notes: Probed /.well-known/security.txt, /openid-configuration, /oauth-authorization-server, /api-catalog
  and /ai-plugin.json on developers.gamma.app, public-api.gamma.app and gamma.app (all 404). The Gamma
  MCP server publishes RFC 9728 OAuth Protected Resource Metadata.

  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.'
