By the engineer's wit of course!

By detecting undefined behavior caused by violation these rules

Seeing how the Rust compiler isn't an LLM, it can't really work on wit.

From the POV of a programmer, how would you implement an unsafe block? What is disabled vs what's enabled?

Say you are tasked with making Miri; how do you detect violations of these rules?

Is there a "Rust compiler's rule" you can point to that's harder than avoiding UB in C or C++ in similar circumstances? They strike me as very similar beasts.
