1. // tmdbsync.hl — THE TMDB SYNC (tracker.worldapi.org#9): for every show SOMEONE follows, fetch the show's
2. // details, seasons and episodes from TMDB and bring storage/mpackdb/ up to date, plus the show's poster.
3. // Used by BOTH runners: the daily run inside the app (project.hl `syncTick`, one show per step) and the
4. // command-line tool (tools/sync-tmdb.hl). Reference for the API use: the old tracker's
5. // crates/sync/commands/sync.js (read-only).
6. //
7. // GET <TMDB_BASE_URL>/tv/<tmdbId>?append_to_response=external_ids the details (status, counts,
8. // overview, poster_path, seasons[])
9. // + external_ids (imdb_id, tvdb_id)
10. // GET <TMDB_BASE_URL>/tv/<tmdbId>?append_to_response=season/1,season/2… up to 20 seasons with their
11. // episodes in ONE request
12. // GET <TMDB_IMAGE_URL>/w342<poster_path> the poster → storage/mpackdb/posters/
13. // Authorization: Bearer $TMDB_READ_TOKEN
14. // GET <TVMAZE_BASE_URL>/lookup/shows?imdb=tt… (else ?thetvdb=<id>) the TVmaze id, ONLY when the show
15. // has none (301 → /shows/<id>, 404 = unknown)
16. // GET <TVMAZE_BASE_URL>/shows/<tvmzId>/episodes a SERIES' episodes on TVmaze (#15), see below
17. // A MOVIE (`type = 'movie'`, 7814 of the migrated rows, 1 followed): only
18. // GET <TMDB_BASE_URL>/movie/<tmdbId>?append_to_response=external_ids its imdb id + poster; no seasons,
19. // status, overview (it is no TV show)
20. //
21. // EXTERNAL IDS (tracker.worldapi.org#12, the show page's link icons): a MISSING imdbId/tvdbId is filled from TMDB's
22. // external_ids, a missing tvmzId from TVmaze's lookup — an id the show already has is NEVER overwritten.
23. // RULES (ticket): new seasons/episodes are ADDED, existing ones UPDATED (title, summary, release) —
24. // matched by tmdbId, never duplicated; NOTHING is deleted. An episode without a tmdbId (161 migrated ones)
25. // is matched by its S/E number instead and gets the tmdbId. A season (no tmdbId in the migrated data) is
26. // matched by (show, seasonNumber). A TMDB value that is empty/null never overwrites a stored one.
27. // Season 0 ("Specials") is only synced for a show that already has a season 0 (else every followed show
28. // would suddenly flood /my/unwatched with specials); a TMDB season with no episodes is not created.
29. //
30. // TVMAZE MERGE (tracker.worldapi.org#15): AFTER TMDB, a series with a tvmzId gets TVmaze's episode list (one request)
31. // and TVmaze FILLS GAPS only — matched by season/episode number: a missing episode (and its season) is ADDED, an empty
32. // title or air date of an existing one is FILLED; a value TMDB gave is never overwritten. A placeholder title
33. // ("Episode 4", "TBA") counts as empty — and TMDB's own placeholder never overwrites a real title either (else the
34. // two would flip it every day). When TMDB later lists the episode, the TMDB step adopts it by number (it has no tmdbId)
35. // and TMDB's values win. TVmaze specials (no episode number) are skipped, season 0 only if the show has one. SAFETY:
36. // when the two number a show differently (fewer than 80 % of the episodes both know air within a day of each other or
37. // share the title — `numberingAgrees`), TVmaze is ignored for that show (`tvmazeSkipped`). Summaries are not taken
38. // (TVmaze's are HTML; the ticket asks for episodes, air dates, titles).
39. //
40. // ADULT FLAG (mission 054): every details answer carries TMDB's `adult` — the sync, the import (search.hl) and the
41. // BACKFILL below store it as show.adult (true/false; null = not known yet, hidden from the public lists, shows.hl
42. // isPublicTitle). THE BACKFILL (`backfillTitle`, run one title per step by project.hl `backfillTick`, like the daily sync):
43. // GET <TMDB_BASE_URL>/movie|tv/<tmdbId>?append_to_response=external_ids ONE request: adult, poster_path, imdb/tvdb id
44. // GET <TMDB_IMAGE_URL>/w342<poster_path> the poster when its file is missing
45. // for every title whose adult flag is unknown (no TVmaze, no seasons — the daily sync does those for followed shows). A
46. // title TMDB answers 404 for (or one without tmdbId) gets `adultCheck` = why, stays unknown (hidden) and is not asked again.
47. //
48. // IDS ARE SELF-ASSIGNED (randomBytes, like watches.hl): hl:mpackdb's own generated @id can repeat within
49. // one millisecond, which is what made update() lose rows (hybriel#113, fixed upstream, not in the vendored
50. // build) — a table holding only unique ids is safe to update().
51. //
52. // ONE PROCESS PER STORAGE: hl:mpackdb does not coordinate two processes (hybriel#21) — the in-app run uses
53. // the app's own open tables (imported from shows.hl); the tool only ever runs against a stopped app or a copy.
54. //
