Server (Plex/Jellyfin) is the source of truth, so every scanned row carries
(server_source, server_id) for upsert + stale-removal — mirroring how music
keys on server_source + ratingKey.
- schema: server_source/server_id columns on movies/shows/episodes (+ server_id
on seasons); unique (server_source,server_id) on movies/shows (multiple NULLs
allowed so wishlist rows never block).
- VideoDatabase.upsert_movie / upsert_show_tree: take normalized, server-
agnostic dicts (a Plex/Jellyfin adapter produces them — DB never touches a
media SDK), set has_file + media_files, and prune episodes/seasons the server
no longer reports.
- prune_missing(): removes top-level movies/shows the scan didn't see (cascades
clean children).
6 new tests (insert/update/file-replace, season/episode build+prune, top-level
prune); 18 video-DB tests green.
Separate SQLite file (database/video_library.db, env VIDEO_DATABASE_PATH),
fully disconnected from music — never imported by music, imports nothing from
music, no shared write lock.
Schema (database/video_schema.sql), designed to dodge the music DB's known
pain points:
- movies; shows->seasons->episodes; channels->channel_videos (YouTube as a
first-class peer); media_files (the library); downloads (queue+history);
activity feed; root_folders / quality_profiles / video_settings config.
- No polymorphic ids: media_files/downloads use separate nullable FKs + a CHECK
that exactly one owner is set; real cascades.
- Explicit external-id columns (tmdb/tvdb/imdb/youtube), no source-id blob.
- Watchlist/Wishlist/Calendar are DERIVED VIEWS over monitored + file state
(single source of truth, can't drift like music's wishlist table did).
VideoDatabase mirrors music's conventions (WAL, foreign_keys ON, 30s busy
timeout, Row factory, once-per-process init, user_version backstop) but is an
independent implementation. 13 seam tests: schema builds, CHECK constraints
reject bad rows, cascades fire, views return correct membership, KV roundtrips,
and a guard that the module imports nothing from music.
