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).
Per-zone declarative safety rules, set in the zone editor and enforced on the
edge from the tracking the pipeline already does (no new geometry, no new model):
- min_workers (2인 1조): 0 < count < minimum sustained 30s -> lone_worker/HIGH.
A solo worker in a buddy-rule zone is a compliance violation and a rescue-
delay risk, so it outranks the other two.
- max_workers: count > limit sustained 10s -> overcapacity/WARNING.
- max_dwell_s: one track's continuous stay past the limit -> overstay/WARNING.
A short detection dropout (<=5s grace) does NOT reset the dwell timer -
without that, run_once's stale-track filter would quietly neuter every
10-minute rule at real-world detection rates.
Edge: detectors/occupancy.py consumes Zone.rules; the engine flips the zone
detector's per-track membership into per-zone headcounts (stale tracks already
excluded), so counts always match what was actually detected this tick. Fired
states clear on condition recovery - re-alerts need a fresh violation, not a
cooldown expiry. Malformed rules_json keeps the zone's intrusion detection
alive and logs the rules as inactive (never fail dark).
Server: move_zones.rules_json (nullable JSON, migration included) validated
strictly in ZoneConfigController (bounds, min<=max, unknown keys rejected -
a silently dropped rule is one the operator believes is active). Delivered to
the edge unchanged via GET /api/config. EventValidator accepts the 3 new types.
UI: zone editor gains the three rule fields (dwell entered in minutes, wired
in seconds) and shows each zone's rules in its list row; the events console
and detail view now render every event type in Korean (wire codes fall back).
Verified: pytest 216 pass / PHPUnit 123 pass + real-render harness in Chrome
(editor save payload, list labels, console type labels).
- Rail rework: the flat device strip + camera <select> becomes one device->camera
tree (device-tree.js owns the DOM). A device row carries the heartbeat verdict
(online/offline, fps, temp, throttle, config drift); the cameras seen in the
event stream nest under it and double as the stream's camera filter.
- The camera filter is a (device, camera) PAIR: camera ids are free-form edge
strings, so two devices may both run a "cam-01" - one device's events no longer
leak into another's filtered view. Clicking the selected camera (or 전체 보기)
clears the filter.
- A camera whose device is missing from /api/devices renders as its own
unknown-device group ("장치 목록에 없음 - 등록 확인") instead of being dropped.
- Offline rows show liveness only - fps/temp are the LAST values a dead device
reported and would read as current telemetry.
- Poll-failure staleness, collapse state, and focus survive the 5s re-render;
an unchanged poll never rebuilds the DOM (render signature).
- Stream rows: device NAME + mono camera id + compact 24h stamp (year only when
not current); thumb slot links to the incident and is honest about 무영상 for
screen readers; KPI strip captioned "미확인" once.
Verified: PHPUnit 119 pass (4 skipped, PDO gate) + real-render harness in Chrome
(tree states, pair filter, collapse, reset, no console errors).
Rework the events dashboard from the sparse light-minimal look (which read as
empty / unprofessional) into a professional, information-dense operations
console — keeping the LIGHT direction (the dark HMI was previously rejected).
- App shell: top bar with an "AI SAFETY CCTV" brand mark + product identity, and a
device/camera rail (a second neutral layer) beside the detection stream.
- Density: device health + filters move into the rail; the four hero KPI cards
become a compact inline pill strip; the stream is snapshot-forward.
- Every event row is a camera slot (evidence thumbnail, or a "무영상" placeholder)
so the stream reads as a CCTV grid and rows stay aligned regardless of snapshots.
- Restrained near-monochrome; indigo for interaction only; severity colour spent on
the unacknowledged-critical alarm only; contrast-checked ink; reduced-motion honoured.
- Pure CSS, system fonts, zero external assets (air-gap). DOM contract (ids/classes)
unchanged, so polling/ack/alarm/filter logic is untouched. Verified in-browser.
- 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.
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.
