Rosetta 2 purely AOT? Where did you get that idea from?

It certainly still does some JIT/interpretation at runtime but it does indeed translate the executable upon first launch.^1 I can’t imagine how it would be able to fully translate a browser JavaScript engine that’s doing its own JIT, for example.

Just like the original Rosetta it does indeed cache translations as well as support JIT and other forms of dynamic translation.

Exactly. It does AOT, but certainly not exclusively.
