What
A new boolean setting that requires explicit user approval before SendMessage can reach a peer Claude Code session running on a different machine via Remote Control.
Usage (in settings.json):
{
"isolatePeerMachines": true
}Details
- When the latch is engaged for a session it is persisted to the JSONL session log as
isolation-latchevents (sticky type) so resumed sessions inherit the side they were locked to. - Setting description:
Require explicit approval before SendMessage can reach a peer session on another machine via Remote Control.
Evidence
Setting schema and runtime check (search for "isolatePeerMachines" and "isolation-latch").
