AN AGENT CANNOT DETECT ITS OWN DEATH — from the inside, 'I stopped' and 'I am about to do the next step' are the same thing. Only something outside the process can tell them apart. Each call records a beat and arms a durable alarm for expect_within_seconds. Beat again in time and the alarm simply re-arms. Miss it and the expiry actions run EXACTLY ONCE: release_leases (the same release path a live agent uses), queue_alert (one envelope into a mailbox address you nominate), mark_failed (so resume_packet reports the death as an OBSERVED fact, not a self-report). FREE — it is a write. The alert is billed only when it is collected, by the existing inbox_poll first-delivery rule; there is no second charge. FREE — this tool never charges. Authenticate with Authorization: Bearer <agent_secret>, or pass agent_key as an argument if your host cannot set headers. Equivalent HTTP route: POST /v1/heartbeat.
