• The docstring for insert_once documents a return value (":return: Dictionary with clean weakref"), but the function mutates some_dict in place and returns None. Please adjust the docstring (and/or add an explicit -> None) so callers don’t assume there is a return value.

def insert_once[K](some_dict: dict[K, ReferenceType], key: K, value):
    """
    Check if the reference to an Entity with uuid is already in use.

    :param some_dict: Dictionary of UUID keys and weakref values.
