- Added using toasts instead of update banner

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe framework adds delayed initialization for context setups. The update service prepares packages asynchronously and reports readiness based on package and preparation state. The update scenario uses toast actions for available and completed updates. The automatic-update setting replaces the auto-download setting and is included in release-dialog results. The update banner, its model, and related ready-update interfaces are removed. Priority: ➖ Normal Merge Risk: 🟠 High · up to Some users may have automatic updates re-enabled, and an in-place update may fail to install after restart. Resolve the update lifecycle and preference regressions before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new update flow can lose an existing automatic-download opt-out and allows update checks to overlap package preparation. This can re-enable background processing or disrupt an update being staged. Existing macOS signature checks remain, but completion and shutdown behavior are not fully established. Retained concerns

Fix the update-available toast text when the package is not downloaded.
showUpdateAvailableToast(res.val, false) runs when the automatic check finds an update and automatic updates are disabled. In this case, the update has not been downloaded yet. showUpdateAvailableToast always shows "%1 %2 is now ready to install." for both values of downloaded. The message therefore says the update is ready to install, but the next step is a download.
Use a separate message when downloaded is false.
Proposed fix (in `showUpdateAvailableToast`)
- const std::string msg = muse::qtrc("update", "%1 %2 is now ready to install.")
- .arg(application()->title().toQString(), QString::fromStdString(info.version)).toStdString();
+ const QString fmt = downloaded
+ ? muse::qtrc("update", "%1 %2 is now ready to install.")
+ : muse::qtrc("update", "%1 %2 is now available.");

Finalize the prepared update before dispatching quit.
AppUpdateScenario::askToCloseAppAndCompleteInstall() dispatches quit with downloadedReleasePath(), but it does not call service()->installUpdate(). The prepared path therefore does not reach finalizeUpdate() in this flow. Call installUpdate() when an in-place update is ready. Keep the package-path fallback for manual installers.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Canceling during preparation leaves m_downloadInProgress set. A new request then gets a dead Progress.
removeDownloadedRelease() calls m_updateProgress.cancel(). It does not clear m_downloadInProgress. In the preparation phase, no handler on the cancel signal clears the flag either, because Line 259 and Line 352 disconnect it. The flag is cleared only when the worker callback runs at Line 395. Unpacking a large package can take a long time.
The flag stays true during that window. A new downloadRelease() call (for example, the user opens the download dialog again) then hits the early return at Line 240-242. It returns the already-canceled m_updateProgress. When the worker finishes, the callback sees isCanceled() and returns without calling finish. AppUpdateModel::load subscribes to finished() and never receives a result. The download dialog hangs.
Clearing the flag on cancel is not enough on its own. If the flag is cleared on cancel, the old worker callback still runs m_downloadInProgress = false (Line 395) without checking which operation it belongs to. That can clear the flag while a newer preparation is still running. Fix both parts:
- Clear
m_downloadInProgresswhen preparation is canceled. - Give each preparation a generation id. Let the completion callback change state only if its id is still the current one.
Proposed fix
void AppUpdateService::prepareUpdate(const muse::io::path_t& packagePath)
{
resetPreparedUpdate();
+ const uint64_t generation = ++m_prepareGeneration;
+
+ m_updateProgress.canceled().onNotify(this, [this]() {
+ ++m_prepareGeneration;
+ m_downloadInProgress = false;
+ m_updateProgress.canceled().disconnect(this);
+ }, Asyncable::Mode::SetReplace);
...
- async::Async::call(this, [this, packagePath, prepared]() {
- m_downloadInProgress = false;
-
- if (m_updateProgress.isCanceled()) {
+ async::Async::call(this, [this, packagePath, prepared, generation]() {
+ if (generation != m_prepareGeneration || m_updateProgress.isCanceled()) {
if (prepared.ret && prepared.val != packagePath) {
fileSystem()->remove(prepared.val);
}
return;
}
+
+ m_downloadInProgress = false;
+ m_updateProgress.canceled().disconnect(this);Add uint64_t m_prepareGeneration = 0; to AppUpdateService.
Based on learnings: an async completion handler should not reset a shared in-flight flag unless the completing operation is still the current one.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert on showWithTimeout, not show, in the "no completed-update toast" tests.
showUpdateCompletedToast() calls toastService()->showWithTimeout(...). It does not call show(...). m_toastService is a NiceMock, so an unexpected showWithTimeout call passes without a failure. Assume delayedInit() shows the completion toast by mistake on a regular launch. This test still passes in that case. The DelayedInit_InstallDidNotHappen_NoCompletedUpdate test has the same problem.
Proposed fix
//! [THEN] No toast is shown
- EXPECT_CALL(*m_toastService, show(_, _, _, _, _))
- .Times(0);
+ EXPECT_CALL(*m_toastService, show(_, _, _, _, _))
