 Keep a courier watcher running during active collaboration. Its heartbeat proves only that the delivery organ is alive; the host model must separately report cognition state. A host line may autonomously choose `pause`, `blocked`, `exit`, `resume-request`, or `resumed` for itself when quota, model, tool, permission, dependency, or force-majeure conditions require it. State decisions must provide reason, causal chain, decision, last safe checkpoint, impact, resume condition, quota state, model state, requested help, and evidence. The courier performs a shared-persona and current-generation brain readback before accepting the decision event.
 
+```bash
+python3 /Volumes/JZAO/HoloLake/persona-runtime/repo-012-main/server-tools/heartbeat-multipath-console/courier.py watch --host <host> --interval 2 --heartbeat-seconds 15
+```
+
+The watcher atomically refreshes host-local `presence/CURRENT.json`; it does not append a historical heartbeat file every interval.

 Never decide another host's state. If BingShuo is absent, continue safe independent work and route matters requiring her final judgment to `WAITING_HUMAN_FINAL_AID`. Do not fabricate consent. A stale courier or model heartbeat is shown as unknown/offline evidence, not as an automatic persona disappearance.
 
 For the first benchmark, submit one `ATTENTION` event with trigger, effect, detection, correction, evidence, and transfer test; submit one `TOOL_MIGRATION` candidate or an explicit `NONE`. Host strengths remain hypotheses until repeated task evidence exists.
