source: live probes of /.well-known/* on fal hosts
notes: 'No /.well-known/ discovery documents are published on any fal host. The web origin (fal.ai) returns
  404 for all probed paths; the queue gateway (queue.fal.run) returns 405 (method not allowed on GET at
  those paths); the REST control-plane (rest.alpha.fal.ai) returns 404. No security.txt, OIDC, or OAuth
  authorization-server metadata is exposed. Absence is expected: fal uses static API-key authentication
  (Authorization: Key $FAL_KEY), not OAuth/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.'
