source: live probes of /.well-known/* on NASA API + website hosts
notes: >-
  No /.well-known discovery documents are published on any NASA host. All probes
  returned 404 (the api.nasa.gov and www.nasa.gov 404s serve the standard site
  shell). NASA uses api_key query authentication with no OAuth/OIDC surface, so
  openid-configuration / oauth-authorization-server are expected absent. Recorded
  as valid negative discovery data.
