Evidence-backed facts

  1. The A2A Registry submission flow accepts a website, ANS, or GitHub URL and scans supported A2A, MCP, OpenAI Plugin, GoDaddy ANS, or agent-card.json metadata to discover agent details. informative
  2. The Registry describes domain verification as its authenticity mechanism and separately describes discovery through DNS resolution and the registry; verification and discoverability are therefore distinct evidence states. informative
  3. Registration, directory listing, domain verification, agent connection, and transaction are separate lifecycle events in the Registry's own product flow and should not be counted as interchangeable outcomes. informative
  4. A successful scan or listing proves metadata discovery only; citations, successful protocol calls, repeat consumers, and completed transactions require separate event or log evidence. informative
