 src/update/async-check.ts uses the existing owner-bound registry target with a bounded asynchronous child; pnpm owner discovery runs in src/update/pnpm-owner-worker.ts off the request loop. `src/update/notify.ts` writes successful results atomically and preserves a dismissal only for the same channel and version.

A 60-second shell heartbeat renews receipt time; entries expire after 180 seconds and the store retains at most 32 sessions. It is separate from the package version cache and from the updater job/ownership transaction. A proxy restart reports unknown until a bound desktop shell republishes; no update installation can be authorized by this snapshot.

+On Linux, a dashboard update worker started from the systemd user service is launched through `systemd-run --user --scope --quiet --collect` (`src/update/worker-launch.ts`), so it leaves the service cgroup before the updater stops `opencodex-proxy.service`; the default `KillMode=control-group` otherwise kills it with the proxy (#5750). The path applies only when `INVOCATION_ID` is set and a no-op scope probe succeeds; every other case keeps the plain detached spawn. `--scope` moves `systemd-run` itself into the scope and then execs the worker, so the recorded PID is the worker's (`tests/update/update-worker-launch.test.ts`).
