 ## [Unreleased]
 
+### Changed
+- **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
+- **Beyond-SOTA `v2/crates/` sweep (ADR-154–158) + full stub-implementation push — every claim MEASURED or graded.** A 5-milestone review/optimize/secure/benchmark/validate sweep, then a verified-audit-driven push to replace every production stub with real, tested logic (no labels, no placeholders). Each fix is pinned by a test that fails on the old code; every number ships with a reproduce command. Workspace: **3,122 tests / 0 failed** (`cargo test --workspace --no-default-features`), Python proof **VERDICT: PASS** (bit-exact).
+  - **ADR-154 Signal/DSP** — revived a dead ADR-134 CIR coherence gate (canonical-56 vs ht20 mismatch meant it never ran in production: 8/8 Err → 8/8 Ok); NaN-bypass + window div0 guards; PSD FFT-planner cache (**2.0–3.1×**) + honored DTW band (**2.4–4.1×**).
+  - **ADR-155 NN/Training** — unified 7 divergent PCK/OKS metric definitions into one canonical torso-normalized source (fixed two claim-inflating bugs: zero-visible PCK 1.0→0.0, OKS fake-Gold); leak-free subject-disjoint MM-Fi split + injected-leak detector; rapid_adapt replaced fake gradients with real finite-difference; proof.rs gained a min-decrease margin + committed-hash requirement; zero-copy ORT input (**1.48×**).
+  - **ADR-156 RuVector/Fusion** — closed crafted-input DoS panics (triangulation/heartbeat); honest dimensionless GDOP = √(trace(G⁻¹)) replacing an RMSE mislabel; canonical wrapped angular distance; fuse() double-clone removed (**~2.17×** marshalling). SOTA graded: SymphonyQG (CLAIMED), multi-bit RaBitQ (near-term), GraphPose-Fi (data-gated).
+  - **ADR-157 Hardware/Sensing** — `Vec::remove(0)` O(n²) sliding windows → `VecDeque`; breathing partial-weight renormalization; IIR low-sample-rate divergence clamp. Centerpiece: a MEASURED **negative-results** audit showing the layer (802.11bf model, parsers, calibration) was already hardened — cited file:line, NO-ACTION.
+  - **ADR-158 MAT/world-model** — **unified two divergent triage engines** (the confidence-gated result was computed then discarded; gate==record now); **killed survivor count-inflation** (real RSSI localization + vitals-signature dedup, MEASURED 3→1); real ESP32/UDP/PCAP CSI ingest with honest typed `HardwareUnavailable`/`UnsupportedAdapter` errors for hardware-gated adapters (Intel5300/Atheros/PicoScenes — never fabricated CSI); real parabolic peak interpolation; real GDOP.
+  - **Soul Signature §3.6 matcher made real (`wifi-densepose-bfld`, issue #1021).** An external audit correctly found person-identification was spec-only behind a no-op `NullOracle`. Now a real per-channel weighted-cosine matcher + `EnrolledMatcher: SoulMatchOracle` (364 tests). MEASURED: same-person 1.0000 vs cross-person 0.8088; and the audit's own claim proven — on WiFi-only cardiac+respiratory channels alone two people are **not separable** (gap 0.0005). Named identity is honestly **data-gated** on the AETHER/body-resonance channel being fed by a real enrollment; no working-named-identity claim is made.
+  - **OccWorld real forward pass** — replaced `Tensor::randn` encoder/decoder stubs (which emitted trajectory priors from pure noise) with a real deterministic conv VQ-VAE forward pass (input-dependent, proven by tests that fail on the old randn) + a `weights_trained` honesty flag (false until a real checkpoint loads); pointcloud `to_gaussian_splats` 9→2 passes (**1.24×** MEASURED).
+  - **Native multi-BSSID `wlanapi.dll` FFI** (`wifi-densepose-wifiscan`) — real `WlanOpenHandle`/`WlanEnumInterfaces`/`WlanGetNetworkBssList`, **MEASURED 9.74 Hz** on Windows (vs netsh ~2 Hz; no fabricated "10×"), typed `Unsupported` off-Windows. Real Matter 1.3 manual-pairing-code field-packing (canonical 34970112332, lossless decode) replacing a lossy-modulo placeholder.
+  - **HOMECORE assistant** — real `LocalRunner` response path, real semantic intent recognizer (exact in-memory cosine k-NN; MEASURED 0.855 match / 0.106 no-match), real SQL state text-search — three always-empty stubs removed.
+- **ADR-152 WiFi-Pose SOTA 2026 intake — verified external benchmark + four Rust integrations.** A 22-source adversarially-verified survey of the 2025–2026 WiFi-sensing SOTA, with every adopted number reproduced or graded before integration:
+  - **WiFlow-STD (DY2434) reproduction (`benchmarks/wiflow-std/`)** — the external "97.25% PCK@20, 2.23M params" claim audited end-to-end: the **shipped checkpoint is REFUTED** (0.08% PCK@20 — wrong keypoint normalization, predates the published code), the released code does not run as published (6 documented defects, incl. an import that fails and an unreachable test phase), and the released dataset's final 13 files are corrupted (9,072 windows of NaN + float32-max garbage that NaN-poisons fp16 BatchNorm training). After repairing both, retraining with upstream defaults on an RTX 5080 reproduced **96.09% PCK@20 (full test) / 96.61% (corruption-free)** — claims graded MEASURED-EQUIVALENT; params (2,225,042) and FLOPs (~0.055 G) verified exactly. Full forensics in `benchmarks/wiflow-std/RESULTS.md`.
+  - **`GeometryEmbedding` (ADR-152 §2.1.2, `wifi-densepose-calibration`)** — 32-slot permutation-invariant, NaN-proof featurization of the §2.1.1 `NodeGeometry` records (centroid/spread, measured-first pairwise distances, circular azimuth stats, covariance-eigenvalue geometric diversity, per-node flags), schema-versioned for the ADR-151 P6 LoRA heads; derived `SpecialistBank::geometry_embedding()` accessor. The PerceptAlign "coordinate overfitting" defense, transplanted to per-room banks.
+  - **MAE pretraining recipe (ADR-152 §2.3, `wifi-densepose-train/src/mae.rs`)** — `MaePretrainConfig` pinning the UNSW-measured recipe (80% masking, (30,3) patches) with pure-Rust patchify/random-mask (exact counts, seed-deterministic, error-not-truncate divisibility, NaN rejection), property-tested; the consumption seam for the future ADR-150 ViT-Small encoder.
+  - **`WiFlowStdModel` Rust port (`wifi-densepose-train/src/wiflow_std/`)** — tch-gated idiomatic port of the verified spatio-temporal-decoupled architecture (grouped causal TCN → asymmetric conv stack → dual axial attention); ungated param formula asserted equal to the reference 2,225,042; 15/17-keypoint variants share weights (enables the ADR-152 §2.2(b) ESP32 fine-tune).
+  - **RuVector vendor sync + §2.6 opportunity survey** — vendor at `a083bd77f`; graded ADOPT/EVALUATE/WATCH table; crates.io bumps applied (mincut/solver 2.0.6, attention 2.1.0, gnn 2.2.0; RUSTSEC #504 audit: no pinned crate affected); top WATCH: unpublished `ruvector-graph-condense` differentiable min-cut for trainable subcarrier grouping.
+- **ADR-153 IEEE 802.11bf-2025 forward-compatibility protocol model (`wifi-densepose-hardware/src/ieee80211bf/`)** — typed WLAN-sensing procedures (measurement setup/instance/report, SBP, termination) with `SpecProfile` version gates, `SensingCapabilities` negotiation, and **required** `ConsentMode` governance metadata on every setup; deterministic session FSM with rejection/timeout paths; `SensingTransport` seam with `SimTransport` and an `OpportunisticCsiBridge` mapping live ESP32 CSI batches into standardized report shape (a future chipset adapter replaces the bridge without touching RuvSense consumers). Not a certified implementation — simulation-tested protocol surface; OTA binding lands when silicon does. 19 acceptance tests.
+- **Dynamic min-cut mesh partition guard in the streaming engine (`mesh_guard`).** Maintains a `ruvector-mincut` exact min-cut over the live mesh coupling graph (nodes = sensing nodes, coupling = product of fusion attention weights), surfacing per cycle: the global **cut value** (how close the array is to splitting — a structural measure per-node heuristics miss), the **weak side** (which specific nodes would partition: failure/jamming triage feeding ADR-032 posture), and an **at-risk flag** that counts as a structural event for the drift→recalibration advisor. Surfaced as `TrustedOutput::mesh`. **Measured cost policy** (criterion, 12-node mesh): weights are quantized (1/64; a *nonzero* coupling below one quantum saturates to quantum 1 so quantization never erases a live coupling — without the floor, balanced meshes of ≥ 65 nodes had every ~1/n coupling erased and sat permanently "at risk") and updates change-gated, so the steady-state cycle does zero graph work (~7.3 µs, ~23× cheaper than building); on any real change a full exact rebuild (~171 µs) is used because one `DynamicMinCut` delete+insert measured ~240 µs — the incremental machinery's overhead targets much larger graphs, so rebuild-on-change is the measured optimum at mesh scale (one-edge case −28% after the policy switch). Degenerate cases fail toward risk: a node with zero coupling is reported as already partitioned (cut 0). 9 mesh-guard tests + an engine-level wiring test; full `process_cycle` with the guard: ~33 µs for 4 nodes (50 ms budget).
+- **Opt-in FFT operator for the CIR ISTA solver (8–14× measured).** Φ is a sub-DFT, so each ISTA mat-vec can run as one length-G FFT (O(G log G)) instead of a dense O(K·G) product. New `CirConfig::fft_operator` (default **false** — the dense path stays the bit-exact witness default; the FFT evaluates the same sums in a different order, so enabling it shifts float results and requires regenerating any pinned witness). `FftOperator` (rustfft, planned once at construction, scratch reused across the ISTA loop) dispatches inside `ista_solve`; warm-start/Lipschitz stay dense at construction. Measured (criterion, same run): ht20 2.22 ms → 265 µs (**8.4×**), ht40 10.26 ms → 717 µs (**14.3×**); the real HE40 grid (K=484, G=1452) scales further. 3 new tests: FFT↔dense matvec equivalence to float tolerance (ht20 + he40 grids), end-to-end dominant-tap agreement on a single-path frame, and all default configs keep FFT off. New `cir_estimate_fft` bench group.
+- **Per-room adapter provenance + drift→recalibration advisor in the streaming engine.** Closes the trust-chain gap where an ~11 KB per-room LoRA adapter (ADR-150 §3.4) could silently change inference without the witness noticing. `StreamingEngine::set_room_adapter(AdapterInfo)` pins the adapter's content-derived id into provenance `model_version` (`rfenc-v1+adapter:<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.*
+- **RuView beyond-SOTA research series** (`docs/research/ruview-beyond-sota/`, 6 docs) — research-swarm output defining the beyond-SOTA bar and the path to it: system capability audit (role→crate maturity matrix, gap analysis, risk register), web-verified 2026 SOTA landscape per capability axis (incl. ratified IEEE 802.11bf-2025), 8-pillar target architecture on the ADR-136 contract spine (no rewrite), 6-layer benchmark/validation methodology (all 15 criterion bench targets inventoried; ADR-149 statistical protocol), and a determinism-safe optimization roadmap. Includes session validation evidence: 2,797 workspace tests / 0 failed, Python proof PASS (bit-exact), paired pre/post criterion runs.
+
+### Performance
+- **CIR estimator warm-start precompute** — the diagonal Tikhonov preconditioner `diag(Φ^H Φ)+λI` and its CSR matrix were rebuilt every frame although they depend only on Φ and λ (fixed at `CirEstimator::new`); now precomputed at construction (`ruvsense/cir.rs`). Bit-identical floats (summation order unchanged, witness chain unaffected). Measured: `cir_estimate/he40` −3.9% (p<0.01), multiband groups −1.2/−1.4%; smaller configs within container noise.
+- **RF tomography solver hoisting** — ISTA gradient buffer no longer allocated inside the 100-iteration loop, and the Frobenius Lipschitz bound moved from per-`reconstruct` to construction (`ruvsense/tomography.rs`). Bit-identical results.
+
+### Added
+- **Falsifiable occupancy benchmark (`wifi-densepose-train::occupancy_bench`).** Makes the presence/person-count "beyond SOTA" claim falsifiable in code instead of aspirational (the unfalsifiability gap from the beyond-SOTA system review). Grades predictions vs ground truth and gates a SOTA claim behind one `claim_allowed` invariant requiring all of: `DataProvenance::Measured` (synthetic/mock is scorable but **never claimable** — anti-mock-contamination per the CLAUDE.md Kconfig-bug lesson), a leak-free `EvalSplit` (refuses any split where a subject *or* environment id appears in both train and test — subject leakage / per-environment overfitting), `n_test ≥ min`, a **non-degenerate test set** (both truth classes represented: present-rate ≥ `min_positive_rate` and ≥ 1 absent sample — an all-absent set plus an always-absent predictor cannot release a claim; vacuous F1 scores 0.0, never 1.0), presence-F1 **bootstrap-CI lower bound** (deterministic seeded splitmix64) clearing the threshold, and count MAE within threshold. The claim string is unreadable except through the gate (`NO_CLAIM` otherwise). What remains is data, not method: a frozen, SHA-pinned, subject/environment-disjoint measured replay set turns the claim into a passing/failing test. 12 tests cover each refusal path, including the point-above/CI-below case (claim withheld on the CI lower bound even when the point estimate clears the threshold).
+- **Live trust path: sensing-server routes real frames through the governed `StreamingEngine` (parallel governed path with partial output gating).** Previously the live server ran only the *bare* `MultistaticFuser` (fused amplitudes, no trust control plane), while the privacy/provenance/witness engine (ADR-135..146) ran only on synthetic in-test frames — the gap called out in ADR-136 §8 and the beyond-SOTA system review. New `engine_bridge` module drives `StreamingEngine::process_cycle` from the server's live `NodeState` map (reusing the existing `NodeState → MultiBandCsiFrame` conversion), lazily wiring each node as a WorldGraph sensor and bounding belief growth via the retention cap; every *governed belief* carries evidence + model + calibration + privacy decision and a deterministic witness. **Honest scope:** the engine runs alongside (not instead of) the bare fusion path that feeds the live `SensingUpdate`. What its decision gates on the wire today: a cycle emitted at class `Restricted` (base mode or contradiction/mesh-risk demotion) suppresses the per-node raw amplitude vectors from the live publish — the same field mapping `wifi-densepose-bfld`'s privacy gate applies at `Restricted`; gating the remaining derived outputs (person count, classification, signal field) is tracked as a follow-up. Trust state is no longer write-only: the latest witness, effective privacy class, demotion flag, recalibration recommendation, and an engine-error counter are readable on `GET /api/v1/status`, and engine errors are counted + rate-limit logged instead of silently swallowed (`EngineBridge::observe_cycle`). Adds `wifi-densepose-engine/-worldgraph/-bfld/-geo` deps. Bridge tests cover witnessed belief with provenance, determinism, idempotent node registration, retention bound, privacy-mode propagation, trust-state recording, the error-counter path, and Restricted-class raw-output suppression.
+
+### Fixed
+- **`wifi-densepose-mat` standalone `--no-default-features` build (101 errors → 0).** `pub mod api` was unconditional while its only dependency, serde, is optional behind the `api` feature — so any build without default features failed with unresolved serde imports (masked in `--workspace` runs by feature unification). The `api` module and its `create_router`/`AppState` re-export are now `#[cfg(feature = "api")]`-gated (with docsrs annotations). All feature combos compile: bare `--no-default-features`, `--no-default-features --features api`, and full default (177 tests pass).
+- **WorldGraph no longer grows unboundedly under the live loop.** `StreamingEngine::process_cycle` appended one `SemanticState` belief per cycle with no eviction — ~1.7M nodes/day at 20 Hz (identified in `docs/research/ruview-beyond-sota/04-optimization-roadmap.md`). Added `WorldGraph::prune_semantic_states(max)` — deterministic eviction of the oldest beliefs by `(valid_from_unix_ms, id)`, structural nodes (rooms/zones/sensors/anchors/tracks/events) never eligible — and wired it into the engine after each belief append (`StreamingEngine::DEFAULT_SEMANTIC_RETENTION` = 7,200 ≈ 6 min at 20 Hz; tunable via `set_semantic_retention`). The WorldGraph holds *current* beliefs; durable history is the recorder's job, so no audit data is lost. 3 new tests (bounded growth end-to-end, oldest-only eviction, deterministic tie-break).
+- **ESP32 edge heart rate no longer stuck at ~45 BPM / dropping wildly — #987.** The on-device HR estimator (`edge_processing.c`, `0xC5110002`) reported ~45 BPM regardless of true heart rate (Apple-Watch ground truth 87 BPM read as ~45) and swung frame-to-frame. Two root causes: (1) a hardcoded `sample_rate = 10.0f` that became wrong after #985's self-ping raised the CSI callback rate to a variable ~13–19 Hz — BPM scales as `assumed/actual × true`, so 87 read ~45 and the reading swung as CSI yield fluctuated; (2) the zero-crossing estimator locked onto a breathing harmonic (a 0.25 Hz breathing fundamental puts its 3rd harmonic at ~0.74 Hz ≈ 44 BPM inside the HR band). Fix: measure the real sample rate from inter-frame timestamps (used for BPM conversion + biquad re-tuning on >15% drift); replace the HR zero-crossing with an autocorrelation estimator that rejects breathing harmonics (driven by a robust autocorr breathing period); median-13 smooth the output. Hardware A/B (fixed vs unmodified control board, both `edge_tier=2`): control pegged 40–49 BPM; fixed reaches the true 88–91 BPM (vs 87 GT) and holds a stable physiological value (spread 59→0 for a steady subject). Known limitation: heavy subject motion still degrades the estimate (motion gating is a follow-up).
+- **Person count no longer leaks up to 10 in heuristic mode — addresses #894.** `field_bridge::occupancy_or_fallback` returned the eigenvalue-based `FieldModel::estimate_occupancy` count **unbounded** (its internal ceiling is 10), while the sibling estimators on the same single-link data — the perturbation-energy fallback right below it and `score_to_person_count` — both cap at 3 ("1-3 for single ESP32"). On noisy / under-calibrated CSI the eigenvalue count inflated, producing the "10 persons reported when 1 present" symptom (seen when `--model` fails to load and the server runs on heuristics). Bounded the eigenvalue path to the shared `MAX_SINGLE_LINK_OCCUPANCY` (3) so every estimator on one link agrees; genuine higher counts come from the multistatic fusion path, not a single-link covariance estimate.
+- **MQTT multi-node deployments now create one Home-Assistant device per node — closes #898.** After the #872 MQTT wiring landed, the JSON→`VitalsSnapshot` bridge hard-coded a single `node_id` (the MQTT client id) and the publisher used a single `OwnedDiscoveryBuilder`, so every physical node collapsed into one device (`identifiers:["wifi_densepose_wifi-densepose-1"]`), contradicting the "one device per node" docs. The bridge now emits one snapshot per node in the sensing update's `nodes[]` (each with its own `node_id` + RSSI, falling back to a single aggregate snapshot for wifi/simulate sources), and the publisher derives a per-node builder (`OwnedDiscoveryBuilder::for_node`) that publishes discovery + availability lazily on first sight of each `node_id` and routes state to per-node topics — yielding N distinct HA devices with per-node availability/LWT. Unit-tested (distinct nodes → distinct `wifi_densepose_<node>` identifiers); 71 MQTT tests pass.
+- **Person count no longer pinned to 1 — addresses #803.** The aggregate occupancy reported by the sensing server was derived from `smoothed_person_score`, an EMA-smoothed *activity* score (amplitude variance / motion / spectral energy). That score saturates near a single occupant — one moving person maxes it out — so it cannot discriminate occupancy *count* and stayed clamped at 1 across S3/C6 and the Python/Docker/Rust servers. Meanwhile the count-aware per-node estimates the ESP32 paths already compute (firmware `n_persons`, and the DynamicMinCut `corr_persons`) were stashed in `NodeState::prev_person_count` and then **discarded** by the aggregator (same dead-wiring class as #872). The aggregator now takes `max(activity_count, node_max)` via a unit-tested `aggregate_person_count` helper, so a node positively estimating 2–3 occupants is surfaced instead of overwritten. The fix can only ever *raise* the count when a node reports more people, so the single-occupant case is provably never inflated (regression-guarded by test). **Second half:** the pure-CSI per-node path itself clamped its own estimate — the DynamicMinCut occupancy (`estimate_persons_from_correlation`, 0–3) was mapped to a score via `corr_persons / 3.0`, putting 2 people at 0.667, *just under* the 0.70 up-threshold of `score_to_person_count`, so the per-node count never climbed past 1 (so `node_max` was also stuck at 1 for CSI-only nodes). Replaced it with a threshold-aligned `corr_persons_to_score` mapping (1→0.40, 2→0.74, 3→0.96) whose steady state round-trips back to the same count through the EMA + hysteresis, while still gating transient noise. A convergence test replays the exact EMA loop to prove min-cut=2 now reports 2 (and documents that the old `/3.0` mapping reported 1). Full multi-person accuracy still depends on the underlying estimator quality; this removes the two server-side clamps that masked it. 586 sensing-server tests pass.
+- **MQTT publisher now actually runs (`--mqtt`) — closes #872.** The `--mqtt*` flags were defined only in `cli::Args` (dead code, referenced nowhere) while the binary parses a *separate* `main::Args` with no mqtt fields, and `main.rs` never started the `mqtt::` publisher — so MQTT/Home-Assistant integration was completely unwired (`--mqtt` errored as an unexpected argument, and even with the Docker image's `--features mqtt` build the publisher never ran). Earlier attempts chased a Docker *rebuild*; the real cause was disconnected *code*. Extracted the flags into a shared `cli::MqttArgs` (`#[command(flatten)]` into both structs), spawn the publisher on `--mqtt`, and bridge the JSON sensing broadcast into the typed `VitalsSnapshot` stream with a defensive `serde_json::Value` mapping. Verified end-to-end against `mosquitto`: 20 HA auto-discovery entities + live state (presence/person-count/…). 577 (default) / 580 (`--features mqtt`) tests pass.
+- **Mass Casualty triage never reports a survivor with a heartbeat as Deceased (safety) — PR #926.** Both triage paths in `wifi-densepose-mat` — `TriageCalculator::calculate` (`combine_assessments(Absent, None) ⇒ Deceased`) and the detection path `EnsembleClassifier::determine_triage` (`!has_breathing && !has_movement ⇒ Deceased`) — ignored the `heartbeat` field. A survivor with a detectable **pulse** but no sensed breathing/movement (respiratory arrest — the most time-critical *savable* state, Immediate/Red) was therefore reported **Deceased (Black)** and deprioritized for rescue. The domain path was in fact only reachable *because* a heartbeat made `has_vitals()` true, so every "Deceased" was a live person. Both paths now escalate to **Immediate** when a heartbeat is present; total absence of breathing, movement *and* heartbeat is unchanged (domain → `Unknown`, ensemble → `Deceased`). 2 safety regression tests; full MAT suite (177) green.
+- **Per-node Home-Assistant devices now report each node's *own* presence/motion — PR #918.** After the one-device-per-node fan-out landed, the MQTT bridge still applied the *room-level aggregate* `classification` to every node, so in a multi-node deployment a node watching an empty corner inherited another node's "present" (and `motion_level: "absent"` was mis-mapped to full motion). Each node in the broadcast `nodes[]` already carries its own `classification`; the bridge now reads it per node (extracted into a testable `vitals_snapshots_from_sensing_json`), keeping vitals + person count room-level. 4 unit tests.
+- **`--model` gives an actionable diagnostic instead of a cryptic magic error — PR #919 (refs #894).** Passing a HuggingFace `ruvnet/wifi-densepose-pretrained` file (`model.safetensors` / `model-q4.bin` / `model.rvf.jsonl`) to `--model` produced `invalid magic at offset 0: … got 0x77455735`, then a silent fall back to heuristics. The load-failure path now detects the format (safetensors / quantized blob / JSONL manifest) and explains that those files are a different format **and** encoder architecture than the RVF binary container the progressive loader expects, pointing to #894. Pure `diagnose_model_load_error` + 4 tests.
+- **`--export-rvf` no longer silently produces a placeholder model — PR #920.** The `--export-rvf` handler ran *before* `--train`/`--pretrain` and unconditionally wrote placeholder sine-wave weights, so the documented `--train … --export-rvf <path>` workflow short-circuited to a fake model and never trained (while printing "exported successfully"). It now emits the placeholder **container-format demo** only standalone (with a clear warning), and falls through to real training when `--train`/`--pretrain` is set; docs point to `--save-rvf` for the real model. 3 guard tests.

+- **ADR-151 per-room calibration & specialist training — full `baseline → enroll → extract → train` pipeline (new `wifi-densepose-calibration` crate).** "Teach the room before you teach the model": a local-first pipeline that turns a few minutes of clean human anchors — layered on the ADR-135 empty-room baseline — into a versioned bank of small, room-calibrated specialists for **presence, posture, breathing, heartbeat, restlessness, and anomaly**. Stages: guided enrollment with an adaptive quality gate (event-sourced `EnrollmentSession`, re-prompts bad anchors); feature extraction (autocorrelation periodicity in breathing/HR bands + variance/motion); six small specialists (learned threshold / nearest-prototype / band-limited periodicity / novelty); a `SpecialistBank` with baseline-drift **STALE** invalidation; and a `MixtureOfSpecialists` runtime with presence short-circuit + anomaly veto + confidence gating. Specialists are statistical heads today (runnable + hardware-validated); the frozen ADR-150 HF RF Foundation Encoder backbone is the documented upgrade path.
+  - **CLI:** `enroll` / `train-room` / `room-status` / `room-watch`, plus the Stage-1 `calibrate-serve` HTTP API (CORS-enabled: `POST /start`, `GET /status`, `POST /stop`, `GET /result`, `GET /baselines`, `GET /health`) and a firewall-free `scripts/csi-udp-relay.py` for local Windows ESP32 testing without admin.
+  - **Multistatic fusion (ADR-029):** `MultiNodeMixture` fuses several co-located nodes (each with its own room-calibrated bank) into one room state — presence OR'd across nodes, posture/breathing/heartbeat from the highest-confidence node, a single implausible node vetoes the room's vitals. Driven via `room-watch --node-bank N:path` (repeatable), which groups live frames by `node_id` and fuses. Same-room only; cross-room is federation (ADR-105).
+  - **Validated on live ESP32-S3 (COM8, `edge_tier=0` raw CSI):** baseline capture (120 frames → 52-subcarrier baseline); the real parser → feature-extraction → mixture runtime detecting breathing (~16–31 BPM); and the multistatic ingest grouping/fusing by node-id end-to-end. Full multi-anchor enrollment accuracy requires the operator to perform the poses; true 2-node fusion + phase-based breathing + RVF/HNSW storage are noted follow-ups. 54 tests pass (35 calibration + 19 CLI).
+- **WiFi-CSI pose: efficiency frontier + per-room calibration service** (ADR-150 §3.2–3.6). Two beyond-SOTA results on the MM-Fi benchmark, plus the deployment mechanism that resolves real-world generalization:
+  - **Efficiency frontier** — a **75 K-param model beats published SOTA** (74.3% vs MultiFormer 72.25% torso-PCK@20); every config from `micro` up is Pareto-dominant (smaller *and* more accurate than prior work). Shipped a deployable **int4 edge model (~20 KB, verified 74.08%, 0.135 ms single-thread CPU)** — published at [`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose). See [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](docs/benchmarks/wifi-pose-efficiency-frontier.md).
+  - **Generalization solved by few-shot calibration** — zero-shot cross-subject (~64%) and cross-environment (~10%) are *not* closeable by algorithms (CORAL, DANN, instance-norm, contrastive foundation-pretraining all tested, all failed) or by more training subjects (saturates ~64%). But **~100–200 labeled in-room samples recover SOTA-level pose**: cross-subject 64→76%, **cross-environment 10→73% (60% from just 5 samples)** — deployable as a **~11 KB per-room LoRA adapter** on a frozen shared base. Full empirical chain in ADR-150 §3.2–3.6.
+  - **Calibration service (complete, both model paths, cross-language verified)** — `aether-arena/calibration/`: `calibrate.py` (transformer model, `.npz` adapter) + `infer.py` (verified 3.09%→74.29% on an unseen MM-Fi room), **and `cog_calibrate.py`** which fits a `fc1.a/fc1.b/fc2.a/fc2.b` **safetensors** adapter for the deployed cog conv+MLP model (`pose_v1.safetensors`). Consumed by the Rust product engine: `InferenceEngine::with_adapter()` + `cog-pose-estimation run --config <cfg> --adapter <room.safetensors>`. Self-contained regression tests for both Python producers (`test_calibration.py`, `test_cog_calibration.py`) **plus a cross-language Rust integration test** that loads a real `cog_calibrate.py`-generated adapter fixture and asserts it activates + changes engine output. All green.
+- **Windows workspace build + test now green** (cross-platform fixes). `wifi-densepose-worldmodel` imported `tokio::net::UnixStream` unconditionally, so `cargo build/test --workspace` failed to compile on Windows (E0432) — now the OccWorld Unix-socket bridge is `#[cfg(unix)]`-gated with a clear non-unix fallback. And `wifi-densepose-bfld`'s `readme_quickstart_uses_canonical_public_api` test checked a multi-line `pipeline\n    .process` needle that never matched on a CRLF checkout — now normalizes line endings. Result: **2,682 workspace tests pass / 0 fail on Windows** (the pre-merge gate was previously unrunnable there).
+- **`ruview-swarm` crate (ADR-148)** — drone swarm control system with hierarchical-mesh topology, Raft consensus, MAPPO multi-agent reinforcement learning, and CSI sensing integration. 14 modules: topology (Raft/Gossip/Mesh), formation control (virtual-structure/leader-follower/Reynolds flocking), RRT-APF path planning, auction+FNN task allocation, MARL actor + PPO training loop, security (MAVLink v2 HMAC-SHA256 signing, UWB anti-spoofing, geofencing, Remote ID, FHSS anti-jamming), 10-state fail-safe machine, and SwarmOrchestrator. ITAR-gated coordination features (USML Category VIII(h)(12)) behind `itar-unrestricted` feature.
+- **Ruflo integration for `ruview-swarm`** — feature-gated (`ruflo`) AI-agent capability layer connecting to the claude-flow daemon: AgentDB mission memory (`memory_store`/`memory_search`), HNSW pattern learning (`agentdb_pattern-store`/`-search`), AIDefence MAVLink message scanning, and SONA intelligence trajectory hooks. `RufloBackend` trait with `HttpRufloBackend` (JSON-RPC 2.0) and `MockRufloBackend` implementations.

 ### Security
 - **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk <hex>` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible.
+- **Bearer-token auth accepts the scheme case-insensitively (RFC 6750) — PR #929.** `require_bearer` parsed the `Authorization` header with a case-sensitive `strip_prefix("Bearer ")`, so a *correct* `RUVIEW_API_TOKEN` sent as `Authorization: bearer <token>` (or `BEARER`, or with extra whitespace) was rejected with a confusing 401 — needless friction when enabling auth. The scheme is now matched with `eq_ignore_ascii_case` (per RFC 6750 §2.1 / RFC 7235 §2.1); the token compare is unchanged — still exact and constant-time (`ct_eq`) — so a wrong token or a non-Bearer scheme (`Basic …`) still returns 401. Audited the surrounding code while here: `ct_eq` correctly rejects length mismatch (no prefix-auth bypass) and the middleware fails closed. New `accepts_case_insensitive_bearer_scheme` test.

+# PROOF — reproduce every claim, or find the one we can't yet
+
+This project (RuView / wifi-densepose) has been publicly called "AI slop" and
+"fake." This document is the answer: **a skeptic can clone the repo, run one
+script, and have every headline claim either verified on their own machine or
+shown — explicitly — as "CLAIMED, not yet reproduced (here's exactly what it
+needs)."** Nothing below is asserted without a command you can run.
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView
+bash scripts/prove.sh          # core gate + the anti-slop assertion tests
+bash scripts/prove.sh --full   # also attempt the feature-gated subset
+```
+
+`prove.sh` exits 0 only if every **non-gated** claim passes. Gated claims never
+fail the run; they print the prerequisite (a GPU, a dataset, real hardware, a

+- **DATA-GATED / HARDWARE-GATED** — the *code path* is real and tested, but the

+| **Named person-identity from WiFi** | **NOT achieved, and measured why.** The §3.6 matcher is real, but identity does not lock on WiFi-only channels (gap 0.0005). DATA-GATED on a real enrollment feeding the AETHER/body-resonance channel — never done. No named-identity claim is made. |
+| WiFlow-STD ~96% PCK@20 | **CLAIMED-reproduced** on our RTX 5080 (`benchmarks/wiflow-std/RESULTS.md`); HARDWARE-GATED for you (needs an NVIDIA GPU + the MM-Fi dataset). The upstream *shipped checkpoint* was **REFUTED** (0.08% PCK) — we publish that. |
+| OccWorld trajectory accuracy | DATA-GATED on a trained checkpoint; `predict()` carries `weights_trained=false` until one is loaded — never silently faked. |
+| Edge-skill detection accuracy (seizure, weapon, affect, …) | UNVALIDATED — every such module is now disclaimer-gated as experimental/research; the DSP is real, the accuracy is not claimed. |
+| 802.11bf-2025 OTA conformance | No commodity silicon ships a conformant interface as of 2026; ours is a simulation-tested forward-compat protocol model, not a certified implementation. |

+includes published **retractions** (the 92.9% PCK retraction; the WiFlow-STD

+# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
+
+> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
+
+AetherArena is a **standalone, project-agnostic benchmark** for camera-free **spatial intelligence** — pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over time, mmWave / UWB / radar / lidar / multimodal). It is **not** a single-vendor leaderboard: any team, framework, or sensing modality can enter, and every entrant — including the RuView baseline that donated the seed scorer — is scored by the identical, open, pinned harness.
+
+Specified in [ADR-149](../docs/adr/ADR-149-public-community-leaderboard-huggingface.md) (Accepted).
+
+Canonical home: **`ruvnet/aether-arena`** + a Hugging Face Space (deploy pending — see `STATUS`).
+
+---
+
+## Why
+
+WiFi/RF spatial sensing has no shared yardstick — papers self-report against inconsistent splits and metrics, with **no accounting for latency, reproducibility, or privacy leakage**. AA fixes the *measurement*, not just the models: a single deterministic scorer, a private held-out split nobody can train on, and a signed result ledger that can't be silently edited.
+
+## What gets measured (v0)
+
+| Category | Metric | Status |
+|----------|--------|--------|
+| **Pose** | PCK@0.2 (all / torso), OKS | Ranked |
+| **Presence** | accuracy, FP/FN | Ranked |
+| **Edge latency** | p50 / p95 / p99 ms | Ranked |
+| **Determinism** | proof-hash pass/fail | Ranked (gate) |
+| Tracking (MOTA) | — | activates when multi-person clips land |
+| Vitals (BPM err) | — | activates when paired vitals ground truth lands |
+| **Privacy leakage** | membership-inference ∈ [0,1] | **gated — not ranked** until the attacker ships |
+| Cross-room | degradation ratio | coming soon |
+
+The headline rank is the **category metric**; an optional `arena_score = quality × latency_factor × privacy_factor × determinism_gate` is exposed alongside (never instead) so accuracy can't win at any cost. See ADR-149 §2.5.
+
+## How scoring works
+
+The scorer is RuView's **already-published** `wifi-densepose-train` acceptance harness (`ruview_metrics` + ADR-145 `ablation`), run in a pinned sandbox. **You submit a model, not predictions** — predictions on data you hold prove nothing. Your model is scored against a **private** MM-Fi held-out split (CC BY-NC 4.0; Wi-Pose excluded for redistribution reasons), and one **signed, append-only** row is written to the results ledger with a determinism proof hash.
+
+Submission lifecycle: `submitted → validated → quarantined → smoke_scored → full_scored → published` (or `rejected` with a reason). The model only ever runs inside a no-network, read-only-FS sandbox.
+
+## Submit (when the Space is live)
+
+1. Write a manifest: [`schema/aa-submission.toml`](schema/aa-submission.toml).
+2. Push your model artifact (`.safetensors` / `.rvf` / LoRA adapter) + manifest to the Space.
+3. Watch it move through the lifecycle; your signed row appears on the board.
+
+## Verify it's fair (you don't have to trust us)
+
+See [`VERIFY.md`](VERIFY.md) — run the **open scorer** locally on the **public smoke split**, reproduce the determinism hash, and confirm RuView's own entries were scored by the identical path. That five-step check is the launch gate (ADR-149 §7).
+
+## Neutrality
+
+AA is a neutral commons. The scorer is open and versioned; any metric change is a public `harness_version` bump that **re-scores all entries**. RuView donated the seed harness and enters as one baseline — it gets no special treatment (ADR-149 §2.8).

+Remaining = data + hardening, not infra: private MM-Fi held-out split (M5), sandboxed scorer container (M6), privacy-leakage attacker (gated category), and **model SOTA** (separate ML effort, blocked on ADR-079 — explicitly not an infra exit).
+
+## Benchmark-first posture (per user direction)
+- **No placeholder numbers on the board.** The ledger seeds to genesis only; every result is a real scoring-pipeline witness. RuView gets no seeded baseline.
+- **Witness chain** = `inputs_sha256` (binds witness to exact inputs) + `proof_sha256` (cross-platform-stable score hash) + the append-only hash-chained ledger. Repeatability analysis (`--repeat N`) proves the proof hash is identical across runs.
+
+## Blockers / decisions needed
+- **HF deploy (M6)** — token is in GCP Secret Manager (`HUGGINGFACE_API_KEY`); creating the public `ruvnet/aether-arena` Space still wants explicit go.
+- **MM-Fi is CC BY-NC** → AA must stay non-commercial / legally distinct from the commercial RuView product.
+- **Private MM-Fi split (M5)** — needs the dataset pulled + a held-out split assembled before real public scoring replaces the smoke fixture.

+# Verifying AetherArena (you don't have to trust us)
+
+AA's credibility rests on a stranger being able to reproduce a score and see that the rules are fair. This is the **launch gate** (ADR-149 §7): v0 does not ship until all five checks below pass for someone with no insider access.
+
+> **Wider context:** this page covers the *leaderboard scorer*. For the whole-platform answer to
+> "is this real / does it actually work?" — including the deterministic pipeline proof, the
+> published models + public-benchmark numbers, and the built-in-public development trail — see
+> [`docs/proof-of-capabilities.md`](../docs/proof-of-capabilities.md).
+
+## The open scorer
+
+The scoring engine is a pure-Rust, GPU-free binary: `aa_score_runner` in `wifi-densepose-train`. It runs the real `ruview_metrics` pose-acceptance harness on a fixed fixture and emits a cross-platform-stable SHA-256 **determinism proof**.
+
+### Reproduce the determinism hash locally
+
+```bash
+cd v2
+# Verify the committed expected hash still matches (this is the CI gate):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# → prints the witness (inputs_sha256 + proof_sha256) and "VERDICT: PASS"
+
+# See the witness row as JSON:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --json
+```
+
+### Witness chain — proof + repeatability analysis
+
+Every score is a **witness**: `inputs_sha256` (binds it to the exact inputs scored)
++ `proof_sha256` (cross-platform-stable hash of the quantised score) + `harness_version`.
+Witnesses are recorded in an **append-only, hash-chained ledger** (each row references
+the previous row's hash), so a silent edit to any past row breaks the chain.
+
+```bash
+# Repeatability: run the scorer K times, confirm ONE identical proof hash:
+cd v2
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# → {"repeatability":{"runs":16,"unique_proof_hashes":1,"repeatable":true,...}}
+
+# Real model scoring (score predictions against an eval split):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- \
+  --split ../aether-arena/fixtures/smoke_split.json \
+  --pred  ../aether-arena/fixtures/smoke_pred.json --json
+
+# Verify the witness ledger chain is intact (tamper-evident):
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+# → "OK: N rows, chain intact"   (edit any row and it reports the broken link)
+```
+
+The expected hash is committed at [`fixtures/expected_score.sha256`](fixtures/expected_score.sha256). Same harness version + same fixture → same hash on glibc / MSVC / Apple. If your local run prints `VERDICT: PASS`, you have reproduced the scorer.
+
+### What happens if the scoring maths changes
+
+Any edit to `ruview_metrics.rs`, `ablation.rs`, or `aa_score_runner.rs` moves the hash and **fails the CI gate** (`.github/workflows/aether-arena-harness.yml`) until the maintainer regenerates and reviews:
+
+```bash
+cargo run -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --generate-hash \
+  > aether-arena/fixtures/expected_score.sha256
+```
+
+So a scorer change is always a reviewed, public diff — never silent. That's `harness_version` pinning + `determinism_gate` in action (ADR-149 §2.4–§2.5).
+
+## The five-step acceptance test (v0 launch gate)
+
+A stranger must be able to:
+
+1. **Submit** a model (artifact + `schema/aa-submission.toml`) with no insider help.
+2. **Get a deterministic score** — same model + same `harness_version` → same numbers.
+3. **See the signed row** appended to the public results ledger.
+4. **Rerun the scorer locally** on the public smoke split and reproduce the logic (the command above).
+5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from these docs alone.
+
+If any step fails, v0 is not ready.
+
+## Current status
+
+- ✅ Step 4 (rerun the open scorer locally, reproduce the hash) — **works today** via `aa_score_runner`.
+- ✅ CI harness gate runs the scorer on every PR.
+- ⏳ Steps 1–3, 5 (HF Space submission flow + signed ledger) — in progress; require the HF Space deploy (needs an HF token / maintainer authorization).

+# RuView Calibration Service (reference implementation)
+
+Turn a **shared WiFi-CSI pose base model** into a room-specific one with a **30-second labeled
+calibration** and a **~11 KB per-room LoRA adapter**. This is the deployable resolution of the
+cross-subject / cross-environment generalization problem (full study: [ADR-150 §3.3–3.6](../../docs/adr/ADR-150-rf-foundation-encoder.md)).
+
+## Why
+
+Zero-shot WiFi pose generalizes poorly to a **new room or new person** — an unseen room can drop a
+strong model to near-random. But that gap is **not** algorithmically closeable (CORAL, DANN,
+instance-norm, contrastive foundation-pretraining all failed) and **not** closeable by collecting
+more subjects (saturates ~64%). It **is** closeable, cheaply, at deployment time: a handful of
+labeled frames from the actual room pin down its multipath instantly.
+
+| Deployment case | Zero-shot | + in-room calibration |
+|-----------------|----------:|----------------------:|
+| Same room, new person (cross-subject) | 64% | **76%** (200 samples) |
+| **New room + new person (cross-environment)** | **~10%** | **60% @ 5 samples → 73% @ 200** |
+
+**Verified demo (this code, source-only base on an unseen MM-Fi room E04):**
+`zero-shot 3.09% → after 200-sample calibration 74.29%` (+71 pts).
+
+## How it works
+
+A frozen shared **base** (transformer + temporal attention pool + skeleton-graph head, the published
+[`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)) plus a
+tiny **LoRA adapter** (rank 8 on the input projection + pose head — **11,200 params ≈ 11 KB int8 /
+22 KB fp16**) fitted per room. Thousands of room-adapters hang off one base.
+
+## Usage
+
+```bash
+# 1) Capture a short labeled clip in the deployment room -> calib.npz {X:[N,3,114,10], Y:[N,17,2]}
+#    (~100–200 samples recommended; below ~20 the adapter can underperform zero-shot)
+
+# 2) Fit the per-room adapter (~11 KB):
+python calibrate.py --base pose_mmfi_best.pt --data calib.npz --out room.adapter.npz
+
+# 3) Run calibrated inference (base + room adapter):
+python infer.py --base pose_mmfi_best.pt --adapter room.adapter.npz --data frames.npz --out kp.npy
+#    omit --adapter to run the uncalibrated (zero-shot) base
+```
+
+`X` is CSI amplitude `[N, 3 antennas, 114 subcarriers, 10 frames]` (per-sample standardization is
+applied internally). `Y` is `[N,17,2]` COCO keypoints in `[0,1]`.
+
+## Calibration budget (measured, rank-8 LoRA, 3 seeds — ADR-150 §3.5)
+
+| Labeled samples/room | cross-subject | cross-environment |
+|---------------------:|--------------:|------------------:|
+| 0 (zero-shot) | 64% | ~10% |
+| 5 | — | 60% |
+| 20 | 66% | 66% |
+| 50 | 70% | 70% |
+| 200 | 72% | 73% |
+
+Knee at ~50 samples (~70%); **below ~20 samples the adapter can hurt** (too few to fit reliably).
+
+## Two models, two producers (not interchangeable)
+
+Adapters are **model-specific**. There are two calibration producers here:
+
+| Producer | Target model | Input | Adapter format | Consumer |
+|----------|--------------|-------|----------------|----------|
+| `calibrate.py` | MM-Fi **transformer** (`pose_mmfi_best.pt`, 3×114×10) | `[N,3,114,10]` | `.npz` (`proj`/`head` LoRA) | this Python `infer.py` |
+| `cog_calibrate.py` | cog **conv+MLP** (`pose_v1.safetensors`, 56×20) | `[N,56,20]` | `.safetensors` (`fc1.a`/`fc1.b`/`fc2.a`/`fc2.b`) | Rust `cog-pose-estimation run --adapter` |
+
+```bash
+# Produce a cog-format per-room adapter for the deployed Rust pose engine:
+python cog_calibrate.py --base pose_v1.safetensors --data calib.npz --out room.safetensors
+# then in the cog runtime:
+cog-pose-estimation run --config <cfg> --adapter room.safetensors
+```
+
+Same LoRA *mechanism* (ADR-150 §3.5), different architecture and key layout — an adapter from one
+producer will not load into the other model.
+
+## Notes
+
+- **Calibration only helps when the base hasn't already seen the room.** The published flagship was
+  trained on MM-Fi `random_split`, so calibrating it on an MM-Fi subject is a near-no-op (it already
+  saw them); for a genuinely new real-world room it is zero-shot and calibration applies. To
+  *reproduce the demo* on a held-out MM-Fi room, train a source-only base (exclude the target
+  environment) — see `ADR-150 §3.6` and the few-shot harness in `aether-arena/staging/`.
+- Adapter is saved fp16 (~22 KB); quantize to int8 for the ~11 KB on-device form.
+- Inference is real-time on CPU (the 75 K-param `micro` variant runs in 0.135 ms single-thread x86;
+  see [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](../../docs/benchmarks/wifi-pose-efficiency-frontier.md)).

+Each row is hash-chained to the previous one: ``row_hash = sha256(canonical_row

+# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
+
+> Public leaderboard. Private evaluation split. Open scorer. Signed results.
+
+The field's standard yardstick for camera-free **spatial intelligence** (pose, presence,
+occupancy, tracking, vitals) from RF/WiFi and, over time, mmWave / UWB / multimodal.
+
+- **Project-agnostic** — any team, framework, or modality enters; RuView donated the seed
+  scorer and is scored like everyone else.
+- **Benchmark-first** — the board starts empty; every row is a real scoring-pipeline
+  **witness** (`inputs_sha256` + `proof_sha256` + `harness_version`) in an append-only,
+  hash-chained, tamper-evident ledger.
+- **Reproducible** — the scorer is open; reproduce any proof hash + repeatability locally.
+
+Spec: [ADR-149](https://github.com/ruvnet/RuView/blob/main/docs/adr/ADR-149-public-community-leaderboard-huggingface.md).
+Source + open scorer: https://github.com/ruvnet/RuView/tree/main/aether-arena
+
+Non-commercial (CC BY-NC 4.0): the v0 eval split derives from MM-Fi (CC BY-NC); AA is operated non-commercially.

+ABOUT = """
+**AetherArena** is the official, project-agnostic **Spatial-Intelligence Benchmark** —
+camera-free pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over
+time, mmWave / UWB / radar / multimodal). It is **not** a single-vendor board: any
+team, framework, or modality enters, and every entrant — including the RuView baseline
+that donated the seed scorer — is scored by the identical, open, pinned harness.
+
+The scorer reuses RuView's released `wifi-densepose-train` acceptance harness
+(`ruview_metrics` + ablation). You submit a **model, not predictions**; it is scored
+against a **private** MM-Fi held-out split; one **witness** row (inputs hash + proof
+hash + harness version) is appended to a **hash-chained, tamper-evident ledger**.
+
+**For industry:** a vendor-neutral, auditable way to compare RF-sensing models on equal
+footing — the same standardized splits, the same metric definition, the same signed,
+reproducible ledger. No more "trust our number on our split." Vendors, labs, and startups
+all submit through one pipeline and are scored identically.
+
+**Generalization Track (roadmap):** the headline isn't a single in-domain number — it's a
+battery of honest tracks: MM-Fi `random_split` (in-domain), `cross_subject` (unseen people),
+cross-room, cross-device, and confidence-calibration (ECE). Cross-subject is the real
+deployment frontier and is treated as the flagship hard benchmark.
+
+Spec: ADR-149. v0 ranks **pose, presence, edge-latency, determinism**. Tracking &
+vitals activate when their ground truth lands; **privacy-leakage** is gated until the
+membership-inference attacker ships. Source + the open scorer:
+https://github.com/ruvnet/RuView/tree/main/aether-arena
+"""
+
+SUBMIT = """
+### Submit a model
+
+1. Write a manifest — [`schema/aa-submission.toml`](https://github.com/ruvnet/RuView/blob/main/aether-arena/schema/aa-submission.toml):
+   declare your model ref, category, the ADR-145 feature set (F0 CSI … F3 BFLD), and the tensor I/O contract.
+2. Provide your model artifact (`.safetensors` / `.rvf` / LoRA adapter).
+3. It moves through `submitted → validated → quarantined → smoke_scored → full_scored → published`,
+   scored in a no-network, read-only sandbox against the private split.
+4. Your signed witness row appears on the leaderboard.
+
+**You submit a model, never predictions** — predictions on data you hold prove nothing.
+"""
+
+VERIFY = """
+### Verify it's fair (you don't have to trust us)
+
+The scorer is open and reproducible. Reproduce the determinism proof + repeatability locally:
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView/v2
+# determinism gate (same as CI):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# repeatability — N runs, one identical proof hash:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# verify the append-only witness ledger chain:
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+```
+
+A stranger must be able to: submit → get a deterministic score → see the signed row →
+rerun the scorer locally → understand why the rank is fair. That is the launch gate (ADR-149 §7).

+# WiFlow-STD (DY2434) Benchmark Results — ADR-152 §2.2
+
+Upstream: <https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling>
+pinned at `06899d29` (2026-04-05), Apache-2.0. Dataset: Kaggle `kaka2434/wiflow-dataset`
+(12.8 GB archive → 15.5 GB extracted; 360,000 windows of 540×20 CSI + 15-keypoint 2D labels).
+
+Published claims (README "Setting 1"): PCK@20 97.25%, PCK@30 98.63%, PCK@40 99.16%,
+PCK@50 99.48%, MPJPE 0.007 m, 2.23M params, 0.07 GFLOPs.
+
+## Measurement (a): their model on their data
+
+### Artifact verification (MEASURED, 2026-06-10, this repo `eval_repro.py`)
+
+| Check | Result |
+|---|---|
+| Parameter count | **2,225,042 (2.23M) — matches claim** |
+| FLOPs (torch profiler, batch 1) | ~0.055 GFLOPs — consistent with 0.07B claim |
+| CPU latency (Windows box, torch 2.12 CPU) | 13.2 ms/window @ batch 1 (76/s); 2.48 ms/sample @ batch 64 (403/s) |
+| Checkpoint load | `weights_only=True` (no pickle code execution) |
+
+### Released checkpoint does NOT reproduce the claims — REFUTED as shipped
+
+Running the released `best_pose_model.pth` through the released code on the released
+dataset with the released split procedure (seed-42 file-level 70/15/15; 54,000 test
+samples) yields:
+
+| Metric | Published | Measured (shipped checkpoint) |
+|---|---|---|
+| PCK@20 | 97.25% | **0.08%** |
+| PCK@30 | 98.63% | 0.78% |
+| PCK@40 | 99.16% | 5.53% |
+| PCK@50 | 99.48% | 15.42% |
+| MPJPE | 0.007 | **NaN** (dataset contains NaN CSI windows) |
+
+Raw output: `results/repro_a.json`.
+
+Diagnostics (on 2,000 NaN-free windows from the first files of the dataset, i.e.
+mostly would-be *training* data — so this is not a split mismatch):
+
+- Predictions correlate with targets (Pearson r ≈ 0.76) — the checkpoint is a trained
+  model, but in a **different keypoint normalization/order** than the released data.
+- Best-case post-hoc global per-axis affine correction: PCK@20 ≈ 20%.
+- Best-case per-keypoint affine correction (15×2 fitted transforms — generous
+  cheating): PCK@20 ≈ 72%, still far below 97.25%.
+- Pred↔target keypoint correspondence matrix is degenerate (multiple predicted
+  keypoints best-match the same target joint) — keypoint convention mismatch.
+
+### Reproducibility defects in the released artifacts
+
+1. `models/__init__.py` imports `TemporalConvNet`, which `models/tcn.py` does not
+   define — **the published code does not import/run as-is**.
+2. The released root checkpoint uses pre-rename module names (`att.*`, `final_conv.*`)
+   vs the published code (`attention.*`, `decoder.*`) — same shapes/param count, but
+   confirms the checkpoint predates the published code.
+3. The second shipped checkpoint (`cross_dataset_test/WiFlow/best_pose_model.pth`) is
+   a **different architecture** (342-channel input = MM-Fi layout, 3 TCN layers,
+   3-channel/3D decoder) — not usable on their own dataset.
+4. `run.py` ignores `--data_dir` and hardcodes `../preprocessed_csi_data`.
+5. The released dataset's final 13 files (indices 487–499; 9,072 windows, 2.52%)
+   are corrupted: NaN values plus garbage amplitudes up to 3.4e38 (float32 max) in
+   data that is otherwise [0,1]-normalized. Upstream code has no NaN/inf handling;
+   training as published on this download diverges — the first corrupted batch
+   overflows fp16 autocast and permanently poisons BatchNorm running statistics
+   (GradScaler step-skipping does not protect BN). The authors' training curves
+   show normal convergence, so their local data evidently differed from the
+   Kaggle upload. Window masks: `results/nan_windows_mask.npy`,
+   `results/big_windows_mask.npy`.
+
+### Reproducing the corruption masks
+
+The two mask files (9,070 NaN/Inf windows, 9,072 with |amplitude| > 1.5;
+union 9,072, all in dataset files 487–499) are **committed ground truth**
+(gitignore-negated, ~352 KB each). They can only be regenerated from a
+**pristine** Kaggle download: `remote/clean_v2.py` repairs the dataset by
+zeroing the corrupted windows in place, after which the corruption evidence
+is gone and a rescan returns all-False. `generate_corruption_masks.py`
+re-derives them (chunked scan, criteria: any non-finite value OR
+max |finite| > 1.5 per 540×20 window) and refuses to write all-False masks,
+which indicate a cleaned copy. Verified 2026-06-11: a regeneration from the
+local pristine download is bit-identical to the committed masks.
+
+### Retraining result (MEASURED, 2026-06-10): claims APPROXIMATELY REPRODUCED
+
+Since the shipped checkpoint is unusable, measurement (a) fell back to retraining
+with upstream code + defaults (seed 42, batch 64, early-stopped at epoch 41 of 50,
+best epoch 36, ~75 s/epoch) on ruvultra (RTX 5080). Deviations, all forced and
+documented: one-line fix for defect (1); torch 2.x+cu128 instead of pinned 2.3.1
+(Blackwell sm_120 unsupported); the 9,072 corrupted windows (defect 5) zeroed
+entirely — without this the published pipeline produces NaN from epoch 1 (observed).
+Scripts mirrored in `remote/`; raw metrics in `results/eval_retrained.json`.
+
+| Metric | Published | Retrained (full test, 54,000) | Retrained (corruption-free, 52,560) |
+|---|---|---|---|
+| PCK@20 | 97.25% | **96.09%** | **96.61%** |
+| PCK@30 | 98.63% | 97.89% | 98.23% |
+| PCK@40 | 99.16% | 98.58% | 98.79% |
+| PCK@50 | 99.48% | 98.99% | 99.11% |
+| MPJPE | 0.007 | 0.0098 | 0.0094 |
+
+Within ~0.6–1.2 PCK points of every published figure (single run, corrupted train
+windows zeroed, different torch/GPU). **Verdict: the accuracy claims are credible
+and approximately reproducible — but only after repairing the released dataset and
+code.** Val best: PCK@20 96.99%, MPJPE 0.0086 (epoch 36).
+
+One more defect found during the run:
+
+6. `train.py` calls `plot_training_history`, which is not defined anywhere — the
+   built-in post-training test evaluation is unreachable as published (crashes
+   with NameError after training completes).
+
+## ADR-152 §2.2 citation rule
+
+Evidence grade for the WiFlow-STD accuracy claims after measurement (a):
+**MEASURED-EQUIVALENT (96.1–96.6% PCK@20 reproduced by retraining; shipped
+checkpoint REFUTED; dataset/code require repairs)**. RuView docs may cite
+"~96% PCK@20 (our reproduction)" — still **not comparable** to our 17-keypoint
+ESP32 numbers (different hardware, 5 subjects, in-domain random split,
+15 keypoints).
+
+## Edge optimization (measured)
+
+ADR-152 "optimize beyond SOTA" track, 2026-06-10, this Windows box (Windows 11,
+16 torch threads, torch 2.12.0+cpu, onnxruntime 1.26.0). Subject: the retrained
+checkpoint `results/retrained_best_pose_model.pth` (2,225,042 fp32 params).
+Scripts: `quantize_bench.py`, `onnx_bench.py`, `eval_ort_accuracy.py`.
+Raw numbers: `results/edge_optimization.json`.
+
+Accuracy is on a **10,000-window seed-42 random subset** of the corruption-free
+test split (same seed-42 file-level 70/15/15 split as `eval_repro.py`; 54,000
+test windows, 1,440 corrupted excluded via `results/nan_windows_mask.npy` |
+`results/big_windows_mask.npy`, leaving 52,560; subset drawn with
+`np.random.default_rng(42)`). The fp32 subset PCK@20 (96.68%) matches the full
+clean-test figure (96.61%), so the subset is representative.
+
+Latency is CPU ms/window, median of repeated runs, 3 interleaved repetitions
+per variant (medians below; run-to-run spread on this box is large, roughly
+±20-40% at batch 1 — reps are in the JSON).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| torch fp32 (baseline) | 9.07 MB | 11.0 | 2.27 | 96.68% | 99.15% | 0.00936 |
+| torch fp16 (`.half()`) | **4.58 MB** | 24.3 | 2.42 | 96.68% | 99.15% | 0.00946 |
+| torch int8 dynamic | 9.07 MB (unchanged) | 15.6 | 2.06 | 96.68% (identical) | 99.15% | 0.00936 |
+| ONNX fp32 (onnxruntime) | 8.97 MB | **3.2** | **2.0** | 96.68% | 99.15% | 0.00936 |
+| ONNX int8 (ORT dynamic, supplementary) | **2.44 MB** | 6.5 | 5.8 | 96.52% | 99.15% | 0.01108 |
+
+Findings:
+
+- **torch dynamic INT8 quantizes nothing on this model.** The architecture has
+  **zero `nn.Linear` layers** — it is entirely Conv1d (21) + Conv2d (22) +
+  BatchNorm. `torch.ao.quantization.quantize_dynamic` (requested over
+  `{Linear, Conv1d, Conv2d}`) converted **0 modules / 0.0% of params**: dynamic
+  quantization only has kernels for Linear/RNN-family modules and silently
+  skips convolutions. The "int8" model is bit-identical to fp32 (same outputs,
+  same 9.07 MB). Conv quantization would require static (PTQ) quantization
+  with calibration — out of scope here; the ORT dynamic path below is the
+  honest int8 datapoint.
+- **fp16 halves size for free accuracy-wise** (PCK@20 −0.005 pt, MPJPE
+  +0.0001) but is *slower* on CPU at batch 1 (~2.2×) — torch CPU fp16 conv
+  kernels are emulated. fp16 is a storage/transport format here, not a CPU
+  runtime win.
+- **ONNX Runtime is the real batch-1 latency win: ~3.4× faster than torch**
+  (3.2 vs 11.0 ms/window) at identical accuracy (parity 2.4e-7).
+
+### Verdict on the paper's "~2.2 MB int8" claim
+
+**Plausible but not free, and unreachable by the obvious PyTorch route.**
+2,225,042 params × 1 byte ≈ 2.2 MB assumes *every* parameter quantizes.
+PyTorch dynamic quantization — the one-liner most readers would reach for —
+yields **9.07 MB (0% quantized)** because the model has no Linear layers.
+ONNX Runtime dynamic quantization, which does have int8 conv weight support,
+gets **2.44 MB** (close to the claim; the overhead is BatchNorm params/buffers
+and quantization scales kept in fp32) at a measurable accuracy cost:
+PCK@20 96.68 → 96.52% (−0.16 pt) and MPJPE 0.00936 → 0.01108 (+18%), and
+~2× slower inference than ONNX fp32 (ConvInteger kernels). The paper does not
+state a method or an int8 accuracy; treat "2.2 MB" as a weight-arithmetic
+estimate, achievable in practice only via conv-capable quantization toolchains
+and with a small accuracy penalty.
+
+### ONNX export status
+
+**Works.** Exported via the TorchScript exporter (`dynamo=False`), opset 17,
+with a dynamic batch axis — `results/retrained_fp32_dynamic.onnx` (8.97 MB),
+verified to run at batch 1/2/64. The axial attention's
+`view(N*W, C, H)` reshape traced correctly (sizes recorded as graph ops, not
+baked constants). The dynamo exporter also captures the graph but crashed on
+this box writing a ✅ to a cp1252 console (cosmetic Windows encoding issue, not
+a model blocker). Parity vs torch on the stored fixture
+(`results/parity_fixture.npz`, batch 2, seed 42): **max abs diff 2.4e-7 —
+PASS** (< 1e-4). ORT-quantized int8 model: `results/retrained_int8_ort_dynamic.onnx`.
+
+### Static PTQ (calibrated) — follow-up
+
+Follow-up to the dynamic-int8 row above (2026-06-10, same box, onnxruntime
+1.26.0): ONNX Runtime **static** post-training quantization
+(`quantize_static`, QDQ format, per-channel int8 weights + int8 activations)
+of the same fp32 export, calibrated on **corruption-free TRAINING-split
+windows only** (seed-42 file-level split, same masks; 1,000 windows for
+MinMax, 512 for the histogram calibrators; never test windows). Scopes:
+"conv-only" (`op_types_to_quantize=["Conv"]` — the attention path exports as
+Einsum/Softmax, which ORT never quantizes anyway, so "all-ops" additionally
+quantizes the elementwise Mul/Sigmoid/Add/AveragePool glue). Accuracy on the
+identical 10k-window seed-42 corruption-free test subset; latency median of
+3 interleaved reps (fp32/dynamic re-benched in-session as references).
+Script: `static_ptq_bench.py`; raw: `results/edge_optimization.json`
+(`onnx_static_ptq`).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| ONNX fp32 (reference) | 8.97 MB | 2.5 | 1.9 | 96.68% | 99.15% | 0.00936 |
+| ORT dynamic int8 (baseline) | **2.44 MB** | 5.7 | 4.6 | 96.52% | 99.15% | 0.01108 |
+| static QDQ **Percentile(99.99) conv-only** | 2.53 MB | 5.3 | 4.7 | 96.61% | 99.16% | **0.01031** |
+| static QDQ MinMax conv-only | 2.53 MB | 5.2 | 3.3 | **96.63%** | 99.19% | 0.01084 |
+| static QDQ Entropy conv-only | 2.53 MB | 5.2 | 3.1 | 96.60% | 99.19% | 0.01078 |
+| static QDQ MinMax all-ops | 2.60 MB | 6.5 | 3.9 | 95.45% | 99.14% | 0.01486 |
+| static QDQ Entropy all-ops | 2.60 MB | 5.7 | 4.1 | 95.30% | 99.13% | 0.01510 |
+| static QDQ Percentile all-ops | 2.60 MB | 5.3 | 4.3 | 96.39% | 99.17% | 0.01218 |
+
+**Verdict: static PTQ (conv-only) is the new best int8 point on accuracy —
+but only modestly, and it does not fix int8's latency penalty.**
+
+- **Accuracy: beats dynamic.** All three conv-only calibrations land at
+  PCK@20 96.60–96.63% (vs dynamic 96.52%, fp32 96.68% — recovers ~⅔ of the
+  dynamic gap) and MPJPE 0.0103–0.0108 (vs dynamic 0.01108). Best MPJPE:
+  Percentile conv-only, +10% over fp32 instead of dynamic's +18%.
+- **Size: slightly worse.** 2.53 MB vs 2.44 MB (+3.6%) — QDQ nodes and
+  per-channel scales cost a little; BatchNorm stays fp32 in both (the 12 BNs
+  follow Slice/Einsum/Reshape, never Conv, so they cannot be folded).
+- **Latency: a wash vs dynamic, still ~2× slower than ONNX fp32 at batch 1.**
+  Batch-1 medians 5.2–5.3 vs dynamic 5.7 ms/win in-session — within this
+  box's ±20–40% noise. Batch 64 leans static (3.1–3.3 for MinMax/Entropy
+  conv-only vs 4.6), same caveat.
+- **All-ops QDQ is strictly worse**: up to −1.4 pt PCK@20 and +60% MPJPE for
+  zero size/latency benefit — int8 activations through the elementwise glue
+  around the attention blocks is where the damage is. Conv-only is the right
+  scope.
+- Negative result worth recording: **Entropy calibration is a no-op here** —
+  on an identical calibration set it selects full-range thresholds
+  bit-identical to MinMax (all 247 scales equal; verified on a 64-window
+  smoke set). Also, ORT 1.26's `CalibMaxIntermediateOutputs` raises a
+  spurious "No data is collected" when the batch count divides the chunk
+  size (worked around in the script).
+
+Deployment guidance: need speed → ONNX fp32 (3.2 ms b1). Need int8 weights
+for size → static QDQ conv-only (Percentile or MinMax,
+`results/retrained_int8_static_percentile_conv.onnx`), which strictly
+dominates dynamic int8 on accuracy at ~equal latency and +0.09 MB.
+
+## Efficiency sweep (MEASURED, overnight 2026-06-10/11)
+
+ADR-152 beyond-SOTA track: compact purpose-built variants of the WiFlow-STD
+architecture, trained from scratch on the same cleaned dataset, identical
+seed-42 file-level split, loss and protocol as the measurement-(a) reference
+(fp32, batch 64, ≤50 epochs, patience 5; RTX 5080, ~22–29 min/variant).
+Variant transforms are pure channel/group/stride scalings of an
+architecture-exact parameterized model (validated: reproduces 2,225,042 params
+at the reference config). Scripts: `remote/sweep/`; raw:
+`results/efficiency_sweep.jsonl`; checkpoints `results/{half,quarter,tiny}_best.pth`
+(gitignored).
+
+| Variant | Params | vs 2.23M | Clean-test PCK@20 | PCK@50 | MPJPE | Best epoch |
+|---|---|---|---|---|---|---|
+| full (reference, meas. a) | 2,225,042 | 1× | 96.61% | 99.11% | 0.0094 | 36 |
+| **half** | **843,834** | **0.38×** | **96.62%** | **99.47%** | **0.00898** | 23 |
+| quarter | 338,600 | 0.15× | 96.05% | 99.43% | 0.00928 | 50 |
+| tiny | 56,290 | 0.025× | 94.11% | 99.36% | 0.0125 | 47 |
+
+Findings:
+
+- **The half model (843k params) strictly dominates the full reference** on
+  this dataset — equal PCK@20, better PCK@50 and MPJPE, converges in fewer
+  epochs. The published 2.23M architecture is over-parameterized for its own
+  benchmark.
+- **tiny (56k params, 1/39.5) holds 94.11% PCK@20** — a ~220 KB fp32 /
+  ~60 KB int8-class model in reach of severely constrained edge targets,
+  at −2.5 pt from the full reference.
+- Caveats: in-domain (5-subject random-file split) like every number on this
+  dataset; single run per variant; corruption-free test subset (52,560).
+  Cross-domain behavior of compact variants is untested — ADR-150's evidence
+  says capacity *hurts* cross-subject, so the compact end may generalize no
+  worse, but that is a hypothesis, not a measurement.
+
+### Compact-variant edge artifacts (MEASURED, 2026-06-11)
+
+Edge pipeline for the **tiny** checkpoint (56,290 params), same machinery and
+protocol as the full-model edge rows above (this Windows box, torch
+2.12.0+cpu, onnxruntime 1.26.0; dynamic-batch opset-17 TorchScript export;
+static QDQ **Percentile(99.99) conv-only** int8 calibrated on **512**
+corruption-free TRAIN-split windows; accuracy on the identical 10k-window
+seed-42 clean test subset; latency = median ms/window over 3 interleaved
+reps, with the full-model fp32/int8 sessions interleaved as same-session
+references). Script: `tiny_edge_bench.py`; raw:
+`results/edge_optimization.json` (`tiny_variant`). Torch-vs-ORT parity on the
+stored fixture input: **max abs diff 1.5e-7 — PASS** (< 1e-4). The tiny fp32
+subset PCK@20 (94.11%) matches the full clean-test sweep figure (94.11%)
+exactly, so the subset remains representative.
+
+Two forced deviations, both recorded in the JSON:
+
+1. **Adaptive-pool export rewrite.** tiny's derived stride schedule
+   `[2,1,1,1]` leaves feature width 16, and the TorchScript exporter rejects
+   `AdaptiveAvgPool2d((15,1))` when 15 is not a factor of the input height
+   (the full model never hit this — its width was exactly 15). Since the
+   pool over a fixed-size map is a fixed linear operator, the export wrapper
+   replaces it with `mean(-1)` (W axis, a factor) + a constant averaging
+   matmul using PyTorch's exact bin rule; the parity check (vs the original
+   torch model with the real pool) proves exactness.
+2. **Calibration count 512, not "~500"**: ORT 1.26's histogram collector
+   `np.asarray()`'s the per-batch maxima, so the calibration count must be a
+   multiple of the 64-window calibration batch or the ragged last batch
+   crashes it (the earlier static-PTQ run dodged this by using exactly 512).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| full ONNX fp32 (same-session ref) | 8.97 MB | 2.27 | 1.42 | 96.68% | 99.15% | 0.00936 |
+| full static QDQ Percentile conv-only (same-session ref) | 2.53 MB | 5.53 | 3.82 | 96.61% | 99.16% | 0.01031 |

+
+(tiny torch `.pth` checkpoint for reference: 0.34 MB on disk; 56,290 fp32
+params ≈ 225 KB of weights.)
+
+Findings:
+
+- **The smallest deployable WiFlow-class model is the tiny ONNX fp32
+  artifact: ~295 KB on disk, 0.66 ms/window batch-1 CPU (~1,500 windows/s),
+  94.1% PCK@20** — 30× smaller and ~3.4× faster (in-session) than the full
+  ONNX fp32 model for −2.6 pt PCK@20.
+- **int8 is a bad trade at this scale.** Static QDQ conv-only — the recipe
+  that cost the full model only 0.07 pt — costs tiny **−1.43 pt** PCK@20
+  (94.11 → 92.68%) and +19% MPJPE, saves only 47 KB (−16%; QDQ scales and
+  the fp32 BN/attention glue are proportionally larger in a small graph),
+  and is *slower* than tiny fp32 (0.85 vs 0.66 ms b1; 1.03 vs 0.24 ms b64 —
+  QDQ kernel overhead dominates when the convs are this small). A 56k-param
+  model has little redundancy left to absorb weight+activation rounding.
+- Deployment guidance, compact edition: ship tiny as **ONNX fp32** — at
+  295 KB the int8 size saving solves no real constraint and costs accuracy
+  and speed. If ~250 KB vs ~295 KB ever matters, weight-only quantization
+  would be the thing to try next, not QDQ.
+
+## Measurement (b): BLOCKED-ON-DATA (attempted 2026-06-10)
+
+The fine-tune-on-ESP32 measurement stopped at dataset characterization, per the
+pre-registered stop rule (<2,000 paired windows). Findings (MEASURED):
+
+- **Only one trainable paired dataset exists**: `ruvultra:~/work/cog-pose-train/paired.jsonl`
+  — 1,077 windows (one subject, one room, one 29.9-min session, single node;
+  CSI [56, 20]; 17 COCO keypoints, MediaPipe confidence mean 0.44 — only 264
+  windows pass ADR-079's own conf>0.5 training filter). Prior measured attempts
+  on this exact set: 0–3% torso-PCK@20 (temporal splits, three independent
+  pipelines). Fine-tuning a 2.23M-param model on ~860 train windows would
+  measure memorization, not transfer.
+- **The April session behind the old "92.9% PCK@20" claim is lost** (345
+  samples, 35 subcarriers; raw CSI gone from ruvzen/ruvultra/cognitum-v0; only
+  a 69-sample predictions+GT holdout survives at `models/wiflow-real/eval-holdout.jsonl`).
+- **Forensic recheck of that holdout RETRACTS the 92.9% figure**: the trainer's
+  `pck()` used an absolute 0.2 image-unit threshold (not torso-normalized) and
+  the model output a **constant pose** (pred std 0.0000 across 69 near-static
+  frames; a mean predictor scores 100% under the same protocol). The
+  torso-normalized PCK@20 on the same holdout is 19.1%. This corroborates the
+  2026-05-11 audit retraction (CHANGELOG, PR #535); stale doc citations were
+  removed 2026-06-10 (user-guide, readme-details, ADR-152 §2.1.3). The §2.2
+  no-citation rule now applies to ADR-079 accuracy claims.
+
+Unblock criteria: a paired collection session of ≥2k windows (≈35+ min at the
+observed stride; multi-pose, conf>0.5, ideally with the §2.1.3 two-checkerboard
+calibration), plus a re-baselined our-pipeline number under torso-PCK@20 on the
+same split. WiFlow-STD assets stand ready on ruvultra (`~/wiflow-std-bench/`).
+Also worth investigating: ADR-079's protocol predicts ~9k windows per 30 min;
+the May session under-delivered ~8× (aligner drop rate?).
+
+## Measurement (b) (MEASURED 2026-06-10/11)
+
+The data baseline unblocked: the 2026-06-10 22:10–22:40 collection session produced
+**2,046 paired windows** (`ruvultra:~/wiflow-std-bench/paired-20260610.jsonl`; ONE
+subject, ONE room, ONE ESP32 node, varied poses: walk/raise/squat/kick/wave/turn/
+jump/sit; aligner `scripts/align-ground-truth.js`, non-overlapping 20-frame windows
+~0.42 s; 17 COCO keypoints in normalized [0,1] camera coords; MediaPipe confidence
+mean 0.802, min 0.692 — all windows pass the conf>0.5 filter). The −4 h timestamp
+bug and the empty-frame confidence-dilution aligner findings are recorded
+separately; results only here. Trained on ruvultra (RTX 5080, torch 2.11+cu128,
+fp32, batch 32, GPU shared with the efficiency sweep). Scripts mirrored in
+`remote/measb/`; raw metrics + full training curves in `results/measurement_b.json`.
+
+### Two new aligner/dataset findings (forced deviations, MEASURED)
+
+1. **`csi_shape` is heterogeneous, not [70, 20]**: 1,347× [70,20], 284× [134,20],
+   243× [26,20], 130× [12,20], 42× [20,20]. The ESP32 stream emits mixed frame
+   types and `extractCsiMatrix` stamps each window's subcarrier count from
+   `window[0].subcarriers`, zero-padding/truncating the other frames — even
+   native-70 windows contain ~20.4% internally zero-padded short frames
+   (subcarriers 40–69 all-zero). Handling: the primary suite ("all 2,046")
+   linearly resamples every frame's subcarrier axis to 70 bins (identity for
+   native-70 frames) so the pre-registered n and split sizes hold; a secondary
+   suite restricts to the 1,347 native [70,20] windows as a homogeneity check.
+2. **Aligner layout bug**: `extractCsiMatrix` fills `matrix[f * nSc + s]`
+   (frame-major) but declares `shape: [nSc, nFrames]` — the stored shape label is
+   transposed relative to the data. Confirmed by coherent per-frame zero-tails;
+   corrected on load (`reshape(nFrames, nSc).T`).
+
+### Protocol (pre-registered, followed)
+
+Temporal split, no shuffling across time: first 70% train (1,432), next 15% val
+(307), last 15% test (307); seed 42 elsewhere. Model: learned 1×1 Conv1d 70→540
+adapter prepended to the upstream WiFlow-STD trunk; K=17 via the parameter-free
+adaptive pool (`AdaptiveAvgPool2d((17,1))` — pretrained weights load strict for
+any K). CSI normalized by the TRAIN-split p99 amplitude (129.7 all / 130.9
+native-70), clipped to [0,1]. Three runs, ≤60 epochs, early-stop patience 8 on
+val MPJPE, AdamW (adapter lr 1e-4; pretrained trunk lr 1e-5, 10× lower; scratch
+all 1e-4), fp32. Pretrained init = the measurement-(a) **retrained** checkpoint
+(`upstream/test/best_pose_model.pth`, ~96% PCK@20 on WiFlow data; the
+`att.`/`final_conv.` key remap from `eval_repro.py` applied defensively — a no-op,
+that checkpoint already uses post-rename keys). Frozen-trunk run: trunk
+`requires_grad=False` **and** held in `.eval()` so BatchNorm running stats cannot
+drift — a pure transfer probe; only the 70→540 adapter (38,340 params) trains.
+
+PCK is torso-normalized with **torso = ‖l_shoulder(5) − l_hip(11)‖** (upstream
+`calculate_pck` math — per-frame norm clamped at 0.01, mean over keypoints ×
+frames — but upstream's `NECK_IDX/PELVIS_IDX = 2, 12` is a 15-keypoint
+convention; on 17-kp COCO those indices are right_eye/right_hip, so the indices
+were replaced, not the math). MPJPE is in normalized image units (not meters).
+
+### Results — primary suite, all 2,046 windows (test = last 307)
+
+| Run | PCK@10 | PCK@20 | PCK@30 | PCK@40 | PCK@50 | MPJPE | pred std | best ep |
+|---|---|---|---|---|---|---|---|---|
+| **mean-pose baseline** (honesty bar) | **73.1%** | **95.9%** | **98.7%** | 99.3% | 99.3% | **0.0148** | 0 (by constr.) | — |
+| (i) pretrained-init, full fine-tune | 26.0% | 65.0% | 88.0% | 96.4% | 98.9% | 0.0313 | 0.0113 | 58/60 |
+| (ii) scratch | 0.0% | 0.0% | 0.0% | 0.0% | 0.0% | 0.2554 | 0.0002 | 4 (stop @13) |
+| (iii) frozen-trunk (adapter only) | 0.0% | 0.0% | 0.2% | 3.2% | 14.4% | 0.1260 | 0.0073 | 59/60 |
+
+Secondary suite (native [70,20] windows only, n=1,347, test=202) reproduces the
+same ordering: mean-baseline 96.0% / pretrained 67.1% / scratch 0.0% /
+frozen-trunk 0.0% PCK@20 (MPJPE 0.0153 / 0.0318 / 0.2236 / 0.1343) — the
+subcarrier-resampling choice does not change any conclusion.
+
+### Interpretation
+
+- **Did pretraining-transfer happen? Partially — as optimization transfer, not
+  feature transfer, and not past the honesty bar.**
+  - *Pretrained vs scratch*: dramatic (65.0% vs 0.0% PCK@20). The pretrained init
+    is the only configuration that trains at all under the pre-registered budget.
+  - *Frozen-trunk*: near-zero (0.0% PCK@20, 14.4% @50). WiFlow-STD's frozen
+    features do **not** transfer to our ESP32 domain through a linear subcarrier
+    adapter — the pretrained benefit is a well-conditioned initialization (incl.
+    calibrated BN/output scales), not reusable CSI→pose features.
+  - *Everything vs mean-pose baseline*: **no run beats it.** A constant
+    train-mean pose scores 95.9% torso-PCK@20 / 0.0148 MPJPE on this test split,
+    because a single subject in one camera frame barely moves in normalized
+    coordinates. The fine-tuned model is a real, non-constant model
+    (pred std 0.0113 > 0 — passes the constant-pose detector that retracted the
+    old 92.9% figure) but its deviations from the mean hurt: it fits train-period
+    temporal dynamics that do not generalize across the temporal split.
+- **Verdict for ADR-152 §2.2(b): fine-tuning WiFlow-STD on this dataset does not
+  demonstrate CSI→pose signal beyond the mean pose.** Until a model beats the
+  mean-pose baseline on a temporal split, no PCK number from this line may be
+  cited as pose-estimation capability.
+
+### Caveats (honest, pre-registered)
+
+- Single subject, single room, single session (30 min), single ESP32 node —
+  in-domain temporal split only; nothing here speaks to cross-room or
+  cross-subject generalization.
+- 2k windows vs the 360k-window WiFlow-STD corpus — **NOT comparable** to the
+  ~96% in-domain measurement-(a) number, and the published 97.25% even less so.
+- The scratch run's total collapse (it cannot even reach the mean pose; its
+  output BatchNorm/SiLU head must learn output scale from random init at lr 1e-4)
+  is an optimization outcome under the fixed budget, not proof the architecture
+  cannot learn from scratch — the pretrained-vs-scratch gap partially reflects
+  this conditioning advantage.
+- Mixed-subcarrier frames (finding 1) mean even the "clean" windows carry ~20%
+  zero-padded frames; collection-side frame-type filtering should precede the
+  next session.
+- Mean-baseline PCK is inflated by low pose variance relative to torso size
+  (~0.2–0.3 image units); PCK@10 (73.1%) shows the same ceiling effect at a
+  stricter threshold — the bar is the bar, but a livelier dataset would lower it.
+
+## Pending
+
+- (b) fine-tune on our ESP32 17-keypoint eval set — **MEASURED 2026-06-10/11**,
+  see above: no run beats the mean-pose baseline; pretraining transfers as
+  optimization aid only.
+- (c) our internal WiFlow on their dataset (15-keypoint subset mapping) — also
+  affected: there is currently no validated internal pose model to compare
+  (the 92.9% artifact is retracted; the MM-Fi SOTA models in ADR-150 §3 are a
+  different input domain).

+
+That irreversibility is exactly why the two committed mask files under
+results/ (gitignore-negated) are the canonical ground truth: once a download
+has been cleaned, the masks can NEVER be regenerated from it. Only run this
+on a fresh `kagglehub.dataset_download("kaka2434/wiflow-dataset")`.

+"""ADR-152 SS2.2 measurement (b): WiFlow-STD fine-tuned on our fresh ESP32 paired dataset.
+
+Dataset: ~/wiflow-std-bench/paired-20260610.jsonl -- 2,046 paired windows collected
+2026-06-10 22:10-22:40 (ONE subject, ONE room, ONE ESP32 node, varied poses).
+Per record: csi = flat float32 list, csi_shape, kp = 17 COCO [x, y] normalized [0,1]
+camera coords, conf (MediaPipe mean confidence, all > 0.5 in this set), ts_start/ts_end.
+Aligner: scripts/align-ground-truth.js, non-overlapping 20-frame windows (~0.42 s each).
+
+Dataset findings (MEASURED on this file, 2026-06-10):
+  - csi_shape is HETEROGENEOUS, not uniformly [70, 20]: 1,347x [70,20], 284x [134,20],
+    243x [26,20], 130x [12,20], 42x [20,20]. The ESP32 stream emits mixed frame types
+    and the aligner stamps each window's subcarrier count from frame[0]
+    (extractCsiMatrix: nSc = window[0].subcarriers), zero-padding/truncating the rest.
+    Even native-70 windows contain ~20.4% internally zero-padded short frames
+    (subcarriers 40..69 all-zero for those frames).
+  - LAYOUT BUG: the aligner fills matrix[f * nSc + s] (frame-major) but declares
+    shape [nSc, nFrames]. The true layout is (frame, subcarrier); we reshape
+    (nFrames, nSc) and transpose. Confirmed by coherent per-frame zero-tails.
+  - Handling here (primary suite, "all2046"): every frame's subcarrier axis is
+    linearly resampled to 70 bins (np.interp over a normalized index domain;
+    identity for native-70 frames) so the pre-registered n=2,046 and split sizes
+    hold. Secondary suite ("native70") restricts to the 1,347 native [70,20]
+    windows (temporal 70/15/15 of those) as a homogeneity robustness check.
+
+Pre-registered protocol (followed exactly):
+  1. TEMPORAL split (records are time-sorted; asserted): first 70% train (1,432),
+     next 15% val (307), last 15% test (307). No shuffling across time. Seed 42
+     for everything else.
+  2. Model: upstream WiFlow-STD trunk (WiFlowPoseModel) with a learned 1x1 Conv1d
+     projection 70->540 prepended, and K=17 via the parameter-free adaptive pool
+     (AdaptiveAvgPool2d((17, 1)) instead of (15, 1)) -- pretrained weights load
+     for any K. CSI normalization: divide by the TRAIN-split 99th-percentile
+     amplitude, clip to [0, 1] (documented in output JSON).
+  3. Three runs, <=60 epochs, early-stop patience 8 on val MPJPE, batch 32,
+     AdamW, fp32 (no autocast):
+       (i)   pretrained-init: trunk init from upstream/test/best_pose_model.pth
+             (the measurement-(a) retrained checkpoint, ~96% PCK@20 on WiFlow data;
+             key remap att.->attention. / final_conv.->decoder. applied defensively
+             as in eval_repro.py -- a no-op for this checkpoint, which already uses
+             the new names). Discriminative lr: adapter 1e-4, trunk 1e-5.
+       (ii)  scratch: same architecture, random init, all params lr 1e-4.
+       (iii) frozen-trunk: pretrained trunk frozen (requires_grad=False AND held in
+             .eval() so BatchNorm running stats cannot drift -- pure transfer probe);
+             only the 70->540 adapter trains, lr 1e-4.
+  4. Metrics on the temporal TEST split: torso-normalized PCK@10/20/30/40/50 and
+     MPJPE. Upstream utils/metrics.py calculate_pck(use_torso_norm=True) hardcodes
+     NECK_IDX/PELVIS_IDX = 2, 12 -- a 15-keypoint convention that is WRONG for our
+     17 COCO keypoints (2 = right_eye, 12 = right_hip). We therefore reimplement the
+     identical math (per-frame norm distance, clamp min 0.01, mean over all
+     keypoints x frames) with torso = ||l_shoulder(5) - l_hip(11)||.
+     Also reported: prediction std across test frames (constant-pose detector;
+     must be > 0) and the mean-pose-predictor baseline (train-split mean pose
+     evaluated on test -- the honesty bar).
+
+Usage (on ruvultra):

+"""Configurable compact variants of the WiFlow-STD pose model (ADR-152 efficiency sweep).
+
+This is a parameterized copy of upstream models/{pose_model,tcn,convnet,attention}.py
+(DY2434/WiFlow @ 06899d29, Apache-2.0). upstream/ is NOT modified. Deviations from
+upstream, all forced by shrinking channels and documented per variant in run_sweep.py:
+
+1. TCN grouped-conv groups: upstream hardcodes groups=20, which does not divide
+   the compact channel counts (e.g. 270, 135, 85). Rule here:
+   - groups_mode='gcd20': per-conv groups = gcd(channels, 20)  (== 20 wherever
+     upstream's choice is valid, incl. the 540-ch input conv; falls back to the
+     largest common divisor with 20 otherwise).
+   - groups_mode='depthwise': groups = channels (tiny variant only).
+2. Conv2d downsampling strides: upstream uses 4 stride-(1,2) blocks because
+   240/2^4 = 15 == n_keypoints. With smaller TCN output widths that would leave
+   <15 rows and AdaptiveAvgPool2d((15,1)) would duplicate rows across keypoints.
+   Rule: halve the width only while the result stays >= 15 (stride-2 blocks
+   first, stride-1 after). Full model: 240 -> 4 halvings = upstream exactly.
+3. input_pw_groups (tiny only): the dense 540->c pointwise + residual downsample
+   in TCN block 1 cost 2*540*c params (a ~117k floor that alone exceeds the
+   tiny <100k budget). tiny groups these two convs (groups=4; 4 | gcd(540, 68)).
+4. Decoder mid-channels: upstream 64->32; here c_last -> max(c_last // 2, 4).

+"""WiFlow-STD compact-variant efficiency sweep (ADR-152) — sequential overnight runner.
+
+Trains compact variants of the upstream WiFlow-STD architecture on the same
+data/split as the full-size reference retraining (seed 42, file-level 70/15/15,
+upstream dataset.py) and evaluates PCK@10..50 + MPJPE on the full test split and
+the corruption-free test subset (file indices < 487).
+
+Training mirrors upstream run.py/train.py defaults except:
+- fp32 only (no fp16 autocast / GradScaler — avoids the BN-poisoning trap
+  documented in RESULTS.md defect 5; data on disk is already cleaned).
+- batch 64 (kept modest: another GPU job may share the 16 GB card tonight).
+- scheduler + early stopping keyed on val MPJPE (upstream early-stops on val MPE
+  with patience 5; same here).
+
+Usage:
+  venv/bin/python sweep/run_sweep.py --dry-run    # param counts only
+  nohup venv/bin/python sweep/run_sweep.py > sweep/sweep.log 2>&1 &
+
+Idempotent: variants already present in sweep/results.jsonl are skipped.
+
+NOTE: deployed to ruvultra (~/wiflow-std-bench/sweep) as a standalone file, so
+it deliberately inlines its helpers. The reference implementations (upstream
+import shim, >1GB np.load mmap patch, key-remap loader, canonical evaluate
+loop) live in benchmarks/wiflow-std/_bench_common.py — keep copies in sync.

+"""ADR-152 edge optimization follow-up: ONNX Runtime STATIC post-training
+quantization (calibration-based QDQ) of the retrained WiFlow-STD model, to
+improve on the dynamic-int8 result (2.44 MB, PCK@20 96.52%, 6.5 ms/win b1).
+
+Static PTQ pre-computes activation ranges from calibration data, so inference
+uses QLinearConv/QDQ kernels instead of dynamic ConvInteger -- typically both
+faster and (with good calibration) closer to fp32 accuracy.
+
+Method:
+  - Calibration set: corruption-free windows drawn ONLY from the seed-42
+    file-level TRAINING split (same split as eval_repro.py; corrupted windows
+    excluded via results/nan_windows_mask.npy | big_windows_mask.npy), chosen
+    with np.random.default_rng(42). Never test windows.
+  - quantize_static, QuantFormat.QDQ, per-channel int8 weights, int8
+    activations; calibration methods MinMax / Entropy / Percentile(99.99);
+    scopes "all" (ORT default op set) vs "conv" (op_types_to_quantize=
+    ["Conv"] -- leaves the attention path, which exports as Einsum/Softmax
+    and elementwise ops, in fp32).
+  - Model is pre-processed first (quant_pre_process: symbolic shape
+    inference + ORT graph optimization, folds BatchNormalization into Conv).
+  - Accuracy: identical protocol to eval_ort_accuracy.py -- the 10,000-window
+    seed-42 subset of the corruption-free test split (PCK@20/50, MPJPE).
+  - Latency: median ms/window at batch 1 (100 runs) and batch 64 (30 runs),
+    3 interleaved repetitions across all variants (fp32 and dynamic-int8
+    sessions included as same-session reference points).
+

+"""ADR-152 efficiency-sweep follow-up: edge pipeline for the TINY compact
+WiFlow-STD variant (56,290 params, results/tiny_best.pth, trained overnight
+2026-06-10/11 -- see RESULTS.md "Efficiency sweep").
+
+Headline question: what does the smallest deployable WiFlow-class model look
+like (KB + ms + PCK)? Reuses the onnx_bench.py / static_ptq_bench.py
+machinery on the tiny checkpoint:
+
+  1. Load tiny_best.pth with remote/sweep/model_compact.py
+     (depthwise TCN groups, input_pw_groups=4, conv [2,4,8,16], attn groups 2).
+  2. Export ONNX: dynamic batch, opset 17, TorchScript exporter (dynamo=False)
+     -- same recipe that worked for the full model; verified at batch 1/2/64.
+     One forced deviation: tiny's stride schedule [2,1,1,1] leaves final_width
+     16, and the TorchScript exporter cannot export AdaptiveAvgPool2d((15,1))
+     when 15 is not a factor of the input height (the full model never hit
+     this -- its width was exactly 15). The adaptive pool over a fixed-size
+     feature map is a fixed linear map, so the export wrapper replaces it with
+     an exact matmul equivalent (PyTorch adaptive-pool bin semantics:
+     bin i averages rows floor(i*H/K)..ceil((i+1)*H/K)); the W axis (20->1,
+     a factor) becomes mean(-1). Exactness is proven by the parity check
+     below, which compares against the ORIGINAL torch model with the real
+     AdaptiveAvgPool2d.
+  3. Torch-vs-ORT parity on the stored fixture input
+     (results/parity_fixture.npz, batch 2, seed 42 -- same 540x20 input layout;
+     reference output recomputed with the tiny torch model). PASS < 1e-4.
+  4. Static QDQ conv-only int8 (quant_pre_process + quantize_static,
+     per-channel QInt8 weights+activations, Percentile(99.99) calibration on
+     512 corruption-free TRAIN-split windows -- the winning recipe and
+     calibration count from static_ptq_bench.py. 512, not "about 500":
+     ORT 1.26's histogram collector np.asarray()'s the per-batch maxima, so
+     the calibration count must be a multiple of the batch size 64 or the
+     ragged last batch crashes it).
+  5. Disk size + CPU latency b1/b64 (3 interleaved reps, median ms/window)
+     for tiny fp32 + tiny int8, with the full-model ONNX fp32 + static-int8
+     sessions interleaved as same-session references.
+  6. Accuracy (PCK@20/50 + MPJPE) on the identical 10k-window seed-42
+     corruption-free test subset for tiny fp32 + tiny int8.
+
+Usage:
+  PYTHONUTF8=1 .venv/Scripts/python.exe tiny_edge_bench.py \
+      [--data-dir <preprocessed_csi_data>] [--subset 10000] [--calib 512]

Setup: XIAO ESP32-C6 → hostapd on Intel AX210, 2.4 GHz ch 6, `ieee80211ax=1`. No firmware change required (`acquire_csi_su=1` was already set); the gate was purely the IDF driver version. Three C6 nodes ran this mode simultaneously with ADR-110 ESP-NOW sync. Requires the issue-#1005 version-guard fix in `c6_sync_espnow.c` to build on v5.5.x. |<br><br>**REPLICATED IN-HOUSE (2026-06-11):** same source + fix, fresh IDF v5.5.2 toolchain, original COM12 board (`20:6e:f1:17:00:84`), AP `ruv.net` (11ax 2.4 GHz): **84% of 1,525 captured frames at 532 B / PPDU 0x01 (HE-SU)**, HT minority 148 B / 0x00. Evidence grade: MEASURED (two independent rigs). |
 | **B2** | "TWT-bounded deterministic CSI cadence (10 ms wake)" | No 11ax AP in range. The TWT setup *call* was exercised live and the graceful fallback path is now correct (A9), but the agreement itself was never accepted. **Validate by associating with an 11ax AP that has TWT Responder=1, then capturing the timestamped CSI cadence vs the wall clock.** |

Result identical: 3× candidate, 0× "stepping down". So 2.4 GHz radio coex was NOT the cause. <br><br>**Current leading hypothesis**: OpenThread (CONFIG_OPENTHREAD_ENABLED=y) owns the 802.15.4 radio when its stack is initialized — our weak-symbol overrides of `esp_ieee802154_receive_done` / `_transmit_done` may never be called because OpenThread registers strong handlers. Validation in progress: rebuilding with `CONFIG_OPENTHREAD_ENABLED=n` (raw 802.15.4 only, our beacon protocol is private — no need for the Thread stack). If leader election fires under raw-15.4-only, hypothesis confirmed. <br><br>If raw-only also fails, next move is to dump the actual PHY frame bytes via the IEEE 802.15.4 sniffer mode on a 4th board and diagnose at the frame level. |

+
+> **Scope note:** AetherArena is a **standalone, project-agnostic benchmark** for spatial intelligence — open to *any* project, team, or modality, not a RuView-branded board. RuView contributes the initial scoring harness and enters as one baseline among others; it gets no special treatment. This ADR lives in the RuView repo only because RuView is donating the seed harness — the benchmark itself is independent.

+
+---
+
+## 1. Context
+
+### 1.1 The Gap
+
+RuView has a mature, deterministic evaluation surface but **no public face for it**. Two assets already exist:
+
+1. **A grading harness.** `wifi-densepose-train/src/ruview_metrics.rs` rolls pose (PCK@0.2 / OKS / torso jitter / p95 error), tracking (MOTA / ID-switches / fragmentation), and vitals (breathing/heartbeat BPM error + SNR) into a `RuViewAcceptanceResult` with a `RuViewTier` (`Fail` / `Bronze` / `Silver` / `Gold`). ADR-145's `src/ablation.rs` extends this with presence accuracy, localization error, FP/FN, latency p50/p95/p99, a privacy-leakage score ∈ `[0,1]`, and cross-room degradation, under a determinism binding inherited from the ADR-011 proof harness.
+
+2. **A determinism substrate.** `proof.rs` (`PROOF_SEED=42`) SHA-256-hashes model outputs against an expected hash, so a scored run is reproducible and tamper-evident.
+
+What is missing is a **public, multi-entrant ranking**. As surveyed in ADR-015 and `docs/research/sota-surveys/sota-wifi-sensing-2025.md`, the WiFi-sensing field has **no hosted live leaderboard** the way vision has COCO/EvalAI — researchers self-report numbers against public *datasets* (MM-Fi, Wi-Pose, Person-in-WiFi, Widar3.0) in papers, with inconsistent splits, metrics, and no privacy or latency accounting. RuView's own pose number (PCK@20 ≈ 2.5% with proxy labels, target 35%+ per ADR-079) is currently self-reported on a private validation set and is not comparable to the MM-Fi SOTA (MultiFormer 0.7225).
+
+### 1.2 The Opportunity
+
+The harness that already gates RuView releases is exactly the engine a community leaderboard needs: a single, deterministic, privacy- and latency-aware scoring function. Publishing it as an open leaderboard:
+
+- Establishes **AetherArena as the field's standard yardstick** for spatial intelligence, with RuView's `RuViewTier` + ADR-145 metric set contributed as its initial basis (pose + tracking + vitals + **privacy-leakage** + latency + determinism — a combination no existing benchmark scores). The standard is AA's; RuView donates the seed.
+- Draws **any project, framework, or modality** to submit and rank — a cross-project community flywheel, not a RuView-only one (RuView's `wifi-densepose-pretrained` is merely the first baseline).
+- Forces the harness to harden: a public, neutral scorer must be reproducible by strangers, resistant to gaming, and runnable on a fixed held-out split nobody can train on.
+
+### 1.3 Constraints & Risks Up Front
+
+- **Leakage of the held-out split** is the existential risk for any leaderboard. The eval data must be private; submitters provide a model, not predictions on data they hold.
+- **Compute cost.** Scoring a submission runs inference over the eval set; an HF Space on free CPU may be too slow for the Candle/`tch` pipeline. Tiering of compute (CPU smoke vs GPU full score) is required.
+- **Privacy / consent of the eval data.** MM-Fi and Wi-Pose carry their own licenses; we can host *derived* CSI features and scores but must respect redistribution terms (ADR-015 already tracks this).
+- **Trust.** A `RuViewTier` badge is only meaningful if the scoring is deterministic and the leaderboard cannot be silently edited — the ADR-011 proof hash and a signed results ledger address this.
+
+---
+
+## 2. Decision
+
+**Create AetherArena ("AA") — the official, project-agnostic Spatial-Intelligence Benchmark: a public, open-entry leaderboard for camera-free spatial perception (pose, presence, occupancy, tracking, vitals) as a standalone repo `ruvnet/aether-arena` paired with a Hugging Face Space. The scoring engine is seeded by RuView's existing `ruview_metrics` + ADR-145 ablation harness, contributed as a neutral scorer; v0 evaluates against a private MM-Fi held-out split.**
+
+AA is **not a RuView leaderboard**. It is the field's missing standard yardstick for spatial intelligence — open to any team, framework, or sensing modality. The RF medium is the v0 input and RuView donates the seed harness + a baseline entry, but the benchmark is independent and RuView is scored like every other entrant. The metric surface — pose, presence, tracking, occupancy/world-model, latency, determinism, and later privacy — is modality-agnostic, leaving room to grow to mmWave / UWB / radar / lidar / multimodal entrants and other projects.
+
+The leaderboard does **not** fork or re-implement the scoring logic. It is a thin orchestration + presentation layer over the published `wifi-densepose-cli` scorer, so the public number a model earns is identical to the number RuView uses internally to gate releases. **This makes the leaderboard governance, not marketing.**
+
+The whole design reduces to a precise four-part structure:
+
+> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
+
+- **Public leaderboard** — anyone can see the ranking and submit.
+- **Private evaluation split** — the held-out data is never published; it cannot be trained on or overfit.
+- **Open scorer** — the scoring code is the published `wifi-densepose-cli`; a stranger can rerun it locally on a public *smoke* split and reproduce the logic.
+- **Signed results** — every score is an append-only, signed ledger row with a determinism proof hash; ranks cannot be silently edited.
+
+### 2.1 Name — DECIDED: `ruvnet/aether-arena` ("AA")
+
+**Locked.** Canonical repo + HF Space: **`ruvnet/aether-arena`**, branded **AetherArena** with the short form **"AA"**.
+
+- **"Aether"** = the classical all-pervading medium — fitting for RF/ambient spatial perception, and broader than "Ether"/CSI/WiFi so the benchmark can grow to mmWave, UWB, and multimodal spatial-intelligence entrants without a rename.
+- **"Arena"** = open competitive entry.
+- HF Space title: *AetherArena (AA) — the spatial-intelligence benchmark for RF perception.*
+- `ruvnet/wifi-densepose-leaderboard` is kept only as a discoverability/topic alias that redirects to AA.
+
+(Rejected: `csi-arena` — jargon; `rf-bench` — generic/collision; `wifi-densepose-leaderboard` as the primary — ties the brand to one capability.)

+                           one signed row per submission)
+```
+
+1. **Submission contract.** A submitter pushes a model artifact (`model.safetensors` / `.rvf` / LoRA adapter) plus a `ruview-arena.toml` manifest declaring: input feature set (which ADR-145 `FeatureSet` it consumes — F0 CSI / F1 CIR / F2 Doppler / F3 BFLD), tensor I/O contract, license, and optional category (pose / presence / tracking / vitals / multi-task).
+2. **Scoring.** The Space runs the **published `wifi-densepose-cli`** in a pinned container against a **private held-out split** of MM-Fi / Wi-Pose (and RuView's own paired-capture set per ADR-079). Output is the existing `RuViewAcceptanceResult` + the ADR-145 scalar set, plus the ADR-011 SHA-256 reproducibility hash.
+3. **Ledger.** Each scored submission appends **one signed row** to an append-only HF dataset (`ruvnet/aether-arena-results`, Parquet): `{submitter, model_ref, category, feature_set, tier, pck20, oks, mota, vitals_bpm_err, latency_p50, latency_p95, privacy_leakage, cross_room_deg, proof_sha256, scored_at, harness_version}`. Append-only + signed = no silent edits.
+4. **Presentation.** Gradio leaderboard with category tabs (Pose / Presence / Tracking / Vitals / Edge-latency / **Privacy**), `RuViewTier` badges, and a "privacy-respecting" filter (leakage ≤ threshold) — the differentiator no other WiFi benchmark has.
+
+### 2.2.1 Submission Lifecycle (quarantine before scoring)
+
+A submission is an untrusted artifact, so it moves through an explicit state machine — artifacts are isolated and validated **before** any scoring touches the private split. This is both the abuse-handling boundary and the UI flow:
+
+| State | Meaning |
+|-------|---------|
+| `submitted` | manifest received, job queued |
+| `validated` | schema, license, and artifact type accepted |
+| `quarantined` | artifact scanned; loaded into the sandbox (network disabled, read-only FS, runtime prepared) |
+| `smoke_scored` | passes the **public** smoke split (cheap CPU correctness check) |
+| `full_scored` | **private** held-out split score produced |
+| `published` | signed row appended to the ledger; appears on the board |
+| `rejected` | failed a gate — terminal, with a machine-readable reason |
+
+Only `quarantined` → `smoke_scored` → `full_scored` ever runs the model, always inside the sandbox of §2.4. A failure at any gate transitions to `rejected` with a reason rather than silently dropping.
+
+### 2.3 Categories & Metrics (reuse, do not invent)
+
+| Category | Primary metric (existing) | Source |
+|----------|---------------------------|--------|
+| Pose | PCK@20, OKS | `ruview_metrics::evaluate_joint_error` |
+| Tracking | MOTA, ID-switches | `ruview_metrics::evaluate_tracking` |
+| Vitals | breathing/HR BPM error, SNR | `ruview_metrics::evaluate_vital_signs` |
+| Presence | accuracy, FP/FN | ADR-145 `ablation.rs` |
+| Edge latency | p50 / p95 / p99 ms | ADR-145 `LatencyProfile` |
+| **Privacy** | leakage score ∈ `[0,1]` (membership-inference) | ADR-145 §10 |
+| Cross-room | degradation ratio | ADR-027 / ADR-145 |
+| Overall | `RuViewTier` Bronze/Silver/Gold + `arena_score` (§2.5) | `determine_tier()` |
+
+### 2.3.1 Phased Launch — v0 ships narrow
+
+**A narrow leaderboard that works beats a broad one with half-real metrics.** v0 ranks only categories whose metric is fully implemented and reproducible-by-strangers today; the rest are visible as **"coming soon" / gated** and are **not ranked** until their metric is real.
+
+| Category | v0 status | Gate to activate |
+|----------|-----------|------------------|
+| Presence | **Ranked** | — (implemented) |
+| Pose (PCK@20 / OKS) | **Ranked** | — (implemented) |
+| Edge latency (p50/p95/p99) | **Ranked** | — (implemented) |
+| Determinism proof | **Ranked** (pass/fail gate) | — (ADR-011, implemented) |
+| Tracking (MOTA) | Optional in v0 | enough multi-person eval clips in the private split |
+| Vitals (BPM error) | Optional in v0 | paired vital-sign ground truth in the split |
+| **Privacy leakage** | **Coming soon — gated, not ranked** | ADR-145 §10 membership-inference attacker implemented + published |
+| Cross-room generalization | Coming soon | multi-room held-out split assembled (ADR-027) |
+
+**v0 launch language (explicit, to stay honest and non-contradictory):** *AetherArena v0 starts with pose, presence, edge latency, and deterministic reproducibility. Tracking and vitals are activated when sufficient ground-truth clips are available. Privacy-leakage and cross-room generalization remain gated until their evaluation attacks and splits are implemented and published.* Shipping a "privacy leaderboard" claim before the attacker exists would be an easy and deserved attack on our credibility.
+
+### 2.4 Threat Model
+
+The leaderboard is only credible if its failure modes cannot be hidden. Explicit threats and the control that neutralizes each:
+
+| Threat | Control |
+|--------|---------|
+| Model exfiltrates / phones home the eval data | Scorer container runs with **no network, read-only eval FS, resource caps** (sandboxed) |
+| Submitter overfits the public split | **Private held-out split** — never published; scoring runs on data the submitter has never seen |
+| Model fingerprints / detects the eval set | **Seasonal rotation** of a fraction of the held-out split (mirrors ADR-120 hash rotation) |
+| Maintainer silently edits a score / rank | **Witness chain**: append-only, hash-chained ledger (`ledger/ledger_tools.py`) — each row references the prior row's hash, so any edit breaks every subsequent link and `verify` fails |
+| A score can't be reproduced / hides nondeterminism | **Witness + repeatability analysis**: each score is a witness (`inputs_sha256` binding it to the exact inputs + `proof_sha256` of the quantised result + `harness_version`); `aa_score_runner --repeat N` runs the harness N× and fails if it ever produces ≥2 distinct proof hashes |
+| Scorer version drift changes ranks invisibly | **`harness_version` pinned per witness**; a scorer change moves the proof hash and fails the CI determinism gate until regenerated + reviewed |
+| Slow model brute-forces accuracy | **Latency is a ranked axis** (p50/p95/p99) with hard caps + the `latency_factor` in `arena_score` |
+| "Gold accuracy, leaks identity" win | **Privacy is a (gated) axis**; once active, `privacy_factor` penalizes leakage in `arena_score` |
+| Malicious model artifact (RCE in the scorer) | Untrusted artifact loaded in the sandboxed container only; pinned, minimal runtime; no host mounts |
+
+### 2.5 Overall Score (anti-"accuracy-at-any-cost")
+
+Categories are ranked independently (tabs), **and** an optional headline `arena_score` composes them so a model cannot win on raw accuracy while being slow, leaky, or non-reproducible:
+
+```
+arena_score = quality_score × latency_factor × privacy_factor × determinism_gate
+```
+
+| Component | Rule |
+|-----------|------|
+| `quality_score` | normalized blend of PCK@20 / OKS / MOTA / vitals for the category, ∈ `[0,1]` |
+| `latency_factor` | `1.0` if p95 ≤ target; decays smoothly above target (edge viability) |
+| `privacy_factor` | `1.0 − privacy_leakage` once the Privacy axis is active; **fixed at `1.0` in v0** (privacy gated/unranked) |
+| `determinism_gate` | `1.0` if the ADR-011 proof hash matches; **`0` if it fails** — a non-reproducible run cannot rank at all |
+
+The multiplicative form means any single hard failure (non-deterministic, or — later — high leakage) collapses the headline score, even at SOTA accuracy. In v0, `privacy_factor` is pinned to `1.0` so the headline number is honest about what is actually measured.
+
+**`arena_score` is a gate, not the only headline.** Multiplicative composites are great for gating but can hide *why* a model lost, and invite "your formula is biased" arguments. So the board ranks **category performance first** and exposes the composite alongside, never instead:
+
+| Surface | What it shows |
+|---------|---------------|
+| **Primary rank** | the category metric (e.g. PCK@20 for Pose) — this is the sort key per tab |
+| **Integrity badge** | determinism proof pass/fail |
+| **Edge badge** | p95 latency band |
+| **Overall score** | `arena_score` as an *optional* governance-weighted composite |
+
+> The leaderboard ranks category performance first, then exposes `arena_score` as a governance-weighted composite so accuracy, latency, reproducibility, and privacy are visible rather than collapsed into a single opaque number.
+
+### 2.6 Dataset Legality (investigated — resolved for v0)
+
+Confirmed against ADR-015 §dataset-licenses:
+
+| Dataset | License | What AA may do |
+|---------|---------|----------------|
+| **MM-Fi** | **CC BY-NC 4.0** | ✅ v0 eval source. Non-commercial use + derivatives **permitted with attribution**. AA may host *derived* CSI features and scores; raw frames stay in the private split. AA must be operated **non-commercially** and carry MM-Fi attribution. |
+| **Wi-Pose** | **"Research use"** (no clean redistribution grant) | ⚠️ **Not hosted.** Pulled privately into the scorer only, never redistributed; or deferred until terms are clarified with the authors. **Dropped from v0.** |
+| Person-in-WiFi-3D | semi-public access | Future candidate (post-v0), pending access terms. |
+
+**v0 decision:** evaluate on a **private MM-Fi held-out split only** (CC BY-NC, attributed, non-commercial; expose only license-permitted derived features). Wi-Pose is removed from v0 and revisited if/when redistribution is cleared. This keeps the existential "can we even host this" risk at zero for launch.
+
+> **Non-commercial caveat to watch:** CC BY-NC means AA itself, and the eval-data use, must remain non-commercial. Because AA also showcases the (commercial) RuView appliance, keep AA legally distinct and non-commercial, or seek an MM-Fi commercial grant before any paid tier. Flagged for the maintainer.
+
+### 2.7 Non-Gameability Is a Launch Gate
+
+Per the explicit directive, AA does not launch unless the harness is demonstrably hard to game. The controls (private split §2.4, seasonal rotation §2.4, model-not-prediction submission §2.2, sandbox §2.4, pinned `harness_version` §2.4, signed append-only ledger §2.3-§2.4, multiplicative `arena_score` §2.5, `determinism_gate=0` on proof-hash failure §2.5) are **not optional hardening — they are acceptance criteria** (see §7). A v0 that can be topped by overfitting a public split, a non-reproducible run, or a silently edited row is, by definition, not ready.
+
+### 2.8 Neutrality & Governance (because it's "official" and cross-project)
+
+The hardest credibility problem for an *official* benchmark seeded by one entrant: **"RuView built the scorer, so of course RuView wins."** If AA is to be the field's standard rather than RuView marketing, neutrality must be structural, not promised:
+
+| Neutrality risk | Control |
+|-----------------|---------|
+| RuView's entry gets special treatment | RuView is submitted through the **same** public pipeline (§2.2.1) and scored by the **same** pinned scorer as everyone else; its rows carry the same proof hash and are independently re-runnable on the smoke split. |
+| RuView tunes the metric to favor its models | The scorer is **open and versioned**; any metric change is a public `harness_version` bump that **re-scores all entries**, not just new ones. Metric changes go through a public changelog. |
+| "Official" is self-declared | AA is positioned as a **neutral commons**: separate repo/Space identity, contribution guide, and an explicit invitation for other projects + dataset authors to co-own splits and metrics. RuView is the *donor of the seed harness*, not the owner of the standard. |
+| Benchmark used as RuView ad | Keep AA legally + brand-distinct (ties into the CC BY-NC non-commercial caveat, §2.6); the README leads with the standard, not the product. |
+| Single-vendor capture | Roadmap to a multi-org steering/eval committee once ≥N external projects enter; split rotation + metric proposals are public. |
+
+The test for neutrality is the same as §7's acceptance test: a stranger from *another project* can submit, reproduce the score, and see that RuView's own entries were scored by the identical, open, pinned path.
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+- A real, comparable public number for RuView (and everyone else) on MM-Fi / Wi-Pose, scored by a privacy- and latency-aware harness no other WiFi benchmark offers.
+- Community flywheel: external models/adapters get ranked, feeding `ruvnet/wifi-densepose-pretrained`.
+- Forces the harness to be reproducible-by-strangers, which strengthens internal release gating too.
+
+### 3.2 Negative / Costs
+- **New repo + HF Space to maintain**, incl. a scoring container and queue. Ongoing compute cost (mitigate: CPU smoke-score on submit, batched GPU full-score on a schedule).
+- **Dataset licensing** must be cleared for hosting derived MM-Fi / Wi-Pose features (ADR-015 owns this; may require contacting dataset authors).
+- **Abuse surface** (malicious model artifacts run in the scorer) — must sandbox the container (no network, read-only eval data, resource caps).
+
+### 3.3 Neutral
+- The scoring logic stays in `wifi-densepose-train`/`-cli`; the leaderboard is presentation only, so it does not bloat the core workspace.
+
+---
+
+## 4. Alternatives Considered
+
+1. **Submit RuView to existing venues only (MM-Fi GitHub, Papers-with-Code).** Lower effort, but no privacy/latency axes, no live entry, and RuView doesn't own the standard. *Complementary, not exclusive — we should still post MM-Fi numbers.*
+2. **A static numbers page in the RuView README.** Zero infra, but not multi-entrant and not a leaderboard.
+3. **EvalAI / Kaggle competition.** Stronger anti-gaming infra, but heavyweight, time-boxed, and off-brand vs an always-open HF Space next to the model.
+
+---
+
+## 5. Open Questions
+
+1. **Eval data hosting** — can we redistribute derived MM-Fi / Wi-Pose CSI features under their licenses, or must scoring pull the raw datasets the submitter cannot see? (Owner: ADR-015 follow-up.)
+2. **Compute budget** — free HF CPU Space, ZeroGPU, or a self-hosted scorer on the GCloud A100/L4 fleet (`cognitum-20260110`)?
+3. **Name lock** — confirm `aether-arena` vs `wifi-densepose-leaderboard`.
+4. **Season cadence** — does the held-out split rotate monthly, and do we keep an all-time + per-season board?
+5. **Privacy-leakage attack** — ship the membership-inference attacker (ADR-145 §10 is currently a *defined-but-unimplemented* metric) before launch, or launch with privacy as a "coming soon" axis?
+
+---
+
+## 6. Implementation Sketch (if accepted)
+
+- **P1** — Stand up `ruvnet/aether-arena` repo + skeleton Gradio HF Space; define `ruview-arena.toml` submission contract; publish a **public smoke split** a stranger can score locally.
+- **P2** — Containerize `wifi-densepose-cli score` as the pinned, sandboxed scorer (no network, read-only FS, caps); wire the signed append-only Parquet ledger + `determinism_gate`.
+- **P3 — v0 LAUNCH (narrow).** Clear + load the private MM-Fi / Wi-Pose held-out split; activate **Presence, Pose, Edge-latency, Determinism** categories; seed the board with RuView's own `wifi-densepose-pretrained` baseline (honest current PCK@20). Tracking/Vitals optional. Privacy + Cross-room shown as **gated / coming soon**.
+- **P4** — *(post-launch, gated)* Implement the ADR-145 §10 privacy-leakage membership-inference attacker; only then activate + rank the **Privacy** category and switch `privacy_factor` on in `arena_score`.
+- **P5** — Assemble the multi-room split → activate **Cross-room**. Submit RuView's MM-Fi number to Papers-with-Code in parallel (alternative #1).
+
+## 7. Acceptance Test (definition of done for v0)
+
+v0 launches **only when a stranger can:**
+
+1. **Submit** a model (artifact + `ruview-arena.toml`) through the Space with no insider help,
+2. **Get a deterministic score** back (same model + same harness version → same numbers),
+3. **See the signed row** appended to the public results ledger,
+4. **Rerun the scorer locally** on the public *smoke* split and reproduce the logic, and
+5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from the docs alone.
+
+If any of these five fails, v0 is not ready.
+
+## 8. Suggested Announcement (draft)
+
+> **I'm proposing AetherArena** — a public leaderboard for WiFi sensing, RF perception, and ambient intelligence.
+>
+> The problem with this field is not just model quality. It is *measurement* quality. Most WiFi-sensing work reports numbers against datasets with inconsistent splits, inconsistent metrics, and almost no accounting for latency, privacy leakage, reproducibility, or edge viability.
+>
+> AetherArena fixes that. Models are submitted, scored in a pinned sandboxed container against **private** held-out MM-Fi and Wi-Pose splits, and written to a **signed append-only** results ledger. The scoring engine reuses the same RuView harness we use internally: pose, presence, tracking, vitals, latency, cross-room degradation, deterministic proof hashes — and, once its attacker ships, privacy leakage.
+>
+> The goal is not to make RuView look good. The goal is to make the *category* measurable. If ambient intelligence is going to move from demos to infrastructure, it needs public numbers, reproducible commands, private eval splits, and failure modes that cannot be hidden.

+> plus a `SotaComparison` against Wi2SAR. This ADR defines **how we evaluate the swarm
+> rigorously** — what metrics, what statistics, what baselines, and an honest account
+> of which external leaderboards do and do not apply.
+
+---
+
+## 1. Context
+
+ADR-148's `ruview-swarm` reports performance via five `criterion` micro-benchmarks and a
+single `SotaComparison` (localization 1.732 m vs Wi2SAR 5 m; coverage ~223 s vs 810 s).
+These numbers are **internally valid but insufficient as scientific claims**:
+
+- The criterion figures (3.3 µs MARL inference, 43 µs RRT-APF, 54 ns fusion, 248 µs PPO
+  step) measure **wall-clock latency**, not policy quality or coverage/localization quality.
+- The 1.732 m localization comes from a **single synthetic geometry** (3 drones at 120°
+  around a known point), not a distribution of victim positions under realistic noise.
+- The 223 s coverage is an **analytic estimate** (`estimate_coverage_time_secs()`), not an
+  episode rollout.
+- All numbers are **single-run point estimates**. The MARL reproducibility literature
+  (Henderson 2018; Agarwal 2021; Gorsane 2022) shows single/few-seed point estimates
+  routinely flip algorithm rankings and overstate gains.
+
+We need a defined, reproducible evaluation methodology before any "beats SOTA" claim can
+survive external review, and an honest position on external leaderboards.
+
+---
+
+## 2. Decision
+
+Adopt a two-tier evaluation methodology:
+
+1. **Micro-benchmarks (criterion)** — keep for compute-latency regression gating only.
+   Explicitly labeled as latency, never as quality.
+2. **Domain evaluation harness** — a seeded, multi-run, statistically-reported harness
+   producing SAR metrics (localization CEP, coverage, detection rate) and MARL metrics
+   (IQM return, probability-of-improvement) over **≥10 seeds with 95% stratified-bootstrap
+   confidence intervals**, against **≥3 baselines**, following the Agarwal/Gorsane standard.
+
+Do **not** claim leaderboard standing — no public leaderboard accepts drone-swarm CSI-SAR
+submissions. Comparisons to Wi2SAR are **paper-to-paper**, labeled as such, acknowledging
+the sensing-modality difference (RSS bearing vs CSI multi-view fusion).
+
+---
+
+## 3. External Leaderboard Landscape — Honest Assessment
+
+**There is no public, externally-administered leaderboard that accepts a drone-swarm,
+CSI-based, multi-view SAR system.** This is a research niche; comparison is paper-to-paper.
+The adjacent options and their fit:
+
+| Benchmark / Leaderboard | Domain | Live submission? | Fit for ruview-swarm |
+|-------------------------|--------|------------------|----------------------|
+| **Wi2SAR** (arxiv 2604.09115) | Drone WiFi SAR | No (paper) | **Direct baseline** — paper-to-paper only; RSS bearing ≠ CSI fusion |
+| **MARL4DRP** (Springer 2023) | Drone routing MARL | No | Closest drone-MARL benchmark; would need a routing→coverage adapter |
+| **CSI-Bench** (NeurIPS 2025) | Static WiFi sensing | Splits + paper baselines | Adjacent (localization task) but no moving-sensor/multi-view fusion |
+| **SMAC / SMACv2** | StarCraft cooperative MARL | No live LB | Structural analogy (CTDE) only; combat task, not coverage |
+| **PettingZoo MPE** (Simple Spread) | 2D cooperative particles | No | Cheap MARL **correctness check**, no physics/CSI |
+| **Melting Pot** | Social-dynamics MARL | Closed (NeurIPS '24) | Not applicable |
+| **MAMuJoCo / Hanabi / GRF / Overcooked** | Various cooperative MARL | No live LB | Not applicable |
+| **OmniDrones / gym-pybullet-drones / Pegasus** | Drone-control sim platforms | No (platforms) | **Training infrastructure**, not leaderboards; no CSI layer |
+
+**Conclusion:** We will (a) keep Wi2SAR as the cited paper baseline, (b) optionally build a
+MARL4DRP/MPE adapter to post a recognized cooperative-MARL number (tangential to SAR), and
+(c) **not** represent any internal number as a leaderboard placement.
+
+---
+
+## 4. Evaluation Metrics
+
+### 4.1 SAR Domain Metrics (primary — comparable to Wi2SAR)
+
+| Metric | Definition | Reporting |
+|--------|-----------|-----------|
+| Localization CEP50 | Median horizontal error, fused victim position vs ground truth | m, 95% CI |
+| Localization CEP95 | 95th-percentile horizontal error | m |
+| **GDOP** | Geometric Dilution of Precision of the contributing-drone constellation at detection time | dimensionless (tracked per detection) |
+| Coverage rate @ T | Fraction of area scanned ≥1× within T=240 s | %, 95% CI |
+| Coverage time to 95% | Time to scan 95% of bounded area | s, mean ± CI |
+| Time-to-first-detection | Mission start → first confident detection (conf > 0.85) | s, 95% CI |
+| Detection rate | P(detected \| victim present) per mission | %, 95% CI |
+| False-alarm rate | P(confident detection \| no victim) | %, 95% CI |
+| Collision rate | Collisions (d < 1.5 m) per mission | count/mission |
+| Overlap ratio | Fraction of path re-covering scanned cells | % |
+
+### 4.2 MARL Policy-Quality Metrics
+
+| Metric | Definition |
+|--------|-----------|
+| IQM episodic return | Interquartile mean over 10 seeds × 50 eval episodes (Agarwal 2021) |
+| Probability of improvement | P(MAPPO return > IPPO return) on a random episode |
+| Optimality gap | Expected gap to a defined reference performance |
+| Performance profile | Fraction of (seed, episode) with localization error < τ, plotted vs τ ∈ [0,10] m |
+| Sample efficiency | Return vs training steps (curve, not point) |
+
+### 4.3 Micro-benchmarks (criterion — latency only)
+
+Retained from ADR-148, **labeled as compute latency, not quality**:
+`marl_actor_inference` 3.3 µs · `rrt_apf_100iter` 43 µs · `multiview_fusion_3drones` 54 ns ·
+`demo_coverage_estimate` 100 ps · `ppo_update_64transitions` 248 µs. Purpose: prove the
+control loop has no compute bottleneck (all ≪ the 10 ms / 100 Hz budget) and gate
+performance regressions. They are **not** evidence of policy or localization quality.
+
+---
+
+## 5. Statistical Protocol (Agarwal 2021 / Gorsane 2022)
+
+| Requirement | Standard adopted |
+|-------------|------------------|
+| Seeds per condition | **≥10** training runs from distinct seeds |
+| Evaluation episodes | 50 fixed, versioned episodes per trained policy (10 victim layouts × 5 CSI-noise levels) |
+| Aggregate metric | **IQM** (not mean, not median) + performance profiles |
+| Confidence intervals | **95% stratified bootstrap**, 1,000 resamples |
+| Baselines (≥3) | Random walk (lower bound), Boustrophedon+manual-triangulation (heuristic), IPPO (no shared critic) |
+| Reproducibility | Versioned YAML config (drone count, area, victims, CSI σ amplitude / κ phase, wind, packet loss) + all seeds committed with results |
+
+Rationale: Henderson et al. (2018) found ≤5-seed point estimates flip rankings; Agarwal et
+al. (2021, NeurIPS Outstanding Paper) show IQM needs ~10 runs for the statistical power that
+the median needs ~200 runs for; Gorsane et al. (2022) made ≥10 seeds + IQM + stratified CIs
+the cooperative-MARL standard. `rliable` (google-research/rliable) is the reference impl.
+
+---
+
+## 6. Reproducibility Harness (`evals/`)
+
+A new evaluation harness (separate from criterion micro-benchmarks):
+
+1. **Seeded episodes** — every episode, noise perturbation, and training run seeded from a
+   versioned config; seeds committed with results (no `Date.now()`/unseeded RNG).
+2. **Per-episode logging** — coverage %, localization error, GDOP, time-to-first-detection,
+   collisions, detection binary → JSONL (reuses the ADR-148 telemetry schema).
+3. **Aggregation** — IQM ± 95% stratified-bootstrap CI across the 10-seed × 50-episode matrix.
+4. **Baseline sweep** — random / boustrophedon-heuristic / IPPO / MAPPO, so
+   probability-of-improvement and performance profiles are computable.
+5. **Output** — committed `evals/RESULTS.md`: a reproducible internal leaderboard ranking
+   our 6 flight patterns × learning patterns on the SAR metrics, plus the Wi2SAR paper row.
+
+This `RESULTS.md` is the **real, defensible "leaderboard" for this system** — patterns ranked
+against each other and the cited baseline, reproducibly, with CIs.
+
+### 6.1 Dual-stage pipeline (compute-cost mitigation)
+
+The full matrix is **10 seeds × 50 episodes × ≥4 conditions = ≥2,000 rollouts per policy**.
+Running each rollout against the OccWorld 3D prior (ADR-147, ~375 ms/inference) would melt
+the L4 / RTX 5080 budget. Split evaluation into two stages:
+
+- **Stage 1 — Kinematic (fast, full matrix).** Stripped vector environment; OccWorld paths
+  pre-cached or treated as static analytical volumes. Produces episodic **return, IQM,
+  sample-efficiency curves, coverage %, GDOP, localization error** over the full 10-seed matrix.
+- **Stage 2 — High-fidelity physics (sub-sampled).** Take the **3 median seeds** (by Stage-1
+  IQM) into Gazebo + PX4 SITL with full CSI phase/amplitude noise. Extracts **false-alarm
+  rate** and **collision rate** under realistic dynamics (heading-rate limits, APF repulsion,
+  motor response) that the kinematic sim omits.
+
+Stage 1 is CI-runnable today; Stage 2 requires the Gazebo/PX4 SITL bring-up (follow-on).
+
+### 6.2 Noise sweep (coherence-gate threshold)
+
+The config generator systematically varies the two CSI noise parameters:
+- **σ** — Gaussian amplitude noise (CSI magnitude)
+- **κ** — von Mises phase concentration (lower κ = noisier phase)
+
+Sweeping (σ, κ) isolates the exact environmental threshold where `CrossViewpointAttention`
+(ADR-016) drops out of its coherence gate (`coherence_gate.rs` Accept → PredictOnly/Reject,
+ADR-135). This finds the operating envelope, not just a single-point accuracy.
+
+### 6.3 GDOP tracking
+
+Localization accuracy is meaningless without the constellation geometry that produced it.
+The harness records **GDOP** per detection: 3 drones in a ~120° constellation give the
+√3 ≈ 1.73× CRLB improvement; 3 **collinear** drones degrade toward the single-view
+Cramer-Rao limit (~2.9 m). Reporting localization error **stratified by GDOP band** prevents
+the headline number from being a best-case geometric artifact.
+
+---
+
+## 7. Evidence Grading of Current ADR-148 Numbers
+
+| Claim | Grade | Why |
+|-------|-------|-----|
+| criterion latencies (3.3 µs / 43 µs / 54 ns / 248 µs) | **High** | Deterministic compute, hardware-specific, reproducible |
+| Wi2SAR baseline (5 m, 160k m²/13.5 min) | **High** | Published field trial, open source |
+| 1.732 m 3-view localization | **Low–Medium** | Single synthetic geometry; no noise distribution; CRLB predicts ~2.9 m for N=3 |
+| 223 s 4-drone coverage | **Low** | Analytic estimate, not an episode rollout |
+| "beats SOTA" | **Directional only** | Valid as paper-to-paper direction; not leaderboard, not multi-seed |
+
+The √N multi-view scaling claim is theoretically sound (CRLB: σ ∝ 1/√(N·SNR); N=3 → √3 ≈
+1.73× improvement), but the measured 1.732 m must be reproduced over a victim-position and
+noise distribution before it is defensible.
+
+---
+
+## 8. Consequences
+
+### Positive
+- Converts scattered numbers into a reproducible, statistically-honest evaluation.
+- The `RESULTS.md` internal leaderboard ranks the 6 flight × 4 learning patterns fairly.
+- Aligns with the recognized MARL evaluation standard (IQM + stratified CIs + ≥10 seeds).
+- Honest external-leaderboard position avoids overclaiming.
+
+### Costs / Risks
+- ≥10 seeds × 50 episodes × N patterns × N baselines is a real compute cost — this is where
+  the ADR-148 GCP L4 / local RTX 5080 training budget is actually spent.
+- Requires the MARL policy to be **trained to convergence** first (the ADR-148 5-episode CPU
+  run shows decreasing value_loss, not convergence).
+- Coverage/localization must move from analytic estimate / synthetic geometry to **episode
+  rollouts under realistic CSI noise** before headline numbers are republished.
+
+### Open issues → follow-on work
+1. Train MAPPO/IPPO to convergence (M4 follow-on) before running the eval harness.
+2. Build the seeded `evals/` harness + `RESULTS.md` generator.
+3. Optional: MARL4DRP or MPE Simple-Spread adapter for a recognized cooperative-MARL number.
+4. Re-state ADR-148 §14 headline numbers with CIs once the harness has run.

+# ADR-150: RuView RF Foundation Encoder — pose-preserving, subject/room/device-invariant CSI embedding
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-30 |
+| **Deciders** | ruv |
+| **Codebase target** | New `wifi-densepose-rfencoder` (or `nn/src/rf_foundation.rs`) + training in `wifi-densepose-train`; consumed by the MM-Fi pose head and the AetherArena Generalization Track (ADR-149) |
+| **Relates to** | ADR-024 (Contrastive CSI Embedding / AETHER), ADR-027 (Cross-Environment Domain Generalization / MERIDIAN), ADR-134 (CIR), ADR-135 (calibration + coherence gate), ADR-145 (Ablation/Eval Harness), ADR-149 (AetherArena benchmark) |
+
+---
+
+## 1. Context
+
+AetherArena now has a published, metric- and protocol-matched MM-Fi result: **81.63% torso-PCK@20 in-domain (random_split), exceeding MultiFormer's 72.25%** ([#876](https://github.com/ruvnet/RuView/issues/876)). But the **leakage-free cross-subject** number collapses to **~11.6% torso-PCK** (27% under the looser bbox metric). That gap is the real deployment frontier — homes, elder care, festivals, unseen bodies.
+
+Naïve fixes already tested and **failed**: a subject-adversarial (DANN) embedding did not move cross-subject (baseline 27.26% → DANN 27.54% bbox; torso 11.57%). Bigger capacity *hurt* (transformer cross-subject 24.8% < conv 27.3%) — extra parameters overfit seen subjects.
+
+**Conclusion:** a *generic* "better feature vector" will not help. The lever is an embedding trained for the **right invariance** — one that preserves pose while removing subject, room, and device signatures, and that *exposes* channel instability rather than hiding it.
+
+### 1.1 Why DANN failed (and the corrected rule)
+
+Subject identity is partly **entangled with valid pose evidence** — body scale, limb proportions, gait, RF scattering. Blindly erasing subject info also erases information the pose decoder needs. The corrected rule:
+
+> **Remove subject identity only after preserving pose geometry.** Supervised *pose-contrast across subjects* beats naïve adversarial identity removal.
+
+The frontier objective is **not** `same-subject = positive`. It is:
+
+> **same pose across different subjects = positive; different pose = negative.**
+
+## 2. Decision
+
+**Build the RuView RF Foundation Encoder: a self-supervised, pose-preserving, subject/room/device-invariant RF representation for CSI (extensible to CIR, ADR-134, and BFLD).** Positioned as a **platform primitive**, not a benchmark trick.
+
+### 2.1 What the embedding must keep / remove
+
+| Signal | Action | Why |
+|--------|--------|-----|
+| Pose geometry | **Keep** | target signal |
+| Limb-motion deltas | **Keep** | strong temporal cue |
+| Subject identity | **Remove** (post-pose) | causes overfit |
+| Static room multipath | **Remove** | breaks transfer |
+| Device-specific phase artifacts | **Remove** | breaks cross-hardware |
+| Antenna-layout quirks | **Normalize** | deployment portability |
+| Channel instability | **Expose separately** | confidence gating / anti-hallucination |
+
+### 2.2 Architecture
+
+```
+CSI frame sequence
+  → physics normalization        (antenna geometry, subcarrier stability, phase-unwrap quality, room-impulse structure)
+  → masked CSI encoder           (SSL: learn channel structure from unlabeled CSI — 150k home + 320k MM-Fi frames)
+  → temporal contrastive encoder (motion continuity)
+  → skeleton-aware pose decoder  (graph head — anatomical constraints, GraphPose-Fi style, arXiv 2511.19105)
+  → confidence + coherence head  (mincut / spectral coherence as RF-integrity signal)
+```
+
+### 2.3 Training objectives (loss stack)
+
+```
+L_total = L_pose
+        + 0.20 · L_masked_csi          # learn channel structure (unlabeled)
+        + 0.10 · L_temporal_contrast   # motion continuity
+        + 0.20 · L_pose_contrast        # same-pose-across-subjects = positive  ← the frontier
+        + 0.05 · L_subject_decorrelation # remove identity only where it conflicts with pose
+        + 0.10 · L_coherence            # predict when RF evidence is weak
+```
+
+Invariant target:
+```
+embedding ≈ pose + motion + channel-coherence
+embedding ≠ subject-identity + static-room-signature + device-artifact
+```
+
+### 2.4 The RuView differentiator — auditable RF perception that knows when it's wrong
+
+The coherence head gates pose confidence by **channel coherence**: when multipath structure changes (mincut / spectral coherence drop), the model flags low RF integrity instead of hallucinating a pose. This is the **anti-hallucination** component most WiFi-pose papers lack, and it turns RuView from a model into sensing infrastructure. (Ties to ADR-135 coherence gate.)
+
+## 3. Experiment plan — three variants, frozen-decoder test
+
+Same split, same decoder, same seed set; only the embedding changes.
+
+| Variant | Description | Success threshold (cross-subject torso-PCK) |
+|---------|-------------|----------------------------------------------|
+| **E1** | Masked CSI pretrain | **+3** |
+| **E2** | Pose-contrastive across subjects | **+6** |
+| **E3** | Physics-normalized SSL + skeleton head | **+10** |
+
+### 3.1 Expected gains (estimate)

+| Method | cross-subject torso-PCK gain |
+|--------|------------------------------|
+| Naïve embedding | 0–2 |
+| DANN adversarial | 0–3 (high collapse risk) — *empirically ~0* |
+| Masked CSI pretrain | +3–8 |
+| Pose-contrastive | +5–12 |
+| Physics-norm + SSL + graph decoder | +10–20 |
+| + more subject-diverse paired data | +20 |
+
+Plausible trajectory: 11.6% → **20–25% near term**, **30–40% with enough subject/environment diversity**. That is a stronger research claim than squeezing random-split from 81.6% → 88%.
+
+### 3.2 Empirical findings (2026-05-31) — measured, not estimated
+
+The near-term algorithmic estimates in §3.1 were **tested directly on the official MM-Fi
+cross-subject split** (256,608 train / 64,152 test, same TF pipeline). Measured results:
+
+| Method | §3.1 estimate | **Measured** | Verdict |
+|--------|--------------:|-------------:|---------|
+| Baseline (in-harness) | — | 63.13% (doc TTA 64.04) | reference |
+| Mixup | n/a | **+0.7** → 63.79% | ✅ small |
+| Mixup + TTA + 3-seed ensemble | n/a | **+0.9** → **64.92%** | ✅ **best** |
+| Per-antenna instance-norm + SpecAugment | n/a | **−4.6** → 58.52% | ❌ destroys cross-antenna pose structure |
+| **Pose-contrastive foundation pretrain** | **+5 to +12** | **−2.3** → 62.65% | ❌ **refuted** |
+| DANN adversarial | ~0 | ~0 | ❌ (as predicted) |
+
+**Why pose-contrastive pretraining fails — the key finding.** The supervised-contrastive
+pretraining loss (positives = same pose-cluster, spanning subjects) **never left the
+uniform-similarity floor `ln(B)`** — across cluster granularities K∈{48,256}, batch sizes
+{768,1024}, and 3 seeds. The same encoder trivially aligns *temporally-adjacent* frames
+(temporal-triplet SSL reached 82%), so the optimizer works; it simply **cannot pull same-pose
+CSI from different subjects together — that invariance is not present in the data to be learned.**
+
+**Implication for this ADR.** The 18-pt in-domain↔cross-subject gap (83.6% → best 64.9%) is
+**fundamental subject-distribution shift in CSI, not an algorithmic gap.** No invariance-learning
+method tested moves it; only variance-reduction (mixup + ensemble) gives <1 pt. This **promotes
+"more subject-diverse paired data" (§3.1 last row, §6 alt 3) from complementary to the *primary*
+lever** and **demotes pure-SSL-on-existing-data** as a near-term cross-subject win. The encoder is
+still worth building for masked-CSI representation reuse and the coherence integrity head, but the
+cross-subject acceptance gate (§4, ≥6 pts) is **unlikely to be met without new multi-subject
+capture** (fleet: `cognitum-seed-1` + multi-room, see `CLAUDE.local.md`). Recommend re-scoping
+phase 1 around data collection before further loss-stack engineering.
+
+### 3.3 Subject-scaling study (2026-05-31) — capture *diversity*, not *volume*
+
+Before committing to capture, we measured **how cross-subject accuracy scales with the number of
+training subjects** (fixed held-out test subjects, official split, mixup+TTA):
+
+| N subjects | 4 | 8 | 12 | 16 | 20 | 24 | 32 |
+|-----------:|--:|--:|---:|---:|---:|---:|---:|
+| xsubj-PCK@20 | 36.7 | 57.7 | 58.3 | 61.1 | 62.7 | 63.3 | **63.7** |
+
+The curve **saturates**: 4→8 subjects = **+21 pts**, but 24→32 = **+0.45 pts**. Asymptote ≈ 64–65%,
+still ~19 pts under in-domain. **Key correction to the "more data" recommendation:** simply capturing
+*more people from the same distribution* will **not** close the gap — subject-count returns vanish
+past ~16–20 subjects. The residual is **device/room/protocol shift** (MM-Fi's cross-subject split is
+partly cross-environment by construction). **Re-scoped phase-1 capture target: maximize DIVERSITY
+(rooms, devices, antenna geometries, traffic protocols), not headcount** — and pair it with few-shot
+target-domain adaptation (a handful of labeled frames from the deployment room), which the saturation
+curve implies will beat any amount of additional source subjects. This makes the encoder's
+*domain-invariance* objective (vs the failed subject-invariance one) the design priority.
+
+### 3.4 Few-shot target adaptation (2026-05-31) — the actionable resolution
+
+The saturation curve predicts a few labeled frames from the *deployment* room beat more source
+subjects. Confirmed. Base trained on all 32 source subjects (63.7% zero-shot on a disjoint 50%
+held-out of the target subjects), then fine-tuned on K labeled frames per target subject:
+
+| K/subject | total frames | eval PCK@20 | Δ |
+|----------:|-------------:|------------:|--:|
+| 0 | 0 | 63.7% | — |
+| 20 | 160 | 68.1% | +4.3 |
+| **50** | **400** | **72.2%** | **+8.5 (≈ prior SOTA)** |
+| 200 | 1,600 | 76.1% | +12.4 |
+| 1000 | 8,000 | 78.3% | +14.6 |
+
+**Few-shot calibration dominates source volume.** §3.3 showed +24 source subjects (~190K frames)
+buys +6 pts; here **200 target frames/subject (1,600 frames) buys +12.4 pts**. This **re-scopes the
+ADR's acceptance gate and deployment story**: the cross-subject gate (§4, ≥6 pts) is *trivially* met
+by ~50–200 labeled frames of in-room calibration — no foundation encoder or mass capture required for
+the deployment win. **Recommended product behavior:** ship a **~30-second on-site calibration** (a few
+hundred labeled frames per room/person) that recovers most of the gap. The foundation encoder's value
+shifts from "close cross-subject zero-shot" (data says: hard) to "make the few-shot adaptation faster /
+need fewer calibration frames" — a better-posed, achievable objective. **This supersedes the §3.2
+pessimism: the frontier is not closed by algorithms or bulk data, but it *is* cheaply closed at
+deployment time by few-shot calibration.**
+
+> **Task-general (2026-05-31).** The same mechanism was verified on a *second* MM-Fi task —
+> 27-class **action recognition** (which the MM-Fi paper never benchmarked for WiFi). Zero-shot
+> cross-subject collapses to ~10% (near-chance), and few-shot calibration recovers it: 50 samples →
+> 36%, 200 → 59%, 1000 → 76%. Action needs more calibration than pose (classification vs regression),
+> but the pattern is identical. **Few-shot in-room calibration is the universal deployment answer for
+> WiFi sensing generalization, not a pose-specific result.** (Optimization report §36.)
+
+### 3.5 Deployable adapter calibration (2026-05-31) — the calibration-service mechanism
+
+Full-finetune calibration (§3.4) means a 2.3 MB model copy per room. Compared calibration methods at
+K=200 frames/subject by accuracy *and* adapter size:
+
+| Method | PCK@20 | trainable | adapter |
+|--------|-------:|----------:|--------:|
+| zero-shot | 63.6% | — | — |
+| **LoRA rank-8** | **72.5%** | 11,200 | **~11 KB** |
+| head+graph only | 72.7% | 121,828 | 119 KB |
+| frozen-trunk | 73.5% | 212,453 | 207 KB |
+| full finetune | 76.2% | 2.32 M | 2.3 MB |
+
+**A ~11 KB LoRA adapter recovers +8.9 pts (→72.5%, ≈ prior SOTA) at 0.5 % the model size.** This is
+the concrete mechanism for the **RuView calibration service** the project wanted: ship the shared
+base once; each room contributes a 30-second labeled calibration → a **~11 KB per-room LoRA adapter**
+→ SOTA-level cross-subject pose, thousands of rooms on one base. Accuracy/size knob:
+LoRA 11 KB @ 72.5 % → frozen-trunk 207 KB @ 73.5 % → full 2.3 MB @ 76.2 %. **Net for this ADR:** the
+encoder/adapter split is validated empirically — a frozen shared trunk + tiny per-room LoRA is the
+deployable path, and the foundation-encoder objective should be "make this adapter even smaller /
+need fewer calibration frames."
+
+**Calibration data requirement (measured, 3 seeds):** the 11 KB LoRA needs **~100–200 labeled
+samples/room** to reach ~72% (knee at ~50 → 70%); below ~20 samples it can't fit and may *hurt*
+(5 samples → 61% < zero-shot 64%). So the evidence-complete **calibration-service spec** is:
+ship shared base → collect **~100–200 labeled samples on-site** → fit a **~11 KB LoRA** →
+**~72% cross-subject** (SOTA-level). The encoder's research goal is now precisely posed: push that
+~100–200-sample requirement down and/or lift the >72% ceiling per fixed calibration budget.
+
+### 3.6 Cross-ENVIRONMENT few-shot (2026-05-31) — no unsolved deployment case
+
+The hard frontier — unseen room *and* unseen people (cross-environment) — was thought ~unsolvable
+(zero-shot ~10–17%). Few-shot calibration rescues it **even more dramatically than cross-subject**:
+
+| K labeled samples/subject | cross-env PCK@20 | Δ zero-shot |
+|--------------------------:|-----------------:|------------:|
+| 0 | 10.6% | — |
+| **5** | **60.1%** | **+49.5** |
+| 20 | 66.0% | +55.5 |
+| 50 | 70.0% | +59.4 |
+| 200 | 73.1% | +62.5 |
+| 1000 | 75.4% | +64.8 |
+
+**Just 5 calibration samples per person lift an unseen room from ~unusable (10.6%) to 60%.** An
+unseen room is one *coherent* domain shift a handful of labeled frames pin down instantly — so the
+biggest zero-shot gap yields the biggest few-shot gain. **Campaign conclusion:** the "unsolved
+cross-environment frontier" was a *zero-shot framing artifact*. With the ~11 KB LoRA calibration
+mechanism (§3.5), **there is no unsolved deployment case** — any new room/person reaches SOTA-level
+pose from ~5–200 labeled samples. This **reframes the entire generalization objective**: stop chasing
+zero-shot invariance (hard, low-value); ship fast few-shot calibration (easy, high-value). The
+foundation encoder's worth is now solely "reduce calibration samples / raise the per-budget ceiling,"
+not "close zero-shot." Recommend **accepting** this ADR re-scoped around the calibration mechanism.
+
+## 4. Acceptance Test
+
+The encoder is accepted **only if it improves cross-subject torso-PCK@20 by ≥ 6 absolute points without reducing random-split torso-PCK@20 by more than 2 points** — on the same MM-Fi pipeline, one-command reproduction, with per-joint error tables. Results land as AetherArena witness rows (ADR-149), nothing published until reviewed.
+
+## 5. Consequences
+
+**Positive:** a reusable, self-supervised RF foundation encoder for CSI/CIR/BFLD; the first principled attack on the cross-subject frontier; the coherence head adds an anti-hallucination integrity signal no competitor has.
+
+**Negative / risk:** SSL pretraining requires matching the production CSI→feature pipeline (ADR-149 §SSL note flagged the resampling-replication risk); the multi-loss stack needs careful weight tuning (DANN showed loss-imbalance can collapse training); physics normalization must be validated not to discard pose-relevant deltas.
+
+**Neutral:** the in-domain head is unchanged; the encoder slots in front of the existing pose decoder.
+
+## 6. Alternatives Considered
+
+1. **Bigger model only** — tested; *hurts* cross-subject (overfits seen subjects).
+2. **Naïve DANN subject-adversarial** — tested; no gain, collapse risk; entangles pose evidence.
+3. **More data only (camera/ADR-079)** — complementary and ultimately necessary, but slow and out-of-band; the encoder extracts more from existing data first.
+
+## 7. Open Questions
+
+1. Physics-normalization spec — exact antenna/subcarrier/phase terms, validated to preserve pose deltas.
+2. Masked-CSI SSL on the production feature pipeline (resampling match — see ADR-149).
+3. Where the coherence/mincut integrity signal is computed (reuse ADR-135 coherence gate vs new head).
+4. CIR (ADR-134) / BFLD fusion into the same encoder — phase 3.

+
+## 1. Context
+
+### 1.1 The thesis — teach the room before you teach the model
+
+RuView's deployment frontier is not a better generic model. ADR-150 documents the wall directly: an MM-Fi pose head scores **81.63% torso-PCK@20 in-domain but ~11.6% leakage-free cross-subject**, and bigger capacity *hurts* cross-subject (transformer 24.8% < conv 27.3%). A single oversized model that "understands the world" overfits the rooms and bodies it has seen. The lever is the opposite of scale: **a small model that understands *one* room and *one* person**, calibrated in minutes, run locally, and specialised per biological signal.
+
+This positions RuView between the two incumbents in ambient sensing:
+
+- **Wearables** — high fidelity, but people forget to wear them, and they only measure the wearer.
+- **Cameras** — powerful, but invasive, store identifiable video, and fail in the dark / under covers.
+
+RuView sits in the middle: it learns the *space*, learns the *person*, and tracks biological rhythm (breathing, heartbeat, restlessness, posture, presence) without seeing skin or storing video. Heartbeat and breathing are not visual problems — they are tiny, repeating disturbances in the RF field. Capturing them well is a *calibration* problem, not a *model-size* problem.
+
+### 1.2 What already exists (and what is missing)
+
+The pieces of a calibration→training pipeline exist as disconnected modules. There is no system that runs them end to end and emits a per-room model bank.
+
+| Capability | Status today | Gap |
+|------------|--------------|-----|
+| Empty-room baseline (environmental fingerprint) | ADR-135 `BaselineCalibration` (Proposed): per-subcarrier amplitude + circular-phase stats, `ruvcal` NVS namespace | Captures the *room*, but there is no step that captures *guided human anchors* on top of it |
+| Field eigenstructure | ADR-030 `field_model.rs` (SVD room eigenmodes) | Consumes calibration; not wired to a training trigger |
+| Shared invariant backbone | ADR-150 RF Foundation Encoder (pose-preserving, subject/room/device-invariant) | Defined as a *foundation* embedding; nothing distills it into per-room specialists |
+| Few-shot adaptation | `train/src/rapid_adapt.rs` — test-time training → LoRA weight deltas (MERIDIAN P5) | Produces a *single* pose-adaptation delta, not a bank of per-modality specialists |
+| Feature extractors | `ruvsense/{bvp,longitudinal,intention,gesture,pose_tracker,adversarial}.rs`, `train/src/signal_features.rs` | Each emits a signal; none is packaged as a labelled training source for enrollment |
+| Small-model storage | `wifi-densepose-ruvector` (RVF cognitive containers, HNSW, sketch) | No schema for "a bank of specialist models scoped to a room_id" |
+| HF publishing | ADR-149 AetherArena (Hugging Face Space + signed scorer), `sensing-server` `from_pretrained` path | Publishes/評価s a *global* model; no notion of a published *base* + private *local* heads |
+
+**The missing system is the connective tissue**: a guided enrollment protocol, a feature-extraction-to-label bridge, a specialist-bank trainer that reuses the frozen HF backbone, and a runtime that fuses the specialists with confidence gating. This ADR defines that system.
+
+### 1.3 The four-step user model (and where each step lands)
+
+The system is deliberately presented to operators as four plain steps. Each maps to existing or new code:
+
+1. **Capture a quiet baseline** — no people, just room/router/reflections/noise/drift → the *environmental fingerprint*. → **Reuse ADR-135** `BaselineCalibration` + **ADR-030** field eigenmodes. No new capture code; the calibration crate calls it.
+2. **Capture guided samples** — stand, sit, lie down, slow vs normal breathing, small movement, sleep posture. Clean anchors, not hours of data. → **NEW** `EnrollmentProtocol` (Section 2.2).
+3. **Extract the useful signal** — CSI phase, amplitude, Doppler shift, micro-motion, periodicity, variance, timing. → **Reuse** `signal_features.rs` + ruvsense extractors, packaged as labelled `AnchorFeature` records (Section 2.3).
+4. **Compress patterns into small ruVector models** — *specialised* per signal: breathing, heartbeat, sleep restlessness, posture, presence, anomaly. → **NEW** `SpecialistBank` trained via `rapid_adapt` LoRA heads over the frozen ADR-150 backbone, stored as RVF (Section 2.4).
+
+---
+
+## 2. Decision
+
+**Build the RuView Per-Room Calibration & Specialized Model Training System: a four-stage, local-first pipeline (`baseline → enroll → extract → train`) that produces a versioned *bank of small specialised ruVector models* scoped to one `room_id`, each a lightweight head distilled/adapted from the frozen, Hugging-Face-published RF Foundation Encoder (ADR-150).** Big model understands the world; small ruVector models understand *your room*.
+
+Two invariants govern every design choice below:
+
+> **(A) Specialisation over scale.** One small model per biological signal, not one large model for all of them. Each specialist is faster, cheaper, more private, and — because it is calibrated to the room's actual fingerprint — often *more accurate* than a general model.
+>
+> **(B) Local-first, base-shared.** The frozen room/subject/device-invariant backbone is the only artifact published to Hugging Face. Per-room baselines and per-specialist heads never leave the device unless the operator opts into federation (ADR-105).

+```
+
+The shared backbone is loaded **once per device** and frozen. Every specialist is a small head over its embedding — so the marginal cost of a sixth specialist is kilobytes of LoRA weights, not another full model.
+
+### 2.2 Stage 2 — the guided enrollment protocol (NEW)
+
+`EnrollmentProtocol` is a CLI-driven state machine that walks the operator through a fixed sequence of labelled **anchors**. The design rule from the user vision is explicit: *clean anchors, not hours of data.* Each anchor is a short (default 20 s @ 20 Hz = 400 frames) labelled clip captured against the already-recorded baseline.
+
+| Anchor | Label | Duration | Primary signal taught | Feature emphasis |
+|--------|-------|----------|-----------------------|------------------|
+| `empty` | presence=0 | (reuse ADR-135 baseline) | absence reference | amplitude variance floor |
+| `stand_still` | posture=standing, presence=1 | 20 s | static human load | amplitude mean shift, eigenmode delta |
+| `sit` | posture=sitting | 20 s | lower static load | amplitude profile |
+| `lie_down` | posture=lying | 20 s | sleep-position load | amplitude profile, low Doppler |
+| `breathe_slow` | resp≈0.1–0.15 Hz | 30 s | slow respiration | periodicity, micro-Doppler |
+| `breathe_normal` | resp≈0.2–0.3 Hz | 30 s | normal respiration | periodicity, BVP phase |
+| `small_move` | motion=1 | 20 s | limb micro-motion | Doppler spread, variance |
+| `sleep_posture` | posture=lying, restless=0 | 30 s | quiescent sleep baseline | long-window variance, timing |
+
+The protocol is **adaptive**: an anchor is only accepted when its captured features pass a quality gate (coherence ≥ threshold from `coherence_gate.rs`, sufficient SNR vs baseline, no saturation). A failed anchor is re-prompted rather than silently kept — bad anchors poison small models far more than large ones. Total guided enrollment is ~4 minutes of wall-clock, producing 8 clean anchors. This is intentionally far below the "hours of data" that a from-scratch model needs, because the backbone already carries world knowledge; enrollment only teaches *this* room's offsets.
+
+Anchors are persisted as an append-only `EnrollmentSession` (event-sourced, per CLAUDE.md state rules) under `room_id`, so re-enrollment is incremental and auditable.
+
+### 2.3 Stage 3 — feature extraction to labelled records (REUSE + bridge)
+
+Each accepted anchor clip is run through the existing extractor stack, baseline-subtracted per ADR-135, and packaged into an `AnchorFeature` record. No new DSP is invented — this stage is a *bridge*, not a new algorithm.
+
+| Feature group | Source module | Used by specialists |
+|---------------|---------------|---------------------|
+| CSI amplitude mean/variance | ADR-135 baseline subtraction + `signal_features.rs` | presence, posture |
+| CSI phase (sanitised, LO-aligned) | `phase_sanitizer` → `phase_align` | posture, heartbeat |
+| Doppler shift / micro-Doppler | `ruvsense/bvp.rs`, `breathing` path | breathing, small-move |
+| Micro-motion / intention lead | `ruvsense/intention.rs` | restlessness, anomaly |
+| Periodicity / spectral peaks | `bvp.rs` autocorrelation + FFT | breathing, heartbeat |
+| Long-window variance / drift | `ruvsense/longitudinal.rs` (Welford) | restlessness, presence |
+| Timing / inter-frame epoch | `c6_timesync` epoch, frame Δt | all (rhythm alignment) |
+| Field eigenmode coefficients | ADR-030 `field_model.rs` | posture, presence |
+
+`AnchorFeature` = `{ room_id, anchor_label, t_epoch_us, embedding: [f32; D] (backbone output), aux: { resp_hz?, doppler_spread, variance, periodicity_score, eigen_coeffs } }`. The backbone embedding is the *shared* representation; `aux` carries the cheap hand-features that let small heads specialise without re-learning DSP.
+
+### 2.4 Stage 4 — the specialist bank (NEW, the core contribution)
+
+A **`SpecialistBank`** is a versioned collection of small models scoped to one `room_id`, persisted as a single RVF cognitive container (`wifi-densepose-ruvector`). Each specialist is a *head* over the frozen backbone embedding, trained from the labelled `AnchorFeature` records via the existing `rapid_adapt.rs` LoRA machinery (test-time/few-shot training, contrastive + entropy losses), **not** a from-scratch network.
+
+| Specialist | Model type | Params (typ.) | Label source | Output |
+|------------|-----------|---------------|--------------|--------|
+| **breathing** | 1-D temporal head + periodicity regressor | ~8 KB LoRA + aux | `breathe_slow`/`breathe_normal` | resp rate (Hz) + confidence |
+| **heartbeat** | narrowband phase head (harmonic-aware) | ~12 KB | quiescent anchors + periodicity | HR (bpm) + confidence |
+| **sleep restlessness** | variance/drift classifier | ~4 KB | `sleep_posture` vs `small_move` | restlessness score [0,1] |
+| **posture** | k-way prototype classifier (HNSW NN) | prototypes only | `stand/sit/lie` anchors | posture class + margin |
+| **presence** | binary energy/eigenmode gate | ~2 KB | `empty` vs occupied anchors | presence prob |
+| **anomaly** | one-class / physically-impossible detector (`adversarial.rs`) | ~6 KB | baseline + all anchors (novelty) | anomaly score + veto flag |
+
+Design properties that follow from invariant (A):
+
+- **Independently versioned & swappable.** Re-enrolling breathing does not retrain posture. A specialist carries its own `{trained_at, anchor_set_hash, baseline_hash, backbone_rev}`.
+- **HNSW prototype storage for the classifiers.** Posture and presence are nearest-prototype lookups in the RVF index — no inference engine, microsecond latency, and new postures are added by inserting a prototype, not retraining.
+- **SONA online adaptation.** Each specialist may carry a SONA/MicroLoRA online-adaptation slot (`ruvllm_sona_*` / `microlora` primitives) so it tracks slow drift (furniture moved, seasonal RF change) between full re-enrollments, gated by ADR-135 baseline drift.
+- **Teacher–student distillation (optional, offline).** Where a labelled public corpus exists (MM-Fi, Wi-Pose), the ADR-150 backbone acts as teacher to pre-shape a head before per-room fine-tuning, improving cold-start. The *teacher* is global/HF; the *student head* is local.
+
+**Invalidation contract.** The bank stores the `baseline_id` (the baseline UUID) it was trained against. **As implemented**, the runtime marks the bank `STALE` whenever the *current* baseline id differs from the trained one — a conservative trigger that catches re-calibration (room rearranged, AP moved, band changed) because any of those produces a new baseline. A finer **drift-threshold** trigger (mark STALE when ADR-135's per-subcarrier deviation exceeds τ *without* a full re-baseline) is a planned refinement (P6). Either way the runtime prompts re-enrollment rather than emitting silently wrong vitals — the calibration analogue of the #954 `DEGRADED` honesty rule: never report confident numbers from an invalid model.
+
+### 2.5 Runtime — mixture of specialists with confidence gating
+
+At inference, the frozen backbone embeds each CSI window once; every specialist consumes that shared embedding and emits `{value, confidence}`. Fusion rules:
+
+- The **anomaly** specialist holds a **veto**: a high anomaly score (physically-impossible signal per `adversarial.rs`, or a coherence-gate `Reject`) suppresses positive vitals/posture output and raises a flag, rather than propagating a hallucinated reading.
+- **presence=0** short-circuits breathing/heartbeat/posture to `null` (you cannot have a respiration rate in an empty room).
+- Each emitted reading is tagged with the specialist's confidence and the `baseline_hash`/`backbone_rev` provenance, so downstream consumers (sensing-server, MQTT, Home Assistant) can gate on quality — consistent with ADR-135 coherence-gate semantics.
+
+### 2.6 Crate & module layout
+
+New bounded-context crate `wifi-densepose-calibration` (orchestration only; files < 500 lines, typed public APIs, event-sourced sessions — per CLAUDE.md):
+
+```
+wifi-densepose-calibration/
+  src/
+    lib.rs                 # public API: CalibrationSystem facade
+    enrollment.rs          # EnrollmentProtocol state machine (Stage 2)
+    anchor.rs              # Anchor, EnrollmentSession (event-sourced)
+    extract.rs             # AnchorFeature bridge over signal_features + ruvsense (Stage 3)
+    specialist.rs          # Specialist trait, SpecialistKind enum
+    bank.rs                # SpecialistBank (RVF container, versioning, invalidation)
+    runtime.rs             # MixtureOfSpecialists fusion + veto (Stage 5)
+    backbone.rs            # frozen ADR-150 encoder loader (hf_hub from_pretrained, cached)
+    error.rs
+```
+
+Dependencies (no duplication — orchestrates existing crates): `wifi-densepose-signal` (ruvsense extractors, ADR-135 baseline), `wifi-densepose-train` (`rapid_adapt`, `signal_features`, `trainer`), `wifi-densepose-ruvector` (RVF, HNSW), `wifi-densepose-nn` (backbone inference). The `wifi-densepose-cli` gains `enroll`, `train-room`, and `room-status` subcommands, sequenced after the existing ADR-135 `calibrate`.
+
+### 2.7 CLI flow (operator-facing)
+
+```bash
+# Stage 1 — environmental fingerprint (ADR-135, existing)

+```
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- **Fidelity through specialisation.** Six small calibrated heads beat one oversized general model on the cross-room/cross-subject frontier that ADR-150 quantified — and each runs in microseconds-to-milliseconds, on-device.
+- **Privacy by construction.** Only the room-agnostic backbone is public (HF). The environmental fingerprint and the person-specific heads stay local; no video, no skin, no cloud round-trip. This is the core differentiator vs cameras and the convenience differentiator vs wearables.
+- **Minutes, not hours.** Because the backbone carries world knowledge, ~4 minutes of clean anchors calibrates a room. Re-enrollment is incremental.
+- **Honest degradation.** The `baseline_hash` invalidation + anomaly veto mean an out-of-calibration room reports `STALE`/flagged rather than confidently wrong — the same honesty principle as the firmware `DEGRADED` flag.
+- **Composable & cheap to extend.** A new biological signal = a new small head over the same embedding, not a new model.
+
+### 3.2 Negative / risks
+
+- **Backbone dependency.** Every specialist rides on ADR-150's encoder; its quality and revision compatibility (`backbone_rev`) are a single point of leverage. Mitigation: pin `backbone_rev` in each specialist; distillation cold-start reduces sensitivity.
+- **Enrollment burden.** 4 minutes is small but non-zero, and anchor quality depends on the operator following prompts. Mitigation: adaptive re-prompting + quality gates; ship sane defaults so a partial bank (presence+posture) works after just the static anchors.
+- **Heartbeat is hard.** Sub-mm chest displacement at HR frequencies is near the ESP32-S3 noise floor; the heartbeat specialist will have lower and more variable confidence than breathing. The confidence-gated runtime surfaces this rather than faking it.
+- **Per-room storage proliferation.** A bank per room per person; needs a clear RVF lifecycle (list/prune/export) — handled by `bank.rs` versioning and the `room-status` CLI.
+
+### 3.3 Alternatives considered
+
+| Alternative | Verdict | Reason |
+|-------------|---------|--------|
+| One large general model for all signals | **Rejected** | The ADR-150 evidence: scale overfits rooms/subjects and collapses cross-domain; also slower, costlier, less private. Directly contradicts invariant (A). |
+| Cloud training of per-room models | **Rejected** | Violates invariant (B): would ship raw CSI of a person's home/sleep to a server. Local-first is the privacy promise. Federation (ADR-105) is the *opt-in* path for shared improvement, exchanging gradients/deltas, never raw CSI. |
+| Skip the backbone; train each specialist from scratch | **Rejected** | Reintroduces the "hours of data" requirement the user vision explicitly rejects, and loses cross-room priors. |
+| Fold this into ADR-135 | **Rejected** | ADR-135 is *room* calibration (no humans). This ADR is *human-anchor* enrollment + model training on top of it. Distinct lifecycles, distinct invalidation; kept as separate bounded contexts. |

+## 4. Implementation phases
+
+| Phase | Scope | Exit criterion | Status |
+|-------|-------|----------------|--------|
+| **P1** | Scaffold `wifi-densepose-calibration` crate; `AnchorFeature` schema; (backbone via `hf_hub` deferred) | Crate + schema; unit tests | ✅ Done (crate + Stage-1 baseline via `calibrate`/`calibrate-serve`; HF backbone deferred) |
+| **P2** | `EnrollmentProtocol` + `anchor.rs` (event-sourced sessions) + CLI `enroll` with quality gates | 8-anchor enrollment; bad anchors re-prompt | ✅ Done (`anchor.rs`, `enrollment.rs`, CLI `enroll`) |
+| **P3** | `extract.rs` bridge → labelled records; baseline subtraction (ADR-135) | `AnchorFeature` records persisted per `room_id` | ✅ Done (`extract.rs`; autocorr periodicity + variance/motion) |
+| **P4** | `SpecialistBank` + presence/posture (prototype) + breathing (periodicity); persistence + versioning | `train-room` produces a bank; `room-status` reads it back | ✅ Done (`specialist.rs`, `bank.rs`, CLI `train-room`/`room-status`; JSON persistence — RVF/HNSW = future) |
+| **P5** | heartbeat + restlessness + anomaly specialists; `runtime.rs` mixture + veto + confidence gating | End-to-end RoomState on hardware; anomaly veto verified | ✅ Done (`runtime.rs`, CLI `room-watch`; breathing read live on COM8 ESP32) |
+| **P6** | Baseline-drift `STALE` invalidation; SONA online adaptation; optional ADR-105 federation; HF teacher–student distillation | Drift marks bank STALE; AetherArena entry | ◐ Partial (STALE done; SONA/federation/HF-backbone = follow-ups) |
+
+**Current status (2026-06-10):** Stages 1–5 implemented with *statistical* specialists (threshold/prototype/autocorrelation). 55 tests (35 unit incl. multistatic + 1 full-loop integration + 19 CLI), all passing under qemu-aarch64. **Validation scope is precise:** baseline capture + HTTP API + auth are proven on real CSI (Pi-5 nexmon, 6,813 frames; and an ESP32-S3). The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`tests/full_loop.rs`: clean baseline with zero motion flags, 8/8 anchors through the quality gate, 6 specialists trained, JSON bank round-trip, trained-bank inference 18±2 BPM positive / absent negative / foreign-baseline STALE; seed-robust). The one live runtime signal (breathing ~16–31 BPM via `room-watch`) used the *stateless* breathing head, **not** a trained bank; the clean empty-room loop has **not** yet run on-target — the remaining gap is strictly the hardware session (empty room + operator anchors). The four behavioral findings from the full-loop test (z-band squeeze, variance-only presence, ungated hz embedding, heart-band lag-floor leakage) are FIXED and regression-guarded — see the integration doc §7. SOTA-intake decisions affecting this system (geometry conditioning, checkerboard alignment) are recorded in ADR-152. Open refinements: `--source-format adr018v6` (drive from the Pi's own nexmon), phase-based breathing carrier, RVF/HNSW storage, and the ADR-150 frozen HF backbone the specialists would distill from.
+
+Validation per CLAUDE.md: `cargo test --workspace --no-default-features` green; hardware verification on the ESP32-S3 (currently COM8) before any release; witness bundle regenerated if the proof surface changes.
+
+---
+
+## 5. Summary
+
+> Big models understand the world. Small ruVector models understand *your room*.
+
+ADR-151 makes that operational: a local-first `baseline → enroll → extract → train` pipeline that turns ~4 minutes of clean human anchors — layered on ADR-135's empty-room fingerprint and ADR-150's Hugging-Face-published invariant backbone — into a versioned bank of tiny, specialised, privacy-preserving models for breathing, heartbeat, restlessness, posture, presence, and anomaly. Specialisation over scale; local heads over a shared base; honest `STALE` degradation over confident error.

+
+## 1. Context
+
+A structured survey of the 2025–2026 WiFi human-sensing state of the art was run on 2026-06-10 to answer: *what should RuView integrate next, and does anything published invalidate our current direction?* Every claim below was verified against the primary source by independent adversarial reviewers; **evidence grades distinguish what the papers measured from what they merely claim**. Almost all performance numbers are author-self-reported preprint results — treated here as CLAIMED until reproduced on our hardware.
+
+### 1.1 The five verified findings
+
+**(F1) "Coordinate overfitting" is a named, diagnosed failure mode of camera-supervised WiFi pose — and our ADR-079 pipeline has the exact shape of it.**
+PerceptAlign (arXiv [2601.12252](https://arxiv.org/abs/2601.12252), accepted ACM MobiCom 2026) shows that models regressing CSI directly to camera-frame coordinates memorize the deployment-specific transceiver layout; SOTA baselines degrade to >600 mm MPJPE in unseen scenes. Their fix is cheap: a <5-minute calibration using two checkerboards and a few photos to align WiFi and vision in one shared 3D frame, plus **fusing transceiver-position embeddings with CSI features**. Claimed: −12.3% in-domain error, −60%+ cross-domain error. They release the claimed-largest cross-domain 3D WiFi pose dataset (21 subjects, 5 scenes, 18 actions, **7 device layouts**). *Evidence: improvements CLAIMED (preprint w/ MobiCom acceptance); the failure mode itself is corroborated across the cross-domain literature — and independently by our own ADR-150 data (81.63% in-domain vs ~11.6% leakage-free cross-subject torso-PCK).*
+
+**(F2) An external model named "WiFlow" claims 97.25% PCK@20 with 2.23M params and ships everything.**
+arXiv [2602.08661](https://arxiv.org/abs/2602.08661) (Apr 2026) — spatio-temporal-decoupled CSI pose, 97.25% PCK@20 / 99.48% PCK@50 / 0.007 m MPJPE, 2.23M parameters (~2.2 MB int8). Code, pretrained weights, and a 360k-sample CSI-pose dataset are public under Apache-2.0 ([repo](https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling), Kaggle dataset). *Evidence: artifact availability MEASURED (verified by direct repo inspection); PCK numbers CLAIMED (5-subject, in-domain, self-collected dataset; hardware unspecified; 15 keypoints vs our 17).* ⚠️ **Name collision:** this is unrelated to RuView's internal WiFlow model. In all RuView docs the external model is referred to as **WiFlow-STD (DY2434)**.
+
+**(F3) For CSI foundation encoders, data scale — not model capacity — is the bottleneck, and the tokenization recipe is now known.**
+UNSW's MAE pretraining study (arXiv [2511.18792](https://arxiv.org/abs/2511.18792), Nov 2025) — the largest heterogeneous CSI pretraining run to date (1,320,892 samples, 14 public datasets incl. MM-Fi, Widar 3.0, Person-in-WiFi 3D; 4 devices; 2.4/5/6 GHz; 20–160 MHz) — reports zero-shot cross-domain gains of 2.2–15.7% over supervised baselines, with unseen-domain performance scaling **log-linearly with pretraining data, unsaturated at 1.3M samples**, while ViT-Base adds only 0.4–0.9% over ViT-Small. Optimal recipe: **80% masking ratio, small (30,3) patches** (+4.7% over (40,5) by preserving fine temporal dynamics). *Evidence: MEASURED within-study (ablations verified in body text) but preprint; downstream tasks are classification, NOT pose — pose transfer is a hypothesis. Independently corroborates ADR-150's finding that capacity hurts cross-subject.*
+
+**(F4) Hardware/standards: 802.11bf is finished; Espressif ships official sensing; Wi-Fi 6 AP CSI is reachable.**
+- **IEEE 802.11bf-2025** published **2025-09-26** (verified against the IEEE SA record) — sensing standardization is complete for both sub-7 GHz and >45 GHz, with formal sensing setup/feedback procedures. No ESP32 silicon implements it yet. *Evidence: MEASURED (standards-body record).*
+- **Espressif `esp_wifi_sensing`** (Apache-2.0, v0.1.x, ESP Component Registry): official CSI presence/motion FSM; esp-csi actively maintained (commit 2026-04-22, verified), CSI confirmed across ESP32/S2/C3/S3/C5/C6/C61. *Evidence: MEASURED (vendor pages + commit log).* ⚠️ A stronger "drop-in compatible with RuView nodes" claim was **REFUTED 0-3** — WiFi-6 parts use a different CSI acquisition config struct.
+- **ZTECSITool** (arXiv [2506.16957](https://arxiv.org/abs/2506.16957), [code](https://github.com/WiFiZTE2025/ZTE_WiFi_Sensing)): CSI from commercial Wi-Fi 6 APs at up to 160 MHz / 512 subcarriers (~5–10× ESP32 subcarrier count; the gain is aperture, not per-Hz granularity). Firmware is gated behind a ZTE serial-number approval. *Evidence: capability CLAIMED by the vendor-authored tool paper; code artifact MEASURED.*
+
+**(F5) Nothing in 2025–2026 does full DensePose UV regression from commodity WiFi.** Keypoint pose remains the field's frontier. Three "wireless foundation model" papers were screened out by full-text inspection (HeterCSI = simulated cellular channels only; the NeurIPS-2025 FMCW pilot = mmWave radar, presence-only; arXiv 2509.15258 = survey, no artifacts). *Evidence: MEASURED (absence verified by full-text inspection of the candidates that surfaced; absence of evidence across the whole literature is necessarily weaker).*
+
+### 1.2 What this means for the ADR-151 calibration system
+
+ADR-151's enrollment protocol captures guided human anchors but does **not** record or condition on transceiver geometry. F1 says that omission is precisely the thing that makes camera-supervised (and, plausibly, anchor-supervised) heads layout-brittle. ADR-151's per-room thesis ("teach the room before you teach the model") is *strengthened* by F1 — PerceptAlign is independent evidence that layout must be modeled explicitly — and the fix composes naturally with our Stage-2 enrollment.
+
+ADR-150's masked-CSI-encoder design is *validated* by F3, which also hands us the hyperparameters and the priority call: **collect/aggregate more heterogeneous CSI before scaling the encoder.**
+
+## 2. Decision
+
+Adopt four changes, ordered by effort-vs-gain:
+
+### 2.1 Geometry-condition the calibration system (extends ADR-151 Stage 2) — ACCEPTED
+
+1. **Record transceiver geometry at enrollment.** `EnrollmentProtocol` gains an optional `NodeGeometry` record per node (position estimate, antenna orientation, inter-node distances where known). Stored alongside the room baseline in the bank; schema-versioned so existing banks remain readable.
+2. **Fuse geometry embeddings into specialist training.** Where a specialist head consumes the (future, ADR-150) backbone embedding, concatenate a small learned embedding of `NodeGeometry` — the PerceptAlign mechanism, transplanted to our per-room banks. Statistical specialists (current) ignore it; LoRA heads (ADR-151 P6) consume it.
+3. **Adopt the two-checkerboard alignment for the camera-supervised path (ADR-079).** When MediaPipe supervision is used, calibrate camera↔WiFi into one shared 3D frame before regression (<5 min, two checkerboards, a few photos). This is the direct defense against F1 for our camera-supervised pipeline. ~~92.9%-PCK@20~~ — *that figure was retracted during measurement (b) (2026-06-10): the surviving holdout shows a constant-output model under an absolute (non-torso) threshold on 69 near-static frames; mean predictor scores 100% under the same protocol. The §2.2 no-citation rule now applies to it.*
+4. **Evaluate on the PerceptAlign cross-domain dataset** (21 subjects / 7 layouts) as the MERIDIAN cross-layout benchmark — *gated on confirming its license and downloadability* (open question; repo per paper: github.com/Trymore-lab/PerceptAlign).
+   > **Gate resolved (2026-06-10, MEASURED by repo inspection):** repo exists, **MIT license**, dataset downloadable from HuggingFace (5 per-scene repos, raw CSI + separate vision keypoints; Intel 5300, 1TX×3RX×3 ant, 57 subcarriers — same order as ESP32 subcarrier counts; Scene3 ships 3 distinct layouts). Code present, no pretrained weights. Benchmark adoption unblocked; dataset-side license terms inherit HF dataset terms (not separately stated — check at download time).
+
+### 2.2 Benchmark against WiFlow-STD (DY2434) — ACCEPTED
+
+Pull the Apache-2.0 weights + 360k-sample dataset; run three measurements: (a) their model on their data (reproduce 97.25% claim), (b) their model fine-tuned on our ESP32 17-keypoint eval set, (c) our internal WiFlow on their dataset (15-keypoint subset mapping). Until (a)–(c) are measured, **no RuView doc may cite 97.25% as a comparable number** — different dataset, subjects, keypoints.
+
+> **Status (2026-06-10, measurement (a) complete — `benchmarks/wiflow-std/RESULTS.md`):** shipped checkpoint REFUTED (0.08% PCK@20 — wrong keypoint normalization, predates published code); released code does not run as published (6 defects, incl. broken package import and an unreachable test phase); released dataset's last 13 files are corrupted (9,072 windows: NaN + float32-max garbage, diverges fp16 training via BatchNorm poisoning). After repairing both, retraining with upstream defaults reproduced **96.09% PCK@20 full-test / 96.61% corruption-free / MPJPE 0.0094–0.0098** (published: 97.25% / 0.007) on an RTX 5080. Accuracy claims graded MEASURED-EQUIVALENT; params (2.23M) and FLOPs (~0.055G) verified. (b)/(c) remain open.
+
+### 2.3 Apply the UNSW recipe to the ADR-150 encoder — ACCEPTED (amends ADR-150 §2.3)
+
+- Pretraining corpus: start from the same 14 public datasets (1.3M samples) + our home/MM-Fi frames; data aggregation takes priority over architecture work.
+- Tokenization: 80% masking, (30,3)-class small patches; encoder stays ViT-Small-class (~15M params) — F3 and our own DANN/transformer results agree that capacity does not pay.
+- The published log-linear scaling (unsaturated) sets the expectation: more heterogeneous CSI in, better zero-shot out.
+
+### 2.4 Hardware watch items — ACCEPTED (no code now)
+
+- **802.11bf**: track silicon/certification; OTA binding remains deferred until commodity chipsets expose standardized sensing measurements. **Amended by ADR-153** (2026-06-10): implement a pure Rust forward-compatibility protocol layer now — typed procedure models, a deterministic session FSM, a transport abstraction, simulation tests, and an `OpportunisticCsiBridge` that maps today's ESP32 CSI batches into standardized sensing-report shape.
+- **esp_wifi_sensing**: benchmark our presence pipeline against the vendor FSM (one afternoon; useful external baseline). Do **not** treat as drop-in (refuted claim).
+- **ZTECSITool AP**: optional high-resolution anchor node for the ADR-029 multistatic mesh — procurement-gated; only pursue if a 160 MHz anchor materially helps tomography.
+
+### 2.5 Explicitly NOT adopted
+
+- No pivot toward "wireless foundation model" papers that don't ship WiFi-CSI artifacts (HeterCSI, FMCW pilot, surveys).
+- No DensePose-UV work item: the field has not demonstrated UV regression from commodity WiFi; keypoints remain our supervised target (F5).
+
+### 2.6 RuVector vendor sync + integration opportunities (added 2026-06-10)
+
+**Vendor sync record.** `vendor/ruvector` moved from pin `e38347601` (2026-05-07) to `a083bd77f` (origin/main, 3 commits past tag `ruvector-v0.2.28`; vendored workspace version 2.2.3). 111 commits in the range, roughly half NAPI-binary/lint chores. Substantive: graph condensation + differentiable min-cut (#547), core HNSW correctness fixes v2.2.3 (#502), RUSTSEC/clippy hardening (#504), ONNX embedder API-contract fix (#523/#525 — npm/TypeScript package only), dead parallel-worker import removal (#532). *Evidence: MEASURED (git range + commit-stat inspection).*
+
+**Opportunity table.** Workspace policy is crates.io versions only, so unpublished crates are WATCH by definition regardless of fit.
+
+| Crate | What it offers | wifi-densepose target | crates.io | Verdict |
+|---|---|---|---|---|

The commit states `cargo audit` returns clean across the workspace. *Evidence: MEASURED (commit message + file list). Conclusion: no pinned version has an outstanding advisory; no urgent bump required.* The NaN-sort hardening is panic-robustness hygiene our pinned 2.0.4-era crates predate, which is one more reason for the routine bumps below.
+
+**Version-bump recommendations (follow-up PR — no Cargo.toml change in this ADR):** `ruvector-mincut` 2.0.4→2.0.6, `ruvector-solver` 2.0.4→2.0.6, `ruvector-attention` 2.0.4→2.1.0, `ruvector-gnn` 2.0.5→2.2.0. Current: `ruvector-core` 2.2.0, `ruvector-attn-mincut` 2.0.4, `ruvector-temporal-tensor` 2.0.6, `ruvector-crv` 0.1.1 — all at latest published. Nothing in the sync changes §2.1.2 geometry conditioning (our `viewpoint/attention.rs` `GeometricBias` already implements the fusion mechanism) or the ADR-150 MAE recipe (training stays in tch).
+
+## 3. Consequences
+
+**Positive:** the calibration system gains the one mechanism (geometry conditioning) the 2026 literature identifies as the difference between layout-brittle and layout-robust supervised WiFi pose; ADR-150 gets a measured training recipe instead of a guessed one; we acquire two external benchmarks (WiFlow-STD, PerceptAlign dataset) to keep our claims honest.
+
+**Negative / risks:** geometry records add schema surface to banks (mitigated: optional + versioned); every adopted number is preprint-grade until our own benchmark runs land (mitigated by §2.2's no-citation rule); PerceptAlign dataset license is unconfirmed (gated); name collision risk in docs (mitigated: "WiFlow-STD (DY2434)" naming rule).
+
+**Re-check by 2026-12:** 802.11bf silicon, esp_wifi_sensing maturity (v0.1.x today), and the preprint field (newest source Apr 2026).
+
+## 4. Open questions (carried from the research run)
+
+1. Does WiFlow-STD retain accuracy when fine-tuned on ESP32-S3/C6 CSI (fewer subcarriers, lower SNR), scored on our 17-keypoint set? (§2.2 answers this.)
+   > **Partial answer (MEASURED 2026-06-11, measurement (b) on 2,046 single-room windows — `benchmarks/wiflow-std/RESULTS.md`):** pretrained init shows strong *optimization* transfer (65% PCK@20 vs scratch's 0% collapse under the same budget) but **no feature transfer** (frozen-trunk + linear adapter ≈ 0%). And no run beat the mean-pose baseline (95.9% PCK@20 — single subject, near-static normalized coords), so no CSI→pose capability is citable from this data. A definitive answer needs multi-subject/multi-position data where the mean pose is weak.
+2. Is the PerceptAlign dataset downloadable under a usable license, and does the two-checkerboard procedure work with ESP32 transceiver geometry? (§2.1.4 gate.)
+3. Will esp_wifi_sensing evolve toward 802.11bf compliance, replacing opportunistic CSI extraction?

+# ADR-153: IEEE 802.11bf-2025 Forward-Compatibility Protocol Model for wifi-densepose-hardware
+
+- **Status**: accepted
+- **Date**: 2026-06-10
+- **Deciders**: ruv
+- **Tags**: hardware, protocol, sensing, 802.11bf, forward-compatibility
+
+## Context
+
+IEEE 802.11bf-2025 (WLAN Sensing) is an **Active Standard**: board approval
+2025-05-28, published 2025-09-26 (verified against the IEEE SA record,
+<https://standards.ieee.org/ieee/802.11bf/11574/>). Its scope modifies the
+MAC, HE and EHT PHY service interfaces, plus DMG and EDMG PHYs, for WLAN
+sensing in **1–7.125 GHz** and **above 45 GHz** bands, with formal sensing
+measurement setup, measurement instance, feedback/reporting, and
+sensing-by-proxy (SBP) procedures (ADR-152 F4, evidence grade MEASURED).
+
+No commodity silicon implements the standard yet — ESP32 parts included.
+ADR-152 §2.4 therefore decided "track silicon; no code now", with RuView's
+opportunistic CSI extraction remaining the mechanism. That left a gap: when
+silicon does land, RuView would have no typed model of the standard's
+procedures to bind to, and the integration would start from zero.
+
+ADR-152 §2.4 originally classified 802.11bf as a hardware watch item with no
+implementation work until commodity silicon exposes standardized sensing
+measurements. This ADR amends that clause: OTA binding remains deferred, but
+a pure Rust protocol model, session FSM, transport seam, and opportunistic
+CSI bridge will be implemented now so RuView consumers can target a stable
+standardized sensing interface before silicon arrives.
+
+The user directed (2026-06-10) that this **forward-compatibility protocol
+model** — a protocol surface, not a conformance implementation — be built
+now.
+
+## Decision
+
+Implement an `ieee80211bf` **forward-compatibility protocol model** in
+`wifi-densepose-hardware` (pure Rust, no internal deps, simulation-testable,
+no OTA path):
+
+> This module is not a certified 802.11bf implementation. It models the
+> public procedure shape needed by RuView and RuvSense, while intentionally
+> avoiding OTA frame binding until chipset support and vendor APIs exist.
+
+1. **`types.rs`** — typed structures for the standard's sensing procedures
+   (sub-7 GHz focus; DMG stubbed): Sensing Measurement Setup (setup ID,
+   initiator/responder and transmitter/receiver roles, bandwidth,
+   periodicity, threshold-based reporting parameters), Sensing Measurement
+   Instance, Sensing Measurement Report (CSI-variant payload), SBP
+   request/response, termination. Two future-proofing requirements:
+
+   - **Version gates** — every negotiated surface is tagged with a spec
+     profile, because vendors will expose partial or renamed capabilities
+     first:
+
+     ```rust
+     pub enum SpecProfile {
+         DraftCompatible,
+         Ieee80211Bf2025,
+         VendorExtension(String),
+     }
+     ```
+
+   - **Capability negotiation** — no hardcoded ESP32 assumptions in the
+     future-silicon path:
+
+     ```rust
+     pub struct SensingCapabilities {
+         pub sub_7_ghz: bool,
+         pub dmg: bool,
+         pub edmg: bool,
+         pub csi_report: bool,
+         pub threshold_reporting: bool,
+         pub sensing_by_proxy: bool,
+         pub max_bandwidth_mhz: u16,
+         pub max_period_ms: u32,
+         pub max_active_setups: u16,
+     }
+     ```
+
+   - **Privacy and governance fields** — sensing is presence inference, not
+     just radio telemetry. Every `SensingMeasurementSetup` carries policy
+     metadata (required, not optional), for enterprise, elderly-care,
+     retail, workplace, and municipal deployments:
+
+     ```rust
+     pub enum ConsentMode {
+         LabOnly,
+         ExplicitConsent,
+         ManagedEnterprisePolicy,
+         Disabled,
+     }
+     ```
+
+2. **`session.rs`** — deterministic event-driven session state machine:
+   `Idle → SetupNegotiating → Active → Terminating → Idle`, with explicit
+   rejection paths (unsupported parameters, setup-ID collision) and timeout
+   handling.
+3. **`transport.rs`** — a `SensingTransport` trait abstracting frame
+   exchange; a `SimTransport` test double; and an `OpportunisticCsiBridge`
+   adapter mapping today's ESP32 CSI extraction onto the report path
+   (measurement instances ≈ CSI frame batches), so current hardware sits
+   behind the standardized interface. **Replaceability benchmark
+   (acceptance test):** RuvSense must consume either ESP32 opportunistic CSI
+   or future 802.11bf chipset reports through the same `SensingTransport`
+   and `SensingMeasurementReport` path, with no consumer-side rewrite — a
+   future chipset adapter replaces `OpportunisticCsiBridge` without changing
+   consumers.
+
+Constraints: input validation at boundaries (typed errors, no panics on
+adversarial input), files under 500 lines, all protocol tests runnable
+without hardware.
+
+### Acceptance checklist
+
+| Area            | Acceptance test                                                      |

+| Rejection       | Unsupported bandwidth, invalid period, duplicate setup ID            |
+| Timeout         | Negotiation timeout returns typed error and resets to Idle           |
+| Threshold       | Report emitted only when threshold condition is crossed              |
+| SBP             | Proxy request maps to responder path without direct sensor coupling  |
+| Bridge          | ESP32 CSI batch becomes standardized measurement report              |
+| Safety          | No panics on malformed inputs                                        |
+| CI              | All protocol tests run without hardware                              |
+| Maintainability | Each file under 500 lines                                            |
+
+### Non-Goals
+
+This ADR does not claim IEEE 802.11bf conformance, certification, or OTA
+interoperability. It creates a typed protocol compatibility layer so RuView
+can consume standardized sensing reports when commodity silicon exposes
+them. Vendor-specific frame exchange, firmware hooks, trigger-frame
+sounding, and certification test vectors remain future ADRs.
+
+## Consequences
+
+### Positive
+- RuView can adopt standardized WLAN sensing the day any chipset exposes
+  802.11bf measurements — the data model, session FSM, and transport seam
+  already exist and are tested.
+- The `OpportunisticCsiBridge` gives current ESP32 nodes a standardized-shape
+  interface now, decoupling RuvSense consumers from the extraction mechanism.
+- Simulation transport enables protocol-level tests in CI without hardware.
+- `SpecProfile` + `SensingCapabilities` give a clean escape hatch for the
+  partial/renamed vendor capabilities that will certainly arrive first.
+- Consent/policy metadata is structural from day one, not retrofitted.
+
+### Negative
+- Code written against a standard with zero silicon risks drift: vendor
+  implementations may interpret parameters differently; the layer may need
+  rework at first real binding (drift risk scored 7/10 at acceptance).
+- Adds maintenance surface to wifi-densepose-hardware before any
+  user-visible benefit (maintenance cost scored 3/10 — small without OTA).
+
+### Neutral
+- ADR-152 §2.4's "watch item" remains: revisit when silicon/certification
+  appears (re-check by 2026-12). This ADR changes only the "no code now"
+  clause.

+| **Deciders** | ruv |
+| **Codebase target** | `wifi-densepose-signal` (`ruvsense/`, `features.rs`, `csi_processor.rs`, `spectrogram.rs`, `bvp.rs`), benches, docs |

+
+---
+
+## 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:**

+# 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 (the ~45 not fixed here — explicit backlog)
+
+Catalogued so nothing is silently dropped. Priority: **P1** correctness-adjacent, **P2** perf, **P3** clarity/style.
+
+| # | 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 | Used as the `> TAU` ghost-tap *guard*; a correct circular variance is bounded [0,1] and would need the threshold re-derived. Semantic change — defer with a real recalibration, don't risk a silent gate regression in a perf/correctness pass. |
+| 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. |
+| 4 | features.rs ~347 | Doppler FFT planner planned once per call, reused across subcarriers | P2 | Already amortized within the call. |
+| 5 | multistatic.rs | `node_attention_weights` recomputes consensus/softmax each call; no SIMD | P2 | Needs a bench before touching; not obviously hot. |
+| 6 | tomography.rs | ISTA L1 solver re-allocates voxel buffers per solve | P2 | Bench first. |
+| 7 | pose_tracker.rs | Kalman gain matrices reallocated per update | P2 | Bench first. |
+| 8 | field_model.rs | SVD recomputed on every perturbation extract | P2 | Incremental SVD is a real project, not a micro-fix. |
+| 9 | coherence.rs / coherence_gate.rs | Z-score thresholds are magic constants, untested at boundaries | P1 | Needs labelled data to set defensible thresholds. |
+| 10 | longitudinal.rs | Welford update not numerically guarded for n=0 | P1 | Add `n>=1` guard + test (same family as §4). |
+| 11 | cross_room.rs | Fingerprint hash collisions unhandled | P2 | Low collision prob; needs design. |
+| 12 | gesture.rs | `euclidean_distance` no length-mismatch guard | P3 | Caller-enforced; add `debug_assert`. |
+| 13 | adversarial.rs | Gini/consistency thresholds are magic constants | P1 | Same labelled-data dependency as #9. |
+| 14 | cir.rs | `fft_operator` path changes the witness hash (documented) — no test that it's *numerically close* to dense | P2 | Add a tolerance test. |
+| 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 | Add iteration-cap 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 | Add boundary test. |
+| 20 | spectrogram.rs | `compute_multi_subcarrier_spectrogram` re-plans per subcarrier via `compute_spectrogram` | P2 | Hoist the planner (relates to #3). |
+| 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. |
+
+> **Horizon-ledger one-liner.** Milestone-0 DONE: dead CIR gate (FIXED+proved), NaN/inf adversarial bypass (FIXED+proved), divide-by-(n−1) window trio (FIXED+proved), calibration dead-branch (FIXED), PSD FFT-planner cache (MEASURED), DTW band (MEASURED). DEFERRED to follow-up: the ~45 findings in §7.4 (P1: phase_variance circular bug #1, Welford guard #10, threshold magic-constants #9/#13; P2/P3: the rest) — none silently dropped.
+
+---
+
+## 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` circular bug (#1) remains until it can be re-thresholded with data.
+- **Neutral:** no public API removed; `with_cir_ht20()` kept (warned); files stay scoped; new bench is additive.

+| **Scope** | Milestone 1 of the beyond-SOTA NN/training sweep: the **integrity-critical** fixes that let the training/metrics subsystem substantiate a clean accuracy claim (the unified metric, leak-free validation, honest TTA, rigorous proof), a focused set of **correctness/security** fixes, two **measured** perf wins, the NN SOTA landscape with evidence grades, and a prioritized backlog. **~45 review findings are explicitly deferred (§8)** — nothing is silently dropped. |
+
+---
+
+## 0. 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 |

+
+`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**.
+
+---
+
+## 4. Decision — TIER 3: MEASURED perf wins (new criterion benches)
+
+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** — unify the live-server torso-height PCK with `pck_canonical` (crosses the service + tch boundary).
+- **`test_metrics.rs` reference kernels** — the integration test's local `compute_pck`/`compute_oks` are independent reference impls (not production); fold them onto the canonical definition.
+- The remaining ~40 lower-severity review findings (style, micro-opt, doc) from the NN/training gap review.
+
+---
+
+## 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.

+# ADR-156: RuVector / Cross-Viewpoint Fusion Beyond-SOTA Sweep — Milestone 2 (Correctness Integrity, an Honest GDOP, Crafted-Input Safety, a Measured Hot-Path Win, and the ANN/Fusion SOTA Landscape)
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-06-11 |
+| **Deciders** | ruv |
+| **Codebase target** | `wifi-densepose-ruvector` — `viewpoint/` (`attention.rs`, `geometry.rs`, `fusion.rs`, `coherence.rs`), `mat/` (`triangulation.rs`, `heartbeat.rs`), `sketch.rs`, benches, docs |
+| **Relates to** | ADR-031 (RuView sensing-first RF mode), ADR-016/017 (RuVector integration), ADR-024 (AETHER re-ID), ADR-027 (MERIDIAN cross-env), ADR-084 (RaBitQ similarity sensor), ADR-138 (ClockQualityGate), ADR-152 (WiFi-Pose SOTA 2026 intake), ADR-154 (Signal/DSP sweep M0), ADR-155 (NN/Training sweep M1) |
+| **Scope** | Milestone 2 of the beyond-SOTA sweep: four **correctness/integrity/security** fixes on the cross-viewpoint fusion path (each pinned by a regression test that fails on the old code), one **measured** hot-path perf win + a new criterion bench, the ANN/fusion SOTA landscape graded MEASURED/CLAIMED/data-gated, and a prioritized deferred backlog. **Nothing is silently dropped.** |
+
+---
+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." Milestone 2 answers with **evidence, not adjectives** — the same contract as ADR-154/155:
+
+- Every correctness/integrity fix ships a **committed regression test that fails on the old code and passes on the new**. We verified each by reverting the fix and observing the test fail (recorded in §6).
+- Every perf number is **MEASURED before/after** with the exact reproduce command and a committed criterion bench. A perf claim without a measured before/after is **UNPROVEN** and is not made here.
+- Every external SOTA reference is graded **MEASURED** / **CLAIMED** / **DATA-GATED**, distinguishing what a paper *measured* from what it *asserts* from what our own prior measurement (ADR-152) says is **not currently the bottleneck**.
+- We disclose, in full, the **one staged finding that turned out to be a numeric no-op** (§2.1): the geometric-bias "angular wrap bug" is real as a *contract* violation but, because the bias kernel is `cos()` (even and 2π-periodic), it changes **no output value** under the current kernel. We land the fix anyway (it matches the documented contract and reuses the canonical helper) but we **do not claim a behaviour change** — that would be exactly the kind of inflation this sweep exists to prevent.
+
+Test machine for the perf numbers: Windows 11, `cargo bench --release`, criterion 0.5. Numbers are wall-clock medians on this box; the **ratio** (before/after) is the claim, not the absolute ns.
+
+Build/test gate: `cargo test --workspace --no-default-features` (the project's standard gate — no `crv`/GPU features). All fixes in this milestone are on the **default, non-feature-gated surface**, so they are fully exercised by the standard gate.
+
+---
+
+## 1. Context
+
+The cross-viewpoint fusion stack (`viewpoint/` — ADR-031) combines per-viewpoint AETHER embeddings into one fused embedding via geometric-bias attention, gated by phase coherence, with array-geometry quality scored by a Geometric Diversity Index and a Cramér-Rao bound. The `mat/` survivor-localisation helpers (`triangulation.rs`, `heartbeat.rs`) share the same crate. A beyond-SOTA review surfaced findings spanning a **mislabeled metric**, an **angular-distance contract violation**, **crafted-input panics on a network-reachable path**, and a **redundant clone in the fusion hot path**, plus an ANN/fusion SOTA-research gap. Milestone 2 closes the provable subset and grades the research landscape.
+
+---
+
+## 2. Decision — CORRECTNESS / INTEGRITY FIXES
+
+Each fix ships a regression test (all on the non-feature-gated, workspace-tested surface).
+
+### 2.1 GeometricBias angular separation — use the canonical *wrapped* distance — ACCEPTED & IMPLEMENTED (honest: numeric no-op under the current cos kernel)
+
+**The finding.** `attention::GeometricBias::build_matrix` computed the pairwise angular separation as the **raw** `|azimuth_i − azimuth_j|`. That can exceed π and mis-states the separation across the 0/2π seam (350° and 10° are 20° apart, but raw `|Δ|` = 340°). The module already had a correct wrapped helper, `geometry::angular_distance` (returns `[0, π]`), but it was **private** and `GeometricBias` did not use it.
+
+**The honest correction (disclosed, not hidden).** The bias kernel is `w_angle·cos(theta_ij)`. Because `cos` is **even and 2π-periodic**, `cos(raw) == cos(wrapped)` for every pair (verified numerically: max abs diff `1.1e-16` across seam-crossing test cases). So under the *current* kernel this "bug" produces **identical bias values** — it is a **contract violation, not a behaviour bug**. We say so plainly rather than dressing a no-op as a fix.
+
+**Why land it anyway.** (1) It makes the code satisfy its own documented contract (`theta_ij`: "angular separation in radians", which must be `[0, π]`). (2) It reuses the **single canonical** `angular_distance` helper (now made `pub`), eliminating a divergent angle computation — the same single-source-of-truth discipline ADR-155 applied to metrics. (3) It is **correct by construction** for any future non-even angular kernel (e.g. a linear `w_angle·theta_ij` penalty), which the raw-diff form would silently break.
+
+**Tests:** `geometric_bias_angular_separation_uses_wrapped_distance` (pins that a seam-crossing pair's wrapped distance is 20° while its raw `|Δ|` exceeds π, and that `build_matrix` is symmetric across the seam) and `geometric_bias_linear_angular_kernel_would_catch_raw_diff` (pins the wrapped value ∈ `[0, π]` — the invariant a future linear kernel relies on; the raw-diff form gives 190° where the wrapped form gives 170°).
+
+### 2.2 Crafted-input panics on the fusion/localisation path — typed `None` instead of panic — ACCEPTED & IMPLEMENTED (the security item)
+
+**The finding (DoS).** Two functions on a path that can carry **network-sourced multistatic frames** panicked on crafted input:
+
+- `mat::triangulation::solve_triangulation` indexed `ap_positions[0]` (panics on an empty AP table) and `ap_positions[i]` / `ap_positions[j]` (panics when a TDoA measurement references an **out-of-range AP index**). A remote peer supplying a TDoA tuple `(i=99, …)` with only 3 APs triggers an out-of-bounds panic — a remotely-triggerable denial of service.
+- `mat::heartbeat::CompressedHeartbeatSpectrogram::band_power` computed `self.n_freq_bins - 1`, which **underflows** (usize `0 − 1`) for a zero-bin spectrogram — a debug panic / release `usize::MAX` (then an out-of-range index).
+
+**The fix.** `solve_triangulation` uses `ap_positions.first()?` and `ap_positions.get(i)?` / `.get(j)?` — any empty table or out-of-range index returns `None`, never panics. `band_power` guards `n_freq_bins == 0` up front and **clamps both bounds** into `[0, last]`, returning `0.0` for empty/inverted ranges. No out-of-range index, no subtraction overflow, on any input.
+
+**Tests:** `triangulation_out_of_range_index_returns_none_no_panic`, `triangulation_empty_ap_positions_returns_none_no_panic`, `heartbeat_band_power_zero_bins_no_panic`, `heartbeat_band_power_out_of_range_bounds_no_panic`. Each **panics on the old code** (verified by reverting — §6) and returns a clean `None`/`0.0` on the new.
+
+### 2.3 GDOP mislabel — compute a real, dimensionless GDOP — ACCEPTED & IMPLEMENTED
+
+**The finding.** `geometry::CramerRaoBound` exposed a field named `gdop` ("Geometric Dilution of Precision") that was computed as `(crb_x + crb_y).sqrt()` — **identical to `rmse_lower_bound`**. That is the RMSE (metres, noise-dependent), **not** a GDOP. GDOP is a *dimensionless geometry factor* independent of the noise level; the name was a lie about the quantity.
+
+**The fix (honest rename was the fallback; real GDOP was cheap, so we computed it).** True GDOP `= sqrt(trace(G⁻¹))` where `G` is the **unit-variance** bearing-geometry matrix (the Fisher matrix with every `1/σ²` set to 1). It depends only on the array/target geometry and relates noise to position error as `rmse ≈ GDOP·σ`. We accumulate `G` alongside the FIM in both `estimate` and `estimate_regularised` (cheap 2×2), and report `INFINITY` (not NaN/panic) for a degenerate collinear geometry. The doc comment now states exactly what the field is and what it used to (wrongly) be.
+
+**Test:** `gdop_is_dimensionless_and_noise_independent` — scales every sensor's noise by 10× and asserts GDOP is unchanged while RMSE scales ~10×, and that `rmse ≈ GDOP·σ` at both noise levels. The old `gdop = sqrt(crb_x + crb_y)` **fails** this (it scaled with noise, proving it was RMSE) — verified by reverting (§6).
+
+### 2.4 `fuse()` double-clone in the aggregation hot path — eliminate the redundant clone — ACCEPTED & IMPLEMENTED (MEASURED — §4)
+
+**The finding.** `MultistaticArray::fuse` (and `fuse_ungated`) cloned every viewpoint embedding **twice** per fusion: once into the `extracted` tuple vector (`v.embedding.clone()`), then **again** when building the attention input (`extracted.iter().map(|(_, e, _, _)| e.clone())`). At the AETHER dimension (128 f32 = 512 B) over up to 8 viewpoints, that is a wholly redundant second heap allocation + memcpy per viewpoint, every TDM cycle.
+
+**The fix.** Build `extracted` once (the unavoidable clone out of the borrowed `self.viewpoints`), then **consume** `extracted` by value and **move** each embedding into the attention input (`embeddings.push(emb)`), capturing geometry/ids by `Copy` in the same pass. One clone per viewpoint instead of two. Measured win in §4.
+
+---
+
+## 3. Security review (touched files)
+
+The §2.2 crafted-input panics **are** the security item: a DoS via out-of-range indices / zero-bin underflow on a fusion/localisation path that may be driven by network-sourced multistatic frames. Beyond those, the touched files were swept for further panic-on-untrusted-input / unbounded-alloc sites:
+
+- `attention.rs` — all indexing is over internally-sized `n × n` / `d` loops bounded by validated input lengths (`DimensionMismatch` is returned for ragged embeddings); softmax denominators are floored with `f32::EPSILON`. No unbounded alloc (sizes derive from caller-supplied vector lengths already validated against `d_in`). **No further action.**
+- `geometry.rs` — `det`/`det_g` are floored before division; degenerate geometry yields `None`/`INFINITY`, never NaN-panic. **No further action.**
+- `fusion.rs` — embedding dimension is validated in `submit_viewpoint`; the event log is bounded (`max_events`, oldest-half drain). **No further action.**
+- `coherence.rs` — circular buffer is fixed-capacity; gate thresholds are clamped. **No further action.**
+
+No `unsafe`, no `unwrap()` on external input, and no unbounded allocation remain on the touched paths after §2.2.
+
+---
+
+## 4. MEASURED perf win (new criterion bench)
+
+A new bench, `crates/wifi-densepose-ruvector/benches/fusion_bench.rs`, covers the fusion hot path. It has two groups: `fusion_pipeline` (end-to-end `MultistaticArray::fuse_ungated()` at 2/4/8 viewpoints, dim 128) and an isolated A/B of the §2.4 marshalling step (`embedding_extract/before_double_clone` vs `after_single_clone`).
+
+- **Reproduce:** `cargo bench -p wifi-densepose-ruvector --bench fusion_bench`
+- **Measured (`embedding_extract`, 8 viewpoints × 128-d), medians:** `before_double_clone` **1.0029 µs** → `after_single_clone` **461.6 ns** — **~2.17× faster** on the marshalling step. The result is what theory predicts (two embedding clones collapse to one), confirming the redundant clone was the cost, not noise.
+- **End-to-end `fusion_pipeline` (medians):** 2 vp = 56.3 µs, 4 vp = 99.5 µs, 8 vp = 202.1 µs. The marshalling (~0.5–1 µs) is **well under 1%** of total fusion cost (dominated by the `n×n` attention), so the **end-to-end** effect is modest by construction; the `embedding_extract` A/B isolates and proves the clone-elimination itself. We report this honestly rather than attributing the full 2.17× to the pipeline.
+
+The double-clone elimination is also correctness-neutral: all 100 `viewpoint`/`mat` lib tests pass unchanged.
+
+---
+
+## 5. The ANN / cross-viewpoint-fusion SOTA landscape (graded)
+
+| # | Candidate | What | Grade | Verdict |
+|---|-----------|------|-------|---------|
+| **1** | **SymphonyQG** (SIGMOD 2025, public code) | Unified quantization + graph ANN; source reports **3.5–17× QPS over HNSW at equal recall**, pure-CPU / edge-portable. | **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** | Extends our existing **1-bit** `sketch.rs` (ADR-084) to multiple bits per dimension — precisely the "Pass 2" our own `sketch.rs` doc deferred (1-bit sign quantization ships first; rotation/more-bits "later if benchmark-measured top-K coverage drops below the ADR-084 90% threshold"). | **CLAIMED** (RaBitQ family well-characterised; our 1-bit baseline is MEASURED in `sketch_bench`) | **Accepted near-term.** Concrete, in-scope, incremental — extends a MEASURED capability rather than importing a new system. #2 priority. |
+| **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) — implement the `sketch.rs` "Pass 2" (more bits per dimension and/or the randomized rotation) and re-measure top-K coverage against the ADR-084 ≥90% acceptance bar in `sketch_bench`.
+- **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.

+
+---
+
+## 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: **DEFERRED, not landed** (disclosed)
+
+`secure_tdm.rs:284` compares the 8-byte HMAC tag with `self.hmac_tag == expected` (data-dependent, non-constant-time). The research authorized adding `subtle::ConstantTimeEq` **only if `subtle` were already a direct dependency** — it is not (only transitive, via a crypto crate). Per that guidance, and because this is an **8-byte tag on a LAN multistatic sync beacon** (not a remote attacker-controlled timing-oracle surface), we **do not add a direct dependency** for it. Tracked in §8 as a deferred item, not silently dropped.
+
+---
+
+## 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). | **CLAIMED-unmeasured** | **NO ACTION + corrected expectation.** The native FFI fast path is **asserted but NOT implemented** — the live scanner is the ~2 Hz netsh shim. The "10×" is unmeasured. → **ACCEPTED-FUTURE** (§8). **We explicitly do NOT claim a speedup that does not exist.** |
+
+---
+
+## 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** — `secure_tdm.rs:284` uses `==` on the 8-byte tag. Add `subtle::ConstantTimeEq` **if** `subtle` becomes a direct dependency for another reason; not worth a new dependency for an 8-byte LAN sync-beacon tag (out of the current threat model). Deferred, not dropped.
+- **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) — the asserted 10–20 Hz path is **not implemented**; the live scanner is the ~2 Hz netsh shim. Implement and **measure** the real throughput before claiming any multiple. ACCEPTED-FUTURE, CLAIMED-unmeasured until then.
+- **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.
+
+## Reproduction (MEASURED)
+
+```bash
+cd v2
+cargo test -p cog-person-count -p cog-pose-estimation -p cog-ha-matter -p ruview-swarm \
+  --no-default-features
+# ruview-swarm train path compiles (PPO autodiff)
+cargo check -p ruview-swarm --features train
+# A4 end-to-end — real signed manifest, non-null binary_sha256
+cargo run -q -p cog-person-count --no-default-features -- manifest
+```
+
+Result at time of writing (all 0 failed):
+- `cog-person-count` — **19 passed** (lib 10 incl. 3 manifest; smoke 9)
+- `cog-pose-estimation` — **8 passed** (smoke)
+- `cog-ha-matter` — **64 passed** (unchanged; description-only edit)
+- `ruview-swarm` — **117 passed** (default features); `--features train` compiles clean.
+
+Scope was limited to the four named crates. NO-ACTION positives (witness chain,
+fusion, PPO + randn audit) were verified by inspection and left untouched.

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

+- **Amends**: ADR-159 (deferred-backlog line for wasm-edge now TRUE)
+
+## 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.
+
+## Per-prefix classification
+
+| Prefix | Class | Note |
+|--------|-------|------|
+| `sig_*` (signal intelligence) | **REAL-DSP, honest** | Algorithm-named (flash-attention, sparse-recovery, optimal-transport, temporal-compress, mincut). Names describe the math, not an overclaimed outcome. NO-ACTION on labels; A5 soundness applied. |

+
+## 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** — **DATA-GATED**. Validating any med_*/affect/
+  sign-language claim requires labelled clinical/affective/ASL data and reference
+  standards that do not exist in this repo. The disclaimers + feature gate are the
+  honest stand-in. Nothing is claimed that is not measured.
+- **Criterion benches for `process_frame` budget claims** — **ACCEPTED-FUTURE**.
+  `tests/budget_compliance.rs` asserts L/S/H tier wall-clock budgets (25 tests,
+  passing), but a regression-grade criterion bench is not yet wired.
+- **`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.

+- **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).

+# RuView HOMECORE vs Home Assistant — Performance & Capability Benchmark
+
+**Measured:** 2026-05-31 · Windows 11, Docker Desktop 28.5.1 (WSL2 Linux engine) · single host.
+**Reproduce:** `python aether-arena/staging/run_homecore_bench.py` and `python aether-arena/staging/run_ha_bench.py`.
+
+HOMECORE is RuView's **wire-compatible Rust port of Home Assistant's core** (ADR-125…ADR-134): the
+same `/api` REST + WebSocket surface, the same SQLite recorder schema, an automation engine, a
+HomeKit bridge, a WASM plugin runtime, and a voice/assist pipeline — plus **native WiFi/RF sensing
+entities** (presence, breathing, heart-rate, pose) that Home Assistant can only get through external
+add-ons. Because the API is wire-compatible, the two can be measured head-to-head on the same client.
+
+> **Read this honestly.** HOMECORE (`0.1.0-alpha`) is a young, focused core; Home Assistant is a
+> mature platform with ~3,000 integrations and a decade of ecosystem. HOMECORE's thesis is **not**
+> "more features" — it is **the same control plane at 1/35th the memory and 18× the startup speed,
+> with RF sensing built in.** The numbers below quantify exactly that trade.
+
+## Performance (measured)
+
+| Metric | RuView HOMECORE `0.1.0-alpha` | Home Assistant `stable` | Advantage |
+|--------|------------------------------:|------------------------:|-----------|
+| **Cold start → API/web ready** | **0.55 s** | 9.72 s | **18× faster** |
+| **Idle resident memory (RSS)** | **10.1 MB** | 359 MB | **35× leaner** |
+| **Distribution size** | **4.7 MB** (single static binary) | 610 MB (container image) | **130× smaller** |
+| **Idle CPU** | 0.0 % | 0.0 % | tie |
+| **REST latency p50** | 2.13 ms | 2.95 ms | comparable¹ |
+| **REST latency p95** | 22.9 ms | 27.3 ms | comparable¹ |
+| **REST latency p99** | 26.2 ms | 28.3 ms | comparable¹ |
+| **REST throughput (1 conn, sequential)** | **1,599 req/s** | 716 req/s | **2.2×** |
+| **Recorder DB after boot** | 36.9 KB | 4.1 KB | — (HOMECORE seeds 10 demo entities + history) |
+| **Process threads (idle)** | 22 | n/a (containerized Python) | — |
+
+¹ **Latency caveat — read before quoting.** The two latency rows are *not* the same endpoint.
+HOMECORE is measured on **authenticated `/api/states`** (returns 10 live entities). Home Assistant's
+`/api/*` requires a completed onboarding flow + long-lived access token, so HA is measured on the
+**unauthenticated `/manifest.json`** served by the same aiohttp stack. Both are single-connection,
+300-sample, sequential. Treat latency as "same order of magnitude"; treat **memory, startup, and
+size as the decisive, apples-to-apples results.** Throughput is endpoint-confounded the same way —
+the 2.2× is directional, not a controlled isolate.
+
+### What the deltas mean in practice
+- **10 MB vs 359 MB RSS:** HOMECORE runs comfortably on a Pi Zero 2 W or an ESP32-class gateway
+  alongside the sensing pipeline; HA effectively needs a Pi 4/5 or x86 to itself.
+- **0.55 s vs 9.7 s start:** HOMECORE can be cold-started per-request or restarted on config change
+  without a noticeable outage; HA's ~10 s boot (longer with real integrations) makes it a
+  long-lived daemon only.
+- **4.7 MB vs 610 MB:** OTA-updating the whole control plane over a metered/rural link is trivial
+  for HOMECORE; HA ships as a ~250 MB compressed image.
+
+## Capability & feature comparison
+
+| Capability | RuView HOMECORE | Home Assistant |
+|-----------|-----------------|----------------|
+| HA-compatible REST `/api` | ✅ wire-compatible subset (ADR-130) | ✅ reference implementation |
+| HA-compatible WebSocket API | ✅ (ADR-130) | ✅ |

+### Where each wins
+- **HOMECORE wins:** resource footprint, cold-start, distribution size, throughput-per-MB, memory
+  safety, sandboxed (WASM) plugins, and — uniquely — **WiFi/RF sensing as native entities**. Ideal
+  for edge gateways, battery/solar nodes, and shipping the control plane *with* the sensor.
+- **Home Assistant wins:** integration breadth, UI/dashboard maturity, add-on ecosystem, community
+  support, and production track record. Ideal as a full-house hub on a Pi 4/5+ or x86.
+
+## Honest summary
+
+For the **shared, wire-compatible HA control plane**, HOMECORE delivers it at **~35× less RAM,
+~18× faster startup, and ~130× smaller footprint**, with WiFi sensing built in and HA-config
+migration on the way. What it does **not** yet match is Home Assistant's enormous integration
+catalog and UI maturity. The right read is **"HA-compatible core, edge-class resource budget,
+RF-native"** — not "HA replacement." For a sensing node that also needs to *be* a smart-home hub,
+HOMECORE's efficiency is decisive; for a feature-complete whole-home hub today, Home Assistant
+remains the broader platform.
+
+## Reproduction & method
+
+- **HOMECORE:** `v2/target/release/homecore-server.exe` (`0.1.0-alpha.0`), bound to `127.0.0.1:8124`,
+  SQLite file recorder, dev-token auth (`Authorization: Bearer …`). Startup = `Popen` → first `200`
+  on `/api/`. RSS/CPU via `psutil` after a 2 s settle. 300-sample sequential latency on `/api/states`.
+- **Home Assistant:** `ghcr.io/home-assistant/home-assistant:stable` in Docker, `-p 8125:8123`,
+  fresh `/config`. Startup = container start → first `<500` on `/manifest.json`. RSS/CPU via
+  `docker stats --no-stream` after a 20 s settle. 300-sample sequential latency on `/manifest.json`.
+- Both runs are single-host, single-connection, no concurrency tuning. Numbers are indicative of
+  the **resource/startup class**, which is the property that differs by orders of magnitude;
+  latency/throughput are reported with the endpoint caveat above and should not be over-read.

+# WiFi-CSI Sensing on MM-Fi — a complete, honest study
+
+**Scope:** what works, what doesn't, and what actually ships — for 2D human **pose** and **action
+recognition** from WiFi Channel State Information on the public [MM-Fi](https://github.com/ybhbingo/MMFi_dataset)
+benchmark (40 subjects × 4 environments, 27 activities, `[3 antennas, 114 subcarriers, 10 frames]`
+CSI amplitude). All numbers measured on an RTX 5080; reproduction scripts referenced throughout.
+
+> **One-line takeaway:** we beat published pose SOTA *and* shrank it to a 20 KB edge model, but the
+> deeper result is that **WiFi sensing doesn't generalize zero-shot to new people/rooms — and a
+> ~30-second in-room calibration fixes that completely, for *both* tasks.** Few-shot calibration, not
+> zero-shot invariance, is the deployment answer.
+>
+> **Sharpest finding (§7):** WiFi-CSI sensing is largely a **random-features + target-trained-readout**
+> problem — a *random frozen* encoder + a trained head gets within ~2–4 pts of a fully-trained encoder
+> (and within <2 pts cross-subject). The encoder barely learns anything transferable; the signal is in
+> the readout. This single fact explains the zero-shot collapse, the no-transfer results, the
+> foundation-encoder failure, *and* why per-room calibration works.
+
+## 1. Pose estimation
+
+### 1.1 In-domain accuracy (beats SOTA)
+Metric: torso-normalized PCK@20 (MultiFormer's definition). Protocol: MM-Fi `random_split` (the
+dataset default).
+
+| Model | torso-PCK@20 |
+|-------|-------------:|
+| CSI2Pose (prior) | 68.41% |
+| MultiFormer (prior SOTA, 2025) | 72.25% |
+| **Ours (single)** | **82.69%** |
+| **Ours (graph + 3-ensemble + TTA)** | **83.59%** |
+
+Architecture: linear projection → 4-layer/8-head Transformer over the 10 temporal tokens →
+**temporal attention pooling** (the single biggest lever) → MLP head → skeleton-graph refinement.
+The headline was *self-corrected down* from an inflated 91.86% (loose bbox normalization) to 82.69%
+under the matched torso metric before publishing.
+
+### 1.2 Efficiency frontier (beats SOTA at a fraction of the size)
+Every model from `micro` (75 K params) up is **Pareto-dominant** — smaller *and* more accurate than
+prior SOTA. A **75 K-param model tops MultiFormer**; deployed **int4 is ~20 KB at 74.08% (QAT)**,
+0.135 ms single-thread CPU. (int8 is lossless at 74.7%; naïve int4 PTQ drops to 70.2% — QAT recovers
+it.) Full curve: [`wifi-pose-efficiency-frontier.md`](wifi-pose-efficiency-frontier.md).
+Published: [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose).
+
+## 2. Action recognition (27 classes)
+
+MM-Fi's own paper **does not benchmark WiFi-CSI action recognition** (its HAR is skeleton-based,
+RGB/LiDAR/mmWave only). The only published WiFi-CSI-on-MM-Fi number is WiDistill (2024): 34.0%
+(ResNet-18, unspecified split). We establish:
+
+| Protocol | top-1 |
+|----------|------:|
+| random_split (in-domain) | 88.08% |
+| cross-subject (official), zero-shot | **10.0%** (near-chance) |
+
+The 88% is **leakage-inflated** (see §3); the honest cross-subject zero-shot is ~10%.
+
+## 3. The generalization story (the real result)
+
+Random-split numbers are inflated by temporal/subject adjacency. Under leakage-free protocols, WiFi
+sensing **collapses**:
+
+| Task | in-domain | cross-subject (zero-shot) | cross-environment (zero-shot) |
+|------|----------:|--------------------------:|------------------------------:|
+| Pose | 83.6% | 64% | ~10% |
+| Action | 88.1% | 10% | — |
+
+### 3.1 What does NOT close the gap (all measured, all negative)
+- **CORAL** (deep feature-cov alignment): no cross-subject gain; only marginal on cross-env (~17%).
+- **DANN** (subject-adversarial): ~0, loss-imbalance fragile.
+- **Per-antenna instance-norm + SpecAugment**: −4.6 (destroys cross-antenna pose structure).
+- **Pose-contrastive foundation pretraining**: −2.3 — and the SupCon loss *never left the `ln(B)`
+  random floor*, i.e. same-pose CSI is **not contrastively alignable across subjects**: the invariance
+  the objective wants isn't present in the data.
+- **Knowledge distillation** (flagship→tiny): no gain; direct training wins.
+- **More training subjects**: saturates — 4→8 subjects = +21 pts, but 24→32 = +0.45 pts (asymptote ~64%).
+
+Only **mixup + TTA + ensemble** helps cross-subject, and by <1 pt. The gap is *fundamental
+distribution shift*, not a tunable/algorithmic gap.
+
+### 3.2 What DOES close it: few-shot in-room calibration
+A handful of labeled frames from the actual deployment room recovers most of the gap — and the
+*biggest* zero-shot gap gives the *biggest* gain (an unseen room is one coherent shift a few frames
+pin down):
+
+| Calibration samples/subject | Pose cross-subj | Pose cross-env | Action cross-subj |
+|----------------------------:|----------------:|---------------:|------------------:|
+| 0 (zero-shot) | 64% | ~10% | 10% |
+| 5 | — | **60%** | 13% |
+| 50 | 70% | 70% | 36% |
+| 200 | 76% | 73% | 59% |
+| 1000 | 78% | 75% | 76% |
+
+**Confirmed task-general:** the identical pattern holds for pose regression *and* 27-class action
+classification. Few-shot in-room calibration is the **universal** WiFi-sensing deployment mechanism.
+(Action needs more calibration than pose — classification vs regression.)
+
+### 3.3 Deployable as a ~11 KB adapter
+Full fine-tune means a 2.3 MB model copy per room. A **rank-8 LoRA adapter (~11 KB)** recovers most
+of the gain (cross-subject 64→72.5% at 0.5% the size). Calibration data budget: **~100–200 labeled
+samples** (knee at ~50 → 70%; below ~20 it can hurt).
+
+| Calibration method @200 samples | PCK@20 | adapter |
+|---------------------------------|-------:|--------:|
+| LoRA rank-8 | 72.5% | ~11 KB |
+| head + graph only | 72.7% | 119 KB |
+| frozen-trunk | 73.5% | 207 KB |
+| full finetune | 76.2% | 2.3 MB |
+
+## 4. The calibration service (shipped)
+
+The mechanism is implemented end-to-end: a Python reference
+([`aether-arena/calibration/`](../../aether-arena/calibration/) — `calibrate.py` fits an adapter from
+a labeled clip, verified 3.09%→74.29% on an unseen MM-Fi room) **and** in the Rust product engine
+(`cog-pose-estimation`: `InferenceEngine::with_adapter()`, `run --adapter <room.safetensors>`,
+architecture-agnostic LoRA on the pose head, tested).
+
+## 5. Honest limitations
+
+- Most generalization numbers are within MM-Fi (one dataset, one hardware setup). **Cross-*dataset***
+  transfer was tested against **NTU-Fi HAR** (same 3×114 layout, different lab/hardware/rooms): an
+  MM-Fi-trained representation does **not** transfer beneficially — a frozen MM-Fi trunk probes NTU-Fi
+  at 91.5%, *no better than random features* (93%), and full fine-tuning (75%) underperforms a linear
+  probe. CSI representations are **distribution-locked** (same root cause as the within-MM-Fi
+  cross-subject/-environment collapse); the practical answer is on-target training/few-shot, not
+  transferable zero-shot features. Caveat: NTU-Fi's 6 coarse activities are an *easy* target (random
+  features → 93%), so it weakly stresses representation quality — but re-running on the harder
+  **NTU-Fi-HumanID** task (14-class gait person-ID, chance 7.1%) gave the *same* result (MM-Fi
+  pretrain 91.7% ≈ random 92.8%). **Unified root cause:** for CSI, in-domain classification lives in
+  the *target-trained readout* (a random 256-d projection of 3,420-d CSI is already linearly
+  separable), while the *learned representation* fails to transfer across subjects, rooms, and
+  datasets alike. WiFi-CSI sensing is **distribution-locked**; the answer is on-target few-shot
+  calibration, not transferable features. A harder cross-dataset *pose* benchmark (vs classification)
+  remains the one open variant.
+- Random-split numbers are reported only to compare to prior work on the same protocol; they are
+  in-domain and partly leaky. The cross-subject / cross-environment numbers are the honest ones.
+- Action-recognition accuracy is window-level (MM-Fi's own HAR experiment is clip-level); not directly
+  comparable to sequence-level reports.
+- On-device (ARM/Hailo) latency is pending hardware; CPU latency (0.135 ms x86 single-thread) is the
+  current proxy.
+

+
+Pose: `aether-arena/staging/train_save.py` (flagship), `train_efficiency_pareto.py`,
+`quant_micro.py`, `train_fewshot_adapt.py`, `train_adapter_calib.py`. Action: `train_action.py`,
+`train_action_fewshot.py`. Calibration service: `aether-arena/calibration/`. Decision record + full
+empirical chain: [ADR-150 §3.2–3.6](../adr/ADR-150-rf-foundation-encoder.md). Leaderboard + witness
+ledger: [AetherArena](https://huggingface.co/spaces/ruvnet/aether-arena) (ADR-149).
+
+## 7. The sharpest result: the encoder barely matters
+
+A random *frozen* transformer encoder + a trained pose head matches a fully-trained encoder to within
+2–4 points (cross-subject: <2 points):
+
+| Pose protocol | fully-trained encoder | random-frozen encoder + head |
+|---------------|----------------------:|-----------------------------:|
+| in-domain | 78.2% | 73.8% |
+| cross-subject | 63.9% | 62.1% |
+
+(Same fair-comparison config; absolute numbers below the 83.6% flagship — the *delta* is the point.)
+**Almost all the task signal lives in the readout** (pose head + skeleton-graph refinement on a
+random high-dim CSI projection), not in the learned encoder. This is the unifying explanation for the
+whole study: there is barely a *learned representation* to transfer (hence the cross-subject/-env/
+-dataset collapses and the foundation-encoder failure), and per-room calibration works precisely
+because it re-fits the readout where the signal is. **Practical upshot:** for WiFi-CSI sensing, spend
+compute on the readout + per-room calibration, not on expensive encoder pretraining. Reproduce:
+`aether-arena/staging/train_pose_randomfeat.py`.

+# WiFi-CSI Pose — Efficiency Frontier (beyond SOTA at a fraction of the size)
+
+**Measured:** 2026-05-31 · MM-Fi `random_split` (ratio 0.8, seed 0) · RTX 5080 · torso-normalized
+PCK@20 (MultiFormer Table VII metric: `‖pred−gt‖ ≤ 0.2·‖R-shoulder − L-hip‖`).
+
+The flagship [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)
+reaches **83.59%** torso-PCK@20 (vs MultiFormer 72.25%, CSI2Pose 68.41%). But the headline number
+isn't the whole story for **edge deployment** — on a Raspberry Pi / ESP32-class target, *params and
+latency* matter as much as accuracy. So we swept model size to map the **accuracy-per-parameter
+frontier**: how small can a WiFi-CSI pose model be and still beat the prior published SOTA?
+
+## The frontier
+
+| Model | Params | Latency (batch=1) | torso-PCK@20 | vs SOTA (72.25%) |
+|-------|-------:|------------------:|-------------:|------------------|
+| nano  | 39,971 | 0.126 ms | 71.76% | −0.49 (58× smaller than flagship) |
+| **micro** | **75,237** | 0.224 ms | **74.30%** | **✅ +2.05 — beats SOTA at 31× fewer params** |
+| tiny  | 210,949 | 0.299 ms | 76.82% | ✅ +4.57 |
+| small | 348,005 | 0.287 ms | 77.87% | ✅ +5.62 |
+| base  | 726,437 | 0.344 ms | 79.38% | ✅ +7.13 (3.2× smaller) |
+| flagship | 2,320,869 | — | 83.59% | +11.34 |
+
+**Every configuration from `micro` (75K params) upward beats the prior published state of the art**,
+and even `nano` (40K params, 0.13 ms) lands within half a point of it — at ~1/58th the flagship's
+parameter count. A **75,237-parameter** model tops MultiFormer's 72.25%.
+
+### Deployable footprint AND deployed accuracy (quantized `micro`)
+
+Size alone isn't the claim — what matters is **accuracy at the deployed precision**. Measured
+(weight-only, per-tensor symmetric):
+
+| Precision | Size | torso-PCK@20 | vs SOTA 72.25 |
+|-----------|-----:|-------------:|---------------|
+| fp32 | 294 KB | 74.73% | ✅ +2.5 |
+| **int8 (PTQ)** | **73.5 KB** | **74.70%** | ✅ +2.5 — **essentially lossless** |
+| int4 (naïve PTQ) | 36.7 KB | 70.21% | ❌ −2.0 — drops below SOTA |
+| **int4 (QAT)** | **36.7 KB** | **74.46%** | ✅ **+2.2 — recovered, still beats SOTA** |
+
+**The honest edge result:** `micro` is **lossless at int8 (73.5 KB, 74.70%)**, and at **int4 (36.7 KB)
+naïve post-training quantization falls below SOTA (70.21%) — but quantization-aware training fully
+recovers it to 74.46%**, still beating MultiFormer. So a **SOTA-beating WiFi-pose model genuinely runs
+in ~37 KB int4** (with QAT) or **~73 KB int8** (no retraining) — deployable on the sensing node itself.
+`nano` (40K params) sits at the SOTA line in fp32 and is best treated as int8.
+
+(We also tested flagship→tiny **knowledge distillation**: it did *not* help — the tiny students reach
+equal or higher accuracy from ground truth alone, so regression-KD on keypoints only adds teacher
+noise. Direct training wins.)
+
+**Shipped as a usable artifact.** The int4-QAT `micro` model is published and downloadable at
+[`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose/tree/main/edge)
+(`pose_micro_int4.npz` + `load_int4.py`): **verified deployed int4 accuracy 74.08%** (beats SOTA),
+~20 KB int4 weight payload, sha256 `c03eeb…`. It runs in **0.135 ms single-thread on x86 CPU**
+(no GPU) — i.e. real-time pose with no accelerator; a Raspberry-Pi-class ARM core would be slower
+but still comfortably real-time. (Latency measured on ruvultra x86; on-device ARM validation pending
+the Pi fleet coming back online.)
+
+## Why this matters
+
+- **Edge-native pose.** `micro`/`tiny` (75–210K params, sub-0.3 ms on a discrete GPU) are small
+  enough to quantize and run on a Pi-class / Hailo edge node next to the sensing pipeline — no cloud
+  round-trip, no camera.
+- **Pareto-dominant, not just smaller.** These aren't accuracy-traded-for-size compromises *below*
+  SOTA; they are simultaneously **smaller than MultiFormer and more accurate than it**.
+- **Orthogonal to the accuracy frontier.** Unlike cross-subject/cross-environment generalization
+  (which is data-bound — see [ADR-150 §3.2](../adr/ADR-150-rf-foundation-encoder.md)), the efficiency
+  frontier responded immediately to optimization. This is the lever that's still open.
+
+## Method & reproduction
+
+Same architecture family as the flagship — input `[3,114,10]` CSI amplitude → linear projection →
+`L`-layer / `H`-head Transformer encoder over the 10 temporal tokens → **temporal attention
+pooling** → MLP head → **skeleton-graph refinement** (COCO bone topology) — with width `d`, depth
+`L`, heads `H` swept. Training: mixup (Beta(0.2,0.2)), 4-view test-time augmentation, EMA, cosine LR.
+
+| Model | d | L | H | graph head |
+|-------|--:|--:|--:|:----------:|

+| micro | 64 | 1 | 2 | ✓ |
+| tiny | 96 | 2 | 4 | ✓ |

+same param/accuracy ordering.
+
+> **Controlled claim.** In-domain `random_split` (the dataset's documented default) — the same

+
+"Teach the room before you teach the model." A local-first pipeline that turns a few minutes of
+clean human anchors — layered on an empty-room baseline — into a versioned **bank of small,
+room-calibrated specialists** for presence, posture, breathing, heartbeat, restlessness, and anomaly.

+```
+
+**Design invariants (carry these into the appliance):**
+- **Specialisation over scale** — six tiny models (threshold / nearest-prototype / autocorrelation), not one big model. They run in microseconds on a Pi CPU; **they do not need the Hailo HAT**.
+- **Local-first** — baselines + per-room banks stay on the device. Cross-room sharing is *model deltas* (federation, ADR-105), **never raw CSI**.
+- **Honest degradation** — baseline drift marks a bank `STALE`; a physically-implausible window is vetoed rather than emitting a hallucinated reading.

+
+> The appliance's WiFi (`wlan0`) is `managed` with no nexmon — **the Pi is a CSI *processor*, not a CSI radio.** CSI arrives from the ESP32 nodes (the existing `ruview-vitals-worker:50054` already receives it). Calibration *consumes* that stream; it does not sense directly.

+## 4. HTTP API — `calibrate-serve` (CORS-enabled; this is what a UI/appliance drives)
+
+| Method | Path | Body / returns |
+|--------|------|----------------|
+| GET | `/api/v1/calibration/health` | `{ udp_port, frames_seen, last_frame_age_ms, streaming, default_tier, output_dir, session_active }` |
+| POST | `/api/v1/calibration/start` | `{ tier?, duration_s?, room_id?, min_frames? }` → `202` session snapshot |
+| GET | `/api/v1/calibration/status` | live `{ state, frames_recorded, target_frames, progress, z_median, eta_s, ... }` |
+| POST | `/api/v1/calibration/stop` | finalize early → result summary |
+| GET | `/api/v1/calibration/result` | last finalized baseline summary |
+| GET | `/api/v1/calibration/baselines` | list persisted `.bin` baselines |
+| GET | `/api/v1/room/state?bank=<name>` | **live RoomState** (mixture-of-specialists over the CSI window; bank resolved as a sanitized name under `output_dir`) |
+| POST | `/api/v1/room/train` | `{ room_id, baseline_id, anchors[]? }` → train + persist a specialist bank as `<output_dir>/<room_id>.json` (anchors[] optional if enrolled via `/enroll/anchor`; read back via `/room/state?bank=<room_id>`) |
+| POST | `/api/v1/enroll/anchor` | `{ room_id, baseline, label, duration_s? }` → capture one guided anchor against a baseline (blocks for the capture); returns the gate verdict + progress |
+| GET | `/api/v1/enroll/status?room=<id>` | enrollment progress (accepted anchors, next, complete) |
+
+A single background task owns the UDP socket + recorder (handlers talk to it over an mpsc channel +
+shared status snapshot), so the API is non-blocking. **The full pipeline is now drivable over HTTP** — baseline (`start`/`stop`) → `enroll/anchor` (×8) → `room/train` → `room/state` — so the appliance UI needs no CLI. (The CLI `enroll`/`train-room`/`room-watch` remain for scripted/headless use.)
+
+---
+
+## 5. Public crate API (`wifi-densepose-calibration`)
+
+```rust
+// Stage 2 — enrollment
+anchor::{AnchorLabel, Anchor, AnchorQuality, EnrollmentEvent, EnrollmentSession, Posture}
+enrollment::{AnchorQualityGate, AnchorRecorder}
+// Stage 3 — features
+extract::{Features, AnchorFeature, autocorr_dominant}
+// Stage 4 — specialists + bank
+specialist::{Specialist, SpecialistKind, SpecialistReading,
+             PresenceSpecialist, PostureSpecialist, BreathingSpecialist,
+             HeartbeatSpecialist, RestlessnessSpecialist, AnomalySpecialist}
+bank::SpecialistBank
+// Stage 5 — runtime
+runtime::{MixtureOfSpecialists, RoomState}
+multistatic::MultiNodeMixture            // fuse co-located nodes (ADR-029)
+```
+Pure Rust; deps are `wifi-densepose-core` + `wifi-densepose-signal` (default-features off) + serde/uuid.
+**No GPU / no system BLAS** in the calibration path → builds cleanly on aarch64.
+
+---
+
+## 6. Appliance integration plan (`cognitum-one/v0-appliance`)
+
+Verified on `cognitum-v0`: aarch64, `cargo 1.96.0`, Hailo `HAILO10H`, `ruview-vitals-worker:50054`.
+
+**Step 1 — vendor / depend on the crate.** Add `wifi-densepose-calibration` (path or published crate)
+to the appliance workspace. It builds natively on aarch64 — no BLAS/GPU, **and no ONNX/OpenSSL**:
+the CLI's `mat`→`nn`→`ort`(ONNX)→`openssl-sys` chain is now feature-gated out of the calibration build.
+
+```bash
+# Pi/appliance calibration binary — cross-compiles clean (no ort/openssl):
+cargo build -p wifi-densepose-cli --no-default-features --release
+#   (omit `--no-default-features` only if you also need the MAT subcommands)
+```
+Verified: `cargo tree -p wifi-densepose-cli --no-default-features` shows **0** `ort`/`openssl-sys` deps;
+`cross test --target aarch64-unknown-linux-gnu` passes the calibration suite under qemu.
+
+**Step 2 — wire the CSI source.** Two options:
+  - (a) Tee the ESP32 UDP stream the vitals worker already receives into the calibration ingest, or
+  - (b) point ESP32 nodes (`edge_tier=0`) at the appliance's calibration UDP port directly.
+  Reuse `parse_csi_packet` (or the rvCSI `CsiFrame` schema if you normalise upstream).
+
+**Step 3 — run the calibration service.** Either embed the crate (call `CalibrationRecorder` /
+`MixtureOfSpecialists` in-process from a worker like `ruview-vitals-worker`), or run the
+`calibrate-serve` binary as a sidecar (systemd unit, bind `127.0.0.1` + reverse-proxy through the
+appliance gateway on `:9000`). Persist baselines/banks under the appliance data dir, keyed by `room_id`.
+
+**Step 4 — expose to the dashboard.** Surface the `/api/v1/calibration/*` endpoints (and add
+`enroll`/`train`/`room-state` endpoints — small additive work) behind the appliance's bearer-token
+auth + the existing `Seeds`/`Edge` nav. `RoomState` (§3.5) is the live readout payload.
+
+**Step 5 — (optional) Hailo backbone tier.** Compile the ADR-150 RF Foundation Encoder + neural pose
+head to Hailo HEF, serve via `ruvector-hailo-worker:50051`; the small specialists become heads over its
+embedding. This is the ADR-150 follow-on — *not required* for the calibration service to run.
+
+**Privacy / security:** keep baselines + banks local; if federating across appliances (ADR-105),
+exchange bank/model deltas, never raw CSI. Hardening already in place:
+- **`--token <T>`** (or `CALIBRATE_TOKEN` env) requires `Authorization: Bearer <T>` on every route; the
+  server warns loudly if bound to a non-loopback address without a token.
+- **`room_id` is sanitized** to `[A-Za-z0-9_-]` (≤64 chars) before it touches the baseline write path —
+  no `../` / absolute-path traversal.
+- CORS is permissive for dev — in production bind to loopback and reverse-proxy through the appliance
+  gateway (which already enforces bearer auth).
+
+---
+
+## 7. Status & validation
+
+- **Implemented:** all 5 stages + multistatic fusion; CLI + Stage-1 HTTP API (auth + path-traversal hardened). **55 tests** (35 calibration unit + 1 full-loop integration + 19 CLI), all passing under qemu-aarch64.
+
+**Precise validation matrix (don't overstate this — no clean full calibration has run on-target yet):**
+
+| Stage | Pi-5 (real nexmon→`0xC5110001`, 6,813 frames) | ESP32-S3 (COM8, `edge_tier=0`) | qemu / unit / integration |
+|---|---|---|---|
+| baseline capture + HTTP API + **auth gate** | ✅ | ✅ (120-frame) | full-loop ✅ |
+| **clean** empty-room baseline | ❌ `motion_flagged` (artifact) | ❌ (occupied) | full-loop ✅ (synthetic, zero motion flags) |
+| enroll → train-room | ❌ | ❌ (needs operator poses) | full-loop ✅ (8/8 anchors, 6 specialists, JSON round-trip) |
+| runtime infer | ❌ on-target | ◐ single-node breathing ~16–31 BPM via the **stateless** head (not a trained bank) + node-id fusion | full-loop ✅ (trained bank: 18±2 BPM positive, absent negative, foreign-baseline STALE) |
+
+The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`wifi-densepose-calibration/tests/full_loop.rs` — drives the CLI's exact stage order through the public API, seed-robust across 5 seeds, runs with and without default features). Capture + API + auth are proven on real CSI (both boxes). What remains is strictly the **on-target** run: real CSI, a physically empty room for baseline, and an operator performing the 8 guided anchors — that hardware session is the last open item.
+
+- **Known follow-ups (appliance backlog):** `--source-format adr018v6` to drive calibration from the Pi's own nexmon (no ESP32/transcoder); the on-target clean-room enroll→train→infer session (above); phase-based (vs mean-amplitude) breathing carrier; RVF/HNSW persistence (currently JSON); enroll/train HTTP endpoints (live `/room/state` already added); ADR-150 Hailo backbone; true 2-node multistatic; ADR-105 federation.
+- **Behavioral findings from the full-loop test — all four FIXED pre-hardware-session:** (1) *z-band squeeze* — anchor motion is now measured from frame-to-frame deltas of the deviation series (`|Δz| > 0.5 ∨ |Δφ| > π/6`), not from the absolute `motion_flagged` (which conflated presence strength with motion); a strongly-reflecting still person (z = 3.0, every frame flagged by the old heuristic) now enrolls — regression-guarded in the full-loop test's `StandStill` anchor and `enrollment::tests`. (2) *Variance-only presence* — `PresenceSpecialist` gained a mean-shift channel (|mean − empty mean| vs a trained threshold); a motionless person is detected via the mean even at empty-level variance — regression-guarded in the full-loop motionless-person case; old persisted banks deserialize with the channel inert (variance-only behavior preserved). (3) *Ungated hz embedding* — `Features::embedding()` zeroes `breathing_hz`/`heart_hz` below `EMBED_MIN_SCORE` (0.25), keeping noise-window random frequencies out of the prototype space. (4) *Heart-band leakage* (found while fixing 3): a strong breathing rhythm's autocorrelation leaks into the HR band as a high-score lag-floor edge value (e.g. score 0.67 at 3.33 Hz from a pure 0.30 Hz breath); `autocorr_dominant` now requires the winning lag to be an interior local maximum, rejecting band-edge leakage while preserving true in-band peaks.

+# Proof of Capabilities — answering the "it's fake / misleading" claims
+
+**Short version: don't trust us — verify.** Every claim below comes with a command you can
+run yourself in minutes. Where early versions of this project over-claimed, we say so plainly
+and point at exactly what changed. This page exists because skepticism is the correct default
+for a project that says "WiFi can sense people," and the only honest answer to that skepticism
+is reproducible evidence, not assertion.
+
+---
+
+## 1. What people have said
+
+This project (and the broader "DensePose From WiFi" idea) went viral and drew sharp, often
+fair, criticism. The most pointed claims:
+
+- **"AI-generated facade / vibe-coded boilerplate"** — that the repo is scaffolding with the
+  core signal-processing and pose pipeline unimplemented. ([Hacker News](https://news.ycombinator.com/item?id=46388904),
+  [Cybernews](https://cybernews.com/security/viral-github-project-wifi-see-through-walls/))
+- **"Fake CSI data"** — that the Python extractor returned random arrays instead of real
+  hardware data (e.g. `csi_extractor.py` returning random amplitude/phase). ([audit fork](https://github.com/deletexiumu/wifi-densepose))
+- **"No trained models, fabricated metrics"** — that headline numbers like "94.2% pose
+  accuracy," "96.5% fall sensitivity," "100% presence/coverage" had no trained weights or
+  evaluation behind them.
+- **"Star inflation"** and **"defensive, not demonstrative, responses"** to criticism.
+- **"Reads like ad copy"** — emoji-heavy AI documentation that conveys little.
+
+We take these seriously — but most of them mistook an **early-but-functional prototype** for a
+non-functional facade. The original release worked: it had a real, deterministic signal-processing
+pipeline (provable in 30 seconds, §4 Step 1) and a runnable end-to-end demo. What it *also* had,
+like every sensing tool, was a **simulate / no-hardware mode** so you can run it without a NIC —
+and a few genuinely over-stated headline metrics. The audit conflated the simulate fallback with
+fraud and the missing model weights with a missing pipeline. Here is the honest accounting, then
+the proof.
+
+---
+
+## 2. What was fair, and what was not
+
+The original release was **early but functional** — a working prototype, not a facade. Separating
+the fair criticism from the category errors:
+
+| Criticism | Our honest position |
+|-----------|--------------------|
+| "`csi_extractor` returns random arrays → the whole thing is fake" | **Category error.** Those arrays are the **simulate / no-hardware mode** — the path that lets you run a demo with no NIC attached (every sensing project ships one). The actual DSP pipeline was real and *deterministic* from the start, which `verify.py` proves bit-for-bit (§4 Step 1). A reproducible hash is impossible from random data. |
+| "Core signal processing / pose is unimplemented" | **Refuted by the proof itself.** `verify.py` runs the production pipeline (noise removal → window → FFT Doppler → PSD) end-to-end and reproduces a published SHA-256. The pipeline existed and ran; what was *missing early on* was trained model weights — a different thing from a missing pipeline. |
+| "100% presence accuracy" was unsupported | **Fair — formally retracted.** That figure was measured on a single-class recording (only "present" samples). It's replaced everywhere by an honest **82.3% held-out temporal-triplet** accuracy. See the in-place retraction in `README.md` / `docs/user-guide.md`. |
+| Some headline metrics (94.2% pose, 96.5% fall) lacked published evaluation early on | **Fair at the time.** Those aspirational numbers are gone; current numbers are tied to a **published model + reproducible public-benchmark eval** (§4 Step 3). |
+| Docs read like AI ad copy | **Partly fair.** We now lead with runnable commands and an openly-negative results study instead of adjectives — including this page. |
+
+If a claim in this repo isn't backed by a command you can run, treat it as marketing and tell
+us — we'll fix or retract it.
+
+---
+
+## 3. The science is real (this part was never the issue)
+
+WiFi CSI human sensing is a decade-plus of peer-reviewed work, independent of this repo:
+
+- **CMU, "DensePose From WiFi"** (Geng, Huang, De la Torre, Dec 2022) — [arXiv:2301.00250](https://arxiv.org/abs/2301.00250).
+- **MIT CSAIL RF-Pose / RF-Pose3D** (Zhao et al.) — through-wall skeletal pose from radio.
+- **IEEE 802.11bf** — the WLAN-sensing amendment standardizing exactly this use of WiFi.
+- **MM-Fi** (Yang et al., NeurIPS 2023) — the public multi-modal WiFi-sensing benchmark we score on.
+
+The legitimate question was never "is WiFi sensing real?" — it's "does *this implementation*
+actually do it?" The rest of this page answers that.
+
+---
+
+## 4. Prove it yourself (≈10 minutes, no special hardware)
+
+### Step 1 — Deterministic pipeline proof (the "Trust Kill Switch")
+
+This is the direct answer to "the signal processing is fake." A known reference signal is fed
+through the **production** DSP pipeline (noise removal → Hamming window → amplitude
+normalization → FFT Doppler → PSD) and the output is SHA-256 hashed. If the pipeline were
+random or mocked, the hash would not be reproducible.
+
+```bash
+python archive/v1/data/proof/verify.py
+# Expect:  VERDICT: PASS
+# Pipeline hash: f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a
+```
+
+The published expected hash is committed at `archive/v1/data/proof/expected_features.sha256`.
+Run it on your machine — it reproduces **bit-for-bit across platforms** (verified identical on
+Windows, two independent Linux hosts, and the GitHub Azure CI runner). For the one feature that
+*isn't* bit-stable — the peak-normalized Doppler spectrum, whose argmax flips under
+cross-microarchitecture FFT reordering — the proof excludes it from the hash and additionally
+checks every other feature against a committed reference vector within a strict relative tolerance
+(`expected_features_reference.npz`), so a genuine regression still fails while CPU-level float
+noise does not. Five features (amplitude mean/variance, phase difference, correlation matrix, and
+the FFT-based PSD) carry the deterministic proof.
+
+**On the "fake data" allegation specifically:** the reference signal is *deliberately
+synthetic* and **labels itself as such** — `archive/v1/data/proof/sample_csi_meta.json` says:
+
+```json
+{ "is_synthetic": true, "is_real_capture": false, "numpy_seed": 42, ... }
+```
+
+and `generate_reference_signal.py` states in its header: *"It is NOT a real WiFi capture."*
+A labeled, documented, reproducible test vector is the **opposite** of passing fake data off
+as real sensor output — it's how you make the DSP pipeline *falsifiable*. Conflating the two
+was the central error in the "fake CSI" audit.
+
+### Step 2 — Real code, real tests (the "unimplemented core" claim)
+
+```bash
+cd v2
+cargo test --workspace --no-default-features
+```
+
+The Rust v2 workspace is **38 crates** with tests in **490+ files** (several thousand test
+functions). This is not scaffolding — it's a signal-processing library (`wifi-densepose-signal`,
+16 RuvSense modules), an inference stack (`wifi-densepose-nn`), an Axum sensing server, ESP32
+hardware/firmware crates, and more. The test run *is* the proof — don't take the count on
+faith, run it.
+
+### Step 3 — Real trained model, verifiable on a public benchmark
+
+The headline number is **not** self-reported on a private split — it's on the **public MM-Fi
+benchmark**, with the weights published so you can re-run it:
+
+```bash
+pip install huggingface_hub
+huggingface-cli download ruvnet/wifi-densepose-mmfi-pose --local-dir models/mmfi-pose
+```
+
+| Metric (MM-Fi, matched `random_split`) | Value |
+|----------------------------------------|-------|
+| torso-PCK@20, single model | **82.69%** |
+| torso-PCK@20, 3-model ensemble + TTA | **83.59%** |
+| 75K-param micro (edge) variant | 74.30% |
+| Prior published SOTA — MultiFormer (2025) | 72.25% |
+| Prior — CSI2Pose | 68.41% |

+
+### Step 4 — Real CSI from real hardware
+
+A $9 ESP32-S3 produces genuine 802.11 CSI; the firmware builds and flashes from this repo
+(`firmware/esp32-csi-node/`). The data path is ESP-IDF CSI callbacks (or nexmon_csi `.pcap` on a
+Raspberry Pi via the [rvCSI](https://github.com/ruvnet/rvcsi) runtime) — measured radio
+reflections, not synthesized arrays. Build/flash/provision steps are in
+[`docs/user-guide.md`](user-guide.md) and `CLAUDE.local.md`.
+
+---
+
+## 5. Built in public — the development trail *is* the receipt
+
+**Every step of this platform was built in public** — regressions, improvements, dead ends, and
+fixes, all the way to where it is today. That trail is itself the strongest evidence against the
+"facade" and "overnight star-inflation, no commits" narratives, because **a facade doesn't show
+its regressions.** You can read the whole thing:
+
+- **Git history** — continuous, granular commits (signal DSP, firmware, model training,
+  benchmark runs). Not a README drop followed by silence.
+- **96 ADRs** ([`docs/adr/`](adr/README.md)) — every architectural decision recorded *with its
+  reasoning and its trade-offs*, including superseded and reversed ones.
+- **CHANGELOG** — additions, fixes, and reversals dated in place (e.g. the retracted "100%
+  presence" claim wasn't quietly deleted — the retraction is written down).
+- **Public issue tracker** — real setup friction, real bug reports, and the visible bug→fix arcs:
+  - **#803** (person count stuck at "1") — root-caused to two server-side clamps, fixed with
+    deterministic regression tests that *prove* the old behavior was wrong.
+  - **#872** (`--mqtt` flag missing) — traced to flags defined in dead code and never wired into
+    the binary's parser, then wired in and verified end-to-end against a real broker.
+
+This is what working in the open looks like: you can watch it get things wrong and then get them
+right. That history is auditable by anyone, today, with `git log` and the issue tracker.
+
+A facade hides its failures. We document ours in detail:
+
+- **[Full MM-Fi study](benchmarks/mmfi-wifi-sensing-study.md)** — openly reports that WiFi
+  sensing **does not generalize zero-shot** to new people/rooms (cross-environment accuracy
+  collapses to ~17–64% raw), and that a ~30-second in-room calibration is what fixes it. The
+  "sharpest finding" section even argues the encoder *barely matters* — an uncomfortable result
+  for anyone trying to sell a model.
+- **[Efficiency frontier](benchmarks/wifi-pose-efficiency-frontier.md)** — SOTA-beating pose in
+  a 20 KB int4 edge model, with the quantization trade-offs shown.
+- **Retractions** — the "100% presence" figure was withdrawn in-place rather than quietly
+  edited away.
+- **[ADR-147 benchmark proof](adr/ADR-147-benchmark-proof.md)** and
+  **[WITNESS-LOG-028](WITNESS-LOG-028.md)** — how the numbers are produced and a 33-row
+  per-claim attestation matrix.
+
+---
+
+## 6. Honest limitations (still true today)
+
+- **Zero-shot cross-room/person is weak.** Plan on ~30 s of in-room calibration per deployment.
+- **Single-node spatial resolution is limited.** Use 2+ ESP32 nodes (or add a Cognitum Seed)
+  for multi-person / localization.
+- **Multi-person counting is hard.** It was clamped to "1" by two server-side bugs (now fixed —
+  see CHANGELOG #803); accuracy beyond that still depends on the per-node estimator and wants
+  multi-person hardware validation.
+- **Camera-free pose** trained only on proxy labels is low-accuracy; camera-supervised
+  fine-tuning ([ADR-079](adr/ADR-079-camera-ground-truth-training.md)) is the path to good pose.
+- **Beta software.** APIs and firmware change.

+# RuView System Review — Capability Audit (Beyond-SOTA Series, Doc 00)
+
+**Date:** 2026-06-09
+**Scope:** The RuView product surface (ADR-031) and the 38-crate Rust workspace under `v2/crates/` that implements it, plus the ADR corpus (`docs/adr/`, 150 numbered ADRs) and the prior research corpus (`docs/research/sota-2026-05-22/`).
+**Method:** Direct reads of `lib.rs`/`mod.rs` and key ADRs; static test counts via `grep -r '#[test]'` / `#[tokio::test]` per crate (counts are *static occurrences in source*, not CI pass counts). No metrics in this document are estimated — everything cited was read or measured in the working tree.
+
+---
+
+## 1. Executive Summary — What RuView IS Today
+
+RuView is **not a crate**. Per ADR-136 §2.1 (`docs/adr/ADR-136-ruview-streaming-engine-frame-contracts.md`), RuView is the sensing-first *product surface and brand* (ADR-031, status: Proposed) layered on the existing `wifi-densepose-*` / `homecore*` / `cog-*` workspace. ADR-136 explicitly **rejects** a `ruview_*` crate rename and pins a normative ten-role mapping (ingest / signal / fusion / world / models / privacy / store / api / eval / observe) onto the existing crates.
+
+What concretely exists:
+
+1. **A deep, heavily-tested signal-processing layer.** `wifi-densepose-signal` contains 473 static `#[test]` occurrences, including a 22-file `ruvsense/` bounded context (`v2/crates/wifi-densepose-signal/src/ruvsense/`) implementing the ADR-029 six-stage multistatic pipeline plus ADR-030/032a/134/135/137/138/142/143 extensions (~14,000 lines, 330 in-module tests measured by per-file grep).
+2. **A trust-traceable composition root.** `wifi-densepose-engine` (`src/lib.rs`, 752 lines, 11 tests) wires fusion quality (ADR-137), array coordination (ADR-138), evolution change-points (ADR-142), RF-SLAM anchors (ADR-143), the WorldGraph (ADR-139), and the BFLD privacy control plane (ADR-141) into one `StreamingEngine::process_cycle` (`lib.rs:285`) that emits a `TrustedOutput` (`lib.rs:80`) carrying evidence + model version + calibration version + privacy decision + a BLAKE3 witness (`lib.rs:437`).
+3. **A privacy layer with structural invariants.** `wifi-densepose-bfld` (20 modules, 369 tests) implements ADR-118–123/141: raw BFI never exits the node (I1), identity embeddings are RAM-only (I2), cross-site identity correlation is cryptographically impossible (I3) — stated at `wifi-densepose-bfld/src/lib.rs:7-11`.
+4. **A Home-Assistant-class world/state layer.** `homecore` + 9 sibling crates (state machine, event bus, plugins, automation, REST/WS API, recorder, HAP bridge, assist) — explicitly a "P1 scaffold" per `homecore/src/lib.rs:7` with deferred items listed at `lib.rs:24-31`.
+5. **A drone-swarm extension.** `ruview-swarm` (17 modules, ~9,000 lines in subdirectories, 115 + 19 async tests), ADR-148 self-reports ~98% complete with the remaining 15% of M3 gated on real ESP32-S3 hardware (`ADR-148:940-953`).
+6. **A large prior research corpus.** The 2026-05-22 autonomous SOTA loop: 41 ticks, 19 research threads (R1–R20), 22 numpy reference implementations, 7 ADRs, and a 6-tier production roadmap (`docs/research/sota-2026-05-22/00-summary.md`, `PRODUCTION-ROADMAP.md`).
+
+The critical caveat, stated by the project itself: the ADR-136–146 series is *"a skeleton and nervous system, not a shipping product… Most of the series is not yet wired into the live 20 Hz pipeline"* (ADR-136 §8). The engine crate's own docs confirm what is absent: *"the live 20 Hz I/O loop (sensing-server), UWB hardware (ADR-144), and model training (ADR-146)"* (`wifi-densepose-engine/src/lib.rs:27-29`).
+
+---
+
+## 2. Capability Matrix — Pipeline Role → Crates → Maturity
+
+Role mapping is normative per ADR-136 §2.1; maturity is this review's judgment from code + ADR status. Test counts: static `#[test]` + `#[tokio::test]` greps (2026-06-09).
+
+| Role | Crate(s) | Key modules | Tests (sync+async) | Maturity | Evidence |
+|---|---|---|---|---|---|
+| **ingest** | `wifi-densepose-sensing-server`, `wifi-densepose-hardware`, `wifi-densepose-wifiscan` | `csi.rs`, `multistatic_bridge.rs`, `tracker_bridge.rs`, ESP32 TDM | 557+14, 137, 150 | **Production** (hardware-validated per ADR-028/039) | `sensing-server/src/` has 30+ modules incl. MQTT, Matter, RVF pipeline |
+| **signal** | `wifi-densepose-signal` (incl. `ruvsense/`) | 6-stage pipeline (`ruvsense/mod.rs:9-23`), `cir.rs`, `calibration.rs`, `hampel.rs`, `fresnel.rs`, `phase_sanitizer.rs` | 473 | **Production** (unit level); live multistatic wiring **beta** | §3 below; ADR-014 Accepted, ADR-029 Proposed |
+| **fusion** | `ruvsense/multistatic.rs`, `ruvsense/fusion_quality.rs`, `wifi-densepose-ruvector/src/viewpoint/` | `MultistaticFuser`, `QualityScore`, `CrossViewpointAttention`, GDI/Cramér-Rao (`viewpoint/geometry.rs`) | 20 (multistatic.rs), 3 (fusion_quality.rs), 136 (ruvector crate) | **Beta** — tested building blocks, composed only in `wifi-densepose-engine` tests | `viewpoint/mod.rs:1-30`; engine `lib.rs:317-319` |
+| **world** | `homecore`, `wifi-densepose-worldgraph`, `wifi-densepose-geo`, `wifi-densepose-worldmodel` | `StateMachine`, `EventBus`, `WorldGraph` (rooms/sensors/person-tracks/semantic states), ENU geo registration | 9+11, 7, 16+1, 12+1 | **Beta** — homecore is explicit "P1 scaffold"; persistence/service dispatch deferred to P2 | `homecore/src/lib.rs:7, 24-31`; ADR-127 Proposed |
+| **models** | `cog-pose-estimation`, `cog-person-count`, `wifi-densepose-nn`, `wifi-densepose-train`, `wifi-densepose-occworld-candle` | ONNX/Candle inference, training pipeline, OccWorld bridge | 7, 15, 30+1, 312, 12 | **Experimental** — no trained RF foundation encoder exists; ADR-147 benchmarked OccWorld with **random weights** | `ADR-147-benchmark-proof.md` ("random weights — pre-domain-fine-tuning baseline"); ADR-146/150 Proposed |
+| **privacy** | `wifi-densepose-bfld` | `privacy_gate.rs`, `privacy_mode.rs` (mode registry + hash-chained attestation), `identity_risk.rs`, `signature_hasher.rs`, `embedding_ring.rs` | 369 | **Beta** — strongest-tested layer, but lib header still says "Status: P1 in progress" (`lib.rs:12`, stale vs 20 implemented modules) | ADR-118–123, 141 all Proposed |
+| **store** | `homecore-recorder` | trajectory/event recording | 8+12 | **Experimental** | ADR-136 §2.1 |
+| **api** | `homecore-api`, `homecore-server`, `cog-ha-matter`, `homecore-hap` | REST/WS, HA discovery, Matter, HomeKit | 7+11, 0, 63+1, 15+2 | **Experimental→Beta** (`homecore-server` has zero tests) | ADR-130/125/115 Proposed |
+| **eval** | `wifi-densepose-train/src/ablation.rs`, `ruview-swarm/src/evals/` | ablation harness (ADR-145), swarm eval suite (ADR-149) | included in 312 / 115 | **Experimental** — ADR-145 self-labels "skeleton/scaffolding, mostly not yet on the live 20 Hz path" | `ablation.rs` exists; ADR-149 (swarm benchmarking) Accepted |
+| **observe** | `homecore-automation`, `homecore-assist` | automation engine, assistant/Ruflo bridge | 20+14, 3+20 | **Experimental** | ADR-129/133 Proposed |
+| **(integration root)** | `wifi-densepose-engine` | `StreamingEngine`, `TrustedOutput`, privacy demotion, witness | 11 | **Beta** — the only crate that proves cross-role composition; not on a live I/O path | `engine/src/lib.rs:1-29, 457-751` |
+| **(swarm)** | `ruview-swarm` | Raft/gossip topology, RRT-APF planning, Candle PPO MARL, CSI sensing payload, failsafe, Ruflo | 115+19 | **Experimental/simulation** — M3 needs real ESP32-S3 hardware | ADR-148:940-953 ("Overall ~98%", M3 85%) |
+| **(adjacent)** | `nvsim`, `nvsim-server`, `ruv-neural`, `wifi-densepose-wasm-edge`, `wifi-densepose-mat`, `wifi-densepose-vitals` | NV-diamond sim, neural lib, WASM edge, MAT disaster tool, vitals | 50, 0, 364, 643, 165+9, 52 | Mixed — `mat`/`vitals`/`wasm-edge` mature unit-wise | crate listing |
+
+**Workspace totals (measured):** 3,890 `#[test]` + 121 `#[tokio::test]` static occurrences across `v2/crates/`. (CLAUDE.md's "1,031+ tests" figure refers to an earlier `cargo test --workspace` run count; this review did not execute the suite.)
+
+External vendored runtimes also present: `vendor/rvcsi` (ADR-095/096 edge RF runtime, own repo), `vendor/ruvector`, `vendor/midstream`, `vendor/sublinear-time-solver`.
+
+---
+
+## 3. Signal-Processing Capability Inventory — `ruvsense/`
+
+Location: `v2/crates/wifi-densepose-signal/src/ruvsense/`. CLAUDE.md says "16 modules"; the directory now contains **22 `.rs` files** (21 modules + `mod.rs`) — the table below is the ground truth. Lines/tests measured per file (2026-06-09).
+
+| Module | Lines | Tests | ADR | What it does |
+|---|---:|---:|---|---|
+| `mod.rs` | 510 | 14 | 029 | Pipeline shell, COCO-17 keypoint constants, `RuvSensePipeline` (concrete fields + `tick()`), re-exports |
+| `multiband.rs` | 442 | 14 | 029 | Channel-hopping CSI → wideband virtual snapshot per node (`MultiBandCsiFrame`) |
+| `phase_align.rs` | 460 | 13 | 029 | LO phase-offset estimation via circular mean + `ruvector-solver::NeumannSolver` |
+| `multistatic.rs` | 957 | 20 | 029 | Attention-weighted N-node fusion → `FusedSensingFrame`; timestamp-spread guards |
+| `coherence.rs` | 474 | 19 | 029 | Per-subcarrier z-score coherence vs rolling template; `DriftProfile` |
+| `coherence_gate.rs` | 380 | 17 | 029 | Accept / PredictOnly / Reject / Recalibrate gate decisions |
+| `pose_tracker.rs` | 1,577 | 38 | 029/026/082 | 17-keypoint Kalman tracker, lifecycle state machine, AETHER re-ID embeddings, skeleton constraints, temporal keypoint attention |

+| `evolution.rs` | 406 | 7 | 142 | Cross-link change-point detection, Bayesian `TemporalVoxelMap` (privacy-gated) |
+| `rf_slam.rs` | 301 | 6 | 143 | Persistent reflector discovery → static anchor learning (Wall/Furniture/Mobile classes) |
+
+Subtotal: ~14,400 lines, 310 tests inside `ruvsense/` alone. The non-ruvsense signal layer adds Hampel filtering, CSI-ratio, phase sanitisation, Fresnel modeling, BVP, spectrograms, subcarrier selection, and hardware normalisation (`signal/src/*.rs`).
+
+**Cross-viewpoint fusion** (`wifi-densepose-ruvector/src/viewpoint/`, 5 files): scaled dot-product attention with geometric bias (`attention.rs`), Geometric Diversity Index + Cramér-Rao bounds (`geometry.rs`), phase-phasor coherence with hysteresis + clock-quality gate (`coherence.rs`), and the `MultistaticArray` aggregate root (`fusion.rs`). 136 tests crate-wide.
+
+---
+
+## 4. The Trust Chain — What Actually Composes Today
+
+`wifi-densepose-engine/src/lib.rs` is the proof-of-composition. One `process_cycle` (`lib.rs:285-368`):
+
+1. ADR-138 array coordination (only if every node's geometry is registered, `lib.rs:372-389`)
+2. ADR-137 `fuse_scored_calibrated` with **per-node calibration epochs** — mismatching `CalibrationId`s raise a contradiction (`lib.rs:304-319`)
+3. ADR-142 change-point → WorldGraph `Event` node (`lib.rs:393-430`)
+4. ADR-141 monotonic privacy demotion on any contradiction (`demote_one`, `lib.rs:452-455`)
+5. ADR-139/140 `SemanticState` with mandatory provenance (evidence ‖ model ‖ calibration ‖ privacy decision) (`lib.rs:336-352`)
+6. BLAKE3 witness over the trust decision (`witness_of`, `lib.rs:437-448`)
+
+The 11 engine tests verify exactly the right invariants: full provenance flow (`cycle_carries_full_provenance`, `lib.rs:487`), contradiction→demotion (`lib.rs:517`), determinism (`lib.rs:535`), calibration-mismatch→Restricted+stable-witness (`lib.rs:648`), privacy-mode attestation chain (`lib.rs:741`), and persist→reload round-trip with **no raw RF in the snapshot** (`live_frame_to_reload_same_contents`, `lib.rs:696-736`).
+
+This is genuinely strong design. But all inputs are synthetic `MultiBandCsiFrame`s constructed in the test module; no ingest crate calls `StreamingEngine` yet.
+
+---
+
+## 5. Strengths
+
+1. **Deterministic witness chain, end to end in design.** ADR-028 proof (`archive/v1/data/proof/verify.py` + SHA-256), ADR-119 BLAKE3 frame witnesses (`bfld/src/signature_hasher.rs`), ADR-136 `CanonicalFrame`/`ComplexSample` LE contracts, and the engine's per-cycle trust witness form a coherent auditability story few sensing systems attempt.
+2. **Privacy as a control plane, not a feature.** BFLD's three structural invariants (`bfld/src/lib.rs:7-11`), hash-rotation (ADR-120), identity-risk scoring (ADR-121), mode registry with hash-chained attestations, and *monotonic* demotion wired to fusion contradictions (engine `lib.rs:327-328`) — uncertainty automatically reduces information release.
+3. **Multistatic fusion with physics-grounded quality.** Attention fusion + GDI + Cramér-Rao bounds + clock-quality gating means geometry and synchronisation deficits are first-class, measurable contradiction sources rather than silent failure modes.
+4. **Test density at the unit level.** 3,890 static test functions; the signal core (473), BFLD (369), and sensing-server (571) are the deepest. ruvsense files average ~14 tests/module.
+5. **Honest self-assessment culture.** ADR-136 §8's "skeleton, not a shipping product" framing, ADR-147's explicit "random weights" disclosure, and homecore's in-source TODO-P2 ledger (`homecore/src/lib.rs:24-31`) make the gap analysis below mostly a matter of reading what the project already admits.
+6. **A real prior research base with negative results.** The sota-2026-05-22 loop catalogued negatives by resolution path (missing-tool / architecture-error / physics-floor) and produced a ship-recipe (N=5 chest-centric placement, 100% coverage for 1–4 occupants) consolidated into ADR-113.
+7. **Hardware path exists and was audited.** ADR-028 (Accepted) and ADR-039 (Accepted, hardware-validated) anchor the ESP32-S3/C6 ingest tier; firmware release process includes real-CSI verification on COM ports.
+
+---
+
+## 6. Honest Gap Analysis — ADR vs Implemented vs Integrated
+
+| Capability | ADR status | Code status | Integrated on live path? |
+|---|---|---|---|
+| Six-stage ruvsense pipeline | ADR-029 **Proposed** | Implemented + tested (310 tests) | Partially — sensing-server has `multistatic_bridge.rs`/`tracker_bridge.rs`, but `RuvSensePipeline` still holds concrete fields with `tick()` only (`mod.rs`); no uniform `Stage<I,O>` chain runs live |
+| Frame contracts (`ComplexSample`, provenance fields, `Stage` traits) | ADR-136 Proposed | Built + 9 acceptance tests (per ADR-136 §8, commit `11f89727f`) | **No** — AC6 600-frame replay witness key and AC7 cross-arch CI matrix not done; provenance fields not populated by live calibration/model stages |
+| Fusion quality / contradictions | ADR-137 Proposed | `fusion_quality.rs` (188 lines, 3 tests) + engine wiring | Engine-tests only |
+| WorldGraph digital twin | ADR-139 Proposed | `wifi-densepose-worldgraph` (4 files, 7 tests) | Engine-tests only; no recorder-backed persistence loop |
+| Privacy control plane | ADR-141 Proposed | `privacy_mode.rs` registry + attestation chain, tested | Engine-tests only; MQTT/HA exposure exists in BFLD but the *engine→BFLD sink* live path is unwired |
+| UWB range fusion | ADR-144 Proposed | **No hardware, no crate** — acknowledged absent (`engine/src/lib.rs:28`) | No |
+| Ablation/leakage eval harness | ADR-145 Proposed | `wifi-densepose-train/src/ablation.rs` exists | Self-labelled "skeleton/scaffolding" (ADR-145 §status) |
+| RF encoder multi-task heads | ADR-146 Proposed | Not trained; `model_id`/`model_version` registry unowned | No — engine stamps `rfenc-v1` as a placeholder string (`lib.rs:338`) |
+| RF foundation encoder | ADR-150 **Proposed** | ADR only | No |
+| World-model forecasting (OccWorld) | ADR-147 (benchmark doc) | Runs on RTX 5080, 72.39M params — **random weights**, no domain checkpoint | No |
+| HomeCore HA port | ADR-125–133 all Proposed | P1 scaffold + siblings; `homecore-server` has **0 tests**; persistence, service mpsc dispatch, device registry, witness integration all deferred (`homecore/src/lib.rs:24-31`) | Partially (API surfaces exist) |
+| BFLD capture path (Nexmon/ESP32 BFI) | ADR-123 Proposed | rvCSI vendored runtime exists for nexmon `.pcap`; BFI-specific capture unverified in this review | Unclear |
+| Drone swarm | ADR-148 In Progress | 17 modules, sim + Candle PPO complete per milestones | **Simulation only** — M3's 15% requires physical ESP32-S3 CSI capture (ADR-148:946) |
+| Federation / DP-SGD / PQC | ADR-105–109 Proposed | `ruview-fed` crate **does not exist** (roadmap Tier 2 item) | No |
+| Antenna-placement CLI (`plan-antennas`) | ADR-113 Proposed; Roadmap Tier 1.1 HIGH | numpy references only; not found as a Rust CLI subcommand | No |
+
+**Pattern:** the unit layer is real and deep; the *integration* layer is one crate (`wifi-densepose-engine`) exercised solely by its own synthetic tests; the *model* layer (anything learned: RF encoder, pose model fine-tuned on CSI, OccWorld domain weights) is the emptiest tier. Nearly every ADR ≥118 carries status **Proposed** even where substantial tested code exists — ADR status hygiene lags implementation in both directions (BFLD code outruns its "P1 in progress" header; ADR-148's "98%" outruns its hardware evidence).
+
+---
+
+## 7. Risk Register
+
+| # | Risk | Likelihood | Impact | Evidence / Notes |
+|---|---|---|---|---|
+| R1 | **Integration gap**: trust chain proven only against synthetic in-test frames; live 20 Hz ingest→engine→BFLD-sink path unwired, so the headline guarantee (auditable provenance on every emission) is unverified in production conditions | High | Critical | `engine/src/lib.rs:27-29`; ADR-136 §8 |
+| R2 | **No trained model**: every learned component (RF encoder ADR-146/150, OccWorld ADR-147) is random-weight or absent; sensing claims beyond coherence/occupancy heuristics cannot ship | High | Critical | ADR-147 "random weights"; ADR-146/150 Proposed |
+| R3 | **Synthetic-validation bias**: ruvsense/engine/swarm tests and the sota-loop results (e.g., R3 "100% (synthetic)", ADR-113 placement numbers) are simulation-derived; real-room domain gap unquantified | High | High | `00-summary.md:45`; PRODUCTION-ROADMAP 2.3 ("turns synthetic numbers into validated numbers") |
+| R4 | **Witness chain incomplete at frame level**: `CsiFrame.data` is still `serde(skip)` (ADR-136 Gap 2); AC6 replay-witness key and AC7 cross-architecture matrix not landed — deterministic replay is a design, not a property | Medium | High | ADR-136 §1.1, §8 |
+| R5 | **Float nondeterminism in fusion** across thread counts could silently break the witness/replay contract once wired | Medium | High | ADR-136 §3.3 risk table (project's own assessment) |
+| R6 | **Privacy bypass via unwired paths**: BFLD invariants are enforced per-module, but until the engine is the *only* route from ingest to API, a sensing-server endpoint can emit ungated state (sensing-server already has 30+ modules incl. pose/vitals APIs predating the control plane) | Medium | Critical | `sensing-server/src/` module list vs engine isolation |
+| R7 | **Hardware dependence + scale**: multistatic TDMA/channel-hopping timing validated on small ESP32 sets; ADR-148 M3 explicitly blocked on real hardware; clock-quality model in engine uses a hardcoded `ClockQualityScore` (`engine/src/lib.rs:384`) | Medium | High | ADR-148:946; hardcoded 50 µs stdev |
+| R8 | **ADR/doc/status drift**: 150 ADRs with near-universal "Proposed" status, stale in-source status headers (`bfld/src/lib.rs:12`), CLAUDE.md "16 ruvsense modules" vs 22 on disk, duplicate ADR numbers (two ADR-050s, two ADR-147s, two ADR-149s, ADR-052 ×2) — institutional-memory value degrades | High | Medium | `ls docs/adr/`; this review §3 |
+| R9 | **Workspace breadth vs maintenance capacity**: 38 workspace crates + 4 vendored subtrees + Python archive + firmware; several crates have 0 tests (`homecore-server`, `nvsim-server`, `wifi-densepose-wasm`, `homecore-plugin-example`); bus factor appears to be ~1 | High | Medium | crate test-count table §2 |
+| R10 | **Eval debt**: no end-to-end accuracy benchmark on real CSI with ground truth exists in-repo (ADR-145 harness is scaffolding; ADR-079 camera ground truth not exercised here) — "beyond SOTA" claims are currently unfalsifiable | High | High | ADR-145 status note; absence of ground-truth datasets in tree |

+## 1. SOTA reference table per capability axis
+
+### 1.1 Pose estimation (WiFi CSI)
+
+| Method | Year | Metric | Dataset / protocol | Tag |
+|--------|------|--------|--------------------|-----|
+| DensePose From WiFi (Geng, Huang, De la Torre) | 2023 | Dense-pose UV regions from CSI, "comparable to image-based approaches" (same-layout); commonly cited AP≈43.5 / AP@50≈87.2 | 3×3 antenna, single-layout lab | exact AP numbers **[K]**; paper existence **[V]** (arXiv 2301.00250) |
+| MetaFi++ (Zhou et al.) | 2023 | PCK@50 = **97.30%** same-domain real-world (MetaFi: 95.23%); drops to **81.7–86.5%** under stricter protocols | Own capture; protocol-sensitive | **[V]** |
+| Person-in-WiFi 3D (CVPR 2024) | 2024 | End-to-end multi-person 3D; 20.4 M params, **54 FPS**; MPJPE ≈ 90–100 mm on own dataset | Own multi-person dataset | FPS/params **[V]**; MPJPE range **[K]** |
+| GraphPose-Fi (arXiv 2511.19105) | 2025 | SOTA on MM-Fi random split: **MPJPE 160.6 mm**, best PCK at all thresholds | MM-Fi, random split (S1) | **[V]** |
+| CSDS (Electronics 14(4):756) | 2025 | Wi-Pose: PCK@5 = **0.6407**, PCK@50 = **0.8824** | Wi-Pose | **[V]** |
+| PerceptAlign (arXiv 2601.12252) | 2026 | Cross-layout 3D: MPJPE **222.4 mm** (Scene 4) / **317.1 mm** (Scene 5), >54% better than prior cross-layout SOTA; in easier settings MPJPE 181.5 mm, PCK@20/50 = 44.2/79.5 | Cross-layout protocol | **[V]** |
+| WiFlow (arXiv 2602.08661) | 2026 | Lightweight continuous HPE, spatio-temporal decoupling | — | **[V]** (existence; numbers not extracted) |
+| **RuView / AetherArena** | 2026 | **81.63% torso-PCK@20 in-domain (random split), beating MultiFormer's 72.25%** on metric/protocol-matched MM-Fi; **leakage-free cross-subject collapses to ~11.6% torso-PCK zero-shot**; official-split harness baseline ~63–65% PCK@20; **11 KB LoRA few-shot calibration → 72.5%** | MM-Fi (issue #876, ADR-150 §3) | **[I]** |
+
+**The honest reading of the pose axis**: same-domain WiFi pose is "solved-looking" (PCK@50 in the 90s) and meaningless for deployment. The 2025–2026 literature has shifted to cross-layout/cross-subject protocols, where numbers collapse (PerceptAlign PCK@20 = 44.2 cross-layout **[V]**; RuView cross-subject zero-shot 11.6% **[I]**). ADR-150's measured finding — that the cross-subject gap is **subject-distribution shift, not an algorithmic gap**, and that **few-shot in-room calibration (5–200 frames) closes it** — is ahead of where the published literature is: no published WiFi-pose paper we found ships a per-room ~11 KB adapter calibration mechanism. **[I]**

+### 1.2 Presence / person count
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| Large-scale commodity router deployment (>10 M routers) | 2025 | **92.6% motion-detection accuracy** across diverse homes | **[V]** (ISAC survey, arXiv 2510.14358) |
+| LeakyBeam (NDSS 2025) | 2025 | Occupancy through walls at 20 m from **plaintext BFI alone**: TPR 82.7%, TNR 96.7% | **[V]** (also in BFLD survey §4.2) |
+| Time-Selective RNN multi-room presence (arXiv 2304.13107) | 2023 | Device-free multi-room presence from CSI | **[V]** (existence) |

+
+### 1.3 Vital signs (HR / BR)
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| PhaseBeat (ACM Health) | 2020 | HR median error **1.19 bpm**; BR median error **0.25 breaths/min** | **[V]** |
+| MDPI Sensors 24(7):2111 non-contact HR | 2024 | HR accuracy 96.8%, **median error 0.8 bpm** | **[V]** |
+| PulseFi (arXiv 2510.24744) | 2025 | Low-cost ML cardiopulmonary + **apnea** monitoring from CSI | **[V]** (existence; numbers not extracted) |
+| mmWave FMCW vitals (60 GHz class) | 2023–2026 | HR MAE typically 1–3 bpm at 1–3 m, single subject; age-balanced reference dataset published (Sci Data 2026) | dataset **[V]**; MAE range **[K]** |
+| Contactless blood pressure (WiFi-band) | — | **NEGATIVE** — below classical physics floor; recoverable only via quantum magnetometry path | **[I]** (R13/R20 arc, ADR-114) |
+| **RuView** | 2026 | `wifi-densepose-vitals` (ADR-021) extracts HR/BR from ESP32 CSI; chest-centric placement gives **+27 pp coverage** for vitals cogs (synthetic) | **[I]** — **no accuracy-vs-ECG validation number exists in-repo yet; do not claim one** |
+
+**Bar**: published single-subject, line-of-sight, 1–3 m WiFi HR is ~0.8–1.2 bpm median error **[V]**. Nobody credibly publishes multi-person, through-wall, walking-subject HR at that accuracy — that is open territory.
+
+### 1.4 Localization (ToA / CRLB)
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| 802.11mc FTM | shipped | 1–2 m typical accuracy | **[V]** (FTM survey, arXiv 2509.03901) |
+| 802.11az (+ 802.11bk) | released | **sub-1 m**, 160 MHz channels, secured ranging, HE-LTF repetitions | **[V]** |
+| AI single-link decimeter localization | 2025 | **0.63 m average error** single-link, beating Widar2.0 / Dynamic-MUSIC | **[V]** |
+| SpotFi / Chronos / Widar lineage | 2015–2021 | 0.4–1 m with multi-AP CSI AoA/ToF | **[K]** |
+| **RuView** | 2026 | CRLB / Fisher-information machinery in `ruvector/src/viewpoint/geometry.rs`; tomography ISTA voxel grid; **theoretical** limits derived internally: 30–60 cm at 16 nodes/1 m spacing, 8.8 cm information-theoretic dense limit | **[I]** (rf-topological-sensing doc 09 — synthetic derivations, no bench numbers) |
+
+### 1.5 Through-wall
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| RF-Pose / RF-Pose3D (MIT, FMCW 5.4–7.2 GHz) | 2018 | Through-wall skeletal pose, ~specialized radar not commodity WiFi | **[K]** |
+| Commodity 2.4 GHz through-wall imaging (arXiv 1903.03895) | 2019 | Coarse imaging through walls with commodity WiFi | **[V]** (existence) |
+| Radio tomographic imaging (RTI) lineage | 2010–2013 | Through-wall tracking via RSS networks, ~0.5–1 m tracking error | **[V]** (papers) / error figure **[K]** |
+| LeakyBeam (NDSS 2025) | 2025 | Through-wall **occupancy** at 20 m, passive, commodity | **[V]** |
+| **RuView** | 2026 | RF tomography module (`tomography.rs`, ISTA L1 voxel solver) + CIR (ADR-134) exist as code; **PABS structure detection: 1,161× static / 9.36× dynamic intruder lift (synthetic)** | **[I]** |
+
+Notably, the 2025–2026 web literature shows through-wall *pose* (not just presence) on commodity WiFi remains essentially where it was in 2019 — no verified commodity-WiFi through-wall pose benchmark surfaced in our searches. The frontier moved to privacy attacks (BFI) instead.
+
+### 1.6 Identity / re-ID (capability and threat simultaneously)
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| BFId (KIT, ACM CCS 2025) | 2025 | **~99.5% (near-100%) re-ID across 197 subjects** from beamforming feedback alone, ≥5 s of BFI | **[V]** (also BFLD survey §4.1) |
+| Transformer CSI identification | 2025 | **99.82%** on stationary subjects | **[V]** |
+| WhoFi (arXiv 2507.12869) | 2025 | Deep person re-ID via WiFi channel encoding, ~95% rank-1 class results | existence **[V]**; exact number **[K]** |
+| Wi-Gait | 2023 | 92.9% over 10 subjects, robust to walking cofactors | **[V]** |
+| **RuView** | 2026 | AETHER contrastive re-ID embeddings (ADR-024) in pose tracker; **BFLD**: first *defensive* identity-leak detector (identity_risk_score) — the literature attacks, RuView audits | **[I]** |
+
+### 1.7 Adjacent modality: mmWave radar (the accuracy ceiling WiFi is chasing)
+
+| Method | Year | Metric | Tag |
+|--------|------|--------|-----|
+| mmChainPose | 2025 | **27.0 mm MPJPE** / 0.8706 OKS on MARS (mmWave point cloud) | **[V]** |
+| ProbRadarM3F (arXiv 2405.05164) | 2024–25 | SOTA AP across joints, probability-map fusion | **[V]** |
+| Seeed MR60BHA2-class 60 GHz FMCW | shipped | Commodity $15 HR/BR/presence module — already in RuView's hardware table | **[I]** |
+
+mmWave is ~6× better than the best WiFi MPJPE (27 mm vs 160 mm) **[V]**. The strategic implication: WiFi will not beat mmWave on raw geometry; it wins on ubiquity, cost, through-wall propagation, and standardized waveforms (§2). RuView already hedges with the ESP32-C6 + MR60BHA2 fusion node. **[I]**
+
+---
+
+## 2. IEEE 802.11bf — status and implications
+
+**Status (verified)**: IEEE **802.11bf-2025 is ratified and published** (IEEE SA lists the amendment; ratification late 2024 / publication 2025) **[V]**. It amends MAC/PHY of HE (Wi-Fi 6) and EHT (Wi-Fi 7) plus DMG/EDMG (60 GHz) to support WLAN sensing in 1–7.125 GHz and >45 GHz bands **[V]**. The Wi-Fi Alliance has Wi-Fi Sensing as an active certification work area built on 802.11bf (presence/proximity, gestures, vital signs) **[V]**. Market reports claim >47 chipset vendors with 802.11bf-compatible programs as of early 2026 — single weak source, treat as directional **[V, low confidence]**.
+
+**What it implies for RuView**:
+
+1. **Sounding-on-demand becomes standard.** 802.11bf defines a sensing-measurement procedure (sensing initiator/responder, trigger-based sounding, threshold-based reporting). Today RuView relies on Espressif's vendor CSI API and Nexmon firmware patches; post-bf, commodity Wi-Fi 7 silicon will expose scheduled sensing measurements without firmware hacks. The rvCSI normalized `CsiFrame` schema is the right abstraction layer to absorb a future bf adapter (`rvcsi-adapter-*`). **[I]**
+2. **The moat moves up the stack.** When every router can sense, raw CSI access stops being differentiating. Differentiators become: multistatic fusion, coherence gating / anti-hallucination, calibration mechanisms, witness-grade verification, and privacy auditing — exactly RuView's existing bets (ADR-029/135/150/028, BFLD). **[I]**
+3. **Privacy pressure intensifies.** 802.11bf standardizes the capability that BFId/LeakyBeam exploit. BFLD's identity-leak detection and the ADR-105–109 privacy/PQC chain become regulatory assets, not nice-to-haves. **[V]+[I]**
+4. **Threshold-based reporting** in bf (report only when channel changes exceed threshold) is architecturally the same idea as RuView's coherence gate — validation that the gate belongs at the protocol layer. **[K]** (bf reporting detail from training knowledge)
+

+
+## 3. RF foundation model landscape ("GPT for RF")
+
+Verified 2025–2026 attempts, all young, none dominant:
+
+| Model | Approach | Downstream tasks | Tag |
+|-------|----------|------------------|-----|
+| **LWM (Large Wireless Model)** | Pretrained on large-scale CSI → general channel embeddings | LoS/NLoS, beats raw features in low-data regimes | **[V]** |
+| **LatentWave** (arXiv 2606.06373) | JEPA pretraining on wireless spectrograms + CSI | RF classification, 5G NR positioning, beam prediction, LoS/NLoS | **[V]** |
+| **WirelessJEPA** (arXiv 2601.20190) | Multi-antenna spatio-temporal latent prediction | Cross-task transfer | **[V]** |
+| **IQFM** | Contrastive SSL on raw I/Q | Modulation classification, beam prediction, RF fingerprinting, few-shot | **[V]** |
+| **Multimodal Wireless FMs** (arXiv 2511.15162), **WMFM** (arXiv 2512.23897), **SoM** (arXiv 2506.07647) | Vision + RF multimodal for 6G ISAC | Sensing-communication integration | **[V]** |
+| **DeepSig OmniSIG** | Commercial AI-native RF sensing, 500 MHz/GPU spectrum | Signal ID (LTE/5G/Wi-Fi) | **[V]** |
+
+**Critical observation**: every verified RF foundation model targets *communication-side* tasks (beam prediction, LoS/NLoS, modulation, positioning). **None of them is a human-sensing foundation model** — none pretrains for pose/vitals/identity invariances. ADR-150's measured negative result is the sharpest data point in this space: pose-contrastive pretraining across subjects **failed on MM-Fi because the invariance is not in the data** (loss never left the ln(B) floor) **[I]**. The literature has not yet published this failure mode; the field's "GPT for RF sensing" narrative is ahead of its evidence. The defensible foundation-model objective (per ADR-150 §3.5–3.6) is **reduce few-shot calibration cost**, not zero-shot invariance. **[I]**
+
+---
+
+## 4. "Beyond SOTA" for RuView — precise definition
+
+Targets below are **bar definitions**, not claims. RuView numbers in the "current" column are measured [I]; targets must be proven via the AetherArena witness protocol (ADR-149) before being asserted anywhere.
+
+| Capability | Published SOTA (2026) | RuView measured today | RuView beyond-SOTA target | Key obstacle |
+|------------|----------------------|----------------------|---------------------------|--------------|
+| Pose, in-domain (MM-Fi) | GraphPose-Fi 160.6 mm MPJPE; MultiFormer 72.25% torso-PCK@20 **[V]** | **81.63% torso-PCK@20** (already > published) **[I]** | Hold #1 under leakage-free audit + per-joint tables published with witness rows | Protocol fragmentation; reviewers distrust WiFi-pose numbers |
+| Pose, cross-subject zero-shot | ~collapse everywhere; PerceptAlign PCK@20 44.2 cross-layout **[V]** | 11.6% torso zero-shot; 63–65% in-harness official split **[I]** | Stop chasing it (measured dead end); instead **few-shot frontier** below | Subject-distribution shift is in the data, not the model (ADR-150 §3.2) |
+| Pose, deployment calibration | **No published per-room adapter mechanism found** | **11 KB LoRA, 100–200 frames → 72.5%; cross-env K=5 → 60.1%** **[I]** | ≤20 frames → ≥70% PCK@20, adapter ≤11 KB, 30 s on-site; publish as the first calibration-service benchmark | Needs diverse-room capture fleet to validate beyond MM-Fi |
+| Presence/motion (commodity) | 92.6% across 10 M routers **[V]** | Synthetic placement recipe 100% coverage N=5 **[I]** | ≥99% presence with calibrated p95 bounds on $6–15 ESP32 mesh, bench-validated | All placement numbers are synthetic; Tier-2.3 bench validation outstanding |
+| Person count | ~90–97% lab, ≤5 people **[K]** | cog ships uncertainty intervals **[I]** | Exact count 1–6 people ≥95% with honest intervals, multistatic, real bench | Multi-person CSI superposition; no public multi-occupancy benchmark |
+| Vital signs HR | 0.8–1.2 bpm median, single subject, LoS, 1–3 m **[V]** | No in-repo ECG-validated number — **must not be claimed** | ≤1.5 bpm MAE vs ECG ground truth, *multi-person or through-wall*, witness-bundled | R13 physics floor: ~5 dB shortfall at distance; needs chest-centric placement + PABS |
+| Vital signs BP | NEGATIVE at WiFi band (matches internal R13) | nvsim quantum path only **[I]** | First validated quantum-classical fused bedside vitals (ADR-114) | NV-diamond hardware maturity, 2028+ |
+| Localization | 0.63 m single-link AI; sub-1 m 802.11az **[V]** | CRLB machinery, no bench number **[I]** | ≤30 cm multistatic on ESP32 mesh (internal theory says feasible at N=16) | ESP32 clock sync / phase offset (TDM protocol exists, unproven at this accuracy) |
+| Through-wall | Occupancy yes (LeakyBeam); commodity pose: nothing credible **[V]** | tomography + CIR code, PABS 9.36× lift (synthetic) **[I]** | First witnessed commodity-WiFi through-wall *person localization* (not pose) ≤1 m | Wall attenuation eats the R6.1 4.7 dB multi-scatterer budget |
+| Identity / re-ID | ~99.5% @ 197 subjects (attack) **[V]** | AETHER + **BFLD defensive auditing** (no published competitor) **[I]** | Ship the first identity-leak risk score with DP budget hook; keep re-ID opt-in only | Calibrating risk score at 802.11ax 4/2-bit quantization (BFLD open Q2) |
+| Verification | **Nothing comparable published** — no WiFi-sensing paper ships deterministic re-verification | ADR-028 witness bundles, SHA-256 proof, 7/7 self-verify, 1,031+ tests **[I]** | Make witness-grade reproduction the *expected* standard: every public claim = one-command verification | Community adoption, not technology |
+| Foundation encoder | Comms-task FMs only (LWM/JEPA family) **[V]** | Masked-CSI + coherence head planned; pose-contrastive refuted **[I]** | First *sensing* FM whose acceptance metric is calibration-sample reduction (frames-to-72% halved) | SSL must match production CSI pipeline (ADR-149 resampling risk) |
+
+---
+
+## 5. Where RuView already matches/exceeds published work
+
+1. **In-domain MM-Fi pose** — 81.63% torso-PCK@20 vs MultiFormer 72.25%, metric- and protocol-matched (issue #876). **[I]**
+2. **Deployment-calibration mechanism** — the 11 KB LoRA per-room adapter with measured frames-to-accuracy curves (§3.4–3.6 of ADR-150) has no published equivalent; the literature is still arguing about zero-shot generalization that ADR-150 measured to be a data property.
+3. **Deterministic witness verification** — ADR-028's SHA-256 pipeline proof + self-verifying bundles exceeds the reproducibility practice of every WiFi-sensing paper surveyed (none ship deterministic re-verification).
+4. **Multistatic cost point** — $6–15/node ESP32 mesh with TDM sync, channel hopping, placement recipes (ADR-113) vs literature setups using Intel 5300/AX210 laptops or USRPs; ~$30/bed vs $3,000 clinical monitor framing (R16).
+5. **Defensive identity auditing (BFLD)** — the field publishes attacks (BFId, LeakyBeam, WhoFi); RuView is building the only detector/auditor, plus a PQC-hardened federation privacy chain (ADR-105–109) with no published counterpart.
+6. **Anti-hallucination coherence gating** — confidence gated by RF integrity (ADR-135, ADR-150 §2.4); WiFi-pose papers uniformly lack a "the model knows when the channel is bad" signal.
+7. **Negative-result discipline** — physics floors (R13 BP, R6.1 4.7 dB), refuted pose-contrastive pretraining — published SOTA papers do not report these, which inflates the apparent literature bar.
+
+## 6. Where RuView lags
+
+1. **Bench validation** — nearly all multistatic/placement/tomography numbers are synthetic-physics; the 92.6%-on-10M-routers deployment **[V]** is real-world evidence at a scale RuView cannot approach.
+2. **Vital-sign ground truth** — no in-repo ECG/respiration-belt validated HR/BR error; published work has 0.8 bpm median **[V]**. This is the most urgent claim gap.
+3. **Raw geometric accuracy** — mmWave (27 mm MPJPE **[V]**) and even best-WiFi MPJPE (160.6 mm **[V]**) have no RuView MPJPE counterpart published; AetherArena reports PCK only.
+4. **802.11bf-native capture** — RuView is on vendor CSI APIs and Nexmon patches; no bf sensing-procedure adapter exists yet in rvCSI.
+5. **Multi-person pose** — Person-in-WiFi-3D does end-to-end multi-person at 54 FPS **[V]**; RuView's pose path is effectively single-person (multi-person exists only in count/placement work).
+6. **Dataset scale and diversity** — MM-Fi only; ADR-150 §3.3 shows the binding constraint is room/device/protocol diversity, which requires the capture fleet that doesn't exist yet.
+
+## 7. Strategic synthesis
+
+The 2026 bar is bimodal: **lab in-domain numbers are saturated** (PCK@50 > 95%, HR < 1 bpm) and **deployment numbers are collapsed** (cross-layout PCK@20 ≈ 44, zero-shot cross-subject ≈ 11%). 802.11bf-2025 commoditizes raw sensing; foundation models commoditize comms-side embeddings. "Beyond SOTA" for RuView is therefore *not* a leaderboard delta — it is owning the three layers the field hasn't built: **(a)** witnessed, deterministic, leakage-audited evaluation; **(b)** the few-shot calibration service (11 KB adapters) as the deployment answer the zero-shot literature lacks; **(c)** the privacy/integrity layer (BFLD + coherence gate) that 802.11bf-era regulation will demand. Each row in §4's target table is gated on the AetherArena witness protocol — a target becomes a claim only when it ships with a one-command reproduction.

+# RuView Beyond-SOTA Target Architecture
+
+**Series:** ruview-beyond-sota (02)
+**Date:** 2026-06-09
+**Status:** Research design — components marked **PROPOSED** do not exist yet; everything else cites real code.
+**Governing constraint:** ADR-136 §2.1 explicitly rejects renaming/rewriting the workspace. This document designs an **evolution** of the existing 38-crate `v2/` workspace (`v2/Cargo.toml`), not a new system. Every beyond-SOTA layer attaches to the ADR-136 `Stage<I,O>` / `FrameMeta` / `CanonicalFrame` contracts (`docs/adr/ADR-136-ruview-streaming-engine-frame-contracts.md` §2.2–2.5) and preserves the ADR-028 witness chain.
+
+---
+
+## 1. Where the system is today (grounding)
+
+The ADR-136 ten-role pipeline (ingest → signal → fusion → world → models → privacy → store → api → eval → observe) is already mapped 1:1 onto existing crates (ADR-136 §2.1, normative table). The composition root exists: `v2/crates/wifi-densepose-engine/src/lib.rs` wires ADR-135..146 blocks into one `StreamingEngine::process_cycle` that emits a `TrustedOutput` carrying fusion `QualityScore`, privacy class, `SemanticProvenance`, RF-SLAM (`RfSlam` field), and a BLAKE3 `witness: [u8; 32]`.
+
+Key existing substrate this design builds on:
+
+| Substrate | Path | What it gives us |
+|---|---|---|
+| Frame contracts + witness | `v2/crates/wifi-densepose-core/src/types.rs` (`CsiFrame`, `CsiMetadata` + `calibration_id`/`model_id`/`model_version`), ADR-136 `ComplexSample`/`CanonicalFrame` | Deterministic LE bytes, BLAKE3 witness, provenance-append-only boundary rule |
+| Six-stage signal pipeline | `v2/crates/wifi-densepose-signal/src/ruvsense/mod.rs` (+22 modules incl. `cir.rs`, `calibration.rs`, `tomography.rs`, `rf_slam.rs`, `fusion_quality.rs`, `array_coordinator.rs`) | CSI→CIR, baseline calibration, multistatic fusion, coherence gating |
+| Fusion quality + evidence | ADR-137; `ruvsense/multistatic.rs`, `ruvsense/fusion_quality.rs`, `wifi-densepose-ruvector/src/viewpoint/fusion.rs` | `QualityScore` with `EvidenceRef`/`ContradictionFlag`, privacy demotion on contradiction |
+| Digital twin | `v2/crates/wifi-densepose-worldgraph/src/lib.rs` (typed `StableDiGraph`, mandatory `SemanticProvenance`) | Persistent room/sensor/track/belief graph |
+| World model bridge | `v2/crates/wifi-densepose-worldmodel/src/lib.rs` (`OccWorldBridge`, `TrajectoryPrior`, ADR-147) | Occupancy prediction priors into the Kalman tracker |
+| NN + training | `v2/crates/wifi-densepose-train/src/{model.rs,rapid_adapt.rs,ablation.rs,proof.rs,eval.rs,ruview_metrics.rs}`, `wifi-densepose-nn` | Shared backbone + 2 heads, `AdaptationLoss::ContrastiveTTT`, ADR-145 ablation matrix, seeded proof harness |
+| Swarm | `v2/crates/ruview-swarm/src/` (`sensing/{multiview.rs,payload.rs,occworld_bridge.rs}`, `marl/`, `topology.rs`) | Raft/hierarchical-mesh drone coordination with CSI payload (ADR-148) |
+| Edge WASM | `v2/crates/wifi-densepose-wasm-edge/src/lib.rs` (WASM3 on ESP32-S3, `on_frame` host ABI), `wifi-densepose-wasm` | Hot-loadable on-device sensing modules |
+| Quantum-adjacent sim | `v2/crates/nvsim/src/lib.rs` (deterministic NV-magnetometry forward pipeline, SHA-256 witness, WASM-ready) | Honest classical-quantum hybrid substrate (ADR-089) |
+| Semantic record + agents | ADR-140 (`wifi-densepose-sensing-server/src/semantic/`), `homecore-assist` | Provenance-bearing semantic states, Ruflo agent bridge |
+

+
+## 3. The eight pillars
+
+Each pillar: what / why beyond-SOTA / builds-on / contract sketch / feasibility. All trait sketches are **PROPOSED** unless a path is cited.
+
+### P1 — RF Foundation Encoder with multitask uncertainty heads (ADR-146 + ADR-150)
+
+**What.** One shared, self-supervised RF encoder (`wifi-densepose-nn`) with seven typed heads (pose, presence, count, activity, vitals, gait, identity-embedding), each emitting calibrated uncertainty via the ADR-136 `QualityScored` trait, trained with the ADR-150 pose-contrastive objective (same-pose-across-subjects = positive) plus a coherence head that exposes channel instability.
+
+**Why beyond SOTA.** Published WiFi-pose systems (MultiFormer, GraphPose-Fi lineage) report in-domain accuracy and hallucinate under domain shift. ADR-150 documents the real measured frontier: 81.63% torso-PCK@20 in-domain on MM-Fi vs ~11.6% leakage-free cross-subject, and that DANN and bigger capacity both failed (ADR-150 §1). A foundation encoder whose loss stack explicitly separates pose / identity / room / device factors *and* emits an RF-integrity signal per prediction is not in the published literature as a deployed, auditable artifact. Target (not a claim): close the cross-subject gap materially while every head output carries `confidence_bounds()`.
+
+**Builds on.** `v2/crates/wifi-densepose-train/src/model.rs` (`WiFiDensePoseModel`, `kp_head`/`dp_head`); `v2/crates/wifi-densepose-sensing-server/src/embedding.rs` (`ProjectionHead` + LoRA + `info_nce_loss` — the existing seventh head, ADR-146 §1.1); `v2/crates/wifi-densepose-train/src/rapid_adapt.rs` (ContrastiveTTT precedent); ADR-146 §1.4 head fan-out; ADR-150 §2 loss stack.
+
+**Contract sketch** (lands in `wifi-densepose-nn`, per ADR-146 §1.3):
+```rust
+pub trait RfEncoder: Send + Sync {
+    fn encode(&self, window: &CsiWindowTensor) -> Embedding;        // z ∈ R^d_model
+    fn model_id(&self) -> u16;                                       // FrameMeta binding (ADR-136 §2.2)
+}
+pub trait TaskHead<O: QualityScored>: Send + Sync {
+    fn name(&self) -> &'static str;
+    fn forward(&self, z: &Embedding) -> O;                           // value + uncertainty bounds
+}
+pub struct MultiTaskOutput { /* per-head QualityScored outputs + coherence: f32 */ }
+```
+
+**Feasibility: HIGH for the architecture, MEDIUM for the headline result.** The pure-Rust f32 ABI is proven (`embedding.rs`), the head taxonomy is specified (ADR-146), and the ablation harness to measure it exists (`wifi-densepose-train/src/ablation.rs`). The risk is scientific, not engineering: ADR-150's own data shows naive approaches fail; the pose-contrastive objective is plausible but unproven at scale. Mitigation: ADR-150 §3's frozen-decoder three-variant experiment gates promotion.
+
+### P2 — Physics-informed differentiable RF forward model (PROPOSED)
+
+**What.** A differentiable forward model `render(scene, link_geometry) -> predicted CSI/CIR` used three ways: (1) as a regularizer in encoder training (predictions must be consistent with a Born-approximation scattering model), (2) as an analysis-by-synthesis residual at inference (`|observed − rendered|` becomes an ADR-137 `EvidenceRef`), (3) as a synthetic-data generator complementing MM-Fi (ADR-015).
+
+**Why beyond SOTA.** Published WiFi sensing is almost entirely discriminative; physics-informed neural fields exist for vision (NeRF) and acoustics but no deployed RF-human-sensing stack closes the loop *forward model → residual → fusion evidence → privacy decision*. Making physics disagreement a first-class, witnessed contradiction flag is novel system design, not just a model.
+
+**Builds on.** The codebase already contains the seed of the forward model: `v2/crates/wifi-densepose-signal/src/ruvsense/tomography.rs` (`RfTomographer`, `LinkGeometry`, `OccupancyVolume` — a linear shadowing forward model inverted by ISTA), `ruvsense/cir.rs` (sub-DFT sensing matrix Φ, ISTA L1 — ADR-134), ADR-143 §1.3 (bistatic excess-delay geometry, the exact ray equations), and `nvsim` as the in-repo precedent for a *deterministic, witness-hashed forward physics pipeline* (`v2/crates/nvsim/src/{propagation.rs,pipeline.rs,proof.rs}`).
+
+**Contract sketch** (new module `wifi-densepose-signal/src/ruvsense/forward_model.rs`, PROPOSED):
+```rust
+pub trait RfForwardModel: Versioned {
+    /// Predict per-link CSI given a voxel scene + body primitive set.
+    fn render(&self, scene: &OccupancyVolume, links: &[LinkGeometry]) -> Vec<PredictedCsi>;
+    /// Physics residual in [0,1]; 0 = perfectly Maxwell/Born-consistent.
+    fn residual(&self, observed: &CsiFrame, rendered: &PredictedCsi) -> PhysicsResidual; // → EvidenceRef
+}
+```
+
+**Feasibility: MEDIUM, with one honest line drawn.** A full Maxwell FDTD-in-the-loop solver is **infeasible** at 20 Hz on this hardware and is a non-goal (§6). What is feasible: a first-order Born / ray-tracing bistatic model (the ADR-143 spheroid geometry generalized), differentiable through finite differences or a small Candle graph, validated against recorded calibration captures (ADR-135 baselines give per-link empty-room ground truth for free). "Maxwell-consistent" should be read as "consistent with a stated first-order approximation, with the approximation order recorded in the witness metadata."
+
+### P3 — RF-SLAM × WorldGraph × OccWorld closed loop (exists in parts, wiring is the work)
+
+**What.** Close the loop: RF-SLAM discovers reflectors/anchors → WorldGraph persists them as `object_anchor` nodes → OccWorld consumes graph occupancy → `TrajectoryPrior`s feed the Kalman tracker → improved tracks refine SLAM association. The environment model becomes self-acquiring and self-correcting (furniture moved ⇒ `BaselineTopologyChange` ⇒ recalibration trigger, ADR-143 §1.4).
+
+**Why beyond SOTA.** Published RF-SLAM work maps *or* tracks; no published consumer system maintains a persistent, provenance-bearing, privacy-rolled-up environmental digital twin (`PrivacyRollup` in `wifi-densepose-worldgraph/src/graph.rs`) that is simultaneously the SLAM map, the automation substrate, and the audit record. The differentiator is the closed loop with evidence edges (`supports`/`contradicts`).
+
+**Builds on.** All three vertices exist: `v2/crates/wifi-densepose-signal/src/ruvsense/rf_slam.rs` (`RfSlam::observe`, line 176, already a field of `StreamingEngine` — `wifi-densepose-engine/src/lib.rs:116`); `v2/crates/wifi-densepose-worldgraph/src/lib.rs`; `v2/crates/wifi-densepose-worldmodel/src/{bridge.rs,occupancy.rs}` (`worldgraph_to_occupancy`, `OccWorldBridge::predict`). The engine already upserts SLAM output and person tracks into the graph. Missing: prior-injection back into `ruvsense/pose_tracker.rs`, and the topology-change → ADR-135 recalibration edge.
+
+**Contract sketch** (extends existing types):
+```rust
+impl StreamingEngine {
+    /// PROPOSED: inject OccWorld priors into the next tracker cycle.
+    pub fn apply_trajectory_priors(&mut self, priors: &[TrajectoryPrior]) -> Vec<WorldId>;
+}
+// WorldEdge gains (PROPOSED): PredictedBy { model_id: u16 }  — prior provenance edge
+```
+
+**Feasibility: HIGH.** This is mostly integration glue between tested crates. The two real risks are already named by ADR-143: no ground-truth oracle in a live home (mitigated by the v1-fixed / v2-flagged rollout, `#[cfg(feature = "rf-slam-v2")]`), and OccWorld's Python subprocess (ADR-147: 375 ms/inference) being off the deterministic path — priors must be treated as advisory, never witness-bearing (§5).
+
+### P4 — Cross-modal distillation: camera-teacher → RF-student, privacy-preserving deployment (PROPOSED)
+
+**What.** Train-time-only camera supervision: a vision pose teacher labels synchronized CSI (MM-Fi already provides paired modalities, ADR-015), distilling dense pose + uncertainty into the P1 encoder. Deployed systems ship **no camera and no camera-derived identity features**; the ADR-145 privacy-leakage metric (membership-inference score in `wifi-densepose-train/src/ablation.rs`) gates that the student does not retain identity.
+
+**Why beyond SOTA.** Camera-supervised WiFi pose is the original DensePose-WiFi recipe; what is *not* published is distillation with a measured, CI-enforced privacy-leakage budget and a witnessed claim that the deployed artifact is camera-free. The beyond-SOTA move is making "privacy-preserving" a *measured property of the release pipeline*, not a marketing adjective.
+
+**Builds on.** `v2/crates/wifi-densepose-train/src/{trainer.rs,losses.rs,dataset.rs}` (training substrate); ADR-015 paired datasets; ADR-145 `FeatureSet` matrix + privacy-leakage scalar; `v2/crates/wifi-densepose-bfld` (`privacy_gate.rs`, `signature_hasher.rs` — runtime identity controls, ADR-120 invariants I1–I3).
+
+**Contract sketch** (in `wifi-densepose-train`, PROPOSED):
+```rust
+pub struct DistillationLoss { pub teacher: TeacherSource, pub temperature: f32, pub uq_transfer: bool }
+pub enum TeacherSource { CachedPoseLabels(PathBuf), /* never a live camera in the serving graph */ }
+/// Release gate: leakage(student) ≤ budget, asserted by the ADR-145 harness per variant.
+pub struct PrivacyBudget { pub max_mia_score: f32 }
+```
+
+**Feasibility: HIGH.** All ingredients exist; the work is a loss term, a label cache format, and a CI gate. The honest caveat: MIA-based leakage scores are a lower bound on real leakage; the budget is a regression tripwire, not a formal guarantee.
+
+### P5 — Swarm-distributed multistatic sensing with Raft-coordinated apertures (ADR-148, partially built)
+
+**What.** Treat the drone swarm + fixed ESP32 mesh as one *reconfigurable multistatic aperture*: a Raft-elected cluster head plans node positions/channel assignments to maximize geometric diversity (GDI) for the current sensing task; per-node frames flow into the same `MultistaticFuser` path as fixed nodes.
+
+**Why beyond SOTA.** Published multistatic WiFi sensing assumes fixed geometry. Closed-loop aperture optimization — moving the sensors to where the Fisher information is — driven by the GDI/Cramér–Rao machinery that already exists in `v2/crates/wifi-densepose-ruvector/src/viewpoint/geometry.rs` (per CLAUDE.md module table: `GeometricDiversityIndex`, Cramér-Rao bounds) is a genuinely new system class for SAR/MAT scenarios.
+
+**Builds on.** `v2/crates/ruview-swarm/src/sensing/{multiview.rs,payload.rs,occworld_bridge.rs}`, `topology.rs`, `planning.rs`, `marl/` (MAPPO, `candle_ppo.rs`); `ruvsense/multistatic.rs` + `array_coordinator.rs` (ADR-138 clock-quality gating — moving nodes will stress exactly this); `wifi-densepose-mat` (the MAT use case).
+
+**Contract sketch** (in `ruview-swarm`, PROPOSED):
+```rust
+pub trait AperturePlanner: Send + Sync {
+    /// Given current twin + task, propose node placements maximizing expected GDI.
+    fn plan(&self, twin: &WorldGraphSnapshot, task: &SwarmTask) -> Vec<(NodeId, Position3D)>;
+}
+// Output flows through Raft (topology.rs) as a normal SwarmTask; frames return as ArrayNodeInput.
+```
+
+**Feasibility: MEDIUM.** Coordination, MARL, and fusion code exist and are tested; the hard physical problems are honest unknowns: airborne CSI phase stability (rotor vibration), clock sync across mobile nodes (ADR-138 gate will reject a lot initially), and ADR-148 §1.3's own regulatory scoping. Simulation-first via `ruview-swarm/src/evals.rs` + `bench_support.rs`; hardware validation is Phase 3.
+
+### P6 — Continual / test-time adaptation with EWC-style forgetting control (PROPOSED on existing TTT)
+
+**What.** Promote `rapid_adapt.rs` from a per-deployment trick to a managed continual-learning loop: TTT/entropy adaptation produces LoRA deltas on the P1 encoder; an EWC (elastic weight consolidation) penalty — **which does not exist in the workspace today** (no EWC match in `wifi-densepose-train/src/rapid_adapt.rs`) — anchors weights important to previously-validated environments; every adaptation step is versioned as a new `model_version` (u16, ADR-136 §2.2) and must re-pass the ADR-145 acceptance matrix before activation.
+
+**Why beyond SOTA.** TTT papers adapt and hope; nothing published couples adaptation to a *deterministic regression gate with witness hashes*, where an adapted model that regresses tier or leaks identity is automatically rejected and the `model_version` provenance lets any semantic state be traced to the exact adaptation step.
+
+**Builds on.** `v2/crates/wifi-densepose-train/src/rapid_adapt.rs` (`AdaptationLoss::ContrastiveTTT`, entropy-minimization variant — lines 8–16); LoRA adapters in `sensing-server/src/embedding.rs` (rank-4 `lora_1`/`lora_2`); ADR-027 MERIDIAN evaluator (`train/src/eval.rs`); ADR-146 §2 calibration-robustness loss.
+
+**Contract sketch** (in `wifi-densepose-train`, PROPOSED):
+```rust
+pub struct EwcPenalty { pub fisher_diag: Vec<f32>, pub anchor: Vec<f32>, pub lambda: f32 }
+pub struct AdaptationStep {
+    pub parent_model_version: u16, pub new_model_version: u16,
+    pub loss: AdaptationLoss, pub ewc: Option<EwcPenalty>,
+    pub acceptance: RuViewAcceptanceResult,           // must be ≥ parent tier
+    pub witness: [u8; 32],                            // hash of delta + acceptance
+}
+```
+
+**Feasibility: HIGH.** EWC over a small LoRA delta is cheap (Fisher diagonal over the replay corpus); the acceptance gate and proof seeds exist (`proof.rs`, `PROOF_SEED = 42`). Risk: online Fisher estimation from unlabeled home data is noisy — start with adaptation restricted to LoRA parameters only, backbone frozen.
+
+### P7 — On-device WASM edge inference with deterministic replay (extends existing Tier-3)
+
+**What.** Push P1 head subsets (presence, vitals, coarse activity) into hot-loadable WASM modules on ESP32-S3, and onto browsers/workers via `wifi-densepose-wasm`. Every edge module's output is replayable: the same `CanonicalFrame` input bytes through the same module hash produce the same output bytes, verified in CI on x86_64/aarch64/wasm32.
+
+**Why beyond SOTA.** Edge WiFi-sensing exists; *bit-deterministic, witness-hashed edge inference with hot-swap and replay parity against the server pipeline* does not appear in published systems. It turns the edge from a trust hole into a witness-chain extension.
+
+**Builds on.** `v2/crates/wifi-densepose-wasm-edge/src/lib.rs` (WASM3 host ABI: `csi_get_*`, `on_frame` at ~20 Hz, ADR-040 Tier 3); `nvsim` as the proof that a no-std-time, no-OS-entropy, seeded-PRNG crate runs identically on wasm32 (`nvsim/src/lib.rs` doc); ADR-136 AC7 cross-architecture byte-stability test.
+
+**Contract sketch** (PROPOSED additions to the wasm-edge host ABI):
+```rust
+// exports added to module lifecycle:
+//   on_replay_begin(seed: u64)              — pins any module-internal PRNG
+//   witness_digest(buf_ptr: i32) -> i32     — module returns BLAKE3 of its output stream
+pub trait EdgeStage: Stage<CsiFrameView, EdgeEvent> { fn module_hash(&self) -> [u8; 32]; }
+```
+
+**Feasibility: HIGH for presence/vitals heads, LOW for full pose on-ESP32.** WASM3 interpretation on Xtensa caps throughput; full 7-head inference stays on Pi/Hailo/browser. Float determinism across native vs WASM needs care (no fast-math, fixed reduction order — same obligation ADR-136 §3.2 already accepts).
+
+### P8 — NV-magnetometry fusion: an honest classical-quantum hybrid (PROPOSED, simulation-first)
+
+**What.** Add `nvsim`-modeled NV-magnetometer nodes as a *fourth sensing modality class* (after CSI, mmWave/ADR-021, BFLD) in the multistatic fusion: near-range (≤ tens of cm, per the physics review) cardiac/respiratory magnetic signatures fused with CSI/mmWave vitals under the ADR-137 evidence contract. Simulation-first: the modality lands end-to-end against `nvsim` before any hardware exists.
+
+**Why beyond SOTA.** Not range — the Ghost Murmur review (`docs/research/quantum-sensing/16-ghost-murmur-ruview-spec.md`) documents why multi-mile cardiac magnetometry contradicts published physics, and this design adopts that conclusion. The beyond-SOTA element is architectural honesty: a fusion engine that can ingest a quantum-sensor modality with explicit, witnessed physics bounds (`nvsim`'s forward model states its approximations and hashes its output, `nvsim/src/proof.rs`), so that when real NV hardware matures, the integration path and the anti-hype guardrails already exist. No published consumer sensing stack has this.
+
+**Builds on.** `v2/crates/nvsim/src/` (scene→source→attenuation→NV ensemble→digitiser, SHA-256 witness, ADR-089); `nvsim-server`; `wifi-densepose-vitals` (mmWave HR/BR — the modality NV would cross-validate); `ruvsense/multistatic.rs` fusion + ADR-137 `EvidenceRef`.
+
+**Contract sketch** (PROPOSED): a `SensorModality::NvMagnetometer` variant on the existing `wifi-densepose-worldgraph` `SensorModality` enum, plus an `ArrayNodeInput` adapter from `nvsim` frames; vitals agreement/disagreement between NV and mmWave becomes an `EvidenceRef`/`ContradictionFlag` pair.
+
+**Feasibility: HIGH in simulation, SPECULATIVE on hardware.** The sim path is days of glue; COTS NV magnetometers with the required sensitivity at consumer cost do not exist in 2026. This pillar's deliverable is the *contract and the simulated validation*, explicitly labeled as such.
+
+---
+
+## 4. Phased implementation plan
+
+Phases are gated by the Pre-Merge Checklist (CLAUDE.md) and the witness chain (§5). Crate names per the ADR-136 §2.1 normative map — no new `ruview_*` crates except where a crate already exists (`ruview-swarm`).
+
+**Phase 0 — Hardening (close the ADR-136 "integration glue" debt).**
+- `wifi-densepose-signal`: wire the full 600-frame `Stage`-chain replay (ADR-136 AC6) and register `streaming_engine_replay_v1` in `archive/v1/data/proof/expected_features.sha256`.
+- CI: cross-architecture witness matrix x86_64/aarch64 (AC7); add wasm32 lane for `nvsim` + `wifi-densepose-wasm`.
+- `wifi-densepose-engine`: populate `FrameMeta.calibration_id`/`model_id` from the live calibration and model-binding stages (currently defaulted — ADR-136 §8).
+- `homecore-recorder`: define the **replay corpus** format (canonical-bytes frame streams + witness manifest) that P4/P6 training and all ablations consume.
+
+**Phase 1 — Encoder + measurement (P1, P4 groundwork, P6 skeleton).**
+- `wifi-densepose-nn`: `RfEncoder`/`TaskHead` traits, seven-head fan-out, UQ layer (ADR-146); relocate `ProjectionHead` from `sensing-server/src/embedding.rs`.
+- `wifi-densepose-train`: `ContrastiveBatcher`, ADR-150 loss stack, distillation loss + cached-teacher format (P4), `EwcPenalty` + `AdaptationStep` (P6); extend `ablation.rs` `FeatureSet` with per-head and per-pillar variants; pin `expected_ablation_*.sha256`.
+- Run the ADR-150 three-variant frozen-decoder experiment; promotion gate on cross-subject delta.
+
+**Phase 2 — Closed loop + edge (P3, P7).**
+- `wifi-densepose-engine`: `apply_trajectory_priors` (OccWorld → `pose_tracker.rs`); `PredictedBy` provenance edge in `wifi-densepose-worldgraph`; topology-change → ADR-135 recalibration trigger.
+- `wifi-densepose-wasm-edge`: replay ABI (`on_replay_begin`, `witness_digest`), presence/vitals head modules; parity test vs server pipeline on identical canonical bytes.
+- Enable `rf-slam-v2` feature on the 7-day validation dataset (ADR-143 gate).
+
+**Phase 3 — Frontier (P2, P5, P8).**
+- `wifi-densepose-signal/src/ruvsense/forward_model.rs`: Born/ray forward model seeded from `tomography.rs`; `PhysicsResidual` → `EvidenceRef`; synthetic-data generator into `train/src/dataset.rs`.
+- `ruview-swarm`: `AperturePlanner` over GDI (`ruvector/src/viewpoint/geometry.rs`); simulation evals in `evals.rs`; airborne CSI stability study before any hardware claim.
+- `nvsim` ↔ `wifi-densepose-engine`: `SensorModality::NvMagnetometer` adapter, simulated NV+mmWave vitals cross-validation in the ablation matrix.
+
+---
+
+## 5. Determinism & witness-chain preservation
+
+The non-negotiable invariant (ADR-136 §2.5–2.6, ADR-028): replaying recorded canonical bytes through the pipeline twice yields byte-identical outputs and equal BLAKE3 witness hashes. Strategy per component class:
+
+1. **Everything on the trust path implements `CanonicalFrame`.** New frame types (`MultiTaskOutput`, `PhysicsResidual`, `AdaptationStep`, edge events, NV frames) get fixed-field-order LE encodings and `witness_hash()`; encoders are the only serializers (no ad-hoc serde on the witness path).
+2. **Inference is witnessed by (input hash, model hash, output hash).** `model_id`/`model_version` on `FrameMeta` already bind frames to models; P1 adds a weights digest so the triple is closed. Pure-Rust f32 inference (ADR-146 ABI) with fixed reduction order; no GPU nondeterminism on the witness path — GPU/libtorch is training-only, and training determinism is pinned by the existing seeds (`proof.rs`: `PROOF_SEED = 42`, `MODEL_SEED = 0`).
+3. **Advisory vs witnessed split.** Components that cannot be made deterministic — the OccWorld Python subprocess (ADR-147), live MARL exploration, any future LLM/agent output (ADR-140 Ruflo) — are **advisory**: their outputs may bias estimates but never enter `to_canonical_bytes()` directly; instead the *decision to use them* is recorded (prior id + content hash) so replay reproduces the decision even if the producer cannot be re-run. The Kalman tracker consumes priors as explicit inputs recorded in the replay corpus.
+4. **Adaptation is a chain of witnessed steps.** P6's `AdaptationStep.witness` hashes (parent version ‖ delta ‖ acceptance result); the active model at any timestamp is reconstructible from the step chain — the model-weights analogue of the frame witness chain.
+5. **Edge parity.** P7 modules must produce the same `witness_digest` as the server-side reference implementation on the AC6 fixture; the module hash joins the firmware `source-hashes.txt` in the ADR-028 witness bundle.
+6. **Witness bundle growth is mechanical.** Each pillar adds expected-hash keys (`forward_model_residual_v1`, `edge_presence_replay_v1`, `nvsim` already ships `proof.rs`) to the existing `verify.py` chain rather than inventing new verification mechanisms.
+
+---
+
+## 6. Explicit non-goals
+
+- **No workspace rename or rewrite.** Reaffirms ADR-136 §2.1/§4.1: no `ruview_*` crate prefix migration, no umbrella crate; pillars land inside the existing crates listed above.
+- **No full-wave Maxwell solver in the runtime loop.** P2 is first-order Born/ray, with the approximation order declared. "Physics-informed" never means FDTD at 20 Hz.
+- **No long-range cardiac magnetometry claims.** P8 is bounded by the physics review in `docs/research/quantum-sensing/16-ghost-murmur-ruview-spec.md`; ranges beyond published MCG physics are out of scope permanently, not just deferred.
+- **No camera in any deployed serving graph** (P4 teachers are train-time, cached-label only) and **no identity recognition as a product feature** — identity embeddings remain in-RAM, hash-rotated (ADR-120 invariants).
+- **No weaponization or LAWS capability in P5**, per ADR-148 §1.3; swarm work targets SAR/MAT and stays behind the ADR-148 regulatory gates.
+- **No fabricated benchmarks.** All pillar performance statements in this document are targets; promotion of any pillar requires the ADR-145 ablation matrix delta plus pinned determinism hashes, in CI, before any external claim.
+- **No new verification mechanisms.** The witness chain extends `verify.py` / BLAKE3 / `expected_*.sha256`; we do not introduce a second, parallel proof system.
+
+---
+
+## 7. Open questions for the next document in this series
+
+1. Airborne CSI phase stability (P5): what does the ADR-138 clock-quality gate measure on a real quadrotor payload?
+2. Forward-model fidelity floor (P2): what Born-residual magnitude on the ADR-135 empty-room captures is "good enough" to be a useful contradiction signal?
+3. Replay-corpus governance (Phase 0): retention, privacy class of recorded canonical bytes, and consent — the recorder stores signal evidence, which is itself sensitive.

+# Beyond-SOTA Validation, Test & Benchmark Methodology
+
+**Series:** `docs/research/ruview-beyond-sota/` · Document 03
+**Date:** 2026-06-09
+**Scope:** How RuView proves (and gates) beyond-SOTA claims using the verification
+infrastructure that already exists in this repository. Every number below is sourced
+from a cited file in this repo; nothing is invented.
+
+---
+
+## 1. The Layered Validation Pyramid
+
+Six layers, cheapest/most-deterministic at the bottom, most expensive/most-credible at
+the top. A beyond-SOTA claim must survive **every layer below it** before it may be
+published from the layer it lives at.
+
+| Layer | What it proves | Tooling | Frequency | Determinism |
+|-------|----------------|---------|-----------|-------------|
+| **L0** Unit/integration tests | Code correctness | `cargo test --workspace --no-default-features` + pytest | per commit | exact |
+| **L1** Deterministic proof + witness bundle | Pipeline is real, unchanged, reproducible | `archive/v1/data/proof/verify.py`, `scripts/generate-witness-bundle.sh` | per merge / release | exact (SHA-256) |
+| **L2** Criterion micro-benchmarks | Compute latency only — never quality (ADR-149 §2) | 15 bench targets across `v2/crates/*/benches/` | nightly / pre-release | statistical |
+| **L3** Dataset-level accuracy eval | Pose/presence/vitals quality vs published SOTA | MM-Fi / Wi-Pose (ADR-015), `ruview_metrics.rs` tiers, ADR-145 ablation harness | per model release | seeded |
+| **L4** Hardware-in-loop | Real CSI on real ESP32, no mocks | COM9 (S3) / COM12 (C6) protocol, witness firmware hashes | per firmware release | A/B controlled |
+| **L5** Field trials / live capture | End-to-end behavior in a real room | live-session captures (e.g. `benchmark_baseline.json`) | campaign | statistical |
+
+### 1.1 L0 — Workspace tests (current counts)
+
+- ADR-028 audit (2026-03-01): **1,031 passed, 0 failed, 8 ignored** for
+  `cargo test --workspace --no-default-features`
+  (`docs/adr/ADR-028-esp32-capability-audit.md` §2).
+- Current `CHANGELOG.md` (Unreleased, cross-platform fix entry): **2,682 workspace
+  tests pass / 0 fail on Windows** — the suite has more than doubled since the audit.
+- `CLAUDE.md` pre-merge gate still cites "1,031+ passed, 0 failed" as the floor.
+
+**Rule:** the post-change test count may never be lower than the pre-change count, and
+failures must be 0. The witness bundle records the full log
+(`test-results/rust-workspace-tests.log`) and an aggregated `summary.txt`
+(`scripts/generate-witness-bundle.sh` step 3).
+
+### 1.2 L1 — Deterministic proof ("Trust Kill Switch") + witness bundle
+
+`archive/v1/data/proof/verify.py` (header comment): feeds 1,000 synthetic CSI frames
+(seed=42, `sample_csi_data.json`) through the **production** `CSIProcessor`
+(`src/core/csi_processor.py`), hashes the first 100 frames' feature output
+(`VERIFICATION_FRAME_COUNT = 100`), and compares against
+`archive/v1/data/proof/expected_features.sha256`.
+
+- **Current published hash (file contents, verified during this investigation):**
+  `f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a`
+- The hash is **environment-coupled** and has been legitimately regenerated before:
+  ADR-028 §5.3 recorded `8c0680d7…` under numpy 2.4.2/scipy 1.17.1; `CHANGELOG.md`
+  (#560 fix) recorded `667eb054…` after 6-decimal quantization + single-thread BLAS
+  pinning (`OMP_NUM_THREADS=1` etc.). Each regeneration must follow the documented
+  procedure: `python verify.py --generate-hash` then `python verify.py` → `VERDICT: PASS`.
+
+`scripts/generate-witness-bundle.sh` packages: witness log + ADR-028, the Python proof
+(verify.py + expected hash + reference-signal metadata), full Rust test log + summary,
+the ADR-134 CIR proof, firmware source/binary SHA-256s, crate version manifest, npm
+tarball SHA-256, and a recipient-side `VERIFY.sh`.
+
+**Accuracy note on check counts:** `CLAUDE.md` describes the recipient verification as
+"7/7 PASS"; the current `VERIFY.sh` embedded in the script performs **10** `check()`
+assertions (witness log, ADR, proof-hash file, tests, firmware hashes, crate manifest,
+npm manifest, Python proof, CIR proof, CIR hash file) but prints a hardcoded
+`"ALL CHECKS PASSED (8/8)"` string (`generate-witness-bundle.sh` line 293). The
+hardcoded count is stale relative to the actual check list — fix it to print
+`${PASS_COUNT}/${PASS_COUNT+FAIL_COUNT}` so the verdict can never silently desynchronize
+from the check inventory.
+
+### 1.3 L2 — Criterion micro-benchmark inventory (all 15 targets)
+
+All bench sources read directly. Per ADR-149 §2 these are **latency regression gates
+only, never quality evidence**.
+
+| Bench target | Crate | Benchmark functions / groups | What it measures | Recorded value or in-source target (citation) |
+|---|---|---|---|---|
+| `engine_cycle.rs` | wifi-densepose-engine | `process_cycle_4nodes_56sc` | One full `StreamingEngine::process_cycle` (fuse + quality + calibration provenance + privacy gate + WorldGraph node), 4-node/56-subcarrier ESP32-S3 HT20 mesh | Budget: **50 ms** (20 Hz) — bench header |

+| `sketch_bench.rs` | wifi-densepose-ruvector | `compare_d128/256/512` × `float_l2`/`float_cosine`/`sketch_hamming` | ADR-084 sketch-vs-float per-pair compare cost (AETHER 128-d, spectrogram 256-d) | Pass: **sketch ≥8× faster** at every dim (ADR-084 threshold 8×–30×) — bench header |
+| `crv_bench.rs` | wifi-densepose-ruvector | `gestalt_classify_single/batch_100`, `sensory_encode_single`, `pipeline_full_session`, `convergence_two_sessions`, `crv_session_create`, `crv_embedding_dimension_scaling` (32/128/384), `crv_stage_vi_partition` | CRV integration throughput | no recorded baseline |
+| `inference_bench.rs` | wifi-densepose-nn | `tensor_ops` (relu/sigmoid/tanh), `densepose_inference`, `translator_inference`, `mock_inference`, `batch_inference` | NN forward-pass cost by input/batch size | no recorded baseline; **`mock_inference` group must never be quoted as a pipeline number** (§6) |
+| `training_bench.rs` | wifi-densepose-train | `interp_114_to_56_batch32`, `interp_scaling`, `compute_interp_weights_114_56`, `synthetic_dataset_get`, `synthetic_epoch`, `config_validate`, PCK over 100 samples | Training preprocessing + metrics hot paths; fixtures fully deterministic (no `rand`) — header | no recorded baseline |
+| `detection_bench.rs` | wifi-densepose-mat | `breathing_detection`, `heartbeat_detection`, `movement_classification`, `detection_pipeline`, localization (triangulation/depth), alert generation | MAT survivor-detection algorithms at varying signal lengths / noise | no recorded baseline |

+| `mqtt_throughput.rs` | wifi-densepose-sensing-server | `discovery::build_*`, `state::*`, `rate_limiter::allow_*`, `privacy::decide_*`, `semantic::bus_tick_all_10_primitives` | ADR-115 MQTT hot path | Targets (header): discovery **<5 µs**, state encode **<2 µs**, rate limit **<100 ns**, privacy **<50 ns**, bus tick **<10 µs** |

+
+**Honest gap — `benchmark_baseline.json` is not a criterion baseline.** The repo-root
+`benchmark_baseline.json` (369.9 KB) contains **1,566 live-capture samples** from a
+2-node session (fields: `tick`, `n_nodes`, `variance`, `motion`, `presence`,
+`confidence`, `est_persons`, `n_persons_rendered`, `kp_spread`, `rssi`) plus a summary
+block — it records **field-trial telemetry (L5)**, not micro-benchmark latencies.
+No file in the repo references it (`grep -rn benchmark_baseline` → 0 hits outside the
+file itself); its producer must be identified and committed (§5.3). Summary values
+(all from the file's `summary` object):
+
+| Metric | Baseline value |
+|---|---:|
+| `total_frames` | 1,566 |
+| `presence_ratio` | 0.9336 (1,462/1,566 frames presence-true) |
+| `confidence_mean` | 0.6433 |
+| `variance_mean` / `variance_std` | 109.36 / 154.13 |
+| `kp_spread_mean` / `kp_spread_std` | 86.73 / 4.52 |
+| `person_count_changes` | 10 |
+
+Criterion latencies that *have* been recorded live in ADR documents instead
+(ADR-147-benchmark-proof.md, ADR-149 §4.3, CHANGELOG Performance) — §5 below defines
+how to consolidate them into a real machine-readable criterion baseline.
+
+### 1.4 L3 — Dataset-level accuracy evaluation
+
+- **Datasets (ADR-015):** primary **MM-Fi** (40 subjects × 27 actions × ~320K frames,
+  1TX×3RX, 114 subcarriers @100 Hz, 17-keypoint COCO + DensePose UV, CC BY-NC 4.0);
+  secondary **Wi-Pose** (12 volunteers × 12 actions × 166,600 packets, 3×3, 30
+  subcarriers). 114→56 subcarrier interpolation via `subcarrier.rs`; validation split =
+  subjects 33–40 held out (ADR-015 Phase 1).
+- **Acceptance tiers:** `wifi-densepose-train/src/ruview_metrics.rs` —
+  PCK@0.2 / OKS / MOTA / vitals rolled into `RuViewTier`
+  (Fail/Bronze/Silver/Gold) (ADR-145 §1.1).
+- **Ablation harness (ADR-145):** 6-variant matrix (`csi_only`, `cir_only`,
+  `csi_plus_cir`, `plus_doppler`, `plus_bfld`, `plus_uwb`-skipped), each variant
+  producing acceptance tier + `SpecMetrics` (presence ≥0.90, localization ≤0.50 m,
+  activity ≥0.70, FP ≤0.05, FN ≤0.10), `LatencyProfile` (p95 ≤100 ms), and
+  `PrivacyLeakage` (MIA `leakage_score` ≤0.05), SHA-256-pinned per variant under
+  `PROOF_SEED=42` (ADR-145 §2.2–2.6). Built at commit `0f336b7d3` (ADR-145
+  implementation status); CLI auto-mode wiring is pending.
+- **Cross-environment:** ADR-027 MERIDIAN `CrossDomainEvaluator`
+  (`wifi-densepose-train/src/eval.rs`) — `domain_gap_ratio`, extended by ADR-145
+  `cross_room_degradation()` with a 17-joint PCK-delta heatmap.
+
+### 1.5 L4 — Hardware-in-loop
+
+- Real CSI nodes: ESP32-S3 on **COM9**, ESP32-C6 + MR60BHA2 on **COM12** (`CLAUDE.md`
+  hardware table). ADR-018 binary frame protocol over UDP:5005 (ADR-028 §3.2/§3.4).
+- ADR-145 Tier-4 test (gated, `#[cfg(feature = "hardware-test")]`): replay a live 30 s
+  COM9 capture through `csi_only` and `csi_plus_cir`; assert no presence regression and
+  p95 < 100 ms.

+### 1.6 L5 — Field trials
+
+Live multi-node sessions captured as JSONL/JSON with summary statistics —
+`benchmark_baseline.json` (§1.3) is the existing exemplar. ADR-149 §6 adds the seeded
+`evals/` episode harness (Stage 1 kinematic full-matrix, Stage 2 Gazebo/PX4 SITL on the
+3 median seeds) for the swarm domain.
+
+---
+
+## 2. Beyond-SOTA Acceptance Criteria per Capability Axis
+
+A claim is "beyond SOTA" only with: a named external baseline, an exact metric and
+protocol match, the dataset/split named, the threshold pre-registered, and the
+statistical procedure of §3 followed. Current axes with measured status:
+
+| Axis | Metric (exact) | Dataset / protocol | SOTA baseline | Beyond-SOTA threshold | Measured status (cited) |
+|---|---|---|---|---|---|
+| In-domain pose accuracy | torso-PCK@20: `‖pred−gt‖ ≤ 0.2·‖R-shoulder−L-hip‖` | MM-Fi `random_split` (ratio 0.8, seed 0) | MultiFormer **72.25%** (Table VII); CSI2Pose 68.41% | > 72.25% with 95% CI lower bound above it | Flagship **83.59%**; micro (75,237 params) **74.30%** (`docs/benchmarks/wifi-pose-efficiency-frontier.md`) |
+| Edge efficiency frontier | torso-PCK@20 at deployed precision + params + batch-1 latency | same | MultiFormer 72.25% at full size | Pareto-dominance: smaller **and** above 72.25% at the deployed precision | int8 73.5 KB **74.70%**; int4-QAT 36.7 KB **74.46%**; shipped int4 verified **74.08%**, 0.135 ms 1-thread x86 (same file) |
+| Cross-subject generalization | torso-PCK@20, official MM-Fi cross-subject split (256,608 train / 64,152 test) | leakage-free split | own zero-shot baseline 63.99% | ADR-150 §4 gate: **+≥6 pts cross-subject without losing >2 pts random-split** | Best zero-shot **64.92%** (mixup+TTA+3-seed); gate judged unreachable without new capture (ADR-150 §3.2) |
+| Few-shot calibration (deployment) | PCK@20 after K labeled in-room samples; adapter size | MM-Fi cross-subject & cross-environment splits | zero-shot (64% / 10.6%) | SOTA-level (≳72%) from ≤200 samples with ≤~11 KB per-room adapter | cross-subject ~**72%** @100–200 samples (3 seeds); cross-env **10.6→73.1%** @200, 60.1% @5 (ADR-150 §3.5–3.6) |
+| Swarm SAR localization | CEP50/CEP95 (m), GDOP-stratified | seeded episode distribution (ADR-149 §6), not single geometry | Wi2SAR **5 m** (arxiv 2604.09115, paper-to-paper) | CEP50 < 5 m, IQM over ≥10 seeds, 95% CI excluding 5 m | 1.732 m single synthetic geometry — graded **Low–Medium**, not yet claimable (ADR-149 §7) |
+| Swarm coverage | coverage-rate@240 s; time-to-95% | episode rollouts | Wi2SAR 160k m²/13.5 min | rollout (not analytic) mean+CI beating baseline | 223 s is an analytic estimate — graded **Low** (ADR-149 §7) |
+| Control-loop latency | criterion wall-clock | local hardware, named | 10 ms / 100 Hz budget | all stages ≪ budget | 3.3 µs MARL / 43 µs RRT-APF / 54 ns fusion / 248 µs PPO (ADR-149 §4.3) |
+| World-model trajectory | MDE (m) at 5-frame horizon | RuView CSI-derived occupancy | pre-fine-tune random-weight baseline 9.49 m MDE | **≤1.0 m (2.0 vox)** at 5-frame horizon (ADR-147 §5 target, cited in benchmark-proof §4) | 9.49 m / FDE 16.23 m random weights; 208.45 ms median latency on real CSI (ADR-147-benchmark-proof §4, §7) |
+| Privacy leakage | MIA `leakage_score = 2·(AUC−0.5)` | fixed replay, fixed-seed shadow classifier | chance (0) | ≤ **0.05** (attacker AUC ≤ 0.525) | gate defined, harness built (ADR-145 §2.3) |
+| Vitals (hardware) | BPM error vs wearable ground truth | live A/B board protocol | control board behavior | within physiological agreement of ground truth, stable spread | 88–91 BPM vs 87 GT, spread 59→0 (CHANGELOG #987) |
+
+### Claim-language discipline (from ADR-149 §7 grading)
+
+| Evidence | Permitted language |
+|---|---|
+| Single run / single geometry / analytic estimate | "directional", never "beats SOTA" |
+| Seeded multi-run with CIs vs paper baseline | "exceeds the published X result paper-to-paper" |
+| Same metric, same split, same protocol, CI excludes baseline | "beyond SOTA on <dataset>/<split>" |
+| No public leaderboard exists (swarm CSI-SAR) | never claim "leaderboard standing" (ADR-149 §3) |
+
+---
+
+## 3. Statistical Procedure for Honest Claims
+
+Adopted from ADR-149 §5 (Agarwal 2021 / Gorsane 2022 standard) and the practices
+already used in ADR-150/efficiency-frontier measurements:
+
+1. **Seeds.** ≥10 independent seeds for RL/episodic claims (ADR-149 §5); ≥3 seeds
+   minimum for supervised dataset evals (ADR-150 §3.5 used 3 seeds; report all).
+   Training seeds, eval seeds, and split files are versioned and committed.
+2. **Aggregate.** IQM (not mean/median) for episodic metrics + performance profiles;
+   for dataset accuracy report mean across seeds with each seed's value listed.
+3. **Confidence intervals.** 95% stratified bootstrap, 1,000 resamples (ADR-149 §5;
+   reference impl: `rliable`).
+4. **Paired comparisons.** When comparing model A vs B (e.g. `csi_plus_cir` vs
+   `csi_only`, or ours vs a reproduced baseline), evaluate both on the **identical
+   frozen test frames** and use a paired bootstrap over per-sample correctness
+   (PCK hit/miss is per-joint binary — pair at the joint-sample level). For
+   paper-to-paper comparisons where the baseline cannot be re-run, state so
+   explicitly ("paper-to-paper", ADR-149 §2) and require the CI lower bound to clear
+   the published point value.
+5. **Pre-registration.** The threshold lives in an ADR **before** the run
+   (precedent: ADR-150 §4 gate written before §3.2 measurements; the measurements
+   honestly reported the gate as not met).
+6. **Negative results are recorded.** ADR-150 §1/§3.2 keeps DANN-failed,
+   capacity-hurts, and KD-didn't-help results in the record — required practice.
+7. **Eval episodes (swarm):** 50 fixed, versioned episodes per policy
+   (10 victim layouts × 5 CSI-noise levels), ≥3 baselines (random walk,
+   boustrophedon+triangulation, IPPO) (ADR-149 §5).
+8. **GDOP stratification** for any localization claim, so geometry artifacts cannot
+   produce the headline (ADR-149 §6.3).
+
+---
+
+## 4. Regression-Gate Design (CI Enforcement)
+
+### 4.1 Three gate classes, three tolerances
+
+| Gate class | Source of truth | Tolerance | On breach |
+|---|---|---|---|
+| Determinism hashes | `expected_features.sha256`, `expected_cir_features.sha256`, `expected_calibration_features.sha256`, future `expected_ablation_<slug>.sha256` | **exact (0%)** | exit 1 = FAIL; exit 2 = SKIP only for placeholder hashes (proof.rs `0/1/2` convention, ADR-145 §2.4) |
+| Accuracy / quality metrics | per-variant canonical bytes, quantized 1e-3 (ADR-145 §2.6) | exact after quantization | FAIL CI; tier change requires ADR amendment |
+| Latency / throughput | criterion estimates JSON | **% tolerance per scale** (below) | FAIL on regression beyond tolerance; trend everything |
+
+### 4.2 Criterion baseline file (replaces the current gap)
+
+Today criterion numbers live in prose (ADR-147-benchmark-proof, ADR-149 §4.3,
+CHANGELOG). Formalize:
+
+1. `cargo bench --workspace -- --save-baseline main` on a **named, fixed runner**
+   (ADR-147 used RTX 5080 / specific host; record host + toolchain in the file).
+2. Export `target/criterion/*/estimates.json` point estimates into a committed
+   `v2/benchmarks/criterion-baseline.json`: `{bench_id, crate, p50_ns, host, commit}`.
+3. CI compares new runs against it with scale-aware tolerance — wall-clock noise is
+   proportionally larger at small magnitudes:
+
+| Magnitude | Tolerance | Rationale |
+|---|---|---|
+| < 1 µs (e.g. fusion 54 ns, privacy decide <50 ns target) | ±25% | timer/jitter dominated |
+| 1 µs – 1 ms (MARL 3.3 µs, RRT-APF 43 µs, PPO 248 µs) | ±15% | criterion CI typically <5%, leave CI-runner headroom |
+| > 1 ms (engine cycle vs 50 ms budget, OccWorld ~209 ms) | ±10% **and** absolute budget (50 ms / 500 ms ADR-147 §6) | budgets are the contract |
+
+4. Hard in-source acceptance thresholds remain authoritative regardless of baseline:
+   sketch ≥8× (`sketch_bench.rs`), prefilter ≥4× (`aether_prefilter_bench.rs`),
+   nvsim ≥1 kHz (`pipeline_throughput.rs`), MQTT header targets, ADR-145 p95 ≤100 ms.
+5. Latency stays **out of determinism hashes** (ADR-145 §2.6) but **in** the trended
+   `summary.json`, so sub-threshold drift is visible (ADR-145 §3.2 mitigation).
+
+### 4.3 Live-capture baseline gate (`benchmark_baseline.json`)
+
+Adopt the file as the L5 regression anchor with documented provenance, then gate a
+re-capture of the same scenario (same 2-node placement, same room class) against the
+summary block:
+
+| Field | Baseline | Suggested gate |
+|---|---:|---|
+| `presence_ratio` | 0.9336 | ≥ 0.90 for an occupied-room session |
+| `confidence_mean` | 0.6433 | within ±0.10 |
+| `kp_spread_std` | 4.52 | ≤ 2× baseline (skeleton stability) |
+| `person_count_changes` | 10 / 1,566 frames | ≤ 2× baseline (count flapping — see CHANGELOG #803/#894 clamp bugs this metric would have caught) |
+
+Field-trial gates are **soft** (warn + require human sign-off), never auto-merge
+blockers — environments differ; the gate exists to force an explanation.
+
+### 4.4 Wiring
+
+Pre-merge (`CLAUDE.md` checklist): L0 + L1. Nightly: L2 criterion + ADR-145 Tier-3
+ablation matrix (minutes-scale, ADR-145 §3.2). Release: full witness bundle +
+`VERIFY.sh` + L4 on real COM-port hardware (`CLAUDE.md` firmware rule 6/7).
+
+---
+
+## 5. Reproducibility & External-Witness Requirements
+
+Anyone outside the project must be able to re-run every claimed result:
+
+1. **One command per layer.** `cargo test --workspace --no-default-features`;
+   `python archive/v1/data/proof/verify.py`; `bash scripts/generate-witness-bundle.sh`
+   then `bash VERIFY.sh` inside the bundle; per ADR-150 §4 every accuracy result needs
+   "one-command reproduction" (efficiency frontier publishes its exact command:
+   `python aether-arena/staging/train_efficiency_pareto.py npy/X.npy npy/Y.npy npy/split_random.npy`).
+2. **Pinned numerical environment.** The Python proof requires single-threaded BLAS
+   (`OMP_NUM_THREADS=1`, `OPENBLAS_NUM_THREADS=1`, `MKL_NUM_THREADS=1`,
+   `VECLIB_MAXIMUM_THREADS=1`, `NUMEXPR_NUM_THREADS=1`) and 6-decimal quantization
+   (`HASH_QUANTIZATION_DECIMALS=6`) — the #560 fix in `CHANGELOG.md`; Rust proof
+   runners use coarse u16 quantization at 1e-3 in natural order
+   (`calibration_proof_runner.rs` pattern, ADR-145 §2.6) for libm portability.
+3. **Seeds are constants, committed:** `PROOF_SEED=42`, `MODEL_SEED=0`
+   (`proof.rs`, ADR-015 Phase 5); dataset splits committed as `.npy`
+   (`split_random.npy`); swarm configs as versioned YAML with all seeds (ADR-149 §5).
+4. **Artifacts carry hashes.** Published model artifacts include SHA-256 (HuggingFace
+   `pose_micro_int4.npz`, sha256 `c03eeb…` — efficiency-frontier doc); witness bundle
+   has a `MANIFEST.sha256` over every file; provenance fields
+   (`replay_sha256`, `model_sha256`, `calibration_version`, `privacy_mode`) are bound
+   into ablation proof hashes (ADR-145 §2.7) so a metric cannot be quoted without its
+   exact model + calibration + privacy decision.
+5. **Hardware claims name the hardware.** ADR-147 records RTX 5080 / CUDA 12.8 /
+   PyTorch 2.10.0; nvsim states the Cortex-A53 scaling caveat in the bench header;
+   efficiency-frontier flags ARM validation as pending. Copy this discipline.
+6. **Witness rows.** Every new proof gains rows in `docs/WITNESS-LOG-028.md`
+   (ADR-145 §5.3 adds W-39…W-41) and the bundle's `source-hashes.txt`.
+7. **Secret hygiene in evidence.** Bundle logs pass through
+   `scripts/redact-secrets.py` (ADR-110 wave-5 incident note in
+   `generate-witness-bundle.sh` step 4) — external evidence must never embed `.env`.
+
+---
+
+## 6. Known Measurement Pitfalls (WiFi-sensing specific)
+
+| # | Pitfall | Repo evidence | Mitigation in this methodology |
+|---|---|---|---|
+| 1 | **Subject leakage / split optimism.** In-domain `random_split` has temporal/subject-adjacency effects; the same model family scores 83.6% random-split but ~11.6% torso-PCK on the leakage-free cross-subject split | efficiency-frontier "Controlled claim" footnote; ADR-150 §1, §3.2 | Always report the split name; publish random-split and cross-subject numbers side by side; cross-subject claims only on the official split |
+| 2 | **Per-environment overfitting.** Zero-shot cross-environment collapses to 10.6%; subject-scaling saturates ~63.7% past 16–20 subjects because the residual is room/device shift | ADR-150 §3.3, §3.6 | Cross-room degradation + 17-joint heatmap in every ablation (ADR-145 §2.5); claim deployment accuracy only with the calibration protocol stated (K samples, adapter size) |
+| 3 | **Mock-mode contamination.** Mock firmware missed a real Kconfig threshold bug; the nn crate ships a `mock_inference` criterion group that must never be quoted as pipeline performance | `CLAUDE.md` firmware rule 7; `inference_bench.rs` `bench_mock_inference` | L4 mandatory before firmware release ("Always test with real WiFi CSI, not mock mode"); label mock benches in reports; ADR-147 §7 re-ran the benchmark on real CSI explicitly "no mocks" |
+| 4 | **Single-run point estimates.** 1.732 m localization from one synthetic geometry; 223 s coverage from an analytic formula | ADR-149 §1, §7 | §3 seed/CI protocol; evidence-grade table before publication |
+| 5 | **Random-weight / untrained baselines read as results.** OccWorld MDE 9.49 m is a pre-fine-tuning random-weight reading | ADR-147-benchmark-proof §4 | Label baseline-vs-target explicitly; never aggregate untrained-model numbers into capability claims |
+| 6 | **Latency conflated with quality.** Criterion µs numbers prove no compute bottleneck, nothing about accuracy | ADR-149 §2, §4.3 | L2 is gate-only; quality claims live in L3+ |
+| 7 | **Floating-point nondeterminism breaking proofs.** SciPy FFT SIMD reordering + multithreaded BLAS produced different hashes across CI microarchitectures | CHANGELOG #560; `calibration_proof_runner.rs` lines 1–13 (cited in ADR-145 §2.3) | Quantize before hashing; pin thread env vars; exclude wall-clock from hashes |
+| 8 | **Hash churn without procedure.** Three distinct historical values of the proof hash exist (`8c0680d7…` ADR-028, `667eb054…` CHANGELOG #560, `f8e76f21…` current file) | cited files | Every regeneration via `--generate-hash` + re-verify + CHANGELOG entry + witness bundle refresh |
+| 9 | **Aggregation bugs masking accuracy.** Person count clamped to 1 by EMA mapping; eigenvalue path leaking counts up to 10; both invisible to unit tests for months | CHANGELOG #803, #894 | L5 summary gates on `person_count_changes`/count distributions; convergence tests replaying the live loop |
+| 10 | **Stale verification claims.** `VERIFY.sh` prints hardcoded "(8/8)" over 10 actual checks; `CLAUDE.md` says "7/7" | `generate-witness-bundle.sh` line 293; `CLAUDE.md` | Compute the verdict count; audit doc claims against scripts each release |
+| 11 | **Licensing limits on the eval set.** MM-Fi is CC BY-NC — weights trained solely on it cannot back commercial claims | ADR-015 Consequences | Track dataset license alongside every published number |
+
+---
+
+## 7. Gap List (what must be built to fully execute this methodology)
+
+| Gap | Owner layer | Source |
+|---|---|---|
+| Machine-readable criterion baseline (`v2/benchmarks/criterion-baseline.json`) + CI comparison job | L2 | §4.2 (numbers currently only in ADR prose) |
+| Provenance + producer script for `benchmark_baseline.json`; soft-gate job | L5 | §1.3, §4.3 (zero code references today) |
+| `ruview-cli --ablation mode=auto` wiring + `expected_ablation_<slug>.sha256` (currently placeholders → exit 2) | L3 | ADR-145 implementation status |
+| Seeded swarm `evals/` harness + `evals/RESULTS.md` internal leaderboard | L3/L5 | ADR-149 §6, §8 open issues |
+| Fix `VERIFY.sh` hardcoded verdict count; reconcile `CLAUDE.md` "7/7" | L1 | §1.2 |
+| Curated paired room-A/room-B labeled replay set (frozen, SHA-pinned, never trained on) | L3 | ADR-145 §3.2 |
+| ARM/edge on-device latency validation for the int4 model (x86-only today) | L4 | efficiency-frontier doc ("Pi fleet pending") |
+| Bench validation of the antenna-placement matrix on real hardware | L4 | PRODUCTION-ROADMAP.md Tier 2.3 |
+
+---
+
+## Update — falsifiable occupancy benchmark implemented
+
+`wifi-densepose-train::occupancy_bench` (added this branch) makes the
+presence/person-count claim **falsifiable in code**, directly enforcing the L3
+discipline above. It grades predictions vs ground truth and gates a SOTA claim
+behind a single `claim_allowed` invariant that requires **all** of:
+
+1. `DataProvenance::Measured` — synthetic/mock data is scorable for regression
+   but **never claimable** (anti-mock-contamination; the CLAUDE.md Kconfig-bug
+   lesson made structural).
+2. A leak-free `EvalSplit` — `validate()` refuses any split where a subject *or*
+   environment id appears in both train and test (subject leakage / per-env
+   overfitting).
+3. `n_test ≥ min_test_samples` (small-N guard).
+4. Presence F1 whose **bootstrap-CI lower bound** (deterministic splitmix64,
+   seeded) clears the threshold — not the point estimate.
+5. Count MAE within threshold.
+
+The claim string is unreadable except through the gate (returns `NO_CLAIM`
+otherwise) — same discipline as the `ruview-gamma` acceptance gate. 10 tests
+cover each refusal path. What remains is *data*, not *method*: feed it a frozen,
+SHA-pinned, subject/environment-disjoint **measured** replay set (the curated
+room-A/room-B item above) and the "beyond SOTA" claim becomes a passing or
+failing test, not a slogan.

+# RuView Beyond-SOTA — 04: Performance Review & Optimization Roadmap
+
+**Scope:** the streaming sensing pipeline (CSI ingest → multistatic fusion → CIR gate →
+pose publish) in `v2/`, hot-path crates `wifi-densepose-signal` (ruvsense),
+`wifi-densepose-engine`, `wifi-densepose-ruvector`, plus build-profile and edge-target
+(Pi 5-class, WASM) considerations.
+
+**Hard constraint (non-negotiable):** the witness chain (ADR-028, ADR-136 §2.5 replay
+contract, ADR-137 §2.7 BLAKE3 witness in
+`v2/crates/wifi-densepose-engine/src/lib.rs:437-448`) requires **bit-exact deterministic
+float output**. Every recommendation below is tagged with its determinism risk. Anything
+that reorders float additions, enables FMA contraction, fast-math, or parallel reduction
+**changes the witness hash** and requires a coordinated proof-hash regeneration
+(`verify.py --generate-hash`) plus witness-bundle re-issue.
+
+---
+
+## 1. What we actually have measured (and what we don't)
+
+`/home/user/RuView/benchmark_baseline.json` is a **signal-quality soak baseline**, not a
+latency benchmark: 1,566 samples (ticks 51131–52395) of
+`variance / motion / presence / confidence / est_persons / kp_spread / rssi`, with a
+summary block (`confidence_mean: 0.643`, `presence_ratio: 0.934`,
+`kp_spread_mean: 86.7`, `person_count_changes: 10`). **It contains zero timing data.**
+It is the accuracy guardrail for any optimization (post-change soak must reproduce these
+distributions), not a latency baseline.
+
+Latency benchmarks exist but no committed results were found in the repo:
+
+| Bench | File | What it measures |
+|---|---|---|
+| `process_cycle_4nodes_56sc` | `v2/crates/wifi-densepose-engine/benches/engine_cycle.rs:34-48` | One full engine cycle, 4 nodes × 56 subcarriers, vs. the documented 50 ms budget (`engine_cycle.rs:3-6`) |
+| `cir_bench` | `v2/crates/wifi-densepose-signal/benches/cir_bench.rs` | `CirEstimator::estimate()` per tier (HT20/HT40/HE20/HE40) + 12-link amortization |
+| `sketch_bench` | `v2/crates/wifi-densepose-ruvector/benches/sketch_bench.rs:86-175` | Hamming sketch vs. float L2/cosine compare; top-K over 1,024-sketch bank |
+| `signal_bench`, `calibration_bench`, `aether_prefilter_bench` | `v2/crates/wifi-densepose-signal/benches/` | Signal-path and ADR-135 calibration throughput |
+
+**Action zero of the roadmap is to run these on a Pi 5 and commit the criterion
+baselines.** All impact classes below are derived from operation counts read out of the
+code (cited), not invented measurements.
+
+---
+
+## 2. Latency budget model — streaming pipeline
+
+Two clock domains exist and must not be conflated:
+
+- **TDMA sensing cycle: 20 Hz / 50 ms** — the architecture's own budget
+  (`v2/crates/wifi-densepose-signal/src/ruvsense/mod.rs:5`, `RuvSenseConfig::target_hz =
+  20.0` at `mod.rs:258`, and the bench doc `engine_cycle.rs:3`).
+- **CSI ingest: 100 Hz per node** — raw frames arrive ~5× faster than the fused output
+  rate; per-frame ingest work (parse, normalize, calibrate, window) must therefore fit a
+  **10 ms** per-frame envelope while the fused path fits **< 50 ms end-to-end**.
+
+Proposed per-stage budget for the 50 ms end-to-end target (4 nodes, HT20 / 56
+subcarriers — the configuration the engine bench encodes):
+
+| # | Stage | Code | Budget | Risk (from code reading) |
+|---|---|---|---|---|
+| 1 | Ingest + hardware normalize (per 100 Hz frame) | `hardware_norm`, `multiband.rs` | 2 ms | Low — vector ops on 56 floats |
+| 2 | Calibration apply (ADR-135) | `ruvsense/calibration.rs` | 2 ms | Low — Welford lookups |
+| 3 | Phase alignment | `phase_align.rs:117-152` | 1 ms | Low — ≤ 20 iterations over ≤ 17 static subcarriers (`config.max_iterations: 20`, `phase_align.rs:57`); allocation churn only (§3) |
+| 4 | Multistatic fusion (attention + softmax) | `multistatic.rs:512-598` | 2 ms | Low — O(nodes × 56); but does duplicate work in `fuse_scored` (§3, F2) |
+| 5 | **CIR gate (ISTA L1)** | `multistatic.rs:440-475` → `cir.rs:601-654` | 15 ms | **HIGH** — dominant cost, scales badly with PHY tier (below) |
+| 6 | Coherence score + gate decision | `coherence.rs`, `coherence_gate.rs` | 2 ms | Low — z-scores over 56 subcarriers |
+| 7 | Tomography (ADR-030 tier 2, when enabled) | `tomography.rs:236-323` | 8 ms | **Medium** — per-iteration allocation + loose step size (§3, F8/F9) |
+| 8 | Pose tracker (17-kp Kalman + re-ID) | `pose_tracker.rs` | 8 ms | Medium — sketch prefilter (ADR-084) already mitigates the re-ID scan |
+| 9 | Engine: quality score, privacy gate, WorldGraph node, BLAKE3 witness | `engine/src/lib.rs:304-368` | 5 ms | Low per cycle, but **unbounded memory growth** (§4) |
+| 10 | Publish (WS/serde) | sensing-server | 5 ms | Low |
+| | **Total** | | **50 ms** | |
+
+### Why stage 5 is the at-risk stage — operation counts from the code
+
+`ista_solve` (`cir.rs:601-654`) runs **two dense complex mat-vecs per iteration**
+(`matvec_phi` at `cir.rs:717-726`, `matvec_phi_h` at `cir.rs:730-745`), each O(K·G)
+complex MACs (≈ 8 FLOPs each), up to `max_iters: 100` (`cir.rs:176`). Per
+`CirConfig` (`cir.rs:164-233`):
+
+| Tier | K (active) | G (taps) | FLOPs/iter (2·K·G·8) | FLOPs @100 iters |
+|---|---|---|---|---|
+| HT20 | 52 | 156 | ≈ 0.13 M | ≈ 13 M |
+| HT40 | 114 | 342 | ≈ 0.62 M | ≈ 62 M |
+| HE20 | 242 | 726 | ≈ 2.8 M | ≈ 0.28 G |
+| HE40 | 484 | 1,452 | ≈ 11.2 M | ≈ 1.1 G |
+
+HT20 fits the 15 ms budget comfortably on a Pi 5; **HE40 at worst-case iteration count
+is ~1.1 GFLOP of scalar, cache-unfriendly work per estimate and will not fit any 50 ms
+budget without structural change** (F4 below). Today the gate runs once per cycle on the
+first link only (`multistatic.rs:452-463`), which contains the damage; the 12-link
+amortization pattern in `cir_bench.rs` shows the intended scale-up, which multiplies
+this cost ×12.

+
+## 3. Findings table — optimization opportunities
+
+Impact: relative cycle-time/memory effect at the 4-node HT20 operating point unless
+noted. Determinism: **EXACT** = bit-identical output guaranteed; **TIE** = only
+tie-breaking/ordering may differ; **CHANGES-FLOATS** = output bits change, witness/proof
+hash must be regenerated.
+
+| ID | Finding (file:line) | Impact | Effort | Determinism |
+|---|---|---|---|---|
+| F1 | `FusedSensingFrame` deep-copies every input frame each cycle: `node_frames: node_frames.to_vec()` (`multistatic.rs:282`) — clones all per-node amplitude+phase vectors per 50 ms cycle even when downstream geometry consumers don't need them | Med | Low (Arc/Cow or borrow) | EXACT |
+| F2 | `fuse_scored` re-derives the per-node amplitude views and recomputes `node_attention_weights` after `fuse` already computed them inside `attention_weighted_fusion` (`multistatic.rs:311-321` duplicating `multistatic.rs:520`) — full cosine-sim + softmax done twice per cycle | Low-Med | Low (return weights from `fuse`) | EXACT (same math, computed once) |
+| F3 | CIR gate rebuilds a heap `CsiFrame` per cycle: `build_csi_frame_from_channel` allocates an `Array2<Complex64>` and converts amplitude/phase via `from_polar` per subcarrier (`multistatic.rs:488-506`, called from `multistatic.rs:462`), then `extract_csi_vector` converts back to `Complex32` (`cir.rs:505-530`) — f32→f64→f32 round-trip plus two allocations purely as glue | Med | Med (give `CirEstimator` a slice-based entry point) | EXACT if conversions reproduce exactly (f32→f64 is lossless; `from_polar` in f64 then truncate ≠ f32 polar — keep the f64 intermediate to stay exact, or accept CHANGES-FLOATS and regenerate hashes) |
+| F4 | ISTA inner loop uses dense O(K·G) mat-vecs (`cir.rs:717-745`) although Φ is a sub-sampled DFT (`cir.rs:539-558`) — the products Φx and Φᴴr are computable via an FFT of length G in O(G log G), an ~8–40× FLOP cut at HE20/HE40 (table §2) | **High** (the only path to HE40 real-time) | High | **CHANGES-FLOATS** (different summation order than the sequential dot product) — must ship behind a feature flag, A/B against `cir_proof_runner`, regenerate `expected_features.sha256` + witness bundle |
+| F5 | `neumann_warm_start` recomputes the diagonal of ΦᴴΦ with a full K×G pass **per frame** (`cir.rs:676-681`), rebuilds the COO→CSR diagonal matrix per frame (`cir.rs:683-685`), and collects `rhs_re`/`rhs_im` Vecs per frame (`cir.rs:689-690`) — yet `diag` depends only on Φ, which is fixed at `CirEstimator::new` | Med | Low (precompute diag+CSR in `new()`) | EXACT (same values, computed once) |
+| F6 | `phase_variance` collects a `Vec<f32>` of phases per call (`cir.rs:792`) — replaceable by a two-pass loop with zero allocation | Low | Low | EXACT |
+| F7 | Φ and Φᴴ are both stored densely (`cir.rs:546-547`): 2·K·G·8 bytes — Φᴴ entries are just conjugates of Φ (`cir.rs:555`), so a transposed-iteration kernel over Φ alone halves the footprint (HE40: 11.2 MB → 5.6 MB) | Low (latency) / Med (memory §4) | Med | EXACT (conjugation is exact; keep identical accumulation order in the transposed kernel) |
+| F8 | Tomography allocates the gradient vector **inside** the solver iteration loop: `let mut gradient = vec![0.0_f64; self.n_voxels]` (`tomography.rs:266`) — one heap alloc + zeroing per iteration, up to `max_iterations: 100` (`tomography.rs:75`); hoist and `fill(0.0)` | Med (for tier-2 deployments) | Low | EXACT |
+| F9 | Tomography step size uses the Frobenius-norm upper bound for the Lipschitz constant (`tomography.rs:253-259`, comment admits `‖WᵀW‖ ≤ ‖W‖_F²`) — a bound loose by up to the matrix rank, forcing proportionally more ISTA iterations than the power-method estimate used in `cir.rs:566-590` | Med | Low (reuse the cir.rs power-method pattern) | **CHANGES-FLOATS** (different step ⇒ different iterate path) |
+| F10 | `apply_phase_correction` clones the amplitude vector and allocates a fresh corrected-phase Vec per channel per cycle (`phase_align.rs:258-268`, `frame.amplitude.clone()` at `phase_align.rs:264`); `align` additionally `frames.to_vec()`s on the single-channel path (`phase_align.rs:128`) — an in-place `align_mut` avoids all of it | Low-Med | Low | EXACT |
+| F11 | Static-subcarrier selection fully sorts all subcarriers by variance (`phase_align.rs:180`) where `select_nth_unstable_by` suffices — trivial at 56 subcarriers, relevant at HE tiers (242–484) | Low | Low | **TIE** (equal-variance ties may select a different subcarrier set; pin a stable tie-break on index to stay EXACT) |
+| F12 | Engine clones each node's amplitude vector for the array coordinator every cycle: `cf.amplitude.clone()` (`engine/src/lib.rs:385`); also allocates a `Vec<Option<CalibrationId>>` per cycle (`lib.rs:293`) and `format!("{e:?}")` strings for every evidence ref (`lib.rs:337`) | Low | Low | EXACT |
+| F13 | `fuse_scored_calibrated` computes the modal calibration id in O(n²) (`multistatic.rs:404-410`) — harmless at n ≤ 15 nodes, noted for swarm-scale reuse (ADR-148) | Low | Low | EXACT |
+| F14 | **No `rayon` and no SIMD feature exists anywhere in the hot crates** (grep over `crates/*/Cargo.toml`: zero hits for rayon/simd/target-feature outside wasm-opt flags). The 12-link CIR pattern (`cir_bench.rs:4-5`) and the per-node ingest path are embarrassingly parallel **across independent links/nodes** | High (multi-link tiers) | Med | **EXACT if and only if** parallelism stays at link/node granularity with results collected in deterministic (index) order and no shared float accumulator; intra-link parallel reductions are CHANGES-FLOATS and are banned |
+| F15 | `Cir::top_k_taps` clones and fully sorts all G taps (`cir.rs:322-332`) — O(G log G) with a G-sized clone; a k-heap (the exact pattern already written in `sketch.rs:546-563`) is O(G log k) | Low | Low | TIE (equal-magnitude ordering; pin index tie-break) |
+| F16 | Core `CsiFrame` carries `Complex64` while the entire ruvsense DSP path computes in f32 (conversion at `cir.rs:525`) — 2× memory and bandwidth on every ingest for precision the pipeline immediately discards | Med (memory/bandwidth) | High (core type change ripples everywhere) | **CHANGES-FLOATS** at the boundary; defer until a major version |
+| F17 | Sketch path is already well-optimized: heap-based top-K with n ≤ k fast path (`sketch.rs:536-569`), 28-byte wire format (`sketch.rs:303`). Remaining win is build-level: `count_ones()` only lowers to POPCNT/NEON-vcnt when the target CPU enables it (see §5) | Low | Low | EXACT (integer ops) |
+
+---
+
+## 4. Memory-footprint analysis (Pi 5-class and WASM; ESP32 aggregation out of scope)
+
+**Static, per-process (from struct definitions):**
+
+| Component | Sizing source | Footprint |
+|---|---|---|
+| `CirEstimator` HT20 (Φ + Φᴴ, `Complex32`) | `cir.rs:546-547`, K=52 G=156 | 2 · 52 · 156 · 8 B ≈ **130 KB** |
+| `CirEstimator` HE20 | K=242 G=726 | ≈ **2.8 MB** |
+| `CirEstimator` HE40 | K=484 G=1452 | ≈ **11.2 MB** (halvable via F7) |
+| Tomography weight matrix | `tomography.rs:214-217`, sparse per-link (voxel,weight) pairs; default grid 8×8×4 = 256 voxels (`tomography.rs:70-73`) | tens of KB at default grid |
+| Sketch bank, 1,024 × 128-d | `sketch.rs` 1 bit/dim | 1,024 · 16 B ≈ **16 KB** (vs 512 KB float) |
+
+A Pi 5 (4–8 GB) absorbs all of this trivially. The real memory risks are dynamic:
+
+1. **Unbounded WorldGraph growth (the one genuine leak-class issue).** Every
+   `process_cycle` appends a `SemanticState` node plus a `DerivedFrom` edge
+   (`engine/src/lib.rs:346-352`), and change-points append `Event` nodes
+   (`lib.rs:422-428`). At 20 Hz that is **1.73 M nodes/day** with no eviction anywhere
+   in the engine. `snapshot_json` (`lib.rs:191-193`) then serializes the whole graph.
+   **Required:** a retention/compaction policy (ring buffer or time-windowed rollup of
+   SemanticStates). Determinism caveat: eviction changes snapshot *contents* (a product
+   decision), not float math — the per-cycle witness (`lib.rs:437-448`) is unaffected.
+2. **Per-cycle allocation churn** (F1, F3, F5, F8, F10, F12): at 20 Hz this is dozens of
+   short-lived heap allocations per cycle. On a Pi 5 this is allocator pressure and
+   cache pollution rather than RSS growth; on WASM (bump-ish dlmalloc, no MADV_FREE) it
+   inflates the linear memory high-water mark, which is never returned to the host.
+3. **WASM targets.** `wifi-densepose-wasm` is a browser binding crate (JS interop,
+   serde, chrono — `crates/wifi-densepose-wasm/Cargo.toml`) and pulls `wifi-densepose-mat`
+   optionally; it relies on `wasm-opt -O4` (`Cargo.toml` `[package.metadata.wasm-pack]`).
+   `wifi-densepose-wasm-edge` is the disciplined one: `no_std` + `libm`, its own profile
+   `opt-level = "s"`, lto, cgu=1 (`crates/wifi-densepose-wasm-edge/Cargo.toml`). Neither
+   enables `+simd128` (§5). If the CIR estimator is ever compiled to wasm-edge, HE40's
+   11.2 MB of sensing matrix alone is ~700 pages of linear memory — restrict edge WASM
+   to HT20 (130 KB) or ship F4/F7 first.
+
+---
+
+## 5. Build-profile review & recommendations
+
+Current release profile (`v2/Cargo.toml:213-218`) is already aggressive and correct:
+`opt-level = 3`, `lto = true` (fat), `codegen-units = 1`, `panic = "abort"`,
+`strip = true`; `bench` inherits release with debug symbols (`v2/Cargo.toml:225-227`).
+There is nothing wrong to fix here — the gains left are target- and feedback-driven:
+
+1. **Per-target CPU tuning (EXACT, do first).** No `target-cpu` is set anywhere. For
+   Pi 5 fleet builds: `RUSTFLAGS="-C target-cpu=cortex-a76"` — enables NEON scheduling
+   and `vcnt` for the sketch path (F17) without changing IEEE semantics. LLVM does not
+   reassociate float reductions or contract to FMA without explicit fast-math/contract
+   flags, so scalar float results stay bit-exact. **Verify with the existing proof
+   runners** (`cir_proof_runner`, `calibration_proof_runner`,
+   `signal/Cargo.toml`) as the acceptance gate — that is exactly what they exist for.
+2. **WASM SIMD.** Add `-C target-feature=+simd128` for `wifi-densepose-wasm` builds and
+   keep a non-SIMD artifact for older runtimes. Same determinism note as above; gate
+   with the proof runners compiled to wasm where feasible.
+3. **PGO: feasible and determinism-safe.** PGO changes inlining/layout, never FP
+   semantics. The repo already has ideal deterministic training workloads: the proof
+   runner binaries plus `engine_cycle` / `cir_bench`. Pipeline: `cargo pgo build` →
+   run proof runners + benches → `cargo pgo optimize`. Expect mid-single-digit to ~15%
+   on branchy paths (gate decisions, tracker lifecycle); the dense ISTA loop will see
+   little. Cost: CI complexity. Verdict: do it after F1–F12, not before.
+4. **Do not** enable `-ffast-math`-equivalents (`fadd_fast`, `core::intrinsics`,
+   `-C llvm-args=-fp-contract=fast`) anywhere in the witness path. This must be a
+   stated rule in CONTRIBUTING/ADR, not tribal knowledge.
+5. **BOLT / `opt-level` experiments are not worth it** ahead of F4; the pipeline is
+   FLOP-bound in one loop, not front-end bound.
+
+---
+
+## 6. Prioritized 90-day plan
+
+### Phase 0 — Measure (days 1–10)
+- Run and commit criterion baselines on a Pi 5 and an x86 dev box:
+  `engine_cycle`, `cir_bench` (all four tiers), `sketch_bench`, `signal_bench`,
+  `calibration_bench`. The 50 ms claim in `engine_cycle.rs:3` becomes a measured number.
+- Add a lightweight per-stage timing histogram (feature-gated, off in witness builds) at
+  the §2 stage boundaries; wire a CI perf-regression gate (±10%) on the committed
+  baselines.
+- Re-run the soak that produced `benchmark_baseline.json` and pin it as the accuracy
+  guardrail for everything below.
+
+### Phase 1 — Exact, zero-risk wins (days 10–35)
+All EXACT findings; no witness impact; each lands with proof-runner verification:
+- F5 (precompute warm-start diag/CSR in `CirEstimator::new`) — biggest exact CIR win.
+- F8 (hoist tomography gradient buffer), F6, F10, F12, F1, F2 (allocation/duplication
+  removal), F15 + F11 with pinned index tie-breaks.
+- WorldGraph retention policy (the §4.1 unbounded-growth fix) — design ADR + ring-buffer
+  implementation.
+- Expected outcome: measurable cycle-time reduction and flat memory under 24 h soak;
+  **identical witness hashes**.
+
+### Phase 2 — Determinism-managed structural wins (days 35–70)
+Each behind a feature flag, A/B'd against the legacy path (the `use_cir_gate` A/B switch
+at `multistatic.rs:103` is the template), with proof-hash regeneration as an explicit,
+witnessed release event:
+- **F4: FFT-based Φ/Φᴴ application in ISTA** — the headline item; the only route to
+  HE20/HE40 real-time and the 12-link pattern. Acceptance: cir_bench speedup ≥ 5× at
+  HE20, soak metrics within guardrail, new `expected_features.sha256` published in a
+  fresh witness bundle.
+- F9 (power-method Lipschitz in tomography) riding the same hash-regen train.
+- F3 (slice-based CIR entry point), choosing the exact-f64-intermediate variant if the
+  hash train slips.
+- F14: feature-gated `rayon` across **links/nodes only**, deterministic index-ordered
+  collection; CI must run the determinism test (`engine/src/lib.rs:535-548`
+  `cycle_is_deterministic`) with the feature on.
+
+### Phase 3 — Platform & toolchain (days 70–90)
+- Pi 5 `target-cpu=cortex-a76` fleet builds + proof-runner verification (§5.1).
+- `+simd128` WASM artifact + size budget check for wasm-edge (§5.2, §4.3).
+- PGO pilot in CI using proof runners as the training corpus (§5.3).
+- Re-baseline: new criterion numbers, refreshed witness bundle, updated this document's
+  §1 with real measured latencies.
+
+**Out of 90-day scope, flagged for the architecture backlog:** F16 (Complex64→Complex32
+in core), F7 (single-matrix Φ kernel — bundle with F4), and HE40-on-edge (blocked on
+F4+F7).
+
+---
+
+## 7. Summary
+
+The pipeline's only structural latency hazard is the dense ISTA CIR solver
+(`cir.rs:601-654` + `cir.rs:717-745`): fine at HT20, ~1.1 GFLOP worst-case per estimate
+at HE40, and slated to run per-link (×12). Everything else is allocation churn and
+duplicated work that can be removed with **bit-exact** refactors (F1–F12), plus one
+genuine memory bug-class issue: unbounded WorldGraph growth at 20 Hz
+(`engine/src/lib.rs:346-352`). The build profile is already optimal; remaining toolchain
+gains (target-cpu, wasm simd128, PGO) are determinism-safe and cheap. The determinism
+constraint is workable because the repo already owns the right tools — deterministic
+proof runners, an A/B gate pattern, and a per-cycle witness — so float-changing
+optimizations become scheduled, witnessed hash-regeneration events rather than risks.

+Research swarm output (2026-06-09) defining what a beyond-state-of-the-art
+RuView implementation is, what the current system actually delivers, and the
+validation/benchmark/optimization evidence gathered in the same session.
+
+Produced by a 5-agent hierarchical research swarm (system reviewer, SOTA

+validation pass run against the working tree.
+
+## Documents
+
+| Doc | Scope | One-line takeaway |
+|-----|-------|-------------------|
+| [00-system-review.md](00-system-review.md) | Capability audit of the current engine | Signal layer is the deepest asset (`ruvsense/` ≈14.4k lines, 310 in-module tests); the model tier is the emptiest (no trained checkpoint in-tree); the live 20 Hz path is the main integration gap |
+| [01-sota-landscape-2026.md](01-sota-landscape-2026.md) | Published SOTA per capability axis (web-verified) | Defines the beyond-SOTA bar: 12-row capability → published SOTA → RuView-today → target table; IEEE 802.11bf-2025 is ratified and moves the moat up-stack |

+## Validation results (this session, 2026-06-09)
+
+All measured on this branch (`claude/ruview-beyond-sota-xgv8aq`), Linux
+container, `cargo test --workspace --exclude wifi-densepose-desktop
+--no-default-features` (the desktop crate needs GTK system libraries absent in
+the container; this is an environment limitation, not a code failure).
+
+| Layer | Command | Result |
+|-------|---------|--------|
+| L0 unit/integration | `cargo test --workspace --exclude wifi-densepose-desktop --no-default-features` | **154 suites, 2,797 passed, 0 failed** (pre-optimization baseline; re-run post-optimization also green) |
+| L1 deterministic proof | `python archive/v1/data/proof/verify.py` | **VERDICT: PASS** — hash `f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a` (bit-exact) |
+| L2 criterion (CIR) | `cargo bench -p wifi-densepose-signal --bench cir_bench --no-default-features --features cir` | Baselines captured pre/post optimization (below) |
+
+~~Known pre-existing issue (not introduced here): `cargo check -p
+wifi-densepose-mat --no-default-features` fails standalone with 101 serde
+feature-unification errors; it builds and passes inside `--workspace` runs.~~
+**Fixed on this branch:** `pub mod api` (the only serde user) is now gated
+behind the `api` feature that owns the optional serde dependency; all feature
+combos compile.
+
+## Optimizations applied (this session)
+
+Two **exact** (bit-identical float results — summation order unchanged,
+witness chain unaffected) optimizations from the 04 roadmap's "zero-risk"
+tier were implemented and verified:
+
+1. **`cir.rs` warm-start precompute** — the diagonal Tikhonov preconditioner
+   `diag(Φ^H Φ) + λI` and its CSR matrix depend only on Φ and λ (fixed at
+   `CirEstimator::new`) but were rebuilt on every frame (O(K·G) pass + CSR
+   allocation). Moved to construction
+   (`crates/wifi-densepose-signal/src/ruvsense/cir.rs`,
+   `build_warm_start_system`).
+2. **`tomography.rs` solver hoisting** — the ISTA gradient `Vec` was
+   allocated inside the 100-iteration loop and the Frobenius Lipschitz bound
+   recomputed per `reconstruct` call; both hoisted
+   (`crates/wifi-densepose-signal/src/ruvsense/tomography.rs`).
+
+### Measured impact (criterion, paired pre/post baselines, same container)
+
+| Bench | Pre-opt | Post-opt | Change | Significant? |
+|-------|---------|----------|--------|--------------|
+| `cir_estimate/he40` | 12.34 ms | 11.86 ms | **−3.9 %** | yes (p < 0.01) |
+| `cir_multiband_3band` (30 ms group) | 30.16 ms | 29.72 ms | −1.4 % | yes (p < 0.01) |
+| `cir_multiband` (142 ms group) | 141.9 ms | 140.1 ms | −1.2 % | yes (p < 0.01) |
+| `cir_estimate/ht40` | 11.73 ms | 11.78 ms | +0.4 % | no (p = 0.28) |
+| `cir_estimate/he20` | 2.49 ms | 2.49 ms | −0.1 % | no (p = 0.85) |
+| `cir_estimate/ht20` | 2.48 ms | 2.58 ms | +3.8 % | noise — see note |
+
+Note on ht20: `cir_estimator_new/ht20` (construction, which now does strictly
+*more* work) also shows "+3 %", establishing a ≈3–4 % container noise floor;
+the ht20 estimate delta is within it. The honest summary: the warm-start
+precompute removes 1 of ~101 O(K·G) passes per frame, so the expected gain is
+≈1–4 % — consistent with what was measured. The dominant per-frame cost is
+the 100-iteration ISTA loop itself, which is exactly what the roadmap's
+flag-gated FFT-operator proposal (8–40× on the mat-vecs, requires witnessed
+hash regeneration) targets next.
+
+Correctness post-optimization: `wifi-densepose-signal` 456 tests green;
+`wifi-densepose-engine` 11/11 green including `cycle_is_deterministic` and
+`calibration_mismatch_demotes_and_witness_stable` (witness-chain stability).
+
+## Headline conclusions
+
+1. **"Beyond SOTA" is currently unfalsifiable** without a real-CSI
+   ground-truth benchmark — standing one up (per doc 03's acceptance table
+   and ADR-149's statistical protocol) is the highest-leverage next step.
+2. **The path is evolution, not rewrite**: all eight architecture pillars in
+   doc 02 land inside existing crates on the ADR-136 `Stage<I,O>`/`FrameMeta`
+   contract spine.
+3. **The biggest engineering gaps** are the live 20 Hz ingest path, a trained
+   RF encoder checkpoint, and WorldGraph retention/eviction — ahead of any
+   frontier capability work.
+4. **Determinism is the differentiator**: every optimization and new pillar
+   must preserve the witness chain; the advisory-vs-witnessed split (doc 02
+   §determinism) is the mechanism that lets frontier components in without
+   breaking it.

+> enrollment embedding + body-resonance) to be fed real measured data, which has
+> NOT been done. Measured on synthetic data, the cardiac (0.15) + respiratory
+> (0.10) channels **alone** produce a same-vs-cross-person score gap of ~0.0005
+> (test `cardiac_alone_cannot_separate_identity_matches_audit`) — i.e. identity
+> is NOT separable on those channels, exactly as expected. This status note
+> applies to §3.6 ONLY; the broader Soul Signature system remains
+> Pre-Implementation.

 Given a stored profile `P` and a query embedding `Q` derived from a live sensing
 window, the match score is computed as a weighted sum of per-channel cosine

+*RuView team, June 2026. All numbers measured; full scripts and forensics in the
+[RuView repo](https://github.com/ruvnet/RuView/tree/main/benchmarks/wiflow-std).*
+
+## The setup
+
+WiFi sensing is having a moment: a 2026 preprint ("WiFlow", arXiv 2602.08661)
+claims **97.25% pose-estimation accuracy (PCK@20) from WiFi signals alone**,
+with a tiny 2.23M-parameter model — and unlike most papers, it ships
+everything: code, trained weights, and a 360,000-sample dataset.
+
+We build WiFi sensing systems, so before adopting any external number we run
+it through a simple rule: **a claim is "CLAIMED" until we reproduce it, then
+it's "MEASURED."** Here's what happened when we tried.
+
+## Day 1: nothing works
+
+- **The code doesn't run.** The package imports a class that doesn't exist.
+  (One-line fix.)
+- **The released model scores 0.08%, not 97.25%.** The shipped checkpoint was
+  trained under a different data normalization than the shipped dataset —
+  it's a real trained model, just not *this* pipeline's model. Even letting it
+  cheat with a fitted per-keypoint correction only reaches 72%.
+- **The dataset is corrupted.** Its last 13 files contain garbage values up to
+  3.4×10³⁸ (float32's maximum). Subtle consequence: the training loop uses
+  fp16 mixed precision with no guards, so the first corrupted batch overflows
+  and **permanently poisons the model's BatchNorm statistics**. Training from
+  the public download produces NaN from epoch 1, every time.
+- The training script also crashes before its own test phase ever runs
+  (calls an undefined function), and ignores its `--data_dir` flag.
+
+At this point a less patient reader concludes "fraud." That would be wrong.
+
+## Day 1, later: actually, the science is real
+
+We repaired the artifacts — fixed the import, zeroed the 9,072 corrupted
+windows, retrained from scratch with the authors' own code and
+hyperparameters on one GPU (~50 minutes):
+
+| Metric | Published | Our retrain |
+|---|---|---|
+| PCK@20 | 97.25% | **96.1–96.6%** |
+| PCK@50 | 99.48% | 99.0–99.1% |
+| Params | 2.23M | 2,225,042 (exact) |
+
+**The claims reproduce.** What didn't survive contact was the *packaging*:
+wrong checkpoint, corrupted upload, broken glue code. This distinction —
+**artifact rot vs. bad science** — is the single most useful thing a
+reproduction can establish, and you can't establish it without actually
+running the thing.
+
+(We filed all six defects upstream with fixes:
+[issue #3](https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling/issues/3).
+And to be clear: the authors released more than 90% of papers do. That's the
+only reason this audit was possible.)
+
+## Day 2: the model is also 2.6× too big
+
+Once we could train, we asked: does the architecture need 2.23M parameters?
+
+| Variant | Params | Accuracy (PCK@20) | Size on disk |
+|---|---|---|---|
+| Original | 2,225,042 | 96.61% | 8.97 MB |
+| **Half** | **843,834** | **96.62%** ✨ | — |
+| Quarter | 338,600 | 96.05% | — |
+| **Tiny** | **56,290** | **94.11%** | **295 KB** |
+
+The half-width model **matches the original exactly** (and converges faster).
+The tiny one — 1/39th the parameters — gives up 2.5 points and runs at
+**0.66 ms per inference on a laptop CPU** (~1,500 poses/second) as a 295 KB
+ONNX file. For edge devices, that's the interesting end of the curve.
+
+Quantization footnote: the paper's "~2.2 MB int8" estimate is reachable
+(we measured 2.44–2.53 MB) but only via conv-capable toolchains — PyTorch's
+one-line dynamic quantization converts *literally nothing* on this model
+(it has no Linear layers), a trap worth knowing about.
+
+## What we took away
+
+1. **Run the artifact, not the README.** Every number in a paper is one
+   `git clone` away from being either confirmed or understood. Both outcomes
+   are valuable; only one is publishable by the original authors.
+2. **fp16 + unvalidated data = silent model death.** Mixed-precision training
+   with no NaN/inf guards doesn't fail loudly — it corrupts BatchNorm buffers
+   and ships a broken model with a green progress bar. Validate inputs, or
+   train in fp32, or guard the autocast.
+3. **Evidence-grade your own claims too.** Mid-audit, the same forensics
+   tooling caught one of *our own* published accuracy numbers resting on a
+   degenerate evaluation (a constant-output model scored with a flawed
+   metric). We retracted it the same day. The rule has to cut both ways or
+   it's marketing, not measurement.
+4. **Over-parameterization hides in SOTA tables.** Nobody publishes the
+   half-size ablation that matches their headline model. Run it yourself;
+   it's an hour of GPU time and sometimes it *is* the result.
+
+*Reproduction scripts, corruption masks, the efficiency-sweep configs, and a
+numerically parity-proven Rust port (max divergence 1.2e-7) are all in
