def _apply_default_scheme(value: str) -> str:
 """Applies the default git+file:// scheme if not present."""
 if isinstance(value, str) and "://" not in value:
     value = f"git+file://{value}"
 return value


class AnyUrlWithoutHost(AnyUrl):
    _constraints = UrlConstraints(host_required=False)


ConfigSourceUrl = Annotated[AnyUrlWithoutHost, BeforeValidator(_apply_default_scheme)]

@aldbr MyPy complains about code listed above because value is declared as str which makes isinstance test redundant. Pydantic manual hints that types in this case should be generic (they have Any). Then we could extend the test but this doesn't work for us, because AnyUrl scheme attribute is read-only:

elif isinstance(value, AnyUrl):
     value.scheme = "git+file" 

If Any, the validator would let in AnyUrl with any scheme which IMHO denies its purpose.
