description: 'A2A Agent Card observed at /.well-known/agent-card.json on helius.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.'
