The sidebar footer gains a status dot beside the spawn button: green while the
daemon answers, amber while reconnecting, red while it is gone. Hovering it
shows the release the daemon is running — commit hash and commit date.
When the events socket drops, `DaemonLink` starts polling `GET /api/info`. Past
a 1200 ms grace window an overlay blocks the UI (and swallows the app's
shortcuts) until the daemon answers again. If it comes back on a different
commit the page reloads, so a tab never drives new server code from the bundle
that was just replaced; a plain restart just unlocks.
docs/RESTART.md is the contract.
