1. (correctness) Show hero rating regression: PlexBrowse's show hero rendered a
rating only when show.imdb_rating was set, so after the S6 IMDb-only change a
show with no imdb:// entry showed no rating. Now falls back to the audience
`rating` like PlexInfo.
2. (correctness) ratingMin column mismatch: the rating filter and the /facets
rating_max now key off coalesce(imdb_rating, rating) — the SAME "best score"
the badge displays — so a ratingMin picked from a shown IMDb score narrows the
right column instead of the raw audience `rating`.
3. (altitude) HU search gap: new query.vector_match() matches EITHER vector in HU
(or_(search_vector_hu, search_vector)) so a row with no HU twin stays findable
by its English title; ranking still uses the HU vector. field_recheck unions
the HU+EN per-field tsvectors in HU, staying a strict subset of the prefilter.
4. (test-coverage) Extracted the badge logic to lib/plexRating.pickRatingBadge
(shared by PlexInfo + the show hero) with a unit test (imdb-preferred, audience
fallback, 0-score, none). Backend tests added for the HU union search + the
IMDb-preferred rating filter.
5. (efficiency) Language switch no longer double-fetches the grid: browseQ is
gated on a committedLang state that lags `lang` by one render, so the
genre-clear effect settles into a single fetch instead of one throwaway fetch
with stale-language genres plus a second.
DB-lane suite 295 passed / 2 skip; FE tsc/knip/lint clean, 217 vitest pass.
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.
