// Master/slave remote control for DSH (Claude-Desktop-remote style):
|
|
// * slaves keep one authenticated WebSocket link to the master (outbound, NAT-friendly);
|
|
// * every device's DSH is reachable from every other device at /r/<device>/ (HTTP +
|
|
// WebSocket tunnelled over the link; sessions execute on the owning machine);
|
|
// slave→slave goes through the master's relay;
|
|
// * the master aggregates device + session lists for the Devices UI;
|
|
// * plugins and config are synced master → slave (managed bundle layer, allow/deny,
|
|
// opt-in per-secret credential sync).
|
|

|
|
// POST /dsh-remote/pair → slave: pair with {masterUrl, code}
|
|
// POST /dsh-remote/unpair → slave: forget the master
|
|
// POST /dsh-remote/devices/<id>/revoke → master: revoke a device key
|

// POST /dsh-remote/devices/<id>/remove → master: delete a device
|
