peter 71d7646bf1 fix(plex): a name this session cannot write fails at once, and the layout has one spelling
Round 6 turned `artifact_may_arrive` into a positive rule, but keyed it to the HLS vocabulary in
general rather than to what THIS session produces: the playlist regex accepted master/index/stream_*
for every session and the `seq == 0` branch accepted any variant token unconditionally. The two argv
branches are disjoint — a single-audio session is given `seg_%d.ts` + `index.m3u8` and no `%v` at
all, so `master.m3u8`, `stream_*.m3u8` and every `seg_<variant>_<n>.ts` are names it can never write,
and vice versa — so each of those was read as "an HLS name, so wait and see" and held a threadpool
worker, plus its pooled DB connection, for the full timeout. That is verbatim the round-5 outage the
route's own comment claims it prevents.

Measured through the real route against a live single-audio session, before: master.m3u8 404 after
30.0s, stream_q7z.m3u8 404 after 30.0s, seg_a0_0.ts / seg_zzzz_0.ts / seg_0_0.ts 404 after 20.1s
each. After, on the running localdev API: 404 in 44-316ms for all of them, while index.m3u8,
seg_0.ts and seg_1.ts still answer 200 — nothing is over-refused.

The session now carries the rendition names its ffmpeg was told to write, and `entry` is derived from
them instead of passed. And "one place" now means the argv BUILDS its patterns from the same
functions the parser reads back (`segment_name("%d", "%v")`, `variant_playlist_name("%v")`): the
layout was still spelled out independently in six places, with `_VIDEO_VARIANT` read by no consumer,
which is the drift that caused round 6's HIGH. A test asserts the argv's own patterns are what those
functions produce, and that every name they expand to is one the guard accepts.

The load-bearing MEASURED comment cited ffmpeg 8.1.1 — the Windows host's. The binary that writes
these files is the API container's 7.1.5; re-measured there, the conclusion holds.

peter 7f17b17c13 fix(plex): an HLS session's file names are one vocabulary, and a name it cannot produce fails at once
Round 5 added a guard so a request for a segment beyond the produced region
answers instead of polling out the full timeout — the route is a SYNC one, so
every such wait parks a threadpool worker and, through `current_user`, a pooled
DB connection. Measured against real ffmpeg, the guard could not fire where it
mattered.

`-hls_segment_filename seg_%v_%d.ts` substitutes the VARIANT first: a dual-audio
session writes seg_0_0.ts (video) and seg_a0_0.ts / seg_a1_0.ts (the `name:aN`
renditions). The regex read those as sequence-first, so every video segment
parsed as segment 0 and every audio segment did not parse at all — the guard was
inert on every multi-audio item, which is most of this library. `_seg()` carried
the same inversion: the warm-up waited 8 s for `seg_1_0.ts`, a name ffmpeg never
writes, on every multi-audio session start AND every seek-restart.

The layout is now one constant plus one parser (`segment_name` /
`_SEG_NAME_RE`), with a test pinning them to each other, instead of three
comments that could drift — and they had drifted, all three ways.

The guard is also a positive rule now. It was a blocklist, so anything that was
not a single-audio segment name was waved through: `GET …/anything.m3u8` still
parked a worker for 30 s, while the route's comment claimed a flood of hopeless
names was what it prevented. A session produces its playlists and its segments
and nothing else. `.vtt` leaves `_HLS_CT` with it — ffmpeg runs with `-sn` and
subtitles are a separate route, so that extension could only ever name a file
that will not arrive.

Also here:
- A 5000-digit segment index reached the client as a 500: `int()` on an
  unbounded digit run raises past 4300 digits and only OSError was caught. The
  name is bounded on the route and the index in the regex — the same bug class
  the subtitle routes were bounded for.
- A session torn down between the wait and the read is a 404, not a 500. `_kill`
  rmtrees the directory and no lock spans those two steps; the player's recovery
  is keyed on the STATUS, so a 500 skipped the reclaim and ended playback with
  "couldn't play" instead of restarting at the playhead. The trigger is ordinary
  — `loadSession` awaits the new session before destroying the old hls instance.
- Two comments claimed an open player checkpoints every 10 s "whether or not it
  is playing", which is the stated reason the 30 s finished-idle reap is safe.
  `flush` sends nothing once the finish latch is up, or before a position is
  known. The states it does cover — playing or paused mid-item — are the ones
  the rule needs; the comments now say that instead of more.
- The route's tests leave the DB lane: the route reads nothing from the database
  since the auto-start was removed, and there those four regressions SKIP on a
  machine with no Postgres while pytest prints green.

14 tests, mutation-checked: the old parse, the old warm-up name, the blocklist,
both bounds off the absurd name, the unguarded read, and the route dropping
`proc` — each red on the test that names it.

peter 1f81684b6e fix(ui,plex): a dialog keeps the focus its child asked for, and a hopeless segment fails at once
Both found by UAT in a real browser, after the tests for them were already green — which is the
whole reason this repo settles focus and timing claims by running them.

- **The autoFocus fix worked, and then the dialog took the focus back.** React 18's StrictMode runs
  every effect mount→cleanup→mount in development: the cleanup handed focus back to the trigger, and
  the second mount, finding the focus outside the dialog, moved it to the first focusable — off the
  `autoFocus` field a beat after the browser had put it there. Chrome measured it: INPUT (commitMount)
  → BODY (cleanup) → ✕ (re-mount). The effect is idempotent now — it remembers what the dialog was
  focused on and restores THAT on a re-mount — and the close-time restore is conditional on the
  dialog still holding the focus, which it tracks as it changes rather than computing at cleanup,
  where the panel is already out of the document. A dialog no longer yanks focus back from wherever
  the user has since moved it.

- **Passing ffmpeg's handle to the segment wait only shortened the FINISHED case.** Measured against
  the running localdev API: a request for `seg_99999.ts` on a live session still took 20 195 ms,
  because that ffmpeg has not exited and the wait has no other reason to stop. ffmpeg writes segments
  in order, so a segment whose predecessor does not exist is not the next one and cannot arrive —
  and that is knowable at once. Same request now: 45 ms.

Verified on localdev against the real library (Westworld S01E06, remux, multi-audio): Mod+K opens the
command palette with the focus in its search field and typing reaches it; playback runs on the new
session-scoped HLS URL; a request naming a stale session id is a 404; and a viewer paused for longer
than the finished-session rule keeps their 2.4 GB session across two reaper passes — the progress
checkpoint touches it — and resumes cleanly.

peter 47af4d5c05 fix(plex): an HLS artifact names the session it belongs to, and a paused viewer says so
Deep-review round 5, over round 4's own fixes.

- Sessions are keyed by rating_key alone while a session's DIRECTORY is per (key, offset, tag), and
  the artifact URL carried no session identity — so once a seek-restart or a second viewer of the
  same item took the registry slot, the old viewer's request for `seg_12.ts` was answered 200 with
  the new session's twelfth segment: bytes from a different `-ss` offset under `-copyts`, on a
  timeline the client is not on. Wrong content with a success status is the one failure a player
  cannot notice, and round 4's reclaim-on-404 could never fire on it. The id is in the path now (so
  the playlist's relative names resolve back into the same session), a mismatch is a 404, and the
  player reclaims at the playhead. The entry playlist's auto-start is gone with it: it could only
  ever begin at 0, silently discarding the viewer's position.

- Round 4 exempted paused viewers from the reaper by keeping EVERY finished session for the full
  ten-minute idle window — one whole segmented copy of a film per item, on the volume the download
  center shares. The signal it needed already existed: an open player checkpoints its position every
  10 s whether or not it is playing, so that route now touches the session and the periodic pass is
  back on the short rule.

- POST /session's opportunistic reap was never scoped to the key being started: it walked the whole
  registry with the 30 s finished rule, so pressing play on ANY item — even a direct-play one, the
  call ran before that early return — killed another viewer's paused session. It is gone; the
  periodic pass owns reaping.

- A segment that can never arrive no longer polls out the full 20 s: the producer's handle is passed
  to `wait_for`, so a finished ffmpeg answers at once. This is a sync route, so each such wait parked
  a threadpool worker AND a pooled DB connection, and an ordinary seek past the produced region was
  enough to do it.

- The DataError handler's re-raise branch — the half that keeps a genuine DataError a 500 — is
  pinned, so simplifying it to an unconditional 422 cannot pass in silence.

Six regression tests (two route-level, in the DB lane), each mutation-checked red on the assertion
it is named after. pytest 1124, vitest 999.

peter 31dc4184f5 fix(api): a paused viewer keeps its HLS session, a refused subtitle publish backs off, and a NUL is a 422 everywhere
Deep-review round 4, backend half.

- The periodic HLS reaper (round 3) applied the "finished and unfetched for 30 s" rule that only a
  NEW session request may apply. A remux finishes long before the film, and a paused player with a
  full buffer fetches nothing, so a one-minute pause killed the session and playback died ~30 s after
  resuming. The periodic pass is `reap_abandoned` now (the long idle limit, finished or not).
- A subtitle `publish` that could not keep its output (full / read-only cache volume) returned
  quietly, so every poll queued the window and the whole-container pass again. It reports failure
  and the pass is backed off like a failed read; a cached VTT that cannot be READ is answered
  `unavailable` (`cache_unreadable`) instead of scheduling reads that can never land.
- The subtitle routes bound `rating_key` / `sub_ord` (they become a cache file name: a 250-digit
  one was ENAMETOOLONG, which pathlib's exists() re-raises -> a 500), and the cache helpers no longer
  throw on such a name.
- One app-wide handler turns psycopg's "text fields cannot contain NUL" DataError into a 422: round 3
  guarded only the by-rating_key lookup, and `contains=`, `contains_group=`, reorder/bulk key lists
  and the collection search still 500'd.
- The hand-written `db.get(...) is None -> 404 "Unknown ..."` siblings use `get_or_404` with a
  `what` (channel / video / user), so the Hungarian UI no longer shows English for a gone row.

peter 4f37c41021 fix(plex): a subtitle failure about one position no longer ends the track, and windows are read ahead and never wait behind a full pass
Deep-review round 3 of bug hunt 2026-09.

- `failed` is now final only for a track that can never be text (bitmap, no item/track/file). A Plex
  hiccup or a stretch ffmpeg could not read answers `unavailable`: said, polled again every 5 s, and
  the <track> stays mounted when cues exist elsewhere (gen > 0). Re-picking the selected track asks
  the server again at once.
- Within LOOKAHEAD_S of a covered stretch's end the next window is read ahead, instead of only once
  the playhead has fallen off it (subtitles dropped out at every edge while the full pass was backed
  off or slower than a window lasts).
- Windows and full passes run on separate pools with separate in-flight caps, so a window never
  queues behind (or is refused by) minute-long full passes — the pool comment promised that and
  nothing enforced it.
- A pass that times out is TERMinated and keeps what it reached (published as partial) instead of
  being killed and discarded.
- Lapsed failure memos are swept on every write (they were only pruned when the same key was read
  again, so polling fresh keys grew the process without bound).
- `publish` no longer merges into a sidecar with no VTT behind it, or claims a region whose VTT write
  failed, or overwrites an unreadable track with one window.
- A NUL in a rating_key names no row (it was a DataError, a 500, on every Plex route) and no longer
  500s the status poll.

Tests: 16 new, each mutation-checked (18 mutations, all red on the test that names them).

peter 473d9f02f2 fix(plex): subtitle windows land where the full pass does, and the extractor stops re-reading, respawning and outliving the process
Deep-review round 2 of the 2026-09 bug hunt, over the round-1 fix diff.

- A window was LATE by the distance to the keyframe its input seek landed on, and then doubled for
  good once the full pass merged in: a cue already running at the window's start came out at a
  negative time, and the webvtt muxer's default shifted the whole output so it sat at 0. Measured on
  the real Westworld S01E06 at 25:00: every window cue +5.005 s, 682 cues merged instead of 608.
  `-avoid_negative_ts disabled` keeps the times exact (the parser reads ffmpeg's signed-field
  spelling of a negative time); now 608/608 on that file, and a real-ffmpeg test pins it.
- A full pass that failed was re-armed every minute while the viewer watched what it did publish —
  a whole-container read per minute. It now backs off for an hour; windows keep running meanwhile.
- A failed WINDOW set the track's failure memo, so any uncovered position read "failed" — a final
  answer that ends the player's poll, even with the full pass about to deliver, and one any account
  could plant with an absurd `at`. It now marks only the span it failed to read; "failed" is given
  once the full pass AND a window there have both failed.
- Windows join by what they COVER, not a bucketed identity: a backward seek no longer waits behind a
  window that cannot cover it, and a playhead crossing a bucket edge no longer queues a second read.
  The queue is bounded per track and overall.
- shutdown() sets a flag a worker checks before it spawns ffmpeg (one still in its Plex lookup used to
  start a read after the kill sweep); queued-job cancellation and the lifespan call are now tested.
- A window starts where ffmpeg is told to seek (rounded to the ms it gets), a rounded-up millisecond
  carries into the minute (no more `00:00:60.000`), a key's first publish claims nothing before its
  VTT lands, and `at`/`offset`/`start`/`aoff` refuse non-finite values (`at` also an absurd one).

peter d2ba65e383 fix(plex): the subtitle poll backs off on errors, a failed <track> is replaced, and a resume asks for the right window
Deep-review R2, plus one defect found while verifying it on localdev.

- The status poll re-armed every second after a FAILED request: `data` stays empty on an error,
  so it read as "still preparing" for as long as the player was open — and the request was not
  quiet, so a persistent 500 re-opened the global error dialog every second. It now backs off to
  10 s (a blip still heals on its own) and is quiet; the player already shows the failure inline.
- A <track> whose own VTT fetch failed never fetched again: with the server's answer unchanged its
  key was unchanged, so React kept the dead element — silently blank subtitles. The key (now built
  in the hook, where it is tested) carries a failed-load count; after two remounts the track is
  reported as unavailable instead.
- Found in UAT: until the first timeupdate `abs` is 0, so after a resume every poll said at=0 and
  the first window was cut around the head of the film (a resume at 20:00 polled at=0 for as long
  as it stayed paused). The poll reports the session's start until playback ticks. And the window's
  dedup identity is the track plus a window-length bucket of its start — keyed on the track alone
  (R1), the right window queued behind that wrong one.

The poll's start/stop rules finally have tests (every earlier one resolved a single fixed answer).
Verified on localdev against Westworld S1E6 resumed at 20:00: the polls carried at=1197, one
subtitle line on screen at 21:02, the poll stopped at `ready`; the real file's window (56 cues) +
full pass (608) merged to 608 — the old merge would have served 664. 11 mutations, all red.

peter cf7ec5e9ec fix(plex): the subtitle extractor's seams — doubled cues, a truncated track cached as whole, a poll that respawned ffmpeg
Deep-review of the bug-hunt round (R1). The background extractor from ed4ab4e1 held, but its seams
did not:

- Window + full pass doubled every cue in the first hour. merge_vtt de-duplicated on the raw timing
  text, and the two passes spell a timestamp differently (shift_vtt writes HH:MM:SS.mmm, ffmpeg's
  webvtt muxer drops the hour below 1 h; shift_vtt(-0.0) never normalised the full pass). Timing is
  now parsed and re-emitted canonically, keyed with the cue text so two cues sharing a time survive.
- A full pass that exited non-zero was published as complete: "ready" forever, subtitles ending
  where ffmpeg died, and no eviction to ever retry. It now covers only up to its last cue, is never
  complete, and records the failure memo.
- The window's dedup identity held the live playhead, so every 1 s poll queued another read of the
  file. It is keyed on the track now, and a queued job re-checks coverage before reading anything.
- A sidecar track waited behind an unrelated embedded full pass (the full job is per item). Its
  window job now fetches it whole — one small request.
- The <track> fetch ran the scheduler at position 0: an unrequested window over the head of the file,
  and a refusal of a window that was on disk. It is a pure read of the cache now.
- publish() is serialised (a lost update became permanent once complete was set); the pool is shut
  down and running ffmpeg children killed at app shutdown (they held interpreter exit for minutes);
  ?at=inf is a 422, not a 500; and both subtitle routes use current_user instead of the cookie-only
  poster gate, which let a suspended or epoch-revoked session keep scheduling reads (pre-existing).

_extract_and_publish finally has tests of its own — every earlier test stubbed it out. 19 mutations,
each red on the assertion that names it.

peter 889d2acf52 feat(plex): the collection page sorts, and a linked collection has a name
Two halves of the same report ("Collectionben nem működik a rendezés?"). The pasted browse URL
sorts correctly — that part was working. What did not:

The Collection INFO page had no sort control at all and a hardcoded release-year-ascending order.
It now shows the browse grid's Sort control, with the browse grid's vocabulary, because a second
sort vocabulary on a neighbouring surface is exactly the kind of drift this repo keeps paying for:
`PLEX_SORT_KEYS` is now one tuple in `plex/query.py`, and a test pins BOTH implementations to it —
browse's key→column map (extracted from the handler to be reachable) and the collection page's
key→member map. A key added to the vocabulary without teaching one of them fails the gate instead
of putting a dead option in the menu.

Ordering a collection cannot be a single ORDER BY: its two legs are different tables, so the merged
member list is sorted in Python. Members with no value for the key sink to the END in both
directions (a movie with no rating is not "the worst rated" — the browse grid's `nullslast()`), and
ties always resolve title-ascending, so flipping the direction reverses the ranking rather than the
alphabet inside it. `lastwatched` needed the show leg's `resumed_at`, so the page now takes ONE
rollup pass that yields both the badge status and the recency instead of the status alone — without
it that menu entry would have ordered every show as never-watched. The default stays release-year
ascending: a franchise reads in release order, and that is what the page did before.

The other half: a shared Plex link carries the collection filter as bare rating_keys, so a link
opened cold had no name for them — the sidebar token rendered `17045` and the chip could only say
"Collection". `GET /api/plex/collections` takes a `keys=` CSV now, and a display-only hook resolves
just the missing ids. It deliberately does NOT write them into `collectionTitles`: that map is
hashed into the Plex query keys, so storing a resolved label there would split the cache from the
identical state and refetch the grid for a piece of text.

Verified in the browser on localdev against the real Plex library: the movie collection's menu
offers Length and the show collection's does not (the same scope rule as browse); rating-ascending
reorders 8.1/7.4/7.2/6.6/6.5 correctly; `lastwatched` on a show collection brings the in-progress
shows up; the choice survives a reload (it is a server pref, on its own key so opening a collection
never re-sorts the library behind it); and the reported URL now reads "Pirates of the Caribbean
Collection" in both the sidebar and the chip.

12 pytest + 8 vitest, mutation-checked against 14 mutations (direction ignored, nulls first, no
stable tiebreak, unknown key untouched, wrong default, show recency dropped, empty `keys=` falling
through to everything, a key missing from either sort map, every id refetched, ids unsorted,
fetched titles unmerged, the chip ignoring them, the hook's result never reaching the builder) —
each red on exactly the test that names it.

peter 5a42d76e8a feat(plex): an off-by-default loudness normalisation toggle for playback
Bug hunt 2026-09, item 14 — "how does the multichannel downmix work, and is it
normalised?" It isn't: `plex/stream.py` has always encoded `-c:a aac -ac 2 -b:a
192k`, i.e. fixed stereo with ffmpeg's default downmix matrix and no loudness
handling at all, which is why a film mastered for a cinema arrives with whispered
dialogue and deafening action.

New admin knob `plex_audio_loudnorm` (Configuration → Plex), DEFAULT OFF: it makes
a film markedly louder and narrows its dynamic range, which is a taste call rather
than a fix. It sits at the end of the Plex group, after the software-transcode
knobs — it is an audio concern, not one of the libx264 ones.

  -af aformat=channel_layouts=stereo,loudnorm=I=-16:TP=-1.5:LRA=11,aresample=48000

Three things about that chain are load-bearing and each has a test:

  * the downmix is FORCED FIRST rather than left to `-ac 2` — measuring 5.1 and
    folding it down afterwards would normalise something other than what is heard;
  * the trailing resample is not decoration: `loudnorm` runs its own resampler at
    192 kHz internally, which the AAC encoder will not take;
  * one `-af`, no stream index, so EVERY audio rendition of a multi-audio file is
    normalised — not just the first.

The knob is also part of the session directory name (`…_multi-ln_+0.00`), because
it changes the audio the segments contain, and a session left over from before the
admin flipped it must not be mistaken for one that honours it. The suffix is
appended with a DASH: `_SESSION_DIR_RE` treats the tag as one underscore-free
field, and that regex is the only thing keeping the orphan sweep off what may be a
shared scratch path. A test pins both halves — the name changes, and the sweep
still recognises it.

Measured end-to-end on the app's own HLS segments (a real 5.1 AC3 file, same item,
same 160 s offset, same ten segments): OFF -35.2 LUFS, ON -17.2 LUFS. On a 60 s
bench: I -27.6 → -16.6 LUFS with LRA 13.3 → 9.8 LU. A/V sync is untouched — under
this pipeline's own `-copyts` the audio start PTS is identical with and without the
filter, so the 3 s lookahead desyncs nothing.

Direct-played files are served untouched and stay so; a 5.1 mix is always `remux`,
so the reported case is fully covered.

peter ed4ab4e13c fix(plex): subtitles stop blocking the request, and stop re-reading the file
Bug hunt 2026-09, items 8 and 12 — the two things the Plex player was measurably
lying about.

Item 8: picking a subtitle track showed nothing for a long time, and the reported
workaround was to stop/start until it suddenly worked. Measured on prod against a
17.06 GB MKV with two embedded SubRip tracks:

  full pass, one track                154 s
  full pass, both tracks in ONE run   111 s
  -c:s copy (no WebVTT conversion)    143 s
  from 1:00:00 to the end of file      66 s
  a 630 s window at 1:00:00, both       8 s

So the conversion was never the cost: ffmpeg streams every byte of the container
between its seek point and its stop point, and the array delivers ~140 MB/s. The
only lever is reading less. Three changes follow from that:

  * a window around the playhead is extracted and published FIRST (seconds), and
    the full pass completes behind it;
  * every embedded text track rides that same single read — picking Hungarian used
    to cost a full pass and then switching to English cost another one;
  * none of it happens inside a request any more. The endpoint answers 202 while a
    background worker extracts, the player polls /status (carrying its position, so
    the window follows the viewer), and one ffmpeg run finally has a timeout.

-copyts is deliberately absent from a windowed pass: with it ffmpeg ignores -t and
reads the whole container anyway (measured — a [0, 600 s] window still took the
full 145 s), so a window comes back on a zero-based clock and is shifted to
absolute time here. Cached tracks written by older builds have no coverage sidecar
and count as complete, so nothing is re-extracted after the upgrade.

The <track> is no longer mounted before the server has something to put in it; a
"Preparing subtitles: …" notice stands in, and a track that can never be shown says
why instead of leaving the viewer to conclude the picker does nothing.

Item 12: "Bitrate" read a constant 211 kbps on every remux, because it was the
master playlist's BANDWIDTH — which ffmpeg derives from the one stream whose rate
it knows, the -b:a 192k AAC track, plus 10%. It is a measurement now: bytes per
second of MEDIA from hls.js FRAG_LOADED, accumulated per fragment type and summed
(a multi-audio session's video and audio renditions cover the same media seconds,
so pooling them would report half the truth), and an honest dash until the first
fragment lands. The panel also finally names the audio and subtitle track in play.

Verified in the browser against the real Plex library, and every new test
mutation-checked.

peter b8bff504d8 fix(plex): "Clear resume point" now tells Plex about an in-progress item
The button deletes the local row and mirrors the un-mark to Plex, but it decided whether
to push from the previous STATUS alone (prev_status != "new") — and an in-progress item's
row is status="new" carrying a position, which is exactly how the importer maps a bare
viewOffset. So for the single case the button exists for, nothing was ever sent to Plex:
the offset stayed, and the next pull imported it straight back. The user cleared Protector
twice and it returned to Continue watching at 92s both times.

Push now when Plex holds anything to clear — a view count, or a resume point. "hidden"
stays Siftlode-only and pushes nothing, which is what this endpoint's docstring always
claimed and the status-only guard contradicted.

One unscrobble clears BOTH viewCount and viewOffset — measured against the live server from
a watched+offset state and an offset-only one, so the push itself needed no change. The
client docstring that claimed "clears viewCount" is what sent the first diagnosis down a
wrong path (a timeline write with time=0, which does not clear an offset at all); it now
records what the server actually does.

Verified end to end on the real Plex server: the button leaves viewCount=None viewOffset=None,
and a full 44,885-item re-import brings back no row for it.

peter cedebe0ffb test(e24): close the review's coverage gaps, and correct a comment that was untrue
`test_only_a_show_row_pays_for_a_resolution` seeded no watch state, so every rail query
inner-joined its way to zero rows and the loop body — with it the assertion — never ran. It
now seeds a video, a movie and an episode, and asserts all three kinds are present before
the loop, so it cannot go vacuous again.

The Plex half of the surprise rail had no test for either of its promises: every test that
reached `plex_surprise` passed budget="any" against a library with no state rows, so the
duration bounds and the already-started exclusion could both be deleted with the suite
green. The YouTube half has had tests for the same two rules since S1 — the asymmetric half
of one principle.

`plex_item` and `plex_show` — two of the five pinnable kinds — were pinned by no test at
all, leaving the rating_key → internal-id translation and both shelf arms uncovered,
including the self-reference cycle that once 500'd the shelf. And `GET /api/discover/pick`
was exercised only through its domain function, so the route's own query-string translation
could regress silently; the new test excludes all three candidates, which is what proves the
whole list parsed rather than one unsplit string.

`PIN_COLUMNS`/`PIN_KINDS` claimed in a comment to be the one place the pin vocabulary is
spoken and had no readers anywhere: `resolve_ref` re-spelled the column names and the route
re-typed the kind list. Both now drive off the constants.

The `_NO_TS` sentinel was introduced as a crash fix and is not one. The key it replaced,
`(ts is not None, ts)`, cannot raise — tuple comparison finds the first UNEQUAL element via
`==`, so two null keys compare equal and `None < None` is never reached; three independent
runs confirmed it over every permutation. The rationale now says what the sentinel actually
buys, lives once in `plex.rollup`, and the third rail that was still on the older spelling
has been swept to match. Its test is renamed and re-scoped to the mutation it does catch.

Frontend: the reroll's second press asserted `expect.any(Array)`, which cannot tell an
accumulating exclusion window from a replacing one — both that and SEEN_WINDOW = 1 (each
reinstating the measured nine-card cycle) left the suite green. And `onInfo`'s jump type was
untested while `onPlay`'s was pinned twice, so pointing the ⓘ affordance at the player
typechecked and shipped green.

All eight fixes mutation-checked; every mutant died on its intended test.

peter 013f19faca refactor(plex): move content_libs down into the query layer
The browse scope is a pure DB query with no request state, but it lived in
routes/plex/_shared.py. E24's Home surface needs the same scope from a domain
package, and a domain package importing from routes/ inverts the one-way
dependency CLAUDE.md draws.

Moved to app/plex/query.py and renamed to content_libs (public — it is a domain
helper now). Swept all five call sites and both tests in one go rather than
leaving a re-export shim: the canonical-patterns table already names the
routes.admin re-export as the anti-pattern.

peter c1a3b7b935 fix(plex): gate the part-key re-probe to single-version items; drop dead i18n key; cover cross-facet narrowing
Deep-review round 2 on the round-1 fixes (all low):

- part_key churn (state): round 1's part-key reset re-probed EVERY sync for a
  multi-version item (an original + a Plex 'Optimized' copy), because
  _media_facts reads media[0]/part[0] whose order Plex doesn't guarantee stable,
  oscillating transcode_hw between the two versions. Gate the part-key signal on
  a single-version item (len(Media)<=1); codec-change reset still applies to all.
  A multi-version same-codec re-encode not self-healing is an acceptable rare
  edge; a per-sync re-probe loop is not.

- dead i18n key: this diff's playableClass() collapses to transcode_hw/sw, so the
  bare plex.playable.transcode key it orphaned is now unused (knip can't see
  dynamic keys). Dropped from both locales, parity kept.

- test: cross-facet narrowing by an active playable class (a co-facet's year
  range collapses to the selected subset) — the flip side of self-exclusion,
  previously unpinned.

The aria-label+title double-announcement on the card dot is a deliberate accepted
trade-off (reliable SR name + mouse tooltip). Backend + FE gates green.

peter bf98b48517 fix(plex): re-probe on file replace, HU parity, public class const, playback-class test gaps
Deep-review round 1 on feature/plex-playback-class-filter:

- Sticky watermark (medium): _apply_item reset the bit-depth probe watermark
  only on a codec-string change, so a same-codec re-encode (8-bit->10-bit HEVC)
  kept a stale video_bit_depth/transcode_hw forever (the backfill only re-probes
  media_probed_at IS NULL rows). Also reset when the Plex Part key changes (the
  file was replaced), not just the codec.

- i18n parity (medium): the HU playback-class labels were mixed-language (only
  'direct' translated). Translated remux/transcode_hw/transcode_sw and the
  tooltips consistently to Hungarian (Kozvetlen streameles / Atkodolas).

- Layering (low): _PLAYBACK_CLASSES was module-private yet imported across into
  routes.plex.browse; renamed to public PLAYBACK_CLASSES (it is the shared
  source of truth for facet order + zero-fill).

- a11y (low): the browse-card playback-class dot conveyed meaning only via a
  mouse-hover title; added role=img + aria-label so SR/touch users get the class.

- tests: the NULL/unprobed transcode_hw -> SW fold (filter + facet), facet
  self-exclusion under an active playable filter, the migration codec-set ==
  HW_DECODABLE_CODECS drift guard, the probe-batch bound + oldest-first order,
  the transient probe-failure retry path, and the same-codec re-encode re-probe.

Backend gate green (ruff + full pytest); FE gate green (tsc/lint/knip/prettier/
vitest). NOTE: the facet-vs-runtime disagreement for 10-bit HEVC (C1) is the
known merge-order constraint — this branch's runtime is codec-only; the facet
becomes truthful once BUG1/tonemap's bit-depth-aware routing lands with it. Left
as a sequencing constraint, not code-changed here.

peter b563155a37 docs(plex): correct the cull-yield fallback comment to name the real route 404s
Deep-review round 3: the only surviving finding — a comment-drift nit. The
fallback's cull-yield comment named the route's 'Not available yet' path, but a
culled-key segment request actually returns 'No active playback session' (the
substantive invariant — never a None that 404s as file-not-found — is unchanged).
Reworded to match the route. Concurrency + correctness came back clean.

peter 915319fa35 fix(plex): make the HW->SW fallback supersede-check atomic; honest cull yield
Deep-review round 2 on the round-1 fix:

- Race (medium): the round-1 identity guard did the supersede check and the
  respawn in TWO separate _lock sections. A newer same-key session installed in
  the gap was still torn down by _spawn's unconditional pop+kill (the round-1
  comment even had the direction backwards). Fold the check into _spawn via a
  new replace_only= param: the identity test and the pop+replace now share ONE
  lock, so the respawn is a true no-op when superseded/culled.

- Honest states (low): the superseded branch returned current_session(key),
  which is None when the key was cap-culled during our out-of-lock wait; the
  route turns None into a dishonest 'Media file not found on disk' 404 for a
  file that exists. Yield 'current_session(key) or s' so a culled session
  degrades to the route's retryable 'not available yet' path instead.

- Hygiene: _want_hw docstring corrected (it is a test-only shim now; production
  decides via _select_encode) and the two stale _want_hw references refreshed
  (stream.py header, config.py plex_transcode_hw).

- tests: the cap-cull no-respawn/no-None sub-case; the _opencl_present except
  OSError branch (glob raising, not just empty); tightened a tautological -vf
  assertion. Backend gate green (ruff + full pytest).

peter a2a8f5681d fix(plex): don't tonemap 10-bit SDR; identity-guard the HW→SW fallback
Deep-review round 1 on feature/plex-hdr-hw-tonemap:

- F1 (correctness): _select_encode gated tonemap on bit-depth alone, so a
  10-bit *SDR* (bt709) source got the HDR hable tone curve applied, visibly
  altering an SDR picture where only a 10->8-bit downconvert was needed. Split
  the ffprobe gate into a 3-way classifier (_probe_video_kind: hwsafe / hdr /
  sdr10); only true-HDR (PQ/HLG) takes the OpenCL tonemap graph, 10-bit SDR
  drops to software libx264 (an exact downconvert). Applies to both auto and on.

- F2 (race): the runtime HW->SW fallback popped+killed _sessions[key] with no
  identity check. Because wait_for blocks OUTSIDE _lock, a concurrent same-key
  _spawn (rapid seek-restart) or _enforce_cap cull could kill this session; the
  fallback then respawned software over the NEWER session and breached the
  transcode cap. Guard the respawn: only fall back if _sessions[key] is still
  this session, else yield the currently-registered one.

- tests: 3-way classifier (incl. HLG + empty-probe), real _opencl_present glob,
  real wait_for proc fast-fail branch, tonemap-variant fallback, the F1
  regressions (auto + on), the supersede/no-respawn race, and the on/opencl
  matrix cell. Backend gate green (ruff + full pytest).

peter 4827aebb7f feat(plex): HW HDR→SDR tonemap for 10-bit/HDR transcode (OpenCL on the iGPU)
Upgrade mode-3's 10-bit/HDR branch from "route to software libx264" (BUG 1's
behaviour) to a full-GPU pipeline: VAAPI decode → OpenCL tonemap (hable,
HDR10/HLG → bt709 SDR nv12) → h264_vaapi. Gen 9.5 (UHD 630) can't tonemap in
the VAAPI VPP (tonemap_vaapi fails), so OpenCL is the only HW route — proven on
the prod iGPU at ~4.2x realtime, ~1 CPU core.

- stream.py: `_select_encode` returns (hw, tonemap); a 10-bit/HDR HW-decodable
  source picks the tonemap graph when the OpenCL runtime is present, else drops
  to software. `_opencl_present` gates on a registered ICD. `_venc_opts` /
  `_hwaccel_in_opts` gain the tonemap variant (named vaapi+opencl devices,
  `-filter_hw_device ocl`, hwmap→tonemap_opencl→hwmap reverse). `_want_hw` kept
  as the hw-half wrapper. The runtime HW→SW fallback still backstops a session
  that emits no segment.
- Dockerfile: add the Intel NEO OpenCL runtime (intel-opencl-icd). It was removed
  from Debian trixie, so it's pulled from bookworm (22.43 still supports Gen 9.5;
  the .deb runs on the trixie base — verified live). Harmless without /dev/dri.
- route + FE: thread `tonemap` through the session response; the stats overlay
  mode row reads "transcode · GPU · HDR→SDR" for the tonemap path.
- tests: tonemap command branch, the (hw, tonemap) selection matrix (auto/on ×
  8-bit/10-bit × opencl), start_session tonemap wiring, and the fmtMode tag.

peter 840526b1b8 feat(plex): filter the feed by playback class (Direct Play / Direct Stream / Transcode HW/SW)
Adds a movie-scoped "Playback" filter to the Plex feed so a user can isolate items by how
they play — the groundwork for collecting HW-transcodable (or no-transcode) versions.

Four classes derived from the stored `playable` + a new `transcode_hw` facet:
- Direct Play (direct), Direct Stream (remux)
- Transcode · HW  — playable=transcode AND the iGPU can hardware-transcode it
- Transcode · SW  — playable=transcode, software libx264 only

The HW/SW split is precise, not codec-only: a 10-bit/HDR HEVC is HW-decodable yet breaks the
VAAPI nv12 pipeline (the same case plex/stream special-cases), so it must count as SW.

Backend:
- New PlexItem columns (migration 0077): transcode_hw, video_bit_depth, media_probed_at.
  Migration backfills transcode_hw codec-only so the filter works immediately.
- `plex.sync.transcode_hw_capable` is the single classifier; the HW-decodable codec set moves
  to sync as `HW_DECODABLE_CODECS` and plex.stream imports it, so the catalog facet and the
  runtime encoder choice can't disagree by codec.
- Bit-depth backfill (`_probe_media_batch`, wired into sync): probes only HW-decodable transcode
  items' video Stream for bit-depth + HDR and refines a 10-bit/HDR HEVC to software. Bounded
  per run, watermarked by media_probed_at. A codec change resets the watermark (stale probe).
- Filter + self-excluded facet on a shared `playback_class_expr` CASE (movie-leg only — a show
  is an aggregate with no single class). transcode_hw threaded onto the feed/detail/card JSON.

Frontend:
- Multi-select "Playback" Combobox in the sidebar (movie scope, facet-empty drop-out), active
  chips, 4-way corner-dot badge (green/blue/amber/red) + tooltip, and an info-page playback chip
  with a codec · bit-depth subtitle. New `bg-info` (blue) token, i18n HU/EN parity.
- Fix a regression where the card's playback dot lost its hover tooltip: the full-card reveal
  overlay swallowed the cursor; the dot now sits above it (z-20).

Gate: backend full lane + frontend typecheck/lint/knip/prettier/vitest all green. Browser-UAT'd
on localdev (filter narrows to the SW set, facet counts, badge colour + tooltip, info chip).

peter 10d69cb316 fix(plex): route 10-bit/HDR HEVC to software + runtime VAAPI→libx264 fallback
A 10-bit/HDR HEVC source (e.g. an HDR10 x265 file) died at scale_vaapi=format=nv12
on the UHD 630 (Gen 9.5 VPP: "VAProfile not supported"); ffmpeg produced 0 segments
and the item never played, with no fallback — a retry just re-picked the failing HW
path. An 8-bit HEVC and the same file on libx264 both work.

Two defenses:
- `_want_hw` auto mode now also gates on an 8-bit-SDR source via a new
  `_probe_video_hwsafe` ffprobe (bit depth from pix_fmt/bits_per_raw_sample, HDR from
  color_transfer) — a 10-bit/HDR source takes the software libx264 path, which
  downconverts to yuv420p cleanly. The Plex mirror stores no bit-depth signal, so this
  is probed at session start. "on" still trusts the admin and skips the gate.
- `start_session` adds a runtime HW→SW fallback: a HW session that emits no first
  segment respawns on libx264 and reports hw=False (the route/stats overlay honestly
  show CPU). `wait_for` gained an optional `proc` so a dead ffmpeg fails fast instead
  of burning the 25s budget before the fallback fires.

Tests: TestProbeVideoHwsafe (parsing + probe-failure-assumes-safe), the 10-bit auto
gate + "on" skip in TestWantHw, and the no-segment HW→SW respawn in
TestTranscodeStartSession. Backend lane green.

peter 00539a4d97 fix(plex): deep-review follow-ups on E6 transcode + player polish
Eight verified findings from the sprint deep-review:

- Transcode cap: _enforce_cap now counts only transcode sessions, so a
  live remux (stream-copy) stream can no longer be LRU-evicted mid-play —
  matching the config comment + the HU/EN Config hint that promise remux
  is uncapped.
- Player Back: the browser/mouse Back interceptor (BackClose) now also
  mounts for the stats overlay and up-next card, so Back closes them first
  instead of ejecting the whole player (keyboard/Esc already did).
- Honest cold-start: loadSession clears sessionIsTranscode up front, so a
  transcode->direct/remux switch no longer flashes a stale "Preparing
  stream..." during the session request.
- Stats overlay a11y: the close (X) buttons in the stats, help and info
  overlays now read as "Close"/"Bezaras" (new plex.player.close key), not
  "Back"; dropped aria-live from the per-second stat grid so a screen
  reader is not flooded with telemetry.

Tests: route-level transcode routing (transcode item -> HLS re-encode
session, remux stays copy, direct opens none); start_session threading the
preset/crf/max_height knobs + hw/preexec into the ffmpeg argv; UpNextCard
countdown auto-advance, Play-now, Cancel and the S?-E? heading fallback.

Also brings UpNextCard.tsx / plexStats.ts / plexStats.test.ts to prettier.

peter ce96032edb feat(plex): transcode resource discipline + admin knobs (E6 S1c)
The software-fallback re-encode now runs deprioritized and admin-configurable.
The SW transcode ffmpeg child is niced (preexec_fn → os.nice, applied per-child
because the Popen lives in the long-lived API process, which must NOT itself be
niced — unlike the download worker's whole-process _deprioritize) so a CPU-bound
re-encode can't starve request handling or playback; the VAAPI path needs none of
it.

New sysconfig knobs (plex group, rendered on the admin Configuration page, i18n
HU/EN): plex_transcode_hw (auto/on/off, layered onto _want_hw), plex_transcode_
preset, plex_transcode_crf, plex_transcode_max_height (software-only downscale-to
cap; the GPU path encodes at source resolution). plex_max_transcodes stays the
concurrency cap (comment corrected — the fallback is shipped, not "later").

pytest extends the command-builder + _want_hw coverage (preset/crf/max_height
plumbing, the on/off/auto policy). Browser-UAT'd: max_height=240 drops the live
resolution to 330x240; the SW ffmpeg child runs at nice 10 (ppid=api process).
2026-08-30 01:22:30 +02:00
peter 0658f9550b feat(plex): transcode playback mode — VAAPI/libx264 re-encode (E6 S1b)
Non-h264 items (playable="transcode": HEVC/VP9/AV1/MPEG-2/XviD…) now play by
re-encoding the video to H.264 inside the existing HLS session, instead of the
old HTTP 501. VAAPI hardware encode (h264_vaapi, full GPU decode→scale→encode
pipeline) where the render node is present and the source is HW-decodable;
libx264 software fallback otherwise (yuv420p 8-bit, -threads reserve-one-core).

The re-encode mints a keyframe at every segment boundary (-force_key_frames) so
the HLS muxer still cuts independent segments and seeking works; everything else
— -copyts, the HLS tail, multi-audio renditions, the AAC audio path — is the
same machinery as remux, so hls.js/subtitles/seeking are unchanged. The session
route returns transcode/hw so the player can surface the active mode.

pytest pins both command branches (software + VAAPI shape) and the HW-selection
gate (render node present AND source HW-decodable). Browser-UAT'd on the XviD
fixture (Winning London): 501→plays, real 528×384 H.264 frames, 0 dropped, seek
lands clean; stats overlay Mode row reads "transcode".

peter 257dc5741d fix(plex): resolve movies stuck "in progress" on the 15-min incremental sync
The incremental watch-sync (run_plex_watch_sync) learned a movie's watched
transition only from the history feed + onDeck. When a movie is finished on
Plex (commonly by scrubbing through the end credits) Plex sets viewCount>0,
clears viewOffset and DROPS it from Continue-Watching, so onDeck no longer
lists it (and onDeck can only ever ADD an in-progress row, never resolve one),
while a scrub-to-end frequently emits no history session row. The stale local
status='new', position>0 row then survived until the DAILY full reconcile —
which is why movies kept showing "in progress".

Add _reconcile_inprogress_movies: for each local in-progress MOVIE that Plex's
onDeck no longer lists, read its current per-account viewCount/viewOffset with
one metadata() call and apply it via the shared _pull_apply, flipping to
watched when Plex says so. Bounded by a probe cap (100), most-recently-touched
first; episodes are left to onDeck/history. No-signal rows are preserved (an
un-watch stays the daily reconcile's job).

Tests: watched-flip, onDeck+episode skip, and no-signal-preserved.

peter f80ed115ad fix(plex,channels): deep-review fixes — durable watch-sync + no shared-link clobber
Deep-review of the quickfix batch surfaced two data/preference-loss bugs plus
smaller items; all fixed with tests.

- watch_sync _pull_apply: don't let the Plex-authoritative pull overwrite a DIRTY
  local row (a change whose immediate push failed) — that stranded the value
  forever since _repush_dirty only retries dirty rows. Leave it dirty for re-push.
- PlexProvider / ChannelsProvider: a partial shared link opened in a fresh tab
  persisted mount-time DEFAULTS over the account's stored scope/sort/filters
  (base read before the account was pinned). Persist/keep only URL-present dims;
  re-hydrate the omitted ones from storage.
- playback resume write-back: guard against out-of-order delivery (a superseded
  older push now drops) and evict the throttle map so it can't grow unbounded.
- PlexPlayer: announce mid-playback buffering to assistive tech (role=status +
  sr-only label); new plex.player.buffering (HU+EN).
- columnSort: hoist the shared key:dir sort codec used by both URL-state modules.
- Tests: dirty-guard + flag-settle + per-key throttle scoping + superseded-push
  (backend); hold-repeat/suppress-click/unmount + partial-link no-clobber +
  refetch-doesn't-clobber-undo (frontend). Backend pytest 475, FE vitest 519.

peter 8299ea72b7 feat(plex): 'last watched' browse sort + auto-apply in the in-progress view (S3)
Add a 'lastwatched' sort key to the unified Plex browse. Movies rank by
coalesce(progress_updated_at, watched_at); shows by max(coalesce(...)) across
their episodes (rollup.resumed_at, now broadened from progress-only so watched
episodes count too). Never-watched titles sink via nullslast.

Frontend auto-applies lastwatched:desc when entering the in-progress watch-state
view and restores the pre-entry sort on exit; a manual sort change while there
still wins. i18n HU+EN. Backend tests cover both union legs + mixed nullslast.

peter 3f8257059d feat(plex): Plex-authoritative watch-sync — resume write-back + faster pull (S2)
Make Plex the source of truth for watch state:

- Write-back during playback: item_progress now pushes the resume position to
  Plex on the periodic checkpoint too (not only the final flush), throttled to
  one push per item every ~10s (in-memory, single-process rate limiter). The FE
  now also fires an immediate (debounced) push on seek.
- Faster incremental pull: 30 → 15 min (plex_watch_sync_interval_min).
- Plex-authoritative pull: _pull_apply resolves a genuine divergence to Plex's
  state instead of last-write-wins; the _same_state + synced_to_plex short-circuit
  still prevents a freshly-pushed row from bouncing. Removed the now-unused
  _LWW_TOLERANCE_S / _sift_ts.

Tests: 5 new in test_plex_watch_sync.py (Plex-wins resume/watched, no-bounce,
throttle final vs periodic).

peter 12d9561ba1 fix(plex): warm up HLS buffer on session start + player loading/buffering spinner
The Plex player stalled ~2s a few seconds into every auto-advanced next
episode. Root cause: each auto-advance spins up a cold ffmpeg HLS remux
session, and for a fresh start (start_s==0) start_session returned
immediately with zero buffer — hls.js drained the first segment, then
rebuffered waiting for the still-warming ffmpeg to write the next one.
Once ffmpeg gets ahead (stream-copy is faster than realtime) it never
stalls again.

- stream.py: before reporting a session ready, wait for the first
  _WARMUP_SEGMENTS (3) video segments to exist — the seg0 wait is now
  unconditional (was start_s>0 only) and warm-up runs for all starts.
  Best-effort and bounded: stop at the first segment not ready in time.
- PlexPlayer.tsx: a loading/buffering spinner. The existing overlay only
  covered the INITIAL load (!ready); add a `buffering` state driven by the
  video's waiting/stalled/seeking (set) and playing/canplay/seeked/pause
  (clear) events so a mid-playback stall or in-flight seek reads as
  "loading" instead of a frozen frame, and surface a fatal loadError even
  once playback has started. Spinner uses the shared Loader2.

Merges roadmap E6·item1 (spinner while loading/seeking) into this fix,
since the server-side warm-up deliberately holds ready a beat longer.

Tests: 3 new in test_plex_stream.py (warm-up waits for the first few
segments; stops at the first missing one; no warm-up when seg0 never
arrives). Gate: backend pytest 460 (Docker lane), FE tsc/lint/knip/
prettier + vitest 483.

peter 37d11b602f feat(plex): redesign browse tiles — 2-poster montage top, readable label band
The full-bleed 4-poster collage drowned the on-tile text. Split PosterTile in two: the top
half shows up to 2 montage posters, the bottom half is a solid colour-hash band that carries
the label, so the text is always readable. Genre tiles drop the count (just the label now);
collection tiles show the name on one truncated line plus a sub-line of item count · total
runtime. A group with no art falls back to an all-colour tile.

Backend: `/collections` cards gain `total_runtime_s` (a new `runtime_by_key` grouped sum) and
their montage art is capped at 2. Frontend: PosterTile reworked; a `collectionMeta` helper
builds the count·runtime sub-line via the existing formatRuntime.

Verified live: collection and genre tiles render 2 posters over a readable colour band with
the right sub-lines; colour fallback intact for art-less groups.

Gate: tsc/lint/knip/prettier clean, 423 vitest; backend ruff clean, collections tests green
(+ a new art/runtime assertion).

peter da3cb5e694 feat(plex): poster collages on the genre + collection browse tiles
The Browse-by-genre tiles and the Collections browse tiles were flat color-hash
gradients. Give each a 2×2 collage of its top films' poster art, with the color hash
kept as the fallback so a group with no matching art (a show-only or empty collection)
never renders blank.

Backend: a shared `top_art_keys` windowed query returns, per key (a genre value or a
collection rating_key), the top few items' rating_keys — best-rated then newest, in one
query. Wired into the Discover genre tiles and the collections union endpoint; the client
renders the posters from the existing /api/plex/image/{key} endpoint, so no new image
plumbing. Frontend: a shared PosterTile component (collage + scrim + label, color-hash
fallback) replaces the two ad-hoc colored-tile implementations.

Verified live on localdev: genre tiles and collection tiles render real poster collages,
with the color fallback correctly kicking in for groups without art.

Gate: tsc/lint/knip/prettier clean, 423 vitest; backend ruff clean, 11 discover tests
(incl. a new genre-art assertion).

peter a60164edc4 feat(plex): make the Collection filter multi-select with Any/All
A title can belong to several Plex collections, so the collection filter becomes
multi-select combining with Any (OR, default) / All (AND) — the same shape as the
genre/actor filters.

Backend (query.py): `collection` (single) → `collections` CSV + `collection_mode`
on LibraryFilters; meta_filter_conds ORs/ANDs `collection_keys.contains` per id.
Frontend: PlexFilters `collection`/`collectionTitle` → `collections` + optional
`collectionMode` + `collectionTitles` map; CollectionPicker is now a multi-select
Combobox with the any/all match footer; one chip per collection (usePlexActive-
Filters); the info-page "Browse collection" strip unions into the list; applyFilter
now shallow-merges label maps so adding one keeps the others' titles. PlexProvider
migrates a legacy persisted single `collection` into the new shape on read.

Test: test_plex_collections_filter (single / any-union / all-intersection).

peter bad2aae753 fix(e5): deep-review round — combobox Enter, parse_person collision, enrich hardening + coverage
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.

peter 13fb2b4e61 refactor(e5): deferred review-tail (backend) — enrich off request path, reuse, tests
Address the deep-review's deferred backend items so E5 is review-complete:

- person-enrich OFF the request path (ABUSE finding): person_detail no longer makes
  the TMDB call inline (even bounded to 8s it sat on the serve thread, un-throttled,
  demo-reachable — it violated the module's "no live TMDB call at serve time"
  invariant). It now schedules a FastAPI BackgroundTask (people._enrich_person_bg,
  fresh session, best-effort) after the response; the first open serves the row as-is
  and the bio lands by the next open. The inline try/rollback recovery is gone with it.

- reuse: a shared tmdb.resolve_library_guids owns the collision-safe guid→library
  bucketing (movie vs tv ids are independent sequences) that resolve_recs and
  people._resolve_known_for each hand-duplicated; a new rollup.item_state_map dedups
  the "PlexState-by-item_id" fetch across the person + discover paths.

- test gaps: enrich_batch transient TmdbError leaves the watermark NULL to retry;
  guid_to_tmdb_id resolves a tvdb source + tv media_type via /find's tv_results;
  _continue_watching includes a NULL-status started movie and excludes a hidden one;
  /api/search/youtube returns 422 (not 5xx) when ingest fails (route-level, B-core-1).

Backend lane 403 → 413, ruff clean. No migration; serve contracts unchanged.

peter 0c746f5bcd fix(e5): deep-review survivors — TMDB key log leak, person-enrich rollback + timeout
Three verified deep-review findings (the 4th, the filter combobox a11y gap, is
deferred to a dedicated session on the combobox architecture):

- SEC (medium): TmdbClient sent the api_key as a URL query param, so an HTTP
  error's httpx exception string embedded the full URL incl. the key, which
  enrich_batch logged. _get now raises status+path only (never str(e)/the URL)
  and severs the secret-bearing cause with `from None`. Regression test asserts
  neither the status nor the network error path contains the key.
- STATE (low): person_detail's lazy-enrich except now db.rollback()s, so a
  failed enrich_person commit can't poison the session and 500 the subsequent
  SELECTs (SQLAlchemy 2.x deactivates the tx on a commit-time flush failure and
  does not auto-reset it). Test locks that the page renders despite a poisoned
  enrich.
- ABUSE (low): the request-path lazy person enrich now caps its TMDB client at
  an 8s timeout (was the 30s default) so a slow TMDB can't tie up a worker;
  TmdbClient gained a `timeout` param (batch keeps 30s). The fuller fix (move
  person enrichment off the request path) is logged for later.

peter 2b5de89eda fix(e5): address code-review findings (TMDB guid media_type, search ingest guard, discover keying)
Follow-ups from the epic-end /code-review of the E5 branch:

- tmdb.resolve_recs + people._resolve_known_for: match recommendations/
  credits to the library bucketed by media_type. TMDB movie ids and tv ids
  are independent sequences, so a bare `tmdb:<id>` match could deep-link a
  movie rec to an unrelated show (or vice-versa) on a numeric collision.
  Regression test added (test_resolve_recs_matches_by_media_type_not_bare_id).
- routes/search: wrap the _ingest_candidates call so a DB/enrich failure
  degrades to a 422 with a message instead of a bare 500 hidden behind the
  FE's generic "search failed" (extends the B-core-1 rationale); rollback on
  failure. Stamp enriched_at with its own timestamp taken after the enrich,
  not the stub-insert placeholder.
- routes/plex/discover: key serialized cards back by rating_key (globally
  unique in Plex) instead of id(obj); fix the stale rows 3-tuple annotation.

peter 187b8007f8 E5 S6: enriched person page (TMDB bio + birth facts + Known-for rail)
The person page now leads with a TMDB bio, lazily fetched the first time it's
opened (off the S2-linked `tmdb_person_id`) and then served from the row:

- Migration 0072: ADD-only nullable person columns on plex_people — biography,
  birthday, deathday, place_of_birth, known_for_department, also_known_as,
  known_for ([{tmdb_id, media_type, title}]), tmdb_enriched_at.
- tmdb.py: TmdbClient.fetch_person (/person/{id}+combined_credits), parse_person
  (bio + a popularity-ranked, deduped known_for), apply_person, enrich_person
  (lazy one-shot, key+id guarded, commits, 404 stamps the watermark).
- people.py person_detail: loads the full person row, lazily enriches (best-effort
  — never fails the page), serves the bio fields + resolves known_for to library
  rows by guid (in-library only, popularity order).
- FE PlexPersonView: bio/birth-facts/aka hero + a "Known for" Carousel rail above
  the existing Movies/Shows filmography; PlexPersonDetail type + i18n (en+hu).

Tests: test_plex_person_bio.py (6: parse / lazy-enrich guards / serve) + extended
PlexPersonView.dom.test.tsx + the unknown-name contract in test_plex_person.py.
Browser-E2E'd on Jim Carrey (live TMDB enrich → bio 1937 chars, born 1962-01-17
Newmarket, Known-for resolved). Gate: vitest 337, backend lane 402.

peter f10915c223 E5 S5: enriched Plex detail page (ratings + facts + keywords + crew)
Consumes the TMDB block the S2 engine already persists + serves (movie/show
detail's `tmdb`), turning the movie info page into a Seerr-style enriched detail
(page variant only — the player overlay stays lean):

- Multi-source ratings row: IMDb (links out) · TMDb (with vote count) · Plex
  audience — whichever are present. Only the primary score (IMDb, else audience)
  carries the ratingMin filter, mirroring the backend rating column.
- Facts panel: release · runtime · cert · budget · revenue · studios · countries.
- Keyword chips → tap to filter the library. Backend: a new `keywords` filter on
  LibraryFilters + meta_filter_conds (`keywords @> [kw]`, both models), wired
  through PlexFilters (appendPlexFilters / plexFilterCount / active-chip / clear).
- Full crew (TMDB key-crew) → tap a name to open their person page.

Tests: test_plex_keyword_filter.py (3) + PlexInfo.dom.test.tsx (5, incl. the
overlay-stays-lean guard). New i18n plex.info.facts.* / keywords / crew / audience
(en+hu). Gate: vitest 337, backend lane 396.

peter f9b63745f9 E5 S4: Plex Discover rail-surface (default landing)
A dedicated Plex "Discover" landing — a stack of horizontal Carousel rails
served from ONE consolidated read (serve-from-DB, no live Plex/TMDB call):

- GET /api/plex/discover → continue_watching (in-progress movies + shows, most
  recently progressed) · recently_added · genres (top-N tiles) ·
  because_you_watched (recs of the most-recent watched, TMDB-enriched movie,
  resolved to library rows by guid via serve_block's resolver).
- GET /api/plex/surprise → a fresh random, scope-bounded sample for the ↻ rail.

Frontend: PlexDiscover.tsx (rails reuse the S1 Carousel + S3 PlexPosterCard;
colored genre tiles → tap to filter the grid; ↻ reshuffles the surprise rail
alone). Discover is now the root sub-view; the flat grid becomes the bookmarkable
"Browse all" secondary view (?v=browse) reached by a header search/filter (a
browse-intent flip) or the new Discover⟷Browse toggle.

resolve_recs is promoted from _resolve_recs (now cross-module). Tests:
test_plex_discover.py (rail shape/order, continue-watching, because-you-watched
+ null, surprise bounds, scope) and PlexDiscover.dom.test.tsx; plexSubUrl
round-trip updated for discover-root/grid-browse. Backend lane 393, vitest 332.

peter 5b5e76b73d E5 S3: unified Plex card — scrim-reveal hover + rest polish
The poster card (grid + person page) gets the Seerr-style hover: on hover a
bottom scrim slides up with the title, a "year · runtime · ★rating" meta line,
and a 3-line synopsis — the info you'd otherwise click through for — plus a
less-flat play ring (radial-gradient + ring shadow) and a top-right quick-action
cluster (Info + watched-toggle, revealed on hover / always on touch). Rest-state
badges (season / type tag) yield to the scrim on hover; the playable-cost tint
stays. (§1 A + C from the enrichment study.)

Backend (the data the scrim needs, mirroring S1's `art`): the grid
(browse.unified_library) now emits a lang-coalesced, truncated `summary` (new
query.summary_col) + the Plex `rating`; movie_card/show_card do the same (EN) for
the detail/related/person cards. PlexCard.rating type added (summary already
existed for episodes).

Gate: tsc x3 / eslint / prettier / knip / vitest 326 green; ruff green; backend
lane full suite green. Self-E2E on the live dev server (rebuilt on this branch,
S2-enriched): the grid serves rating+summary (Shawshank 9.3, Godfather 9.2, real
synopses) and the card renders the play ring + scrim (The Expanse: ring, synopsis,
★8.1) — verified via the DOM (the pane wouldn't composite for a screenshot).

peter 91be3d0535 E5 S2: prioritise TMDB crew, and capture the TV showrunner
A live smoke against the real TMDB API showed two crew problems the mocked
tests missed: (1) a TV show's creator/showrunner lives in the payload's
top-level `created_by`, not the crew list, so it was dropped entirely; and
(2) TMDB's crew order is arbitrary — a TV show's per-episode Directors (dozens)
flooded the key-crew list and buried the show-level roles.

Fix: split the accepted crew jobs by media type — movies key on
Director/Writer/…; TV keys on Creator (from created_by) + the show-level
Executive Producer/Writer/Producer/Composer, deliberately excluding the
per-episode Director/Editor/DP noise. Stored crew is sorted by display
priority and capped, so the lead roles come first.

Verified live: Breaking Bad -> [Gilligan (Creator), Johnson (EP), … , Writer];
The Godfather -> [Coppola (Director), Puzo (Screenplay), …]. test_plex_tmdb
green (9).

peter 3bde114b14 E5 S2: TMDB enrichment engine (Plex catalog)
Matches each mirrored Plex movie/show to TMDB by its stored canonical guid,
fetches once (append_to_response), and PERSISTS the enrichment onto the row —
served from the DB, never a live TMDB call at serve time. Additive: the
Plex-sourced imdb_rating/rating are untouched; tmdb_rating is the distinct
TMDb community score (ratings scope = TMDb + Plex's IMDb/audience, no OMDb/RT).

- config.py: tmdb_api_key + api_base/language/interval/batch defaults.
- sysconfig SPECS: tmdb_api_key (secret, Fernet) + tmdb_language, auto-rendered
  in the admin Config page; read like the Plex token.
- migration 0071 (ADD-only nullable, reversible): plex_items + plex_shows gain
  tmdb_id / tmdb_enriched_at (watermark) / tmdb_rating / tmdb_vote_count /
  budget / revenue / keywords / crew / studios / production_countries /
  recommendations / backdrops; plex_people gains tmdb_person_id (the S2
  foundation for S6 person bios). No watermark reset needed.
- app/plex/tmdb.py: TmdbClient (mirrors PlexClient; throttled; 404->None,
  transient->TmdbError), parse_tmdb / apply_tmdb_detail (one-parser rule),
  guid_to_tmdb_id (tmdb: direct, imdb:/tvdb: via /find), enrich_batch (movies
  then shows, transient error leaves the watermark NULL to retry, definitive
  no-match still stamps so it isn't re-fetched), _link_people (upserts
  tmdb_person_id by name), serve_block (recommendations resolved to library
  rows by guid), run_enrich (no-op without a key).
- scheduler: tmdb_enrich nightly job (default 120 min, no YouTube quota),
  runtime-tunable + "run now" from the Scheduler dashboard.
- detail endpoints emit `tmdb` (movies + shows) so it's curl-verifiable now;
  the FE render lands in S5.

Note: _link_people inserts plex_people rows for TMDB cast/crew; unreferenced
crew (composers etc., not in cast_names/directors) get pruned by the orphan
sweep — acceptable, the person page is cast-driven and cast rows survive.

Gate: ruff + py_compile green; backend test lane FULL suite 387 passed
(incl. migration drift downgrade->re-upgrade + test_plex_tmdb 9 tests).
Frontend unchanged since S1. Not merged (epic branch, stacks on S1).

peter fca3fa13ef E5 S1: shared Carousel primitive + Plex card-art serializer
Wave 5a building blocks under the Seerr-inspired Plex enrichment (E5).

Carousel (frontend/src/components/Carousel.tsx): the one horizontal-rail
component, replacing the hand-rolled `flex overflow-x-auto` strips and the
home of the future Plex-Discover rows. Edge-fade mask, hover/focus scroll
buttons that appear only on the clipped side (useHScroll — the X-axis twin
of useScrollFade, same watch-the-children discipline), native scrollbar
hidden behind .no-scrollbar, reduced-motion-aware paging. First consumers:
CastStrip + RelatedStrip now scroll inside it (dedup + free affordances).
New i18n: common.seeAll / scrollLeft / scrollRight (en+hu).

Card-art serializer (backend/app/plex/cards.py): movie_card + show_card now
emit `art` (the wide backdrop, /api/plex/image/{rk}?variant=art) so rails and
the crossfading hero get a landscape image with no per-item fetch — gated on
art_key so an art-less item stays null and falls back to the poster. FE type
PlexCard.art?.

Tests: Carousel.dom.test (children/header/see-all, clipped-edge buttons +
paging), test_plex_cards (art present/absent by art_key). Added a
ResizeObserver stub to PlexPersonView.dom.test (it renders CastStrip, now a
Carousel consumer).

Gate: tsc x3 / eslint / prettier / knip / vitest 324 green; ruff green;
backend test lane (docker-compose.test.yml) green on the plex card tests.

peter bc79720e81 fix(e3): address /code-review high findings (5)
Round-1 review fixes on the E3 branch:

- prune partial-fetch (correctness): `_paginate` now reports whether it reached
  the server's reported `total`; `_prune_stale` prunes only on a COMPLETE
  non-empty listing. A truncated fetch (a mid-sequence empty/short page before
  total — a transient Plex hiccup) no longer deletes the rows it merely failed
  to list. New test: a listing that claims 5 but returns 1 prunes nothing.
- `_prune_stale` (robustness): `stats.get("pruned", 0) + 1` — no KeyError when a
  caller's stats dict omits the key.
- service transitions (conventions): pause/resume/redownload use the JobStatus
  StrEnum instead of loose "queued"/"paused"/"error" literals, matching cancel.
- ffmpeg progress writer (correctness): a stuck-percent heartbeat now runs on its
  OWN 1/interval budget, so it can't consume the progress-write slot and delay a
  real percent change by up to an interval.
- backend/app/README.md (conventions): reword the transaction-ownership rule to
  quote and extend CLAUDE.md's canonical ("handler/job-wrapper commits; helpers
  flush; only quota owns its session") instead of stating a contradicting
  "helpers MAY commit" carve-out.

ruff clean, full DB-lane 364 pass.

peter 49011940d6 feat(plex): catalog prune — delete titles that disappeared from Plex (E3 S1, B-sub-6)
A sync was upsert-only: a movie/show/season/episode removed from Plex stayed
browsable forever and 404'd on playback. Each section now diffs the rating_keys
it just listed against the stored ones and deletes the stale rows (watch-state /
playlist links cascade via the existing FKs), mirroring the collections prune
that already shipped.

Safety: the prune is GUARDED on a non-empty listing (_prune_stale returns early
when `seen` is empty), so a transient Plex glitch that yields an empty page can
never mass-delete a library — the metadata is cheap to re-sync, an accidental
wipe is the only real risk. Shows prune leaf-first (episodes -> seasons -> shows)
so a stale row is deleted directly before its parent's cascade reaches it.

Out of scope (separate follow-up): library-level reconcile of a whole removed
section + retiring the dead `PlexLibrary.enabled` column.

Tests: movie prune + watch-state cascade, the empty-listing guard (mutation-
verified — removing the guard wipes everything), show/season/episode prune.
351 DB-lane pass, ruff clean.
