vicrodh 1f636679d5 fix(qt): "Play all next" enqueues the artist instead of replacing the queue
The artist ⋯ menu offers "Play all next", "Add all to queue" and "Shuffle
all". The first was wired to `playArtistTop(false)` — which the bridge's own
doc calls "Play all": it REPLACES the queue and starts playing. There is no
plain "Play all" row in that menu, so there was no way to get the intended
behaviour, and asking to queue an artist next wiped whatever was queued.

The invokable takes a mode now and both rows route through the shared
insertion funnel: "next" inserts at the cursor, "queue" appends. That is
what the reference does (`enqueue_artist_top_selected(.., next: true)`) and
what `playback_qt::enqueue_artist_top_mode` was written for — it had no
caller at all, which is how the miswiring survived.

vicrodh dc2496e5c0 feat(qt): award pages, reachable from the album sidebar and from each other
Ports the Slint/Tauri award pair: the landing (gold laurel hero, magazine
line, follow heart, "Acclaimed Releases" with its count and See All, the
preview grid and the "Other awards" rail) and the paginated listing with
its client-side search. Routes "award" and "awardalbums", the label pair's
shape — one controller for both, since they share the hero, the follow
state and the identity.

The three rules from the Tauri review are in the module header because they
are the ones a re-implementation gets wrong: the grid is ALWAYS
/award/getAlbums (/award/page is user-scoped and may omit releases, so it
feeds the hero and nothing else); the favorite split is plural-read,
singular-write, because the backend derives `award_ids` from the write
kind; and getAlbums has no has_more, its `total` is a hint, so the only
sound predicate is `total > loaded`.

The album sidebar's AWARDS cards navigate now — with an id directly, and by
NAME through the resolver when Qobuz omits it, which it does. They were
also reading `album.awards` when the field lives on `album.header`, so the
block had rendered EMPTY for every album since it was written: an empty
Repeater draws nothing and reports nothing, and the sidebar's own gate
counted the same empty list. The LABEL card beside it had a "no label view
yet" note and no handler, years after the label view landed.

Beyond the reference: an all-awards dropdown pinned to the page's top-right,
so any award is reachable without first finding an album that won it. It
costs nothing new — the /award/explore crawl already existed to resolve
names to ids.

The award icon was lucide's MICROPHONE under the wrong filename. Search had
routed around it with `crown` and left a note; kiosk was missed and drew a
mic for "Most popular". The asset is the laurel the other two frontends use,
and kiosk now asks for the crown it wanted.

vicrodh 41c1b50d61 feat(qt): offline cache manager, and stamp the album identity on cached tracks
The last missing Settings surface: the OFFLINE CACHE group (Open manager /
Open folder / Clear all) and the manager view behind it — stats bar with
the GB limit, sort and failed-only toolbar, A-Z artist rail, album+track
rows with per-row re-download and remove. The engine was already here; what
was missing were four actions (remove_album, redownload_track, open_folder,
clear_all), the rollup and the view.

Two bugs the owner's smoke exposed, both older than this view:

ALBUM IDENTITY WAS BEING LOST ON EVERY ALBUM DOWNLOAD. A Track inside an
/album/get payload carries no nested album object, and `track_cache_info`
read exactly that, so `cache_album` wrote `album = NULL, album_id = NULL`
for every track it queued. Measured on a real index: 34 of 46 rows, three
complete albums. Not cosmetic — `album_id` is the key `remove_album`,
`redownload_album` and the downloaded-album registry look rows up by, so
those albums could not be removed, refreshed or recognised as downloaded.
The album document now stamps id and title onto every track that lacks its
own. The reference has the identical bug.

AND THE ROLLUP MIXED ARTISTS. Every row without an album_id collapsed into
one "__singles__" bucket titled from the first track and credited to its
artist, so three albums by three artists rendered as ONE album header while
two of the artists vanished from the rail. The key is a ladder now: album
id, else (artist, title), else a per-ARTIST singles bucket — two artists
can no longer meet in one group even with the broken data. Rows already on
disk recover their title from library.db, which does know it, so an
existing cache reads correctly without re-downloading.

Deltas from the reference, both because Qt is not Slint: covers are paths
(slint::Image is not Send, which is why it pre-decodes; Qt has no such
constraint) and selection is QML-local, this port's convention, which keeps
the document a pure function of the DB so a finishing download cannot fight
the user's checkboxes.

Clear-all confirms first — the reference fires straight from the glyph, and
undoing this one means re-downloading the whole cache.

vicrodh 9899ad6b09 feat(qt): open the playlist importer from the Playlist Manager toolbar
The importer had exactly two doors, both inside the sidebar's playlist
popup, so the one view whose job is managing playlists could not reach it.

Placed before "New folder": that slot disappears in flat mode and a Row
skips invisible children, so a button after it would slide sideways every
time the mode toggles. No offline gate — the modal recomputes its own and
shows a disabled confirm with the reason, which beats a toolbar button
that vanishes when the network drops.

No new msgids: "Import" is already in all eight catalogs.

vicrodh 16a25bbbe6 fix(qt): pin the Local Library tracks scrollbar to the view edge
The bar sat inside the tab's 32px content inset AND carried its own 4px
margin, leaving it 36px from the window with an empty channel beside it.
It now cancels the inset; the rows keep theirs.

The "By name" arm is untouched: there the alpha strip owns the right edge
and 22px is what clears it. The inset is a named property now because the
scrollbar has to cancel it — written twice, moving one silently misaligns
the other.

vicrodh 13f1b106dc fix(qt): keep the Local Library select button clear of the search box
The expandable search keeps a 30px footprint and grows its inner field
LEFT (QbzLineEdit.qml, `x: root.width - width`), so anything positioned
before it in the row is covered while the search is open and cannot be
clicked. On the Tracks tab the multi-select button led the row and was
exactly that.

Moved to the end of the group — the slot the Albums tab already puts it
in, so the two tabs agree as well.

Swept the other nine expandable searches: in all of them the field is
already the first child of its row, and the tree rail's box width is
computed to stop at the third button. Tracks was the only case.

vicrodh 7d98ad044f feat(purchases): the Qt frontend — list, album detail, routing and gating
Two screens, a controller and a bridge. `QbzPurchases` publishes one JSON
document per screen plus a revision counter, so QML re-parses even when the text
is byte-identical.

- The list: two tabs with per-type counters, a server-side search on a 300 ms
  debounce, and a toolbar that DIFFERS by tab — Albums gets group, sort,
  direction, two filters and grid/list; Tracks gets group and the filters only.
  Building the Albums toolbar on both would have invented two controls.
- The detail: a format dropdown whose selection re-scopes every downloaded mark,
  the progress section and Add-to-Library together; a determinate bar counted in
  TRACKS, never bytes; goodies as an album-level action counted separately.
- The album download is the frontend loop, not the Rust command the reference
  registered and never called. Sequential, concurrency 1, cancellable, and a
  failed track does not abort the album.
- Both prefs are read at runtime, not merely written. `show_purchases` is the
  master gate and `nav_tb_purchases` only relocates the entry to the title bar;
  both default false, so Purchases still ships hidden.
- Scanned local rows keep their raw `qobuz_purchase` source so the gold badge
  survives in list mode as well as grid, while still classifying under the
  Offline source filter. Remote feed rows deliberately stay `qobuz`: stamping
  them would badge every purchase the user merely OWNS as locally downloaded.

Defects fixed after the screens were written, none of which any test could have
caught:

- `QbzPurchases.boot()` was called nowhere. Without the Qt-thread hop every
  publish is a silent no-op, so both screens would have stayed permanently empty
  with nothing logged. The cause was an ownership gap rather than the code:
  `Main.qml` belonged to no lane because the plan listed the files each lane
  CREATES rather than the files it TOUCHES, and "belongs to nobody" is
  indistinguishable from "done" until something runs.
- A second download of the same album nested inside the first. The store rewrites
  its destination to the album subfolder after the first successful track so that
  Add-to-Library adds the album rather than the whole music root, and the download
  planner read that value first — producing `.../Album [q]/Artist/Album [q]/...`,
  one level deeper each time. The picked ROOT and the resolved ALBUM FOLDER are
  now separate fields with names that cannot be confused, with a regression test.
- A tab counter could stick at zero forever with its list plainly full: the two
  ids calls each swallow their error, and the reference's backfill from the list
  response was missing.
- Cancelling made the whole progress block vanish instead of showing the
  cancelled state, whose msgid was already translated in all eight catalogs.
- Add-to-Library re-walked the entire library when the folder id it needed was
  already in hand.
- A live language switch and a logout left the previous state behind.

Deliberate divergences from the contract, each recorded with its reason: the page
header is a plain `fontSection` title with no icon tile, because nothing else in
this application announces itself over a large coloured square; purchase download
status travels inside the album document rather than on the shared cache channel,
which is keyed by track id alone and would let the two features overwrite each
other on the same row.

Gate: release build clean, QML audits 278 files / 37 bridges, `cargo test -p
qbz-qt` 398 passing, offscreen smoke green with zero QML complaints.

Not verified, and cannot be from here: every populated screen. This account owns
nothing, so only the empty states have ever rendered.

vicrodh 8bd02e35d3 feat(qt): custom-theme editor, artist portrait, playlist rail, About/What's New and diagnostics
Five surfaces the Qt frontend was missing, landed together because they share
five wiring files (build.rs, main.rs, shell_bridge.rs, AppShell.qml,
HeaderBar.qml) and splitting them would produce commits that do not build.

ARTIST PAGE
- The Playlists section used a hand-rolled Rectangle delegate: a MouseArea with
  no onClicked, and a RoundedImage with no fit:, so the default crop blew an
  800x380 playlist banner up inside a 200x200 box and showed the middle 47% at
  2.1x. Replaced by the real cards/PlaylistCard.qml — already live on five other
  surfaces — mounted in a new views/PlaylistRail.qml modelled on SectionRail.
  ArtistPlaylist publishes the five roles the card reads.
- The portrait gains what the album cover has: the right-click menu the Slint
  reference already has (Add/Change/Remove image, Open in browser, Save as…) and
  the lightbox this port invented for albums and playlists. Custom images are
  keyed by artist NAME into the same custom_artwork.json the Slint build writes,
  so they round-trip between the two.
- CoverLightbox is now aspect-aware. It forced a square box on the premise that
  covers are square; artist portraits are not (1080x720 measured in the cache).
- Removing an override invalidates the pipeline's resolved path for that url:
  artwork_qt::cached_path consults the override FIRST, so coverMap held the
  custom file and the header kept showing the picture the user had just deleted.
- artwork_qt::local_path is the inverse of file_url. trim_start_matches("file://")
  is not: it leaves the percent-escapes in place, so any path holding % # or ?
  came back as a name that does not exist on disk.
- One new msgid, "View image", in the seven non-en locales — matching its sibling
  "View cover", since en carries none of that family and falls back to the msgid.

CUSTOM THEME
- The editor, the colour picker and the swatch grid, ported 1:1 from
  AppearanceSettings.slint and ColorPicker.slint. The 11 editable base tokens,
  their expansion into the full 55-value palette and the on-disk format all stay
  in the shared qbz-theme crate, so a theme authored in the shipping Slint build
  already rendered here and now round-trips both ways.
- Hue is normalised 0..1 at every Qt.hsva boundary; the reference stores 0..360,
  and porting the number instead of the domain would render every swatch red.
- The first-selection seed is captured BEFORE set_theme persists the slug,
  because current_slug() re-reads it from disk — a seed taken afterwards would
  resolve "custom", find no file and snapshot the default it was meant to replace.
- The in-memory base is dropped when the theme row enters "custom": it is
  memoized for the life of the process and filled at bridge construction, so a
  process that booted without the file would keep serving the OLED default even
  after the shipping Slint build wrote the user's theme.
- The disk write is debounced to drag-end and atomic; the reference persists on
  every drag frame with a truncating write, on a file the other build has open.

ABOUT + WHAT'S NEW
- Both modals, with their producers. render_markdown is transcribed line for line
  from the reference: h1 and h2 collapse to one level, an indent-0 bullet becomes
  a section plus a TOC entry, bold and backticks are stripped rather than styled.
  Text.MarkdownText is a different subset and would have rendered a different
  document from the same source. Pinned by tests, including the real 2.0.2 body.
- The codename is a single const, so the release checklist has one Qt-side place
  to bump.

DIAGNOSTICS
- The panel in Settings > Developer, the Report an Issue modal and its menu row.
- The log bundle carried eight hand-built header fields where the reference
  carries about seventy, so every issue filed from a Qt build arrived with no
  kernel, no distro, no install method, no GPU, no exclusive-mode / DAC /
  sample-rate state and no playback context. The report is injected INTO
  qbz_log::bundle rather than replacing it, keeping the <details> wrapper that
  makes a pasted bundle readable.
- The GTK / WebKit / GSK / GDK rows are CUT. In a Qt process those libraries are
  not mapped, so their runtime column can only read "—", and their saved column
  would come from a graphics.json this binary never reads or writes — foreign
  state presented as this app's configuration.

SHELL
- The four always-on-top overlays (toast, tooltip, art preview, immersive) relied
  on declaration order and carried no z, so any z-bearing modal buried them: a
  toast raised by a background event behind an opaque panel is never seen. They
  now sit in a band above the modals, keeping their relative order.
- build.rs asked cargo to watch ../../.git/HEAD, which does not exist in a git
  worktree (.git is a file). Cargo treats a missing rerun-if-changed target as
  always-dirty, so the whole build script — per-shader qsb, the recursive asset
  sweep, cxx-qt/moc codegen — re-ran on every cargo invocation.

Verified: cargo test -p qbz-qt 343 passed, cargo test -p qbz-library 83 passed,
qml_singleton_xref and qml_resolution_audit clean over 35 bridges and 265 QML
files, and qmlcachegen compiles every one of them. Smoke-tested by hand.

vicrodh 016eb3cd23 feat(qt): artist scene, musician page and the shared scene-discovery engine
Both views were absent from the Qt frontend, not partial. This lands them
together with the core engine they need and the two entry points that reach
them.

- qbz-core gains scene discovery ("artists from the same place"): a
  cancellable run with a phase for the progress label and a typed
  SceneDiscoveryError, so a view can tell offline, all-upstreams-failed and
  an honest empty result apart. CancelToken, ScenePhase and SceneDiscoveryError
  are re-exported for frontends.
- qbz-integrations: MusicBrainz location resolution plus its cache layer.
- qbz-qt: ArtistSceneView with its three scene components, MusicianPageView
  and MusicianModal, backed by artist_scene_qt.rs, musician_qt.rs and the two
  bridges. The five-branch musician dispatcher is wired to all six of its
  consumers. Both scene doors are live: the sidebar location link and the
  overflow row that shipped grey with action: "stub".
- Translations: the new msgids in all eight locales.

Three defects fixed on the way, all with the same signature — a comment
asserting a mechanism that does not exist:

- Volume opened at 100 %. The comment claimed the poll loop mirrored it from
  the engine; now_playing::set_volume has two callers and neither runs in a
  local session.
- mbAvailable was documented as "MusicBrainz enabled AND resolved to an MBID"
  while being assigned from the opt-in alone. Consumers now test the MBID.
- Session restore could not resume from a cold cursor ("cannot resume - no
  audio data available") for want of a has_loaded_audio() guard. Investigation
  in qbz-nix-docs/qt-frontend/2026-08-14-cold-cursor-resume.md.

Contract and evidence:
qbz-nix-docs/qt-frontend/2026-08-14-artist-scene-musician/00-CONTRACT.md,
which wins over specs 01..09 and records 20 deliberate divergences from the
reference in section 6.

vicrodh fda56f9ea2 fix(qt): pin the artist jump nav bar and round it at the pane edge
The strip scrolled away with the body; the reference clamps it to the top.
Lifted out of the flow with a slot holding its place, using the reference's
clamp verbatim -- the formula must not add the viewport y or the scroll is
double-counted and the bar lifts ahead of the body mid-transition.

Pinned at the pane's top edge it then showed the square-corner defect already
fixed in Discover: Qt's clip is a rectangular scissor that ignores radius, and
the shell hides its bezel nubs while the dynamic background shows through the
corners, so a full-bleed child has to round itself. Driven off the live y, so
the rounding exists only while the bar is actually at the top -- rounded
corners in mid-page would be a notch with nothing behind them.

vicrodh c2944db973 feat(qt): source-aware playback, session persistence and loading affordances
One batch, committed together because the changes interleave in main.rs and
splitting them after the fact would be a fiction.

Playback routing: a track now carries its source, so a local or Plex row played
from Discover stops being resolved against Qobuz first (the 404s and the long
silent wait before audio). Jellyfin and Navidrome land on the same seam.
Plex tracks stream through the player instead of downloading whole files first;
the feeder moved into qbz-player so both frontends can reach it.

Session persistence, both levels the port was missing:
  - The startup-page preference is finally read. It had been rendering and
    persisting a value nothing consumed. `last_view` is written in the SHARED
    ui_prefs vocabulary, not this port's route ids -- four of the six differ,
    and writing the raw ids would have silently broken the other frontend's
    restore. `on_session_entered` recorded "home" unconditionally, which also
    rewrote last_view on every boot, so the setting could not survive its own
    startup.
  - Queue and active track survive a restart. session_persist was tied to a
    frontend by exactly one type alias, so it moved to qbz-app generic over the
    adapter rather than being copied. Verified end to end: the snapshot restored
    here had been written by the Slint binary, and the exit flush keeps an
    un-consumed resume position instead of overwriting it with the engine's
    idle 0.

Loading affordances: the transport shows a spinner from the moment a play is
dispatched, and the restored session explicitly takes it back down -- a
restored track has no dispatch behind it and no audio ahead of it, so nothing
would ever have cleared it. Cortinilla results now navigate at album and artist
level.

Verified by the offscreen smoke gate and by driving a restore/quit cycle over
MPRIS.

vicrodh 3b03682e09 fix(qt): pane corners stay round under the dynamic background
AppShell hides its BezelCorner nubs while the field is meant to show
through the pane's corners, and Qt's clip is a rectangular scissor that
ignores radius — so any full-bleed child at y=0 squares the pane. The
doctrine was already written in AppShell.qml ("a full-bleed pane child
must round itself; there is no mask that can do it for it here"); these
eight surfaces predated it or, in the two thin bars added with the
ambient port, ignored it.

- The seven fixed 56px headers (Home, Search, DiscoverBrowse,
  ArtistReleases, PlaylistBrowse, PlaylistManager, PlayHistory) take
  topLeftRadius/topRightRadius. Invisible with the background off, where
  the view root paints the same colour beneath. PlaylistBrowse's SECOND
  bar is the category strip at mid-page and keeps square corners;
  PlayHistory keeps its unconditional opaque fill, which is reference
  parity (:43/:34) and a separate question from the corner.
- LocalAlbumView's neutral header band is now gated on the background,
  1:1 with the Qobuz page's atmosphere (AlbumView headerAtmoOn,
  AlbumPageView.slint:168): the two dark backdrops clash and the field
  already provides one. That band had been square since it was written;
  the nubs had been hiding it, and they only stand down when the field
  is showing. Header text there is theme.textPrimary, not the Qobuz
  page's light-on-dark hdrStrong, so it does not depend on the band to
  stay readable — checked before removing the backdrop from under it.

Gate: cargo build -p qbz-qt, both QML audits, offscreen smoke 0
complaints.

Accumulated qt-frontend work from the 2026-08-11/12 sessions (cc),
uncommitted until now: the app-wide dynamic background in both modes
(AmbientField with GPU/Canvas arms, AppShell layering, ambient palette

vicrodh 79e3cdc46b feat(qt): multi-select bulk bar on every Qobuz track listing
The album-page pattern (selection in QML, actions in Rust) generalized:

- New shared engine bulk_tracks_qt.rs: one catalog batch-resolve that
  preserves the selection's visible order, then queue / play-next /
  play-later / add-to-playlist / add-to-mixtape / add-to-favorites /
  make-offline, with the queue context stamped per host.
- PlaylistView: toggle in the header action row, bar inline above the
  column header, selection resets when the playlist changes.
- ArtistView: the Popular Tracks header's dimmed toggle goes live; one
  selection covers Popular Tracks + Appears On + the in-library rows;
  the PopularTrackRow fork gets the select checkbox AND its offline
  cell/menu block stop being inert stubs.
- LabelView: Popular Tracks gets the same treatment.
- AlbumView: the bar moves from a floating overlay to the inline spot
  the Local Library album view uses (bar in flow, content below).

vicrodh d112c726b6 fix(qt): custom album covers propagate to every surface
The per-builder sweep was whack-a-mole — the report caught empty cards
in Home > Recently Played Albums and the NPB, and mosaics still showing
the Qobuz art. Overrides are keyed by album id but most surfaces carry
only the art URL, so the link is now the artwork HASH: every size
variant of one Qobuz cover shares its filename stem. Setting a cover
records hash -> path in a Qt-side store (custom_cover_keys.json — same
reason as the playlist store: the Slint file round-trips known keys
only), the album page backfills it for covers set before the map
existed, and artwork_qt's cached_path / cached_raw_path answer the
override for any URL whose hash has one — cards, NPB, MPRIS, queue,
collage tiles, no per-surface wiring. download_missing skips overridden
URLs.

vicrodh a53e8a7af7 feat(qt): custom covers for playlists + the app-wide custom-art sweep
Two halves of one feature:

- Playlist custom covers (Qt-first; no Slint counterpart yet): the
  playlist header cover gets the cover menu (Add/Change/Remove) and the
  lightbox on left-click. The store is a NEW file,
  custom_playlist_covers.json — a `playlists` key inside the shared
  custom_artwork.json would be silently dropped the next time the Slint
  app wrote an override (its store round-trips only known keys). The
  override beats the playlist's own Qobuz graphic AND the member-cover
  mosaic on the header, the sidebar rows, the cards and the library
  grid.
- Album custom covers now apply everywhere, not just the album header:
  doc builders route an album's art URL through
  cover_artwork_qt::prefer_album_cover (the override's path flows
  through the ordinary artwork pipeline — artwork_qt::classify's
  LocalFile arm resolves it synchronously, no QML change). Swept: album
  page carousels (more-from-artist / suggestions / Last.fm similar),
  artist page releases, search result cards, and the playlist mosaics
  (a member album with a custom cover contributes THAT art to the
  collage tiles).

vicrodh 83b8bd8890 feat(qt): offline downloads + multi-select on the album page
Two AlbumView parity features sharing the row machinery:

OFFLINE CACHE (the menu rows and the per-track state the report was
missing):
- offline_qt.rs activates the per-user OfflineCacheState on login /
  session-restore / offline-session (one fan-out point in
  bind_per_user_stores) and tears it down on logout — same on-disk
  store as the other frontends, so copies made in Slint/Tauri show here
  and play here.
- playback_qt's play funnel now passes the active cache + the row sink
  to play_track_resolved (it passed None, None: the offline tier was
  unreachable even for downloaded tracks).
- offline_cache_qt.rs ports the action set: cache_track / cache_tracks /
  cache_album / redownload_album / remove_cached / refresh_cached, with
  toasts and a bridge-signal row sink (trackCacheStatusChanged).
- TrackRow's download column is live: cloud / spinner / accent check /
  red alert per status (0/1/2/3/4), click map ready->remove else
  download, and the context menu's offline block (Make available
  offline / Refresh / Remove). Status is seeded per row from the
  session cached-id set (album/artist/label/for-you docs) and pushed
  live over the signal.
- Album ⋯ menu: "Make available offline" swaps to "Refresh offline
  copy" on the live all-cached aggregate.

MULTI-SELECT: the toolbar toggle is live; selection state stays in QML
(LibraryView precedent), rows check off in select mode, the bulk bar
carries the reference's full inventory — select-all, play-next,
play-later, queue, add-to-playlist, add-to-mixtape/collection, Add to
Library, make-offline, clear — and the Ctrl+A/Escape router duck-types
the view's selectAll/exitMultiSelectMode like the other tabbed views.

Still out (documented in place): the Offline Manager view, the row
padlock on unlock, per-disc actions, playlist-level cache button.

vicrodh 704fd7e60a fix(qt): artist Latest-release card renders its data again
The card bound `artist.lastRelease.*` unqualified, and inside an
AlbumCard instantiation the bare name `artist` resolves to the CARD'S
OWN string property — a string has no .lastRelease, so every binding
fell back to "" and the card rendered as an empty tile (section visible,
no art, no title) while the grids' modelData-driven cards were fine.
Caught live on a VNC-driven session: the published document carries the
full lastRelease object; only the QML scope shadowing ate it. Every read
in the block is now root.artist.lastRelease.

vicrodh af95ce164a fix(qt): search top-result track hero no longer invades the Artists rail + crown icon
Two Most-popular regressions on the search results page:

- When the top result is a TRACK, the hero painted from its slot's center
  ~100px into the Artists carousel: SearchTrackHero's root Rectangle had
  no size, and a bare Item's implicit size is 0x0 (it does not size from
  children), so the slot's horizontalCenter anchor pushed the whole card
  sideways. The artist/album arms carry explicit sizes and never shifted.
  The hero now declares its 200px width explicitly.
- The header glyph was "award", which reads as a mic. The reference uses
  the crown (SearchResultsView.slint:584); crown.svg is ported into the
  icon masters (primary + the warning bake) and the header uses it.

Both verified live on a VNC-driven session with the exact "all things"
search from the report.

vicrodh d9b1c26ff3 feat(qt): album page parity — cover menu + lightbox, header actions, album info modal
Four wired surfaces on AlbumView, all previously inert stubs:

- Cover menu (right-click, AlbumPageView.slint:300-370): Add/Change/Remove
  custom cover over the SAME custom_artwork.json store the Slint app uses
  (a cover set in one app shows in both), Open in browser, Save as…. Plus
  the NEW lightbox (menu entry + left-click): the art at its best available
  quality fitted to the window, custom override preferred.
- Header action row: radio (the existing foryou_qt album-radio seam),
  booklet (visible when a PDF goody exists; downloads via save-as — no
  in-app reader, like the reference), and add-to-mixtape/collection — the
  MyQBZ picker's Accepts engine already lets albums target Collections
  (the Tauri rule), so the button just feeds it.
- Album Info modal (the extensive one): fresh /album/get → credits grouped
  through the shared qbz_qobuz::performers parser, per-track copyright,
  review tab when the album has editorial text, label link, musician
  navigation, per-track play in album context. Tauri layout (left fixed
  meta column, right scrollable tabs) per the project ruling for this
  feature; the header's label link is wired along the way (LabelView has
  existed for a while — the POC-NOTE was stale).
- … menu: Add to playlist (the loaded view's track ids into the picker),
  Add to mixtape, Share Qobuz link, Share Album.link (UPC -> Deezer ->
  album.link, #514 path — the resolver half of share.rs is now ported for
  the album arm). The offline rows stay out: no Qt album-cache seam.

i18n: "View cover" + "Could not load the image" catalogued in all seven
locales. Gate: both QML audits + 305 tests + debug/release builds green.

vicrodh 28c04bd990 docs(qt): correct the stale search notes
The two whose falsifying commit does not touch their file, so R7 rule 2
could not put them beside the code.

QbzEmptyState claimed it had consolidated SearchView's and Cortinilla's
no-results states. Neither uses it - both draw their own line inline, and the
cortinilla's is a single 28px row inside a dropdown rather than a centred
block.

SearchView's SOURCE note justified its Qobuz-only assumption by saying the
local sections "are not ported". They are now. The assumption still holds for
the results PAGE, which is Qobuz-only, so the note is narrowed rather than
deleted - the cortinilla is a different document whose rows carry their own
source field.

vicrodh 4806584ee2 feat(qt): local "View more" routes into the LocalLibrary tabs
The three local sections' View more links now leave the search surface
entirely and land on the matching Local Library tab. Sending them to the
Qobuz results page instead would show a page with no on-device content at
all, which reads as the link having done nothing.

  local-album  -> Albums tab
  local-artist -> Artists tab
  local        -> Tracks tab, pre-filtered with the live query

The query pre-filters the TRACKS tab only. Albums and artists have no search
box of their own, so handing them a query would be a lie - the list would
come back unfiltered while something claimed otherwise.

The active tab is QML-owned state, so the route is a pending property the
view consumes, mirroring the localPendingArtist mechanism that already
existed for "go to artist" on a local album. It is released after being
applied, because the property CHANGE is the trigger and an unreleased route
could not fire twice in a row. The consumer also runs on mount, so a route
set while the view was unmounted still lands.

Setting the tracks filter writes the view's own search state as well as
issuing the query, or the search box would render empty next to a filtered
list.

vicrodh fa433d465b refactor(qt): extract search_bridge.rs from the QbzBridge god-object
QbzBridge carried five domains (Settings, Search, Playlist, Genre filter,
Discover config); its own boot() comment called the split "TEMP (phase 23)".
TRACK-RULES section 2 requires one cxx-qt bridge per domain. This moves the
Search domain out verbatim, ahead of the cortinilla parity work, so the
refactor and the behaviour change stay separately reviewable.

QbzSearch (search_bridge.rs) takes 7 properties and 11 invokables. Two
deliberate changes ride the move:

  - selected_index -> cortinilla_selected_index. It is cortinilla-only
    state and the bare name on an app-wide singleton is a collision hazard.
  - cortinilla_scroll_y f32 -> f64, unifying with the immersive twin in
    immersive_bridge.rs, which was already f64.

cortinilla_query is declared here but not yet wired; C2 wires it, which is
what makes Enter carry the text the user actually typed instead of the last
successfully loaded payload's query.

Every Rust writer of a moving property was re-pointed BY HAND, never by
regex over the multi-line ui() closures: the seven crate::ui( sites in
search_qt.rs plus two that live outside it and that the QML-only xref audit
cannot see - settings_qt.rs (the live Settings > Appearance path) and
main.rs toggle_intelligent_search. All 48 QML consumer sites across
Cortinilla.qml, HeaderBar.qml and SearchView.qml were updated, including the
one Connections block, whose onSelectedIndexChanged handler was renamed with
its property.

A stale 6.0 base in flat_index_content_y is left in place and annotated: it
mirrors a Flickable viewport margin rather than content space, so every row
reports 6px low. C4 corrects it with its unit test; this commit is a move.

Contract: qbz-nix-docs/qt-frontend/2026-08-03-cortinilla-parity, commit C0.

vicrodh ec8588687b feat(qt): artist page parity - load more, section sort, discography
The release-section "Load more" fetched a page and appended it to a structure
no view ever re-read. The handler pushed IN PLACE into the object behind
`readonly property var artist: JSON.parse(QbzArtist.artistJson)`, and the
releaseSections projection returned that same array on the unfiltered arm, so
both Repeaters were re-handed the identical reference and nothing was dirty.
The tree's own rule, written in cards/PlaylistCollage.qml: rebind requires a
NEW object reference. A second bug sat on the same path - the artist document
republishes progressively (stories, then each MusicBrainz section as it
resolves) and every republish re-runs the parse, wiping anything appended, so
fixing only the first would have left a bug that looks random. Both
pre-existing; the in-flight placeholder added earlier is what made an
always-silent no-op visible.

Appended pages now live in an overlay keyed by release type. It survives a
republish, emits new arrays so the Repeaters rebuild, dedupes by album id,
carries the reference's 4-page cap per bucket (artist.rs:718-720, which hands
off to the discography page beyond it), and is guarded against a page
requested on one artist landing on another's grid - releaseSectionReady
carries no artist id and every artist has an "album" bucket.

"See discography" was a pointer-cursor MouseArea with no onClicked under a
POC-NOTE saying the page was out of scope. ArtistReleasesView.qml +
artist_releases_qt.rs port ArtistReleasesView.slint: infinite scroll rather
than a button, plus the loading, error-with-retry, empty and offline arms.
The album page's "More from <artist>" view-all is a second door to the same
page. Its paging offset counts what the SERVER returned rather than the
rendered row count the reference uses: blacklist filtering and id dedupe make
the rendered count smaller, so the reference re-requests seen rows and skips
the tail whenever the blacklist is non-empty.

The per-section sort was a dimmed Rectangle with no MouseArea, under a
comment asserting no seam existed. It is now a real QbzSelect with the
reference's five options and index mapping, persisted per release type in
artist_prefs. Choosing "Default" after a sort does not restore the server
order until the page reloads - that is the reference's behaviour
(album_map.rs:262 is a bare no-op arm and resort sorts the live model), kept
deliberately rather than diverged.

Also, two visual fixes from the same round that share these files: Popular
Tracks drew its cover at radius 8 where the shared rows/TrackRow.qml uses 4,
and the album page's rail mounts said `width: parent.width` inside a Column
with 32px padding - QML padding shifts children without narrowing
parent.width, so the rails hung 32px off the right and the right page chevron
landed outside the window.

Carries scripts/qt-diag.sh, which has been sitting untracked since the
rendering round: it answers "which backend is this actually running on" from
a real graphical session, refusing ssh and refusing offscreen because either
would answer the wrong question. That refusal is the point - the doctrine it
disproved ("shader effects render nothing on this port's software path") came
from an offscreen observation, and offscreen forces software by definition.

vicrodh edbc037b0f feat(qt): Rust share seam, and fix the dead label share link
The port had no clipboard seam at all. share_qt.rs ports the URL builders and
the clipboard from crates/qbz/src/share.rs:1-70. The long-lived
OnceLock<Mutex<Option<Clipboard>>> is copied verbatim with its reason:
arboard ties the offer's lifetime to the LAST live Clipboard object, so a
create-per-copy port passes on KDE, which runs a clipboard manager that
accepts the handoff, and silently loses the text everywhere else (#514).
arboard carries the wayland-data-control feature at the same pin the
reference uses; without it arboard is X11-only and every copy fails on a
Wayland-only session.

The label header's Share was not merely silent - it copied a link that does
not resolve. open.qobuz.com has no /label/ route. The host is per-ENTITY, not
per-app: track and album on open.qobuz.com, artist, playlist and label on
play.qobuz.com. That asymmetry is why the five builders are ported as a set
and why no call site formats its own URL any more: this one did, and got it
wrong. QbzHome::label_share now copies play.qobuz.com/label/{id} and raises
the "Link copied" toast, 1:1 with main.rs:13164-13178, and the QML
Loader/TextEdit clipboard hack it replaced is deleted - its own comment
claimed there was no toast seam, which stopped being true when toast_qt.rs
landed.

Only the URL builders and the clipboard are ported. share.rs:72-184 is the
Song.link/Odesli resolution, which applies to tracks and albums; artists and
labels are link-only, so porting it now would be dead async HTTP.

LabelView also adopts QbzLoadMore here - its two changes share the file.

vicrodh 6f4fb72f57 feat(qt): shared QbzLoadMore with an appended-page skeleton
Five hand-rolled "Load more" buttons existed in three visually distinct
shapes. One control now carries all three arms, so the idle appearance of
every site is unchanged. While a fetch is in flight it draws a QbzSkeleton
composite BELOW the button - the owner asked for below - which is one
animator for the whole placeholder row, with settleMs 8000 so a fetch that
never returns stops shimmering instead of pulsing forever. Idle it costs
nothing: the block lives behind an inactive Loader, so mounting the control
changes no pixel on a page nobody has clicked.

SearchView had half of this already, and the half it had was on the wrong
side: a skeleton ABOVE the button, on the albums tab only. All four tabs now
use the control, each with its own real cell pitch and row shape rather than
the albums tab's numbers copied across.

AlbumCollection gains an opt-in tail fade (armTailFade) for the arrival half
of the round. It is keyed by the set of ids on screen at click time, not by
an index threshold: the label page sorts its grid, and under any order but
newest a fetched page interleaves, so a threshold would re-fade albums that
never moved - the flicker the fade exists to avoid. It also lets grouped mode
fade, where there is no flat index at all. Inert unless a host arms it, so
Discover Browse and Play History are bit-for-bit unchanged.

vicrodh 8776ebe82d fix(qt): carry the real track data into every queue, and shuffle for real
Two defect classes the owner found by playing music, both of them the port
diverging from a reference that gets it right.

QUEUE TRACK FIDELITY. The reference has ONE builder, make_queue_track
(playback.rs:2426), and it takes the raw Track, so bit_depth and sample_rate
come straight off the API model. This port forked that into ten builders and
five of them mapped from a DISPLAY ROW instead — a row that carries
qualityTier / qualityDetail / qualityLabel, the already-formatted strings, and
no raw numbers. Those five hardcoded bit_depth: None, sample_rate: None:
playlist_qt, artist_qt, label_qt, library_qt and playback_qt's feed_queue_track.

The consequence reached the user as a broken NPB AudioStamp: the track edge
seeds quality_state from those same numbers, so starting playback from a
playlist, an artist page, a label page or a Library-feed row left TRACK_MAX at
zero and the badge could not render a complete bit-depth / sample-rate line.
Starting from an album was perfect, which is what made it look intermittent —
the album path was one of the five that had always built from the raw Track.
The rows now carry the numbers alongside the strings, because the producer
derives the strings FROM those numbers and was discarding them; parsing
"24-bit / 96 kHz" back into integers would have been a second source of truth.
The same builders were dropping artwork_url, which is why the queue sidebar
had no covers for playlist-sourced or local rows.

Also fixed here, found while tracing: local_playlist_qt::play shipped
context: None, so set_queue_stamped fell through to derive_context, which
answers None for a many-album playlist. The song card then used its per-track
album fallback and pointed at a local album_group_key instead of the playlist.
Pre-existing for the header Play, but a guard added last round routed the row
click through the same path, which turned it into a regression there.

SHUFFLE. set_shuffle(true) only randomises what comes NEXT, so four entry
points raised the mode and then played the list's #1 track: the album header,
the playlist header, the local-playlist header and every local play_rows call.
The one track the user actually hears on pressing Shuffle was deterministic.
All four now mix their own list with the xorshift Fisher-Yates the port
already uses in play_track_list_in and start at the top of the mixed order.
The mode stays raised so playback continues shuffled past the list. The owner
traced the flag-and-play-from-the-top shape to a very early Tauri experiment;
it is not the behaviour anywhere.

Not addressed, going to a separate pass: a Qobuz playlist carrying local or
Plex sidecar rows. The reference routes those through the local snapshot
(playback.rs:3488 is_mixed); this port has no sidecar concept on playlist_qt
at all, so such a row is still typed as qobuz. Same defect class, one layer up.

vicrodh 35508b5f87 fix(qt): the defects found smoking the playlist and My QBZ round
Un-following a Qobuz playlist left it in the sidebar and in My Library.
toggle_follow called unsubscribe_playlist and settled the ownership snapshot
and stopped there, so the row only left at the next full refetch. Both
surfaces are patched directly now, in both directions: following from a card
buys the metadata with one get_playlist rather than re-reading
getUserPlaylists, which lags the write. The un-follow collapses a
hearted-and-followed playlist to the one row the next load will actually
produce instead of dropping it, because the local heart is a library.db flag
that survives the unsubscribe — removing every row made it vanish and come
back, which is the original complaint wearing the other shoe.

The Plex mark on album cards was a hard-drive glyph tinted accent — a blue
hard drive — and the three Qobuz kinds drew no badge at all. The badge now
ports discover/AlbumCard.slint:326-354 exactly: 24x24 at radius 4 pinned
bottom-right with a 6px inset, plex-logo untinted at 16, qobuz-logo at 18
(22 for a download), the purchase arm gold on its amber chip, hard-drive
white at 14 for local only. The brand marks are plain Images: routing them
through QbzIcon floods every pixel with the tint and flattens a logo to a
silhouette. SourceIcon moves to controls/ since it is no longer local-only,
and every other surface drawing a hard-drive was audited against its .slint.

The local album detail loses the two nav chevrons above the art. They are a
Tauri-era leftover from before the app had global navigation.

My QBZ used a bespoke card in the grid. MyQbzDetailCard is deleted and the
standard cards/AlbumCard is mounted with its overlay. localMode bundled four
separate things — action routing, the heart, the pin and Block this album —
so a multi-source container had to switch all four off together; it is split,
and the catalog affordances now follow the ITEM. On a Qobuz cell the heart
works through the shared favourite seam; on a track, playlist, local or Plex
cell it is absent rather than dead. Row covers carry two rungs: the list keeps
_50, the grid gets _600. Not the _230 that would merely cover a 200px card —
the complaint was that the cover reads softer than a normal AlbumCard, and a
normal AlbumCard is fed image.large, which IS _600. _200 is not a rung the
CDN serves at all (it answers 404).

The My QBZ grid sets reuseItems, and AlbumCard assigns to its own isFavorite
and isPinned when toggled, which destroys the binding that fed them. A
recycled delegate therefore showed the previous row's heart and the click
added the new album while the glyph said remove. Restored with the
Qt.binding idiom this port already uses on TrackCard, PlaylistCard and
TrackRow.

The details view no longer force-opens every row on entry, and the per-row
open state persists.

Library > Artists showed placeholders for nearly every portrait. The side
panel never reported its artwork window — the one caller of
libraryArtworkWindow is LibraryView.reportWindow, and the panel had no
report call at all, so no key ever reached the resolver and artMap stayed
empty for its rows. The rail now reports through that same path, with the
section-header sentinel reportWindow already skips. Note the reference has
no portrait fallback either: an artist Qobuz serves no image for is a
placeholder on both sides.

vicrodh a16cf56c86 feat(qt): playlist manager, folders, importer and the Library parity round
Ports the whole playlist-organisation domain, which had no counterpart in
this frontend, plus the Library work the owner asked not to defer.

Playlist Manager. New controller (playlist_manager_qt, _rows, _ops) over the
already-ported folders_qt repository, which until now had zero consumers.
Grid, list and folder-tree modes; sort, filter and search; folder cards and
chips; drag reorder and up/down arrows. Reached from the sidebar's "..."
menu, whose New folder / Manage playlists / Import rows had been rendering
dimmed and inert behind a comment saying the seam did not exist.

Folders. QbzFolderEdit plus the create/edit modals and PmFolderIcon: preset
or custom-image icons, colour, hidden flag, delete. Deleting a folder nulls
its LOCAL members' folder_id explicitly, because the app keeps the
foreign_keys pragma off, so the schema's ON DELETE SET NULL never fires for
them.

QbzPlaylistEdit. One shared rename/description/delete editor replacing the
inline popup in PlaylistView. Three corrections the old path had wrong: the
description is carried through a rename instead of being written as NULL,
a FOLLOWED playlist routes to unsubscribe (playlist/delete returns 200 and
silently no-ops on a playlist you do not own), and the post-delete back
navigation is conditional on actually being on that playlist's page, so
deleting from the manager no longer navigates you off it.

Importer. Spotify / Apple Music / Tidal / Deezer, over the shared
qbz-playlist-import crate.

Picker local mode. The reference's four-case matrix — target local or Qobuz,
payload local refs or Qobuz ids. Local playlists list unconditionally and
Qobuz ones only when online. Local refs onto a Qobuz playlist write the
library.db sidecar at next_playlist_sidecar_position(pid, qobuz_count); the
0-based enumerate the reference used before collided slots and lost rows.
The carried payload can no longer be parsed as a catalog id when it is a
library row id. Unblocks the local bulk add-to-playlist.

Library. A-Z jump strip, Albums list mode, Artists side panel, per-tab
persistence and multi-select. Preferences land in the same
<data-dir>/qbz/favorites_ui.json the shipping build writes, so switching
between the two frontends keeps them. LibraryView is split into
views/library/ on the way past 1800 lines.

Local library. Group-by now persists; playback queues the order on screen
rather than the SQL page order; switching album-identity mode invalidates
the Artists tab; artist matching folds diacritics and compares normalized
credit parts, so "Air" stops listing "Airbourne" and "Beyonce" stops being
two artists.

Offline. activate_offline never persisted a last-user marker, so every
per-user path resolved to None and all local reads came back empty; a
session that started offline saw no local playlists at all. The sidebar's
load-once latch was function-local and therefore unreachable from the logout
reset, so a second login never rebuilt the tree. Both are session-scoped
now, and the sidebar Refresh row runs the local-safe verb instead of being
dimmed with no way to recover.

Also fixes, found while verifying rather than reported: artwork derivatives
were written straight to their final path, so a QML Image resolving one
mid-encode opened a truncated png and Qt cached that failure against the URL
for the rest of the session; Library's track group separators referenced a
Component declared in another delegate's scope and could never render; the
genre filter was drawn on Tracks and Albums but applied only on All; an
All-feed row called a player method that does not exist; and the sidebar's
drop-hot highlight used Slint's #RRGGBBAA literals in Qt's #AARRGGBB slot.

17 new msgids across all 8 locales.

vicrodh d1862e90da fix(qt): the Source column draws the real Qobuz and Plex marks
Owner: "si es de qobuz, icono de qobuz, si es de local (folder o plex) cada uno
tiene sus svg; Slint y Tauri los tenían bien."

They did. The port did not, and the reason was an asset gap rather than a
styling choice: `qobuz-logo-filled.svg` and `plex-logo.svg` were never carried
over from the Slint tree, so `SourceIcon` substituted `cloud-download` for every
Qobuz kind and a tinted `hard-drive` for Plex — drawing "downloaded" and "local
file" where the design calls for two brand marks. Both assets now live in
`qml/assets/brand/`, beside the Discogs / Last.fm / MusicBrainz marks that are
there for exactly the same reason.

The rule this restores is one `SourceGlyph.slint:4-8` calls load-bearing: the
full-colour logos render UNTINTED and only the monochrome local glyph is tinted,
to MUTED text and never accent. Slint spells out why — routing a logo through a
tinting primitive "would turn the logos into a flat accent silhouette, the bug
this primitive replaces". `QbzIcon` floods every pixel with its tint, so the two
logo arms deliberately do not go through it.

`qobuz_purchase` is the one arm that must tint a multi-colour asset (the same
mark in #eab308 — the colour is what says "purchased"), so it is the one arm
that uses an effect, and it degrades on a software renderer to the untinted mark
rather than to nothing.

The two ROW call sites now pass SourceGlyph's own numbers (15px, muted) instead
of inheriting the version picker's (14px, secondary) — the two Slint components
this file stands in for disagree on both, which is why they are properties.

Verified by driving the app: the Qobuz rows show the Qobuz mark and the Plex
rows the gold Plex chevron, in their own colours, with zero "Cannot open" in the
log.

vicrodh 83c1aec4f5 feat(qt): collapsible rows in the My QBZ detail, and ephemeral leaves no trace
**The accordion the owner asked for.** Each expandable row gets a chevron;
clicking it opens THAT row's tracks inline and nothing else. Verified by driving
the real app: in list mode every row is collapsed with the chevron pointing
right, clicking row 3 — a PLEX row, so the hybrid path — flips its chevron,
renders its three tracks with durations and quality badges, and leaves rows 1,
2, 4 and 5 untouched.

This is a DELIBERATE divergence from both references, decided by the owner with
the facts in hand: neither Slint nor Tauri has a per-row accordion. Both render
inline tracks only as a view MODE, for every row at once, and both say "no
chevron" in their own comments (MixtapeDetailView.slint:1139,
MixtapeCollectionDetailView.svelte:124-127). The owner first believed Tauri had
it, asked for the code to be checked rather than the comment, and on the
evidence chose the accordion anyway. Do not "restore parity" by removing it.

Built additively on machinery that already existed: the document already carried
`canExpand` / `inlineTracks` / `expandLoading` / `tracksLoaded`. What was added
is per-row OPEN state in Rust, a toggle invokable, and lazy per-row fetching —
opening a row fetches only its tracks, once. The "expanded" view mode survives
and now means "open all", sharing ONE notion of open rather than a second
parallel state.

Also here:
- `body`'s `anchors.bottomMargin: 100` shrank the list VIEWPORT; in the .slint
  that 100px is padding INSIDE the Flickable, i.e. scroll runway. Measured on
  screen before the fix: the last row clipped mid-height with ~85px of dead
  band under it.
- `apply_resolved` cloned and serialised the WHOLE document per resolved item
  (34 serialize→parse→patch cycles for one collection, 200 for a big one, on the
  GUI thread), and `patch_expanded` did the same while the document carried
  every loaded item's inline tracks — O(n²).
- The DEAD affordances the audit filed against the modals and the grids.

**Ephemeral honours its name** (owner rule): an ephemeral folder plays and
queues, and writes nothing durable. Recently Played and Most Played are now
guarded — an ephemeral album played through would previously have outranked real
albums in Most Played, one row per track start. The Slint reference does NOT
have this exemption; that is a gap in both frontends, not a Qt regression, and
this does not restore parity by removing it.

Two stores were deliberately NOT changed and need the owner's word: the
scrobblers and Discord presence. Neither is "las bibliotecas" — nothing is
stored on our side — but both publish the track to a third party, so if "ni now
playing ni nada" is meant literally they belong in the same decision. The

vicrodh b6cf06ff2a feat(source): wire My QBZ through the seam, and land the owner's container rules
Stage 2. The measured win: opening a 34-item collection now costs **2** library.db
opens instead of 23-34 — the local source owns a pooled handle and hands out no
guard, only `with(|db| ...)`, so a `!Send` `&LibraryDatabase` cannot cross an
await either. Bug 1 from the seam design is dead by construction, not by care.

The owner's rules, decided today, now live in one place instead of eight:
- **Collection** takes albums, singles and EPs from ANY source — qobuz, folders,
  Plex, and whatever is added next. **Mixtape** takes albums, playlists and
  tracks. This was a single boolean (`restrict_to_mixtape`) that could express
  neither release types nor "collections accept local".
- An unsupported combination must never be VISIBLE: the picker stops offering
  the impossible action, and the error stays a log-only safety net. Owner: "el
  bloqueo no debería ser visible nunca, más bien esto hay que ajustarlo en la UI".
- **Ephemeral honours its name** — playable, queueable, and offerable to nothing
  else.
- A row's source comes from the ROW. Eight QML sites built the add-to-mixtape
  payload with `"source": "qobuz"` written as a literal, so a Plex or local
  track was stored as Qobuz and afterwards could not play at all: the app asked
  the Qobuz API for an id that never existed there.

`QobuzSource` reads the client through a lens on every call instead of holding a
clone. That is not style: `qbz-core` REPLACES its client (core.rs:346 and :384,
both on paths that run before `set_session`), so a cached clone goes stale and
fails silently — the hazard the crate's own doc comment described.

The lens is installed in `on_boot`, first of everything, and finding out why is
the lesson of this commit. The gate was green — build, 142 tests, both QML
audits, a clean offscreen smoke — and the feature was visibly broken: every
Qobuz row showed "No results found", an empty Quality cell and a wrong "SINGLE"
type, while the Plex rows resolved fine. The registry is a OnceLock, so whoever
touches it first BUILDS it, and one built without the lens leaves Qobuz
permanently detached. Only driving the real app surfaced it; the crate's error
string named the cause exactly, which is the one thing that made it a ten-minute
fix instead of an afternoon.

vicrodh ea373a601c fix(qt): four AUDIBLE parity rows — stream errors, seek clamp, label shuffle, Plex keys, Library queue
PARITY-DEBT #7, #15, #17, #4 and #5.

- **#7** the stream error was drained and only logged, so an ALSA / exclusive
  failure — guaranteed inside Flatpak and Snap — froze the bar at 0:00 with no
  explanation. It now toasts, with the sandbox-aware rewrite the reference
  carries (playback.rs:5093-5115). This is the support issue that fix was
  written for.
- **#15** seek was clamped to the full duration instead of the downloaded
  fraction, so the head could be dragged into bytes that do not exist. The
  poll loop publishes `npSeekableMax` and both bars clamp to it, matching
  SeekBar.slint:93-98. The cache overlay was already drawn and purely
  decorative.
- **#17** a label page's Shuffle called `set_shuffle(true)`, turning the GLOBAL
  shuffle mode on and leaving it on for everything played afterwards. The
  reference shuffles the vector in place and never touches the mode.
- **#4** a `plex:<hash>` album-boundary key was passed where a Plex rating key
  belongs, so the fetch 404'd and the PREVIOUS track kept playing under the new
  card. Guarded at both sites, 1:1 with playback.rs:668-680 (`b5c1a76e`).
- **#5** clicking a track in Library played exactly one track and stopped. It
  now queues the whole VISIBLE list from the clicked row (`order_by_visible`).

The Library row play needed one edit outside its author's lane, which the
singleton xref caught before the build did: `QbzLibrary.libraryPlayVisible` was
called from QML and implemented in `library_qt`, but never declared on the
bridge. That is precisely the failure the xref exists for — QML resolves
singleton members lazily, so a missing invokable compiles clean and throws when
the user clicks. The QML had shipped a `typeof === "function"` feature-detect
with a fallback, so it degraded instead of throwing; the invokable now exists
and the fallback is dead code by design.

vicrodh 1c2bdb749a fix(qt): the My QBZ detail delegates read the live row, not the model's snapshot
The whole in-place patch path was a silent no-op, and it took the Quality
column and expanded mode down with it.

`model: root.rows` is a JavaScript array. QQmlDelegateModel SNAPSHOTS such a
model, so a delegate's `modelData` is the engine's own copy of the element, not
the object sitting in `root.rows`. `syncRows` patches with `Object.assign` on
purpose — reassigning the array resets contentY and throws the user to the top
of a 200-item collection — and then bumps `patchRev` to re-evaluate the
bindings. Every part of that worked except the last one: the bindings
faithfully re-read the STALE copy.

Measured before the fix, driving the real app over VNC: 34 items resolved
Rust-side with correct tiers (26 get_album, all 200 OK), 34 publishes, 71 QML
refreshes, `syncRows` taking the patch branch every time — and the Quality
column sat on its loading dots forever, byte-identical five minutes apart.
Expanded mode rendered no inline tracks at all, for exactly the same reason:
`inlineTracks` is delivered by that same patch.

The fix is to index the live array: `patchRev` stays the dependency and
`root.rows[index]` is the object Rust actually patched. `modelData` remains the
fallback for the frame where the array and the delegate model are momentarily
out of step. No array reassignment, so the scroll position is still preserved.

After: the badges resolve to "CD 16-bit / 44.1 kHz" and the inline track lists
render with their durations and per-track badges.

vicrodh 494596616e feat(qt): port the Blacklist manager for artists and albums
The port had a 67-line settings row showing two counters and a header saying
the Manage chevron was "NOT shipped — this port has no Blacklist Manager view
for it to open". The Slint has 1,114 lines of manager plus the consumer surfaces
that make the feature mean anything.

- src/artist_blacklist.rs is a 1:1 port of the reference's per-user lifecycle,
  including the fail-open asymmetry (is_enabled reads TRUE when there is no
  session, everything else false/empty) and the byte-identical NO_SESSION_ERR.
  src/reco_dismiss_qt.rs carries the reco-dismissal store. Both are bound in
  ALL THREE session-activation paths — the offline one included, because the
  reference records that Tauri never bound it offline and blacklisted artists
  leaked into offline surfaces — and torn down on logout, or the next account
  inherits them.
- The manager view: three tabs (bordered, ADR-008 — no pills), search, sort,
  the enable toggle, the disabled warning banner, the four body branches per
  tab in their load-bearing order, windowed lists, and the clear-all confirm.
  Reached from Settings only, exactly like the Slint; no sidebar entry.
- Every one of the ten store mutations publishes TWICE — its own document and
  publish_settings() — because the Settings counters live in a different
  document and nav_qt::back() re-runs no per-view load. Without it,
  Manage -> unblock -> Back showed pre-mutation counters. The Slint gets this
  free from a shared global.
- The search field is driven imperatively, not by a binding: QbzLineEdit's X
  used to destroy the binding, after which the box went blank while the list
  stayed filtered.
- Consumer surfaces, which is where the feature actually lives: the album card
  and album list row gained "Block this album", the artist card gained the
  3-arg "Not interested", the album header menu gained Block/Unblock swapping
  on state, and the artist page gained the Show/Blacklist flip plus the amber
  hidden banner with its "Show artist" button. album_qt and artist_qt now seed
  isAlbumBlocked / isBlacklisted at document build time — without the seed an
  already-blocked album offered "Block this album" and the first click
  UN-blocked it, the same lie the pin glyph told before isPinned existed.
- search_qt passed &Default::default() for both blacklist snapshots, so nothing
  was filtered anywhere and a greyed row still played. It now passes the real
  snapshots at both call sites.
- The 17 toasts the spec had dropped for want of a toast host are wired: that
  premise stopped being true when toast_qt landed, and a Clear All that failed
  with NO_SESSION_ERR was completely silent. Their msgids are in all eight
  catalogues; the five album-axis ones existed only in es and nl.

Also fixed in passing, pre-existing on this branch and unrelated to the
blacklist: ArtistView's library tab read `libTracks` unqualified from a child
of the object that declares it, which QML resolves against the component root,
not the enclosing object — so the "Tracks" heading threw a ReferenceError and
never rendered. Found by forcing the artist route in the offscreen smoke, which
no earlier gate did.

vicrodh acf23abc9b feat(qt): port the My QBZ domain — mixtapes, collections and the discography builder
The Slint reference is 3,885 lines of .slint across ten files plus 5,514 lines
of Rust glue over the shared qbz-mixtape crate. None of it existed in the Qt
port; the nav flyout carried a "GAP:" comment and two disabled entries.

Rust (flat in src/, per QTBUG-93443): three bridges rather than one God-object
— QbzMyQbz (grids + detail + edit + cover + mix), QbzMyQbzAdd (the app-wide
picker, kept apart so TrackRow, PlayerBar and the Local Library bulk bars
cannot couple to detail state) and QbzDisco (artist-scoped, reached from the
artist page, never coexisting with the MyQBZ views). Twelve controllers behind
them, ported function by function from myqbz{,_detail,_play,_edit,_cover,_mix,
_add,_prefs,_view_prefs,_builder}.rs. src/toast_qt.rs finally gives the port a
toast host.

QML in qml/views/myqbz/ plus four global overlays. Reused rather than forked:
TrackRow, TrackListHeader, QualityBadgeFull, QbzContextMenu, CardMenu,
QbzCheckbox, QbzSkeleton, QbzScrollBar, RoundedImage. LocalSegToggle and
LocalMultiSelectBar are PROMOTED to controls/QbzSegToggle and
controls/QbzMultiSelectBar (they were ports of shared Slint primitives that
MyQBZ needs too) — a move plus an import fix, with the Local metrics kept as
the defaults so the four Local Library toggles are byte-unchanged and the MyQBZ
call sites pass ViewToggle's own numbers.

Every list is windowed at write time: GridView/ListView with reuseItems and a
cacheBuffer, and expanded mode is an outer recycled ListView whose delegate is
a Column + Repeater, because a nested ListView inside a recycled delegate
cannot size itself. Single-row updates patch in place; replacing the array
resets contentY and throws the user to the top.

Shared controls gained the arms the new views need, with the numbers taken from
the .slint and not guessed: SettingsButton (btnHeight / minWidth /
trailingIconName), QbzEmptyState's four metrics, QbzSelect's `sm` variant
(30px, r6, no outline, 12px label, 14px chevron, 40px narrower —
QbzSelect.slint:74-148), QbzContextMenu.openBelowLeft, and QbzLineEdit gains a
distinct `accepted` signal fired on ENTER ONLY: a modal that submits on
`committed` submits TWICE, because closing it removes focus and fires
`committed` again — a rename would have run twice and a create made two
collections. clearSearch() no longer assigns root.text either; that JS write
destroyed the call site's binding permanently, so Rust could never re-seed the
field after one click on the X.

SourceIcon gained the plain "qobuz" arm it was missing, which had every Qobuz
row in a collection drawing itself as a local file.

Two icons (turntable, image) are baked from the Slint masters into the seven
full tint dirs and registered in MASTERS; three more (circle-check-big,
circle-alert, triangle-alert) back the toast. A missing tint dir or glyph
renders nothing and logs nothing, so this class never surfaces in a build.

vicrodh d4667f5ea9 perf(qt): rounded covers use a real mask, the spectrum ticks at 62Hz, the derivative cache is bounded
The track's "ShaderEffect / ColorOverlay / MultiEffect render NOTHING on the
software path this port runs on" doctrine was measured FALSE on 2026-07-29:
qbz-qt runs on the GPU (OpenGL RHI, threaded render loop, vsync 5.56ms). The
claim came from an offscreen session, and QT_QPA_PLATFORM=offscreen forces
software by definition. Every design it justified needed re-deciding.

- RoundedImage was a Canvas (renderTarget: Canvas.Image) that rasterised with
  QPainter on the CPU AND uploaded a texture per repaint, for every cover in
  the app, purely to round a corner identical in every frame of that image's
  life. It is now layer.enabled + MultiEffect { maskSource } — an FBO rendered
  once and cached for static content. Rectangle { radius; clip: true } cannot
  do this: clip in Qt Quick is a RECTANGULAR scissor and ignores radius.
  maskThresholdMin/maskSpreadAtMin are 0.5/1.0, NOT the 0.0/0.0 that looks
  natural: 0.0 collapses Qt's mask smoothstep to step(0, alpha) and every
  pixel with any alpha snaps fully opaque — measured 0 antialiased pixels at
  radius 40 against the Canvas's 292. At 0.5/1.0 it is 308, ramp [0,51,219,255].
  A software machine keeps the Canvas arm (GraphicsInfo.api), and
  QBZ_QT_ROUND_MODE=canvas pins it on a GPU machine where the mask misbehaves.
- VizSettle drove the spectrum from FrameAnimation, i.e. every rendered frame:
  180fps on this box for data the producer publishes at TARGET_FPS = 30. Now a
  16ms Timer; the wall-clock maths is unchanged.
- SpectrumBand's per-bar y was a SECOND JS binding derived from height. An
  anchor does the same arithmetic in C++ with no binding at all, and each FFT
  frame is materialised into a plain array once per publish instead of being
  read element by element across the JS/C++ boundary. Bindings per tick: bars
  28 (was 56), waveform 48 (was 96), energy 5 (was 10).
  QQuickPaintedItem was investigated and rejected with evidence: cxx-qt 0.7.3
  emits X(QObject* parent) : base(parent), which does not compile against
  QQuickPaintedItem(QQuickItem*), paint() is pure virtual, and there is zero
  precedent for a custom base class in this workspace. Qt 6 ShaderEffect takes
  no GLSL, only precompiled .qsb, which would make the build depend on a Qt
  tool whose path differs on macOS.
- PlaylistCollage point-sampled its mosaic in its own Canvas
  (Context2D.drawImage does not filter when it scales — measured RMSE 0.000
  against nearest-neighbour). It now draws through RoundedImage.
- The scaled-derivative cache had no eviction at all and the .jpg -> .png key
  change had orphaned 1251 files. Boot housekeeping sweeps the orphans once and
  bounds the directory at 64 MB, LRU by mtime. Verified by effect: first run
  deleted 1259 files / 10.05 MB, every run since reports 0, and the directory
  is 14 MB. The eviction is only survivable because RoundedImage clears
  _scaled on Image.Error and re-requests.
- For You artwork patched the rails in place instead of republishing the
  document, which was resetting contentY. HomeView is destroyed on every
  navigation, so the patch map is re-handed on mount through
  QbzHome.refreshForyouArt() — otherwise the Radio rail and the Spotlight hero
  went blank for the rest of the session after one navigation, and the skeleton
  pulse Timer stayed pinned ON, defeating the fix it belonged to.
- Spotlight's placeholder gated on the local path instead of the remote url, so
  it flashed a glyph on a cold cache where the Slint does not.

The retired doctrine is corrected wherever it was load-bearing for a decision.
The pre-baked icon tints are deliberately NOT reopened and no drop-shadows are
added: both are visual changes, not perf fixes.

vicrodh 0c159c141c feat(qt): For You gains Qobuz Mixes pages, Artist Spotlight and Radios
Ports the three sections the tab was missing, against the Slint
implementation rather than invented: the section rails, the cards, and the
mix landing page with its navigation seam so back/forward behave.

The mixes reuse the shared crates for their requests -- the Slint app
already makes them, so nothing new talks to Qobuz here.

Also carries the qt-run.sh portability work needed for the Mac mini:
`free`, `nproc`, `pgrep` and `timeout` all differ or are simply absent on
BSD/macOS. Two of those bit during the first Mac build. `pgrep` exits 1
when it matches nothing -- the normal case -- and under `pipefail` that
killed the script before a single line of output, which reads exactly like
a build that did nothing. And `timeout` does not exist on macOS at all, so
the smoke produced a one-line log over which the grep cheerfully reported
"0 QML complaints": a test that never ran, rendering as a pass. The smoke
now fails outright on a log that short.

vicrodh a3b89107fc fix(qt): table headers line up, the mini rail is centred, tooltips have a background
Three of the owner's visual reports, one theme: geometry that was derived
in two places and drifted.

The track table laid its header out from the LABELLED columns only, so
the heart and the overflow menu took no space there and every label sat
right of the column it names. Header and rows now come from one shared
set of widths, including the responsive arms -- if the header hid columns
on a different condition than the row, the drift would come back only on
narrow windows.

The collapsed rail goes back to Slint's 64px. It had been 50 by owner
request, and the measurement showed why that was the actual defect: the
rail centred its row at 25 while the header's own sidebar toggle, sitting
directly above it, centres at 30. Symmetric padding inside a 50px rail
still reads as misaligned because the eye compares the glyphs to the
header control, not to the rail; chasing it from inside bought the
alignment at the price of a visibly asymmetric hover pill. At 64 both
references land 2px apart and the padding is symmetric again. The row
stays a literal 34 rather than being derived from the width -- deriving
it is what coupled the two tokens and would have silently grown every row
to 48.

Tooltips: the port had none, while Slint has a shell-level overlay. This
adds the overlay rather than a Popup per call site.

vicrodh 6b5226acf9 fix(qt): covers are actually downscaled, and non-square art keeps its ratio
The owner's clue was the whole diagnosis: the same image looked fine at
220px in the hover preview and bad at 150px in a card. So not the source,
and not the URL variant either -- every Qt producer picks exactly what
Slint picks, `large` (600px) into a 200px cell, 3x headroom.

`artwork_qt` was producing the right derivative and `RoundedImage` was
drawing the untouched 600px original next to it. `Context2D.drawImage`
does not filter, so every card was a nearest-neighbour downscale: measured
on a card cropped out of the running binary, RMSE 0.000 against a
point-sampled reference. The preview looks right because it is a plain
Image with smooth+mipmap and never touches this path.

Three defects were latent behind that dead derivative: `thumbnail(w,h)`
does not preserve aspect (46 square covers on disk written as 32x28),
`to_rgb8` matted transparent logos onto black, and the file was JPEG q75 --
more damage than the resample it was meant to cure.

Qobuz playlist art is 800x380, and both the header and the card were
stretching it to fill a square. It now keeps its ratio, and the uncovered
area takes a gradient derived from the image itself, reusing the ambient
colour pipeline rather than starting a second one.

vicrodh d5bf4398ac fix(qt): Library sub-tab switch no longer segfaults, and the pane keeps its corners
Three identical faults in dmesg over three days, all
`segfault at 8 ... libQt6QmlModels.so.6.11.1[420c5]`. `nm -DC` puts that
offset in `QQmlDelegateModel::model()`; the QVariant return means sret,
so %rsi is `this` and address 8 is a null pointer plus the member offset.
`QQuickItemView::model()` reads its d-pointer, checks a QPointer guard and
then calls straight through without testing the value.

The re-entry is `onContentYChanged`, not `onModelChanged` as first
assumed: `setModel()` emits it from inside the window where the old
delegate model is already gone. Switching to Labels re-derives the model
AND clamps contentY to a shorter list, which is the emit -- hence the
intermittency, since at contentY 0 nothing is emitted and nothing
crashes. Reproduced in plain qml6 with no app and no login, and bisected:
readback in onContentYChanged dies, in onModelChanged survives 401 swaps,
cached array survives everything.

The fix is to stop asking the view for its own model. A tree-wide audit
found `.model` is the only member that is unsafe this way in 6.11.1 --
count, contentHeight, indexAt and itemAtIndex all null-check -- and the
three LocalLibrary tabs already cached their arrays, which is why this
stayed a Library-only bug.

Also: `clip: true` is a RECTANGULAR scissor in Qt Quick and does not
follow `radius`, so the album/artist header band painted over the content
pane's rounded corners. Slint clips to the rounded shape on the same
element, which is why the identical structure is correct there. The mask
sits OUTSIDE the frame rather than at a high z, because ADR-009 pins
in-pane modals at z >= 3000 with no ceiling and a z fix would be a
standing arms race.

vicrodh 81c43a114e fix(qt): glyph colours follow the theme, on light palettes and on accent fills
Two defects with one cause: a tint name that means a frozen hex.

"primary" is the legacy alias of literal #ffffff, not Theme.text-primary,
so every control passing it drew a white glyph. On the eleven light
themes that is white-on-light -- the header back/forward chevrons, the
sidebar toggle and the carousel arrows the owner marked. They now pass
the theme-following names, which icon_tint_qt bakes at runtime.

The stale `hslLightness > 0.5 ? "primary" : "black"` workarounds that
predate the runtime tinter collapse into those names, and the qrc floor
underneath them becomes polarity-aware: dir_for() returns "" whenever
the cache dir is unavailable, a bake fails or the theme document has not
been published, and that path used to resolve textPrimary straight back
to the white bake -- reproducing the bug it was fixing, app-wide, in the
degraded state.

On accent fills the fix is a deviation from Slint, approved by the owner
after measurement. A fixed white glyph on Theme.accent falls under 2.6:1
on 16 of the 35 shipped palettes, including high-contrast at 1.70:1 and
wcag-dark at 1.82:1 -- the two themes whose reason to exist is contrast.
Slint hardcodes #ffffff there (CircleAction.slint:72 and three others),
so the bug is upstream. accentText alone is not the answer either: it is
picked for the theme's text ramp and gives 2.56:1 on Rose Pine Dawn,
worse than the black it replaces. So QbzTheme picks the best-contrast
tint by real sRGB luminance against the live accent, and the labels
beside those glyphs use its colour twin -- BrowseGenreButton and
LibraryView were drawing a white glyph next to an accentText label
inside the same pill.

Rounds out the two parity items the same files owe: QbzNavButton gains
the ambient arm from Carousel.slint (wired at the six carousel sites,
not left dead), and QbzCircleAction rounds its glyph to whole pixels the
way CircleAction.slint does.

vicrodh c56fab3c4e fix(qbz-qt): covers were never actually resized, plus the adversarial parity round
**The scaled-cover fix from the last round produced nothing.** The seam ran —
462 requests in one offscreen smoke — and wrote zero files, so the owner was
right that nothing improved. The artwork cache stores files as `.img`, and
`image::open` picks its decoder from the EXTENSION, so every call failed
silently. Sniffing the content instead yields 101 derivatives on the same run.
The header atmosphere had the identical bug and had therefore never produced an
image either, which is why the flat fallback was all anyone ever saw.

Reported as fixed last round without checking that it ran. Verified by effect
this time, not by reading the diff.

The rest came through an analyse / refute / implement / verify pipeline, and the
adversarial passes earned their keep:

- The sidebar mini rail: icons sat left of centre because their slot kept its
  fixed 24px width while the rail collapsed, so the hit target was rectangular
  and off-axis. The rail narrows, rows are square, and the mini state gains the
  folder flyout and tooltips it never had. The reviewer caught a comment
  claiming the width change was a one-token revert when it is two — corrected
  rather than left to mislead the next reader.
- Playback context now travels from every producer, not the handful that
  happened to stamp it.
- Collapsible per-tab search in Library, and label artwork.
- Every View-all destination Home offers, plus the label page and its releases.
- Collapsing the sidebar drops a Large bar back to New, live, without
  overwriting the user's persisted preference.

vicrodh 2a5b5ac16e feat(qbz-qt): theme-following icons, the real header atmosphere, sharp covers, playback context
**Icons follow the theme.** The bakes are frozen dark-palette hexes, so on light
themes secondary, muted and accent were simply wrong, and accent was wrong on
any theme whose accent is not #4285f4. Slint recolours at render time, which
this path cannot do — so the tint is generated once per colour into the cache
and loaded through the same Image+svg path the bakes already use. No effect, no
shader, so it cannot hit the "renders nothing on software" failure.

The sweep found the part the diagnosis had missed: "primary" was two meanings
welded together — max-contrast-on-theme-surface, and literal white for glyphs on
hosts that are dark under every theme. Remapping it globally would have painted
dark glyphs on dark scrims in fourteen places. The vocabulary is split instead,
with "primary" left as an alias so nothing changes until it is migrated
deliberately.

**The album header gradient was Slint's fallback, not its design.** Slint paints
a blurred artwork field and only falls back to the flat two-band gradient when
that image is unavailable; the port shipped the fallback. The field needs no
shader — it is a 128x128 image, so the pipeline ports verbatim: the cover down
to 8x8, back up to 128, blur, colour adjust, vignette. The 8x8 step is the look,
not an optimization; everything after it works from eight pixels of colour,
which is why it reads as atmosphere rather than as a blurred cover. It comes out
of the same decode that already produced the flat tint.

**Covers were point-sampled.** Canvas drawImage does not filter when it scales,
measured at RMSE 0.000 against a nearest-neighbour reference — a 600px cover in
a 200px cell throws away eight of every nine pixels, and the error is aliasing,
not softness. Rust now produces a derivative at the drawn device size so the
draw is 1:1 and there is no resample at all.

**The now-playing context stack.** It had no Qt counterpart: the model carried
context_kind and context_id, some builders stamped them, and nothing ever read
them back. The album path only appeared to work by coincidence, because the
glyph was hardcoded to open the album.

Plus: Discover's missing rails with real play history, Recommendations on the
integrations, queue drag reorder, and the playlist detail collage.

vicrodh a1c771c39e fix(qbz-qt): row buttons, cover triggers, light-theme contrast, flyouts, genre filter
**Track-row buttons did nothing.** Declaration order is z-order in QML, and the
row-wide MouseArea added for right-click was declared last — so it covered the
heart, cloud and menu buttons and swallowed their presses.
propagateComposedEvents cannot rescue that: a press is not a composed event,
which is why only the row's own double-click still worked.

**Covers appeared only after a scroll.** Three compounding defects, not one. The
window report fired on contentY and on model change, both of which happen while
the tab body is still hidden behind its loading flag, so the report that
mattered hit the not-visible early return and was discarded with nothing to
re-fire it. The debounce reset on every change, so a burst of mount-time reports
kept pushing its trailing edge out. And a single pending slot meant that when
two surfaces are mounted at once — the artist rail and that artist's grid — the
second overwrote the first, so one pane was never requested at all. Eviction had
the same shape: each report deleted everything outside its own array, so the two
panes deleted each other's covers.

**Latest release had no cover** because the artist page's collector skipped it,
along with Appears On and the playlists strip.

**Light themes.** The mechanism is Slint's, from 2.0.2 and issue #638: the
on-surface arm on circle actions, header-light deciding the header foreground
only when a dark backdrop is actually painted, and the circular backing behind
the track-row play glyph. Ported as specified rather than approximated. Two
icons rendered in their SVG's own colour because they pointed at the raw asset
instead of a baked tint — a sweep found the rest of that class.

**Navigation flyouts** exist, one component serving both the sidebar and the
header nav modes.

**Filter by genre and the Discover sort now work**, everywhere the control is
drawn. The genre ids were already a parameter on the discover fetch that the
port always passed empty.

vicrodh 9ab3d7db96 fix(qbz-qt): local albums route to the local view, and the detail-page parity round
**The empty album view.** Opening a local album from Library "All" landed on a
blank page. The mixed feed hands Qobuz and local albums to the SAME card, and
the card always called the catalog open — so a local id, which is a group key
or a filesystem path, went to /album/get and came back 404. It was in the
owner's log before this round as `get_album(/mnt/nas/…) returned 404`; what
changed is that clearing the stale document turned "shows the previous album"
into "shows nothing", which is how it surfaced. Routing now happens in
open_album itself, using the predicate the feed already uses to route
favourites, so every call site is covered at once instead of card by card.

**Header atmosphere.** Both detail pages get Slint's two-band gradient, tinted
from THIS page's artwork through the ported header_tint — not the now-playing
ambient triad, which is a different subject with a different algorithm.

**Artist page.** The catalog/library toggle existed but was broken: a
hand-rolled copy of the shared tab bar whose delegate walked the wrong parent
chain, so it threw on every evaluation and never took its active colours. It
now mounts the shared control. Added the JUMP TO label, the tab-strip search
with the client-side filter it drives, and the year under release-section
albums. The Network panel ran the full window height and never auto-opened; it
is bounded below the tab strip now and opens unless the content is constrained,
as Slint does. The action circles were the wrong size with the wrong glyph
colour and no overlay arm — which would have left them dark-on-dark once the
gradient landed.

**Quality in track rows.** The column rendered a bare tier; it carries the
badge now, in the one shared row component every surface mounts. playlist_qt
was the only producer not emitting the bit-depth line.

**Skeletons hand over instead of disappearing.** They cleared when the PATH
arrived, but the image still had to load and rasterize after that, so the
placeholder vanished and left an empty cell. They now wait for the image to be
ready.

**Local covers.** Most local covers ARE already the scanner's thumbnail, but
re-hashing their path produced a different filename, so each one was decoded,
resized to its own size and re-encoded into a duplicate before being shown.
That was most of the wait.

vicrodh f3a33245b2 feat(qbz-qt): staged loading, skeletons everywhere, lyrics, gestures, richer menus
**Deferred external rows.** The album page awaited the Last.fm row before
publishing anything, so the tracklist waited on an external service plus
MusicBrainz. It publishes in stages now — header and tracks first, then each
Qobuz rail as it lands, then Last.fm — with every patch merged under a
generation counter so a late reply for album A cannot paint onto album B. The
artist page was already staged this way; its views were the part still showing
bare "Loading…" text.

**Skeletons as the standard.** One control, new variants rather than new
components, mounted across the views. Its second job is the one the owner
named: cleanup. A cover that never resolves settles the placeholder once and
reveals the card's own empty state instead of shimmering forever — local albums
with no embedded art produce no artwork entry at all, so a placeholder gated
only on "not arrived yet" would never stop.

**Local artwork streams.** Fifteen seconds to first cover on a 1274-album grid
was one batch emitted after the whole window resolved. Each cover emits as it
resolves now, visible band before prefetch margin.

**Lyrics migrated.** Smooth sync instead of a 1 Hz tick, word-level karaoke
where the document carries it, the surrounding-line dimming, the controls
flyout and the translation layer the v10 backend already supported. Exactly one
row subscribes to the 30 Hz output; the timer drops to 250ms when paused or
hidden.

**Navigation by mouse and touchpad.** Side buttons and a two-finger horizontal
swipe, matching #653 — including the part that matters, which is that a swipe
over a carousel scrolls the carousel. The layer is declared first in the shell
so everything else gets first refusal.

**Context menus.** Brought to the Slint inventory, Play later included, with
right-click opening the same menu as the button everywhere. Entries whose seam
does not exist are hidden rather than shipped inert.

Two controls that rendered and no-opped are now honestly disabled: the My QBZ
nav row, which routes to a view the shell has no case for, and three sidebar
menu entries with no backing call.

The sidebar caret was never a condition bug. The row is a positioner and the
name cell's width ignored the count label, so a folder WITH content pushed the
chevron past the clip — which is why it vanished exactly when it mattered.

vicrodh d76f694781 feat(qbz-qt): close the two declared debts on the album and artist pages
The Last.fm similar-albums row exists now. The recommendation building was
already frontend-agnostic in qbz-external-reco, so this only adapts QbzCore to
its catalog trait and publishes the result; the row seeds on the album's artist
and excludes what the two Qobuz rows already show, including ids the
pre-resolution dedup misses. Resolved rows cache per album for thirty days in
the same store the Discover tab uses, so re-opening an album makes no Last.fm
or Qobuz calls, and only a non-empty result is cached — a transient failure
must not hide the row until restart. With Last.fm not connected it resolves to
nothing and makes no network call, so the rail simply never appears.

Relationship rows navigate. They carry a name rather than a catalog id, so the
click resolves through MusicBrainz first and only a CONFIRMED match opens an
artist — landing the user on a same-name musician is worse than a row that does
nothing. The role travels with the name so a match in another role is not
mistaken for this one.

vicrodh 960715c4ac feat(qbz-qt): skeleton placeholders for the heavy views
Library and Home showed grey squares that filled in unevenly, which reads as
broken rather than as loading. One shared QbzSkeleton — a card shape and a row
shape — now stands in while data is on its way, and each placeholder clears as
its own item arrives rather than all at once, so loading reads as progressive.

The animation is the part that could have undone the point of this track, so it
is capped: a bounded number of placeholders breathe, and the timer stops when
the view is not visible or the window is minimized. Not on focus loss — a
tiling desktop keeps windows visible and unfocused, which is the rule already
established for the ambient field.
