note: 'Five real documents served on the primary host, including a public MCP server card at /.well-known/mcp/server-card.json
  with full tool input/output schemas. OAuth authorization-server metadata is served both on the primary
  host and on the Clerk-run auth host clerk.transcriptfetch.com (issuer). agent-card.json / agent.json
  404 — no A2A surface. api-catalog and ai-plugin.json 404 (the 404 bodies are the site''s HTML not-found
  page, recorded as misses).


  MCP-host OAuth discovery added 2026-09-19 (roadmap#321/#337): the harvest visits a provider''s primary
  hosts, and RFC 9728 protected-resource metadata lives on the MCP host, so these documents existed and
  were invisible to the scorer. Fetched live and validated on `resource`/`issuer`; one negative control
  per host.'
