First of the new enrichment services, wired to the SAME standard as the rest:
- TraktWorker backfill (core/video/enrichment/backfill.py): looks a title up by its
IMDb id (?extended=full) and gap-fills the community rating + vote count. Registered
in build_backfill_workers.
- DB: trakt_rating/trakt_votes/trakt_status/trakt_attempted columns + _BACKFILL /
_BACKFILL_COLS registration; detail payloads return trakt_rating/votes.
- Connections tab: Trakt service frame (Client ID field + Test button), wired into
video-settings.js load/save/bindings and the /enrichment/config GET+POST.
- Worker-manager modal + orb: WORKERS registry entry (red ★) + status-poll SERVICES
list, so it gets the same orb animation + per-service matched/pending/error card.
- Detail page: a 'Trakt 8.2' rating chip alongside IMDb/RT/Metacritic (+ CSS).
5 new tests + 2 fixed-set assertions updated; 249 video tests green, ruff clean.
Adds a VideoBackfillWorker base that enriches already-identified items BY id
(vs the matcher workers), with the exact same lifecycle + get_stats() shape so
the engine registry, /api/video/enrichment routes, and Manage-Workers modal
drive them identically.
Workers:
- fanart.tv (free key): gap-fills logo/clearart/banner/backdrop/poster art
- OpenSubtitles (free key): records subtitle-language availability per title
- Return YouTube Dislike (no key): like/dislike estimates on cached videos
- SponsorBlock (no key): crowd segments per video
DB: youtube_video_stats + youtube_video_segments tables; fanart/subs columns;
backfill_next/mark/breakdown + youtube_enrich_* helpers; likes/dislikes merged
into get_channel_videos. Seam tests in tests/test_video_backfill.py.
