1. That rule reems to refer to posts, so I assume this comment is okay. Though I don't necessarily think that is what you were talking about.
2. Even if an AI South Quark were included in the corner of the post instead of what we ended up with in the OP, I think that is still allowed. There was obviously enough manual effort put into the end result that the one AI element is not an issue.

I believe this is how the AI rule is interpreted/enforced.

Rule 7 is intended for posts, not comments. We tend to let community voting handle comments.

Not everything that has been touched by AI is automatically trash.
