How strict is this no AI policy?

Say AI is used to identify and rewrite a single function that improves performance or fixes a bug, then the developer carefully reviews and tests it and submits a nice tight PR with all human communication.

So they don’t want that? They would just reject it?

If I’m understanding correctly, under the policy the higher performance function / bug free submission would be rejected and they could ask for a rewrite.

Should it then be rewritten from scratch, and clean room engineered so it doesn’t resemble the AI too much?
