Review fixes for #1506.
- Ottawa: use the documented camera list and the city's Traffic Camera
Images API. The pack is skipped with no request unless
OTTAWA_CAMERA_CERTIFICATE is set; the certificate is added only at
fetch time inside the pinned /opendata/ path, and each camera is
fetched at most once a minute through the shared frame cache.
- Québec 511 video is opt-in (CCTV_QUEBEC_VIDEO_ENABLED=1) and loads
only after the viewer presses Play; selection, auto-hop, scenes and
voice no longer contact Québec 511. Credit splits locations (MTQ,
CC BY 4.0) from video (Québec 511). Interrupted play() is no longer
reported as an unavailable source; the per-frame listener runs only
while a Québec camera is selected and the canvas rect is cached.
- Catalog cap: reserved Québec and World slots come only from capacity
above the 4,000 shared slots, so a lower CCTV_MAX_SOURCES thins every
pack instead of starving the existing ones. dev-fresh and
.env.example default to 7,516.
- Throttled frames (World, Ottawa): inside the refresh floor with no
cached frame the proxy serves the placeholder, never Street View; a
failed fetch backs off for a minute; the cache is bounded by bytes.
- MJPEG first-frame extraction runs only for sources registered as
MJPEG (Taiwan Highway Bureau), caps a frame at 2 MB, reads in linear
time, accepts a CRLF preamble and a boundary that already starts with
"--", and ends a part without Content-Length at the next delimiter.
THB hosts are registered in the redirect pin list.
- Tests: World loader policy, Québec loader and opt-in, proxy cooldown
without Street View, Ottawa signing, cap reservations at 7,516, 4,000
and 48, overlay Play gate, refresh, visibility and teardown. Guard
tests check the 4,000 shared slots again.
- Remove the unused standalone Québec preview module and public page.
- Docs: DATA_SOURCES, SECURITY, CURRENT-STATE, CCTV_INTEGRATION, README,
.env.example, changelog fragment renamed to its full scope.
