Backlog for the TMDB subsystem produced by a multi-agent audit that
cross-checked our code against the official API reference and against how
Plex/Jellyfin/Emby/Stremio/Kodi present metadata: unused API surface,
zero-extra-call wins already sitting in cached payloads, effort-ranked
themes, a top-8 shortlist, implementation sketches, and an explicit
"deliberately not building" section with reasons.
Three entries are defects in shipped code rather than features and are
sequenced first: a broken provider tmdb_id suppresses enrichment
entirely, series cast is latest-season-only (needs aggregate_credits),
and cache retention exceeds the six-month TMDB ToS limit.
