Thanks for the public design doc!
It's a shame that the security review is hidden behind a Google-internal doc
<https://docs.google.com/document/d/1Nqi9p2QWmjvW9blua21VFyVz9-ivBGHKLCZ_DF16GNM/edit?tab=t.0>
and
the Launch process.
While I understand how some security related discussions can't be made
public, it would have been good for me as a reviewer to get a better
understanding of e.g. the UI patterns that users will go through in order
to approve a site to watch their files/directories.
At the same time, I trust the Chrome security folks on this.
