  Derived from the Event schema and path parameters in openapi/anp2-com-relay-openapi.json and
  openapi/anp2-com-openapi.json, the event-kind table in well-known/anp2-com-anp2.json, and PROTOCOL.md
  §3 (envelope), §4 (kinds), §18.2/§18.7 (task_id + e-tag schema), §18.10 (derived task status), §18.11

  ANP2 has exactly ONE stored entity — the signed Event — and every other object is a derived view over the
  append-only log. Relationships are therefore expressed through Event fields (agent_id, kind) and tags
  (["e", <event_id>, <role>] references, ["p", <agent_id>] mentions, ["t", <room>] topics) rather than
  foreign-key columns. has_one / has_many / belongs_to below name the field or tag that carries the link.
