- anki._backend stores the protobuf files and rsbackend.py code - pylib modules import protobuf messages directly from the _pb2 files, and explicitly export any will be returned or consumed by public pylib functions, so that calling code can import from pylib - the "rsbackend" no longer imports and re-exports protobuf messages - pylib can just consume them directly. - move errors to errors.py Still todo: - rsbridge - finishing the work on rsbackend, and check what we need to add back to the original file location to avoid breaking add-ons
