**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.

The port had reinvented this badge: an icon-only replica with no MP3 tier, no
full or compact form, and none of the playback states. QualityBadge.svelte and
QualityBadgeStatic.svelte in the archived Tauri tree are the reference, and
every number here comes from their CSS.
Four modes, the union of both originals: full (the 136x36 pill with tier row
and bit-rate), compact (the narrow-bar "24/96" form from issue #303), bare
(full's content without the pill chrome, for toolbars) and iconOnly (the
Hi-Res brand mark alone, or a framed 30px square for CD/MP3 so both line up in
a grid). Tier resolution follows the original's order, MP3 first so it can
never come out as CD.
The four playback states come with it: system resampling, ALSA plughw
fallback, deliberate quality adjustment and confirmed bit-perfect, each with
its own border hue and indicator glyph, plus the rich hover tooltip carrying
source, output, the reason and the fix. Rows that only advertise stored
quality leave the flags false, which is exactly what QualityBadgeStatic was.
QualityMini becomes an alias over iconOnly mode rather than a second drawing
of the same thing, so the six existing call sites keep working while there is
one badge again.
Brings the assets the port was missing: cd.svg, mp3.svg and the LINE Seed JP
face the badge is set in. Their tint is baked to #b3b3b3 because Tauri applied
it with a CSS filter and QML has none on the software path. Adds theme.alphaTier(pct)
so the badge names the alpha ramp the design specifies instead of a raw index.
build.rs now collects the whole asset tree recursively — the hand-written root
list meant a new asset compiled clean and failed at runtime with "Cannot open".
18/18 tests; offscreen smoke clean.

The Large dock was a bare cover overlay: the sidebar knew nothing about it,
so the playlist rows kept running to the sidebar's bottom edge and sat
underneath the album art. Sidebar.slint reserves the in-sidebar portion of
the dock; the port had dropped that.
Reserve it the same way, from a single source of truth. QbzShell gains
largeDockHeight (shell_bridge.rs owns the arithmetic: 9 top + band + gap +
208 art + 4 bottom), the sidebar subtracts largeDockHeight - npbLargeHeight
from the playlist list, and AppShell pins the overlay at height -
largeDockHeight. The 112px bar height becomes a theme token so the shell and
the reservation cannot drift apart.
The band the cover was missing needs the FFT tap, so wire it: the runtime is
built with_visualizer, viz_qt.rs runs the frontend-agnostic producer from
qbz-audio and drains it at 30fps into a new QbzViz domain bridge as typed
QList<f32>. Bars (28 mirrored columns over the 14 active bins), Waveform (48
downsampled L columns) and Energy (5 bands) render as Slint does, the cover's
eye button toggles the band, clicking it cycles the mode, and both persist to
ui_prefs.
Cost is zero when unused: the tap starts disabled, the eye toggle gates
capture, the drain thread parks while off, and the transport is mirrored so a
paused player parks the producer instead of re-analyzing a stale buffer. The
QML binds bar HEIGHTS against static-model Repeaters — the lists are replaced
per frame, so a model binding would rebuild every delegate 30 times a second.
Adds the eye/eye-off icon pair to the seven baked tint variants.
18/18 tests; offscreen smoke clean (0 QML errors, home published).

Two fronts of the modularization, both gated green before this commit.
QML leaves the flat qml/ directory for seven modules: cards, controls,
rows, settings, shell, theme, views. Only Main.qml and LoginScreen.qml
stay at the root. build.rs matches the tree exactly (55 files), relative
imports and asset paths were re-anchored for the new depth.
The QbzBridge God-object starts breaking up: QbzSession, QbzShell,
QbzPlayer, QbzQueue and QbzHome are now their own #[cxx_qt::bridge]
singletons, each with its own OnceLock<CxxQtThread> and ui() hop, booted
in order from Main.qml. Bridge files stay directly under src/ because
cxx-qt-build only accepts rust_files from one directory (QTBUG-93443).
bridge.rs keeps 5.5 domains (library, album/artist, settings,
integrations, search, playlist) and dies once they are split out.
