Full-epic /deep-review (11 finders + 12 adversarial verifiers) surfaced no HIGH; every
mechanism finding calibrated to LOW on verification. Fix all 13:
Correctness / reliability:
- Combobox: Enter now commits the VISUALLY highlighted row (highlightIndex ?? activeIndex),
not the bare keyboard activeIndex — so arrow-then-hover-then-Enter no longer toggles a
different option than the one painted, and hover-with-no-arrow is no longer a silent no-op.
- parse_person: dedup the known_for pool by (id, media_type), not the bare id — TMDB movie
and tv id spaces are independent, so a same-id movie+show pair is two distinct credits
(matches the collision-safe key the rest of the module already uses).
- person-enrich: a per-person in-flight + 60s cooldown guard (people._should_schedule_enrich)
dedups concurrent opens and rate-limits re-triggering while TMDB is degraded (a transient
TmdbError leaves the watermark NULL), so bursts can't pile 8s tasks onto the shared threadpool.
- PlexInfo compact()/money(): format with i18n.language (keeping currency USD) instead of a
hardcoded en/en-US, matching the app's Intl convention.
- delete the dead `plex.filter.add` i18n key (both locales) — the +Add button that used it is gone.
Reuse:
- _continue_watching reuses rollup.agg_subquery(include_resumed=True) + query.apply_show_state_filter
instead of a third hand-inlined copy of the per-show rollup + in_progress predicate, so the
Discover rail can't drift from the grid's definition.
Test coverage (the gaps a regression would ship through):
- resolve_library_guids scope-exclusion (a credit in a non-scoped/disabled library is dropped)
+ the []-vs-None distinction; parse_person cross-media-id retention; enrich_person transient
(NULL watermark) and 404 (stamp) branches; _enrich_person_bg body (fresh session close/rollback,
None-guard) + the cooldown dedup; continue_watching fully-watched-show exclusion; Combobox
Enter-commits-highlighted + async/controlled-query mode; PopoverItem aria-checked contract;
RatingsRow missing-IMDb + imdb==audience branches.
Backend lane 413→420, FE vitest 351→357; all gates green. No migration.
