The feedback loop, per product decision (option a): tags feed STATISTICS only.
A human reads the rate and re-tunes a camera deliberately - the tag never
adjusts edge sensitivity on its own (no silent behavior change in a safety
system).
- POST /events/{id}/false-positive: same RBAC ('acknowledge') + CSRF + site
scope as ack. Tagging also acknowledges (an FP is a handled event - leaving
it unacknowledged would keep it alarming). COALESCE keeps the FIRST tagger:
a second tag never rewrites who made the original audit-relevant call.
- move_events.false_positive_by/at (migration included), audit-logged.
- GET /api/fp-stats?days=N: per-(camera, event_type) totals + FP counts,
FP>0 groups only, fp-desc, fail-closed site scoping.
- Console: each open row gets a visually-secondary 오탐 button beside 확인
(can't be fat-fingered as the default); resolved rows show a mono verdict
("오탐 (user)" struck through vs "확인됨 (user)"). New rail panel "오탐율 ·
30일" lists top offenders - 30%+ highlighted as re-tuning candidates -
refreshed on a slow 60s cadence plus immediately after a tag. Detail view
shows the tag.
Verified: PHPUnit 135 pass / pytest unchanged + Chrome real-render (tag ->
row flips to struck-through verdict + drops out of unacked KPI/tree counts ->
FP panel updates immediately; no console errors).
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).
- Device-status panel (DeviceStatusController): site-scoped liveness over stored
heartbeat telemetry. Fix config_drift false-positive by storing NULL until the
device actually reports a version (was firing "설정 미적용" on every device).
- Zone save rejects a blank/unknown device_id (DeviceRepository::exists) so a zone
is never persisted against a device that will never fetch it.
- Snapshot proxy sends immutable private cache headers, ending the 5s-poll
re-download of every thumbnail (a Cafe24 traffic-cap hazard).
- Event list: paged-in acknowledgements stick; honesty affordances for the paging
gap, a stale device poll, and a filtered camera aging out; logout wired for
every page via the shared layout.
Drawing hazard zones on a blank canvas meant guessing pixel coordinates.
The editor can now pull the camera's most recent snapshot and draw over
what the camera actually sees.
- SnapshotRepository::latestForCamera() (+ Pdo/in-memory impls), ordered by
snapshot_id, not the device-reported occurred_at (a skewed Pi RTC would
otherwise pin 'latest' to a stale frame)
- GET /api/cameras/{camera}/latest-snapshot -> {uuid}; returns only the id,
the bytes still go through SnapshotProxy's session + site-scope check.
Out-of-scope and missing both 404, so a scoped operator cannot probe for
another site's cameras
- ix_events_camera (camera_id, event_id) so the lookup is not a full scan
- '현재 화면 불러오기' button in the zone editor
Tests: PHP 113 pass (4 skipped, 4 new), pytest 174 pass.
The PHP app runs on Cafe24 shared web hosting -- calling it 'cloud'
was misleading. Renames the directory, the edge client module, and
every doc/script/identifier that used the term.
- cloud/ -> server/ (incl. server/deploy/build_cafe24_package.sh paths)
- edge/cloudclient.py -> edge/serverclient.py, CloudClient -> ServerClient
- cloud/docs/cloud-deploy.md -> server/docs/server-deploy.md
- CLOUD_* env/config keys -> SERVER_*
- tests renamed to match
Tests: PHP 109 pass (4 skipped), pytest 167 pass. dist/ regenerated.
