Follow-ups from the epic-end /code-review of the E5 branch:
- tmdb.resolve_recs + people._resolve_known_for: match recommendations/
credits to the library bucketed by media_type. TMDB movie ids and tv ids
are independent sequences, so a bare `tmdb:<id>` match could deep-link a
movie rec to an unrelated show (or vice-versa) on a numeric collision.
Regression test added (test_resolve_recs_matches_by_media_type_not_bare_id).
- routes/search: wrap the _ingest_candidates call so a DB/enrich failure
degrades to a 422 with a message instead of a bare 500 hidden behind the
FE's generic "search failed" (extends the B-core-1 rationale); rollback on
failure. Stamp enriched_at with its own timestamp taken after the enrich,
not the stub-insert placeholder.
- routes/plex/discover: key serialized cards back by rating_key (globally
unique in Plex) instead of id(obj); fix the stale rows 3-tuple annotation.
A live smoke against the real TMDB API showed two crew problems the mocked
tests missed: (1) a TV show's creator/showrunner lives in the payload's
top-level `created_by`, not the crew list, so it was dropped entirely; and
(2) TMDB's crew order is arbitrary — a TV show's per-episode Directors (dozens)
flooded the key-crew list and buried the show-level roles.
Fix: split the accepted crew jobs by media type — movies key on
Director/Writer/…; TV keys on Creator (from created_by) + the show-level
Executive Producer/Writer/Producer/Composer, deliberately excluding the
per-episode Director/Editor/DP noise. Stored crew is sorted by display
priority and capped, so the lead roles come first.
Verified live: Breaking Bad -> [Gilligan (Creator), Johnson (EP), … , Writer];
The Godfather -> [Coppola (Director), Puzo (Screenplay), …]. test_plex_tmdb
green (9).
Matches each mirrored Plex movie/show to TMDB by its stored canonical guid,
fetches once (append_to_response), and PERSISTS the enrichment onto the row —
served from the DB, never a live TMDB call at serve time. Additive: the
Plex-sourced imdb_rating/rating are untouched; tmdb_rating is the distinct
TMDb community score (ratings scope = TMDb + Plex's IMDb/audience, no OMDb/RT).
- config.py: tmdb_api_key + api_base/language/interval/batch defaults.
- sysconfig SPECS: tmdb_api_key (secret, Fernet) + tmdb_language, auto-rendered
in the admin Config page; read like the Plex token.
- migration 0071 (ADD-only nullable, reversible): plex_items + plex_shows gain
tmdb_id / tmdb_enriched_at (watermark) / tmdb_rating / tmdb_vote_count /
budget / revenue / keywords / crew / studios / production_countries /
recommendations / backdrops; plex_people gains tmdb_person_id (the S2
foundation for S6 person bios). No watermark reset needed.
- app/plex/tmdb.py: TmdbClient (mirrors PlexClient; throttled; 404->None,
transient->TmdbError), parse_tmdb / apply_tmdb_detail (one-parser rule),
guid_to_tmdb_id (tmdb: direct, imdb:/tvdb: via /find), enrich_batch (movies
then shows, transient error leaves the watermark NULL to retry, definitive
no-match still stamps so it isn't re-fetched), _link_people (upserts
tmdb_person_id by name), serve_block (recommendations resolved to library
rows by guid), run_enrich (no-op without a key).
- scheduler: tmdb_enrich nightly job (default 120 min, no YouTube quota),
runtime-tunable + "run now" from the Scheduler dashboard.
- detail endpoints emit `tmdb` (movies + shows) so it's curl-verifiable now;
the FE render lands in S5.
Note: _link_people inserts plex_people rows for TMDB cast/crew; unreferenced
crew (composers etc., not in cast_names/directors) get pruned by the orphan
sweep — acceptable, the person page is cast-driven and cast rows survive.
Gate: ruff + py_compile green; backend test lane FULL suite 387 passed
(incl. migration drift downgrade->re-upgrade + test_plex_tmdb 9 tests).
Frontend unchanged since S1. Not merged (epic branch, stacks on S1).
