Filtered /scenes (tag/origin/q/studio/performer) ran exhaustive COUNT with
stub-filter EXISTS over 1.7M rows: TAG 5.1s, ORIGIN 4.9s, SEARCH 3.1s.
Mobile relied on `loaded < total` for infinite-scroll, making exact count
mandatory and ruling out approximate shortcuts.
Backend:
- SceneListOut gains has_more (bool) and total_capped (bool), both optional
for backward compat with old mobile
- Filtered count uses LIMIT _COUNT_CAP+1 (1000) subquery — cost is
O(min(matches, cap)) instead of O(all). Measured: TAG 5.1s→664ms,
SEARCH 3.1s→138ms, ORIGIN 4.9s→1.07s (also fixes SiteScenes showing
global count ~1M instead of per-site count)
- has_more from fetching per_page+1 rows (essentially free); extra row
stripped before serialisation
- Pure-default list (no filters at all) keeps TTL-cached full count
Mobile:
- getNextPageParam uses has_more ?? fallback to loaded<total
- Display shows "{total}+" when total_capped=true (5 screens)
Verified on emulator: tag "Big Tits" → "1000 scenes" loaded, no 500s,
backward compat confirmed (old APK works against new backend).

Counts for /tags, /performers, /studios and /favorites were computed live
per-request by aggregating scene_tags / scene_performers with an EXISTS to
playback_sources. As the catalog grew to ~1.7M scenes (6.3M scene_tags) this
ran ~4.3s for /tags?order=popular (x2 incl. the total count) and ~950ms for
the default /scenes count, making those screens load in several seconds.
- migration 0019: add scene_count (+ DESC index) to tags/performers/studios
- background job _job_refresh_taxonomy_counts (every 3h) recomputes the counts
in one UPDATE..FROM each (IS DISTINCT FROM to skip unchanged rows)
- /tags, /performers, /studios scenes path now read the column + ORDER BY the
indexed scene_count; for_movies paths keep live aggregation (small tables)
- favorites read denormalized scene_count instead of a grouped EXISTS aggregate
- /scenes default count: 10-min in-process TTL cache (header is approximate)
Measured: /tags?order=popular&per_page=500 ~8s -> 66ms incl. serialization.

Dotąd nie dało się docelować sceny konkretnego hostera — search faworyzuje
xnxx/xvideos (dominują bazę), brak filtra po źródle. Diagnostyka per-hoster
(test cookie-fix, luluvid, porntrex) wymagała trafienia sceny danego tube'a.
- /scenes?origin=<substr> — exists() na PlaybackSource.origin ilike, np.
'hqporner' łapie tube:hqpornercom
- ScenesFilterModal: sekcja "Source / hoster" (TextInput) w FilterState.origin
- ScenesScreen: filter.origin → listScenes; liczone do activeCount
