The single shared mesh is replaced by per-session rooms. Visit /
and the server mints a random 8-hex-char id, redirects to /r/<id>.
That URL IS the session — share the link (or scan the QR code now
shown on the page) on another device to join the same room.
Bus is now sharded per room. Rooms are created implicitly on first
subscribe and GC'd 5 minutes after the last subscriber leaves. No
accounts, no persistence, no server-side state beyond the in-memory
bus map.
Server:
- New endpoints: /, /r/<id>, /api/send?room=, /api/stream?room=
- Room manager with lazy creation + idle GC
- Metrics now labelled by room
- New gauge tether_active_rooms
Client (Go):
- -room flag (accepts bare id OR full /r/<id> URL — paste-friendly)
- All API calls now scope to the room
- The always-on ct210-rtc-peer systemd unit is disabled — sessions
are user-initiated; the user runs tether-client with -room when
they want their laptop in a particular session
Browser (HTML):
- Reads room from /r/<id> path
- Shows QR code + URL + "copy link" button at top
- "+ new session" link in header to start a fresh room
