You can now open a real shell on any connected node from the dashboard — the
daemon spawns a host PTY and streams it over the existing outbound control
channel (no inbound port, no Tailscale brokering needed).
Daemon:
- portable-pty host shell sessions: pty_open/pty_in/pty_resize/pty_close ops; a
reader thread streams base64 pty_out frames. Outbound frames now funnel through
one mpsc channel so PTY output and heartbeats interleave.
cm-api NodeHub:
- per-connection pty_sinks + sid multiplexing; open_terminal/terminal_input/
terminal_resize/terminal_close; in-memory single-use terminal tickets (the
browser WS can't carry a bearer, and the session is instance-local anyway).
- routes/nodes.rs: POST /api/nodes/{id}/terminal/ticket + GET .../terminal/ws
(bridges browser xterm <-> node PTY: binary = keystrokes, text = resize).
Frontend:
- NodeTerminal xterm modal (reuses the agent Terminal's xterm setup); a Terminal
button on each online node card opens a shell.
This proves the bidirectional streaming-over-channel mechanism the RemoteDriver
will reuse. Remaining P2: RemoteDriver + placement (run agent workloads on nodes).
