E5 S6 backend half (no migration — the *_hu / rich columns exist from S5a/S5b).
Language-aware serving (?lang=hu serves the HU overlay twin, EN fallback per row):
- query.py: column pickers title_col / genres_col / vector_col; field_recheck and
meta_filter_conds take `lang`. DISPLAY/FILTER pickers coalesce(*_hu, *) (EN
fallback); SEARCH pickers use the raw *_hu column mirroring the generated
search_vector_hu (coalesce to '', not EN) so the field recheck stays a strict
subset of the GIN vector (the S2 invariant). genres_col type_coerces the coalesce
to JSONB so the GIN `.contains` survives.
- browse.py: `lang` param on /library, /facets, /item, /show (validated to en|hu).
unified_library title/vector/rank/field-scope + meta filters are language-aware
for both the movie and show branches; facets unnest the active-language genre
vocabulary (jsonb_typeof guard kept); detail endpoints serve HU title/summary/
genres/show_title with EN fallback. Episodes stay EN (not overlay-localized).
IMDb-only rating (folded-in S5b review #5):
- detail.py rich_detail: drop the audienceRating/rating fallback → imdb_rating is
NULL when there's no imdb:// Rating entry (stop mislabelling a Plex audience score
as IMDb). item_detail now also serves the `rating` column (audience score;
show_detail already did) so the UI can show it when there's no IMDb score.
Tests: test_plex_lang.py (HU title serving + EN fallback, language-specific facet
vocabulary, genre-filter language matching, item_detail lang + rating split);
test_plex_detail updated for IMDb-only. DB-lane suite 293 passed / 2 skipped; ruff clean.
Persist the info-page rich fields that were previously read LIVE from plex.metadata() on every view —
imdb_rating (IMDb-specific, vs `rating`=audienceRating), imdb_id, tagline, and full_cast
([{name,role,thumb}]) — onto plex_items/plex_shows, and serve the detail endpoints from the row.
- migration 0065: ADD imdb_rating/imdb_id/tagline/full_cast (nullable → no rewrite/lock, unlike 0064);
NULL people_enriched_at on movie/show rows so the existing cast backfill re-fetches each once and
fills the new columns.
- new app/plex/detail.py: rich_detail(meta) (moved out of browse._rich_meta so sync + serve share one
parser) + apply_rich_detail(row, meta); wired into _enrich_people_batch and the info-page lazy fill.
- item_detail: movies serve cast/IMDb/tagline/genres from the row and keep plex.metadata(markers=True)
ONLY for markers + audio/subtitle streams (so detail survives a live-Plex outage); episodes (never
enriched) still parse detail from that live meta.
- show_detail: serves cast/IMDb from the row; `related` stays live best-effort and also lazily fills a
not-yet-enriched show.
- tests: rich_detail/apply_rich_detail parsing + persistence, backfill stamping, item_detail
outage-resilience + lazy fill + episode-live, show_detail row serving. Full suite 285 pass / 2 skip;
migration verified reversible (up→down→up).
Precondition for S6's pure-DB language-aware serving.
