Expose the maintenance job's rolling re-validation batch (videos re-checked per
run) as an admin control on the Scheduler dashboard, stored in app_state
(migration 0018; NULL = the env/config default). The job reads the effective
value each run via a state helper, clamped to a sane range. Trilingual.
- uvicorn --log-config (log_config.json): timestamped formatters for uvicorn
access/error and the app's own "subfeed" loggers (ms precision)
- Log key activity: startup/shutdown, login/denied, token refresh, YouTube API
errors, subscription imports, sync pause/resume
- Background sync jobs no longer swallow errors silently — failures in RSS poll,
backfill, enrichment, autotag and resync are logged with tracebacks
- Header shows a live sync status (total videos + channels still backfilling, or
"paused"), polled every 30s
- Admins can pause/resume the background sync; a paused flag in app_state makes
scheduled jobs skip (migration 0006)
- GET /api/feed/count returns the number of videos matching the current filters;
shared filter builder keeps it in sync with /api/feed; shown above the feed
- /api/sync/status reports backfill progress, pending enrichment and paused state
