…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".

Part 8/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-07-core-provisioning. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).
Ties the pieces into a single session the user can follow: one thing happening at a time, every stage narrated, and stale work never applied late.

SessionReducer.kt— the total state machine; unhandled pairs are no-ops. Line-by-line.QuickBuildSessionManager.kt— epoch guards discard stale daemon and build results.ProxyAppBuildRunner.kt— rebaseline now relaunches the reinstalled app; not yet device-verified.Fakes.kt— completes with FakeQuickBuildHistoryStore.How this PR Was Tested
:quickbuild:core:test— the full core suite, all four slices: 65 test files (63 suites; RoomAppFixture and Fakes are fixtures, not suites), 1,102 tests per variant across all 6 variants, 0 failures, 0 errors [measured on mac]. Coverage 97.7% line / 90.3% branch.Coverage (JaCoCo at the stack tip, single run):
…quickbuild.domain.session…quickbuild.service.provision…quickbuild.service.session11 source files in the diff, all 11 measured.
Slice 4 of 4 — the core module is complete at this cut.
