description: Results of probing the /.well-known/ discovery surface for every base host in apis.yml (baseURL)
  and the OpenAPI servers[]. Status is the HTTP code observed at fetch time. Buildkite publishes no /.well-known/
  discovery documents on any API or web host — every probed path returns 404. Absence is valid, expected
  data; nothing was saved.

  validated_on: resource (RFC 9728) / issuer (RFC 8414, OIDC)
  negative_control: one per host; a 2xx JSON object at an impossible path discards the host
note: '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.'
