peter 8fb276aa90 feat(keys): j/k walk the feed, s finds the search box, g jumps to a module
A feed card cost ~10 Tab stops, so the tenth card sat ~135 Tabs from the top of the page, and the
only keyboard focus ring (a 60% accent outline on the thumbnail) all but vanished on the dark glass.
First slice of the E11 keyboard layer (S4a); Home, Plex and the tables follow in S4b/S4c.

- `lib/listNav`: one window listener over every registered list, walked in document order. `j`/`k`
  step item to item (on into the next list — owner decision D4), the arrows move around a grid, Enter
  clicks the item's own `data-nav-open` element, so it opens exactly like a click. An item root is
  never a Tab stop: it gets `tabindex=-1` only while the keyboard is on it, and keeps it until the next
  item takes it, so the player's focus restore lands back on the card. The first `j` takes the first
  card you can see, not the top of the list.
- `VirtualGrid` takes part with `keyboardNav` (column count + scrolling an unmounted row in);
  `VirtualFeed` turns it on, so the feed, the library and the channel page all have it.
- Keymap: two-step sequences (`g h`) whose pending step belongs to the scope that started it; the
  page-level scopes (`page`, `search`, `list`) are quiet while a layer that owns the keyboard is open,
  enforced in `dispatch`. A test pins the owner's rule that none of them needs a modifier on the
  Hungarian layout.
- `g h/f/c/p/x/n/m/d/s/,` jump to a module this account can reach; `s` focuses the header search box
  and selects the old query; Escape in it hands the keyboard back to the page (Plex's typeahead spends
  its first Escape on its panel).
- Hover popovers are passive layers: an open tooltip still takes Escape first but no longer silences
  the page keys.
- Focus ring (owner decision D2 = B): solid 2px accent around the whole item; the app-wide button/
  link/row ring goes from 60% to solid too. The item keeps a transparent resting outline because the
  video card transitions `all` — without it every `j` flashed a 3px white ring (measured in Chrome).
- Help sheet: the new keys, in a fixed order after the surface's own; a `g` chord only for a reachable
  module; opened over a player or dialog it leaves out the page-level keys and the context-menu key,
  which nothing can reach there (the latter pre-existing since E10).
- CLAUDE.md: a canonical-patterns row for list/grid keys (`useListNav` + `navItemAttrs` +
  `data-nav-open`, not a private arrow-key handler).

peter 78a9324381 fix(ui): the palette ranks what you typed, and lib stops leaning on components
Typing "theme" put the channel "The Meltzone Podcast" (matched only through its handle
`@themeltzone`) above every "Theme: …" row, and Enter opened the channel — the palette listed
matches in pure group order and always highlighted the first one.

- CommandPalette ranks each word: label starts with it > elsewhere in the label > only the hint,
  keywords or group name; an item ranks by its worst word, then the sum. The group order stays
  fixed, rows are ranked inside each group, and the best row overall starts highlighted. The
  highlight is held by id and follows the best match until the arrows or the pointer pick a row,
  so a channel list landing mid-typing no longer shifts it.
- A11y: result groups are `role="group"` named by their heading; `aria-expanded` is false with
  nothing to choose; the listbox stays mounted (hidden) so `aria-controls` never names a missing
  element, and "Nothing matches" sits outside it; a polite status announces the count once the
  typing pauses.
- `Column`/`FilterMap`/`filterRows`/`isActive` move from `ui/tableHeader` to `lib/tableColumns`,
  and the player's auto/loop modes from `playerModalControls` to `lib/playerModes` — three lib
  helpers imported the column contract from a ui component, and `playerModalHooks` its types from a
  feature component.
- eslint: `lib/` may not import from `components/` at any depth, type-only and re-exports included;
  the boundary contract test proves it fires. CLAUDE.md and the ui README say so.
- keymap: `dispatch`'s docblock sat stacked on `matchesShortcut`'s; moved onto `dispatch`.

peter 8a50538275 fix(ui): a write that fails says what failed and why, wherever it fails
`req` opens its blocking dialog for 400/409/422/5xx only. A 403/404/429 was left to the caller and a
502-504 or lost connection got just the self-clearing connection notice, so 34 mutations without a
reporting onError and 15 direct api writes with a bare or missing catch failed in silence: a hidden
channel that snapped back, a share link that never revoked, a confirmed account delete that ended
with nothing said.

- lib/queryClient: one MutationCache reporter. react-query awaits it BEFORE the mutation's own
  onError, so it waits a task and skips a failure the site already reported; the toast title comes
  from `meta.failTitle`, `meta.errorShownInline` opts out.
- notifyActionError: title names WHAT failed, the line under it says WHY (`failureReason`: a
  structured localized detail, else the status). It marks the error reported (`markReported`), so
  nothing reports one failure twice; `notifyKnownFailure` for a site's own specific sentence.
- Every silent site named (45 new HU/EN titles, 4 reasons). Stale "the global dialog shows it"
  comments corrected on the job actions, channel block, Plex sync, cookies, download enqueue,
  account delete and usePref.
- Channels passed the tag hook's channel id to the reporter as the error; the tag and priority hooks
  now report themselves, with the real error.
- A contract test keeps every useMutation naming its failure; CLAUDE.md gains the pattern row.
- history.dom.test: the "navigates only once the entries are back" assertion raced an async act's
  macrotask flush (1 in 5 runs); it now asserts from a later popstate listener.

peter b4aea7fa5b fix(ui): dialogs, menus and busy buttons keep the keyboard focus where it belongs
Measured in Chrome before each change:

- A dialog opened from a menu lost its focus: the menu row ran its action
  and closed in one batch, and floating-ui's focus return (a microtask)
  moved the focus to the row BEHIND the confirm dialog's scrim 7 ms after
  it opened, where Enter activated the row. MenuItemList now closes first
  and runs the action a task later; the dialog also captures the row, not
  a dying menu item, as its restore target.
- A side panel opened as a flyout collapsed the moment a dialog opened
  from inside it, unmounting the row the dialog hands the focus back to.
  useHoverFocusWithin holds while the focus is inside an aria-modal dialog.
- ui/Button's loading state set native disabled; Chrome moved the focus of
  the pressed button to <body> and never gave it back. Loading is now
  aria-disabled with a click guard that also cancels implicit submission.
- Escape/Enter in the playlist rail's rename field dropped the focus on
  <body>. The row refocuses from its ref callback when it re-attaches (a
  post-commit focus sticks; the earlier attempt ran before the button
  existed).
- PlayerModal was the one aria-modal shell without the dialog contract:
  it is now named by its title, traps Tab, restores the focus to its
  opener and shares one counted body scroll lock with every dialog.

peter 92c305bab9 fix(nav): a navigation closes every overlay before it pushes
The overlay history stack let a navigation land ABOVE open overlays and
"buried" their entries with a counter. Measured in Chrome: Shift+W over
About navigated under the still-open dialog, the next Back both undid the
navigation and closed About, and the Back after that did nothing; Shift+W
on Home with the player open did nothing at all. The counter could also be
spent by a different overlay closing first, and callers that could not
report whether they pushed were assumed to have.

setPage and openChannel now close every open overlay and push only once
the history is back in sync (one entry per live overlay, no programmatic
back() in flight, no reconcile queued), so nothing is ever buried and the
whole mechanism goes: navigateOverOverlays, closeThenNavigate, buryUnder,
setPage's boolean, and the three test files that pinned them. The palette
closes only itself before running a row, so a theme picked over the player
keeps the player. Shift+W on Home with the player open now closes it
(owner decision 2026-09-09).

The wait is on state, not on "a popstate": the old 250 ms fallback could
run with back()s still in flight. An overlay that refuses to close within
1.5 s drops the command instead of being navigated out from under.

peter 415a6c16f9 release: 0.84.0 — the owner's sixteen-item bug hunt
Sixteen items written from real use: eleven fixed, one measured and closed without a code change
(the micro-stutter is a 23.976 fps film on a 120.0148 Hz display, reproduced identically outside
Siftlode), two parked for a reproducible case, one scoped out to its own sprint. Two of the eleven
were destroying user state — a YouTube video that rewound itself on reopen, and a "clear resume
point" that told Plex nothing about an in-progress item.

Then seven deep-review rounds over the fixes and over each other's fixes: 32 → 24 → 43 → 31 → 22 →
26 → 18 raised. Minor, not patch: item 14 added an admin knob, item 10 a sort control, and items
2/4/5/7 are features.

peter 8c51062e5b fix(api,ui): the demo refusal says why at every site, and the contract guard cannot fail open
Round 6 converted three of four `is_demo` 403s to a structured detail and wrote a docstring saying it
had converted all the sites there are. The account-delete route in `routes/me.py` still answered a
hand-written English sentence, which `notifyActionError` discards in favour of the caller's
translated fallback — so the demo user gets no hint that the demo account is the reason. It is
UI-gated today, so the string is unreachable; what was reachable was the false completeness claim,
which is precisely what stops the next reader from looking. The site is converted, and the list is
now DERIVED from the source: a new test walks `app/` for every `is_demo`-guarded 403, asserts each
raises a structured detail, and fails when the count moves — so this file cannot fall behind the code
the way it just did.

The same round's frontend contract guard was failing open. Its pattern required a bare identifier
before `.detail` and excluded `.detail` used as a last call argument, so `setErr(e.detail)`,
`(e as HttpError).detail`, `String(e.detail)` and four more idiomatic forms were invisible — and
because the file set is compared with `toEqual`, a file the pattern cannot see is simply never listed
and the gate stays green over a fresh copy of the contract. Widened to cover cast receivers, optional
chains and call-argument reads; the pinned set is unchanged, so the narrowing had removed no false
positive. A destructured `detail` stays out of reach (a pattern loose enough for it fires on
react-query's own `const { data: detail }`), and that hole is written into the test rather than
papered over with two innocent files.

Its anti-vacuity guard also did not guard anything: the comment says the glob must have matched
something, but the assertion under it read a sibling file by its own URL, which resolves whether or
not the glob enumerated anything. That only mattered while the pinned list was non-empty — the moment
the deferral sweep lands and it becomes [], the whole file would pass over a glob matching zero
files. The scan size is asserted now.

peter 63bf1bca78 fix(plex): an accepted reorder refetches the detail it just wrote
`commit`'s success handler writes the dragged list into the detail cache — round 6's fix, so a
re-entry inside the 30s staleTime renders the accepted order without a request — but then invalidated
only the LIST key, while the YouTube sibling it cites invalidates both. `next` is the membership of
the render that started the drag, and `reorder_playlist` only touches the rating_keys it is handed,
so it never ratifies that list: anything that landed meanwhile was clobbered by the write with
nothing scheduled to correct it. `commit` sets no busy flag either, so a removal really can complete
while a reorder is in flight, and with staleTime 30s and refetchOnWindowFocus off the phantom row
stayed on screen for as long as the view was mounted — and the next drag persisted an order built
from it.

Round 6's test had to be re-pointed, because it was written in a world with no refetch: its mock
answered the pre-reorder order forever, which a server that just accepted the write cannot do. It now
holds the refetch open instead, so it still pins what round 6 actually fixed — the cache is right
WITHOUT waiting for a request — and would fail if the write were deleted. Both halves are
mutation-checked against each other.

peter c7a377396b fix(ui): a closing dialog leaves the focus to the dialog standing above it
Round 6 widened dialog focus ownership to count focus inside ANY `aria-modal` subtree as ours, so a
dialog and the dialog stacked on it closing together would still hand the focus back. That clause has
no way to tell a layer closing WITH us from one that stays open, so a dialog closing on its own — an
in-flight mutation's `onSuccess`, not a click, since a scrim covers it — under a modal raised above it
pulled the focus onto its own pre-open trigger, behind that scrim, where Enter still activated it.
Three verifiers confirmed the mechanism and two corrected the severity down: it self-heals on the
next Tab, which is why this is a containment violation rather than a broken end state.

`lib/layerStack` cannot refine it. Measured against the real hook: at the instant the lower dialog's
focus cleanup runs, the both-closing case and the sibling-stays-open case give identical readings —
`anyLayerAbove` true, the upper layer topmost — because passive cleanups run parent-first and
`useDialogChrome` is declared before the effect that calls `removeLayer`. Gating on the stack turns
round 6's own test red. What separates them is the DOM: React detaches a deleted subtree before
passive cleanups, so a layer closing with us is already disconnected while one that stays open is
not. Both tests are green, and each was mutation-checked against the other.

Verified in Chrome on localdev: opening the cheat sheet from a sidebar button and closing it restores
that button; with the command palette stacked over the cheat sheet, closing the top one leaves the
focus neither on the background trigger nor on <body>, and closing both returns it to the trigger.

Welcome's Lightbox got the trap and the restore in round 6 but not the layer membership the other
shells have, so its Escape and Tab fired from a raw window listener whatever was on top — the shape
the wizard's comment records being bitten by, unreachable today only by a mount ordering nothing
enforces. It joins the stack. Its comment also read as though the four-shell sweep were finished:
`PlayerModal` is still an `aria-modal` surface with no name, no trap and no restore, which is on
ROADMAP.md now rather than implied to be done.

peter 8036251589 fix(plex): the reclaim window rolls, and a refused finish is not performed through a third route
Two ways round 6's own fixes did not bound what their comments said they bounded.

The reclaim budget's window anchor was written only where the window RESET, so it marked the window's
start rather than the last loss — a tumbling window, not the rolling one the constant is named for.
Any loss cadence slower than half the window satisfied the reset on every second loss, so the budget
never reached its bound: measured over 200 loss cycles, 61/70/90/119s apart all gave 200 reclaims and
never an error, while 5s and 30s apart correctly gave two and then the honest answer. The failing
band is exactly the case the ERROR handler names — a transcode that falls behind realtime — and both
committed tests spaced their losses 0s and 10min apart, i.e. outside it. The anchor now moves with
every loss.

And `finish`'s refusal handler lowered the play-through latch, which is the only gate on the 10s
interval, the page-hide beacon and `settle`. All three post `absRef`, which on the play-to-the-end
path IS the end of the media, and the backend reads a position within `_FINISH_MARGIN_S` of the
duration as a finish — so within ten seconds of the toast saying the mark had failed, the item was
marked watched, its position cleared and a scrobble sent to Plex. Round 6 closed the explicit
rollback write and left the other three open; the test it added set `upNext: false`, which tears the
effect down before any of them can fire. The refusal now takes back the CLAIM rather than the latch:
a second flag stops `settle` re-asserting watched, and playing again clears both.

`FINISH_MARGIN_S` duplicated the backend's constant in a second language with nothing relating them,
and its comment had the asymmetry backwards — if the BACKEND's margin grows, this guard starts
admitting a rollback the backend reads as a finish, i.e. re-opens the defect above. Pinned by a
contract test that reads the Python, and the comment corrected.

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 3eb0f41962 fix(plex): a Plex reorder the server accepted is the order the cache holds
The YouTube list got this rule in round 5 — one accepted write, one cache entry
that matches it — and the Plex list got only the rollback half of that fix. Its
success path invalidated `qk.plexPlaylists()`, a disjoint key root, and never
touched `qk.plexPlaylist(id)`: the key `putBack` rolls back to, and the one a
re-entry renders from without refetching.

So after an accepted drag the detail cache still held the pre-reorder order.
Leaving the playlist and coming back inside the 30 s staleTime showed the
reorder undone, and the next drag from there persisted that — silently undoing
an order the server had taken. Measured in jsdom: server 2,1,3, cache 1,2,3, no
refetch.

1 test, mutation-checked.

peter a0114deff1 fix(api,ui): a refused write says why, wherever the refusal happens
Round 5 taught `notifyActionError` to discard a plain-string `detail` in favour
of the caller's translated fallback, because `req` leaves 403/404/429 to the
caller and those routes hand-write English. Three places did not get the
message.

**The demo account lost its explanation.** `require_human` refused with a plain
string, so from that commit on the shared demo account got its caller's generic
"couldn't do that" and no hint that the demo account was the reason — and the
gate is not backed by a UI gate everywhere: the comfort shelf has no `is_demo`
check, so the pin button is live and simply fails. A structured `{code: "demo"}`
and an `errors.demo` string in both locales. The two auth routes that hand-roll
the same check were swept with it.

**`ChatThread` carried a second copy of the contract.** It filtered 404/429
itself and then did `e.detail || t(…)`, the pre-fix order, so the central fix
could not reach it and "That member hasn't set up messaging yet." stayed English
under a Hungarian UI. It goes through the shared helper now, and a contract test
pins the remaining raw-`detail` consumers as an explicit SET — never a count —
so a new copy fails the gate instead of shipping. The five on that list are
inline surfaces (a form field's error line, a setup banner) and are deferred
with the ~60 backend routes whose details they print.

**The Plex "Add to playlist" dialog was still silent.** Same shape as the
collection editor round 5 fixed and the YouTube twin that already had the fix:
no catch, so a playlist deleted on another device answered a structured 404 that
nothing reported — the tick never flipped, the gone row stayed, and the floating
promise became an unhandled rejection.

Also: the `ABORTED` sentinel's VALUE was asserted nowhere. The consumer test
hand-built the error it expected, so replacing `xhr.onabort`'s rejection with a
friendlier message left the lane green — and every upload the user cancels would
then raise a red "the upload failed" toast, which is what the sentinel prevents.
Both producer tests assert through `isAborted` now.

And two backend tests were pinning fewer sites than their own docstrings claimed:
the channel-404 loop said "all five" and issued three requests (explore and
subscribe unexercised, the excuse for subscribe naming a different call site
with a different reason slug), and the recipient/job test named three refusals
and requested two — `share_download`'s `not_found("recipient")` had no test in
the suite at all, nor did the locale keys added beside it. Every site named now
has a request behind it.

6 tests, mutation-checked against 7 mutations: the demo detail at both the gate
and an auth route, a re-hand-rolled ChatThread, the silent Plex dialog, the
abort sentinel, and each unpinned 404 — all red on the test that names them.
2026-09-12 05:50:31 +02:00
peter d89d887a9b fix(plex): the reclaim budget bounds what it says it bounds, and a refused finish is not performed anyway
`MAX_SESSION_RECLAIMS` was cleared by the first fragment of any session, and a
reclaimed session essentially always delivers one — `start_session` does not
return until its first segment exists. So the budget only ever bit where a
session parsed its manifest and then died before a single fragment, which is not
either case its own comment names. Measured: 40 loss cycles produced 41 sessions
and never an error. A transcode falling behind realtime, or two viewers of one
rating_key taking turns, respawned ffmpeg indefinitely — the round-5 behaviour,
still there behind the guard added to stop it.

It counts within a rolling window now. Two losses inside two minutes is a
session that keeps being lost; one an hour apart is not. And the window is reset
per item, because the player stays mounted across a queue advance — otherwise a
budget spent on one episode would deny the next its first legitimate reclaim.

Separately: `finish`'s rollback re-performed the write it was taking back. On
the play-to-the-end path the position it restores IS the end of the media, and
the backend reads a position within its finish margin as a finish — so the
branch named "take the finish back" set watched, cleared the position and
scrobbled to Plex through a second route, while the caller's error toast was
already on screen saying the mark had failed. There is no resume point at the
end of the media to restore; the cache drop is the whole of the rollback there.
The credits-skip caller captures a mid-episode position and still restores it,
which is the case that needs it.

7 tests, mutation-checked: the FRAG_LOADED reset, the missing window, and the
unguarded rollback each red on the test that names them.

peter f8a31d48cf fix(ui): a dialog keeps the focus it was given, and hands it back where it took it from
Round 5 extracted `ui/dialogFocus` so no shell would hand-roll the focus
contract, then introduced four ways to lose the focus anyway — all four measured
in jsdom against the real components.

**Ownership was narrower than the trap.** `ui/Modal` traps Tab over the whole
dialog on purpose, so a toast's Undo or ✕ stays reachable; ownership was tracked
over the panel alone. Tabbing to that ✕ therefore read as "the user left the
dialog", and since removing a toast fires no `focusin` to re-arm, closing
afterwards skipped the restore and left the focus on <body>. Before this hook
existed the restore was unconditional, so it was a regression.

**A dialog stacked above us is still ours.** A nested `ui/Modal` portals into its
own host, so it is outside the outer dialog's root however wide that scope is
drawn — widening alone could not fix it. Both closing in one commit left the
focus on <body>: the outer skipped its restore, and the child's own target (a
control inside the outer panel) was already detached, because passive cleanups
run parent-first. Ownership now means "inside my dialog, or inside a modal layer
above it", which is what the rule always intended.

**The wizard disagreed with `ui/Modal` on its first line.** `trapTab(e, panel)`,
with neither the dialog-root scope (so its own toast host was outside the cycle
— the connection notice never auto-dismisses, and its ✕ was unreachable from the
keyboard) nor the `container` argument the JSDoc exists for: `panel.contains(
panel)` is true, so focus sitting ON the tabIndex=-1 panel matched no branch and
a Shift+Tab walked into the app behind the scrim. Both call sites now pass the
same three arguments.

**The toast handover was a render-phase read-modify-write.** A `useMemo` read a
module global that the next line overwrote; React re-invokes a component body
and every `useMemo` factory in it on a StrictMode double render, and the LAST
invocation commits — so the second pass re-read what the first had just written,
the takeover host classified its OWN new toast as inherited, and the dev build
behaved exactly like the code round 5 replaced. Snapshotted through a ref keyed
on `isTop`, so a repeated invocation of one render is a no-op.

And the fourth `aria-modal` shell, `Welcome`'s screenshot lightbox, is finally
swept into the same contract: it declared itself a modal dialog while leaving
the focus on the thumbnail behind an 80%-black scrim and letting Tab walk the
landing page underneath.

The headline fix of the previous commit — StrictMode's re-mount taking the focus
off an `autoFocus` field — had no test at all; deleting it left all 1009 green.
It has one now.

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 33fddacee2 test(plex): the over-long-name guard is asserted the same way on every OS
Deep-review round 5. The assertion behind `subtitles._exists` was only red where pathlib re-raises
ENAMETOOLONG: on Linux it does, on Windows the same stat fails with ERROR_INVALID_NAME, which
pathlib's `exists()` already swallows — so the assertion passed with the fix reverted. It forces the
errno now instead of relying on the filesystem. (The gate's pytest lane is the Linux container, so
the branch was never actually unguarded; the test was just dishonest about why it passed.)

peter 12121255dd fix(playlists): a rejected reorder goes back to the order the server accepted
Deep-review round 5, over round 4's own fixes.

- Round 4 made a failed reorder roll the rows back to the CACHED detail, because a resync cannot do
  it (the server's list is unchanged, so the refetch is deep-equal, react-query keeps the same
  `data` object and the effect keyed on it never runs). But nothing wrote an ACCEPTED order into
  that cache — only the refetch that follows a successful reorder did. So a second reorder rejected
  while that refetch was still in flight rolled the rows back past the first one, which the server
  had accepted; the membership guard cannot correct an order (its key is the sorted id set), so the
  wrong order stayed on screen for good and the next drag persisted it. `onApply` now writes the
  accepted order into the cache before invalidating.

- `PlexPlaylistView.rename` had a `catch` no test could reach, and `commit` (reorder) was not gated
  by `busy` the way its siblings are — a reorder in flight while a removal completes is what makes a
  rollback ambiguous in the first place. The rename failure path is now covered; `commit` defers.

- `putBack` read `q.data` from the render that bound the failing handler instead of the cache at
  rollback time, unlike the sibling `restoreFromCache`. Aligned. Stated plainly: I could NOT drive
  that staleness in jsdom — a mutation that restores the old shape leaves every candidate test green
  — so this one ships as an alignment with the proven sibling, not as a fix with a red test behind
  it. The scenario and the harness limit are on ROADMAP.md.

Two regression tests, both mutation-checked red (the cache write, the rename catch). The
drag-reorder failure path still has no test: dnd-kit's pointer and keyboard sensors do not activate
under jsdom even with geometry and scrollIntoView stubbed, so a test there would have pinned the
harness, not the code. Logged, not faked.

peter 4a7b65d187 fix(api): a refused write is named, in the reader's language
Deep-review round 5, over round 4's own fixes.

- `notifyActionError` preferred the server's `detail` over the caller's translated fallback, and
  `reportFailure` deliberately leaves 403/404/429 to the caller — so for exactly those statuses the
  dozen call sites round 4 converted started printing whatever English a route hand-wrote into an
  otherwise Hungarian UI ("No user with that email.", "Not subscribed to this channel", "Unknown
  job"). A STRUCTURED detail is still preferred: `req` has already run it through `localizeDetail`,
  so it is both localized and more specific. A plain string is not.

- The other half of the same defect, on the backend: round 4's `get_or_404(what="channel")` sweep
  reached exactly ONE of the five identical sites in channels.py and shipped the HU/EN string with
  it, so the Block button said it in Hungarian and the four controls beside it in English. All five
  are converted, and the subscription / share-recipient / scheduler-job 404s with them (two new
  reasons in both locales).

- `PlexCollectionEditor`'s add/remove, take-over and delete were try/finally with no catch — in the
  very file round 4 edited to give `createNew` one. 403 and 404 are the caller's to report, so the
  tick simply never appeared and a CONFIRMED "delete collection" did nothing, silently.

- `UploadDialog` is the only `uploadReq` caller and kept an empty catch whose comment still claimed
  the global error modal had it. It had not since `reportFailure` became shared: a proxy 502 raised
  only the self-clearing connection notice and a 413/403/404 nothing at all, so the dialog snapped
  back to its pre-upload state with no error named. The user's own Cancel stays silent — and since
  a cancel and a network drop both carry status 0, that difference is now a named `isAborted`
  rather than a string literal at each end.

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.

peter 8a83bc0e9f fix(plex): a finished item is finished when the server says so, and a lost session is reclaimed a bounded number of times
Deep-review round 5, over round 4's own fixes.

- Round 4 added a `finish` latch so a played-through item records no checkpoint at the credits.
  On a NATURAL play-through it was raised a beat too late: per the HTML spec the browser sets
  `paused` and fires 'pause' BEFORE 'ended', so the pause checkpoint went out while the latch was
  still down and raced the watched mark — both requests read "not watched yet" from their own
  snapshot, so Plex counted one watch twice, and where Plex's reported duration runs more than the
  finish margin past the real media the checkpoint wrote a resume position AFTER the scrobble. The
  pause that ends the media no longer flushes. The regression test that was meant to cover this
  modelled the end as a bare 'ended' event — a browser that does not exist — and is now the real
  order.

- The watched mark was fired and forgotten (`.catch(() => {})`) while the latch patched the cached
  detail to watched / position 0 regardless, and round 4's once-per-id start guard meant the
  corrected detail arriving later was never used: an episode whose mark failed reopened at 0:00
  with a Watched badge the server disagreed with. `finish` now takes the in-flight write and takes
  itself back if the server refuses it — the real position is reported, the lying cache entry is
  dropped, and the failure is said out loud instead of swallowed. Both callers (the natural end
  and the credits auto-skip) hand it over.

- The reclaim of a 404'd HLS session had no bound. `parsed` cannot provide one — it belongs to one
  hls instance and every restart builds a fresh one — and the server answers 404 both for "the
  session is gone" and for "that segment is not there yet", so a transcode falling behind realtime,
  or two viewers of one item taking turns, respawned ffmpeg forever behind a spinner that never
  became an error. Two consecutive reclaims, reset by the first fragment that actually loads, then
  the honest failure.

Five regression tests, each mutation-checked red on the assertion it is named after.

peter 41b652f8fd fix(ui): a dialog opens focused where it said it would, and the wizard is a dialog
Deep-review round 5, over round 4's own fixes.

- Round 4 gave `ui/Modal` a persistent portal host so a fullscreen transition would stop tearing
  the dialog down. The host was attached in a `useLayoutEffect` — one commit phase AFTER React
  runs `autoFocus` in `commitMount`, and `focus()` on a disconnected node is a no-op. Every
  autoFocus in every dialog was dead: Mod+K opened the command palette with the focus on the ✕,
  so typing searched nothing and Enter closed it; the same for the download rename field and
  every non-danger confirm. The host is attached in a `useInsertionEffect` now, a whole phase
  earlier, and the whole re-parent — including the focus save/restore across the move, which
  `appendChild` needs because it is remove-then-insert — lives in one `useFullscreenPortalHost`.
  `ui/AnchoredPopover` had a second copy of that re-parent WITHOUT the focus restore, and a
  comment claiming focus survived it; both now come from the hook.

- `ui/Toaster` classified a toast raised in the SAME commit as a host takeover among the ones it
  inherits, because it read the store live at the takeover render. A dialog that notifies and
  closes in one handler (UploadDialog) therefore put its toast up with no role, into a region
  still `aria-live="off"` — announced by neither path. "Inherited" is now what the outgoing host
  last had on screen, and a toast that is NOT inherited is announced even inside the unarmed
  window.

- The onboarding wizard renders its own shell, and Escape ordering was all of the dialog contract
  it had: no role, no label, no initial focus, no trap, no restore. A keyboard user tabbed out of
  the first-login wizard into the app behind the scrim. The focus half of the contract is now one
  shared `ui/dialogFocus` that both `ui/Modal` and the wizard use.

Every fix has a regression test, each mutation-checked (6 mutations, all red on the assertion
they are named after).

peter 545996f807 fix(ui): a toast host ranks by when its overlay opened, and an overlay keeps its Escape, its dialog and its navigation straight
Deep-review round 4, the overlays.

- Toast hosts were ranked by mount time, and PlayerModal swaps its host on every fullscreen change:
  leaving true fullscreen with the download dialog open put the player's host back on top, so toasts
  were drawn under that dialog's scrim and a click on one closed the dialog. Each overlay takes a
  rank once, when it opens (`useOverlayOrder`), and hands it to every host it renders.
- A dialog open while fullscreen is left keeps a stable portal container (moved, not re-created):
  React tore the portal down when `fsRoot` changed, resetting a half-filled form and dropping focus
  to <body>. Focus is put back after the move.
- The onboarding wizard is a layer, not a raw document listener: one Escape used to dismiss the
  error dialog over it AND end onboarding, skipping the write-scope step.
- `navigateTo` (a toast's "View", clicked inside the player's own host) goes over the overlays it
  unmounts, so the player's Back-to-close cleanup no longer pops the page it just opened — the same
  fix Shift+W already had. The access-requests toast action too.
- The live region arms itself a task after it takes over inherited toasts: React flushes effects in
  the same task as that render, so the "silent inheritance" arming was a no-op.
- The overlay-host guard matches class tokens in any order (PlexPlayer's root was never checked),
  globs `ui/` too (ui/Modal was not checked either), and requires the rank.

peter 267fd7f70f fix(playlists): a refused edit is taken back on screen, and a gone list or tag is said, not swallowed
Deep-review round 4, the playlist surfaces.

- A failed move or reorder relied on the resync to put the rows back — but the server's list is
  unchanged, so the refetch comes back deep-equal, react-query keeps the same `data` object, and the
  re-seed effect keyed on it never ran: the moved row stayed gone, the rejected order stayed on
  screen. Both restore from the cached detail now.
- A failed removal puts its row back itself: when the server is unreachable the resync fails too,
  and round 3's "keep the list on a failed refetch" guard then kept showing it as removed.
- The Plex playlist page (remove / rename / delete / reorder), the add-to-playlist popover and the
  tag manager had no failure handling at all: a list or tag deleted elsewhere (a 404, now a
  structured `not_found` the request layer leaves to the caller) failed in silence and an
  optimistic removal stayed removed. Each says it and resyncs; deleting a Plex playlist that is
  already gone just leaves the page.
- Playlists' own loading/error branches use the shared `LoadingState` / `StateMessage` (the loading
  line had no live region).
- The "player stays mounted" tests count mounts: a remount ended with the same flag as staying up.

peter 6d49da17fe fix(api): a write that hit a connection failure is still reported, and every failure is reported once
Deep-review round 4, the "one report per failure" contract round 3 introduced.

- `req` marked gateway (502/503/504) and network failures "already reported" because they raise
  the connection notice. But that notice is about connectivity and removes itself on the very next
  answer — which every caller's own resync refetch fetches at once — so a delete that hit a
  keepalive reset flashed the notice and was then reported nowhere, the list still there. Only the
  durable reports (the error dialog, the 401 sign-out) count now; the caller says the action failed.
- A connection notice the user closed swallowed every later one for the rest of the visit; it is
  raised again.
- `req` and `uploadReq` share one failure policy (`reportFailure`). The upload copy had drifted: a
  502 opened the blocking "Server error (502)" dialog and cleared a notice that was still true.
- A taken Plex collection name is a structured 409, localized, and the create/rename calls are
  quiet: it was an English dialog plus a Hungarian toast. `notifyCollectionEditError` is gone.
- The mutation onErrors that toasted unconditionally after a non-quiet request (invite approve /
  deny / add, demo whitelist, audit clear, scheduler, share, full history, edit, config tests, tag
  attach) go through `notifyActionError`; the playlist delete's hand-rolled copy of it too (it takes
  a level now). The user role / suspend / delete actions had no onError at all: a user deleted in
  another tab failed silently and stayed listed — now said, and the list refetched.

peter 6a92585098 fix(plex): the player restarts a reaped session, finishes a played-through item as watched, and starts each item once
Deep-review round 4, the Plex player.

- A 404 on an HLS session that WAS playing means the server reaped it (a long pause, a deploy);
  hls.js never retries a 4xx, so playback ended with "couldn't play". A new session at the playhead
  now takes its place (the frontend half of the paused-viewer reap fix). A session that 404s before
  its manifest is still a plain failure, so it cannot restart itself in a loop.
- Leaving an item that ended, or that the credits auto-skip left, sent a final checkpoint at the
  credits (racing the watched mark, and pushing a resume point to Plex after the scrobble) and
  patched "new, at 49:55" into the cache — Prev reopened it at its last seconds. `finish` settles it
  as watched at 0, said before the pause whose own checkpoint could land first.
- An audio switch, an A/V offset change and every seek control read `abs`, which is 0 until
  playback ticks: a resume at 20:00 restarted from 0:00. They use the shared `playhead`.
- A seek while a restart is pending always restarts (the old media's `seekable` described the old
  session, and the pending answer overrode the newer seek).
- A superseded direct-play session's loadedmetadata/canplay are generation-gated and detached (they
  seeked the next item to the previous one's resume point).
- The session starts once per item: a reconnect refetch, the info panel's watched toggle or a
  language switch no longer restarts the film at the last checkpoint.
- Tests for the session generation's failure paths and the item-change bump, which had none.

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.

Deep-review round 3 of bug hunt 2026-09.

- The YouTube and Plex progress bodies are bounded by POSITION_MAX_S (the int4 position columns): a
  finite position of 2^31 or more was a DataError, i.e. a 500 — the sibling of round 2's non-finite
  fix.
- plex/stream.py promised "a periodic reaper", but reap_idle ran only inside the NEXT session
  request: after the last playback an abandoned session (its ffmpeg still working, its directory a
  whole segmented copy of the film) lived until someone pressed play again. A lifespan task reaps
  every 60 s.
- Tests for what round 2 left untested: the 422's body keeps the list shape the UI localizes, and

Discover's toggle flips the Surprise draw too, but its resync refetches only the rails (refetching the

toggle invalidates the Surprise key now says what the code does.

Deep-review round 3 of bug hunt 2026-09.

- The detail's error branch applies only when there is nothing to show (`isError && <no data>`, the
  QueryState convention): one failed refetch — on focus, after a move or a removal — replaced a
  loaded list with "couldn't load". The error line is announced (role=alert).

Deep-review round 3 of bug hunt 2026-09.

- get_or_404 / owned_or_404 answer a structured {code: "not_found", reason: <what>}
  (errors.notFound.* in HU+EN, generic fallback). The structured-404 fix of round 2 had gone into the
  ad-hoc `_own_playlist` (CLAUDE.md's "Not" pattern) while the shared helpers stayed string-only, so
  views, tags, pins, Plex playlists, invites and users still 404'd in English. `_own_playlist` now
  goes through owned_or_404; admin's hand-rolled user lookups use get_or_404.
- A move into a list that is gone names the TARGET (reason "move_target") — "this playlist doesn't
  exist any more" was read as the list on screen, which still exists.
- Every refusal in the playlists router is a {code: "playlist", reason} (playlists.errors.* HU+EN)
  instead of a bare English string shown verbatim in the Hungarian UI.
- `req` / `uploadReq` mark the errors they already put on screen (the error dialog, the connection
  notice, the 401 sign-out), and notifyActionError skips those. The watched toggles, the saved views
  and a playlist delete toasted a fault the dialog was already showing; Playlists' two hand-written
  status filters now go through the same check.

Deep-review round 3 of bug hunt 2026-09 (the round-2 overlay toast host, finished).

- Inside an overlay the toast stack sits above the bottom band (bottom-24, the UpNextCard rung) and
  lets clicks between cards through: at the app's own spot it covered the Plex transport row and
  PlayerModal's docked bar and took their clicks while a toast was up (measured: play/pause, ±10,
  stop, prev/next, mute all hit the toast).
- ui/Modal and the onboarding wizard mount an overlay host too, so a toast raised under any dialog
  is readable and a click on it no longer closes the dialog; the Modal's Tab trap spans the whole
  dialog, so a toast's action and dismiss are keyboard-reachable. A test now enforces the
  convention: a component that covers the viewport at z-overlay must mount <Toaster overlay />.
- PlayerModal's host moves into the stage in true fullscreen (outside the element holding the lock it
  was painted under it).
- A host that takes over shows the toasts it inherits silently (no second role=alert, its region
  aria-live=off until they are in), and each countdown bar starts as far in as its toast already is
  instead of restarting while the real dismiss timer does not.
- The overlay-host registry uses lib/store instead of a hand-rolled listener triad.

peter 5c5cabbe5a fix(plex): the player drops a session answer that lands late, and Next neither loses nor lends a position
Deep-review round 3 of bug hunt 2026-09.

- loadSession checks, after its await, that it is still the newest call and the player is still
  mounted. A late answer used to replace what was playing (Next twice quickly: the slower transcode
  landed last and played the middle item under the last one's title, recording its progress there)
  or attach a stream to the detached <video> after Back, never destroyed.
- The <video>'s clock is trusted only once the new session has answered. go()'s pause() fires a
  timeupdate AFTER the reset to 0 (measured in Chrome), so the previous item's position was sent as
  the next item's subtitle position and saved as its progress (final, pushed to Plex).
- Next settles the item being left (final checkpoint + reopen-cache patch) before switching: the
  progress cleanup ran with the position already reset and skipped, so every Next dropped the last
  stretch watched.
- A seek-restart puts its target into the position state too; the ref alone was re-synced back to
  the pre-seek spot by the restart's own render.
- The unmount teardown captures the <video> at mount: React detaches refs before an unmount's
  cleanups, so the stop/detach never ran.
- The tracks panel exposes the selected audio/subtitle track via aria-pressed.

Verified in real Chrome on localdev (Westworld S1E6 → Next): the item left was settled at 783 s, the
next asked for subtitles at its own start (0), and no progress was written for it.

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 f7faa19ee2 fix(plex): the player starts, and resumes after a session-restart seek, when React mounts it twice
The player's "still alive" flag — every play() is gated on it, so a late one cannot start a detached
<video> after Back — was only ever LOWERED, in an effect's cleanup. React may run a cleanup and mount
again (StrictMode does exactly that in development), and then the flag stayed false for the life of
the player: it never started by itself, and a seek back past the loaded region, which restarts the
session, left it paused. Found on localdev (Westworld S01E06: playing → seek back → the picture
settles, paused). Production does not double-mount, which is why only dev showed it — and why
several earlier localdev measurements "stayed paused".

The effect now raises the flag in its setup. A new test renders the real player under StrictMode and
checks it plays once the media is ready; red without the fix. Verified on localdev: it starts by
itself, and keeps playing through a backward session-restart seek.

peter 0b4b268678 test(feed): pin the sort options' default directions as literals
The feedSortOptions test compared each option's default direction against SORT_DEFAULT_DIR — the
implementation's own table, so a wrong entry passed — and that import was the export's only user
outside its module, which kept knip from seeing it had become dead after F3. The test now states the
directions, the table is private again.
2026-09-11 03:19:17 +02:00
peter d349bc9084 fix(plex): a collection's failed watched toggle is put back the way it was
C1 moved the optimistic flip onto the key the page reads — and so made visible that nothing corrects
it: the resync only invalidated `plex-library`, so a failed toggle stayed "watched" beside its own
error toast, and the collection's other cached sort orders stayed stale after a good one. The
resync now takes this page's `detail` prefix too, as the Discover and person pages do for theirs.
The C1 test holds the request open, so it still pins the optimistic write on its own.

peter dcd8a9566a fix(playlists): the player's Remove follows the list it was launched from, the player survives a change of selection, and a gone list is said in the reader's language
- D3 snapshotted the removal's TARGET, but whether the player offered Remove still followed the
  selected list: launched from Watch later (no Remove, by design), selecting another list under it
  made Remove appear — and delete from Watch later. The snapshot now carries the launch list's
  editability too.
- Selecting another list under an open player (the command palette works over it) put the page into
  "Loading…", and the player was rendered only in the loaded branch — it vanished mid-playback and
  came back at its launch video. It now sits at one place in the tree whatever the page is doing.
- A removal takes the video out of the CACHED list as well as the rows: the player's progress
  checkpoint rewrote that entry before the refetch landed, handing the membership guard a list that
  still held the video — the row came back and the undo history went.
- The watched-state callback refreshed the selected list, not the launch list (D3's sibling).
- `_own_playlist`'s 404 is structured (`{"code": "playlist", "reason": "not_found"}`) and localised:
  the bare "Unknown playlist" reached the Hungarian UI in English, which also made round 1's new
  `removeFailed` string unreachable. Both Remove and Move report through `notifyActionError` now.
- The "viewer moved on under the confirm" test stepped back only once, which lands on the same video
  whether or not the removed one left the queue; it now takes the second step that tells them apart.

peter 6de2cd950d fix(ui): toasts raised while a full-screen player is open show inside it, not under its scrim
The app's Toaster lives in the content column, which is a stacking context (its `@container` implies
layout containment), so both full-screen players — portalled to <body> at the same z-index — painted
over every toast. Round 1's "a failed Remove is reported" fix was therefore still silent inside the
player: its toast sat under an 80% black, blurred scrim (elementFromPoint returned the scrim), and a
click on it closed the player.

An overlay now mounts its own `<Toaster overlay />`, and exactly one host shows the toasts: the most
recently mounted overlay, else the app's. Same component, same look — and inside the aria-modal
dialog, where a screen reader can still reach it. A click on a toast inside an overlay stays there.
Both players get one (the Plex player's also works in native fullscreen, where nothing outside the
fullscreen element is drawn). Verified on localdev: the removal failure reads above the scrim,
bottom-left, and clicking it leaves the player open.
2026-09-11 03:18:55 +02:00
peter 645d14f45d fix(plex): a subtitle track's failed load is heard and retried with a pause, and the poll asks about the right item, position and failure
- The <track>'s `error` never reached `onSubTrackError`: it does not bubble, and React 18 attaches no
  listener of its own to a <track> (measured in Chrome and jsdom — `onError` 0 calls, `onErrorCapture`
  1). Round 1's remount-and-give-up was dead code behind it. The hook now hands the player
  `onErrorCapture`, and the test fires a real non-bubbling `error` at a rendered <track>.
- Once reachable, the retry burned its whole budget within milliseconds of an outage (a remount
  fetches at once) and the give-up outlived turning subtitles off and on. Retries now wait (2 s,
  doubling), running out is reported at once, and picking the track again starts a fresh budget.
- Until the first timeupdate the poll sent `sessionK` — still 0 while the session request was out,
  and the PREVIOUS item's start after a move to the next episode. It now sends where the session was
  asked to start, and the track choice belongs to the item it was made for, so the next item is not
  asked about the old ordinal at the old position.
- A failing poll over a stale `partial` answer was silent: react-query keeps the last good data, the
  track stayed "showable", and the notice only rendered for an unmounted track. The hook now decides
  what the player says (`subNotice`), independently of whether a window is mounted.

peter 7360339039 fix(api): a non-finite number in a JSON body is refused with a 422, not a 500
The JSON parser under FastAPI accepts `Infinity`/`NaN`, and both progress checkpoints truncate the
position with `int()` — a hand-written checkpoint came back as a 500 with a traceback. Their bodies
now refuse non-finite floats, and the app's validation handler — FastAPI's own shape — echoes a
non-finite input by name: the default one failed to serialise its own error (JSON has no NaN), which
was a 500 by another route. Sibling of the subtitle routes' non-finite query parameters.

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).
2026-09-11 03:18:08 +02:00
peter d2e225666b test(playlists): let react-query's notify tick run inside act before the reopen click
The D1 regression test patched the cache and clicked at once; react-query delivers a cache write to
its observers on a setTimeout(0), so under the gate's parallel load the click could beat the page's
re-render and read the old row (748, not 830). Test-only race — a human reopen comes seconds later.
Stable across three full-suite runs; the D1 mutation still turns it red.

peter efd95fca01 fix(ui): the card's channel name is a real link too; call sites the bug hunt left untested now have tests
Deep-review R6 — the small items:

- The video card's channel name was still a <button> (pre-existing): ctrl/middle-click did nothing
  there while the title above it and the player's channel name honoured them. It renders through
  ChannelNameLink now, which grew a forwarded ref (the clamp measurement), pass-through attributes,
  a `tooltip`, and an opt-in `stopPropagation` so no click reaches the card's row.
- ChannelNameLink rendered an empty, still-tabbable <a> for a channel with no title yet (a stub first
  seen through a live search; pre-existing at this site). It falls back to the translated "Channel".
- The feed's SortKey→SortOption mapping existed twice in Feed.tsx; one `feedSortOptions` in
  feedSort.ts serves both modes (DIRECTIONLESS is module-private again).
- The backfill refresh's comment claimed a one-page cost. It refetches every loaded page of the
  grid, and that is the right price: backfilled videos are older, so they land below the head.

Tests for call sites that could be deleted with every lane green: the channel page running the
backfill refresh (knip had been blinded by the hook test's import), Feed handing the grid the live
results in the chosen key AND direction, the card using the link. Plus the alt-click arm of the shared
click predicate, and a plex filter-chip test that claimed it made no request while firing a real one.
Verified on localdev: the feed's channel names are anchors (same 14 px muted look), a plain click
opens the channel in-app. 7 mutations, each red on its assertion.

peter 060deb89d2 fix(playlists): "remove" inside the player targets the list it came from, reports failure, and keeps the cursor and focus honest
Deep-review R5 — five defects in the Remove button f76a2afb put inside the YT player:

- It removed from whichever playlist was selected by the time it was pressed, not the one the player
  was launched from; the selection can change under an open player (the command palette opens over
  it). The launch list is now part of the player snapshot, and the optimistic row removal only
  touches the list actually on screen.
- A 403/404 failed in total silence: the catch claimed the global dialog had reported it, but `req`
  deliberately leaves those to the caller. It now notifies, as moveItemTo already did (the silent
  catch predates this round; the full-screen consumer did not). New key playlists.removeFailed, HU+EN.
- It computed the next item from the cursor as it was when the button was pressed, but prev/next and
  auto-advance keep working under the confirm dialog: the viewer was thrown back onto a video they had
  moved past. It reads the live cursor, and if they moved on it just drops the item from the queue.
- The button was disabled for the confirm's lifetime, so the dialog's focus restore hit a disabled
  element and a keyboard user who cancelled was left on <body>, outside the aria-modal player. A ref
  guards the double press instead.
- Its accessible name was a bare "Remove"; it now names its object, like the row control.

The call-site wiring (step on, drop from the queue, close on the last item, leave everything alone
when the removal did not happen) finally has tests. Verified on localdev in the real YT player: a row
reopened at the 136 s it had just stored; Cancel returned focus to the Remove button; a confirmed
removal stepped 1/3 -> 1/2. 10 mutations, each red on its assertion. Scratch list and positions reset.
2026-09-11 01:28:27 +02:00
peter 4869d6c108 fix(player): the resume position reaches the playlist page and live search, not just the feed
Deep-review R4. 1630a3df wrote the YT player's stored position into the react-query cache so a
reopen could not rewind it — but only the feed actually read it back:

- Playlists renders from its own undoable copy of the list, re-seeded only when the SET of ids
  changes, so the patched position never reached it: close a video at 830 s, reopen it from the
  playlist, and it resumed at the old spot and the next checkpoint wrote that over the 830. A detail
  with the same membership now rebases its fresh rows into every snapshot, keeping order and undo
  history. (The ids-only guard is older than this round; the write that depended on it was new.)
- Live YouTube search results carry the same per-user position and open the same player, but their
  cache was never patched. It is now — patched only, never invalidated, since refetching an
  API-sourced search page spends 100 quota units.

Tests for what had none: a Playlists harness (PlayerModal stubbed to record its launch props) and a
PlayerModal harness with a fake IFrame API that records where each item is started — the latter pins
that stepping back to an item watched earlier in the same session resumes at THIS session's position.
3 mutations, each red on its assertion.

peter d20317e0f1 fix(plex): the collection page's watched toggle and Sort control survive the sort joining the query key
Deep-review R3. When 889d2acf put the sort into the collection detail's query key, two things on
the page did not follow it:

- The watched toggle's optimistic write kept the key's old spelling. setQueryData matches exactly,
  so it landed on an entry nothing reads, and its resync only invalidates the library root — the
  click succeeded server-side and changed nothing on screen (badge, icon, aria-label) until a
  reload; a second click toggled it back. One `detailKey` now serves the read and the write.
- Every sort change was a key with no data yet, so the whole page — hero, grid, and the Sort control
  with its open panel — was swapped for a spinner, and focus fell to <body>: key and direction could
  not be set in one visit. The previous page now stays on screen while the new order loads, for the
  SAME collection only (stepping to another must not show this one's hero meanwhile).

Verified on localdev (Rocky Collection): the toggle flips the poster; IMDb rating then Descending set
in one open panel, the hero never blanked, order reversed. 3 mutations, each red on its test.

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.
