Sorry, Zach, we didn't merge this back when you submitted it and now it's decayed. I tried to merge in updates and resolve the conflicts but it looks like I failed. I think the only real thing that isn't formatting that it's doing now is adding some py311 runners, but maybe I'm missing something. Can you figure out what you want to do here?
