Measured on the built artefact: main_ui.dylib DEFINES zero and IMPORTS zero of
TokenManager, StoreRegistry, LogosAPI, LogosAPIClient and logos_core_*, out of
3410 symbols read. It links Qt and nothing else from this workspace, which
nix/symbol-gate.nix enforces across the in-process image set.
Getting there needed the last non-Qt types off the boundary: the model
properties cross as QAbstractItemModel*, catalogInstallStageChanged carries an
int rather than InstallStage::Value, and the two prebuilt AppsFilterProxy
instances are declared in QML instead of owned by MainUIBackend. That last one
removes a real inversion -- PackageCoordinator called setRequiredPackages() on
a proxy the host held a pointer to; it now emits requiredPackagesResolved() and
QML binds to the republished property.
Window resolves the plugin, qobject_casts it to IShellView, checks
hostAbiVersion() against IShellHost_abi, and calls createShell(IShellHost*).
No error-label fallback widget: that degraded to something that looked like a
working app with an empty window.
Filter proxies read role constants off host-side models and InstallEnums is
used by nine host files, so app/interfaces/ gains the contract headers both
sides compile against -- the models inherit the role structs, leaving every
AppsModel::NameRole call site unchanged. The plugin's include path is
app/interfaces only, so including a host header does not compile.
Four things only running it finds:
* Logos::DesignSystem may be linked by exactly ONE image -- both linked it
and the app aborted with "Cannot add multiple registrations for
Logos.Icons"; QML module registration is process-global
* qmltyperegistrar emits no #include for a SOURCES header given as an
absolute path outside the project
* each qt_add_qml_module is its own target and inherits no include dirs
* AUTOMOC pairs header<->cpp by same-basename-same-DIRECTORY, which the
split breaks
tst_AppManagerView.qml grows five tests for the QML binding, checked with a
negative control: breaking one assertion fails qml-tests, so they run.
