Heinrich's-law play: the signals we already compute but used to throw away
become a spatial risk map of the workplace, drawn over the camera's own frame.
Edge:
- near_fall (INFO): a track that reached FALLING (sustained prone) but recovered
before the FALLEN confirm. Treated as a full event per product decision -
same ingest, snapshots, dedup, ack flow as incidents. Fix en route: prone_s
used a truthiness check that turned prone_since=0.0 into "no timer".
- Every per-track event (fall/no_motion/near_fall/immobility/zone hits) now
carries the foot point in the zones' normalized 0..1 space (reusing the zone
detector's own coordinate math); ghost's pixel-space loss point is normalized
at emit. to_payload omits the key when absent, so an old server ignores it.
Server:
- move_events.spatial_x/spatial_y (nullable DOUBLE) + validator: optional
[x, y] finite-number pair; range deliberately NOT enforced (an off-by-a-hair
foot must never reject a FALL alert - renderers clamp).
- MIGRATION FIX: chk_events_type would have REJECTED the previous commit's
lone_worker/overcapacity/overstay inserts on MySQL 8.0.16+ - the constraint
is rebuilt with all 13 types (incl. near_fall).
- GET /api/heatmap/{camera}?days=N (1..90, default 30, 5000-point cap):
spatial points with the same fail-closed site scoping as the event list.
UI (zone editor): "위험 히트맵" toggle + day window. Additive radial blots in
an offscreen layer under the zone polygons; severity weighs the alpha so a
cluster of near-misses reads lighter than one confirmed fall at the same spot.
Events console/detail label near_fall in Korean.
Verified: pytest 222 pass / PHPUnit 130 pass + Chrome real-render (blue
near-miss cluster + red incident hotspot inside the restricted zone, amber
cluster in the warning zone, zones drawn on top; no console errors).
