Typing in the album track filter lost the keyboard on every keystroke. A
qt.quick.focus trace named the thief: a fresh track delegate took focus
"in scope pageFlick" right after each rebuild. In Qt 6.11 assigning a new
array to ListView.model after completion runs
QQuickItemViewPrivate::connectModel, which forces currentIndex to 0, and
updateCurrent() then focuses delegate 0 — inside the view's focus scope,
where the header's TextInput lives. `currentIndex: -1` does not survive
the assignment.
QbzArrayModel (a DelegateModel) now owns such arrays: a swap reaches the
view as remove+insert changes, which honour currentIndex -1 and keep the
rows. Because ListView re-seats inserted rows around the viewport, the
model re-expresses the viewport relative to the content origin and
restores it after layout; a page replacement calls scrollToTop(). The
album page, the kiosk album and the kiosk playlist swap their rows on it,
their ScrollMemory stores origin-relative offsets, and opening another
album resets the track filter (the box mirrors `trackQuery`).
scripts/test-array-model-qml.sh pins the behaviour (focus kept, viewport
kept, top on request) and joins the runtime gate and CI.

Integrate the Kiosk profile hardening round: 12 dedicated Kiosk views plus
22 shared opt-in hosts, shared navigation history with Back/Forward, Albums
as the default library tab, native paged Local Library (artists/tracks),
lightweight MyQBZ grid and detail, Ephemeral lifecycle, bounded lists and
artwork sized to the physical frame, static skeletons, 64px transport bar,
Settings touch reflow and a persistent Immersive exit.
Desktop keeps its prior behavior: every shared component defaults to the
desktop path and only opts into Kiosk behavior through explicit properties
(origin-relative ScrollMemory, viewport-bounded artwork requests).
Regression coverage: kiosk navigation and artwork Node tests added to the
runtime gate, scroll-origin fixtures for fixed and grouped rows, i18n
strings for all eight locales.
Verified by 750 release tests, six QML audits, Kiosk smokes at 800x480 and
1280x800 and a Desktop A/B with seven pixel-identical captures.
