I am happy to contribute, but I'm not sure I can sign this given that the code is AI generated due to the words "Your original works of authorship". If you're fine with it though, I will sign gladly.

[pimterry]

Yes, I think that's fine. As far as I understand it, as long as you directed the LLM manually and you've reviewed the output, it's effectively original authorship. The edge case is fully autonomous contributions (agents opening PRs with their own code without human involvement) but humans using LLMs as assistance counts as normal authorship in most places AFAICT.
