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?

from TFA:

> The Foundation says we can expect Godot's contributing policy to soon include explicit rejections of AI-authored code, noting that contributors should only use AI assistance for "menial things" and must disclose its use. Additionally, the Foundation will reject any AI-generated text in human-to-human communications, saying it's "a basic principle of respect"—though it says machine translations "are still acceptable" if the original text was human-authored.

As long as your bots aren't contributing low-effort garbage in a push to give their operator some of those tasty internet brownie points you should be fine
