Backend (c2-core):
- app/internal/cameras/: provider interface, licence model, per-provider
catalog cache; one adapter per source in design-canvas/camera-sources.md.
Implemented: 511NY (legacy shape + tolerant XML inventory parser, 511x
endpoints UNVERIFIED), Caltrans, DelDOT, Ontario 511, DriveBC, Calgary,
TfL, NSW, Fintraffic. Stubs: NYC DOT, Westchester DPW, TRANSCOM, CTroads,
511NJ, Austin, TxDOT, MD CHART, WSDOT, Tallinn, Tarktee, Warendorf,
TrafficLand, Windy, EarthCam.
- Every provider defaults OFF (config/camera_providers). Gated licences
(agreement required / unverified / non-commercial / paid) need an explicit
acknowledgement stored with who/when and written to audit_log; the audit
write is a precondition. Stubs and prohibited sources cannot be enabled.
Ack is bound to the licence status it was given for.
- GET /cameras (signed-in), GET/PUT /admin/camera-providers (admin only).
- /traffic/511 follows the ny511 provider switch and returns the DAA credit
+ NYSDOT as-is disclaimer; 511NY event descriptions no longer truncated
("may not alter the substance of a report").
Frontend:
- LiveView becomes the ops wall: Region > Incident > Camera drill-down,
worst-first rail (MapView), KPIs, transcript ticker, scrubber incident
bands, auto-tour, deep links (#inc=&cam=&tour), Esc steps up.
- Incident panel: nearest cameras (path-weighted), fused situational context
(ADS-B, AIS, 511NY events, NEXRAD tile sample), units, call spine.
- MapView keeps every layer; adds Camera Viewsheds (approx.) overlay and a
nearest-camera layer for the selected incident.
- CameraFeed hygiene: hidden-tab/off-screen gating, 2 concurrent HLS cap,
last good frame + stale badge, frozen-frame signature, HLS stall watchdog,
provider attribution rendered on the imagery.
- Camera/event popups show source credit, update time and the disclaimer.
- Admin > Camera providers tab with licence status, health, gated confirm.
- Camera detection is not built (blocked on #199/#200); seam only.
