Best I can do is reply to an e-mail if someone asks for the paper, since it's not out yet. The e-mail ends with hotmail.
This gives me an impression that the paper has already been published and is available publicly for us to read.
There is a blog-style writeup here: https://fwsgonzo.medium.com/an-update-on-tinykvm-7a38518e57e...
Not as rigorous as the paper, but the gist is there.
