If you are interested in a more nuanced take on what makes unsafe Rust both valuable and difficult, check out my blog post on the Oxide blog: https://oxide.computer/blog/iddqd-unsafe
I directly tackle the concerns you mentioned, and as a followup I'm actually working on formally verifying the library as well (I've had some success and will publish an update regarding this).
Ooh, cooll to hear you got some uptake on the call for formal methods help! Or did you end up figuring it out on your own? Either way, looking forward to the followup!
Mostly chatted with some people and figured it out with their help.

I'm a huge fan of Rust! I like to think my writing makes the Rust community better more than it annoys people :)
