openSUSE Tumbleweed's plasma6-nm 6.6.4 does not ship the org.kde.plasma.networkmanagement.cellular QML submodule that SignalStrengthInfo.qml imports unconditionally. Without it the MobileShell QML namespace fails to load and preview boots to a black screen.
Keep a minimal fallback module under tools/preview-stubs and install it only for local .prefix preview installs by default, with SHIFT_INSTALL_PREVIEW_QML_STUBS=AUTO/ON/OFF for explicit control. Add a CTest guard so qmldir entries stay backed by real files and the fallback remains tied to the QML import tree.
Point the mobile shell, navigation, and Waydroid KCM metadata at the Shift repository. Brand the KDED startup and APN autodetect module names and descriptions as SHIFT while keeping existing plasma-mobile plugin/library identifiers stable.
Add a guard for these metadata surfaces so upstream project URLs and translated Plasma Mobile overrides are not reintroduced.
Point homescreen and panel containment metadata at the Shift repository. Update the panel and task-panel descriptions from Plasma Mobile to SHIFT, and remove translated descriptions that would override the corrected base metadata.
Add a containment metadata guard while preserving the existing org.kde.plasma.mobile.* applet target IDs.
Update quick setting package metadata to use SHIFT-facing descriptions and repository links while preserving org.kde.plasma.quicksetting.* package IDs. Drop translated Description entries that could override the corrected base descriptions, update the Caffeine inhibition reason, and add a guard for future regressions.
Update first-run KPackage descriptions and websites so package-visible metadata points at SHIFT while keeping the existing mobileinitialstart package IDs stable. Remove localized Description entries that could override the new SHIFT-facing base descriptions. Add a CTest guard for the first-run module metadata.
Update session, AppStream, service, shell metadata, and initial setup about/defaults to use SHIFT-facing product metadata while keeping runtime package IDs and executable names stable. Install Shift AppStream metadata and remove stale upstream metainfo from existing prefixes. Add a guard for product metadata branding.
Install org.shift.icons as the look-and-feel icon theme while keeping the Plasma style on breeze-dark. Add the icon-theme coverage guard and CTest registration so shell, System Settings, KCM, and installed Plasma icon names do not silently fall back to missing Breeze-only assets.
Document the theme rules and add scoped REUSE metadata for the Phosphor-derived SVG glyphs.
Introduce shared dock height/reveal constants and use them in folio and taskpanel to keep overlay and exclusion zone aligned. Keep dock backing stationary while only content slides, and add a CTest invariant script to prevent regressions.
