  on the Keycloak realm that issues API-key access tokens and on the beta MCP server. Both documents below

  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.'
