Deep-review round 1 on feature/plex-playback-class-filter:
- Sticky watermark (medium): _apply_item reset the bit-depth probe watermark
only on a codec-string change, so a same-codec re-encode (8-bit->10-bit HEVC)
kept a stale video_bit_depth/transcode_hw forever (the backfill only re-probes
media_probed_at IS NULL rows). Also reset when the Plex Part key changes (the
file was replaced), not just the codec.
- i18n parity (medium): the HU playback-class labels were mixed-language (only
'direct' translated). Translated remux/transcode_hw/transcode_sw and the
tooltips consistently to Hungarian (Kozvetlen streameles / Atkodolas).
- Layering (low): _PLAYBACK_CLASSES was module-private yet imported across into
routes.plex.browse; renamed to public PLAYBACK_CLASSES (it is the shared
source of truth for facet order + zero-fill).
- a11y (low): the browse-card playback-class dot conveyed meaning only via a
mouse-hover title; added role=img + aria-label so SR/touch users get the class.
- tests: the NULL/unprobed transcode_hw -> SW fold (filter + facet), facet
self-exclusion under an active playable filter, the migration codec-set ==
HW_DECODABLE_CODECS drift guard, the probe-batch bound + oldest-first order,
the transient probe-failure retry path, and the same-codec re-encode re-probe.
Backend gate green (ruff + full pytest); FE gate green (tsc/lint/knip/prettier/
vitest). NOTE: the facet-vs-runtime disagreement for 10-bit HEVC (C1) is the
known merge-order constraint — this branch's runtime is codec-only; the facet
becomes truthful once BUG1/tonemap's bit-depth-aware routing lands with it. Left
as a sequencing constraint, not code-changed here.
Adds a movie-scoped "Playback" filter to the Plex feed so a user can isolate items by how
they play — the groundwork for collecting HW-transcodable (or no-transcode) versions.
Four classes derived from the stored `playable` + a new `transcode_hw` facet:
- Direct Play (direct), Direct Stream (remux)
- Transcode · HW — playable=transcode AND the iGPU can hardware-transcode it
- Transcode · SW — playable=transcode, software libx264 only
The HW/SW split is precise, not codec-only: a 10-bit/HDR HEVC is HW-decodable yet breaks the
VAAPI nv12 pipeline (the same case plex/stream special-cases), so it must count as SW.
Backend:
- New PlexItem columns (migration 0077): transcode_hw, video_bit_depth, media_probed_at.
Migration backfills transcode_hw codec-only so the filter works immediately.
- `plex.sync.transcode_hw_capable` is the single classifier; the HW-decodable codec set moves
to sync as `HW_DECODABLE_CODECS` and plex.stream imports it, so the catalog facet and the
runtime encoder choice can't disagree by codec.
- Bit-depth backfill (`_probe_media_batch`, wired into sync): probes only HW-decodable transcode
items' video Stream for bit-depth + HDR and refines a 10-bit/HDR HEVC to software. Bounded
per run, watermarked by media_probed_at. A codec change resets the watermark (stale probe).
- Filter + self-excluded facet on a shared `playback_class_expr` CASE (movie-leg only — a show
is an aggregate with no single class). transcode_hw threaded onto the feed/detail/card JSON.
Frontend:
- Multi-select "Playback" Combobox in the sidebar (movie scope, facet-empty drop-out), active
chips, 4-way corner-dot badge (green/blue/amber/red) + tooltip, and an info-page playback chip
with a codec · bit-depth subtitle. New `bg-info` (blue) token, i18n HU/EN parity.
- Fix a regression where the card's playback dot lost its hover tooltip: the full-card reveal
overlay swallowed the cursor; the dot now sits above it (z-20).
Gate: backend full lane + frontend typecheck/lint/knip/prettier/vitest all green. Browser-UAT'd
on localdev (filter narrows to the SW set, facet counts, badge colour + tooltip, info chip).
User-reported issues after the E5 build:
- useCrossfadeBackdrop: the static branch (one image / crossfade off /
reduced motion) painted #root but returned NO cleanup, so the backdrop
persisted after leaving the page (e.g. switching modules). Every painted
branch now returns clear() so unmount always resets the default backdrop.
- scheduler: give the tmdb_enrich job a proper label + description (was the
raw "tmdb_enrich" id) in EN/HU.
- CastStrip: cap crew names to ONE line (truncate) so the row of circular
photos sits on one baseline instead of going wavy on 2-line names.
- PlexInfo: lay Details / Keywords / Crew out as side-by-side boxes
(items-start grid) instead of full-width stacked panels with dead space;
narrower Crew grid for the boxed width; each panel independently hideable
from the customize menu (new Details/Keywords/Crew toggles). Tighter
vertical spacing.
- MultiSelectChips: reshape the trigger from a "+Add" button into an
Overseerr-style combi input — removable chips inside a typeable field that
filters the checklist, opening on focus (backspace removes the last chip).
- Discover / person rails: reduce the vertical gap between rails.
The poster card (grid + person page) gets the Seerr-style hover: on hover a
bottom scrim slides up with the title, a "year · runtime · ★rating" meta line,
and a 3-line synopsis — the info you'd otherwise click through for — plus a
less-flat play ring (radial-gradient + ring shadow) and a top-right quick-action
cluster (Info + watched-toggle, revealed on hover / always on touch). Rest-state
badges (season / type tag) yield to the scrim on hover; the playable-cost tint
stays. (§1 A + C from the enrichment study.)
Backend (the data the scrim needs, mirroring S1's `art`): the grid
(browse.unified_library) now emits a lang-coalesced, truncated `summary` (new
query.summary_col) + the Plex `rating`; movie_card/show_card do the same (EN) for
the detail/related/person cards. PlexCard.rating type added (summary already
existed for episodes).
Gate: tsc x3 / eslint / prettier / knip / vitest 326 green; ruff green; backend
lane full suite green. Self-E2E on the live dev server (rebuilt on this branch,
S2-enriched): the grid serves rating+summary (Shawshank 9.3, Godfather 9.2, real
synopses) and the card renders the play ring + scrim (The Expanse: ring, synopsis,
★8.1) — verified via the DOM (the pane wouldn't composite for a screenshot).
Wave 5a building blocks under the Seerr-inspired Plex enrichment (E5).
Carousel (frontend/src/components/Carousel.tsx): the one horizontal-rail
component, replacing the hand-rolled `flex overflow-x-auto` strips and the
home of the future Plex-Discover rows. Edge-fade mask, hover/focus scroll
buttons that appear only on the clipped side (useHScroll — the X-axis twin
of useScrollFade, same watch-the-children discipline), native scrollbar
hidden behind .no-scrollbar, reduced-motion-aware paging. First consumers:
CastStrip + RelatedStrip now scroll inside it (dedup + free affordances).
New i18n: common.seeAll / scrollLeft / scrollRight (en+hu).
Card-art serializer (backend/app/plex/cards.py): movie_card + show_card now
emit `art` (the wide backdrop, /api/plex/image/{rk}?variant=art) so rails and
the crossfading hero get a landscape image with no per-item fetch — gated on
art_key so an art-less item stays null and falls back to the poster. FE type
PlexCard.art?.
Tests: Carousel.dom.test (children/header/see-all, clipped-edge buttons +
paging), test_plex_cards (art present/absent by art_key). Added a
ResizeObserver stub to PlexPersonView.dom.test (it renders CastStrip, now a
Carousel consumer).
Gate: tsc x3 / eslint / prettier / knip / vitest 324 green; ruff green;
backend test lane (docker-compose.test.yml) green on the plex card tests.
Resolves the 5 /code-review high findings on this branch:
- a11y sweep: extend aria-label to the remaining icon-only Plex card buttons the
first pass missed — PlexPosterCard Info, SeasonCard watched-toggle + add-season
(EpisodeCard already had them). "Fix a principle everywhere, in one sweep."
- new shared lib/parseId.ts `parsePositiveIntId`, used by BOTH readSelectedId
(now guarding the stored ?pl fallback the same as the URL — was unguarded) and
plexSubUrl's ?v=playlist decode; removes the hand-duplicated guard.
- PAGE_KEY exported from navigationInit and imported by NavigationProvider (was
defined in both).
- hoist a `watchedLabel` const per card so title + aria-label can't drift.
+8 tests (parseId unit + guarded-stored ?pl); full FE gate green (tsc/eslint/
prettier/knip, 317 vitest).
The hover watched-toggle on Plex movie/episode cards is icon-only (WatchedIcon,
no text), so it carried a `title` but no accessible name for screen readers —
and the empty-Circle unwatched glyph could read like a radio. Mirror the title
into `aria-label` (the Modal close-button idiom) so the control announces its
action. The PlexInfo watched buttons already have visible text labels, so they
need nothing.
FE gate green (tsc/eslint/prettier/knip, 309 vitest).
Deep-review (6 dimensions, 3-verifier adversarial pass) surfaced 7 findings, all
verified; fixed here.
- NavigationProvider + history.ts (medium, correctness): the popstate handlers
restored the open channel / Plex sub-view from history.state ONLY, but a fresh
?chan / ?v bookmark lives in the URL with no marker in state — so any overlay's
programmatic history.back() (closing a modal/player) silently closed the
bookmarked channel or collapsed the sub-view to the grid. Give onPop the same
URL fallback the initializers already use (history.ts extracts a shared readView
so seed and popstate can't diverge again).
- plexCards SeasonCard (medium, a11y): the "In progress" season badge was a
reveal-idle swap-badge → display:none on touch, and a season has no progress bar,
so an in-progress season was indistinguishable from unwatched on touch. Moved it
to the top-left (the toggle owns top-right) and made it always visible.
- plexCards watched toggle (low, a11y / WCAG 1.4.1): watched state was color-only
on touch (green vs white CheckCircle2). New WatchedIcon distinguishes by SHAPE —
CheckCircle2 (watched) vs an empty Circle (not) — used by all three card toggles.
- Modal.tsx (low, a11y): the focus trap leaked on Shift+Tab when focus rested on
the panel container itself (Node.contains(self) is true, so the pull-back branch
never ran). Guard now also checks `active === panel`.
- index.css (low, a11y): .reveal-idle faded only on .group:hover though .reveal is
revealed on hover AND focus-within → the badge overlapped the control on keyboard
focus. Added the focus-within fade.
- PlexBrowse.tsx (low, correctness): the ?v=playlist decoder accepted a non-integer
id (Number.isFinite); tightened to Number.isInteger(n) && n > 0, matching the ?pl
guard.
Gate green (tsc, knip, lint 0-err, 247 vitest). Self-E2E (localdev): ?v=show and
?chan bookmarks survive a modal open+close (were collapsing/closing before); Modal
Shift+Tab from the panel stays inside; in-progress season badge visible on touch;
watched toggle shows an empty-circle-vs-check shape difference; 0 console errors.
Applies the /code-review high findings on the E4 branch:
- usePref: flush the pending debounced server write on unmount instead of
clearing it, so the last change isn't lost (and can't later be overwritten by
the stale server value via the adopt effect). [correctness]
- PlaylistsProvider.readSelectedId: accept ?pl only when it's a positive integer
— "?pl=" gave Number("")===0 (finite) and "?pl=1.5" a fractional id, both of
which selected a non-existent playlist. [correctness]
- usePref: extract mergePrefsCache() so useSavePref and usePref.set share the
one me-cache merge shape instead of duplicating it. [reuse]
- New lib/useUrlMirror: the shared replaceState(urlWithParams(...)) mirror
effect, so FeedFiltersProvider and PlaylistsProvider stop hand-rolling the
identical block (keyed on the serialized delta so it only fires on change).
[reuse]
- plexCards: swapBadgeReveal() helper for the repeated
reveal-idle/group-hover:opacity-0 swap-badge ternary. [simplification]
Gate green (tsc, knip, lint 0-err, 247 vitest). Self-E2E (localdev): feed filter
mirrors to ?show and clears on leaving the feed / re-mirrors on return via
useUrlMirror; ?pl= (empty) and ?pl=abc no longer select a bogus playlist (fall
back to the stored selection); Plex reveal-idle badges still display:none on
touch after the helper refactor; 0 console errors.
UX-7 — hover-only card actions were `opacity-0 group-hover:opacity-100`: fine on
a mouse, but invisible AND still tappable on a touch device (no hover). New
`.reveal` primitive (index.css) gates the hide on `@media (hover: hover)`, so a
touch device keeps the control visible; its partner `.reveal-idle` is the idle
badge a control replaces (watched/in-progress pill under the watched-toggle),
faded on hover and dropped on touch so the two don't collide at the same corner.
Migrated the true controls — feed card action toolbar (VideoCard), Plex poster
card watched-toggle/info/add across all card variants + their swap badges
(plexCards), message pop-out (Messages), edit-interval pencil (Scheduler), and
saved-view star/rename/delete (SavedViewsWidget). Pure play-scrim overlays (the
whole card is the tap target) stay hover-only by design.
FE-9 — Modal.tsx had aria-modal but no focus management. Adds: a Tab/Shift+Tab
focus trap (topmost layer only, wraps at the edges and pulls escaped focus back);
initial focus into the dialog unless an autoFocus child already placed it; focus
restore to the trigger on close (captured in a useState initializer during render,
before commit runs autoFocus and moves activeElement inside); and aria-labelledby
wiring the dialog to its title.
Gate green (tsc, knip, lint 0-err, 247 vitest). Self-E2E (localdev): FE-9 trap
both directions + pull-back + Escape-restore-to-trigger + aria-labelledby verified;
UX-7 feed toolbar opacity 0 on desktop / 1 under mobile (hover:none) emulation,
Plex reveal buttons opacity 1 + reveal-idle badges display:none on touch.
