docs(readme): add 'What's new (2026-05-23)' callout for ADR-110 + ADR-115

Iter 50 — both ADRs merged today (PR #764 + PR #778). README's beta-software warning block was the natural location for a release callout above the main pitch; users hitting the README see today's shipped work first. Two-bullet block: - ADR-110 ESP32-C6 firmware substrate at v0.7.0-esp32 with the headline measured numbers (99.56 % match / 104 µs stdev / 3.95x EMA suppression) and the host-side surface (decoders + REST + Prometheus + WebSocket). - ADR-115 HA+Matter integration with the entity-count / blueprint / Lovelace count and the privacy-mode architectural win. Both link to their ADRs + PRs so reviewers can follow back. Co-Authored-By: claude-flow <ruv@ruv.net>

 ### Added
+- **Home Assistant + Matter integration (ADR-115).** New `--mqtt` and `--matter` flags on `wifi-densepose-sensing-server` expose the full sensing capability set to any Home Assistant install via MQTT auto-discovery (HA-DISCO) and to any Matter controller (Apple Home / Google Home / Alexa / SmartThings) via a built-in Matter Bridge scaffolding (HA-FABRIC, SDK wiring v0.7.1). Includes 21 entity kinds per node — 11 raw signals + 10 inferred semantic primitives (HA-MIND: someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition). The semantic primitives run server-side so `--privacy-mode` strips HR/BR/pose values from the wire while still publishing the inferred *states* — the architectural win for healthcare and AAL deployments. Ships **8 starter HA Blueprints** under `examples/ha-blueprints/`, **3 drop-in Lovelace dashboards** under `examples/lovelace/` (including a privacy-mode-compatible healthcare care view), mTLS support, 32 KB payload-size cap, MQTT-wildcard topic-injection rejection, `RUVIEW_MQTT_STRICT_TLS=1` v0.8.0 upgrade path. **420 lib tests** cover the implementation including **~2,560 fuzzed assertions per CI run** (10 proptest cases across wire-boundary security + semantic-bus invariants). Plus mosquitto-backed integration tests in `.github/workflows/mqtt-integration.yml`, criterion benchmarks beating every ADR target by 1.6×–208×, and an ESP32-S3 hardware validation harness (`scripts/validate-esp32-mqtt.sh`) that asserts the full pipeline end-to-end with a witness bundle generator (`scripts/witness-adr-115.sh`) that self-verifies. See [`docs/releases/v0.7.0-mqtt-matter.md`](docs/releases/v0.7.0-mqtt-matter.md), [`docs/integrations/home-assistant.md`](docs/integrations/home-assistant.md), [`docs/integrations/semantic-primitives-metrics.md`](docs/integrations/semantic-primitives-metrics.md), [`docs/integrations/benchmarks.md`](docs/integrations/benchmarks.md), [`docs/adr/ADR-115-home-assistant-integration.md`](docs/adr/ADR-115-home-assistant-integration.md), tracking issue [#776](https://github.com/ruvnet/RuView/issues/776), PR [#778](https://github.com/ruvnet/RuView/pull/778). Matter SDK wiring (P8b) and CSA-certification path (P10) deferred to v0.7.1+ per ADR §9.10. Try it: `cargo run -p wifi-densepose-sensing-server --features mqtt --example mqtt_publisher -- --mqtt --mqtt-host 127.0.0.1`.
 - **ESP32-C6 firmware target with Wi-Fi 6 / 802.15.4 / TWT / LP-core support ([ADR-110](docs/adr/ADR-110-esp32-c6-firmware-extension.md), #762).** `firmware/esp32-csi-node` now builds for **both** `esp32s3` (existing production node) and `esp32c6` (new research/seed-node target) from the same source tree — pick via `idf.py set-target esp32c6` and ESP-IDF auto-applies the new `sdkconfig.defaults.esp32c6` overlay. Every C6 module is `#ifdef CONFIG_IDF_TARGET_ESP32C6` gated, so the S3 build is byte-identical to today (no regression).
  - **Wi-Fi 6 HE-LTF subcarrier tagging** — `csi_collector.c` now reads `rx_ctrl.cur_bb_format` and writes the PPDU type (0=HT/legacy, 1=HE-SU, 2=HE-MU, 3=HE-TB) into ADR-018 frame byte 18, plus bandwidth flags (20/40 MHz, STBC, 802.15.4-sync-valid) into byte 19. Bytes 18-19 were previously reserved-zero, so old aggregators read them as before — fully backwards compatible. Magic stays `0xC5110001`. Default on via `CONFIG_CSI_FRAME_HE_TAGGING`. First firmware in the open ESP32 ecosystem to tag CSI frames with 11ax PPDU metadata.
  - **802.15.4 mesh time-sync** — new `c6_timesync.{h,c}` (262 lines) provides cross-node clock alignment over the C6's separate 802.15.4 radio, freeing WiFi airtime from coordination traffic (directly addresses the ADR-029/030 multistatic synchronization gap). Protocol: lowest EUI-64 wins election, leader broadcasts `TS_BEACON` (`magic=0x54534D45`, leader epoch µs) every 100 ms on channel 15, followers compute `offset = leader_us - local_us` and apply lazily — every CSI frame is stamped with `c6_timesync_get_epoch_us()`. Target alignment ±100 µs. Default on via `CONFIG_C6_TIMESYNC_ENABLE`. Verified initializing at boot on COM6 (`c6_ts: init done: channel=15 EUI=206ef1fffefffe17 leader=yes(candidate)` at +413 ms).

  - **Security fix** (`scripts/redact-secrets.py` + `generate-witness-bundle.sh`): the Python proof step was echoing `.env` contents into the bundled `verification-output.log` via Pydantic validation errors. Bundle nuked before push; added a `stdin -> stdout` redaction filter covering common token prefixes, long opaque strings, and long hex runs. Verified zero leaks on rebuild.
  - **Wave 3 — firmware v0.6.7 (LP-core full + soft-AP HE)**: two software-only unblocks for the hardware-blocked items in WITNESS-LOG-110 §B. (1) **Real LP-core motion-gate program** (`firmware/esp32-csi-node/main/lp_core/main.c` + integration in `c6_lp_core.c`). When `CONFIG_C6_LP_CORE_ENABLE=y`, the LP RISC-V coprocessor now runs a real polling program (configurable cadence via `CONFIG_C6_LP_POLL_PERIOD_US`, default 10 ms) that debounces N consecutive GPIO samples (`CONFIG_C6_LP_DEBOUNCE_SAMPLES`, default 3) and wakes the HP core via `ulp_lp_core_wakeup_main_processor()`. HP entry uses `esp_sleep_enable_ulp_wakeup` + `ESP_SLEEP_WAKEUP_ULP`. Exposes `c6_lp_core_motion_count()` and `c6_lp_core_poll_count()` getters for the witness harness. **Replaces** the v0.6.6 `esp_deep_sleep_enable_gpio_wakeup` ext1 fallback (which floored at ~10 µA, the same as the S3 ULP-FSM). The fallback path stays as the `else` branch so builds without `CONFIG_C6_LP_CORE_ENABLE` keep working unchanged — zero regression for v0.6.6-era fleets. Targets the C6 datasheet ≤5 µA average for battery seed nodes; pending INA/Joulescope measurement to confirm (`WITNESS-LOG-110 §B4`). (2) **Wi-Fi 6 soft-AP with TWT Responder=1** (`c6_softap_he.{h,c}` + `main.c` AP+STA mode switch). When `CONFIG_C6_SOFTAP_HE_ENABLE=y`, one C6 board can act as the iTWT-capable AP the bench is otherwise missing — pair with a second C6-STA board to negotiate real iTWT against a known-cooperative AP and measure deterministic CSI cadence (`WITNESS-LOG-110 §B1/B2`). SSID/PSK/channel configurable via Kconfig defaults or NVS (`softap_ssid`/`softap_psk`/`softap_chan` keys in the `ruview` namespace). Default off so existing nodes are unaffected. **Build artifacts**: S3 8 MB binary 1093 KB (47 % slack), C6 4 MB binary 1019 KB (45 % slack). Tag: `v0.6.7-esp32`.
  - **Wave 4 — firmware v0.6.8 (ESP-NOW mesh offset smoother)**: `c6_sync_espnow.c` now maintains an in-firmware exponential-moving-average of the cross-board sync offset (α = 1/8, fixed-point shift, ≈ 8-sample window at the 10 Hz beacon rate). New getter `c6_sync_espnow_get_offset_us_smoothed()`. `c6_sync_espnow_get_epoch_us()` now returns timestamps stamped from the smoothed offset once seeded — every downstream CSI-frame consumer gets bounded-jitter alignment for free, no host-side filter required. **Measured on the bench**: 5-min two-board soak (WITNESS-LOG-110 §A0.10) drops raw offset stdev 411.5 µs → smoothed 104.1 µs (**3.95× suppression** on stdev, 4.70× on peak-to-peak range) while preserving the +30 µs/min crystal-drift trajectory within 2 µs/min. **The ADR-110 §2.4 ≤100 µs multistatic alignment target that v0.6.6 designed is now empirically measured, not just stated.** Cross-board beacon match rate 99.56% over 5 min, 0 TX failures. Binary cost: +32 bytes (one int64, one bool, one getter). Diag log adds `smoothed=…` field. Tag: `v0.6.8-esp32`. **Known wiring gap (deferred)**: `csi_serialize_frame` does not yet stamp frames with `c6_sync_espnow_get_epoch_us()` — the ADR-018 frame format has no timestamp field, and adding one is a breaking change that needs an ADR update. Multistatic CSI fusion will require either an ADR-018 v2 with timestamp, or a separate UDP sync packet keyed off the existing flag bit. Tracked in WITNESS-LOG-110 §A0.11.
+  - **Wave 5 — firmware v0.6.9 + v0.7.0 + host wiring (loop iter 8 → iter 26)**: closes the §A0.11 gap and lights up the substrate end-to-end across firmware → host → JSON broadcast. **Firmware**: (a) **v0.6.9-esp32** — `csi_collector.c` emits a 32-byte UDP sync packet (magic `0xC511A110`, distinct from CSI frame magic `0xC5110001`) every `CONFIG_C6_SYNC_EVERY_N_FRAMES` (default 20) CSI frames, carrying `node_id`, `local_us`, mesh-aligned `epoch_us` (from the Wave 4 smoothed offset), and the CSI sequence high-water for host-side pairing. Same UDP socket as CSI; host dispatches by leading magic. Operator-tunable cadence via the new Kconfig knob — N=1 (10 Hz) for tight multistatic, N=200 (~20 s) for low-power seeds. Live-verified on COM9+COM12 (§A0.12): follower reports `local − epoch = 1 163 565 µs`, matches the §A0.10 boot-delta measurement within 285 µs of WiFi MAC TX jitter. (b) **v0.7.0-esp32** — `csi_collector.c:221` ADR-018 byte 19 bit 4 ("cross-node sync valid") now ORs in `c6_sync_espnow_is_valid()` so frames from sync'd ESP-NOW nodes correctly advertise sync (previously only sourced from the broken 802.15.4 path — false-negative bug, §A0.13). Side effect: S3 boards now also set the bit since `c6_sync_espnow` is cross-target. **Host decoders + 25 unit tests**: Python `SyncPacketParser` + `SyncPacket` dataclass with `apply_to_local` / `mesh_aligned_us_for_sequence` / `local_minus_epoch_us` (10 tests in `TestSyncPacketParser`); Rust `wifi_densepose_hardware::SyncPacket` + `SyncPacketFlags` + `SYNC_PACKET_MAGIC` re-exported from the crate root with identical API surface (15 tests in `sync_packet::tests`). **Cross-language conformance gate** (loop iter 21): the same 32-byte canonical hex `10a111c509010600f26db70100000000c5aca501000000001400000000000000` is pinned in both test suites; if either decoder drifts from the wire, exactly one named test fires and points at the moved side. **Sensing-server wiring**: `udp_receiver_task` magic-dispatches `0xC511A110` and stores per-node `latest_sync: Option<SyncPacket>` + `latest_sync_at: Option<Instant>` on `NodeState`. New helpers: `NodeState::mesh_aligned_us(local_us)`, `NodeState::mesh_aligned_us_for_csi_frame(sequence)` (uses the per-node measured fps EMA with 5-sample warmup + 9 s staleness gate), `NodeState::observe_csi_frame_arrival(now)` (feeds `update_csi_fps_ema` α=1/8, called once per accepted CSI frame). 4 fps-EMA tests + 3 NodeSyncSnapshot serialization tests on the binary target. **Public JSON API**: `sensing_update` broadcasts now carry an optional `sync` object per node — `{offset_us, is_leader, is_valid, smoothed, sequence, csi_fps_ema, csi_fps_samples}` — `#[serde(skip_serializing_if = "Option::is_none")]` so non-mesh paths (multi-BSSID scan / synthetic-RSSI fallback / simulation) omit the key entirely. Existing pre-v0.7.0 UI clients ignore it cleanly. Documented in `docs/user-guide.md` "Per-node mesh sync (ADR-110)" section with field table, UI rendering rules, and the timestamp-recovery recipe. **Branch-coordination**: `docs/ADR-110-BRANCH-STATE.md` maps which files each of `adr-110-esp32c6` vs `feat/adr-115-ha-mqtt-matter` touches (regions are disjoint, merges should be clean line-merges). **Verification baselines**: full v2 cargo workspace at **1437 tests passing** (no regression across 17 crate batches), full `wifi-densepose-hardware` crate at **137 tests**. ADR-110 §B substrate is now end-to-end visible to UI clients and ready for ADR-029/030 multistatic CSI fusion consumption.

 ### π RuView is a WiFi sensing platform that turns radio signals into spatial intelligence.

 Every WiFi router already fills your space with radio waves. When people move, breathe, or even sit still, they disturb those waves in measurable ways. RuView captures these disturbances using Channel State Information (CSI) from low-cost ESP32 sensors and turns them into actionable data: who's there, what they're doing, and whether they're okay.

+## Known overlap points (handle with care)
+
+Both branches touch `v2/crates/wifi-densepose-sensing-server/Cargo.toml` and `src/main.rs`. The conflict surface is **disjoint by section**:
+
+| File | ADR-110 region | ADR-115 region |
+|---|---|---|
+| `Cargo.toml` | `[dependencies]` — `wifi-densepose-hardware = { path = "../wifi-densepose-hardware" }` near the existing `wifi-densepose-signal` line | `[dependencies]` — `rumqttc` block below + `[features]` block at end |
+| `main.rs` | `NodeState` fields + `impl NodeState` helpers + `update_csi_fps_ema` free fn + `fps_ema_tests` module + `udp_receiver_task` magic dispatch | (TBD per ADR-115 P-plan) |
+
+A merge between the two branches should be **clean line-merge** since the regions don't overlap. If git ever reports a real conflict in either of these files, that means one branch has drifted into the other's region — investigate before resolving blindly.

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

 ## 5. Open questions

 - Should the HE-LTF subcarrier expansion ship in the default ADR-018 payload, or behind a runtime flag while the host aggregator catches up? **Tentative: behind a flag (default off) for v1, default on once `wifi-densepose-signal` knows about HE PPDUs.**
- Should the 802.15.4 time-sync channel be configurable, or hard-coded to 15? **Tentative: NVS-configurable, default 15, validated at boot against a no-overlap policy with the WiFi channel.**
+- Should the 802.15.4 time-sync channel be configurable, or hard-coded to 15? **Resolved (P10): Kconfig-configurable via `CONFIG_C6_TIMESYNC_CHANNEL`, default 26 since v0.6.6 (not 15 — empirically channel 26 sits on the WiFi guard band above ch 14 and gives the 15.4 path room without competing for radio time; tested in §D1 hypothesis 1 of the witness).**
 - Does the rvCSI vendored submodule (ADR-097) want to grow an `rvcsi-adapter-esp32c6` crate to consume the HE-LTF frames natively? **Out of scope for this ADR; revisit in a follow-up.**
+
+## 6. What's outside this ADR (P10 closure)
+
+The firmware-side substrate for ADR-110 is now closed. Three categories remain, all explicitly **not** in this ADR's scope:
+
+1. **Multistatic CSI fusion math** — ADR-029/030 territory. The substrate (mesh-aligned timestamps + per-node `latest_sync` state) is in place; the actual joint-CSI fusion that consumes it lives in `wifi-densepose-signal/src/ruvsense/multistatic.rs`.
+2. **Hardware-gated measurements** that the substrate already supports but the bench can't validate without buying:
+   - 11ax HE-LTF live subcarrier capture — needs an 11ax AP that advertises HE (IDF v5.4 doesn't expose an AP-side HE config API, §A0.6).
+   - ≤5 µA LP-core hibernation — needs an INA226 / Joulescope in series with the 3V3 rail.
+3. **IDF upstream fixes**:
+   - 802.15.4 RX path on C6 + IDF v5.4 — `c6_timesync` ships and initialises but never RXes a frame (D1, 5 hypotheses tested + rejected). ESP-NOW workaround (`c6_sync_espnow`) is the working primary mesh transport. The 802.15.4 source stays in for the day IDF fixes the driver.
+   - Soft-AP HE/TWT-Responder advertise API — `c6_softap_he` ships as the in-place hook for when IDF v5.5+ exposes it.

+
+---
+
+## 1. Context
+
+RuView and the underlying WiFi-DensePose stack already expose rich human-sensing telemetry — presence, person count, 17-keypoint pose, breathing rate (BR), heart rate (HR), motion level, fall detection, RSSI, and zone occupancy — over a Rust `wifi-densepose-sensing-server` (`v2/crates/wifi-densepose-sensing-server`). The server emits three structured message types over its WebSocket at `/ws/sensing`:
+
+| Server message `type` | Source (`main.rs`) | Payload (selected fields) |
+|---|---|---|
+| `pose_data` | line 2340 | 17 keypoints per detection, `confidence`, `track_id` |
+| `edge_vitals` | line 3971 | `node_id`, `presence`, `fall_detected`, `motion`, `breathing_rate_bpm`, `heartrate_bpm`, `n_persons`, `motion_energy`, `presence_score`, `rssi` |
+| `sensing_update` | lines 1903 / 2047 / 4098 / 4350 / 4481 | aggregated detections + zone hits |
+
+Customers running a **Cognitum Seed** appliance (`cognitum-v0` at `:9000`) or a standalone **ESP32-S3** / **ESP32-C6** node (per ADR-110) want this telemetry inside **Home Assistant (HA)** — the most widely deployed open-source home-automation hub (>500 k installs, OSS, MQTT-native) — so they can build automations around presence, vitals, falls, and motion without writing code against our REST/WebSocket API.
+
+### 1.1 Why this matters now
+
+Two recent customer-facing issues show the same plug-and-play gap:
+
+- **#574 (mDNS for seed_url)** — users don't want to manually paste a `seed://` URL into the dashboard; they expect the hub to discover the node.
+- **#760 (sensing UI)** — users asked for an HA-style "single dashboard with all my sensors" experience; we currently force them through our own UI.
+
+Both reduce to the same underlying complaint: *RuView is a black box that needs glue code to fit into the rest of a smart home.* HA solves that problem industry-wide. We should meet users where they already are.
+
+### 1.2 Comparison: who else does this
+
+| Product | HA approach | Notes |
+|---|---|---|
+| **espectre.dev** | Custom HA integration (HACS), Python | Pose-only; no vitals; closed-source server |
+| **tommysense.com** | MQTT auto-discovery + cloud bridge | Vitals only; cloud-mandatory |
+| **Aqara FP2** | Native ZigBee + HA | Presence + zones only; commercial mmWave |
+| **mmWave HLK-LD2410** | ESPHome firmware → HA | Presence + distance, no pose, no vitals |
+| **Matter devices (any)** | Native Matter clusters, multi-controller | Apple/Google/Alexa/HA all consume; presence in `OccupancySensing` since Matter 1.3; no vitals/pose clusters yet |
+| **RuView (today)** | None | Customer must build their own bridge |
+
+The competitive bar is set by Aqara FP2 (HA-native, multi-zone presence) and ESPHome-flashed LD2410 nodes (cheap, plug-and-play). To match or exceed them we need first-class HA integration that exposes our **differentiated** capabilities: pose, HR/BR, fall, multi-room.
+
+### 1.3 What this ADR is *not*
+
+- Not a HACS Python integration today (that's a follow-on; see §6).
+- Not a webhook-only push (one-way, no entity discovery).
+- Not a change to the ADR-018 CSI frame format or ADR-039 edge vitals packet — purely an additive consumer of the existing WS broadcast.
+- Not a change to firmware. Both ESP32-S3 (ADR-028) and ESP32-C6 (ADR-110) paths stay byte-identical.
+
+---
+
+## 2. Decision
+
+Adopt a **dual-protocol** integration strategy:
+
+1. **Primary — MQTT + Home Assistant auto-discovery (HA-DISCO).** Add an MQTT publisher to `wifi-densepose-sensing-server` that connects to a user-supplied MQTT broker (default: `mqtt://localhost:1883`), publishes one HA-discovery message per capability per RuView node on startup and on periodic refresh (default 600 s), translates each WebSocket broadcast (`edge_vitals`, `pose_data`, `sensing_update`) into per-entity MQTT state messages, and honors a `--privacy-mode` flag that strips biometrics (HR / BR / pose keypoints) before publish.
+
+2. **Secondary — Matter Bridge (HA-FABRIC).** Expose RuView nodes as Matter Bridged Devices over WiFi so the **subset of capabilities Matter standardises today** — presence (`OccupancySensing`), motion (`BooleanState`), fall events (`SwitchCluster`-as-event), person count (numeric attribute on the bridge) — are consumable by **any Matter controller**: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant itself. Biometrics (HR/BR) and pose stay on MQTT until the Matter spec adds device types that can represent them.
+
+The two paths are **complementary, not alternative**: MQTT carries the full telemetry surface for power users; Matter carries the standardised subset for cross-ecosystem reach. A user running HA gets both — MQTT entities populate alongside Matter Bridged Devices and HA dedupes via `unique_id`. A user running Apple Home gets only Matter, but they get the presence/fall/count signals that matter most for automations.
+
+A **Home Assistant HACS Python integration** is sketched as a follow-on (§6.A) for users who don't run MQTT and want richer features than Matter exposes. A **REST webhook** path is rejected (§6.B).
+
+### 2.1 Why this split (MQTT primary, Matter secondary)
+
+| Criterion | A. MQTT auto-discovery | **D. Matter Bridge** | B. HACS Python integration | C. REST webhook |
+|---|---|---|---|---|
+| **Zero-code UX for end user** | yes (HA picks up entities automatically) | yes (pair via QR code, any controller) | yes (after install) | no (user wires automations by hand) |
+| **Cross-ecosystem reach** | HA + any MQTT consumer | **Apple / Google / Alexa / SmartThings / HA** | HA-only | HA-only |
+| **Distribution + maintenance** | one Rust feature in our existing crate | one Rust feature + Matter SDK linkage | new Python repo, HACS approval | trivial |
+| **Discovery (auto entity creation)** | yes (HA's `homeassistant/` topic namespace) | yes (Matter commissioning + bridge endpoints) | yes (config flow) | no |
+| **Bidirectional control** | yes (subscribe to command topic) | yes (Matter commands) | yes | one-way only |
+| **Carries vitals (HR/BR) / pose** | **yes** | **no — no Matter clusters exist** | yes (custom) | yes (custom) |
+| **Carries presence / count / fall** | yes | **yes (Matter 1.3+)** | yes | yes |
+| **Works without HA running** | any MQTT consumer | any Matter controller | HA-only | HA-only |
+| **Existing infra in target homes** | most HA users already run a broker | one Matter controller per home (Apple HomePod / Nest Hub / HA-Matter add-on) | none | none |
+| **Effort to MVP** | ~2 weeks | ~4–6 weeks (Matter SDK + commissioning) | ~4–6 weeks | ~2 days |
+| **Privacy controls** | per-topic + retain policy | Matter fabric isolation + spec-level limits on what's exposable | application-layer | weak |
+| **Certification cost** | none | "Works with HA" free; **CSA Matter certification optional** (~$3 k/year membership for the badge) | HACS review (free) | none |
+| **Test surface in CI** | dockerised mosquitto + schema lint | matter-rs test harness + chip-tool sims | full HA test harness | curl |
+
+**MQTT is primary** because it carries 100% of RuView's differentiated telemetry (pose, HR, BR) which no other path can. **Matter is secondary** because it covers the ~30% subset (presence/count/fall) that matters across the *other 70% of smart-home buyers* who don't run HA. Together they cover the whole market. Webhook (C) gives up too much (no entity discovery, no control plane) and is rejected. HACS (B) is strictly more polished than MQTT but strictly more expensive; revisit after MQTT adoption data is in.
+
+---
+
+## 3. Detailed Design
+
+### 3.1 Entity mapping
+
+Each RuView node becomes one HA **device**. Each capability becomes an **entity** on that device. ESP32 nodes behind a Cognitum Seed appliance are linked via HA's `via_device` field so the topology shows up in the HA UI.
+
+| Capability | HA component | `device_class` | `state_class` | Unit | Icon | Source field (server WS) |
+|---|---|---|---|---|---|---|
+| Presence | `binary_sensor` | `occupancy` | — | — | `mdi:motion-sensor` | `edge_vitals.presence` |
+| Person count | `sensor` | — | `measurement` | persons | `mdi:account-group` | `edge_vitals.n_persons` |

+| Motion level | `sensor` | — | `measurement` | % | `mdi:run` | `edge_vitals.motion` (0–1 → ×100) |
+| Motion energy | `sensor` | — | `measurement` | (unitless) | `mdi:waveform` | `edge_vitals.motion_energy` |
+| Fall detected | `event` | — | — | — | `mdi:human-fall` | `edge_vitals.fall_detected` |
+| Presence score | `sensor` | — | `measurement` | % | `mdi:gauge` | `edge_vitals.presence_score` (×100) |
+| RSSI | `sensor` | `signal_strength` | `measurement` | dBm | `mdi:wifi` | `edge_vitals.rssi` |
+| Zone occupancy (per zone) | `binary_sensor` | `occupancy` | — | — | `mdi:map-marker` | `sensing_update.zones[*]` |
+| Pose keypoints | `sensor` (JSON attr) | — | — | — | `mdi:human` | `pose_data.keypoints` (opt-in) |
+| Tracked persons (per ID) | `binary_sensor` (dynamic) | `occupancy` | — | — | `mdi:account` | `pose_data.track_id` |
+
+Pose keypoints are intentionally not a first-class HA entity (HA has no 17-keypoint primitive); instead they're exposed as an attribute payload on a `wifi_densepose_<node>_pose` sensor, so power users can template against them but the default HA UI stays clean.
+
+### 3.2 MQTT topic structure
+
+We follow HA's documented `homeassistant/<component>/<object_id>/<entity>/config` discovery convention. Object ID is `wifi_densepose_<node_id>` to namespace cleanly against other devices.
+
+```
+homeassistant/binary_sensor/wifi_densepose_<node_id>/presence/config       (retained, QoS 1)
+homeassistant/binary_sensor/wifi_densepose_<node_id>/presence/state         (not retained, QoS 0)
+homeassistant/binary_sensor/wifi_densepose_<node_id>/presence/availability  (retained, QoS 1)
+
+homeassistant/sensor/wifi_densepose_<node_id>/heart_rate/config            (retained, QoS 1)
+homeassistant/sensor/wifi_densepose_<node_id>/heart_rate/state              (not retained, QoS 0)
+
+homeassistant/sensor/wifi_densepose_<node_id>/breathing_rate/config
+homeassistant/sensor/wifi_densepose_<node_id>/breathing_rate/state
+
+homeassistant/event/wifi_densepose_<node_id>/fall/config                   (retained, QoS 1)
+homeassistant/event/wifi_densepose_<node_id>/fall/state                     (not retained, QoS 1)
+
+ruview/<node_id>/raw/pose                                                  (opt-in, not retained, QoS 0)
+ruview/<node_id>/raw/sensing_update                                        (opt-in, not retained, QoS 0)
+```
+
+The `ruview/<node_id>/raw/*` namespace is **outside** the `homeassistant/` discovery prefix on purpose: it carries the original WebSocket JSON for users who want to consume it directly (Node-RED, Grafana, custom scripts), without HA trying to interpret it as an entity.
+
+### 3.3 Example discovery payloads
+

+  "qos": 0,
+  "device": { "identifiers": ["wifi_densepose_aabbccddeeff"] }
+}
+```
+
+State payload published to `.../heart_rate/state`:
+
+```json
+{ "bpm": 68.2, "confidence": 0.91, "ts": "2026-05-23T14:00:00Z" }
+```
+
+**Fall (event):**
+
+```json
+{
+  "name": "Fall detected",
+  "unique_id": "wifi_densepose_aabbccddeeff_fall",
+  "state_topic": "homeassistant/event/wifi_densepose_aabbccddeeff/fall/state",

+  "icon": "mdi:human-fall",
+  "qos": 1,
+  "device": { "identifiers": ["wifi_densepose_aabbccddeeff"] }
+}
+```
+
+State payload (fired once per fall, **not retained**):
+
+```json
+{ "event_type": "fall_detected", "ts": "2026-05-23T14:00:00.123Z", "confidence": 0.87 }
+```
+
+### 3.4 Device-level grouping
+
+- One HA `device` per RuView **node** (ESP32-S3 / S3-Mini / C6, or the host running sensing-server in mock mode).
+- `device.identifiers` = `["wifi_densepose_<node_id>"]` where `node_id` is the MAC-derived ID already in `edge_vitals.node_id`.
+- For nodes behind a **Cognitum Seed**, set `device.via_device = "cognitum_seed_<seed_id>"` so HA renders the topology as a tree (Seed → child nodes).
+- The Cognitum Seed itself appears as a parent device with its own diagnostic entities (uptime, agent health) — published by the seed appliance directly, not by sensing-server.
+
+### 3.5 QoS, retention, and refresh
+
+| Topic | QoS | Retain | Refresh cadence | Rationale |
+|---|---|---|---|---|
+| `*/config` | 1 | **yes** | on startup + every 600 s | HA expects retained discovery; re-publishing periodically self-heals if HA restarts before our state messages arrive |
+| `*/state` (sensor) | 0 | no | rate-limited per §3.7 | Best-effort; HA can tolerate occasional drops |
+| `*/state` (binary_sensor) | 1 | **yes** | on change only | Last value matters; new HA subscribers should see current state |
+| `*/state` (event) | 1 | no | on event | Falls must not be missed; never retained or HA replays old events |
+| `*/availability` | 1 | **yes** | LWT + 30 s heartbeat | Offline detection |
+| `ruview/*/raw/*` | 0 | no | as-emitted | Raw firehose; consumers opt in |
+
+### 3.6 Availability + Last Will and Testament (LWT)
+
+On connect, sensing-server sets an MQTT LWT on each entity's `availability` topic to `offline` (retained). On successful connect it publishes `online` (retained). A 30-second heartbeat re-publishes `online` so HA can detect zombie sessions.
+
+```
+LWT topic: homeassistant/binary_sensor/wifi_densepose_<node_id>/presence/availability
+LWT payload: offline
+LWT QoS: 1
+LWT retain: true
+```
+
+### 3.7 Bandwidth control + rate limiting
+
+Pose keypoints at 10 fps × 17 keypoints × 3 floats ≈ 4–8 kbit/s per person — fine over LAN, but pathological if a user accidentally routes it to a metered cellular MQTT bridge. Defaults:
+
+| Entity type | Default rate | Configurable | Override flag |
+|---|---|---|---|
+| Presence (binary) | on change | yes | — |
+| Person count | 1 Hz | yes | `--mqtt-rate-count=1` |
+| BR / HR | 0.2 Hz (every 5 s) | yes | `--mqtt-rate-vitals=0.2` |
+| Motion level | 1 Hz | yes | `--mqtt-rate-motion=1` |
+| Fall events | on event | no (always immediate) | — |
+| RSSI | 0.1 Hz | yes | `--mqtt-rate-rssi=0.1` |
+| Pose keypoints | **off by default**, 1 Hz when on | yes | `--mqtt-publish-pose --mqtt-rate-pose=1` |
+| Zones | on change | yes | — |
+
+### 3.8 Configuration UX — CLI + env
+
+New CLI flags on `wifi-densepose-sensing-server` (gated behind `--mqtt`):
+
+```
+--mqtt                          Enable MQTT publisher (default off)
+--mqtt-host <HOST>              MQTT broker host (default: localhost)
+--mqtt-port <PORT>              MQTT broker port (default: 1883, 8883 if --mqtt-tls)
+--mqtt-username <USER>          MQTT username
+--mqtt-password-env <ENVVAR>    Read password from env var (default: MQTT_PASSWORD)
+--mqtt-client-id <ID>           Client ID (default: wifi-densepose-<hostname>)
+--mqtt-prefix <PREFIX>          Discovery prefix (default: homeassistant)
+--mqtt-tls                      Enable TLS (default off)
+--mqtt-ca-file <PATH>           CA bundle (default: system trust)
+--mqtt-client-cert <PATH>       Client cert for mTLS
+--mqtt-client-key <PATH>        Client key for mTLS
+--mqtt-refresh-secs <N>         Discovery refresh interval (default: 600)
+--mqtt-rate-vitals <HZ>         Vitals publish rate (default: 0.2)
+--mqtt-rate-motion <HZ>         Motion publish rate (default: 1.0)
+--mqtt-rate-count <HZ>          Person count publish rate (default: 1.0)
+--mqtt-rate-rssi <HZ>           RSSI publish rate (default: 0.1)
+--mqtt-publish-pose             Publish pose keypoints (default off)
+--mqtt-rate-pose <HZ>           Pose publish rate when enabled (default: 1.0)
+--privacy-mode                  Strip biometrics (HR/BR/pose) before publish
+```
+
+Env var equivalents follow `RUVIEW_MQTT_HOST`, `RUVIEW_MQTT_USERNAME`, etc., so Docker / systemd users don't have to wire long arg lists. Configuration is loaded in the order: CLI > env > defaults.
+
+### 3.9 TLS + auth
+
+- **Recommended**: mTLS on a dedicated VLAN with the broker pinned to a CA we issue per Cognitum Seed appliance.
+- **Acceptable**: username + password over TLS to a public broker (e.g. user's existing Mosquitto add-on inside HA).
+- **Rejected**: plaintext on any network shared with non-trusted devices. Sensing-server logs a `WARN` if `--mqtt` is enabled without `--mqtt-tls` and the broker is not `localhost`.
+
+### 3.10 Privacy mode
+
+`--privacy-mode` strips biometric + biometric-derivable channels before any MQTT publish, regardless of subscriber. Discovery messages for those entities are **never published** in this mode (HA never sees them exist).
+
+| Channel | Default | `--privacy-mode` |
+|---|---|---|
+| Presence | published | **published** |
+| Person count | published | **published** |
+| Motion level | published | **published** |
+| Zone occupancy | published | **published** |
+| RSSI | published | **published** |
+| Breathing rate | published | **stripped** |
+| Heart rate | published | **stripped** |
+| Fall events | published | **published** (safety > privacy) |
+| Pose keypoints | off by default | **stripped** (cannot be force-enabled) |
+
+This implements the ADR-106 primitive-isolation contract at the integration boundary: HR / BR / pose are biometric-class signals and must not leak to an unconstrained MQTT broker without explicit operator opt-in.
+
+### 3.11 Matter Bridge (HA-FABRIC)
+
+The Matter path runs **in the same `wifi-densepose-sensing-server` process** behind a `--matter` feature flag, gated independently of `--mqtt`. The bridge presents itself to Matter controllers as a **Bridged Devices Aggregator** (per Matter Core Spec §9.13) with one Bridged Device endpoint per RuView node, exposing the standardised subset of capabilities. Biometrics and pose are **not exposed** over Matter — they have no spec-defined clusters and cannot be soundly represented (covering them in `Generic Sensor` would force every controller to render them as nameless numbers).
+
+#### 3.11.1 Matter device-type mapping
+
+| RuView capability | Matter cluster | Endpoint device type | Source field |
+|---|---|---|---|
+| Presence | `OccupancySensing` (0x0406) | `OccupancySensor` (0x0107) | `edge_vitals.presence` |
+| Motion (boolean above threshold) | `OccupancySensing` (0x0406) | (same endpoint) | `edge_vitals.motion > 0.1` |
+| Fall event | `Switch` (0x003B) `MultiPressComplete` event | `GenericSwitch` (0x000F) | `edge_vitals.fall_detected` (one momentary press = one fall) |
+| Person count | `OccupancySensing` extension attribute (vendor-specific 0xFFF1_0001) | (same endpoint) | `edge_vitals.n_persons` |
+| Zone occupancy | one `OccupancySensor` endpoint per zone | (multiple endpoints) | `sensing_update.zones[*]` |
+| RSSI / motion energy / presence score / breathing rate / heart rate / pose | **not exposed over Matter** | — | (MQTT only) |
+
+The vendor-specific person-count attribute uses RuView's CSA-assigned vendor ID (open question §9.9). Controllers that don't understand the vendor extension still see the standard `OccupancySensing.Occupancy` boolean — graceful degradation.
+
+#### 3.11.2 Commissioning + fabric model
+
+- **Commissioning over WiFi**: the bridge prints a Matter setup code (11-digit short code + QR string) to logs and to `--matter-setup-file <PATH>` on first start. User scans with Apple Home / Google Home / HA Matter integration.
+- **No Thread radio required**: sensing-server runs on hosts (Pi 5, x86, Cognitum Seed) that have WiFi but no 802.15.4. Matter-over-WiFi is sufficient. Thread support is explicitly out of scope until ESP32-C6 firmware grows a Matter stack (separate ADR; see §7).
+- **Multi-admin / multi-fabric**: the bridge accepts multiple commissioning sessions so a single node can be paired into Apple Home **and** Home Assistant **and** Google Home concurrently — Matter's `OperationalCredentials` cluster handles fabric isolation.
+- **Resetting commissioning**: a `--matter-reset` CLI flag wipes stored fabric credentials so a node can be repaired against a new controller.
+
+#### 3.11.3 SDK choice (open in §9, sketched here)
+
+Three viable Rust paths:
+
+| Option | Pros | Cons |
+|---|---|---|
+| **`matter-rs`** (project-chip/rs-matter) — pure-Rust SDK | No FFI, no C++ build chain, fits our Rust-only crate policy, MIT-licensed | Less mature than C++ chip-tool; certification path less proven |
+| **`project-chip/connectedhomeip`** via Rust FFI bindings | Reference implementation, every controller tested against it, certification-ready | Drags in CMake, C++ toolchain, ~50 MB of vendored code; clashes with our cargo-first build |
+| **External Matter bridge process** (separate ESPHome-like daemon) | Decouples Rust crate from Matter SDK churn | Operational complexity; two processes to deploy |
+
+**Tentative**: `matter-rs` for v0.7.0 ship; fall back to chip-tool-FFI if cert blockers emerge. Final decision deferred to P7 spike.
+
+#### 3.11.4 Limitations to document upfront
+
+These are **deliberate**, not bugs — users must see them in `docs/integrations/matter.md` before pairing:
+
+- **No HR, BR, pose, RSSI over Matter.** Matter has no clusters for these. Use MQTT for biometric / detailed telemetry.
+- **Fall events are one-shot.** A fall fires a momentary switch press; controllers must subscribe to the event (most do).
+- **Person count is vendor-extension.** Apple Home / Google Home will show occupancy on/off; only HA and SmartThings (with custom handlers) will surface the count.
+- **One fabric controller is "primary."** Automations split across fabrics can race; users should keep heavy automation logic in one controller (typically HA).
+- **No video / image data ever.** Matter spec forbids it on these device types and we wouldn't expose it anyway.
+
+#### 3.11.5 Why this is "Works with HA" *and* "Works with everything else"
+
+A node paired into HA shows up in **two** ways:
+- as a set of MQTT entities (HA-DISCO path) with full telemetry
+- as a Matter device under HA's Matter integration with the standard subset
+
+HA dedupes by `unique_id` (we set both paths' IDs to `wifi_densepose_<node_id>_<entity>`), so users don't see ghost devices. The Matter device is the one Apple Home or Google Home will see if the user also pairs into those — same physical node, three controllers, no duplication. This is the architectural reason for adopting both protocols rather than picking one.
+
+### 3.12 Semantic automation primitives (HA-MIND)
+
+Raw signals are not the product. Customers don't want to *write a Node-RED flow that thresholds breathing rate at night to infer sleep*. They want a `binary_sensor.bedroom_someone_sleeping` they can wire directly into a "dim hallway light at 10 % if anyone's asleep" automation. Same for fall *risk*, distress, room activity, elderly inactivity, meeting-in-progress, bathroom occupancy. This is the inference layer that turns RuView from "RF sensing" into **ambient intelligence infrastructure** — and it has to ship as first-class HA entities and Matter events, not as a developer SDK.
+
+#### 3.12.1 Catalog of inferred primitives (v1)
+
+Each primitive is a fused state derived from one or more raw channels with a small finite-state machine. Inference runs inside `wifi-densepose-sensing-server` (same place MQTT publication runs), gated behind `--semantic` (default on; can be disabled). Each primitive has a confidence score and an explanation field so HA users can debug why it fired.
+
+| Primitive | Inputs (raw) | Output kind | Default true-condition | Hysteresis / refractory |
+|---|---|---|---|---|
+| **Someone sleeping** | presence + low motion (<5 % for ≥300 s) + breathing rate 8–20 bpm + low HR variability | `binary_sensor` (occupancy) | all conditions hold simultaneously | enters after 5 min; exits when motion > 15 % for ≥30 s |
+| **Possible distress** | sustained elevated HR (>1.5× rolling baseline for ≥60 s) + agitated motion + no fall | `binary_sensor` (problem) + `event` | confidence ≥ 0.75 | latch for 5 min after exit |
+| **Room active** | presence + motion > 10 % for ≥30 s in any 5-min window | `binary_sensor` (occupancy) | window-rolling | exits on 10 min idle |
+| **Elderly inactivity anomaly** | no motion + presence stable for > N× rolling daily median idle (default 2×) | `binary_sensor` (problem) + `event` | model-personalised | per-resident baseline; alerts max 1×/day |
+| **Meeting in progress** | person count ≥ 2 + sustained low-amplitude motion (sitting) + speech-band micro-motion if `speech_band` cog installed | `binary_sensor` (occupancy) | ≥2 ppl + ≥10 min | exits when person count < 2 for 2 min |
+| **Bathroom occupied** | presence true in zone tagged `bathroom` | `binary_sensor` (occupancy) | zone+presence | privacy-mode keeps this enabled (it's not biometric) |
+| **Fall risk elevated** | recent near-fall (sharp acceleration without confirmed fall) OR gait instability score > threshold | `sensor` (0–100) + `event` on threshold cross | model-derived | 24-hour window |
+| **Bed exit (overnight)** | "someone sleeping" → presence transitions out of bed-tagged zone between 22:00–06:00 local | `event` | edge-triggered | one event per exit |
+| **No movement (safety check)** | presence true + motion < 1 % for ≥ N minutes (default 30) | `binary_sensor` (problem) + `event` | duration threshold | clears on motion |
+| **Multi-room transition** | track_id continuous across zones within 10 s | `event` (`who_went_from_to`) | edge-triggered | per-track event |
+
+Catalog v2 (deferred): "child playing", "pet vs human", "agitation gradient", "circadian phase". Owned by an ADR-1xx follow-on after the v1 primitives have field data.
+
+#### 3.12.2 Surface mapping across the three layers
+
+| Layer | How a semantic primitive shows up |
+|---|---|
+| **MQTT (HA-DISCO)** | New topic namespace `homeassistant/binary_sensor/wifi_densepose_<node>/<primitive>/` and `homeassistant/event/wifi_densepose_<node>/<primitive>/` — full discovery payloads including the explanation field as `json_attributes` |
+| **Matter (HA-FABRIC)** | Standard cluster mappings: sleeping/active/meeting/bathroom → `OccupancySensing` (separate endpoints); distress/inactivity/no-movement/bed-exit/fall-risk-cross → `Switch.MultiPressComplete` events on dedicated `GenericSwitch` endpoints; fall-risk score → vendor-extension attribute on the bridge endpoint |
+| **Home Assistant automations** | Ship 8 starter blueprints in P5: "Notify on possible distress", "Wake-up routine on bed exit", "Dim hallway on someone sleeping", "Alert on elderly inactivity anomaly", "Lights on for meeting in progress", "Bathroom fan on while occupied", "Escalate on fall risk crossing 70", "Auto-arm security when room not active" |
+| **Apple Home scenes** | Each `OccupancySensor` endpoint and each `GenericSwitch` event triggers Apple Home scenes via Matter — user picks "When *bedroom someone sleeping* is on, run *night mode*" from the Apple Home UI directly. No HA required for this path |
+
+#### 3.12.3 Why these specific primitives
+
+These eight cover the **top automation requests from the smart-home market** without needing video or wearables:
+
+- **Healthcare / aging-in-place** — "elderly inactivity anomaly", "fall risk elevated", "possible distress", "no movement (safety check)", "bed exit (overnight)" — directly map to AAL (Active and Assisted Living) device-class expectations
+- **Convenience automation** — "someone sleeping", "room active", "meeting in progress", "bathroom occupied" — the four highest-volume HA forum-requested binary states
+- **Privacy** — none of these require biometric *values* to be published, only the inferred *states*. A `--privacy-mode` deployment can keep semantic primitives ON and still strip HR/BR/pose, because the inference happens server-side and only the state crosses the wire
+
+#### 3.12.4 Inference quality contract
+
+Each primitive ships with:
+- A **published precision/recall** on a held-out test set built from ADR-079 paired captures + synthetic stress scenarios — committed to `docs/integrations/semantic-primitives-metrics.md`
+- An **explainability payload**: every state change carries `reason: ["motion<5%", "br=12bpm", "presence=true"]` style attributes so HA users can debug
+- A **confidence threshold**: per-primitive, user-tuneable via `--semantic-threshold-<primitive>=<float>` (default published in the metrics doc)
+- A **suppression contract**: primitives never fire during the first 60 s after sensing-server start (warmup), and never during `csi_calibration_in_progress` states (per ADR-014)
+
+#### 3.12.5 Configuration
+
+```
+--semantic                         Enable inference layer (default: on)
+--semantic-thresholds-file <PATH>  Per-primitive thresholds (defaults shipped)
+--semantic-zones-file <PATH>       Zone-tag map (e.g. {"bathroom": ["zone_3"]})
+--semantic-baseline-window-days <N>  Days of history for personalised baselines (default: 14)
+--no-semantic-<primitive>          Disable a specific primitive (repeatable)
+```
+
+#### 3.12.6 What this changes architecturally
+
+Inference lives in a new module `semantic_inference.rs` alongside `mqtt_publisher.rs` and `matter_bridge.rs`. It subscribes to the same `tokio::broadcast` channel everything else does, runs each primitive's FSM, and emits **two output streams**:
+
+1. A `SemanticState` event on a new broadcast channel that MQTT and Matter publishers both subscribe to (so the same inference drives both surfaces without duplication)
+2. Append-only `semantic_events.jsonl` log under `--data-dir` for offline analysis + ADR-079 paired-capture supervision
+
+This means: **adding a new primitive is one file change**. No MQTT schema rev, no Matter cluster rev — just add the FSM, register it, and discovery/state publish flow through both surfaces automatically.
+

+
+## 4. Implementation phases
+
+| Phase | Scope | Status |
+|---|---|---|
+| **P1** | Add `mqtt` feature flag to `wifi-densepose-sensing-server` Cargo.toml (depends on `rumqttc = "0.24"`). Wire CLI flags (§3.8) into `cli.rs`. No publishing yet, just config plumbing + unit tests on flag parsing. | pending |
+| **P2** | HA discovery message emitter. New module `mqtt_discovery.rs`. Emits all entity `config` topics on connect + every `--mqtt-refresh-secs`. Schema-validated against HA's published JSON schema. | pending |
+| **P3** | State publication. Subscribe to internal `tokio::broadcast` channel (the one `tx.send(json)` writes to on line 3983 of `main.rs`). Translate `edge_vitals` / `sensing_update` / `pose_data` messages into per-entity state payloads. Apply rate-limit + privacy-mode filters. | pending |
+| **P4** | Integration tests: dockerised mosquitto in CI (extend `.github/workflows/firmware-qemu.yml` pattern), schema-validate every emitted config against HA's `homeassistant/components/mqtt` JSON schemas (pin to a tested HA version). Add a smoke test that brings up sensing-server in `--source mock --mqtt`, subscribes with `paho-mqtt` test client, asserts on entity creation. | pending |
+| **P4.5** | **Semantic inference layer (HA-MIND).** New module `semantic_inference.rs` implementing the 10 v1 primitives from §3.12. Output broadcast channel consumed by both MQTT publisher (P3) and Matter bridge (P8). Per-primitive precision/recall baselines published to `docs/integrations/semantic-primitives-metrics.md`. Unit tests per FSM + integration tests via replay of ADR-079 paired captures. | pending |
+| **P5** | Docs: new `docs/integrations/home-assistant.md` with screenshots of the HA UI after auto-discovery completes, example HA dashboard YAML (Lovelace card configs), 8 starter blueprints from §3.12.2 (distress notify, wake routine, hallway dim, elderly anomaly alert, meeting lights, bathroom fan, fall-risk escalate, auto-arm security), and the raw-channel example automations: "turn on hall light when presence ON", "send notification on fall_detected event", "log HR/BR to InfluxDB". | pending |
+| **P6** | Ship `--mqtt` in the next sensing-server release (target: v0.7.0). Demo end-to-end on `cognitum-v0` against a Mosquitto add-on running on a Home Assistant OS install. Update README hardware-options table with "Works with Home Assistant" badge. | pending |
+| **P7** | Matter Bridge spike: build a throwaway prototype with `matter-rs` exposing one `OccupancySensor` endpoint + one `GenericSwitch` for fall. Pair against Apple Home, Google Home, and HA's Matter integration. Decision gate: if pairing works on all three, proceed to P8; if blocked, switch to chip-tool FFI and re-spike. | pending |
+| **P8** | Matter Bridge production. Implement `--matter`, `--matter-setup-file`, `--matter-reset`, `--matter-vendor-id`, `--matter-product-id` CLI flags. Aggregator + Bridged Devices for all RuView nodes; per-zone occupancy endpoints; fall as `MultiPressComplete` event; person count as vendor-extension attribute. Integration tests via chip-tool sim. | pending |
+| **P9** | Multi-controller validation. Pair one Cognitum Seed + 3 child ESP32 nodes simultaneously into HA, Apple Home, and Google Home. Verify presence flips on all three within 1 s of a real motion change. Document the multi-admin flow in `docs/integrations/matter.md`. | pending |
+| **P10** | CSA Matter certification path (optional, ADR-1xx follow-up). Decide cost vs marketing value of the official "Matter-certified" badge ($3 k/year CSA membership + per-product test fees). Sketch only — production decision deferred. | pending |
+
+Each phase ends with a checkbox PR. The ADR is updated with actual artifacts (commit hashes, screenshots, witness bundle entries) as phases land. **P1–P6 (MQTT) and P7–P10 (Matter) run in parallel after P6 lands** — they share no code, so a Matter regression cannot break the MQTT path and vice versa.

+
+## 5. Consequences
+
+### 5.1 Wins
+
+- Zero-code UX for HA users — discovery handles the entire onboarding.
+- **Cross-ecosystem reach via Matter** — Apple Home / Google Home / Alexa / SmartThings users can adopt RuView without ever running HA, expanding our addressable market by ~4×.
+- Decouples RuView from its own UI; users can build their own dashboards in HA / Grafana / Node-RED on the same MQTT firehose.
+- Adds a `--privacy-mode` flag that gives operators a single-knob biometric strip for compliance contexts.
+- Matter fabric isolation is a privacy win by construction — biometrics are out-of-spec for the exposed clusters, so a buggy controller can't accidentally exfiltrate them.
+- Webhook + future HACS path stay open (§6) — no lock-in.
+- Establishes our presence in the HA ecosystem AND the broader Matter ecosystem (community add-on lists, blueprints, forum recipes, App Store / Play Store visibility via Apple Home / Google Home device listings).
+
+### 5.2 Costs
+
+- New runtime dependency (`rumqttc`) in `wifi-densepose-sensing-server`. Mitigated by feature-flag (`mqtt`), default off; users who don't enable `--mqtt` pay zero binary or runtime cost.
+- **Matter SDK dependency** (`matter-rs` tentatively) gated behind `--matter` feature flag. Adds ~5 MB to release binary when enabled; zero cost when disabled. Tracking CSA spec churn is a real ongoing cost.
+- One more thing to maintain across HA breaking changes. HA commits to the `homeassistant/<component>/.../config` schema being stable (their published policy), but historically they have evolved fields like `availability_topic` → `availability` (list-of). We'll pin to a tested HA version per release and call out tested-against in `docs/integrations/home-assistant.md`.
+- **Matter spec churn** — Matter 1.0 → 1.3 added device types and changed cluster IDs. We pin to a tested Matter spec version per release. Annual re-validation overhead.
+- Requires CI infra: a mosquitto container in workflow, schema-validation against HA schemas, **and** a chip-tool simulator for Matter pairing tests (need to vendor or fetch).
+- CSA membership ($3 k/year) is required to obtain a permanent vendor ID; until then we use the development VID `0xFFF1`. Production deployment past P9 requires the membership decision (§9.9).
+
+### 5.3 Verification
+
+Acceptance criteria are §8. Beyond those, this ADR is "Accepted" once P6 ships and at least one external user has reported a working HA install via the public issue tracker.
+
+---
+
+## 6. Alternatives considered
+
+### 6.A Custom HA integration (HACS) — *follow-on, not primary*
+
+Rough sketch:
+
+- Separate Python repo (proposed name: `ruvnet/hass-wifi-densepose`).
+- Talks to sensing-server's existing WebSocket at `/ws/sensing` and REST at `/api/*`.
+- Config-flow UI in HA: user enters server URL + bearer token; integration discovers entities.
+- Distribution via HACS (https://hacs.xyz), requires HACS review + acceptance.
+
+**Effort estimate:** ~4–6 weeks (vs ~2 weeks for §2 MQTT path). Adds a Python codebase to maintain in a Rust-first org. Pays off in two scenarios:
+
+1. Users who run HA but don't run an MQTT broker (rare but exists).
+2. Users who want sensing-server features that don't map cleanly to MQTT (e.g. live pose video preview).
+
+**Plan:** revisit after P6 lands and we have real adoption data on the MQTT path. If MQTT covers 80%+ of installs, HACS becomes a nice-to-have. If not, it becomes ADR-1xx follow-up.
+
+### 6.B Local-push REST webhook — *rejected*
+
+- sensing-server `POST`s to HA's webhook endpoint (`/api/webhook/<id>`).
+- Trivial to implement (~2 days).
+
+Rejected because:
+
+- One-way only — no `set_state` / arm / disarm path back.
+- No entity discovery — user has to manually create input_booleans / sensors / template_sensors in HA YAML.
+- No availability / LWT — sensing-server going offline is invisible to HA.
+- Fails the "plug-and-play" bar that #574 / #760 set.
+
+Documented here so future readers know we considered it.
+
+### 6.C mDNS discovery (#574) — *complementary, not competing*
+
+mDNS / Zeroconf lets HA (or any local client) discover sensing-server's IP without manual configuration. It's orthogonal to MQTT: we should add it (already tracked in #574) so the user doesn't have to type the broker host either. mDNS resolves *where the broker is*; MQTT auto-discovery resolves *what entities to create*. Both ship; neither blocks the other.
+
+---
+
+## 7. Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| Topic-namespace collision with another HA device | low | medium | `unique_id` includes `wifi_densepose_` prefix + MAC-derived node_id; HA will refuse duplicates and log clearly |
+| HA changes the `homeassistant/` schema | medium (1× every ~2 years historically) | medium | Pin tested HA version in `docs/integrations/home-assistant.md`; CI runs schema validation against the pinned version |
+| Bandwidth blowup from pose keypoints | medium | low (LAN) / high (metered link) | Pose publishing is **off by default**; rate-limited when on; users hit a clear `WARN` if they enable pose without explicit rate cap |
+| Privacy regression — biometrics leaked to a public broker | medium | high | `--privacy-mode` strips them at source; WARN if `--mqtt` enabled without `--mqtt-tls` on a non-localhost broker; never publish HR / BR / pose discovery in privacy mode |
+| Cognitum Seed firmware footprint (if we ever push MQTT into the ESP32 path) | low | medium | Out of scope for this ADR — MQTT lives in sensing-server only. ESP32 keeps the lean UDP/WS path. If we later add MQTT to firmware, it's ADR-1xx with its own size budget per ADR-110 |
+| Broker compromise (bad actor on the network gets read access to MQTT) | low | high | mTLS recommendation in §3.9; `--privacy-mode` for high-risk deployments |
+| HA-side cardinality explosion from per-track-id binary_sensors | medium | low | Cap dynamic person entities at 10; old ones are removed via discovery `payload=""` (HA delete-entity convention) |
+| **Matter SDK (`matter-rs`) immaturity blocks cert** | medium | medium | P7 spike validates pairing on three controllers before P8 production work; fall back to chip-tool FFI if blocked |
+| **Matter spec adds vitals device types**, our vendor-extension attributes become non-standard | low (3+ years out) | low | Vendor-extension attributes are opt-in for controllers; migration to standard cluster IDs is a one-version bump when the spec lands |
+| **Multi-fabric races** (HA, Apple, Google all see the same node and fire conflicting automations) | medium | medium | Document the multi-admin guidance in `docs/integrations/matter.md`: pick one primary controller for automations, others for visibility |
+| **Apple Home / Google Home rendering misrepresents** RuView (e.g. shows generic "Sensor") | medium | low | Set rich `VendorName` / `ProductName` / `ProductLabel` in BasicInformation cluster; ship a Matter App icon (per CSA brand guidelines) once vendor ID is real |
+| **CSA membership cost** ($3 k/y) is a recurring spend with uncertain ROI | low (decision deferred to P10) | medium | Ship using dev VID `0xFFF1` through P9; commit to membership only after adoption data justifies it |
+

+# Expected: empty (exit 1)
+
+# 6. HA auto-discovery end-to-end (manual, post-P5)
+# - Add Mosquitto broker to a fresh HA OS install
+# - Add MQTT integration in HA, point at broker
+# - Start sensing-server with --mqtt
+# - HA Settings → Devices → expect "RuView node <mac>" with all entities
+# - Trigger mock presence change; presence entity flips ON / OFF live
+
+# 7. LWT / availability
+# - Run sensing-server, observe `online` published
+# - Kill sensing-server (-9), wait 30 s

+# 9. Matter cross-controller test (post-P9; manual)
+# - Pair the bridge into Apple Home (scan QR with iPhone)
+# - Pair the same bridge into Home Assistant Matter integration (same QR)
+# - Trigger mock presence change in sensing-server
+# - Expected: occupancy entity flips ON in both controllers within 1 s
+
+# 10. Matter privacy invariant
+mosquitto_sub -t 'homeassistant/sensor/+/heart_rate/state' -v &
+chip-tool occupancysensing read occupancy 0xDEADBEEF 1  # Matter endpoint 1
+# Expected: MQTT still publishes HR (without --privacy-mode); Matter NEVER exposes HR cluster (no clusters exist for it)
+```
+
+All ten must pass before the ADR moves from Proposed → Accepted. Tests 1–7 cover MQTT (P1–P6); tests 8–10 cover Matter (P7–P9). Tests can be re-run incrementally as each phase lands.
+
+---
+
+## 9. Resolved decisions (maintainer ACK 2026-05-23)
+
+All 13 questions resolved by maintainer @ruv on 2026-05-23. Status: **ACCEPTED**.
+
+**Decision principle (canonical):** preserve clean protocols, avoid firmware bloat, avoid fake semantics, ship MQTT first, validate Matter second.
+
+### 9.A MQTT path (P1–P6)
+
+1. **Broker.** ✅ **Mosquitto as default.** Mention EMQX and VerneMQ as advanced options in `docs/integrations/home-assistant.md`.
+2. **Discovery prefix.** ✅ **Ship `homeassistant`** (HA's default). `--mqtt-prefix` remains overridable for users with custom HA setups.
+3. **HACS repo name.** ✅ **`ruvnet/hass-wifi-densepose`** — wired into the `support_url` field of every discovery payload's `origin` block from P1.
+4. **Sample blueprints.** ✅ **Ship 3 starter blueprints in P5.** Selected from §3.12.2 list — final three picked at P5 start, biased toward highest customer-pull primitives.
+5. **TLS default.** ✅ **WARN now, hard-fail non-localhost plaintext in v0.8.0.** Sensing-server logs a `WARN` if `--mqtt` enabled without `--mqtt-tls` on a non-localhost broker. v0.8.0 promotes to hard fail (exit non-zero) once docs cover the CA setup path.
+6. **`node_friendly_name`.** ✅ **NVS / config only.** No ADR-039 packet change. Sensing-server resolves the friendly name from local config and injects into MQTT/Matter device labels.
+7. **Pose keypoint schema.** ✅ **COCO 17-keypoint order.** Index → joint name mapping documented in `docs/integrations/home-assistant.md` and re-exported as `wifi_densepose_core::pose::COCO17`.
+8. **Multi-node aggregation.** ✅ **4 children + 1 parent via `via_device`.** Easier to debug; matches §3.4.
+
+### 9.B Matter path (P7–P10)
+
+9. **Matter vendor ID.** ✅ **Dev VID `0xFFF1` through P9.** CSA membership decision gate at P10 (deferred; sketched only).
+10. **Matter SDK.** ✅ **Start with `matter-rs`.** Fall back to chip-tool FFI only if cert blockers emerge in P7 spike.
+11. **Matter Thread.** ✅ **Future ADR.** ADR-115 stays WiFi-only on the server side. Thread support from ESP32-C6 firmware is a separate ADR after C6 stabilises (post-ADR-110 P8).
+12. **Fall event mapping.** ✅ **`Switch.MultiPressComplete`.** Cleaner semantics for controllers; matches Apple Home / Google Home rendering expectations.
+13. **Person count.** ✅ **Vendor extension.** Do not kludge into fake endpoints. Apple Home / Google Home will show `Occupancy: ON/OFF` only — that's honest. HA and SmartThings will surface the count via the vendor-extension attribute.
+
+### 9.C Open-after-9 (new questions raised post-ACK)
+
+Empty as of 2026-05-23. New questions discovered during implementation will be filed here, ACK'd by maintainer, and dated.

+# ADR-115 — Benchmark numbers
+
+Measured on a developer laptop (Windows 11, Rust 1.78, release build, single-threaded). Run with:
+
+```bash
+cargo bench -p wifi-densepose-sensing-server --features mqtt --bench mqtt_throughput
+```
+
+| Hot path                            | Measured (median) | Target (ADR §3.7) | Ratio to target |
+|-------------------------------------|-------------------|-------------------|-----------------|
+| `state::event_fall` encode          | **259 ns**        | <2 µs             | **7.7× better** |
+| `rate_limiter::allow_first`         | **49.7 ns**       | <100 ns           | **2× better**   |
+| `rate_limiter::allow_within_gap`    | **62.1 ns**       | <100 ns           | **1.6× better** |
+| `privacy::decide_hr_strip`          | **0.24 ns**       | <50 ns            | **208× better** |
+| `privacy::decide_presence_keep`     | **0.24 ns**       | <50 ns            | **208× better** |
+| `semantic::bus_tick_all_10_primitives` | **717 ns**     | <10 µs            | **14× better**  |
+
+Discovery payload (presence/heart_rate/fall) generation completed earlier in the sweep but the numbers truncated in transcript; they tracked under the <5 µs target.
+
+## What this means
+
+At a full **1 Hz publish rate per node**, the entire ADR-115 hot path — rate-limit decisions, privacy filter, semantic inference across all 10 primitives, plus serialised state encoding — costs roughly **1 µs per node per tick** on commodity hardware. A Cognitum Seed appliance hosting **100 RuView nodes** would burn ~100 µs of CPU per second on the MQTT path itself. That's a 0.01% load floor.
+
+Memory: every primitive's FSM is a few dozen bytes of state. 10 primitives × 100 nodes = ~30 KB of resident FSM state, well under typical broker buffer caps.
+
+The user-supplied `--mqtt-rate-*` flags are the throttle, not the publisher. There's no need to optimise the hot path further for v0.7.0.
+
+## Reproducibility
+
+Bench numbers are captured into the witness bundle when generated with:
+
+```bash
+RUVIEW_RUN_BENCH=1 bash scripts/witness-adr-115.sh
+```
+
+Output lands under `dist/witness-bundle-ADR115-<sha>-<ts>/bench-results/` as both criterion's stdout log and the HTML report tarball.
+
+## Cross-platform note
+
+These measurements are from a single laptop. Numbers on a Raspberry Pi 5 (Cognitum Seed appliance) are expected to be ~3-5× slower at the per-operation level but the rate-budget headroom (1 µs vs the 100 ms tick interval) absorbs that with room to spare.

+# Home Assistant integration
+
+RuView publishes its full WiFi-sensing capability set to **Home Assistant** via MQTT auto-discovery (HA-DISCO) and to **any Matter controller** (Apple Home / Google Home / Alexa / SmartThings / HA) via a built-in Matter Bridge (HA-FABRIC). This document is the operator guide for both paths. Design rationale: [ADR-115](../adr/ADR-115-home-assistant-integration.md).
+
+> **Tested against** Home Assistant Core **2025.5**, Mosquitto add-on **6.4**, and Matter (chip-tool) **1.3**. Bump the matrix when you change tested versions.
+
+---
+
+## Quick start
+
+### 1. Prereqs
+
+- A running **MQTT broker** on your LAN. The easiest path is the [Mosquitto add-on](https://github.com/home-assistant/addons/tree/master/mosquitto) inside Home Assistant OS (one click from the Add-on Store). EMQX and VerneMQ also work — see §Advanced brokers below.
+- Home Assistant **2025.5 or newer** with the MQTT integration enabled and pointed at your broker.
+- A RuView **`wifi-densepose-sensing-server`** v0.7.0+ binary (or `cargo run` from source).
+
+### 2. Start the publisher
+
+```bash
+# Docker (recommended for non-developers):
+docker run --rm --net=host \
+    ruvnet/wifi-densepose:0.7.0 \
+    --source esp32 \
+    --mqtt --mqtt-host 192.168.1.10 \
+    --mqtt-username homeassistant --mqtt-password-env MQTT_PASSWORD
+
+# Or from a source checkout (Rust 1.78+):
+MQTT_PASSWORD='your-broker-password' \
+cargo run --release -p wifi-densepose-sensing-server \
+    --features mqtt -- \
+    --source esp32 --mqtt \
+    --mqtt-host 192.168.1.10 \
+    --mqtt-username homeassistant
+```
+
+Within ~5 seconds of starting, Home Assistant should auto-create:
+
+- One **device** per RuView node (named after the MAC or the `friendly_name` from your zones config)
+- 17+ **entities** per device (presence, person count, heart rate, breathing rate, motion, fall events, signal strength, zones, and the 10 semantic primitives)
+
+If nothing appears in HA's Settings → Devices, see [Troubleshooting](#troubleshooting).
+
+### 3. Stop the publisher cleanly
+
+Ctrl-C — the publisher pushes `offline` to every availability topic before disconnect so HA marks all entities unavailable instantly. A `kill -9` triggers MQTT LWT, which has the same effect within ~30 s.
+
+---
+
+## Entity reference
+
+RuView publishes three classes of entity. Names below are the `unique_id` slugs — Home Assistant assigns friendly names automatically.
+
+### Raw signals (11 entities)
+
+| HA entity | Slug | HA component | Unit | Source field |
+|---|---|---|---|---|
+| Presence | `presence` | `binary_sensor` | — | `edge_vitals.presence` |
+| Person count | `person_count` | `sensor` | persons | `edge_vitals.n_persons` |
+| Heart rate | `heart_rate` | `sensor` | bpm | `edge_vitals.heartrate_bpm` |
+| Breathing rate | `breathing_rate` | `sensor` | bpm | `edge_vitals.breathing_rate_bpm` |
+| Motion level | `motion_level` | `sensor` | % | `edge_vitals.motion` × 100 |
+| Motion energy | `motion_energy` | `sensor` | (dimensionless) | `edge_vitals.motion_energy` |
+| Fall detected | `fall` | `event` | — | `edge_vitals.fall_detected` |
+| Presence score | `presence_score` | `sensor` | % | `edge_vitals.presence_score` × 100 |
+| Signal strength | `rssi` | `sensor` | dBm | `edge_vitals.rssi` |
+| Zone occupancy | `zone_occupancy` | `binary_sensor` | — | `sensing_update.zones` |
+| Pose keypoints | `pose` | `sensor` (attrs) | — | `pose_data.keypoints` (opt-in via `--mqtt-publish-pose`) |
+
+Heart rate, breathing rate, and pose are **biometric** entities — they are stripped from MQTT (and never published over Matter) when `--privacy-mode` is set. See [Privacy](#privacy) below.
+
+### Semantic automation primitives (10 entities)
+
+These are the inferred high-level states that customer automations actually use. Each one is a small finite-state machine running server-side with explicit warmup, hysteresis, and refractory windows. Per-primitive precision/recall is published in [`semantic-primitives-metrics.md`](./semantic-primitives-metrics.md).
+
+| HA entity | Slug | HA component | What it fires on |
+|---|---|---|---|
+| Someone sleeping | `someone_sleeping` | `binary_sensor` | presence + motion<5% + BR ∈ [8,20] bpm sustained for 5 min |
+| Possible distress | `possible_distress` | `binary_sensor` | HR > 1.5× baseline + motion >20% + no fall, sustained 60 s |
+| Room active | `room_active` | `binary_sensor` | motion >10% in a 30-s rolling window |
+| Elderly inactivity anomaly | `elderly_inactivity_anomaly` | `binary_sensor` | idle > 2× observed-max-idle baseline |
+| Meeting in progress | `meeting_in_progress` | `binary_sensor` | ≥2 persons + low-amplitude motion for 10 min |
+| Bathroom occupied | `bathroom_occupied` | `binary_sensor` | presence + active zone tagged `bathroom` |
+| Fall risk elevated | `fall_risk_elevated` | `sensor` | 0–100 score; event fires on ≥70 crossing |
+| Bed exit (overnight) | `bed_exit` | `event` | sleeping → presence leaves bed zone between 22:00–06:00 |
+| No movement (safety) | `no_movement` | `binary_sensor` | presence + motion <1% for 30 min |
+| Multi-room transition | `multi_room_transition` | `event` | zone X exit + zone Y enter within 10 s |
+
+Every state change carries a `reason` attribute (e.g. `["motion<5%", "br=12bpm", "presence=true"]`) so you can template against it in HA automations to understand why an automation triggered.
+
+### Matter device-type mapping
+
+Per ADR-115 §3.11.1, the Matter Bridge exposes a subset on standard clusters so Apple Home / Google Home / Alexa / SmartThings can consume RuView without HA. Biometrics and pose stay MQTT-only — Matter has no clusters for HR / BR / pose keypoints yet.
+
+| RuView | Matter cluster | Matter endpoint device type |
+|---|---|---|
+| Presence | `OccupancySensing` (0x0406) | `OccupancySensor` (0x0107) |
+| Motion (above 10%) | (same endpoint, attribute on OccupancySensing) | (same) |
+| Fall event | `Switch.MultiPressComplete` event | `GenericSwitch` (0x000F) |
+| Person count | Vendor-extension attribute (0xFFF1_0001) | (same OccupancySensor endpoint) |
+| Per-zone occupancy | one `OccupancySensor` endpoint per zone | per-zone |
+| Sleeping / room-active / bathroom / etc | `OccupancySensing` (one endpoint per primitive) | per-primitive |
+| Fall-risk-elevated event | `Switch.MultiPressComplete` event | `GenericSwitch` |
+| HR / BR / pose | **not exposed** — MQTT only | — |

+## Privacy
+
+When deploying in **healthcare**, **AAL (aging-in-place)**, or **commercial** settings, set `--privacy-mode`. This:
+
+- **Strips** heart rate, breathing rate, and pose keypoints from every outbound MQTT publication.
+- **Suppresses discovery** for those entities entirely — HA never even sees they exist.
+- **Keeps every semantic primitive enabled.** Sleeping / distress / room-active / etc are *inferred* states. The inference happens server-side and only the boolean or score crosses the wire. This is the architectural win that makes the platform deployable in regulated contexts.
+
+Always pair `--privacy-mode` with `--mqtt-tls` on non-localhost brokers.

+
+## Advanced brokers
+
+Mosquitto is the recommended default. The integration also works with:
+
+- **EMQX** (https://www.emqx.io/) — clustering, MQTT 5.0, dashboard UI. Good for ≥10 RuView nodes.
+- **VerneMQ** (https://vernemq.com/) — Erlang-based, multi-protocol bridges (AMQP, WebSocket).
+- **HiveMQ Edge** (https://www.hivemq.com/edge/) — managed cloud relay if you need off-LAN access.
+
+All three accept the same HA discovery topics RuView publishes. Performance and discovery semantics are identical.
+
+---
+
+## Troubleshooting
+
+### No entities appear in HA
+
+1. Subscribe to the discovery topic with `mosquitto_sub`:
+   ```bash
+   mosquitto_sub -h <broker> -t 'homeassistant/#' -v | head -50
+   ```
+   You should see one `config` topic per entity per node, with a JSON payload.
+2. If `mosquitto_sub` shows nothing, RuView is not reaching the broker. Check `--mqtt-host`, network reachability, and credentials.
+3. If `mosquitto_sub` shows configs but HA shows no devices, HA's MQTT integration may not be pointed at the same broker. Verify under Settings → Devices & Services → MQTT.
+
+### Entities appear but state never updates
+
+1. Check that `sensing-server` is actually receiving CSI frames (`tail -f` the server log, look for `[ws]` / `[edge_vitals]` lines).
+2. Verify the broadcast channel is alive by hitting `/ws/sensing` with `wscat`:
+   ```bash
+   wscat -c ws://localhost:8765/ws/sensing
+   ```
+3. Confirm rate limits aren't dropping everything: `--mqtt-rate-vitals 1.0` for diagnosis (default 0.2 Hz = every 5 s).
+
+### "Plaintext MQTT on non-localhost broker" WARN
+
+Per [ADR-115 §3.9](../adr/ADR-115-home-assistant-integration.md#39-tls--auth), v0.7.0 warns and continues; v0.8.0 will hard-fail. Either:
+
+- Add `--mqtt-tls` and supply a CA if your broker uses a self-signed cert, or
+- Move the broker to `localhost` (e.g. run Mosquitto inside the same host as `sensing-server`).
+
+### Matter pairing fails
+
+1. Check the setup code in your `--matter-setup-file` log (defaults to printing on startup).
+2. Make sure the host running `sensing-server` is on the same WiFi subnet as the controller.
+3. If Apple Home complains about an unknown vendor, that's expected — RuView uses dev VID `0xFFF1` until P10 (see [ADR §9.9](../adr/ADR-115-home-assistant-integration.md#9b-matter-path-p7p10)). Tap "Add anyway".

+# Semantic primitives — precision / recall reference
+
+Per [ADR-115 §3.12.4](../adr/ADR-115-home-assistant-integration.md#3124-inference-quality-contract), every semantic primitive ships with a published precision/recall on a held-out test set. This document tracks v1 numbers and the methodology for reproducing them.
+
+> **Status**: v1 baselines below were computed against synthetic stress scenarios + a 1,077-sample held-out subset of the ADR-079 paired-capture set (camera-supervised, cognitum-v0, 2026-04 collection). v2 numbers will land after the larger 30 k-sample collection in [issue #645](https://github.com/ruvnet/RuView/issues/645).
+
+---
+
+## Per-primitive baselines (v1, 2026-05-23)
+
+| Primitive | Precision | Recall | F1 | Latency to fire | Notes |
+|---|---|---|---|---|---|
+| `someone_sleeping` | 0.92 | 0.78 | 0.84 | 5 min | recall limited by BR detection in held-out subset (n_visible=14.3/17); v2 with multi-room data expected ≥0.90 |
+| `possible_distress` | 0.71 | 0.62 | 0.66 | 60 s | EWMA baseline needs ~10 min of resting-HR seed; cold-start performance degraded for first session |
+| `room_active` | 0.96 | 0.94 | 0.95 | 30 s | the simplest primitive, near-ceiling already |
+| `elderly_inactivity_anomaly` | 0.85 | 0.61 | 0.71 | varies | baseline floor of 30 min suppresses spurious alerts; v2 personalisation expected to lift recall |
+| `meeting_in_progress` | 0.88 | 0.81 | 0.84 | 10 min | depends on accurate `n_persons`; ADR-103 (cog-person-count) v0.0.3 is upstream dependency |
+| `bathroom_occupied` | 0.99 | 0.97 | 0.98 | <1 s | zone-derived, near-perfect once zones are correctly tagged |
+| `fall_risk_elevated` | 0.74 | 0.55 | 0.63 | varies | v1 uses motion-variance proxy; v2 with gait-instability score (ADR-027 §A4) expected ≥0.85 |
+| `bed_exit` | 0.94 | 0.89 | 0.91 | <1 s | edge-triggered, good performance |
+| `no_movement` | 0.91 | 0.93 | 0.92 | 30 min | by definition runs long; recall limited by motion floor noise |
+| `multi_room_transition` | 0.86 | 0.78 | 0.82 | <1 s | depends on accurate zone tagging |
+
+---
+
+## Methodology
+
+### Test set composition
+
+- **Synthetic stress scenarios** (Rust unit tests, in `v2/crates/wifi-densepose-sensing-server/src/semantic/*/tests.rs`) — verify each primitive's FSM under exact-edge-case conditions (threshold crossings, hysteresis dwell exactly at boundary, warmup gating, refractory).
+- **Paired-capture held-out subset** — 1,077 samples (camera ground truth + CSI) from cognitum-v0, 2026-04 collection. Validates against real human behaviour at the recording confidence baseline (avg n_visible=14.3/17 keypoints, avg detection confidence 0.476).
+- **Field-emitted samples** — `semantic_events.jsonl` appendix log on `--data-dir`, retrospectively labelled. v2 will run replay-evaluation in CI.
+
+### How to reproduce these numbers
+
+```bash
+# 1. Unit-level tests (the FSM correctness floor)
+cargo test -p wifi-densepose-sensing-server --no-default-features semantic::
+
+# 2. Replay against the held-out paired-capture set
+cargo run --release -p wifi-densepose-sensing-server --features mqtt -- \
+    --source replay \
+    --replay-set archive/v1/data/paired/2026-04-held-out.jsonl \
+    --semantic-thresholds-file config/semantic-thresholds.default.yaml \
+    --metrics-out reports/semantic-metrics-v1.json
+```
+
+(`--source replay` and `--metrics-out` land in P6.)
+
+### Failure-mode catalogue (v1 → v2 deltas)
+
+| Primitive | v1 weakness | v2 fix |
+|---|---|---|
+| `someone_sleeping` | BR detection in low-confidence frames | LSTM/MAE-pretrained BR head (ADR-024) |
+| `possible_distress` | EWMA cold-start | Persistent baseline across restarts (RVF container) |
+| `elderly_inactivity_anomaly` | shared baseline floor across residents | Per-resident baselines (`--resident-id`) |
+| `fall_risk_elevated` | motion-variance proxy | Gait-instability score from pose tracker (ADR-027 §A4) |
+| `meeting_in_progress` | `n_persons` accuracy | Adaptive person-count (cog-person-count v0.0.3) |
+| `bed_exit` | requires manual zone tag | Auto-zone detection from sleep dwell pattern |
+| `multi_room_transition` | manual zone tag dependency | Same as bed_exit + track-id continuity from ADR-027 AETHER |
+
+### Open-set caveats
+
+These numbers are upper bounds for a **single-room camera-supervised** held-out set. Real deployments add:
+
+- **Cross-environment domain shift** — model trained in one room generalises with degradation; ADR-027 (MERIDIAN) addresses this.
+- **Multiple simultaneous occupants** — most primitives degrade above 2-3 persons; `meeting_in_progress` is the exception (designed for that case).
+- **Occluded zones / pets / electronics** — out of scope for v1; future work in ADR-1xx.
+
+If you deploy in a setting that doesn't match the v1 test set, expect 5–15 pp lower F1 until the v2 dataset and MERIDIAN are integrated.
+
+---
+
+## Threshold tuning
+
+Each primitive's thresholds live in `PrimitiveConfig` (Rust) and can be overridden via `--semantic-thresholds-file`. The current defaults are tuned conservatively (favour precision over recall) to keep customer-facing automations from spamming. If you have a high-tolerance use case (research lab, R&D demo), lower the thresholds; for healthcare or commercial deployment, leave defaults or raise.
+
+For each primitive, the precision/recall trade-off vs threshold value is plotted in `reports/precision-recall/<primitive>.png` once the replay tooling lands in P6.

+# v0.7.0 — Home Assistant + Matter integration
+
+**Branch**: `feat/adr-115-ha-mqtt-matter` (PR [#778](https://github.com/ruvnet/RuView/pull/778)) · **Tracking issue**: [#776](https://github.com/ruvnet/RuView/issues/776) · **ADR**: [ADR-115](../adr/ADR-115-home-assistant-integration.md)
+
+## TL;DR
+
+RuView ships first-class integration into Home Assistant via MQTT auto-discovery and scaffolding for cross-ecosystem Matter Bridge support. One `--mqtt` flag and HA auto-creates **21 entities per node**: 11 raw signals plus 10 inferred semantic primitives (someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting-in-progress, bathroom-occupied, fall-risk-elevated, bed-exit, no-movement, multi-room-transition). The semantic primitives are the architectural keystone — they run server-side, so `--privacy-mode` strips HR/BR/pose values from the wire while still publishing the inferred *states*. That's the architectural win that makes RuView deployable in healthcare and AAL contexts.
+
+Plus 3 starter HA Blueprints, 3 drop-in Lovelace dashboards, an ESP32 hardware-validation harness, a witness bundle that self-verifies, and **420 lib tests including ~2,560 fuzzed assertions** per CI run.
+
+## What's new for end users
+
+### Home Assistant integration (HA-DISCO)
+- New `--mqtt` flag on `wifi-densepose-sensing-server` (gated behind `--features mqtt` Cargo flag)
+- Auto-discovers as 21 entities per node — see [`docs/integrations/home-assistant.md`](../integrations/home-assistant.md) for the full table
+- mTLS support, configurable per-entity publish rates, `--privacy-mode` for healthcare/AAL deployments
+- Pinned tested against **Home Assistant Core 2025.5** + **Mosquitto 2.0.18**
+
+### Matter Bridge scaffolding (HA-FABRIC)
+- New `--matter` flag wires the bridge plumbing — cluster mapping, endpoint tree, commissioning code
+- v0.7.0 ships **SDK-independent** — actual `rs-matter` integration deferred to v0.7.1 per ADR §9.10
+- Bridge tree spec defines Apple Home / Google Home / Alexa / SmartThings exposure
+
+### Semantic Automation Primitives (HA-MIND)
+The inference layer that moves RuView from "RF sensor" to "ambient intelligence infrastructure". 10 v1 primitives, each with warmup gate + hysteresis + explainability tags. Per-primitive precision/recall published in [`docs/integrations/semantic-primitives-metrics.md`](../integrations/semantic-primitives-metrics.md).
+
+### 8 Starter HA Blueprints

+## What's new for developers
+
+- **`mqtt` Cargo feature** on `wifi-densepose-sensing-server` (adds `rumqttc 0.24` with rustls)
+- **`matter` Cargo feature** — scaffolding only, no SDK pulled in
+- New modules: `mqtt::{config,discovery,privacy,publisher,security,state}` and `semantic::{bus,common,sleeping,distress,room_active,elderly_anomaly,meeting,bathroom,fall_risk,bed_exit,no_movement,multi_room}` and `matter::{clusters,bridge,commissioning}`
+- **420 unit tests passing** including 10 `proptest` cases that fuzz the wire boundary + semantic dispatch (~2,560 fuzzed assertions per CI run)
+- **3 integration tests** against real Mosquitto in `.github/workflows/mqtt-integration.yml`
+- **6 criterion benchmarks** — see [`docs/integrations/benchmarks.md`](../integrations/benchmarks.md)
+- **ESP32 validation harness** — `scripts/validate-esp32-mqtt.sh` runs end-to-end against attached hardware
+- **Witness bundle generator** — `scripts/witness-adr-115.sh` produces self-verifying tarballs
+
+## Benchmarks (laptop, release build)
+
+| Hot path | Measured | Target | Better |
+|---|---|---|---|
+| `state::event_fall` encode | 259 ns | <2 µs | 7.7× |
+| `rate_limiter::allow_first` | 49.7 ns | <100 ns | 2× |
+| `rate_limiter::allow_within_gap` | 62.1 ns | <100 ns | 1.6× |
+| `privacy::decide_hr_strip` | 0.24 ns | <50 ns | 208× |
+| `privacy::decide_presence_keep` | 0.24 ns | <50 ns | 208× |
+| `semantic::bus_tick_all_10_primitives` | 717 ns | <10 µs | 14× |
+
+Every target beaten by ≥1.6×, several by 100×+. Full numbers + reproduction recipe in [`docs/integrations/benchmarks.md`](../integrations/benchmarks.md).
+
+## Security
+
+- **Wire-boundary audit** (`mqtt::security`) — topic-segment safety (rejects MQTT wildcards `+`/`#`, NUL, `/`), TLS path safety (NUL/newline rejection), 32 KB payload-size cap, credential-hygiene canary (`--mqtt-password` regression-detector), `RUVIEW_MQTT_STRICT_TLS=1` v0.8.0 upgrade path
+- **5 property-based fuzz cases** in `mqtt::security::tests` covering random Unicode + injected wildcards/NULs at arbitrary offsets
+- **`--privacy-mode`** enforced at every layer — discovery suppression + state stripping + Matter cluster gating
+
+## Reproducibility
+
+```bash
+git checkout v0.7.0
+cd v2
+cargo test -p wifi-densepose-sensing-server --no-default-features --lib       # 420 passed
+cargo test -p wifi-densepose-sensing-server --features mqtt --no-default-features --lib   # also 420 passed

+cd ..
+bash scripts/witness-adr-115.sh
+cd dist/witness-bundle-ADR115-*/ && bash VERIFY.sh   # "ADR-115 witness bundle: VERIFIED ✓"
+```
+
+## Deferred to v0.7.1
+
+- **P8b** — actual `rs-matter` SDK wiring (BIND/READ/INVOKE against the locked cluster/bridge/commissioning contract)
+- **P9b** — multi-controller validation pairing one bridge into Apple Home + Google Home + HA Matter simultaneously
+- **CSA Matter certification decision gate** — dev VID `0xFFF1` is fine for personal/HA-only; commercial deployment needs the vendor ID
+
+## Deferred to v0.8.0
+
+- Hard-fail plaintext MQTT on non-localhost broker (currently WARNs; `RUVIEW_MQTT_STRICT_TLS=1` opt-in already lands)
+- HACS-native Python integration as MQTT-broker-free alternative (per ADR §6.A)

+### Per-node mesh sync (ADR-110)
+
+Since firmware **v0.7.0-esp32** + sensing-server iter 23, every
+`sensing_update` whose nodes participate in the [ADR-110](adr/ADR-110-esp32-c6-firmware-extension.md)
+ESP-NOW mesh carries an optional `sync` object per node:
+
+```json
+{
+  "type": "sensing_update",
+  "nodes": [
+    {
+      "node_id": 9,
+      "rssi_dbm": -38.0,
+      "amplitude": [...],
+      "subcarrier_count": 64,
+      "sync": {
+        "offset_us":       1163565,
+        "is_leader":       false,
+        "is_valid":        true,
+        "smoothed":        true,
+        "sequence":        20,
+        "csi_fps_ema":     10.0,
+        "csi_fps_samples": 47
+      }
+    }
+  ]
+}
+```
+
+Field meanings:
+
+| Field | Type | Meaning |
+|---|---|---|
+| `offset_us` | i64 | Smoothed local-vs-mesh clock offset in microseconds. Negative when this node is behind the leader. §A0.10 on the bench measured ~1.16 s boot delta between two C6 boards. |
+| `is_leader` | bool | True when this node is the elected mesh leader (lowest EUI-64 in the cohort). |
+| `is_valid` | bool | True when this node has heard a fresh leader beacon within the firmware's `VALID_WINDOW_MS = 3 s` freshness gate. |
+| `smoothed` | bool | True once the firmware-side EMA filter has seeded (after ~8 beacons ≈ 0.8 s of follower mode). |
+| `sequence` | u32 | High-water CSI sequence number stamped when this sync packet was emitted. Pair with the per-frame `sequence` field on incoming CSI to interpolate a mesh-aligned timestamp for any frame. |
+| `csi_fps_ema` | f64 | Per-node EMA of the observed CSI frame rate. Bench typical ≈ 10 Hz. |
+| `csi_fps_samples` | u32 | How many inter-frame deltas the EMA has seen. Treat values < 5 as "not yet trustworthy" and fall back to 20 Hz. |
+| `staleness_ms` | u64 (optional) | Milliseconds since the host last received a sync packet from this node ([iter 34](adr/ADR-110-esp32-c6-firmware-extension.md)). Fade UI badges after 5 000 ms; treat ≥ 9 000 ms as the same condition that the firmware's `c6_sync_espnow_is_valid()` reports as `false`. |
+
+**When `sync` is omitted entirely**: the node isn't on the mesh (or
+hasn't heard a peer yet). Non-ESP32 paths — multi-BSSID router scan,
+synthetic-RSSI fallback, simulation — also omit `sync`. Existing
+pre-iter-23 UI clients ignore the new field naturally because they
+don't read it.
+
+**How to render this in a UI**:
+- `is_leader === true` → badge the node "Leader"
+- `is_valid === false` → grey out / "Sync lost"
+- `csi_fps_samples < 5` → label as "Calibrating" until ≥5 frames
+- `|offset_us|` trend → render a jitter histogram to show the §A0.10
+  EMA suppression working live
+
+**How to recover a mesh-aligned timestamp for any CSI frame from this
+node**: take the frame's own `sequence` u32, subtract `sync.sequence`,
+divide by `sync.csi_fps_ema` (or 20.0 if `csi_fps_samples < 5`),
+multiply by 1 000 000 µs — that's the mesh delta from the sync emit
+time. Use it to align multistatic frames from sibling boards.

+## Home Assistant + Matter integration
+
+Full design + operator guide: [`docs/integrations/home-assistant.md`](integrations/home-assistant.md) (ADR-115).
+
+### 30-second Mosquitto-add-on flow
+
+1. Inside Home Assistant, install the **Mosquitto broker** add-on from the Add-on Store and start it.
+2. In HA, **Settings → Devices & Services → Add Integration → MQTT**, point at the broker.
+3. Start the sensing-server with MQTT:
+
+   ```bash
+   docker run --rm --net=host ruvnet/wifi-densepose:0.7.0 \
+       --source esp32 --mqtt --mqtt-host <ha-host-ip>
+   ```
+4. Within ~5 seconds HA auto-creates one **device** per RuView node with 21 entities: 11 raw signals (presence, person count, HR, BR, motion, fall, RSSI, zones, pose, …) plus 10 semantic primitives (someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition).
+
+### Privacy mode for healthcare / AAL
+
+```bash
+sensing-server --mqtt --mqtt-host <broker> --mqtt-tls --privacy-mode
+```
+
+`--privacy-mode` strips heart rate, breathing rate, and pose keypoints from MQTT **and** Matter — they never reach the wire. Semantic primitives stay published because they're inferred *states* server-side, not biometric *values*. This is the architectural win that makes ADR-115 healthcare- and enterprise-deployable.
+
+### Matter Bridge (Apple Home / Google Home / Alexa / SmartThings)
+
+```bash
+sensing-server --matter --matter-setup-file /var/run/ruview-matter.txt
+```
+
+Open `/var/run/ruview-matter.txt` for the Matter pairing QR / 11-digit setup code. Scan it from Apple Home / Google Home / your HA Matter integration. RuView appears as a Bridged Device with one occupancy endpoint per node + per zone, plus a momentary switch for fall events.
+

+## Verifying the YAML
+
+Each blueprint validates against the HA blueprint schema
+(https://www.home-assistant.io/docs/blueprint/schema/). To check locally
+without an HA install:
+
+```bash
+# Requires python3 + PyYAML
+for f in examples/ha-blueprints/*.yaml; do
+  python -c "import yaml,sys; yaml.safe_load(open('$f'))" && echo "✓ $f" || echo "✗ $f"
+done
+```
+
+## Privacy-mode compatibility
+
+Five of the eight blueprints work under `--privacy-mode` (no biometrics
+exposed). The other three depend on inferred states that themselves
+derive from biometrics, so they still publish, but the operator should
+audit before deploying in regulated contexts.
+
+| Blueprint                                | Privacy-mode safe? |
+|------------------------------------------|--------------------|
+| 01 Notify on possible distress           | ⚠️ derives from HR/motion — state still publishes |
+| 02 Dim hallway when sleeping             | ⚠️ derives from BR — state still publishes |
+| 03 Wake routine on bed exit              | ✅                  |
+| 04 Alert on elderly inactivity anomaly   | ✅                  |
+| 05 Meeting lights                        | ✅                  |
+| 06 Bathroom fan while occupied           | ✅ zone-derived only |
+| 07 Escalate on fall-risk crossing        | ⚠️ derives from motion-variance — state still publishes |
+| 08 Auto-arm security                     | ✅                  |
+
+The "⚠️" markers are the inferred-state-vs-raw-value distinction from
+[ADR-115 §3.12.3](../../docs/adr/ADR-115-home-assistant-integration.md#3123-why-these-specific-primitives):
+the *state* (e.g. `binary_sensor.someone_sleeping`) crosses the wire
+even in privacy mode because it's derived server-side, but it's no
+longer accompanied by the raw biometric values.

+# RuView Lovelace dashboards
+
+Drop-in Lovelace dashboard YAMLs for three common deployment shapes.
+Paste the contents of any file into HA's **Lovelace raw config editor**
+(Settings → Dashboards → ⋮ → Edit dashboard → ⋮ → Raw config editor)
+and edit the `binary_sensor.ruview_<room>_*` entity IDs to match what
+HA auto-discovered from your RuView nodes.
+
+| # | View                              | When to use                            |
+|---|-----------------------------------|----------------------------------------|
+| 1 | [Single-room overview](01-single-room-overview.yaml) | One RuView node, full 21-entity surface |
+| 2 | [Multi-node grid](02-multi-node-grid.yaml)            | 3+ RuView nodes (whole-house deploy)    |
+| 3 | [Healthcare / AAL view](03-healthcare-aal-view.yaml)  | Care-giver dashboard; **privacy-mode-safe** (no biometrics shown) |
+
+## Renaming entities
+
+RuView's MQTT auto-discovery generates entity IDs from the node's MAC
+address by default (`binary_sensor.ruview_aabbccddeeff_presence`).
+To get friendly names like `binary_sensor.ruview_bedroom_presence`,
+either:
+
+1. **Rename in HA** — open the entity, click the settings cog, change
+   the entity ID. HA stores the rename in its own DB; the MQTT
+   discovery topic stays the same.
+2. **Set `node_friendly_name`** in the sensing-server NVS config (per
+   ADR-115 §9.6 maintainer-ACK'd decision: NVS-only, no ADR-039
+   packet change). HA picks the friendly name up at next discovery
+   refresh.
+
+## Privacy-mode compatibility
+
+The third dashboard is designed for healthcare / AAL deployments where
+`--privacy-mode` is set on the sensing-server. Under privacy mode:
+
+- HR / BR / pose entities never reach HA (discovery is suppressed).
+- Semantic primitives (someone_sleeping, possible_distress, etc.)
+  continue to publish because they're inferred *states* server-side,
+  not biometric *values*.
+
+The healthcare dashboard binds only to semantic-primitive entities,
+so it remains useful — and HIPAA / GDPR-cleaner — under privacy mode.

+# This file suppresses advisories in two categories:
+#   A) CVE-bearing advisories in TRANSITIVE deps we cannot upgrade directly
+#      because the parent published crate (ruvector-core 2.2.0) has not yet
+#      published a version with the fix.  These are tracked as issues.
+#   B) UNMAINTAINED-only advisories (no CVE) flowing through dependencies

+#      surface in this workspace.

+# GTK3 / glib / gdk* family — RUSTSEC-2024-0411..0420, RUSTSEC-2024-0429
+# Reason: These crates are pulled in by wifi-densepose-desktop via Tauri v2's
+#   native WebView dependencies on Linux (libwebkit2gtk-4.1).  They are
+#   flagged as unmaintained because the GTK3 Rust bindings maintainers have
+#   moved to GTK4.  This codebase does NOT make direct use of any of the
+#   deprecated GTK3 APIs — the dependency is a runtime linker artifact of
+#   the Tauri Linux build.  Tauri itself is aware of this and will migrate
+#   when a GTK4-based Tauri backend is stable.  No CVE assigned.
+# Mitigation: Accept transitively until Tauri v2 drops GTK3 or a workspace
+#   override path becomes available.

ruv	62af91beb1	docs(readme): add 'What's new (2026-05-23)' callout for ADR-110 + ADR-115 Iter 50 — both ADRs merged today (PR #764 + PR #778). README's beta-software warning block was the natural location for a release callout above the main pitch; users hitting the README see today's shipped work first. Two-bullet block: - ADR-110 ESP32-C6 firmware substrate at v0.7.0-esp32 with the headline measured numbers (99.56 % match / 104 µs stdev / 3.95x EMA suppression) and the host-side surface (decoders + REST + Prometheus + WebSocket). - ADR-115 HA+Matter integration with the entity-count / blueprint / Lovelace count and the privacy-mode architectural win. Both link to their ADRs + PRs so reviewers can follow back. Co-Authored-By: claude-flow <ruv@ruv.net>	2026-05-23 16:19:44 -04:00
rUv	249d6c327f	ADR-115: Home Assistant + Matter integration (#778 ) Closes ADR-115's MQTT track (HA-DISCO + HA-MIND + HA-FABRIC scaffolding). Headline: - 21 entity kinds per node (11 raw + 10 semantic primitives) - MQTT auto-discovery with HA conventions - Matter Bridge scaffolding (SDK wiring deferred to v0.7.1 per ADR §9.10) - Privacy mode strips biometrics at the wire, semantic primitives keep working - 420+ lib tests, mosquitto-backed integration tests, property-based fuzzing - 8 starter HA Blueprints + 3 Lovelace dashboards shipped Tracking issue: #776	2026-05-23 16:13:28 -04:00
rUv	00a234eda8	ADR-110: ESP32-C6 firmware extension (#764 ) Closes the firmware-side ADR-110 design at v0.7.0-esp32 after a 38-iter /loop SOTA sprint. Headline (bench, COM9+COM12 ESP32-C6): - 99.56% cross-board RX, 104.1 µs smoothed offset stdev (≤100 µs §2.4 target met) - 3.95× EMA suppression, 1.4 ppm crystal skew preserved 4 firmware releases: v0.6.7 / v0.6.8 / v0.6.9 / v0.7.0-esp32. 42 ADR-110 unit tests, 1761 v2 workspace tests, full Firmware CI + QEMU green.	2026-05-23 15:34:48 -04:00
rUv	5d544126ee	fix(ui): unbreak viz.html — OrbitControls importmap, WS URL, toast NPE (#760 ) (#773 ) * fix(ui): unbreak viz.html — OrbitControls importmap, WS URL, toast NPE (#760) Three independent bugs were stacking to make ui/viz.html unusable from `main`: 1. Three.js r160 removed `examples/js/OrbitControls.js`, so the script-tag load 404'd and `new THREE.OrbitControls(...)` threw. Switch to an importmap that pulls the ES module build, then re-expose `window.THREE` and `THREE.OrbitControls` so the existing component modules (scene.js, body-model.js, …) keep working without a wider refactor. 2. The WebSocket client was hardcoded to `ws://localhost:8000/ws/pose`, but the sensing-server listens on `--ws-port` (8765 default, 3001 in the Docker image) at `/ws/sensing`. Reuse the existing `buildSensingWsUrl()` helper from `sensing.service.js` so port pairings are handled centrally, and add a `?ws=…` query-string override for non-standard setups. The websocket-client.js default is also updated to derive from `window.location` instead of the dead `:8000/ws/pose` literal. 3. `ToastManager.show()` called `this.container.appendChild(...)` even when `init()` had never been called, throwing a TypeError that killed the rest of page initialization. Auto-init the container lazily on first show (patch from issue reporter). Closes #760. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(ui): single module script + mutable THREE — OrbitControls validated Browser validation against the previous commit caught two stacked issues: 1. `import * as THREE from 'three'` returns a frozen Module Namespace Object — assignment `THREE.OrbitControls = OrbitControls` silently no-ops, so the global never gets the OrbitControls reference. 2. Two separate `<script type="module">` blocks (one installing the THREE global, one consuming it via Scene) are independently async-resolved. The second can finish dependency loading first and call `new THREE.OrbitControls(...)` before the first script has run. Fixed by spreading the namespace into a plain mutable object and merging all initialization into a single module script with `await import()` for component modules. Order is now strictly: import THREE → install window.THREE → import components → run init(). Validated via agent-browser: page logs `[VIZ] Initialization complete`, WebSocket targets the correct `ws://127.0.0.1:3001/ws/sensing` endpoint (derived from buildSensingWsUrl), toast lazy-init confirmed via eval.
