+// AFTER a successful authentication, which reads as a broken login rather than a policy decision.
+// The scope mapping now answers `abs_groups: ["user"]` for every signer and reserves `admin` for
+// `audiobookshelf_admins`, so the IdP is the only gate to the library and onboarding a listener
+// is exactly "create the account".
+//
+// This is the counterpart to 23-: that spec proves the admin escalation, this one proves the
+// DEFAULT grant, from an identity in neither group. Against the old mapping it is red — ABS
