Agents inside the Care Orchestrator communicate via a JSON-RPC-style envelope. Inbound A2A messages are routed via POST /api/care-orchestrator/tasks/route.

{
  "from_agent_id": "agt_intake",
  "to_agent_id": "agt_triage",
  "context_id": "ctx_abc",
  "message": {
    "role": "assistant",
    "content": "Triage these symptoms.",
    "data": { "screeners": { "phq9": 14 } }
  },
  "auth": { "agent_token": "..." }
}

Every A2A call is logged and ties back to a workflow_id for trace continuity.
