If a piece of software is in safety-critical applications these days, it is often required to have a proof of correctness.

I think you might be surprised that Linux is generally not involved in safety-critical systems. There is a whole separate ecosystem for those applications.

What do they use for that? BSD?

The ones that use an OS generally use seL4 these days.

Thanks. "OS considered harmful" is a satisfying answer, too!
