feat(cog-ha-matter): P2 scaffold + ADR-116 P1 research-dossier fold-in
cron iter 1. Three things landed atomically because they cross-cite:
P1 — research dossier complete
Deep-researcher agent (a4dd35950ffd) shipped
docs/research/ADR-116-ha-matter-cog-research.md: 8 sections,
30+ citations across Matter / HACS / cog arch / local-AI /
federation / competitors / regulatory / v1 scope. Key
findings folded into ADR-116 §3 and §4:
- Matter device class: OccupancySensor (0x0107) +
RFSensing feature on cluster 0x0406 (1.4 rev 5)
- ESP32-C6 Thread Border Router: one Kconfig flag away
(CONFIG_OPENTHREAD_BORDER_ROUTER=y)
- HACS quality tier: target Gold (repairs + diagnostics +
reconfiguration), start from hacs.integration_blueprint
- CSA cert: ~$30-42k/yr — skip for v1, "Works with HA"
positioning instead
- Cog RAM/CPU: 128 MB / 15% on the Seed; 10 KB INT8
semantic-primitive classifier fits without PSRAM
- SONA: <100 µs/query confirmed by ruvllm-esp32 v0.3.3
- FDA Jan 2026 wellness guidance covers HR / sleep / activity
anomaly when marketed as "anomaly notification" not "diagnosis"
- Competitor moat: Aqara FP300 / TOMMY / ESPectre all lack
HR + BR + pose + semantic + witness simultaneously
P2 — cog crate scaffold compiles
v2/crates/cog-ha-matter/ created with cog-pose-estimation as
precedent shape (ADR-101). Files:
- Cargo.toml: depends on wifi-densepose-sensing-server with
--features mqtt + wifi-densepose-hardware for the ADR-110
SyncPacket bridge.
- src/lib.rs: COG_ID = "ha-matter", MDNS_SERVICE_TYPE
"_ruview-ha._tcp", DEFAULT_CONTROL_PORT 9180.
- src/manifest.rs: typed CogManifest (8 fields) mirroring
cog-pose-estimation's manifest.template.json. Round-trip
test locks the JSON wire shape; id-constant test guards
against rename drift.
- src/main.rs: clap CLI with --sensing-url / --mqtt-host /
--mqtt-port / --privacy-mode / --print-manifest. The
--print-manifest flag emits the build-time template with
{{VERSION}} / {{ARCH}} placeholders for the signer.
- v2/Cargo.toml: cog-ha-matter added as workspace member.
Verification:
cargo check -p cog-ha-matter --no-default-features → green
cargo test -p cog-ha-matter --no-default-features --lib
→ 2/2 manifest tests pass
ADR-116 §3 + §4 + §5 (phases) updated to mark P1+P2 ✅ done and
seat the recommended v1 scope (privacy-mode audit-only → cog
signing → SONA loop → HACS gold → Matter Bridge as v0.8) ranked
by build cost × user impact per the dossier.
P3 (next iter): wrap the existing ADR-115 MQTT publisher as the
cog's main loop. The scaffold returns SUCCESS immediately today.

|
|||
|
||||
The federation model is the natural extension of ADR-110's mesh substrate into the application layer. Specifically: ADR-110 gives us ≤100 µs cross-board sync; this ADR uses that to deduplicate cross-Seed events (one fall, one alert) and reconstruct multi-room transitions (one occupant, room A → hallway → room B).
|

|
||||
## 3. Open questions (research dossier will answer)
|
||||
## 3. Research dossier findings (P1 complete)
|
||||
|
||||
1. **Matter Bridge vs Matter Root** — can the Seed act as a commissioner, or is Bridge mode the only realistic 2026 option?
|
||||
2. **Thread Border Router** — does the ESP32-S3 in the Seed (or a paired ESP32-C6 node) host a Thread Border Router cleanly, and does that buy us anything HA users care about?
|
||||
3. **HACS integration value-add** — beyond MQTT auto-discovery, what does a custom HA integration unlock? (config flow / repairs / device-class custom entities / service catalog).
|
||||
4. **CSA certification cost / timeline** — what's the minimum CSA-compliant subset and what does it cost to ship a CSA-certified Matter device today?
|
||||
5. **Cog binary size + Seed RAM budget** — the Seed has 8 MB PSRAM + 320 KB SRAM. The cog must fit.
|
||||
6. **ruvllm + RuVector latency for semantic primitives** — can the 10 inferred states run at 5 Hz on the Seed without external compute?
|
||||
7. **HIPAA / FDA classification** — when does fall-detection cross into regulated medical-device territory, and does the `--privacy-mode` strip + Matter Health device class give us a defensible "wellness device" position?
|
||||
Full dossier: [`docs/research/ADR-116-ha-matter-cog-research.md`](../research/ADR-116-ha-matter-cog-research.md). The eight research questions are now answered:
|
||||
|
||||
1. **Matter Bridge vs Matter Root** — Matter 1.4 introduced `OccupancySensor (0x0107)` with `RFSensing` feature flag on cluster `0x0406` (revision 5 in Matter 1.4). That's the correct device class for WiFi-CSI sensing — no health/vitals cluster exists in Matter 1.4.2 and won't soon. **Seed acts as Bridge** with N dynamic OccupancySensor endpoints, **not Commissioner** (the C6 sensing nodes stay Accessories only — 320 KB SRAM no PSRAM rules out commissioning).
|
||||
2. **Thread Border Router** — ESP32-C6 single-chip TBR confirmed working; `CONFIG_OPENTHREAD_BORDER_ROUTER=y` is the only config step. ADR-110's `c6_timesync.c` already initialises 802.15.4 — TBR is a Kconfig flag away. Real value: HA's Improv-style commissioning works without a separate Thread border router box.
|
||||
3. **HACS value-add** — config flow (UI setup wizard), Repairs API (structured error cards), re-authentication, diagnostics download, typed service actions (`set_privacy_mode`, `calibrate_zone`), i18n translations. **Bronze is the minimum bar; Gold (repairs + diagnostics + reconfiguration) is the target.** Start from `hacs.integration_blueprint` template.
|
||||
4. **CSA certification** — ~$30-42k first year ($22.5k membership + $10-19k ATL lab fees). **Skippable for v1** by publishing as "Works with HA" instead. CSA re-evaluate at v0.9+ after HACS adoption data lands.
|
||||
5. **Cog RAM budget** — 128 MB RAM / 15 % CPU on the Seed appliance (Pi 5 + Hailo-10 variant has more headroom). 10 KB INT8 semantic-primitive classifier fits without PSRAM. Long-lived supervised process with capability scopes `network.mqtt + network.matter + api.ruview_vitals`.
|
||||
6. **ruvllm + RuVector latency** — `ruvllm-esp32` v0.3.3 confirms SONA self-optimising adaptation under 100 µs per query. 8→10 INT8 classifier ~10 KB quantised. Per-home threshold tuning via HA thumbs-up/thumbs-down feedback as LoRA-style gradient steps — closes the top user complaint (false positives) without cloud round-trips.
|
||||
7. **HIPAA / FDA** — FDA January 2026 General Wellness guidance explicitly classifies HR / sleep / activity-anomaly alerts as **wellness devices** (outside FDA jurisdiction) when marketed without diagnostic claims. Frame fall detection as **"activity anomaly notification"** not "fall diagnosis". `--privacy-mode` audit-only tier (no MQTT state messages, only SHA-256 digests on-Seed) creates a technical PHI barrier. `OccupancySensor (0x0107)` device class keeps the product in the same regulatory category as a smart motion sensor.
|
||||
8. **Competitor moat** — Aqara FP300 (Nov 2025): 5 entities, no person count, no vitals, no fall detection. TOMMY: zones only, no vitals, closed-source, paywalled. ESPectre: motion only. **RuView's differentiation** — HR/BR + 17-keypoint pose + 10 semantic primitives + witness chain + SONA adaptation — has no competitor equivalent.
|
||||
|
||||
## 4. Recommended v1 scope (from dossier §8)
|
||||
|
||||
Ranked by build cost × user impact:
|
||||
|
||||
| # | Feature | Cost | Impact | Phase |
|
||||
|---|---|---|---|---|
|
||||
| 1 | **`--privacy-mode` audit-only tier** (no MQTT state, SHA-256 digests on-Seed) | ~1 week | Closes care / GDPR deployments | P3 (this cog) |
|
||||
| 2 | **Seed cog manifest + Ed25519 signing + store listing** | ~1-2 weeks | Enables one-click distribution | P2 + P8 (this cog) |
|
||||
| 3 | **Local SONA fine-tuning loop** (HA feedback → LoRA gradient steps) | ~2-3 weeks | Reduces false positives, closes #1 user complaint | P5 (this cog) |
|
||||
| 4 | **HACS gold-tier integration** (config flow + repairs + diagnostics) | ~4-6 weeks | Removes MQTT prerequisite for mainstream users | P9 (separate repo `hass-wifi-densepose`) |
|
||||
| 5 | **Matter Bridge with OccupancySensor + dynamic endpoints** | ~6-8 weeks | Apple Home / Google Home / Alexa native | **v0.8** dedicated sprint (after HACS adoption data) |

||||

//! ADR-116 — Home Assistant + Matter Cognitum Seed cog.

//!
|

//! This crate is the Seed-installable wrapper around ADR-115's
|
||||
//! `wifi-densepose-sensing-server::mqtt` publisher. It adds the
|
||||
//! Seed-native surfaces ADR-115's `--mqtt` flag can't easily reach:
|
||||
//!
|
||||
//! 1. **mDNS service advertisement** — `_ruview-ha._tcp` so HA discovers
|
||||
//! the cog automatically (no manual broker host/port config).
|
||||
//! 2. **Optional embedded MQTT broker** — for Seeds running without an
|
||||
//! external mosquitto. Defaults to off; the cog can either embed
|
||||
//! rumqttd or connect to a user-provided broker.
|
||||
//! 3. **RuVector-backed semantic-primitive thresholds** — replaces
|
||||
//! static `semantic-thresholds.yaml` with a SONA-adapted RuVector
|
||||
//! inference. Per-home thresholds learned from the Seed's own
|
||||
//! long-term observation stream.
|
||||
//! 4. **Ed25519 witness chain** — every state transition signed so
|
||||
//! regulated deployments (healthcare, education, shared housing)
|
||||
//! have a tamper-evident audit log.
|
||||
//! 5. **Multi-Seed federation** — peer discovery via mDNS + cross-Seed
|
||||
//! event deduplication keyed on ADR-110's ≤100 µs mesh-aligned
|
||||
//! timestamps. One fall in a shared room emits one alert, not N.
|
||||
//! 6. **OTA firmware coordination** — the cog manages C6 firmware
|
||||
//! rollouts for ESP32-C6 nodes in the local mesh.
|

//!
|
||||
//! The cog binary entrypoint is in `bin/main.rs`. Library modules
