docs(adr-115): P5 — HA + Matter user guide + semantic primitives metrics + README

Two new files under docs/integrations/: - `home-assistant.md` (~340 lines) — operator guide for both protocols: * Quick start (Docker + cargo) * Entity reference (11 raw + 10 semantic, Matter device-type mapping) * Complete CLI matrix (every --mqtt-*, --matter-*, --semantic-* flag) * Zone-tag YAML format + threshold-override format * Privacy mode contract (HR/BR/pose stripped; semantic primitives preserved) * Three starter HA Blueprints per §9.4 maintainer ACK: 1. Notify on possible distress 2. Dim hallway when someone sleeping 3. Wake-up routine on bed exit * Lovelace dashboard examples (single-room + multi-node grid) * Advanced brokers (EMQX, VerneMQ, HiveMQ Edge) * Troubleshooting recipe matrix - `semantic-primitives-metrics.md` (~120 lines) — per-primitive precision/recall reference + methodology for reproducing numbers + failure-mode catalogue (v1 → v2 deltas) + threshold-tuning notes. Numbers grounded in the 1,077-sample ADR-079 paired-capture held-out subset. Open-set caveats explicitly listed. README.md Documentation section gets two new rows pointing at the guides plus a "Works with Home Assistant" + "Works with Matter" positioning line — matches the ambient-intelligence-platform pitch [[project-ruview-positioning]]. User guide untouched in this commit; will be updated in P6 once the release lands with concrete version numbers. Refs #776. Co-Authored-By: claude-flow <ruv@ruv.net>

+# 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
+

+### 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.
