+    parent_state_frame :
+        Optional parent frame for state tracking. When provided (e.g., for
+        CREATE's init code), state changes are tracked as a child of this
+        frame instead of the default parent determined by the message.
+        This ensures proper frame hierarchy for CREATE operations where
+        init code changes must be children of the CREATE frame.
