Add bounded native library models, complete grouping rails and scan progress. Bring source-aware metadata editing, media information and collection offline preflight to Qt, and repair inherited Plex album artwork without overriding healthy tokens.
cx
Add the chained genre, artist, and album browser with persistent layout and tab ordering. Reuse the shared album semantics for grouped versions and disc-aware details, enforce active source filters, and bound foreground detail work so chained searches stay responsive.
cx
Collapse repeated collection-and-contributor credits in the legacy Artists reader while retaining isolated collaborations. Preserve Unicode artist identities, resolve the collapsed row back to every family album, and use lexical QML timer ids so query coalescing remains live.
cx
Materialize source-scoped artist aggregates and FTS, then expose exact keyset pages and bounded A-Z metadata for the existing Artists rail.
Query the selected artist's albums through the indexed credit relationship with an independent bounded model, generation cancellation, artwork updates, and per-surface legacy fallback.

The port of the block Slint repeats in 27 views (NavState.restore-scope /
scroll-restore / report-scroll). A .slint file cannot hand a component a
reference to a Flickable, which is why the reference inlines it; QML can, so
controls/ScrollMemory.qml exists once and 31 containers mount it.
Two divergences from the reference, both forced by the same fact — tabs are not
history entries in this port:
1. THE SCOPE IS NAMED BY THE VIEW, not derived from the entry by a scope_for
table. Slint can derive it because its entries carry the tab
(Favorites { tab }); here an entry is a bare route id, so a derived scope
would read "library" for all five Library tabs and pour the Albums grid's
offset into whatever tab mounted. Letting the reporter name its own scope
buys tab granularity for free, and the mismatch case degrades the right way:
an unmatched scope restores NOTHING instead of restoring the wrong thing.
2. THE RESTORE RE-ASSERTS instead of firing once. A Qt item view resets
contentY to 0 whenever its model is replaced, and several pages assign their
model from a binding whose inputs arrive over the network after the mount —
the album page rebuilds listCells from three deferred rails, so it hands its
ListView a new array up to four times in its first seconds and snaps back to
the top over a restore that already ran correctly. The offset is held and
re-applied until a 2.5 s deadline, or until the user takes over (a wheel, a
drag or a flick raises `moving`, and from then the position is theirs).
Diagnostics are off by default: QT_LOGGING_RULES="qbz.nav.scroll.info=true" for
the QML half, RUST_LOG=qbz=debug for the stamp/arm half.

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.

**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.
cc
**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.

The view had roughly a folder tree and an album grid inside one 1,847-line
file. Slint's is 2,671 lines across five tabs, and the local album detail is a
routed page of its own. This closes that gap and splits the result: the view
becomes a composition root over qml/views/local/ modules, and
local_library_qt.rs becomes a narrow facade over local_* modules by concern.
Plex is wired for real. The port hardcoded the cache path to None, so the union
was local-only and Plex thumbnails were skipped. The settings store binds per
user at session activation, the album and track union includes Plex, thumbnails
resolve through the artwork path, rows carry their source badge, and the manual
re-sync is on the toolbar behind the availability gate — as in Slint.
Tabs: Albums with its quality/format/source filter popup, Tracks paginated,
Folders in both flat and two-pane tree modes, Artists as an A-Z master/detail.
Every list is windowed from the start, artwork id-keyed and evicted, because
16k tracks is exactly where the Slint build freezes.
The tree grows a real select mode with its bulk bar, the ad-hoc "ephemeral
folder" pane plays music that was never indexed, and the album page gets its
version picker — a local album with two physical copies now switches between
them without a database round-trip.
Two agents built the QML and the Rust halves in parallel and the QML called
thirty QbzLocal members that did not exist. QML resolves lazily, so each would
have been a control that renders and does nothing; a static cross-reference
caught them before a build ever ran, and they are implemented here.
Deliberately logged seams, not half-paths: add-to-playlist, add-to-mixtape and
the tag editor have no picker or modal in this port yet, and local favourites
are not wired, so those actions log rather than route a local id into the Qobuz
API. Plex playback downloads the part instead of range-streaming it, which is
Slint's own documented fallback.
