Every field of both modals is a QbzSelectableText — artist, label and
musician names stay links. A copy button beside the close cross opens a
flyout: "Copy basic data" puts "{Track} - {Album} - {Artist}" (or
"{Album} - {Artist}") on the clipboard; "Copy full" formats the whole sheet
as plain text — the track's metadata, credits and copyright, or the album's
header plus the ACTIVE tab: credits per track with performers, or the
review. Album credit row heads stay plain because their click expands the
row. The two new strings ship in all eight catalogs.

Entering Discover froze the UI thread for 1.52s — not slow, frozen:
zero pixels changing anywhere in the window — where the Slint build
painted the same page, artwork included, in a single frame. Measured
frame by frame from a screen recording, with the click located at the
moment the nav flyout disappears.
`visible: false` hides an item; it does not stop QML from building it.
HomeView declared its four Discover tabs as sibling Columns gated only
on `visible:`, so every mount instantiated all four and 19 of its 28
section rails belonged to tabs nobody was looking at. Gating each body
on a Loader's `active:` cut a Home mount from 426-512ms to 182-190ms,
and the tab block itself from 364-444ms to 134-140ms.
Synchronous, deliberately: incubation is time-sliced, so `asynchronous`
spreads the same work over more frames instead of removing it.
Three more of the same class, found by auditing for it:
- SlimGrid's delegate Loader had no `active:`, so it built a full
card for the items past `total` and then hid them.
- LocalLibraryView mounted all four tab bodies, the Tracks one being
the 16K-row view.
- AlbumInfoModal built a credits row per track of the album even when
the Description tab was showing.
ContentRouter's header claimed the fix was to keep views alive across
navigation. It is not, and the references say so: Slint destroys its
view tree with `if` (AppShell.slint:426) and Tauri removes it from the
DOM (+page.svelte:6286), and Tauri even refetches from the network on
mount while still transitioning instantly. Neither gets its speed from
caching the view — both keep the mount proportional to one viewport.
The rule is the SIZE of a mount, not its lifetime. Paragraph rewritten
to say that.

The guard had its predicate backwards. `album_id.parse::<u64>()` rejected
the four-in-five Qobuz albums whose id is alphanumeric ("vy32kidwrer67",
114 of the 139 ids in the captured fixtures) while admitting local library
row ids, which are exactly what it claimed to be blocking.
A rejected open returns before touching the bridge, so the modal kept
whatever document was there: the previous album's, or — once the QML
started holding its overlay until the ids matched — an empty card. Neither
said a word above debug level, which is the whole of "only the first album
info of a session works".
The published document now stamps `albumId` with the id that was ASKED
FOR rather than the one /album/get echoed back. The QML compares those two
with exact string equality, so any divergence blanked the card silently;
a mismatch now logs instead.
Regression tests cover the four real alphanumeric ids, the barcode-shaped
minority the old guard did accept, and the local/Plex keys the guard
exists for.

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.

Opening album A's info, closing, and opening B's left A's fetch in
flight with nothing stopping it from publishing A's document over B's
loading state — the modal rendered A's credits inside B's page (smoke
catch, 2026-08-10). The carousel rows in album_qt.rs already carry the
"late replies are generation-guarded" pattern; the modal now does too:
a monotonic open counter gates every publish, open() clears the stale
document with the loading flag, and the QML overlay additionally holds
until the published document's albumId matches the requested one.

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.
