A2A Agent Card observed at /.well-known/agent-card.json on urantia.dev. Grade is measured against the A2A 1.0.0 AgentCard object: 'conformant' passes every structural check, 'near-conformant' is correctly shaped but omits optional fields, 'flavored' fails a hard check and is an agent card in spirit rather than in schema. Provider-published by construction — served from the provider's own host; nothing here is derived or generated.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
