The PR doesn't disclose that "an LLM did it", so maybe the project allowed a violation of their policy by mistake. I guess they could revert the commit if they happen to see the submitter's HN comment.

Dunno but a commenter already noted that some begins to say: "No LLM generated PR, but we'll accept your prompt" and another person answered he saw that too.

It makes lots of sense to me.

I've never had a one-shot prompt ever work. It's always an interactive session to eventually get to the working solution.

the policy listed is for the zig compiler. the commit in question is in a fork of a third-party library
