I think the typer will complain with this. I see you didn't run pre-commit hooks

We do not want to have features that are based on uncommented lines of code. Could you remove this block?

As we do not pretend to be resilient to a wrongly formed static, I think I would rather have a mucher simpler implementation, closer to the original, simply adding before the serving:
assert (Path(static_path) / 'index.html').is_file(), "index.html missing in static folder."

I, ThewsyRum, confirm that I have read and understood the terms of the CLA of Kyutai-labs, as outlined in the repository's CONTRIBUTING.md, and I agree to be bound by these terms.
Previously, calling extractall to unpack files from a tar archive didn't properly check the file paths, which could allow files to be extracted outside the intended directory.
tar.extractall(path=dist_tgz.parent)Input from a command line argument is passed directly to aiohttp.web.FileResponse as a path. This could create a Path Traversal vulnerability, enabling an attacker to read arbitrary files on the server.
return web.FileResponse(os.path.join(static_path, "index.html"))
