A couple of previous comments, both of which point to the related paper, which is at https://arxiv.org/abs/2003.10554.

Could this be straightforwardly extended to validating correctness of filesystems?

I'm thinking of the case of developing a FUSE-based filesystem -- it'd be nice to have a test suite you can run that guarantees you haven't broken your filesystem's consistency.

Or are there already tools for this that every budding filesystem developer should look to?

Thanks - we've switched the URL to that from https://aphyr.com/media/talks/2021/vldb.mp4, which is not responding at the moment and is presumably a video.

502, maybe needs some scaling first

They should try MongoDB, it's web-scale.
