Earlier quoted context omitted.
If you sign off the code and put your expertise and reputation behind it, AI becomes just an advanced autocomplete tool and, as such, should not count in “no AI” rules. It’s ok to use it, if that enables you to work.
this sounds reasonable, but in practice people will simply sign off on anything without having thoroughly reviewed it. I agree with you that there's a huge distinction between code that a person understands as thoroughly as if they wrote it, and vibecoded stuff that no person actually understands. but actually doing something practical with that distinction is a difficult problem to solve.
Unless the code is explicitly signed by AI as auto-commit, you cannot really tell if it was reviewed by human. So it essentially becomes a task of detecting specific AI code smell, which is barely noticeable in code reviewed by an experienced engineer. Very subjective, probably does not make sense at all.
