The question I have is what is an AI assisted contribution? For example, I still write code by hand, but I make many prototypes using AI before committing to a specific implementation. My code is clearly AI "assisted", but all of my final code is written by hand (no autocomplete either).
Banning does not imply verification. The policy is just a warning. So now you know, if they suspect that a PR is AI-generated, then there may be further consequences. I don’t think someone is going to apply a stamp on each PR.
The most egregious examples are always lazy (big diff, lengthy descriptions, weird phrasing,…). Now there’s a section in the policy to point to for the quick rejection.
No, you retain full authorship of your code regardless of how it's generated.
> My code is clearly AI "assisted"
No such thing, it's 100% your code, regardless of how it came to be.
From February to 09-24 the policy was "human in the loop". Any tool was fine as long as the contributor read the code and could answer questions about it.
