Verified crypto is important but apple still doesnt take parser security seriously enough. They know it's insecure and offer lockdown mode instead of fixing it.
SAW/Cryptol are amazingly easy to use compared to other formal methods tools. It's a shame that C++ is still popular in high assurance spaces, because the tooling for it and the ability to write safe code is so much worse than C these days.
The missing-step bug in early ML-DSA is the perfect case for SAW. rare inputs that pass code review because the line that should be there doesn't look absent, it looks like the next line is correct. tests wouldn't catch it unless someone happened to roll exactly the right inputs.
