perf: root-cause fixes for endpoints still slow after #292 (NextUp, series badges, resume tail, subtitle fonts) (#350)
* docs(plans): root-cause analysis for endpoints still slow after PR #292 Five endpoint groups stayed slow after the home/Continue Watching/Latest latency work shipped: Resume (110s p95), NextUp (17s p95), Latest (17s), /Items, and the home sections routes. The caps and caches from PR #292 are live in the deployed binary; they bounded how many rows the loops touch but not what each underlying query costs. Documents the four confirmed root causes (4.3M stale completed-with-position progress rows + missing resume index, unbounded next-up anchor scan, per-episode series rollup fanout, two index-starved history/scanner paths) with live EXPLAIN ANALYZE measurements and the fix plan implemented by the follow-up commits. AI-use disclosure: analysis and doc produced with AI (Claude) assistance. * perf(catalog): bound the global next-up anchor scan to recent completions The completed_episodes CTE in buildListNextUpQuery derived per-series anchors from the profile's ENTIRE completed history — DISTINCT ON over 233k rows joined to episodes for the worst bulk-import profile, then a per-series LATERAL that scans every episode of a fully-watched series before yielding nothing. 648 slow executions in a 19h window, 44.7s worst; this drove /Shows/NextUp (17.1s p95) and the next-up injection on the native home sections aggregate. Global queries now derive anchors from the profile's nextUpAnchorMaxRows (500) most recent completed rows — an ordered index walk on idx_uwp_profile_completed, with the hidden-items exclusion and date cutoff applied inside the bounded scan so hidden/old rows never consume the anchor budget. A next-up rail surfaces ~24 series; the 500 most recent completions cover every series that can realistically rank on it. Series-scoped calls (the show-detail tile) keep the unbounded shape: they must anchor on the series' last completed episode no matter how long ago it was watched, and are naturally bounded by one series. Measured on the live worst-case profile with the exact generated SQL: 44.7s worst / ~2.6s avg before; 10ms after (together with the one-time stale-resume-point data repair applied directly to the deployment DB — see docs/superpowers/plans/2026-07-06-slow-endpoint-root-causes.md). AI-use disclosure: implemented with AI (Claude) assistance. * perf(jellycompat,userstore): aggregate series watch-state rollup in SQL The series Played/UnplayedItemCount badge on list rails (per-library Latest, library browse, search results) and series detail pages was computed by materializing EVERY episode of every series on the page (episodeRepo.ListBySeriesIDs) and then batching per-episode progress+history lookups in 500-id chunks. A 50-series page of an episode-heavy library (Sports) expanded to 32,467 episode rows and ~65 sequential queries — measured 17-18s per /Items/Latest request, and PR #292's cached Latest fast path pays it on every response for series libraries. The same fanout made /Items?searchTerm=... slow whenever the result set was mostly series (Meilisearch itself answers in milliseconds). New optional store capability userstore.SeriesEpisodeRollupStore, implemented by PostgresUserStore as one GROUP BY e.series_id aggregate with semantics identical to the chunked path (episode availability via episode_libraries, hidden-items visibility on progress rows, completed-history fold, in-progress = not watched with position > 0 — verified value-for-value against the old semantics on a real 1,586-episode series). enrichSeriesListUserData and enrichDetailUserData use it when present; SQLite-backed stores and rollup query failures keep the existing chunked path as fallback. catalog.SeasonUserDataFromCounts pins the counts-to-DTO mapping to EpisodeRollupUserData. Measured on the live worst-case profile against the real 50-series Sports Latest page: ~17s of chunked round-trips before, 119ms in one query after. Part of docs/superpowers/plans/2026-07-06-slow-endpoint-root-causes.md. AI-use disclosure: implemented with AI (Claude) assistance. * perf(catalog): bound superseded-episode completed walk to recent history The Resume / Continue Watching superseded-episode filter loaded a profile's *entire* completed history into memory on every request that contained an in-progress episode: CompletedProgressSnapshots paged user_watch_progress WHERE completed=TRUE with no upper bound. The 2026-07-06 slow-query comparison showed this surviving as a 60-116s Resume tail even after the in-progress index landed live, because the 4.3M zeroed Plex-import rows are still completed=TRUE and were re-walked every load. A completed episode can only supersede an in-progress one it was finished more recently than (the query gates on done_progress.updated_at > ip_progress.updated_at), so only completed rows newer than the oldest in-progress entry can matter. Compute that cutoff in SupersededEpisodeProgressIDs and pass it to CompletedProgressSnapshots, which — since the completed listing is ordered updated_at DESC — stops paging as soon as it crosses the cutoff. Import-heavy profiles whose back-catalogue predates their current in-progress items now stop on the first page instead of paging hundreds of thousands of irrelevant rows. Correctness is unchanged: no relevant superseding row is excluded. * perf(catalog): hard-cap superseded-episode completed walk at 5 pages The updated_at cutoff added in the previous commit bounds the completed walk on the relevance axis, but a very old in-progress entry sitting behind a large volume of newer completions could still page deep. Add a 5-page (2,500-row) hard backstop on top of the cutoff: normal profiles still stop on page one via the cutoff, and only the adversarial tail hits the cap. When it engages the tail of the completed set goes unscanned, so a superseded episode could momentarily survive on Continue Watching — we log a warning when that happens (with profile_id + rows scanned) rather than mis-filter silently, and it self-corrects once the stale in-progress entry ages out of the scanned window. * perf(playback): extract subtitle fonts in a single ffmpeg pass Embedded ASS/SSA font extraction spawned one ffmpeg process per font attachment, each re-opening the (usually CephFS-backed) media file. Anime releases carry 15-47 fonts, so the per-spawn file-open cost dominated and pushed GET /api/v1/stream/{sid}/subtitles/{track}/fonts to a 17-60 s plateau (p95 ~33 s in the live logs). Collapse the N spawns into one ffmpeg invocation that dumps every attachment to a temp dir (-dump_attachment:idx path ... -i file -map 0:t? -c copy), then read the files back. The file is opened once instead of N times, taking p95 from ~30 s to ~1-2 s with no change to output. Safety is preserved. The 32-attachment / 32 MiB caps still apply: attachment size is stat'd before read so an over-limit font never enters memory, and a watchdog polls the dump dir and kills ffmpeg if its on-disk output crosses the cap -- restoring the hard bound the old pipe-per-attachment reader enforced by killing at maxBytes+1, so a container with oversized "font" attachments can't fill the disk. Part of the slow-endpoint follow-up; see slow-query-analysis/subtitle-fonts-extraction-findings.md. * fix(review): report enforced font-byte cap; correct doc subtitle scope Address PR #350 review: - dumpFontAttachments reported the maxSubtitleFontBytes package constant in both over-limit errors instead of the maxBytes argument the caller passed, so the message misstated the enforced bound whenever a different cap was in effect (as the tests use). Interpolate maxBytes in both messages. - The root-cause plan claimed subtitle extraction was 'out of scope' while the branch actually optimizes /subtitles/{track}/fonts. Scope the out-of-scope note to subtitle *track* conversion and record the fonts single-pass work as deliverable 5. |

feat(collections): add profile-scoped display filters (#191)
* feat(collections): add profile-scoped display filters
* refactor(collections): dedup display-filter helpers per review
Address code-review feedback on the profile-scoped display filters
without changing behavior:
- Widen CompletedHistoryItemMap to accept ProgressCompletionStore and
drop the duplicate completedHistoryItemMapForProgress copy.
- Extract the duplicated MDBList candidate retry loop into a generic
collectionutil.FetchMDBListWithFallback helper, used by both the user
and library collection syncers, and cover it with unit tests.
- Reuse validateOptionalLibraryIDs in HandleUpdateCollection instead of
an inline positive-ID loop.
- Import the shared COLLECTION_{WATCH,MEDIA}_FILTER_OPTIONS in the
template config form rather than redefining them locally.

* fix(collections): sanitize query_definition library_ids fallback
readSourceConfigLibraryIDs validated source_config.library_ids (finite,
positive, truncated, deduplicated) but returned the query_definition
fallback raw, so legacy rows could surface zero/negative/duplicate IDs
that the backend now rejects on save. Extract a shared sanitizer and
apply it to both paths.
