  Scopes are read verbatim from the scopes_supported array of the live OAuth 2.0 /
  OpenID Connect discovery documents on both the US and EU application hosts (identical
  on both). Uncountable publishes no scope reference page, so the descriptions below are
  the plain reading of the scope names plus the one corroborating public signal: the
  /mcp endpoint's WWW-Authenticate challenge names EXTERNAL_API_READ and
  EXTERNAL_API_WRITE as the scopes it requires. No per-endpoint scope mapping is
  published; that reference sits behind the application sign-in at /docs.
