Six live tabs (All/Tracks/Albums/Artists/Playlists/Labels) with real
count badges, paged favorites/playlists/purchases loaders, library_all
merge semantics, heart routing (Qobuz API vs local store —
LocalFavoritesService now initialized at session entry), sort popup
with direction carets, grid/list toggle with natively windowed
GridView/ListView delegates, id-keyed artwork via signal with hand-
rolled eviction. Perf marks on the owner's account: 344 items, fetch
wall 2.7-3.4s (97% network, sequential), map+merge ~11ms, JSON
serialize 10ms, QML parse 7ms (~20us/item => ~140ms at the 2200-item
reference scale), RSS +29MB after publish.

Album-card click plays the album: get_album -> QueueTrack vec ->
set_queue -> play_track_resolved (tier walk stays in the core). 1 Hz
poll publishes position/meta/quality into the NowPlaying model; end-of-
track edge auto-advances with meta refresh (traced live: 24-bit/48kHz
CMAF stream, position advancing, track 2/3 transitions). Transport
invokables rewired to real core calls; queue panel shows NOW PLAYING +
numbered UP NEXT from get_queue_state. Public QbzCore API proved
sufficient — protected audio/player crates untouched. Named gaps:
no mute API, no playback event stream, auto-advance/prefetch semantics
remain frontend glue (~150 lines every UI must port).

HeaderBar (42px, sidebar cycle, back/forward, centered search replica,
offline badge + flyout, app menu), three-state Sidebar (open 240 / mini
64 / closed 0, 160ms animation, nav rows with exact msgids), NowPlaying
bar SMALL (3px three-color seekbar, art+title+time left, transport
center, quality/volume/queue-toggle right, exact empty state), Queue
panel (300px animated column, Queue/History tabs, exact empty states).
Nav history stack + NowPlayingModel with empty-state defaults behind
new bridge properties/invokables (transport log-and-noop until
playback lands). Icons as pre-baked tinted SVG variants (ColorOverlay
is broken on the software path); Inter fonts bundled; full dark theme
tokens ported from the Slint foundation files.
km
QbzBridge QML singleton (12 properties, 8 invokables) driven by tokio
tasks via CxxQtThread. Port of auth.rs (browser OAuth loopback listener
with qbzd-style nonce, 180s timeout, cancel via JoinHandle abort,
scoped offline-gate lift for cold bundle init, D1 token-keep on network
failure / clear on explicit rejection, D4 subscription grace marks).
OfflineModeEngine + ConnectivityActor started at boot with live watch
forwarding (connectivity/captive portal/recovery banner/has-previous-
session). Boot: splash -> silent token restore -> shell | login.
Start-offline enters the guest profile. LoginScreen.qml is a faithful
port with exact msgids routed through qbz-i18n. 5 unit tests green.
km
New qbz-qt bin crate (cxx-qt 0.7 + QML) as the only default workspace
member in this worktree, so plain cargo build produces just the Qt
binary. Gate verified against system Qt 6.11.1 (codegen, moc,
qmltyperegistrar, qrc load, offscreen run all green).
