tests/scripts/fullscreen-toggle-tracks-real-state.txt pins the debug channel's `fullscreen toggle` deciding from the dashboard's real state rather than a private flag that `home` and a real tap left stale (rig: 14 ok). tests/test-ui-drive-rs485.sh runs offline with a fake run.sh and socat and proves ui-drive.sh --rs485-devices fails closed when the socket, pty or control socket never appears, dumps mbsim.log on failure, and kills a simulator that ignores SIGTERM. README lists both. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N3G6m9Aw5RyVY4ZowtKzEj
