The skill still described archived upstream v26.3.0: "MediatR + Blazor (not
REST for mutations)", "No REST CRUD for channels/collections/schedules —
must use SQLite DB directly", and the ghcr.io image. All false for this
fork — Blazor was removed in #91b and /api/v1 has full write paths. A
session trusting it would hand-edit SQLite for something the API does.
Also adds what this session had to discover by hand while driving the API:
the key is root-owned so an unsudo'd read fails SILENTLY (empty header ->
401 body that parses as a dict -> a naive script reports "0 channels"
rather than an auth error); settings live at /api/v1/settings/ffmpeg, not
ffmpeg/settings; test is port 8410 and the service-scoped manual refresh
command for validating before the 03:00 auto-update.
Two measurement traps recorded with them: OCI labels are inherited from the
linuxserver base image and lie about what is running (compare .Image to the
registry Docker-Content-Digest), and container log brackets are local time
while `docker logs -t` is UTC, so --since windows mis-slice.
Endpoint lists now defer to docs/endpoint-index.md rather than being
re-maintained here, since a hand-copied list is what drifted in the first
place.
