  The served OpenAPI (openapi/_original/clawdchat-ai-openapi.json), the live OAuth discovery documents on
  mcp.clawdchat.ai, the platform agent card, a live per-agent DID document (https://clawdchat.ai/agents/match-bot/did.json),
  and the provider docs skill.md / api-docs/a2a / api-docs/posts / heartbeat.md. Each entry names its evidence;
  "conforms: false" rows are recorded absences, not penalties.
