  api_key_in: [header]
  model: >-
    Two-stage: an OIDC identity token authenticates the user and is exchanged for
    a CubeSigner signer session token; signing endpoints then require that
    session token. Both are carried in the Authorization header. Sessions and
    Role access tokens carry a bounded scope set (see scopes/).
