feat(beyond-sota): ADR-156 M2 — RaBitQ unbiased distance estimator (rigorous published negative on strict-K) (#1056)

* feat(ruvector): RaBitQ unbiased distance estimator (ADR-156 M2)

Implement the real Gao & Long (SIGMOD 2024) RaBitQ contribution on top of
the existing Pass-2 rotation: an unbiased estimator of the inner product /
squared distance recovered from the 1-bit code plus 8 B/vec per-vector side
info (residual_norm + x_dot_o), used to rerank the candidate set instead of
raw Hamming.

- src/estimator.rs (new): EstimatorSketch, SideInfo, EstimatorQuery,
  DistanceEstimator (estimate_inner_product / estimate_sq_distance /
  ranking_key / cosine_ranking_key), EstimatorBank (topk_estimated[_cosine],
  with_centroid). Zero-centroid simplification documented; paper-faithful
  centroid path also built.
- src/rotation.rs: extract apply_padded() (full padded FHT frame the code
  lives in); apply() now truncates apply_padded(). No behaviour change.
- lib.rs: export estimator types.

Additive + backward-compatible: Pass-1 Sketch / Pass-2 SketchBank / WireSketch
wire format unchanged; all external callers use Pass-1 and are unaffected.

* test(ruvector): estimator strict-K coverage harness (ADR-156 M2)

Add measure_estimator (cosine rerank) + measure_estimator_euclidean to the
coverage harness, on the BIT-IDENTICAL fixture / cluster centres / query
stream / cosine ground truth as measure_pass1/measure_pass2 — apples-to-apples
sign-Hamming vs unbiased-estimator-rerank.

Regression tests:
- estimator_rerank_not_worse_than_sign (>= sign-only Pass-2 on a fixed fixture)
- estimator_coverage_is_deterministic
- estimator_coverage_report (--nocapture prints the strict-K table)

MEASURED strict-K (candidate_k=K=8): Pass-1 36.13% -> Pass-2-sign 46.39% ->
estimator-cosine 49.71%. Still short of the ADR-084 90% strict bar; estimator
reaches 95.12% at candidate_k=24 (vs sign 91.60%). Published negative.

* docs(ruvector): record RaBitQ estimator measured negative (ADR-156 §11, ADR-084)

- sketch_bench: estimator cosine/euclid columns in the coverage table.
- ADR-156 §11 (new): estimator formula + zero-centroid simplification stated
  honestly; strict-K coverage table; RESOLVED-NEGATIVE verdict (49.71% strict,
  short of 90%); pinning test names. §5 #2 + §10.5 updated.
- ADR-084 'Pass 2b' (new): estimator landed + measured strict-K vs the bar.

+### Security
+- **ADR-157 Milestone-1 B4 - constant-time HMAC sync-beacon tag compare (`wifi-densepose-hardware`).** `AuthenticatedBeacon::verify` compared the 8-byte HMAC-SHA256 tag with `self.hmac_tag == expected`, which short-circuits on the first differing byte and leaks, through verification latency, how many leading bytes an attacker's forged tag matched - a byte-by-byte tag-recovery oracle (~256*N trials instead of 256^N). Replaced with a hand-rolled branch-free `constant_time_tag_eq` (XOR-accumulate every byte difference into a single `u8`, no early exit, `#[inline(never)]` + `core::hint::black_box` to stop the optimizer reintroducing a short-circuit or a non-constant-time `memcmp`). **No new dependency** - ADR-157 had deferred this only to avoid adding the `subtle` crate; a fixed 8-byte compare needs none. Grade MEASURED (constant-time *construction*; micro-timing on a noisy host is a smoke check only, gated `#[ignore]`). Pinned by `tag_compare_is_constant_time_shape` (equal/first-differ/last-differ/all-differ/length-mismatch + an end-to-end `verify()` last-byte tamper), proven to fail on a last-byte-skipping constant-time bug. ADR-157 §8 B4 -> RESOLVED.
+- **ADR-080 open HIGH findings closed on the Rust `wifi-densepose-sensing-server` boundary (ADR-164 G11).** The QE sweep's three HIGH findings — XFF-spoofing bypass, leaked stack traces, JWT-in-URL (CWE-598) — were logged against the Python v1 API and never re-verified against the shipped Rust sensing-server; the HOMECORE/M7 sweep (ADR-161) covered `homecore-server`, not this crate.
+  - **#2 leaked internal errors (the one live exposure) — FIXED.** Six handlers in `main.rs` serialized the internal error `Display` straight into the JSON response body: `edge_registry_endpoint` returned a panicked `spawn_blocking` `JoinError` (`"task … panicked"`) in a `500`, plus the raw upstream error in a `503`; `delete_model`/`delete_recording`/`start_recording` returned `std::io::Error` strings (OS detail / path); `calibration_start`/`calibration_stop` returned the `FieldModel` error chain. New `error_response` module logs the full detail **server-side only** (with a correlation id) and returns a generic body (`{"error":"internal_error","correlation_id":…}`) — no `panicked`, no file paths, no Debug chain. 5 module tests (a leak-substring guard proven to fail on the reverted old body) + the existing handler suite.
+  - **#1 XFF-spoofing bypass — VERIFIED ABSENT, regression-pinned.** The sensing-server has no XFF-trusting control to bypass: there is no IP-based rate-limiter or IP-allowlist, and neither `bearer_auth` (token-only) nor `host_validation` (Host-header only) reads `X-Forwarded-For`/`X-Forwarded-Host` (no `forwarded`/`peer_addr`/`client_ip` anywhere in the crate). Added regression tests proving a spoofed `X-Forwarded-For` never flips an auth decision and a spoofed `X-Forwarded-Host` never bypasses the Host allowlist.
+  - **#3 JWT-in-URL (CWE-598) — VERIFIED ABSENT, regression-pinned.** `require_bearer` reads the token only from the `Authorization` header; the WebSocket handlers take no token query param and the sole `Query` extractor (`EdgeRegistryParams`) is a non-secret `refresh` flag. Added a regression proving `?token=`/`?access_token=` in the URL never authenticates while the header path still does.
+
+### Fixed
+- **ADR-155 Milestone-1b — metric-definition unification, the §8 backlog subset (Goals A/B/C).** Closed the two §8 metric-integrity items; every change pinned by a test, graded MEASURED. The audit (Goal A) also surfaced findings the §1 table under-counted — recorded honestly in ADR-155 §8.1, not hidden. Workspace stays green; Python proof unchanged (metrics are not on the deterministic proof's signal path).
+  - **Goal B — `test_metrics.rs` now validates the production metric, not a reimplementation.** The integration test previously asserted properties of its OWN local `compute_pck`/`compute_oks` (a test that can't catch a canonical-impl bug — both could be wrong the same way). Hoisted the canonical core (`pck_canonical`/`oks_canonical`/`canonical_torso_size`/sigmas/`bounding_box_diagonal`) into a new **un-gated** `metrics_core` module so the single definition is reachable under `cargo test --no-default-features` (the `metrics` module is `tch-backend`-gated); `metrics` re-exports it → still exactly ONE implementation. Rewrote the test to assert the production `pck_canonical`/`oks_canonical` equal **hand-computed** fixtures (`canonical_pck_matches_hand_computed_fixture` = 3/4 correct ⇒ 0.75; hip↔hip normalizer pin; zero-visible⇒0.0; OKS perfect⇒1.0; fake-Gold pin) plus a differential cross-check (`test_kernel_agrees_with_canonical`: an independent raw-threshold kernel must AGREE with canonical where torso==1.0). `wifi-densepose-train --no-default-features`: test_metrics **10→12**, 0 failed.
+  - **Goal C — divergent live-server PCK/OKS relabelled so they're never conflated with canonical.** Goal C named `training_api.rs:804` (torso-HEIGHT PCK); the audit found that file is an **orphan (not `mod`-declared, does not compile)** and the **real** live `best_pck`/`best_oks` come from `trainer.rs` — a **raw, unnormalized** `pck_at_threshold` and an **`area=1.0` fake-Gold** `oks_map` (both MISSED by ADR-155 §1, both on the claim-inflating side, both serialized as bare "PCK@0.2"/"OKS"). Torso-height/raw math is load-bearing (pixel-space, different scale axis, no `ndarray`/train dep), so the honest fix is **relabel, not force-unify**: `training_api.rs` `compute_pck` → `compute_pck_torso_height` + field/log docs; `trainer.rs` kernels documented raw/fake-Gold; `main.rs` prints `pck_raw@0.2` / `oks_map(area=1.0 proxy)`. No wire-format field or `pub`-fn renames (no silent API break). Pinned by `torso_pck_is_labelled_distinctly_from_canonical` + `pck_at_threshold_is_raw_unnormalized_not_canonical`. `wifi-densepose-sensing-server --no-default-features`: lib **450→451**, 0 failed. True unification onto `pck_canonical`/`oks_canonical` remains a tracked ADR-155 §8 item.
+- **Pre-existing `SketchBank::topk` heap inversion returned the FARTHEST sketches (found during ADR-156 §8 Pass-2 work).** The `n > k` partial-sort path in `wifi-densepose-ruvector/src/sketch.rs` used `BinaryHeap<Reverse<(dist,id)>>` (a min-heap) but its eviction logic treated the peek as the max, so it kept the k *farthest* sketches and returned them as "nearest." The shipped unit tests only exercised the `n ≤ k` fast path (≤ 3 entries), so the inversion shipped silently in ADR-084. Fixed to a plain max-heap. Pinned by `topk_heap_path_returns_nearest` (farthest-first insertion exposes it) and `tight_clusters_give_high_coverage_with_overfetch` (**measured 0.072 coverage on the old code** — effectively random — vs >0.99 fixed). Every ADR-084 top-K coverage number depends on the fixed path. MEASURED, not a no-op.
+- **ADR-154 Milestone-1 — cleared the P1 deferred backlog in `wifi-densepose-signal` (§7.4 #1, #10; partial #9, #13).** Each fix pinned by a regression test that fails on the old behaviour; every claim graded MEASURED / DATA-GATED; no fabricated thresholds. Python proof unchanged (`f8e76f21…46f7a`, bit-exact — the CIR ghost-tap guard is not on the deterministic proof path).
+  - **#1 (MEASURED metric / DATA-GATED threshold): circular phase variance.** `cir.rs::phase_variance` computed a *linear* sample variance over phase angles that wrap at ±π, so a tightly-clustered set straddling the branch cut reported spuriously HIGH dispersion — false-tripping the `> TAU` ghost-tap **guard** on real, tightly-clustered CIR taps. Replaced with Mardia's **circular variance** V = 1 − R̄, bounded **[0,1]** and invariant to where the cluster sits on the circle. The old TAU-scaled threshold is meaningless on [0,1]; re-derived against a named const `GHOST_TAP_CIRCULAR_VARIANCE_MAX = 0.99` (fires only when R̄ ≤ 0.01 — essentially uniform phase). The **metric is MEASURED**; the **threshold value is DATA-GATED** (a clean single-path ramp also sweeps the circle, so V alone can't separate clean from unsanitized without labelled frames — the default is deliberately conservative, strictly more permissive at the wrap boundary than the buggy linear guard). Fails-on-old: `phase_variance_circular_not_fooled_by_branch_cut` (old linear variance > TAU on wrap-straddling phases while circular V≈0, guard no longer trips) + `phase_variance_circular_is_bounded_and_extremal` (V∈[0,1], V≈0 identical, V≈1 uniform).
+  - **#10 (MEASURED): Welford n=0/n=1 finiteness guard pinned.** The shared `WelfordStats` (`field_model.rs`) `count < 2` guards keep `variance`/`sample_variance`/`std_dev`/`z_score` finite at the boundaries, but the n=0 case was untested (same family as the §4 divide-by-(n−1) trio). Added `welford_finite_at_n0_and_n1` — finite + documented-sentinel (0.0) at n=0/n=1. Fails-on-old proof: removing the `sample_variance` guard makes the test panic with "attempt to subtract with overflow" at the `(count − 1)` underflow (guard restored).
+  - **#9, #13 (DATA-GATED): de-magicked thresholds + boundary tests (values UNCHANGED).** Lifted the bare detection literals in `adversarial.rs` (`check`/`check_consistency`: Gini 0.8, energy ratios 2.0/0.1, consistency 0.1·mean, score weights), `coherence.rs::classify_drift` (0.85, 10) and `coherence_gate.rs` defaults (0.85/0.5/200/3.0) into named, documented consts marked EMPIRICAL DEFAULT pending labelled calibration. Added characterization/boundary tests pinning each decision at/just-below/just-above its threshold (`energy_ratio_high_boundary`, `energy_ratio_low_boundary`, `field_model_gini_boundary`, `consistency_active_fraction_boundary`, `classify_drift_*_boundary`, `*_consts_unchanged_from_literals`) so a future labelled-data retune is a visible, tested change. The operating **values were not changed**; the de-magicking + tests are MEASURED, the values stay DATA-GATED.
+- **Multistatic fusion guard was too tight for real TDM hardware (#1031).** `MultistaticConfig::default().guard_interval_us` was 5,000 µs (5 ms) with a comment claiming "well within the 50 ms TDMA cycle" — but on a real N-slot TDM schedule node `k` transmits in slot `k`, so two nodes are separated by the *slot offset*, not clock jitter. A real 2-node mesh (slots 0/1) measured an **18,194 µs** spread, so every real frame set exceeded the 5 ms guard and `fuse()` silently fell back to per-node sum/dedup — multistatic fusion never actually ran on hardware. Raised the default hard guard to **60 ms** (a full 50 ms TDMA cycle + 20% jitter headroom, derived from the slot model and documented in the field doc) and the soft guard to **20 ms** (just above the observed 18.2 ms 2-slot spread, so a normal cycle fuses cleanly with no privacy demotion). Added `MultistaticConfig::for_tdm_schedule(total_slots, slot_duration_us)` to derive the guard from a deployment's exact schedule, and a `WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US` env seam in sensing-server. The honest per-node fallback remains for genuinely-mismatched frames — now the exception, not the default. Pinned by `fuse_real_tdm_spread_18194us_fuses_with_default_guard` (fails on the old 5 ms default) + `configurable_guard_rejects_too_large_spread` (guard still rejects a spread beyond one cycle).
+- **Published HuggingFace model was unloadable — RVF format mismatch (#894).** The `ProgressiveLoader` rejected the published `ruvnet/wifi-densepose-pretrained` model with the opaque `invalid magic at offset 0: expected 0x52564653 (RVFS), got 0x77455735`, then silently fell back to signal heuristics (the "10 persons for 1" garbage reporters saw). The HF repo ships `model.safetensors`, `model-q{2,4,8}.bin` (magic `0x77455735` = "5WEw"), and `model.rvf.jsonl` — none carry the binary-RVF magic. New `model_format` module **auto-detects** RVFS / safetensors / HF-quant-bin / JSONL by magic+name, returns a **typed actionable** `ModelLoadError` (lists accepted formats + the one-command convert path — never the opaque magic), and **converts** `model.safetensors` / `model.rvf.jsonl` → RVF in-memory so the published full-precision model now loads via `--model`. A `--convert-model <in> --convert-out <out>` CLI subcommand gives a one-command offline path; the silent heuristics fallback is now a loud, actionable error. **Honest scope:** the converter wires the format/load path (safetensors F32 tensors → RVF weight segment, manifest written, Layer A/B/C all succeed, weights round-trip) — it does **not** claim end-to-end pose accuracy, since the HF pose-decoder architecture differs from this crate's inference head (still data-gated in #894). Quantized `.bin` blobs are rejected with a typed error pointing at the safetensors path. Pinned by `safetensors_converts_and_loads` + `hf_quant_classifies_to_actionable_error` (both fail on the old opaque-magic path).
+
 ### Changed
+- **ADR-157 Milestone-1 §5 #4 - native `wlanapi.dll` multi-BSSID throughput MEASURED on real hardware (`wifi-densepose-wifiscan`).** The ADR's prior status ("asserted but NOT implemented; live scanner is the ~2 Hz netsh shim") is now stale: `wlanapi_native.rs` already implements the real `WlanOpenHandle` -> `WlanEnumInterfaces` -> `WlanGetNetworkBssList` -> `WlanFreeMemory`/`WlanCloseHandle` FFI and `WlanApiScanner` already wires it native-first with a netsh fallback. This milestone **measured it on this box** (Intel Wi-Fi 7 BE201 320MHz, 2026-06-13): a new `benchmark_backend(backend, window)` drives each backend over the same fixed 10 s wall-clock window so netsh is timed independently (the prior `benchmark()` picked native-first and never measured netsh on a Windows box where native works). **MEASURED: native 21.42 Hz vs netsh 3.84 Hz = 5.57x** (mean 5.0 BSSIDs/scan, both paths); a separate native-only run measured 18.0 Hz. Native genuinely beats netsh - this is a real positive result, not a fabricated "10x". 50 back-to-back native scans completed 50/50 with no handle leak/degradation. Live-WLAN tests (`measure_native_vs_netsh_throughput`, `native_scans_dont_leak_handles`, `measure_native_scan_rate`) are `#[ignore]` for CI but were RUN here; `native_scan_runs_real_ffi_on_windows` is a non-ignored schema-valid pin. ADR-157 §5 #4 + §8 -> MEASURED (was ACCEPTED-FUTURE / CLAIMED-unmeasured).
 - **Mesh partition risk now demotes the privacy class and is witnessed (ADR-032).** The dynamic min-cut guard's `at_risk` signal was advisory-only (it fed the recalibration advisor). It now also contributes to the ADR-141 privacy demotion alongside fusion- and array-level contradictions: a mesh close to partitioning makes the fused belief less trustworthy, so the cycle emits at a more restricted class (monotonic — information only removed). Because `effective_class` feeds the BLAKE3 witness, a fragmenting array now shifts the witness — partition risk is auditable, not just logged. The mesh computation moved ahead of the demotion step in `process_cycle`; new `mesh_guard_mut()` exposes risk-threshold tuning. Test proves a forced-risk 3-node cycle demotes PrivateHome Anonymous→Restricted and shifts the witness vs a clean *same-topology* baseline (the only delta between the two cycles is the forced risk).
 
 ### Added
+- **ADR-154 Milestone-2 — bench-first P2 perf subset + missing boundary tests (`wifi-densepose-signal`, §7.4 #5/#6/#7/#8/#14/#16/#19/#20).** PROOF discipline (ADR-154 §0): every perf item was **benched before being touched** (new committed `benches/dsp_perf_bench.rs`, criterion, this Windows box); only the one item the bench proved hot was optimized, the rest are committed MEASURED-NULLs — a benched null is the proof the micro-opt was unnecessary, the §5.1 "already amortized" pattern. Every behaviour-changing edit is pinned bit-identical (or documented-tolerance). Signal crate lib `--no-default-features`: **447 passed, 0 failed, 1 ignored**; `--features cir`: **447 passed, 0 failed**.
+  - **#20 MEASURED-HOT, optimized (bit-identical).** `compute_multi_subcarrier_spectrogram` re-planned a fresh `FftPlanner` for *every* subcarrier (via `compute_spectrogram`). Hoisted the plan + window out of the per-subcarrier loop (new `compute_spectrogram_with_plan` core; `compute_spectrogram` delegates, unchanged). **56-subcarrier: 467.88 µs → 254.75 µs = 1.84×** (window 128); **627.27 µs → 448.39 µs = 1.40×** (window 256). Bit-identical via `multi_subcarrier_hoisted_plan_bit_identical` (`f64::to_bits` of every value across all 4 window functions × {power,magnitude}). The §7.4 intro's predicted "most likely real win" — confirmed.
+  - **#5 / #6 / #7 MEASURED-NULL, left as-is.** `node_attention_weights` 181 ns (2 nodes)…848 ns (8) — sub-µs, no hot-path alloc. `tomography reconstruct` (full 50-iter ISTA, 256 voxels) 47.5 µs (16 links) / 60.4 µs (32) — the 2 voxel buffers are already alloc-once + `.fill`-reused, negligible vs O(iters·links·voxels). `pose_tracker` Kalman cycle 150 ns (17 keypoints) / 2.82 µs (170) — the "gain matrices" are fixed-size **stack** arrays, zero heap to reuse. No rewrite shipped; the committed benches prove each is not hot.
+  - **#8 MEASUREMENT-ONLY, BLAS-gated (number deferred, not fabricated).** Correction to the finding: `extract_perturbation` does **not** recompute the SVD (it projects against cached `finalize_calibration` modes); the real per-call eigendecomposition is the `eigenvalue`-feature `estimate_occupancy` (`cov.eigh()` on a 56×56 covariance). The `eig` bench is committed but `openblas-src` won't build on this Windows host ("Non-vcpkg builds are not supported on Windows" — the exact reason the project gate runs `--no-default-features`), so its µs cost must come from a Linux/BLAS box. Recorded, not estimated. Incremental SVD stays a sized future item.
+  - **#14 / #16 / #19 RESOLVED — tests added (no behaviour change).** `fft_operator_within_tolerance_of_dense_canonical56` pins the full `Cir` output of the opt-in FFT path within a documented relative tolerance of the dense path on the production canonical-56 config (τ ∈ {20,50,90} ns) — it changes the witness hash, so it must be provably *close*, not silently divergent. `refinement_terminates_at_iteration_cap_when_not_converging` (+ convergent companion) proves the LO-offset refinement terminates at exactly `max_iterations` on a non-converging input (cap, not convergence, bounds the loop; internal `…_counted` refactor returns the identical offsets). `ratio_finite_at_and_below_1e_12_epsilon` pins that the conjugate-product CSI-ratio (no division → no `1e-12` divide-guard needed) is finite + bit-exact at/below the epsilon boundary and at exact zero (where a naive `H_i/H_j` ratio is ±inf/NaN).
+- **ADR-156 §11 Milestone-2: RaBitQ unbiased distance estimator — IMPLEMENTED & MEASURED (RESOLVED-NEGATIVE on the strict-K bar).** Closes the §10.5 / §8 backlog "full RaBitQ residual-distance estimator (not just a uniform scalar code)" item — the **real** Gao & Long (SIGMOD 2024) contribution, not just sign bits. New `wifi-densepose-ruvector/src/estimator.rs`: `EstimatorSketch` carries the Pass-2 sign code (over the padded FHT length `D = next_pow2(dim)`) **plus 8 B/vec side info** (`residual_norm` + `x_dot_o = ⟨x̄, o'⟩`, 2× f32); `DistanceEstimator` computes the **unbiased** estimate `⟨o',q'⟩ ≈ ⟨x̄,q'⟩ / x_dot_o` (the random rotation makes the 1-bit code's quantization error orthogonal-in-expectation to the query, paper `O(1/√D)` bound); `EstimatorBank::topk_estimated_cosine` reranks the candidate set by the estimate instead of raw Hamming. **Zero-centroid simplification (`c = 0`) stated honestly** — the paper-faithful per-cluster centroid path (`from_embedding_centred` / `EstimatorBank::with_centroid`) is also built so the simplification is a measured choice (no centroid coverage number is reported against the cosine ground truth, because cosine-of-residual ≠ cosine-of-raw would be a metric mismatch). **Purely additive + backward-compatible** — new types only; Pass-1 `Sketch` / Pass-2 `SketchBank` / `WireSketch` wire format unchanged; all external callers (`event_log.rs`, `signal/longitudinal.rs`, `sensing-server`) use Pass-1 and are unaffected. **MEASURED strict-K coverage** (same fixture/seeds as §10: dim=128 N=2048 K=8, 64 clusters, noise=0.35, 128 queries, cosine ground truth): the estimator lifts the strict `candidate_k=K` bar **46.39% (Pass-2 sign) → 49.71% (estimator, cosine rerank)** — a real **+3.3 pp** lift, **still ~40 pp short of the ADR-084 ≥90% strict bar.** At over-fetch the estimator beats sign (candidate_k=24: **95.12%** vs 91.60%). **Honest verdict — RESOLVED-NEGATIVE: the unbiased estimator does NOT clear the strict-K 90% bar on this distribution** (the binding constraint is the 1-bit code's information ceiling, not estimator variance); the bar is still met only via the over-fetch "candidate set" pattern ADR-084 specifies, though the estimator **reduces the over-fetch factor** needed. A published negative, reported as such — no benchmark tuned to manufacture a pass. Unbiasedness pinned by `estimator_unbiased_on_fixture` (Monte-Carlo mean over 4000 rotation seeds → true inner product within tolerance); not-worse-than-sign pinned by `estimator_rerank_not_worse_than_sign`; determinism by `estimator_is_deterministic`. +12 tests in the crate (119→131). Workspace **3,228 / 0 failed** (`cargo test --workspace --no-default-features`, 162 test binaries, single clean run), Python proof **VERDICT: PASS** (`f8e76f21…46f7a`, unchanged — estimator is not on the proof's signal path). Full numbers + reproduce commands in ADR-156 §11 / ADR-084 "Pass 2b".
+- **ADR-156 §8 Milestone-1: RaBitQ Pass-2 randomized rotation + multi-bit experiment — IMPLEMENTED & MEASURED (RESOLVED-PARTIAL).** Closes the §8 "Multi-bit / Extended RaBitQ" backlog item. New `wifi-densepose-ruvector/src/rotation.rs`: a deterministic randomized orthogonal rotation `R = H·D` — **Fast Hadamard Transform** (`O(d log d)`, in-place, `1/√m`-normalized so norm-preserving) + seeded ±1 sign flips (SplitMix64 from a stored `u64` seed; identical at index + query time). Chosen over a dense `d×d` matrix (`O(d²)`, infeasible at the 65,535-d the wire format provisions for); pads to `next_pow2(d)`. Additive, backward-compatible API (`Sketch::from_embedding_rotated`, `SketchBank::with_rotation` + `insert_embedding`/`topk_embedding`/`novelty_embedding`); Pass-1 and the wire format are byte-for-byte unchanged. New `coverage.rs` single-source-of-truth top-K coverage harness (anisotropic planted-cluster fixture, cosine ground truth) backs both a `#[test]` report and the `sketch_bench` coverage table. **MEASURED (dim=128 N=2048 K=8, 64 clusters, noise=0.35, 128 queries, seeded):** at the strict `candidate_k=K` bar, rotation lifts coverage **36.13% → 46.39%**; Pass-2 reaches the **ADR-084 ≥90% bar at candidate_k=24 (~3× over-fetch)**; multi-bit Pass-3 reaches 54%/67%/74% at 2/3/4-bit (strict bar). **Honest verdict: neither rotation nor ≤4-bit multi-bit clears the strict-K 90% bar on this distribution — the bar is met only via the over-fetch "candidate set" pattern ADR-084 specifies.** No benchmark was tuned to manufacture a pass; the strict-bar gap is documented (ADR-156 §10, ADR-084 "Pass 2" section). +19 tests in the crate (100→119), workspace **3,225 / 0 failed**, Python proof VERDICT: PASS (`f8e76f21…`, unchanged — sketch is not on the proof's signal path).
+- **Beyond-SOTA `v2/crates/` sweep (ADR-154–158) + full stub-implementation push — every claim MEASURED or graded.** A 5-milestone review/optimize/secure/benchmark/validate sweep, then a verified-audit-driven push to replace every production stub with real, tested logic (no labels, no placeholders). Each fix is pinned by a test that fails on the old code; every number ships with a reproduce command.

SOTA graded: SymphonyQG (CLAIMED), multi-bit RaBitQ (near-term), GraphPose-Fi (data-gated).

After repairing both, retraining with upstream defaults on an RTX 5080 reproduced **96.09% PCK@20 (full test) / 96.61% (corruption-free)** — claims graded MEASURED-EQUIVALENT; params (2,225,042) and FLOPs (~0.055 G) verified exactly.

 - **Dynamic min-cut mesh partition guard in the streaming engine (`mesh_guard`).** Maintains a `ruvector-mincut` exact min-cut over the live mesh coupling graph (nodes = sensing nodes, coupling = product of fusion attention weights), surfacing per cycle: the global **cut value** (how close the array is to splitting — a structural measure per-node heuristics miss), the **weak side** (which specific nodes would partition: failure/jamming triage feeding ADR-032 posture), and an **at-risk flag** that counts as a structural event for the drift→recalibration advisor. Surfaced as `TrustedOutput::mesh`. **Measured cost policy** (criterion, 12-node mesh): weights are quantized (1/64; a *nonzero* coupling below one quantum saturates to quantum 1 so quantization never erases a live coupling — without the floor, balanced meshes of ≥ 65 nodes had every ~1/n coupling erased and sat permanently "at risk") and updates change-gated, so the steady-state cycle does zero graph work (~7.3 µs, ~23× cheaper than building); on any real change a full exact rebuild (~171 µs) is used because one `DynamicMinCut` delete+insert measured ~240 µs — the incremental machinery's overhead targets much larger graphs, so rebuild-on-change is the measured optimum at mesh scale (one-edge case −28% after the policy switch). Degenerate cases fail toward risk: a node with zero coupling is reported as already partitioned (cut 0). 9 mesh-guard tests + an engine-level wiring test; full `process_cycle` with the guard: ~33 µs for 4 nodes (50 ms budget).
 - **Opt-in FFT operator for the CIR ISTA solver (8–14× measured).** Φ is a sub-DFT, so each ISTA mat-vec can run as one length-G FFT (O(G log G)) instead of a dense O(K·G) product. New `CirConfig::fft_operator` (default **false** — the dense path stays the bit-exact witness default; the FFT evaluates the same sums in a different order, so enabling it shifts float results and requires regenerating any pinned witness). `FftOperator` (rustfft, planned once at construction, scratch reused across the ISTA loop) dispatches inside `ista_solve`; warm-start/Lipschitz stay dense at construction. Measured (criterion, same run): ht20 2.22 ms → 265 µs (**8.4×**), ht40 10.26 ms → 717 µs (**14.3×**); the real HE40 grid (K=484, G=1452) scales further. 3 new tests: FFT↔dense matvec equivalence to float tolerance (ht20 + he40 grids), end-to-end dominant-tap agreement on a single-path frame, and all default configs keep FFT off. New `cir_estimate_fft` bench group.
 - **Per-room adapter provenance + drift→recalibration advisor in the streaming engine.** Closes the trust-chain gap where an ~11 KB per-room LoRA adapter (ADR-150 §3.4) could silently change inference without the witness noticing. `StreamingEngine::set_room_adapter(AdapterInfo)` pins the adapter's content-derived id into provenance `model_version` (`rfenc-v1+adapter:<id>`) — and therefore into the BLAKE3 witness — so swapping or clearing adapter weights always shifts the witness (engine test proves base → adapter → other-adapter → cleared all witness differently, and cleared == base). New `RecalibrationAdvisor` recommends re-running the ADR-135 baseline / refitting the adapter on sustained low fusion coherence (streak threshold, default 60 cycles ≈ 3 s at 20 Hz) or an ADR-142 change-point; surfaced as `TrustedOutput::recalibration_recommended` and recorded on the sensing-server's `EngineBridge` alongside the witness. Bridge plumbing: `EngineBridge::{set_room_adapter, clear_room_adapter}` + live-path test that the adapter id flows into the live witness. *Scope note: this is the deployable provenance/trigger half of the "retrained model" roadmap item — fitting the adapter itself runs in the existing external calibration service (`aether-arena/calibration/`), and a trained RF-encoder checkpoint still does not exist in-tree.*

Bit-identical floats (summation order unchanged, witness chain unaffected). Measured: `cir_estimate/he40` −3.9% (p<0.01), multiband groups −1.2/−1.4%; smaller configs within container noise.

 - **Live trust path: sensing-server routes real frames through the governed `StreamingEngine` (parallel governed path with partial output gating).** Previously the live server ran only the *bare* `MultistaticFuser` (fused amplitudes, no trust control plane), while the privacy/provenance/witness engine (ADR-135..146) ran only on synthetic in-test frames — the gap called out in ADR-136 §8 and the beyond-SOTA system review. New `engine_bridge` module drives `StreamingEngine::process_cycle` from the server's live `NodeState` map (reusing the existing `NodeState → MultiBandCsiFrame` conversion), lazily wiring each node as a WorldGraph sensor and bounding belief growth via the retention cap; every *governed belief* carries evidence + model + calibration + privacy decision and a deterministic witness. **Honest scope:** the engine runs alongside (not instead of) the bare fusion path that feeds the live `SensingUpdate`. What its decision gates on the wire today: a cycle emitted at class `Restricted` (base mode or contradiction/mesh-risk demotion) suppresses the per-node raw amplitude vectors from the live publish — the same field mapping `wifi-densepose-bfld`'s privacy gate applies at `Restricted`; gating the remaining derived outputs (person count, classification, signal field) is tracked as a follow-up. Trust state is no longer write-only: the latest witness, effective privacy class, demotion flag, recalibration recommendation, and an engine-error counter are readable on `GET /api/v1/status`, and engine errors are counted + rate-limit logged instead of silently swallowed (`EngineBridge::observe_cycle`). Adds `wifi-densepose-engine/-worldgraph/-bfld/-geo` deps. Bridge tests cover witnessed belief with provenance, determinism, idempotent node registration, retention bound, privacy-mode propagation, trust-state recording, the error-counter path, and Restricted-class raw-output suppression.
 
 ### Fixed
+- **Real HE20 CSI no longer silently dropped or replaced with simulated data (fixes #1009, #1004).** Two ingest bugs caused real ESP32-C6 HE20 frames to be discarded or never received — the exact "real data silently lost" failure class the project fights. Each fix is pinned by a test that fails on the old code.
+  - **#1009 §1b — HE20 baseline recorder trimmed 256 → 242 bins by sequential index (`wifi-densepose-signal/src/ruvsense/calibration.rs`).** ESP-IDF v5.5.2 delivers all 256 FFT bins for an HE20 frame; `CalibrationConfig::he20()` carried `num_active: 242`, so the recorder (which has no HE20 tone map — `extract_first_stream` takes the first `num_active` columns *sequentially*) kept bins 0..242 of the 256-bin grid. Those are the lower guard band + DC, **not** the 242 active tones, silently corrupting the empty-room baseline. Now `num_active: 256` records every delivered bin, staying aligned 1:1 with the live `deviation()` path. The exact-242 tone map deliberately stays only in `cir.rs` (`HE20_ACTIVE`), where the Φ sensing matrix genuinely needs it. Test `he20_records_all_256_bins_not_trimmed_to_242` asserts the finalized baseline covers all 256 bins (was 242). HE20 synthetic/bench fixtures updated to feed 256-bin frames (the real wire format).
+  - **#1009 §1a/§1c — already-fixed u8→u16 `n_subcarriers` truncation, now regression-pinned.** The ADR-018 wire format carries `n_subcarriers` as u16 LE at bytes 6–7. A 256-bin HE20 frame (byte6=0x00, byte7=0x01) read as a single byte decodes to **0 subcarriers** → every frame skipped (invisible until HE20: ESP32-S3's ≤192 bins fit in one byte). The CLI parser (`wifi-densepose-cli/calibrate.rs`) and the sensing-server template parser (`wifi-densepose-sensing-server` `parse_esp32_frame`) were already corrected to u16 under #1005/ADR-110; added regression tests (`parse_esp32_frame_he20_256_bins_not_truncated`, CLI `test_parse_csi_packet_he_su_256_bins`) that fail on the old single-byte read so the truncation cannot silently return.
+  - **#1004 — `--source auto` latched on `simulate` forever, never binding UDP :5005 (`wifi-densepose-sensing-server/src/main.rs`).** A one-shot boot probe resolved the source once; with no CSI flowing at boot (the normal firmware/server startup race) it served simulated poses for the whole process and ignored real CSI that arrived seconds later (the prior #937 fix hard-exited instead — equally wrong, the server could never pick up late-starting CSI). New `plan_source()` state machine: in `auto` mode **always bind the UDP receiver** and serve simulated data only until the first real frame, at which point `udp_receiver_task` promotes `source` → `esp32` (mirroring the existing `esp32 → esp32:offline` reversion in `effective_source()`); `simulated_data_task` self-suspends once promoted so it never clobbers live CSI. Explicit `--source simulated` stays a hard, UDP-free override for offline demos. 6 unit tests pin the resolution/promotion machine (`auto_with_no_boot_source_still_binds_udp_and_simulates`, etc.); the auto-binds-UDP assertion fails on the old behavior.
 - **`wifi-densepose-mat` standalone `--no-default-features` build (101 errors → 0).** `pub mod api` was unconditional while its only dependency, serde, is optional behind the `api` feature — so any build without default features failed with unresolved serde imports (masked in `--workspace` runs by feature unification). The `api` module and its `create_router`/`AppState` re-export are now `#[cfg(feature = "api")]`-gated (with docsrs annotations). All feature combos compile: bare `--no-default-features`, `--no-default-features --features api`, and full default (177 tests pass).
 - **WorldGraph no longer grows unboundedly under the live loop.** `StreamingEngine::process_cycle` appended one `SemanticState` belief per cycle with no eviction — ~1.7M nodes/day at 20 Hz (identified in `docs/research/ruview-beyond-sota/04-optimization-roadmap.md`). Added `WorldGraph::prune_semantic_states(max)` — deterministic eviction of the oldest beliefs by `(valid_from_unix_ms, id)`, structural nodes (rooms/zones/sensors/anchors/tracks/events) never eligible — and wired it into the engine after each belief append (`StreamingEngine::DEFAULT_SEMANTIC_RETENTION` = 7,200 ≈ 6 min at 20 Hz; tunable via `set_semantic_retention`). The WorldGraph holds *current* beliefs; durable history is the recorder's job, so no audit data is lost. 3 new tests (bounded growth end-to-end, oldest-only eviction, deterministic tie-break).
 - **ESP32 edge heart rate no longer stuck at ~45 BPM / dropping wildly — #987.** The on-device HR estimator (`edge_processing.c`, `0xC5110002`) reported ~45 BPM regardless of true heart rate (Apple-Watch ground truth 87 BPM read as ~45) and swung frame-to-frame. Two root causes: (1) a hardcoded `sample_rate = 10.0f` that became wrong after #985's self-ping raised the CSI callback rate to a variable ~13–19 Hz — BPM scales as `assumed/actual × true`, so 87 read ~45 and the reading swung as CSI yield fluctuated; (2) the zero-crossing estimator locked onto a breathing harmonic (a 0.25 Hz breathing fundamental puts its 3rd harmonic at ~0.74 Hz ≈ 44 BPM inside the HR band). Fix: measure the real sample rate from inter-frame timestamps (used for BPM conversion + biquad re-tuning on >15% drift); replace the HR zero-crossing with an autocorrelation estimator that rejects breathing harmonics (driven by a robust autocorr breathing period); median-13 smooth the output. Hardware A/B (fixed vs unmodified control board, both `edge_tier=2`): control pegged 40–49 BPM; fixed reaches the true 88–91 BPM (vs 87 GT) and holds a stable physiological value (spread 59→0 for a steady subject). Known limitation: heavy subject motion still degrades the estimate (motion gating is a follow-up).

 - **ADR-125 (APPLE-FABRIC) — RuView ↔ Apple Home native HAP bridge proposal + reference impl** (issue #796). New ADR-125 lays out a three-phase plan to expose RuView as a discoverable HomeKit accessory on the LAN so a HomePod (as Home Hub) sees presence / vitals / BFLD-derived events natively — zero Home-Assistant intermediary. Two architectural decisions resolved in the ADR per design review: (1) **one HAP bridge with N child accessories** (single pairing, matches Hue/Eve pattern), and (2) **identity-risk mapping is semantic, not probabilistic** — `identity_risk_score` and Soul-Signature match probability never cross the HAP boundary; instead three thresholded events are exposed (`Unknown Presence`, `Unexpected Occupancy`, `Unrecognized Activity Pattern`) so RuView reads as calm-tech ambient awareness, not surveillance UX. ADR-125 §2.1.a reference impl ships now: `scripts/hap-test-sensor.py` (HAP-1.1 bridge advertised over mDNS, paired with operator's iPhone) + `scripts/c6-presence-watcher.py` (parses ESP32 `RV_FEATURE_STATE_MAGIC = 0xC5110006` UDP packets with IEEE CRC32 validation, hysteresis, and a Python port of `wifi-densepose-bfld::PrivacyClass` that enforces ADR-125 §2.1.d invariant I1 at the HomeKit edge — only `Anonymous` (2) and `Restricted` (3) frames may cross; `Raw`/`Derived` are refused with exit code 2 and the cited ADR clause). Validated end-to-end on real hardware (no mocks): ESP32-C6 on `ruv.net` → UDP/5005 → mac-mini watcher → BFLD gate → HAP bridge → iPhone Home app shows `Unknown Presence` live characteristic flip. **Empirical**: 50-51 valid CRC-passing feature_state packets per 10 s window from the live C6; zero CRC errors.

+"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.
+

+# 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.
+
+---
+
+## Status vs the deferred items
+
+| Deferred item | Was | Now |
+|---|---|---|
+| ADR-160 "Criterion benches for `process_frame` budget claims" | ACCEPTED-FUTURE | **DONE (host)**; ESP32-on-hardware still **PENDING** (needs the wasm32 target + a flashed ESP32-S3) |
+| ADR-159/160 cog inference latency (`cold_start_ms_avg` uncommitted-benched) | CLAIMED | **MEASURED-on-host (steady-state)**; cold-start-on-ruvultra remains the manifest's separate claim |
+
+Nothing here changes runtime behavior — these are benches + this results file
+only. No crate needs republishing.

+
+### 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_seizure_detect` | "seizure-like" motion is not a seizure; no ground-truth signature exists synthetically | Clinical EEG-/video-labelled tonic-clonic seizure CSI from instrumented patients |
+| `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 |
+| `exo_gesture_language` | coarse gesture clusters ≠ true sign language (ADR-160 §A4) | Labelled ASL letter/word CSI dataset |
+
+> The above are **not failures** — they are the honest boundary. A smaller set of
+> genuinely-measured skills plus this explicit gated list is the deliverable, per

+## Security P0 closure note (2026-06-13) — Rust sensing-server boundary
+
+The three P0 security findings below were logged against the **Python v1** API
+(`archive/v1/src/…`). ADR-164 G11 re-scoped them to the *shipped* boundary:
+`wifi-densepose-sensing-server` (Rust). They were verified against the current
+Rust crate and closed on branch `fix/adr-080-sensing-server-security`. Each fix
+(or already-fixed finding) is pinned by a test that fails on the old behavior.
+**The Python v1 paths remain as-is** — v1 is archived and not the shipped
+surface; this closure governs the live Rust server only.

+- **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.

+
+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

+
+## 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).

+
+---
+
+## 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 remain deferred. 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).
+
+| # | 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 here** (branch removed, sequential-convention documented to match the sibling `extract_first_stream`). Listed for visibility — behavior 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. |

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. |

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 | Cosmetic. |
+| 18 | motion.rs | Threshold constants undocumented | P3 | Doc-only. |
+| 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 | Bulk-addressable in a dedicated "test-the-boundaries + de-magic-constant" follow-up; not high-leverage individually. |

+
+## 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).
+- **`rf_encoder.rs` `assert_eq!`-on-checkpoint** and any other **tch-gated** panic-on-input sites — 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) from the NN/training gap review.
+
+### 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)
+
+| Field | Value |

+| **Date** | 2026-06-11 |
+| **Deciders** | ruv |
+| **Codebase target** | `wifi-densepose-ruvector` — `viewpoint/` (`attention.rs`, `geometry.rs`, `fusion.rs`, `coherence.rs`), `mat/` (`triangulation.rs`, `heartbeat.rs`), `sketch.rs`, benches, docs |

+---
+
+## 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.
+

+| **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. | **CLAIMED** (author-measured; **not reproduced on our hardware** — reproduction is future work) | **Lead beyond-SOTA candidate for the ruvector ANN path.** Propose as ACCEPTED-future; cite honestly as "claimed by source, reproduction pending." Best fit because the ruvector retrieval path (AETHER re-ID, sketch prefilter) is exactly an ANN problem and SymphonyQG is CPU/edge-portable like our deployment. |
+| **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) — reproduce the 3.5–17× QPS-over-HNSW claim on our hardware before integrating into the ruvector ANN path. Currently CLAIMED-only.
+- **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 |
+|---|---|---|---|---|---|
+| **8 (= K, strict bar)** | 36.13% | 46.39% | **49.71%** | 49.02% | **all BELOW** |
+| 16 | 62.79% | 75.59% | 79.20% | 77.93% | below |
+| 24 | 83.89% | 91.60% | **95.12%** | 93.65% | estimator clears |
+| 32 | 100.00% | 100.00% | 100.00% | 100.00% | clears |
+| 64 | 100.00% | 100.00% | 100.00% | 100.00% | clears |
+
+Side-info memory overhead: **8 bytes/vector** (2× f32) on top of the 16 B/vec 1-bit sketch.
+
+### 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`.

+# ADR-157: Hardware / Sensing-Acquisition Layer Beyond-SOTA Sweep — Milestone 3 (An Already-Hardened Layer, Three Small Real Fixes, an Honestly-Null Perf Win, and a Mostly-NO-ACTION SOTA Landscape)
+
+| Field | Value |

+| **Status** | Proposed |
+| **Date** | 2026-06-11 |
+| **Deciders** | ruv |
+| **Codebase target** | `wifi-densepose-vitals` (`heartrate.rs`, `breathing.rs`, `anomaly.rs`, `store.rs`), `wifi-densepose-wifiscan` (`pipeline/breathing_extractor.rs`, `pipeline/correlator.rs`, `adapter/netsh_scanner.rs`), `wifi-densepose-hardware` (`esp32_parser.rs`, `sync_packet.rs`, `esp32/secure_tdm.rs`, `ieee80211bf/*`), `wifi-densepose-calibration` (`geometry_embedding.rs`), benches, docs |

+| **Scope** | Milestone 3 of the beyond-SOTA sweep across the four hardware/sensing-acquisition crates. The honest headline: **this layer is already well-hardened** — the real work is small. Three correctness/stability fixes (each pinned by a test that fails on the old code), one algorithmic perf change whose end-to-end win is **null at realistic window sizes** (disclosed, not inflated) with a committed bench, one defense-in-depth hardening on an unreachable path, a **MEASURED negative-results section** (the centerpiece — what was investigated and found already-correct), a graded SOTA landscape that is **mostly NO-ACTION**, and a deferred backlog. **Nothing is silently dropped.** |
+
+---
+
+## 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.
+
+## Graded SOTA Landscape
+
+| Capability | Grade | Note |
+|------------|-------|------|
+| 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)
+cargo test -p wifi-densepose-worldmodel   # 12 + 1
+cargo test -p wifi-densepose-worldgraph   # 9
+cargo test -p wifi-densepose-geo          # 9 + 8
+cargo test -p wifi-densepose-engine       # 27
+```
+
+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.

+# ADR-160: Edge Skill Library (`wifi-densepose-wasm-edge`) — Honest Labeling & Soundness Cleanup

+
+## 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 --features std,medical-experimental     # med_* skills enabled
+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-159's deferred-backlog statement *"wasm-edge … honestly labelled, not
+  claimed"* is now actually TRUE.

+# ADR-161: HOMECORE Server Layer — WebSocket Auth Bypass, Reply-Theater & Documented-but-No-Op Automation (Security & Honest Labeling)
+
+- **Status**: accepted
+- **Date**: 2026-06-12
+- **Deciders**: ruv
+- **Tags**: homecore, http-ws-boundary, websocket-auth-bypass, security, automation-engine, documented-no-op, prove-everything, soundness, honest-labeling
+- **Amends**: ADR-130 (HOMECORE-API WS protocol), ADR-129 (HOMECORE-AUTO automation engine), ADR-128 (plugin manifest)
+
+## 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**.
+
+Grading vocabulary (ADR-152 / ADR-158 / ADR-160):
+- **MEASURED** — reproduced in this worktree, command + failing-on-old test recorded.
+- **NO-ACTION (already-honest/already-hardened)** — audited, found correct, cited as a positive.
+- **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`).

+# 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 |
+
+## Remaining honest deferral (Nothing Dropped)
+
+- **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
+  hash, so P4/P5 apply only to the WASM (`wasmtime`) path; native plugins remain
+  trusted-by-compilation. Honestly noted, not over-claimed.
+- **HAP real pairing (P2)** — unchanged from ADR-161; out of M8 scope.
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2
+# P4/P5 (wasmtime feature needs rustc 1.91+; workspace pins 1.89 for the rest):
+cargo +1.91.1 test -p homecore-plugins --features wasmtime
+# Bounded RunModes:
+cargo test -p homecore-automation --no-default-features
+# Full workspace still builds (1.89 toolchain, no wasmtime):
+cargo build --workspace --no-default-features
+```
+
+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
+  (`engine.rs` 433, `runmode.rs` 153, `verify.rs` 397, `permissions.rs` 168;
+  `wasmtime_runtime.rs` non-test source < 500, inline WAT tests as ADR-161 left
+  them).

+# 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.

+
+---
+
+## 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`).
+
+### 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)
+
+- 19 tests (`cargo test -p homecore-migrate`), per the crate README badge.
+
+## 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.

+
+## 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,

+  },
+  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: {

+  },
+  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 },

+    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.

+# ADR Corpus Gap Analysis — Five-Lens Findings
+
+Research notes backing ADR-164. Each lens output is reproduced verbatim. Census: 162 ADR entries across 156 distinct files (6 duplicate-number collisions verified on disk).
+
+---
+
+## Lens 1: status-distribution
+
+Confirmed: ADR-168-benchmark-proof.md (was ADR-147-benchmark-proof.md) and ADR-134-csi-to-cir have no `Status` line in their headers (the 167-ddd hits are Rust code in the body, not a header; the ADR-167 appendix, was ADR-052-ddd, lacks a real Status header per its first lines). Findings are evidence-grounded. Final analysis below.
+
+### ADR Corpus — Status & Implementation Distribution
+
+Census: **162 ADR entries** across **156 distinct files** (6 duplicate-number collisions verified on disk).
+
+#### Status tally
+
+| Status bucket | Count |
+|---|---|
+| Accepted (incl. "Accepted — partial/in-progress/Phase 1" variants) | ~56 |
+| Proposed (incl. "Proposed — conditional/research-only") | ~88 |
+| Superseded | 1 (ADR-002) |
+| Rejected | 1 (ADR-098) |
+| Missing / no Status header | 3 (ADR-168-benchmark-proof [was 147], ADR-167-ddd appendix [was 052], ADR-134-CIR) |
+| Mixed/dual status in one ADR | 3 (ADR-115, ADR-149-AetherArena vs swarm, ADR-133) |
+
+#### impl_state tally
+
+| impl_state | Count |
+|---|---|
+| implemented | ~36 |
+| partial | ~50 |
+| proposed-only | ~64 |
+| stale-or-contradicted | 3 (ADR-029, 030, 031) |
+| unknown | 5 (ADR-034, 044, 167-ddd [was 052], 168-proof [was 147], …) |
+| 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** — Accepted/implemented work still labeled "Proposed."
+
+#### SEVERITY: CRITICAL — Status header missing or structurally absent (cannot triage)
+
+- **ADR-168-benchmark-proof.md** (renumbered from ADR-147 to resolve the 147 collision) — *No `Status` header at all* (grep confirmed). Not a true ADR; it's a benchmark artifact (OccWorld @ ~213ms on RTX 5080, random weights) that was misfiled under the ADR-147 number. **Action: relocate to `docs/proof/` or `benchmarks/`, remove ADR number.**
+- **ADR-134-csi-to-cir-time-domain-multipath.md** — *No `Status` header* (grep confirmed) in the header region. Body says Proposed but the field is not in canonical position. Compounded by a **number collision**: ADR-126/129 reference "ADR-134" as HOMECORE-MIGRATE, but the on-disk file is CIR. **Action: add canonical `## Status` line; resolve the 134 identity split.**
+- **ADR-167-ddd-bounded-contexts.md** (renumbered from ADR-052 to resolve the 052 collision; still an appendix to parent ADR-052) — Appendix doc with no Status/Date header (grep found only Rust code, no header field). **Action: mark explicitly "Appendix to ADR-052 (no independent status)".**
+
+#### SEVERITY: CRITICAL — Duplicate ADR numbers (6 collisions, all verified on disk)
+
+| Number | Colliding files | Action | Resolution |
+|---|---|---|---|
+| **147** | adam-mode-light-theme · nvidia-cosmos/OccWorld · benchmark-proof | Renumber 2 of 3 | **RESOLVED** — 147 keeps nvidia-cosmos/OccWorld; benchmark-proof → **ADR-168**, adam-mode → **ADR-169** |
+| **148** | drone-swarm-control-system · yoga-mode-pose-system | Renumber 1 | **RESOLVED** — 148 keeps drone-swarm; yoga-mode → **ADR-170** |
+| **149** | AetherArena-leaderboard · swarm-benchmarking | Renumber 1 | **RESOLVED** — 149 keeps AetherArena; swarm-benchmarking → **ADR-171** |
+| **050** | provisioning-tool-enhancements · quality-engineering-security-hardening | Renumber 1 | **RESOLVED** — 050 keeps provisioning (5 refs vs 1); quality-engineering → **ADR-166** |
+| **052** | tauri-desktop-frontend · ddd-bounded-contexts (appendix) | Demote appendix | **RESOLVED** — 052 keeps tauri; ddd appendix renumbered → **ADR-167** (still linked to parent 052) |
+| **134** | csi-to-cir (on disk) · HOMECORE-MIGRATE (referenced, no file) | Resolve identity | Identity split (not a filename collision); resolved separately via G3 → ADR-165 |
+
+These broke the ADR index and `/adr` tooling — two ADRs answering to one number is a corpus-integrity defect, not cosmetics. The five filename collisions are now resolved (six displaced files renumbered 166–171); see ADR-164 Gap Register G1.
+
+#### SEVERITY: HIGH — Status header stale vs. shipped reality (Proposed header on landed code)
+
+These are the most dangerous: an auditor reading the header concludes "not built" when code + tests exist. Ranked by blast radius:
+
+1. **ADR-136 → ADR-145** (streaming-engine series, 10 ADRs) — every header says `Proposed` but each `§ Implementation Status` reports **"Built" with pinned commits + passing tests** (136: 11f89727f; 137: 4fa3847ac; 138: fc7674bde; 139: 521a012d8; 140: 169a355bd; 141: 7d88eb84c; 142: 1f8e180d6; 143: 2d4f3dea5; 144: b10bc2e9a; 145 referenced as landed by 149/150/151). **Bulk action: flip headers to "Accepted — partial (integration glue pending)".**
+2. **ADR-029 / 030 / 031** (RuvSense/field-model/cross-viewpoint) — `Proposed` but repo has `signal/src/ruvsense/` (16 modules) and `ruvector/src/viewpoint/`, and **Accepted ADR-032 hardens them** — an Accepted ADR depending on Proposed parents (status-graph inversion).
+3. **ADR-095 / 096** (rvCSI) — `Proposed` but ADR-097 confirms built, extracted to own repo, published 0.3.1 to crates.io/npm.
+4. **ADR-152** — `Proposed` but CLAUDE.md + recent commits report §2.1–2.3/2.6 implemented, WiFlow-STD MEASURED-EQUIVALENT ~96% PCK.
+5. **ADR-154/155/156/157** (beyond-SOTA sweeps) — `Proposed` but each describes fixes **already landed with revert-verified regression tests**.
+6. **ADR-024 (AETHER) / 027 (MERIDIAN) / 072 (WiFlow)** — `Proposed` but CLAUDE.md lists them Accepted and code references them as implemented.
+7. **ADR-017** — header Accepted but CLAUDE.md still calls it "Proposed" (inverse drift).
+8. **ADR-018** — `Proposed` but ADR-012 cites it as the working firmware/aggregator impl.
+
+#### SEVERITY: HIGH — Status ahead of its dependencies (Accepted depends on Proposed)
+
+- **ADR-032** Accepted → depends on Proposed 029/030/031.
+- **ADR-053** Accepted → depends on Proposed ADR-052.
+- **ADR-048** Accepted → depends on Proposed ADR-045.
+- **ADR-077** Accepted → depends on Proposed ADR-075/076.
+
+#### SEVERITY: MEDIUM — Proposed-but-looks-abandoned (decisions that will likely never land)
+
+Cluster heads where the whole chain is Proposed with zero implementation evidence:
+- **ADR-003/007/008/009/010** — RuVector child ADRs orphaned after parent ADR-002 was superseded by 016/017.
+- **ADR-105/106/107/108** — entire federation chain, none implemented.
+- **ADR-118/119/120/121/122/123** — entire BFLD chain, all ACs unchecked, tracking issues TBD.
+- **ADR-124/125/126/127/128/129/130/133** — HOMECORE/bridge chain, multi-quarter future-dated, all TBD.
+- **ADR-033** (remote-viewing), **ADR-042** (CHCI, superseded-in-intent by 153), **ADR-046** (Android TV), **ADR-049** (Python v1 legacy), **ADR-067** (RuVector v2.0.5 upgrade not adopted), **ADR-074** (SNN), **ADR-085** (RaBitQ expansion), **ADR-011** (Proposed-URGENT despite proof pipeline live).
+
+#### SEVERITY: MEDIUM — Accepted but no implementation evidence (unverified "done")
+
+- **ADR-034** (FieldView mobile app) — Accepted, no crate/dir in CLAUDE.md.
+- **ADR-044** (wifi-densepose-geo) — bare Accepted, no Date/Deciders, crate not in CLAUDE.md table.
+
+#### Ranked actionable backlog (do in this order)
+
+1. **Resolve 6 duplicate ADR numbers + 3 missing-header files** (CRITICAL — breaks the index/tooling). **Number collisions RESOLVED:** renumbered 147×2 (benchmark-proof→168, adam-mode→169), 148 (yoga→170), 149 (swarm-benchmarking→171), 050 (quality-engineering→166), 052 ddd appendix→167. Remaining: resolve the 134 identity split (done via G3→165); add Status headers to 168-proof, 134, 167-ddd (owner-gated).
+2. **Bulk-flip the 10 streaming-engine headers (ADR-136–145)** from Proposed → "Accepted — partial" — they have commit-pinned, test-backed Implementation Status notes. Highest ROI: one batch fixes the largest stale-status cluster.
+3. **Fix the status-graph inversions** (032/053/048/077 depend on Proposed parents; promote parents 029/030/031/045/052/075/076 to match their built reality, or downgrade the dependents).
+4. **Reconcile CLAUDE.md vs ADR headers** for 017, 024, 027, 072, 152 (doc says one thing, header another).
+5. **Triage the abandoned chains** (003/007–010, 105–108, 118–123, HOMECORE 124–133) — either mark `Rejected`/`Deferred` or open tracking issues; leaving ~50 Proposed-forever ADRs pollutes every gap analysis.
+6. **Verify or downgrade unsubstantiated Accepteds** (034, 044).
+
+**Bottom line:** the corpus's #1 defect is not abandoned work — it's **bookkeeping drift**. ~24 ADRs are mislabeled Proposed while code+tests exist, 6 numbers collide, and 3 files lack Status headers entirely. The status field cannot currently be trusted as a source of truth for what is built.

+
+## Lens 2: supersession-chains
+
+I have all evidence needed. ADR-016 doesn't mention ADR-002 at all (only 014/015); ADR-017 discusses ADR-002 as a "correction" but never uses the word "supersede." This confirms the broken reciprocity. Final analysis below.
+
+### Supersession & Lifecycle Integrity — ADR Corpus
+
+Total declared supersession edges in census: **3** (ADR-002→016, ADR-002→017, ADR-052-tauri→054). All three were file-verified. Findings below; severity graded **CRITICAL / HIGH / MEDIUM / LOW**.
+
+#### Reconstructed chains
+- **ADR-002** (RuVector RVF Integration Strategy) → superseded-by **ADR-016 + ADR-017** (dual realization). Self-declared `supersedes` on 016/017.
+- **ADR-052-tauri** (Tauri Desktop Frontend) → superseded-by **ADR-054** (declared in 052's `superseded_by`).
+- No other formal `supersedes`/`superseded_by` links exist. No cycles detected (the only multi-node graph, ADR-002→{016,017}, is a DAG; ADR-052→054 is a single edge). **No cycles — clean.**
+
+#### Broken / asymmetric links
+
+**1. ADR-002 → ADR-016 / ADR-017: one-directional, never reciprocated. (HIGH)**
+ADR-002 header declares "Superseded by [ADR-016] and [ADR-017]" (`docs/adr/ADR-002-ruvector-rvf-integration-strategy.md:4`). But neither successor claims it:
+- **ADR-016** (`ADR-016-ruvector-integration.md`) never mentions ADR-002 anywhere — its `## References` lists only ADR-014/015. It does not assert supersession; the census `supersedes:["ADR-002"]` for ADR-016 is **unsupported by the file**.
+- **ADR-017** (`ADR-017-ruvector-signal-mat-integration.md`) discusses ADR-002 only as a `## Correction to ADR-002 Dependency Strategy` (line 532) — corrects "fictional crate names" — but **never uses the word "supersede."** Census `supersedes:["ADR-002"]` is again file-unsupported.
+- Net: ADR-002 points up at two ADRs that don't point back. The supersession is asserted by the superseded ADR alone — backwards from convention, and unverifiable from the successors.
+
+**2. ADR-002 partial-supersession leaves 5 orphaned children stranded. (HIGH)**
+ADR-002 is an umbrella whose children ADR-003, 007, 008, 009, 010 are still `Proposed`. ADR-016/017 only realize the *training/signal/MAT* integration points (mincut, attention, solver, etc.). The RVF-container (003), PQ-crypto (007), Raft consensus (008), WASM edge runtime (009), and witness-chains (010) decisions are **neither implemented nor formally superseded** — ADR-017:555 explicitly acknowledges 008/009 "described in ADR-002" are not carried forward. Marking the parent fully "Superseded" silently buries 5 live-but-abandoned child decisions. ADR-010's role is additionally filled de facto by ADR-028's witness-bundle without any supersession link.
+
+**3. ADR-052-tauri → ADR-054: declared by predecessor, not acknowledged by successor. (HIGH)**
+Census records ADR-052-tauri `superseded_by:["ADR-054"]`. **ADR-054 (`ADR-054-desktop-full-implementation.md`) contains zero references to ADR-052** (grep for `ADR-052|replac|supersed` returns nothing). ADR-054 is titled "RuView Desktop **Full Implementation**" and is "in progress" — functionally it's the implementation plan *for* 052, not a replacement. The supersession edge is unconfirmed by the successor and arguably mis-modeled (an in-progress impl doesn't supersede its own design ADR).
+
+#### Orphaned superseded ADRs still marked accepted/active
+**4. No classic orphan (superseded ADR still `Accepted`), but two soft variants: (MEDIUM)**
+- **ADR-052-tauri** is `Proposed` *and* `superseded_by ADR-054`, yet downstream ADR-053/055/056 (all `Accepted`) build on it and treat the desktop app as shipped (v0.3.0). A Proposed-and-superseded ADR anchoring three Accepted descendants is a lifecycle inconsistency: the live decision-of-record is ambiguous (052? 054? 056?).
+- **ADR-002** is correctly `Superseded`, so not an orphan — but ADR-038's roadmap census still counts it among 37 active ADRs, so stale references persist downstream.
+
+#### De-facto supersessions never recorded (missing links) — MEDIUM
+These pairs behave as supersession in the corpus but carry **no** `supersedes`/`superseded_by` fields, so the chain graph understates reality:
+- **ADR-098 ⇄ ADR-099** (`MEDIUM`): ADR-098 **Rejected** midstream; ADR-099 revives its carve-outs ("Adopt midstream…"). A rejection partially reversed by a later Proposed ADR — neither links the other via supersession fields (only prose tension).
+- **ADR-063 → ADR-064**, **ADR-035 → ADR-023/036**, **ADR-042 → ADR-153**, **ADR-050-provisioning → ADR-060**, **ADR-117 retracts PyPI v1.1.0**, PQ chain **ADR-100 → ADR-109 / ADR-107→108**: each is "superseded in scope/intent" per flags but has empty supersession fields. Not broken links (none falsely asserted), but **missing** ones — the lifecycle graph is incomplete.
+
+#### Cycles
+**None.** ADR-002→{016,017} and ADR-052→054 are acyclic; no ADR is reachable from its own successor.
+
+#### Severity summary
+| # | Issue | Severity |
+|---|-------|----------|
+| 1 | ADR-002 supersession not reciprocated by ADR-016/017 (016 never mentions 002; 017 only "corrects") | HIGH |
+| 2 | ADR-002 children 003/007/008/009/010 stranded under a "fully superseded" parent | HIGH |
+| 3 | ADR-052→054 edge unacknowledged by ADR-054 (no reference); likely mis-modeled (impl, not replacement) | HIGH |
+| 4 | ADR-052-tauri Proposed+superseded yet anchors Accepted 053/055/056 | MEDIUM |
+| 5 | De-facto supersessions (098/099, 063/064, 042/153, 050/060, 035/023, 100/109) unrecorded | MEDIUM |
+| — | Cycles | none (clean) |
+
+Highest-priority fix: add reciprocal `supersedes: ADR-002` language to ADR-016/017 (or downgrade the claim), and split ADR-002's status to "partially superseded" so children 003/007/008/009/010 aren't silently closed.

+
+## Lens 3: contradictions
+
+All findings confirmed against source. Here is the contradictions lens.
+
+### Contradictions & Retractions Lens — ADR Corpus
+
+The sweep (ADR-154–163) is itself a structured retraction layer: each "Beyond-SOTA / anti-AI-slop" ADR exists *because* an earlier accepted claim was found false. Findings graded **CRITICAL** (life-safety, security, or a published accuracy number that was meaningless) / **HIGH** (a capability/number retracted or directly contradicted) / **MEDIUM** (status or scope conflict) / **LOW** (cosmetic/doc drift).
+
+#### A. Accepted/published claims later RETRACTED or REFUTED
+
+**[CRITICAL] ADR-155 retracts every prior NN accuracy/TTA/proof claim.** ADR-155 §2.2 discloses `bin/train.rs` validated a *real* MM-Fi training run against a **synthetic** val set, and windows leak at stride-1 (~99% overlap) — *"any PCK it printed was meaningless on two counts."* §2.3: `rapid_adapt.rs` `contrastive_step`/`entropy_step` wrote a **fake gradient** (`grad += v * 0.01`) unrelated to the objective — every "TTA improves the metric" result was unsupported. §2.4: the deterministic proof **self-certified** (`generate_expected_hash` blessed whatever the pipeline emitted; PASS counted any loss decrease incl. 1e-9 float noise; missing hash defaulted to PASS). This retroactively voids accuracy claims made anywhere in the corpus that depended on the training/proof path prior to commit landing ADR-155.
+
+**[CRITICAL] ADR-154 retracts the ADR-134 CIR coherence gate as live.** ADR-152/CLAUDE.md present CIR (ADR-134) as a contributing signal in the multistatic coherence gate. ADR-154 §2 proves it was **DEAD in production for every canonical frame**: the HT20 CIR estimator returns `SubcarrierMismatch` on all 56-tone canonical frames (`cir_gate_ht20_is_dead_on_canonical56`: 0 Ok / 8 mismatch), so `coherence = 0.7·freq + 0.3·dominant_tap_ratio` silently degraded to freq-only (`cir_gate_dead_ht20_equals_gate_off`, |Δ|<1e-9). Any ADR claiming CIR-enhanced coherence/ToF before this fix overstated reality.
+
+**[CRITICAL] ADR-079 internal accuracy contradiction (self-flagged in census, confirmed).** Context states proxy PCK@20 = **2.5%** (lines 11, 25) and "10-20x improvement: 2.5% → 35%+". The baseline table (line 497) reports proxy PCK@20 = **35.3%** — i.e. the *baseline already equals the stated target* — while per-joint upper body (nose/shoulders/wrists) is **0%** (line 503). The headline 10–20x improvement number is therefore self-refuting against its own baseline table. CLAUDE.local.md adds the local-Windows attempt (#640) measured **0% PCK**. An Accepted ADR with three mutually inconsistent values for its own central metric.
+
+**[HIGH] ADR-152 self-refutes one verified research claim (F4).** ADR-152 grades 25 claims 3-vote; §F4 records the "Espressif `esp_wifi_sensing` is **drop-in compatible with RuView nodes**" claim **REFUTED 0-3** (WiFi-6 parts use a different CSI acquisition config struct). ADR-110 ("ESP32-C6 Wi-Fi 6 CSI") and the CLAUDE.md hardware table treat C6/Wi-Fi-6 CSI as a smooth extension; ADR-152 also notes HE-CSI needs ESP-IDF ≥5.5 (v5.4 silently downconverts to HT). The "WiFlow-STD MEASURED-EQUIVALENT ~96% PCK@20" line in CLAUDE.md is *not* yet supported: §2.2/§F1 mark external pose numbers (incl. the 97.25% WiFlow-STD figure) **CLAIMED**, and §F1 explicitly forbids citing 97.25% as comparable until measurements (a)–(c) are run. CLAUDE.md asserting "MEASURED-EQUIVALENT" contradicts the ADR's own gating.
+
+**[HIGH] ADR-150 retracts the implied cross-subject capability of the encoder line.** AETHER/MERIDIAN ADRs (024/027) and the foundation-encoder framing imply subject-invariant embeddings work. ADR-150 measures **81.63% in-domain vs ~11.6% leakage-free cross-subject** torso-PCK, and reports DANN **failed** (27.26%→27.54%, empirically ~0 gain) and bigger capacity *hurt* (transformer 24.8% < conv 27.3%). §1.1/§4 conclude the cross-subject acceptance gate "is **unlikely to be met without new multi-subject** data" — a direct retraction of the "more capacity / adversarial alignment solves cross-environment loss" premise underlying ADR-027.
+
+**[HIGH] ADR-159 refutes the "never identified anyone" accusation but simultaneously retracts cog-person-count's marketing.** ADR-159 ships real SHA-pinned Candle models, but discloses person-count `training_class1_accuracy = 0.343` (presence-only, classes 0/1), and **renames** the Cargo description from "learned multi-person counter" → "presence detector + (data-gated) person count," clamping/`low_confidence`-flagging multi-occupant counts. This retracts ADR-103's "learned multi-person counter (SOTA WiFi CSI counting)" claim and ADR-104's count tool, which depended on it.
+
+**[HIGH] ADR-161 retracts HOMECORE server security + functionality claims.** ADR-130 (HOMECORE-API, wire-compatible, Ed25519-JWT) implied a secured server. ADR-161 fixes a **CRITICAL WebSocket auth bypass** (any non-empty token accepted), "reply-theater" (WS responses computed then discarded), and documented-but-no-op automation — then ADR-162 enforces the ADR-161 deferrals (plugin Ed25519 sig verification, capability isolation, bounded RunModes that were "parsed-but-unenforced/unbounded-parallel"), retracting ADR-128/129's implied plugin-signing and automation guarantees.
+
+**[MEDIUM] ADR-163 converts CLAIMED latency budgets to MEASURED — retracting prior budget citations.** ADR-160/159 cited wasm-edge/cog latency *budgets*. ADR-163 adds host benches and explicitly states the **ESP32/Xtensa-on-hardware figure remains UNMEASURED** — so any doc citing the device latency budget as achieved is unsupported.
+
+**[MEDIUM] ADR-098 → ADR-099 partial reversal.** ADR-098 **Rejected** midstream as a system component; ADR-099 (Proposed) **adopts** midstream's temporal-compare (DTW) + temporal-attractor-studio as a parallel tap. Framed as "complementary," but it revives the exact carve-outs ADR-098 declined to integrate — a live decision conflict pending resolution.
+
+**[MEDIUM] ADR-147 (OccWorld) self-retracts Cosmos.** The accepted ADR-147 title/decision was revised from "NVIDIA Cosmos WFM Integration" to OccWorld after a hardware finding (Cosmos needs 32.5 GB VRAM); Cosmos is retracted as primary. The companion ADR-168-benchmark-proof (renumbered from ADR-147) reports 213 ms/inference on **random weights, no checkpoint** — a baseline-without-fine-tuning number that must not be cited as a quality/target metric.
+
+#### B. Pairs making CONFLICTING decisions on the same topic
+
+**[HIGH] RVF-WASM edge runtime — ADR-009 vs shipped `wifi-densepose-wasm`.** ADR-009 (Proposed) decides to **replace** the existing wifi-densepose-wasm approach with an `.rvf.edge` container runtime. The crate it proposes to replace is shipped and in the CLAUDE.md crate table (and is the dependency base for ADR-058/059 browser pose). ADR-009 is an unrealized decision directly contradicting shipped architecture.
+
+**[HIGH] Witness/audit mechanism — ADR-010 vs ADR-028.** ADR-010 (Proposed) decides RuVector witness *chains* as "the primary tamper-evident audit mechanism." ADR-028 (Accepted, implemented) established a different **witness-bundle** mechanism (verify.py / SHA-256 / VERIFY.sh) that fills this role. Two competing "primary audit" decisions; ADR-010 is stranded.
+
+**[HIGH] Multistatic "sensing-first RF mode" — ADR-029 vs ADR-031 near-duplicate scope.** Both decide a "sensing-first RF mode for multistatic fidelity": ADR-029 (RuvSense, signal/src/ruvsense/) and ADR-031 (RuView cross-viewpoint fusion, ruvector/src/viewpoint/). Overlapping problem statements (occlusion/depth/multi-person via multistatic attention+geometry), separate crate homes, both still nominally "Proposed" while both are implemented. Unreconciled dual ownership of the multistatic-fusion decision.
+
+**[MEDIUM] Person-counting decision conflict — ADR-037 vs ADR-075 vs ADR-103.** Three different decisions to replace the same fixed-threshold counter: ADR-037 (4-phase neural decomposition), ADR-075 (spectral min-cut over subcarrier-correlation graph, fixes #348), ADR-103 (learned Cog `cog-person-count`). ADR-075's bug (#348) overlaps ADR-069's driver. None supersedes the others; ADR-159 then guts ADR-103's claim (above).
+
+**[MEDIUM] PQ-crypto signing — ADR-007 vs ADR-109.** ADR-007 (Proposed) decides Ed25519 + ML-DSA-65 hybrid for sensing-data signing; ADR-109 (Proposed) decides Ed25519 + **Dilithium-3** hybrid for cog signing (Dilithium = ML-DSA family but a different parameter pick/scope). Two PQ-signature decisions over adjacent surfaces with non-identical algorithm choices, neither reconciled.
+
+**[MEDIUM] Federation key-exchange self-supersession — ADR-107 vs ADR-108.** ADR-107 adopts classical Diffie-Hellman in secure-aggregation Layer 4; ADR-108 replaces it with Kyber-768 because the DH choice is "quantum-vulnerable." ADR-108 supersedes a core element of ADR-107 while ADR-107 is still only Proposed — a decision corrected before it was ever accepted.
+
+**[MEDIUM] Provisioning path forked three ways — ADR-050(prov) vs ADR-060 vs ADR-052/054.** ADR-050 (provisioning-tool-enhancements, Proposed) scopes channel+MAC-filter flags; ADR-060 (Accepted) actually implements them; ADR-052/054 move provisioning into a Rust-native Tauri desktop path. Three live decisions for "how RuView provisions nodes," with ADR-060 partially fulfilling ADR-050 without superseding it.
+
+#### C. Status-graph contradictions (Accepted depending on / contradicting Proposed)
+
+**[MEDIUM] Accepted ADRs hardening/depending on Proposed ones.** ADR-032 (Accepted, security hardening) hardens ADR-029/030/031 which remain "Proposed" — an accepted decision presupposing un-accepted ones exist. Same pattern: ADR-048 (Accepted) depends on ADR-045 (Proposed); ADR-053 (Accepted) depends on ADR-052 (Proposed); ADR-077 (Accepted) depends on ADR-075/076 (Proposed); ADR-104 (Accepted) depends on ADR-103 (Proposed). These are status contradictions, not capability retractions, but they signal the same "header lags reality" hygiene problem the sweep is correcting.
+
+**[LOW] Header-stale-vs-implementation (pervasive).** ADR-029/030/031, 072, 095/096, 136–145, 150, 152, 154–157 all carry `Status: Proposed` while their own appended Implementation-Status notes (or downstream ADRs / CLAUDE.md) report them built+tested with commits. ADR-024/027 say Proposed; CLAUDE.md lists them Accepted; pose_tracker.rs already uses AETHER re-ID. Cosmetic but corpus-wide; it is the mechanism by which retracted/overstated claims survive (a green "built" note under a "Proposed" header is exactly where ADR-155's self-certifying proof hid).

+**Top-severity summary:** the four CRITICAL items (ADR-155 fake-gradient+synthetic-val+self-certifying proof; ADR-154 dead CIR gate; ADR-079 self-inconsistent PCK; ADR-161 WS auth bypass) are the corpus's load-bearing "AI-slop" admissions — each is an *accepted-or-shipped* surface whose stated accuracy/security/function was provably false until the sweep landed. Every accuracy number predating ADR-155 in any other ADR should be treated as CLAIMED, not MEASURED, until re-derived through the post-155 leak-free split.

+
+## Lens 4: coverage-gaps
+
+Confirmed — ADR-094 governs the pointcloud *viewer deployment* (proposed-only), not the crate's sensing-data-production contract. I have all evidence needed.
+
+### Coverage Gaps — Crates/Capabilities vs Governing ADRs
+
+Severity: **CRITICAL** (shipped code with no/broken governing ADR), **HIGH** (architect would expect an ADR, none exists), **MEDIUM** (governed only by a remediation/deploy ADR, no creation/architecture ADR), **LOW** (minor).
+
+#### A. Shipped crates whose cited ADR does not exist (CRITICAL)
+
+Two crates are built and in-tree but reference ADR numbers that point to *different* on-disk ADRs or to files that never existed (confirmed: no `ADR-131*.md` or `ADR-132*.md` exists; `ADR-134` on disk is CIR, not HOMECORE-MIGRATE):
+
+- **`v2/crates/homecore-recorder`** — Cargo.toml header: *"SQLite state history + semantic search (ADR-132)"*. **No ADR-132 exists.** The HOMECORE series map (ADR-126 §4) lists ADR-132 HOMECORE-RECORDER as planned, but it was never written. A shipped persistence/history crate has zero governing decision record. **CRITICAL** — this is the recorder, the durable-state surface, ungoverned.
+- **`v2/crates/homecore-migrate`** — Cargo.toml header: *"Implements ADR-134 (HOMECORE-MIGRATE)"*. **On-disk ADR-134 is "First-Class CIR Support"** (census + glob confirm). ADR-129/126 also cite ADR-134 as HOMECORE-MIGRATE. The crate implements a migration tool from Python HA reading `.storage/*.json` — a data-integrity-sensitive importer — governed by a phantom ADR identity. **CRITICAL** (compounds the documented ADR-134 duplicate-number collision).
+
+These are not stale-header issues like the ADR-136..146 cluster (where the ADR exists and is just marked Proposed); here the cited governing ADR **is absent or is a different decision**.
+
+#### B. Shipped crates with NO governing ADR at all (HIGH)
+
+- **`v2/crates/wifi-densepose-engine`** — *"streaming-engine integration layer — composes the ADR-135..146 building blocks into one trust-traceable pipeline cycle."* It composes ~12 ADRs' outputs into the live pipeline-cycle aggregate, but **no ADR governs the composition/orchestration contract itself** (ordering, back-pressure, the "one pipeline cycle" boundary). ADR-136 defines frame contracts/stages but not the integrator crate. An architect would expect an ADR for the seam that wires 135–146 onto the live 20 Hz path — exactly the "integration glue not yet on live path" caveat repeated across ADR-136..146. **HIGH.**
+
+#### C. Capabilities governed only by a remediation/deploy ADR — no creation/architecture ADR (MEDIUM)
+
+- **`v2/crates/wifi-densepose-wasm-edge` (~70 edge skills)** — The only ADRs touching it are **ADR-160** (honest *relabeling*/soundness cleanup) and **ADR-163** (latency *measurement*). Both are anti-slop remediation ADRs that presuppose ~70 skills already shipped. There is **no creation/architecture ADR** defining the skill taxonomy, ABI, event-ID allocation, or budget tiers for this crate. (Contrast ADR-041, which *does* catalog the 60-module registry — but for the ESP32/WASM3 on-device path of ADR-040, a different artifact.) A whole ~70-module crate's design rationale lives nowhere. **MEDIUM-HIGH.**
+- **`v2/crates/wifi-densepose-occworld-candle`** — *"OccWorld TransVQVAE inference ported to Candle (Rust-native, no Python IPC)."* ADR-147 (OccWorld) decided a **Python-subprocess** thin client and explicitly deferred a Rust backend swap to "Phase B / RoboOccWorld." A native Candle reimplementation is a material architecture change (new dep surface, no IPC, weight-loading path) that **no ADR records the decision to build now**. **MEDIUM.**
+- **`v2/crates/wifi-densepose-pointcloud`** — ADR-094 governs only the *GitHub-Pages viewer deployment* (Proposed). The crate as a **point-cloud data-production/format contract** (what it emits, schema, real-data-stream toggle wiring) has no governing decision beyond the demo-deploy doc. **MEDIUM.**
+- **`v2/crates/homecore-hap`** — header cites ADR-125 P1 scaffold; ADR-125 (Apple Home HAP bridge) exists and covers it. **Governed — no gap.** (Listed to scope out the false positive.)
+- **`v2/crates/wifi-densepose-geo`** — governed by ADR-044 (geospatial). Governed, but ADR-044 is a bare "Accepted" with no implementation evidence and is cross-referenced incorrectly by ADR-052 (cites ADR-044 for provisioning). **LOW** (governed but the ADR itself is thin).
+
+#### D. Decision areas an architect would expect an ADR for, but none exists (HIGH)
+
+1. **Persistence/storage strategy for HOMECORE state history** — `homecore-recorder` ships SQLite with an "HA-compat schema," but no ADR decides SQLite-vs-alternatives, retention, or the semantic-search index. Recorder is the durability backbone; an unrecorded storage choice is a classic missing-ADR. **HIGH** (ties to gap A).
+2. **Python-HA → HOMECORE migration/import contract** — `homecore-migrate` reads foreign `.storage` JSON (untrusted input, schema-drift risk) with no governing ADR (the cited one is CIR). Migration correctness and trust boundary are exactly what an ADR should pin. **HIGH** (ties to gap A).
+3. **The streaming-engine *integrator* contract** (`wifi-densepose-engine`) — see B. **HIGH.**
+4. **Cross-crate workspace dependency/publishing ADR** — CLAUDE.md lists a hand-maintained 12-step publishing order and a 15-crate table, but the workspace now has **38 crates** (glob count) including ungoverned ones (engine, worldmodel, worldgraph, occworld-candle, geo, wasm-edge, homecore-*, cog-*, ruview-swarm, pointcloud, nvsim-server, desktop). No ADR governs crate-graph topology / publish boundaries at this scale — the publishing list in CLAUDE.md is already stale against reality. **MEDIUM-HIGH.**
+5. **No ADR ties the streaming-engine (`engine`) to the cog/appliance deploy surface** — ADR-101/102/159 govern cogs; ADR-136..146 govern the engine; nothing decides how the trust-traceable engine output becomes a deployed cog. The seam between the two largest subsystems is ungoverned. **MEDIUM.**
+
+#### E. Scoped-out false positives (verified governed)
+

+#### Top-priority remediation (concrete)
+1. Write **ADR-132 HOMECORE-RECORDER** (or renumber) so the shipped `homecore-recorder` SQLite/history crate has a real governing decision — **CRITICAL**.
+2. Resolve the **ADR-134 identity collision** and create a real **HOMECORE-MIGRATE** ADR for `homecore-migrate` (untrusted-import trust boundary) — **CRITICAL**.
+3. Write a **streaming-engine integrator ADR** for `wifi-densepose-engine` (the 135–146 composition contract / live-path seam) — **HIGH**.
+4. Write a **creation/architecture ADR for `wifi-densepose-wasm-edge`** (taxonomy/ABI/event-IDs) — currently only remediation ADRs (160/163) exist — **MEDIUM-HIGH**.
+5. Add an ADR for the **`occworld-candle` Rust-native backend swap** (ADR-147 only blessed the Python-subprocess path) — **MEDIUM**.
+
+Evidence files: `v2/crates/homecore-recorder/Cargo.toml`, `v2/crates/homecore-migrate/Cargo.toml`, `v2/crates/wifi-densepose-engine/Cargo.toml`, `v2/crates/wifi-densepose-occworld-candle/Cargo.toml`, `docs/adr/ADR-134-csi-to-cir-time-domain-multipath.md` (CIR, not MIGRATE), `docs/adr/ADR-160-edge-skill-library-honest-labeling.md`, `docs/adr/ADR-094-pointcloud-github-pages-deployment.md`; absence confirmed via glob: no `ADR-131*`, no `ADR-132*`.

+## Lens 5: data-hardware-gated
+
+Evidence confirmed. I have enough to write the section.
+
+### Open / Gated Decisions — The Real Backlog (data/hardware-gated, in-progress, or unresolved)
+
+Severity = how load-bearing the unresolved decision is to a shipped claim. Sweep coverage = whether ADR-154–163 touched it.
+
+#### CRITICAL — life-safety or shipped-claim surface, still gated
+
+**ADR-079 — Camera Ground-Truth Training Pipeline.** *Accepted, but core decision unvalidated.* P7–P9 (real paired-data collection, training, cross-room LoRA) are **Pending** (file lines 476–478). Blocker: a real synchronized camera+ESP32 paired-capture session and GPU training run — neither done. The ADR's own baseline table is self-contradictory: text says proxy PCK@20=2.5% (lines 11, 25) yet line 497 reports 35.3% (the *target*) with line 503 confessing **upper-body joints at 0%** — the proxy has no real spatial signal. CLAUDE.local.md records the local-Windows attempt (#640) at 0% PCK. The fleet (ruvultra RTX 5080, cognitum-seed-1) is the unblock, but the decision is accepted-on-paper, not proven. **Sweep: NOT addressed** — 154–163 never touch the camera-teacher path. Real open backlog item.
+
+**ADR-158 — MAT/World-Model sweep (life-safety).** *Accepted/implemented for the correctness fixes, but capability remains DATA-GATED.* The sweep honestly fixed the dangerous bugs (unified the two divergent triage engines so survivor count can't inflate from repeat detection — lines 46–56, 184–186), but explicitly grades the actual capabilities as unproven: **RF-through-rubble survivor detection = DATA-GATED** (needs instrumented rubble trials, line 37); **learned multi-person counter = DATA-GATED** on labelled multi-occupant CSI (lines 41, 173); PicoScenes/Intel-5300/Atheros live capture DATA-GATED on NIC/driver hardware (lines 177–179). **Sweep: addressed the slop, honestly deferred the capability.** This is the model the rest should follow — code is real, accuracy claim is withheld pending absent hardware. Severity CRITICAL because it is the life-safety surface; the residual gate is acceptable and labeled.
+
+#### HIGH — shipped/benchmarked claim with an explicit residual gate
+
+**ADR-152 — WiFi-Pose SOTA 2026 Intake.** Status header stale (says Proposed; commits + line 58 report §2.1–2.3/2.6 implemented and WiFlow-STD **MEASURED-EQUIVALENT 96.09% PCK@20** on RTX 5080). Residual gates are real and disclosed: (1) **1 of 25 verified claims REFUTED 0-3** — "ESP WiFi-6 drop-in compatible with RuView nodes" is false (WiFi-6 parts use a different CSI acquisition struct, lines 31, 123); (2) external pose numbers (PerceptAlign −60% cross-domain; UNSW MAE pose transfer) remain **CLAIMED until reproduced on our hardware** (lines 21, 27, 119–122); (3) measurement (b)/(c) open — line 111 confirms pretrained init gives optimization transfer but **no feature transfer**, and no run beat a mean-pose baseline on single-subject data, so **no CSI→pose capability is citable** until multi-subject/multi-position data exists. Blocker: heterogeneous multi-subject CSI dataset (data-gated, per ADR-150 §F3). **Sweep: this ADR *is* the prove-everything discipline applied to research intake** — gates labeled, not buried.
+
+**ADR-072 / ADR-150 — WiFlow pose + RF foundation encoder.** ADR-072 >80% PCK@20 target unverifiable without camera labels (resolved-path via ADR-079, itself gated above). ADR-150 cites measured 81.63% in-domain vs **~11.6% leakage-free cross-subject** — the cross-subject collapse is real and the stated lever (ADR-152 F3) is *more heterogeneous data*, not capacity. Blocker: multi-subject/room dataset + libtorch GPU training. **Sweep: NOT directly addressed** (155 fixed PCK/OKS metric-integrity plumbing, which makes these numbers *trustworthy* but doesn't close the data gap).
+
+#### HIGH — security/privacy decisions still Proposed-only (no sweep touched the gate itself)
+
+**ADR-080 — QE Remediation.** Tracks unfixed security HIGH findings (X-Forwarded-For bypass, leaked stack traces, JWT-in-URL CWE-598), gate FAILED, status Proposed, no done-marking. The HOMECORE sweep (ADR-161/162) fixed *HOMECORE*'s WS-auth bypass and plugin signing — a **different** server boundary. **Sweep: did NOT cover ADR-080's sensing-server findings.** Genuine open security backlog.
+
+**ADR-105→109, ADR-118–125 (BFLD/federation/fabric chains).** Entire federation chain (105–109) and BFLD surface (118–125) are Proposed-only, all ACs unchecked, several "tracking issue TBD." Blockers: KIT BFId dataset (ADR-121 calibration), Pi5/Nexmon CBFR capture hardware (ADR-123 — ESP32 *structurally cannot* sniff CBFR), Soul-Signature + cog-ha-matter dependencies (ADR-122/125). **Sweep: NOT addressed** — 154–163 stop at HOMECORE/MAT/cog/edge; the privacy control *plane* (ADR-141, built) exists but the BFLD *capture/scoring* chain it would gate does not. Backlog, honestly gated by absent hardware.
+
+#### MEDIUM — hardware-gated, honestly deferred BY the sweep (lowest risk)
+
+**ADR-163 — Edge-latency measurement.** *Accepted/implemented* for host benches, but the **ESP32/Xtensa on-hardware `process_frame` figure is explicitly UNMEASURED / PENDING (hardware)** (lines 31–32, 79–83, 92–93). Blocker: `wasm32-unknown-unknown` built + flashed to ESP32-S3 and timed on-device; host x86_64 median is "an upper bound on algorithm work, not the ESP32 number." This is the **gold-standard deferral**: the gate is stated everywhere, no claim overreaches. **Sweep: this *is* a sweep ADR honestly deferring its own residual.**
+
+**ADR-160 — wasm-edge skill labeling.** Medical/affect/weapon capabilities explicitly **NOT validated** — relabelled/disclaimed/feature-gated rather than implemented, reference-standard-gated. **Sweep: addressed by relabeling, capability honestly deferred.**
+
+**ADR-110 — ESP32-C6 firmware.** Implemented, but HE-CSI requires ESP-IDF ≥5.5 (v5.4 silently downconverts to HT) — capability hardware/toolchain-gated per WITNESS §B1. Not a sweep target; gate is a noted hardware constraint, not slop.
+
+**Other purely hardware/data-gated Proposed decisions (no sweep involvement, no overreach):** ADR-023 (paired data+GPU), ADR-027/MERIDIAN (multi-env data), ADR-042 CHCI (custom PCB/TCXO — largely superseded by 153), ADR-063/064 (ESP32-C6+MR60BHA2 mmWave), ADR-065/066 (live Cognitum Seed deploy), ADR-070 (live 2-node+Seed capture), ADR-073/078 (multi-AP mesh deployment), ADR-083 (pending field evidence), ADR-086 (real-deployment suppression rates), ADR-091 (COTS sub-THz + ITAR-clear use case), ADR-103 (labelled count data), ADR-113 (Fresnel-sim, not hardware-validated), ADR-114 (real NV-diamond device), ADR-134/135 (COM9/COM12 hardware-test feature), ADR-143 v2 (7-day fleet validation campaign, dead-code until then), ADR-144 (no UWB radio in fleet).
+
+#### Cross-cutting finding
+The sweep (ADR-154–163) is **narrowly scoped**: it hardened MAT (158), Cognitum cogs (159), wasm-edge (160), HOMECORE server+plugins (161/162), and latency debt (163) — converting CLAIMED→MEASURED or DATA-GATED with honest labels. It **did not** touch the two largest *capability* gaps: the **camera-teacher training validation (ADR-079/072/150)** and the **federation/BFLD privacy chains (105–109, 118–125)** — both remain data/hardware-gated and Proposed-only. The single hard contradiction worth flagging to a human: **ADR-079's baseline table reports the target (35.3%) as if achieved while the prose and #640 evidence say 2.5%/0%** — that is the one place a reader could mistake an aspiration for a measurement.

+//! Criterion bench for `cog-person-count` steady-state inference latency
+//! (ADR-163, closing the ADR-159/160 deferred "cog inference latency bench" item).
+//!
+//! ## What this measures — and what the manifest's `cold_start_ms` does NOT
+//!
+//! This benches **steady-state** `InferenceEngine::infer` over a FIXED CSI
+//! window on `Device::Cpu` with the **real** shipped `count_v1.safetensors`
+//! weights — i.e. the per-frame cost once the model is loaded and warm.
+//!
+//! The cog manifest's `build_metadata.cold_start_ms_avg` (in the pose cog;
+//! person-count's manifest carries comparable provenance) is a **DIFFERENT
+//! measurement**: it includes one-time weight load / mmap / first-forward
+//! allocation. Cold-start is a startup cost paid once; steady-state infer is the
+//! recurring per-frame cost. They are not comparable and we do not conflate them.
+//! `cold_start` was measured on ruvultra (RTX 5080 host, candle 0.9 cpu); this
+//! bench runs on whatever machine you run it on — see `benchmarks/edge-latency/RESULTS.md`
+//! for the host the committed numbers were taken on.
+//!
+//! If the weights file is absent the engine falls back to the zero-confidence
+//! stub; we skip the bench in that case rather than benchmark the stub (which
+//! would be a meaningless number) — the bench prints a notice and measures a
+//! no-op so criterion still produces a (clearly-labelled) datapoint.
+//!

+//! Criterion bench for `cog-pose-estimation` steady-state inference latency
+//! (ADR-163, closing the ADR-159/160 deferred "cog inference latency bench" item).

+//! ## What this measures — and what the manifest's `cold_start_ms_avg` does NOT
+//!
+//! The pose cog's manifest (`cog/artifacts/manifests/x86_64/manifest.json`)
+//! cites `build_metadata.cold_start_ms_avg: 5.4` (30 invocations, measured on
+//! ruvultra / RTX 5080 host, candle 0.9 cpu). **That is a cold-start number** —
+//! it folds in one-time weight load / mmap / first-forward allocation.
+//!
+//! This bench measures the **steady-state** per-frame cost instead:
+//! `InferenceEngine::infer` over a FIXED CSI window on `Device::Cpu` with the
+//! **real** shipped `pose_v1.safetensors`, after a warm-up forward. Steady-state
+//! and cold-start are different measurements; we label both honestly and do not
+//! claim this reproduces the 5.4 ms manifest figure (different machine, different
+//! measurement). See `benchmarks/edge-latency/RESULTS.md`.

+//! Deterministic text embedding for semantic intent matching.
+//!
+//! No ML model dependency: utterances are embedded with the classic
+//! **feature-hashing** (hashing-vectorizer) technique. Each n-gram feature is
+//! hashed into a fixed-width vector; a second sign-hash decides whether the
+//! feature adds or subtracts, which keeps the expected dot-product unbiased
+//! under collisions. The vector is L2-normalised so that cosine similarity is
+//! a clean `1 - distance`.
+//!
+//! Features used per utterance:
+//! - **word unigrams** — whole tokens after lowercasing/trimming punctuation.
+//! - **character trigrams** — sliding 3-grams over each padded token, which
+//!   gives partial-overlap credit ("kitchen" ~ "kitchens") and robustness to
+//!   small lexical variation.
+//!
+//! This is intentionally *lexical-semantic*: paraphrases that share tokens
+//! ("turn on the light" vs "turn on the kitchen light") land close together,
+//! while unrelated utterances ("play jazz music") land far apart. It is a real,
+//! reproducible similarity signal — not a hash that ignores meaning.

+//! Embeds utterances with [`crate::embedding`] (deterministic feature hashing)
+//! and runs an **exact in-memory cosine k-NN** over enrolled intent exemplars.
+//! On a match above the similarity threshold the exemplar's intent is returned,
+//! with slots extracted from the incoming utterance via an optional paired
+//! regex. Below threshold (or with an empty index) it delegates to the inner
+//! [`RegexIntentRecognizer`](crate::recognizer::RegexIntentRecognizer).
+//!
+//! For the small intent vocabularies HOMECORE deals with, an exact cosine scan
+//! is both faster and far more robust than an external ANN index — it has no
+//! storage backend, no cross-crate feature coupling, and is fully deterministic.
+//! Embeddings are L2-normalised, so cosine similarity is a plain dot product.
+//!
+//! Gated behind the default-on `semantic` feature. When disabled, a thin
+//! delegating wrapper keeps the public type available.

 //! ADR-129 §2 design: one Tokio task per running automation instance.
-//! RunMode::Single is enforced via a per-automation `AtomicBool` flag.
+//!
+//! ## Run modes (ADR-161 §A5 → completed in ADR-162)
+//!
+//! Each registered automation owns a [`RunState`] that implements its
+//! `RunMode`: `Single`/`IgnoreFirst` skip re-entrant triggers, `Restart`
+//! aborts the in-flight run and starts a fresh one, `Queued` serializes
+//! runs in arrival order (nothing dropped), `Parallel` spawns on every
+//! trigger, and `max: N` caps concurrency via a per-automation semaphore.
+//! (ADR-161 only honored Single/Parallel; Restart/Queued/max were
+//! honestly documented as unbounded-parallel until ADR-162.)
+//!
+//! ## Time triggers (ADR-161, HC-WS-04)
+//!
+//! `Trigger::Time { at: "HH:MM:SS" }` is evaluated by a wall-clock timer
+//! task (1 Hz tokio interval) — `Trigger::matches_sync` returns false for
+//! `Time` because it has no clock. The timer fires each `time:`
+//! automation once when the local wall-clock second equals its `at`.
+//!
+//! ## Template conditions (ADR-161, HC-WS-07)
+//!
+//! The engine builds a real [`TemplateEnvironment`] over the state
+//! machine and passes it into every `EvalContext` (via
+//! `EvalContext::with_templates`), so `template:` conditions evaluate
+//! against live state instead of always returning false.

+//! Plugin authority / capability isolation (ADR-162, P5).
+//!
+//! Wasmtime already gives a plugin **memory** isolation — it cannot read
+//! another plugin's linear memory. It does NOT, by itself, stop a plugin
+//! from using a host import to write any entity it likes. Before this fix
+//! `hc_state_set` happily let any plugin write `lock.front_door` or
+//! `alarm_control_panel.*`, and the manifest's `homecore_permissions`
+//! claims were parsed but **never consulted** (ADR-161 deferred P5).
+//!
+//! This module adds **authority isolation**: a plugin may only write
+//! entities its manifest declared. The host import consults a
+//! [`PermissionSet`] before applying any state write and returns a typed
+//! error to the guest (it does **not** panic the host) on a violation.
+//!
+//! ## Permission grammar
+//!
+//! Each entry in `homecore_permissions` is one of:
+//!
+//!   * a bare entity glob — `"light.*"`, `"light.kitchen"`, `"*"`;
+//!   * the explicit capability form `"state:write:<glob>"` (the form the
+//!     ADR-128 manifest doc shows), e.g. `"state:write:sensor.*"`.
+//!
+//! A glob supports a single trailing `*` (HA-style domain wildcards:
+//! `light.*` matches every `light` entity) and a leading-or-bare `*`
+//! (`*` = everything). Exact strings match exactly. A plugin with **no**
+//! `state:write` entries can write **nothing** — the secure default.

+//! Plugin signature & integrity verification (ADR-162, P4).
+//!
+//! ADR-161/B5 honestly relabelled the manifest's `wasm_module_hash` /
+//! `wasm_module_sig` / `publisher_key` fields as "(P4 — not yet enforced)":
+//! they were parsed and round-tripped but **never checked** before a plugin
+//! ran. This module makes that claim TRUE — it is the real verification gate
+//! the plugin load path runs before instantiating any `.wasm` module.
+//!
+//! ## What is verified, in order
+//!
+//! 1. **Module hash** — SHA-256 of the actual `.wasm` bytes must equal the
+//!    manifest's `wasm_module_hash` (`sha256:<hex>`). A tampered module
+//!    (one byte changed) fails here.
+//! 2. **Ed25519 signature** — `wasm_module_sig` (`ed25519:<base64>`, 64-byte
+//!    raw signature) must verify over the **32-byte SHA-256 digest** under
+//!    the `publisher_key` (`ed25519:<base64>`, 32-byte raw verifying key).
+//! 3. **Trust policy** — the `publisher_key` must be on the configured
+//!    allowlist, unless [`PluginPolicy::AllowUnsigned`] is in force (a loud
+//!    dev escape hatch).
+//!
+//! The crypto mirrors the in-repo Ed25519 pattern from
+//! `cog-ha-matter::witness_signing` (same `ed25519-dalek` 2.x API, same
+//! deterministic-test-key convention). SHA-256 matches the `sha256:` prefix
+//! the manifest doc already declared for `wasm_module_hash`, and the
+//! `cog-ha-matter` cog manifest's `binary_sha256` hex convention.
+//!
+//! ## Secure default
+//!
+//! [`PluginPolicy::trusted`] (the production constructor) **rejects**:
+//!   * an unsigned module (no hash / sig / key),
+//!   * a signature from a key not on the allowlist,
+//!   * any hash or signature mismatch.
+//!
+//! Only [`PluginPolicy::AllowUnsigned`] loosens this, and every load it
+//! waves through emits a `warn`-level log line so it cannot pass silently.
