- adapters: overviewLanguages() limits overview/tagline chain to Chinese
variants (zh-CN→zh-SG→zh-TW→zh-HK); titles keep full chain; season
supplement fetch skips languages useless for overview
- setting metadata.overviewNonChineseFallback (default off) + UI switch
- media detail shows "暂无简介" for empty entity/episode overview
- scripts/overview-recompute.ts: recompute stored non-Chinese overviews
from kv_cache only (no TMDB requests), dry-run by default, --apply
- tests: chain unit tests, Heart Signal (103147) fixture, server
recompute test, MP differential for episode overview
- runbook + CHANGELOG

- metadata.includeSpecials (default true): full refresh and the language
backfill fetch TMDB season 0 (specials) when present, like MP; season 0
stays out of the episode-total ledger
- refreshMetadata promotes provisional season/episode units that match the
TMDB season/episode layout to confirmed (source=tmdb), keeping ids and all
references; non-matching units stay provisional
- content_unit.source (migration 0053): release / file / tmdb / user
- duplicate units (same entity/kind/season/episode/content type/segment) are
merged as a refresh step and via `scripts/identity-cleanup.ts
--merge-duplicates` (dry-run by default); keeper = most referenced, then
confirmed, then earliest; references auto-discovered via FKs and repointed
- ensureUnits takes a per-unit advisory xact lock to stop concurrent lazy
creation from producing duplicates
- runbooks updated; user DB read-only dry-run: 征途 S01E09/E10 4 units each
-> 1 each (6 removed), not applied

Entities created from TMDB candidates (subscription, search/TMDB preview, organize wizard)
and manual assignment to an unregistered TMDB identity take title/overview from the
metadata.languages chain at creation and enqueue refreshMetadata full=1.
