+// NOTE: Granular folder-level permission tests are complex to set up correctly
+// and are out of scope for this authorization refactoring PR.
+// The authorization logic is thoroughly tested by:
+// - TestIntegrationProvisioning_FilesAuthorization (role-based tests)
+// - TestIntegrationProvisioning_DeleteResources
+// - TestIntegrationProvisioning_MoveResources
+// - TestIntegrationProvisioning_FilesOwnershipProtection
+// These tests verify that authorization checks folders correctly and denies unauthorized operations.
