From 8e416af2035580866ef697a7cb12f13a154fdfc9 Mon Sep 17 00:00:00 2001 From: ruv Date: Sat, 23 May 2026 14:01:51 -0400 Subject: [PATCH] =?UTF-8?q?feat(adr-115):=20P4.5a=20=E2=80=94=20semantic?= =?UTF-8?q?=20inference=20layer=20(HA-MIND)=20=E2=80=94=204=20primitives?= =?UTF-8?q?=20+=20bus=20(34=20tests)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ADR-115 §3.12 keystone. Raw signals are not the product — customers want first-class entities like `binary_sensor.bedroom_someone_sleeping`, not a Node-RED flow that thresholds breathing rate at night. This commit lands the inference layer that turns the broadcast channel into 10 v1 semantic primitives, starting with the 4 highest-leverage ones. Modules: - `semantic::common` — `RawSnapshot` projection, `PrimitiveState`, `PrimitiveConfig` (thresholds matching the v1 catalog in ADR §3.12), `in_window` for time-gated primitives, `Reason` explainability struct. - `semantic::sleeping` — SomeoneSleeping FSM: presence + motion<5% + BR ∈ [8,20] bpm + 5min dwell. Exit on presence-drop (immediate) or motion>15% for 30s. - `semantic::room_active` — motion >10% in 30s window → ON. Exit on presence-drop or 10min idle. - `semantic::bathroom` — presence + zone tagged as bathroom. Safe in privacy mode (no biometrics in the derivation). - `semantic::no_movement` — presence + motion<1% for 30min → ON. Safety-check primitive for aging-in-place. - `semantic::bus` — single dispatch that runs all primitives on each `RawSnapshot`, returns a list of `SemanticEvent`s for MQTT+Matter publish. Every primitive has: - Warmup suppression (60s default, §3.12.4) - Hysteresis (enter + exit thresholds different) - Explainability via `Reason::new(&["motion<5%", "br=12bpm", ...])` - Configurable thresholds via `PrimitiveConfig` Test coverage (34 tests, all passing under `--no-default-features`): - common: in_window simple + wrap-around midnight, default thresholds match ADR catalog, Reason struct. - sleeping (7 tests): warmup blocks, fires after dwell, no-fire on high motion, no-fire on BR out of range, exits on presence-drop immediately, exits on sustained motion only after 30s, brief blip does not exit. - room_active (6 tests): warmup, fires on high+presence, no-fire without presence, no-fire below threshold, exits on presence-drop, exits on extended idle. - bathroom (5 tests): fires on zone match, ignores other zones, requires presence, warmup blocks, emits OFF on zone exit. - no_movement (4 tests): fires after dwell, no-fire with motion, brief motion resets timer, exits on motion. - bus (6 tests): empty during warmup, emits room_active, emits bathroom, multiple simultaneous primitives, event carries node_id+ts, reason populated for HA debug. Total cargo test count now: cli: 6 + mqtt: 45 + semantic: 34 = 85 tests passing P4.5b (next iteration) lands the remaining 6 primitives: distress (HR multiple over baseline), elderly_anomaly (long-window inactivity), meeting (multi-person dwell), fall_risk (gait instability score), bed_exit (sleeping → presence-out between 22:00-06:00), multi_room (track_id continuous across zones).
