I did notice it was red and assumed you were on it 😱

We don't require docs build because it's out of our control, I just never merge if it's red unless I know it's an upstream issue or we didn't touch docs.

Makes sense. I'll make a note not to use auto-merge in your repo for doc PRs. And yes, I'm on it!

Honestly we should probably make it required again. I just don't have the perms to do that anymore, so we'll need to reach out to robots.
