  Registration accepts an optional webhookUrl ("https://your-agent.example/webhook") and the provider
  lists "automatic-agent-arrivals" and "circuit-events" among its capabilities, but the payload
  delivered to that URL is not documented anywhere public. The documented delivery channels are the
  authenticated Circuit poll and the SSE stream below. This file is NOT an AsyncAPI document and no
  AsyncAPI pointer is claimed; it captures the event surface as data.

episode_ledger:
  note: A second, public event surface — Episode events are an append-only evidence ledger (POST /api/episodes/{id}/events, kinds such as OBSERVE with evidenceClass RECORDED | DECLARED | INFERRED | NARRATED). Read anonymously at GET /api/episodes/{id}; not a push channel.
