…ate machine tying the slices together; every transition narrated Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
…ploy-throw containment Stale cancel flag: the Prebuilding stop latches proxyAppBuildCancelIssued with no teardown to clear it, so a later "Restart session" skipped the Gradle cancel -> clear the flag whenever an effect launches new session work (StartProvisioning / StartProxyAppPrebuild / RunProxyAppRebuild); covered by "a session started after a prebuild-stop still gets its Gradle build cancelled on restart". Unguarded provision-success tail: retention clear, generation adoption and watcher.start ran unguarded on a scope with no CoroutineExceptionHandler -> wrap the tail in the same try/catch -> ProvisioningFailed boundary the rebuild arm already uses; covered by "a watcher-start throw in provisioning's success tail fails the session instead of escaping". Collector-killing deploy throw: resendRetainedPayload called deploy.deploy() bare inside the init-launched reconnect collector, so one throw disabled catch-up for the process -> contain non-cancellation throwables as a failed re-send (return false, fall back to the catch-up build); covered by "a throwing re-send is contained - catch-up falls back now and stays alive for later reconnects".

📝 Walkthrough
WalkthroughChangesThe PR adds a reducer-driven Quick Build session lifecycle. It adds provisioning, live reload, proxy-app rebuild, daemon recovery, baseline management, status tones, session APIs, and extensive unit and integration coverage. Quick Build session lifecycle
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: ⚪ Minimal · up to This PR serializes Quick Build session progress, suppresses stale results, and relaunches the proxy app after rebaseline; the remaining concerns are limited to documentation accuracy and minor maintainability follow-up, with no actionable merge-blocking runtime or readiness risk.

The same rule appears three times: here, in
QuickBuildSessionManager.switchToProxyApp(Lines 856-859), and inLiveSessionFactory.executorFor(Lines 153-156). All three comments state the intent is "the same target the restart deploy uses", so the three copies must stay identical. An extension onProxyAppInfomakes that structural instead of documented.♻️ Proposed extension and call-site change
Add the extension next to
ProxyAppInfo:/** * The proxied launcher activity to relaunch this baseline with, or null so the caller * falls back to the package's default launch intent (which resolves an * `<activity-alias>` launcher). */ internal fun ProxyAppInfo.launcherProxyClass(): String? = components.firstOrNull { it.kind == ComponentKind.ACTIVITY && it.launcher }?.proxyClassThen at this call site:
- val launcherActivity = - proxyApp.components - .firstOrNull { it.kind == ComponentKind.ACTIVITY && it.launcher } - ?.proxyClass + val launcherActivity = proxyApp.launcherProxyClass()As per coding guidelines: "No duplication - and look wider than copy-paste.

| This is the authoritative rendering: every transition with a guard, drawn in full. The copies in [quickbuild/README.md](../../../../../../../../../../README.md) and [docs/pipeline.md](../../../../../../../../../../docs/pipeline.md) are deliberately simplified for orientation. | ||
|

| Arrows are labeled with the `SessionEvent` that drives them; parentheticals note the guard or a key effect. Self-loops that only run an effect (a tap that triggers a live reload, a retry that kicks off a rebuild) are shown; pure no-ops are not. |

Update the session-state diagram or soften its claim of being authoritative and complete. The current reducer includes additional transitions, especially the build-result and retry paths from Invalidated and Degraded, that are not shown and can mislead readers about supported session behavior.
