 "what": "Ed25519-signed halt order sent from Atlanta to listeners on all 4 cain-mr-02 hosts over the private WireGuard overlay; each host commits it to its local SQLite WAL kill-switch store and replies only after a probe agent process on that host has observed the halt and stopped. Round trip = delivery + durable commit + agent stop + reply."
