-- Added `broadcasted` field to the base `Frame` class. This field is automatically set to `True` by `broadcast_frame()` and `broadcast_frame_instance()` to distinguish broadcasted frames from single-direction frames.
+- Added `broadcasted_sibling_id` field to the base `Frame` class. This field is automatically set by `broadcast_frame()` and `broadcast_frame_instance()` to the ID of the paired frame pushed in the opposite direction, allowing receivers to identify broadcast pairs.
