Updating to v6.4.5-rc.5 and then v6.4.5 left the progress modal on "Downloading update... 10%" even though the update finished in the background. The status stream could go silent behind a proxy (Tailscale Serve, nginx buffering) and the modal only advanced on stream events. Backend: the update SSE endpoint now sends the current status on connect, writes events through one ordered writer with an explicit flush, sends a 15s heartbeat and sets X-Accel-Buffering: no. Frontend: a silence watchdog falls back to status polling, the restart phase is entered only on real restart evidence (restarting status, the server going away, or a version change) rather than a single failed poll, and the page never auto-reloads on unconfirmed completion without a pre-update version baseline to compare against.
