What is Heartbeat Event?
A heartbeat event is a structured JSON record every AGNT agent emits describing what it did, what tool it called, and what it decided — replayable inside the supervisor UI.
Heartbeats are the observability substrate of the fleet. Every tool call, every routing decision (including Hermes outputs), and every soul-loader update becomes a heartbeat. Because events are append-only, the supervisor can replay a session end-to-end to reproduce behaviour during debugging.
