argparse.ArgumentParser.parse_args() accepts any Iterable[str], not just Sequence[str]. The latest typeshed reflects this with the signature `def parse_args(args: Iterable[str] | None = ...) -> Namespace`. Update all main(argv:) parameters from `Sequence[str] | None` to `Iterable[str] | None` and adjust imports accordingly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
