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 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.

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 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 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 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.
2026-09-11 23:18:33 +02:00
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.
2026-09-11 23:08:11 +02:00
peter 785080f3da fix(plex): a Surprise card whose watched toggle failed is put back
Deep-review round 3 of bug hunt 2026-09 — the sibling of the collection page's fix (d349bc90).
Discover's toggle flips the Surprise draw too, but its resync refetches only the rails (refetching the
draw would reshuffle it under the viewer), so a refused toggle stayed flipped there. toggleWatchState
takes an optional `revert`, called on a failure only; the queryKeys comment that claimed the watched
toggle invalidates the Surprise key now says what the code does.
2026-09-11 18:05:30 +02:00
peter 76b5f7c93e fix(playlists): a failed background refetch keeps the list on screen, and the player outlives every branch
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).
- Tests for the two branches of "the player survives a change of selection" that round 2 left
  untested (a list that fails to load, no selection).
2026-09-11 18:05:19 +02:00
peter 1cfe6a7f59 fix(api): a gone row and a refused playlist action are said in the reader's language, and a failure is reported once
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.
2026-09-11 18:05:19 +02:00
peter 33fe895539 fix(ui): every full-screen overlay hosts its own toasts, above the players' controls, without re-announcing them
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.
2026-09-11 18:04:54 +02:00
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.
2026-09-11 18:04:41 +02:00
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).
2026-09-11 18:04:30 +02:00
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.
2026-09-11 03:47:36 +02:00
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.
2026-09-11 03:19:17 +02:00
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.
2026-09-11 03:19:07 +02:00
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.
2026-09-11 03:18:42 +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.
2026-09-11 01:45:53 +02:00
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.
2026-09-11 01:38:31 +02:00
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.
2026-09-11 01:19:14 +02:00
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.
2026-09-11 01:12:51 +02:00
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.
2026-09-11 01:08:27 +02:00
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 f76a2afbf1 feat(ui): the four small gaps — player delete, repeat-move, a real channel link, YT search sorting
Items 2, 4, 5 and 7 of the bug hunt, one round. They are independent, but they are all the same
kind of thing: an action that exists somewhere else in the app and is missing where you actually
want it.

**5 — the channel name in the YT player is a link again.** It was a `<button>`, so middle-click and
Ctrl/Cmd-click did nothing on a thing that looks exactly like a link (the YouTube icon beside it IS
an anchor and opens a tab). It is now a real `<a>` whose href is the same `?chan=<id>` URL
`openChannel` pushes, with a plain left click still taking the in-app path — that path does more
than navigate, since the player must close and reclaim its own Back-to-close history entry first.
The "is this click ours or the browser's" test is now ONE predicate (`isPlainLeftClick`), which
VideoCard's card link also uses, so a second such link cannot forget the middle-click arm.

**2 — "Remove" from inside the player.** The parent owns the removal (the SAME `removeItem` the row
menu and the inline ✕ use: one confirm, one optimistic update, one undo-stack rebase), and the
player owns what happens next, because it is the only side that knows which item is playing — its
launch queue is frozen at mount. It drops the item, plays what followed, and closes when the list
runs out. That forced a real fix in Playlists: the player's mount was derived from `shown` every
render, so anything that dropped the launch row yanked the player off the screen mid-playback. That
was a latent edge (change the view and it happens) and the normal case for this feature. The parent
now snapshots what it launched with, and only onClose takes the player down.

**4 — "Move to <the last list you moved to>".** The submenu is two levels deep and moving a run of
videos into the same list is the shape this gets used in. The remembered id is a per-account pref;
the row is derived from `moveTargets`, which already excludes the list you are looking at, so it
cannot offer a move to where the video already is. Remembered only on a SUCCESSFUL move — a
shortcut to a move that failed is a shortcut to failing again. Absent, not disabled, when there is
nothing to repeat: there is nothing to explain.

**7 — the live-YouTube results can be sorted.** Client-side, over the page already loaded. Not a
new `order=` param, and this is the decision worth recording: the owner's case is "even one page of
results", i.e. reorder what is on screen; a re-query would REPLACE the results, which is not what
"sort these" means; and the zero-quota scrape source has no order parameter at all, so a
server-side control would silently do nothing (or quietly cost 100 quota units) depending on which
source served the page. Only keys a search hit carries are offered — `subscribers`/`priority`
describe a subscription, which a search hit is not, and `shuffle` on a ranked list is noise. Its
own pref, so sorting a search page never re-sorts the library behind it.

Verified in the browser on localdev against the real account: the channel name renders as
`<a href="…&chan=…">` and a ctrl-click / middle-click is left to the browser while a plain click
still opens the channel in-app; removing from the player stepped 1/3 → 1/2 onto the next video and
closed on the last one; the row menu grew "Move to “…”" only after a move and only on a list that
is not the target; and the results sort reordered by views 41.7M → 29.8M → 24.2M → 15.8M. (The
pane's own ctrl-click arrives without the modifier — a harness limit, so the modifier cases were
driven as real MouseEvents.) Scratch playlists and the touched prefs were cleaned up afterwards.

22 vitest, mutation-checked against 14 mutations (no href at all · href without the rest of the
query · every click hijacked in-app · the middle-click arm dropped from the predicate · plain click
no longer in-app · always jumping to the top of the list · the removed item left in the queue · no
clamp when the last item goes · an empty queue not reported as "nothing left" · sort-then-reverse
flipping ties · unknown values first · titles compared numerically · shuffle offered on search
results · direction ignored) — each red on exactly the test that names it. Item 4 has no test of
its own: its rule is enforced by construction, not by a check.

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 782362b808 fix(channels): the video grid follows a running backfill instead of freezing until F5
"Get full history" on a channel page left the list on the cards the channel already had. The
count above it climbed into the thousands, the grid did not move, and only a browser F5 brought
the rest in.

The mechanism: the backfill runs in a BackgroundTask, so the PATCH that starts it returns before
a single row is written — and the mutation invalidates `qk.feed()` on that RESPONSE, which just
refetches the OLD catalogue. Nothing afterwards refetches it: the feed's infinite query has no
interval, and the app-wide defaults are `staleTime: 30s` + `refetchOnWindowFocus: false`. The job
emits no event either (the realtime layer only carries messages today), so the channel detail's
4s live poll is the only thing in the app that sees the job progress — and it refreshed only
`qk.channel`.

So the poll now drives the grid too: on a tick where the stored count moved (or the backfill
finished), it invalidates `qk.feed()` and the `qk.feedSummary()` behind the count pill. The window
is the poll's own (`deep_requested && !backfill_done` on the previous reading), so a detail
refetch caused by some other mutation — each of which invalidates the feed itself — cannot come
through here twice.

Measured on localdev against the real account, same instrument, `document.visibilityState`
forced visible (the poll deliberately pauses on a hidden tab, and a headless pane reads hidden —
without that the first measurement was about the harness, not the fix):

  before — CASCADA 19 -> 176 stored: the header updated live to "162 normal", the grid and its
           count pill sat on "5 items" for 50s.
  after  — fern 54 -> 139 stored: "54 items" -> "139 items" by ~12s, no reload.

6 vitest, mutation-checked against six mutations (no invalidation at all; grid only, count pill
forgotten; predicate ignored; no channel-identity guard; completion with an unchanged count
dropped; poll-window guard dropped) — each one 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 1630a3df3c fix(player): the YT progress checkpoint reaches the cache, so a reopen cannot rewind it
The player checkpointed every 5s and the server stored it, but nothing wrote the new
position back into react-query: the close path only marked qk.feed() stale with
refetchType "none", and nothing refetches the feed until it remounts (staleTime 30s,
refetchOnWindowFocus off). So the resume read the position the cache had been FETCHED
with, and the next checkpoint then persisted that older value over the newer one.

Measured on localdev: played to 830s, closed (server had 830), reopened the same card
without a reload -> the row was back to 751s. 79 seconds of progress destroyed by a
reopen, and the card's progress bar never moved either.

The Plex player already solved this for its detail query, with a comment describing the
identical failure; this is the feed-side twin that was missed in that sweep. patchCachedProgress
writes the position the SERVER stored (the endpoint clears trivially-early and near-finished
checkpoints to 0, so mirroring our own reading would disagree with the row) into every cached
feed page and playlist detail, keeping array identity where nothing changed. A session map
covers the second half: the launch queue is frozen at mount, so stepping next->prev back to an
item played earlier in the same session resumed from that snapshot.

Verified in the browser: 811 -> close 816 -> reopen 825, and the card now shows Continue/Restart.

peter d832bb19ce fix(e24): review round 4 — a test that pinned nothing, and prose still ahead of the code
Round 4 reviewed round 3's commit. Nothing in production behaviour was wrong; what was wrong
was the round's own test and its comments, which is the failure class this loop keeps
finding.

- The new NavigationProvider case named after the `&& !channelViewRef.current` clause never
  reached it. With storage cleared and a bare URL the provider lands on "home" (E24's own
  default), not "feed", so asking for "feed" was an ordinary page change and the guard's
  first conjunct short-circuited. Deleting the clause left all 828 tests green — a dead nav
  control (the rail's own module stops closing an open channel page) with no red anywhere.
  The test now asserts the precondition and calls `setPage` with the page that IS current.
- Both new Home cases rejected a promise and then asserted after one fixed macrotask.
  React-query notifies through `notifyManager`'s own `setTimeout(0)`, registered after any
  timer the test schedules, so the assertion raced it; two reviewers measured intermittent
  reds. They poll for a signal that the rejection LANDED instead — the reroll button
  releasing, which is also the honest one for the empty-answer case, where the empty state is
  already on screen while the press is in flight and asserting it early would pass either way.
- `buryUnder`'s comment still opened with "one rule for both entry points" ten lines above the
  paragraph saying the rule is complete only for one of them, listed the non-reporting palette
  rows without `openChannel` — which has its own `replaceState` no-push branch and is reached
  from PlayerModal too — and pointed at a ROADMAP.md this repository does not contain.
- `history.dom.test.ts`'s header claimed its layers close by genuine Backs only, which two of
  its own tests contradict; and `CommandPalette.ordering.dom.test.tsx` still claimed to be
  "the only assertion in the suite" doing what the file corrected in round 3 also does. Round
  3's message said that pair was handled and only one side had been.

The provider test was re-mutation-checked (dropping the clause now goes red), and both
hardened Home tests still go red against their own reverts. Seven consecutive full runs green.

peter 59efc8f2e8 fix(e24): review round 3 — the holes round 2's own fixes left
Round 3 reviewed the round-2 commit across six dimensions. Fifteen findings, five survived
three adversarial refuters each; three died on 2+ refutations (a keyboard-focus claim that
is a property of `ui/Button` at all six of its `loading` call sites, a contract-test
false-pass that needs a deliberate revert plus a self-incriminating comment, and a
MAX_EXCLUDE coupling whose slice is unreachable from the real client).

- `rerolling` was still wrong for a FAILED press. `data === undefined` is true forever for a
  key whose request failed (`retry: false`), so the next unrelated mutation re-disabled the
  reroll button — the same defect round 2 reported, one branch over. `!isFetched` is the
  flag that remembers a key settled; `!isError` would not have worked, because query-core
  resets a data-less query to "pending" for the duration of a refetch, hiding the error
  exactly when it matters.
- The hero fallback used `??`, which cannot tell "this budget's last pick resolved to NO
  hero" from "nothing remembered". So a press that failed after an empty one resurrected the
  card the page had already excluded as seen and just said it had nothing beyond. The tagged
  slot is now authoritative for its own budget.
- `setPage`'s boolean — the input the whole burial rule reads — was asserted by nothing.
  The type fences the SHAPE, so deleting a `return` fails tsc, but swapping the two values
  passed typecheck and all 822 tests. NavigationProvider gets its first render test, on the
  value AND on the effects the early return skips.
- `closeThenNavigate`'s door into `buryUnder` was equally unpinned: reverting that one call
  site to the old unconditional burial left the suite green. It has the mirror case now.
- The comment claiming one rule serves both entry points was overstated. `buryUnder` fails
  OPEN, and `CommandItem.run` is typed `() => void`, so only the palette's bare
  `() => setPage(page)` rows forward the boolean at all. Nothing regressed — that path buried
  unconditionally before — but the prose said more than the code does, so it now says what is
  true and points at the deferred fix. Same for a "the only assertion in the suite" claim
  that the file it cites as precedent also makes.

Every new test mutation-checked red for the right reason, both edges where there are two.

peter e4ffd59ca7 fix(e24): review round 2 — a buried history entry, a stale hero, and a spinner that was not ours
Nine of the round's ten surviving findings. The tenth (a failed shelf reorder leaving an
order the server rejected on screen) is on ROADMAP.md: its obvious remedy reintroduces the
overlapping-move defect the code already documents, so it wants a design, not a review edit.

- `navigateOverOverlays` buried the live overlay entries before knowing whether the
  navigation pushed one. `setPage` no-ops when the page is already current and Home is the
  default landing page, so Shift+W over a player ON Home marked its entry buried under a
  push that never happened: the unmount consumed the mark instead of reclaiming the entry,
  and the next browser Back was a press that did nothing. `setPage` now reports whether it
  navigated, and one `buryUnder` rule serves both entry points — `closeThenNavigate` takes
  the same no-op navigation from a palette command for the page you are already on.
- The hero could answer a new time budget with the previous one's pick. The chip row resets
  seed/seen/press but cannot reset an answer that already resolved, and `keepPreviousData`
  chained through the disabled seed-0 query — so a reroll under "10 perc" showed the film
  picked for "Bármennyi" while it loaded, and kept it if the request failed. `lastPick` now
  carries the server's own budget echo, and the placeholder is scoped to the budget.
- The reroll button spun and swallowed clicks after mark-watched, bookmark, pin and shelf
  moves: the pick key sits under the invalidated `discover` prefix on purpose, so raw
  `isFetching` was true for background refetches. It now means "a press of mine is
  outstanding" — which still covers the first press, where there is no placeholder.
- Failed writes on Home toasted the page's LOAD-failure string over a fully loaded page;
  they get their own key (HU+EN). The empty-state reroll had no `loading`, so the press was
  unacknowledged and a second click skipped a tier. `danger` moved into the shared unpin row
  so the same command is not red on the shelf and neutral in the rail below it.
- Two comments claimed things the code does not do: the `exclude` cap guards no "unbounded
  scan" (it never reaches SQL), and the route test that named the cap sends three keys.

Tests: the burial rule gets its own file (it is the one assertion that lets a reconcile
issue a real programmatic back()); App's keymap wiring gets a source contract, because
dropping it left all 818 tests green; `add_pin`'s IntegrityError arm was reached by nothing.
Every new test mutation-checked red, both edges where the predicate has two.

peter 3709b71a94 fix(e24): the review's low findings — dead constants, honest labels, a 500 that should be a 404
`add_pin`'s IntegrityError handler assumed the unique constraint was the only way in and
re-raised otherwise, so a target row pruned between `resolve_ref` confirming it and the
INSERT (a Plex sync dropping a removed item) tripped the FK and handed the user a 500.
Semantically that is the same "no such thing" the pre-check already returns. Untested: the
race needs two concurrent transactions.

The five per-kind unique constraints had no test at all — the route's own dedupe returns
before reaching the DB, and the migration drift check filters constraint diffs out as noise,
so they could go missing with every lane green.

Frontend, all from the same review: the shelf's unpin row is now `danger` like every other
destructive row in the app; the hero's artwork button says what it will actually do and
names the item instead of always announcing "Play"; the empty-budget message offers a reroll
rather than `StateMessage`'s "Retry", which promised a re-run of something that had not
failed; `setState` and the watch-later toggle catch their rejections instead of leaving an
unhandled promise and a click that silently does nothing.

`StateMessage` gained a `compact` rung, which retires the frontend's only two `!important`
overrides — they existed to beat the primitive's own padding from the call site, and were
the copyable idiom for the next surface that wanted a compact empty state.

Dead vocabulary removed or made load-bearing: `DISCOVER_BUDGETS` was exported, re-exported
and consumed by nothing while `Home.tsx` re-typed the same four bands (a `readonly
DiscoverBudget[]` accepts any subset, so a fifth band would have typechecked green and
rendered no chip); `PIN_KINDS`' value export had no consumer at all; `useComfortPin` no
longer publishes `pinIdOf`/`toggle`, which nothing outside the module calls.

Three comments corrected against the code they describe: a pointer to a `resolve.py` that
was never written, the file header's claim that Home defines no card component of its own,
and the `seen` window still quoting the 8 that was measured and abandoned for 32.

The rest of the review's survivors are logged on ROADMAP.md under "Deferred — E24 epic-end
deep-review (2026-09-08)" — the ones whose dissent was substantive, and the ones whose fix
is wider than the finding.
2026-09-08 03:23:59 +02:00
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.
