-store stats (`vector_count`, `dim`, `epoch`, `knn_latency_ms`, ingest rate); witness (`len`, `last_verify`, `valid`) + `POST verify`; onboard sensors (BME280/PIR/reed/ADS1115/vibration); reflex rules + thresholds; cognitive analysis (fragility, coherence phases); ingest feeders (ESP32 node ids + packet type `0xC5110003`/`0xC5110002` + rate). Offline/unreachable SEEDs surface as `online:false` (drives the §4.1 red tint) rather than failing the whole list.
+
+### 11.5 Appliance metrics collector (§4.1)
+
+`GET /api/homecore/appliance`, implemented in the gateway: CPU/RAM/uptime from `/proc`; Hailo load + temperature from the Hailo runtime/sysfs (or `ruvector-hailo-worker` stats); service health by probing `ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`; event-bus rate from the `homecore` broadcast channel + its lag counter (already exposed for §4.1/§4.4).
+
+### 11.6 COG supervisor (§4.6)
+
+`GET /api/homecore/cogs`: read each `/var/lib/cognitum/apps/*/manifest.json` ([ADR-100](ADR-100-cog-packaging-specification.md)), the pid file, and verify `binary_sha256` + `binary_signature` (Ed25519) → status/shield. `POST …/cogs/:id/{start,stop,restart}` performs supervised process control; `GET …/cogs/:id/logs` tails `output.log`/`error.log`; `GET/PUT …/cogs/:id/config` reads/writes `config.json`. Hailo-arch COGs join the §11.5 Hailo stats. The Cog Store/App-Registry **browsing** panel was removed per product decision; this is operational management only.
+
+### 11.7 Witness aggregation + privacy (§4.9)
+
+`GET /api/homecore/witness` merges two chains chronologically: the `homecore` Ed25519 state-transition chain (exposed by a small `homecore-api` route over its witness log) and each paired SEED's SHA-256 ingest chain (proxied via the registry), paginated server-side. `GET/POST /api/homecore/privacy` reads/sets per-SEED privacy mode via the SEED privacy control plane ([ADR-141](ADR-141-bfld-privacy-control-plane-modes-attestation.md)) — the POST is the high-stakes confirmed toggle (§4.9). `GET /api/homecore/witness/export` packages both chains into the downloadable attestation bundle.
+
+### 11.8 Event history + automation CRUD (§4.8)
+
+`homecore-api` adds `GET /api/events?since=…` backed by `homecore-recorder` ([ADR-132](ADR-132-homecore-recorder-history-semantic-search.md)) for history (live updates continue over the existing WS). The automation builder persists through `GET/POST/DELETE /api/homecore/automations`, a thin HTTP wrapper over the `homecore-automation` engine's register/list/remove ([ADR-129](ADR-129-homecore-automation-engine.md)). RuView-specific triggers (RoomState thresholds, SEED reflex events) map onto the engine's trigger types.
+
+### 11.9 Entity provenance convention (§4.4/§6)
+
+The first-class provenance badge requires each entity to carry its lineage. Convention: every integration writes `attributes.source` (and, where known, `attributes.seed` / `attributes.cog`) when it sets state; `cog-ha-matter` ([ADR-116](ADR-116-cog-ha-matter-seed.md)) populates these from the ESP32 node → SEED → COG path and HA `via_device`. The gateway/UI resolves node→seed→cog from these attributes (no fabrication; missing lineage renders as "unknown", not invented).
+
+### 11.10 Auth, credentials, config
+
+- **Browser → gateway:** one long-lived access token (the §4.10 LLAT), sent as `Authorization: Bearer`; validated by `homecore-api`'s `LongLivedTokenStore`. The dev default (`allow_any_non_empty`) stays for local runs; production provisions `HOMECORE_TOKENS`.
+- **Gateway → upstreams:** SEED bearer tokens and the calibration token live **only** server-side (SEED registry + `HOMECORE_CALIBRATION_TOKEN`); never sent to the browser. This is the reason the gateway exists.
+- **Config:** `HOMECORE_CALIBRATION_URL`, SEED registry store path, per-proxy timeout (default 2 s), `HOMECORE_UI_DEMO` (dev fixture). No browser CORS needed (same origin); gateway→upstream is server-to-server.
+
+### 11.11 Front-end changes
+
+`api.js`: drop the mock fallback from the production path — methods call the §11.2 gateway routes; `this.base` stays same-origin; the mock layer is reachable only under `?demo=1`/`HOMECORE_UI_DEMO`. Every panel renders a **typed empty/error state** (not mock) when its route returns `503/504`. `mock.js` moves to a dev fixture (kept for the offline test harness, excluded from the production bundle). The §10 frontend tests are re-pointed at the gateway contract (and gain contract tests per §11.2 route).
+
+---
+
+## 12. Delivery plan to full functionality
+
+Staged so each wave is independently shippable behind the gateway, lands real data for a coherent set of panels, and has an explicit acceptance gate. "Class" reuses §11's tags.
+
+| Wave | Scope | Class | Acceptance gate |
+|---|---|---|---|
+| **W1 — Gateway foundation** | `/api/homecore/*` scaffold in `homecore-server`; auth passthrough; per-proxy timeout + typed errors; `api.js` base + remove prod mock (`?demo=1` only); panels get typed empty/error states | NEW-GW | Entities + live WS still green; with no upstreams, every other panel shows "upstream unavailable", **never** mock (unless `?demo=1`); Rust + JS suites pass |
+| **W2 — Rooms + Calibration** | `/api/cal/*` reverse-proxy; `GET /api/homecore/rooms` with the §11.3 RoomState adapter + room registry; wire §4.5 + the §4.7 wizard to real endpoints; delete the in-browser calibration stub | EXISTS (proxy+adapter) | Against a running `calibrate-serve` (replayed CSI), the wizard drives a real baseline→enroll→train→verify and §4.5 shows real `RoomState` with correct stale/veto/null mapping; contract test on the adapter |
+| **W3 — Events + Automations** | `GET /api/events` over `homecore-recorder`; `/api/homecore/automations` over `homecore-automation` | NEW-API | §4.8 history loads from recorder; an automation created in the UI persists and fires via the engine |
+| **W4 — COG management** | `/api/homecore/cogs*` supervisor over `/var/lib/cognitum/apps/` (manifest + pid + sig verify + logs + config) | NEW-GW | §4.6 lists real installed COGs; start/stop/restart works; sha256/signature shield reflects real verification; logs tail |
+| **W5 — SEED tier** | SEED registry + pairing; `/api/homecore/seeds*` device proxy; witness merge + privacy control; ESP32 provisioning | SEED-DEV | Against a real or emulated SEED API, §4.2/§4.3/§4.9/§4.10 show real vector-store/witness/sensor/reflex/cognition data; SEED tokens stay server-side; offline SEED → red tint, not a failed page |
+| **W6 — Appliance + federation + Hailo** | `/api/homecore/appliance` (host metrics + service probes); `/api/homecore/hailo`; `/api/homecore/federation` ([ADR-105](ADR-105-federated-csi-training.md)) | NEW-GW + APPLIANCE | §4.1 health is real; §4.6 Hailo HEF/throughput real; §4.3 federation round/coordinator/Krum real |
+
+**Definition of done (full functionality):** with W1–W6 merged and the upstream tiers running, loading `/homecore` with **no** `?demo=1` flag shows live data on all ten panels, `api.anyDemo()` is false, and no panel renders fabricated values. Panels whose tier is offline show typed empty/error states. The mock layer is reachable only as the `?demo=1` developer fixture.
+
+### 12.1 Wave status (this revision)
+
+| Wave | Status |
+|---|---|
+| **W1 — Gateway foundation** | ✅ DONE — `gateway.rs`, auth passthrough, typed `503/504`, merged into `build_app`; front-end mock removed from prod path + `?demo=1` fixture; typed error states. **Compiled + 12/12 Rust tests + JS suite green + run live.** |
+| **W2 — Rooms + Calibration** | ✅ DONE — `/api/cal/*` reverse-proxy + `GET /api/homecore/rooms` RoomState adapter; front-end calibration stub deleted (now proxies the real API). **Proven live against a calibration upstream** (proxy 200 + adapted shape); null-preservation unit-tested. |
+| **W3 — Events + Automations** | ⏳ gateway returns typed `503` (recorder/automation HTTP wrappers pending); front-end handles it gracefully (history note, builder still usable). |
+| **W4 — COG management** | ✅ supervisor DONE — lists `/var/lib/cognitum/apps/` manifests + pid liveness (returns `[]` live with no apps dir); start/stop/log/config control is the remaining follow-up. |
+| **W5 — SEED tier** | ⏳ gateway returns typed `503` (SEED registry + device proxy pending real/emulated SEED hardware). |
+| **W6 — Appliance + federation + Hailo** | ◑ appliance host metrics from `/proc` + port probes DONE (live `/proc` data verified); Hailo stats + federation remain `503` (need the accelerator stat source / coordinator). |
+
+**Status:** the gateway is **compiled and tested on Rust 1.89** (`cargo test -p homecore-server` = 12/12) and was **run live** (curl proof in §10). The one remaining caveat is intrinsic, not an environment limit: **W3/W5/W6-Hailo/federation depend on services/hardware that are not in this repo** (recorder/automation HTTP wrappers, real SEED nodes, the Hailo stat source), so they return honest typed `503`s and the UI shows error states — exactly as §2.2/§11.2 prescribe. W1/W2/W4/W6-appliance are functional now.
+
+### 12.2 Security review (PR #1082)
+
+A high-effort public-PR review of the merged gateway + front-end surfaced the following, all fixed and pinned by tests (`cargo test -p homecore-server` is now **18/18**):
+
+| # | Severity | Finding | Fix |
+|---|---|---|---|
+| 1 | **HIGH** | **Path-traversal / confused-deputy SSRF** in the `/api/cal/*` reverse-proxy. The wildcard path was interpolated into the upstream URL while `proxy()` attaches the privileged server-side calibration bearer, so `/api/cal/v1/../../x` (or `..%2f`, `%2e%2e`, leading `/`, `\`, double-encoded `%252e`) could escape the `…/api/` scope **with the token**. | `validate_proxy_path()` decode-then-checks and rejects absolute / backslash / dot-segment / encoded-traversal paths with a typed **400 before the URL is built** (GET **and** POST); legit `v1/...` paths still pass. |
+| 2 | Correctness | **CORS + tracing didn't cover gateway routes** — `/api/homecore/*` + `/api/cal/*` were `.merge()`d outside `homecore-api::router()`'s layers. | The audited HC-05 `build_cors_layer()` + `TraceLayer` are now applied to the whole merged app in `main.rs`. |
+| 3 | Honesty (§6) | **Fabricated data** — hardcoded `anomaly.threshold: 0.5` in the adapter; dashboard rendered `"null%"`/`"null°C"`; COG Hailo pill hardcoded `"connected"`; `rooms.js` defaulted a null threshold to `0.8`. | Threshold passes through the real upstream value or emits `null` (withheld); dashboard renders `—`; the Hailo pill reflects the real appliance probe; the UI treats a null threshold as withheld. |
+| 4 | Robustness | A string `hef` (forwarded verbatim) threw on `.forEach`/`.join`; `frames/target` could be `NaN%`/`Infinity%`; calibration Restart leaked the baseline `setTimeout` poll. | `asArray()` coercion; `target > 0` guard; cancellable poll cleared on Restart / panel teardown. |
+| 5 | Perf | Sequential per-bank RoomState fetches; blocking `std::net::TcpStream::connect_timeout` probes on an async handler; `mock.js` statically bundled. | Concurrent `futures::join_all`; async `tokio::net::TcpStream` + `timeout`; demo-only dynamic `import()` of `mock.js`. |
+
+**Known limitations carried forward (not regressions):**
+- **`reqwest` rustls-only is a workspace-wide concern.** `homecore-server` opts into `rustls-tls` only, but cargo feature-unification means any sibling crate enabling the default `native-tls` re-introduces OpenSSL into the final binary. A true "no OpenSSL on the appliance" guarantee requires aligning **every** reqwest-pulling crate on rustls-only — out of scope for this PR; documented at the dependency in `Cargo.toml`.
+- **DEV-mode auth.** When `HOMECORE_TOKENS` is unset, the token store falls back to `allow_any_non_empty()` (any non-empty bearer accepted) on `0.0.0.0`. This is pre-existing and intentionally **unchanged** here; the loud boot `warn!` is retained. Provision real tokens (`HOMECORE_TOKENS=…`) before exposing the server to a network.

+
+---
+
+## 1. 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.
+- **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. Python deterministic proof unchanged (recorder is off the signal proof path).

+## 6. 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). There is **no** `std::process` / `tokio::process`
+  / `Command` / process `.spawn()` anywhere in the crate — the trait `spawn` is
+  only 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 (P2). Defence-in-depth: 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. Pins:
+  `shell_metachars_never_survive_into_a_resolved_slot`,
+  `runner_opts_are_inert_no_process_spawned`,
+  `pipeline_injection_shaped_utterance_carries_no_metachars_to_service`.
+- **ReDoS — STRUCTURALLY IMPOSSIBLE.** `regex 1.12.3` (no `fancy-regex` in the
+  dependency tree) is linear-time; a classic `(a+)+$` shape on adversarial input
+  completes in bounded time. Pin:
+  `pathological_backtracking_pattern_completes_in_bounded_time`. Patterns are
+  operator-registered, not user-supplied, in any case.
+- **NaN-poisoning — EMBEDDINGS STRUCTURALLY FINITE.** The embedding path takes
+  only `&str` and produces values via FNV feature-hashing + a guarded L2
+  normalise (`norm > 1e-12`); no external float input, no unguarded division, so
+  a crafted utterance cannot inject NaN/Inf to poison the cosine k-NN. Cosine
+  against the zero vector is a finite `0.0`; an empty index `max_by` returns
+  `None` (no panic); the NaN-safe `partial_cmp().unwrap_or(Equal)` is already in
+  place. Pins: `embeddings_are_structurally_finite`,
+  `cosine_with_zero_vector_is_finite_not_nan`,
+  `empty_utterance_against_empty_index_no_panic_no_match`.
+- **Intent confusion / fail-closed.** An unrecognised utterance → `not_understood()`
+  (no service call); a recognised intent with no registered handler →
+  `not_understood()`; semantic below-threshold / empty-index → regex fallback.
+  No default high-privilege intent, no fail-open path.
+- **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 exemplar `Vec` (no remove API), so it is always in bounds.

+## Witness Integrity Review (2026-06-14) — domain-separation fix
+
+A beyond-SOTA security review of `wifi-densepose-engine` (the composition root
+that builds the §2.7 trust witness in `witness_of`) found a real **witness
+domain-separation gap**, now fixed.
+
+**Finding (witness-gap, HIGH).** `witness_of` concatenated `model_version`,
+`calibration_version`, and `privacy_decision` boundary-to-boundary, and the
+variable-length `evidence` list carried no explicit count. A string straddling a
+field boundary therefore collided with a *different* trust decision —
+e.g. a per-room adapter id (ADR-150 §3.4, operator-influenceable) that absorbs
+the leading bytes of the calibration epoch (`model="…cal:00a"`, `cal="b"`)
+produces the **same** witness as `model="…"`, `cal="cal:00ab"`. Two distinct
+privacy-relevant input tuples → one witness defeats the "any privacy-relevant
+delta → different witness" guarantee this ADR's §2.7 witness exists to provide.
+
+**Fix.** The witness now (a) prepends a domain tag `ruview.engine.witness.v1`,
+(b) writes an explicit 8-byte evidence count, and (c) **length-prefixes every
+field** (8-byte LE length ‖ bytes), so field framing is unambiguous regardless
+of contents. This is a witness-layout change (all prior witness bytes are
+invalidated by design); downstream consumers only assert witness *relationships*
+(`assert_ne`/`assert_eq` across runs), not absolute bytes, so nothing breaks.
+
+Pinned by `witness_distinguishes_model_calibration_boundary` and
+`witness_distinguishes_evidence_model_boundary` (both fail on the old
+concatenation). Witness **determinism** was reviewed and confirmed clean: no
+HashMap iteration and no float formatting feed the hash (floats appear only in
+the `SemanticState` statement, which is outside the witness).

+## Privacy Monotonicity Review (2026-06-14) — confirmed clean
+
+A beyond-SOTA security review of the governed-trust cycle
+(`wifi-densepose-engine::StreamingEngine::process_cycle_calibrated`) examined
+the privacy-demotion path this ADR governs. **The monotonicity invariant holds:
+demotion only ever makes the emitted class more restrictive, never less.**
+
+Verification (no behaviour change, the result is a clean bill with evidence):
+
+- Each cycle computes `effective_class` fresh from the active mode's
+  `target_class()` (the floor) and applies at most a **single-step** demotion
+  (`demote_one`, clamped at `Restricted`). There is no cross-cycle state that
+  could let a permissive class overwrite a restrictive one.
+- A forced contradiction (calibration mismatch / array-geometry insufficiency /
+  mesh partition risk, ADR-032) raises the class byte; a clean cycle emits
+  exactly the base class.
+- Pinned by `forced_contradiction_never_relaxes_class`, a property test over
+  **all five** `PrivacyMode`s asserting `effective_class.as_u8() >=
+  base_class.as_u8()` (strictly greater unless already clamped at `Restricted`)
+  under a forced contradiction, and `== base` on a clean cycle.
+
+Fail-closed boundaries were also pinned: an empty cycle errors (no degenerate
+over-permissive output, `empty_cycle_fails_closed`) and the single-node boundary
+is characterized as a valid non-demoting mode (`single_node_cycle_is_well_formed`).
+
+The related witness domain-separation fix from the same review is recorded in
+ADR-137 (the witness folds `effective_class`, so the demotion is auditable).
+## Security & Privacy Review (2026-06-14)
+
+Beyond-SOTA privacy+security review of `wifi-densepose-bfld` (the crate was not in the ADR-154–159 sweep). Two real bugs fixed (each pinned by a fails-on-old test), several dimensions confirmed clean.
+
+### Findings
+
+| # | Severity | Site | Issue | Fix | Pinned by |
+|---|----------|------|-------|-----|-----------|
+| 1 | **privacy-bypass (HIGH)** | `pipeline.rs::process_to_frame` | The documented wire-bytes production path stamped the frame header with the active `PrivacyClass` but serialized the caller's `BfldPayload` **unchanged** via `BfldFrame::from_payload` — never routing through `PrivacyGate::demote`. A frame labeled `Anonymous`(2)/`Restricted`(3) carried the full `compressed_angle_matrix` (identity surface) + amplitude/phase + `csi_delta`. A `NetworkSink` accepts class ≥ `Derived`(1), so the identity surface could cross the node boundary despite the restrictive class byte — the byte lied about content. | Apply `PrivacyGate::demote(frame, active_class)` after construction: a same-class transition that strips the sections the class forbids; `Raw`/`Derived` keep the full payload. | `tests/pipeline_to_frame.rs::process_to_frame_at_anonymous_strips_identity_leaky_sections`, `…_in_privacy_mode_strips_amplitude_and_phase` (both FAILED pre-fix); `…_at_derived_preserves_full_payload` (over-strip guard) |
+| 2 | **PII/injection (MEDIUM)** | `mqtt_topics.rs::render_events` | `zone_activity` payload built as `format!("\"{zone}\"")` with no JSON escaping (while `ha_discovery.rs` already escapes). A zone name with `"`/`\` produced malformed/injectable JSON on the HA state topic. | `json_string_literal()` escaper mirroring `ha_discovery::push_str_field`. Value-identical for normal zone names. | `tests/mqtt_topic_routing.rs::zone_payload_escapes_json_metacharacters` (FAILED pre-fix) |
+
+### Dimensions confirmed clean (with evidence)
+
+- **Event-field privacy gating** — `BfldEvent::apply_privacy_gating` nulls `identity_risk_score` + `rf_signature_hash` at `Restricted`, and `serde(skip_serializing_if = "Option::is_none")` omits them entirely. `render_events`/`render_discovery_payloads` refuse class < `Anonymous` (stricter than the `sink.rs` `NetworkKind` `MIN_CLASS = Derived` — defense in depth toward less leakage). Covered by `event_privacy_gating.rs`, `mqtt_topic_routing.rs`, `ha_discovery.rs`.
+- **Witness/hash framing (the engine `witness_of` bug class)** — CLEAN. `SignatureHasher::compute` prefixes a **fixed 4-byte** `day_epoch` then a **fixed-width canonical-f32** feature block (`IdentityFeatures`: Embedding = `EMBEDDING_DIM*4`, RiskFactors = 16 B). `PrivacyAttestationProof::compute` hashes a fixed 32-byte `prev_hash` + three fixed 1-byte values. No variable-length operator-influenceable string is concatenated into any digest — no length-prefix-framing collision is possible.
+- **Fail-closed** — `payload.rs::from_bytes` rejects truncated/overflowing/trailing-byte sections (`checked_add`, bounds checks); `frame.rs::from_bytes` validates magic/version/length/CRC; `PrivacyClass::try_from` rejects unknown bytes; `identity_risk::score` maps NaN/degenerate factors → 0.0 (privacy-conservative). The `from_score(NaN) → Accept` choice is a documented, deliberate publish-aggregate-only fallback (NaN never reaches it from `score()`); risk-driven NaN cannot leak identity because identity gating is class-byte-driven, not risk-driven.
+
+### Observation (not a bug)
+
+The ADR-141 control plane (`PrivacyMode`/`PrivacyModeRegistry`) is **not yet wired into the emit path** — the emitter/pipeline enforce the raw `PrivacyClass` directly; the registry is exported + unit-tested but advisory. This matches the "Integration glue — not yet on the live path" status above. The class-byte enforcement (emitter + event + renderers + the now-fixed `process_to_frame`) is the live guarantee. Wiring the registry is the documented next step.

+Beyond-SOTA correctness+security review of `wifi-densepose-calibration` (this
+ADR's pipeline), un-covered by the ADR-154–159 sweep.
+
+**Finding (FIXED) — NaN-poisoning of the feature path (numerical / fail-closed).**
+`Features::from_series` — the carrier for both live inference and training-anchor
+extraction — computed `mean`/`variance`/`motion` over the raw scalar series with
+no non-finite guard. A single `NaN`/`±inf` sample (corrupt CSI frame) yielded
+`mean=NaN, variance=NaN` and an all-`NaN` prototype embedding. Persisted into a
+`PresenceSpecialist::threshold`/`empty_mean` at train time, the `NaN` **silently
+disabled presence detection** for the bank's lifetime (every `>` / `|·|`
+comparison against `NaN` is false → always reads *absent*, confidence 0), with no
+error — and an asymmetry against the rigorously NaN-guarded `geometry_embedding`.
+Fixed at the production boundary: non-finite samples are dropped (a corrupt frame
+counts as no frame), an all-non-finite series degrades to `Features::ZERO` like
+the empty series. Value-identical for all-finite input (full-loop + extract tests
+unchanged); pinned by `non_finite_samples_do_not_poison_features` and
+`all_non_finite_series_is_zero` (both fail on the old code).
+
+**Clean dimensions (evidence, no invented issues).**
+- *File/path handling:* the crate performs **zero** file/path I/O (no
+  `std::fs`/`Path`/`File`/`read`/`write` in `src/`; only in-memory `serde_json`).
+  Path-traversal / unbounded-read / artifact-path handling live entirely in the
+  `wifi-densepose-cli` consumer (`room.rs`), outside this crate's boundary.
+- *Untrusted-load:* `SpecialistBank::from_json` shape-validates via serde
+  (malformed → `CalibrationError::Serde`); banks are local-first (invariant B),
+  never network-received. A well-formed bank with adversarial numerics is trusted
+  as-is — acceptable under the local-first threat model; a validate-on-load
+  defense-in-depth pass is a possible future hardening, not a present bug.
+- *Receipt/hash integrity:* the crate emits no hash/receipt/witness/signature, so
+  the unframed-concatenation bug class (cf. the engine `witness_of` fix) is
+  structurally absent.
+- *Other numerical paths:* `geometry_embedding` sanitizes every input and sweeps

+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." This ADR answers that with **evidence, not adjectives**:
+
+- Every claimed code improvement ships with a **committed regression test** (correctness) or a **committed criterion bench** (performance).
+- Every perf number below is **MEASURED before/after** with the exact reproduce command. A perf claim without a measured before/after is **UNPROVEN** and is not made here.
+- Every external SOTA reference is graded **MEASURED** / **CLAIMED** / **THEORETICAL**, distinguishing what a paper *measured* from what it *asserts* and from what is merely *plausible*.
+- The headline finding — a **dead CIR coherence gate that silently fell back in production for every canonical frame** — is disclosed in full (§2), not buried.
+
+Test machine for the perf numbers: Windows 11, `cargo bench --release`, criterion 0.5. Numbers are wall-clock medians on this box; they are about **ratios** (before/after), which are stable across machines, not absolute ns.
+
+---
+
+## 1. Context
+
+The RuvSense signal stack (16 `ruvsense/` modules + the classic `features.rs`/`csi_processor.rs`/`spectrogram.rs`/`bvp.rs` pipeline) grew quickly across ADR-014/029/030/134/135. A beyond-SOTA review surfaced ~50 findings ranging from two **critical correctness/security defects** to micro-optimizations and SOTA-gap research items. Milestone 0 closes the **provable, high-leverage subset**: the two criticals, a divide-by-zero trio, two measured perf wins, and the research landscape. The remaining ~45 are catalogued in §7 so the backlog is explicit and auditable.
+
+---
+
+## 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). The gate now decodes 100% of canonical-56 frames where it previously decoded 0%.
+
+---
+
+## 3. The second critical — NaN/inf adversarial-detector bypass (CRITICAL, FIXED)
+
+### 3.1 What was wrong
+
+`AdversarialDetector::check` (adversarial.rs) takes per-link `link_energies: &[f64]`. A single **NaN/inf** entry bypassed the whole detector: every `e > threshold` test is `false` on NaN, the Gini sort used `partial_cmp().unwrap_or(Equal)`, and the final `anomaly_score.clamp(0,1)` returns NaN on a NaN input. A real RF link can never have NaN/inf energy, so a non-finite input is *itself* the strongest possible spoof — yet it could slip through as "clean."
+
+### 3.2 The fix
+
+Finite-validate at the boundary: the first non-finite `link_energies` entry now **short-circuits to a definite anomaly** (`anomaly_detected = true`, `anomaly_score = 1.0`, `affected_links = [bad_idx]`, `FieldModelViolation`), and the poisoned frame is **not** seeded into the temporal-continuity state.
+
+### 3.3 The PROOF
+
+| Test | Asserts |
+|------|---------|
+| `nan_link_energy_flags_anomaly` | a NaN link energy → `anomaly_detected`, score 1.0, affected link reported, `anomaly_count == 1` |
+| `inf_link_energy_flags_anomaly` | both `+inf` and `−inf` → anomaly, score 1.0 |
+
+```bash
+cd v2 && cargo test -p wifi-densepose-signal --no-default-features --lib \
+  ruvsense::adversarial::tests::nan_link ruvsense::adversarial::tests::inf_link
+```
+
+---
+
+## 4. Divide-by-(n−1) window trio (CORRECTNESS, FIXED)
+
+Three windowing helpers divided by `(n − 1)` with no small-`n` guard:
+
+| Site | Bug | Fix |
+|------|-----|-----|
+| `csi_processor.rs` `CsiPreprocessor::hamming_window(n)` | `n=0` underflowed `0usize − 1`; `n=1` divided by 0 → all-NaN window | `match n { 0 => [], 1 => [1.0], _ => … }` |
+| `bvp.rs` Hann window | `window_size=1` divided by 0 → NaN BVP | length-1 guard → constant `[1.0]` |
+| `spectrogram.rs` `make_window` | `size=1` divided by 0 for Hann/Hamming/Blackman | `size <= 1` short-circuit → `vec![1.0; size]` |
+
+The standard convention for a length-1 window is the constant `1.0`; length-0 is empty.
+
+**PROOF:** `test_hamming_window_degenerate_sizes` (csi_processor), `bvp_window_size_one_is_finite` (bvp), `make_window_size_0_and_1_are_safe` (spectrogram) — each asserts finiteness at sizes 0/1/2.
+
+The Python deterministic proof (`archive/v1/data/proof/verify.py`) still prints **VERDICT: PASS** with the **same** pipeline hash `f8e76f21…46f7a` — the reference path uses `n ≥ 2`, so the guard is bit-transparent there.
+
+---
+
+## 5. Measured performance wins (MEASURED before/after; benches committed)
+
+Both changes are **bit-equivalent** (asserted by a committed test) — they only remove wasted work. New criterion benches in `benches/features_bench.rs` (registered in `Cargo.toml`).
+
+**Reproduce both:**
+```bash
+cd v2 && cargo bench -p wifi-densepose-signal --no-default-features --bench features_bench
+# compile-only: append --no-run
+```
+
+### 5.1 FFT-planner caching for PSD (features.rs)
+
+`PowerSpectralDensity::from_csi_data` constructed a fresh `FftPlanner` and re-planned the FFT **on every frame** — and `FeatureExtractor::extract` calls it per frame on the hot path. New `from_csi_data_with_fft(csi, fft_size, &Arc<dyn Fft>)` reuses a plan cached in `FeatureExtractor` (built once in `new()`). Output is **bit-identical** (`psd_cached_fft_bit_identical_to_fresh` compares `f64::to_bits` of values + all summary stats across 6 FFT sizes).
+
+Bench group `psd_fft_planner` — `fresh_planner` (before) vs `cached_planner` (after), per frame:
+
+| fft_size | before (fresh plan), median | after (cached), median | speedup |
+|----------|------------------------------|-------------------------|---------|
+| 64  | 5.84 µs/frame | 1.89 µs/frame | **3.09×** |
+| 128 | 9.31 µs/frame | 3.61 µs/frame | **2.58×** |
+| 256 | 13.77 µs/frame | 6.73 µs/frame | **2.04×** |
+
+Medians from criterion (warm-up 1 s, 20 samples). Raw three-point estimates (low/median/high), per frame:
+`fresh/64 [5.27, 5.84, 6.34] µs` vs `cached/64 [1.76, 1.89, 2.03] µs`;
+`fresh/256 [13.29, 13.77, 14.32] µs` vs `cached/256 [6.26, 6.73, 7.43] µs`.
+The win is the re-planned `FftPlanner` construction the cache hoists out of the per-frame loop; it grows in *relative* terms at small FFTs (planning is a larger fraction of a cheap transform) and stays a flat ~2× at 256.
+
+### 5.2 DTW Sakoe-Chiba band honored (gesture.rs)
+
+`dtw_distance` computed the band bounds `j_start/j_end` but still iterated the **full** `1..=m` row, `continue`-ing on out-of-band cells — so the band constrained the *path* but not the *work* (still O(n·m)). The fix iterates only `j_start..=j_end` (O(n·band)), resetting just the two boundary-guard cells the recurrence can read, and computes the endpoint reachability (`|n−m| ≤ band`) at the return site. Result is **bit-identical** to the full-row version across 12 shapes × 8 band widths (`dtw_banded_bit_identical_to_fullrow`).
+
+Bench group `dtw_sakoe_chiba` — `full_row` (before) vs `banded` (after):
+
+| case | before (full row), median | after (banded), median | speedup |
+|------|-----------------------------|--------------------------|---------|
+| n=m=100, band=5  | 33.45 µs | 13.77 µs | **2.43×** |
+| n=m=200, band=5  | 122.32 µs | 29.55 µs | **4.14×** |
+| n=m=200, band=10 | 159.98 µs | 60.19 µs | **2.66×** |
+
+Medians from criterion (warm-up 1 s, 20 samples). Raw (low/median/high):
+`full_row n200_band5 [107.6, 122.3, 146.5] µs` vs `banded n200_band5 [26.4, 29.5, 33.1] µs`.
+The speedup tracks the inner-loop cell-count ratio `m / (2·band+1)` — n=m=200, band=5 → 200/11 ≈ 18× fewer cells, but euclidean-distance cost and loop overhead dominate at these sizes so the wall-clock win is ~4× (still the **largest at the longest sequence / narrowest band**, exactly as the algorithm predicts). It shrinks toward 1× as the band widens to cover the whole matrix (band=10 → 2.66×), and grows with sequence length (band=5: 2.43× at n=100 → 4.14× at n=200).
+
+> **Note on the other re-plan sites.** `spectrogram.rs`/`bvp.rs` plan their FFT **once per call** and reuse it across all frames/subcarriers (already amortized), so caching there is marginal — deferred (§7). The PSD site was the only one re-planning *per frame*.
+
+---
+
+## 6. Per-module SOTA landscape (evidence-graded)
+
+Grades: **MEASURED** (the source measured it, ideally with public method/code), **CLAIMED** (asserted, no reproducible artifact), **THEORETICAL** (plausible, no published target).
+
+### 6.1 CSI → CIR (cir.rs — our ISTA/L1 sparse recovery)
+
+- **Deep-unfolded ISTA / LISTA for CSI→CIR — MEASURED.** Learned ISTA unrolling reports ~**3 dB NMSE** improvement over classical OMP/FISTA for channel/CIR estimation (arXiv [2211.15440](https://arxiv.org/abs/2211.15440); survey [2502.05952](https://arxiv.org/abs/2502.05952)). Public methods; numbers measured in-paper. **This is our #1 future item (§7) — our `cir.rs` already builds the sub-DFT Φ that LISTA would make trainable.**
+- **Diffusion CIR prior — MEASURED (artifact).** [github.com/benediktfesl/Diffusion_channel_est](https://github.com/benediktfesl/Diffusion_channel_est) ships **public weights** for a diffusion-model channel-estimation prior. Heavier than our edge budget; tracked, not adopted.
+- **Coherence gating (the §2 gate) — THEORETICAL.** Our 0.7/0.3 freq/CIR blend is an engineering heuristic with no published accuracy target; now that it *runs*, it can finally be A/B-measured.
+
+### 6.2 Adversarial robustness (adversarial.rs)
+
+- **Adversarial-robustness eval for WiFi sensing — MEASURED.** arXiv [2511.20456](https://arxiv.org/abs/2511.20456) + the **Wi-Spoof** benchmark provide a measured evaluation protocol for spoofed/injected CSI. Our detector's physical-plausibility checks (consistency/Gini/temporal/energy) are in the same spirit; adopting Wi-Spoof as an external benchmark is a §7 item. (The §3 NaN fix is a precondition: a detector that NaN-bypasses can't be benchmarked honestly.)
+
+### 6.3 Multi-AP / multistatic fusion (multistatic.rs)
+
+- **Bayesian multi-AP fusion — CLAIMED.** arXiv [2512.02462](https://arxiv.org/abs/2512.02462) proposes a Bayesian fusion across APs; **no code released**, numbers self-reported. Our attention-weighted fusion is a different (cheaper) mechanism; tracked as a comparison target, not adopted.
+
+### 6.4 RF intention-lead / pre-movement (intention.rs) — THEORETICAL
+
+The 200–500 ms pre-movement "lead signal" framing has **no published commodity-WiFi target** we can grade. Honestly THEORETICAL; no work item.
+
+---
+
+## 7. Decision, roadmap, and the deferred-findings backlog
+
+### 7.1 Accepted now (this milestone)
+
+The §2–§5 fixes are **ACCEPTED and committed**: dead CIR gate fixed, NaN bypass fixed, window trio fixed, calibration dead-branch de-misled, two measured perf wins. All `cargo test -p wifi-densepose-signal --no-default-features` (and `--features cir`) green; Python proof PASS.
+
+### 7.2 Top accepted-future item — LISTA-for-CIR (NOT implemented here)
+
+**Unroll the existing ISTA in `cir.rs` into trainable layers (LISTA).** Effort: **M**. The sensing matrix Φ and the ISTA recurrence already exist; LISTA replaces the fixed step size / threshold with per-layer learned parameters over a fixed unroll depth. Measured target to beat: **~3 dB NMSE over OMP/FISTA** (arXiv 2211.15440 — MEASURED). Proposed, not built in Milestone 0.
+
+### 7.3 Other graded-future items
+
+- Adopt **Wi-Spoof** (arXiv 2511.20456, MEASURED) as the external adversarial benchmark for `adversarial.rs`.
+- Evaluate the **diffusion CIR prior** (public weights, MEASURED) as an offline quality ceiling — *not* an edge target.
+- Bayesian multi-AP fusion (2512.02462, CLAIMED) — comparison only, pending released code.
+
+### 7.4 Deferred Milestone-0 review findings (explicit backlog)
+
+Catalogued so nothing is silently dropped. Priority: **P1** correctness-adjacent, **P2** perf, **P3** clarity/style.
+
+**Milestone-1 update (2026-06-13):** the **four P1 backlog items** (#1, #9, #10, #13) are now cleared — #1 and #10 **RESOLVED (MEASURED)**, #9 and #13 **RESOLVED-PARTIAL (DATA-GATED:** de-magicked + boundary-tested, operating values unchanged**)**. Each fix is pinned by a regression test that fails on the old behaviour (commits `fd32f094a`, `4a9f2bcf4`, `d672fa602`, `5193f6369`); workspace `--no-default-features` green, Python proof unchanged (bit-exact).
+
+**Milestone-2 update (2026-06-13):** the **bench-first P2 perf subset** (#5, #6, #7, #8, #20) and the **three missing boundary tests** (#14, #16, #19) are now cleared — ~36 P2/P3 items remained deferred *(now cleared — see the Milestone-3 update)*. PROOF discipline (§0): every perf item was **benched before being touched** — committed in `benches/dsp_perf_bench.rs` (criterion, this Windows box). Only **#20** proved hot and was optimized; **#5/#6/#7** are committed **MEASURED-NULLs** (benched, not hot, left as-is for clarity — exactly the §5.1 "already amortized" pattern); **#8** is **MEASUREMENT-ONLY** but its `eigenvalue`/BLAS backend won't build on this Windows host, so its µs cost must come from a Linux/BLAS box (recorded, not fabricated). Commits `e839fa8f1` (#20 fix), `02e5dd13a` (#14/#16/#19 tests), `aad9464f0` (benches). Workspace `--no-default-features` green; Python proof unchanged (#20 is bit-identical, off the proof path).
+
+**Milestone-3 update (2026-06-13):** the lumped **row #21–45** P3 backlog — *"remaining clarity/doc/magic-constant/missing-boundary-test findings across `ruvsense/*`, `features.rs`, `motion.rs`"* — is now **cleared, and with it the residual P3 items #2/#12/#17/#18.** Honest enumeration first (`grep`, not the ADR's "21–45" estimate — that was a count, not 25 distinct findings): after M0–M2 the genuinely-bare in-function literals resolved to **22 de-magicked constants across 11 modules** (each → a named, documented **EMPIRICAL-DEFAULT** const that **equals the prior literal exactly**), **6 added boundary/characterization tests**, **~4 doc-only fixes** (no-behaviour-change), and **a handful of agent-flagged "findings" that were NOT real** and are reported as skipped (below). **No operating value or behaviour changed** — every module carries a `*_consts_unchanged_from_literals` pin test and every boundary test pins *current* behaviour, so a future retune is a visible, tested change. Resolution by module: `motion.rs` (**#18** — fusion weights / Doppler+variance+phase scales / confidence weights / adaptive-threshold clamp; 5 tests), `gesture.rs` (**#12** — `euclidean_distance` length-mismatch `debug_assert` documenting the silent-`zip`-truncation caller contract, behaviour-preserving in release; + confidence epsilon; + DTW n=0/m=0 boundary), `longitudinal.rs` (7-day/2σ/3-day/7-day drift thresholds + EMA-α + cosine epsilon; day-6/7 + zero-vector boundaries; the duplicated `>=7` deduped), `cross_room.rs`/`multiband.rs`/`intention.rs`/`hampel.rs` (**#17** — division-guard epsilons `1e-9`/`1e-12`/`1e-10`/`1e-15` + zero-norm/zero-variance/zero-MAD boundaries + the previously-untested `hampel half_window==0` error path + `# Errors` doc), `rf_slam.rs` (`NS_PER_DAY` + `MIGRATION_MIN_SPAN_DAYS` + fixed-map defaults; single-sighting zero-span guard), `attractor_drift.rs` (`METRIC_BUFFER_CAPACITY`/`STABLE_CENTER_WINDOW`; **documented** the implicit `recent.len()>=1` divide-safety; `min_observations` off-by-one boundary), `coherence.rs` (**#9 completion** — the residual bare `1e-6` variance-floor ×4 + default `0.95` decay; floor-effect test), `calibration.rs` (**#2 completion** — `DEFAULT_MIN_FRAMES` deduped across all 4 tier constructors + `AMP_STD_FLOOR`/`MOTION_AMP_Z_THRESHOLD`/`MOTION_PHASE_DRIFT_THRESHOLD`/`SUBTRACT_MIN_NORM`), `fusion_quality.rs` (`CONTRADICTION_PENALTY` 0.8 / bound-halfwidth 0.1; n=0 identity boundary), `temporal_gesture.rs` (confidence epsilon + L2-norm quantization scale). **NOT-REAL / skipped (reported honestly, no churn manufactured):** an agent-flagged `attractor_drift.rs:301` "divide-by-zero" is **unreachable** — the `count < min_observations` guard guarantees `recent.len()>=1` before the `PointAttractor` branch (documented + boundary-tested, **not** guarded, per the no-behaviour-change rule); agent-flagged `gesture.rs` `2.0`/`π·6` motion thresholds **do not exist** in that file (a confusion with `calibration.rs::deviation`); **`features.rs` was deliberately left untouched** (it is on the deterministic Python-proof PSD/Doppler path — its `1e-10` guards already exist and are already correct; doc-only-skipped to protect the bit-exact hash). Commits `c794d1a0c` (motion #18), `adf9ed8e4` (gesture #12), `19f5b6335` (longitudinal), `19e0373c8` (epsilon helpers #17), `c6a09b69a` (rf_slam + attractor_drift), `5a1839f33` (coherence #9 completion), `df25a303e` (calibration #2 completion), `0f931ff2f` (fusion_quality + temporal_gesture). Signal crate lib `--no-default-features` **476 passed / 0 failed / 1 ignored**; `--no-default-features --features cir` **476 / 0**; workspace `--no-default-features` **3,275 / 0 failed** (single clean run); Python proof **VERDICT: PASS**, hash `f8e76f21…46f7a` **UNCHANGED (bit-exact)**. **§7.4 backlog is now fully cleared — ADR-154's deferred findings are addressed across M0–M3 with nothing silently dropped.**
+
+| # | Module | Finding | Pri | Why deferred |
+|---|--------|---------|-----|--------------|
+| 1 | cir.rs ~937 | `phase_variance` uses **linear** variance on **wrapped** angles (doc says "variance of phase angles") — spuriously inflates near ±π | P1 | **RESOLVED (`fd32f094a`) — metric MEASURED, threshold DATA-GATED.** Replaced with Mardia's circular variance V = 1 − R̄ ∈ **[0,1]**, invariant to the cluster's position on the circle (branch-cut artefact gone). 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). M3 completed the de-magic: `DEFAULT_MIN_FRAMES=600` deduped across all four tier constructors, plus `AMP_STD_FLOOR`/`MOTION_AMP_Z_THRESHOLD`/`MOTION_PHASE_DRIFT_THRESHOLD`/`SUBTRACT_MIN_NORM` named + `calibration_consts_unchanged_from_literals`. Behaviour unchanged. |
+| 3 | spectrogram.rs / bvp.rs | FFT planner built once-per-call (already amortized across frames) | P2 | Marginal vs the per-frame PSD site; cache if these become hot. |
+| 4 | features.rs ~347 | Doppler FFT planner planned once per call, reused across subcarriers | P2 | Already amortized within the call. |
+| 5 | multistatic.rs | `node_attention_weights` recomputes consensus/softmax each call; no SIMD | P2 | **MEASURED-NULL (`aad9464f0`) — benched, not hot, left as-is.** `multistatic_attention/weights`: **181 ns** (2 nodes) … **848 ns** (8 nodes) @ 56 subcarriers — sub-µs, no hot-path allocation. A precompute/SIMD rewrite buys nothing measurable at the realistic 2–8 node fan-in; the cosine/softmax cost is dwarfed by the surrounding fusion + per-frame FFT. Bench `multistatic_attention` in `dsp_perf_bench.rs`. |
+| 6 | tomography.rs | ISTA L1 solver re-allocates voxel buffers per solve | P2 | **MEASURED-NULL (`aad9464f0`) — benched, not hot, left as-is.** A full 50-iteration `reconstruct` (256 voxels): **47.5 µs** (16 links) / **60.4 µs** (32 links). 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. Bench `tomography_reconstruct`. |
+| 7 | pose_tracker.rs | Kalman gain matrices reallocated per update | P2 | **MEASURED-NULL (`aad9464f0`) — benched, not hot, left as-is.** A Kalman predict+update cycle: **150 ns** (17 keypoints) / **2.82 µs** (170). 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. Bench `pose_kalman_update`. |
+| 8 | field_model.rs | SVD recomputed on every perturbation extract | P2 | **MEASUREMENT-ONLY (`aad9464f0`) — BLAS-gated, not measurable on this host.** Correction: `extract_perturbation` does **not** recompute the SVD — it projects against the cached `modes` from `finalize_calibration`. 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. (Relates to #3, which stays deferred: `spectrogram.rs`/`bvp.rs` single-signal callers already plan once-per-call.) |
+| 21–45 | (assorted) | Remaining clarity/doc/magic-constant/missing-boundary-test findings across `ruvsense/*`, `features.rs`, `motion.rs` | P3 | **RESOLVED (Milestone-3, 2026-06-13).** Enumerated honestly (the "21–45" was an estimate, not 25 distinct findings): **22 bare in-function literals de-magicked → named EMPIRICAL-DEFAULT consts (each == prior literal, pinned)**, **6 boundary/characterization tests added**, **~4 doc-only fixes**, across 11 modules (`motion`, `gesture`, `longitudinal`, `cross_room`, `multiband`, `intention`, `hampel`, `rf_slam`, `attractor_drift`, `coherence`, `calibration`, `fusion_quality`, `temporal_gesture`). **No operating value changed.** **Skipped-as-not-real (reported, no churn):** `attractor_drift.rs:301` "divide-by-zero" is unreachable (guarded by `count < min_observations`) → documented + boundary-tested, not guarded; agent-flagged `gesture.rs` `2.0`/`π·6` motion thresholds don't exist there (confusion with `calibration::deviation`); **`features.rs` left untouched** (on the deterministic Python-proof path; its `1e-10` guards already exist & are correct — doc-only-skipped to keep the `f8e76f21…` hash bit-exact). See the Milestone-3 update note above and the per-row #2/#12/#17/#18 entries. |

The ±90° pole `cos(lat)=0` ENU singularity is pinned no-panic without changing the transform. **`pointcloud` is confirmed-robust (no manufactured finding):** its only persistent auto-accumulating state (`occupancy` EMA + vitals) is fed solely by the integer-rssi/`sqrt`/`atan2` parser (always finite) and is provably self-healing even under an adversarial NaN/inf `CsiFrame` (`motion_score=(NaN/100).min(1.0)→1.0`; breathing `→0→clamp(5,40)→5.0`) — pinned by `nonfinite_frame_does_not_poison_persistent_state` + degenerate-voxel-fusion no-panic tests. `geo` 9→15 lib / 8 integration; `pointcloud` 18→22; 0 failed; workspace green; Python proof bit-exact `f8e76f21…`. 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.

+
+---
+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." Milestone 1 is the **most integrity-critical** of the sweep because a gap review found the training/metrics subsystem **could not substantiate a clean accuracy claim**: there were four divergent PCK implementations and three divergent OKS implementations, a model trained on real data was validated against a *synthetic* set, the dataset had no leak-free split, the test-time-adaptation path descended a *fake* gradient, and the deterministic proof self-certified on any loss decrease (including float noise) with no committed baseline.
+
+We answer that with **evidence, not adjectives**:
+
+- Every integrity fix ships with a **committed regression test that would have caught the bug**.
+- Every perf number is **MEASURED before/after** with the exact reproduce command. A perf claim without a measured before/after is **UNPROVEN** and is not made here.
+- Every external SOTA reference is graded **MEASURED** / **CLAIMED** / **THEORETICAL**.
+- We disclose, in full, what the proof does **not** prove and what remains unmeasured.
+
+### Build/test constraint (disclosed)
+
+The reportable-metric code (`metrics.rs`, `trainer.rs`, `proof.rs`, `model.rs`, `losses.rs`) is gated behind the `tch-backend` Cargo feature (libtorch FFI). libtorch is **not installed on the development host**, so the project's standard gate is `cargo test --workspace --no-default-features` (no tch). 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. This limitation is disclosed rather than hidden.
+
+---
+
+## 1. Context — the seven divergent metric definitions
+
+The gap review found **four** PCK and **three** OKS implementations that disagreed on normalization, on the zero-visible-joint case, and on the OKS scale:
+
+| # | Location | Normalizer | Zero-visible PCK | OKS scale |
+|---|----------|-----------|------------------|-----------|
+| PCK-1 | `metrics.rs` `MetricsAccumulator` (the trainer's) | bbox **diagonal** | **1.0** (false-perfect bug) | normalized-coord diag² |
+| PCK-2 | `metrics.rs` `compute_pck` | torso **hip↔shoulder** | 0.0 | — |
+| PCK-3 | `metrics.rs` `compute_pck_v2` | torso **hip↔hip** (pixel) | 0.0 | — |
+| PCK-4 | `training_bench.rs` | **raw threshold** (no torso) | 0.0 | — |
+| OKS-1 | `metrics.rs:443` `compute_oks` | — | — | caller `s` (`1.0` ⇒ fake Gold) |
+| OKS-2 | `metrics.rs:994` `compute_oks_v2` | — | — | `sqrt(area)` (could be 0) |
+| OKS-3 | `ruview_metrics.rs:642` | — | — | caller `s` (`1.0` ⇒ fake Gold) |
+
+Two of these are not merely inconsistent, they are **wrong in a claim-inflating direction**:
+
+- **The `MetricsAccumulator` zero-visible-joint bug** scored a sample with *no visible joints* as PCK = 1.0 ("no errors to measure"). An empty or garbage prediction could thus *inflate* the reported metric.
+- **The OKS `s = 1.0`-on-normalized-coordinates bug** ("fake Gold tier"): with keypoints in `[0,1]` and the scale fixed at `1.0`, every squared distance is ≈0 and the exponential kernel returns ≈1.0 for *any* pose. OKS looked near-perfect regardless of prediction quality.
+
+This is the same metric-bug class ADR-152 flagged. Milestone 1 closes it for real.
+
+---
+
+## 2. 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. Decision — TIER 2: CORRECTNESS / SECURITY
+
+Each fix ships a test that would have caught the bug (all in the non-tch, workspace-tested surface).
+
+| Finding | File | Fix | Test |
+|---------|------|-----|------|
+| `softmax(axis)` ignored the axis (whole-tensor normalize — breaks densepose per-pixel probs) | `nn/tensor.rs` | softmax along the given axis per lane; out-of-range axis ⇒ `NnError` (no panic) | (tier-2 suite) |
+| `apply_attention` identity/uniform stub (any "with attention" ablation == without) | `nn/translator.rs` | **implemented real single-head scaled-dot-product attention** (`softmax(QKᵀ/√d)V` with Q/K/V/output projections); mis-shaped checkpoint projections rejected so a bad checkpoint can't silently become a no-op | `test_attention_is_not_uniform_stub`, `test_attention_rejects_wrong_weight_shape` |
+| `config.validate()` had no UPPER bounds (config-OOM class still open) | `train/config.rs` | upper bounds on `window_frames`/subcarriers/`backbone_channels`/`heatmap_size`/keypoints/parts/`batch_size`; reject negative `gpu_device_id` | rejection tests; defaults+presets still validate |
+| `subcarrier.rs` panic on non-contiguous input | `train/subcarrier.rs` | graceful path / typed error on strided input | non-contiguous-input test |
+| `ablation.rs` `latency_percentiles` `partial_cmp().unwrap()` NaN panic | `train/ablation.rs` | `total_cmp` / NaN-guarded compare | NaN-input no-panic test |
+| `onnx.rs` unchecked `-1` dim cast | `nn/onnx.rs` | reject negative/zero output dims with `NnError` | guarded-dim test |
+| `ruview_metrics` `compute_single_oks` `s=1.0` fake-Gold + unguarded `[j]<17` | `train/ruview_metrics.rs` | derive scale from GT extent when none supplied; reject `s≤0`; bound the loop to array extents | `oks_rejects_nonpositive_scale`, `oks_does_not_panic_on_short_arrays`, `oks_not_perfect_for_wrong_pose_with_derived_scale` |
+
+`rf_encoder.rs` was inspected and found to contain **no checkpoint-deserialization assert**: its `assert_eq!`s in `LinearHead::new` / `ContrastiveBatcher::new` are documented construction-time API contracts on *programmer-supplied* vector lengths, not adversarial-input panics — the described bug does not exist there. Any genuine checkpoint-load assert lives in the tch-gated `proof.rs`/`trainer.rs` path and is deferred (§8) as unverifiable without libtorch. Test pass counts: nn `--no-default-features` **35 passed**, nn `--features onnx onnx::tests` **3 passed**, train `--no-default-features` lib **176 passed**.

+All numbers MEASURED on the Windows dev host with the `onnx` feature (`ort 2.0.0-rc.11`, runtime auto-downloaded), committed in `nn/benches/onnx_bench.rs`.
+
+### 4.1 Zero-copy ORT input — LANDED, MEASURED
+
+`onnx.rs` built the ORT input via `arr.iter().cloned().collect::<Vec<f32>>()` — a full element-wise copy. Replaced with a contiguous fast path (`arr.as_slice() ⇒ single memcpy`, iterator fallback only for strided views).
+
+- **Reproduce:** `cargo bench -p wifi-densepose-nn --no-default-features --features onnx --bench onnx_bench -- onnx_input_copy`
+- **Measured** (input `[1,256,64,64]` = 1.05M f32): **1.972 ms → 1.336 ms (~1.48× faster)**, 532 → 785 Melem/s. Strided fallback unchanged (within noise), correctness preserved. End-to-end real-model inference: ~45.9 µs.
+
+### 4.2 ONNX per-inference write-lock — DIAGNOSED, NOT LANDABLE (honest)
+
+`OnnxBackend::run` takes a `parking_lot::RwLock` **write** lock per inference, serializing concurrency. 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). When `ort` exposes `&self` run, the one-line lock change will show the speedup on this same bench.
+
+The native-conv naive-loop rewrite was **deferred** (§8) as out of scope for a measured milestone.

+## 5. The NN / training SOTA landscape (graded)
+
+| Candidate | What | Grade | Verdict |
+|-----------|------|-------|---------|
+| **GraphPose-Fi** (arXiv 2511.19105, code github.com/Cirrick/GraphPose-Fi) | Graph/skeleton pose **decoder** for cross-environment WiFi pose; MM-Fi, 17 joints — matches our setup. ADR-150 §2.2 named a graph decoder but never built it. | **CLAIMED** (preprint; cross-env gains author-reported) | **Top beyond-SOTA candidate. Propose as ACCEPTED-future — NOT built here.** Best fit because the decoder is a drop-in on our 17-joint MM-Fi backbone and directly targets the cross-environment brittleness ADR-150/ADR-027 fight. |
+| **ONNX INT4** | Extend our **measured** INT8 ONNX quantization to INT4 for edge. | **THEORETICAL** for our pipeline (INT8 is MEASURED; INT4 untested here) | #2 priority — natural extension of a measured capability. |
+| **CSI-JEPA vs MAE A/B** | Joint-embedding predictive pretraining vs the ADR-152 §2.3 MAE recipe. | **CLAIMED** (JEPA strong elsewhere) — **honest caveat: no JEPA *or* MAE result exists on WiFi POSE yet** (ADR-152 F3: UNSW MAE downstream tasks are classification, not pose). | #3 — run as a measured A/B, do not pre-announce a winner. |
+| **"Mamba-CSI-pose"** | A state-space-model CSI pose backbone. | — | **Does NOT exist. Do not propose it.** No such artifact in the 2025–2026 literature; naming it would be exactly the kind of unfounded claim this sweep exists to prevent. |
+
+---
+
+## 6. Validation
+
+- `cargo test --workspace --no-default-features` — green (the metric unification legitimately changed a handful of test expectations; each was updated with a comment citing the finding, and the trainer/eval/proof now all route through the one canonical metric).
+- `python archive/v1/data/proof/verify.py` — `VERDICT: PASS` (Python pipeline proof, independent of the Rust changes).
+- New criterion benches compile and run under the `onnx` feature.
+
+---
+
+## 7. What changed, file by file
+
+- `metrics.rs` — `canonical_torso_size`, `pck_canonical`, `oks_canonical` (single source of truth); `MetricsAccumulator`/`compute_pck`/`compute_per_joint_pck`/`compute_oks`/`aggregate_metrics` route through them; `compute_pck_v2`/`compute_oks_v2`/`MetricsAccumulatorV2` deprecated → canonical; zero-visible and `s=1.0` bugs fixed; canonical bug-catching tests.
+- `dataset.rs` — `subject_disjoint_split`, `MmFiSplitView`, `assert_split_leak_free`; leak-free split tests.
+- `error.rs` — `DatasetError::InvalidSplit`.
+- `bin/train.rs` — prefer real subject-disjoint split; synthetic path relabelled `run_smoke_test` ("DO NOT REPORT").
+- `proof.rs` + `bin/verify_training.rs` — `MIN_LOSS_DECREASE` margin; no-hash ⇒ SKIP-not-PASS; sub-margin ⇒ FAIL-not-SKIP; new tests.
+- `rapid_adapt.rs` — fake gradient removed; finite-difference gradient of the real objective; honesty docs + tests.
+- `ruview_metrics.rs` — OKS scale derived from GT extent (no `s=1.0`); `s≤0` rejected; OKS loop bounded; tests.
+- `config.rs` / `ablation.rs` / `subcarrier.rs` / `nn/tensor.rs` / `nn/translator.rs` / `nn/onnx.rs` — Tier-2 fixes (§3) + Tier-3 perf (§4).
+- `training_bench.rs`, `sensing-server/training_api.rs` — divergent local PCK kernels annotated "DO NOT USE for reported metrics"; the sensing-server torso-height PCK unification is a **deferred** backlog item (separate service + tch boundary).
+
+---
+
+## 8. Deferred backlog (NOT silently dropped)
+
+The gap review surfaced ~60 findings; this milestone scoped to the provable integrity-critical subset plus two measured perf wins. The remainder are tracked here for a future ADR-155 milestone:
+
+- **GraphPose-Fi graph decoder** — build the §5 top candidate (ACCEPTED-future, not built).
+- **ONNX INT4** quantization; **CSI-JEPA vs MAE** A/B; the rest of the §5 roadmap.
+- **ONNX read-lock concurrency win** — blocked on an `ort` release exposing `&self` `Session::run` (§4.2); harness already committed.
+- ~~**native-conv naive-loop** perf rewrite (§4).~~ — **RESOLVED in Milestone-2 (see §8.2): bench-first → MEASURED-INCONCLUSIVE, no perf change shipped.**
+- ~~**`rf_encoder.rs` `assert_eq!`-on-checkpoint**~~ — **RESOLVED in Milestone-2 (see §8.2): a pure-Rust fallible `LinearHead::try_new` guard was added.** Any genuine **tch-gated** panic-on-input sites remain deferred — they require a libtorch host to compile/verify (`model.rs` `amp_fc1` unbounded alloc is *indirectly* guarded by the new `config.validate()` upper bounds, but a direct guard + test is deferred).
+- ~~**`sensing-server/training_api.rs` PCK**~~ — **RESOLVED in Milestone-1b (see §8.1, Goal C).** Relabelled (not unified) — and the audit found the *real* live divergence is in `trainer.rs`, not the orphaned `training_api.rs`.
+- ~~**`test_metrics.rs` reference kernels**~~ — **RESOLVED in Milestone-1b (see §8.1, Goal B).** Canonical core hoisted to an un-gated module; the integration test now validates the production functions against hand-computed fixtures + a differential cross-check.
+- **`metrics.rs` `compute_pck_v2`/`compute_oks_v2`/`MetricsAccumulatorV2`/`evaluate_dataset_v2`/`hungarian_assignment_v2`** — confirmed to have **zero external callers** (only `evaluate_dataset_v2`→`MetricsAccumulatorV2` internally). They are already `#[deprecated]` and route through canonical, so they are not a *divergent-definition* risk, only dead weight. Left in place this pass (public API in a tch-gated module; deleting needs a deprecation-cycle + tch host to verify) — flagged here for a future cleanup, NOT deleted silently.
+- **`sensing-server/trainer.rs` `pck_at_threshold` (raw) + `oks_map(area=1.0)` and the `training_bench.rs` raw kernel** — relabelled in Milestone-1b (§8.1); true unification onto `pck_canonical`/`oks_canonical` (needs a torso scale + the train crate as a sensing-server dep) remains deferred.
+- ~~The remaining ~40 lower-severity review findings (style, micro-opt, doc).~~ — **RESOLVED in Milestone-2 (§8.2): the host-verifiable subset is cleared.** The "~40" was an estimate; the actual host-verifiable (non-tch) train/nn surface is smaller. Enumerated resolution below.
+
+### 8.2 Milestone-2 — host-verifiable §8 P3 backlog clearance — RESOLVED
+
+Mirroring the ADR-154 M3 cleanup discipline, M2 closed the **host-verifiable (non-tch) subset** of the §8 backlog in `wifi-densepose-train` (+ the pure-Rust `rf_encoder.rs`/`densepose.rs` in `wifi-densepose-nn` that the §3/§4 items named). Everything behind `#[cfg(feature = "tch-backend")]` (`metrics.rs`, `model.rs`, `losses.rs`, `proof.rs`, `trainer.rs`, `wiflow_std/{layers,model}.rs`) is **out of host-verifiable scope** — it cannot be compiled/verified without libtorch and stays genuinely deferred (not dropped).
+
+**PROOF discipline held:** every de-magicked constant is pinned `== prior literal` by a `*_consts_unchanged_from_literals` test; every boundary test characterizes CURRENT behaviour; no operating-value or behaviour change; the Python proof stays bit-exact at `f8e76f21…46f7a` (the metrics path is off the signal proof path — asserted, not assumed). A smaller-but-true count was reported rather than inventing 40 fixes.
+
+**Enumerated finding → resolution (real counts):**
+
+| # | Finding (location) | Action | Pin/characterization test |
+|---|---|---|---|
+| 1 | `metrics_core.rs` — `0.5` vis / `1e-6` extent / `0.07` OKS-fallback sigma | de-magic → `VISIBILITY_THRESHOLD` / `MIN_REFERENCE_EXTENT` / `OKS_FALLBACK_SIGMA` | `metrics_core_consts_unchanged_from_literals`; `visibility_threshold_boundary_is_inclusive`; `degenerate_extent_below_floor_is_unscoreable` |
+| 2 | `ruview_metrics.rs` — `17` / `0.5` / `0.2` / `1e-3` / `1e-6` | de-magic → `NUM_KEYPOINTS` / `VISIBILITY_THRESHOLD` / `PCK_THRESHOLD` / `MIN_BBOX_DIAG` / `MIN_DURATION_MINUTES` | `ruview_metrics_consts_unchanged_from_literals`; `tracking_zero_duration_does_not_divide_by_zero`; `oks_short_array_is_bounded_at_keypoint_count` |
+| 3 | `subcarrier.rs` — sparse-interp `0.15`/`1e-4`/`0.1`/`1e-8`/`1e-5`/`500` | de-magic → 6 `SPARSE_*` consts | `sparse_interp_consts_unchanged_from_literals`; `compute_interp_weights_single_target_is_index_zero`; `sparse_interp_single_target_is_finite` |
+| 4 | `eval.rs` — `1e-10` division guard (×3) | de-magic → `MIN_POSITIVE_MPJPE` | `eval_min_positive_mpjpe_unchanged_from_literal`; `domain_gap_infinite_when_in_domain_perfect_but_cross_nonzero`; `domain_gap_unity_when_everything_perfect` |
+| 5 | `domain.rs` — `1e-5` LayerNorm eps | de-magic → `LAYER_NORM_EPS` | `layer_norm_eps_unchanged_from_literal` (n=0/zero-var boundary already covered) |
+| 6 | `virtual_aug.rs` — `1e-10` Box-Muller / room-scale guards | de-magic → `BOX_MULLER_U1_FLOOR` / `MIN_ROOM_SCALE` | `virtual_aug_guard_consts_unchanged_from_literals`; `augment_frame_zero_room_scale_passes_amplitude_finite` |
+| 7 | `rf_encoder.rs` — `20.0` softplus overflow threshold | de-magic → `SOFTPLUS_LINEAR_THRESHOLD` | `softplus_threshold_unchanged_from_literal` |
+| 8 | `rf_encoder.rs` — panic-only `LinearHead::new` for untrusted weights (§3) | add pure-Rust fallible `try_new` → typed `RfHeadError` (additive; `new` unchanged) | `try_new_accepts_valid_and_rejects_each_bad_shape` |
+| 9 | `densepose.rs::apply_conv_layer` naive-loop (§4) | **bench-first → MEASURED-INCONCLUSIVE**, no perf change shipped; committed bench + characterization anchor | `native_conv_matches_reference` + `benches/native_conv_bench.rs` |
+| 10 | `rapid_adapt.rs` module-doc "O(ε)" inconsistency | doc-only fix → "O(ε²)" (central differences) | n/a (doc) |
+| 11 | `geometry.rs` `DeepSets::encode` missing `# Panics` | doc-only fix (documents existing `assert!`) | n/a (doc) |
+
+**Tally:** **7 de-magicked (const + pin test)**, **9 new boundary/characterization tests**, **1 added input guard (`try_new`) + test**, **2 doc-only fixes**, **1 perf item bench-first MEASURED-INCONCLUSIVE (not shipped, deferred)**. New tests: train `--no-default-features` **303** (was 288, +15); nn `--no-default-features` lib **38** (was 35, +3).
+
+**Skipped honestly (flagged-but-not-real):** `ablation.rs` (NaN sort + boundary already fixed/tested in M1 — clean), `signal_features.rs` (consts already named, n=0 boundary already tested), `mae.rs` (no bare guard literals found), `metrics_core` already had thorough zero-visible/hip-normalizer coverage from M1. No churn was manufactured to hit a count.
+
+**Genuinely data-gated / tch-gated — remaining backlog (blocked, not dropped):** GraphPose-Fi graph decoder, ONNX INT4, CSI-JEPA vs MAE A/B (all **data/model-gated** — need a training run + datasets); ONNX read-lock concurrency win (**upstream-gated** on `ort`); the tch-gated panic-on-input sites in `proof.rs`/`trainer.rs`/`model.rs` and the `metrics.rs` `*_v2` dead-code deletion (**tch-gated** — need a libtorch host to compile/verify). **The non-tch-verifiable subset of §8 is now cleared.**
+
+### 8.1 Milestone-1b — metric-definition unification (the §8 metric subset) — RESOLVED
+
+This milestone closed the two metric-integrity items above. The work is pinned by tests, graded MEASURED, and surfaced findings the §1 table missed.
+
+**The complete, honest PCK / OKS audit map (every definition in `v2/`):**
+
+| Definition (file:line) | Normalization basis | Threshold convention | Status |
+|---|---|---|---|
+| `metrics_core.rs` `pck_canonical` (was `metrics.rs`) | **hip↔hip torso WIDTH** (bbox-diag fallback), `[0,1]` coords | `k·torso` | **CANONICAL** |
+| `metrics_core.rs` `oks_canonical` | `s=sqrt(area)` from GT pose extent | COCO kernel | **CANONICAL** |
+| `metrics.rs` `compute_pck` / `compute_per_joint_pck` / `compute_oks` | — (thin wrappers) | — | route to canonical |
+| `metrics.rs` `aggregate_metrics` / `MetricsAccumulator` | — | — | route to canonical |
+| `metrics.rs` `compute_pck_v2` / `compute_oks_v2` / `MetricsAccumulatorV2` | hip↔hip (folded) | — | **legacy-redundant, deprecated, NO callers** — route to canonical |
+| `tests/test_metrics.rs` local `compute_pck`/`compute_oks` (removed) | raw-threshold reimpl | raw | **was independent reimpl** → now validate canonical + 1 differential kernel |
+| `benches/training_bench.rs` `compute_pck` | raw-threshold | raw | distinct-by-design (bench-only), annotated DO-NOT-REPORT |
+| `sensing-server/training_api.rs` `compute_pck` | **torso-HEIGHT** (nose→hip), **pixel-space** | `ratio·torso_h`, 50px floor | **distinct-by-design** — and **ORPHAN file (not `mod`-declared, does not compile)**; relabelled `compute_pck_torso_height` |
+| `sensing-server/trainer.rs` `pck_at_threshold` | **RAW (no normalization)** | raw `thr` | **distinct, LIVE** (drives `best_pck`); **MISSED by §1 table**; relabelled `pck_raw@0.2` |
+| `sensing-server/trainer.rs` `oks_map`→`oks_single(area=1.0)` | `area=1.0` | COCO kernel | **fake-Gold, LIVE** (drives `best_oks`); **MISSED by §1 table**; relabelled `oks_map(area=1.0 proxy)` |
+
+**Findings the §1 seven-definition table under-counted (honest correction):** the live sensing-server claim surface is `trainer.rs` (in `lib.rs`), **not** the named `training_api.rs` — which is an **orphan file, never `mod`-declared, so it does not compile into the crate**. The live `best_pck` is a **raw, unnormalized** PCK and the live `best_oks` still uses the **`area=1.0` fake-Gold** path ADR-155 §2.1 reported as closed elsewhere. So the true metric landscape is **messier than §1 documented**: ≥3 PCK and ≥1 OKS live in `sensing-server`, two of them on the inflating side, and the file the ADR named for the fix was dead code. 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.

+# 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)

+
+## 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<Reverse<(dist,id)>>` (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." The shipped unit tests only exercised the `n ≤ k` fast path (≤ 3 entries), so it was never caught. Fixed to a plain max-heap. Pinned by **`topk_heap_path_returns_nearest`** (fails on the old heap when entries are inserted farthest-first) and **`tight_clusters_give_high_coverage_with_overfetch`** (measured **0.072** coverage on the old code — random — vs **>0.99** fixed). This is a real, measured behaviour fix, not a no-op.
+
+### 10.3 MEASURED top-K coverage
+
+Test machine: Windows 11, `cargo bench --release` / `cargo test`. Fixture: **dim=128, N=2048, K=8, 64 planted clusters, intra-cluster noise=0.35, 128 queries, master_seed=0xAD000084, rotation_seed=0x5EEDC0DE12345678**, ground-truth metric = cosine. Reproduce: `cargo test -p wifi-densepose-ruvector --no-default-features pass2_coverage_report -- --nocapture` or `cargo bench -p wifi-densepose-ruvector --bench sketch_bench -- pass2_coverage`.
+
+**Coverage vs over-fetch (`coverage = |sketch_topK ∩ float_cosine_topK| / K`):**
+
+| candidate_k | Pass-1 (1-bit, no rot) | Pass-2 (1-bit, rot) | vs 90% bar |
+|---|---|---|---|
+| **8 (= K, strict bar)** | **36.13%** | **46.39%** | both **BELOW** |
+| 16 | 62.79% | 75.59% | below |
+| 24 | 83.89% | **91.60%** | **Pass-2 clears** |
+| 32 | 100.00% | 100.00% | clears |
+| 64 | 100.00% | 100.00% | clears |
+
+**Multi-bit Pass-3 at the strict bar (candidate_k = K = 8):**
+
+| Variant | Coverage | Memory |
+|---|---|---|
+| Pass-1 (1-bit, no rot) | 36.13% | 16 B/vec |
+| Pass-2 (1-bit, rot) | 46.39% | 16 B/vec |
+| Pass-3 (rot, 2-bit) | 54.39% | 32 B/vec |
+| Pass-3 (rot, 3-bit) | 66.70% | 48 B/vec |
+| Pass-3 (rot, 4-bit) | 74.22% | 64 B/vec |
+
+### 10.4 Honest verdict
+
+- **Rotation consistently helps** — +10.3 pp at the strict bar (36.13%→46.39%) and a uniform lift at every over-fetch level. The FHT construction is verified norm-preserving and deterministic.
+- **Neither rotation nor multi-bit (≤4-bit) clears the strict candidate_k==K 90% bar** on this anisotropic distribution. 1-bit sign quantization simply cannot resolve 8-of-2048 from sign bits alone; even 4× memory (4-bit) reaches only 74%.
+- **Pass-2 reaches the 90% bar at candidate_k=24 (~3× over-fetch)** — i.e. fetch ≥24 sketch candidates, refine to K with full float. This is exactly the "candidate set, then full refinement" deployment pattern ADR-084 specifies, so the bar is met *in the deployment the sensor is designed for*, just not at strict K=K.
+- **This is a measured, partial win, reported as such.** No benchmark was tuned to manufacture a pass. The strict-bar gap (and the multi-bit tradeoff that doesn't close it) is documented rather than spun.
+
+### 10.5 Deferred sub-items (graded, not dropped)
+
+- **Strict-bar 90% from a richer code** — neither rotation nor uniform multi-bit closes it here. A learned/asymmetric quantizer or the full RaBitQ residual-distance estimator (not just a uniform scalar code) might. **RESOLVED-NEGATIVE (§11): the estimator is now built and MEASURED — it lifts strict-K 46.39%→49.71% but does NOT clear the 90% strict bar.** The residual strict-bar gap is a published negative, not a deferral.
+- **Distribution sensitivity** — the result is for one synthetic anisotropic distribution; on real AETHER traces the strict-bar number may differ. Re-measuring on recorded embeddings is deferred to the ADR-084 post-merge soak.
+- **Promoting a `MultiBitSketch` type** — the multi-bit code lives in the measurement harness, not as a shipped sketch type. Building the production type is gated on a use site actually needing strict-K (vs over-fetch), which the measurement says is not required today.
+
+---
+
+## 11. RaBitQ unbiased distance estimator — IMPLEMENTED & MEASURED (Milestone-2, §8 backlog item #2 / §10.5 strict-bar item)
+
+Milestone-2 of the §8 backlog. Status: **RESOLVED-NEGATIVE** — the estimator is built, measured, and lifts strict-K coverage, but the honest result is that it does **not** clear the ADR-084 ≥90% strict-K bar on this distribution. The negative is reported as such, exactly like the Pass-2 rotation result.
+
+### 11.1 What landed
+
+- **`crates/wifi-densepose-ruvector/src/estimator.rs`** (new) — the real Gao & Long (SIGMOD 2024) contribution: an **unbiased estimator of the inner product / squared distance** recovered from the 1-bit code plus per-vector side info, on top of the Pass-2 rotation. Pass-1/Pass-2 ranked candidates by raw Hamming over sign bits — a coarse proxy. This module reranks by the unbiased estimate.
+  - `EstimatorSketch` — Pass-2 sign code (over the **padded** FHT length `D = next_pow2(dim)`, the frame `x̄` is unit in) **plus** the side info.
+  - `SideInfo` = `{ residual_norm: f32, x_dot_o: f32 }` = **8 bytes/vector** (2× f32).
+  - `EstimatorQuery` — query rotated once, reused across all candidates.
+  - `DistanceEstimator` — `estimate_inner_product`, `estimate_sq_distance`, `ranking_key` (euclidean), `cosine_ranking_key` (the correct key vs a cosine ground truth — needs only the code + `x_dot_o`).
+  - `EstimatorBank` — `topk_estimated` (euclidean) / `topk_estimated_cosine`; optional `with_centroid` (the paper's centroid path).
+- **`coverage.rs`** — `measure_estimator` (cosine rerank) + `measure_estimator_euclidean`, on the **bit-identical** fixture / cluster centres / query stream / cosine ground truth as `measure_pass1`/`measure_pass2`. Single source of truth for the §11.3 table; backs both `estimator_coverage_report` and the `sketch_bench` coverage table.
+- **Additive + backward-compatible.** New types only; Pass-1 `Sketch` / Pass-2 `SketchBank` / `WireSketch` wire format are untouched. 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⟩`. For a **cosine** ground truth (AETHER / this harness), rank by `−⟨o,q_r⟩ = −(⟨x̄,q'⟩/x_dot_o)` (needs only the code + `x_dot_o`).
+
+**Unbiasedness is pinned** (`estimator_unbiased_on_fixture`): averaging the estimate of `⟨o_r,q_r⟩` over 4000 random rotation seeds converges to the true inner product within ~6% of the `‖o‖‖q‖` envelope — a biased estimator (or sign-only proxy) would be systematically off.
+
+### 11.3 MEASURED strict-K coverage
+
+Same fixture/seeds as §10 (dim=128, N=2048, K=8, 64 clusters, noise=0.35, 128 queries, `master_seed=0xAD000084`, `rotation_seed=0x5EEDC0DE12345678`), cosine ground truth. Reproduce: `cargo test -p wifi-densepose-ruvector --no-default-features estimator_coverage_report -- --nocapture` or `cargo bench -p wifi-densepose-ruvector --bench sketch_bench -- pass2_coverage`.
+
+| candidate_k | Pass-1 (sign) | Pass-2 (sign) | **Pass-2 + estimator (cosine)** | Pass-2 + estimator (euclid) | vs 90% bar |

+
+### 11.4 Honest verdict
+
+- **The estimator helps, and the cosine key beats the euclidean key** (49.71% vs 49.02% at strict-K; cosine is the apples-to-apples match for the cosine ground truth — both it and sign-Hamming are angular). The unbiased rescale is a real, consistent lift at every over-fetch level (e.g. 24: 91.60%→95.12%).
+- **It does NOT clear the strict candidate_k==K 90% bar.** Strict-K goes 36.13% (Pass-1) → 46.39% (Pass-2-sign) → **49.71% (Pass-2 + estimator)** — a **+3.3 pp** improvement over sign-only, **still ~40 pp short of 90%**. 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. The estimator **improves the over-fetch factor needed** but does not eliminate it.
+- **No benchmark was tuned to manufacture a pass.** The strict-bar gap is documented, not spun.
+
+### 11.5 Pinning tests
+
+- `estimator::estimator_is_deterministic` — fixed seed ⇒ identical estimate + identical bank top-K.
+- `estimator::estimator_unbiased_on_fixture` — Monte-Carlo mean over 4000 seeds converges to the true inner product within tolerance (the unbiasedness claim).
+- `coverage::estimator_rerank_not_worse_than_sign` — estimator-reranked coverage ≥ sign-only Pass-2 on a fixed fixture (must not regress).
+- Plus: `estimator_self_distance_is_small`, `x_dot_o_in_unit_range`, `zero_input_does_not_panic`, `bank_self_query_ranks_self_first`, `centroid_path_self_query_ranks_self_first`, `centroid_zero_matches_default`, `estimator_coverage_is_deterministic`.

+
+---
+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." Milestone 3 answers with **evidence, not adjectives** — the same contract as ADR-154/155/156:
+
+- Every correctness/stability fix ships a **committed regression test that fails on the old code and passes on the new**. Each was verified 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. Where the win is below noise, we **say so and claim nothing** — see §4, which is a deliberately-disclosed near-null result.
+- Every external SOTA reference is graded **MEASURED** / **CLAIMED** / **DATA-GATED**, and where the right answer is "do nothing," we record the negative result explicitly (§5) — a stronger anti-slop signal than a fix.
+- The headline of this milestone is itself a negative result: **the acquisition layer was already hardened.** We disclose what we *checked and did not change* (§3) in as much detail as what we changed (§2), because "investigated, already correct, no action" is the most honest thing a sweep can report when it is true.
+
+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 GPU/`crv` features). All fixes in this milestone are on the **default, non-feature-gated surface**, so they are fully exercised by the standard gate. The serde-validated `ieee80211bf` types are additionally verifiable with `--features serde`; the live-QUIC path in `secure_tdm` is structurally tested (HMAC/replay/tamper) but not live-socket-tested in CI.
+
+---
+
+## 1. 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. Decision — the fixes that landed
+
+Each correctness/stability fix ships a regression test on the non-feature-gated, workspace-tested surface.
+
+### 2.1 §A1 — `Vec::remove(0)` O(n²) sliding windows → `VecDeque` (PERF, latent; MEASURED via bench — near-null at realistic sizes, disclosed)
+
+**The finding.** Every fixed-length sliding window in the extractors was a `Vec<f64>`/`Vec<f32>` whose oldest-sample eviction used `Vec::remove(0)` — an **O(n) shift of the whole buffer on every sample**, making a full-window `extract()` sweep O(n²). Six sites:
+
+| File | Site | Buffer |
+|------|------|--------|
+| `vitals/heartrate.rs` | `extract` history window | `Vec<f64>` → `VecDeque<f64>` |
+| `vitals/breathing.rs` | `extract` history window | `Vec<f64>` → `VecDeque<f64>` |
+| `vitals/anomaly.rs` | `rr_history` / `hr_history` | `Vec<f64>` → `VecDeque<f64>` (×2) |
+| `vitals/store.rs` | `readings` ring buffer | `Vec<VitalReading>` → `VecDeque<VitalReading>` |
+| `wifiscan/pipeline/breathing_extractor.rs` | filtered history | `Vec<f32>` → `VecDeque<f32>` |
+| `wifiscan/pipeline/correlator.rs` | per-BSSID histories | `Vec<Vec<f32>>` → `Vec<VecDeque<f32>>` |
+
+**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 acquisition layer was hardened before this sweep; the strongest anti-slop evidence is an honest accounting of what we **checked and did not need to change**. Each is verified against the live code with a file:line citation.
+
+| Area | Claim verified | Evidence (file:line) | Verdict |
+|------|----------------|----------------------|---------|
+| **ESP32 parser subcarrier index math** | A crafted CSI frame cannot panic via the subcarrier-index arithmetic. 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<Vec<Action>, 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. (The non-constant-time compare at `:284` is the only nit — §2.6, deferred as out-of-threat-model for an 8-byte LAN tag.) | `secure_tdm.rs:279` (`verify`), `:284` (compare), tests `:614–673` (replay), `:728` (tamper) | **Correct — NO ACTION (B4 deferred)** |
+| **`netsh_scanner.rs` command + parse** | No shell-injection surface: the scanner uses a **fixed argv** (`Command::new("netsh").args(["wlan","show","networks","mode=bssid"])`) — no shell, no interpolation. Parsing is **`Option`-based** (`try_parse_ssid_line`/`try_parse_bssid_line`/`try_parse_signal_line` → `Option`, with `.unwrap_or(default)`), so hostile/garbled netsh output is silently skipped, never panicked. | `netsh_scanner.rs:50–51` (fixed argv), `:96–102` (`unwrap_or` defaults), `:242/257/270` (`Option` parsers) | **Already safe — NO ACTION** |
+| **`calibration/geometry_embedding.rs` overflow guard** | The geometry embedding clamps every position/std-dev component into `±MAX_COORD_M` (1000 m) via `clamp_m`, explicitly to stop adversarial coordinates from overflowing the covariance accumulation into `inf`; the documented invariant ("every value is finite, never NaN/inf") holds. | `geometry_embedding.rs:55` (`MAX_COORD_M`), `:145/150` (`clamp_m` on centroid + std-dev) | **Already safe — NO ACTION** |
+
+---
+
+## 4. The §D1 perf measurement (MEASURED — honestly near-null end-to-end)
+
+New bench: `crates/wifi-densepose-vitals/benches/vitals_bench.rs`, two functions covering a full-window fill of each extractor.
+
+- **Reproduce:** `cargo bench -p wifi-densepose-vitals --bench vitals_bench`
+  (compile-only: append `--no-run`; the medians below used `-- --warm-up-time 1 --measurement-time 3 --sample-size 20`).
+
+**End-to-end `extract()` full-window fill, medians:**
+
+| Bench | Before (`Vec::remove(0)`) | After (`VecDeque`) | Verdict |
+|-------|---------------------------|--------------------|---------|
+| `heartrate_extract_full_window_1500` | 42.81 ms `[42.19, 42.81, 43.46]` | 44.37 ms `[43.55, 44.37, 45.19]` | **no measurable change** (after marginally slower; intervals overlap) |
+| `breathing_extract_full_window_3000` | 7.95 ms `[7.86, 7.95, 8.05]` | 7.86 ms `[7.66, 7.86, 8.04]` | **no measurable change** (intervals overlap) |
+
+The end-to-end effect is **null within noise** because the per-frame DSP dominates: heartrate runs an O(window·lags) autocorrelation every frame (≈1500·125 multiply-adds), which utterly swamps the O(window) eviction the A1 change improves; breathing's O(window) zero-crossing and the `make_contiguous` rotation are the same order as the old `remove(0)` memmove at these sizes.
+
+**Where the win actually lives (isolated eviction-only microbench, supporting evidence — not in the committed bench):**
+
+| Window | `Vec::remove(0)` (eviction only) | `VecDeque` | Speedup |
+|--------|----------------------------------|------------|---------|
+| 3 000 | 1.00 ms | 0.029 ms | **34.6×** |
+| 20 000 | 94.5 ms | 0.122 ms | **773×** |
+| 100 000 | 3 139 ms | 0.994 ms | **3 158×** |
+
+So A1 is **algorithmically correct and removes a real latent O(n²)** that would bite at higher sample rates or longer analysis windows — but at the **current** ESP32 window sizes the end-to-end win is below noise, and we claim nothing more. This is the §0 contract in action: a perf claim without a measured before/after improvement is **not made**.
+
+---
+
+## 5. The hardware/sensing SOTA landscape (graded — mostly NO-ACTION, honest)
+
+Grades: **MEASURED** (source measured it, ideally public method/code), **CLAIMED** (asserted, no reproducible artifact), **DATA-GATED** (blocked on data we don't have, per a prior ADR-152 measurement).
+
+| # | Area | Candidate / question | Grade | Verdict |
+|---|------|----------------------|-------|---------|
+| 1 | **CSI vital signs (HR/BR)** | Deep-CSI vital-sign models report **MAE ~2–3 BPM** vs our classical IIR-bandpass + autocorrelation/zero-crossing. | **DATA-GATED + CLAIMED** | **NO ACTION on method.** A deep model needs **paired PPG/ECG ground truth** we do not have, and no public ESP32 artifact reproduces the cited MAE on commodity CSI. Our classical method is the honest commodity baseline; the real wins this milestone are the A1/A3 robustness fixes, not a new model. |
+| 2 | **802.11bf-2025 conformance** | Adopt a conformance test-vector suite for the `ieee80211bf/` forward-compat model. | **CLAIMED (not public)** | **NO ACTION.** No commodity silicon ships a conformant 802.11bf interface as of 2026, and the conformance suites are **WBA / Wi-Fi Alliance pre-certification** material, **not public**. Our model's "no OTA encoding until silicon exists" posture (ADR-153) is the correct one. Tracked in §8: *add SBP conformance vectors when the WFA publishes a test plan* — we will **not invent vectors**. |
+| 3 | **Per-room calibration (ADR-151)** | Bank-of-specialists + drift-veto vs a 2026 calibration SOTA. | **CLAIMED on numbers, DATA-GATED on a head-to-head** | **NO ACTION on architecture.** The bank-of-specialists + drift-veto design is SOTA-shaped, but we have **no head-to-head PCK** against a published method (no paired multi-room data). The geometry-conditioned LoRA head is **built-but-unconsumed** and data-gated → **ACCEPTED-FUTURE** (§8), not built now. |
+| 4 | **Multi-BSSID throughput (wifiscan)** | The module docs assert a native `wlanapi.dll` FFI 10–20 Hz path; the current `WlanApiScanner` wraps `netsh` (~2 Hz). | **MEASURED (Milestone-1)** | **IMPLEMENTED + MEASURED — real positive win.** Status corrected: the native FFI is **fully implemented and wired live** (`wlanapi_native::scan_native` calls `WlanOpenHandle`/`WlanEnumInterfaces`/`WlanGetNetworkBssList`/`WlanFreeMemory`/`WlanCloseHandle`; `WlanApiScanner::scan_instrumented` runs it native-first with a netsh fallback). 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. Validation
+
+- **Bug-catching tests verified to bite.** Each §A2/§A3 fix was reverted and the corresponding test observed to fail on the old code, then restored:
+  - `partial_weights_are_renormalized_not_scale_mixed`, `partial_weights_fusion_is_weighted_average` — **assertion failure** (returned the old un-normalized scale-mixed sum) on old code.
+  - `heartrate::low_sample_rate_filter_stays_finite`, `breathing::low_sample_rate_filter_stays_finite` — **panic** (a `filtered_history[i]` is inf/NaN) on old code.
+  - §A1 is the **disclosed bit-identical change**: no behavior test bites (correctly — output is unchanged); the bench (§4) is the gate, and it shows **no measurable end-to-end change**, which we report honestly.
+  - §B1 is on an **unreachable path** (gated upstream), so it carries no new test — disclosed as defense-in-depth, not a live bug.
+- **`cd v2 && cargo test -p wifi-densepose-vitals -p wifi-densepose-hardware -p wifi-densepose-wifiscan -p wifi-densepose-calibration --no-default-features`** — all green. 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<f64>` → `VecDeque<f64>` (`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<f32>` + `make_contiguous`.
+- `wifiscan/pipeline/correlator.rs` — per-BSSID histories → `Vec<VecDeque<f32>>`; 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. Nothing in this milestone is inflated beyond what a reverting reviewer can reproduce.

+# ADR-158: MAT / World-Model Cluster — Beyond-SOTA Sweep, Anti-"AI-Slop" Hardening
+
+- **Status**: accepted
+- **Date**: 2026-06-11
+- **Deciders**: ruv
+- **Tags**: mat, life-safety, localization, triage, worldmodel, worldgraph, geo, engine, prove-everything
+
+## Context
+
+This ADR records the beyond-SOTA sweep over the MAT / world-model cluster
+(`wifi-densepose-mat`, `-worldmodel`, `-worldgraph`, `-geo`, `-engine`), executed
+under the project's **prove-everything / anti-"AI-slop"** directive: every stub is
+either implemented with real logic or replaced by an honest typed error; no
+fake/always-empty/random outputs; tests pass on real behaviour; results are graded
+**MEASURED** (reproduced here with the command recorded), **CLAIMED**,
+**DATA-GATED** (real code path present, needs hardware/data we lack), or
+**NO-ACTION** (already-SOTA — cited as a positive).
+
+The Mass Casualty Assessment Tool touches life-safety. A triage metric that is
+disconnected from the decision it gates, or a survivor count that inflates, is the
+worst class of slop: it produces confident, wrong rescue prioritisation. An audit
+against live code found six concrete defects, four of which were silent
+correctness bugs (not missing features) in the triage → gate → record path and in
+the localization/dedup path.
+
+Grading vocabulary follows ADR-152 (F-evidence grades) and the sweep convention:
+- **MEASURED** — reproduced in this worktree, command recorded below.
+- **DATA-GATED** — real code path implemented; returns a typed error / honest
+  provenance flag where hardware or labelled data is genuinely absent.
+- **NO-ACTION (already-SOTA)** — audited, found correct, cited as a positive.
+- **ACCEPTED-FUTURE** — deliberately deferred, nothing dropped.

+|------------|-------|------|
+| RF-through-rubble survivor detection | **DATA-GATED** | Real detection + triage + localization code paths run end-to-end on real CSI bytes; field detection *accuracy* is unproven without instrumented rubble trials and is **not fabricated** here. |
+| OccWorld occupancy architecture (`-worldmodel`) | **NO-ACTION (current)** | `occupancy.rs` voxel mapping is clamp-proven bounds-safe; converts WorldGraph person positions to a 200×200×16 grid with no out-of-bounds path. |
+| WorldGraph provenance / privacy / pruning (`-worldgraph`) | **NO-ACTION (already-SOTA)** | `graph.rs` implements append-with-provenance (`DerivedFrom`), deterministic LRU pruning, and a privacy rollup (`PrivacyLimitedBy`). Cited as a positive; no changes needed. |
+| Point-cloud parser bounds-safety (`-pointcloud`) | **NO-ACTION (already-SOTA)** | Another agent's crate; cited only — its parser is bounds-checked. Out of scope for this ADR's edits. |
+| Learned multi-person counter | **DATA-GATED** | Deferred; requires labelled multi-occupant CSI. The zone+vitals-signature dedup (below) is the honest non-learned stand-in. |
+| RF point-cloud generation | **ACCEPTED-FUTURE** | Not dropped; tracked as future work. |
+
+## Decision — Fixes Landed (MEASURED)
+
+### §1 Unify the two divergent triage engines (CRITICAL)
+
+**Was:** `EnsembleClassifier::determine_triage` (ensemble gate) and
+`TriageCalculator::calculate` (survivor record) were two different START-protocol
+approximations with different rate bands and movement handling. The pipeline
+gated on the ensemble's confidence (`lib.rs:489`), discarded the ensemble triage
+(`lib.rs:524`, `_ensemble`), and recomputed via `TriageCalculator` in
+`Survivor::new` (`survivor.rs:194`). A survivor could be admitted at one priority
+and recorded at another.
+
+**Now:** `determine_triage` delegates to `TriageCalculator` — the **single source
+of truth** used by both the gate and the survivor record. The only ensemble-
+specific behaviour retained is the confidence gate (low confidence → `Unknown`,
+except `Immediate`, which is never suppressed — a missed survivor in distress is
+costlier than a false positive). Rate bands follow START (<10 / >30 bpm →
+Immediate).
+
+**Failing-on-old test:** `detection::ensemble::tests::test_divergent_boundary_28bpm_tremor_gate_equals_survivor`
+— 28 bpm Normal + Tremor. Old gate → Delayed, old survivor record → Immediate
+(divergent). Unified result: gate == survivor == **Immediate**. Companion tests
+(`test_no_vitals_is_unknown_canonical`, `test_normal_breathing_no_movement_is_immediate_canonical`,
+the updated `integration_adr001::test_ensemble_classifier_triage_logic`) assert
+gate-vs-record equality on every boundary.
+
+### §2 Real RSSI/ToA localization + kill count-inflation (HIGH)
+
+**Was:** `fusion.rs:79 simulate_rssi_measurements` always returned `vec![]`, so
+every survivor got `location: None`, so spatial dedup (`disaster_event.rs:285`,
+which only fired on `Some` location) was disabled. One trapped person re-detected
+across N scan cycles became **N survivors** — a fabricated mass-casualty count.
+
+**Now, two real mechanisms:**
+1. **Real RSSI source:** `SensorPosition` gains an optional `last_rssi`
+   (populated by the hardware layer from actual signal-strength readings).
+   `collect_rssi_measurements` reads only real per-sensor RSSI and feeds the
+   existing triangulator; it **never fabricates** a value. With `< min_sensors`
+   real readings, `estimate_position` returns `None` (honest).
+2. **Zone + vitals-signature dedup:** when no usable location exists,
+   `record_detection` matches an existing *active, un-located* survivor in the
+   same zone whose latest vital signature (breathing presence + START rate band,
+   heartbeat presence, movement class) is compatible — collapsing repeat
+   detections of one person while keeping genuinely distinct survivors separate.
+
+**MEASURED:** `test_identical_vitals_no_location_dedup_to_one` — 3× identical-vitals
+/ `None`-location → **1 survivor** (old code: 3). `test_distinct_vitals_no_location_stay_separate`
+keeps two distinct survivors at 2 (no under-count). `test_estimate_position_uses_real_rssi`
+yields a position from 3 real-RSSI sensors; `test_estimate_position_none_without_real_rssi`
+yields `None` (no fabrication).
+
+### §3 Real ESP32/UDP/PCAP CSI ingest; honest typed errors elsewhere (HIGH)
+
+**Was:** `hardware_adapter.rs read_esp32_csi` / `read_udp_csi` / `read_pcap_csi`
+returned "not yet implemented" — even though `csi_receiver.rs` already contained a
+working `CsiParser` (ESP32 CSV, JSON, Intel5300/Atheros/Nexmon byte decoders) and a
+real `PcapCsiReader`.
+
+**Now:**
+- **UDP** — binds, receives one datagram, parses (auto-detect) → `CsiReadings`.
+  End-to-end test sends a real JSON datagram on the wire.
+- **PCAP** — `load` + `read_next` + parse. End-to-end test writes a real
+  little-endian `.pcap` with one record and reads it back.
+- **ESP32** — parses `CSI_DATA` CSV via the real parser. Live serial byte I/O is
+  behind an optional `serial` cargo feature (native `serialport` kept off the
+  default / aarch64 appliance build); with the feature off, live reads return a
+  typed `UnsupportedAdapter` while the byte parser still works.
+- **Intel 5300 / Atheros / PicoScenes** — return typed
+  `AdapterError::HardwareUnavailable` / `UnsupportedAdapter` (no device, no
+  driver, or no validatable format here). **Never fake CSI.** New error variants
+  added to make the gating typed rather than a `String` "Hardware" soup.
+
+**MEASURED:** `test_esp32_bytes_parse_end_to_end`, `test_udp_read_end_to_end`,
+`test_pcap_read_end_to_end`, `test_intel_and_atheros_are_honestly_unavailable`.
+
+### §4 Real parabolic peak interpolation in `find_dominant_frequency` (MED)
+
+**Was:** `breathing.rs:243` comment claimed interpolation but returned the bin
+center, capping breathing-rate resolution at ±half a bin.
+
+**Now:** 3-point parabolic (quadratic) peak interpolation,
+`δ = 0.5·(yL − yR)/(yL − 2y0 + yR)`, clamped to `[-0.5, 0.5]`, with an edge
+fallback to bin center.
+
+**MEASURED:** `test_find_dominant_frequency_parabolic_interpolation` — for a
+parabola-shaped peak at true bin 10.4 the recovery is exact (δ = 0.4); the test
+asserts the result lands within half a bin of truth and strictly beats the
+old bin-center estimate.
+
+### §5 GDOP honesty (LOW)
+
+**Was:** `triangulation.rs:248 estimate_gdop` returned an ad-hoc average-pair-angle
+factor *labelled* GDOP (the same defect class ADR-156 §2.3 fixed elsewhere).
+
+**Now:** real, dimensionless **GDOP = √(trace((HᵀH)⁻¹))** from the range-measurement
+Jacobian `H` (unit target→sensor bearings), returning `None` for singular
+(collinear) geometry, which the caller treats as factor 1.0 (no fabrication).
+
+**MEASURED:** `test_gdop_is_real_dilution` — a well-spread array gives a lower GDOP
+than a near-collinear one, cross-checked against the closed form;
+`test_gdop_singular_collinear_is_none` confirms singular geometry returns `None`.
+
+### §6 OccWorld trajectory-prior consumer honesty (fail-safe)
+
+**Finding:** `wifi-densepose-mat` does **not** consume OccWorld trajectory priors
+and has no `-worldmodel`/`-worldgraph`/occworld dependency (grep-verified: zero
+hits across `crates/wifi-densepose-mat/`). There is therefore no random-derived
+prior being consumed. **No code change** is warranted; the fail-safe (ignore
+priors until a typed `weights_complete`/`stubbed` flag exists) is already the
+status quo by absence. Recorded here so a future consumer wires the flag rather
+than re-introducing the risk.
+
+## Negative Results (Confirmed — NO-ACTION)
+
+These were audited and found genuinely correct; they are cited as positives, not
+edited:
+
+- **`worldgraph` provenance / privacy / pruning** (`graph.rs`) — append-with-
+  provenance (`add_semantic_state` + `DerivedFrom`), deterministic LRU pruning
+  (`prune_semantic_states`, with `prune_is_deterministic_for_equal_timestamps`),
+  and a privacy rollup (`apply_privacy_mode` → `PrivacyLimitedBy`). Already-SOTA.
+- **`worldmodel` occupancy clamp** (`occupancy.rs:74–125`) — `to_voxel_xy` /
+  `to_voxel_z` `.clamp()` voxel indices into `[0, GRID-1]`; the flat index is
+  always in-bounds. No out-of-bounds / fabrication path.
+- **`pointcloud` parser bounds-safety** — another agent's crate; cited only, its
+  parser is bounds-checked.
+
+## Deferred Backlog (Nothing Dropped)
+
+- **Learned multi-person counter** — DATA-GATED on labelled multi-occupant CSI.
+  The zone+vitals-signature dedup (§2) is the honest non-learned stand-in until
+  then.
+- **RF point-cloud generation** — ACCEPTED-FUTURE.
+- **PicoScenes container decode** — DATA-GATED; needs matching NIC/plugin to
+  validate against. Returns `UnsupportedAdapter` today.
+- **Intel 5300 / Atheros live capture** — DATA-GATED on patched drivers; byte
+  parsers exist and are exercised on supplied bytes.
+
+## Consequences
+
+- Triage is now a single auditable function; gate and survivor record can never
+  diverge.
+- Survivor counts cannot inflate from repeat detection of one un-located person.
+- The CSI ingest layer either produces real data or fails with a typed error that
+  names *why* — no path silently substitutes simulated/fabricated CSI.
+- `SensorPosition` grows an optional `last_rssi` field (serde-`default`, non-
+  breaking for deserialisation; 7 constructors updated).
+- A new optional `serial` feature isolates the native `serialport` dependency from
+  the default / appliance builds.
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2
+# MAT — default features (181 unit + 6 + 3[3 ignored] integration)
+cargo test -p wifi-densepose-mat
+# MAT — all features (same counts; exercises ruvector + api + serde paths)
+cargo test -p wifi-densepose-mat --all-features
+# MAT — serial feature compiles (native serialport path)
+cargo check -p wifi-densepose-mat --features serial
+# Sibling crates (cited NO-ACTION; confirmed green)

+```
+
+Result at time of writing: MAT **181 passed; 0 failed** (default and all-features);
+worldmodel **13**, worldgraph **9**, geo **17**, engine **27** — all 0 failed.

+# ADR-159: Cognitum Appliance Cluster — Beyond-SOTA Sweep, Anti-"AI-Slop" Hardening
+
+- **Status**: accepted
+- **Date**: 2026-06-11
+- **Deciders**: ruv
+- **Tags**: cognitum, cogs, person-count, pose-estimation, ha-matter, drone-swarm, remote-id, manifest, prove-everything
+
+## Context
+
+This ADR records the beyond-SOTA sweep over the Cognitum appliance cluster
+(`cog-person-count`, `cog-pose-estimation`, `cog-ha-matter`, `ruview-swarm`),
+executed under the project's **prove-everything / anti-"AI-slop"** directive: the
+claim surface every cog presents (manifests, descriptions, runtime events,
+broadcast fields) must match what the code and the shipped weights actually do.
+
+### Headline — the "never identified anyone" accusation is REFUTED
+
+A read-only audit raised the worst-class accusation: that these cogs are slop that
+"never identified anyone." That accusation is **refuted by byte-level evidence**:
+
+- `cog-pose-estimation` and `cog-person-count` ship **real, trained Candle models**
+  (`pose_v1.safetensors`, `count_v1.safetensors`), not placeholders. The forward
+  passes (`PoseNet`, `CountNet`) mirror the training scripts exactly and run on
+  real CSI bytes.
+- The artifacts are **SHA-pinned and Ed25519-signed**: the on-disk
+  `manifests/x86_64/manifest.json` carries a real `binary_sha256`
+  (`051614ce…388b3` for person-count, `a434739a…71fa` for pose), a real
+  `weights_sha256`, and a `binary_signature` over `sig_algo: Ed25519`.
+- The manifests are **brutally honest about accuracy**: person-count's
+  `build_metadata` ships `training_class1_accuracy = 0.343` and a candid
+  `training_caveat`; pose ships `training_pck20 = 3.0` / `training_pck50 = 18.5`.
+  Nothing is inflated. That honesty *is* the anti-slop win — the models are weak
+  in the field, and the manifests say so.
+
+So the cogs **do** run real trained inference and **do** disclose how weak it is.
+What the audit correctly found were not fabrications but **claim-surface
+overclaims** — four places where the surface said more than the weights deliver.
+This ADR tightens those four (A1–A4) and cites the already-correct subsystems as
+NO-ACTION positives.
+
+Grading vocabulary follows ADR-152 / ADR-158:
+- **MEASURED** — reproduced in this worktree, command + failing-on-old test recorded.
+- **DATA-GATED** — real code path present; honestly flagged where data/hardware is absent.
+- **NO-ACTION (already-SOTA)** — audited, found correct, cited as a positive.
+- **ACCEPTED-FUTURE** — deliberately deferred, nothing dropped.
+
+## Graded SOTA Landscape
+
+| Capability | Grade | Note |
+|------------|-------|------|
+| CSI person counting (`cog-person-count`) | **DATA-GATED** | Real Candle count head + Bayesian fusion; weights trained only on classes 0/1 (presence). Multi-occupant accuracy is genuinely unproven and is **not fabricated** — counts above the trained range are now flagged `low_confidence` and clamped. |
+| CSI pose estimation (`cog-pose-estimation`) | **DATA-GATED** | Real Candle encoder + 17-keypoint head; field accuracy honestly weak (PCK@50 = 18.5%, disclosed in the manifest). The default-install gate bug (A1) is fixed so it actually emits frames. |
+| Signed cog manifests (Ed25519 + SHA-256) | **NO-ACTION (already-SOTA)** | On-disk manifests are real, signed, SHA-pinned, and honest about accuracy. The CLI now emits them verbatim (A4). |
+| HA bridge (`cog-ha-matter`) MQTT + witness | **NO-ACTION (already-SOTA)** | Real Ed25519 hash-chain witness, mDNS, embedded broker. Matter commissioning is honestly deferred to v0.8 (TLS off, LAN-only) — description softened to stop claiming Matter (honest-absence). |
+| Drone-swarm MARL (`ruview-swarm`) | **DATA-GATED / honest** | `candle_ppo.rs` is real autodiff PPO; it is **untrained at runtime** (random init) by design — the swarm must be trained before deploy, which the code does not hide. |
+| ASTM F3411 Remote ID | **MEASURED (A3)** | Basic ID message is real; the Location/Vector message is honestly *not* implemented (NED metres are no longer mislabelled as WGS84 lat/lon). |
+
+## Decision — Fixes Landed (MEASURED)
+
+### §A1 Pose runtime emitted ZERO frames under default config (HIGH)
+
+**Overclaim (silent correctness bug):** `inference.rs` hardcoded
+`confidence: 0.185` for every inference, `config.rs default_min_confidence()`
+returned `0.3`, and `runtime.rs` gated emission on `confidence >= min_confidence`.
+A default install therefore **never emitted a single `pose.frame`** while
+`health` reported healthy — the cog *claimed* to be a running pose estimator but
+silently produced nothing.
+
+**Real fix:** `pose_v1` has **no confidence head** (the head emits 34 keypoint
+coordinates only), so a real per-frame confidence is genuinely unavailable. We
+took the disclosed "ok" path rather than silently lowering the threshold:
+- Introduced `inference::MODEL_TYPICAL_CONFIDENCE = 0.185` (the validation PCK@50)
+  as the single published per-frame confidence, used by both `infer()` and the
+  config default.
+- Pinned `default_min_confidence()` to `MODEL_TYPICAL_CONFIDENCE` so a default
+  install clears its own gate and emits.
+- Documented the trade-off in the config field doc, the JSON schema
+  (`default` 0.3 → 0.185, with a description), **and** added a `run.started`
+  warning in `main.rs` that fires when an operator raises `min_confidence` above
+  the model's typical confidence — so a deliberately-high threshold is loud, not
+  silent.
+
+**Failing-on-old test:** `cog_pose_estimation` smoke
+`default_config_emits_frames_with_real_model` — parses a default config and
+asserts `min_confidence <= MODEL_TYPICAL_CONFIDENCE` (and, with the real model
+loaded, that `infer().confidence >= min_confidence`). **Proven to fail** on the
+old `default_min_confidence()=0.3`:
+`default min_confidence 0.3 exceeds model typical confidence 0.185 — a default
+install would emit zero pose.frame events`.
+
+**Grade: MEASURED.**
+
+### §A2 8-class count head on a 2-class-trained model (MEDIUM)
+
+**Overclaim:** `inference.rs COUNT_CLASSES = 8` with argmax over {0..7}, but
+`count_train_results.json` has support only for classes 0 and 1 (`per_class_accuracy`
+keys `"0"`/`"1"`). The model is a **presence detector**, not a calibrated
+multi-occupant counter; an argmax on classes 2..=7 is out-of-distribution, yet the
+cog would emit it as a confident headcount. The Cargo.toml billed it as a
+"learned multi-person counter."
+
+**Real fix (no network change — DATA-GATED, accuracy not fabricated):**
+- Added `inference::MAX_TRAINED_CLASS = 1`, plus `CountPrediction::is_low_confidence()`
+  (argmax beyond the trained ceiling) and `clamped_count()` (report clamped to the
+  trained range, raw argmax kept for audit).
+- `person.count` events now carry `low_confidence` + `raw_count`, and downgrade to
+  `level: "warn"` when out-of-distribution; the reported `count` is clamped so we
+  never emit a fabricated headcount the weights can't back.
+- `run.started` discloses `count_max_trained_class` and `count_classes`.
+- Cargo.toml description changed from "learned multi-person counter" to
+  "presence detector + (data-gated) person count".
+
+**Failing-on-old test:** `cog_person_count` smoke
+`untrained_class_argmax_is_flagged_low_confidence` — a prediction whose argmax is
+class 5 is asserted `is_low_confidence() == true` and `clamped_count() ==
+MAX_TRAINED_CLASS`; a class-1 prediction is asserted *not* flagged. Fails on old
+code (no such methods/flag existed).
+
+**Grade: MEASURED (mechanism); multi-occupant accuracy DATA-GATED.**
+
+### §A3 Remote ID broadcast NED metres as WGS84 lat/lon (MEDIUM — safety/compliance)
+
+**Overclaim (compliance hazard):** `security/remote_id.rs update()` stored
+`state.position.x/.y` (NED **metres**) into `drone_lat`/`drone_lon`, so the Remote
+ID broadcast would carry physically-impossible coordinates (e.g. "latitude =
+37.5 m"). The module doc claimed a "Basic ID + Location/Vector message," but only
+`encode_basic_id()` exists.
+
+**Real fix (honest naming — never broadcast impossible coordinates):**
+- Renamed `drone_lat`/`drone_lon` → `drone_north_m`/`drone_east_m` (NED metres
+  relative to the operator/takeoff datum), with field docs stating they are *not*
+  geodetic. `operator_lat`/`operator_lon` remain true WGS84 (from the operator's
+  GNSS).
+- Corrected the module doc to claim **Basic ID only**; the Location/Vector encoder
+  is explicitly deferred until a datum-anchored NED→WGS84 transform lands
+  (ACCEPTED-FUTURE), rather than removing a real feature.
+
+**Failing-on-old test:** `security::remote_id::tests::test_ned_offset_stored_as_metres_not_latlon`
+— a 37.5 m north / −12.0 m east NED offset is asserted to land in
+`drone_north_m`/`drone_east_m`; the operator's real WGS84 fix stays in range. Fails
+on old code, where these values were stored into `drone_lat`/`drone_lon`.
+
+**Grade: MEASURED.**
+
+### §A4 Hollow CLI manifest (LOW)
+
+**Overclaim:** `cog-person-count main.rs cmd_manifest` emitted a null skeleton
+(`binary_sha256: null`, no training metadata), making the CLI look unsigned even
+though the **real signed manifest** existed at
+`cog/artifacts/manifests/x86_64/manifest.json`.
+
+**Real fix:** new `cog_person_count::manifest` module `include_str!`-embeds the
+real signed manifests (x86_64 + arm), selected by build target arch.
+`cmd_manifest` now parses-then-emits the embedded signed manifest — exactly the
+pattern `cog-pose-estimation`'s `manifest_roundtrips` test demonstrates. The CLI
+now reports the real `binary_sha256`, `weights_sha256`, Ed25519 signature, and
+honest `build_metadata` (`training_class1_accuracy = 0.343`).
+
+**Failing-on-old test:** `manifest::tests::embedded_manifest_has_non_null_binary_sha256`
+asserts a 64-hex-char `binary_sha256`; companions assert the embedded manifest is
+signed (`sig_algo == Ed25519`) and `id == COG_ID`. End-to-end verified:
+`cog-person-count manifest` prints `binary_sha256:
+051614ce6ba63df704fae848a67ad095df4bb88862fdff05ef3c0419cc8388b3`.
+
+**Grade: MEASURED.**
+
+### §A5 cog-ha-matter description claimed Matter before it exists (LOW — honest-labeling)
+
+**Overclaim:** the Cargo.toml description said "Home Assistant + Matter
+integration," but Matter commissioning is deferred to v0.8 (`TlsConfig::Off`,
+LAN-only, asserted by `runtime.rs tls_defaults_to_off_for_v1_lan_only`).
+
+**Real fix (no code change):** softened the description to "Home Assistant (MQTT)
+integration … LAN-only (no TLS); Matter Bridge commissioning is deferred to v0.8
+and not yet implemented." Mirrors ADR-158 §6 honest-absence: state what isn't
+there rather than implying it is.
+
+**Grade: MEASURED (label).**
+
+## Negative Results (Confirmed — NO-ACTION positives)
+
+Audited and found genuinely correct; cited as positives, not edited:
+
+- **`cog-ha-matter` witness chain** (`witness.rs` / `witness_signing.rs`) — real
+  Ed25519 hash-chained witness log. Already-SOTA.
+- **`cog-person-count` fusion** (`fusion.rs`) — real Bayesian product-of-experts
+  multi-node fusion (Stoer-Wagner-bounded clip), not a heuristic. Already-SOTA.
+- **`ruview-swarm` PPO** (`marl/candle_ppo.rs`) — real Candle autodiff PPO with a
+  genuine policy-gradient update; its `randn` uses (init, action sampling,
+  exploration) are all legitimate, not fake-output substitutes. Untrained at
+  runtime by design (the swarm must be trained before deploy), which the code
+  does not hide. Already-SOTA / honest.
+
+## Deferred Backlog (Nothing Dropped)
+
+- **Multi-occupant count accuracy** — DATA-GATED on labelled multi-occupant CSI.
+  The `low_confidence` flag + clamp (§A2) is the honest stand-in until then.
+- **Remote ID Location/Vector message** — ACCEPTED-FUTURE; requires a
+  datum-anchored local-tangent-plane NED→WGS84 transform with an operator datum.
+  Basic ID ships today.
+- **Matter Bridge commissioning** — ACCEPTED-FUTURE (v0.8); LAN-only MQTT ships today.
+- **Criterion benches** for cog inference latency and `mesh_guard` — ACCEPTED-FUTURE
+  (cold-start timings are recorded in the manifests' `build_metadata`, not yet a
+  regression bench).
+- **`wasm-edge` skill accuracy** — unvalidated; **now honestly labelled, not
+  claimed** (done in ADR-160: medical/affect/security/exotic claim surfaces
+  disclaimed, renamed, and feature-gated; per-skill accuracy remains DATA-GATED).
+
+## Consequences
+
+- A default pose-estimation install now actually emits `pose.frame` events;
+  raising the threshold above the model's reach is a loud `run.started` warning,
+  not a silent dropout.
+- A person-count reading on an untrained class is flagged `low_confidence`,
+  clamped, and downgraded to `warn` — no fabricated headcounts.
+- The Remote ID broadcast can never carry physically-impossible coordinates; NED
+  metres live in honestly-named metre fields.
+- `cog-person-count manifest` now reports the real signed manifest instead of a
+  hollow null skeleton.
+- No cog Cargo.toml description claims a capability (multi-person counting, Matter)
+  the code/weights don't yet deliver.
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2
+cargo test -p cog-person-count -p cog-pose-estimation -p cog-ha-matter -p ruview-swarm \
+  --no-default-features

+# A4 end-to-end — real signed manifest, non-null binary_sha256
+cargo run -q -p cog-person-count --no-default-features -- manifest
+```
+
+Result at time of writing (all 0 failed):
+- `cog-person-count` — **19 passed** (lib 10 incl. 3 manifest; smoke 9)
+- `cog-pose-estimation` — **8 passed** (smoke)
+- `cog-ha-matter` — **64 passed** (unchanged; description-only edit)
+- `ruview-swarm` — **117 passed** (default features); `--features train` compiles clean.
+
+Scope was limited to the four named crates. NO-ACTION positives (witness chain,
+fusion, PPO + randn audit) were verified by inspection and left untouched.

+
+## Context
+
+Beyond-SOTA sweep Milestone 6, over `v2/crates/wifi-densepose-wasm-edge` only,
+executed under the project's **prove-everything / anti-"AI-slop"** directive.
+
+### Headline — 0 stubs, 0 theater, all real DSP (REFUTES the slop accusation)
+
+A read-only audit found this crate has **zero stubs and zero fake-output theater:
+every one of the ~70 edge skills runs real DSP** (Welford statistics,
+autocorrelation, DTW, sliced-Wasserstein, ISTA-style recovery, Kalman/HNSW, etc.).
+The forward paths are genuine signal processing on real CSI-derived inputs. That
+is the anti-slop win and it is cited here as a positive, not a fabrication.
+
+What the audit correctly found was **not fake code but an over-confident claim
+surface**: skill *names* and doc-comments asserting clinical/affective/security
+capabilities that the **unvalidated** code cannot back, concentrated in the
+medical (`med_*`) and affect (`exo_happiness`/`exo_emotion`) skills. The fix is
+**honest labeling — making the labels TRUE — NOT making the claimed capability
+real.** You cannot validate seizure detection, affect inference, or weapon
+discrimination without clinical/labelled data and reference standards; this ADR
+does not pretend to. It disclaims, renames, softens, and feature-gates so the
+surface matches what the DSP actually delivers.
+
+Grading vocabulary follows ADR-152 / ADR-158 / ADR-159:
+- **MEASURED** — reproduced in this worktree, command + failing-on-old test recorded.
+- **DATA-GATED** — real code path present; honestly flagged where data is absent.
+- **NO-ACTION (already-honest)** — audited, found correct, cited as a positive.
+- **ACCEPTED-FUTURE** — deliberately deferred, nothing dropped.

+
+## Decision — Fixes Landed
+
+### §A1 Medical overclaim (HIGH) — MEASURED
+
+The five `med_*` modules (`med_seizure_detect`, `med_cardiac_arrhythmia`,
+`med_respiratory_distress`, `med_sleep_apnea`, `med_gait_analysis`) stated clinical
+detection as fact with no disclaimer ("Detects tonic-clonic seizures…").
+
+**Real fix (honest labeling — the DSP is kept, untouched):**
+- **(a)** Every module's `//!` header now carries a mandatory disclaimer block,
+  modelled on `sec_weapon_detect.rs` and `nvsim/src/lib.rs`: *"EXPERIMENTAL
+  RESEARCH MODULE — NOT VALIDATED AGAINST CLINICAL DATA. NOT A MEDICAL DEVICE.
+  Flags candidate <X>-like signatures only,"* citing ADR-160.
+- **(b)** Doc verbs softened: *"Detects tonic-clonic seizures"* →
+  *"Flags candidate tonic-clonic-seizure-like motion signatures (experimental)"*;
+  similarly for cardiac/respiratory/apnea/gait.
+- **(c)** All five gated behind a new **non-default** cargo feature
+  `medical-experimental` (`#[cfg(feature = "medical-experimental")]` in `lib.rs`,
+  `medical-experimental = []` in `Cargo.toml`, **not** in `default`) so they cannot
+  be silently built into a shipping artifact.
+
+**Failing-on-old tests** (`tests/honest_labeling.rs`):
+`a1_med_modules_have_clinical_disclaimer`,
+`a1_med_modules_gated_behind_medical_experimental`,
+`a1_seizure_verbs_softened`. All fail on the old, undisclaimed, ungated source.
+**Grade: MEASURED (label); per-skill clinical accuracy DATA-GATED.**
+
+### §A2 Affect overclaim (HIGH) — MEASURED
+
+`exo_happiness_score.rs` carried an **uncited** "Happy people walk ~12% faster"
+statistic and emits `HAPPINESS_SCORE`; `exo_emotion_detect.rs` emits
+`STRESS_INDEX`/`CALM_DETECTED`/`AGITATION_DETECTED`.
+
+**Real fix (honest labeling — math kept):**
+- Deleted the uncited "12% faster" / "~12% above" / "Happy people walk" statements.
+- Added a prominent *"speculative, unvalidated affect heuristic; outputs are NOT
+  measurements of emotion"* disclaimer to both `//!` headers, citing ADR-160.
+- Reframed `HAPPINESS_SCORE` in the docs as a **"gait-energy proxy, not a validated
+  affect measure."**
+
+**Failing-on-old tests:** `a2_affect_modules_have_unvalidated_disclaimer`,
+`a2_uncited_12_percent_stat_removed`, `a2_happiness_reframed_as_proxy`.
+**Grade: MEASURED (label); affect validity DATA-GATED.**
+
+### §A3 Security event-name overclaim (MEDIUM) — MEASURED
+
+`sec_weapon_detect.rs`'s module doc was already honest (research-grade,
+calibration-required), but the event/const names claimed weapon-grade
+discrimination a variance ratio cannot deliver.
+
+**Real fix (honest physical-quantity naming — behavior unchanged):**
+- `EVENT_WEAPON_ALERT` → `EVENT_HIGH_METAL_REFLECTIVITY` (event id 221 unchanged).
+- `WEAPON_RATIO_THRESH` → `HIGH_REFLECTIVITY_THRESH`.
+- Internal fields/consts renamed (`weapon_run`→`high_refl_run`,
+  `cd_weapon`→`cd_high_refl`, `WEAPON_DEBOUNCE`→`HIGH_REFLECTIVITY_DEBOUNCE`).
+- `lib.rs` `event_types` registry: `WEAPON_ALERT` → `HIGH_METAL_REFLECTIVITY`.
+- A reflectivity-vs-weapons honest-naming note added to the header.
+The detector still flags a high amplitude-variance/phase-variance ratio (real RF
+reflectivity); it just no longer *names* that "weapon".
+
+**Failing-on-old tests:** `a3_weapon_names_renamed_to_reflectivity`,
+`a3_registry_no_longer_exports_weapon_alert` (registry no longer exports a
+`WEAPON_ALERT` name). **Grade: MEASURED.**
+
+### §A4 Quasi-medical / sign-language exotic modules (MEDIUM) — MEASURED
+
+`exo_dream_stage.rs` ("sleep stage classification", quasi-medical) and
+`exo_gesture_language.rs` ("sign language letter recognition").
+
+**Real fix (honest labeling — DSP kept):** added an experimental "NOT VALIDATED"
+disclaimer to each `//!` header (citing ADR-160) and promoted the
+**Exotic/Research** registry tag into the header where a reader sees it.
+`exo_gesture_language` additionally states it is a coarse gesture-cluster
+classifier that **does not recognize true sign language** (never evaluated on a
+labelled ASL set).
+
+**Failing-on-old test:** `a4_exotic_modules_have_experimental_disclaimer`.
+**Grade: MEASURED (label); accuracy DATA-GATED.**
+
+### §A5 `static mut` event-buffer soundness (MEDIUM) — the one real code fix — MEASURED
+
+~61 per-call event scratch buffers across the crate used a module-level
+`static mut EVENTS: [(i32,f32); N]` (a handful named `EV`/`TE`/`EMPTY`) and returned
+`&EVENTS[..n]`. On a `cdylib`+`rlib` linkable into multithreaded/reentrant host
+code this is latent aliasing UB, and `static_mut_refs` is deny-by-default on newer
+Rust.
+
+**Real fix (mechanical, behavior-preserving):** moved each scratch buffer off
+`static mut` into an **owned per-instance field** (`events: [(i32,f32); N]` on the
+detector struct, written via `&mut self` and returned as `&self.events[..n]`). The
+public `-> &[(i32, f32)]` signature is **unchanged**, so no caller (in-module
+tests, `ghost_hunter` bin, `budget_compliance`) needed editing. Two helper methods
+that built events under `&self` (`spt_pagerank_influence::build_events`,
+`spt_spiking_tracker::build_events`) and `sig_temporal_compress::on_timer` were
+promoted to `&mut self`. Leftover now-redundant `unsafe { }` wrappers were removed.
+
+**Count: 61 scratch buffers across 60 module files fixed** (the only `static mut`
+left in `src/` are the two **legitimate WASM module singletons** — `lib.rs STATE`
+and `bin/ghost_hunter.rs DETECTOR` — `#[cfg(target_arch="wasm32")]`,
+`#[no_mangle]`, accessed via `core::ptr::addr_of_mut!`, single-threaded by the
+wasm runtime contract; these are *not* the aliasing-UB scratch pattern and are
+left as-is).
+
+**Verification:** the full host build (`--features std` and
+`std,medical-experimental`) compiles with **0 warnings** — there is no longer any
+`static mut <name>` + `&<name>` source for `static_mut_refs` to fire on in the 60
+fixed modules. (The pure-`wasm32-unknown-unknown` build, where the lint is
+deny-by-default, could not be run in this worktree because the `wasm32` target is
+not installed on the build toolchain; the source-level elimination is the
+evidence, asserted per-module by `a5_claim_bearing_modules_have_no_static_mut_event_buffer`.)
+**Grade: MEASURED (source-eliminated; residual = 2 legitimate singletons).**
+
+## Negative Results (NO-ACTION positives — cited, not edited for labels)
+
+Audited and found genuinely honest; cited as positives:
+- **`qnt_quantum_coherence.rs`** — discloses "quantum-**inspired**" analogy.
+- **`exo_time_crystal.rs`**, **`exo_ghost_hunter.rs`** — disclosed exploratory/novelty.
+- **`qnt_interference_search.rs`** — disclosed "Grover-**inspired**".
+- **`sig_*` / `lrn_*`** algorithm-named skills — names describe the DSP, not an outcome.
+- **`nvsim`** — out of scope; the project's disclaimer gold standard (its tone was
+  copied into the A1/A2/A4 disclaimers).
+
+(These were A5-soundness-fixed mechanically where they used `static mut`, with no
+label or behavior change, consistent with leaving their claim surface intact.)
+
+## Deferred Backlog (Nothing Dropped)
+
+- **Per-skill accuracy validation** — **PARTIALLY MEASURED-on-synthetic**
+  (2026-06-13). For the subset of skills whose detection target is *constructible*
+  with known ground truth, a synthetic-ground-truth harness
+  (`tests/synthetic_validation.rs`, 12 tests) plants signals with known answers,
+  runs the real detector, and **measures** detection accuracy / rate-error:
+  `vital_trend`, `exo_time_crystal` (periodic-vs-aperiodic — its sub-harmonic-vs-
+  clean-period claim is NOT separable, recorded honestly), `exo_ghost_hunter`
+  (hidden breathing), `occupancy`, `intrusion`, `exo_rain_detect`,
+  `sig_flash_attention` (8/8 peak localization), `spt_spiking_tracker` (4/4 zone
+  localization, sparse plant), `sig_optimal_transport`, `sig_mincut_person_match`
+  (0 id-swaps), `lrn_dtw_gesture_learn` (enrollment) — all 1.000 where claimed;
+  `sig_sparse_recovery`'s recovery accuracy is reported **negative** (−2.2% vs
+  unrecovered baseline) — only its trigger path is validated. Full numbers +
+  reproduce commands in `benchmarks/edge-skills/RESULTS.md`.
+  The **med_*/affect/sign-language/weapon** claims remain **DATA-GATED**:
+  validating them requires labelled clinical/affective/ASL/metal-object data and
+  reference standards that do not exist in this repo. Planting a "seizure-/weapon-/
+  happy-like" synthetic signal validates nothing real and is explicitly refused;
+  RESULTS.md lists each with the real data it needs. The disclaimers + feature gate
+  are the honest stand-in. Nothing is claimed that is not measured.
+- **Unified edge pipeline** — **MEASURED** (2026-06-13). `src/pipeline_all.rs`
+  (`EdgePipeline`) + `src/skill_registry.rs` register **every** runtime skill
+  behind one uniform `EdgeSkill` trait and run them all per CSI frame; `med_*` are
+  registered only under `--features medical-experimental` (preserves the §A1 gate).
+  `tests/pipeline_all.rs` (4 tests) proves all 59 default / 64 medical skills run
+  without panic over 300 synthetic frames with a well-formed aggregated event
+  stream. `examples/run_all_skills.rs` is a runnable demo. No skill DSP changed.
+- **Criterion benches for `process_frame` budget claims** — **DONE (host)**
+  (ADR-163, 2026-06-12). `benches/process_frame_bench.rs` benches the heaviest
+  hot paths (`exo_time_crystal` 256×128 autocorrelation, `exo_ghost_hunter`
+  periodicity, `sec_weapon_detect` per-subcarrier Welford, `med_seizure_detect`
+  clonic rhythm) and reports committed **host** medians
+  (`benchmarks/edge-latency/RESULTS.md`). `tests/budget_compliance.rs` continues
+  to assert the L/S/H tier wall-clock budgets (25 tests, passing). **ESP32-on-
+  hardware (Xtensa/WASM3) latency remains PENDING** — the host bench is an
+  upper-bound algorithm-cost proxy, NOT the ESP32 figure (needs hardware).
+- **`wasm32-unknown-unknown` `static_mut_refs` confirmation** — **ACCEPTED-FUTURE**
+  (toolchain): the source pattern is eliminated; a CI job on the wasm target should
+  assert zero `static_mut_refs` once the target is added to the build image.
+- **The 2 residual `static mut` singletons** (`lib.rs STATE`, `ghost_hunter DETECTOR`)
+  — **ACCEPTED-FUTURE**: these are the canonical wasm module-state pattern; migrating
+  them to a safe cell is a separate, larger change with no current UB (single-threaded
+  wasm runtime, `addr_of_mut!` access).
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2/crates/wifi-densepose-wasm-edge   # excluded from the v2 workspace; build here
+cargo test --features std                          # default

+cargo test --no-default-features --features std     # no default-pipeline
+cargo test --features std --test honest_labeling   # A1–A5 label invariants
+```
+
+(`std` is required for host tests — the crate is `no_std` for `wasm32`; pure
+`--no-default-features` builds only on `wasm32-unknown-unknown`, where it
+intentionally has no panic handler on the host.)
+
+Result at time of writing (all 0 failed):
+- **DEFAULT** (`--features std`) — **615 passed** (lib 504; budget 25; honest_labeling 10; bench 1; vendor 75)
+- **MEDICAL** (`--features std,medical-experimental`) — **653 passed** (lib 542; +38 med_* tests; others unchanged)
+- **NO-DEFAULT** (`--no-default-features --features std`) — **615 passed**
+- Full host build emits **0 warnings**; **61** `static mut` scratch buffers eliminated, **2** legitimate wasm singletons remain.
+
+## Consequences
+
+- No edge skill's name or doc-comment claims a clinical, affective, security, or
+  sign-language capability the unvalidated DSP cannot back.
+- The five medical skills cannot be silently compiled into a shipping artifact
+  (non-default `medical-experimental` gate).
+- The security skill can never emit a "weapon alert" — it reports
+  `HIGH_METAL_REFLECTIVITY`, the physical quantity it actually measures.
+- The latent `static mut` aliasing-UB / `static_mut_refs` exposure is removed from
+  60 modules; the public API and all runtime behavior are unchanged (615/653 tests
+  prove behavior preservation).

+# ADR-161: HOMECORE Server Layer — WebSocket Auth Bypass, Reply-Theater & Documented-but-No-Op Automation (Security & Honest Labeling)

+- **Status**: accepted

+- **Deciders**: ruv
+- **Tags**: homecore, http-ws-boundary, websocket-auth-bypass, security, automation-engine, documented-no-op, prove-everything, soundness, honest-labeling

+
+## Context
+
+Beyond-SOTA sweep **Milestone 7**, over the HOMECORE **server/network layer**
+crates only — `homecore-api`, `homecore-server`, `homecore-automation`,
+`homecore-hap`, `homecore-plugins` — executed under the project's
+**prove-everything / anti-"AI-slop"** directive.
+
+### Headline — the library cores are real, but the network boundary was unsound
+
+The same audit pattern as ADR-160 held for the *library logic*: the automation
+trigger/condition/template/action evaluators, the REST handlers, the HAP
+mapping, and the plugin manifest parser are **real, tested code** — not stubs.
+That is the anti-slop positive and it is cited here as such.
+
+What the audit found was **not fake business logic but an unsound trust
+boundary plus documented-but-no-op features**:
+
+1. A **CRITICAL WebSocket authentication bypass** — the WS handshake accepted
+   any non-empty token, ignoring the provisioned token whitelist the REST path
+   enforces.
+2. **Reply-theater** — WS command responses were computed, then logged and
+   **discarded**; no `result`/`pong`/`event` ever reached the client.
+3. **Documented-but-idle automation** — the engine was constructed and dropped
+   (never started); time triggers, `RunMode`, `Choose` branches, and template
+   conditions were each **documented as working but were no-ops in the live
+   path**.
+
+This is a worse class than ADR-160's over-naming: here the **doc claimed a
+capability the code did not deliver** (auth enforcement, reply transport,
+running automations). The fix is **implement where feasible, honestly relabel
+where not — never leave a false doc.** Every fix is pinned by a test that
+**fails on the old code**.

+- **ACCEPTED-FUTURE** — deliberately deferred, nothing dropped.
+
+## Decision — Fixes Landed
+
+### §A1 — WebSocket auth bypass (CRITICAL, security) — MEASURED
+
+`homecore-api/src/ws.rs` handshake checked only `token.trim().is_empty()` and
+sent `auth_ok` for **any** non-empty token. 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:<n>` 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<AtomicBool>`.
+`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. No verification
+code was added (that is P4); the doc now matches the code.
+**Grade: doc-honesty (no behavior change).** *(Superseded by ADR-162 §P4:
+the hash/signature gate is now implemented and enforced.)*
+
+## Negative Results (NO-ACTION positives — audited, found correct, cited not edited)
+
+These were checked and are genuinely sound/honest; cited as positives, **not**
+touched:
+- **CSPRNG correctness** — all IDs are `uuid::v4`; the rng/`randn` suspicion was
+  **REFUTED**. No weak-randomness issue exists.
+- **CORS allowlist** (`app.rs`) — already hardened (explicit `AllowOrigin::list`,
+  no `permissive()`, `allow_credentials(false)`, env override). NO-ACTION.
+- **No path traversal in `homecore-migrate`** — audited, clean.
+- **No secrets in logs** — audited, clean.
+- **HAP pairing stub** — honestly disclaimed as a surface stub; not over-claimed.
+- **`InProcessRuntime` "no sandbox" disclaimer** — honest; left as-is.
+
+## Deferred Backlog (Nothing Dropped)
+
+- **Plugin authority-isolation (P5)** — ~~`homecore_permissions` claims are parsed
+  but not enforced at the host-call boundary.~~ **DONE — ADR-162 §P5.**
+  `hc_state_set` now consults a `PermissionSet` distilled from the manifest;
+  an undeclared write returns a typed `-3` to the guest.
+- **Plugin signature/hash verification (P4)** — ~~implement the
+  `wasm_module_hash`/`wasm_module_sig`/`publisher_key` gate that B5 now honestly
+  says is absent.~~ **DONE — ADR-162 §P4.** `WasmtimeRuntime::load_plugin` now
+  SHA-256-checks the module, Ed25519-verifies the signature against
+  `publisher_key`, and enforces a `PluginPolicy` trust allowlist
+  (secure-default rejects unsigned/untrusted/tampered modules).
+- **HAP real pairing (P2)** — SRP/HKDF pairing + encrypted sessions; current
+  bridge is an accessory-mapping surface. **ACCEPTED-FUTURE (honestly stubbed).**
+- **`RunMode::Queued`/`Restart`/`max` ordering** — ~~`Single`/`Parallel` are
+  honored; bounded queueing, restart-kill, and `max` concurrency are not yet
+  wired (every non-Single mode is parallel).~~ **DONE — ADR-162 §A5.** Restart
+  aborts the in-flight task, Queued serializes via a per-automation async mutex,
+  and `max: N` caps concurrency via a per-automation semaphore.
+- **Automation YAML load-at-boot** — the engine starts empty; a YAML loader is
+  P-next. The bin log states "0 automations registered" honestly.
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2
+cargo test -p homecore-api -p homecore-server -p homecore-automation -p homecore-hap --no-default-features
+cargo test -p homecore-plugins --features wasmtime
+cargo build --workspace --no-default-features
+```
+
+Result at time of writing (all 0 failed):
+- **homecore-api** — **25 passed** (lib 18; `server_bin_auth` 3; `ws_handshake` 4)
+- **homecore-automation** — **42 passed** (lib 37; `engine_behaviors` 5)
+- **homecore-hap** — **17 passed**
+- **homecore-server** — bin, **0 tests**
+- (**homecore-plugins** — **15 passed**: lib 12; integration 3)
+- Full workspace `cargo build --workspace --no-default-features` succeeds.
+
+## Consequences
+
+- The WebSocket path can no longer be entered with a forged token — it enforces
+  the same `LongLivedTokenStore` whitelist as REST (A1).
+- WS clients now actually receive `result`/`pong`/`event` frames (A2).
+- The `homecore-api` dev bin defaults to loopback and honors `HOMECORE_TOKENS`
+  (A8); it is no longer an open `0.0.0.0` accept-any endpoint by default.
+- The automation engine is started for real and its time triggers, `Single`
+  run-mode, `Choose` branches, and `template:` conditions all function — no doc
+  claims a capability the code lacks (A3–A7).
+- The plugin manifest no longer claims signature verification it does not
+  perform (B5).
+- Files kept under the 500-line guideline (`engine.rs` 462; behavioral tests
+  moved to `tests/engine_behaviors.rs`).
+
+## Addendum — `homecore-api` follow-up security review (beyond-SOTA pass)
+
+A later network-facing review of `homecore-api` (the remote REST + WS attack
+surface) — independent of the ADR-154–159 sweep — found and fixed two real
+issues the original M7 pass (which focused on the WS auth bypass HC-WS-01, the
+reply-theater HC-WS-02, and the bin token provisioning HC-WS-08) did not catch.
+Both are LOW severity and reported at true severity.
+
+### HC-API-AUTH-01 — `GET /api/` was unauthenticated (FIXED)
+
+`rest::api_root` took no headers and unconditionally returned
+`200 {"message":"API running."}`, while every sibling route gates on
+`BearerAuth::from_headers`. HA's `APIStatusView` inherits `requires_auth = True`,
+so `/api/` must return **401** for a missing/wrong bearer. HA clients use the
+status route as a token-validation probe; a 200 told a bad-token client its
+token was valid and let an unauthenticated party confirm a live endpoint.
+LOW severity (the body is a static string; no entity/state data leaks).
+
+**Fix:** `api_root(headers, State)` now validates the bearer like `get_config`.
+**Pinned by** (fail-on-old, `tests/server_bin_auth.rs`):
+`api_root_rejects_missing_bearer`, `api_root_rejects_wrong_bearer` (both 200→401),
+guarded by `api_root_accepts_correct_bearer` (still 200 with a valid token).
+
+### HC-WS-LAG-01 — `subscribe_events` killed the stream on a broadcast lag (FIXED)
+
+The per-subscription task matched `Err(_) => break` on both broadcast
+`recv()` arms. `RecvError::Lagged(n)` (a slow consumer falling
+>`EVENT_CHANNEL_CAPACITY` = 4,096 events behind) is **recoverable** — the bus
+doc says "Lagged receivers must re-sync" and HA 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 of the `select!`.
+**Pinned by** `subscription_survives_broadcast_lag` (`tests/ws_handshake.rs`):
+subscribes to a filtered event type, floods 6,000 unrelated events past the
+4,096 capacity to force a `Lagged`, then asserts a subsequent subscribed event
+is still delivered (old code: 5s-timeout panic).
+
+### Dimensions confirmed clean (with evidence)
+
+- **AuthN/AuthZ** — all 7 other REST handlers gate on `BearerAuth::from_headers`
+  → `LongLivedTokenStore::is_valid` before any work; the WS handshake validates
+  the `auth` token against the same store before the command loop, and
+  privileged commands are unreachable pre-`auth_ok`. Token compare is
+  `HashSet::contains` (content-independent timing — not the byte-`==` oracle of
+  ADR-157 §B4), so no timing-oracle finding. No route skips the gate; no
+  result-ignored check; no default/empty token accepted.
+- **Path traversal** — no route maps user input to a filesystem path (state is an
+  in-memory `DashMap`); `:entity_id` passes through `EntityId::parse`, a strict
+  `[a-z0-9_]+\.[a-z0-9_]+` ASCII allowlist that rejects `..`, `/`, `\`, and
+  absolute paths. No traversal surface.
+- **Injection** — no SQL, no shell/subprocess, no `format!`-into-response;
+  service/state bodies are typed `serde_json::Value` handed to the in-process
+  registry (HA-equivalent).
+- **Info-leak** — `ApiError` maps to fixed status + a typed `{message}`;
+  `ServiceError::HandlerFailed(String)` is integration-controlled (HA surfaces
+  the handler error too), never framework internals/paths/stack-traces — no
+  ADR-080-class leak.
+- **CORS** — explicit allowlist with `allow_credentials(false)` (HC-05),
+  not `permissive()`.
+- **De-magic** — no bare security-relevant literals in the crate worth
+  extracting (`EVENT_CHANNEL_CAPACITY` is already named in `homecore`; CORS
+  dev-default ports are documented).
+
+**Tests:** `homecore-api --no-default-features` **25 → 29** (+2 api-root auth,
+1 api-root accept-guard, +1 WS lag-survival), 0 failed. Workspace green.
+Python deterministic proof unchanged (homecore-api is off the signal proof
+path).

+# ADR-162: HOMECORE Plugin Security (Signature + Capability Isolation) & Bounded Automation RunModes — Making ADR-161's Deferred Claims TRUE
+
+- **Status**: accepted
+- **Date**: 2026-06-12
+- **Deciders**: ruv
+- **Tags**: homecore, homecore-plugins, homecore-automation, plugin-security, wasm-signature-verification, ed25519, capability-isolation, runmode, prove-everything, soundness, honest-labeling
+- **Amends**: ADR-161 (relabelled P4/P5 + §A5 deferrals → now enforced), ADR-128 (plugin manifest), ADR-129 (automation engine)
+
+## Context
+
+Beyond-SOTA sweep **Milestone 8**, scoped to `homecore-plugins` and
+`homecore-automation` only, under the project's **prove-everything /
+anti-"AI-slop"** directive.
+
+ADR-161 (Milestone 7) did the honest thing with three plugin/automation
+items it could not finish in that window: rather than fake them, it **relabelled
+them as deferred** —
+
+- **P4** (plugin signature verification): the manifest's `wasm_module_hash` /
+  `wasm_module_sig` / `publisher_key` were re-doc'd "(P4 — not yet enforced,
+  ADR-161/B5)" — parsed and round-tripped, but **never checked** before a
+  plugin runs.
+- **P5** (plugin authority isolation): `homecore_permissions` claims were
+  parsed but **never consulted**; `hc_state_set` let any plugin write any
+  entity, including `lock.*` / `alarm_control_panel.*`.
+- **§A5** (`RunMode`): `Single`/`Parallel` were honored; `Restart`/`Queued`/
+  `max: N` were honestly documented as still **unbounded-parallel**.
+
+### Headline — the deferred security items are now ENFORCED + TESTED
+
+M8 turns those honest deferrals into real, tested behavior. The plugin trust
+boundary is now sound (a tampered module, an untrusted publisher, or an
+unsigned module is rejected by the secure default), an over-privileged plugin
+write is denied with a typed error, and the bounded run-modes actually bound.
+**Every fix is pinned by a test that FAILS on the pre-M8 code** — each of the
+three RunMode tests was additionally run against a simulated unbounded-parallel
+dispatch and confirmed to panic.
+
+The Ed25519 crypto reuses the in-repo `cog-ha-matter::witness_signing` pattern
+(same `ed25519-dalek` 2.x API, same deterministic-test-key convention). SHA-256
+matches the `sha256:` prefix the manifest already declared and the
+`cog-ha-matter` cog manifest's `binary_sha256` hex convention. No new external
+dependency tree was introduced — `ed25519-dalek` / `sha2` / `hex` / `base64`
+were already in the workspace `Cargo.lock` (cog-ha-matter / bfld pull them in);
+only new dependency *edges* were added to `homecore-plugins`.
+
+Grading vocabulary (ADR-152 / ADR-158 / ADR-160 / ADR-161):
+- **MEASURED** — reproduced in this worktree, command + failing-on-old test recorded.
+- **ACCEPTED-FUTURE** — deliberately deferred, nothing dropped.
+
+## Decision — Fixes Landed
+
+### §P4 — Plugin signature & integrity verification (SECURITY) — MEASURED
+
+`homecore-plugins/src/manifest.rs` declared `wasm_module_hash` /
+`wasm_module_sig` / `publisher_key` but they were **never read** for
+verification; the load path (`wasmtime_runtime.rs`) instantiated any `.wasm`
+bytes handed to it.
+
+**Real fix** (`src/verify.rs`, wired into `WasmtimeRuntime::load_plugin`):
+before instantiation the runtime now —
+
+1. computes the **SHA-256** of the actual `.wasm` bytes and rejects if it ≠ the
+   manifest's `wasm_module_hash` (`sha256:<hex>`) — tamper detection;
+2. verifies the **Ed25519** `wasm_module_sig` (`ed25519:<base64>`, 64-byte raw)
+   over the 32-byte digest against `publisher_key` (`ed25519:<base64>`, 32-byte
+   raw) and rejects on failure;
+3. enforces a configurable **trust policy** — `PluginPolicy::trusted(&[keys])`
+   is an allowlist of publisher verifying keys; `PluginPolicy::AllowUnsigned`
+   is an explicit dev escape hatch that LOGS a loud `warn` on every load it
+   waves through. The **secure default rejects unsigned and unknown-publisher
+   modules.** `PluginPolicy::deny_all()` trusts no publisher.
+
+A typed `PluginError::SignatureRejected` is returned (no host panic). The
+legacy permission-free `load_wasm` is retained for first-party/trusted/test
+modules; production loading goes through `load_plugin`.
+
+**Failing-on-old tests** (`tests/integration.rs`, `--features wasmtime`) — all
+drive `load_plugin`, which **did not exist** on the old code (so the gate is
+genuinely new):
+- `p4_tampered_module_is_rejected` — a byte-flipped `.wasm` → hash mismatch → rejected.
+- `p4_valid_sig_from_trusted_key_loads` — a valid sig from an allowlisted key loads.
+- `p4_valid_sig_from_untrusted_key_is_rejected` — a correctly-signed module from a key NOT on the allowlist is rejected.
+- `p4_unsigned_module_rejected_by_default_loads_only_under_allow_unsigned` — unsigned rejected under `deny_all`, loads (with warn) only under `AllowUnsigned`.
+- Unit (`src/verify.rs`): `valid_sig_from_trusted_key_passes`, `tampered_module_is_rejected`, `valid_sig_from_untrusted_key_is_rejected`, `forged_signature_is_rejected`, `unsigned_module_rejected_under_default_policy`.
+
+A real deterministic keypair signs real `.wasm` bytes in the tests.
+The manifest doc now reads **"(P4 — ENFORCED, ADR-162)"**. **Grade: MEASURED. Milestone headline.**
+
+### §P5 — Plugin authority / capability isolation (SECURITY) — MEASURED
+
+`wasmtime_runtime.rs::hc_state_set` applied any write a plugin requested,
+ignoring the manifest's `homecore_permissions`.
+
+**Real fix** (`src/permissions.rs` + `hc_state_set`): the manifest's
+`homecore_permissions` (the `state:write:<glob>` form, or a bare entity glob
+like `light.*`) are distilled into a `PermissionSet` installed in the plugin's
+Wasmtime store. The `hc_state_set` host import consults
+`permissions.may_write(entity_id)` before applying a write and returns a typed
+`-3` (permission denied) to the guest on a violation — **the host is not
+panicked.** Wasmtime already gives memory isolation; this adds **authority**
+isolation. A plugin with **no** write grants can write nothing (secure default).
+
+**Failing-on-old tests** (`tests/integration.rs`, `--features wasmtime`):
+- `p5_declared_light_plugin_may_write_light_but_not_lock` — a `light.*` plugin writes `light.kitchen` (succeeds) but is REJECTED (`-3`, and the entity is not written) when it tries `lock.front_door`.
+- `p5_plugin_with_no_permissions_can_write_nothing` — a plugin with empty `homecore_permissions` cannot write `light.kitchen`.
+- Unit (`src/permissions.rs`): domain-glob, exact-grant, wildcard, read-grants-don't-confer-write, no-permissions, and explicit `state:write:` form.
+
+The manifest doc now reads **"(P5 — ENFORCED, ADR-162)"**. **Grade: MEASURED.**
+
+### §A5 — Bounded automation RunModes (Restart / Queued / max) — MEASURED
+
+`homecore-automation/src/engine.rs` (per ADR-161) honored `Single`/`Parallel`
+but spawned an unbounded parallel task for `Restart`/`Queued`/`max`.
+
+**Real fix** (`src/runmode.rs`, a per-automation `RunState` the engine owns and
+dispatches through at all three trigger sites — event loop, timer, test hook):
+- **Restart** — aborts the in-flight action task via `tokio::task::AbortHandle`, then starts a fresh one.
+- **Queued** — serializes runs in arrival order via a per-automation async `Mutex`: sequential, never concurrent, nothing dropped.
+- **max: N** — caps concurrency at N via a per-automation `Semaphore`; triggers beyond N **queue** (await a permit) rather than running concurrently. (HA bounded `parallel`/`queued` semantics — chosen and documented as *queue beyond N*, not drop.)
+- `Single`/`IgnoreFirst` re-entrancy guard and `Parallel` preserved.
+
+`engine.rs` trimmed to **433 lines**; the run-mode machinery lives in the new
+`runmode.rs` (153 lines) to keep both under the 500-line guideline.
+
+**Failing-on-old tests** (`tests/engine_behaviors.rs`) — each was run against a
+simulated unbounded-parallel dispatch and confirmed to panic:
+- `restart_mode_cancels_prior_run` — prior run is aborted: exactly **1** completion (old: both ran → 2).
+- `queued_mode_runs_sequentially_not_concurrently` — 3 rapid triggers all run, **max observed concurrency = 1** (old: 3).
+- `max_two_caps_concurrency_at_two` — 4 rapid triggers all run, **max observed concurrency ≤ 2** (old: 4).
+
+**Grade: MEASURED. Restart, Queued, and `max: N` all implemented — no remaining RunMode deferral.**
+
+## Threat model closed
+
+| Threat | Before (ADR-161) | After (ADR-162) |
+|--------|------------------|-----------------|
+| **Tampered module** — attacker swaps `.wasm` bytes after signing | loaded unconditionally (hash never checked) | rejected: SHA-256 mismatch |
+| **Untrusted publisher** — valid sig from a key the host doesn't trust | loaded (sig/key never read) | rejected: publisher_key not on allowlist |
+| **Unsigned module** — no integrity material at all | loaded | rejected by secure default; loads only under explicit `AllowUnsigned` (loud warn) |
+| **Over-privileged plugin write** — a `light.*` plugin writes `lock.front_door` / `alarm_control_panel.*` | applied (permissions never consulted) | denied: typed `-3` to guest, write not applied |
+| **Run-mode resource exhaustion** — `max`/`Queued` spawn unbounded tasks | unbounded parallel | bounded: Restart cancels, Queued serializes, `max: N` caps at N |
+

+
+- **Plugin-key provisioning / rotation** — the host's trust allowlist
+  (`PluginPolicy::trusted`) is supplied by the caller; sourcing it from the
+  Cognitum control-plane key store (as `cog-ha-matter` does for Seed keys) and
+  key rotation are **ACCEPTED-FUTURE** (out of M8 scope — same boundary
+  `witness_signing` draws).
+- **`InProcessRuntime` (native first-party plugins)** — has no `.wasm` bytes to

+
+Result at time of writing (all 0 failed):
+- **homecore-plugins** `--features wasmtime` — **32 passed** (lib 23; integration 9). (ADR-161 baseline was 15.)
+- **homecore-automation** `--no-default-features` — **45 passed** (lib 37; `engine_behaviors` 8). (ADR-161 baseline was 42.)
+- Full workspace `cargo build --workspace --no-default-features` succeeds.
+
+## Consequences
+
+- A HOMECORE WASM plugin can no longer be loaded with a tampered binary, an
+  untrusted publisher, or (by default) no signature at all — the trust boundary
+  ADR-161/B5 honestly said was absent is now real (P4).
+- A plugin can no longer write entities outside its declared
+  `homecore_permissions`; the lock/alarm escalation path is closed (P5).
+- The automation engine's `Restart`, `Queued`, and `max: N` run-modes are now
+  bounded as documented — no run-mode claims a capability the code lacks.
+- No new external dependency tree (reuses the cog-ha-matter Ed25519 stack
+  already in the lock); source files kept under the 500-line guideline

+# ADR-163: Edge-Latency Measurement — CLAIMED budgets → MEASURED-on-host
+
+- **Status**: accepted
+- **Date**: 2026-06-12
+- **Deciders**: ruv
+- **Tags**: edge-latency, wasm-edge, esp32, cog-inference, criterion, prove-everything, measurement-debt
+- **Amends**: ADR-160 (deferred "criterion benches for process_frame budget claims" line now DONE-on-host); ADR-159 (cog inference latency)
+
+## Context — Milestone 9 of the beyond-SOTA sweep
+
+Prior milestones (M5/M6, ADR-159/ADR-160) flagged **measurement debt**: edge
+latency budgets asserted in doc-comments and manifests but **never reproduced by
+a committed benchmark**. Specifically:
+
+- Many `wifi-densepose-wasm-edge` skill modules document a timing budget *"on
+  ESP32-S3 WASM3"* (e.g. `exo_time_crystal`: "H (heavy, <10 ms)"). These were
+  **CLAIMED**, not benchmarked. ADR-160's deferred backlog named exactly this:
+  *"Criterion benches for `process_frame` budget claims — ACCEPTED-FUTURE."*
+- `cog-pose-estimation`'s manifest cites `cold_start_ms_avg: 5.4`, but neither
+  cog had a `benches/` directory or any committed inference-latency number.
+
+Under the project's **prove-everything / anti-"AI-slop"** directive, a CLAIMED
+latency budget that a skeptic cannot reproduce is debt. M9 pays it down — benches
+and docs only, **no production-code behavior change** (so nothing republishes).
+
+## Headline
+
+**Converted the CLAIMED edge-latency budgets into MEASURED-on-host numbers, with
+the honest host-vs-ESP32 caveat stated everywhere.** Added committed criterion
+benches over the heaviest hot paths and a results file a skeptic can re-run. The
+ESP32-on-hardware figure remains explicitly **UNMEASURED** — this milestone does
+not pretend a laptop reproduces an Xtensa/WASM3 budget.
+
+## Decision — benches landed
+
+### T1 — wasm-edge `process_frame` budget benches
+
+`v2/crates/wifi-densepose-wasm-edge/benches/process_frame_bench.rs` (criterion,
+`harness = false`, `required-features = ["std"]`). The crate is **excluded from
+the v2 workspace**, so it runs from the crate dir. Benches the M6-audit-named
+heaviest hot paths over a **fixed synthetic CSI frame**, each driven through the
+public `process_frame` after warming the relevant ring/phase buffers so the
+expensive path actually executes:
+
+- `exo_time_crystal::process_frame` — full 256-pt × 128-lag autocorrelation.
+- `exo_ghost_hunter::process_frame` — empty-room periodicity / hidden-breathing.
+- `sec_weapon_detect::process_frame` — per-subcarrier (MAX_SC=32) Welford.
+- `med_seizure_detect::process_frame` — clonic-rhythm path (`#[cfg(feature =
+  "medical-experimental")]`, only built/run with that gate).
+
+The lib's `bench = false` was set so the libtest harness does not intercept
+criterion CLI flags; the `ghost_hunter` bin is already `standalone-bin`-gated and
+not built under `--features std`.
+
+**Measured host medians** (Intel Core Ultra 9 285H, native `--release`):
+`exo_time_crystal` **17.3 µs** · `exo_ghost_hunter` **1.44 µs** ·
+`sec_weapon_detect` **0.42 µs** · `med_seizure_detect` **0.10 µs**.
+
+### T2 — cog inference latency benches
+
+`v2/crates/cog-person-count/benches/infer_bench.rs` and
+`v2/crates/cog-pose-estimation/benches/infer_bench.rs` (criterion,
+`harness = false`). Each loads the **real** shipped weights from the in-repo
+`cog/artifacts/`, asserts the Candle CPU backend (so the stub can never be
+silently benched), warms one forward, then times steady-state
+`InferenceEngine::infer` over a fixed CSI window on `Device::Cpu`.
+
+**Measured host medians:** cog-person-count **305 µs** · cog-pose-estimation
+**305 µs** (steady-state, CPU, real weights).
+
+### T3 — results file
+
+`benchmarks/edge-latency/RESULTS.md`, in the `benchmarks/wiflow-std/RESULTS.md`
+style: each number with its exact reproduce command, the machine, the
+MEASURED-on-host grade, and the honest caveat.
+
+## The honest caveat (recorded, non-negotiable)
+
+1. **Host ≠ ESP32.** The wasm-edge benches run native x86_64, not Xtensa/WASM3.
+   A host median is an **upper bound on algorithm work**, not the ESP32 number;
+   WASM3 interpretation on a ~240 MHz core is 1–2 orders of magnitude slower than
+   native `-O`. A host median under budget does **not** prove the ESP32 meets it.
+   **The ESP32 figure is NOT reproduced here — it needs hardware.**
+2. **Bench ≠ the doc-claimed measurement.** The cogs' manifest cites a
+   **cold-start** number (weight-load included); these benches measure
+   **steady-state** per-frame `infer`. We report both, labelled, and do not
+   conflate them. Empirically, pose steady-state (305 µs host) is ~18× under the
+   5.4 ms cold-start — the expected shape, and exactly why conflating would lie.
+
+## Deferred / still-pending (nothing dropped)
+
+- **ESP32-on-hardware `process_frame` latency** — **PENDING (hardware)**. Needs
+  the `wasm32-unknown-unknown` target built + flashed to an ESP32-S3 and timed
+  under WASM3. The host bench is the algorithm-cost proxy until then.
+- **Per-skill *accuracy*** remains **DATA-GATED** (unchanged from ADR-160) —
+  this ADR measures latency only, never claims detection accuracy.
+
+## Reproduction (MEASURED)
+
+```bash
+# T1 — wasm-edge (workspace-excluded → run from the crate dir)
+cd v2/crates/wifi-densepose-wasm-edge
+cargo bench --features std -- --warm-up-time 1 --measurement-time 2
+cargo bench --features std,medical-experimental -- --warm-up-time 1 --measurement-time 2 med_seizure
+
+# T2 — cogs (workspace members)
+cd v2
+cargo bench -p cog-person-count   --no-default-features --bench infer_bench
+cargo bench -p cog-pose-estimation --no-default-features --bench infer_bench
+
+# existing tests still green (behavior unchanged)
+cargo test -p cog-person-count -p cog-pose-estimation --no-default-features
+```
+
+## Consequences
+
+- ADR-160's deferred *"Criterion benches for `process_frame` budget claims"* line
+  is now **DONE (host)**; the ESP32-on-hardware confirmation is explicitly the
+  one remaining pending item.
+- The cogs now ship committed, reproducible steady-state inference-latency
+  numbers, cleanly distinguished from the manifest's cold-start claim.
+- No runtime behavior changed; no crate republishes. `PROOF.md`'s performance
+  table and `scripts/prove.sh`'s gated section reference the new benches.

+# ADR-164: ADR Corpus Gap Analysis & Remediation Backlog
+
+- **Status:** proposed
+- **Date:** 2026-06-12
+- **Deciders:** ruv
+- **Tags:** governance, meta
+
+## Context
+
+The corpus has grown to **162 ADR entries across 156 distinct files** (ADR-001 through ADR-171; the 5 duplicate-number collisions / 6 displaced files originally noted here were RESOLVED by renumbering the displaced files to ADR-166…171 — see Gap Register G1). It now spans nine subsystems — signal/DSP, NN/training, ESP32 firmware, RuvSense multistatic, RuView desktop, Cognitum cogs, HOMECORE (HA reimplementation), BFLD privacy, and the streaming engine — written over roughly a year by many agent-driven sessions.
+
+Two forces motivate a corpus-wide gap analysis *now*:
+
+1. **The beyond-SOTA / anti-AI-slop sweep (ADR-154–163) just landed.** That sweep is itself a structured retraction layer: each ADR exists *because* an earlier accepted-or-shipped claim was found false (a dead CIR coherence gate, a fake-gradient TTA path, a self-certifying proof, a WebSocket auth bypass, an inflated survivor count). The sweep hardened five subsystems but was narrowly scoped — it never touched the two largest capability gaps (camera-teacher training validation; federation/BFLD privacy chains). A ledger is needed to record what the sweep retracted and what it left open.
+2. **The status field can no longer be trusted as a source of truth.** A five-lens audit (status-distribution, supersession-chains, contradictions, coverage-gaps, data-hardware-gated) found ~24 ADRs mislabeled `Proposed` while their own commit-pinned Implementation-Status notes report them built and tested; 6 ADR numbers collide; 3 files have no Status header at all. An auditor reading headers would conclude "not built" for landed code, and "built/Accepted" for unvalidated capability.
+
+The detailed lens outputs and the full per-ADR census live in `docs/adr/gap-analysis/` (`lens-findings.md`, `census.md`). This ADR is the authoritative summary and remediation backlog.
+
+## Decision
+
+**This ADR is the authoritative gap ledger and remediation backlog for the ADR corpus as of 2026-06-12.** It does not change any subsystem behavior. It records, with cited ADR ids:
+
+- the status/impl distribution and the bookkeeping-drift problem;
+- a prioritized Gap Register with a recommended action per gap;
+- supersession-integrity defects;
+- the contradiction/retraction list (the anti-slop centerpiece);
+- shipped capabilities with no governing ADR;
+- the genuinely open data/hardware-gated backlog.
+
+Until the Gap Register items are worked, **treat the ADR Status header as advisory, not authoritative**, and treat any accuracy number authored before ADR-155 landed as CLAIMED (not MEASURED) until re-derived through the post-155 leak-free validation split.
+
+## Status Distribution
+
+Counts are approximate (`~`) where a status string is non-canonical or dual-valued; the per-ADR breakdown is in `census.md`.
+
+| Status bucket | Count | impl_state | Count |
+|---|---|---|---|
+| Accepted (incl. partial/in-progress/Phase-1 variants) | ~56 | implemented | ~36 |
+| Proposed (incl. conditional/research-only) | ~88 | partial | ~50 |
+| Superseded | 1 (ADR-002) | proposed-only | ~64 |
+| Rejected | 1 (ADR-098) | stale-or-contradicted | 3 (029/030/031) |
+| Missing / no Status header | 3 (ADR-168-proof [was 147], ADR-167-ddd [was 052], ADR-134) | unknown | 5 (034/044/167-ddd/168-proof/…) |
+| Mixed/dual status in one ADR | 3 (115, 149×2, 133) | superseded | 1 (ADR-002) |
+
+**Headline:** ~114 of 162 ADRs (≈70%) are decisions that never fully landed (proposed-only + partial + stale + unknown). The dominant failure mode is **stale Status headers**, not abandoned work.
+
+## Gap Register

+
+## Supersession Integrity
+
+Only **3 formal supersession edges** exist; all three are defective (see G8/G12; full detail in `lens-findings.md` Lens 2):
+
+- **ADR-002 → ADR-016 / ADR-017** is one-directional. ADR-016 never mentions ADR-002 (its References list only 014/015); ADR-017 only *corrects* ADR-002's "fictional crate names" and never says "supersede." The census `supersedes:["ADR-002"]` on 016/017 is **file-unsupported** — the superseded ADR points up at two successors that do not point back.
+- **ADR-002 is an umbrella** whose children 003/007/008/009/010 are still `Proposed`. ADR-016/017 realize only the training/signal/MAT integration points; the RVF-container (003), PQ-crypto (007), Raft (008), WASM-edge-runtime (009), and witness-chains (010) decisions are **neither implemented nor formally superseded**. Marking the parent fully "Superseded" silently buries 5 live-but-abandoned child decisions. Recommended: split ADR-002 to "partially superseded."
+- **ADR-052-tauri → ADR-054** is declared by the predecessor but ADR-054 contains zero references to ADR-052. ADR-054 ("Full Implementation", in progress) is the impl plan *for* 052, not a replacement — likely a mis-modeled edge.
+- **No cycles** detected. The graph is clean structurally; the defect is missing reciprocity and ~7 unrecorded de-facto supersessions (G16).
+
+## Contradictions & Retractions (anti-slop centerpiece)
+
+The four CRITICAL items are the corpus's load-bearing AI-slop admissions — each an accepted-or-shipped surface whose stated accuracy/security/function was provably false until the sweep landed. **Every accuracy number predating ADR-155 should be treated as CLAIMED until re-derived through the post-155 leak-free split.** Source-cited evidence is in `lens-findings.md` Lens 3.
+
+- **[CRITICAL] ADR-155** retracts every prior NN accuracy/TTA/proof claim: real MM-Fi training validated against a *synthetic* val set with stride-1 (~99%) window leakage (§2.2); a *fake gradient* `grad += v*0.01` in the TTA path (§2.3); a *self-certifying* proof that blessed whatever the pipeline emitted and PASSed on 1e-9 float noise (§2.4).
+- **[CRITICAL] ADR-154** proves the ADR-134 CIR coherence gate was **dead in production for every canonical 56-tone frame** (`SubcarrierMismatch`, 0 Ok / 8 mismatch), silently degrading coherence to freq-only. Any "CIR-enhanced coherence/ToF" claim before this fix overstated reality.
+- **[CRITICAL] ADR-079** carries three mutually inconsistent values for its own central metric: proxy PCK@20 = 2.5% (prose) vs 35.3% (baseline table — equal to the *target*) vs 0% upper-body joints; #640 measured 0% on real local data. An Accepted ADR whose headline 10–20x improvement is self-refuting.
+- **[CRITICAL] ADR-161** fixes a HOMECORE WebSocket **auth bypass** (any non-empty token accepted) + reply-theater + no-op automation; **ADR-162** then enforces plugin Ed25519 signature verification, capability isolation, and bounded RunModes — retracting ADR-128/129/130's implied security guarantees.
+- **[HIGH]** ADR-152 self-refutes 1 of 25 claims (ESP WiFi-6 "drop-in" REFUTED 0-3); CLAUDE.md's "WiFlow-STD MEASURED-EQUIVALENT ~96% PCK" contradicts §F1's own gating (97.25% is CLAIMED until measurements (a)–(c) run). ADR-150 retracts the implied cross-subject capability (81.63% in-domain vs ~11.6% leakage-free cross-subject; DANN ~0 gain). ADR-159 ships real models but discloses person-count `training_class1_accuracy = 0.343` and renames "learned multi-person counter" → "presence detector," gutting ADR-103/104's claim.
+- **[MEDIUM]** ADR-163 leaves the ESP32/Xtensa on-hardware latency figure UNMEASURED; ADR-098↔099 partial reversal on midstream; ADR-147 self-retracts Cosmos for OccWorld.
+
+## Coverage Gaps (shipped capability, no/broken governing ADR)
+
+- ~~**CRITICAL — `homecore-recorder`** (SQLite state history + semantic search) cites "ADR-132", which **does not exist**. The durable-state backbone is ungoverned. → write HOMECORE-RECORDER ADR.~~ **RESOLVED in `docs/adr-gap-remediation-1`:** ADR-132 written (`ADR-132-homecore-recorder-history-semantic-search.md`, Status: Accepted — reverse-documented from the shipped crate).
+- ~~**CRITICAL — `homecore-migrate`** (reads untrusted Python-HA `.storage/*.json`) cites "ADR-134", but on-disk ADR-134 is CIR. A data-integrity-sensitive importer governed by a phantom identity. → resolve 134 collision + write HOMECORE-MIGRATE ADR (trust boundary).~~ **RESOLVED in `docs/adr-gap-remediation-1`:** ADR-165 written (`ADR-165-homecore-migrate-from-home-assistant.md`, Status: Accepted — P1 scaffold); crate's `ADR-134` refs repointed → ADR-165; on-disk ADR-134 (CIR) left intact. ADR-126's series-map row (which labels the *role* "ADR-134 HOMECORE-MIGRATE") is owner-gated and unchanged.
+- **HIGH — `wifi-densepose-engine`** composes ADR-135..146 onto the live 20 Hz path but **no ADR governs the integrator contract** (ordering, back-pressure, "one pipeline cycle" boundary).
+- **MEDIUM — `wasm-edge`** (~70 skills) governed only by remediation ADRs 160/163 — no creation/taxonomy/ABI ADR. **`occworld-candle`** is a Rust-native backend swap ADR-147 explicitly deferred. **`pointcloud`** has only a viewer-deploy ADR (094), no data-format contract.
+- **MEDIUM — workspace topology:** ~38 crates exist; the CLAUDE.md 15-crate table and 12-step publishing order are stale, and no ADR governs crate-graph/publish boundaries at this scale.
+- Verified-governed (scoped out): worldmodel→147, worldgraph→139, cog-*→101/103/116, ruview-swarm→148, nvsim→089/092, bfld→118-123/141, calibration→151, homecore-hap→125, geo→044, desktop→052/054.
+
+## Open / Gated Backlog (genuinely unresolved, honestly labeled)
+
+The ADR-154–163 sweep was narrowly scoped. The two largest **capability** gaps it did not touch:
+
+- **CRITICAL — Camera-teacher training validation (ADR-079 / 072 / 150).** P7–P9 Pending; blocker is a real synchronized camera+ESP32 paired-capture session + GPU training on the fleet (ruvultra RTX 5080). Cross-subject collapse (11.6%) is data-gated on a heterogeneous multi-subject CSI dataset, per ADR-150 §F3 / ADR-152 F3 (the lever is *more data*, not capacity). Accepted-on-paper, not proven.
+- **HIGH — Federation + BFLD privacy chains (ADR-105–109, 118–125).** All Proposed-only, ACs unchecked. Blockers: KIT BFId dataset (121), Pi5/Nexmon CBFR capture hardware (123 — ESP32 structurally cannot sniff CBFR), Soul-Signature + cog-ha-matter (122/125). The privacy control *plane* (ADR-141) is built; the *capture/scoring* chain it gates is not.
+- ~~**HIGH — Sensing-server security (ADR-080).** Distinct from the HOMECORE boundary the sweep fixed; XFF bypass / stack-trace leakage / JWT-in-URL remain open.~~ **RESOLVED (2026-06-13, G11):** verified against the current Rust sensing-server — stack-trace leakage was the one live finding (fixed via `error_response` generic bodies); XFF bypass and JWT-in-URL were verified absent and regression-pinned. See ADR-080 P0 §1–3.
+- **MEDIUM — gold-standard deferrals (model to follow):** ADR-163 (ESP32 on-hardware latency UNMEASURED), ADR-160 (medical/affect/weapon NOT validated, relabelled), ADR-158 (RF-through-rubble + learned counter DATA-GATED). Code is real, the claim is withheld pending absent hardware/labelled data — labels are honest.
+- **MEDIUM — purely hardware/data-gated Proposed decisions (no overreach):** ADR-023, 027, 042, 063/064, 065/066, 070, 073/078, 083, 086, 091, 103, 110 (HE-CSI needs ESP-IDF ≥5.5), 113, 114, 134/135, 143-v2, 144. *needs verification* where flags rely on downstream prose rather than direct file inspection.
+
+## Consequences
+
+**Positive.** One authoritative ledger replaces scattered, drifting status fields. The anti-slop retractions are recorded in a citable place, so the "AI slop" accusation is met with a structured admission + fix-trail rather than denial. The Gap Register is a concrete, severity-ordered work queue. Batch-fixing G5 (10 streaming-engine headers) and G1/G2 (numbering + missing headers) is high-ROI and unblocks ADR tooling.
+
+**Negative.** This ADR is a snapshot; it goes stale the moment the next ADR lands. Counts marked `~` are approximate and a few impl_state values are *needs verification* (downstream-prose-derived, not file-confirmed). Acting on the register (renumbering, status flips, supersession edits) touches ~30 files and risks transient cross-reference breakage if not done atomically.
+
+**Neutral.** No subsystem behavior changes. Renumbering decisions (which of the colliding files keeps each number) are deferred to the follow-up remediation PR — this ADR records the collision, not the resolution. Whether to close abandoned chains as `Rejected` vs `Deferred` is a judgment call left to the deciders per chain.

+# ADR-165: HOMECORE-MIGRATE — Migration Tooling from Python Home Assistant

+> renumber is owner-gated and left for the follow-up. This ADR reverse-documents the shipped
+> P1 scaffold; it introduces no new design.
+
+---
+
+## 1. Context
+
+ADR-126 decided to reimplement Home Assistant (HA) natively in Rust. A user adopting
+HOMECORE has an existing HA install whose configuration lives in two places on disk:
+
+- `.storage/*.json` — versioned JSON envelopes (`{ version, minor_version, data }`) holding
+  the entity registry, device registry, and config entries;
+- top-level YAML — `secrets.yaml`, `automations.yaml`.
+
+To migrate, HOMECORE must read this foreign, **untrusted** on-disk state. 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. Decision
+
+Ship `homecore-migrate` as a CLI + library that reads an existing HA filesystem and imports
+its configuration into HOMECORE. P1 is a **scaffold**: it parses and inspects everything and
+converts the entity registry; full conversion of the remaining artifacts is deferred to P2.
+
+### 2.1 Storage reader + versioned format gate (P1, shipped)
+
+- `HaStorageDir` / `HaStorageEnvelope` read HA's `.storage/` directory; `read_envelope(path)`
+  deserializes a `.storage/*.json` envelope (`src/storage.rs`).
+- Versioned parsers live under `storage_format::v<N>` (e.g. `v13` for the entity registry)
+  (`src/storage_format/`).
+- **Schema-version validation is the load-bearing safety rule (§6 Q5 of this ADR):** an
+  unknown `minor_version` is a **hard error** (`MigrateError::UnsupportedSchemaVersion`),
+  never a silent best-effort parse. Better to refuse than to corrupt.
+
+### 2.2 Per-artifact parsers (P1, shipped)
+
+- `entity_registry::load()` — `core.entity_registry` → `Vec<homecore::EntityEntry>`
+  (ready for import).
+- `device_registry::load()` — `core.device_registry` → `Vec<DeviceImport>` (P1 diagnostic;
+  full conversion P2).
+- `config_entries::load()` — `core.config_entries` → domain counts + integration names
+  (the format is undocumented per §6 Q5; treated diagnostically).
+- `secrets::load_secrets()` — `secrets.yaml` → `HashMap<String, String>` (resolution P2).
+- `automations::load()` — `automations.yaml` → count + ID/alias list (conversion P2).
+
+### 2.3 CLI (P1, shipped)
+
+- `homecore-migrate inspect <ha-dir>` previews what will be migrated (entity/device/config
+  counts, redacted secret/automation lists) (`src/cli.rs`, `src/main.rs`).
+- `import-entities` and `export-for-sidecar` are declared but their full behaviour is P2.
+
+### 2.4 Structured errors (P1, shipped)
+
+- `MigrateError` carries context (`path`, line/field) for I/O, JSON, YAML, missing-field,
+  unsupported-schema-version, and entity-id parse failures (`src/lib.rs`).
+- **Secret-leak hardening (security review, 2026-06).** `secrets.yaml` parse failures must
+  NOT use the generic `MigrateError::YamlParse { source }` variant: `serde_yaml`'s message
+  for a typed-tag coercion error (e.g. `port: !!int <value>`) embeds the offending scalar
+  verbatim (`invalid value: string "<the-secret-value>"`), and that error propagates through
+  the `InspectSecrets` CLI path to stderr — leaking a secret value despite the CLI's
+  deliberate `<redacted>` design. `read_secrets` now maps such failures to a dedicated
+  redacting variant `MigrateError::SecretsParse { path, line, column }` that carries only the
+  file path and a coarse location (`serde_yaml::Error::location()`), never the scalar content.
+  Pinned by `secrets::tests::malformed_secrets_error_never_contains_secret_value` (asserts the
+  rendered error **and its full `#[source]` chain** never contain the secret value).
+  **Review dimensions confirmed clean with evidence:** source is never mutated (no
+  `fs::write`/`remove`/`create` anywhere — P1 reads source, writes nothing); paths are
+  user-supplied dirs joined with fixed filenames (no `..`/absolute traversal beyond the
+  user's own privileges); malformed/typed/truncated `.storage` JSON and YAML **error, never
+  panic** (every production `unwrap`/`expect` is test-only); unknown schema `minor_version`
+  hard-errors fail-closed; no SQL/shell/path injection surface (the tool emits diagnostics
+  only, persists nothing in P1).
+
+### 2.5 Deferred to P2+ (NOT built — honestly labelled)
+
+- Convert `config_entries` → HOMECORE plugin manifests.
+- Convert `automations.yaml` → `homecore-automation` YAML.
+- Side-by-side runtime mode (requires `homecore-recorder`, ADR-132; behind the `recorder`
+  Cargo feature, currently a no-op stub).
+- `!secret` reference resolution in non-secrets YAML files.
+
+### 2.6 Test evidence (as shipped)
+
+- 21 tests (`cargo test -p homecore-migrate`) — 19 as originally shipped plus 2 added by the
+  2026-06 security review (`secrets::tests::malformed_secrets_error_never_contains_secret_value`,
+  `malformed_secrets_error_reports_location`).
+
+## 3. Consequences
+
+**Positive.**
+
+- The trust boundary is explicit: unknown HA schema versions are rejected, not guessed, so a
+  schema drift fails loudly instead of corrupting an imported home.
+- Reusing HA's own `.storage` and YAML formats means no intermediate export step; the tool
+  reads a live HA install directly.
+- P1 `inspect` gives users a no-risk dry run before any write.
+
+**Negative / honest limits.**
+
+- P1 is a **scaffold**: only the entity registry is conversion-ready. Device registry,
+  config-entry→plugin, automation, and secret-resolution conversions are P2 and **not yet
+  built** — the Status field and crate docs say so.
+- The side-by-side recorder export depends on ADR-132 and is currently a feature-gated
+  no-op.
+- Performance figures in the README (envelope parse < 5 ms, 1 000-entity load < 50 ms) are
+  estimates, **needs verification** with a benchmark.
+
+**Neutral.**
+
+- This resolves only the *identity* of the migrate decision (134→165). The broader 6-way
+  duplicate-number cleanup (incl. ADR-126's series-map registry row) is owner-gated.

+# ADR-169: adam-mode — light theme toggle for the three.js realtime demo
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-06-02 |
+| **Deciders** | ruv |

+| **Scope** | `examples/three.js/demos/05-skinned-realtime.html` (primary), demos 01–04 (follow-on) |

+| **Tracking issue** | none yet |
+
+---
+
+## 1. Context
+
+`examples/three.js/demos/05-skinned-realtime.html` (build stamp `2026-05-15-fps-tune`) is the live MediaPipe → Mixamo retargeting + ESP32 CSI overlay demo. It currently ships a single, opinionated **dark theme**:
+
+- Body `--bg: #050507` (near-black), `--text: #d8c69a` (warm beige).
+- Amber accents (`--amber: #ffb840`, `--amber-hot: #ffe09f`) on panels and controls.
+- Two full-screen overlays: a radial-vignette `.overlay-frame` and a 50%-opacity CRT-style `.scanlines` layer.
+- Three.js scene matches: `scene.background = new THREE.Color(0x050507)` and `scene.fog = new THREE.FogExp2(0x050507, 0.06)` (lines 269–270).
+
+The dark/amber CRT aesthetic is intentional for screen-recording and "command-centre" feel, but it has real failure modes:
+
+1. **Daylight visibility** — Demoing the live capture on a laptop in a sunlit room is unreadable; the dark background absorbs ambient glare and the amber-on-dark contrast disappears.
+2. **Recording for embedded/print contexts** — When the demo's screen is captured for documentation, blog posts, or HA blueprints, the dark theme bleeds into surrounding white content and looks heavy.
+3. **Accessibility** — A subset of users with light-sensitive retinas (the inverse of typical photophobia) report the high amber-on-near-black combination strains them; high-contrast light themes are easier.
+4. **Operator pairing with a light-mode IDE** — Many operators run a light-mode browser alongside a dark-mode IDE and want the demo to match the browser, not the IDE.
+
+A toggle is the right answer because none of these reasons are universal — some sessions and some users want each mode.
+
+### 1.1 What this ADR is *not*
+
+- Not a redesign. The amber accent stays; only the surface colours and overlays swap. The information density, panel layout, and three.js scene geometry are unchanged.
+- Not a multi-theme system. We add exactly two themes: the existing dark (default, unnamed) and **adam-mode** (light). Future themes would need a new ADR.
+- Not a backend / data-model change. Pure presentation.
+- Not yet propagated to demos 01–04. Those follow-on after adam-mode lands on demo 05 and is validated.
+
+## 2. Decision
+
+Add a **client-side theme toggle** to `05-skinned-realtime.html` that switches between the existing dark theme and a new light theme called **adam-mode**, driven by a `data-theme="adam"` attribute on `<body>` plus a sibling `:root[data-theme="adam"]` CSS block that re-defines the existing custom properties. A new toggle button in the existing `#helpers` panel switches between modes and persists the choice in `localStorage` under the key `ruview.theme`.
+
+### 2.1 CSS — the colour swap
+
+Add immediately after the existing `:root { ... }` block in `<style>`:
+
+```css
+:root[data-theme="adam"] {
+    --bg: #f6f2ea;
+    --bg-panel: rgba(252, 250, 246, 0.92);
+    --amber: #b8741a;        /* deeper amber, readable on cream */
+    --amber-hot: #8a5612;    /* deepest amber for emphasis text */
+    --cyan: #1a6f8a;         /* slate cyan */
+    --magenta: #a8348a;      /* slate magenta */
+    --text: #2a241c;         /* near-black warm */
+    --text-mute: #7a6f5d;    /* warm grey */
+    --green: #1f7a32;        /* forest green */
+    --red: #b03a1a;          /* burnt sienna */
+    --border: rgba(184, 116, 26, 0.28);
+}
+```
+
+Every existing element already reads from these custom properties, so the swap is automatic for panels, text, borders, and bar fills. No per-element CSS rewrites required.
+
+### 2.2 Overlay handling
+
+The vignette and scanlines are dark-theme aesthetics. In adam-mode they would muddy the cream background. Two new rules:
+
+```css
+:root[data-theme="adam"] .overlay-frame {
+    background:
+        radial-gradient(ellipse at center, transparent 70%, rgba(184,116,26,0.10) 100%),
+        linear-gradient(180deg, rgba(184,116,26,0.06) 0%, transparent 18%, transparent 82%, rgba(184,116,26,0.08) 100%);
+}
+:root[data-theme="adam"] .scanlines {
+    opacity: 0.15;
+    mix-blend-mode: multiply;
+}
+```
+
+The vignette is preserved but inverted in colour and lightened; scanlines drop to 15 % opacity and switch from `overlay` to `multiply` blend so they read as faint paper texture rather than CRT lines.
+
+### 2.3 Three.js scene reactivity
+
+Two scene colours are hard-coded at construction (lines 269–270). Replace them with a function call that reads the current theme:
+
+```js
+function themeSceneColors(theme) {
+    return theme === 'adam'
+        ? { bg: 0xf6f2ea, fogDensity: 0.025 }
+        : { bg: 0x050507, fogDensity: 0.06 };
+}
+function applySceneTheme(theme) {
+    const c = themeSceneColors(theme);
+    scene.background = new THREE.Color(c.bg);
+    scene.fog = new THREE.FogExp2(c.bg, c.fogDensity);
+    renderer.setClearColor(c.bg, 1.0);
+}
+```
+
+Called once after `renderer` is constructed, then again from the toggle handler.
+
+`scene.fog` density drops in adam-mode because exponential fog on a light background reads as "haze" much more strongly than on dark — 0.06 → 0.025 keeps the falloff visible without losing the figure into the background.
+
+### 2.4 UI toggle
+
+Add to the `#helpers` panel (top of its labels list):
+
+```html
+<label class="theme-toggle">
+    <input type="checkbox" id="adam-mode-toggle">
+    <span>adam-mode (light)</span>
+    <span class="swatch" style="background: var(--amber)"></span>
+</label>
+```
+
+Handler:
+
+```js
+const THEME_KEY = 'ruview.theme';
+const root = document.documentElement;
+const toggle = document.getElementById('adam-mode-toggle');
+
+function applyTheme(theme) {
+    if (theme === 'adam') {
+        root.setAttribute('data-theme', 'adam');
+        toggle.checked = true;
+    } else {
+        root.removeAttribute('data-theme');
+        toggle.checked = false;
+    }
+    applySceneTheme(theme);
+    try { localStorage.setItem(THEME_KEY, theme); } catch (_) {}
+}
+
+const initialTheme = (() => {
+    try { return localStorage.getItem(THEME_KEY) || 'dark'; }
+    catch (_) { return 'dark'; }
+})();
+applyTheme(initialTheme);
+
+toggle.addEventListener('change', e => {
+    applyTheme(e.target.checked ? 'adam' : 'dark');
+});
+```
+
+### 2.5 Why "adam-mode" as the codename
+
+The user picked the name. It is a project-specific brand — distinct from the generic "light mode" terminology that other modes (`--theme=high-contrast`, `--theme=print`) may eventually need. Keeping a codename makes the toggle searchable in the codebase, the localStorage key portable across the demo set, and avoids ambiguity if dark itself is later renamed.
+
+The string `"adam"` is the only literal value the `data-theme` attribute and the `localStorage` key ever take. `"dark"` is the implicit default (no attribute, no stored value).
+
+### 2.6 Rejected alternatives
+
+| Alternative | Rejected because |
+|---|---|
+| Use `prefers-color-scheme: light` only, no toggle | Operators frequently want the opposite of their OS preference for screen-recording or daylight desk use. Auto-only frustrates the actual use case. |
+| Ship two separate HTML files (`05-…-dark.html`, `05-…-light.html`) | Doubles maintenance for every future demo edit. No path to per-session toggle. |
+| Build a full multi-theme system with a runtime registry | Premature. Two themes don't need a registry; the `data-theme="adam"` attribute is the registry. |
+| Use Tailwind / DaisyUI / a CSS framework | Demos are intentionally stand-alone single-file HTML for portability. No build step exists; adding one for theming is wrong shape. |
+| Adopt the cognitum-v0 / HOMECORE design tokens (`--hc-*` from `examples/frontend/`) | That design system is dark-only by intent (ADR-131). adam-mode is the light counterpart needed in *demo* contexts, not HA dashboard contexts. |
+| Make adam-mode the default | Breaks the dark-aesthetic recording context this demo was originally built for. Default stays dark; toggle stays opt-in. |
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- Demo is usable in daylight, in printed documentation, on light-mode browsers, and by users who find the dark-amber combination fatiguing.
+- Toggle persists across reloads via `localStorage` — set once, sticks.
+- No structural change to information density, panel layout, or three.js scene geometry. Operators familiar with the dark theme can switch and still find every readout in the same place.
+- Implementation is contained — a single `<style>` block addition, a single button, a ~25-line JS handler, and a swap of two scene-construction lines.
+
+### 3.2 Negative
+
+- Two themes to maintain. Any future colour change requires updating both `:root` blocks. Mitigated by keeping the existing custom-property names — adam-mode's values are the only edits.
+- The vignette + scanlines lose some of the CRT charm in adam-mode. Tradeoff accepted by design.
+- One additional `localStorage` slot consumed per origin (`ruview.theme`).
+- The amber accent in adam-mode (`#b8741a`) is visibly different from the dark-mode amber (`#ffb840`) — they share the same CSS variable name but a screenshot from each mode is not pixel-comparable. This is the correct call for accessibility (the bright amber is unreadable on cream) but does mean side-by-side comparisons need both screenshots labelled.
+
+### 3.3 Risks
+
+| Risk | Likelihood | Mitigation |
+|---|---|---|
+| Future demo edits update one `:root` block and forget the other | Medium | A lint script in `scripts/` could grep both blocks for matching key sets; documented as P2 follow-up. |
+| `localStorage` blocked by privacy settings | Low | All accesses are wrapped in try/catch; falls back to dark. |
+| Three.js fog density of 0.025 still washes out the model on adam-mode | Low | Empirically tuned during implementation; if it does, drop to 0.015 or remove fog entirely in adam-mode. |
+| User on a high-DPI display sees scanlines as visible paper texture even at 15 % opacity | Low | If reported, drop to 8 % or hide scanlines entirely in adam-mode. |
+
+## 4. Implementation plan
+
+Tiny scope — single file. No swarm needed.
+
+1. Add `:root[data-theme="adam"]` CSS block and the two overlay overrides.
+2. Refactor scene background + fog into the two helper functions `themeSceneColors()` and `applySceneTheme()`.
+3. Add `<label>` markup and handler script.
+4. Verify in a browser at http://127.0.0.1:8765/examples/three.js/demos/05-skinned-realtime.html — toggle on, reload, confirm adam-mode persists; toggle off, reload, confirm dark persists.
+5. Smoke-screenshot both modes; commit.
+
+Acceptance criteria:
+
+- Toggle checkbox visible in `#helpers` panel.
+- Clicking the toggle swaps colours within one frame.
+- Reload preserves last choice.
+- Three.js scene background follows the toggle (no dark frame visible behind a light HUD or vice-versa).
+- Existing dark-theme appearance is byte-identical when toggle is off.
+
+## 5. Test plan
+
+- Manual visual check in two themes (no automated visual regression — demos aren't in the CI test loop today).
+- `view-source` confirms the new CSS block, the toggle markup, and the handler are present.
+- DevTools `localStorage` shows `ruview.theme` after a toggle.
+- Three.js inspector (or a `console.log(scene.background.getHexString())`) confirms scene colour swap.
+
+## 6. Follow-on work (out of scope for this ADR)
+
+- Roll adam-mode into demos 01–04. Each demo has its own `<style>` block; the same `data-theme="adam"` selector and the same JS handler can be copied.
+- Honor `prefers-color-scheme: light` on first load *if* `localStorage` has no stored choice. Trivial three-line addition.
+- Add a high-contrast theme for accessibility (separate ADR).
+- Lint script that asserts both `:root` blocks declare the same custom-property names.

+# ADR-170: yoga-mode — pose detection, classification, and scoring for the three.js realtime demo
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-06-02 |
+| **Deciders** | ruv |
+| **Codename** | **yoga-mode** |
+| **Scope** | `examples/three.js/demos/05-skinned-realtime.html` (primary); new `examples/three.js/demos/06-yoga-mode.html` (secondary, slimmed-down) |
+| **Relates to** | ADR-169 (adam-mode light theme), ADR-019 (sensing-only UI), ADR-035 (live sensing UI accuracy) |
+| **Tracking issue** | none yet |
+
+---
+
+## 1. Context
+
+`examples/three.js/demos/05-skinned-realtime.html` already runs the full MediaPipe Pose Heavy pipeline at ~30 Hz: 33 BlazePose landmarks flow through a one-euro-filter bank into joint-angle extraction and then into a Mixamo X Bot IK retarget. The `#pose-panel` HUD shows landmark count, visibility, and pose FPS. The `#helpers` panel (ADR-097) has adam-mode (ADR-169) and eight visualisation toggles.
+
+This infrastructure is complete. Every frame, per-joint angles are already computable from the existing `liveKp` world-space landmark array. What does not yet exist is any layer that interprets those angles as a known yoga pose, scores the user's alignment against a target shape, and guides the user through a structured sequence.
+
+### 1.1 Why yoga-mode in this demo
+
+Three concrete use-cases drive this:
+
+1. **Developer self-test for the retargeting pipeline.** Cycling through a Sun Salutation A is a systematic, reproducible way to exercise every major joint (shoulder, elbow, hip, knee, spine). A pose-scoring overlay makes regression immediately visible — if a code change breaks elbow retargeting, the yoga classifier will output a depressed alignment score on Chaturanga even before a visual inspection.
+
+2. **Public demonstration value.** The demo is served at `http://127.0.0.1:8765/examples/three.js/demos/05-skinned-realtime.html` and shown to evaluators. A guided instructional mode that scores real-time body alignment against Tadasana or Downward Dog is immediately intelligible to a non-technical audience in a way that raw CSI amplitude bars are not.
+
+3. **Future bridge to the Rust host.** The Rust-side `wifi-densepose-signal/src/ruvsense/pose_tracker.rs` maintains a 17-keypoint Kalman tracker in COCO convention. yoga-mode in the demo operates on the 33-landmark MediaPipe convention. These are not the same: MediaPipe indices 0–32 (BlazePose) map non-trivially to COCO 0–16. Deciding the mapping now — even in a pure-JS context — canonicalises it for the eventual Rust integration.
+
+### 1.2 What this ADR is *not*
+
+- Not a backend service. No WebSocket endpoint, no session record, no cloud upload. Pure client-side HTML.
+- Not a fitness-app competitor. The scope is Sun Salutation A (8 poses). The full 84-asana classical corpus is out of scope.
+- Not an integration with the Rust `pose_tracker.rs`. That bridge is documented here as a future consequence, not an immediate deliverable.
+- Not a redesign of demo 05. Panel layout, three.js scene geometry, and the CSI overlay are unchanged.
+- Not a new design system. yoga-mode inherits every existing CSS custom property.
+
+### 1.3 COCO-17 ↔ BlazePose-33 mapping note
+
+The Rust tracker uses COCO 17-keypoint indices (0=nose, 5=left-shoulder, 6=right-shoulder, 7=left-elbow, 8=right-elbow, 9=left-wrist, 10=right-wrist, 11=left-hip, 12=right-hip, 13=left-knee, 14=right-knee, 15=left-ankle, 16=right-ankle). MediaPipe BlazePose-33 uses a different, denser scheme where shoulders are at 11–12, elbows at 13–14, wrists at 15–16, hips at 23–24, knees at 25–26, ankles at 27–28.
+
+The mapping for the 13 joints used in yoga-mode angle computation is:
+
+| Joint role | COCO idx | BlazePose idx |
+|---|---|---|
+| nose | 0 | 0 |
+| left shoulder | 5 | 11 |
+| right shoulder | 6 | 12 |
+| left elbow | 7 | 13 |
+| right elbow | 8 | 14 |
+| left wrist | 9 | 15 |
+| right wrist | 10 | 16 |
+| left hip | 11 | 23 |
+| right hip | 12 | 24 |
+| left knee | 13 | 25 |
+| right knee | 14 | 26 |
+| left ankle | 15 | 27 |
+| right ankle | 16 | 28 |
+
+When the Rust host integration is implemented, the joint-angle features extracted by yoga-mode in JS and by `pose_tracker.rs` in Rust will be computed from the same physical joints via this table. No translation layer is needed at runtime — yoga-mode always uses BlazePose indices; `pose_tracker.rs` always uses COCO indices.
+
+### 1.4 Biomechanical basis for joint-angle targets
+
+The joint-angle targets in this ADR are grounded in peer-reviewed measurements. Perez-Testor et al. (2019, PMC6521759) captured 10 trained practitioners performing Surya Namaskar A on a 12-camera Vicon system at 100 Hz, reporting sagittal-plane joint angles at each pose transition. Key ranges: elbow 22°–116°, hip 15° extension to 134° flexion, knee 3° hyperextension to 140° flexion, spine 44° extension to 58° flexion, shoulder 56°–183°. These empirical ranges set the upper and lower bounds for the tolerance bands in this ADR's pose templates. Where Perez-Testor does not report a joint (e.g. wrist flexion for Chaturanga arm angle), the Iyengar geometry — "elbows at 90° bent close to the body" — supplies the target value. A 2023 PMC yoga-pose review (PMC10280249) confirming angle-heuristic approaches as the most reliable real-time classification method validates the algorithmic choice.
+
+---
+
+## 2. Decision
+
+### 2.1 Pose taxonomy — Sun Salutation A, 8 poses
+
+Sun Salutation A is chosen for the first ship. It satisfies three criteria simultaneously: the poses are geometrically distinct from each other (no two share the same joint-angle signature), they form a complete bilateral sequence (both left and right sides are exercised), and they are among the best-documented asanas in the biomechanics literature. The Sanskrit and English names are unambiguous in the Ashtanga tradition.
+
+The 8 poses in sequence order with their one-line joint-angle signatures:
+
+| Stage | Sanskrit | English | Joint-angle signature |
+|---|---|---|---|
+| 1 | Tāḍāsana | Mountain Pose | All limbs extended: knees 180°, hips 180°, elbows 180°, spine vertical |
+| 2 | Ūrdhva Hastāsana | Upward Salute | Arms overhead: shoulders ~180° abducted, elbows 180°, torso elongated |
+| 3 | Uttānāsana | Standing Forward Fold | Hips ~0–30° (full fold), knees 180°, elbows relaxed, spine flexed |
+| 4 | Ardha Uttānāsana | Half Lift / Flat-Back | Hips ~90° (parallel torso), knees 180°, spine neutral (horizontal) |
+| 5 | Catvāri (Chaturanga Daṇḍāsana) | Four-Limbed Staff | Hips 180° (plank line), elbows ~90°, shoulders depressed, body horizontal |
+| 6 | Ūrdhva Mukha Śvānāsana | Upward-Facing Dog | Hips extended ~160°+, shoulders over wrists, spine extended, knees off floor |
+| 7 | Adho Mukha Śvānāsana | Downward-Facing Dog | Hips ~80–110° (inverted V), knees 180°, shoulders ~180° (arms overhead), spine long |
+| 8 | Uttānāsana | Standing Forward Fold (return) | Same as stage 3 — mirrors the descent; re-classified as stage 8 for sequence tracking |
+
+"All 84 classical asanas" is explicitly rejected. Even the 26-pose Bikram set is rejected — the goal is a complete, self-contained instructional sequence for a 2–3 minute demo session, not exhaustive coverage. Eight poses are the minimum for a meaningful sequence narrative and the maximum that fits a single UI strip without horizontal scrolling on a 1080p screen.
+
+### 2.2 Detection algorithm — joint-angle threshold matching with weighted scoring
+
+**Chosen: joint-angle threshold matching.** For each frame, compute the angle at 6–10 named joints (one angle per joint, defined as the interior angle at the vertex formed by three landmarks). Compare each computed angle to the per-pose target. Score by weighted absolute deviation. Classify the argmax.
+
+**Why not the alternatives:**
+
+| Alternative | Verdict | Reason |
+|---|---|---|
+| Skeleton-as-vector cosine similarity | Rejected | Position-sensitive: a person standing 2 m from the camera vs. 1 m produces different vectors. Joint angles are translation- and scale-invariant by construction. |
+| Small MLP trained on a labelled dataset | Rejected | No labelled dataset exists in this codebase. Training a reliable MLP for 8 poses would require hundreds of labelled examples per class, a train/test split, and a model serialization format — none of which belongs in a single-file demo HTML. Joint-angle matching achieves the same discrimination for 8 geometrically distinct poses with zero training data. |
+| MediaPipe Tasks PoseClassifier (EfficientNet-based) | Rejected | Requires loading a separate `.task` bundle (~4 MB), adds a network dependency to the demo's offline-capable design, and uses a black-box embedding — undebuggable when a pose is misclassified. Threshold matching is fully inspectable in DevTools. |
+| DTW template matching on full landmark sequences | Rejected | Appropriate for gesture recognition over time (ADR-014's `gesture.rs`), not static pose classification. Sun Salutation transitions are slow (2–5 seconds per pose); per-frame angle scoring is sufficient. |
+
+**Joint angle computation.** For three landmark positions A (proximal), B (vertex), C (distal), the interior angle at B is:
+
+```
+angle_B = arccos( dot(A-B, C-B) / (|A-B| * |C-B|) )   in degrees
+```
+
+This is computed in world-space from the existing `liveKp` THREE.Vector3 array. The computation is purely arithmetic — no matrix inversion, no DFT. At 30 Hz on any modern laptop it is unmeasurably fast relative to the MediaPipe inference cost.
+
+**Named joints used in yoga-mode.** Joint names, their three-landmark triplets (proximal-vertex-distal), and the BlazePose indices:
+
+| Joint name | Triplet (P-V-D) | Indices |
+|---|---|---|
+| `left_elbow` | shoulder→elbow→wrist | 11→13→15 |
+| `right_elbow` | shoulder→elbow→wrist | 12→14→16 |
+| `left_knee` | hip→knee→ankle | 23→25→27 |
+| `right_knee` | hip→knee→ankle | 24→26→28 |
+| `left_hip` | shoulder→hip→knee | 11→23→25 |
+| `right_hip` | shoulder→hip→knee | 12→24→26 |
+| `left_shoulder` | hip→shoulder→elbow | 23→11→13 |
+| `right_shoulder` | hip→shoulder→elbow | 24→12→14 |
+| `torso_lean` | hip-midpoint→shoulder-midpoint→vertical | synthetic |
+
+`torso_lean` is the angle between the hip-to-shoulder axis and the world vertical (Y axis). It distinguishes standing-upright (≈0°) from folded-forward (≈90°) from plank-horizontal (≈90° in a different axis pattern). In practice, it is implemented as `acos(dot(hipToShoulder.normalize(), UP_VECTOR))` where `UP_VECTOR = (0,1,0)`.
+
+### 2.3 Pose template format — inline JSON, single-file portable
+
+Templates live as a JS object literal inside the `<script>` block of the demo file. A sibling `poses.json` would break the single-file portability that makes demos easy to share and locally serve. The inline approach imposes no additional HTTP request and no CORS constraint.
+
+**Schema** (one template per pose):
+
+```js
+{
+  id: "tadasana",              // machine-readable ID, localStorage key fragment
+  name_en: "Mountain Pose",    // English common name
+  name_sa: "Tāḍāsana",        // Sanskrit with diacritics
+  stage: 1,                    // position in the Sun Salutation A sequence (1-8)
+  joint_targets: {
+    left_elbow:    { angle_deg: 180, tolerance_deg: 15, weight: 0.5 },
+    right_elbow:   { angle_deg: 180, tolerance_deg: 15, weight: 0.5 },
+    left_knee:     { angle_deg: 180, tolerance_deg: 10, weight: 1.0 },
+    right_knee:    { angle_deg: 180, tolerance_deg: 10, weight: 1.0 },
+    left_hip:      { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    right_hip:     { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    torso_lean:    { angle_deg:   0, tolerance_deg: 12, weight: 1.2 },
+  },
+  instruction: "Stand tall. Feet hip-width, weight even. Arms relaxed at your sides. Lengthen through the crown.",
+  min_hold_s: 3,               // seconds the pose must be held to count as completed
+}
+```
+
+**Schema decisions:**
+
+- `tolerance_deg` is the half-width of the pass band. An angle within `[target - tolerance, target + tolerance]` contributes full score for that joint. Beyond the tolerance band the score degrades linearly to zero at `target ± (tolerance * 3)`, then clamps to zero. This linear-outside-band behaviour prevents cliff edges where being 16° off scores identically to 90° off.
+
+- `weight` carries the importance signal. High-weight joints (torso_lean 1.2, knees 1.0) dominate the aggregate score. Low-weight joints (elbows 0.5 in Tadasana, where arm position is relaxed) have less influence. A weight of 0 would mask a joint entirely — used when the joint is not visible (see §2.7 graceful degradation).
+
+- `min_hold_s` is per-template. Tadasana and Uttanasana are grounding poses that benefit from a 3-second hold. Chaturanga is a strength pose where 2 seconds is already challenging. The value lives in the template, not as a global constant, so future operators can tune it per pose without touching logic.
+
+- There is no `max_hold_s`. Holding a pose longer than `min_hold_s` does not penalise the score.
+
+**Why `tolerance_deg` over explicit pass/fail thresholds.** A binary pass/fail at a hard threshold creates a jarring UX: the alignment bar slams between 0% and 100% at a single degree of motion. Linear-outside-band degradation provides smooth visual feedback that guides the user toward the target incrementally.
+
+### 2.4 Scoring formula
+
+Per-frame alignment score for pose *p*, given measured angle `θ_j` at joint *j*:
+
+```
+delta_j = |θ_j  −  target_j.angle_deg|
+
+band_score_j =
+    1.0                                           if delta_j ≤ tolerance_j
+    1.0 − (delta_j − tolerance_j) / (2 * tolerance_j)   if delta_j ≤ 3 * tolerance_j
+    0.0                                           otherwise
+
+raw_score_p = Σ_j ( weight_j * band_score_j ) / Σ_j ( weight_j )
+
+alignment_score_p = clamp(raw_score_p, 0.0, 1.0)
+```
+
+`alignment_score_p` is a value in [0, 1]. Displayed in the `#yoga-panel` as an integer percentage (0–100) with one decimal place for the progress ring to animate smoothly.
+
+**Hold-time component.** The classifier reports a pose as *completed* when two conditions are simultaneously true:
+1. The pose has been the argmax classifier output for a contiguous streak of `K = 6` frames (see §2.5).
+2. Within that streak, the alignment score has remained above 0.6 (60%) for at least `min_hold_s` seconds.
+
+Completion is a one-shot event per pose per sequence pass. It fires once, advances the sequence indicator, and triggers the audible cue. The user must drop out of the pose and re-enter it to re-trigger completion — this prevents accidental re-completion during a rest pause.
+
+**Why 60% as the hold threshold.** At 60%, the user's joint angles are within the tolerance band on the majority of weighted joints. A strict 80% threshold would frustrate beginners; a lenient 40% threshold would fire on casual near-misses. 60% is consistent with the threshold used in the Google ML Kit PoseClassifier sample and the Perez-Testor study's reported inter-practitioner variance (mean joint-angle SD of ~10° across joints, which maps to roughly a 30% score drop relative to a perfect practitioner on a 15° tolerance band).
+
+**Why not include a velocity component (punish fast transitions).** Velocity would require a second derivative of the landmark positions, which is already noisy from MediaPipe jitter even after the one-euro filter. Minimum hold time (2–3 s) implicitly penalises rushing through poses without adding noise sensitivity.
+
+### 2.5 Pose classification flow and debounce
+
+Every frame, after `ingestPoseLandmarks()` populates `liveKp`:
+
+```js
+function classifyPose() {
+    if (!yogaMode.enabled || !liveValid) return;
+    computeJointAngles();        // fills yogaMode.angles from liveKp
+    for (const p of yogaMode.activePoses) {
+        p.frameScore = scorePose(p);   // per-frame alignment_score_p
+    }
+    const best = yogaMode.activePoses.reduce((a, b) =>
+        b.frameScore > a.frameScore ? b : a
+    );
+    if (best.frameScore > SCORE_NO_POSE_FLOOR) {
+        yogaMode.streak = (yogaMode.candidate === best.id)
+            ? yogaMode.streak + 1 : 1;
+        yogaMode.candidate = best.id;
+    } else {
+        yogaMode.streak = 0;
+        yogaMode.candidate = null;
+    }
+    if (yogaMode.streak >= K_FRAMES && yogaMode.candidate !== yogaMode.current) {
+        yogaMode.current = yogaMode.candidate;
+        onPoseTransition(yogaMode.current);
+    }
+    updateYogaHUD();
+}
+```
+
+**K = 6 frames** (debounce depth). At 30 Hz this corresponds to a 200 ms lag from first matching pose to classification announcement. This is long enough to suppress a one-frame flicker from a mediocre landmark result but short enough to feel instantaneous to a human moving at yoga pace (typical transition speed: 1–3 seconds).
+
+Lowering K to 3 creates flickering when the user is near a pose boundary. Raising K to 12 introduces a 400 ms lag that makes the HUD feel unresponsive on quick transitions (e.g. Uttanasana → Ardha Uttanasana takes ~1 second in a vigorous practice). K = 6 is the correct value given the ~30 Hz landmark update rate.
+
+**SCORE_NO_POSE_FLOOR = 0.40.** If no pose scores above 40%, yoga-mode reports "no recognised pose" and does not transition. This prevents the classifier from latching onto the closest-matching pose during, say, walking across the room or sitting at a desk. At 40%, at least a plurality of the weighted joints must be within their tolerance band — a constraint that a non-yoga posture reliably fails.
+
+### 2.6 UI surfaces
+
+**Toggle in `#helpers` panel.** Added below the adam-mode row:
+
+```html
+<label class="yoga-toggle">
+    <input type="checkbox" id="yoga-mode-toggle">
+    <span>yoga-mode (instructional)</span>
+    <span class="swatch" style="color: var(--green)"></span>
+</label>
+```
+
+yoga-mode is orthogonal to adam-mode: both can be active simultaneously. It uses `data-yoga="on"` on `<body>`, not `data-theme`. The attribute is distinct so that CSS selectors like `:root[data-theme="adam"]` and `:root[data-yoga="on"]` compose without conflict.
+
+**`#yoga-panel` — bottom-centre overlay.** A new `<div id="yoga-panel" class="panel">` appears at the bottom centre of the viewport when yoga-mode is enabled. It is hidden (`display: none`) when yoga-mode is off, so it does not interfere with the existing layout.
+
+The panel contains:
+
+1. **Current pose name** — large (18px), Sanskrit name above English name below, amber colour. Falls back to "—" when no pose is recognised.
+2. **Alignment score ring** — a small SVG `<circle>` progress ring (r=22, stroke-dasharray) updating on every classified frame. Score 0–100 shown as integer inside the ring.
+3. **Hold-time progress bar** — a `<div class="bar-track">` identical in style to the CSI bars, filling from 0% to 100% as the hold-time accumulates. Resets on pose transition.
+4. **Instruction text** — one line from the current pose's `instruction` field, `font-size: 10px`, `color: var(--text-mute)`.
+5. **Visibility warning** — a `<span class="yoga-warn">` shown in `var(--red)` when `torso_not_visible` is true (see §2.7).
+
+**Sequence strip — top-centre.** A horizontal strip of 8 thumbnail slots (`<div class="yoga-strip">`) spanning the top of the viewport (z-index above the titlecard, below `#info`). Each slot contains the pose's stage number and a 3-letter abbreviation (TAD, URD, UTT, ARD, CAT, UPD, DOG, UT2). Slots are styled:
+
+- **Dimmed** (opacity 0.3, `var(--text-mute)` text) — not yet reached.
+- **Active** (opacity 1.0, `var(--amber)` border glow, pulsing) — current pose.
+- **Completed** (opacity 0.7, `var(--green)` checkmark `✓`, no glow) — held for `min_hold_s` seconds.
+
+The strip does not scroll. Eight slots at ~90px each fit a 720px-wide viewport. On narrower screens the strip compresses gracefully because the slots use `flex: 1` within a `display: flex` container.
+
+**Audible cue.** A single `<audio id="yoga-bell" src="data:audio/wav;base64,..." preload="auto">` element. The WAV is a 0.4-second C5 bell tone encoded inline as base64 (~12 KB). This preserves the single-file portability. It fires once on pose completion via `yogaBell.currentTime = 0; yogaBell.play()`. A `muted` toggle in `#helpers` (beneath the yoga-mode checkbox) allows the user to silence it: `<label><input type="checkbox" id="yoga-mute-toggle"> mute bell</label>`. The bell is muted by default (`yogaBell.muted = true`) to avoid startling first-time users.
+
+**Theme compatibility.** `#yoga-panel` and the sequence strip use only existing custom properties: `var(--bg-panel)`, `var(--border)`, `var(--amber)`, `var(--amber-hot)`, `var(--text)`, `var(--text-mute)`, `var(--green)`, `var(--red)`. No new CSS variables are introduced. The panel therefore inherits both the default dark theme and adam-mode automatically — the same mechanism described in ADR-169 §2.1.
+
+### 2.7 Camera / MediaPipe assumptions and graceful degradation
+
+**Expected input:** front-facing camera, full body from head to ankles in frame, neutral indoor lighting. The demo's existing camera pipeline already requests `{ video: { facingMode: 'user', width: 640, height: 480 } }`. No change to the MediaPipe setup.
+
+**Graceful degradation when body is partially out of frame.** MediaPipe assigns a `visibility` score in [0, 1] to each landmark. When a landmark's visibility drops below 0.35, yoga-mode treats that joint as missing:
+
+```js
+function effectiveWeight(jointName, angles) {
+    const vis = jointVisibility(jointName);   // min visibility of the 3 landmarks
+    if (vis < 0.35) return 0.0;              // joint masked — not counted
+    if (vis < 0.65) return angles.weight * (vis / 0.65);   // partial weight
+    return angles.weight;
+}
+```
+
+When two or more of the high-weight joints (knees, hips, torso_lean) are masked simultaneously, `Σ_j(weight_j)` falls below a minimum viable total, and `alignment_score_p` is set to 0 regardless of the numerator. This prevents spurious high scores from a partially visible body where only one or two low-weight joints (e.g. elbows) are visible and happen to match a pose.
+
+The `#yoga-panel` surfaces a `torso_not_visible` warning ("Move back — full body not in frame") in `var(--red)` whenever `liveVis[23] < 0.35 || liveVis[24] < 0.35` (left or right hip not visible). The hips are the reference joint for torso_lean and for hip-angle computation; their absence makes the entire classifier unreliable.
+
+### 2.8 Cross-demo applicability
+
+**yoga-mode ships in demo 05 only for the first iteration.** Demos 03 and 04 do not have a MediaPipe pipeline; there are no `liveKp` landmarks to score. Adding yoga-mode to them would require pulling in the entire MediaPipe Pose Heavy CDN script — changing those demos' character and load time.
+
+**New demo: `06-yoga-mode.html`.** A new file `examples/three.js/demos/06-yoga-mode.html` is introduced as a slimmed-down variant of demo 05 where yoga-mode is the primary focus rather than an optional overlay. Differences from demo 05:
+
+- The CSI panel (`#csi`) and the tomography sweep are hidden by default (`display: none`).
+- The `#yoga-panel` is expanded to a larger centre-screen layout with a bigger score ring (r=44) and larger pose name text (24px).
+- The sequence strip is rendered larger (100px slot width).
+- The `#helpers` panel shows only the yoga-related toggles (yoga-mode, adam-mode, mute bell).
+- The titlecard text reads "RuView · Yoga Mode".
+
+This file is created from a copy of demo 05 with the CSI and tomography sections stripped. It shares the `YogaMode` object and pose templates verbatim — no logic is duplicated.
+
+The decision to introduce a sixth demo file rather than making demo 05's yoga features more prominent is: demo 05 is a complete multi-feature demo (CSI + MediaPipe + IK retarget); demo 06 is a single-purpose instructional demo. Evaluators who want to show the yoga system without the RF sensing noise get demo 06.
+
+### 2.9 Persistence
+
+User settings are persisted in `localStorage` under the `ruview.yoga.*` namespace:
+
+| Key | Type | Value shape | Default |
+|---|---|---|---|
+| `ruview.yoga.enabled` | boolean string | `"true"` or `"false"` | `"false"` |
+| `ruview.yoga.muted` | boolean string | `"true"` or `"false"` | `"true"` |
+| `ruview.yoga.tolerance_scale` | float string | `"0.5"` to `"2.0"` | `"1.0"` |
+| `ruview.yoga.sequence` | JSON string | `["tadasana","urdhva_hastasana",…]` | full 8-pose sequence |
+
+`tolerance_scale` is a global multiplier applied to every `tolerance_deg` value in every template. A scale of 0.5 makes the classifier strict (tight bands); a scale of 2.0 makes it forgiving (wide bands). The HUD exposes this as a simple "Difficulty" slider: Easy (2.0×), Normal (1.0×), Strict (0.5×). The default is Normal.
+
+`ruview.yoga.sequence` allows an operator to load a custom subset or reordering of the 8 poses, or to load additional poses added via `YogaMode.addPose()`. The array contains pose `id` strings. On load, yoga-mode resolves each ID against the registered template map; unknown IDs are skipped with a console warning.
+
+All `localStorage` accesses are wrapped in try/catch to handle privacy-restricted origins.
+
+### 2.10 JS API surface
+
+yoga-mode exposes a clean internal module object. Because the demo is a single-file HTML with no ES module bundler, the pattern is a plain object literal assigned to a local `const`:
+
+```js
+const YogaMode = {
+    // ---- Lifecycle ----
+    init(opts = {}) {},       // wire up UI, register pose templates, restore localStorage
+    enable() {},              // set data-yoga="on", show #yoga-panel, start classifying
+    disable() {},             // remove data-yoga="on", hide #yoga-panel, reset state
+
+    // ---- Classification callbacks ----
+    onPoseChanged(cb) {},     // cb(poseId: string | null) — fires on confirmed transition
+    onPoseScored(cb) {},      // cb(scores: {[poseId]: number}) — fires every frame
+    onPoseCompleted(cb) {},   // cb(poseId: string, holdMs: number) — fires on hold completion
+
+    // ---- Template management ----
+    addPose(template) {},     // validate and register a custom pose template
+    removePose(id) {},        // remove a template by id (built-ins can be removed)
+    poses() {},               // returns Array<PoseTemplate> — current registered set
+
+    // ---- State accessors ----
+    currentPose() {},         // returns current confirmed pose id or null
+    currentScore() {},        // returns alignment score [0,1] of current pose or 0
+    angles() {},              // returns the latest computed joint angles object
+
+    // ---- Sequence control ----
+    resetSequence() {},       // clears all completion state, restarts from stage 1
+    setSequence(ids) {},      // replace active sequence with a custom id array
+
+    // Internal state — not part of the public API:
+    _state: { enabled, candidate, current, streak, holdStart, completedSet }
+};
+```
+
+`onPoseChanged`, `onPoseScored`, and `onPoseCompleted` follow the same pattern as the demo's existing event hooks: they register a single callback (last-writer wins, not an array). This is sufficient for a single-file demo where there is at most one consumer per event. A future multi-listener pattern would need a `listeners` array; that is out of scope.
+
+`addPose(template)` validates the template schema before registering it. A template missing `joint_targets` or with an `id` that contains non-alphanumeric characters is rejected with a `console.error` and returns `false`. Valid templates return `true`.
+
+### 2.11 Pose templates — Sun Salutation A joint targets
+
+The full 8-pose template set. Angle targets are derived from Perez-Testor et al. (2019) Vicon measurements and Iyengar alignment geometry. Tolerances are set to twice the reported inter-practitioner SD (~10°) rounded to the nearest 5°, then scaled by the user's `tolerance_scale`.
+
+**Stage 1 — Tāḍāsana (Mountain Pose)**
+
+All joints extended. Body in anatomical position. Baseline for comparison.
+
+```js
+{ id: "tadasana", name_en: "Mountain Pose", name_sa: "Tāḍāsana", stage: 1,
+  min_hold_s: 3,
+  joint_targets: {
+    left_knee:    { angle_deg: 180, tolerance_deg: 10, weight: 1.0 },
+    right_knee:   { angle_deg: 180, tolerance_deg: 10, weight: 1.0 },
+    left_hip:     { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    right_hip:    { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    torso_lean:   { angle_deg:   0, tolerance_deg: 10, weight: 1.2 },
+    left_elbow:   { angle_deg: 180, tolerance_deg: 20, weight: 0.4 },
+    right_elbow:  { angle_deg: 180, tolerance_deg: 20, weight: 0.4 },
+  },
+  instruction: "Stand tall. Feet hip-width, weight even. Arms at sides. Lengthen through the crown.",
+}
+```
+
+**Stage 2 — Ūrdhva Hastāsana (Upward Salute)**
+
+Arms sweep overhead. Shoulders maximally abducted. Distinguishing feature: both elbows extended and arms overhead (shoulder angle approaches 180° abduction). Perez-Testor reports shoulder elevation of 183° at peak overhead position.
+
+```js
+{ id: "urdhva_hastasana", name_en: "Upward Salute", name_sa: "Ūrdhva Hastāsana", stage: 2,
+  min_hold_s: 2,
+  joint_targets: {
+    left_shoulder:  { angle_deg: 165, tolerance_deg: 20, weight: 1.2 },
+    right_shoulder: { angle_deg: 165, tolerance_deg: 20, weight: 1.2 },
+    left_elbow:     { angle_deg: 180, tolerance_deg: 15, weight: 0.8 },
+    right_elbow:    { angle_deg: 180, tolerance_deg: 15, weight: 0.8 },
+    left_knee:      { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    right_knee:     { angle_deg: 180, tolerance_deg: 12, weight: 0.8 },
+    torso_lean:     { angle_deg:   0, tolerance_deg: 15, weight: 0.7 },
+  },
+  instruction: "Inhale. Sweep arms overhead. Palms face each other. Gaze forward or slightly up.",
+}
+```
+
+**Stage 3 — Uttānāsana (Standing Forward Fold)**
+
+Deep hip flexion. Torso approaches vertical-inverted. Perez-Testor reports hip flexion of 134°. The angle at the hip joint as computed by our triplet (shoulder→hip→knee) goes to ~30° as the torso folds toward the legs. Knees remain extended.
+
+```js
+{ id: "uttanasana", name_en: "Standing Forward Fold", name_sa: "Uttānāsana", stage: 3,
+  min_hold_s: 3,
+  joint_targets: {
+    left_hip:    { angle_deg:  40, tolerance_deg: 25, weight: 1.2 },
+    right_hip:   { angle_deg:  40, tolerance_deg: 25, weight: 1.2 },
+    left_knee:   { angle_deg: 175, tolerance_deg: 15, weight: 1.0 },
+    right_knee:  { angle_deg: 175, tolerance_deg: 15, weight: 1.0 },
+    torso_lean:  { angle_deg:  85, tolerance_deg: 20, weight: 1.0 },
+  },
+  instruction: "Exhale. Fold forward from the hips. Let the crown of the head drop toward the floor.",
+}
+```
+
+**Stage 4 — Ardha Uttānāsana (Half Lift / Flat-Back)**
+
+Torso lifts to horizontal. Hip angle opens to ~90°. Spine neutral. This is the most distinctive pose for classification: it is the only one where the torso is neither upright nor fully folded — the `torso_lean` angle is ~90° and the hips are also ~90°. Perez-Testor reports the half-lift as an intermediate transition posture; the distinguishing cue is the simultaneous hip angle and spine neutral (not flexed).
+
+```js
+{ id: "ardha_uttanasana", name_en: "Half Lift", name_sa: "Ardha Uttānāsana", stage: 4,
+  min_hold_s: 2,
+  joint_targets: {
+    left_hip:    { angle_deg:  90, tolerance_deg: 20, weight: 1.2 },
+    right_hip:   { angle_deg:  90, tolerance_deg: 20, weight: 1.2 },
+    left_knee:   { angle_deg: 175, tolerance_deg: 12, weight: 0.8 },
+    right_knee:  { angle_deg: 175, tolerance_deg: 12, weight: 0.8 },
+    torso_lean:  { angle_deg:  90, tolerance_deg: 15, weight: 1.2 },
+    left_elbow:  { angle_deg: 180, tolerance_deg: 20, weight: 0.5 },
+    right_elbow: { angle_deg: 180, tolerance_deg: 20, weight: 0.5 },
+  },
+  instruction: "Inhale. Lift the chest. Flat back. Fingertips on the shins or floor. Gaze forward.",
+}
+```
+
+**Stage 5 — Catvāri / Chaturanga Daṇḍāsana (Four-Limbed Staff)**
+
+Plank lowered. Elbows at 90°. Body horizontal. This is the hardest pose to classify from a front-facing camera alone: the body is horizontal and the depth axis is ambiguous. The key discriminator is `elbow_angle ≈ 90°` combined with `hip ≈ 180°` (no flexion) and `torso_lean ≈ 90°`. Note: from a front-facing camera, a person in Chaturanga facing the camera appears foreshortened. yoga-mode accepts this limitation and primarily tracks Chaturanga as the transition between Ardha Uttanasana and Upward Dog in the sequence, with lower weight on spatial cues and higher weight on elbow angle. Iyengar geometry specifies elbows at 90° against the body.
+
+```js
+{ id: "chaturanga", name_en: "Four-Limbed Staff", name_sa: "Catvāri / Chaturanga Daṇḍāsana", stage: 5,
+  min_hold_s: 2,
+  joint_targets: {
+    left_elbow:   { angle_deg:  90, tolerance_deg: 20, weight: 1.5 },
+    right_elbow:  { angle_deg:  90, tolerance_deg: 20, weight: 1.5 },
+    left_hip:     { angle_deg: 175, tolerance_deg: 15, weight: 0.8 },
+    right_hip:    { angle_deg: 175, tolerance_deg: 15, weight: 0.8 },
+    left_knee:    { angle_deg: 175, tolerance_deg: 15, weight: 0.6 },
+    right_knee:   { angle_deg: 175, tolerance_deg: 15, weight: 0.6 },
+    torso_lean:   { angle_deg:  90, tolerance_deg: 20, weight: 0.7 },
+  },
+  instruction: "Lower down. Elbows at 90°, hugged to the ribs. Body in one straight line.",
+}
+```
+
+**Stage 6 — Ūrdhva Mukha Śvānāsana (Upward-Facing Dog)**
+
+Hips extend, spine extends (backbend), shoulders over wrists, knees off floor. Distinguishing feature: hips are near 160–180° (extended), which is the opposite of Uttanasana's deep flexion. The `torso_lean` reverses from ~90° horizontal to approaching 0° or slightly past vertical (slight backbend). Perez-Testor's spine extension of 44° is the reference for the backbend component; the hip angle opens to near-full extension.
+
+```js
+{ id: "urdhva_mukha_svanasana", name_en: "Upward-Facing Dog", name_sa: "Ūrdhva Mukha Śvānāsana", stage: 6,
+  min_hold_s: 2,
+  joint_targets: {
+    left_hip:     { angle_deg: 165, tolerance_deg: 20, weight: 1.2 },
+    right_hip:    { angle_deg: 165, tolerance_deg: 20, weight: 1.2 },
+    left_elbow:   { angle_deg: 170, tolerance_deg: 20, weight: 0.8 },
+    right_elbow:  { angle_deg: 170, tolerance_deg: 20, weight: 0.8 },
+    left_knee:    { angle_deg: 170, tolerance_deg: 20, weight: 0.6 },
+    right_knee:   { angle_deg: 170, tolerance_deg: 20, weight: 0.6 },
+    torso_lean:   { angle_deg:  15, tolerance_deg: 20, weight: 0.8 },
+  },
+  instruction: "Press the tops of the feet down. Lift the chest. Shoulders away from the ears. Gaze forward.",
+}
+```
+
+**Stage 7 — Adho Mukha Śvānāsana (Downward-Facing Dog)**
+
+Hips high. Inverted V. The most geometrically distinct pose in the sequence: high hips, extended knees, arms overhead-ish (shoulder angle ~150° relative to torso), torso_lean ~90° but in the opposite direction to Chaturanga (body weight shifted back over the heels). The hip angle as measured by our shoulder→hip→knee triplet is ~80–110° (the pelvis is high, creating a roughly right-angle fold at the hip). Perez-Testor reports the hip-angle transition from Chaturanga to Downward Dog as the largest single-frame angle change in the sequence (~120° excursion), making it the easiest pose to classify correctly.
+
+```js
+{ id: "adho_mukha_svanasana", name_en: "Downward-Facing Dog", name_sa: "Adho Mukha Śvānāsana", stage: 7,
+  min_hold_s: 5,
+  joint_targets: {
+    left_hip:     { angle_deg:  90, tolerance_deg: 25, weight: 1.2 },
+    right_hip:    { angle_deg:  90, tolerance_deg: 25, weight: 1.2 },
+    left_knee:    { angle_deg: 180, tolerance_deg: 15, weight: 1.0 },
+    right_knee:   { angle_deg: 180, tolerance_deg: 15, weight: 1.0 },
+    left_shoulder: { angle_deg: 150, tolerance_deg: 25, weight: 0.8 },
+    right_shoulder: { angle_deg: 150, tolerance_deg: 25, weight: 0.8 },
+    torso_lean:   { angle_deg:  90, tolerance_deg: 20, weight: 0.7 },
+  },
+  instruction: "Hips up and back. Heels reaching toward the floor. Arms and ears in one line. Breathe.",
+}
+```
+
+**Stage 8 — Uttānāsana (Standing Forward Fold, return)**
+
+Identical to stage 3 in geometry. Classified as stage 8 for sequence-tracking purposes only — same template joint targets, different `id` and `stage` value.
+
+```js
+{ id: "uttanasana_return", name_en: "Standing Forward Fold (return)", name_sa: "Uttānāsana", stage: 8,
+  min_hold_s: 2,
+  joint_targets: { /* same as stage 3 */ },
+  instruction: "Step or jump to the front. Exhale. Release the head. Return to stillness.",
+}
+```
+
+Distinguishing stages 3 and 8 is handled by the sequence-tracking layer, not by the classifier. If yoga-mode is in stage 7 (Downward Dog) and detects a forward-fold shape, it advances to stage 8 rather than regressing to stage 3. If yoga-mode is in stages 1–2 and detects a forward-fold shape, it advances to stage 3. The sequence tracks forward direction only; there is no backward regression in the first implementation.
+
+### 2.12 Test plan
+
+**Manual — live camera:**
+Stand in front of the workstation USB camera (ruvzen, confirmed front-facing in CLAUDE.local.md). Enable yoga-mode from `#helpers`. Cycle through all 8 poses in order. For each pose: verify the HUD shows the correct Sanskrit and English name within 2 frames (~67 ms) of entering the pose, the alignment score exceeds 60%, and the sequence strip advances. Verify no pose is misclassified when standing in a casual at-rest position (score should be below 40% floor for all 8 poses).
+
+**Synthetic — test mode triggered by `?test=1` URL parameter:**
+When `location.search` includes `test=1`, yoga-mode enters a headless test mode: instead of reading from `liveKp`, it reads from a pre-recorded `YOGA_TEST_FIXTURES` object — one synthetic landmark array per pose, generated at authoring time by capturing the real `liveKp` values during a manual demo session.
+
+```js
+if (new URLSearchParams(location.search).has('test')) {
+    for (const fixture of YOGA_TEST_FIXTURES) {
+        ingestPoseLandmarks(fixture.landmarks);
+        classifyPose();
+        const result = YogaMode.currentPose();
+        console.assert(result === fixture.expected_id,
+            `FAIL: ${fixture.expected_id} got ${result}`);
+    }
+    console.log('YogaMode tests complete');
+}
+```
+
+The fixture set is 8 entries (one per pose). Each entry is a hard-coded `landmarks` array of 33 objects with `{x, y, z, visibility}` values. These fixtures are inlined in the `<script>` block, gated behind `if (urlParams.has('test'))` so they are never executed in normal operation.
+
+**Negative test:** A ninth fixture entry with the user standing in a neutral at-rest position (arms at sides but knees slightly bent, casual posture — not a yoga pose). Assert `YogaMode.currentPose() === null` (no pose above the 0.40 floor).
+
+**Regression guard for joint-angle computation:** A tenth fixture that hard-codes known landmark positions forming a right angle at the left knee (three points forming a precise 90° angle). Assert `YogaMode.angles().left_knee` is within ±0.5° of 90.
+
+### 2.13 Rejected alternatives
+
+| Alternative | Rejected because |
+|---|---|
+| Train a custom MLP on a labelled yoga dataset | No labelled dataset in this codebase. Training requires hundreds of examples per class, a train/test pipeline, and a serialized model file — all incompatible with a single-file demo. Joint-angle matching achieves equivalent discrimination for 8 geometrically distinct poses with zero training data. |
+| Use a paid SaaS pose-classification API (e.g. a commercial yoga scoring cloud service) | Introduces an external network dependency, a per-request cost, and a privacy concern (camera frames leaving the browser). Pure client-side is a hard requirement. |
+| Ship audio/video instructional content (video of an instructor demonstrating each pose) | Massively increases the demo's asset footprint. A single instructor video per pose at 15 fps, 10 seconds, compressed, is ~500 KB × 8 = 4 MB minimum. The inline base64 bell (~12 KB) is the correct granularity of embedded media for this demo. |
+| Ship a backend yoga-tracking session record (store per-session completion data to a server) | No backend endpoint exists or is planned for the demos. Client-only; persistence via `localStorage`. |
+| Integrate with the Rust `pose_tracker.rs` now | Convention mismatch (BlazePose-33 vs COCO-17) documented in §1.3 but the cost of bridging it outweighs the benefit for a demo. The bridge is deferred: yoga-mode in JS is valuable without it. Rust integration becomes tractable once a WebSocket protocol for streaming joint angles (not raw CSI) from the sensing server is defined — a separate ADR. |
+| Use MediaPipe Tasks `PoseLandmarker` with a built-in `PoseClassifier` task | The Tasks API requires loading a `.task` bundle (~4 MB) from CDN at runtime. Demo 05 already uses the older `@mediapipe/pose@0.5` CDN script; switching APIs would require rewriting the entire landmark ingest pipeline. The classifier task is a black box undebuggable in DevTools. Threshold matching is fully transparent. |
+| Put yoga-mode on `data-theme` alongside adam-mode | yoga-mode is not a theme — it is a feature toggle. Mixing it with the theme attribute would prevent simultaneous adam-mode + yoga-mode activation and would conflate presentation with functionality. Separate `data-yoga="on"` attribute is the correct model. |
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- The retargeting pipeline in demo 05 gains a per-pose regression test harness (`?test=1`) at no additional tooling cost.
+- yoga-mode operates on the existing `liveKp` stream — zero additional CPU cost beyond a few arctangent calls per frame (~50 µs at 30 Hz).
+- The pose-scoring formula is fully deterministic and inspectable: `console.log(YogaMode.angles())` in DevTools shows every joint angle on every frame.
+- Demo 06 provides a clean instructional-first presentation that separates yoga-mode from the RF sensing visualisations, making the feature accessible to a fitness-context audience.
+- The `YogaMode.addPose()` API allows operators to extend the template library without touching core logic — enabling future pose sets (Warrior series, Yin postures) as a follow-on.
+- The `tolerance_scale` persistence allows the same demo codebase to serve both beginners (2× tolerance) and experienced practitioners (0.5× tolerance) without code changes.
+
+### 3.2 Negative
+
+- Two HTML files to maintain (`05` and `06`) where previously there was one. Mitigated by the fact that yoga-mode logic is identical between them — demo 06 is a layout variant, not a code fork.
+- Chaturanga Dandasana classification is inherently degraded from a front-facing camera (the body is horizontal; the depth axis is ambiguous). The classifier can detect the pose if the user faces the camera sideways (profile view), but the existing camera setup on ruvzen is front-facing. This is a known limitation, documented in the instruction text ("face the camera from the side for best Chaturanga detection").
+- The inline base64 bell WAV adds ~12 KB to the HTML file size. Negligible at the scale of the demo but noted.
+- `localStorage` namespace `ruview.yoga.*` adds four keys per origin. No conflict with `ruview.theme` from adam-mode.
+
+### 3.3 Risks
+
+| Risk | Likelihood | Mitigation |
+|---|---|---|
+| MediaPipe visibility scores are unreliable for floor-level landmarks (ankles, feet) during Dog poses | Medium | `effectiveWeight()` already masks low-visibility joints; Dog-pose templates weight knees (visible) more than ankles (may be occluded). |
+| The `?test=1` fixture landmarks become stale if the coordinate-space transform in `ingestPoseLandmarks()` changes | Low | Fixtures store raw `liveKp` world-space values, not normalized MediaPipe coords. If `ingestPoseLandmarks()` changes its output schema, the fixtures will produce obviously wrong joint angles in the assertion step — the failure is loud, not silent. |
+| Sequence-strip animation (CSS pulsing glow on the active stage) triggers repaint on every frame at 30 Hz | Low | The pulse is a CSS `animation` on `opacity` — composited by the GPU, no layout reflow. Negligible cost. |
+| User's camera position cuts off the hips (e.g. laptop on a desk) — `torso_not_visible` fires immediately | High for laptop use | The warning instructs the user to step back. This is the correct behaviour. Future: add a "camera too close" heuristic based on the ratio of shoulder distance to image width. |
+| Stage 8 (Uttanasana return) is classified identically to stage 3 by the angle classifier alone — the sequence layer must correctly disambiguate them | Medium | The sequence-tracking layer uses monotonic forward-only progression. Stage 3 can only fire when the current sequence position is 2 (after Urdhva Hastasana); stage 8 can only fire when the current sequence position is 7 (after Downward Dog). The classifier produces the angle score; the sequence layer decides which stage to credit. If the user skips a pose, the sequence layer waits — it does not leap to stage 8 from stage 2 even if a forward-fold shape is detected. |
+
+---
+
+## 4. Implementation plan
+
+Moderate scope — two HTML files, no build step, no new external dependencies.
+
+1. **Define the `YOGA_POSES` array** — 8 template objects as specified in §2.11, inline in the `<script>` block of demo 05.
+2. **Implement `computeJointAngles()`** — read from the existing `liveKp` array, fill a `yogaAngles` object using the 9 joint triplets in §2.2.
+3. **Implement `scorePose(template)`** — the weighted-sum formula from §2.4, respecting `effectiveWeight()` for visibility masking.
+4. **Implement `classifyPose()`** — argmax with K=6 debounce as in §2.5; call from the existing `requestAnimationFrame` loop after `applyRetargeting()`.
+5. **Add `#yoga-panel` markup and CSS** — bottom-centre panel, score ring, hold-time bar, instruction text, visibility warning. All styles via existing custom properties.
+6. **Add the sequence strip** — `#yoga-strip` top-centre, 8 flex slots, 3-state styling (dimmed/active/completed).
+7. **Wire the `#helpers` toggle** — `yoga-mode-toggle` checkbox and `yoga-mute-toggle` checkbox; `localStorage` persistence.
+8. **Add `YogaMode` object** — wrapping steps 1–7 with the API surface from §2.10.
+9. **Add `YOGA_TEST_FIXTURES` and the `?test=1` harness** — 10 fixture entries (8 positive, 1 negative, 1 angle-computation).
+10. **Create `06-yoga-mode.html`** — copy of demo 05 with CSI/tomography sections hidden, larger yoga panel layout.
+11. **Manual validation** — stand in front of ruvzen camera, cycle all 8 poses, verify classification and sequence advancement.
+
+Acceptance criteria:
+
+- All 8 poses classified correctly in the `?test=1` synthetic harness (assertions pass with no console errors).
+- The negative fixture (casual stand) produces `currentPose() === null`.
+- The angle-computation fixture (`left_knee` at a known 90°) asserts within ±0.5°.
+- Manual: each of the 8 Sun Salutation A poses classified within 2 frames when held correctly.
+- Alignment score exceeds 60% when the user matches the pose by self-assessment.
+- Sequence strip advances in order; completed poses show green checkmark.
+- Bell fires on completion (when unmuted).
+- adam-mode + yoga-mode simultaneously active: both panels visible, correct theme.
+- `localStorage` persists enabled-state and tolerance-scale across page reloads.

+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — clean-with-evidence, 4 regression pins added |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **CSI-DESERIALISER-HARDENING** |

+
+## Context
+
+The beyond-SOTA security sweep (branch `feat/v2-beyond-sota-sweep`) reviewed each
+`v2/` crate for real, reproducible defects. Two crates had no prior dedicated
+security ADR:
+
+- **`wifi-densepose-core`** — the dependency root for all 12 downstream crates
+  (types, traits, error types, CSI frame primitives). A defect here is a
+  force-multiplier: every consumer inherits it.
+- **`wifi-densepose-cli`** — the user-facing entrypoint
+  (`calibrate`/`calibrate-serve`/`enroll`/`train-room`/`room-watch` + MAT-gated),
+  which parses untrusted UDP CSI packets and operator-supplied paths.
+
+A **specific hypothesis** motivated the core review. Three earlier reviews in
+this campaign found a systemic **NaN-state-poisoning bug class** in crates that
+depend on core (`wifi-densepose-calibration`, `-vitals`, `-geo`): a non-finite
+(NaN/Inf) input latched into persistent filter/accumulator state (IIR `y1/y2`,
+running mean, Welford/von-Mises accumulator, voxel grid) → silent **permanent**
+feature failure. The load-bearing question for this review: **does that bug class
+originate in a shared `wifi-densepose-core` primitive** (making the right fix a
+single root fix), or was it independently re-implemented in each downstream
+crate (making the three existing local fixes complete)?
+
+## Decision
+
+Record the review outcome and lock in the existing DoS guards with regression
+tests. **No production code is changed** — both crates were already hardened
+(ADR-136 acceptance criteria + `sanitize_room_id`); the gap was *untested*
+guards, which a future refactor could silently remove.
+
+### Load-bearing question — VERDICT: **NO** (the NaN class does not live in core)
+
+`wifi-densepose-core` exposes **no stateful accumulator of any kind** — no
+Welford/running-mean, no von-Mises/circular-mean, no IIR/biquad filter state, no
+voxel grid.
+
+- **MEASURED:** `grep` over `core/src` for
+  `welford|von_mises|biquad|y1|y2|running_mean|accumulat|voxel|self.*+=` matched
+  only the `InvalidState` *error* enum variant, "reset state" doc comments, and a
+  test-only LCG — **zero** stateful logic. The only float math in core is
+  construction-time projection (`CsiFrame::new` → amplitude/phase via `mapv`) and
+  pure stateless `utils` functions; nothing persists across frames.
+- **Corroboration:** `wifi-densepose-calibration::Features::from_series`
+  (`extract.rs:103–133`) already filters non-finite samples → `Features::ZERO`.
+  The downstream fixes are independently re-implemented, confirming each crate
+  rolls its own accumulator and each local fix is correct and complete. **A fix
+  in core would be a no-op (there is nothing to fix).**
+
+Consequence: the NaN-state-poisoning class is a *downstream-local* pattern, not a
+core-rooted defect. No hidden fourth instance exists in the shared primitive.
+
+### Findings (all pins — guards already present, now tested)
+
+| # | Location | Guard (pre-existing) | Regression pin | Evidence (MEASURED) |
+|---|----------|----------------------|----------------|---------------------|
+| 1 | `core` `types.rs:801` `from_canonical_bytes` | `saturating_mul` shape-vs-length check before `Vec::with_capacity(rows*cols)` | `canonical_decode_oversized_shape_is_bounded_not_allocated` | With guard removed: **panics `capacity overflow` at `types.rs:801`**; with guard: passes |
+| 2 | `core` `types.rs` decoder | typed `CanonicalDecodeError`, never panics | `canonical_decode_never_panics_on_arbitrary_bytes` (fuzz sweep) | panic-free on arbitrary bytes |
+| 3 | `cli` `calibrate.rs:276–291` | length check `buf.len() < 20 + n_pairs*2` before `Array2::zeros(n_antennas*n_subcarriers)` | `test_parse_csi_packet_oversized_claim_is_rejected_not_allocated` | 255×65535 claim in a 2 KB packet → `None` (no allocation) |
+| 4 | `cli` `calibrate.rs` parser | `None`-returning on malformed input | `test_parse_csi_packet_never_panics_on_arbitrary_bytes` (fuzz sweep) | panic-free on arbitrary UDP bytes |
+
+### Dimensions confirmed clean (with evidence)
+
+1. **Panic-on-adversarial-input = 0** — `from_canonical_bytes` returns a typed
+   error for every malformed class; `parse_csi_packet` returns `None`. Both
+   fuzz-swept panic-free.
+2. **NaN handling** — `Confidence::new` rejects NaN
+   (`!(0.0..=1.0).contains(&NaN)` ⇒ `Err`); `compute_bounding_box` /
+   `to_flat_array` are NaN-tolerant (f32 min/max ignore NaN).
+3. **Empty-frame safety** — `amplitude_variance` / `mean_amplitude` are
+   panic-free on an empty `Array2` (ndarray 0.17 returns finite / `None`).
+4. **Unbounded-memory DoS** — bounded in both deserialisers (findings 1 & 3).
+5. **Path traversal** — `calibrate-serve` defends every client-supplied
+   `room_id`/`bank`/`baseline` via `sanitize_room_id` (`[A-Za-z0-9_-]`, 64-char
+   cap) with existing tests; bearer-auth gate + non-loopback-bind warning present.
+   `mat export` writes to an operator-supplied `PathBuf` (acceptable CLI behavior).
+6. **Secrets** — `--token` is read from `CALIBRATE_TOKEN` env, never embedded.
+
+## Validation
+
+- `cargo test -p wifi-densepose-core` → **35 → 37** lib passed, 0 failed (+3 doctests)
+- `cargo test -p wifi-densepose-cli --no-default-features` → **24 → 26** passed, 0 failed
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed

+  (core/cli are off the signal proof path — confirms no pipeline alteration)
+
+## Consequences
+
+### Positive
+- Two CSI deserialisers (the untrusted-input boundary of both the library root
+  and the network-facing CLI) now have their DoS guards pinned against
+  regression — a future refactor that drops a length check fails CI.
+- The NaN-state-poisoning class is settled as downstream-local; reviewers no
+  longer need to suspect a shared-root defect, and the three prior local fixes
+  are confirmed complete.
+
+### Negative
+- None. Test-only change; no behavior or API change.
+
+### Neutral
+- The `core` portion is also noted in ADR-127 §9 (shared security-review log);
+  this ADR is the canonical record for the `wifi-densepose-cli` review.

+# ADR-173: Metric-Locked PCK/MPJPE Accuracy Harness
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — implemented, deterministically tested |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **METRIC-LOCK** |
+| **Amends** | ADR-155 (generalizes the torso-only `metrics_core::pck_canonical` to a selectable normalization) |
+| **Motivated by** | `docs/research/sota-nn-train-benchmark-brief.md` (PR #1090) |
+
+## Context
+
+The beyond-SOTA SOTA-research brief (PR #1090) identified the single biggest
+threat to any "beyond-SOTA" accuracy claim this project makes: **metric
+ambiguity**. Three PCK@20 numbers circulate, computed under three *different and
+unstated* normalizations, so they cannot be compared:
+
+- **96.09–96.61%** — WiFlow-STD reproduction, **image/bounding-box-normalized** PCK (the looser convention).
+- **81.63%** — an internal MM-Fi number reported as **"torso-PCK"** (tighter).
+- **61.1%** — GraphPose-Fi (arXiv 2511.19105), **standard torso-diameter** PCK on the MM-Fi random split (the academic frontier).
+
+The project has been burned by this twice: a previously-published 92.9% was
+retracted because it used **absolute-pixel** normalization, not torso. Until
+there is *one canonical, documented, tested* PCK definition — and every reported
+number carries the definition it was computed under — no accuracy comparison is
+credible, and the "prove everything" bar cannot be met for the benchmark half of
+the work.
+
+This is measurement infrastructure, not an accuracy claim. The deliverable's job
+is to make the metric **unambiguous and reproducible**, so future numbers are
+comparable and an unlabeled PCK is structurally impossible.
+
+## Decision
+
+Add a metric-locked accuracy harness as a new module
+`v2/crates/wifi-densepose-train/src/accuracy.rs` (404 non-test lines; inline
+deterministic tests bring the file to 708), re-exported at the crate root. It
+**extends, not duplicates** — it reuses `metrics_core`'s geometric primitives
+(`bounding_box_diagonal`, canonical hip indices `CANON_LEFT_HIP/RIGHT_HIP`), so
+there remains exactly one implementation of each geometric reference; the
+existing ADR-155 `pck_canonical` (torso-only) is unchanged and this generalizes
+it.
+
+### Public API
+
+- `enum PckNormalization { TorsoDiameter, BoundingBoxDiagonal, AbsolutePixels(f32) }`
+  — the three conventions the three historical numbers used, now **explicit and
+  selectable**. `.label()` / `.tolerance(...)`.
+- `pck_at(pred, gt, vis, k, norm) -> (correct, total, pck)` — PCK@k =
+  fraction of *visible* keypoints whose predicted-vs-GT distance ≤ the tolerance,
+  where tolerance = `k%` of the chosen normalizer (or an absolute threshold for
+  `AbsolutePixels`).
+- `mpjpe(pred, gt, vis) -> f32` — mean per-joint position error (2D/3D, coordinate
+  units; mm for mm inputs). Re-exported crate-root as `pck_mpjpe` to avoid
+  colliding with the existing `eval::mpjpe`.
+- `struct PoseAccuracy { pck_at: BTreeMap<u8,f32>, mpjpe, normalization, n_keypoints, n_frames }`
+  — **a reported number always carries its `normalization`**; an unlabeled PCK is
+  structurally impossible to produce through this surface.
+- `struct PoseFrame { pred, gt, visibility }` + `accuracy_report(frames, ks, norm) -> PoseAccuracy`
+  (micro-averaged over keypoints).
+
+### Correctness is proven by hand-computed deterministic tests (no GPU, no data)
+
+The tests construct synthetic keypoint sets whose PCK/MPJPE can be computed by
+hand, and assert the harness matches. Highlights (all pass):
+
+| Test | Construction | Expected |
+|------|--------------|----------|
+| perfect_prediction | pred==gt | PCK=1.0 (all 3 norms), MPJPE=0 |
+| all_just_outside | every error just past τ@20 | PCK=0.0 |
+| half_in_half_out | 2 exact, 2 just outside | PCK=0.5 |
+| **three_normalizations (KEY PROOF)** | identical pred; nose err .06, shoulder .10, hips exact | torso=**0.50**, bbox=**1.00**, abs(.08)=**0.75** |
+| mpjpe_2d / mpjpe_3d | (3,4)→5 / (1,2,2)→3 | 2.5 / 3.0 |
+| mpjpe_excludes_invisible | invisible joint err 100 ignored | 5.0 |
+| zero_torso_unscoreable | coincident hips | `(0,0,0.0)`, **not** false-perfect |
+| no_visible_keypoints | vis=∅ | `(0,0,0.0)` |
+| nan_coords | one NaN pred coord | counted wrong, **no panic** |
+| empty report | no frames | 0.0, **not** NaN |
+| bbox≥torso ordering | same frames | bbox-PCK ≥ torso-PCK |
+
+### The key proof (the ambiguity is real and quantified)
+
+Identical predictions, three declared normalizations → **0.50 / 1.00 / 0.75**.
+Mechanism: the bbox diagonal `√(0.20² + 0.80²) = 0.825` is ~4× the hip-span torso
+`0.20`, so τ@20 is 0.165 (bbox) vs 0.040 (torso) — the looser image-normalized
+convention passes joints the strict torso convention rejects. This is *exactly*
+why 96% / 81.6% / 61% cannot be lined up without declaring the enum, demonstrated
+in-code.
+
+## Validation
+
+- `cargo test -p wifi-densepose-train --no-default-features` → lib **191 → 206**
+  (+15), `test_metrics` **12 → 14** (+2), doc-tests 8 — **0 failed**.
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed.
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash
+  `f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a` **unchanged**
+  (off the signal proof path — confirms no pipeline alteration).
+
+## Consequences
+
+### Positive
+- The three historical PCK numbers can now be **recomputed under one declared
+  definition** and compared honestly. The retracted-number class of error
+  (silent normalization mismatch) is structurally prevented going forward.
+- Establishes the measurement substrate for the beyond-SOTA target: GraphPose-Fi
+  cross-environment **PCK@20 = 12.9%** (standard torso PCK) is now a number this
+  harness can produce comparably.
+
+### Negative
+- None functional. The harness is additive; no existing metric path changed.
+
+### Neutral
+- Producing actual model numbers under this harness requires the trained models +
+  datasets (MM-Fi) and, for cross-domain splits, is the next sub-deliverable of
+  the benchmark/optimization milestone — out of scope here (this ADR is the
+  *instrument*, not the *reading*).

+# ADR-174: CI Bench-Regression Gate (Compile-Verify)
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — implemented, caught one real bit-rotted bench |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **BENCH-GATE** |
+| **Milestone** | benchmark/optimization re-balance — sub-deliverable 8.3 |
+| **Motivated by** | `docs/research/sota-nn-train-benchmark-brief.md` (target 3: criterion benches as CI regression baselines) |
+
+## Context
+
+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,cir,…}_bench`,
+`wifi-densepose-mat/detection_bench`, `wifi-densepose-nn/{inference,native_conv}_bench`,
+`wifi-densepose-engine/engine_cycle`, …). Because **benches are not part of
+`cargo test`**, nothing in CI compiled them — so they bit-rot silently the moment
+a public API they call changes, and the rot is invisible until someone manually
+runs `cargo bench` months later.
+
+The SOTA brief named "wire existing criterion benches into CI as regression
+baselines" as a concrete benchmark-hygiene target. The honest difficulty: true
+*timing*-regression gating on shared GitHub runners is unreliable — wall-clock
+varies 2–3× run-to-run (a captured 10-sample run showed `float_l2/512` ranging
+307–444 ns), so a hard threshold or a cross-runner `criterion --baseline` compare
+(baseline and PR land on different physical machines) would manufacture false
+regressions. A gate that cries wolf gets disabled.
+
+## Decision
+
+Add `.github/workflows/bench-regression.yml` with **two jobs of explicitly
+different authority** — and do NOT pretend to gate on timing.
+
+### `bench-compile` — HARD GATE (real regression detection)
+`cargo bench --workspace --no-default-features --no-run` compiles + links every
+default-feature bench (no measurement → fully deterministic), plus a
+`--features cir` compile of the gated `cir_bench`. Benches aren't in `cargo test`,
+so this is the genuine guard: **the build fails the moment a bench stops
+compiling.**
+
+### `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 (1 s warm-up / 2 s
+measure / 10 samples), targeted per-`--bench`, and uploads logs as an artifact.
+Every number it produces is **informational only** — explicitly stated in the
+workflow header.
+
+### What is NOT done, and why (honest scope)
+No timing-regression gate, no committed baseline JSON. The workflow header
+documents the exact condition under which true timing-gating becomes honest: a
+frequency-pinned **self-hosted** runner with a generous (>2×) floor. A
+cross-runner baseline would be dishonest, so none is committed.
+
+### Proof it matters (MEASURED)
+Running the new gate on the current tree immediately caught
+`wifi-densepose-mat/detection_bench` failing to compile:
+`error[E0063]: missing field last_rssi in initializer of SensorPosition` — the
+struct gained a field; the bench was never updated. **Fixed** in the same 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`). The gate paid for itself on its first run.
+
+### Exclusions (documented in-workflow)
+- `ruvector/crv_bench` — its crates.io dep `ruvector-crv 0.1.1` fails to build on
+  stable (upstream `E0308` in `stage_iii.rs`); excluded with a re-add condition.
+- `onnx_bench` / `mqtt_throughput` — feature-gated (ort / mqtt), left to their
+  crates' own workflows. `wasm-edge/process_frame_bench` — workspace-excluded.
+
+Conventions mirror existing workflows: `submodules: recursive` (the workspace
+path-deps `vendor/rufield`), Swatinem/rust-cache `workspaces: v2`, Tauri/GTK apt
+deps (a `--workspace` bench link pulls the whole graph), path-filtered triggers.
+
+## Validation
+
+- **Bit-rot caught + fixed** (above), re-verified `--no-run`.
+- **MEASURED locally** (`--no-default-features`, Windows): nvsim, ruvector
+  (sketch/fusion/ann), signal/cir_bench, mat/detection_bench (post-fix),
+  vitals, ruview-swarm/swarm_bench all compile; fast subset runs (`nvsim
+  pipeline_run/d1/256` ≈ 55 µs; `ruvector sketch_hamming` ≈ 3–7 ns vs `float_l2`
+  ≈ 63–371 ns).
+- `cargo test -p wifi-densepose-mat --no-default-features` → 166/6/2 passed, 0 failed.
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash
+  `f8e76f21…46f7a` unchanged.
+- **Honest limitation:** the full `--workspace --no-run` could not be
+  end-to-end validated on this Windows box (`desktop` needs GTK, `candle-core`
+  fails on MSVC, `swarm_bench` LTO-links OOM under parallel pressure — all
+  Windows-env artifacts; each affected bench compiles standalone here). **The
+  first green Linux CI run on the PR is the authoritative proof of the
+  `--workspace` step.**
+
+## Consequences
+
+### Positive
+- Bench bit-rot is now a hard CI failure, not a silent surprise — the 26 benches
+  stay compilable as the APIs they exercise evolve.
+- The benchmark-infrastructure half of the DoD (step 5) is satisfied honestly,
+  setting up the next sub-deliverable (QAT-int8 measurement) to be
+  regression-protected.
+
+### Negative / Neutral
+- No automated timing-regression detection (deliberate — see scope). Revisit only
+  with a frequency-pinned self-hosted runner.

+
+## Context
+
+The SOTA brief characterized the int8 edge story for the WiFlow-STD pose net as
+"fully characterized" for PTQ on the **published 2.23M** model (static QDQ
+conv-only = the sweet spot; dynamic int8 ≈ no-op on this all-conv net), and named
+**QAT-int8 on the strictly-dominating 843,834-param "half" model** as "the one
+untested edge lever." This ADR is the reading of that lever — a MEASURED
+fp32-vs-int8 trade-off for the half model, not a claim.
+
+The half model (`half_best.pth`, 843,834 params) is the efficiency-sweep winner
+from ADR-152 (`run_sweep.py` VARIANTS[0]: `tcn=[270,220,170,120]`,
+`conv=[4,8,16,32]`, `attn_groups=4`). Its fp32 accuracy was recorded in the sweep;
+this ADR re-measures it under the locked normalization and quantizes it.
+
+**The whole point of this deliverable is reproducibility.** Every number below was
+produced by running `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py`
+on host `ruvultra` (RTX 5080, torch 2.11.0+cu128) against the real checkpoint and
+the real seed-42 test split. The script + the exact command + the recorded stdout
+**is** the proof artifact. Nothing here is estimated.
+
+## Decision
+
+Quantize the half model to int8 with **both** levers and report both honestly:
+
+1. **QAT (primary target)** — FX graph-mode quantization-aware training, fbgemm
+   backend, 3 epochs of fake-quant fine-tuning from `half_best.pth` (AdamW lr 2e-5,
+   the existing `PoseLoss`), then `convert_fx` to a true int8 graph.
+2. **PTQ static QDQ (the brief's "sweet spot", measured as the honest fallback)** —
+   FX graph-mode static PTQ, fbgemm, calibrated on 64 train batches.
+
+### Locked normalization (ADR-173)
+
+**Torso-diameter PCK** — neck (keypoint idx 2) → pelvis (idx 12) distance — the
+standard MM-Fi/GraphPose-Fi convention. This is exactly the default
+`use_torso_norm=True` path of the upstream harness's `utils/metrics.calculate_pck`.
+The **same** `calculate_pck`/`calculate_mpjpe` that produced the sweep's fp32
+numbers scores **both** fp32 and int8 here, so the comparison is metric-locked: no
+normalization is mixed, and the fp32 baseline reproduces the sweep's recorded
+`half` test numbers bit-for-bit (PCK@20 clean = 96.62%), confirming the harness is
+the same one.
+
+### Device note (why int8 is CPU)
+
+PyTorch int8 quantized kernels execute on CPU (fbgemm/x86), not CUDA. So int8 eval
+is CPU. To keep the accuracy delta device-matched (not confounding int8-vs-fp32
+with CPU-vs-GPU), the script measures an **fp32-CPU** baseline too. fp32-CPU and
+fp32-GPU agree to 4 decimals (PCK@20 clean 0.96623 vs 0.96623), so CPU/GPU
+introduces no drift — the int8 deltas below are pure quantization effect.
+
+## MEASURED results (clean test subset = 52,560 NaN-free windows; torso-PCK)
+
+Source: stdout of the run below + `~/wiflow-std-bench/sweep/int8/int8_results.json`.
+
+| model | quant | size (MB) | PCK@20 | PCK@50 | MPJPE | Δ PCK@20 | Δ PCK@50 | size win |
+|-------|-------|-----------|--------|--------|-------|----------|----------|----------|
+| **fp32** (cpu) | — | **3.351** | **96.62%** | **99.47%** | **0.008981** | — | — | 1.00× |
+| int8 PTQ static | PTQ | 1.046 | 40.98% | 94.98% | 0.038262 | **−55.64 pp** | −4.49 pp | 3.20× smaller |
+| int8 QAT (3 ep) | **QAT** | 1.043 | 67.48% | 98.69% | 0.026548 | **−29.15 pp** | −0.78 pp | 3.21× smaller |
+
+Full-test-set (54,000 windows incl. NaN-zero-filled files 487–499) tracks the
+clean subset: fp32 96.10% / int8-PTQ 41.11% / int8-QAT 67.48% PCK@20 — same shape,
+recorded in the JSON.
+
+### Verdict
+
+**int8 is NOT a win for this model at the tight PCK@20 edge target — honest no.**
+
+- **PTQ static collapses** (−55.64 pp PCK@20). Naive static QDQ destroys the half
+  model. The "sweet spot" characterization from the brief does not transfer from
+  the 2.23M model to this 843k model at the strict torso-PCK@20 threshold.
+- **QAT recovers a large share of the relative gap** (PTQ 40.98% → QAT 67.48%) but
+  still **loses 29.15 pp** at PCK@20 for a 3.21× size reduction. At the loose
+  PCK@50 threshold QAT is nearly lossless (−0.78 pp), i.e. coarse-localization
+  survives int8 but fine-localization does not.
+- The size win is real and consistent (3.2× smaller, 3.351 MB → ~1.04 MB), but
+  **3.2× compression at −29 pp PCK@20 is a bad trade** when the half model already
+  fits comfortably in edge flash at fp32. Recommendation: **keep fp32 (or fp16)
+  for the half model on the edge**; do not ship this int8 variant as-is.
+
+### Observed fake-quant → int8 conversion gap (disclosed, not hidden)
+
+During QAT the **fake-quant** model's val PCK@20 reached 83.45% (epoch 3), but the
+**converted int8** model scores 67.48% on test. A ~16 pp drop on `convert_fx` is a
+real effect — the fbgemm int8 kernels are not bit-identical to the fake-quant
+simulation (per-tensor activation quant + the axial-attention `einsum`/softmax path
+quantize worse than the straight-through estimate predicts). This gap is the honest
+reason QAT did not close the loss, and it is exactly the kind of number that would
+be invisible if one only reported the fake-quant proxy. We report the **converted
+int8** number as the deliverable, not the fake-quant proxy.
+
+## Reproduction

+```bash
+ssh ruvultra 'cd ~/wiflow-std-bench && source venv/bin/activate && \
+  python ~/quantize_half_int8.py --mode both --qat-epochs 3 2>&1'
+```
+
+- Script (committed): `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py`
+  (scp'd to `~/quantize_half_int8.py` on ruvultra for the run).
+- Inputs (on ruvultra, unmodified): `~/wiflow-std-bench/sweep/half_best.pth`,
+  `~/wiflow-std-bench/preprocessed_csi_data/` (seed-42 file-level 70/15/15 split),
+  upstream `models`/`dataset`/`utils/metrics`/`losses` (DY2434/WiFlow @ 06899d29,
+  Apache-2.0), and `sweep/model_compact.py` (the half-model definition).
+- Outputs (written, non-destructive): `~/wiflow-std-bench/sweep/int8/` —
+  `half_int8_qat.pth`, `half_int8_ptq_static.pth`, `int8_results.json`,
+  `int8_run.log`. **No existing file under `~/wiflow-std-bench` was modified.**
+- Run metadata: host `ruvultra`, GPU RTX 5080, torch `2.11.0+cu128`, fbgemm engine,
+  `date_utc 2026-06-15T12:35:06Z`, QAT ≈ 97 s/epoch.
+
+## What is MEASURED vs CLAIMED
+
+- **MEASURED:** every PCK/MPJPE/size number in the table; the fp32 baseline (which
+  reproduces the recorded sweep `half` numbers); the PTQ collapse; the QAT partial
+  recovery; the fake-quant→int8 conversion gap; the 3.2× size reduction.
+- **CLAIMED / not done here:** ONNX/TFLite export; on-real-edge (ESP32/Pi/Hailo)
+  latency or energy (int8 here is measured on x86 fbgemm, the dev box, **not** an
+  edge SoC — the size number transfers, a latency number does **not**); a
+  per-layer mixed-precision search that might keep the attention block in fp32; QAT
+  beyond 3 epochs or with learned-quant-range schedules. Those are the obvious next
+  levers if int8 is revisited; none is asserted as a result.
+
+## Honest scope / limitations
+
+- **Single eval split** — one seed-42 file-level test partition; no cross-room /
+  cross-environment generalization split (the GraphPose-Fi frontier from ADR-173 is
+  a separate, harder split and is not what is measured here).
+- **In-domain only** — these are in-distribution test numbers; they say nothing
+  about the cross-environment robustness gap.
+- **x86 int8, not edge-SoC int8** — accuracy and size transfer to an edge int8
+  runtime; the runtime/latency does not (different kernels, different SoC). No
+  latency claim is made.
+- **QAT lightly tuned** — 3 epochs, single LR, default fbgemm qconfig. A longer /
+  better-tuned QAT might narrow the −29 pp, but on the evidence here int8 does not
+  reach fp32 at PCK@20, and that is the reportable result today.
+
+## Consequences
+
+### Positive
+- The "one untested edge lever" (QAT-int8 on the half model) is now MEASURED. The
+  edge int8 question for the half model is answered with reproducible numbers: at
+  the strict PCK@20 target it loses, and we can say so with a committed script.
+- Establishes a reusable, metric-locked quantization+eval harness
+  (`quantize_half_int8.py`) for any future int8 attempt on these compact variants.
+
+### Negative
+- None to the codebase (additive script + ADR + CHANGELOG only; no production Rust
+  or signal-pipeline change; Python deterministic proof hash
+  `f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a` unchanged).
+
+### Neutral
+- The negative verdict means the half model stays fp32/fp16 on the edge for now.
+  int8 for these compact pose nets is parked pending the next-lever work above.

+# ADR-176: `ruview-swarm` NaN-Fail-Open Safety Review
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — 4 real safety bugs fixed + pinned; 2 issues documented for follow-up |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **SWARM-FAILCLOSED** |
+| **Reviews** | ADR-148 (`ruview-swarm` drone swarm control plane) |
+| **Milestone** | #9 (ungated-crate security sweep) — crate 1 of 4 |
+
+## Context
+
+`ruview-swarm` (ADR-148) is the drone swarm control plane — hierarchical-mesh
+topology, Raft consensus, MARL, CSI sensing payload, MAVLink/PX4 command
+dispatch. It is the highest-stakes of the four never-reviewed v2 crates: a defect
+here can produce an **unsafe physical drone command**. It had no prior security
+ADR.
+
+### Trust-boundary map
+Untrusted input enters via `SwarmOrchestrator::receive_peer_state` /
+`receive_peer_detection`, which accept full `DroneState` / `CsiDetection` serde
+structs with **f64/f32 fields and no finite-check**, and via
+`SwarmConfig`/`FhssConfig`/`Geofence` deserialization. The MAVLink wire formats in
+`mavlink_messages.rs` are **integer-encoded** (i32 mm / u8) and provably cannot
+carry NaN — so the NaN class is reachable through the **serde struct path, not the
+MAVLink decode path**. Commands flow out to a `FlightController` (PX4/ArduPilot).
+
+The unifying bug class found: **IEEE-754 NaN/Inf silently defeating a safety
+comparison** (`NaN < threshold` evaluates to `false`), causing safety logic to
+**fail OPEN**. This is distinct from — but rhymes with — the NaN-state-poisoning
+class found earlier in calibration/vitals/geo (there, NaN latched into persistent
+state; here, NaN slips through a one-shot guard). Both are "non-finite input
+defeats logic," and the fix discipline is the same: **reject non-finite at the
+trust boundary, fail CLOSED.**
+
+## Decision
+
+Fix the four reachable fail-open bugs by making each safety predicate
+non-finite-aware and fail-closed, each pinned by a fails-on-old test. Document
+two further genuine issues that need larger, riskier changes rather than churning
+them in a security pass.
+
+### Findings fixed (all MEASURED fails-on-old)
+
+| # | Severity | File:line | Issue | Fix | Pin (old behavior) |
+|---|----------|-----------|-------|-----|--------------------|
+| F1a | **HIGH** | `failsafe/mod.rs:51` | `nearest_neighbor_dist < collision_dist_m` fails open on a NaN peer position → **collision avoidance silently disabled** | `!is_finite() ||` → `EmergencyDiverge` | `test_nan_neighbor_distance_fails_closed_to_diverge` (old → `Nominal`) |
+| F1b | **HIGH** | `failsafe/mod.rs:75` | NaN `battery_pct` bypasses every battery check → drone stays Nominal on unknown battery | `!is_finite() ||` → `ReturnToHome` | `test_nan_battery_fails_closed_to_rth` (old → `Nominal`) |
+| F2 | **MEDIUM** | `security/geofence.rs:33` | NaN `z` altitude skips the altitude-breach check and point-in-polygon returns `Safe` → silent geofence bypass | leading non-finite coord → `HardBreach` | `test_nan_altitude_fails_closed` (old → `Safe`) |
+| F3 | **MEDIUM/DoS** | `security/antijamming.rs:65,71,102` | empty deserialized `channels_mhz` → `% 0` **panic** in `next_hop`/`current_channel_mhz`/`evasive_hop`/`tick`, crashing the radio task | `len == 0` early-return (`0.0` sentinel) | `test_empty_channels_does_not_panic` (old → panic `divisor of zero`) |
+| F4 | **LOW** | `sensing/multiview.rs:70` | NaN `victim_position` passes the `is_some()` filter and propagates into the fused "confirmed victim" location dispatched to the swarm | require finite confidence + position (drop) | `test_nan_victim_position_dropped_from_fusion` (old → non-finite fused position) |
+
+### Dimensions confirmed clean (with evidence)
+- **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]` decode path exists.
+- **UWB/GPS anti-spoofing NaN-safe** — `(gps_dist - uwb_dist).abs() <= tol` already fails CLOSED on a NaN range (counts as inconsistent → spoof rejected); covered by `test_spoofed_gps_invalid`.
+- **Bounded grid / no allocate-from-length-field** — `ProbabilityGrid` bounds-checks `cx/cy`; `pos_to_cell` uses saturating `as u32` (no UB).
+- **Mesh `nearest_k` NaN-safe sort** — `partial_cmp(..).unwrap_or(Equal)` cannot panic on NaN.
+- **No hardcoded secrets** — `MavlinkSigner` key is constructor-injected `[u8;32]`; grep-confirmed nothing embedded.
+
+### Documented, not fixed (genuine — deferred to avoid churn/regression risk)
+
+1. **Raft `AppendEntries` lacks the Log-Matching consistency check**
+   (`topology/raft.rs:187`). A follower appends a leader's entries when
+   `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. A correct fix reworks the log-append plus the
+   caller-side vote-tally contract (the existing `handle_message` delegates
+   tallying to the caller) — a larger change with test-rewrite risk, so it is
+   recorded here rather than rushed in a security pass.
+2. **`MavlinkSigner::verify` uses a non-constant-time tag `==` and has no
+   replay/timestamp-window rejection** (`security/mavlink_signing.rs:64`). The
+   module doc already flags the replay limitation as a demo/test simplification.
+   Hardening (constant-time compare + monotonic timestamp window) is a focused
+   follow-up.
+
+These two are the recommended scope of the next `ruview-swarm` hardening pass.
+
+## Validation
+
+- `cargo test -p ruview-swarm --no-default-features` → **117 → 123** passed, 0 failed (+6 pins).
+- All 6 new tests MEASURED fails-on-old (2× `Nominal`, `Safe`, panic `divisor of zero`, non-finite fused position); pass on the fix.
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed.
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash
+  `f8e76f21…46f7a` unchanged (ruview-swarm off the signal proof path).
+
+## Consequences
+
+### Positive
+- Four reachable fail-open paths in a *physical-safety* control plane (collision
+  avoidance, battery RTH, geofence, anti-jamming radio task) now fail CLOSED on
+  hostile/degenerate input, each regression-pinned.
+- Extends the "non-finite input defeats logic" defense from the state-poisoning
+  variant (calibration/vitals/geo) to the fail-open-comparison variant.
+
+### Negative / Neutral
+- Two genuine issues (Raft log-matching, MAVLink signer) remain open by choice —

+# ADR-177: `nvsim` Degenerate-Input Hardening (NV-Diamond Simulator)
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — 2 real MEDIUM bugs fixed + pinned; determinism preserved |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **NVSIM-FAILCLOSED** |
+| **Reviews** | ADR-089 (`nvsim` NV-diamond magnetometer pipeline simulator) |
+| **Milestone** | #9 (ungated-crate security sweep) — crate 2 of 4 |
+
+## Context
+
+`nvsim` (ADR-089) is a standalone, **WASM-ready** deterministic NV-diamond
+magnetometer pipeline simulator — a forward-only leaf:
+`scene → source → propagation → NV ensemble → digitiser → MagFrame + SHA-256
+witness`. It has no network surface, so the real attack surface is **degenerate
+physical-parameter input** crossing the external boundary — specifically the
+WASM `config_json` / `scene_json` entry points.
+
+Two properties matter for this crate that don't for others: it is billed
+**deterministic** (a published cross-machine witness must reproduce bit-exactly),
+and under `panic=abort` WASM any panic **aborts the whole module**. So a
+config-induced panic is a denial-of-service, and a silent numeric corruption
+defeats the simulator's entire purpose.
+
+## Decision
+
+Fix the two reachable degenerate-input bugs at their funnel points, each pinned
+by a fails-on-old test, **without perturbing the deterministic happy path** (the
+guards fire only on non-finite / degenerate input; the published witness is
+unchanged).
+
+### Findings fixed (both MEASURED-reproduced)
+
+| # | Severity | Location | Issue | Fix |
+|---|----------|----------|-------|-----|
+| NVSIM-DT-01 | MEDIUM (DoS) | `pipeline.rs:58,95` | `dt = config.dt_s.unwrap_or(1.0 / f_s_hz)`; an external `f_s_hz == 0.0` → `dt = +Inf` → `(dt*1e6) as u64` saturates to `u64::MAX` → `(sample as u64) * dt_us` **panics `attempt to multiply with overflow`** at `sample ≥ 2` (debug/WASM-abort; garbage `t_us` in release). MEASURED: panic at `pipeline.rs:95:30`. | Sanitise `dt` (non-finite/non-positive → 1 µs fallback), cap the `u64` cast at `u64::MAX`, `saturating_mul` the timestamp — no config can overflow it. |
+| NVSIM-NAN-01 | MEDIUM (silent corruption) | funnel `digitiser.rs::adc_quantise` (root: near-field clamp bypass in `source.rs`) | A non-finite scene param (NaN/Inf dipole position, Inf moment, NaN loop radius) **bypasses the near-field clamp** (`NaN < R_MIN_M == false` → the `1/r³` path runs → NaN field), and at the ADC `NaN as i32 == 0` (Rust saturating cast) emits a frame `b_pt=[0,0,0]` with **`ADC_SATURATED` CLEAR** — indistinguishable from a legitimate zero-field reading. MEASURED: `b=[NaN,NaN,NaN] sat=false` → `b_pt=[0,0,0] flags=0b0000`. | `adc_quantise`: any non-finite input → code `0` **with the saturation flag raised**; the pipeline's existing `adc_sat` OR-reduction propagates `ADC_SATURATED` onto the frame, making the corruption visible downstream. |
+
+This is the same **NaN-fail-open / NaN-poisoning** family seen across
+calibration/vitals/geo and ruview-swarm — non-finite input defeating a guard —
+but bounded here to a single frame (no cross-timestep accumulator).
+
+### Dimensions confirmed clean (with evidence)
+
+1. **Determinism integrity — clean.** One RNG only: `ChaCha20Rng::seed_from_u64(seed)`,
+   fully caller-seeded (grep: one `seed_from_u64`, **zero** `thread_rng`/`getrandom`/
+   `SystemTime`/`Instant`/`HashMap`); `Cargo.toml` pins `rand`/`rand_chacha`
+   `default-features=false` (no OS entropy). Box–Muller draws
+   `gen_range(f64::EPSILON..=1.0)` (avoids `ln(0)=-Inf` by construction). Frame
+   bytes fixed LE; source summation order fixed by `Vec` order. **The published
+   cross-machine witness `cc8de9b0…93b4` (`proof_witness_publishes_a_known_value`)
+   passes UNCHANGED after both fixes** — the happy path is byte-identical; guards
+   touch only degenerate inputs. *Attested caveat (not a finding): libm
+   `cos`/`ln`/`sqrt` could differ x86↔wasm; the witness is documented as
+   x86_64-captured.*
+2. **Panic-free deserialisation — clean.** `MagFrame::from_bytes` validates
+   len/magic/version, then per-field `buf[a..b].try_into().expect(...)` are over
+   fixed sub-ranges of an already-length-checked 60-byte buffer (provably
+   infallible). No `unsafe`, no `panic!`/`unreachable!` in production; every other
+   `unwrap`/`expect` is `#[cfg(test)]`.
+3. **Div-by-zero / numerical landmines — clean.** `dipole_field`/`current_loop_field`
+   clamp `r_norm < R_MIN_M` before `1/r³`,`1/r²` (finite inputs); `shot_noise_floor`
+   guards `denom <= 0`; `vec3_normalise` guards `n < 1e-20`. The only hole was the
+   NaN *bypass* of the clamp — closed at the ADC funnel (NVSIM-NAN-01).
+
+## Validation
+
+- `cargo test -p nvsim --no-default-features` → **50 → 53** passed, 0 failed (+3 pins:
+  `degenerate_zero_sample_rate_does_not_panic`,
+  `non_finite_scene_input_flags_frame_instead_of_silently_zeroing`,
+  `adc_quantise_flags_non_finite_as_saturated`).
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed.

+

+| WDP-DESK-01 | MODERATE | `src/commands/discovery.rs:438` (`configure_esp32_wifi`) | Webview-supplied `ssid`/`password` are concatenated into newline-terminated serial commands (`wifi_config {} {}\r\n`, `set ssid {}\r\n`) with **no validation** → a `\r\n` in either field **injects an arbitrary follow-up firmware command** (`reboot`, `erase_nvs`) across the IPC trust boundary. | `validate_wifi_credentials()` — WPA2 length bounds (SSID 1–32, password 8–63) **+ reject all control chars** (`char::is_control()`), called fail-closed before any serial write. |
+| WDP-DESK-02 | MODERATE | `capabilities/default.json:7-8` | `shell:allow-execute` + `shell:allow-open` granted to the webview but **unused** (Rust spawns via `std::process::Command`; the UI uses only `dialog.open`). A webview compromise (a UI-dependency XSS) → arbitrary **unscoped host command execution**. | Removed both `shell:` permissions (kept `core:default` + the two in-use `dialog:` perms); regenerated `gen/schemas/capabilities.json` now asserts `["core:default","dialog:allow-open","dialog:allow-save"]`. |
+
+Both are MODERATE (not HIGH): each requires a webview compromise or a malicious
+local caller to weaponize. The unifying lesson is **least privilege at the IPC
+boundary** — validate every webview-supplied argument that reaches a serial/FS/
+process sink, and grant only the capabilities actually exercised.
+
+### Tauri-command + capability audit (every handler)
+
+All 30+ command handlers were mapped. Only `configure_esp32_wifi` lacked input
+validation on a string that reached a command sink (WDP-DESK-01). Every
+subprocess uses `Command::new(prog).args([...])` (argv vector — no shell-string
+interpolation), so `port`/`source`/`chip`/`baud` cannot inject a second command
+even unvalidated. `tauri.conf.json` ships **no** `fs`/`http` plugin and **no**
+`"all":true`/`"$HOME/**"` scope; after WDP-DESK-02 the allowlist is minimal.
+
+### Dimensions confirmed clean (with evidence)
+
+1. **Directory traversal / arbitrary file** — path args (`firmware_path`/`wasm_path`)
+   are blobs the local user selects via the native `dialog.open` picker; settings
+   I/O is a fixed filename under `app_data_dir`. No attacker-named path sink.
+2. **Shell-string injection** — every subprocess is an argv vector; grep found no
+   shell-string interpolation anywhere.
+3. **SSRF-to-secret** — `node_ip`-built URLs target the local ESP32 mesh and return
+   only device status JSON; no credential returned to the webview.
+4. **Panic-on-input** — handlers use `.map_err(|e| e.to_string())?`; the one
+   `expect` is guarded by an `is_none()` early-return; provision/discovery
+   deserializers bounds-check every slice index (NVS size capped ≤ 4096).
+5. **Hardcoded secrets** — `ota_psk` is a per-call `Option<String>`, never embedded;
+   grep for embedded keys/tokens over `src/` is empty.
+6. **Shell plugin genuinely unused** — `tauri_plugin_shell` is `init()`-ed but its
+   `Command`/`open` API is never invoked from Rust or the TS UI (which imports only
+   `@tauri-apps/plugin-dialog`) — confirming WDP-DESK-02 is safe to remove.

+# ADR-179: `wifi-densepose-occworld-candle` Checkpoint-Load Hardening
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — 1 HIGH + 2 LOW bugs fixed + pinned (MEASURED on Windows) |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **OCCWORLD-DTYPE** |
+| **Reviews** | `wifi-densepose-occworld-candle` (Candle occupancy-world model) |
+| **Milestone** | #9 (ungated-crate security sweep) — crate 4 of 4 — **CLOSES the milestone** |
+
+## Context
+
+`wifi-densepose-occworld-candle` is a Candle-based occupancy-world model
+(VQ-VAE + transformer over occupancy tokens). The real risk surface for an ML
+crate is degenerate-input / malformed-weights handling: a `#[forbid(unsafe_code)]`
+crate can still **panic** (a DoS, and under WASM an abort) when a tensor op hits an
+inconsistent shape. The crate **builds and tests on Windows**, so all findings are
+MEASURED.
+
+## Decision
+
+Fix the three reachable bugs, each pinned by a fails-on-old test; attest the rest
+clean with evidence.
+
+### Findings fixed (all MEASURED)
+
+| # | Severity | Location | Issue | Fix |
+|---|----------|----------|-------|-----|
+| 1 | **HIGH** | `model.rs:95` (`Dtype::I32 => Some(DType::I64)`) | **Crash on any int32-tensor checkpoint.** An I32 byte buffer (4 B/elem) is handed to `from_raw_buffer(.., I64, shape, ..)`; candle derives `elem_count = data.len()/8`, **halving** the count while keeping the original shape → a tensor that claims 2× its storage. Reading it **panics** with a slice-OOB (`range end index 6 out of range for slice of length 3`) inside candle-core. A checkpoint with any int32 tensor (index/buffer tensors are common in PyTorch exports) → **DoS on load**. | Map `I32 → DType::I32`, `I16 → DType::I16` (both first-class candle dtypes). Pinned by `int32_tensor_loads_with_consistent_shape_and_values` (panics on old, passes on new). |
+| 2 | LOW | `inference.rs::predict` | Frame/batch dims weren't validated (only H/W/D were): `f_in > num_frames*2` over-indexes the temporal embedding → a cryptic candle `InvalidIndex` *error* (not a panic — candle bounds-checks); zero frame/batch feeds a zero-element tensor. | Boundary guard rejects zero / over-capacity frame+batch with a clear `ShapeMismatch`. 5 pins. |
+| 3 | LOW | `vqvae.rs:141` (`z.elem_count() / last`) | **Divide-by-zero panic** in public `VQCodebook::encode` on a rank-0 / empty-last-dim tensor (`last == 0`). | Fail-closed guard returns a clear error. Pinned by `encode_rejects_scalar_without_panicking`. |
+
+The HIGH finding is the notable one: the crate's own dtype mapping **defeated**
+the upstream `safetensors::validate()` byte-length guarantee by misdeclaring the
+dtype — the one place malformed/widened weights could reach a panicking candle op.
+
+### Dimensions confirmed clean (with evidence)
+
+- **Panic surface** — grep for `unwrap()/expect()/panic!/unreachable!` across `src/`
+  → **zero in production paths**; all ops use `?`/`map_err`; the `last().unwrap_or(&0)`
+  is now guarded. `as` casts operate only on config-bounded/internal values.
+- **NaN-state-poisoning (the named class) — N/A.** The engine is **stateless between
+  `predict` calls** (no persistent world-model buffer to latch into), and input is
+  `u8` class indices (non-finite input structurally impossible). NaN weights flow to
+  `argmax` (deterministic, bounded to a valid class index) — no panic, no persistence.
+- **Unbounded alloc / shape-data mismatch from malformed weights** — defended upstream
+  by `safetensors::validate()` (overflow-checked `nelements*dtype.size()` vs declared
+  byte range + contiguous-offset + buffer-length checks), rejected before reaching
+  candle. Finding #1 was the one place the crate defeated that guarantee.
+- **Model/path loading** — `load`/`load_safetensors` check `path.exists()` → typed
+  `CheckpointNotFound`; corrupt bytes → `CheckpointParse` (pinned). No path-traversal
+  surface (caller-supplied path, opened read-only, never joined with untrusted segments).
+- **Secrets** — grep clean (only `token_h`/`token_w` config fields match `token`).
+- **Determinism** — the crate's central honesty claim, verified by the pre-existing
+  `tests/predict_honesty.rs` (3 tests, still pass).
+- `unsafe_code = "forbid"` in the manifest.
+
+## Validation
+
+- `cargo test -p wifi-densepose-occworld-candle --no-default-features` → **31/31**
+  (lib 17, checkpoint_loading 4, input_validation 5, predict_honesty 3, doctests 2),
+  0 failed.
+- `cargo test --workspace --no-default-features` → 0 failed across every crate (a lone
+  `wifi-densepose-desktop --test api_integration` "Access is denied (os error 5)" was a
+  Windows file-lock/AV flake — re-ran isolated 21/21, unrelated).
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash `f8e76f21…46f7a`
+  unchanged (occworld off the signal proof path).
+
+## Consequences
+
+### Positive
+- A checkpoint-load DoS (the int32 dtype-widening panic) and two degenerate-input
+  panics are closed in the world-model crate, each pinned. **Milestone #9 (all 4
+  ungated crates) is complete.**
+
+### Negative / Neutral
+- None. Guards reject only malformed/degenerate inputs.

+| **Supersedes** | none |
+
+## Context
+
+RuView (WiFi-DensePose) is a deep stack — 15 Rust crates, an ESP32 firmware line,
+a sensing-server, a CLI, ~180 ADRs, a calibration pipeline, training recipes, and a
+hard cultural rule that **every claim must be independently reproducible** (the
+"prove everything" ethos, after the project was accused of AI-slop). The barrier to
+entry is correspondingly steep: a newcomer who wants to "set up WiFi sensing" must
+discover the right firmware variant, provision an ESP32 over a Windows-only Python
+subprocess, point it at the sensing-server, run `calibrate` → `enroll` →
+`train-room`, and know which numbers are MEASURED vs CLAIMED. We already encode this
+knowledge as **Claude Code subagents** (`ruview-onboarding-guide`,
+`ruview-config-engineer`, `ruview-training-engineer`) — but those only exist inside
+*this* repo's `.claude/agents/`, only on Claude Code, and only for someone who has
+already cloned the monorepo.
+
+Separately, this session shipped **MetaHarness** (`metaharness@0.1.15`): a tool that
+*"mints a custom AI agent harness from any repo"*, runnable on **9 hosts**
+(claude-code, codex, pi-dev, hermes, openclaw, rvm, copilot, opencode,
+github-actions) over a wasm-primary / NAPI-RS-fallback **kernel**, with a
+**cost-optimal model router** (`@metaharness/router`, the productized DRACO Phase-2
+k-NN finding) and ed25519/SLSA/SBOM provenance baked in. Crucially, MetaHarness
+**already ships a `vertical:ruview` template** in its template list. That template
+is generic scaffolding; it is not wired to RuView's actual tools, agents, or the
+"prove everything" guardrails.
+
+The gap: **there is no single, host-portable, provenance-signed entry point that
+gives any user an AI agent that actually knows how to operate RuView.** A user
+should be able to run one command —
+
+```bash
+npx ruview
+```
+
+— in an empty directory (or alongside an ESP32) and get an agent harness that can
+onboard them, configure firmware, drive a live capture, train a room model, and
+**refuse to overstate accuracy** — on whichever coding host they already use.
+
+## Decision
+
+**Mint a first-class RuView agent harness from this repo using MetaHarness, harden
+its `vertical:ruview` template into a RuView-specific harness with a real MCP tool
+surface and the project's honesty guardrails, and publish it as `npx ruview`.**
+
+`npx ruview` is *not* a new runtime. It is a **thin, versioned distribution** of a
+MetaHarness harness: the kernel + host adapters + a RuView "genome" (skills, agents,
+MCP tools, guardrails) generated from and pinned against this monorepo. The harness
+is the product; `npx ruview` is the front door.
+
+### Why mint-from-repo instead of hand-writing a harness
+
+MetaHarness's value here is exactly the work we would otherwise hand-roll across 9
+hosts: host-specific config (`.claude/settings.json` MCP + hooks for claude-code,
+the codex/copilot/opencode equivalents), the kernel that abstracts wasm-vs-native,
+the cost router, and the provenance chain. We write the **RuView knowledge once** as
+host-neutral genome assets; MetaHarness projects them onto each host adapter. This
+also keeps the harness regenerable: when the CLI or an ADR changes, re-mint and
+re-pin rather than maintaining 9 divergent copies.
+
+### What the harness contains (the RuView genome)
+
+1. **Skills / playbooks** (host-neutral markdown, projected to each host's skill
+   format):
+   - `onboard` — zero-to-sensing path picker (Docker demo / repo build / live
+     ESP32), the physics caveats, the hardware table. Port of
+     `ruview-onboarding-guide`.
+   - `provision-node` — ESP-IDF v5.4 Windows-subprocess build/flash/provision flow
+     (the exact MSYSTEM-stripped invocation from `CLAUDE.local.md`), firmware
+     variant selection (8MB display / 4MB no-display / C6), NVS + WiFi + channel /
+     MAC-filter overrides (ADR-060).
+   - `calibrate-room` — `baseline → enroll → extract → train` via the
+     `wifi-densepose` CLI (`calibrate`/`calibrate-serve`/`enroll`/`train-room`/
+     `room-watch`, ADR-151).
+   - `train-pose` — camera-supervised + camera-free training, the MEASURED-vs-CLAIMED
+     discipline, the mean-pose baseline check (ADR-079, ADR-152, ADR-181).
+   - `verify` — run the witness bundle + Python proof (`verify.py` → VERDICT: PASS),
+     ADR-028.
+   - Ports of `ruview-config-engineer` and `ruview-training-engineer`.
+
+2. **MCP tool surface** (`@metaharness/kernel`-hosted MCP server, one schema per
+   capability — see "MCP tools" below). This is what makes the harness *operate*
+   RuView, not just talk about it.
+
+3. **Guardrails** (the differentiator): the harness's system prompt and a
+   pre-output hook enforce the "prove everything" rule — accuracy numbers must be
+   tagged MEASURED (with a reproducer) or CLAIMED; the agent must run the mean-pose
+   baseline before quoting PCK; firmware fixes are never presented as
+   hardware-validated without a real boot log (the exact discipline this session
+   followed for `v0.8.1-esp32`).
+
+4. **Host adapters** — claude-code first (P1), then codex / opencode / copilot /
+   pi-dev / hermes / rvm / github-actions (P3+), each via the published
+   `@metaharness/host-*` package.
+
+5. **Router** — `@metaharness/router` routes each step to the cheapest adequate
+   model (e.g. a var-rename or a log-grep → Haiku; calibration-math reasoning or a
+   security review → Sonnet/Opus), mirroring the repo's 3-tier routing (ADR-026).
+
+### MCP tools (the operational surface)
+
+| Tool | Wraps | Purpose |
+|------|-------|---------|
+| `ruview.onboard` | docs + agent | Pick a setup path, print the next concrete command |
+| `ruview.node.flash` | ESP-IDF subprocess (ADR `CLAUDE.local.md`) | Build + flash a firmware variant to a COM port |
+| `ruview.node.provision` | `provision.py` | Set SSID/password/target-ip/channel/MAC-filter over serial |
+| `ruview.node.monitor` | pyserial | Stream boot log; assert CSI is flowing (MGMT+DATA) |
+| `ruview.server.up` | sensing-server | Start the Axum sensing-server (`:3000`/`:5005`/`:8765`) |
+| `ruview.calibrate` | `wifi-densepose calibrate`/`enroll`/`train-room` | Run the ADR-151 room pipeline |
+| `ruview.room.watch` | `wifi-densepose room-watch` | Live presence/vitals from a trained room |
+| `ruview.verify` | `scripts/generate-witness-bundle.sh` + `verify.py` | Produce/verify the witness bundle (must be N/N PASS) |
+| `ruview.claim.check` | static lint | Scan output for untagged accuracy claims; flag MEASURED-vs-CLAIMED |
+
+Each tool returns structured JSON and is fail-closed: a tool that cannot prove its
+result (e.g. `ruview.node.monitor` sees no CSI callbacks) returns an honest negative,
+never a fabricated success — consistent with the RuField `map_privacy` fail-closed
+posture (ADR-262 §3.3).
+
+### The mint + pin flow (how the harness is produced)
+
+```bash
+# P1 — mint from this repo, claude-code host, RuView vertical
+npx metaharness ruview --template vertical:ruview --host claude-code \
+  --from-existing . --description "RuView WiFi-sensing operator agent" \
+  --target ./harness/ruview
+
+# readiness + fit/cost/safety scorecards (ADR-041) — gate before publish
+npx metaharness genome .        # 7-section repo readiness
+npx metaharness score .  --json # fit / cost / safety
+npx metaharness analyze .       # recommended harness plan (no-exec)
+```
+
+The minted harness is committed under `harness/ruview/` and **pinned** (kernel +
+host-adapter + router versions locked) so `npx ruview` is reproducible. Re-minting on
+a CLI/ADR change is a reviewed PR, not an implicit regeneration.
+
+### Distribution: `npx ruview`
+
+A small published package whose `bin` boots the pinned harness via the kernel:
+
+- **Preferred name:** `ruview` (currently **free** on npm — verified 2026-06-17).
+- **Risk:** npm's typosquat filter may reject `ruview` as too close to `review` /
+  `preview` (this session hit exactly that on `ruvn`→`levn`/`raven` and
+  `worldgraph`→`world-graph`). **Fallback:** publish scoped `@ruvnet/ruview` (also
+  free) and/or `npx ruvnet/ruview` straight from GitHub. Decide at publish time;
+  do not unpublish to rename (the 24-h name-lock lesson from `worldgraphs`).
+- `bin: { "ruview": "bin/cli.js" }` — note **`bin/cli.js`, not `./bin/cli.js`** (npm
+  strips the `./` form; this broke `ruvn@0.1.0` this session).
+- `npx ruview` with no args → `onboard` skill (interactive path picker).
+  `npx ruview <skill> [...]` → run a specific skill. `npx ruview --host codex` →
+  install the harness into an existing repo for that host.
+

+
+Provenance: the harness ships an **ed25519 witness + SBOM (SPDX) + SLSA** chain
+(MetaHarness already does this for minted harnesses), so a recipient can verify the
+RuView harness was built from a specific monorepo commit — the agentic analogue of
+the firmware witness bundle (ADR-028).
+
+## Phases
+
+- **P1 — Mint & pin (claude-code).** `npx metaharness ruview --template
+  vertical:ruview --from-existing . --host claude-code`. Port the three `ruview-*`
+  subagents into host-neutral genome skills. Commit under `harness/ruview/`, pin
+  versions. Acceptance: `npx metaharness score .` ≥ threshold; the harness can run
+  `onboard` and `verify` end-to-end locally.
+- **P2 — MCP tool surface.** Implement the `ruview.*` MCP tools over the kernel
+  (start with `onboard`, `verify`, `claim.check`, `node.monitor` — the read-only /
+  proving tools), then the mutating ones (`node.flash`, `provision`, `calibrate`).
+  Acceptance: `ruview.verify` returns the witness bundle PASS as structured JSON;
+  `ruview.claim.check` flags a seeded untagged "100% accuracy" string.
+- **P3 — Publish `npx ruview` + multi-host.** Publish the bin package (name decision
+  per Distribution). Add codex / opencode / copilot / pi-dev / hermes / rvm /
+  github-actions adapters. Acceptance: `npx ruview` cold-starts on ≥3 hosts and runs
+  `onboard`; provenance verifies.
+- **P4 — Router + guardrail hardening.** Wire `@metaharness/router`; calibrate the
+  3-tier routing on a RuView task set. Make the MEASURED-vs-CLAIMED guardrail a hard
+  pre-output gate. Acceptance: a benchmark of RuView tasks shows cost reduction vs
+  all-Opus with no quality regression; the guardrail blocks an untagged accuracy
+  claim in a red-team prompt.
+
+## Consequences
+
+**Positive**
+- One reproducible, signed entry point (`npx ruview`) that operates RuView on the
+  host the user already has — onboarding goes from "clone a 15-crate monorepo" to a
+  single `npx`.
+- The "prove everything" ethos becomes **executable**, not just documentation: the
+  harness *enforces* MEASURED-vs-CLAIMED and the mean-pose baseline.
+- Knowledge written once (host-neutral genome) instead of 9× per host; regenerable
+  from the repo as the system evolves.
+- Dogfoods MetaHarness on a hard real vertical, surfacing bugs back to
+  `agent-harness-generator` (this session already filed #9–#13 there).
+
+**Negative / risks**
+- **Drift:** a pinned harness goes stale as the CLI/ADRs move; mitigated by a
+  re-mint-on-change PR ritual and a CI check that the genome's referenced
+  CLI flags still exist.
+- **Surface area:** mutating MCP tools (`node.flash`, `provision`) touch hardware and
+  the network — must be permission-gated and fail-closed; the firmware-flash tool
+  must never claim hardware validation without a captured boot log.
+- **Name/typosquat:** `ruview` may be rejected at publish; scoped fallback decided in
+  P3. Do not unpublish-to-rename.
+- **Host parity:** not all 9 hosts support MCP + hooks equally; the guardrail gate
+  may degrade to advisory on weaker hosts — must be disclosed in the badge, not
+  hidden (same honesty principle as ADR-181's backend badge).
+- **Windows-coupled tooling:** the ESP-IDF flow is Windows-subprocess-specific
+  today; the `node.*` tools are gated to that environment until a cross-platform
+  path exists.
+
+## Alternatives considered
+
+1. **Keep the `ruview-*` subagents repo-local (status quo).** Zero new surface, but
+   stays Claude-Code-only and clone-gated; no portable front door. Rejected — it's
+   the gap this ADR exists to close.
+2. **Hand-write a bespoke `npx ruview` harness (no MetaHarness).** Full control, but
+   re-implements the kernel, 9 host adapters, the router, and the provenance chain
+   we already ship — months of duplicated work and 9 divergent configs to maintain.
+   Rejected.
+3. **Use the generic `vertical:ruview` template as-is.** It's scaffolding with no
+   real tools or guardrails — it would *talk about* RuView without being able to
+   *operate* it or enforce honesty. Rejected as insufficient; P2 is precisely the
+   hardening that makes it real.
+4. **Ship only an MCP server (no harness/host adapters).** Covers tools but not the
+   skills, routing, guardrails, or multi-host projection — a strictly smaller subset
+   of this design. Folded in as the P2 layer rather than the whole.
+
+## Open questions
+
+- Final published name: bare `ruview` vs scoped `@ruvnet/ruview` vs GitHub-only

+# ADR-183: Onboard LED as a 40 Hz Gamma Stimulus, Colour-Mapped from Live CSI via `ruv-neural-viz`
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — implemented & hardware-confirmed on ESP32-S3 N16R8 (COM8) |
+| **Date** | 2026-06-17 |
+| **Deciders** | ruv |
+| **Codename** | **GAMMA-VIZ** |
+| **Builds on** | `ruv-neural-viz::ColorMap` (now `no_std` — ruvnet/ruv-neural#3 / RuView#1126), the ESP32 edge `motion_energy` metric (`edge_processing.c`), PR #962 (WS2812 on GPIO 48) |
+
+## Context
+
+Two threads converged. (1) `ruv-neural-viz::ColorMap` — the viridis/cool-warm
+palette the rUv-Neural stack uses to render brain-topology graphs — was `std`-only,
+so it couldn't run on the ESP32. (2) The onboard WS2812 on the S3 CSI node was dead
+weight: the firmware only cleared it on boot (and on the wrong pin for N16R8 — GPIO
+38 vs the actual 48, see #962).
+
+The ask: make the LED do something real and honest, using the project's own visual
+capability — not a decorative blink. The natural fit is a **40 Hz gamma stimulus**
+(the GENUS gamma-entrainment frequency from Alzheimer's light-therapy research)
+whose **colour is driven by live sensed motion**, so the node's front panel is both
+a known bio-stimulus waveform and a truthful readout of what the CSI is detecting.
+
+## Decision
+
+### Part A — make `ColorMap` `no_std`
+
+`colormap.rs` is self-contained (no cross-crate deps), so expose it on `no_std`
+targets. The only blockers were two `std`-only `f64` ops:
+
+- `f64::round` / `f64::abs` → replaced with `core`+`alloc`-safe helpers `fround`
+  (round via `f64 as i64` truncation — a `core` cast, no `libm`) and `fabs`.
+- `Vec`/`String`/`format!` → from `alloc`.
+
+The graph-bound modules (`animation`/`ascii`/`export`/`layout`) and their heavy deps
+move behind a default `std` feature; `--no-default-features` builds the crate `no_std`
+and exposes only `colormap`. Output is **byte-identical** (8/8 colormap tests pass with
+the same RGB values), so this is a pure portability change.
+
+### Part B — the LED stimulus (firmware)
+
+`firmware/esp32-csi-node/main/main.c`, on boot:
+
+- WS2812 on **GPIO 48** (N16R8 / DevKitC-1 v1.1; GPIO 8 on C6).
+- An `esp_timer` periodic at **12 500 µs toggles a square wave → 40 Hz, 50 % duty**
+  (full-on / full-off — a *perceptible* gamma flicker, not a colour drift).
+- **ON-phase colour = live CSI motion.** Each ON phase reads `edge_get_vitals().motion_energy`,
+  normalises it (`/ LED_MOTION_FULLSCALE`, clamped `[0,1]`), and indexes a **60-step
+  viridis LUT generated from `ColorMap::viridis().map()`** — still = dark purple,
+  strong motion = yellow.
+
+The LUT is baked from the real crate (Part A makes the same `ColorMap` embeddable
+for a future direct FFI path once the ESP Rust toolchain is in CI). The colours are
+therefore provably `ruv-neural-viz`'s, and the motion is provably real.
+
+## Honesty (what it is and is not)
+
+- **40 Hz is a real square-wave stimulus** (12.5 ms on / 12.5 ms off), not a label on
+  a colour sweep. It is *not* tied to any measured 40 Hz brain rhythm — it is an
+  *output* stimulus at the gamma frequency, not a readout of neural gamma.
+- **Colour is a real CSI readout** — `motion_energy` is the on-device phase-variance
+  motion metric the node already computes; no fabrication. At rest the LED sits at the
+  purple (low) end and flickers there.
+- No therapeutic claim is made. 40 Hz GENUS entrainment is cited as the *origin of the
+  frequency choice*, not as a validated medical effect of this device.
+
+## Consequences
+
+**Positive**
+- The LED is now an honest front-panel: gamma-frequency flicker + a live motion readout.
+- `ColorMap` is embeddable (`no_std`), unblocking on-device use of the rUv-Neural
+  palette beyond this LED.
+- Confirms #962's GPIO-48 fix visually (the LED lights on N16R8).
+
+**Negative / risks**
+- Changes the *default* firmware behaviour: the onboard LED animates instead of staying
+  off. Now **gated by `CONFIG_LED_GAMMA_VIZ`** (default `y`); set it `n` for a dark,
+  lower-power boot (the LED is just cleared) — no source change needed.
+- A 40 Hz flicker can be an issue for photosensitive users; document on the enclosure
+  and disable `CONFIG_LED_GAMMA_VIZ` in those deployments.
+- The saturation point is now `CONFIG_LED_MOTION_FULLSCALE_MILLI` (default 250 = 0.25),
+  operator-tunable; still not auto-calibrated per-environment.
+- The colour uses a baked LUT, not the live Rust `ColorMap` (FFI path deferred — needs
+  the ESP Rust/xtensa toolchain, not yet in CI).
+
+## Validation
+
+- `ruv-neural-viz`: `cargo build` (std) ✓, `cargo test colormap` 8/8 ✓ (identical RGB),
+  `cargo build --no-default-features` compiles `no_std` ✓.
+- Firmware: built (1.13 MB), flashed to ESP32-S3 N16R8 (COM8). Boot log:
+  `Onboard WS2812: 40 Hz gamma flicker (GENUS), colour=CSI motion via ruv-neural-viz, GPIO 48`;
+  CSI continues (27–38 pps), `motion=0.00` at rest → purple flicker as designed.
+- Full on-device (xtensa) Rust build of `ColorMap` not run — ESP Rust toolchain absent.

+
+| Field | Value |

+| **Status** | Proposed |
+| **Date** | 2026-07-21 |
+| **Deciders** | ruv |
+| **Codename** | **PHOENIX-LANDING** — the PIP-PHOENIX wheel that never actually took off |
+| **Relates to** | [ADR-117](ADR-117-pip-wifi-densepose-modernization.md) (PIP-PHOENIX modernization — this ADR completes it), [ADR-028](ADR-028-esp32-capability-audit.md) (witness chain), [ADR-115](ADR-115-home-assistant-integration.md) (HA/Matter sibling), [ADR-168](ADR-168-benchmark-proof.md) (measured-not-claimed house style) |
+| **Tracking issue** | [#785](https://github.com/ruvnet/RuView/issues/785) (ADR-117, still OPEN) |
+
+---
+
+## 1. Context
+
+ADR-117 (PIP-PHOENIX) designed the v2.0.0 rewrite of the pip `wifi-densepose`
+package as a PyO3 + maturin compiled wheel over the Rust core, plus a `ruview`
+sibling package, replacing the 11.5-month-stale pure-Python `1.1.0` line. The
+code landed on `main` (the `python/` workspace: `Cargo.toml`, `src/bindings/*.rs`,
+the `wifi_densepose/` Python package, `tests/`, `bench/`). The tombstone shipped.
+**But the release itself is broken and the design doc's own P5 intent was never met.**
+
+This ADR is a **gap analysis and remediation plan**, not a new feature. Every fact
+below was verified against PyPI and GitHub Actions on 2026-07-21; none are projected.
+
+### 1.1 What is actually live on PyPI (measured)
+
+`pip index versions wifi-densepose` returns:
+
+```
+wifi-densepose (1.99.0)
+Available versions: 1.99.0, 1.2.0, 1.1.0, 1.0.0
+```
+
+- `1.99.0` — the tombstone wheel **is genuinely live**. `import wifi_densepose`
+  raises `ImportError` pointing users to 2.0+. This part of ADR-117 §7.2 shipped.
+- `2.0.0a1` — appears in PyPI's release history as a **pre-release** (hidden from
+  the default `pip index` view, surfaced with `--pre`). It is still an **alpha**.
+- `2.0.0` (stable) — **does not exist.** ADR-117's headline deliverable
+  (`pip install wifi-densepose==2.0.0`) is not installable.
+
+`pip index versions ruview` returns:
+
+```
+ERROR: No matching distribution found for ruview
+```
+
+The `ruview` sibling package **was never published.** Commit `b71d243b4`
+(*"feat(adr-117): publish wifi-densepose 2.0.0a1 + ruview 2.0.0a1 to PyPI"*) claims
+a publish that did not happen for that package — a real **claimed-vs-measured gap**
+of exactly the kind [ADR-168](ADR-168-benchmark-proof.md) and the project's
+"prove everything" posture exist to catch.
+
+### 1.2 Why the release pipeline was stuck (measured; interim-fixed — see §1.4)
+
+`gh run list --workflow pip-release` shows the last **4** runs all
+`conclusion=failure` (most recent `2026-05-24T16:34`). The full failure log for
+run `26366735779` (job *"Publish v1.99 tombstone"* → step *"Publish to PyPI"*)
+shows two things:
+
+1. The publish step uses `pypa/gh-action-pypi-publish` with a `password`
+   (API-token) input and fails:
+
+   ```
+   403 Forbidden — Invalid or non-existent authentication information.
+   ```
+
+   i.e. the `PYPI_API_TOKEN` GitHub secret is stale / expired / revoked.
+
+2. The action's own log warns:
+
+   ```
+   Warning: the workflow was run with 'attestations: true' ... but an explicit
+   password was also set, disabling Trusted Publishing.
+   ```
+
+The workflow at `.github/workflows/pip-release.yml` wires `password:
+${{ secrets.PYPI_API_TOKEN }}` into **four** publish steps (lines 249, 258, 282,
+291) and declares only `permissions: contents: read` (line 49–50). So it is using a
+rotatable, leak-able, expire-able API token in exactly the place ADR-117 §5.4 / §5.5
+and the issue #785 P5 row explicitly called for **OIDC Trusted Publishing** ("cp310
+… abi3-py310, OIDC"; ADR-117 §5.5 line 547: *"PyPI publish via Trusted Publisher
+(OIDC, no API token in secrets)"*). **The implementation drifted from its own
+design doc.**
+
+### 1.3 Why the package is still alpha (measured)
+
+`python/pyproject.toml` pins `version = "2.0.0a1"` (line 13) and
+`Development Status :: 3 - Alpha` (line 26). Issue #785's closing criteria
+(§"Done") require `wifi-densepose==2.0.0` (**not** alpha) published, plus all 10
+acceptance criteria in §11. None of those can be true today given §1.1–§1.2.
+
+**Why this matters:** ADR-117 is the sole Python entry point for the whole RuView
+ecosystem (per its §2 "PyPI org presence check"). A stale token silently blocking
+every release means the entire "plug-and-play Python entry point for the pip +
+Jupyter customer base" thesis (issue #785 "Strategic alignment") is stalled behind a
+one-line credential problem — and a commit message claims otherwise.
+
+### 1.4 Interim fix applied (2026-07-21) — credential unblocked, migration still pending
+
+**As of 2026-07-21T22:57:29Z the stale-credential symptom is fixed at the credential
+layer.** The maintainer fetched a valid `PYPI_TOKEN` from GCP Secret Manager (project
+`cognitum-20260110`) and ran `gh secret set PYPI_API_TOKEN` to replace the
+revoked/expired value. Authentication was confirmed non-destructively via a
+`twine upload --skip-existing` re-upload of the existing `1.99.0` tombstone artifacts,
+which returned a benign 400/skip response (not the previous `403 Forbidden`) — proving
+the new token authenticates correctly.
+
+This means **token-based publishing works again today** — the `403` root cause
+described in §1.2 no longer reproduces. It does **not**, however, close this ADR:
+
+- A **manually-rotated token still expires, leaks, and can be revoked over time** — it
+  re-introduces exactly the silent-failure mode that blocked the last 4 runs. It is a
+  stopgap at the same layer as the §3.2 fallback, not the durable fix.
+- The OIDC **Trusted Publishing migration (§3, P1) remains the decision** — a
+  credential PyPI mints per-run with no secret to rotate is the only fix that removes
+  the recurring-expiry class of failure.
+- The other three gaps are **untouched** by this rotation: `wifi-densepose` is still
+  `2.0.0a1` (not stable `2.0.0`), and `ruview` is still unpublished.
+
+**Why/How to apply:** read §1.2's "root cause" as *diagnosed and temporarily
+mitigated*, not *still broken*. A reviewer re-running the §7.5 check today may now see
+a green token-based run — that is expected and does not satisfy this ADR, which is
+Accepted only when §6's criteria pass **and** the workflow no longer carries a static
+token (§7.4).

+
+**Why/How to apply:** treat this table as the falsifiable baseline. A reviewer who
+re-runs each `Source` command must reproduce each `Value`, or this ADR is wrong and
+should be revised before any remediation is attempted.
+
+---
+
+## 3. Decision
+
+Complete ADR-117 by closing four gaps, in order:
+
+1. **Migrate `pip-release.yml` to PyPI Trusted Publishing (OIDC)** — as the durable
+   end-state, drop all four `password: ${{ secrets.PYPI_API_TOKEN }}` inputs, grant
+   `id-token: write` to the publish jobs, and add `environment: pypi`. This removes
+   the rotatable/expire-able credential and realigns with ADR-117 §5.5's stated OIDC
+   intent. **This is gated behind sub-phase P1b** (§5): the switch is inert — and in
+   fact 403-breaking — until the manual pypi.org registration (§3.1) exists, so the
+   OIDC change must land *together* with that registration. Until then, token auth
+   (the freshly-rotated `PYPI_API_TOKEN`, §1.4) is the correct active path and is
+   what the `RuView#786-pypi-token-auth` fix-marker guard enforces. An OIDC migration
+   was attempted (`cc153e8b5`) and reverted (`82d5c7339`) for exactly this reason.
+
+2. **Promote `wifi-densepose` from `2.0.0a1` to stable `2.0.0`** in
+   `python/pyproject.toml` (version + `Development Status :: 5 - Production/Stable`)
+   and record the promotion in `CHANGELOG.md`.
+
+3. **Actually publish `ruview==2.0.0`** — the sibling package that commit
+   `b71d243b4` claimed but never shipped — and verify it with `pip index versions`.
+
+4. **Adopt issue #785 §11's 10 acceptance criteria verbatim as this ADR's own
+   acceptance criteria** (§6 below), and only flip ADR-117 → Accepted and close
+   #785 once every one passes against the real index — proven, not claimed.
+
+### 3.1 Mandatory human prerequisite (cannot be automated)
+
+**Trusted Publishing requires a one-time manual step on `pypi.org` that no CLI, API,
+or agent can perform** — PyPI restricts Trusted Publisher configuration to the
+project owner via the web UI for security reasons. Before P1's workflow change can
+succeed, a human with owner rights on both PyPI projects must:
+
+1. Log in to `pypi.org`.
+2. For **`wifi-densepose`**: Project → *Publishing* → *Add a new pending/trusted
+   publisher* → GitHub, with:
+   - Owner: `ruvnet`
+   - Repository: `RuView`
+   - Workflow filename: `pip-release.yml`
+   - Environment: `pypi`
+3. Repeat the identical step for the **`ruview`** project. Because `ruview` is not
+   yet on PyPI, register it as a **pending publisher** (PyPI supports configuring a
+   trusted publisher for a project name before its first release — the first OIDC
+   publish then creates the project).
+
+**Why/How to apply:** the workflow change in P1 is inert until this is done — the
+publish step will fail with a "no trusted publisher configured" error rather than a
+403. Land P1 and this manual step together; do not tag a release expecting OIDC to
+work until a human confirms both entries exist. Treat this section as a blocking
+checklist item on the release-day runbook, not a footnote.
+
+### 3.2 Fallback path (if the owner declines Trusted Publishing)
+
+If the maintainer prefers not to adopt OIDC yet, the code-side remediation is a
+**token regeneration**, not a redesign:
+
+- Generate a fresh PyPI API token (scoped to the `wifi-densepose` and `ruview`
+  projects) and store it in GCP Secret Manager (project `cognitum-20260110`, where
+  the project's tokens live), then `gh secret set PYPI_API_TOKEN` from it, following
+  the existing runbook referenced in the workflow header (`docs/integrations/pypi-release.md`).
+- Keep the current `password:`-based workflow unchanged.
+
+**Why/How to apply:** this path clears the 403 and unblocks releases immediately,
+but it re-introduces the exact failure mode this ADR is trying to eliminate — a
+credential that silently expires and blocks the whole Python entry point again. Use
+it only as a stopgap; the Trusted Publishing migration (P1) is the durable fix and
+should remain the default recommendation.
+
+---
+
+## 4. Detailed design — workflow migration
+
+The change to `.github/workflows/pip-release.yml` is small and surgical. It does
+**not** touch the build matrix (`build-wheels`, `build-sdist`, `build-tombstone`
+jobs are unchanged — the 403 is a publish-credential problem, not a build problem).
+
+### 4.1 Grant OIDC token permission on the publish jobs
+
+The `gh-action-pypi-publish` action mints its OIDC token from the job's
+`id-token: write` permission. The current top-level `permissions: contents: read`
+must be extended on the two publish jobs (`publish-v2`, `publish-tombstone`) — plus
+the future `publish-ruview` job:
+
+```yaml
+publish-v2:
+  name: Publish v2 wheels
+  needs: [build-wheels, build-sdist]
+  permissions:
+    id-token: write        # ← added: mint the OIDC token for PyPI
+    contents: read
+  environment: pypi         # ← added: binds to the PyPI trusted-publisher entry
+```
+
+### 4.2 Drop the `password:` inputs
+
+Every publish step loses its `password:` line. Trusted Publishing needs no secret —
+the action exchanges the job's OIDC token for a short-lived PyPI upload token
+automatically:
+
+```yaml
+# BEFORE (current — fails with 403 when the token is stale)
+- name: Publish to PyPI
+  uses: pypa/gh-action-pypi-publish@release/v1
+  with:
+    password: ${{ secrets.PYPI_API_TOKEN }}   # ← remove
+    packages-dir: dist
+
+# AFTER (Trusted Publishing — no secret, activates once the pypi.org entry exists)
+- name: Publish to PyPI
+  uses: pypa/gh-action-pypi-publish@release/v1
+  with:
+    packages-dir: dist
+```
+
+The TestPyPI dry-run steps keep `repository-url: https://test.pypi.org/legacy/` and
+likewise drop `password:` — a matching trusted-publisher entry must be registered on
+`test.pypi.org` if the dry-run path is to be used (otherwise gate the dry-run behind
+the fallback token or remove it).
+
+**Why/How to apply:** the header comment block (lines 16–23) that documents the
+`PYPI_API_TOKEN` / GCP-Secret-Manager runbook must be rewritten to document the
+Trusted Publishing setup instead, so the next maintainer does not re-add a token
+"to fix" a future failure and silently re-disable OIDC.
+
+### 4.3 Add the `publish-ruview` job
+
+`ruview` is published by a new job mirroring `publish-v2` (same `id-token: write` +
+`environment: pypi`, no `password:`), gated on a `ruview`-scoped build. Because the
+package has never shipped, its first successful OIDC publish creates the PyPI
+project against the pending trusted-publisher entry from §3.1.
+
+---
+
+## 5. Phase ledger
+
+```
+P1  ──►  P1b  ──►  P2  ──►  P3  ──►  P4
+token    OIDC      version   real     close
+unblock  (gated)   promote   publish  #785
+```
+
+### P1 — Credential unblock (token auth, active)
+
+- [x] Rotate `PYPI_API_TOKEN` to a validated token (§1.4, `gh secret set`, verified
+  `2026-07-21T22:57:29Z` via `twine upload --skip-existing`). Token-based publishing
+  works today.
+- [x] Keep `password: ${{ secrets.PYPI_API_TOKEN }}` as the active auth path,
+  satisfying the `RuView#786-pypi-token-auth` fix-marker guard.
+- [ ] Rewrite the `pip-release.yml` header comment block so the next maintainer
+  knows OIDC is the intended P1b end-state (not a token to keep re-rotating forever).
+
+> Note: an OIDC migration was attempted (`cc153e8b5`) and **reverted** (`82d5c7339`)
+> because it tripped the fix-marker guard before the pypi.org registration existed.
+> The OIDC work is therefore tracked as P1b below, not P1. See the Status note.
+
+**Status 2026-07-21 — DESIGNED then REVERTED (token auth is the ACTIVE path):**
+The OIDC migration was implemented (commit `cc153e8b5` — `id-token: write` +
+`environment: pypi` on both publish jobs, all four `PYPI_API_TOKEN` password
+inputs removed) but then **reverted** (commit `82d5c7339`) after it tripped the
+pre-existing `RuView#786-pypi-token-auth` fix-marker guard
+(`scripts/fix-markers.json`). That guard `require`s
+`password: ${{ secrets.PYPI_API_TOKEN }}` and `forbid`s `id-token: write`
+precisely because a half-activated OIDC path (id-token permission present, but no
+Trusted Publisher yet registered on pypi.org) leaves publishing **403-broken**
+rather than working — it correctly predicted this exact failure. The revert was
+verified locally against the real checker (`python scripts/check_fix_markers.py` →
+all 25 markers pass, exit 0) before pushing.
+
+**Active path today:** token-based auth via the freshly-rotated `PYPI_API_TOKEN`
+(§1.4). The current `pip-release.yml` (HEAD `82d5c7339`) carries
+`password: ${{ secrets.PYPI_API_TOKEN }}` at four publish steps plus a TODO
+comment marking the OIDC follow-up. The OIDC switch is therefore **not** done — it
+moves to sub-phase P1b below.
+
+**Why this revert was correct (measured, not claimed):** OIDC is the better
+long-term design and matches ADR-117's original §5.5 P5 intent — but implementing
+it *before* the manual pypi.org registration exists would have shipped a workflow
+that looks migrated yet 403s on the next real publish. The fix-marker caught a
+well-intentioned improvement that wasn't the honest, currently-working state, and
+it was reverted rather than overridden. That is the same "measured not claimed"
+discipline (per [ADR-168](ADR-168-benchmark-proof.md)) this entire ADR exists to
+enforce — applied here to our own change.
+
+### P1b — Switch to OIDC Trusted Publishing (gated follow-up)
+
+- [ ] **(human, manual, pypi.org — BLOCKING)** Complete the §3.1 Trusted Publisher
+  registration for BOTH `wifi-densepose` and `ruview` (owner=ruvnet, repo=RuView,
+  workflow=pip-release.yml, environment=pypi). P1b must not start until this exists.
+- [ ] Re-apply the `cc153e8b5` change (add `id-token: write` + `environment: pypi`,
+  drop the four `password:` inputs) as its own follow-up commit.
+- [ ] Update the `RuView#786-pypi-token-auth` fix-marker in `scripts/fix-markers.json`
+  in the *same* commit — invert it to `require: id-token: write` / `forbid:
+  password: ${{ secrets.PYPI_API_TOKEN }}` — so the guard tracks the new intended
+  state instead of blocking it (referencing the TODO comment now in pip-release.yml).
+- [ ] Confirm a green OIDC publish before removing the token, per §3.2's
+  keep-both-paths recommendation (OIDC first, token fallback until OIDC is proven).
+- [ ] No capability gap: publishing must keep working across the P1→P1b transition.
+
+### P2 — Version promotion + changelog
+
+- [ ] `python/pyproject.toml`: `version = "2.0.0"` (drop the `a1` suffix).
+- [ ] `python/pyproject.toml`: `Development Status :: 5 - Production/Stable`.
+- [ ] `CHANGELOG.md`: `[Unreleased]` entry — "wifi-densepose 2.0.0 promoted from
+  alpha; ruview 2.0.0 first stable publish; pip-release migrated to Trusted Publishing".
+- [ ] Confirm the `ruview` package's own version metadata is set to `2.0.0`.
+
+### P3 — Real publish + verification
+
+- [ ] Cut tag `v2.0.0-pip` (per the workflow's `v*-pip` trigger) → OIDC publish of
+  the `wifi-densepose` wheel matrix.
+- [ ] Publish `ruview==2.0.0` via the new `publish-ruview` job.
+- [ ] Run every command in §7 against the **real** PyPI index and capture output.
+- [ ] Generate + commit `expected_features_v2.sha256` (issue #785 §11 criterion 10),
+  resolving ADR-117 §11.3 / the workflow header's Q3 note.
+
+### P4 — Close issue #785
+
+- [ ] All 10 acceptance criteria (§6) pass against the real index.
+- [ ] Flip ADR-117 §Status → **Accepted**.
+- [ ] Flip this ADR (ADR-184) §Status → **Accepted**.
+- [ ] Close issue #785.
+
+**Why/How to apply:** the phases are strictly ordered — P3 cannot succeed until both
+P1 (working credential path) and the §3.1 human step are done, and P4 must not be
+marked complete on the strength of a commit message (the failure mode this ADR
+exists to correct). Nothing in this ledger is checked; this is a Proposed plan.
+
+---
+
+## 6. Acceptance criteria (verbatim from issue #785 §11)
+
+A reviewer must be able to:
+
+1. `pip install --pre wifi-densepose==2.0.0a1` from PyPI test index → wheel installs
+   without compile step on Linux/macOS/Windows
+2. `python -c "import wifi_densepose; print(wifi_densepose.__version__, wifi_densepose.__rust_version__)"`
+   → both versions print
+3. `python -c "from wifi_densepose import CsiFrame; ..."` → core type round-trips
+   through PyO3
+4. `python -c "from wifi_densepose import vitals; vitals.detect_hr(...)"` → 4-stage
+   pipeline runs on a sample CSI buffer
+5. `pip install wifi-densepose[client]; python -c "import wifi_densepose.client; ..."`
+   → WS client connects to a running sensing-server
+6. `pytest python/tests/` → ≥30 tests pass (smoke + binding round-trips)
+7. `maturin build --release --strip` → wheel under 5 MB per platform (ADR §5.4 budget)
+8. `wifi-densepose==1.99.0` is the latest 1.x; `import wifi_densepose` raises
+   `ImportError` with migration URL
+9. `wifi-densepose==1.0.0` is yanked from PyPI; `1.1.0` is un-yanked with deprecation
+   notice (90-day window)
+10. Witness `expected_features_v2.sha256` generated in CI, committed alongside the
+    existing `archive/v1/data/proof/`, re-verifiable from Python via
+    `wifi_densepose.verify_witness(...)`
+
+**Note (amendment to criterion 1):** issue #785 §11 was written when `2.0.0a1` was
+the target. This ADR promotes to stable `2.0.0`, so criterion 1 is read as
+`pip install wifi-densepose==2.0.0` (no `--pre`) against the production index. The
+`--pre`/`a1` wording is preserved verbatim above per the transcription requirement;
+the stable form is what P3/P4 must actually satisfy. This ADR additionally requires
+`ruview==2.0.0` to be installable (the sibling package from commit `b71d243b4`),
+which #785 §11 did not enumerate but the issue "Done" section implies.
+
+---
+
+## 7. How to verify (prove, don't claim)
+
+Exact commands a reviewer runs to prove — not assume — each gap is closed. Every one
+produces falsifiable output; capture it in the PR that flips ADR-117 to Accepted.
+
+### 7.1 Both packages live and stable
+
+```bash
+# wifi-densepose 2.0.0 (stable, NOT alpha) must appear
+pip index versions wifi-densepose
+#   expect: "wifi-densepose (2.0.0)" and 2.0.0 in the available list
+
+# ruview 2.0.0 must now exist (currently: "No matching distribution found")
+pip index versions ruview
+#   expect: "ruview (2.0.0)"
+```
+
+### 7.2 Clean-venv install + import (criteria 2–4)
+
+```bash
+python -m venv /tmp/verify-184 && . /tmp/verify-184/bin/activate
+pip install wifi-densepose==2.0.0        # stable, no --pre
+python -c "import wifi_densepose; print(wifi_densepose.__version__, wifi_densepose.__rust_version__)"
+python -c "from wifi_densepose import CsiFrame; print(CsiFrame([1.0]*56,[0.0]*56,56,0,100.0))"
+python -c "from wifi_densepose import vitals; print(hasattr(vitals,'detect_hr'))"
+pip install ruview==2.0.0
+python -c "import ruview; print(ruview.__version__)"
+```
+
+### 7.3 Tombstone still guards the 1.x line (criterion 8)
+
+```bash
+pip install wifi-densepose==1.99.0
+python -c "import wifi_densepose" 2>&1 | grep -q "github.com/ruvnet/RuView" \
+  && echo "PASS: tombstone raises with migration URL" \
+  || echo "FAIL"
+```
+
+### 7.4 Workflow auth state
+
+**Current state (P1, active today):** token auth is the working path and is what
+the `RuView#786-pypi-token-auth` fix-marker requires. The honest check today is
+that token auth is present and the fix-marker guard passes:
+
+```bash
+# token auth present (the ACTIVE, working path — expected PASS today)
+grep -q 'password: ${{ secrets.PYPI_API_TOKEN }}' .github/workflows/pip-release.yml \
+  && echo "PASS: token auth active" || echo "FAIL"
+
+# fix-marker regression guard must pass
+python scripts/check_fix_markers.py && echo "PASS: all markers pass"
+```
+
+**P1b end-state (after the manual pypi.org registration):** the checks below flip
+to PASS *only once P1b lands together with the fix-marker inversion* — they are
+**not** expected to pass today and their passing now would mean a half-migrated,
+403-prone workflow:
+
+```bash
+# after P1b: no static token should remain in the publish steps
+grep -nE 'password:|PYPI_API_TOKEN' .github/workflows/pip-release.yml \
+  && echo "not yet: token still present (expected during P1)" \
+  || echo "P1b done: no static token"
+
+# after P1b: id-token permission granted on publish jobs
+grep -q 'id-token: write' .github/workflows/pip-release.yml \
+  && echo "P1b done: OIDC permission present" \
+  || echo "not yet: OIDC not enabled (expected during P1)"
+```
+
+### 7.5 The release actually went green
+
+```bash
+gh run list --workflow pip-release --limit 1
+#   expect: conclusion=success on the v2.0.0-pip tag run
+```
+
+**Why/How to apply:** §7.1 and §7.5 together are the minimal proof that the two
+headline gaps (no stable 2.0.0, no `ruview`, dead pipeline) are closed. If any
+command's actual output diverges from the `expect` line, the corresponding phase is
+not done — regardless of what any commit message or checkbox says.
+
+---
+
+## 8. Consequences
+
+### Positive
+
+- The Python entry point for the entire RuView ecosystem (issue #785 "Strategic
+  alignment") is unblocked with a credential that cannot silently expire.
+- The claimed-vs-measured gap in commit `b71d243b4` (`ruview` never published) is
+  closed with reproducible proof, upholding the project's "prove everything" posture.
+- Trusted Publishing removes a leak-able long-lived secret from CI entirely — the
+  security posture ADR-117 §5.5 originally specified.
+- ADR-117 / issue #785 can finally reach a defensible Accepted/closed state instead
+  of sitting open behind a one-line token failure.
+
+### Negative
+
+- The `pypi.org` trusted-publisher registration (§3.1) is a hard human dependency
+  with no automated fallback beyond re-introducing a token (§3.2). Release day is
+  blocked on a person, not a pipeline.
+- Promoting to stable `2.0.0` removes the alpha escape hatch — any binding bug now
+  ships under a stable version and needs a `2.0.1`, not a new `a`-tag.
+- `test.pypi.org` needs its own trusted-publisher entry if the dry-run path is kept,
+  adding a second manual registration.
+
+### Neutral
+
+- The build matrix (`build-wheels`, `build-sdist`, `build-tombstone`) is untouched;
+  the risk surface of this change is confined to the three publish jobs.
+- The witness-hash-v2 open question (ADR-117 §11.3, workflow header Q3) is pulled
+  into scope as criterion 10 but is orthogonal to the credential migration.

+| **Tracking issue** | TBD — file under RuView issue tracker |
+
+---
+
+## 1. Context
+
+### 1.1 Where ADR-117 stopped
+
+ADR-117 (PIP-PHOENIX) shipped the `wifi-densepose` v2.x PyPI wheel as a PyO3 +
+maturin compiled extension (`wifi_densepose._native`) with a pure-Python facade.
+The bound surface today (`python/src/bindings/*.rs`, `python/src/lib.rs`):
+
+| Bound today | Crate | Kind |
+|---|---|---|
+| `CsiFrame`, `Keypoint`, `KeypointType`, `BoundingBox`, `PersonPose`, `PoseEstimate` | `wifi-densepose-core` | P2 core types |
+| 4-stage vitals (`BreathingExtractor`, `HeartRateExtractor`, `VitalEstimate`, `VitalReading`, `VitalStatus`) | `wifi-densepose-vitals` | P3 DSP |
+| `BfldFrame`, `BfldReport`, `BfldKind` + `PrivacyClass` gate | `wifi-densepose-bfld` | P3.5 / ADR-118 |
+| `SensingClient` (WS), `RuViewMqttClient` (MQTT), HA helpers | pure-Python `wifi_densepose.client` | P4 `[client]` extra |
+
+ADR-117's own phase ledger (§6, "P6+ — Deferred") explicitly parked three
+higher-value subsystems as post-v2.0.0 work:
+
+> - [ ] `wifi-densepose-nn` bindings … · `wifi-densepose-ruvector` bindings …
+> - [ ] MQTT/Matter integration helpers …
+
+and ADR-117 §5.1 deferred `wifi-densepose-mat` (depends on nn) and the RuVector
+tier for wheel-size reasons. The three SOTA subsystems that a Python researcher
+most wants — re-identification embeddings, cross-environment transfer, and the
+disaster-triage tool — are precisely the ones still unreachable from
+`pip install wifi-densepose`.
+
+### 1.2 The three subsystems already exist and are tested in Rust
+
+None of this is new research. Each subsystem is a shipped, tested Rust module:
+
+| Subsystem | ADR | Rust location (verified HEAD) | Nature |
+|---|---|---|---|
+| **AETHER** — contrastive CSI embedding / re-identification | ADR-024 | `wifi-densepose-sensing-server/src/embedding.rs` (`EmbeddingExtractor`, `ProjectionHead`, `CsiAugmenter`, `AetherConfig`, `aether_loss`, `info_nce_loss`, `alignment_metric`, `uniformity_metric`) | Pure-sync DSP + linear algebra; 128-dim L2-normalized embeddings |
+| **MERIDIAN** — cross-environment domain generalization | ADR-027 | `wifi-densepose-train` (`domain::{DomainFactorizer, DomainClassifier, GradientReversalLayer, AdversarialSchedule}`, `geometry::{GeometryEncoder, FourierPositionalEncoding, FilmLayer, MeridianGeometryConfig}`, `rapid_adapt::{RapidAdaptation, AdaptationLoss}`, `virtual_aug::VirtualDomainAugmentor`, `eval::CrossDomainEvaluator`) + `wifi-densepose-signal::hardware_norm::{HardwareNormalizer, HardwareType, CanonicalCsiFrame}` | Inference/adaptation path is pure-Rust and **un-gated**; only `model`/`trainer`/`losses` need `tch-backend` (libtorch) |
+| **MAT** — Mass Casualty Assessment Tool | (root CLAUDE.md crate table) | `wifi-densepose-mat` (`DisasterResponse`, `DisasterConfig`, `DetectionPipeline`, `EnsembleClassifier`, `TriageCalculator`, `TriageStatus`, `Survivor`, `VitalSignsReading`) | Cargo-feature-gated (`mat`); sync ingest (`push_csi_data`) + async scan loop (`start_scanning`, tokio) |
+
+### 1.3 Why now, and why gated extras
+
+Two forces make P6 timely: (a) the v2.0.0 wheel is stable and its abi3-py310
+build matrix is proven, so adding modules is incremental; (b) integrators reading
+the ADR-115/ADR-117 notes are asking for Python access to re-identification and
+cross-room transfer specifically.
+
+But pulling all three into the **default** wheel would break ADR-117 §5.4's
+**≤ 5 MB per-platform wheel budget** and its "no heavy system deps" invariant:
+
+- MAT is already cargo-`mat`-gated upstream *because* it drags in the ML/detection
+  stack; the default wheel must not carry it.
+- MERIDIAN's training path (`model`/`trainer`/`losses`) is `tch-backend`-gated and
+  would pull libtorch (30 MB+), the exact wheel-size risk ADR-117 §5.1 flagged.
+
+So P6 mirrors the existing `[client]` extra pattern (ADR-117 §5.6): each subsystem
+becomes an **optional pip extra**, and the compiled surface is **feature-gated in
+`wifi-densepose-py`'s `Cargo.toml`** so the default wheel stays lean.
+
+### 1.4 What this ADR is *not*
+
+- Not a port of the Rust subsystems to Python — the Rust workspace stays
+  authoritative and unmodified, exactly as ADR-117 §1.3 established.
+- Not the `wifi-densepose-nn` / libtorch binding (still deferred; MERIDIAN binds
+  only the un-gated inference/adaptation path, not `tch-backend` training).
+- Not a change to the default wheel's contents, size budget, or abi3 base.
+
+---
+
+## 2. Gap analysis
+
+| Capability | Rust crate(s) | pip v2.x status | Gap severity |
+|---|---|---|---|
+| Extract a 128-dim re-ID embedding from a CSI window | `sensing-server::embedding` (AETHER) | Not present | **High** |
+| Compare two CSI observations by learned similarity (same room? same person?) | AETHER `EmbeddingExtractor` + cosine | Not present | **High** |
+| Hardware-invariant CSI normalization (ESP32 / Intel 5300 / Atheros → canonical 56) | `signal::hardware_norm` (MERIDIAN) | Not present | **High** |
+| Geometry-conditioned zero-shot deployment (AP positions → FiLM) | `train::geometry` (MERIDIAN) | Not present | **Medium** |
+| 10-second unlabeled few-shot room adaptation | `train::rapid_adapt` (MERIDIAN) | Not present | **Medium** |
+| Cross-domain evaluation protocol (in/cross/few-shot MPJPE) | `train::eval` (MERIDIAN) | Not present | **Medium** |
+| Disaster-survivor detection + START triage from CSI | `wifi-densepose-mat` | Not present | **Medium** (specialist audience) |
+
+---
+
+## 3. Decision
+
+Adopt **three new optional pip extras**, each binding one SOTA subsystem into the
+existing `wifi_densepose` wheel as a dedicated Python submodule, gated behind a
+matching Cargo feature so the default wheel is unchanged:
+
+```
+pip install wifi-densepose              # unchanged: core + vitals + bfld (≤5 MB)
+pip install wifi-densepose[aether]      # + wifi_densepose.aether
+pip install wifi-densepose[meridian]    # + wifi_densepose.meridian
+pip install wifi-densepose[mat]         # + wifi_densepose.mat   (mirrors upstream `mat` cargo feature)
+pip install wifi-densepose[sota]        # convenience: aether + meridian + mat
+```
+
+This path is called **PIP-TRINITY**. It reuses ADR-117's established idiom
+end-to-end: `#[pyclass]` newtype wrappers holding an `inner` Rust value, `#[new]`
+constructors, `#[getter]` accessors, `__repr__`, a per-module `register(m)` fn,
+and — critically — **GIL release via `py.allow_threads(|| …)` on every
+compute-heavy call**, exactly as `bindings/vitals.rs:229` and `:293` already do.
+
+### 3.1 Feature gating in `wifi-densepose-py`
+
+New Cargo features and optional path-deps in `python/Cargo.toml`; each binding
+module is `#[cfg(feature = "…")]`-compiled and conditionally `register()`ed in
+`src/lib.rs`, so a default build links none of the three:
+
+```toml
+[features]
+default = []
+aether   = ["dep:wifi-densepose-sensing-server"]
+meridian = ["dep:wifi-densepose-train", "dep:wifi-densepose-signal"]
+mat      = ["dep:wifi-densepose-mat"]              # upstream `mat` feature flows through
+sota     = ["aether", "meridian", "mat"]
+
+[dependencies]
+wifi-densepose-sensing-server = { version = "0.3.0", path = "../v2/crates/wifi-densepose-sensing-server", optional = true, default-features = false }
+wifi-densepose-train          = { version = "0.3.0", path = "../v2/crates/wifi-densepose-train", optional = true, default-features = false }  # NO tch-backend
+wifi-densepose-signal         = { version = "0.3.0", path = "../v2/crates/wifi-densepose-signal", optional = true }
+wifi-densepose-mat            = { version = "0.3.0", path = "../v2/crates/wifi-densepose-mat", optional = true, default-features = false }
+```
+
+`[project.optional-dependencies]` in `pyproject.toml` gains `aether`, `meridian`,
+`mat`, and `sota` keys mirroring the existing `client`/`dev` extras. Because each
+extra changes the compiled surface, extras map to **cibuildwheel feature-flag
+builds**, not pure-Python markers — the publish workflow (ADR-117 §5.4) gains a
+build axis for the `[sota]` wheel variant.
+
+### 3.2 Binding surface — AETHER (`wifi_densepose.aether`)
+
+Backing crate: `wifi-densepose-sensing-server::embedding` (ADR-024 §2.6). The
+crate is Axum/tokio-based, so we depend on it `default-features = false` and bind
+**only the sync `embedding` types** — never the server/runtime. If the embedding
+module cannot be reached without a tokio dependency (Open Question §11.1), the
+fallback is to hoist `embedding.rs` into a leaf crate; that is a Rust-side
+refactor, not a Python API change.
+
+| Python symbol | Wraps | Signature (Python) |
+|---|---|---|
+| `AetherConfig` | `AetherConfig` | `AetherConfig(d_model=64, d_proj=128, temperature=0.07, vicreg_alpha=1.0, vicreg_beta=25.0, vicreg_gamma=1.0)` — frozen, `__repr__` |
+| `CsiAugmenter` | `CsiAugmenter` | `CsiAugmenter(seed)`; `.augment(window: list[list[float]]) -> list[list[float]]` |
+| `EmbeddingExtractor` | `EmbeddingExtractor` | `.embed(csi_features: list[list[float]]) -> list[float]` (128-dim, L2-normed); `.forward_dual(...) -> tuple[PoseEstimate, list[float]]` |
+| `aether_loss(...)` | `aether_loss` | returns `AetherLossComponents(total, info_nce, variance, covariance)` — frozen dataclass-like |
+| `cosine_similarity(a, b)` | thin helper | `float`; convenience for re-ID scoring (not a re-impl — calls the same dot product) |
+| `alignment_metric`, `uniformity_metric` | same | `float` |
+
+GIL strategy: `embed`, `forward_dual`, `augment`, and `aether_loss` wrap their
+Rust call in `py.allow_threads(|| …)` — these are pure-sync matrix ops that touch
+no Python objects, matching the vitals precedent. A single-frame `embed()` is
+sub-millisecond (ADR-024 §2.8 target <1 ms FP32), but batch/augment calls exceed
+the 0.5 ms GIL-release threshold ADR-117 §P3 set.
+
+`.pyi` stubs: add `wifi_densepose/aether.pyi` declaring the five classes/functions
+with precise numeric types; extend the top-level `wifi_densepose/__init__.pyi`
+with a `TYPE_CHECKING`-guarded re-export so `mypy --strict` sees them only when
+the extra is installed.
+
+### 3.3 Binding surface — MERIDIAN (`wifi_densepose.meridian`)
+
+Backing crates: `wifi-densepose-train` (inference/adaptation path, **no
+`tch-backend`**) + `wifi-densepose-signal::hardware_norm`. The `model`/`trainer`/
+`losses` modules are libtorch-gated and are **out of scope** — Python gets the
+domain-generalization *inference and calibration* surface, not the training loop.
+
+| Python symbol | Wraps | Signature (Python) |
+|---|---|---|
+| `HardwareType` | `HardwareType` | `#[pyclass(eq, eq_int, hash, frozen)]` enum: `Esp32S3 / Intel5300 / Atheros / Generic`; `HardwareType.detect(subcarrier_count) -> HardwareType` |
+| `HardwareNormalizer` | `HardwareNormalizer` | `.normalize(frame: CsiFrame, hw: HardwareType) -> CanonicalCsiFrame` |
+| `CanonicalCsiFrame` | `CanonicalCsiFrame` | frozen; `.amplitudes`, `.phases`, `.hardware_type` getters |
+| `GeometryEncoder` | `GeometryEncoder` | `GeometryEncoder(MeridianGeometryConfig)`; `.encode(ap_positions: list[tuple[float,float,float]]) -> list[float]` (64-dim, permutation-invariant) |
+| `MeridianGeometryConfig` | `MeridianGeometryConfig` | frozen config |
+| `RapidAdaptation` | `RapidAdaptation` | `.calibrate(csi_windows: list[list[list[float]]]) -> AdaptationResult` (10-sec unlabeled few-shot) |
+| `AdaptationResult` | `AdaptationResult` | frozen result: `.frames_used`, `.converged`, `.loss` |
+| `CrossDomainEvaluator` | `CrossDomainEvaluator` | `.evaluate(...) -> dict[str, float]` (in/cross/few-shot MPJPE, domain-gap ratio) |
+
+GIL strategy: `normalize`, `encode`, `calibrate`, and `evaluate` are wrapped in
+`py.allow_threads`. `normalize` targets <50 µs/frame (ADR-027 §4.1) and `encode`
+<100 µs (§4.3), but `calibrate` runs contrastive test-time training over 200
+frames and is the primary GIL-release beneficiary.
+
+`.pyi` stubs: `wifi_densepose/meridian.pyi`. `DomainFactorizer` /
+`GradientReversalLayer` / `VirtualDomainAugmentor` are **training-time only** and
+are *not* bound in P6 (they need the tch training loop) — Open Question §11.2
+records this boundary.
+
+### 3.4 Binding surface — MAT (`wifi_densepose.mat`)
+
+Backing crate: `wifi-densepose-mat`, bound behind the `[mat]` extra so the
+disaster/ML stack never enters the default wheel — mirroring the upstream `mat`
+cargo feature exactly. `DisasterResponse::start_scanning` is async (tokio); rather
+than bind an event loop, P6 binds the **sync ingest + query surface** and a
+single-shot `scan_once()` helper (a sync wrapper over one `scan_cycle`, added
+Rust-side if needed — see §11.3).
+
+| Python symbol | Wraps | Signature (Python) |
+|---|---|---|
+| `DisasterType` | `DisasterType` | `#[pyclass(eq, eq_int, hash, frozen)]` enum: `Earthquake / BuildingCollapse / Avalanche / Flood / Mine / Unknown` |
+| `TriageStatus` | `TriageStatus` | frozen enum (START protocol classes) |
+| `DisasterConfig` | `DisasterConfig` | builder-style kwargs: `DisasterConfig(disaster_type, sensitivity=0.8, confidence_threshold=0.5, max_depth=5.0)` |
+| `DisasterResponse` | `DisasterResponse` | `.push_csi_data(amplitudes, phases)`; `.scan_once()`; `.survivors() -> list[Survivor]`; `.survivors_by_triage(status) -> list[Survivor]` |
+| `Survivor` | `Survivor` | frozen: `.id`, `.triage_status`, `.location`, `.vital_signs` getters |
+| `VitalSignsReading` | `VitalSignsReading` | frozen: breathing / heartbeat / movement fields |
+
+GIL strategy: `push_csi_data` and `scan_once` wrap the detection-pipeline call in
+`py.allow_threads` — the ensemble classifier + localization are the compute-heavy
+part and touch no Python state.
+
+`.pyi` stubs: `wifi_densepose/mat.pyi`.
+
+---
+
+## 4. Benchmarking & the measured-vs-claimed parity requirement
+
+A binding that "runs without crashing" is worthless if it silently regresses
+accuracy versus the native Rust call. The point of P6 is to prove the Python
+surface reproduces the Rust subsystem **bit-for-bit**, then to hold each binding
+to the *same* published SOTA bar its ADR already claims.
+
+### 4.1 Parity harness (bit-for-bit, mandatory)
+
+Each subsystem ships a golden-vector parity test. A committed input fixture is
+run through **both** a tiny native-Rust reference binary (in
+`v2/crates/wifi-densepose-py/tests/golden/`) and the Python binding; the two
+outputs must hash-match under SHA-256 (the ADR-028 / ADR-117 §5.7 witness scheme):
+
+- `aether`: identical 128-dim embedding bytes for a fixed CSI window + fixed seed.
+- `meridian`: identical `CanonicalCsiFrame` bytes for a fixed ESP32 (64-sub) and
+  Intel-5300 (30-sub) frame; identical 64-dim geometry vector for fixed AP set.
+- `mat`: identical triage classification + survivor count for a fixed CSI stream.
+
+A mismatch is a **release blocker**, not a warning. This is the "MEASURED, not
+CLAIMED" gate the project holds itself to.
+
+**Scope, stated honestly:** parity proves the **strongest claim available today** —
+the Python binding is bit-identical to native Rust for the bound surface. It is
+**not** accuracy validation. The bound AETHER surface moreover ships *untrained*
+(random-init weights; a `load_weights` API exists since `65da488ad` but no trained
+checkpoint exists to load — §6.7.2, §13.c.a), so byte-equality here says nothing
+about the SOTA accuracy bars in §4.3; those remain OPEN (§6.7, §13.c).
+
+### 4.2 pytest-benchmark micro-benchmarks
+
+Following the existing `python/bench/test_bench_vitals.py` pattern (skipped by
+default via `addopts`; run with `pytest python/bench/ --benchmark-only`):
+
+- `python/bench/test_bench_aether.py` — steady-state `embed()` per-window cost;
+  assert < 2 ms (ADR-024 §2.8 FP32 target < 1 ms with headroom) and that batched
+  `embed()` scales linearly (no accidental O(n²)).
+- `python/bench/test_bench_meridian.py` — `normalize()` < 200 µs/frame,
+  `encode()` < 200 µs (ADR-027 §4.1/§4.3 targets ×2 headroom).
+- `python/bench/test_bench_mat.py` — `scan_once()` per-cycle cost bounded by the
+  configured scan interval.
+
+### 4.3 SOTA accuracy bar the binding must reproduce (not merely run)
+
+The parity harness (§4.1) guarantees the Python path is byte-identical to Rust, so
+these published numbers are the bar the *binding output* is validated against on a
+committed labeled fixture — a regression in any is a binding bug:
+
+| Metric | Bar | Source |
+|---|---|---|
+| WiFlow-STD pose accuracy | **~96% PCK@20** (MEASURED-EQUIVALENT) | ADR-152 §2.2 |
+| Room identification (k-NN on `env_fingerprint`) | **> 95%** | ADR-024 §2.8 |
+| Person re-ID mAP | **> 80%** (WhoFi bar 95.5% on NTU-Fi) | ADR-024 §2.8, §1.5 |
+| Anomaly detection F1 | **> 0.90** | ADR-024 §2.8 |
+| INT8 rank correlation vs FP32 (Spearman) | **> 0.95** | ADR-024 §2.8 |
+| Cross-domain MPJPE improvement | **> 20%** vs non-adversarial | ADR-027 §4.2 |
+| Domain-gap ratio (cross/in-domain) | **< 1.5** | ADR-027 §4.6 |
+| Few-shot MPJPE after 10-sec calibration | within **15%** of in-domain | ADR-027 §4.5 |

+
+### P1 — AETHER bindings (`[aether]` extra) — **DONE** (`d060998e3`; leaf-crate hoist `a47bb71b2`)
+
+- [x] `aether` Cargo feature + gated optional `wifi-densepose-sensing-server` dep;
+  default build links **0** sensing-server refs (base wheel stays lean).
+- [x] `python/src/bindings/aether.rs` — `AetherConfig` (→ real `EmbeddingConfig`),
+  `CsiAugmenter.augment_pair`, `EmbeddingExtractor.embed` (128-dim L2-normed,
+  GIL-released), `info_nce_loss`, `cosine_similarity`. **Not bound** (absent in
+  `embedding.rs` at HEAD, a Rust-side gap, not fabricated): `aether_loss`/VICReg
+  components, `alignment_metric`, `uniformity_metric`, `forward_dual`, `vicreg_*`.
+- [x] `#[cfg(feature = "aether")]` gate + facade + `aether.pyi` + `[aether]` extra.
+- [x] `python/tests/golden/aether_embedding.sha256` parity fixture:
+  `tests/aether_parity.rs` locks the native reference; `tests/test_aether.py`
+  asserts identical SHA-256 of the LE-f32 bytes.
+- [x] **Verified:** `cargo test --features aether --test aether_parity` → 2/2;
+  `pytest tests/test_aether.py` → 9/9.
+- [x] **Leaf-crate hoist (`a47bb71b2`):** `embedding.rs` moved into a new
+  `wifi-densepose-aether` crate. Measured stripped wheel **~361 KB → ~312 KB** (was
+  already ~14× under the 5 MB budget — see §13.a; the hoist's value is build-time
+  71 s → 12 s + dep-graph hygiene, not size). No regression: `aether_parity` 2/2,
+  `pytest` 9/9, sensing-server 217+388 tests 0 failed, new `wifi-densepose-aether`
+  crate 96 passed.
+
+### P2 — MERIDIAN bindings (`[meridian]` extra) — **DONE** (`189ac9dfb`)
+
+- [x] `meridian` feature + gated optional `wifi-densepose-train` (**no `tch-backend`
+  — libtorch avoided, confirmed**) + `wifi-densepose-signal` deps.
+- [x] `python/src/bindings/meridian.rs` — `HardwareType`/`HardwareNormalizer`/
+  `CanonicalCsiFrame` (real API: `normalize(amplitude, phase, hw)` over f64 →
+  `Result`; singular `amplitude`/`phase` fields), `MeridianGeometryConfig`/
+  `GeometryEncoder` (64-dim, permutation-invariant), `RapidAdaptation`
+  (**real API: `push_frame` + `adapt()`**, not the ADR's `calibrate`) →
+  `AdaptationResult` (`lora_weights`/`final_loss`/`frames_used`/
+  `adaptation_epochs`; **no `converged`**), `CrossDomainEvaluator` + `mpjpe`. All
+  compute paths GIL-released. Training-time types (`DomainFactorizer`, GRL,
+  `VirtualDomainAugmentor`) correctly left out of P6 scope.
+- [x] Gate + facade + `meridian.pyi` + `[meridian]` extra; default dep graph has 0
+  train/signal/sensing-server refs.
+- [x] `tests/golden/meridian_output.sha256` parity fixture (esp32 + intel canonical
+  frames + 64-dim geometry vector + rapid-adapt LoRA weights).
+- [x] **Verified:** `cargo test --features meridian --test meridian_parity` → 2/2;
+  `pytest tests/test_meridian.py` → 13/13.
+
+### P3 — MAT bindings behind `[mat]` extra — **DONE** (`1c9727f9c`)
+
+- [x] `mat` feature + gated optional `wifi-densepose-mat` dep. **§11.3 resolved: no
+  Rust change needed** — the public async `start_scanning()` already runs exactly
+  one `scan_cycle` when `continuous_monitoring == false`; the binding forces that
+  flag off and drives one cycle on a private current-thread tokio runtime.
+- [x] `python/src/bindings/mat.rs` — `DisasterType` (**9 variants at HEAD**, not the
+  6 the ADR listed), `TriageStatus` (5, START), `DisasterConfig`,
+  `DisasterResponse` (`initialize_event`/`add_zone`/`push_csi_data`/`scan_once`/
+  `survivors`/`survivors_by_triage` — `initialize_event`+`add_zone` are **required
+  additions** the ADR surface omitted), `Survivor` (`latest_vitals`, since real
+  `vital_signs` is a history), `VitalSignsReading`, `ScanZone.rectangle`/`.circle`.
+  `push_csi_data`+`scan_once` GIL-released.
+- [x] Gate + facade + `mat.pyi` + `[mat]` **and** `[sota]` (superset) extras.
+- [x] `tests/golden/mat_result.sha256` parity fixture over a canonical
+  `count=<K>;triage_priorities=<sorted>` string (UUIDs/timestamps excluded as
+  non-deterministic). **Honest scope: proves binding==native path, NOT live
+  detection accuracy** — the synthetic stream yields 1 survivor, triage Delayed.
+- [x] **Verified:** `cargo test --features mat --test mat_parity` → 2/2;
+  `pytest tests/test_mat.py` → 7/7.
+
+### P4 — Docs, examples, and benchmark suite — **DONE** (`0f405213d`)
+
+- [x] `python/bench/test_bench_{aether,meridian,mat}.py` (pytest-benchmark, §4.2).
+  Measured on a `--release --features sota` wheel: AETHER `embed()` ~150 µs
+  (target <2 ms), batch 1/8/64 = 140/1091/8509 µs (linear); MERIDIAN `normalize()`
+  ~2.2 µs (target <200 µs), `encode()` ~6.9 µs; MAT ingest+`scan_once()` ~40 ms /
+  256-frame (< 500 ms). All pass.
+- [x] `python/examples/{reid_from_csi,cross_room_calibrate,mat_triage}.py` — typed,
+  runnable, `mypy --strict` clean; README SOTA extras table.
+- [~] Parity harness wiring into CI as a **release-blocking gate** — golden gates
+  are green locally (`cargo test --features sota` → 6/6; 3/3 SHA gates), but the CI
+  **wiring** is not done (§6.6 PARTIAL — see §13.b).
+- [ ] Update ADR-117 §6 "P6+ Deferred" to point at this ADR — still open.
+
+### P5 — New required follow-ups (blocking Accepted)
+
+See §13. In short: (a) three leaf-crate hoists — **DONE** (`a47bb71b2`/`7ed57f041`/
+`99fea9df9`; only MAT was a real budget fix, AETHER was a false alarm), (b) wire the
+parity harness into CI as an actual release gate — **still open**, (c) source/generate
+labeled fixtures to validate the SOTA accuracy bars (§4.3) for real — **still open**.
+
+### P6+ — Deferred (unchanged from ADR-117)
+
+- [ ] `wifi-densepose-nn` / libtorch bindings (MERIDIAN training loop,
+  `DomainFactorizer`, GRL) — still blocked on the libtorch wheel-size question.
+- [ ] `wifi-densepose-ruvector` RuVector attention bindings.
+- [ ] Matter integration helpers.

+
+## 6. Acceptance criteria
+
+Status recorded from the P4 self-verification run (`0f405213d`), reference machine
+per ADR-117 §10. **7 of 9 met; 2 remain** — the ADR is therefore **not** Accepted.
+
+- [x] **§6.1** `pip install wifi-densepose` (no extras) → default wheel **279 KB**
+  (≤ 5 MB); `build_features()` carries no `p6-*` feature — base wheel byte-for-byte
+  unaffected by P6. **PASS**
+- [x] **§6.2** `pytest python/tests/test_aether.py -q` — **9/9**, incl. a real
+  128-dim `embed()` round-trip asserting L2-norm ≈ 1.0 and byte-identity to the
+  golden Rust reference. **PASS**
+- [x] **§6.3** `pytest python/tests/test_meridian.py -q` — **13/13**, incl.
+  ESP32 (64-sub) **and** Intel-5300 (30-sub) canonicalization hash-matching native
+  Rust. **PASS**
+- [x] **§6.4** `pytest python/tests/test_mat.py -q` — **7/7**, incl. a fixed CSI
+  stream whose triage classification matches native `DisasterResponse` exactly.
+  **PASS**
+- [x] **§6.5** `pytest python/bench/ --benchmark-only` — all targets met (AETHER
+  `embed()` ~150 µs < 2 ms; MERIDIAN `normalize()` ~2.2 µs, `encode()` ~6.9 µs
+  < 200 µs; MAT `scan_once()` ~40 ms < 500 ms). **PASS**
+- [~] **§6.6** Parity harness (§4.1): all three golden-vector SHA-256 gates green
+  (`cargo test --features sota` → 6/6). **But CI wiring** as a release-blocking
+  gate is **not done** (out of `python/` scope). **PARTIAL — see §13.b.**
+- [ ] **§6.7** SOTA-bar reproduction (§4.3): **definitively OPEN** — cannot be
+  closed transitively via the parity harness. Investigated; three concrete reasons:
+  1. **The native SOTA numbers aren't reproduced by any committed, runnable-today
+     test.** ADR-152 ~96% PCK@20 is a frozen result in
+     `benchmarks/wiflow-std/results/eval_retrained.json` that points at an **external
+     checkpoint** (`/home/ruvultra/wiflow-std-bench/upstream/test/best_pose_model.pth`,
+     not in the repo); the only relevant test `test_wiflow_std_parity.rs` is
+     `#![cfg(feature = "tch-backend")]` **and** `#[ignore]`d (needs gitignored
+     fixtures + LibTorch). ADR-027's `eval.rs::CrossDomainEvaluator` tests are pure
+     unit-math on hand-coded 2–3-element vectors, not dataset accuracy. ADR-024's
+     only accuracy-ish test asserts Spearman > 0.90 on **synthetic random**
+     embeddings (not real CSI, not the published > 0.95 bar); no room-ID / mAP /
+     anomaly-F1 test exists at all.
+  2. **The bound AETHER surface ships untrained.** `EmbeddingExtractor`/
+     `ProjectionHead` default to random Xavier init (`Linear::with_seed(…,
+     2024/2025)`, `embedding.rs:97–98`). A weight-loading API now **does** exist
+     (`load_weights`/`save_weights`, `65da488ad` — see §13.c.a), so the earlier
+     "no loading path" blocker is removed; but **no trained checkpoint exists** to
+     load, so the binding still produces untrained embeddings and cannot validate
+     mAP > 80% or any trained-model bar today.
+  3. **No committed labeled CSI input/pose-pair data exists** to reuse (MM-Fi/NTU-Fi
+     appear only as config-default subcarrier counts / external paths;
+     `benchmarks/wiflow-std/results/*.npy` are corruption masks + result summaries,
+     not labeled fixtures).
+  The §4.1 parity harness proves the **strongest claim available today** — the
+  Python binding is bit-identical to native Rust for the bound (untrained) surface.
+  That is **not** accuracy validation. **See §13.c.**
+- [x] **§6.8** `.pyi` stubs present for all three modules; `mypy --strict` passes on
+  the three examples. **PASS**
+- [x] **§6.9** `python -c "import wifi_densepose.aether"` (etc.) on the base wheel
+  raises a clear `ImportError` naming the missing extra. **PASS**
+
+No regression: 76 pre-existing tests pass on the default wheel. The two unmet
+criteria (§6.6 CI wiring, §6.7 accuracy) plus the wheel-size hoists (§13.a) are the
+gate to Accepted.
+
+---
+
+## 7. Consequences
+
+### 7.1 Positive
+
+- **Closes the ADR-117 P6 gap**: the three most-requested SOTA subsystems become
+  scriptable from Python without touching the Rust workspace.
+- **Default wheel stays lean**: feature-gated extras preserve ADR-117 §5.4's ≤ 5 MB
+  budget and "no heavy system deps" invariant; MAT's ML stack and MERIDIAN's
+  libtorch path never enter the base wheel.
+- **Reuses the proven idiom**: no new binding machinery — same `#[pyclass]` +
+  `py.allow_threads` + `register()` pattern already shipping in `bindings/vitals.rs`.
+- **Prove-everything alignment**: the parity harness makes "the Python binding
+  equals the Rust core" a *measured, hash-verified* claim, not an assertion —
+  matching the project's MEASURED-vs-CLAIMED discipline.
+- **Upstream consistency**: `[mat]` pip extra mirrors the `mat` cargo feature, so
+  the Python packaging story matches the Rust one exactly.
+
+### 7.2 Negative
+
+- **cibuildwheel matrix grows**: `[sota]` is a distinct compiled variant, adding a
+  build axis (and CI time) beyond ADR-117's 5-wheel abi3 matrix.
+- **AETHER's backing crate is server-shaped**: depending on
+  `wifi-densepose-sensing-server` (Axum/tokio) risks pulling a runtime into an
+  extension module; may force a Rust-side refactor to hoist `embedding.rs` into a
+  leaf crate (§11.1).
+- **MERIDIAN surface is partial**: training-time types (`DomainFactorizer`, GRL,
+  `VirtualDomainAugmentor`) stay unbound until the deferred libtorch tier, so the
+  Python API is inference/adaptation-only — potential user confusion (mitigated by
+  docs + `.pyi` omissions).
+- **Golden fixtures are maintenance surface**: any intentional numeric change in a
+  Rust subsystem requires regenerating and re-witnessing its golden vector.
+
+### 7.3 Neutral
+
+- The `[sota]` convenience extra is purely additive; users who want one subsystem
+  install one extra.
+- No change to the v2.0.0 semver line; extras ship additively as v2.x.y.
+
+---
+
+## 8. Alternatives considered
+
+### Alt-A: Fold all three into the default wheel
+
+Rejected — breaks ADR-117 §5.4's ≤ 5 MB budget, drags MAT's ML stack and (via
+MERIDIAN training) libtorch into every install, and contradicts the upstream
+`mat` cargo-feature gating.
+
+### Alt-B: Separate PyPI packages (`wifi-densepose-aether`, etc.)
+
+Rejected for the SOTA trio — three packages fragment the import namespace and
+duplicate the abi3/cibuildwheel setup. (This remains the right call for the
+libtorch `nn` tier per ADR-117 Open Q §11.2, which is genuinely heavy.) Extras of
+one wheel keep `wifi_densepose.*` coherent.
+
+### Alt-C: Pure-Python reimplementation of the three subsystems
+
+Rejected explicitly — this is the exact drift ADR-117 §8 Alt-C was created to
+exit. A Python reimplementation would immediately begin diverging from the Rust
+SOTA and could not pass the §4.1 bit-for-bit parity gate.
+
+### Alt-D: REST/WS client to a running sensing-server for AETHER
+
+Rejected as the primary path — provides zero offline embedding utility and cannot
+host the parity harness over local Rust code (same reasoning as ADR-117 §8 Alt-B).
+The pure-Python client layer (`[client]`) remains available for streaming.
+
+---
+
+## 9. Risks
+
+| Risk | Likelihood | Severity | Mitigation |
+|---|---|---|---|
+| `wifi-densepose-sensing-server` pulls tokio into the extension module | ~~High~~ **Not realized** | ~~High~~ **Low** | **Measured, not realized:** the stripped `[aether]` wheel was **~361 KB** (14× under budget) even before the hoist — linker DCE (`--gc-sections`) strips the server's unreached Axum/tokio/worldgraph code because the binding reaches only pure-compute symbols. Hoist (`a47bb71b2`) still done for build-time / dep-graph hygiene, not budget. See §11.1, §13.a |
+| MERIDIAN accidentally links `tch-backend` (libtorch) via a default feature | Medium | High | Explicit `default-features = false` on `wifi-densepose-train`; CI `auditwheel`/`ldd` check that no libtorch symbol is present in the `[meridian]` wheel |
+| `[sota]` build axis blows up cibuildwheel time | Medium | Medium | Build `[sota]` variant only on tagged releases, not every PR |
+| Golden vectors drift when a Rust subsystem changes intentionally | Medium | Low | Documented regeneration step + ADR-028 witness re-sign; parity mismatch is a loud release blocker, never silent |
+| MAT async-only surface has no clean sync entry point | Medium | Medium | Add sync `scan_once()` wrapper Rust-side (§11.3) before binding |
+| Users install base wheel and expect `wifi_densepose.aether` | Low | Low | Clear `ImportError` naming the missing extra (acceptance criterion §6) |
+
+---
+
+## 10. Compatibility
+
+- No change to the default wheel, its abi3-py310 base, or its size budget.
+- Extras ship additively on the existing v2.x line; no semver break.
+- `[mat]` pip extra ↔ `mat` cargo feature parity is preserved by construction.
+- `.pyi` stubs are gated so `mypy --strict` only sees a subsystem when its extra
+  is installed.
+
+---
+
+## 11. Open questions
+
+1. **AETHER crate shape** — **RESOLVED (`a47bb71b2`).** The original worry that
+   linking `wifi-densepose-sensing-server` would bloat the wheel was **never
+   measured** — it reasoned from the dependency tree (server has non-optional
+   tokio/Axum ⇒ wheel must be huge). The stripped-release measurement disproves it:
+   `[aether]` was **369,782 B (~361 KB)** *before* the hoist — already ~14× under
+   the 5 MB budget — and **319,719 B (~312 KB)** after. Linker dead-code elimination
+   (`--gc-sections` on the pyo3 cdylib) already strips the server's unreached
+   Axum/tokio/worldgraph/ruvector paths because the binding reaches only
+   pure-compute symbols. The hoist into `wifi-densepose-aether` was still done — its
+   real payoff is **build-time** (`[aether]` alone 71 s → 12 s), **dep-graph
+   hygiene** (`python/Cargo.lock` −1238 lines), and **removing latent risk** (a
+   future change that makes server code reachable would then genuinely bloat the
+   wheel). **Convention note:** measure the stripped release wheel size before
+   assuming a dependency-tree risk requires a hoist — linker DCE handles pure-Rust
+   unreached code, but native/FFI-bundled deps (e.g. `ort`/ONNX Runtime, see §13.a
+   MAT) are *not* stripped and are the real size-risk category.
+
+2. **MERIDIAN training-time types**: `DomainFactorizer`, `GradientReversalLayer`,
+   and `VirtualDomainAugmentor` are meaningful only with the tch training loop.
+   Confirm they stay unbound in P6 and move with the deferred libtorch tier.
+   *Tentative: yes — P6 is inference/adaptation only.*
+
+3. **MAT sync entry point**: `DisasterResponse::start_scanning` is an async tokio
+   loop. Does a sync single-cycle `scan_once()` already exist, or must it be added
+   Rust-side? *Tentative: add a thin sync `scan_once()` wrapping one `scan_cycle`;
+   do not bind an event loop into the extension.*
+
+4. **`[sota]` wheel vs per-extra wheels**: cibuildwheel builds one binary per
+   feature-set. Do we publish one `[sota]` wheel and let pip select, or per-extra
+   wheels? This affects the number of build variants. *Tentative: single `[sota]`
+   superset wheel on tagged releases; base wheel stays feature-free.*

+5. **INT8 embedding path in Python**: ADR-024 §2.8 sets an INT8 rank-correlation

+
+## 13. Open follow-ups (blocking Accepted)
+
+P1–P4 are real, well-tested progress: **32/32 binding tests** (aether 9, meridian
+13, mat 7, + 3 smoke) and **6/6 native parity tests** all pass, verified on the
+reference machine. The three leaf-crate hoists (§13.a) are now **done**. Two items
+still gate Accepted: **§13.b** (wire the parity harness into CI as a release gate)
+and **§13.c** (the SOTA accuracy gap — bindings are structurally *untrained*, and no
+eval harness or labeled data exists yet; genuine long-term work, not a quick fix).
+
+### 13.a — Leaf-crate hoists (all three DONE) — one real fix, one minor, one false alarm
+
+All three extras' backing crates carry heavy declared deps, so the hoist was applied
+to each. But **measuring the stripped release wheel** (not reasoning from the
+dependency tree) showed the wheel-size story differs sharply per extra. Linker
+dead-code elimination (`--gc-sections` on the pyo3 cdylib) strips **pure-Rust
+unreached** code, so a heavy declared dep tree does **not** imply a big wheel;
+**native/FFI-bundled** deps (`ort`/ONNX Runtime's native library) are the exception
+— DCE cannot strip them, and those are the real size risk.
+
+| Extra | Commit | Wheel size (stripped) | Verdict |
+|---|---|---|---|
+| `[aether]` | `a47bb71b2` | **~361 KB → ~312 KB** | **False alarm.** Never breached the 5 MB budget — DCE already stripped the sensing-server's unreached Axum/tokio/worldgraph/ruvector code. Hoist justified by build-time (71 s → 12 s), dep-graph hygiene (`Cargo.lock` −1238 lines), and latent-risk removal — **not** budget. |
+| `[mat]` | `7ed57f041` | **8.4 MB → 2.0 MB** | **Real, measured regression.** `wifi-densepose-nn` bundles `ort`/ONNX Runtime, a **native** library DCE does **not** strip → genuine breach. Fix necessary and correctly characterized. |
+| `[meridian]` | `99fea9df9` | **1.8 MB → 1.7 MB** | **Real but minor.** Measured from the start; a dead dep removed. Already under budget; small win. `libtorch` correctly avoided throughout (`tch` optional, off). |
+
+These were changes **inside** the upstream `v2/` crates (owned by other agents this
+session); the default wheel was unaffected throughout because every extra is
+feature-gated off. All three hoists are now landed — the remaining Accepted blockers
+are §13.b (CI gate) and §13.c (accuracy fixtures), **not** wheel size.
+
+### 13.b — Wire the parity harness into CI as a real release gate (§6.6)
+
+The three golden-vector SHA-256 gates pass locally (`cargo test --features sota` →
+6/6) but are not yet wired into a CI workflow that **blocks release** on mismatch.
+Add a job to the ADR-117 §5.4 publish pipeline that runs the native `*_parity.rs`
+references + the `pytest` binding checks and fails the release on any divergence.
+
+### 13.c — Close the SOTA accuracy gap (§4.3, §6.7) — genuine long-term work
+
+This is the most important honesty gap and it is **more fundamental than missing
+labeled data** (see §6.7 for the three findings). The parity harness proves the
+Python binding is **byte-identical to the native Rust path** for the bound, **but
+untrained**, surface — it does **not** prove the cited SOTA numbers (ADR-152
+~96% PCK@20; ADR-024 room-ID > 95% / re-ID mAP > 80% / anomaly F1 > 0.90; ADR-027
+cross-domain MPJPE + 20% / domain-gap < 1.5). Those bars remain **CLAIMED, not
+MEASURED** by this work.
+
+Closing it requires three steps, in dependency order:
+
+- **(a) Add trained-weight loading to the AETHER/pose bindings — DONE (`65da488ad`).**
+  `EmbeddingExtractor` gained `save_weights(path)` / `load_weights(path)` /
+  `param_count` on both the native crate and the Python binding (GIL-released,
+  `ValueError`/never-panics on bad input), removing the "structurally untrained, no
+  loading path" blocker: a real checkpoint can now be loaded whenever one exists.
+  Default construction is unchanged (still random `with_seed` init, clearly labeled
+  untrained) — purely additive. **Format tradeoff:** rather than pull in
+  `safetensors`/`serde`/`bincode`, the on-disk format is raw little-endian `f32`
+  with a 12-byte header (8-byte magic `AETHERW1` + `u32` param count), reusing the
+  pre-existing `flatten_weights`/`unflatten_weights` — this deliberately preserves
+  `wifi-densepose-aether`'s zero-dependency std-only leaf-crate property from the
+  §13.a hoist. **Verified:** `cargo test -p wifi-densepose-aether` 98/98; parity 3/3
+  incl. the new cross-language golden `aether_weights_parity.rs` (native Rust and the
+  Python binding load the same weight file and produce a byte-identical embedding
+  SHA-256, and the loaded weights demonstrably move the output off the random-init
+  baseline — not a silent no-op); `pytest test_aether.py` 13/13 (up from 9).
+  **This does NOT close §6.7** — it is the *capability* to load weights, not trained
+  weights; (b) and (c) below remain, and no SOTA number is validated yet.
+- **(b) Commit or source a small labeled CSI fixture** (input CSI + ground-truth
+  pose/identity/room labels) — **still OPEN.** Genuine **data-acquisition scope**.
+- **(c) Build a real eval harness** computing PCK / mAP / room-ID / anomaly-F1 /
+  Spearman on (a)+(b) and asserting the published bars — **still OPEN.**
+
+With (a) landed, the remaining work is (b) and (c): genuine research /
+data-acquisition scope beyond one session. This is now purely a data-availability +
+missing-eval-infra problem, **not** a binding defect. Status stays **Proposed**
+until (b)–(c) land and §4.3 is run for real.

+# ADR-186: Training progress API — wire the orphaned in-server trainer to `/ws/train/progress`

+| **Tracking issue** | [#1233](https://github.com/ruvnet/wifi-densepose/issues/1233) — "Training does not start – /ws/train/progress returns 404 and no model is generated" (open) |
+
+---
+
+## 1. Context
+
+### 1.1 The reported gap
+
+A user starting training from the web dashboard hits
+`ws://localhost:3000/ws/train/progress`, which **404s**, and the backend never
+produces a trained `.rvf` model or any further log output beyond a single
+"Training started" line. Issue #1233 is open, and the repo owner's own comment on
+it states:
+
+> The `/ws/train/progress` WebSocket endpoint is not yet exposed in the stable
+> server — the training pipeline (room-calibration specialists, MAE pretraining)
+> runs via the CLI (`wifi-densepose train-room`) rather than through the
+> HTTP/WebSocket API, which is why the Docker image returns 404 for that path.
+
+So the dashboard has a **"Start Training" button that silently no-ops**: it POSTs a
+config, receives a `success: true` response, and then nothing happens — no error is
+surfaced, no model is produced, no progress stream exists. A button that appears to
+work but does nothing is the definition of slop, and this ADR exists to close that
+gap honestly.
+
+### 1.2 What the live server actually does today (evidence)
+
+The stable server mounts **stub** training handlers. The POST handler flips a string
+flag, logs one line, and returns success — it starts no job:
+
+```rust
+// v2/crates/wifi-densepose-sensing-server/src/main.rs:4986–5006
+async fn train_start(
+    State(state): State<SharedState>,
+    Json(body): Json<serde_json::Value>,
+) -> Json<serde_json::Value> {
+    let mut s = state.write().await;
+    if s.training_status == "running" { /* ... */ }
+    s.training_status = "running".to_string();
+    s.training_config = Some(body.clone());
+    info!("Training started with config: {}", body);   // ← the one log line the issue reports
+    Json(serde_json::json!({
+        "success": true,
+        "status": "running",
+        "message": "Training pipeline started. Use GET /api/v1/train/status to monitor.",
+    }))
+}
+```
+
+These three stubs — and **nothing else training-related** — are wired into the live
+router:
+
+```rust
+// v2/crates/wifi-densepose-sensing-server/src/main.rs:8068–8071
+// Training endpoints
+.route("/api/v1/train/status", get(train_status))
+.route("/api/v1/train/start",  post(train_start))
+.route("/api/v1/train/stop",   post(train_stop))
+```
+
+There is **no `/ws/train/progress` route in the live app** — hence the 404 that
+issue #1233 reports. The stub state fields backing them are just:
+
+```rust
+// v2/crates/wifi-densepose-sensing-server/src/main.rs:1125–1127
+training_status: String,               // "idle" | "running" | ...
+training_config: Option<serde_json::Value>,
+```
+
+### 1.3 The surprising finding: a real trainer already exists, orphaned
+
+The gap is **not** that training was never built for the server. A complete
+in-server training pipeline **already exists in the tree** at
+`v2/crates/wifi-densepose-sensing-server/src/training_api.rs` (1,860 lines). Its own
+module doc describes what it does (`training_api.rs:1–25`):
+
+- Loads recorded CSI from `.csi.jsonl` files, extracts signal features (subcarrier
+  variance, temporal gradients, Goertzel frequency-domain power).
+- Trains a regularised linear model via batch gradient descent.
+- Exports a calibrated `.rvf` model container via `RvfBuilder` on completion.
+- **"No PyTorch / `tch` dependency is required. All linear algebra is implemented
+  inline using standard Rust math."** (`training_api.rs:11–13`)
+
+It runs training on a **background tokio task** and streams progress over a
+`tokio::sync::broadcast` channel to a real WebSocket handler:
+
+- `start_training` spawns the job: `tokio::spawn(async move { ... })`
+  (`training_api.rs:1564`, spawn at `:1610`).
+- `ws_train_progress_handler` subscribes to `training_progress_tx` and forwards
+  `{"type":"progress", "data": …}` frames (`training_api.rs:1778–1836`).
+- A `routes()` factory wires the whole surface, **including the missing route**:
+
+```rust
+// v2/crates/wifi-densepose-sensing-server/src/training_api.rs:1841–1849
+pub fn routes() -> Router<AppState> {
+    Router::new()
+        .route("/api/v1/train/start",    post(start_training))
+        .route("/api/v1/train/stop",     post(stop_training))
+        .route("/api/v1/train/status",   get(training_status))
+        .route("/api/v1/train/pretrain", post(start_pretrain))
+        .route("/api/v1/train/lora",     post(start_lora_training))
+        .route("/ws/train/progress",     get(ws_train_progress_handler))
+}
+```
+
+**This module is dead code.** There is no `mod training_api;` declaration anywhere
+in the crate — a repo-wide search for `training_api` returns only a doc-comment
+mention in `path_safety.rs:9`. Because Rust never sees the file without a `mod`
+declaration, `training_api.rs` is **not compiled into the binary at all**, and
+`training_api::routes()` is never merged into the app. It was written, committed
+(last touched by commit `9b07dff29`), and then orphaned.
+
+### 1.4 Why it would not even compile if naively wired in
+
+The orphan was written against a **different state shape than the one that shipped**.
+`training_api.rs` expects its parent to expose an `AppStateInner` carrying a training
+sub-state and a broadcast sender:
+
+```rust
+// v2/crates/wifi-densepose-sensing-server/src/training_api.rs:249
+pub type AppState = Arc<RwLock<super::AppStateInner>>;
+// handlers read s.training_state.status, s.training_state.task_handle,
+// s.training_progress_tx  (e.g. training_api.rs:1588, :1610, :1788)
+```
+
+But the **real** `AppStateInner` (`main.rs:1024`, aliased `SharedState` at
+`main.rs:1249`) has none of those fields — only the `training_status: String` /
+`training_config` stubs from §1.2. `training_state: TrainingState` is defined
+locally in `training_api.rs:232`, and `training_progress_tx` exists nowhere on the
+live state. So adding `mod training_api;` today produces a compile error: the module
+references `AppStateInner` fields that do not exist. Wiring it in requires
+**reconciling the state struct first**, not merely uncommenting a route.
+
+### 1.5 The working path today
+
+The path that actually trains a model is the CLI, exactly as the maintainer's
+comment says:
+
+- `wifi-densepose train-room` → `room.rs:241` `train_room(...)`, the ADR-151
+  Stage-2–5 per-room specialist-bank trainer (`enroll → train-room → room-watch`).
+- The heavier `wifi-densepose-train` crate exposes epoch-level metrics
+  (`trainer.rs:43` `pub epoch: usize`, `trainer.rs:64` `best_epoch`) that a progress
+  stream could surface directly — the data a WebSocket needs already exists in the
+  training loop.
+
+### 1.6 What this ADR is *not*
+
+- Not a rewrite of the trainer. The pipeline in `training_api.rs` already exists;
+  this ADR reconnects and hardens it.
+- Not a move of GPU/`tch`-backed training into the Axum server. The in-server
+  trainer is deliberately `tch`-free (§1.3). Heavy MAE/LoRA training stays in the
+  CLI / `wifi-densepose-train` crate; the server streams progress for the light,
+  pure-Rust specialist trainer and (optionally) proxies status for CLI-launched runs.
+- Not a change to the `train-room` CLI contract (ADR-151). The CLI remains the
+  authoritative path for offline / batch training.
+

+## 2. Current state — evidence
+
+| Artifact | Value | Source |
+|---|---|---|
+| Live POST handler | `train_start` — flips a flag, logs, returns `success:true`, starts no job | `main.rs:4986–5006` |
+| The "Training started" log line from the issue | `info!("Training started with config: {}", body)` | `main.rs:5000` |
+| Live training routes | `train/status`, `train/start`, `train/stop` (stubs only) | `main.rs:8068–8071` |
+| `/ws/train/progress` in live app | **Absent** → 404 | (no route in `main.rs` router) |
+| Live training state fields | `training_status: String`, `training_config: Option<Value>` | `main.rs:1125–1127` |
+| Real in-server trainer | 1,860-line implemented pipeline, `tch`-free, exports `.rvf` | `training_api.rs:1–25` |
+| Real WS progress handler | subscribes to broadcast, streams `progress` frames | `training_api.rs:1778–1836` |
+| Real route factory (has the missing route) | `routes()` incl. `/ws/train/progress` | `training_api.rs:1841–1849` |
+| Background job spawn | `tokio::spawn` of the training task | `training_api.rs:1564`, spawn `:1610` |
+| `mod training_api;` declaration | **None in the crate** (only a doc mention) | `path_safety.rs:9` |
+| State-shape mismatch | expects `super::AppStateInner.{training_state, training_progress_tx}` | `training_api.rs:249`, `:232` |
+| Real `AppStateInner` / `SharedState` | has neither field | `main.rs:1024`, `:1249` |
+| Working training path | CLI `train-room` (ADR-151 specialist bank) | `room.rs:241` |
+| Epoch metrics available to stream | `TrainMetrics.epoch`, `best_epoch` | `train/src/trainer.rs:43`, `:64` |
+

+
+## 3. Gap analysis
+
+| Capability | Desired | Today | Gap severity |
+|---|---|---|---|
+| `/ws/train/progress` resolves | 101 Switching Protocols, streams epoch/loss/eta | 404 (route absent) | **Critical** — the reported bug |
+| "Start Training" produces a model | background job trains and writes `.rvf` | flag flip + one log line, no job, no model | **Critical** |
+| Error surfaced to the user | button reflects real state / disabled with reason | silent no-op, `success:true` | **Critical** (slop) |
+| In-server trainer compiled | part of the crate, unit-tested | orphaned; not compiled (no `mod`) | **High** |
+| State supports progress streaming | `training_state` + `training_progress_tx` on `AppStateInner` | absent — orphan won't compile as-is | **High** |
+| WS auth on the training surface | `/ws/train/progress` under bearer gate (ADR-166 §Sprint-1) | n/a (route absent) | **High** |
+| `dataset_ids` path safety | validated before file open | `path_safety.rs` exists but unreached by live routes | **Medium** |
+| Server ↔ CLI parity | shared/consistent training semantics | two divergent trainers (stub vs CLI vs orphan) | **Medium** |
+
+---
+
+## 4. Decision
+
+**Chosen path: wire the existing in-server trainer into the live server** — reconcile
+the state struct, declare the module, merge `training_api::routes()`, delete the
+stub handlers, and expose a real `/ws/train/progress` that streams epoch/loss/eta
+events from the already-implemented background job.
+
+This is called **TRAIN-RECONNECT**.
+
+### 4.1 Why this path, and not "make the button honestly say CLI-only"
+
+The task framing offered two honest options. Investigation decided it:
+
+| Consideration | Evidence | Implication |
+|---|---|---|
+| Is server-side training genuinely GPU/`tch`-bound (→ keep CLI-only)? | The in-server trainer is explicitly **`tch`-free**, pure Rust, exports `.rvf` (`training_api.rs:11–13`) | The "too heavy for Axum" argument is contradicted by the code |
+| Does a real streaming implementation already exist? | Full pipeline + broadcast + WS handler + `routes()` present (`training_api.rs:1564,1778,1841`) | The impressive-sounding option is also the *least* new code — it already exists |
+| Why does it 404 then? | No `mod training_api;`; state-shape mismatch (`:249` vs `main.rs:1024`) | The fix is reconnection + reconciliation, not new invention |
+
+Because the honest, code-supported reality is "a working trainer was written and left
+unplugged," the right decision is to plug it in — this is not choosing the flashier
+option over the code; it *is* what the code says.
+
+**However**, path B is retained as a **mandatory fallback guarantee** (Phase P5): if,
+for a given build/deployment, server-side training is disabled (e.g. behind a
+feature flag, or on the lightweight appliance image where recordings aren't
+available), the dashboard button MUST be disabled with a tooltip pointing at
+`wifi-densepose train-room` — never a silent `success:true` no-op again. The slop is
+eliminated in both the enabled and disabled configurations.
+
+### 4.2 Scope boundary — light trainer streams, heavy trainer proxies
+
+- The **pure-Rust specialist trainer** (`training_api.rs`, ADR-151 flavour) runs
+  in-process and streams live epoch/loss/eta over `/ws/train/progress`.
+- **Heavy MAE/LoRA training** (`wifi-densepose-train`, `tch`/GPU) stays CLI-launched.
+  The server does not host it; at most `/api/v1/train/status` reports on a
+  CLI-launched run if one registers itself. Streaming heavy training is out of scope
+  for this ADR (noted as an open question, §8).
+
+---
+
+## 5. Detailed design
+
+### 5.1 Reconcile `AppStateInner`
+
+Replace the two stub fields (`main.rs:1125–1127`) with the sub-state the trainer
+expects, so `training_api.rs` compiles against `super::AppStateInner`:
+
+```rust
+// main.rs — inside AppStateInner (replacing training_status / training_config)
+training_state: training_api::TrainingState,          // status, epoch, best_pck, task_handle
+training_progress_tx: tokio::sync::broadcast::Sender<String>,  // progress fan-out
+```
+
+`train_status` consumers that read `s.training_status` / `s.training_config` are
+updated to read `s.training_state.status`. The broadcast sender is created at state
+init (`main.rs:7826` region, where the stubs are seeded today).
+
+### 5.2 Declare and merge the module
+
+- Add `mod training_api;` to `main.rs` (or `pub mod` in `lib.rs` if the router is
+  assembled there).
+- Delete the stub handlers `train_start` / `train_stop` / `train_status`
+  (`main.rs:4977–5023`) and their three route mounts (`main.rs:8069–8071`).
+- Merge the real router **after** `.with_state(state.clone())`, the same pattern the
+  RuField surface already uses (`main.rs:8104–8111`):
+
+```rust
+// main.rs router assembly
+.merge(training_api::routes())
+```
+
+so that `/api/v1/train/*` and `/ws/train/progress` resolve against the shared state.
+
+### 5.3 Auth and safety (ADR-166 alignment)
+
+- `/api/v1/train/*` sits under the existing opt-in bearer gate (`main.rs:8095–8102`,
+  `RUVIEW_API_TOKEN`). `/ws/train/progress` follows the same policy decision made for
+  `/ws/sensing` — document explicitly whether the training WS is gated (recommended:
+  gated when a token is set, since training reads/writes recordings and models).
+- `dataset_ids` from `StartTrainingRequest` (`training_api.rs:126–130`) are resolved
+  through `path_safety` before any file open — `path_safety.rs:9` already anticipates
+  `{dataset_id}.csi.jsonl` under `RECORDINGS_DIR`; wire it in the load path.
+- Single-job concurrency guard: `start_training` already rejects a second run while
+  `training_state.status.active` (`training_api.rs:1571`) — keep it.
+
+### 5.4 Progress event schema (already emitted)
+
+The WS handler already frames messages as `{"type":"status"|"progress", "data": …}`
+(`training_api.rs:1796–1815`). Confirm the `data` payload carries at minimum
+`epoch`, `total_epochs`, `loss`, `best_pck`, and an `eta_seconds`; these map onto the
+`TrainMetrics`/`TrainingStatus` fields already populated by the loop
+(`training_api.rs:1251`, `train/src/trainer.rs:43,64`).
+
+### 5.5 Dashboard honesty (both configurations)
+
+- **Enabled build:** button POSTs `/api/v1/train/start`, then opens
+  `/ws/train/progress`; the UI renders live epoch/loss/eta and a terminal
+  success/failure with the output `.rvf` path.
+- **Disabled build:** `/api/v1/train/start` returns a structured
+  `{"enabled": false, "reason": "...", "cli": "wifi-densepose train-room"}` and the
+  button renders disabled with a tooltip — no silent `success:true`.

+- [x] Replaced `training_status`/`training_config` with `training_state:
+      training_api::TrainingState` + `training_progress_tx: broadcast::Sender<String>`.
+- [x] Updated state init; the only readers of the old fields were the stub handlers (deleted).
+- [x] Added `mod training_api;` (+ `mod path_safety;`); the module compiles against the real state.
+
+### P2 — Wire the router, delete the stubs
+- [x] Removed `train_start`/`train_stop`/`train_status` and their 3 route mounts.
+- [x] `.merge(training_api::routes())` — merged **before** `.with_state(...)` (not after).
+      The RuField surface merges after because it carries a *different* state; the training
+      router shares `SharedState`, so merging before is what puts `/api/v1/train/*` under the
+      same `/api/v1/*` bearer gate as everything else.
+- [x] `/api/v1/train/*` and `/ws/train/progress` resolve (verified by HTTP tests, not 404).
+
+### P3 — Confirm the real job streams and produces a model
+- [x] The spawned job loads `.csi.jsonl` (falls back to a `frame_history` snapshot),
+      runs the gradient-descent loop, and writes a `.rvf` under `data/models`.
+- [x] Progress frames carry `epoch`, `total_epochs`, `train_loss`, `val_pck`, `eta_secs`.
+- [x] Server-vs-CLI semantics documented as **intentionally divergent** (§4.2, §9.2):
+      the server runs the light pure-Rust specialist trainer; heavy MAE/LoRA stays CLI.
+
+### P4 — Auth & path safety
+- [x] `/api/v1/train/*` sits under the existing `RUVIEW_API_TOKEN` bearer gate (merged
+      before `.with_state`); `/ws/train/progress` is intentionally **ungated**, matching
+      `/ws/sensing` (browsers can't attach an `Authorization` header to a WS upgrade).
+- [x] `dataset_ids` resolved via `path_safety::safe_id` before file open; pinned by
+      `load_recording_frames_rejects_path_traversal`.
+- [x] Single-job guard: `spawn_training_job` rejects a second start while active
+      (`is_active()` → `active_error`).
+
+### P5 — Dashboard honesty (fallback guarantee)
+- [x] Enabled build: `TrainingPanel` opens `/ws/train/progress` before the POST and renders
+      live epoch/loss/PCK/ETA + a terminal Complete state (already wired; verified).
+- [x] Disabled build (`RUVIEW_DISABLE_SERVER_TRAINING`): start returns
+      `{enabled:false, cli:"wifi-densepose train-room"}` HTTP 409; the dashboard reads
+      `enabled` off `/api/v1/train/status` and disables the Start buttons with a CLI
+      tooltip — no silent no-op. Implemented via a runtime flag rather than a Cargo feature
+      so the `--no-default-features` test build keeps training ON (§9.4 resolved this way).
+
+### P6 — Tests & witness
+- [x] Live-socket test `ws_train_progress_live_101_and_frame`: genuine 101 handshake + a real
+      progress frame after POST start. Plus `ws_train_progress_route_is_wired_not_404`.
+- [x] `http_train_start_produces_model_and_streams`: POST start → poll status → `.rvf` exists.
+- [x] CHANGELOG updated. README/CLAUDE have no training route table, so no route-table edit
+      was needed there.
+
+*(All phases complete. Acceptance criteria verified below — this ADR is Accepted.)*
+
+---
+
+## 7. Acceptance criteria (concrete verification)
+
+All must pass before ADR-186 is Accepted:
+
+- [x] **Orphan is reconnected:**
+      `grep -rn "mod training_api" v2/crates/wifi-densepose-sensing-server/src/`
+      returns a hit (`main.rs`), and
+      `cargo build -p wifi-densepose-sensing-server` **compiles** (proves the state
+      reconciliation in §5.1 is correct — the module cannot compile against the
+      current `AppStateInner`). **VERIFIED.**
+- [x] **Route no longer 404s (HTTP upgrade):** verified in-process rather than with a live
+      `curl` — `ws_train_progress_live_101_and_frame` binds the training router on a real
+      socket and `tokio_tungstenite::connect_async` completes a genuine **101** handshake
+      (asserts `resp.status() == 101`); `ws_train_progress_route_is_wired_not_404` also
+      confirms the route is reached (426 under `oneshot`, **not** 404). **VERIFIED.**
+- [x] **Progress actually streams:** `ws_train_progress_live_101_and_frame` connects the WS,
+      POSTs `/api/v1/train/start`, and receives a real `{"type":"progress","data":{...}}`
+      frame within the 10 s ceiling. **VERIFIED.**
+- [x] **A model is produced:** `http_train_start_produces_model_and_streams` POSTs start,
+      polls `/api/v1/train/status` to completion, and asserts a **new `.rvf`** appeared under
+      `data/models/` (snapshot diff). Also covered by the trainer-level
+      `training_job_streams_real_progress_and_writes_model`. **VERIFIED.**
+- [x] **No silent no-op remains:** `http_train_start_disabled_returns_structured_409` sets
+      `RUVIEW_DISABLE_SERVER_TRAINING` and asserts POST start returns **HTTP 409** with
+      `{"enabled":false, ...,"cli":"wifi-densepose train-room"}` and never `success:true`.
+      **VERIFIED.**
+- [x] **Auth honored:** `/api/v1/train/*` is merged into the router **before** the
+      `RUVIEW_API_TOKEN` bearer middleware and `.with_state`, so it is covered by the exact
+      same `/api/v1/*` gate as every other authenticated route (verified by construction /
+      code review; `/ws/train/progress` is intentionally ungated like `/ws/sensing`). No new
+      dedicated runtime token test was added — the gate is the shared, already-tested
+      `bearer_auth` middleware. **VERIFIED (by construction).**
+- [x] **Path safety:** `load_recording_frames_rejects_path_traversal` asserts
+      `dataset_ids:["../../etc/passwd"]` yields no frames (rejected by `path_safety::safe_id`
+      before any file open). **VERIFIED.**
+- [x] **Integration test green:** `ws_train_progress_live_101_and_frame` (`#[tokio::test]`)
+      serves the training router, opens `/ws/train/progress`, and asserts a 101 upgrade + a
+      real progress frame — and, being built on `training_api::routes()`, cannot compile if
+      the module is orphaned again. **VERIFIED.**
+- [x] **Workspace regression:** `cargo test -p wifi-densepose-sensing-server
+      -p wifi-densepose-train --no-default-features` — sensing-server bin **217 passed /
+      0 failed**, all train suites **0 failed**. A full `cargo test --workspace
+      --no-default-features` run initially surfaced a **test-only parallelism race** in the
+      new tests (two model-writing tests deleted `.rvf`s by directory-diff, occasionally
+      removing a file a third test asserted existed) — fixed by removing the cross-test
+      deletions (each test cleans only its own artifact; `data/models` is gitignored).
+      Re-verified post-fix: `cargo test --workspace --no-default-features` — **0 failed**
+      (exit 0). **VERIFIED.**
+
+---
+
+## 8. Consequences
+
+### Positive
+- Closes issue #1233: the dashboard button either trains-and-streams or honestly says
+  "use the CLI" — the silent no-op is gone in every configuration.
+- Reclaims 1,860 lines of already-written, already-committed trainer that were dead
+  (uncompiled) code, and adds a test that keeps them wired.
+- `/ws/train/progress` gives the UI real epoch/loss/eta, matching the maintainer's
+  stated intent.
+- Forces the state-shape reconciliation that the orphan implied but never landed,
+  removing a latent "two competing training designs" trap in `AppStateInner`.
+
+### Negative
+- Editing `AppStateInner` (`main.rs:1024`) and the router (`main.rs:8068`) touches the
+  large `main.rs`; merge-conflict risk with concurrent work on the same file (the
+  ADR-166 decomposition is relevant here).
+- Adds a live training code path to the server's attack surface — mitigated by the
+  bearer gate and `path_safety`, but it must be reviewed (network/hardware boundary,
+  per the pre-merge security checklist).
+- Server and CLI now have two trainers that must be kept semantically consistent, or
+  their divergence explicitly documented.
+
+### Neutral
+- Heavy MAE/LoRA/`tch` training remains CLI-only; the server streams only the
+  light pure-Rust specialist trainer. Streaming heavy runs is deferred.
+- The progress event schema (`epoch/loss/best_pck/eta`) is already emitted by the
+  orphan; no new schema is invented, only confirmed and documented.
+
+---
+
+## 9. Open questions
+
+1. **WS auth policy for `/ws/train/progress`:** gate it whenever `RUVIEW_API_TOKEN`
+   is set (like `/api/v1/*`), or leave it open like `/ws/sensing`? *Tentative: gate
+   it — training reads recordings and writes models.*
+2. **Server ↔ CLI trainer parity:** should the in-server trainer and
+   `wifi-densepose train-room` (ADR-151) share one code path, or remain deliberately
+   separate (server = quick UI-driven specialist fit; CLI = full bank + geometry
+   conditioning)? *Tentative: keep separate, document the split, share feature
+   extraction where cheap.*
+3. **Heavy-training progress:** can a CLI-launched `wifi-densepose-train` (`tch`)
+   run register itself so `/api/v1/train/status` and the WS can report on it without
+   hosting it in-process? *Tentative: out of scope here; a follow-on ADR.*
+4. **Feature-flagging server training:** should in-server training be behind a Cargo
+   feature (off on the lightweight appliance image), making the P5 disabled-button
+   path the default there? *Tentative: yes — flag it; default the UI to the honest
+   disabled state on images without recordings.*

+
+---
+
+## Context
+
+Two open GitHub issues are, at root, the same complaint: the project's public surface
+lets a reader believe a WiFi→17-keypoint pose model exists and produces real accuracy,
+when the specific code they land on cannot back that claim.
+
+- **#509** — a detailed technical review states: *"While the network architecture for
+  DensePoseHead is defined in the code, there are no pre-trained weights (.pth or .onnx
+  files) available in the repository,"* and questions whether ESP32 1×1 SISO antennas
+  can match the multi-antenna NIC research this project is inspired by.
+- **#1125** — a user asks for anyone to testify the project actually runs and returns
+  real data. A pure credibility complaint.
+
+This ADR follows the **prove-everything / anti-"AI-slop"** directive and the
+**honest-labeling** precedent set by ADR-160: the fix is to make the labels TRUE, not
+to fabricate a capability. Grading vocabulary (from ADR-152 / ADR-160):
+
+- **MEASURED** — reproduced in this worktree; the file/absence was directly inspected.
+- **DATA-GATED** — a real code path exists; honestly flagged where the accuracy is not validated.
+- **NO-ACTION (already-honest)** — audited, found correct, cited as a positive.
+
+### What the investigation actually found (MEASURED in this worktree)
+
+The situation is **more nuanced than either issue implies** — worse in one place, and
+distinctly *better* in others. Forcing a uniformly negative narrative would itself be
+dishonest. The findings:
+
+**1. `archive/v1` — the issue reporter is correct here.**
+- `archive/v1/src/models/densepose_head.py` defines `DensePoseHead` (segmentation +
+  UV-regression heads). Its `_initialize_weights()` uses **`kaiming_normal_` random
+  initialization only** — there is no checkpoint-loading path in the class.
+- `Glob archive/v1/**/*.{pth,onnx,safetensors,pt,ckpt,bin}` → **zero files**. There are
+  **no trained weights anywhere under `archive/v1/`.** The "architecture defined, no
+  weights" claim is TRUE for this tree.
+- `archive/v1/README.md` calls the tree "the legacy Python implementation" in a single
+  closing note but does **not** loudly warn users off it, and there is **no
+  `archive/v1/DEPRECATED.md`.** This is the dead-but-present code that shows up in greps
+  and search and reads as if it were the live implementation.
+- Per ADR-117, this exact tree is the source of the tombstoned pip package
+  `wifi-densepose 1.x` (1.99.0 raises an `ImportError` telling users to migrate). The
+  code is already tombstoned *on PyPI* but not *in the repo*.
+
+**2. `v2` (the current, maintained system) — real weights DO exist; the "no weights
+anywhere" reading is FALSE at the project level.** Git-tracked, committed checkpoints:
+- `v2/crates/cog-pose-estimation/cog/artifacts/pose_v1.safetensors` (507 KB) +
+  `pose_v1.onnx` (12 KB) + `train_results.json` — a **real committed 17-keypoint
+  model**, trained with Candle on an RTX 5080.
+- `v2/crates/cog-person-count/cog/artifacts/count_v1.{safetensors,onnx}` — a committed
+  person-count model.
+- Externally published on Hugging Face (not committed, but real and released):
+  `ruvnet/wifi-densepose-pretrained` (CSI encoder + presence head, honestly re-labeled
+  at **82.3% held-out temporal-triplet accuracy** — the older "100% presence" figure was
+  already retracted, an existing honest-labeling win) and `ruvnet/wifi-densepose-mmfi-pose`
+  (a pose model reporting **82.69% torso-PCK@20** on the MM-Fi `random_split` protocol).
+- ADR-152 measurement (a): the *external* WiFlow-STD (DY2434) model was reproduced at
+  **96.09% PCK@20** on an RTX 5080 (graded MEASURED-EQUIVALENT). That is an external
+  baseline, not RuView's own weights.
+
+**3. The honest gap is narrow and specific — the live, on-device ESP32 17-keypoint
+pose path.** Per `v2/crates/cog-pose-estimation/cog/README.md` (already an exemplary
+"Honest reading" section):
+- The committed `pose_v1` scores **PCK@20 = 3.0% / PCK@50 = 18.5%** on a 217-sample
+  holdout — **below the ADR-079 target of PCK@20 ≥ 35%.** It learns coarse structure
+  (`r_hip` 77% PCK@50) but distal/face joints are near-random. `encoder_init` was
+  `random`; it was trained on a single 30-min seated-at-desk recording (1,077 samples,
+  avg confidence 0.44).
+- The cog's **runtime inference path is still a centred-skeleton stub returning
+  `confidence=0`** — the `pose_v1.safetensors` weights are not yet wired into
+  `src/inference.rs`.
+- ADR-079 records the proxy-supervised baseline at **PCK@20 = 2.5%**, and ADR-152
+  **retracted** the internal camera-supervised 92.9% PCK@20 figure (it was a
+  constant-output model scored under an absolute threshold on near-static frames; a mean
+  predictor scores 100% under the same broken protocol).
+
+### The real problem to fix
+
+Not "the project has no weights" (false) and not "there is a validated pretrained
+DensePoseHead" (false for the live ESP32 path). The real problem is a **labeling and
+navigation gap**:
+1. `archive/v1`'s random-init `DensePoseHead` is indistinguishable, to a grepping
+   reader, from the live implementation, and carries no deprecation notice.
+2. Nowhere is the split stated plainly: *which* checkpoints are real and validated
+   (presence 82.3%, MM-Fi pose 82.69% torso-PCK@20), *which* are real-but-weak and
+   honestly labeled (`pose_v1` 3% PCK@20, runtime stubbed), and *which* are
+   architecture-only with no weights at all (`archive/v1` `DensePoseHead`).
+
+## Decision
+
+Two coordinated honest-labeling actions. Neither invents a capability; both make the
+public surface match what the code and checkpoints actually deliver.
+
+### (a) Formally deprecate `archive/v1` in the repo — MEASURED gap, proposed fix
+
+- **Add `archive/v1/DEPRECATED.md`** — a loud tombstone stating that `archive/v1` is the
+  original pure-Python implementation, is **unmaintained and superseded**, that its
+  `DensePoseHead` is **architecture-only with random-initialized weights and ships no
+  trained checkpoint**, and that the maintained path is the `v2/` Rust workspace + the
+  `wifi-densepose 2.x` / `ruview` pip wheel (ADR-117). Mirror the disclaimer tone of
+  ADR-160's `//!` headers and the pip 1.99.0 tombstone text.
+- **Prepend a loud notice to `archive/v1/README.md`** (the file exists) — a `> ⚠️
+  DEPRECATED` block at the very top pointing to `DEPRECATED.md`, `v2/`, and the pip
+  wheel, before any of the existing "how to install v1" content.
+- **Rule:** no doc outside `archive/v1/` may reference `archive/v1` code (other than the
+  ADR-028 deterministic proof at `archive/v1/data/proof/verify.py`, which is a
+  legitimately live signal-pipeline witness and stays) as if it were current. The two
+  README references verified (`README.md` lines 139/198/204; `docs/user-guide.md`
+  proof/swift-compile lines) are all proof/utility invocations, not implementation
+  claims — they are acceptable and out of scope.
+
+### (b) Model-weights honest labeling — state the three tiers explicitly
+
+Add a **"Model weights: what's real, what's not"** subsection to `README.md` and
+`docs/user-guide.md` that names the three tiers verified above, so no reader can infer
+"a pretrained 17-keypoint DensePoseHead produces real pose accuracy on my ESP32":
+
+| Tier | Checkpoint(s) | Honest status |
+|------|---------------|---------------|
+| **Real & validated** | `ruvnet/wifi-densepose-pretrained` (encoder + presence, 82.3% held-out temporal-triplet); `ruvnet/wifi-densepose-mmfi-pose` (82.69% torso-PCK@20, MM-Fi `random_split`); `count_v1` | MEASURED / published; keep current honest labels |
+| **Real but weak (honestly labeled)** | committed `pose_v1.safetensors` in `cog-pose-estimation` | **PCK@20 = 3.0%**, below the ADR-079 ≥35% target; runtime path is a `confidence=0` stub until weights are wired into `src/inference.rs`. Already disclosed in the cog README; surface the same caveat wherever the live ESP32 pose feature is advertised |
+| **Architecture only, no weights** | `archive/v1` `DensePoseHead` | random-init, no checkpoint; deprecated per (a) |
+
+- The existing MM-Fi/presence honest labels (retraction of "100% presence", the cog
+  "Honest reading") are **NO-ACTION positives** — cite them, do not weaken them.
+- The live ESP32 17-keypoint claim stays **DATA-GATED**: the path to a first
+  *reproducible* on-device baseline is ADR-079 (multi-session, full-body-framed,
+  camera-supervised, ≥30K paired samples at conf ≥0.7, target PCK@20 ≥35%), tracked in
+  [#645]. Do not advertise the live ESP32 pose feature without the "first-cut / below
+  target / runtime stub" caveat until that baseline is MEASURED.
+- Directly answer #509's ESP32-SISO question in the docs, honestly: single-antenna 56-
+  subcarrier CSI at a 20-frame window does **not** carry the fine-grained spatial
+  information the multi-antenna NIC research relies on (the cog README already shows
+  distal/face joints near-random) — the shippable pose accuracy the project *can* stand
+  behind today is the **MM-Fi benchmark** number, not a live single-ESP32 number.
+
+## Phase ledger
+
+| Phase | Action | State |
+|-------|--------|-------|
+| **P0** | This ADR (investigation + decision) | **DONE** (this file) |
+| **P1** | Add `archive/v1/DEPRECATED.md` + loud notice atop `archive/v1/README.md` | **DONE** (1fb5397dd) |
+| **P2** | Add "Model weights: what's real, what's not" tier table to `README.md` + `docs/user-guide.md`; add the caveat wherever the live ESP32 17-keypoint feature is advertised | **DONE** (1fb5397dd; follow-up caveated the hardware table, hero caption, and live-pipeline note) |
+| **P3** | Answer #509's SISO/no-weights question and #1125's "does it run" in `docs/user-guide.md` (point to the reproducible proofs: MM-Fi arena, `archive/v1/data/proof/verify.py`, cog `train_results.json`) | **DONE** (1fb5397dd) |
+| **P4** | Close the DATA-GATED live-pose gap via ADR-079 first reproducible on-device baseline (PCK@20 ≥35%) + wire `pose_v1.safetensors` into `cog-pose-estimation/src/inference.rs` | ACCEPTED-FUTURE ([#645]) |
+
+## Acceptance criteria
+
+- [x] `archive/v1/DEPRECATED.md` exists and names `v2/` + the pip wheel as the maintained path.
+- [x] `archive/v1/README.md` opens with a `> ⚠️ DEPRECATED` block before any install instructions.
+- [x] `README.md` and `docs/user-guide.md` no longer let a reader infer that `archive/v1`
+      or an untrained/random-init `DensePoseHead` produces real pose accuracy without the
+      caveats added here.
+- [x] The live ESP32 17-keypoint pose feature is nowhere advertised without its
+      "first-cut, PCK@20 = 3.0%, below ADR-079 target, runtime stub" caveat.
+- [x] The three real/published checkpoints (presence 82.3%, MM-Fi pose 82.69% torso-PCK@20,
+      `count_v1`) keep their existing honest labels — nothing is weakened or overclaimed.
+- [x] No claim is added that is not MEASURED or explicitly DATA-GATED.
+
+## Consequences
+
+### Positive
+- A grepping reader can no longer mistake `archive/v1`'s random-init `DensePoseHead` for
+  the live system; the dead code is loudly tombstoned in the repo, matching its PyPI 1.99.0 tombstone.
+- #509 and #1125 get an honest, verifiable answer: real trained weights *do* exist
+  (presence + MM-Fi pose are published and benchmarked), the *specific* file the reporter
+  found is architecture-only, and the live ESP32 pose path is honestly weak-and-in-progress.
+- Reinforces the ADR-160 honest-labeling discipline: the project's credibility comes from
+  precise labels, not from a suppressed or inflated narrative.
+
+### Negative
+- The docs must openly state that the live single-ESP32 17-keypoint pose is not yet at a
+  citable accuracy — a short-term "looks less finished" cost, paid for by not overclaiming.
+- Two more files to keep in sync (`DEPRECATED.md`, the tier table) as the checkpoints evolve.
+
+### Neutral
+- No code or model behavior changes; `archive/v1` stays in the tree as a research archive
+  (ADR-117 §1.3) and its ADR-028 proof witness is untouched.
+- Purely documentation/labeling; no crate, wheel, or firmware rebuild required.
+
+## References
+

+# ADR 260: RuField Multimodal Field Sensing Specification
+
+Status: Accepted — v0.1 reference stack
+
+Date: 2026 06 14
+
+Deciders: rUv
+
+Tags: sensing, rf, csi, cir, bfld, radar, ultrasonic, infrared, quantum sensing, privacy, provenance, ruvector, ruview
+
+## 1. Context
+
+RuView proved that commodity wireless signals can be used as a practical sensing substrate. The next opportunity is larger: define a common specification for multimodal ambient sensing across RF, ultrasonic, subsonic, infrared, radar, and future quantum sensors.
+
+Existing standards are valuable but fragmented.
+
+IEEE 802.11bf 2025 standardizes WLAN sensing at the WiFi MAC and PHY layers and was published on September 26, 2025. It is important, but it is WiFi specific.
+
+Bluetooth Channel Sounding standardizes techniques for obtaining phase and time delay information, but Bluetooth SIG explicitly does not define the distance algorithm. That leaves application level interpretation open.
+
+IEEE 802.15.4z HRP UWB supports secure ranging using scrambled timestamp sequence waveforms, but UWB remains one modality rather than a universal sensing grammar.
+
+Matter is a useful smart home interoperability protocol, but it is a device connectivity layer, not a multimodal field sensing specification.
+
+The gap is clear: there is no open specification that normalizes sensor observations across CSI, CIR, BFLD, radar, ultrasound, subsonic vibration, thermal infrared, and quantum field sensing into one privacy aware, provenance rich, fusion ready event model.
+
+## 2. Decision
+
+Create **RuField MFS**, the RuField Multimodal Field Sensing Specification.
+
+RuField MFS will define a common event, tensor, calibration, confidence, privacy, and provenance model for ambient field sensing.
+
+It will not replace IEEE 802.11bf, Bluetooth Channel Sounding, UWB, Matter, radar protocols, or device vendor APIs.
+
+It will sit above them.

+
+## 3. Name
+
+Preferred name: `RuField MFS`
+
+Full name: `RuField Multimodal Field Sensing Specification`
+
+Public positioning: `The open specification for camera free field intelligence.`
+
+## 4. Problem Statement
+
+Modern sensing systems are locked into modality specific silos: CSI systems produce channel matrices; radar produces range Doppler bins; UWB produces range and time of flight; Bluetooth Channel Sounding produces phase and timing primitives; infrared produces thermal arrays; ultrasonic produces acoustic echoes; subsonic produces structural vibration signatures; quantum sensors produce magnetic, inertial, or optical field traces.
+
+Each has different sampling, calibration, confidence, privacy, and provenance semantics. This prevents reliable fusion and makes governance weak because raw sensing, derived sensing, biometric inference, and anonymous occupancy are often mixed without explicit boundaries.
+
+## 5. Goals
+
+1. Define a common multimodal sensing event format.
+2. Define a field tensor format spanning time, frequency, phase, amplitude, range, velocity, angle, temperature, vibration, and uncertainty.
+3. Define a modality registry for RF, acoustic, infrared, radar, and quantum sensing.
+4. Define privacy classes for raw waveforms, derived features, occupancy, anonymized aggregate state, and biometric inference.
+5. Define calibration receipts and provenance hashes.
+6. Define fusion rules for multimodal inference.
+7. Provide a Rust reference implementation.
+8. Provide benchmark tasks for camera free room intelligence.
+9. Make RuView one adapter inside a larger open sensing architecture.
+
+## 6. Non Goals
+
+1. Do not define a new wireless PHY.
+2. Do not replace IEEE 802.11bf.
+3. Do not replace Bluetooth Channel Sounding.
+4. Do not replace UWB secure ranging.
+5. Do not define medical diagnosis.
+6. Do not transmit speech, images, or raw biometric identity by default.
+7. Do not require cloud inference.
+8. Do not require expensive hardware.
+
+## 7. Core Abstraction — the Field Event
+
+A Field Event is a timestamped observation from any ambient field sensor.

+|   15 | synthetic_sim        | simulator or replay source              |
+
+## 9. Field Tensor
+
+The normalized numeric container (`Modality`, `FieldAxis`, `FieldTensor`) as specified in the implementation crate `rufield-core`.
+
+## 10. Privacy Classes
+
+| Class | Description                      | Example                         |
+| ----- | -------------------------------- | ------------------------------- |
+| P0    | Raw waveform or raw sensor frame | raw CSI, raw radar cube         |
+| P1    | Derived non identity features    | Doppler peak, thermal blob      |
+| P2    | Occupancy and motion only        | person present, bed exit        |
+| P3    | Anonymous aggregate state        | room count, zone activity       |
+| P4    | Biometric or health inference    | breathing, gait, sleep, scratch |
+| P5    | Identity linked inference        | named person state              |
+
+Default system policy: edge storage may retain P0 only temporarily; network transmission defaults to P2 or lower; P4 requires explicit consent; P5 requires explicit identity binding and audit log.
+
+## 11. Provenance Receipt
+
+Every event must be auditable (`ProvenanceReceipt`). Acceptance invariant: **No fused inference is valid unless every contributing event has a provenance receipt or is explicitly marked synthetic.**
+
+## 12. Fusion Graph
+
+Nodes: sensor, event, field_tensor, feature, object, zone, state, inference, receipt.
+Edges: observed_by, derived_from, calibrated_by, supports, contradicts, fused_into, expires_at, requires_consent.
+
+## 13. Fusion Rule Format
+
+Human readable TOML rules (`rule.person_present`, `rule.bed_exit`, `rule.nocturnal_scratch`) with `inputs`, `method`, `threshold`, `privacy_max`, optional `window_ms` and `requires_consent`.
+
+## 14. Reference Architecture
+
+Layer 0 physical sensors; Layer 1 native adapters; Layer 2 field tensor normalization; Layer 3 RuVector field embeddings; Layer 4 fusion graph; Layer 5 policy and privacy guard; Layer 6 application event stream; Layer 7 dashboard, API, MCP, Matter bridge.
+
+## 15. Rust Crate Layout
+
+`rufield-core`, `rufield-schema`, `rufield-adapters`, `rufield-fusion`, `rufield-privacy`, `rufield-provenance`, `rufield-bench`, `rufield-viewer`.
+
+## 16. Core Rust Interfaces
+
+`FieldAdapter`, `FieldEncoder`, `FusionEngine`, `PrivacyGuard` traits as specified in `rufield-core`.
+
+## 17. MVP Adapters
+
+v0.1 must support three real modalities: WiFi CSI, mmWave radar, Infrared thermal. Optional: ultrasonic, subsonic, synthetic simulator.
+
+## 18. Benchmark Suite
+
+| Task                    |   Metric |       Target |
+| ----------------------- | -------: | -----------: |
+| Presence detection      |       F1 |         0.90 |
+| Room transition         |       F1 |         0.85 |
+| Bed exit                |       F1 |         0.90 |
+| Breathing detected      |       F1 |         0.80 |
+| Nocturnal scratch       |       F1 |         0.75 |
+| Fall like event         |   Recall |         0.95 |
+| False alarm rate        | per hour |   below 0.10 |
+| Event latency           |      p95 | below 100 ms |
+| Provenance coverage     |  percent |          100 |
+| Privacy violation count |    count |            0 |
+
+## 19. First Viral Demo
+
+Camera free room intelligence: person enters, sits, breathing detected, sleeps, scratches arm, exits bed, leaves room — no camera, no identity, signed field receipts, live fusion graph, privacy class visible per event.
+
+## 20. Data Model
+
+`FieldEvent { spec_version, event_id, timestamp_ns, sensor, tensor, observation, provenance }` and `Observation { zone_id, space_cell, range_m, velocity_mps, motion_vector, confidence, labels, privacy_class }`.
+
+## 21. Decision Matrix
+
+| Option                                        | Interop | Novelty | Buildability | Business value | Risk | Score |
+| --------------------------------------------- | ------: | ------: | -----------: | -------------: | ---: | ----: |
+| Extend RuView only                            |       2 |       2 |            5 |              3 |    2 |    14 |
+| Build proprietary fusion engine               |       3 |       3 |            4 |              4 |    3 |    17 |

+| Attempt new hardware standard                 |       5 |       5 |            1 |              4 |    5 |    20 |
+
+Decision: **Create open RuField spec plus reference stack.** It maximizes credibility, extensibility, and ecosystem pull while avoiding the impossible burden of defining a new physical layer.
+
+## 22. Security Model
+
+| Threat                              | Impact                          | Mitigation                             |
+| ----------------------------------- | ------------------------------- | -------------------------------------- |
+| Raw waveform leakage                | privacy breach                  | P0 edge only by default                |
+| Biometric inference without consent | legal and trust risk            | P4 consent gate                        |
+| Sensor spoofing                     | false occupancy or safety event | signed sensor receipts                 |
+| Replay attack                       | forged event stream             | nonce plus timestamp plus hash chain   |
+| Model drift                         | wrong inference                 | calibration expiry and benchmark gates |
+| Overfitting to one room             | weak generalization             | room split benchmark                   |
+| Vendor firmware change              | silent degradation              | firmware hash in receipt               |
+
+## 23. Calibration Model
+
+`CalibrationReceipt` is first class. Required calibration tasks: empty room baseline, single person walk path, sit and stand, bed or couch transition, breathing reference, no motion stability period.
+
+## 24. Inference Semantics
+
+Every inference must include: label, confidence, supporting events, contradicting events, privacy class, calibration id, model id, expiry time.
+
+## 25. Consequences
+
+Positive: RuView becomes part of a larger sensing ecosystem; the spec creates a standards-style wedge without waiting for silicon vendors; multimodal fusion becomes portable; privacy and provenance become differentiators; enterprise deployment becomes easier to justify; benchmark receipts reduce skepticism.
+
+Negative: broad scope can dilute execution; hardware variability will be painful; calibration is the hardest practical problem; some will claim existing standards already solve parts of this; medical and biometric use cases require careful governance.
+
+Mitigation: keep v0.1 narrow; ship real adapters; publish benchmark receipts; do not claim medical diagnosis; position RuField above existing standards.
+
+## 26. Implementation Plan
+
+Phase 1 spec skeleton; Phase 2 Rust core; Phase 3 adapters; Phase 4 fusion graph; Phase 5 dashboard; Phase 6 benchmark.
+
+## 27. Acceptance Criteria
+
+v0.1 is accepted when:
+
+1. Three modalities stream into one event graph.
+2. Every event has a privacy class.
+3. Every event has a provenance receipt.
+4. Fusion produces at least five room state inferences.
+5. p95 event pipeline latency is below 100 ms.
+6. Benchmark runner produces deterministic reports.
+7. Raw waveform storage is disabled by default.
+8. P4 inference requires consent policy approval.
+9. Dashboard shows live camera free room intelligence.
+10. Spec is readable enough for external implementers.
+
+## 28. Reference Repository Structure
+
+Crates under `v2/crates/rufield-*` (workspace members), spec under `docs/rufield/`, benches under `rufield-bench`.
+
+## 29. Open Questions
+
+1. JSON Schema first, Protobuf first, or both?
+2. Default transport: MQTT, NATS, WebSocket, or MCP?
+3. Matter integration: bridge or first class target?
+4. P4 health inference disabled by default in public demos?
+5. Benchmark datasets synthetic first, then real world?
+6. Include quantum modality IDs even if adapters are synthetic only?
+
+## 30. Recommendation
+
+Proceed. Publish RuField as an open specification with a working Rust reference stack and a viral camera free room intelligence demo.
+
+## 31. Benchmark Acceptance Test
+
+```text
+Given a room with WiFi CSI, mmWave radar, and thermal IR sensors
+When a person enters, sits, breathes, exits bed, and leaves
+Then RuField emits signed events
+And classifies room state without a camera
+And keeps all default network events at P2 or below
+And produces p95 latency below 100 ms
+And produces a deterministic benchmark report
+```
+
+---
+
+## Implementation Status (v0.1 reference stack)
+
+The v0.1 reference stack is implemented as a **standalone Cargo workspace**
+(`rufield/`, published as `github.com/ruvnet/rufield` and vendored into RuView
+as a submodule — the `vendor/rvcsi` pattern). It is pure Rust, builds and tests
+on Windows with no native deps (`ndarray`/`tch`/`openblas` are not used), and
+depends only on `serde`, `serde_json`, `toml`, `sha2`, and `ed25519-dalek`.
+
+**All metrics below are SYNTHETIC.** They are scored against the simulator's own
+ground-truth labels. They demonstrate the pipeline recovers known truth and runs
+within latency/privacy/provenance budgets — they are **not** field-validated
+accuracy. There is no hardware in v0.1; real adapters (ESP32 CSI, mmWave, thermal
+IR) are a documented follow-up (see the repo README "Firmware" section).
+
+### Crates delivered
+
+| Crate | Implements |
+|-------|-----------|

+| `rufield-provenance` | Real `sha256` content hashing + deterministic `ed25519` sign/verify; §11 `is_fusable` invariant. Tests: tamper → verify fails; synthetic event fusable without signer. |
+| `rufield-privacy` | §10 default policy + `DefaultPrivacyGuard` (`authorize` → Allow/Deny/RequiresConsent). Tests: P0 transmit denied; P4 no-consent → RequiresConsent; P4 consent → Allow; P2 → Allow; P5 needs identity binding. |
+| `rufield-adapters` | Deterministic seeded `SyntheticSim` emitting the §19 sequence across 3 modalities (wifi_csi, mmwave_radar, infrared_thermal). Same seed ⇒ identical signed event stream with ground-truth labels. |
+| `rufield-fusion` | `FusionGraph` (§12) + `RuFieldFusion` engine; TOML rules (§13, ≥5 inferences: person_present, sitting, sleeping, breathing, nocturnal_scratch, bed_exit, room_transition); weighted-Bayes + temporal-window; rejects non-fusable events; `FieldInference` with §24 fields. |
+| `rufield-bench` | Deterministic runner: F1 per task (SYNTHETIC), p95 latency, provenance coverage, privacy violations; JSON + human table; §31 acceptance test as `#[test]`. |
+
+Total test count across the workspace: **60 tests, 0 failed**.

+| 1 | Three modalities stream into one event graph | **PASS** — wifi_csi, mmwave_radar, infrared_thermal |
+| 2 | Every event has a privacy class | **PASS** — `Observation.privacy_class` (non-optional), default ≤ P2 |
+| 3 | Every event has a provenance receipt | **PASS** — every event is ed25519-signed and verifies; coverage 100% |
+| 4 | Fusion produces ≥ 5 room-state inferences | **PASS** — 7 distinct inferences produced |
+| 5 | p95 event pipeline latency < 100 ms | **PASS** — p95 ≈ 0.01 ms (in-process) |
+| 6 | Benchmark runner produces deterministic reports | **PASS** — identical report across runs (latency is the only wall-clock field) |
+| 7 | Raw waveform storage disabled by default | **PASS** — P0 network transmission denied by default policy |
+| 8 | P4 inference requires consent policy approval | **PASS** — P4 without consent → RequiresConsent; breathing/scratch rules carry `requires_consent = true` |
+| 9 | Dashboard shows live camera-free room intelligence | **PASS** — `rufield-viewer` (Axum + vanilla JS) streams the deterministic SyntheticSim→fusion demo: live room state, privacy-badged (P0–P5) event log, fusion graph, click-to-open signed-receipt modal, behind a permanent `SYNTHETIC — simulated sensors, no hardware` banner. `cargo run -p rufield-viewer`. Read-only demo viewer (not a device-management console — that's the real-adapter milestone). |
+| 10 | Spec readable for external implementers | **PASS** — ADR-260 + detailed standalone README with compiling usage examples |
+
+**Decision:** **all §27 criteria 1–10 PASS** (criterion 9, the live dashboard,
+was completed by `rufield-viewer`). Status is **Accepted — v0.1 reference stack**.

+
+All five scored §18 tasks meet their F1 targets **on synthetic ground truth**.
+`nocturnal_scratch` is 0.923 (one borderline noise tick at this seed) — reported
+honestly rather than tuned to 1.0. The fall-like / false-alarm-rate §18 rows are
+not scored in v0.1 (no fall is in the demo sequence) and are a follow-up. These
+numbers prove the fusion pipeline scores correctly against known truth; they say
+**nothing** about real-world accuracy, which requires the hardware adapters that
+v0.1 deliberately does not ship.
+
+### Honest statement
+
+Every metric here is simulator-based. No ESP32 CSI, mmWave, or thermal capture
+was used. RuField v0.1 is a working, honestly-measured reference pipeline —
+data model, provenance, privacy, fusion, and a deterministic benchmark — pending
+real hardware adapters.

+- The HNSW index ships a **committed recall@10 correctness gate** (≥ 0.95 vs brute force on a planted-cluster fixture). Low recall means a graph bug; the gate is wired to fail in that case. It **did** fail first — and caught a real index-out-of-bounds bug in the insert path (§4) — which is exactly what a real gate is for.
+- Every QPS/recall number below is **MEASURED** on this box with a committed, deterministic, `--no-default-features`-runnable measurement (`src/ann_measure.rs`, `ann_bench_report`) and a committed criterion bench (`benches/ann_bench.rs`). Both call **one** shared fixture/measurement module, so the bench and the report can never measure different graphs.
+- The **headline result is an honest negative**: at our test scale the SymphonyQG-style quantized variant **does not beat float HNSW at equal recall** — the 1-bit Hamming traversal is too coarse to keep recall up. We report the real numbers, explain *why*, and state the expected large-N crossover. **We did not tune the quantized path to manufacture the 3.5–17× the source claims.** A measured negative + a scale caveat is a valid, publishable result.
+- We are explicit that this is **OUR HNSW + OUR 1-bit quantization, not SymphonyQG's exact system**. It tests the **direction** of the claim on our hardware/data, not a 1:1 reproduction.
+
+Test machine: Windows 11, `cargo test --release`, `std::time::Instant` wall-clock. Numbers are warm medians on this box; the **ratio** is the claim, not the absolute QPS.

+
+## 1. Context
+
+The ruvector crate's retrieval path — AETHER re-ID hot-cache (ADR-024), the `sketch.rs` 1-bit prefilter (ADR-084), room fingerprinting — is, at its core, an **approximate nearest-neighbour (ANN)** problem: dense float embedding in, top-K similar ids out. But **the crate had no graph index**. Every `topk` was either a linear scan (`O(N·d)` per query) or a 1-bit Hamming prefilter over a linear scan. That is `O(N)` per query and does not scale.
+
+[ADR-156 §5 #1](ADR-156-ruvector-fusion-beyond-sota.md) graded **SymphonyQG** (SIGMOD 2025) the **lead beyond-SOTA ANN candidate**, citing the source's claim of **3.5–17× QPS over HNSW at equal recall**, but marked it **CLAIMED**:
+
+> *"author-measured; **not reproduced on our hardware** — reproduction is future work."*
+
+And ADR-156 §8 was blunt about *why* it could not be reproduced: **there was no HNSW baseline to compare against.** You cannot measure a ratio against a baseline that does not exist. This ADR builds that missing baseline, builds the quantized variant that tests the direction of the SymphonyQG bet, and measures the real ratio.
+
+---
+
+## 2. Decision
+
+1. Add a correct, dependency-free **float HNSW** graph index (`hnsw.rs`): the real Malkov & Yashunin (TPAMI 2018) algorithm — multi-layer navigable small-world graph, `ef_construction` / `ef_search`, the Algorithm-4 neighbour-selection heuristic, seeded-deterministic level assignment, L2 + cosine. This is the **baseline** ADR-156 said was missing.
+2. Add a **SymphonyQG-style quantized-traversal variant** (`hnsw_quantized.rs`): the *same* graph (same seed, same structure), but the beam search scores candidates with a **cheap 1-bit Hamming distance** over the RaBitQ Pass-2 rotated sign code (reusing `rotation.rs` + the sign-quantization of `sketch.rs`), then **exact-float reranks** the final candidate set. This is the SymphonyQG bet — cheaper per-node scoring, recovered by a final exact rerank.
+3. **Measure** linear vs float-HNSW vs quantized-HNSW (recall@10, QPS, equal-recall ratios) on one deterministic planted-cluster fixture, and record the honest verdict against the SymphonyQG 3.5–17× claim.
+
+### Why 1-bit Hamming for the quantized traversal
+
+The crate already had the exact pieces SymphonyQG fuses: a deterministic orthogonal rotation (`rotation.rs`, RaBitQ Pass-2) and sign-quantization (`sketch.rs`). A 1-bit code compares by POPCNT Hamming — a few machine words, no per-dimension float work — so it is the cheapest possible traversal score and the most direct test of "can a quantized score keep the beam on the right path." The cost (measured below): the 1-bit code is a *coarse* angle proxy (ADR-156 §10 measured ~46% strict-K coverage for sign-only), and that coarseness is what limits recall here.
+
+---
+
+## 3. Design
+
+### 3.1 `hnsw.rs` — float HNSW (the baseline)
+
+- **Graph.** `links[id][layer]` adjacency; layer 0 holds every node, higher layers exponentially sparser. `m_max` is `2·M` on layer 0, `M` above (the paper's asymmetric degree cap).
+- **Insert.** Greedy-descend the upper layers to a good entry point, then for each layer from the node's level down to 0: `search_layer` for `ef_construction` candidates, `select_neighbours` (Algorithm 4 — keep a candidate only if it is closer to the new node than to any already-selected neighbour, giving diverse navigable edges), wire bidirectional edges, re-prune any neighbour that overflows `m_max`. The node is pushed into the arrays **before** wiring so every `links[*]` index is valid mid-insert (§4 — the bug the gate caught).
+- **Search.** Greedy-descend layers `>0`, then best-first beam search of width `ef` on layer 0; return the closest `k`. Iterative (explicit heaps + visited set) — **no recursion**, bounded by the beam and the visited set.
+- **Determinism.** Level assignment is the only randomness and is driven by a **seeded SplitMix64** (the exact pattern from `rotation.rs`) — never `Date::now`/OS RNG/unseeded `rand`. Same `(seed, params, insertion order)` ⇒ bit-identical graph and search (pinned by `hnsw_is_deterministic_for_seed`).
+- **Robustness.** Empty index, `k==0`, `k>n`, single node, zero-dim, ragged query, `ef<k` all return cleanly — pinned by `*_no_panic` tests.
+
+### 3.2 `hnsw_quantized.rs` — the SymphonyQG-style variant
+
+Same graph as the float index (identical seed/structure — the **only** variable is the scoring), plus a per-node `ceil(D/8)`-byte 1-bit Pass-2 sign code (`D = next_pow2(dim)`). `search_quantized(query, k, ef, rerank)`:
+1. Encode the query to its 1-bit code (one rotation + sign pack).
+2. Greedy-descend + beam-search the graph scoring every visited node by **POPCNT Hamming** (query-code XOR node-code) — no per-dim float work.
+3. **Exact-float rerank** the top `rerank` Hamming candidates with the true L2/cosine metric, return the best `k`.
+
+### 3.3 Security / robustness
+
+Both indices: bounded **iterative** traversal (no unbounded recursion), no panic on empty/degenerate/ragged/zero-dim input (the metric compares over the shorter prefix; zero-norm cosine returns max distance, not NaN). The 1-bit encode handles padded dims via the existing `Rotation::apply_padded`.
+
+---
+
+## 4. The bug the correctness gate caught (disclosed, not hidden)
+
+The first run of the recall@10 gate **panicked**: `index out of bounds: the len is 33 but the index is 33` in `search_layer`. Root cause: `insert` wired bidirectional edges (`links[nbr][l].push(id)`) **before** pushing the new node's own `links[id]` row into the array. A later traversal step in the *same* insert could hop to a neighbour that now pointed at `id` and read `links[id]` — which did not exist yet. Fix: push the node (with empty per-layer link lists) into `vectors`/`links`/`levels` **up front**, then wire edges into its existing slot. The new node has no incoming edges and empty outgoing lists until wiring, so it is unreachable by the searches that run first — pushing early is safe and keeps every index valid. This is exactly why the recall gate exists: a silent low-recall graph and an out-of-bounds panic are both "slop" the gate forces into the open.
+
+---
+
+## 5. The SymphonyQG claim being tested
+
+| Source | Claim | Grade (before this ADR) |
+|--------|-------|-------------------------|
+| SymphonyQG, SIGMOD 2025 | **3.5–17× QPS over HNSW at equal recall**, via quantization unified with graph traversal, pure-CPU/edge-portable | **CLAIMED** — author-measured, *not reproduced on our hardware (no HNSW baseline existed)* |
+
+The bet: a quantized traversal score is cheap enough — and accurate enough to keep the beam on-path — that you pay far less per visited node and recover the small recall loss with a final exact rerank.
+
+---
+
+## 6. MEASURED results

Graph seed `0x6261524741484E53`, rotation seed `0x5EEDC0DE12345678`. `--release`, warm wall-clock on the test machine. (The fixture and both indices are shared by the criterion bench.)

+| ≥ 0.99 | ef=16 → 25,744 QPS | **none** | — | **25.19×** |
+
+---
+
+## 7. Honest verdict
+
+**The HNSW baseline is a decisive win over linear scan: ~25× QPS at recall ≥ 0.99** (ef=16: 0.9945 recall, 25,744 QPS vs linear 1,022 QPS). The correctness gate (recall@10 ≥ 0.95 vs brute force, both L2 and cosine) holds. This is the baseline ADR-156 §5 #1 said did not exist — it now does.
+
+**The SymphonyQG-style quantized variant does NOT beat float HNSW at our scale — direction REFUTED at N=10k.** The 1-bit Hamming traversal is too coarse: its best achievable recall is **0.738** (ef=256, rr=100), and it never reaches even the 0.90 equal-recall point where a fair QPS comparison could be made. Where the quantized score *is* faster (ef=32: ~30–36k QPS, beating float's 25.7k), its recall collapses to 0.16–0.26 — a meaningless win. There is **no equal-recall operating point** at which quantized is faster, so the SymphonyQG 3.5–17× claim is **not reproduced** by our 1-bit construction here.
+
+**Why** (so the negative is understood, not just stated):
+1. The 1-bit sign code is a **coarse angle proxy** — ADR-156 §10 already measured it at ~46% strict-K coverage. Driving graph *traversal* by that coarse score steers the beam onto the wrong nodes, and the exact-float rerank can only recover what the beam actually visited. At N=10k, near-neighbours have nearly-identical sign codes, so Hamming cannot separate them.
+2. At this scale **float distance is already cheap**: one 128-d L2 is a handful of µs; the per-node float compute the quantization saves is small relative to the recall it costs. SymphonyQG's win shows up at **much larger N** (millions), where (a) the float-distance fraction of query time dominates and (b) their *multi-bit RaBitQ-fused* code (not our 1-bit sign code) keeps recall high. **Expected crossover: large N + a higher-bit code.** ADR-156 §10 already measured that a ≤4-bit code reaches ~74% strict coverage vs 1-bit's ~46%, so a multi-bit traversal score is the obvious next lever — deferred, not claimed.
+
+**Caveat (stated plainly):** this is **our** HNSW + **our** 1-bit quantization, not SymphonyQG's system. We tested the *direction* of the claim ("does quantized traversal + rerank beat float HNSW at equal recall?") on our hardware/data and got a **measured no at N=10k**. That neither confirms nor refutes SymphonyQG's own published numbers on their system/scale — it refutes the direction *for our construction at our scale*, and identifies the two levers (scale, code bit-depth) a real reproduction would need.
+
+---
+
+## 8. Validation
+
+- **`cd v2 && cargo test -p wifi-densepose-ruvector --no-default-features --lib`** — **156 passed / 0 failed, 1 ignored** (M1 added 20: 10 `hnsw`, 7 `hnsw_quantized`, 3 `ann_measure`; M2 added 5 multi-bit/scaling tests; `scaling_report` is the `#[ignore]` measurement that produced the §11 table).
+- **`cargo test --workspace --no-default-features`** — GREEN (see §10 for the count).
+- **Correctness gate verified to bite:** the recall@10 gate **panicked** on the first (buggy) insert path (§4); after the fix it passes at 0.99+ recall (L2 and cosine).
+- **`cargo test -p wifi-densepose-ruvector --no-default-features --release ann_bench_report -- --nocapture`** — prints the §6 table; the numbers above are copied verbatim from that run.
+- **`cargo bench -p wifi-densepose-ruvector --bench ann_bench`** — compiles and runs the same fixture through criterion.
+- **`python archive/v1/data/proof/verify.py`** — **VERDICT: PASS** (the Rust ANN work is independent of the Python signal-proof pipeline; hash unchanged).
+
+---
+
+## 9. Consequences
+
+**Positive.** ruvector now has a real, deterministic, pure-Rust HNSW graph index (25× over linear scan at high recall) usable by the AETHER re-ID / sketch-prefilter path — the ANN substrate ADR-156 §5 #1 wanted. The SymphonyQG claim is no longer CLAIMED-only: we built the missing baseline and **measured** the direction, with the bug-caught-by-the-gate disclosed.
+
+**Negative / honest.** The 1-bit quantized variant is **not** an equal-recall QPS win at our scale; it is shipped as a measured experiment with a clearly-stated ceiling, not as a recommended default. Anyone reaching for it must read §7.
+
+**Resolved by Milestone-2 (§11, MEASURED — no longer deferred).**
+- **Multi-bit traversal score** — implemented (`b ∈ {1,2,4}` bits/dim over the Pass-2 rotated coordinates) and measured. It *does* lift quantized recall (at N=10k, b=4 reaches the 0.90 equal-recall regime where 1-bit could not), but still does not beat float HNSW QPS.
+- **Large-N crossover measurement** — measured at N ∈ {10k, 100k, 250k}. **The predicted large-N crossover did NOT materialize — it moved the wrong way** (quant recall *collapses* as N grows). See §11.
+
+**Deferred (not silently dropped).**
+- **Wiring HNSW into the live re-ID path** (AETHER hot-cache / sketch prefilter) behind a flag.
+- **N ≥ 1M + SymphonyQG's exact RaBitQ-fused construction** — our impl refutes the *direction* at ≤250k; a true 1:1 reproduction at million-scale with their fused codes remains a separate, larger build.
+
+---
+
+## 10. What changed, file by file
+
+- `hnsw.rs` (new) — float HNSW: graph, seeded-deterministic level assignment, Algorithm-2 beam search, Algorithm-4 neighbour selection, L2/cosine, brute-force ground truth, full degenerate-case guards; 10 tests incl. the recall@10 correctness gate (L2 + cosine) and determinism. The insert-order bug fix (§4).
+- `hnsw_quantized.rs` (new) — SymphonyQG-style quantized-traversal index over the shared graph: 1-bit Pass-2 code per node, Hamming-scored greedy + beam, exact-float rerank; 7 tests incl. the rerank-recall gate and determinism.
+- `ann_measure.rs` (new) — shared deterministic fixture + recall/QPS measurement for linear / float-HNSW / quant-HNSW, the `ann_bench_report` test (the §6 source of truth), `ANN_BENCH_N` override.
+- `benches/ann_bench.rs` (new) + `Cargo.toml` `[[bench]]` — criterion bench over the same fixture/indices.
+- `lib.rs` — `pub mod hnsw / hnsw_quantized / ann_measure`; re-export `HnswIndex`, `HnswParams`, `Metric`, `QuantizedHnswIndex`.
+- `ADR-156-ruvector-fusion-beyond-sota.md` §5 #1 + §8 backlog — SymphonyQG regraded **CLAIMED → MEASURED-direction-tested (refuted at N=10k for our 1-bit construction)**, pointing here.
+- `CHANGELOG.md` — `[Unreleased]` entry.
+
+---
+
+## 11. Milestone-2 — multi-bit traversal + large-N scaling study (MEASURED)
+
+M1 (§7) refuted the SymphonyQG direction at N=10k with a 1-bit code, and *predicted* a crossover at "large N + a higher-bit code." M2 builds both levers and measures them — so the prediction is tested, not assumed.
+
+**Built:** `hnsw_quantized.rs` generalized from 1-bit to a **`b`-bit-per-dimension** code (`b ∈ {1,2,4}`, a mid-rise quantizer over the same `RANGE=3.0` rotated coordinates as ADR-156 §10's `measure_multibit`); `ann_measure.rs` gained `run_scaling_study` / `best_float_op` / `best_quant_op` + a deterministic `scaling_report` (`#[ignore]`, `--release`) and a CI-safe `scaling_study_small_is_consistent`. Memory: **16 / 32 / 64 bytes/node** for b = 1 / 2 / 4.
+
+**MEASURED** (dim=128, 64 clusters, 200 queries, K=10, L2, M=16, ef_construction=200, seeded, `--release`, this box; target recall ≥ 0.90):
+
+| N | bits | B/node | quant best recall | float @ target | quant @ target | quant/float |
+|--:|--:|--:|--:|--|--|--:|
+| 10,000 | 1 | 16 | 1.000 | 23,155 QPS @ r=0.995 | 4,482 QPS @ r=0.965 | **0.19×** |
+| 10,000 | 2 | 32 | 1.000 | 23,155 QPS @ r=0.995 | 10,658 QPS @ r=0.908 | **0.46×** |
+| 10,000 | 4 | 64 | 1.000 | 23,155 QPS @ r=0.995 | 11,217 QPS @ r=0.946 | **0.48×** |
+| 100,000 | 1 / 2 / 4 | 16/32/64 | 0.207 / 0.346 / 0.788 | 2,493 QPS @ r=0.938 | none (never ≥ 0.90) | — |
+| 250,000 | 1 / 2 / 4 | 16/32/64 | 0.108 / 0.210 / 0.624 | 1,593 QPS @ r=0.925 | none | — |
+
+**Verdict — NO crossover at any measured (N, b) up to 250k, and the trend REFUTES the large-N prediction:**
+1. **Multi-bit helps at small N but not enough.** At N=10k, more bits lift the equal-recall QPS ratio 0.19× → 0.46× → 0.48× (and let b≥2 actually *reach* the 0.90 bar that 1-bit missed) — but quant stays **below 1.0×**, i.e. slower than float HNSW at equal recall.
+2. **The predicted large-N crossover moved the wrong way.** As N grows 10k → 100k → 250k, quant's best achievable recall **collapses** (b=4: 1.000 → 0.788 → 0.624) and never reaches the 0.90 comparison point, while float HNSW holds ≥0.92. A denser graph packs near-neighbours whose low-bit codes are nearly identical, so the approximate score steers the beam off-path faster than the bigger float-distance savings can repay. The "crossover at millions" intuition is **not supported by our construction's trend** — if anything it diverges.
+3. **Caveat unchanged:** this is our HNSW + our per-node multi-bit code, not SymphonyQG's RaBitQ-fused graph. The result refutes the *direction* for our construction at ≤250k; it does not disprove their published numbers on their system at their scale. A real 1:1 reproduction is the deferred million-scale build.
+
+This is a **published negative with the mechanism explained** — the multi-bit + scaling levers were built and measured rather than asserted, and the honest outcome (no crossover, trend diverging) is recorded, not hidden.
