  These are the scopes Fannie Mae's own OAuth 2.0 / OpenID Connect authorization server advertises,
  read from its published discovery document. Fannie Mae does NOT publish a scope reference page, and
  no public OpenAPI declares per-operation security requirements, so the mapping of scope to API
  operation is not public. Descriptions below marked `inferred: true` are our reading of the scope
  name, not a Fannie Mae definition — nothing here is quoted from a Fannie Mae scopes document,
  because no such document is published.
