Lands the remaining six §3.12 v1 primitives:
- `distress` (PossibleDistress) — EWMA baseline HR + 1.5× multiplier
+ agitated motion + no-fall + 60 s dwell → ON. Refractory 5 min
after exit. Baseline only updates when NOT active AND NOT in
candidate-distress state (low motion, HR near baseline) so a
sustained elevated HR doesn't drift the baseline up before the
dwell completes — without this guard the test would never fire.
- `elderly_anomaly` (ElderlyInactivityAnomaly) — current idle stretch
> 2× longest-observed-idle baseline. Baseline floor at 30 min so
the first day doesn't fire spuriously. 24 h refractory per resident.
- `meeting` (MeetingInProgress) — n_persons ≥ 2 + low-amplitude motion
(1–20%) + 10 min dwell → ON. 2 min exit dwell on count drop.
- `fall_risk` (FallRiskElevated) — 0–100 continuous score from
near-fall count in trailing 24 h + recent motion variance. Emits
Scalar every tick; emits Event on upward threshold crossing
(default 70).
- `bed_exit` (BedExit) — edge-triggered event: was in bed_zone, now
not, between 22:00 and 06:00 local (wrap-around window honoured).
- `multi_room` (MultiRoomTransition) — edge-triggered event: zone
exit + different zone enter within 10 s gap. Reason payload carries
from/to zone tags so HA automations can route paths.
Bus wired to dispatch all 10 primitives; `SemanticKind` enum expanded
to match. `tick()` returns up to 10 events per snapshot.
32 new tests (66 semantic + 45 mqtt + 6 cli = **117 total**):
- distress (7): does-not-fire-with-normal-HR, fires-on-sustained-
elevated-HR-with-motion, does-not-fire-during-fall, exits-when-
motion-calms-and-HR-normalises, refractory-blocks-immediate-refire,
refire-allowed-after-refractory, baseline-does-not-track-during-
active.
- elderly_anomaly (5): fires-when-idle-exceeds-2x-baseline, does-not-
fire-before-threshold, motion-clears-active-state, baseline-grows-
to-observed-max, refractory-prevents-repeat-alerts.
- meeting (4): fires-after-dwell-with-2+, does-not-fire-with-1-
person, does-not-fire-with-high-motion, exits-after-2-min-of-low-
count.
- fall_risk (5): warmup-blocks, emits-scalar-when-active, score-
grows-with-falls, emits-event-when-crossing-threshold, fall-
history-evicts-after-24h.
- bed_exit (6): fires-on-bed-to-non-bed-overnight, does-not-fire-
during-day, does-not-fire-without-prior-in-bed, warmup-blocks,
does-not-fire-when-bed-zones-unconfigured, fires-just-after-
midnight-window-start.
- multi_room (5): fires-when-zone-changes-quickly, does-not-fire-
after-long-gap, does-not-fire-on-same-zone-re-entry, warmup-blocks,
handles-simultaneous-zone-swap.
ADR-115 §3.12 inference layer now complete. Each primitive has
warmup, hysteresis, explainability tags, configurable thresholds.
Adding a v2 primitive is one file + one bus entry.
