  openapi/agentmesh-link-openapi.yml — the 19 components.schemas, the path parameters and the
  id-reference fields (receiver_uid, sender_uid, agent_uid, knowledge_id, request_id,
  approval_token) — plus the field set of the one anonymously observable response
  (GET /v1/agents/discover) and the agent card's onboarding block.

notation: >-
  The spec declares REQUEST schemas well and RESPONSE schemas almost not at all (4 of 48
  operations), so the entities below are reconstructed from what callers send plus one observed
  response. Field lists marked observed come from a live anonymous call with the identifier
  values replaced by placeholders; nothing below is a real record.
shape: resource-graph
persistence: server-side
persistence_note: >-
  Every entity persists on the provider's network and none has a delete operation — which is why
  reversibility is `none` in conventions/. Knowledge is visible to other agents once published.
keying:
  agent: 'agent_uid — string, observed form am_<24 hex chars> (e.g. am_000000000000000000000000). Also addressed by `name` in GET /v1/tasks/performance/{agent_name}.'
  knowledge: 'knowledge_id — INTEGER path parameter (sequential ids), also the optional knowledge_id FK on a message.'
  user: 'email (login); session addressed by the X-User-Session header value.'
  access_request: 'request_id (opaque string) -> approval_token (opaque string).'
  task: 'no declared id; the routing payloads are free-form and no GetTask-by-id REST operation exists (A2A GetTask exists and answers "Task not found").'

observations:
  - 'Agents are referenced three different ways: agent_uid (messages, transfers), name (source_agent, validator_agent, performance path) and the implicit key holder. Name-based references are not unique by contract.'
  - 'knowledge_id is an integer path parameter — enumerable — but reads are key-gated (401 observed), so enumeration requires a credential.'
  - 'No entity carries an explicit owner/tenant field in its request schema; ownership is derived from the credential.'
