In `@desktop/e2e/_electron/__tests__/updates.spec.ts`:
- Around line 426-433: Update the expect.poll assertion reading
update-operation.json in the update test to use an explicit 30-second timeout,
while preserving the existing polling callback and “applying” expectation.
In `@desktop/e2e/_electron/fixtures.ts`:
- Around line 194-206: Update the pid === null branch in the daemon cleanup flow
to send SIGTERM directly to the parsed lockPID before calling
waitForProcessExit. Tolerate ESRCH when the process has already exited, while
preserving the existing ENOENT handling for a missing lock file and only waiting
when the PID is a valid positive safe integer.
In `@desktop/src/main.ts`:
- Line 354: Update the startup flow around startUpdateConsumer and runBootstrap
so installer handoff is gated until bootstrapFlow completes. Ensure
AppUpdateConsumer.handle cannot invoke quitAndInstall and cleanup while
runBootstrapAttempt is active, and preserve the existing bootstrap state
publishing and ProductWindow behavior after bootstrap completion.
In `@internal/cli/update_command_test.go`:
- Around line 493-498: Add a subtest for the missing local restart record in the
update command tests, leaving the local record absent so
localRestartStatusClient.GetSettingsRestartStatus reaches the remote fallback.
Configure getSettingsRestartStatusFn to return a distinct status and assert that
the remote call receives the operation ID and that the returned record matches
it, preserving the ErrRestartOperationNotFound errors.Is behavior.
In `@internal/cli/update_runtime.go`:
- Around line 76-85: Bound the retry loop in Coordinator.Run’s restart flow by
adding an absolute operation deadline or maximum retry count around
waitForSettingsRestart. Preserve retries for context.DeadlineExceeded while the
caller context remains active, but return once the configured deadline or retry
limit is reached so Run cannot continue indefinitely.
In `@internal/daemon/restart_integration_test.go`:
- Around line 259-260: Update the final restart observer wait in the test to use
an explicit bounded timer or deadline instead of relying on t.Context().Done().
Preserve the existing success path and report “restart observer did not
complete” when the deadline expires, using the surrounding restart observer
symbols to locate the change.
In `@internal/daemon/restart_relaunch.go`:
- Line 337: Reconcile canceled RestartStatusStarting operations when
waitForReady handles ctx.Done: update the startup/reaper flow around
handleReadyWaitDone so operations whose replacement is no longer live or whose
deadline has expired transition out of RestartStatusStarting, rather than
returning without invoking the existing failure path. Preserve normal Ready
handling for replacements that remain healthy.
- Around line 241-242: Add a single operation-wide readiness deadline around
both retry loops in waitForReady and waitForDaemonStart, while retaining each
loop’s existing per-window timer or pollUntil deadline. Ensure retries stop and
return the deadline error when the total ReadyTimeout budget is exhausted,
including calls using context.Background(), and do not rely on
runDaemonUpdateCoordinator to enforce it.

During quit or installer handoff, cleanup() waits for bootstrapFlow, but the product window invokes onReady without awaiting it. If shutdown starts while onReady is publishing the product state, markCleanShutdown() can remove the startup marker before that pending publication recreates it. The next launch can then treat a clean exit as an interrupted startup. Track and drain this callback, or otherwise prevent its publication from completing after clean-shutdown marking.

This test expects publications after markCleanShutdown() to leave app.json unchanged. However, AppStatePublisher.publish, setRuntime, and setOperation still persist every mutation, while markCleanShutdown() only removes the startup marker. The later publish({ state: "disconnected" }) therefore rewrites the record, so this assertion fails instead of verifying the intended shutdown guard.

What & why
Fixes #559.
A replacement daemon can migrate persisted databases long before startup finishes. Previously the restart helper's 20-second readiness deadline recorded a failure, the update observer's deadline restored the older executable, and the older executable then refused the migrated home. Desktop bootstrap could compound the outage by killing a slow child or replacing a healthy newer runtime with its older bundle.
This change makes post-swap recovery conservative: restart, health, finalization, and ambiguous interrupted-swap failures retain the replacement and its backup, archive
failed, and explain how to restart or reinstall the target release or newer. It never rewrites released migrations, restores an older executable over possibly migrated state, bypasses schema-ahead checks, or deletes user data. Pre-launch provisioning/application failure recovery remains owned by the existing atomic replacement paths.The related recovery paths now behave coherently:
startingrestart observations; malformed historical metadata is reported without blocking recovery.Stalled-but-alive behavior is deliberate: this is liveness/readiness observation, not a progress-aware watchdog. A live stalled process remains pending until readiness, exit, or caller cancellation. Periodic diagnostics include the PID. Ctrl+C releases the CLI startup mutation lock without killing the potentially migrating daemon; provisioning has already completed and the updater releases its swap lock before restart observation. The detached helper holds neither mutation lock while observing and lives until readiness, actual exit, or its own cancellation. Canceling a CLI does not cancel that helper. This preserves data at the cost of an intentionally unbounded pending wait; the operations guide explains inspecting logs/PID and recovery.

The strict QA audit passed with no blockers/warnings and clean runtime teardown.79a11d3493778928fe8a1983ce0eaf4bae6494cc: fixed Greptile’s staged-bundle integrity finding. The packaged suite first reproduced unverified execution with a marker-writing executable; after the fix both staged-recovery and tampered-bundle scenarios passed (2 tests, 13.3 seconds), including teardown. Subsequent full gates run in PR CI per the owner’s updated direction. The CLI/daemon import finding was investigated and explained in its thread as an existing composition dependency, with unchanged boundary rules and passing boundary CI.bcdfd83853d990a5450f07861fb3bab078a05854: added bootstrap observer cancellation/drain before shutdown and installer handoff, superseded restart reconciliation after real boot, remote-status fallback coverage, bounded integration-test completion, explicit E2E polling/teardown, and function documentation. Focused CLI race passed (2.391s), final daemon boot integration with race passed (6.120s), and four packaged E2Es passed under the shared lock (25.9s). CodeRabbit withdrew both global-deadline findings after reviewing the documented wait-until-ready/exit/cancel contract.

Commitlint remains enabled.Detailed QA evidence and cross-surface audit.
Limits: the runtime fault-injection fixture stages the replacement directly and does not re-test release signatures/downloads. The packaged negative scenario holds the download before installer handoff, so it verifies recovery availability without performing native installer relaunch or changing the machine launch environment. The older-app/newer-runtime policy is covered in the owning Go suites; a full older-app UI matrix is not claimed. Provider behavior is outside this lifecycle slice. The earlier web build emitted existing CSS/chunk warnings; the required local gate result is recorded separately above.
Impact
The cross-surface audit is recorded once in the QA report. CLI startup/bootstrap and update observation, daemon restart, update projection, and desktop app recovery change behavior. HTTP/UDS payloads, native tool IDs, extension/bridge contracts, hooks, config keys/defaults, and memory defaults do not change. No schema numbering or released migration bytes change, so there is no shared migration conflict with #566. User state remains in the same home and SD-013 compatibility checks remain enforced.
The public operations guide, official Compozy skill desktop reference, and affected startup/update/coherence QA scenarios co-ship. Existing Web Settings surfaces consume the same update status contracts.
