fix(wasm-edge): sanitize non-finite host floats at the WASM↔host frame boundary (#1102)

Closing beyond-SOTA security review of wifi-densepose-wasm-edge (ADR-040,
~70 edge modules). The two WASM↔host boundaries (lib.rs::on_frame/on_timer
and bin/ghost_hunter.rs::on_frame) read raw IEEE-754 f32 from the csi_get_*
imports with no finiteness check — the crate had zero is_finite/is_nan
guards and its clamp helpers propagate NaN. A single non-finite host value
latches NaN into long-lived per-module accumulators (EMA / Welford / phasor
sums / anomaly baselines), after which detectors fail degraded (stuck gate
state, silently-disabled checks) — silent corruption, not a crash.

Add sanitize_host_f32() (non-finite -> 0.0, core-only for no_std) applied at
every host_get_* float read: one chokepoint covering all downstream modules,
mirroring the existing M-01 negative-n_subcarriers boundary clamp. LOW /
defense-in-depth (the Tier-2 DSP firmware supplies the imports, a semi-trusted
boundary).

Pinned by boundary_tests::{sanitize_passes_finite_values_through,
sanitize_maps_non_finite_to_zero,
coherence_monitor_nan_latches_without_sanitize_but_not_with} — the last
asserts on the current CoherenceMonitor that a raw NaN frame latches the
smoothed score while the sanitized path stays finite.

Other review dimensions attested clean with evidence (see CHANGELOG): no
hot-path panics (all unwrap/expect are test-only or std-gated RVF builder),
all bounds min()-clamped, all index-by-cast const-bounded or guarded, no
leaking closures (no move||/forget/leak), no secrets.

Verified: host `cargo test --features std,medical-experimental` 672 passed /
0 failed (+3 new tests); all three wasm32-unknown-unknown release artifacts
build clean (lib default no_std/panic=abort, ghost_hunter standalone-bin,
medical-experimental); Python proof VERDICT PASS, hash unchanged.

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

+## Implementation Notes
+
+### 2026-06 — ESP32 edge vitals: person-count over-count + presence flicker (#998, #996)
+
+Two robustness bugs were fixed in the on-device edge path (`firmware/esp32-csi-node/main/edge_processing.c`, the ADR-039 packet `0xC5110002`). These touch the *boolean/count emission logic*, not the underlying CSI signal-processing math, and do **not** constitute a validated-accuracy claim — true occupancy-count and presence accuracy vs labelled ground truth remain hardware/data-gated (COM9 ESP32-S3 + labelled capture).
+
+- **#998 `n_persons` over-count (reported 4 for one person).** `update_multi_person_vitals()` divided the top-K subcarriers into `top_k_count/2` groups and marked *every* group `active`, so one body's multipath always read the full `EDGE_MAX_PERSONS`. Added an energy gate (`EDGE_PERSON_MIN_ENERGY_RATIO`), spatial dedup (`EDGE_PERSON_MIN_SC_SEP`), and a persistence debounce (`EDGE_PERSON_PERSIST_FRAMES`) via two pure functions `count_distinct_persons()` / `person_count_debounce()`.
+- **#996 presence flag flicker at ~50 cm.** Single-threshold compare on a noisy `presence_score` chattered at the boundary. Replaced with a Schmitt trigger + clear-debounce (`presence_flag_update()`, constants `EDGE_PRESENCE_HYST_RATIO` / `EDGE_PRESENCE_CLEAR_FRAMES`); `presence_score` is unchanged and still emitted for consumer-side thresholding.
+
+Both are pinned by host-buildable C99 tests in `firmware/esp32-csi-node/test/test_vitals_count_presence.c` (`make run_vitals`). The exact thresholds are documented constants pending on-device calibration against ground truth.
+
+### 2026-06 — Rust `wifi-densepose-vitals`: IIR filter NaN/inf self-heal (ADR-158 §A1)
+
+A correctness/safety review of the Rust extraction crate found a real bug parallel to the firmware robustness class above. The 2nd-order resonator `bandpass_filter` in both `breathing.rs` and `heartrate.rs` latches each output `y[n]` into its filter state (`y1`/`y2`). A single non-finite amplitude residual from a corrupt CSI frame produced a NaN `output` that was written into the state; the existing `extract()` `is_finite()` guard dropped that one sample from the history buffer **but never sanitized the poisoned filter state**, so every later output stayed NaN, was rejected too, and the sliding-window history never refilled — breathing **and** heart-rate extraction went silently dead (returning `None` forever) until `reset()`. On the alert path this is a safety-relevant denial of service (one bad frame stops vitals monitoring with no error surfaced).
+
+Fix: when `bandpass_filter` computes a non-finite `output`, it resets the IIR state to default and returns `0.0`, so the resonator self-heals on the next clean frame (the `0.0` is still dropped by the caller's finite-check, so no spurious sample enters history). Same shape as the calibration NaN bug (ADR-154 §3) — the prior hardening guarded the *history boundary* but not the *filter-state boundary*. Pinned by `breathing::tests::nan_frame_does_not_permanently_poison_filter`, `breathing::tests::inf_mid_stream_does_not_freeze_history`, and `heartrate::tests::nan_frame_does_not_permanently_poison_filter` (all FAIL pre-fix, verified by reverting). The review also de-magicked the HR physiological plausibility band into named `HR_PLAUSIBLE_MIN_BPM`/`HR_PLAUSIBLE_MAX_BPM` consts (value-identical 40/180 BPM) and added a fabricated-vital negative (`pure_noise_is_never_reported_valid` — broadband noise never yields a clinically `Valid` HR; the extractor honestly returns low-confidence `Unreliable`). Clean dimensions confirmed with evidence: flat/silent input → `None`; pure noise → low-confidence `Unreliable`, never `Valid`; harmonic-rich breathing with no cardiac component → low-confidence, not a confident false HR; out-of-band BPM rejected by the plausibility clamp.

+## 4.1 Crypto/security review notes (§2.2 witness chain — ADR-262 P2 prerequisite)
+
+Beyond-SOTA crypto+security review of the SHA-256 + Ed25519 witness chain
+(`witness.rs` / `witness_signing.rs`) and the manifest signature surface
+(`manifest.rs`), because ADR-262 P2 proposes to **reuse this exact signing
+chain**. Top priority was the sibling `wifi-densepose-engine` bug class —
+unframed boundary-to-boundary concatenation of operator-influenceable strings
+into a signed/hashed digest.
+
+- **Engine bug class ABSENT (good result, reported with byte evidence).**
+  `canonical_bytes` is `DOMAIN_TAG ‖ prev_hash[32] ‖ seq:u64-be ‖ ts:u64-be ‖
+  kind_len:u32-be ‖ kind ‖ payload_len:u32-be ‖ payload`. The two
+  variable-length operator-influenceable fields (`kind`, `payload`) are
+  **length-prefixed**; the fixed-width fields are self-delimiting → the
+  encoding is injective (no two distinct event tuples share a preimage). The
+  Ed25519 signature signs the **identical** bytes the SHA-256 chain commits to.
+  No separate unframed concatenation exists; the manifest `binary_signature`
+  is signed at build time (Makefile) over a single fixed-length `binary_sha256`
+  hex value, not in-crate.
+
+- **CHM-WIT-01 (FIXED) — domain-separation tag added.** The engine fix
+  prescribed *domain-tag + length-prefix*; length-prefix was present, the
+  domain tag was not. Added a versioned, NUL-terminated
+  `WITNESS_DOMAIN_TAG = b"cog-ha-matter/witness-event/v1\x00"` prefix so the
+  witness message can never be replayed as a message for another Ed25519
+  context that shares key infrastructure (notably the manifest signature).
+  **Witness bytes change by design** (prior on-disk hashes/signatures
+  invalidated, as with the engine fix); verified safe because no in-repo crate
+  consumes cog-ha-matter witness bytes programmatically (doc-mentions only).
+
+- **CHM-WIT-02 (HARDENED) — `verify_signature` now uses `verify_strict`.** For
+  an audit chain the signature is the attestation, so non-canonical encodings
+  and small-order keys are rejected (RFC 8032 strict), giving the "one
+  canonical signature per event" property. Not a forgery fix — the verifying
+  key is caller-pinned, never read from the event.
+
+- **Confirmed clean (with evidence):** verify-before-trust + key-pinning
+  (`verify_signature` takes the verifying key as a parameter; `read_jsonl`
+  re-derives every hash and chain-verifies); key handling (the crate never
+  generates/stores/logs/serializes a signing key — only a documented test-only
+  fixed seed; production keys come from the Seed secure store, out of scope);
+  determinism (positional bytes, deterministic Ed25519, alphabetically-locked
+  JSONL field order, sorted TXT records — no HashMap/float nondeterminism feeds
+  any digest); fail-closed parsing (structured errors, no panics; `main.rs`
+  reads no untrusted files/paths).
+
+Tests: `cog-ha-matter --no-default-features` 64 → **68**, 0 failed (CHM-WIT-01
+pinned by 4 fails-on-old tests across `witness.rs`/`witness_signing.rs`;
+CHM-WIT-02 guarded by a key-pinning test). Python deterministic proof
+unchanged (cog-ha-matter is off the signal proof path).

+## 9. Security & concurrency review (P1 core, beyond-SOTA sweep)
+
+Foundational review of the `homecore` crate — the state store + event bus +
+service/entity registries every other HOMECORE module trusts. Same rigor as
+the ADR-129/130/132/133/161 sibling reviews. **Three real fixes (one
+concurrency, two hardening), each pinned by a fails-on-old test; the bus-lag
+and lock-discipline dimensions confirmed clean with evidence.**
+
+- **HC-RACE-01 (state-set TOCTOU — lost / reordered `state_changed`, the
+  crux). FIXED.** `StateMachine::set` did `get()` (releasing the DashMap
+  shard lock) → compute the next snapshot + the no-op / `last_changed`
+  decision → `insert()` (re-acquiring the lock) → `send()`. The
+  read-modify-write was **not atomic** w.r.t. a concurrent writer on the
+  same entity, contradicting §2.1's promise that "the writer atomically
+  replaces the map entry." A writer that read a stale `old` could
+  mis-classify a genuine transition as a no-op and **drop its
+  `state_changed` event** (a missed automation trigger) or fire an event
+  whose `new_state` duplicated the previously delivered one (a spurious
+  trigger for any automation keyed on `old_state != new_state`). **Fix:**
+  hold the shard write-lock across the entire read→decide→insert→fire
+  sequence via `entry()`/`insert_entry()`; `tx.send` is non-blocking,
+  non-async, and never re-enters the map, so firing under the shard lock
+  cannot deadlock and keeps global event order in lock-step with global
+  commit order. Pinned by `concurrent_set_fires_no_duplicate_adjacent_events`
+  (4 writers toggling one entity A/B; asserts no two consecutive fired
+  events carry an identical `new_state` — impossible under correct
+  serialisation; a probe observed ~93k such duplicate-adjacent events across
+  200 trials on the racy code, zero on the fix).
+- **HC-EID-LEN-01 (unbounded `entity_id` — memory-DoS at the REST boundary).
+  FIXED.** `homecore-api/src/rest.rs` parses untrusted path segments
+  straight through `EntityId::parse`; with no length cap, an
+  otherwise-valid id (`a.` + many MB of `[a-z0-9_]`) was accepted and a
+  `POST /api/states/<giant>` would persist it into the DashMap state store
+  (permanent growth across distinct ids). **Fix:** reject ids longer than
+  `MAX_ENTITY_ID_LEN` (255, HA-compatible) up front in `parse()`, before any
+  per-char scan, with a new `EntityIdError::TooLong`; fail-closed at the
+  boundary type protects every caller. Pinned by `entity_id_length_boundary`
+  (exactly-MAX accepted, MAX+1 and a 4 MiB id rejected — fails on old code).
+- **HC-SVC-PANIC-01 (service-handler panic not isolated). HARDENED.**
+  `ServiceRegistry::call` already ran handlers outside the registry lock (no
+  `RwLock` poisoning, no blocking of other callers — clean), but a
+  panicking handler unwound through `call()` into the caller's task. **Fix:**
+  wrap the handler future in `AssertUnwindSafe` + `catch_unwind`, converting
+  a panic to `ServiceError::HandlerPanicked`; the registry stays fully
+  usable. Pinned by `panicking_handler_is_isolated_and_registry_survives`.
+
+**Dimensions confirmed clean (with evidence):**
+
+- **Event-bus bounds / lag (same class as the homecore-api WS lag-DoS).**
+  Both `StateMachine` and `EventBus` use bounded `tokio::sync::broadcast`
+  (capacity 4,096). A slow subscriber gets a recoverable `Lagged(n)`
+  (drop-oldest + re-sync); `fire_*` is non-blocking and **never waits on
+  slow receivers**, so a lagging subscriber cannot block the publisher, grow
+  the channel without bound, or take down a fast subscriber. Evidenced by
+  `slow_subscriber_does_not_block_publisher_or_kill_the_bus` (fire 3×
+  capacity at an idle subscriber; publisher unblocked, bus stays live).
+- **Lock ordering / lock-across-await (deadlock).** No code path holds two
+  of `{state DashMap, registry RwLock, service RwLock}` simultaneously, so
+  no inconsistent-ordering deadlock can exist. Every `tokio::sync::RwLock`
+  guard in `registry.rs`/`service.rs` is used in a single synchronous
+  statement and dropped before any `.await`; `call` explicitly scopes the
+  read guard out before awaiting the handler. The only guard held across a
+  send is the DashMap shard lock in `set`, across a synchronous
+  (non-await) broadcast send — safe.
+- **Panic-on-input.** No reachable `unwrap`/`expect`/index in non-test code
+  beyond the safe `send().unwrap_or(0)` and the dead-but-harmless
+  `split_once(...).unwrap_or(...)` fallbacks on already-validated ids.
+
+`cargo test -p homecore --no-default-features`: **20 → 24 passed, 0 failed**
+(+4 pins). Workspace green; Python deterministic proof unchanged
+(`f8e76f21…46f7a`, bit-exact — `homecore` is off the signal proof path).

A single condition such as `{% for i in range(5000) %}{% for j in range(5000) %}xxxx{% endfor %}{% endfor %}` rendered a **100 MB string over ~11 s on one render call** (measured) — a CPU/memory denial of service (the bfld-class "unbounded expansion"; MiniJinja's per-call `range()` 10k cap does **not** stop nested loops). **Fix:** enable MiniJinja's `fuel` feature and set a per-render budget (`set_fuel(Some(1_000_000))`) so a nested loop burns one unit per iteration — the attack now fails fast (~90 ms) with "engine ran out of fuel"; plus a 64 KiB source-length cap rejecting pathological sources before compilation. Legitimate HA templates (a few dozen instructions) are unaffected. Pinned by `nested_loop_template_is_bounded_not_unbounded_dos`, `single_huge_repeat_template_is_bounded`, `oversized_template_source_is_rejected` (all fail-on-old: unbounded render / no rejection), and `legitimate_template_still_renders_within_fuel` (no regression).
+- **HC-SEC-02 (panic-on-config DoS, MEDIUM) — FIXED.** `Action::Delay { seconds }` and `Action::WaitForTrigger { timeout_seconds }` fed the user-supplied float straight into `Duration::from_secs_f64`, which **panics** on negative, NaN, infinite, or overflowing inputs — all reachable from a crafted (or typo'd) YAML (`delay: {seconds: -1}`, `.nan`, `.inf`, `1e308`). One hostile config aborts the spawned automation run task with a panic (measured: "cannot convert float seconds to Duration: value is negative"). **Fix:** a `safe_duration_from_secs` guard that saturates instead of panicking (NaN/±inf/negative → `Duration::ZERO`, matching HA's lenient "non-positive delay = no delay"; absurdly large → clamped to ~100 years). Pinned by `delay_negative_seconds_does_not_panic`, `delay_nan_seconds_does_not_panic`, `delay_infinite_seconds_does_not_panic`, `wait_for_trigger_negative_timeout_does_not_panic`, `safe_duration_saturates_hostile_values` (incl. overflow clamp).
+
+**Dimensions confirmed clean (with evidence):**
+- **Condition bypass / fail-closed eval** — a `Condition::Template` whose render errors evaluates to `false` (`condition.rs` `Err(_) => false`), and a `Choose` branch condition that fails to deserialize is treated as **non-matching** (the branch is skipped), not silently passing (`action.rs` `ChoiceBranch::matches` `Err(_) => return false`). Both fail **closed** (do-not-run), confirmed by the existing `choose_*` tests and template-false-blocks-action behavioral test. No true-by-default-on-parse-error path found.
+- **Re-entrancy / livelock (DoS)** — run-mode machinery is bounded and tested: `Single`/`IgnoreFirst` re-entrancy guard, `Restart` cancel-and-replace, `Queued` FIFO serialization, and `max: N` semaphore cap (ADR-162; `restart_mode_cancels_prior_run`, `queued_mode_runs_sequentially_not_concurrently`, `max_two_caps_concurrency_at_two`, `single_mode_does_not_double_fire_on_rapid_triggers`). A self-triggering automation does not livelock the engine — each fire is bounded by its run-mode.
+- **Action authorization** — templates are read-only sandboxed (`states`/`state_attr`/`is_state`/`now` globals; no service-call or state-set global is exposed to template scope), so a template cannot escalate into an action. Service authorization itself is enforced at the `homecore` service-registry boundary (out of this crate's scope); no gap found in what the automation crate enforces.
+- **Panic-on-config (parse)** — `serde_yaml`/`serde_json` deserialization returns structured `AutomationError` (no `unwrap`/`expect`/index reachable from a crafted config in the eval/exec path); the only remaining panic surface was the `from_secs_f64` path fixed as HC-SEC-02.
+
+Validation: `cargo test -p homecore-automation --no-default-features` → 54 passed / 0 failed (+14 over baseline). Python deterministic proof unchanged (homecore-automation is off the signal-processing proof path).

+
+## 1. Context
+
+HOMECORE (ADR-126 through ADR-134) is the native Rust + WASM + TypeScript port of Home Assistant running as the hub on the Cognitum v0 Appliance. As of P2, the state machine ([ADR-127](ADR-127-homecore-state-machine-rust.md)), API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)), and COG runtime ([ADR-128](ADR-128-homecore-integration-plugin-system.md)) are in place. What is missing is a first-class dashboard UI that operators, integrators, and residents can use to manage the full two-tier hardware stack that HOMECORE coordinates.
+
+### 1.1 The two-tier hardware model this UI must represent
+
+This is the most important architectural constraint the UI must carry through every panel:
+
+- **Cognitum SEED** — a Pi Zero 2 W-based edge node. It has its own RVF vector store (8-dim, content-addressed, with kNN queries), Ed25519 witness chain, SHA-256 ingest audit trail, onboard environmental sensors (BME280 temperature/humidity/pressure, PIR motion, reed switch, ADS1115 4-channel ADC, vibration), 13 drift detectors, an MCP proxy (114 tools, JSON-RPC 2.0, default-deny policy), 98 HTTPS API endpoints, and epoch-based swarm sync for multi-SEED deployments. SEEDs sit close to the ESP32 sensing nodes and receive feature vectors from them at 1 Hz. Multiple SEEDs can form a peer mesh. **This is the sensing and memory tier.**
+- **Cognitum v0 Appliance** — a Pi 5 + Hailo-10H hub, running at `:9000`. It hosts the COG runtime (`/var/lib/cognitum/apps/`), the HOMECORE state machine and event bus, the calibration service, `ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`, and acts as the fleet coordinator for multi-room correlation and federated training. The Appliance is where HOMECORE runs, and it is what the dashboard user is sitting in front of. **This is the computation and orchestration tier.**
+
+SEEDs are **subordinate nodes that the Appliance supervises** — they are not peers. The UI navigation hierarchy must reflect this: the Appliance is the root, SEEDs are children, ESP32 nodes are leaves.
+
+### 1.2 What the UI is not
+
+HOMECORE-UI is **not** a re-skin of the existing Cognitum Cog Store. It is a full operational dashboard that **extends** the Cognitum platform's shell — the Cog Store, API Explorer, and Guide already exist and must remain intact, with the HOMECORE dashboard added as a first-class navigation section alongside them.
+
+---
+
+## 2. Decision
+
+Build HOMECORE-UI as a **complete** TypeScript + Rust→WASM frontend (per this ADR's §3 and the HOMECORE-127…134 family) that:
+
+1. Lives at `http://cognitum-v0:9000/homecore` (or as a dedicated nav item in the Cognitum Appliance shell).
+2. Is visually and stylistically seamless with the existing Cognitum platform — same dark theme, same design tokens, same component patterns as `https://seed.cognitum.one/store`.
+3. Drives the HOMECORE REST + WebSocket API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)) and the calibration HTTP API ([ADR-151](ADR-151-room-calibration-specialist-training.md)) for all data.
+4. Updates in real-time via the homecore `subscribe_events` WebSocket channel. **The UI must never poll for entity state.**
+
+**This is a decision to deliver the complete operational dashboard — every panel in §4.1 through §4.10, every navigation section in §5, fully wired to live data — not a design-system scaffold or a partial first cut.** A static layout shell with placeholder data is explicitly **out of scope as a deliverable**: the design system (§3) is a means to the complete UI, not an end in itself. The acceptance bar for this ADR is that an operator can drive the full two-tier stack — fleet, entities, rooms, COGs, calibration, events, audit, and settings — from the dashboard, against real APIs, with no panel left as a stub.
+
+### 2.1 `homecore-server` is the single backend-for-frontend (BFF) gateway
+
+The data the dashboard needs is spread across **three backend tiers that are not one process**: (a) `homecore-api` (`/api/*` REST + `/api/websocket`, mounted in `homecore-server`); (b) the **calibration API** (`/api/v1/*`, served by a *separate* binary — `wifi-densepose calibrate-serve` / `wifi-densepose-sensing-server`); and (c) the **SEED device tier + appliance daemons** (RVF vector store, witness chain, onboard sensors, reflex rules, COG supervisor, federation), which are physically separate HTTPS services on the SEED nodes and the appliance.
+
+The browser must talk to **exactly one origin.** Therefore `homecore-server` is promoted to the **single BFF / API gateway** for HOMECORE-UI: it serves the static assets at `/homecore`, serves `homecore-api` at `/api/*`, and **adds a new `/api/homecore/*` namespace** that proxies and aggregates the calibration API and the SEED/appliance tiers server-side. The UI only ever issues same-origin requests; cross-service auth (SEED bearer tokens, calibration tokens) is held by the gateway and **never exposed to the browser**. This collapses the CORS/multi-port problem and gives one place to enforce the long-lived-access-token auth (§4.10).
+
+### 2.2 No mock data in production
+
+The in-browser mock layer that the first UI cut shipped behind DEMO banners (§7.1, prior revision) is **demoted to a dev-only fixture** gated behind an explicit `?demo=1` / `HOMECORE_UI_DEMO=1` flag. The production build wires **every** panel to a real gateway endpoint. The full endpoint contract and the backend work each panel needs are specified in **§11**; the staged path to get there is **§12**. A panel may show an empty/typed-error state when its upstream is down, but it must never silently render fabricated data.
+
+---
+
+## 3. Design system — Cognitum platform conventions
+
+The implementor **must study `https://seed.cognitum.one/store` as the definitive design reference before writing a single line of CSS.** The existing platform's design tokens, extracted from production, are:
+
+### 3.1 Colour palette (CSS custom properties)
+
+| Token | Value | Role |
+|---|---|---|
+| `--bg` | `#0a0e1a` | page background (very dark navy) |
+| `--bg2` | `#111627` | secondary background / nav strip |
+| `--card` | `#171d30` | card / panel surface |
+| `--card-h` | `#1e2540` | card hover state |
+| `--border` | `#252d45` | all border strokes (≈0.67px, subtle) |
+| `--t1` | `#e0e4f0` | primary text (near-white) |
+| `--t2` | `#8890a8` | secondary / muted text |
+| `--t3` | `#505872` | tertiary / disabled text |
+| `--cyan` | `#4ecdc4` | primary action colour (Install buttons, live indicators, accents) |
+| `--cyan-d` | `rgba(78,205,196,0.15)` | cyan tint background for status badges |
+| `--green` | `#6bcb77` | success / online / healthy states |
+| `--green-d` | `rgba(107,203,119,0.15)` | green tint background |
+| `--amber` | `#d4a574` | warning / stale / degraded states |
+| `--amber-d` | `rgba(212,165,116,0.15)` | amber tint background |
+| `--red` | `#e06060` | error / offline / veto states |
+| `--red-d` | `rgba(224,96,96,0.15)` | red tint background |
+| `--purple` | `#a78bfa` | informational / epoch / chain indicators |
+| `--purple-d` | `rgba(167,139,250,0.15)` | purple tint background |
+| `--r` | `10px` | standard border radius on all cards and panels |
+
+### 3.2 Typography
+
+- `--font`: `'Segoe UI', system-ui, -apple-system, sans-serif` — all body and heading text.
+- `--mono`: `'Cascadia Code', 'Fira Code', Consolas, monospace` — all entity IDs, API endpoints, hex values, JSON payloads, COG binary hashes.
+
+### 3.3 Component patterns (from the live Cog Store and API Explorer)
+
+- **Cards**: `background: var(--card)`, `border: 0.67px solid var(--border)`, `border-radius: var(--r)`, `padding: 24px`.
+- **Category pills / status badges**: small `border-radius: 4–6px`, uppercase text, coloured background tint (e.g. `background: var(--cyan-d); color: var(--cyan)` for `RUNNING`; `background: var(--amber-d); color: var(--amber)` for `STALE`).
+- **Primary action buttons**: `background: var(--cyan)`, `color: var(--bg)`, no border — matching the existing "Install" button style exactly.
+- **Secondary / ghost buttons**: transparent background, `border: 1px solid var(--border)`, `color: var(--t1)` — matching the existing "Details" button style.
+- **Nav strip**: `background: var(--bg2)`, text items in `--t2`, active item highlighted in `--cyan` with a bottom underline.
+- **Featured card gradient borders**: top-edge linear gradient from `var(--cyan)` to `var(--purple)` — replicate for HOMECORE section headers.
+- **Live metric cards** (API Explorer status page): icon + large numeric value in `--cyan` or `--green`, label in `--t2` below, on a `var(--card)` background.
+- **Method badge pills** on the API Explorer (`GET` in green, `POST` in amber, `AUTH` in purple) — reuse this same pill system for COG status indicators.
+
+The implementor **must not introduce new colours, typefaces, or border radii.** Every component should feel like it was built by the same team that built the Cog Store and the API Explorer. A user navigating from the Cog Store into the HOMECORE dashboard should not notice a visual seam.
+
+---
+
+## 4. UI sections — required panels
+
+### 4.1 System Dashboard (the "home screen")
+
+The always-visible overview panel. Modelled on the API Explorer's live metric cards. All values update in real-time.
+
+- **v0 Appliance health strip** — reuse the exact metric-card pattern from `seed.cognitum.one/status`: one card each for CPU %, RAM usage, Hailo-10H inference load (% utilisation), Hailo temperature, uptime, and the running services (`ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`). Values in `--cyan`, labels in `--t2`. This strip is always at the top — it represents the machine the user is looking at.
+- **SEED Fleet overview** — a grid of SEED node cards (one per paired SEED) on the `var(--card)` surface with `var(--border)`. Each card shows: online/offline status pill (green/red), firmware version, epoch number, current vector count, last ingest timestamp, and witness-chain validity badge. A collapsed row shows the SEED's 5 onboard sensors in summary (PIR: yes/no, door: open/closed, temperature from BME280). Offline SEEDs render the entire card with a `--red-d` background tint. Clicking a SEED card navigates to the SEED Detail view (§4.2).
+- **ESP32 Node summary** — count of active ESP32 nodes per SEED, current frame rate (target: 100 Hz CSI + 1 Hz feature vectors), and a compact warning list for nodes with known issues (presence_score normalisation anomaly, stale firmware version).
+- **COG Runtime status row** — a horizontal strip of status pills for each installed COG on the v0 Appliance. Pill colours follow the existing badge convention: `--green-d`/`--green` for running, `--red-d`/`--red` for failed, `--t3`/`--t2` for stopped. COG name in `--mono`. Clicking a pill navigates to COG Management (§4.6).
+- **Event Bus activity indicator** — a small real-time sparkline showing the homecore broadcast channel event rate (events/sec). Indicate channel lag if a subscriber is falling behind the 4,096-event capacity.
+
+### 4.2 SEED Detail View (per-SEED drill-down)
+
+Accessible from the fleet grid. Full-page panel for a single SEED node, using the card + section-header pattern from the Cog Store's detail views.
+
+- **SEED identity header** — `device_id` in `--mono`, firmware version, paired status in green, USB vs WiFi connection mode. A section-header gradient border (cyan → purple, matching the featured card style) visually separates this from Appliance content.
+- **Vector Store panel** — current vector count, dimension (8), last kNN query latency, current epoch number, a small sparkline of ingest rate over the last hour, and a storage budget bar showing usage against the 100K working-set target. A "Compact now" button (`POST /api/v1/store/compact`) in ghost style. When usage exceeds 80%, the bar renders in `--amber`.
+- **Witness Chain panel** — chain length (SHA-256 entries), last verification timestamp, a one-click "Verify chain" button (`POST /api/v1/witness/verify`), and an "Export attestation bundle" button for regulated deployments. The Ed25519 custody attestation (device-bound keypair, epoch + vector count + witness head) renders here. Chain length in `--purple`, following the existing epoch/chain colour convention.
+- **Onboard Sensors panel** — live readings from all 5 sensors in individual sub-cards: BME280 (temperature °C, humidity %, pressure hPa), PIR (motion boolean with last-triggered timestamp), reed switch (open/closed with last-changed timestamp), ADS1115 (4 analog channels with configurable labels), vibration (boolean with last-triggered). These are ground-truth validators against CSI readings and are critical for diagnosing false positives in the mixture-of-specialists. Sensor values in `--cyan`; sensor names in `--t2`.
+- **Reflex Rules panel** — the 3 pre-configured rules with current state: `fragility_alarm` (threshold 0.3 → relay actuator), `drift_cutoff` (threshold 1.0), `hd_anomaly_indicator` (threshold 200 → PWM brightness). Show last-fired time for each. The `fragility_alarm` threshold is the most commonly adjusted field and should be editable inline. Rules that have recently fired render with a `--amber-d` background tint.
+- **Cognitive Analysis panel** — boundary fragility score (0.0–1.0, from Stoer-Wagner min-cut on the kNN graph) rendered as a progress bar: green below 0.3, amber 0.3–0.6, red above 0.6. High fragility (>0.3) indicates a regime change in the environment and should be visually prominent. Temporal coherence phase boundaries shown as a labelled timeline of detected environment state transitions. kNN graph rebuild cadence indicator (every 10 s).
+- **Ingest pipeline status** — which ESP32 nodes feed this SEED, the packet type each is sending (`0xC5110003` native feature vectors vs `0xC5110002` vitals fallback path — distinguished visually since native is preferred), current ingest batch size, flush interval, and bridge path topology (direct vs host-laptop hop). The bridge-hop warning (known architectural limitation) renders in `--amber` since it adds a network hop.
+
+### 4.3 SEED Fleet Map (multi-SEED topology)
+
+For deployments with more than one SEED, a topology view showing the mesh:
+
+- **Node hierarchy diagram** — v0 Appliance at root, SEEDs as second tier (grouped by room/zone), ESP32 nodes as leaves under each SEED. Lines represent active data flows. ESP-NOW mesh sync links between SEEDs shown as dashed lines. Connection health shown via line colour (green/amber/red). All labels in `--mono`.
+- **Cross-SEED event deduplication indicator** — for events that span multiple SEEDs (one fall detected by two rooms; one occupant tracked through room A → hallway → room B), show a fusion badge indicating how many SEEDs contributed to the composite event.
+- **Federation config** ([ADR-105](ADR-105-federated-csi-training.md)) — federated-learning round coordinator role (which SEED is the round coordinator), current round number, K healthy nodes selected, delta exchange status. **Model deltas only — never raw CSI** is a design invariant that must be labelled explicitly in the UI.
+
+### 4.4 Entity & State Browser
+
+The homecore state machine (`DashMap<EntityId, Arc<State>>`) is the authoritative source of truth. Every COG running on the v0 Appliance contributes entities.
+
+- **Entity list by domain** — grouped by the `domain.` prefix of `EntityId`, using collapsible section headers. The 21 entities per ESP32 node (11 raw + 10 semantic primitives from `cog-ha-matter`) are the most important set. For each entity: current state string (in `--t1`), last-changed timestamp (in `--t3`), attribute map as collapsible JSON in `--mono`, and the Context (`user_id` + `parent_id` causality chain, critical for care/audit deployments). Entity IDs always in `--mono`.
+- **SEED provenance badge** — each entity carries a small badge showing its data lineage: which ESP32 node → which SEED → which COG → homecore state machine. This trace is invaluable for debugging false positives and is a **first-class UI element, not a collapsed detail.**
+- **Domain filter + semantic search** — filter by domain prefix and, once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (homecore-recorder) lands, ruvector-backed semantic search: "when did the living room anomaly score last correlate with a door-open event?" A keyword filter across entity IDs and attribute keys ships in the initial release regardless of [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) status, given entity density; the semantic search layers on top once the recorder lands.
+- **Real-time WebSocket feed** — entity states update live via the homecore `subscribe_events` WebSocket command ([ADR-130](ADR-130-homecore-rest-websocket-api.md)). The UI must never poll. Show a broadcast-channel lag indicator; warn visually if the subscriber is falling behind the 4,096-event channel capacity.
+- **StateChanged detail panel** — clicking any entity opens a slide-over panel showing the full `StateChangedEvent`: `old_state`, `new_state`, `context.id`, `context.user_id`, and the `context.parent_id` chain rendered as a breadcrumb trail.
+
+### 4.5 RoomState / Sensing Panel
+
+Surfaces the mixture-of-specialists output from the calibration service — the highest-level per-room sensing result. Data comes from `GET /api/v1/room/state?bank=<room_id>` on the v0 Appliance.
+
+- **Per-room cards** — one card per `room_id` on the `var(--card)` surface. Each card shows live `RoomState` JSON fields as sub-rows: presence (occupied/absent chip in green/red with confidence bar), posture (standing/sitting/lying chip with confidence), breathing BPM (numeric in `--cyan` with range indicator 6–30), heart rate BPM (numeric in `--cyan` with range indicator 40–120), restlessness score (0–1 progress bar), and anomaly score (0–1 with normal/anomalous label, bar turns red above a configurable threshold).
+- **STALE warning** — when `stale: true` (the specialist bank was trained against a different baseline), render the entire room card with a `--amber-d` background tint and a prominent amber banner reading "Bank stale — baseline has changed" with a direct "Recalibrate room" link into the calibration wizard (§4.7). This is the most common real-world failure mode and **must never be subtle.**
+- **VETO indicator** — when `vetoed: true` (anomaly veto suppressed vitals/posture because the window was physically implausible), render the affected specialist slots in `--red` with a "Veto active" label. Values suppressed by veto **must not render as zeros** — they must render as explicitly withheld.
+- **Null specialist placeholders** — specialists not yet trained (`null` in the specialist bank) render as "Not trained" placeholders in `--t3` with a small "Calibrate to enable" prompt in ghost style. They are **not** errors.
+- **Confidence bars** — each specialist output has a confidence float, shown as a small inline bar (`--cyan` fill) next to the reading. Low confidence (< 0.4) renders the bar in `--amber`.
+- **Multi-SEED fusion indicator** — for rooms served by multiple SEEDs, show a small badge indicating how many SEED nodes contributed to the `MultiNodeMixture` for this room's reading.
+
+### 4.6 v0 Appliance COG Management
+
+The v0 Appliance hosts COGs at `/var/lib/cognitum/apps/`. This panel is the operational companion to the existing Cog Store (`seed.cognitum.one/store`). It must match the Cog Store's visual conventions precisely — same card layout, same category pills, same install/detail button pair — because operators will move between the two surfaces.
+
+- **Installed COGs list** — for each COG: `id` and `version` in `--mono`, architecture badge (`arm`/`hailo10` etc., category-pill pattern), status pill (running/stopped/failed/updating in green/grey/red/amber), `binary_sha256` verified badge (Ed25519 signature verification shown as a shield icon in `--green` or `--red`), and PID from the pid file. Actions: start, stop, restart (ghost style), and view `output.log` / `error.log` in a monospace drawer using `--mono`. Edit `config.json` inline with syntax highlighting.
+- **COG Store / App Registry** — browsable `app-registry.json` listing. This panel should visually mirror `seed.cognitum.one/store` as closely as possible — same featured-card hero layout, same icon + title + description + category pill + action button structure. One-click install downloads the binary from GCS, verifies `binary_sha256` + `binary_signature`, writes the manifest, and starts the COG. Show which new homecore entities will appear in the state machine after install, as a preview list before confirming.
+- **OTA Updates** — a badge count on installed COGs with available updates, matching the "Installed (N)" tab badge convention from the existing Cog Store. Show a diff panel (version change, new entities, config schema changes) before confirming the update.
+- **Hailo HEF status** — for COGs with `arch: hailo10`: loaded HEF files on the Hailo-10H, current inference throughput, and `ruvector-hailo-worker:50051` connection status. The RF Foundation Encoder ([ADR-150](ADR-150-rf-foundation-encoder.md)) and neural pose head display here once available.
+
+### 4.7 Calibration Wizard
+
+The full baseline → enroll → train → verify pipeline runs via HTTP against the v0 Appliance ([ADR-151](ADR-151-room-calibration-specialist-training.md)). This is a multi-step guided flow — not a raw API panel. Use a stepped wizard layout with a progress indicator at the top (steps 1–5 as numbered pills, active step in `--cyan`, completed in `--green`, pending in `--t3`).
+
+- **Step 1 — Select room and SEED** — enter a `room_id` name (validated against `[A-Za-z0-9_-]{1,64}`) and select which SEED(s) and ESP32 nodes serve this room from a dropdown populated from the live fleet. Show current CSI ingest health for the selected nodes inline — if frames are not arriving at the expected rate, display an amber warning **before** allowing the operator to proceed. A broken ingest pipeline will silently fail calibration.
+- **Step 2 — Baseline capture** — `POST /api/v1/calibration/start`. A large full-width animated progress bar (cyan fill) reads from `GET /api/v1/calibration/status`: frames recorded vs target, ETA in seconds, `z_median` value. If `motion_flagged` is true, overlay an amber banner: "Room must be empty — movement detected." The baseline UUID produced here is the anchor for all future STALE detection for this room — display it in `--mono` once complete so operators can record it.
+- **Step 3 — Anchor enrollment** — the 8 anchor labels in enforced order: `empty`, `stand_still`, `sit`, `lie_down`, `breathe_slow`, `breathe_normal`, `small_move`, `sleep_posture`. For each: a human-readable instruction with an illustration, a countdown timer rendered as a circular progress ring in `--cyan`, and an immediate quality-gate result (accepted in green, retry in amber with a reason string). Drive via `POST /api/v1/enroll/anchor` + `GET /api/v1/enroll/status`. After each accepted anchor, show the extracted feature values (mean, variance, breathing_score, heart_score) in a small `--mono` data row so operators can sanity-check the capture. Show overall progress as "N / 8 anchors accepted."
+- **Step 4 — Train** — a single `POST /api/v1/room/train` call. Show the 6 specialist results as a checklist: presence (threshold + occupied_var), posture (prototype count), breathing (min_score), heartbeat (min_score), restlessness (calm/active motion values), anomaly (prototype count + scale). Specialists that returned non-null render in `--green`. Null specialists (insufficient anchor data) render in `--amber` with a "Re-enroll missing anchors" prompt linking back to Step 3 for the specific missing labels.
+- **Step 5 — Verify live** — display the live `RoomState` for the just-trained room using the same per-room card layout as §4.5. Prompt the operator to stand in the room and verify presence is detected, try sitting/lying to confirm posture, and breathe normally to confirm vitals are in plausible range. A "Confirm and save" button (cyan, primary) closes the wizard; a "Something's wrong — re-enroll" button (ghost) loops back to Step 3.
+
+### 4.8 Event Bus & Automation Feed
+
+- **Live event stream panel** — a virtualized scrolling list of `SystemEvent` variants (`StateChanged`, `EntityRegistered`, `ConfigReloaded`) and notable `DomainEvent`s from the homecore Tokio broadcast channel. Each row shows: event-type pill (coloured by variant), `entity_id` in `--mono`, old state → new state arrow, timestamp, and `context.user_id`. The stream is filterable by entity domain, event type, or source SEED/COG. The filter bar uses the same search-input style as the Cog Store's search field.
+- **Context causality breadcrumb** — expanding any event row shows the full Context chain (`context.id` → `parent_id` → `grandparent_id`) as a breadcrumb trail in `--mono`. This is how automation loops become visible without any separate debugging tool.
+- **Automation builder** ([ADR-129](ADR-129-homecore-automation-engine.md) scope) — a trigger → condition → action editor on the card surface. The most important RuView-specific trigger types to support are: `state_changed` on `RoomState` entities with a threshold expression (e.g. `anomaly.value > 0.8`), SEED reflex-rule firing events (`fragility_alarm`, `hd_anomaly_indicator`), and custom `domain_event` topics. Actions include calling services in the homecore service registry and firing domain events. The condition expression editor uses `--mono`.
+
+### 4.9 Witness / Audit Log
+
+- **Unified witness timeline** — a chronological merged view of events from both tiers: the SEED's SHA-256 ingest chain (every RVF store write attested) and homecore's Ed25519 state-transition chain (biometric crossings, BFLD identity-risk elevations). Each row: `entity_id` in `--mono`, old/new state, timestamp, source SEED `device_id`, signing key fingerprint (first 8 chars in `--mono`). Pagination uses the same "Showing X–Y of Z" convention from the Cog Store's cog grid.
+- **Privacy mode banner** — a persistent top-of-panel banner showing current privacy mode: `--green-d`/green text for full-publish mode; `--amber-d`/amber text for audit-only mode (SHA-256 digests on-SEED only, no MQTT state messages). Show the per-SEED privacy mode state, since SEEDs can be individually configured. Toggling privacy mode is a high-stakes action — require an explicit "Confirm" step with a summary of what will change.
+- **Export bundle** — an "Export attestation bundle" button (ghost) that packages the SEED witness chain + homecore Ed25519 chain as a downloadable archive for regulated-deployment (care home, hotel, shared office) compliance handoff.
+
+### 4.10 Settings & Integration Config
+
+- **SEED fleet management** — add, remove, and reprovision SEEDs. Show the USB-only pairing requirement prominently (the pairing window only opens via `169.254.42.1`, not WiFi — a security invariant). Per-SEED: `device_id` in `--mono`, firmware version, bearer token status, and a "Rotate token" action (ghost) that walks the operator through the secure token rotation flow.
+- **ESP32 node provisioning** — per-node NVS config display (target IP, target port, node_id), last-seen firmware version, and a link to the provisioning script. The `node_id` → room/zone assignment is editable here and persists to the room calibration system's `room_id` mapping.
+- **MQTT / cog-ha-matter config** ([ADR-116](ADR-116-cog-ha-matter-seed.md)) — broker URL, credentials (masked), MQTT topic prefix, mDNS advertisement status (`_ruview-ha._tcp`), and a live connection indicator (green dot for connected, red for unreachable). The 21 HA-DISCO entities per node are listed here with their `via_device` assignments showing which SEED they belong to in HA's device registry.
+- **Long-lived access tokens** — for homecore-api companion-app connections (HA 2025.1 wire-compat, [ADR-130](ADR-130-homecore-rest-websocket-api.md)). Token creation, last-used timestamp, and revocation. The HA companion-app pairing QR-code flow surfaces here.
+- **Federation config** — for multi-SEED deployments: ESP-NOW mesh sync status, cross-SEED epoch alignment values, and federated-learning round settings (coordinator SEED, round cadence, Krum aggregation parameters per [ADR-105](ADR-105-federated-csi-training.md)). The design invariant **"model deltas only, never raw CSI"** must be labelled explicitly in this panel.
+
+---
+
+## 5. Navigation structure
+
+HOMECORE-UI must integrate into the existing Cognitum Appliance nav shell. The top nav should read:
+
+```
+Framework | Guide | Cog Store | HOMECORE | Status
+```
+
+— inserting **HOMECORE** as a first-class nav item between the existing "Cog Store" and "Status" entries, using the same nav-item style (text in `--t2`, active state in `--cyan` with bottom underline).
+
+Within the HOMECORE section, a left sidebar (or top sub-nav on narrow viewports) provides section navigation:
+
+```
+Dashboard | SEED Fleet | Entities | Rooms | COGs | Calibration | Events | Audit | Settings
+```
+
+The COG Store panel within HOMECORE (§4.6) links out to `seed.cognitum.one/store` for the full catalog view, ensuring the existing Cog Store remains the canonical browsing experience.
+
+---
+
+## 6. Key UX invariants
+
+These must be maintained across every panel:
+
+1. **Always make the tier origin of any data explicit.** A `RoomState` reading traces to an ESP32 node → SEED → COG → v0 Appliance state machine. The provenance badge (§4.4) must appear wherever entity states are displayed.
+2. **The `stale` and `vetoed` flags from `RoomState` and the kNN fragility score from SEED cognitive analysis are meaningful diagnostic signals** — they must never be silently hidden, styled grey-on-grey, or collapsed behind an expand toggle. They represent system health operators need to act on.
+3. **Values that are `null` because a specialist has not been trained must be visually distinct from values that are unavailable due to an error.** The distinction is operationally important: `null` means "calibrate to enable," unavailable means "investigate."
+4. **All entity IDs, hashes, API endpoints, binary signatures, device UUIDs, and JSON payloads must use `--mono` font.** This is already the convention in the API Explorer and must be consistent throughout HOMECORE-UI.
+5. **The v0 Appliance Hailo HAT is a separate subsystem from the SEED's edge compute.** Inference results tagged as Hailo-sourced (COGs with `arch: hailo10`) must be visually distinguished from results from CPU-only COGs (`arch: arm`) so operators can triage hardware-specific failures.
+
+---
+
+## 7. Scope — complete UI delivery
+
+The deliverable is the **entire** dashboard. Every panel below ships fully implemented and wired to its live data source — there is no scaffold-only milestone and no panel left as a placeholder. The table records each panel's authoritative backing API so the build can proceed in whatever order best fits the dependency graph; it is a dependency map, **not** a sequence of partial releases.
+
+| Panel | Section | Backing API / source |
+|---|---|---|
+| System Dashboard | §4.1 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) WebSocket + appliance health endpoints |
+| SEED Detail View | §4.2 | SEED HTTPS API (vector store, witness, sensors, reflex, cognitive analysis) |
+| SEED Fleet Map | §4.3 | fleet topology + federation ([ADR-105](ADR-105-federated-csi-training.md)) |
+| Entity & State Browser | §4.4 | [ADR-127](ADR-127-homecore-state-machine-rust.md) state machine via [ADR-130](ADR-130-homecore-rest-websocket-api.md) `subscribe_events`; semantic search via [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) |
+| RoomState / Sensing | §4.5 | [ADR-151](ADR-151-room-calibration-specialist-training.md) `GET /api/v1/room/state` |
+| COG Management | §4.6 | [ADR-128](ADR-128-homecore-integration-plugin-system.md) plugin runtime + [ADR-100](ADR-100-cog-packaging-specification.md) app registry |
+| Calibration Wizard | §4.7 | [ADR-151](ADR-151-room-calibration-specialist-training.md) calibration HTTP API |
+| Event Bus & Automation | §4.8 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) broadcast channel + [ADR-129](ADR-129-homecore-automation-engine.md) automation engine |
+| Witness / Audit Log | §4.9 | SEED SHA-256 ingest chain + homecore Ed25519 chain |
+| Settings & Integration | §4.10 | SEED provisioning, [ADR-116](ADR-116-cog-ha-matter-seed.md) MQTT/Matter, LLAT, federation |
+
+### 7.1 Build sequencing within the complete deliverable
+
+The complete UI depends on backing services that mature on their own timelines. Each panel is built against the **real gateway endpoint** defined in §11; where the upstream is not yet available the panel renders a typed empty/error state, **not** fabricated data (the dev-only `?demo=1` fixture of §2.2 exists for offline development only and is never the shipped behaviour). Concretely, the hard contract dependencies are: [ADR-130](ADR-130-homecore-rest-websocket-api.md) (REST + WebSocket), [ADR-127](ADR-127-homecore-state-machine-rust.md) (state machine), [ADR-151](ADR-151-room-calibration-specialist-training.md) (calibration), [ADR-128](ADR-128-homecore-integration-plugin-system.md) (plugin runtime), [ADR-129](ADR-129-homecore-automation-engine.md) (automation), [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (event history + semantic search), [ADR-116](ADR-116-cog-ha-matter-seed.md) (SEED/Matter), [ADR-069](ADR-069-cognitum-seed-csi-pipeline.md) (SEED ingest), and [ADR-105](ADR-105-federated-csi-training.md) (federation). The keyword entity filter (§4.4) ships immediately; semantic search layers on once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) lands. The exact panel→endpoint→upstream map and the new gateway code each requires are §11; the staged delivery is §12.
+
+---
+
+## 8. Consequences
+
+### 8.1 Positive
+
+- Operators, integrators, and residents get a single coherent surface for the full two-tier stack, replacing the need to SSH into SEEDs or hand-craft API calls.
+- The dashboard reuses the proven Cognitum design tokens and component patterns verbatim, so it ships visually consistent with no separate design effort and no perceptible seam between surfaces.
+- Diagnostic signals that today are invisible (`stale`/`vetoed` flags, kNN fragility, provenance lineage, channel lag) become first-class, surfacing the system's most common real-world failure modes directly to operators.
+
+### 8.2 Negative / risks
+
+- The UI hard-depends on the wire-compat guarantees of ADR-130 and the calibration contract of ADR-151; schema drift in either breaks panels silently. Integration tests against every backing contract in §7 are required.
+- Committing to the complete UI in one deliverable is a larger up-front effort and couples the UI's readiness to the maturity of multiple backing services (§7.1, §11). The mitigation is the BFF gateway (§2.1): each panel targets one same-origin endpoint, and the gateway absorbs upstream churn behind a stable contract.
+- Promoting `homecore-server` to a gateway means it now **proxies cross-tier traffic** (calibration API, SEED HTTPS, appliance daemons). This adds a network hop, a place for upstream timeouts/partial failures to surface, and a server-side store of SEED bearer tokens that must be protected (§11.10). Each proxied route needs an explicit timeout + typed error mapping so one slow SEED cannot stall the dashboard.
+- Several panels depend on data that only exists on **real hardware or new daemons** (SEED device tier, appliance host metrics, COG supervisor). Until those upstreams exist the corresponding gateway routes return `503 upstream_unavailable`; this is honest but means the dashboard is only as "live" as the tiers behind it (§11 classifies every endpoint by what it depends on).
+- Faithfully mirroring `seed.cognitum.one/store` couples HOMECORE-UI to the external Cog Store's evolving design; token drift there must be tracked and re-synced.
+- The two-tier mental model (Appliance root, SEED children, ESP32 leaves) must be enforced consistently; any panel that flattens or peers the tiers undermines the core architectural constraint.

+
+## 10. Implementation status
+
+Implemented as a zero-dependency, no-build-step vanilla TS/JS + CSS frontend served by `homecore-server` at `/homecore` (the `rufield-viewer` "Axum + vanilla-JS" pattern). The complete deliverable per §2/§7 — all ten panels, fully rendered, wired to live data where the backing service exists and to a contract-conformant DEMO-flagged mock layer (§7.1) where it does not.
+
+**Location:** `v2/crates/homecore-server/ui/` — `css/tokens.css` (the §3.1 palette, verbatim) + `css/app.css` (§3.3 components); `js/{ui,api,ws,mock,app}.js` (shared helpers, REST client, `subscribe_events` WS client, mock layer, shell+router); `js/panels/*.js` (one module per §4 panel). Mounted via `tower-http` `ServeDir` in `homecore-server::build_app`, gated by `--ui-dir`/`HOMECORE_UI_DIR`.
+
+**Verification:**
+- **Rust** — `#[cfg(test)] mod ui_tests` in `homecore-server/src/main.rs`: 5 integration tests (`tower::oneshot`) covering index, design tokens, all ten panel modules served, API coexistence, and mount-disable. *Written but not compiled in the authoring environment (no Rust toolchain present); run `cargo test -p homecore-server` on a Rust host before merge.*
+- **Frontend** — `ui/` test suite under plain `node` (no npm install): `npm test` → import/export graph verifier (15 modules) + render-smoke (executes every panel against a DOM shim; 21 checks) + interaction suite (live WS patch, ws.js handshake/parse, calibration contract; 3 checks). **24/24 green.**
+- **Benchmark** — `npm run bench`: total bundle **136.8 KB** uncompressed (**~37× smaller** than HA's ~5 MB Lit bundle, the ADR-126 §1.1 foil); slowest panel **1.5 ms/cold-render**.
+
+**Honest scope — current vs. target.** *Earlier cut:* the front-end was complete but only §4.4 Entities was wired to a real backend; the rest rendered from an in-browser mock. *This revision implements the §11 wiring:*
+
+- **Front-end (§11.11) — DONE and verified.** `api.js` rewritten: all data accessors are async and call the §11.2 gateway routes; the mock layer is demoted to a dev-only fixture reachable **only** under `?demo=1` / `HOMECORE_UI_DEMO` (§2.2); every panel `await`s and renders a typed empty/error state on failure (no mock fallback in production). All ten panels converted (3 by hand, 7 via parallel agents). Verified under Node: 5 test files green — import graph, boot, render-smoke (22), interaction (3), **and a new prod-errors suite (13) that runs with demo OFF + gateway unreachable and asserts every panel renders an error state, never mock, never throws** (it caught and fixed a real unhandled-rejection in the events panel).
+- **Gateway (§11.1–§11.6) — IMPLEMENTED, COMPILED, TESTED, RUN.** New `homecore-server/src/gateway.rs` (+`reqwest` dep, +CLI/env flags `--calibration-url`/`--calibration-token`/`--apps-dir`/`--gateway-timeout-ms`, merged into `build_app` via `gateway_router`). Real handlers: `/api/cal/*` reverse-proxy (W2), `GET /api/homecore/rooms` with the §11.3 RoomState adapter (W2), `GET /api/homecore/cogs` supervisor over the apps dir (W4), `GET /api/homecore/appliance` from `/proc` + port probes (W6). SEED-device/appliance-daemon routes (seeds, federation, witness, privacy, settings, automations, events-history, hailo, tokens — W3/W5) return a typed `503 upstream_unavailable` per §11.2. **Verified on Rust 1.89: `cargo test -p homecore-server --no-default-features` = 12/12 pass** (6 gateway + 6 UI mount). **Run live:** `GET /api/homecore/appliance` returns real `/proc` metrics + TCP service probes; unauth → `401`; `cogs` → `[]` with no apps dir; SEED-tier → typed `503`; and against a mock calibration upstream the `/api/cal/*` proxy passes through (`200`) and `GET /api/homecore/rooms` correctly adapts `RoomState` to the UI shape (`breathing`→`breathing_bpm`, `heartbeat:null`→`heart_bpm:null`, injected `anomaly.threshold`/`room_id`, `stale` passthrough). **Live testing caught + fixed one real bug** — a double-`v1` path in the `/api/cal/*` proxy URL.
+
+The endpoint-by-endpoint contract is **§11**; the staged plan and which endpoints depend on real SEED/appliance hardware vs. pure software is **§12**.
+
+---
+
+## 11. Backend wiring — making every panel real
+
+This section is the authoritative contract for full functionality. It removes the mock layer from the production path (§2.2) by routing every panel through the `homecore-server` BFF gateway (§2.1). Each endpoint is classified by what it depends on:
+
+- **EXISTS** — backend code already in this repo; gateway only proxies/adapts.
+- **NEW-GW** — pure software the gateway itself implements (filesystem, `/proc`, process control, recorder query) — no new external service.
+- **NEW-API** — a small HTTP wrapper to add to an existing in-repo crate (`homecore-api`, `homecore-automation`).
+- **SEED-DEV** — depends on a SEED node's on-device HTTPS API (separate hardware/firmware).
+- **APPLIANCE** — depends on an appliance daemon / accelerator stat source.
+
+### 11.1 Gateway shape
+
+`homecore-server` already mounts `homecore-api` at `/api/*` and the UI at `/homecore`. It gains a new **`/api/homecore/*`** namespace (the dashboard-specific aggregation surface) plus a **`/api/cal/*`** reverse-proxy to the calibration service. The browser issues only same-origin requests; the gateway fans out server-side, holding all upstream credentials (§11.10). Every proxied route has an explicit timeout and maps upstream failure to a typed body (`503 upstream_unavailable`, `504 upstream_timeout`) so one slow tier never stalls the dashboard.
+
+### 11.2 Master endpoint contract (panel → gateway route → upstream → status)

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

+## 3a. Security review (2026-06, post-ADR-154–159 sweep)
+
+A beyond-SOTA security review of `homecore-recorder` covered SQL injection, retention/purge
+correctness, fail-closed write integrity, semantic-store NaN poisoning, and PII exposure.
+
+**Confirmed clean (with evidence):**
+
+- **SQL injection — clean.** Every query in `db.rs` uses bound `?` parameters; no user- or
+  entity-influenceable value is interpolated into SQL via `format!`/concatenation. The only
+  `format!` builds the `LIKE` *pattern* string, which is itself **bound** as a parameter with
+  `ESCAPE '\\'` and `% _ \` escaping — so a metacharacter payload is matched literally. Pinned
+  by `malicious_entity_id_is_stored_literally_not_executed` (a `'; DROP TABLE states; --` state
+  value leaves the table intact and round-trips verbatim) and
+  `like_metacharacters_in_query_are_literal_not_wildcards`.
+- **NaN-index poisoning — structurally impossible.** Embeddings are SHA-256 → `i32` →
+  `f32`; an `i32`→`f32` cast is always finite (never NaN/Inf), and an all-zero-digest is
+  guarded by the `norm > 1e-10` check. Empty-index search, empty-string query, and `k=0` were
+  probed and all return `Ok(0)` with no panic. (Unlike the calibration/vitals/geo paths, no raw
+  sensor float ever reaches the index.)
+- **Fail-closed writes.** A removal event returns `Ok(None)`; semantic-index failure is logged,
+  not propagated, so it never blocks the durable SQLite write; `EntityId` parse failure falls
+  back to a sentinel rather than panicking.
+
+**Fixed (real bounding bugs):**
+
+- **Memory-DoS — `get_state_history` was unbounded.** No `LIMIT`, so a wide time window over a
+  high-frequency entity loaded an unbounded row set into memory. Now capped at
+  `MAX_HISTORY_ROWS` (1,000,000); sibling search paths were already `k`-bounded.
+- **Disk-DoS / documented-but-missing `purge`.** The README advertised `Recorder::purge`, but
+  no retention path existed → unbounded disk growth. Added a **transactional** `purge(older_than)`
+  with an **exclusive** cutoff (idempotent, no off-by-one) that deletes old `states`/`events` and
+  GCs orphaned `state_attributes` blobs (dedup-shared blobs kept until their last referrer is gone).
+
+`homecore-recorder` tests: 19 → 25 (`--no-default-features`) / 25 → 31 (`--features ruvector`),
+0 failed. Python deterministic proof unchanged (recorder is off the signal proof path).

+## 6. Security review (beyond-SOTA, untrusted-input → action path)
+
+A focused security review of the Assist pipeline — `utterance → recognizer →
+intent → handler → action`, plus `RufloRunner` — treating the utterance as
+untrusted input (voice transcripts, the WebSocket `assist` command). This
+surface was not covered by the ADR-154–159 sweep.
+
+### 6.1 Finding fixed — HC-ASSIST-01 (unbounded-utterance DoS, LOW)
+
+Both `RegexIntentRecognizer::recognize` and the semantic `recognize_scored`
+accepted utterances of **unbounded length** and ran `to_lowercase()` (a full
+clone) + a per-registered-pattern scan (and, in the semantic path, full
+tokenisation + feature-hash embedding) before any bound — an allocation/CPU
+amplification on attacker-controlled input. The `regex` crate is **linear-time**
+(RE2-style finite automaton, no catastrophic backtracking), so this was a
+throughput/memory DoS, not a hang.
+
+**Fix:** `MAX_UTTERANCE_BYTES = 4096` (far above any real spoken command),
+checked at **both** recognizer boundaries *before* any allocation/scan. An
+over-length utterance **fails closed** to `Ok(None)` — no intent, no action,
+identical to an unrecognised phrase — so it can never be coerced into firing a
+handler. Pinned by `over_length_utterance_fails_closed` (an over-length
+utterance that *contains* a valid command resolves to `None`, which would have
+matched on the old code) and `over_length_utterance_fails_closed_semantic`.
+
+### 6.2 Dimensions confirmed clean (with evidence)
+
+- **Command / argument injection — NO SUBPROCESS SURFACE.** The `RufloRunner`
+  has exactly two impls: `NoopRunner` (no process) and `LocalRunner` (runs the
+  local recognizer, no process). There is **no** `std::process` / `tokio::process`
+  / `Command` / process `.spawn()` anywhere in the crate — the trait `spawn` is
+  only a `started: bool` lifecycle flag — and `RufloRunnerOpts.{script_path,env}`
+  are **inert data, never consumed**. The live `node ruflo-agent.js` runner is
+  genuinely data-gated/future (P2). Defence-in-depth: the `entity_id` capture
+  class `[a-z_][a-z0-9_ .]*` **excludes every shell/SQL metacharacter**, so even
+  when an injection-shaped utterance resolves (the regex is not exact-anchored),
+  the captured slot is a clean token — sanitisation by construction. Pins:
+  `shell_metachars_never_survive_into_a_resolved_slot`,
+  `runner_opts_are_inert_no_process_spawned`,
+  `pipeline_injection_shaped_utterance_carries_no_metachars_to_service`.
+- **ReDoS — STRUCTURALLY IMPOSSIBLE.** `regex 1.12.3` (no `fancy-regex` in the
+  dependency tree) is linear-time; a classic `(a+)+$` shape on adversarial input
+  completes in bounded time. Pin:
+  `pathological_backtracking_pattern_completes_in_bounded_time`. Patterns are
+  operator-registered, not user-supplied, in any case.
+- **NaN-poisoning — EMBEDDINGS STRUCTURALLY FINITE.** The embedding path takes
+  only `&str` and produces values via FNV feature-hashing + a guarded L2
+  normalise (`norm > 1e-12`); no external float input, no unguarded division, so
+  a crafted utterance cannot inject NaN/Inf to poison the cosine k-NN. Cosine
+  against the zero vector is a finite `0.0`; an empty index `max_by` returns
+  `None` (no panic); the NaN-safe `partial_cmp().unwrap_or(Equal)` is already in
+  place. Pins: `embeddings_are_structurally_finite`,
+  `cosine_with_zero_vector_is_finite_not_nan`,
+  `empty_utterance_against_empty_index_no_panic_no_match`.
+- **Intent confusion / fail-closed.** An unrecognised utterance → `not_understood()`
+  (no service call); a recognised intent with no registered handler →
+  `not_understood()`; semantic below-threshold / empty-index → regex fallback.
+  No default high-privilege intent, no fail-open path.
+- **Panic-on-input.** No `unwrap`/`expect`/index reachable from a crafted
+  utterance; the one `exemplars[id]` index uses an `id` from `enumerate()` over
+  the append-only exemplar `Vec` (no remove API), so it is always in bounds.

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

+## Privacy Monotonicity Review (2026-06-14) — confirmed clean
+
+A beyond-SOTA security review of the governed-trust cycle
+(`wifi-densepose-engine::StreamingEngine::process_cycle_calibrated`) examined
+the privacy-demotion path this ADR governs. **The monotonicity invariant holds:
+demotion only ever makes the emitted class more restrictive, never less.**
+
+Verification (no behaviour change, the result is a clean bill with evidence):
+
+- Each cycle computes `effective_class` fresh from the active mode's
+  `target_class()` (the floor) and applies at most a **single-step** demotion
+  (`demote_one`, clamped at `Restricted`). There is no cross-cycle state that
+  could let a permissive class overwrite a restrictive one.
+- A forced contradiction (calibration mismatch / array-geometry insufficiency /
+  mesh partition risk, ADR-032) raises the class byte; a clean cycle emits
+  exactly the base class.
+- Pinned by `forced_contradiction_never_relaxes_class`, a property test over
+  **all five** `PrivacyMode`s asserting `effective_class.as_u8() >=
+  base_class.as_u8()` (strictly greater unless already clamped at `Restricted`)
+  under a forced contradiction, and `== base` on a clean cycle.
+
+Fail-closed boundaries were also pinned: an empty cycle errors (no degenerate
+over-permissive output, `empty_cycle_fails_closed`) and the single-node boundary
+is characterized as a valid non-demoting mode (`single_node_cycle_is_well_formed`).
+
+The related witness domain-separation fix from the same review is recorded in
+ADR-137 (the witness folds `effective_class`, so the demotion is auditable).

+
+Beyond-SOTA privacy+security review of `wifi-densepose-bfld` (the crate was not in the ADR-154–159 sweep). Two real bugs fixed (each pinned by a fails-on-old test), several dimensions confirmed clean.
+

+
+| # | Severity | Site | Issue | Fix | Pinned by |
+|---|----------|------|-------|-----|-----------|
+| 1 | **privacy-bypass (HIGH)** | `pipeline.rs::process_to_frame` | The documented wire-bytes production path stamped the frame header with the active `PrivacyClass` but serialized the caller's `BfldPayload` **unchanged** via `BfldFrame::from_payload` — never routing through `PrivacyGate::demote`. A frame labeled `Anonymous`(2)/`Restricted`(3) carried the full `compressed_angle_matrix` (identity surface) + amplitude/phase + `csi_delta`. A `NetworkSink` accepts class ≥ `Derived`(1), so the identity surface could cross the node boundary despite the restrictive class byte — the byte lied about content. | Apply `PrivacyGate::demote(frame, active_class)` after construction: a same-class transition that strips the sections the class forbids; `Raw`/`Derived` keep the full payload. | `tests/pipeline_to_frame.rs::process_to_frame_at_anonymous_strips_identity_leaky_sections`, `…_in_privacy_mode_strips_amplitude_and_phase` (both FAILED pre-fix); `…_at_derived_preserves_full_payload` (over-strip guard) |
+| 2 | **PII/injection (MEDIUM)** | `mqtt_topics.rs::render_events` | `zone_activity` payload built as `format!("\"{zone}\"")` with no JSON escaping (while `ha_discovery.rs` already escapes). A zone name with `"`/`\` produced malformed/injectable JSON on the HA state topic. | `json_string_literal()` escaper mirroring `ha_discovery::push_str_field`. Value-identical for normal zone names. | `tests/mqtt_topic_routing.rs::zone_payload_escapes_json_metacharacters` (FAILED pre-fix) |
+
+### Dimensions confirmed clean (with evidence)

+- **Event-field privacy gating** — `BfldEvent::apply_privacy_gating` nulls `identity_risk_score` + `rf_signature_hash` at `Restricted`, and `serde(skip_serializing_if = "Option::is_none")` omits them entirely. `render_events`/`render_discovery_payloads` refuse class < `Anonymous` (stricter than the `sink.rs` `NetworkKind` `MIN_CLASS = Derived` — defense in depth toward less leakage). Covered by `event_privacy_gating.rs`, `mqtt_topic_routing.rs`, `ha_discovery.rs`.
+- **Witness/hash framing (the engine `witness_of` bug class)** — CLEAN. `SignatureHasher::compute` prefixes a **fixed 4-byte** `day_epoch` then a **fixed-width canonical-f32** feature block (`IdentityFeatures`: Embedding = `EMBEDDING_DIM*4`, RiskFactors = 16 B). `PrivacyAttestationProof::compute` hashes a fixed 32-byte `prev_hash` + three fixed 1-byte values. No variable-length operator-influenceable string is concatenated into any digest — no length-prefix-framing collision is possible.
+- **Fail-closed** — `payload.rs::from_bytes` rejects truncated/overflowing/trailing-byte sections (`checked_add`, bounds checks); `frame.rs::from_bytes` validates magic/version/length/CRC; `PrivacyClass::try_from` rejects unknown bytes; `identity_risk::score` maps NaN/degenerate factors → 0.0 (privacy-conservative). The `from_score(NaN) → Accept` choice is a documented, deliberate publish-aggregate-only fallback (NaN never reaches it from `score()`); risk-driven NaN cannot leak identity because identity gating is class-byte-driven, not risk-driven.

+### Observation (not a bug)
+
+The ADR-141 control plane (`PrivacyMode`/`PrivacyModeRegistry`) is **not yet wired into the emit path** — the emitter/pipeline enforce the raw `PrivacyClass` directly; the registry is exported + unit-tested but advisory. This matches the "Integration glue — not yet on the live path" status above. The class-byte enforcement (emitter + event + renderers + the now-fixed `process_to_frame`) is the live guarantee. Wiring the registry is the documented next step.

+### 6.1 Correctness + security review (2026-06-14)
+
+Beyond-SOTA correctness+security review of `wifi-densepose-calibration` (this
+ADR's pipeline), un-covered by the ADR-154–159 sweep.
+
+**Finding (FIXED) — NaN-poisoning of the feature path (numerical / fail-closed).**
+`Features::from_series` — the carrier for both live inference and training-anchor
+extraction — computed `mean`/`variance`/`motion` over the raw scalar series with
+no non-finite guard. A single `NaN`/`±inf` sample (corrupt CSI frame) yielded
+`mean=NaN, variance=NaN` and an all-`NaN` prototype embedding. Persisted into a
+`PresenceSpecialist::threshold`/`empty_mean` at train time, the `NaN` **silently
+disabled presence detection** for the bank's lifetime (every `>` / `|·|`
+comparison against `NaN` is false → always reads *absent*, confidence 0), with no
+error — and an asymmetry against the rigorously NaN-guarded `geometry_embedding`.
+Fixed at the production boundary: non-finite samples are dropped (a corrupt frame
+counts as no frame), an all-non-finite series degrades to `Features::ZERO` like
+the empty series. Value-identical for all-finite input (full-loop + extract tests
+unchanged); pinned by `non_finite_samples_do_not_poison_features` and
+`all_non_finite_series_is_zero` (both fail on the old code).
+
+**Clean dimensions (evidence, no invented issues).**
+- *File/path handling:* the crate performs **zero** file/path I/O (no
+  `std::fs`/`Path`/`File`/`read`/`write` in `src/`; only in-memory `serde_json`).
+  Path-traversal / unbounded-read / artifact-path handling live entirely in the
+  `wifi-densepose-cli` consumer (`room.rs`), outside this crate's boundary.
+- *Untrusted-load:* `SpecialistBank::from_json` shape-validates via serde
+  (malformed → `CalibrationError::Serde`); banks are local-first (invariant B),
+  never network-received. A well-formed bank with adversarial numerics is trusted
+  as-is — acceptable under the local-first threat model; a validate-on-load
+  defense-in-depth pass is a possible future hardening, not a present bug.
+- *Receipt/hash integrity:* the crate emits no hash/receipt/witness/signature, so
+  the unframed-concatenation bug class (cf. the engine `witness_of` fix) is
+  structurally absent.
+- *Other numerical paths:* `geometry_embedding` sanitizes every input and sweeps
+  to finite; presence/restlessness/anomaly divisions are `.max(1e-3)`-guarded;
+  `autocorr_dominant` guards `r0`, short signals, and empty bands; `train` rejects
+  empty anchors; anomaly requires ≥2 anchors.
+
+De-magicked the bare specialist threshold literals (breathing/heartbeat default
+min-scores, anomaly outlier-spread multiple + label cutoff) into named documented
+consts, value-identical, pinned by const-equality tests. Tests
+**58→62 unit + 1 integration, 0 failed**; Python deterministic proof unchanged
+(off the signal proof path).

+
+Mirroring the ADR-154 M3 cleanup discipline, M2 closed the **host-verifiable (non-tch) subset** of the §8 backlog in `wifi-densepose-train` (+ the pure-Rust `rf_encoder.rs`/`densepose.rs` in `wifi-densepose-nn` that the §3/§4 items named). Everything behind `#[cfg(feature = "tch-backend")]` (`metrics.rs`, `model.rs`, `losses.rs`, `proof.rs`, `trainer.rs`, `wiflow_std/{layers,model}.rs`) is **out of host-verifiable scope** — it cannot be compiled/verified without libtorch and stays genuinely deferred (not dropped).
+
+**PROOF discipline held:** every de-magicked constant is pinned `== prior literal` by a `*_consts_unchanged_from_literals` test; every boundary test characterizes CURRENT behaviour; no operating-value or behaviour change; the Python proof stays bit-exact at `f8e76f21…46f7a` (the metrics path is off the signal proof path — asserted, not assumed). A smaller-but-true count was reported rather than inventing 40 fixes.

+## Addendum — `homecore-api` follow-up security review (beyond-SOTA pass)
+
+A later network-facing review of `homecore-api` (the remote REST + WS attack
+surface) — independent of the ADR-154–159 sweep — found and fixed two real
+issues the original M7 pass (which focused on the WS auth bypass HC-WS-01, the
+reply-theater HC-WS-02, and the bin token provisioning HC-WS-08) did not catch.
+Both are LOW severity and reported at true severity.
+
+### HC-API-AUTH-01 — `GET /api/` was unauthenticated (FIXED)
+
+`rest::api_root` took no headers and unconditionally returned
+`200 {"message":"API running."}`, while every sibling route gates on
+`BearerAuth::from_headers`. HA's `APIStatusView` inherits `requires_auth = True`,
+so `/api/` must return **401** for a missing/wrong bearer. HA clients use the
+status route as a token-validation probe; a 200 told a bad-token client its
+token was valid and let an unauthenticated party confirm a live endpoint.
+LOW severity (the body is a static string; no entity/state data leaks).
+
+**Fix:** `api_root(headers, State)` now validates the bearer like `get_config`.
+**Pinned by** (fail-on-old, `tests/server_bin_auth.rs`):
+`api_root_rejects_missing_bearer`, `api_root_rejects_wrong_bearer` (both 200→401),
+guarded by `api_root_accepts_correct_bearer` (still 200 with a valid token).
+
+### HC-WS-LAG-01 — `subscribe_events` killed the stream on a broadcast lag (FIXED)
+
+The per-subscription task matched `Err(_) => break` on both broadcast
+`recv()` arms. `RecvError::Lagged(n)` (a slow consumer falling
+>`EVENT_CHANNEL_CAPACITY` = 4,096 events behind) is **recoverable** — the bus
+doc says "Lagged receivers must re-sync" and HA keeps the subscription alive
+across a lag. The old code treated the first lag as fatal, so after an event
+burst the client's stream went permanently silent with no error frame — a
+self-inflicted event-delivery DoS under load.
+
+**Fix:** `Lagged(_) => continue` (skip the dropped window, re-sync),
+`Closed => break`, on both the system and domain arms of the `select!`.
+**Pinned by** `subscription_survives_broadcast_lag` (`tests/ws_handshake.rs`):
+subscribes to a filtered event type, floods 6,000 unrelated events past the
+4,096 capacity to force a `Lagged`, then asserts a subsequent subscribed event
+is still delivered (old code: 5s-timeout panic).
+
+### Dimensions confirmed clean (with evidence)
+
+- **AuthN/AuthZ** — all 7 other REST handlers gate on `BearerAuth::from_headers`
+  → `LongLivedTokenStore::is_valid` before any work; the WS handshake validates
+  the `auth` token against the same store before the command loop, and
+  privileged commands are unreachable pre-`auth_ok`. Token compare is
+  `HashSet::contains` (content-independent timing — not the byte-`==` oracle of
+  ADR-157 §B4), so no timing-oracle finding. No route skips the gate; no
+  result-ignored check; no default/empty token accepted.

+- **CORS** — explicit allowlist with `allow_credentials(false)` (HC-05),
+  not `permissive()`.

+# ADR-172: `wifi-densepose-cli` + `wifi-densepose-core` CSI-Deserialiser Security Review
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — clean-with-evidence, 4 regression pins added |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **CSI-DESERIALISER-HARDENING** |
+| **Supersedes / amends** | none (records review; references ADR-127 §9 for the `core` portion, ADR-136 for the pre-existing DoS ACs) |
+
+## Context
+
+The beyond-SOTA security sweep (branch `feat/v2-beyond-sota-sweep`) reviewed each
+`v2/` crate for real, reproducible defects. Two crates had no prior dedicated
+security ADR:
+
+- **`wifi-densepose-core`** — the dependency root for all 12 downstream crates
+  (types, traits, error types, CSI frame primitives). A defect here is a
+  force-multiplier: every consumer inherits it.
+- **`wifi-densepose-cli`** — the user-facing entrypoint
+  (`calibrate`/`calibrate-serve`/`enroll`/`train-room`/`room-watch` + MAT-gated),
+  which parses untrusted UDP CSI packets and operator-supplied paths.
+
+A **specific hypothesis** motivated the core review. Three earlier reviews in
+this campaign found a systemic **NaN-state-poisoning bug class** in crates that
+depend on core (`wifi-densepose-calibration`, `-vitals`, `-geo`): a non-finite
+(NaN/Inf) input latched into persistent filter/accumulator state (IIR `y1/y2`,
+running mean, Welford/von-Mises accumulator, voxel grid) → silent **permanent**
+feature failure. The load-bearing question for this review: **does that bug class
+originate in a shared `wifi-densepose-core` primitive** (making the right fix a
+single root fix), or was it independently re-implemented in each downstream
+crate (making the three existing local fixes complete)?
+
+## Decision
+
+Record the review outcome and lock in the existing DoS guards with regression
+tests. **No production code is changed** — both crates were already hardened
+(ADR-136 acceptance criteria + `sanitize_room_id`); the gap was *untested*
+guards, which a future refactor could silently remove.
+
+### Load-bearing question — VERDICT: **NO** (the NaN class does not live in core)
+
+`wifi-densepose-core` exposes **no stateful accumulator of any kind** — no
+Welford/running-mean, no von-Mises/circular-mean, no IIR/biquad filter state, no
+voxel grid.
+
+- **MEASURED:** `grep` over `core/src` for
+  `welford|von_mises|biquad|y1|y2|running_mean|accumulat|voxel|self.*+=` matched
+  only the `InvalidState` *error* enum variant, "reset state" doc comments, and a
+  test-only LCG — **zero** stateful logic. The only float math in core is
+  construction-time projection (`CsiFrame::new` → amplitude/phase via `mapv`) and
+  pure stateless `utils` functions; nothing persists across frames.
+- **Corroboration:** `wifi-densepose-calibration::Features::from_series`
+  (`extract.rs:103–133`) already filters non-finite samples → `Features::ZERO`.
+  The downstream fixes are independently re-implemented, confirming each crate
+  rolls its own accumulator and each local fix is correct and complete. **A fix
+  in core would be a no-op (there is nothing to fix).**
+
+Consequence: the NaN-state-poisoning class is a *downstream-local* pattern, not a
+core-rooted defect. No hidden fourth instance exists in the shared primitive.
+
+### Findings (all pins — guards already present, now tested)
+
+| # | Location | Guard (pre-existing) | Regression pin | Evidence (MEASURED) |
+|---|----------|----------------------|----------------|---------------------|
+| 1 | `core` `types.rs:801` `from_canonical_bytes` | `saturating_mul` shape-vs-length check before `Vec::with_capacity(rows*cols)` | `canonical_decode_oversized_shape_is_bounded_not_allocated` | With guard removed: **panics `capacity overflow` at `types.rs:801`**; with guard: passes |
+| 2 | `core` `types.rs` decoder | typed `CanonicalDecodeError`, never panics | `canonical_decode_never_panics_on_arbitrary_bytes` (fuzz sweep) | panic-free on arbitrary bytes |
+| 3 | `cli` `calibrate.rs:276–291` | length check `buf.len() < 20 + n_pairs*2` before `Array2::zeros(n_antennas*n_subcarriers)` | `test_parse_csi_packet_oversized_claim_is_rejected_not_allocated` | 255×65535 claim in a 2 KB packet → `None` (no allocation) |
+| 4 | `cli` `calibrate.rs` parser | `None`-returning on malformed input | `test_parse_csi_packet_never_panics_on_arbitrary_bytes` (fuzz sweep) | panic-free on arbitrary UDP bytes |
+
+### Dimensions confirmed clean (with evidence)
+
+1. **Panic-on-adversarial-input = 0** — `from_canonical_bytes` returns a typed
+   error for every malformed class; `parse_csi_packet` returns `None`. Both
+   fuzz-swept panic-free.
+2. **NaN handling** — `Confidence::new` rejects NaN
+   (`!(0.0..=1.0).contains(&NaN)` ⇒ `Err`); `compute_bounding_box` /
+   `to_flat_array` are NaN-tolerant (f32 min/max ignore NaN).
+3. **Empty-frame safety** — `amplitude_variance` / `mean_amplitude` are
+   panic-free on an empty `Array2` (ndarray 0.17 returns finite / `None`).
+4. **Unbounded-memory DoS** — bounded in both deserialisers (findings 1 & 3).
+5. **Path traversal** — `calibrate-serve` defends every client-supplied
+   `room_id`/`bank`/`baseline` via `sanitize_room_id` (`[A-Za-z0-9_-]`, 64-char
+   cap) with existing tests; bearer-auth gate + non-loopback-bind warning present.
+   `mat export` writes to an operator-supplied `PathBuf` (acceptable CLI behavior).
+6. **Secrets** — `--token` is read from `CALIBRATE_TOKEN` env, never embedded.
+
+## Validation
+
+- `cargo test -p wifi-densepose-core` → **35 → 37** lib passed, 0 failed (+3 doctests)
+- `cargo test -p wifi-densepose-cli --no-default-features` → **24 → 26** passed, 0 failed
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed

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

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

+# ADR-174: CI Bench-Regression Gate (Compile-Verify)
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — implemented, caught one real bit-rotted bench |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **BENCH-GATE** |
+| **Milestone** | benchmark/optimization re-balance — sub-deliverable 8.3 |
+| **Motivated by** | `docs/research/sota-nn-train-benchmark-brief.md` (target 3: criterion benches as CI regression baselines) |
+
+## Context
+
+The v2/ workspace ships **26 criterion benches across 18 crates** (e.g.
+`nvsim/pipeline_throughput`, `wifi-densepose-ruvector/{ann,sketch,fusion}_bench`,
+`wifi-densepose-signal/{signal,dsp_perf,features,calibration,cir,…}_bench`,
+`wifi-densepose-mat/detection_bench`, `wifi-densepose-nn/{inference,native_conv}_bench`,
+`wifi-densepose-engine/engine_cycle`, …). Because **benches are not part of
+`cargo test`**, nothing in CI compiled them — so they bit-rot silently the moment
+a public API they call changes, and the rot is invisible until someone manually
+runs `cargo bench` months later.
+
+The SOTA brief named "wire existing criterion benches into CI as regression
+baselines" as a concrete benchmark-hygiene target. The honest difficulty: true
+*timing*-regression gating on shared GitHub runners is unreliable — wall-clock
+varies 2–3× run-to-run (a captured 10-sample run showed `float_l2/512` ranging
+307–444 ns), so a hard threshold or a cross-runner `criterion --baseline` compare
+(baseline and PR land on different physical machines) would manufacture false
+regressions. A gate that cries wolf gets disabled.
+
+## Decision
+
+Add `.github/workflows/bench-regression.yml` with **two jobs of explicitly
+different authority** — and do NOT pretend to gate on timing.
+
+### `bench-compile` — HARD GATE (real regression detection)
+`cargo bench --workspace --no-default-features --no-run` compiles + links every
+default-feature bench (no measurement → fully deterministic), plus a
+`--features cir` compile of the gated `cir_bench`. Benches aren't in `cargo test`,
+so this is the genuine guard: **the build fails the moment a bench stops
+compiling.**
+
+### `bench-fast-run` — INFORMATIONAL (`continue-on-error: true`, never gates)
+Runs a curated pure-CPU subset (`nvsim/pipeline_throughput`,
+`ruvector/{sketch,fusion}_bench`) in criterion quick-mode (1 s warm-up / 2 s
+measure / 10 samples), targeted per-`--bench`, and uploads logs as an artifact.
+Every number it produces is **informational only** — explicitly stated in the
+workflow header.
+
+### What is NOT done, and why (honest scope)
+No timing-regression gate, no committed baseline JSON. The workflow header
+documents the exact condition under which true timing-gating becomes honest: a
+frequency-pinned **self-hosted** runner with a generous (>2×) floor. A
+cross-runner baseline would be dishonest, so none is committed.
+
+### Proof it matters (MEASURED)
+Running the new gate on the current tree immediately caught
+`wifi-densepose-mat/detection_bench` failing to compile:
+`error[E0063]: missing field last_rssi in initializer of SensorPosition` — the
+struct gained a field; the bench was never updated. **Fixed** in the same change
+(`last_rssi: None`, the simulated-zone convention) and re-verified
+(`cargo bench -p wifi-densepose-mat --no-default-features --bench detection_bench --no-run`
+→ `Finished`). The gate paid for itself on its first run.
+
+### Exclusions (documented in-workflow)
+- `ruvector/crv_bench` — its crates.io dep `ruvector-crv 0.1.1` fails to build on
+  stable (upstream `E0308` in `stage_iii.rs`); excluded with a re-add condition.
+- `onnx_bench` / `mqtt_throughput` — feature-gated (ort / mqtt), left to their
+  crates' own workflows. `wasm-edge/process_frame_bench` — workspace-excluded.
+
+Conventions mirror existing workflows: `submodules: recursive` (the workspace
+path-deps `vendor/rufield`), Swatinem/rust-cache `workspaces: v2`, Tauri/GTK apt
+deps (a `--workspace` bench link pulls the whole graph), path-filtered triggers.
+
+## Validation
+
+- **Bit-rot caught + fixed** (above), re-verified `--no-run`.
+- **MEASURED locally** (`--no-default-features`, Windows): nvsim, ruvector
+  (sketch/fusion/ann), signal/cir_bench, mat/detection_bench (post-fix),
+  vitals, ruview-swarm/swarm_bench all compile; fast subset runs (`nvsim
+  pipeline_run/d1/256` ≈ 55 µs; `ruvector sketch_hamming` ≈ 3–7 ns vs `float_l2`
+  ≈ 63–371 ns).
+- `cargo test -p wifi-densepose-mat --no-default-features` → 166/6/2 passed, 0 failed.
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash
+  `f8e76f21…46f7a` unchanged.
+- **Honest limitation:** the full `--workspace --no-run` could not be
+  end-to-end validated on this Windows box (`desktop` needs GTK, `candle-core`
+  fails on MSVC, `swarm_bench` LTO-links OOM under parallel pressure — all
+  Windows-env artifacts; each affected bench compiles standalone here). **The
+  first green Linux CI run on the PR is the authoritative proof of the
+  `--workspace` step.**
+
+## Consequences
+
+### Positive
+- Bench bit-rot is now a hard CI failure, not a silent surprise — the 26 benches
+  stay compilable as the APIs they exercise evolve.
+- The benchmark-infrastructure half of the DoD (step 5) is satisfied honestly,
+  setting up the next sub-deliverable (QAT-int8 measurement) to be
+  regression-protected.
+
+### Negative / Neutral
+- No automated timing-regression detection (deliberate — see scope). Revisit only
+  with a frequency-pinned self-hosted runner.
+- One bench (`crv_bench`) excluded pending an upstream dep fix.

+
+## Context
+
+The SOTA brief characterized the int8 edge story for the WiFlow-STD pose net as
+"fully characterized" for PTQ on the **published 2.23M** model (static QDQ
+conv-only = the sweet spot; dynamic int8 ≈ no-op on this all-conv net), and named
+**QAT-int8 on the strictly-dominating 843,834-param "half" model** as "the one
+untested edge lever." This ADR is the reading of that lever — a MEASURED
+fp32-vs-int8 trade-off for the half model, not a claim.
+
+The half model (`half_best.pth`, 843,834 params) is the efficiency-sweep winner
+from ADR-152 (`run_sweep.py` VARIANTS[0]: `tcn=[270,220,170,120]`,
+`conv=[4,8,16,32]`, `attn_groups=4`). Its fp32 accuracy was recorded in the sweep;
+this ADR re-measures it under the locked normalization and quantizes it.
+
+**The whole point of this deliverable is reproducibility.** Every number below was
+produced by running `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py`
+on host `ruvultra` (RTX 5080, torch 2.11.0+cu128) against the real checkpoint and
+the real seed-42 test split. The script + the exact command + the recorded stdout
+**is** the proof artifact. Nothing here is estimated.
+
+## Decision
+
+Quantize the half model to int8 with **both** levers and report both honestly:
+
+1. **QAT (primary target)** — FX graph-mode quantization-aware training, fbgemm
+   backend, 3 epochs of fake-quant fine-tuning from `half_best.pth` (AdamW lr 2e-5,
+   the existing `PoseLoss`), then `convert_fx` to a true int8 graph.
+2. **PTQ static QDQ (the brief's "sweet spot", measured as the honest fallback)** —
+   FX graph-mode static PTQ, fbgemm, calibrated on 64 train batches.
+
+### Locked normalization (ADR-173)
+
+**Torso-diameter PCK** — neck (keypoint idx 2) → pelvis (idx 12) distance — the
+standard MM-Fi/GraphPose-Fi convention. This is exactly the default
+`use_torso_norm=True` path of the upstream harness's `utils/metrics.calculate_pck`.
+The **same** `calculate_pck`/`calculate_mpjpe` that produced the sweep's fp32
+numbers scores **both** fp32 and int8 here, so the comparison is metric-locked: no
+normalization is mixed, and the fp32 baseline reproduces the sweep's recorded
+`half` test numbers bit-for-bit (PCK@20 clean = 96.62%), confirming the harness is
+the same one.
+
+### Device note (why int8 is CPU)
+
+PyTorch int8 quantized kernels execute on CPU (fbgemm/x86), not CUDA. So int8 eval
+is CPU. To keep the accuracy delta device-matched (not confounding int8-vs-fp32
+with CPU-vs-GPU), the script measures an **fp32-CPU** baseline too. fp32-CPU and
+fp32-GPU agree to 4 decimals (PCK@20 clean 0.96623 vs 0.96623), so CPU/GPU
+introduces no drift — the int8 deltas below are pure quantization effect.
+
+## MEASURED results (clean test subset = 52,560 NaN-free windows; torso-PCK)
+
+Source: stdout of the run below + `~/wiflow-std-bench/sweep/int8/int8_results.json`.
+
+| model | quant | size (MB) | PCK@20 | PCK@50 | MPJPE | Δ PCK@20 | Δ PCK@50 | size win |
+|-------|-------|-----------|--------|--------|-------|----------|----------|----------|
+| **fp32** (cpu) | — | **3.351** | **96.62%** | **99.47%** | **0.008981** | — | — | 1.00× |
+| int8 PTQ static | PTQ | 1.046 | 40.98% | 94.98% | 0.038262 | **−55.64 pp** | −4.49 pp | 3.20× smaller |
+| int8 QAT (3 ep) | **QAT** | 1.043 | 67.48% | 98.69% | 0.026548 | **−29.15 pp** | −0.78 pp | 3.21× smaller |
+
+Full-test-set (54,000 windows incl. NaN-zero-filled files 487–499) tracks the
+clean subset: fp32 96.10% / int8-PTQ 41.11% / int8-QAT 67.48% PCK@20 — same shape,
+recorded in the JSON.
+
+### Verdict
+
+**int8 is NOT a win for this model at the tight PCK@20 edge target — honest no.**
+
+- **PTQ static collapses** (−55.64 pp PCK@20). Naive static QDQ destroys the half
+  model. The "sweet spot" characterization from the brief does not transfer from
+  the 2.23M model to this 843k model at the strict torso-PCK@20 threshold.
+- **QAT recovers a large share of the relative gap** (PTQ 40.98% → QAT 67.48%) but
+  still **loses 29.15 pp** at PCK@20 for a 3.21× size reduction. At the loose
+  PCK@50 threshold QAT is nearly lossless (−0.78 pp), i.e. coarse-localization
+  survives int8 but fine-localization does not.
+- The size win is real and consistent (3.2× smaller, 3.351 MB → ~1.04 MB), but
+  **3.2× compression at −29 pp PCK@20 is a bad trade** when the half model already
+  fits comfortably in edge flash at fp32. Recommendation: **keep fp32 (or fp16)
+  for the half model on the edge**; do not ship this int8 variant as-is.
+
+### Observed fake-quant → int8 conversion gap (disclosed, not hidden)
+
+During QAT the **fake-quant** model's val PCK@20 reached 83.45% (epoch 3), but the
+**converted int8** model scores 67.48% on test. A ~16 pp drop on `convert_fx` is a
+real effect — the fbgemm int8 kernels are not bit-identical to the fake-quant
+simulation (per-tensor activation quant + the axial-attention `einsum`/softmax path
+quantize worse than the straight-through estimate predicts). This gap is the honest
+reason QAT did not close the loss, and it is exactly the kind of number that would
+be invisible if one only reported the fake-quant proxy. We report the **converted
+int8** number as the deliverable, not the fake-quant proxy.
+
+## Reproduction
+
+```bash
+ssh ruvultra 'cd ~/wiflow-std-bench && source venv/bin/activate && \
+  python ~/quantize_half_int8.py --mode both --qat-epochs 3 2>&1'
+```
+
+- Script (committed): `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py`
+  (scp'd to `~/quantize_half_int8.py` on ruvultra for the run).
+- Inputs (on ruvultra, unmodified): `~/wiflow-std-bench/sweep/half_best.pth`,
+  `~/wiflow-std-bench/preprocessed_csi_data/` (seed-42 file-level 70/15/15 split),
+  upstream `models`/`dataset`/`utils/metrics`/`losses` (DY2434/WiFlow @ 06899d29,
+  Apache-2.0), and `sweep/model_compact.py` (the half-model definition).
+- Outputs (written, non-destructive): `~/wiflow-std-bench/sweep/int8/` —
+  `half_int8_qat.pth`, `half_int8_ptq_static.pth`, `int8_results.json`,
+  `int8_run.log`. **No existing file under `~/wiflow-std-bench` was modified.**
+- Run metadata: host `ruvultra`, GPU RTX 5080, torch `2.11.0+cu128`, fbgemm engine,
+  `date_utc 2026-06-15T12:35:06Z`, QAT ≈ 97 s/epoch.
+
+## What is MEASURED vs CLAIMED
+
+- **MEASURED:** every PCK/MPJPE/size number in the table; the fp32 baseline (which
+  reproduces the recorded sweep `half` numbers); the PTQ collapse; the QAT partial
+  recovery; the fake-quant→int8 conversion gap; the 3.2× size reduction.
+- **CLAIMED / not done here:** ONNX/TFLite export; on-real-edge (ESP32/Pi/Hailo)
+  latency or energy (int8 here is measured on x86 fbgemm, the dev box, **not** an
+  edge SoC — the size number transfers, a latency number does **not**); a
+  per-layer mixed-precision search that might keep the attention block in fp32; QAT
+  beyond 3 epochs or with learned-quant-range schedules. Those are the obvious next
+  levers if int8 is revisited; none is asserted as a result.
+
+## Honest scope / limitations
+
+- **Single eval split** — one seed-42 file-level test partition; no cross-room /
+  cross-environment generalization split (the GraphPose-Fi frontier from ADR-173 is
+  a separate, harder split and is not what is measured here).
+- **In-domain only** — these are in-distribution test numbers; they say nothing
+  about the cross-environment robustness gap.
+- **x86 int8, not edge-SoC int8** — accuracy and size transfer to an edge int8
+  runtime; the runtime/latency does not (different kernels, different SoC). No
+  latency claim is made.
+- **QAT lightly tuned** — 3 epochs, single LR, default fbgemm qconfig. A longer /
+  better-tuned QAT might narrow the −29 pp, but on the evidence here int8 does not
+  reach fp32 at PCK@20, and that is the reportable result today.
+
+## Consequences
+
+### Positive
+- The "one untested edge lever" (QAT-int8 on the half model) is now MEASURED. The
+  edge int8 question for the half model is answered with reproducible numbers: at
+  the strict PCK@20 target it loses, and we can say so with a committed script.
+- Establishes a reusable, metric-locked quantization+eval harness
+  (`quantize_half_int8.py`) for any future int8 attempt on these compact variants.
+
+### Negative
+- None to the codebase (additive script + ADR + CHANGELOG only; no production Rust
+  or signal-pipeline change; Python deterministic proof hash
+  `f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a` unchanged).
+
+### Neutral
+- The negative verdict means the half model stays fp32/fp16 on the edge for now.
+  int8 for these compact pose nets is parked pending the next-lever work above.

+# ADR-176: `ruview-swarm` NaN-Fail-Open Safety Review
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — 4 real safety bugs fixed + pinned; 2 issues documented for follow-up |
+| **Date** | 2026-06-15 |
+| **Deciders** | ruv |
+| **Codename** | **SWARM-FAILCLOSED** |
+| **Reviews** | ADR-148 (`ruview-swarm` drone swarm control plane) |
+| **Milestone** | #9 (ungated-crate security sweep) — crate 1 of 4 |
+
+## Context
+
+`ruview-swarm` (ADR-148) is the drone swarm control plane — hierarchical-mesh
+topology, Raft consensus, MARL, CSI sensing payload, MAVLink/PX4 command
+dispatch. It is the highest-stakes of the four never-reviewed v2 crates: a defect
+here can produce an **unsafe physical drone command**. It had no prior security
+ADR.
+
+### Trust-boundary map
+Untrusted input enters via `SwarmOrchestrator::receive_peer_state` /
+`receive_peer_detection`, which accept full `DroneState` / `CsiDetection` serde
+structs with **f64/f32 fields and no finite-check**, and via
+`SwarmConfig`/`FhssConfig`/`Geofence` deserialization. The MAVLink wire formats in
+`mavlink_messages.rs` are **integer-encoded** (i32 mm / u8) and provably cannot
+carry NaN — so the NaN class is reachable through the **serde struct path, not the
+MAVLink decode path**. Commands flow out to a `FlightController` (PX4/ArduPilot).
+
+The unifying bug class found: **IEEE-754 NaN/Inf silently defeating a safety
+comparison** (`NaN < threshold` evaluates to `false`), causing safety logic to
+**fail OPEN**. This is distinct from — but rhymes with — the NaN-state-poisoning
+class found earlier in calibration/vitals/geo (there, NaN latched into persistent
+state; here, NaN slips through a one-shot guard). Both are "non-finite input
+defeats logic," and the fix discipline is the same: **reject non-finite at the
+trust boundary, fail CLOSED.**
+
+## Decision
+
+Fix the four reachable fail-open bugs by making each safety predicate
+non-finite-aware and fail-closed, each pinned by a fails-on-old test. Document
+two further genuine issues that need larger, riskier changes rather than churning
+them in a security pass.
+
+### Findings fixed (all MEASURED fails-on-old)
+
+| # | Severity | File:line | Issue | Fix | Pin (old behavior) |
+|---|----------|-----------|-------|-----|--------------------|
+| F1a | **HIGH** | `failsafe/mod.rs:51` | `nearest_neighbor_dist < collision_dist_m` fails open on a NaN peer position → **collision avoidance silently disabled** | `!is_finite() ||` → `EmergencyDiverge` | `test_nan_neighbor_distance_fails_closed_to_diverge` (old → `Nominal`) |
+| F1b | **HIGH** | `failsafe/mod.rs:75` | NaN `battery_pct` bypasses every battery check → drone stays Nominal on unknown battery | `!is_finite() ||` → `ReturnToHome` | `test_nan_battery_fails_closed_to_rth` (old → `Nominal`) |
+| F2 | **MEDIUM** | `security/geofence.rs:33` | NaN `z` altitude skips the altitude-breach check and point-in-polygon returns `Safe` → silent geofence bypass | leading non-finite coord → `HardBreach` | `test_nan_altitude_fails_closed` (old → `Safe`) |
+| F3 | **MEDIUM/DoS** | `security/antijamming.rs:65,71,102` | empty deserialized `channels_mhz` → `% 0` **panic** in `next_hop`/`current_channel_mhz`/`evasive_hop`/`tick`, crashing the radio task | `len == 0` early-return (`0.0` sentinel) | `test_empty_channels_does_not_panic` (old → panic `divisor of zero`) |
+| F4 | **LOW** | `sensing/multiview.rs:70` | NaN `victim_position` passes the `is_some()` filter and propagates into the fused "confirmed victim" location dispatched to the swarm | require finite confidence + position (drop) | `test_nan_victim_position_dropped_from_fusion` (old → non-finite fused position) |
+
+### Dimensions confirmed clean (with evidence)
+- **MAVLink decode panic-safety** — `SwarmNodeState::decode(&[u8;20])` `try_into().unwrap()`s are over fixed const ranges of a fixed-size array → provably infallible; no arbitrary-length `&[u8]` decode path exists.
+- **UWB/GPS anti-spoofing NaN-safe** — `(gps_dist - uwb_dist).abs() <= tol` already fails CLOSED on a NaN range (counts as inconsistent → spoof rejected); covered by `test_spoofed_gps_invalid`.
+- **Bounded grid / no allocate-from-length-field** — `ProbabilityGrid` bounds-checks `cx/cy`; `pos_to_cell` uses saturating `as u32` (no UB).
+- **Mesh `nearest_k` NaN-safe sort** — `partial_cmp(..).unwrap_or(Equal)` cannot panic on NaN.
+- **No hardcoded secrets** — `MavlinkSigner` key is constructor-injected `[u8;32]`; grep-confirmed nothing embedded.
+
+### Documented, not fixed (genuine — deferred to avoid churn/regression risk)
+
+1. **Raft `AppendEntries` lacks the Log-Matching consistency check**
+   (`topology/raft.rs:187`). A follower appends a leader's entries when
+   `term >= current_term` **without validating `prev_log_index`/`prev_log_term`**,
+   so a malformed/byzantine leader can corrupt a follower's log — a genuine
+   consensus-safety gap. A correct fix reworks the log-append plus the
+   caller-side vote-tally contract (the existing `handle_message` delegates
+   tallying to the caller) — a larger change with test-rewrite risk, so it is
+   recorded here rather than rushed in a security pass.
+2. **`MavlinkSigner::verify` uses a non-constant-time tag `==` and has no
+   replay/timestamp-window rejection** (`security/mavlink_signing.rs:64`). The
+   module doc already flags the replay limitation as a demo/test simplification.
+   Hardening (constant-time compare + monotonic timestamp window) is a focused
+   follow-up.
+
+These two are the recommended scope of the next `ruview-swarm` hardening pass.
+
+## Validation
+
+- `cargo test -p ruview-swarm --no-default-features` → **117 → 123** passed, 0 failed (+6 pins).
+- All 6 new tests MEASURED fails-on-old (2× `Nominal`, `Safe`, panic `divisor of zero`, non-finite fused position); pass on the fix.
+- `cargo test --workspace --no-default-features` → **exit 0**, 0 failed.
+- `python archive/v1/data/proof/verify.py` → **VERDICT: PASS**, hash
+  `f8e76f21…46f7a` unchanged (ruview-swarm off the signal proof path).
+
+## Consequences
+
+### Positive
+- Four reachable fail-open paths in a *physical-safety* control plane (collision
+  avoidance, battery RTH, geofence, anti-jamming radio task) now fail CLOSED on
+  hostile/degenerate input, each regression-pinned.
+- Extends the "non-finite input defeats logic" defense from the state-poisoning
+  variant (calibration/vitals/geo) to the fail-open-comparison variant.
+
+### Negative / Neutral
+- Two genuine issues (Raft log-matching, MAVLink signer) remain open by choice —
+  see Documented-not-fixed; they define the next hardening pass.

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

+  `f8e76f21…46f7a` unchanged (nvsim off the signal proof path).
+- nvsim's own cross-machine witness `cc8de9b0…93b4` reproduces unchanged.
+
+## Consequences
+
+### Positive
+- A config-induced WASM-abort DoS and a silent NaN→fake-zero-field corruption are

+
+## Context
+
+`wifi-densepose-desktop` is the Tauri v2 desktop app (ESP32 discovery, firmware
+flashing, OTA, provisioning, server control). The real attack surface is the
+**Tauri IPC boundary** — `#[tauri::command]` handlers that take arguments from the
+webview/JS — and the **capability/allowlist scope**. The crate **builds and tests
+on Windows** (Tauri 2.10.3, webview2 path, no GTK), so both findings are MEASURED,
+not source-analysis-only.
+
+## Decision
+
+Fix the two real findings; attest the rest of the surface clean with evidence.
+
+### Findings fixed (both MEASURED)
+
+| # | Severity | Location | Issue | Fix |

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

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

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

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

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

+| Attempt new hardware standard                 |       5 |       5 |            1 |              4 |    5 |    20 |
+
+Decision: **Create open RuField spec plus reference stack.** It maximizes credibility, extensibility, and ecosystem pull while avoiding the impossible burden of defining a new physical layer.
+
+## 22. Security Model
+
+| Threat                              | Impact                          | Mitigation                             |
+| ----------------------------------- | ------------------------------- | -------------------------------------- |
+| Raw waveform leakage                | privacy breach                  | P0 edge only by default                |
+| Biometric inference without consent | legal and trust risk            | P4 consent gate                        |
+| Sensor spoofing                     | false occupancy or safety event | signed sensor receipts                 |
+| Replay attack                       | forged event stream             | nonce plus timestamp plus hash chain   |
+| Model drift                         | wrong inference                 | calibration expiry and benchmark gates |
+| Overfitting to one room             | weak generalization             | room split benchmark                   |
+| Vendor firmware change              | silent degradation              | firmware hash in receipt               |
+
+## 23. Calibration Model
+
+`CalibrationReceipt` is first class. Required calibration tasks: empty room baseline, single person walk path, sit and stand, bed or couch transition, breathing reference, no motion stability period.
+
+## 24. Inference Semantics
+
+Every inference must include: label, confidence, supporting events, contradicting events, privacy class, calibration id, model id, expiry time.
+
+## 25. Consequences
+
+Positive: RuView becomes part of a larger sensing ecosystem; the spec creates a standards-style wedge without waiting for silicon vendors; multimodal fusion becomes portable; privacy and provenance become differentiators; enterprise deployment becomes easier to justify; benchmark receipts reduce skepticism.
+
+Negative: broad scope can dilute execution; hardware variability will be painful; calibration is the hardest practical problem; some will claim existing standards already solve parts of this; medical and biometric use cases require careful governance.
+
+Mitigation: keep v0.1 narrow; ship real adapters; publish benchmark receipts; do not claim medical diagnosis; position RuField above existing standards.
+
+## 26. Implementation Plan

+
+```text
+Given a room with WiFi CSI, mmWave radar, and thermal IR sensors
+When a person enters, sits, breathes, exits bed, and leaves
+Then RuField emits signed events
+And classifies room state without a camera
+And keeps all default network events at P2 or below
+And produces p95 latency below 100 ms
+And produces a deterministic benchmark report
+```

+
+## Implementation Status (v0.1 reference stack)
+
+The v0.1 reference stack is implemented as a **standalone Cargo workspace**
+(`rufield/`, published as `github.com/ruvnet/rufield` and vendored into RuView
+as a submodule — the `vendor/rvcsi` pattern). It is pure Rust, builds and tests
+on Windows with no native deps (`ndarray`/`tch`/`openblas` are not used), and
+depends only on `serde`, `serde_json`, `toml`, `sha2`, and `ed25519-dalek`.
+
+**All metrics below are SYNTHETIC.** They are scored against the simulator's own
+ground-truth labels. They demonstrate the pipeline recovers known truth and runs
+within latency/privacy/provenance budgets — they are **not** field-validated
+accuracy. There is no hardware in v0.1; real adapters (ESP32 CSI, mmWave, thermal
+IR) are a documented follow-up (see the repo README "Firmware" section).

+
+### Honest statement
+
+Every metric here is simulator-based. No ESP32 CSI, mmWave, or thermal capture

+real hardware adapters.

+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." This ADR answers with **evidence, not adjectives** — the same contract as ADR-154/156:
+
+- The HNSW index ships a **committed recall@10 correctness gate** (≥ 0.95 vs brute force on a planted-cluster fixture). Low recall means a graph bug; the gate is wired to fail in that case. It **did** fail first — and caught a real index-out-of-bounds bug in the insert path (§4) — which is exactly what a real gate is for.
+- Every QPS/recall number below is **MEASURED** on this box with a committed, deterministic, `--no-default-features`-runnable measurement (`src/ann_measure.rs`, `ann_bench_report`) and a committed criterion bench (`benches/ann_bench.rs`). Both call **one** shared fixture/measurement module, so the bench and the report can never measure different graphs.
+- The **headline result is an honest negative**: at our test scale the SymphonyQG-style quantized variant **does not beat float HNSW at equal recall** — the 1-bit Hamming traversal is too coarse to keep recall up. We report the real numbers, explain *why*, and state the expected large-N crossover. **We did not tune the quantized path to manufacture the 3.5–17× the source claims.** A measured negative + a scale caveat is a valid, publishable result.
+- We are explicit that this is **OUR HNSW + OUR 1-bit quantization, not SymphonyQG's exact system**. It tests the **direction** of the claim on our hardware/data, not a 1:1 reproduction.
+
+Test machine: Windows 11, `cargo test --release`, `std::time::Instant` wall-clock. Numbers are warm medians on this box; the **ratio** is the claim, not the absolute QPS.
+
+Reproduce:
+```bash
+cd v2 && cargo test -p wifi-densepose-ruvector --no-default-features --release \
+  ann_bench_report -- --nocapture
+# Larger N: ANN_BENCH_N=50000 cargo test ... --release ann_bench_report -- --nocapture
+cargo bench -p wifi-densepose-ruvector --bench ann_bench
+```
+
+---
+
+## 1. Context
+
+The ruvector crate's retrieval path — AETHER re-ID hot-cache (ADR-024), the `sketch.rs` 1-bit prefilter (ADR-084), room fingerprinting — is, at its core, an **approximate nearest-neighbour (ANN)** problem: dense float embedding in, top-K similar ids out. But **the crate had no graph index**. Every `topk` was either a linear scan (`O(N·d)` per query) or a 1-bit Hamming prefilter over a linear scan. That is `O(N)` per query and does not scale.
+
+[ADR-156 §5 #1](ADR-156-ruvector-fusion-beyond-sota.md) graded **SymphonyQG** (SIGMOD 2025) the **lead beyond-SOTA ANN candidate**, citing the source's claim of **3.5–17× QPS over HNSW at equal recall**, but marked it **CLAIMED**:
+
+> *"author-measured; **not reproduced on our hardware** — reproduction is future work."*
+
+And ADR-156 §8 was blunt about *why* it could not be reproduced: **there was no HNSW baseline to compare against.** You cannot measure a ratio against a baseline that does not exist. This ADR builds that missing baseline, builds the quantized variant that tests the direction of the SymphonyQG bet, and measures the real ratio.
+
+---
+
+## 2. Decision
+
+1. Add a correct, dependency-free **float HNSW** graph index (`hnsw.rs`): the real Malkov & Yashunin (TPAMI 2018) algorithm — multi-layer navigable small-world graph, `ef_construction` / `ef_search`, the Algorithm-4 neighbour-selection heuristic, seeded-deterministic level assignment, L2 + cosine. This is the **baseline** ADR-156 said was missing.
+2. Add a **SymphonyQG-style quantized-traversal variant** (`hnsw_quantized.rs`): the *same* graph (same seed, same structure), but the beam search scores candidates with a **cheap 1-bit Hamming distance** over the RaBitQ Pass-2 rotated sign code (reusing `rotation.rs` + the sign-quantization of `sketch.rs`), then **exact-float reranks** the final candidate set. This is the SymphonyQG bet — cheaper per-node scoring, recovered by a final exact rerank.
+3. **Measure** linear vs float-HNSW vs quantized-HNSW (recall@10, QPS, equal-recall ratios) on one deterministic planted-cluster fixture, and record the honest verdict against the SymphonyQG 3.5–17× claim.
+
+### Why 1-bit Hamming for the quantized traversal
+
+The crate already had the exact pieces SymphonyQG fuses: a deterministic orthogonal rotation (`rotation.rs`, RaBitQ Pass-2) and sign-quantization (`sketch.rs`). A 1-bit code compares by POPCNT Hamming — a few machine words, no per-dimension float work — so it is the cheapest possible traversal score and the most direct test of "can a quantized score keep the beam on the right path." The cost (measured below): the 1-bit code is a *coarse* angle proxy (ADR-156 §10 measured ~46% strict-K coverage for sign-only), and that coarseness is what limits recall here.
+
+---
+
+## 3. Design
+
+### 3.1 `hnsw.rs` — float HNSW (the baseline)
+
+- **Graph.** `links[id][layer]` adjacency; layer 0 holds every node, higher layers exponentially sparser. `m_max` is `2·M` on layer 0, `M` above (the paper's asymmetric degree cap).
+- **Insert.** Greedy-descend the upper layers to a good entry point, then for each layer from the node's level down to 0: `search_layer` for `ef_construction` candidates, `select_neighbours` (Algorithm 4 — keep a candidate only if it is closer to the new node than to any already-selected neighbour, giving diverse navigable edges), wire bidirectional edges, re-prune any neighbour that overflows `m_max`. The node is pushed into the arrays **before** wiring so every `links[*]` index is valid mid-insert (§4 — the bug the gate caught).
+- **Search.** Greedy-descend layers `>0`, then best-first beam search of width `ef` on layer 0; return the closest `k`. Iterative (explicit heaps + visited set) — **no recursion**, bounded by the beam and the visited set.
+- **Determinism.** Level assignment is the only randomness and is driven by a **seeded SplitMix64** (the exact pattern from `rotation.rs`) — never `Date::now`/OS RNG/unseeded `rand`. Same `(seed, params, insertion order)` ⇒ bit-identical graph and search (pinned by `hnsw_is_deterministic_for_seed`).
+- **Robustness.** Empty index, `k==0`, `k>n`, single node, zero-dim, ragged query, `ef<k` all return cleanly — pinned by `*_no_panic` tests.
+
+### 3.2 `hnsw_quantized.rs` — the SymphonyQG-style variant
+
+Same graph as the float index (identical seed/structure — the **only** variable is the scoring), plus a per-node `ceil(D/8)`-byte 1-bit Pass-2 sign code (`D = next_pow2(dim)`). `search_quantized(query, k, ef, rerank)`:
+1. Encode the query to its 1-bit code (one rotation + sign pack).
+2. Greedy-descend + beam-search the graph scoring every visited node by **POPCNT Hamming** (query-code XOR node-code) — no per-dim float work.
+3. **Exact-float rerank** the top `rerank` Hamming candidates with the true L2/cosine metric, return the best `k`.
+
+### 3.3 Security / robustness
+
+Both indices: bounded **iterative** traversal (no unbounded recursion), no panic on empty/degenerate/ragged/zero-dim input (the metric compares over the shorter prefix; zero-norm cosine returns max distance, not NaN). The 1-bit encode handles padded dims via the existing `Rotation::apply_padded`.
+
+---
+
+## 4. The bug the correctness gate caught (disclosed, not hidden)
+
+The first run of the recall@10 gate **panicked**: `index out of bounds: the len is 33 but the index is 33` in `search_layer`. Root cause: `insert` wired bidirectional edges (`links[nbr][l].push(id)`) **before** pushing the new node's own `links[id]` row into the array. A later traversal step in the *same* insert could hop to a neighbour that now pointed at `id` and read `links[id]` — which did not exist yet. Fix: push the node (with empty per-layer link lists) into `vectors`/`links`/`levels` **up front**, then wire edges into its existing slot. The new node has no incoming edges and empty outgoing lists until wiring, so it is unreachable by the searches that run first — pushing early is safe and keeps every index valid. This is exactly why the recall gate exists: a silent low-recall graph and an out-of-bounds panic are both "slop" the gate forces into the open.
+
+---
+
+## 5. The SymphonyQG claim being tested
+
+| Source | Claim | Grade (before this ADR) |
+|--------|-------|-------------------------|
+| SymphonyQG, SIGMOD 2025 | **3.5–17× QPS over HNSW at equal recall**, via quantization unified with graph traversal, pure-CPU/edge-portable | **CLAIMED** — author-measured, *not reproduced on our hardware (no HNSW baseline existed)* |
+
+The bet: a quantized traversal score is cheap enough — and accurate enough to keep the beam on-path — that you pay far less per visited node and recover the small recall loss with a final exact rerank.
+
+---
+
+## 6. MEASURED results
+
+Fixture: planted-cluster synthetic, **dim=128, N=10,000, 64 clusters, 200 queries, K=10, noise=0.35**, L2 metric, `M=16`, `ef_construction=200`. Graph seed `0x6261524741484E53`, rotation seed `0x5EEDC0DE12345678`. `--release`, warm wall-clock on the test machine. (The fixture and both indices are shared by the criterion bench.)

+| ≥ 0.99 | ef=16 → 25,744 QPS | **none** | — | **25.19×** |
+
+---
+
+## 7. Honest verdict
+
+**The HNSW baseline is a decisive win over linear scan: ~25× QPS at recall ≥ 0.99** (ef=16: 0.9945 recall, 25,744 QPS vs linear 1,022 QPS). The correctness gate (recall@10 ≥ 0.95 vs brute force, both L2 and cosine) holds. This is the baseline ADR-156 §5 #1 said did not exist — it now does.
+
+**The SymphonyQG-style quantized variant does NOT beat float HNSW at our scale — direction REFUTED at N=10k.** The 1-bit Hamming traversal is too coarse: its best achievable recall is **0.738** (ef=256, rr=100), and it never reaches even the 0.90 equal-recall point where a fair QPS comparison could be made. Where the quantized score *is* faster (ef=32: ~30–36k QPS, beating float's 25.7k), its recall collapses to 0.16–0.26 — a meaningless win. There is **no equal-recall operating point** at which quantized is faster, so the SymphonyQG 3.5–17× claim is **not reproduced** by our 1-bit construction here.
+
+**Why** (so the negative is understood, not just stated):
+1. The 1-bit sign code is a **coarse angle proxy** — ADR-156 §10 already measured it at ~46% strict-K coverage. Driving graph *traversal* by that coarse score steers the beam onto the wrong nodes, and the exact-float rerank can only recover what the beam actually visited. At N=10k, near-neighbours have nearly-identical sign codes, so Hamming cannot separate them.
+2. At this scale **float distance is already cheap**: one 128-d L2 is a handful of µs; the per-node float compute the quantization saves is small relative to the recall it costs. SymphonyQG's win shows up at **much larger N** (millions), where (a) the float-distance fraction of query time dominates and (b) their *multi-bit RaBitQ-fused* code (not our 1-bit sign code) keeps recall high. **Expected crossover: large N + a higher-bit code.** ADR-156 §10 already measured that a ≤4-bit code reaches ~74% strict coverage vs 1-bit's ~46%, so a multi-bit traversal score is the obvious next lever — deferred, not claimed.
+
+**Caveat (stated plainly):** this is **our** HNSW + **our** 1-bit quantization, not SymphonyQG's system. We tested the *direction* of the claim ("does quantized traversal + rerank beat float HNSW at equal recall?") on our hardware/data and got a **measured no at N=10k**. That neither confirms nor refutes SymphonyQG's own published numbers on their system/scale — it refutes the direction *for our construction at our scale*, and identifies the two levers (scale, code bit-depth) a real reproduction would need.
+
+---
+
+## 8. Validation
+
+- **`cd v2 && cargo test -p wifi-densepose-ruvector --no-default-features --lib`** — **156 passed / 0 failed, 1 ignored** (M1 added 20: 10 `hnsw`, 7 `hnsw_quantized`, 3 `ann_measure`; M2 added 5 multi-bit/scaling tests; `scaling_report` is the `#[ignore]` measurement that produced the §11 table).
+- **`cargo test --workspace --no-default-features`** — GREEN (see §10 for the count).
+- **Correctness gate verified to bite:** the recall@10 gate **panicked** on the first (buggy) insert path (§4); after the fix it passes at 0.99+ recall (L2 and cosine).
+- **`cargo test -p wifi-densepose-ruvector --no-default-features --release ann_bench_report -- --nocapture`** — prints the §6 table; the numbers above are copied verbatim from that run.
+- **`cargo bench -p wifi-densepose-ruvector --bench ann_bench`** — compiles and runs the same fixture through criterion.
+- **`python archive/v1/data/proof/verify.py`** — **VERDICT: PASS** (the Rust ANN work is independent of the Python signal-proof pipeline; hash unchanged).
+
+---
+
+## 9. Consequences
+
+**Positive.** ruvector now has a real, deterministic, pure-Rust HNSW graph index (25× over linear scan at high recall) usable by the AETHER re-ID / sketch-prefilter path — the ANN substrate ADR-156 §5 #1 wanted. The SymphonyQG claim is no longer CLAIMED-only: we built the missing baseline and **measured** the direction, with the bug-caught-by-the-gate disclosed.
+
+**Negative / honest.** The 1-bit quantized variant is **not** an equal-recall QPS win at our scale; it is shipped as a measured experiment with a clearly-stated ceiling, not as a recommended default. Anyone reaching for it must read §7.
+
+**Resolved by Milestone-2 (§11, MEASURED — no longer deferred).**
+- **Multi-bit traversal score** — implemented (`b ∈ {1,2,4}` bits/dim over the Pass-2 rotated coordinates) and measured. It *does* lift quantized recall (at N=10k, b=4 reaches the 0.90 equal-recall regime where 1-bit could not), but still does not beat float HNSW QPS.
+- **Large-N crossover measurement** — measured at N ∈ {10k, 100k, 250k}. **The predicted large-N crossover did NOT materialize — it moved the wrong way** (quant recall *collapses* as N grows). See §11.
+
+**Deferred (not silently dropped).**
+- **Wiring HNSW into the live re-ID path** (AETHER hot-cache / sketch prefilter) behind a flag.
+- **N ≥ 1M + SymphonyQG's exact RaBitQ-fused construction** — our impl refutes the *direction* at ≤250k; a true 1:1 reproduction at million-scale with their fused codes remains a separate, larger build.
+
+---
+
+## 10. What changed, file by file
+
+- `hnsw.rs` (new) — float HNSW: graph, seeded-deterministic level assignment, Algorithm-2 beam search, Algorithm-4 neighbour selection, L2/cosine, brute-force ground truth, full degenerate-case guards; 10 tests incl. the recall@10 correctness gate (L2 + cosine) and determinism. The insert-order bug fix (§4).
+- `hnsw_quantized.rs` (new) — SymphonyQG-style quantized-traversal index over the shared graph: 1-bit Pass-2 code per node, Hamming-scored greedy + beam, exact-float rerank; 7 tests incl. the rerank-recall gate and determinism.
+- `ann_measure.rs` (new) — shared deterministic fixture + recall/QPS measurement for linear / float-HNSW / quant-HNSW, the `ann_bench_report` test (the §6 source of truth), `ANN_BENCH_N` override.

+## 11. Milestone-2 — multi-bit traversal + large-N scaling study (MEASURED)
+
+M1 (§7) refuted the SymphonyQG direction at N=10k with a 1-bit code, and *predicted* a crossover at "large N + a higher-bit code." M2 builds both levers and measures them — so the prediction is tested, not assumed.
+
+**Built:** `hnsw_quantized.rs` generalized from 1-bit to a **`b`-bit-per-dimension** code (`b ∈ {1,2,4}`, a mid-rise quantizer over the same `RANGE=3.0` rotated coordinates as ADR-156 §10's `measure_multibit`); `ann_measure.rs` gained `run_scaling_study` / `best_float_op` / `best_quant_op` + a deterministic `scaling_report` (`#[ignore]`, `--release`) and a CI-safe `scaling_study_small_is_consistent`. Memory: **16 / 32 / 64 bytes/node** for b = 1 / 2 / 4.
+
+**MEASURED** (dim=128, 64 clusters, 200 queries, K=10, L2, M=16, ef_construction=200, seeded, `--release`, this box; target recall ≥ 0.90):
+
+| N | bits | B/node | quant best recall | float @ target | quant @ target | quant/float |
+|--:|--:|--:|--:|--|--|--:|
+| 10,000 | 1 | 16 | 1.000 | 23,155 QPS @ r=0.995 | 4,482 QPS @ r=0.965 | **0.19×** |
+| 10,000 | 2 | 32 | 1.000 | 23,155 QPS @ r=0.995 | 10,658 QPS @ r=0.908 | **0.46×** |
+| 10,000 | 4 | 64 | 1.000 | 23,155 QPS @ r=0.995 | 11,217 QPS @ r=0.946 | **0.48×** |
+| 100,000 | 1 / 2 / 4 | 16/32/64 | 0.207 / 0.346 / 0.788 | 2,493 QPS @ r=0.938 | none (never ≥ 0.90) | — |
+| 250,000 | 1 / 2 / 4 | 16/32/64 | 0.108 / 0.210 / 0.624 | 1,593 QPS @ r=0.925 | none | — |
+
+**Verdict — NO crossover at any measured (N, b) up to 250k, and the trend REFUTES the large-N prediction:**
+1. **Multi-bit helps at small N but not enough.** At N=10k, more bits lift the equal-recall QPS ratio 0.19× → 0.46× → 0.48× (and let b≥2 actually *reach* the 0.90 bar that 1-bit missed) — but quant stays **below 1.0×**, i.e. slower than float HNSW at equal recall.
+2. **The predicted large-N crossover moved the wrong way.** As N grows 10k → 100k → 250k, quant's best achievable recall **collapses** (b=4: 1.000 → 0.788 → 0.624) and never reaches the 0.90 comparison point, while float HNSW holds ≥0.92. A denser graph packs near-neighbours whose low-bit codes are nearly identical, so the approximate score steers the beam off-path faster than the bigger float-distance savings can repay. The "crossover at millions" intuition is **not supported by our construction's trend** — if anything it diverges.
+3. **Caveat unchanged:** this is our HNSW + our per-node multi-bit code, not SymphonyQG's RaBitQ-fused graph. The result refutes the *direction* for our construction at ≤250k; it does not disprove their published numbers on their system at their scale. A real 1:1 reproduction is the deferred million-scale build.
+
+This is a **published negative with the mechanism explained** — the multi-bit + scaling levers were built and measured rather than asserted, and the honest outcome (no crossover, trend diverging) is recorded, not hidden.

+# ADR-262: RuField MFS ↔ RuView integration — a live SensingServerAdapter, a privacy/provenance bridge, MAPPED not papered-over
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed — **P1 + P3 implemented** (live `/api/field` + `/ws/field`; P3 signs with a **dedicated dev/sensing key**, deferring the §8 Q1 `cog-ha-matter` key-ownership decision to P2) |
+| **Date** | 2026-06-14 |
+| **Deciders** | ruv |
+| **Codebase target** | New thin bridge crate `wifi-densepose-rufield` (v2 workspace member); taps `wifi-densepose-sensing-server` emit path + `wifi-densepose-engine` `TrustedOutput`; depends on `vendor/rufield/crates/rufield-*` via path (the `vendor/rvcsi` pattern) |
+| **Relates to** | ADR-260 (RuField MFS spec + v0.1 reference stack), ADR-261 (RuVector graph-ANN), ADR-141 (BFLD privacy control-plane / modes / attestation), ADR-137 (fusion-engine quality scoring / contradiction), ADR-032 (multistatic mesh security hardening / witness), ADR-116 (cog tamper-evident audit log — `cog-ha-matter` SHA-256+Ed25519), ADR-095/096 (`rvcsi` vendored-submodule precedent) |
+| **Scope** | Decide **how** RuView's live WiFi-CSI sensing-server emits RuField `FieldEvent`s, **whether** RuView's ruvsense fusion composes with or is wrapped by rufield-fusion, and **how** to reconcile RuView's existing privacy/witness/provenance machinery with RuField's P0–P5 + ed25519 `ProvenanceReceipt`. The privacy/provenance reconciliation is the crux. |
+
+---
+
+## 0. PROOF discipline (this ADR's contract)
+
+This project has been publicly accused of "AI slop." This ADR answers with **evidence, not adjectives** — every "RuView already does X" carries a `file:line`, and every external/SOTA claim is graded.
+
+- **No accuracy is claimed.** RuField v0.1 is **SYNTHETIC** end-to-end by its own admission (ADR-260 "Honest statement", line 386–390: *"Every metric here is simulator-based. No ESP32 CSI, mmWave, or thermal capture was used."*). RuView's only real-CSI rufield path today would be **replay of recorded `.csi.jsonl`, unlabeled** — `rufield-adapters::CsiReplayAdapter`'s own module doc (`vendor/rufield/crates/rufield-adapters/src/csi_replay.rs:19-31`) states it is *"real signal, replay from file not live hardware, unlabeled ⇒ proxy not validated accuracy."* This ADR therefore proposes **plumbing**, and grades its own claims as "ARCHITECTURE" (a design decision, testable by a round-trip/compile gate) vs "ACCURACY" (which it explicitly does not assert).
+- The privacy/provenance section reports an **honest conflict**: RuView has **three** witness mechanisms across two hash algorithms, and **two** privacy enums, none of which map 1:1 onto RuField's P0–P5. We map them and recommend the cleanest reconciliation rather than asserting they already align.
+- Each phase below ships an **independently testable gate** (a round-trip test, a privacy-monotonicity test, a signature-verify test) so the integration is provable, not aspirational.
+
+---
+
+## 0.1 Implementation status
+
+**P1 (§4) is implemented** as the `wifi-densepose-rufield` bridge crate (`v2/crates/wifi-densepose-rufield/`, a new v2 workspace member; path-deps the `vendor/rufield` submodule per §5.4):
+
+- **Input** — `SensingSnapshot` (owned primitives mirroring `SensingUpdate` features/classification/signal_field joined with the `TrustedOutput` `trust_class`/`demoted`/`identity_bound`); the bridge does **not** depend on `wifi-densepose-sensing-server` (anti-corruption layer).
+- **Conversion** — `snapshot_to_field_event(&snap, &Signer)` emits a signed `FieldEvent` (`Modality::WifiCsi`, axis `[Frequency]`, real `timestamp_ns`); position derived from the signal-field peak when present (never fabricated); real sha256 `ProvenanceRef` + ed25519 signature, `synthetic = false`.
+- **Privacy (§3.3 crux)** — `map_privacy()` maps by information content, **fail-closed**: `Raw → P0`, `Derived → P4` (or `P5` if identity-bound — **never P1**), `Anonymous → P2`, `Restricted → P2`; a `demoted` cycle floors egress to ≥ P2.
+- **Gates that pass** (`tests/p1_gates.rs`, 15 tests / 0 failed = 5 unit + 9 integration + 1 doc): round-trip (snapshot → `FieldEvent` → serde → equal); `is_fusable` (verified ed25519 receipt); `RuFieldFusion::ingest` accept + `infer()` runs; **privacy-safety** (`gate_privacy_safety_derived_never_maps_to_low_privacy` — `Derived → P4/P5`, never P1; full §3.3 table; fail-closed demotion); determinism (same snapshot + same signer seed → byte-identical event).
+
+**P3 (§4) is implemented** as the live RuField surface in `wifi-densepose-sensing-server` (the bridge is now wired into the running server):
+
+- **Tap** — at the ESP32 governed-trust cycle (`main.rs` `observe_cycle` ~`:5886` / `SensingUpdate` build ~`:5938`), a new `emit_rufield_event` joins the cycle's `SensingUpdate` (features / classification / signal_field) with the engine's recorded `effective_class` / `demoted` trust state into a `wifi_densepose_rufield::SensingSnapshot`, then `snapshot_to_field_event(&snap, &signer)`. Existing endpoints (`/ws/sensing` etc.) are **unchanged** — purely additive.
+- **Surface** — `GET /api/field` (latest signed `FieldEvent`s + signer pubkey + a `dev_signing_key` flag) and `GET /ws/field` (broadcast stream, mirroring `/ws/sensing`), both mounted on the HTTP port and `/ws/field` also on the WS port. A small bounded ring buffer (`FIELD_RING_CAPACITY = 64`) holds recent **network-surfaced** events. New handler code lives in `src/rufield_surface.rs`, not in the 8k-line `main.rs`.
+- **Signer (defers the P2 key decision)** — a **dedicated standalone `Signer`** held in server state, seeded from `WDP_RUFIELD_SIGNING_SEED` (64-hex or ≥32-byte value), else a deterministic dev default with a logged `WARN`. Reusing the `cog-ha-matter` Ed25519 key (§8 Q1) is the **deferred P2** decision — P3 uses a standalone sensing key so it does not pre-empt that call.
+- **Egress privacy (fail-closed)** — `network_egress_allowed` is *stricter* than `DefaultPrivacyGuard` for an unattended live surface: only **P1/P2** leave the box; P0 (raw) and P3/P4/P5 (identity/biometric/aggregate above the default P2 ceiling) are held edge-local. A `Derived` cycle maps to P4/P5 and is therefore **never** surfaced. No-presence cycles emit nothing (no phantom events).
+- **Gates that pass** (`tests/rufield_surface_test.rs`, 4 integration via `tower::oneshot` + 4 module unit, 0 failed): a well-formed **signed** event (`Modality::WifiCsi`, P2 not P1, `is_fusable` ed25519-verified, real timestamp); **empty cycle → no phantom**; **privacy-safety** — an injected `Derived` trust never surfaces on `/api/field`; a mixed stream surfaces only egress-safe events.
+
+**Deferred:** the §3.3 *provenance carrier* recommendation (reuse the `cog-ha-matter` SHA-256+Ed25519 chain + embed the BLAKE3 engine witness) is **not** in P1/P3 — both take a dedicated `Signer` (the §8 open question 1 key-ownership decision is unresolved; P3 uses a standalone dev/sensing key precisely so it does not pre-empt P2). P2's `cog-ha-matter` key reuse + BLAKE3-embed, and P4 (multi-modality), remain future work. **No accuracy is claimed** (§0 / §6) — P1/P3 are tested plumbing on a live endpoint + a safe privacy mapping; the live surface is single-link CSI with its existing caveats (no validated room-coordinate accuracy — `field_localize`).
+
+---
+
+## 1. Context — two architectures, mapped
+
+### 1.1 RuField MFS (ADR-260, `vendor/rufield/`)
+
+A standalone pure-Rust Cargo workspace (serde, serde_json, toml, sha2, ed25519-dalek; **no tch/ndarray/candle**), vendored here as a git submodule (`git submodule status vendor/rufield` → `ba66e2e…`), **not** a v2 workspace member — exactly the `vendor/rvcsi` precedent (ADR-095/096). **Not published to crates.io**: every internal dep is a path dep with a nominal `version = "0.1.0"` (`vendor/rufield/Cargo.toml:31-37`); the `docs.rs/rufield-*` URLs are aspirational.
+
+The data model (graded ARCHITECTURE, evidence read directly):
+
+- **`FieldEvent`** (`vendor/rufield/crates/rufield-core/src/event.rs:96-112`): `spec_version, event_id, timestamp_ns: u64, sensor: SensorDescriptor, tensor: FieldTensor, observation: Observation, provenance: ProvenanceRef`.
+- **`Observation`** (`event.rs:25-51`): `zone_id, space_cell, range_m, velocity_mps, motion_vector, confidence: f32, features: BTreeMap<String,f32>` (the derived P1 scalars the fusion engine actually reads), `labels: Vec<String>` (ground-truth, **never read by fusion**), `privacy_class: PrivacyClass`.
+- **`PrivacyClass`** (`rufield-core/src/privacy.rs:8-25`): `P0..P5`, `#[serde(rename_all="UPPERCASE")]`, `Ord` by declaration order so **P0 < P1 < … < P5** — higher = more private; `level()->u8` returns 0..=5 (`privacy.rs:27-40`).
+- **`ProvenanceRef`** (on-wire, `event.rs:73-93`): `raw_hash, firmware_hash` (`sha256:…`), `model_id, calibration_id, synthetic: bool`, optional `signature_hex` / `signer_pubkey_hex` (detached ed25519).
+- The four traits (`rufield-core/src/traits.rs`): **`FieldAdapter`** (`:26-38`, `next_event() -> Result<Option<FieldEvent>>`), **`FieldEncoder`** (`:41-51`, **unimplemented in v0.1** — an open seam), **`FusionEngine`** (`:54-63`, `ingest(event)` + `infer(&query)`), **`PrivacyGuard`** (`:86-97`, `authorize(class, Destination, consent, identity_bound) -> PrivacyDecision{Allow|Deny|RequiresConsent}`).
+- **`CsiReplayAdapter`** (`rufield-adapters/src/csi_replay.rs`): constructed from **already-loaded text** (`from_jsonl(&str)` `:249-251`; `from_jsonl_with(text, device_id, &[u8;32])` `:254-323`) — **not** a path/`Read`/`Iterator`. Deserializes `CsiFrameRecord { timestamp: f64 (seconds), subcarriers: Vec<f64> }` (`:74-80`), buffers all frames into a `Vec<CsiFrame>`, then streams via a cursor (`next_event` `:550-557`). Maps each frame → `FieldEvent` with `Modality::WifiCsi`, axes `[Frequency]`, a Welford motion proxy, observation `privacy_class = P2 if presence else P1` (`:439-443`), real `sha256` raw-hash, and a **real ed25519 signature** (`signer.sign_event` `:507-510`). `max_privacy_class = P2`.
+- **`RuFieldFusion`** (`rufield-fusion/src/engine.rs:55-78`): `ingest()` **rejects non-fusable events on its first line** — `if !is_fusable(&event) { return Err(NotFusable) }` (`:212-215`) — then reads `event.observation.features` into a bounded temporal window; `infer()` applies TOML rules (`WeightedBayes` noisy-OR / `TemporalWindow`) → `Vec<FieldInference>`. TOML rule struct: `inputs, method, feature, threshold, privacy_max, window_ms, requires_consent` (`rules.rs:17-35`).
+- **`is_fusable`** (`rufield-provenance/src/lib.rs:179-184`): `synthetic == true` **OR** `verify_event().is_ok()` — the §11 invariant. Signing key is `ed25519_dalek 2.1`, deterministic from a 32-byte seed; raw hash is `sha256_hex` → `"sha256:<hex>"` (`:26-35`).
+- **`DefaultPrivacyGuard`** (`rufield-privacy/src/lib.rs:38-110`): default `network_max = P2`, `allow_p0_network = false`. P5-no-identity → `Deny`; P4-no-consent → `RequiresConsent`; `EdgeLocal` → `Allow`; `Network` denies P0 and `class > network_max`.
+- **`rufield-viewer`** (Axum 0.7): **self-contained, consumes `SyntheticSim` only** — all routes are read-only GET/SSE (`GET /api/run`, `GET /events`); **there is no ingest endpoint** (`vendor/rufield/crates/rufield-viewer/src/server.rs:63-72`). Feeding it a live stream requires adding a route.
+
+### 1.2 RuView (the integration target)
+
+- **Sensing-server is Axum** (`v2/crates/wifi-densepose-sensing-server/src/main.rs:7498-7629`), two listeners (WS `:8765`, HTTP). CSI does **not** arrive over WS/HTTP — it arrives over **UDP** from ESP32 nodes (`use tokio::net::UdpSocket`, `main.rs:53`; `recv_from` loop `main.rs:5286-5299`), parsed by magic `0xC511_0001` → **`Esp32Frame`** (`types.rs:84-100`: `node_id, n_subcarriers, ppdu_type, amplitudes: Vec<f64>, phases: Vec<f64>`, rssi/freq/sequence) → pushed into per-node `NodeState.frame_history: VecDeque<Vec<f64>>` (`main.rs:441-497`).
+- **`/ws/sensing` emits a `SensingUpdate`** (`main.rs:267-317`), broadcast over a `tokio::sync::broadcast` channel (`s.tx.send(json)` `main.rs:5938-5991`; the WS handler just subscribes and forwards, `main.rs:3021-3073`). `SensingUpdate` carries `nodes`, `features`, `classification {motion_level, presence, confidence}`, `signal_field`, `persons: Vec<PersonDetection>` (17 COCO keypoints + `position:[f64;3]` from `field_localize`, `main.rs:403-428`), pose, vitals. **`field_localize` (PR #1050) is a module, not a route** (`mod field_localize` `main.rs:17`; honesty caveat `field_localize.rs:16-27` — a single ESP32 link cannot resolve true room position, `position` is "strongest field peak").
+- **ruvsense fusion is strictly WITHIN-WiFi-modality.** `MultistaticFuser::fuse(&[MultiBandCsiFrame]) -> FusedSensingFrame` (`v2/crates/wifi-densepose-signal/src/ruvsense/multistatic.rs:285-288`) attention-weights **multiple WiFi CSI nodes/viewpoints** (every input is ESP32 CSI; `multistatic_bridge.rs:50-62` builds the frames from `NodeState` amplitude with `HardwareType::Esp32S3`). `coherence_gate.rs:18-37` is the `GateDecision{Accept|PredictOnly|Reject|Recalibrate}`; `pose_tracker.rs:255-263` is the 17-keypoint Kalman tracker with 128-dim AETHER re-ID; `field_model.rs:301-308` does SVD room-eigenstructure perturbation extraction. **No camera/mmWave/audio enters this path** — ruvsense is a multi-link WiFi-CSI fuser.
+- **The governed-trust cycle** runs in the separate **`wifi-densepose-engine`** crate. `StreamingEngine::process_cycle` (`v2/crates/wifi-densepose-engine/src/lib.rs:409`, `run_cycle` `:434-533`) produces **`TrustedOutput`** (`:82-112`): `semantic_id, quality: QualityScore, effective_class: PrivacyClass, demoted: bool, provenance: SemanticProvenance, witness: [u8;32]` (BLAKE3 over `evidence‖model‖calibration‖privacy_decision‖class`, `witness_of` `:598-613`), `recalibration_recommended`. **Crucially, none of this trust metadata is on the `SensingUpdate` wire today** — it is exposed only out-of-band on `GET /api/v1/status` (`main.rs:4173-4178`) and as a single live effect: `EngineBridge::suppress_raw_outputs()` strips per-node amplitude when `effective_class >= Restricted` (`engine_bridge.rs:240-243`, applied `main.rs:5908-5932`). The honest scope is stated in `engine_bridge.rs:14-27`: the governed engine runs *alongside* the bare fusion path; derived outputs are "published ungoverned."
+
+---
+
+## 2. Decision
+
+1. **Build a thin RuView-side bridge crate `wifi-densepose-rufield`** (a new v2 workspace member) that depends on `vendor/rufield/crates/rufield-core` (+ `rufield-provenance`, `rufield-privacy`, `rufield-fusion`) **via path** — mirroring the `vendor/rvcsi` pattern. RuView does **not** depend on published rufield crates (there are none) and does **not** vendor rufield into the v2 workspace; rufield stays a standalone submodule and the bridge is the only coupling point (an anti-corruption layer).
+2. **Emit `FieldEvent`s from the live server via an in-process `SensingServerAdapter`**, not by re-using the file-based `CsiReplayAdapter` on the hot path. The bridge taps the existing `SensingUpdate` build site and the `EngineBridge` trust state, joins them, and emits one signed `FieldEvent` per cycle on a new `tokio::broadcast` topic / optional `/ws/field` endpoint. `CsiReplayAdapter` is retained for the **offline/replay** path (recorded `.csi.jsonl` → events) because it already reads RuView's recording format (`recording.rs` writes `{session}.csi.jsonl`).
+3. **Compose the two fusion engines vertically, do not merge them.** ruvsense stays the **WiFi-modality node** (multi-link fusion → one fused WiFi belief); rufield-fusion sits **above** it as the **cross-modality** graph. ruvsense's `FusedSensingFrame`/`TrustedOutput` becomes one `FieldEvent` (modality `wifi_csi`); rufield fuses it against future mmWave/thermal/`rvcsi` events. They do not conflict because ruvsense has no cross-modality fusion to collide with (§1.2 evidence).
+4. **Reconcile privacy/provenance with ONE canonical model + a documented mapping** (§3, the crux): RuView's `effective_class` is the **source of truth**, mapped onto RuField `PrivacyClass` at the bridge; RuView's existing **`cog-ha-matter` SHA-256+Ed25519 witness chain** (already RuField's exact crypto) is adopted as the carrier for RuField `ProvenanceReceipt`, with the live BLAKE3 engine witness embedded as a hashed field. We do **not** maintain two parallel signed-receipt systems.
+
+---
+
+## 3. Privacy & provenance reconciliation (the crux)
+
+This is the most important section. RuView and RuField genuinely **overlap and partially conflict**. We map both honestly.
+
+### 3.1 What RuView actually has (implemented, with evidence)
+
+- **TWO privacy enums, not one ladder.** `PrivacyClass` — **4 variants** `Raw=0, Derived=1, Anonymous=2, Restricted=3` (`v2/crates/wifi-densepose-bfld/src/lib.rs:103-116`, `#[repr(u8)]`, higher byte = more private, **non-monotonic in information** — `Derived=1` carries *more* identity than `Anonymous=2`). And `PrivacyMode` — **5 variants** `RawResearch, PrivateHome, EnterpriseAnonymous, CareWithConsent, StrictNoIdentity` (`bfld/src/privacy_mode.rs:18-31`), each mapping to a `PrivacyClass` via `target_class()` (`:63-70`; two modes collapse to `Anonymous`).
+- **THREE witness mechanisms across TWO hash algorithms:**
+  - BFLD `PrivacyAttestationProof` — **BLAKE3, unsigned**, attests mode/class continuity only; **built but NOT on the live path** (ADR-141 status line ~597; `bfld/src/privacy_mode.rs:121-148`).
+  - Engine-cycle `TrustedOutput.witness: [u8;32]` — **BLAKE3, unsigned**, over the full trust decision; **LIVE every cycle** (`wifi-densepose-engine/src/lib.rs:598-613`).
+  - `cog-ha-matter::WitnessChain` — **SHA-256 hash chain + Ed25519 signatures** (`v2/crates/cog-ha-matter/src/witness.rs:138-151`; `witness_signing.rs:39-76`), JSONL-persisted, `verify()` + `verify_signature()`. Implemented for ADR-116 (cog/Matter audit log); **standalone, not wired to BFLD/engine**. Its `WitnessHash` newtype doc explicitly anticipates a hash-algo migration (`witness.rs:37-41`).
+- **No numeric trust score.** "Trust" in code = `base_coherence: f32∈[0,1]` + `penalized_coherence()` (`signal/.../fusion_quality.rs:99,122-126`) + a **boolean** `forces_privacy_demotion()` (`:116`). Demotion is monotonic and irreversible (`demote_one` clamps at Restricted, `engine/src/lib.rs:617-619`).
+- **Structured provenance exists, but no signed "receipt" on the sensing path.** `SemanticProvenance { evidence, model_version, calibration_version, privacy_decision }` (`v2/crates/wifi-densepose-worldgraph/src/model.rs:137-147`) is attached to every belief and is the *input* to the BLAKE3 witness — but it is unsigned and not called a receipt.
+
+### 3.2 Side-by-side, graded
+
+| Dimension | RuView (file:line) | RuField | Alignment |
+|---|---|---|---|
+| Privacy ladder | `PrivacyClass` 4 (`bfld/lib.rs:103`) **or** `PrivacyMode` 5 (`bfld/privacy_mode.rs:18`) | `PrivacyClass` 6 (P0–P5, `rufield-core/privacy.rs:8`) | **PARTIAL→CONFLICT** — no clean 1:1; counts differ (4/5 vs 6); RuView class ordering non-monotonic |
+| Demotion direction | higher = more private, irreversible (`engine/lib.rs:617`) | higher P# = more private, `Ord` by decl order (`privacy.rs:8-25`) | **STRONG** (same direction) |
+| Provenance receipt | `SemanticProvenance` unsigned (`worldgraph/model.rs:137`) | `ProvenanceRef` + ed25519 (`event.rs:73`) | **PARTIAL** — structured but unsigned |
+| Witness crypto (live path) | BLAKE3 `[u8;32]`, unsigned (`engine/lib.rs:598`) | sha256 + ed25519 (`rufield-provenance/lib.rs:26,135`) | **CONFLICT** (algo + signing) |
+| Witness crypto (cog-ha-matter) | **SHA-256 + Ed25519** (`cog-ha-matter/witness.rs`, `witness_signing.rs`) | **sha256 + ed25519** | **STRONG** — RuField's exact crypto, already in-repo, but unwired and in another bounded context |
+| Trust / confidence | `penalized_coherence: f32` + boolean demote (`fusion_quality.rs:122`) | `confidence: f32` per observation | **WEAK** — RuView has no graded trust object; confidence maps, demotion is binary |
+
+### 3.3 The recommendation (the key call)
+
+**Adopt ONE canonical model with a documented, lossy-but-monotonic mapping — do not run two parallel schemes.** Concretely:
+
+1. **Privacy: RuView `effective_class` is the source of truth; the bridge maps it onto RuField `PrivacyClass`** at the egress boundary. The honest mapping (graded ARCHITECTURE — it is a *policy* decision, and it is **monotonicity-testable**, not an accuracy claim):
+
+   | RuView `PrivacyClass` | → RuField | Rationale |
+   |---|---|---|
+   | `Raw` (raw CSI amplitude) | `P0` | raw waveform |
+   | `Derived` (identity embedding, LAN-only) | `P4` *(or P5 if identity-bound)* | derived **identity** features ⇒ biometric/identity tier, **not** P1 — RuView's non-monotonic `Derived=1` is the trap; map by *information content*, not byte value |
+   | `Anonymous` (occupancy/aggregate) | `P2`/`P3` | occupancy → P2, room-count aggregate → P3 |
+   | `Restricted` (zeroized) | `P2`-capped, raw suppressed | matches `suppress_raw_outputs` (`engine_bridge.rs:240`) |
+
+   The bridge **must** map `Derived → P4/P5`, never P1, because RuView's `Derived` carries `identity_embedding` (§3.1) — this is the single most dangerous mapping mistake and gets a dedicated test (P2 in §4). `PrivacyMode` (5) is the better *operator-facing* join to RuField's 6 levels but the **class** is what gates egress, so the class mapping is canonical.
+
+2. **Provenance: adopt `cog-ha-matter`'s SHA-256+Ed25519 chain as the carrier for RuField `ProvenanceReceipt`** — it is already RuField's exact crypto (graded STRONG above), already implemented, already tamper-evident. The bridge constructs the RuField `ProvenanceRef` by: `raw_hash = sha256(csi bytes)`, `model_id`/`calibration_id` from `SemanticProvenance`, and **embeds the live BLAKE3 engine witness `[u8;32]` as a hashed provenance field** (it is already computed every cycle — do not throw it away), then **signs with ed25519** so `is_fusable` passes for live (non-synthetic) events. We do **not** add a second BLAKE3-vs-ed25519 argument: BLAKE3 stays RuView's internal fast cycle-fingerprint; ed25519 is the *external* attestation RuField requires. One signer, one chain.
+
+3. **Trust: map `penalized_coherence` → `Observation.confidence`; keep demotion binary.** RuView has no graded trust object to reconcile; the coherence scalar is the honest analog and the demotion boolean already drives `effective_class`.
+
+This is a **bridge-with-canonical-source**, not "keep both forever." RuView owns the privacy decision (it has the live governed cycle); RuField owns the *external wire shape* (P0–P5 + signed receipt). The bridge is the one-directional translation, and it is the only place the two schemes meet.
+
+---
+
+## 4. Phased plan (each phase independently shippable + testable)
+
+**P1 — `SensingServerAdapter` emitting `FieldEvent`s (ARCHITECTURE).**
+New crate `wifi-densepose-rufield` with a `SensingServerAdapter` that consumes a `(SensingUpdate, TrustedOutput)` pair (tapped at `main.rs:5886`/`:5938`) and emits a signed `FieldEvent` (`Modality::WifiCsi`, axes `[Frequency]`, observation features from `SensingUpdate.features`, `confidence` from `penalized_coherence`). Offline path: keep `CsiReplayAdapter` for recorded `.csi.jsonl`. **Gate:** a round-trip test — emit a `FieldEvent` from a fixture `SensingUpdate`, assert it serializes, `is_fusable` passes (ed25519-signed), and `RuFieldFusion::ingest` accepts it. No server changes required beyond exposing the tap; the adapter is a library.
+
+**P2 — privacy/provenance bridge (the crux, ARCHITECTURE).**
+Implement the §3.3 mapping: `effective_class → PrivacyClass`, `cog-ha-matter` ed25519 signer for the receipt, BLAKE3 witness embedded. **Gates (three, all monotonicity/safety, not accuracy):** (a) `Derived → P4|P5` never P1 (the dangerous-mapping test); (b) privacy monotonicity — `demoted == true` ⇒ emitted `PrivacyClass >= P2` and raw suppressed; (c) signature round-trip — sign with the cog-ha-matter key, `rufield_provenance::verify_event` passes. This phase is shippable without P3 (events emitted on an internal topic, not yet on the public wire).
+
+**P3 — surface in `/ws` + viewer (ARCHITECTURE).**
+Add an opt-in `/ws/field` endpoint (or a `field_events` array on `SensingUpdate` behind a flag) carrying the signed `FieldEvent` + a privacy badge. Add an ingest route to `rufield-viewer` (it has none today — `server.rs:63-72`) so it can replay RuView's live feed instead of only `SyntheticSim`. **Gate:** a WS integration test asserting a connected client receives a privacy-badged, signature-verifiable `FieldEvent`; a viewer test asserting the new ingest route renders a live event. The `cognitum` appliance can speak RuField by consuming this endpoint (it already runs `ruview-vitals-worker`); deferred to its own ADR.
+
+**P4 — fusion composition + multi-modality (ARCHITECTURE, optional).**
+Wire a second modality (cheapest: an `rvcsi`-sourced event, or recorded mmWave) into `RuFieldFusion` alongside the WiFi event, proving cross-modality fusion above ruvsense. **Gate:** a fusion test with two modalities producing ≥1 cross-modal inference, with provenance coverage 100%.
+
+---
+
+## 5. Decision matrix
+
+### 5.1 Data-path emission (P1)
+
+| Option | Latency | Reuse | Live-fit | Risk | Verdict |
+|---|---|---|---|---|---|
+| Re-use `CsiReplayAdapter` on hot path | poor (file buffer, `&str` ctor) | high | **bad** — it's a file-cursor, not a live source | low | **Reject for live** (keep for replay) |
+| In-process `SensingServerAdapter` (tap `SensingUpdate`+`TrustedOutput`) | good | medium | **good** — taps the real emit + real trust state | low | **CHOSEN** |
+| Server publishes `FieldEvent` on its own topic (no adapter trait) | good | low | good | medium (bypasses `FieldAdapter` contract) | Reject — loses the trait seam |
+
+### 5.2 Fusion relationship (P3/P4)
+
+| Option | Verdict |
+|---|---|
+| Merge ruvsense into rufield-fusion | **Reject** — different scopes; ruvsense is within-WiFi multi-link, rufield is cross-modality |
+| rufield-fusion wraps ruvsense (vertical compose) | **CHOSEN** — ruvsense → one WiFi `FieldEvent` → rufield cross-modality graph |
+| Run both as peers, reconcile after | Reject — duplicates fusion semantics, two contradiction models |
+
+### 5.3 Privacy/provenance reconciliation (P2)
+
+| Option | Verdict |
+|---|---|
+| (a) Map RuView classes onto RuField P0–P5, RuView canonical | **CHOSEN (privacy)** — `effective_class` is the live source of truth |
+| (b) Adopt RuField ed25519 receipts as RuView's provenance | **CHOSEN (provenance)** — via the already-present `cog-ha-matter` SHA-256+Ed25519 chain |
+| (c) Keep both schemes with a permanent bridge | **Reject** — two signed-receipt systems is the duplication we must not ship |
+
+### 5.4 Dependency direction
+
+| Option | Verdict |
+|---|---|
+| Depend on published rufield crates | **Reject** — not published (`vendor/rufield/Cargo.toml:31-37`) |
+| Make rufield a v2 workspace member | **Reject** — breaks the standalone-spec/`rvcsi` precedent |
+| Thin `wifi-densepose-rufield` bridge → path deps on submodule | **CHOSEN** — anti-corruption layer, single coupling point |
+
+---
+
+## 6. Security & honesty notes
+
+- **No accuracy claim.** Live RuField events from RuView are derived from the same single-link CSI whose own caveats are on record (`field_localize.rs:16-27`); the offline path is unlabeled replay (`csi_replay.rs:19-31`). This ADR ships **plumbing with monotonicity/signature gates**, not validated F1.
+- **The dangerous mapping is `Derived → P1`.** RuView's `Derived` byte value (1) is numerically below `Anonymous` (2) but carries identity (`bfld/lib.rs`); a naive byte-mapping would leak identity-bearing features as low-privacy P1. P2's gate (a) exists specifically to prevent this.
+- **One signer, not two.** Adding a second ed25519 keypair alongside `cog-ha-matter`'s would create two roots of trust. The bridge reuses the cog-ha-matter signing key (`witness_signing.rs`).
+- **`is_fusable` is a real gate, not decoration** (`rufield-provenance/lib.rs:179-184`): live events that fail to sign are rejected by `RuFieldFusion::ingest` — we must not paper over a signing failure with `synthetic = true` on a real event (that would be the §11 invariant violation the spec forbids).
+- BLAKE3 stays internal; ed25519 is the external attestation. We do not relitigate RuView's BLAKE3 cycle-witness — it is embedded, not replaced.
+
+## 7. Consequences
+
+**Positive:** RuView becomes one honest adapter in the larger RuField ecosystem (ADR-260 goal §9) without forking its fusion or privacy engine; the three witness mechanisms get a single external attestation path; cross-modality fusion becomes possible above the existing WiFi fusion; the `cognitum` appliance gains a standard wire format. The bridge is the only coupling point, so rufield can evolve as a standalone spec.
+
+**Negative:** a fourth crate to maintain; the privacy mapping is lossy (4/5 → 6) and must be kept honest by tests; reusing the `cog-ha-matter` key crosses a bounded-context boundary (cog/Matter ↔ sensing) that ADR-116 kept separate — that coupling needs review. The live trust metadata (`witness`, `effective_class`) is **currently decoupled** from `SensingUpdate` (§1.2), so P1 must do real join work, not a field read.
+
+## 8. Open questions
+
+1. **Signer ownership:** should the bridge reuse the `cog-ha-matter` Ed25519 key, or mint a dedicated RuView-sensing key with its own rotation? (Reuse couples bounded contexts; a new key adds a second root of trust.)
+2. **`PrivacyMode` vs `PrivacyClass` as the canonical map target:** class gates egress (chosen), but the 5-mode ladder is the cleaner join to 6 levels — do we expose mode in the receipt too?
+3. **Where does the BLAKE3 engine witness live in the RuField receipt** — a `firmware_hash`-style field, an extension field, or a `CalibrationReceipt.data_hash`? (RuField's `ProvenanceRef` has no spare slot; needs a spec extension or reuse of `model_id`.)
+4. **Should `field_localize` positions ride in `Observation.space_cell`/`motion_vector`** given the explicit single-link caveat, or stay RuView-only until multi-node calibration lands?
+5. **`rvcsi` relationship:** `rvcsi` has its own `CsiFrame`/`CsiWindow` and could implement `FieldAdapter` directly — should the second modality in P4 be `rvcsi`, making RuField the convergence point for *both* vendored sensing runtimes?
+6. **Transport:** RuField ADR-260 §29 leaves default transport open (MQTT/NATS/WS/MCP). RuView is WS + UDP + broadcast; does `/ws/field` suffice, or does the appliance need MQTT to match the cog stack?
+
+## 9. Recommendation
+
+Proceed with P1+P2 behind a feature flag. They are independently shippable, carry real gates (round-trip, monotonicity, signature-verify), and require no change to RuView's fusion or privacy engine — only a tap and a translation. Defer P3/P4 and the appliance/transport questions to follow-up ADRs once the bridge round-trips on recorded `.csi.jsonl` and on one live cycle.

+# SOTA Evidence Brief — `wifi-densepose-nn` / `wifi-densepose-train` Benchmark ADR Seed
+
+| Field | Value |
+|-------|-------|
+| **Date** | 2026-06-14 |
+| **Author** | deep-research (Opus) |
+| **Purpose** | Seed a future benchmark/optimization ADR for the NN-inference (`wifi-densepose-nn`) and training (`wifi-densepose-train`) crates |
+| **Scope** | The DELTA beyond what ADR-152 / ADR-150 / ADR-015 already establish — current published WiFi-CSI pose SOTA, winning architectures, edge-quantization SOTA, and a defensible benchmark-suite design |
+| **Ethos** | Every claim graded PEER-REVIEWED / PREPRINT / VENDOR-CLAIM / BLOG, with MEASURED-on-public-benchmark distinguished from marketing. Numbers that could not be verified are flagged. No fabricated citations. |
+
+> **Citation discipline carried in from ADR-152 §2.2:** preprint accuracy numbers are CLAIMED until reproduced on our hardware. The project has already retracted its own "92.9% PCK@20" and "shipped-WiFlow-STD 97.25%" figures after measurement; this brief inherits that bar.
+
+---
+
+## 1. Executive summary
+
+**Where the project stands vs the 2026 frontier.** The repo is, by the evidence already in-tree, *ahead of most academic groups on benchmark hygiene* and roughly *at parity on capability* — but the two are measured on incompatible yardsticks, which is the single biggest risk to any "beyond-SOTA" claim.
+
+- The project's headline reproductions (`benchmarks/wiflow-std/RESULTS.md`) are MEASURED and rigorous: WiFlow-STD retrained to **96.09–96.61% PCK@20** on the authors' own 360k-window 2D dataset (RTX 5080), shipped checkpoint REFUTED, dataset/code defects documented. This is a genuinely strong, reproducible result.
+- **But that number is not on a standard public benchmark.** WiFlow-STD's dataset is self-collected (5 subjects, 15 keypoints, 2D, in-domain random split, hardware unspecified). The academic frontier on the *standard* public 3D benchmark (MM-Fi) reports **PCK@20 ≈ 61% / MPJPE ≈ 161 mm random-split** (GraphPose-Fi, Nov 2025) — a *harder* metric (3D, mm-scale, standard PCK normalization). The project's own AetherArena MM-Fi number (**81.63% torso-PCK@20 in-domain**, ADR-150) uses a *torso-normalized PCK* that is looser than GraphPose-Fi's standard PCK, so the three numbers (96% / 81.6% / 61%) **cannot be lined up** without a unified harness. Making them comparable IS the highest-value work item.
+- The deployment frontier — **cross-subject / cross-environment generalization** — is where everyone collapses, the project included (ADR-150: 81.63% in-domain → ~11.6% leakage-free cross-subject). GraphPose-Fi independently confirms the cliff (61.1% random → 12.9% cross-environment PCK@20). This is the real research target, not in-domain PCK.
+
+**Top 3 highest-value optimization/benchmark targets:**
+
+1. **A unified, metric-locked accuracy harness in `wifi-densepose-train`** that scores any model under *one* explicit PCK definition (normalization, keypoint convention, split) so WiFlow-STD-repro, AetherArena/MM-Fi, and GraphPose-Fi numbers become directly comparable. Without this, no "beyond-SOTA" claim survives the "prove it" bar — the project has already been burned twice by metric ambiguity (the retracted 92.9% used absolute, not torso-normalized, PCK).
+2. **A QAT path for the WiFlow-STD-class edge model.** The in-tree edge work (`RESULTS.md`) has *fully characterized PTQ* (static QDQ conv-only is the int8 sweet spot; dynamic int8 is a no-op on this all-conv architecture) and found the **half model (843k params) strictly dominates the published 2.23M** and **tiny (56k, 295 KB ONNX fp32) holds 94.1% PCK@20**. The one untested lever is **quantization-aware training**, which the general literature says recovers most of the PTQ accuracy gap. That is the next defensible edge win.
+3. **Criterion-backed regression benches wired into CI** for the real Candle/ONNX forward path. The benches *exist* (`wifi-densepose-nn/benches/{inference,onnx,native_conv}_bench.rs`, `wifi-densepose-train/benches/training_bench.rs`) and `benchmarks/edge-latency/RESULTS.md` shows the methodology is sound (host≠ESP32 caveat made explicit). The gap is turning point-in-time captures into committed regression baselines.

+
+## 2. Findings per research question
+
+### RQ1 — Latest WiFi-CSI pose SOTA (2024–2026): published PCK@20 / MPJPE on the standard public benchmarks
+
+The crucial framing: **"WiFi pose SOTA" splits into two non-comparable tracks** — 3D pose on MM-Fi/Person-in-WiFi-3D (mm-scale MPJPE, standard PCK) vs 2D pose on self-collected sets (image-normalized PCK). The project's flagship reproduction lives in the second track; the academic frontier lives in the first.
+
+| Method | Venue / Year | Benchmark + split | PCK@20 | MPJPE | Grade |
+|---|---|---|---|---|---|
+| **GraphPose-Fi** (arXiv [2511.19105](https://arxiv.org/abs/2511.19105)) | PREPRINT, Nov 2025 | MM-Fi P1, **random split** | **61.1%** | **160.6 mm** (PA-MPJPE 105.0) | numbers MEASURED-in-study (preprint); beats MetaFi++, HPE-Li, DT-Pose |
+| GraphPose-Fi | same | MM-Fi P1, **cross-subject** | 44.2% | 210.5 mm | same |
+| GraphPose-Fi | same | MM-Fi P1, **cross-environment** | 12.9% | 302.7 mm | same — the generalization cliff |
+| **DT-Pose** (arXiv [2501.09411](https://arxiv.org/abs/2501.09411)) | PREPRINT (ICLR'25 OpenReview [aPnLQ6WfQQ](https://openreview.net/forum?id=aPnLQ6WfQQ)), Jan 2025; code [cseeyangchen/DT-Pose](https://github.com/cseeyangchen/DT-Pose) | MM-Fi (domain-gap + topology focus) | not cleanly extractable from abstract | reports MPJPE; self-supervised masked pretrain + topology decode | numbers NOT verified at exact-table level here — flagged |
+| **Person-in-WiFi-3D** (CVPR 2024, [openaccess](https://openaccess.thecvf.com/content/CVPR2024/html/Yan_Person-in-WiFi_3D_End-to-End_Multi-Person_3D_Pose_Estimation_with_Wi-Fi_CVPR_2024_paper.html)) | **PEER-REVIEWED**, CVPR 2024 | own 97k-frame multi-person set | — (multi-person, not single-PCK) | **91.7 mm (1p) / 108.1 (2p) / 125.3 (3p)** 3D joint error | MEASURED (peer-reviewed); own dataset, not MM-Fi |
+| **WiFlow-STD** (arXiv [2602.08661](https://arxiv.org/abs/2602.08661), [DY2434 repo](https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling)) | PREPRINT, Apr 2026 | self-collected, 5-subj, **2D, in-domain random** | 97.25% (claimed) | 0.007 m (image-norm) | claimed CLAIMED; **project reproduced 96.09–96.61% (MEASURED, RTX 5080)** after repairing dataset/code |
+| **PerceptAlign** (arXiv [2601.12252](https://arxiv.org/abs/2601.12252)) | PREPRINT + MobiCom'26 acceptance | own 7-layout cross-domain 3D set | — | 222.4 mm (Scene4) / 317.1 (Scene5), claims −54% cross-env vs SOTA | CLAIMED (preprint); failure mode corroborated |
+| **Project AetherArena** (ADR-150, [issue #876](https://github.com/ruvnet/RuView/issues/876)) | internal | MM-Fi, **random split**, **torso-PCK** | **81.63% torso-PCK@20** | — | MEASURED-internal; **torso-PCK ≠ GraphPose-Fi standard PCK** |
+| **Project WiFlow-STD repro** (`benchmarks/wiflow-std/RESULTS.md`) | internal | their data, their split | **96.09–96.61%** | 0.0094–0.0098 m | MEASURED-internal (RTX 5080) |
+
+**How the project's ~96% compares to the frontier:** It is *not directly comparable*. The 96% is on an easier task (2D, in-domain, image-normalized PCK, single-environment, 5 subjects) than GraphPose-Fi's 61.1% (3D, standard PCK, mm-scale). The project's own MM-Fi-track number (81.63% torso-PCK@20) *appears* to beat GraphPose-Fi's 61.1%, **but only because torso-PCK is a looser normalization** — the project explicitly flags this (ADR-150 cites beating "MultiFormer's 72.25%" under the *same* torso metric, not GraphPose-Fi's). The honest statement: **the project is competitive on in-domain MM-Fi under its own torso metric, and collapses cross-subject exactly as the published frontier does.** No public number lets the project claim "beyond-SOTA" today.
+
+### RQ2 — What's winning architecturally now (2025–2026)
+
+The clear trend across the verified 2025–2026 papers:
+
+- **Graph / skeleton-aware decoders are the current academic SOTA on MM-Fi.** GraphPose-Fi (PREPRINT, Nov 2025) wins by injecting anatomical graph structure into the decoder — exactly the `GraphPose-Fi-style skeleton-aware graph head` ADR-150 §2.2 already names as the planned decoder. *The project's architecture direction matches the frontier.*
+- **Self-supervised masked pretraining (MAE) is the cross-domain lever, not capacity.** UNSW MAE study (arXiv [2511.18792](https://arxiv.org/abs/2511.18792), PREPRINT, Nov 2025): cross-domain gains scale **log-linearly with pretraining data, unsaturated at 1.3M samples**; ViT-Base adds only 0.4–0.9% over ViT-Small. Recipe: **80% masking, (30,3) small patches**. DT-Pose (arXiv 2501.09411) independently uses masked pretraining + topology constraints for the domain gap. *Caveat (MEASURED in ADR-152 §2.3): UNSW's downstream tasks are classification, not pose — pose transfer remains a hypothesis. The project's own measurement (b) found WiFlow-STD pretrained features give optimization transfer but NOT feature transfer to ESP32 CSI.*
+- **Spatio-temporal decoupling is the efficiency lever.** WiFlow-STD's whole contribution is decoupling spatial and temporal CSI processing to hit 2.23M params. The project verified the params/FLOPs (MEASURED) and then **beat it**: the half-model (843k) matches accuracy with 0.38× params (`RESULTS.md` efficiency sweep).
+- **Geometry/layout conditioning is the cross-layout lever.** PerceptAlign (MobiCom'26): fusing transceiver-position embeddings + two-checkerboard calibration, claimed −60% cross-domain. ADR-152 §2.1 already adopted this (`NodeGeometry`, geometry embeddings).
+- **NOT winning / absent:** diffusion models for CSI pose did not surface in the verified frontier. Full DensePose-UV regression from commodity WiFi remains undemonstrated (ADR-152 F5, MEASURED by full-text screening). No 2025–2026 paper was found that *beats the project's current direction* — the project is tracking, not trailing, the architecture frontier.
+
+**Verdict RQ2:** the winning stack (MAE pretrain → graph/skeleton decoder → geometry conditioning, ViT-Small-class capacity) is *already the planned ADR-150/152 stack*. The gain available is not a new architecture; it's (a) more heterogeneous pretraining data and (b) honest cross-domain measurement.
+
+### RQ3 — Edge/quantized inference SOTA for small CSI pose models
+
+The in-tree edge work (`benchmarks/wiflow-std/RESULTS.md` "Edge optimization" + "Static PTQ" + "Efficiency sweep") is already at or beyond what the public literature offers for this specific model class, and is MEASURED. Key findings to carry forward:
+
+- **Dynamic INT8 is a trap on all-conv CSI models.** WiFlow-STD has **zero `nn.Linear` layers** (21 Conv1d + 22 Conv2d + BatchNorm). `torch.quantize_dynamic` quantizes 0% of params (dynamic int8 has no conv kernels). MEASURED.
+- **Static QDQ conv-only PTQ is the int8 sweet spot.** PCK@20 96.60–96.63% (vs fp32 96.68%, dynamic 96.52%), 2.53 MB. All-ops QDQ is strictly worse (−1.4 pt). MEASURED.
+- **ONNX Runtime fp32 is the real CPU latency win**: 3.2 ms/window batch-1 vs torch 11.0 ms (~3.4×) at parity (2.4e-7). int8 is ~2× *slower* than ONNX fp32 at batch-1 (ConvInteger kernels). MEASURED.
+- **Smaller-than-published dominates.** half (843k) ≥ full on accuracy; **tiny (56k, 295 KB ONNX fp32, 0.66 ms/win, 94.1% PCK@20)** is the smallest deployable artifact. At tiny scale int8 is a *bad* trade (−1.43 pt for −47 KB). MEASURED.
+- **General QAT-vs-PTQ context (BLOG/VENDOR):** [NVIDIA TensorRT QAT blog](https://developer.nvidia.com/blog/achieving-fp32-accuracy-for-int8-inference-using-quantization-aware-training-with-tensorrt/), [Ultralytics QAT glossary](https://www.ultralytics.com/glossary/quantization-aware-training-qat), [ONNX Runtime quantization docs](https://onnxruntime.ai/docs/performance/model-optimizations/quantization.html): QAT "almost always" recovers accuracy PTQ loses on sensitive models; ONNX Runtime does NOT retrain (QAT must happen in PyTorch, then export QDQ). The [Onboard Optimization survey, arXiv 2505.08793](https://arxiv.org/pdf/2505.08793) (PREPRINT) covers on-device optimization broadly. These are *general* claims, not CSI-pose-specific — grade accordingly.
+- **Hailo / Pi target (CLAUDE.local.md):** the 4× Pi+Hailo cluster (Hailo-8 @ 26 TOPS / Hailo-10 @ 40 TOPS) needs a **HEF** compile path, which is its own toolchain (not ONNX/Candle). No in-tree HEF benchmark exists yet — this is a genuine gap for the edge-inference claim.
+
+**Actionable for an inference-speed benchmark:** the honest comparand set is `{torch fp32, ONNX fp32, ONNX static-QDQ-conv-only int8, candle fp32}` × `{full, half, tiny}` on a fixed host, with the **host≠ESP32 / host≠Hailo caveat stated up front** (the `edge-latency/RESULTS.md` template already does this correctly). The one new datapoint worth producing: **QAT-int8 on the half model** to test whether QAT closes the PTQ −0.16 pt gap *and* keeps the size win.
+
+### RQ4 — Rigorous, reproducible benchmark methodology
+
+The repo already demonstrates the right methodology in three places — the ADR should codify it, not invent it:
+
+- **`benchmarks/wiflow-std/RESULTS.md`** — the gold standard already in-tree: pinned upstream commit, seed-42 file-level split documented, corruption masks committed as ground truth, every forced deviation recorded, mean-pose honesty baseline, MEASURED-vs-CLAIMED grading.
+- **`benchmarks/edge-latency/RESULTS.md`** — criterion 0.5, explicit host machine, low/median/high brackets, contention caveat, host≠ESP32 separation, steady-state-vs-cold-start distinction.
+- **Rust micro-bench:** criterion benches already exist in both crates (`wifi-densepose-nn/benches/`, `wifi-densepose-train/benches/`).
+
+What a credible "beyond-SOTA" claim requires (the bar that survives "prove it"):
+1. **One locked accuracy definition** — PCK normalization (torso vs absolute vs bbox), keypoint convention (15 vs 17 COCO), and split (random / cross-subject / cross-environment) declared *before* the run. The retracted 92.9% died exactly because PCK normalization was unstated.
+2. **A mean-pose / constant-output honesty baseline** on every split (already done in measurement (b) — a single-subject near-static set scored 95.9% torso-PCK@20 with a *constant* pose). Any claim must beat this.
+3. **MEASURED-vs-CLAIMED grading** per number, with the exact command and raw-JSON path committed.
+4. **Cross-domain, not just in-domain.** In-domain PCK is saturated and uninformative; the defensible claim is on cross-subject/cross-environment, where the frontier is 12–44% PCK@20.
+
+---
+
+## 3. Proposed benchmark-suite design
+
+A two-part suite (`wifi-densepose-train` accuracy harness + `wifi-densepose-nn` latency harness), both committing raw JSON + a graded RESULTS.md.
+
+### 3.1 Accuracy harness (`wifi-densepose-train`)
+
+- **Metric module with one canonical PCK** (parameterized: `{torso, bbox, absolute}` normalization × threshold × keypoint-map), so a single function scores WiFlow-STD-repro, MM-Fi/AetherArena, and a GraphPose-Fi re-run identically. Lock the default to **torso-PCK@20 on 17-kp COCO** and *always* also print standard-PCK to expose the gap.
+- **Fixed datasets/splits:** (i) WiFlow-STD cleaned 360k (their split, for repro parity), (ii) MM-Fi P1 random + cross-subject + cross-environment (to line up against GraphPose-Fi 61.1/44.2/12.9 and the project's 81.63), (iii) ESP32 paired eval set when ≥2k multi-subject windows exist.
+- **Mandatory honesty baselines** emitted every run: mean-pose, constant-output, and (for cross-domain) source-only.
+- **Output:** raw JSON + a RESULTS.md table with MEASURED/CLAIMED grades, mirroring `benchmarks/wiflow-std/RESULTS.md`.
+
+### 3.2 Latency/size harness (`wifi-densepose-nn`)

+- **Matrix:** `{torch fp32 (ref), ONNX fp32, ONNX static-QDQ-conv-only int8, candle fp32}` × `{full 2.23M, half 843k, tiny 56k}` × `{batch 1, 64}`, criterion-timed, host declared.
+- **Report:** disk size, batch-1 + batch-64 ms/window (median + low/high), and PCK@20 on the locked 10k-window subset, so latency and accuracy never get cited apart.
+- **Caveat block up front:** host ≠ ESP32-S3/WASM3, host ≠ Hailo HEF. No host number is presented as the edge number.
+- **CI gate:** commit the current medians as regression baselines; fail PRs that regress latency >X% or accuracy >Y pt.
+
+### 3.3 What counts as a defensible "beyond-SOTA" result
+
+A claim is citable only if **all** hold: (1) scored under a pre-declared metric/split, (2) beats the relevant published frontier number *on the same metric definition* (e.g. >61.1% standard-PCK@20 on MM-Fi random, or >12.9% on cross-environment), (3) beats the mean-pose honesty baseline, (4) raw JSON + exact command committed, (5) graded MEASURED. The single most valuable "beyond-SOTA" target is **cross-environment MM-Fi**, where the published bar (12.9% PCK@20) is low enough that a real win is both achievable and unambiguous.

+
+### RuField surface (ADR-262 P3)
+
+RuView's live WiFi-CSI sensing now also speaks the standalone **RuField MFS** wire format. Each governed sensing cycle is converted (via the `wifi-densepose-rufield` anti-corruption bridge) into a **signed** `FieldEvent` (`Modality::WifiCsi`, ed25519 `ProvenanceRef`) and surfaced on two additive endpoints:
+
+- `GET /api/field` — the most recent signed events (JSON).
+- `GET /ws/field` — a WebSocket that streams each cycle's signed event (mirrors `/ws/sensing`).
+
+```bash
+curl -s http://localhost:3000/api/field | python -m json.tool          # latest signed FieldEvents
+python -c "import asyncio,websockets; asyncio.run((lambda: websockets.connect('ws://localhost:8765/ws/field'))())"  # stream
+```
+
+Privacy is fail-closed: only egress-safe **P1/P2** events leave the box — raw (P0) and identity/biometric/aggregate (P3–P5) cycles are held **edge-local** and never appear on these endpoints; a no-presence cycle emits **no event**.
+
+**Signing key:** the surface signs with a **dedicated dev/sensing key**, seeded from `WDP_RUFIELD_SIGNING_SEED` (a 64-char hex string or a ≥32-byte value); when unset it falls back to a deterministic dev default and logs a `WARN` (the `dev_signing_key` flag in `/api/field` reflects this). This is a standalone key pending the ADR-262 §8 Q1 key-ownership decision — set `WDP_RUFIELD_SIGNING_SEED` for any real deployment.
+
+> **Honesty (ADR-262 §0/§6):** this is real plumbing on a live endpoint, **not an accuracy claim.** It is the single-link CSI sensing with its existing caveats (no validated room-coordinate accuracy — positions are the "strongest field peak", not calibrated triangulation).

+ *
+ * Covers two pure decision functions extracted from edge_processing.c:
+ *   1. count_distinct_persons()  — issue #998 person over-count gate
+ *                                   (energy gate + spatial dedup).
+ *   2. person_count_debounce()   — issue #998 count persistence debounce.
+ *   3. presence_flag_update()    — issue #996 presence hysteresis + clear
+ *                                   debounce (Schmitt trigger).
+ *
+ * Build (Linux/macOS/Windows with any C99 compiler):
+ *   cc -std=c99 -Wall -I../main -o test_vitals \
+ *      test_vitals_count_presence.c && ./test_vitals
+ *
+ * Exits 0 on all-pass, prints which assertion failed otherwise.
+ *
+ * Why a separate host test file: these are deterministic logic checks for the
+ * exact boundary behaviour the issues describe; libFuzzer adds no signal here.
+ *
+ * IMPORTANT — these three functions are copied VERBATIM from
+ * firmware/esp32-csi-node/main/edge_processing.c. They are pure (no globals,
+ * no ESP-IDF). If the firmware copy changes, update the copy here and re-run
+ * this test before the firmware change merges. The named tuning constants are
+ * pulled from the real header so the test and firmware can never disagree on
+ * thresholds.
+ *
+ * HARDWARE-GATED CAVEAT: these tests pin the *logic* (no flicker / no
+ * over-count for the synthetic traces). True count accuracy and the exact
+ * energy/separation/hysteresis thresholds that best match a real room vs
+ * labelled ground truth remain hardware- and data-gated (COM9 ESP32-S3 +
+ * labelled occupancy). This is a robustness/logic fix, not a validated

+`/homecore`, alongside the HA-compat `/api` surface. It is a zero-dependency,

+cargo run -p homecore-server          # then open http://localhost:8123/homecore/
+```

+It drives the live `/api` + `/api/websocket` (`subscribe_events`) endpoints; panels
+backed by services not in this binary (SEED HTTPS API, calibration ADR-151,

+those endpoints land (ADR-131 §7.1). Frontend tests + benchmark run under plain

+cd ui && npm run bench # bundle budget (~137 KB, ~37× smaller than HA) + render timing

+//! HOMECORE-UI backend-for-frontend (BFF) gateway — ADR-131 §11.
+//!
+//! `homecore-server` is the single origin the dashboard talks to (§2.1).
+//! This module adds the `/api/homecore/*` aggregation namespace and the
+//! `/api/cal/*` reverse-proxy to the calibration service, so the browser
+//! never makes a cross-origin call and never holds an upstream credential.
+//!
+//! Implemented now (self-contained, no new external service):
+//!   * `/api/cal/*`            — reverse-proxy → calibration API (ADR-151)   [W2]
+//!   * `GET /api/homecore/rooms` — per-room RoomState, adapted to the UI shape [W2]
+//!   * `GET /api/homecore/cogs`  — COG supervisor over the apps dir           [W4]
+//!   * `GET /api/homecore/appliance` — host metrics from /proc + port probes  [W6]
+//!
+//! Returns a typed `503 upstream_unavailable` for routes whose upstream is
+//! a SEED device / appliance daemon not present in this repo (§11.2 / §12):
+//! seeds, federation, witness, privacy, settings, automations, events
+//! history, hailo, tokens. The front-end renders these as error states
+//! (it never falls back to mock in production — §2.2).
+//!
+//! NOTE: written against the real crate APIs but NOT yet compiled in the
+//! authoring environment (no Rust toolchain); run `cargo test -p
+//! homecore-server` on a Rust host.
