scope_model:
  granularity: coarse — identity scopes only
  note: 'CMP publishes exactly three scopes and they are the OIDC identity trio: openid, profile and offline_access.
    NONE of them scopes API capability. There is no read vs write scope, no per-resource scope (library, tasks,
    campaigns, settings), and the clientCredentials flow declares an EMPTY scopes map. Authorization is therefore
    decided entirely by the CMP organization permissions of the user or app, not by the token scope — which means
    a consent screen cannot tell a user what an app will be able to do, and an agent cannot request least privilege.
    The docs confirm all three must be sent, space-delimited, to the authorization endpoint.'
  documented_requirement: All three scopes must be passed to the authorization endpoint, delimited by a single space.
