I did a bit of digging, and the mypy failure is ultimately from this typeshed pr: python/typeshed#12884. At that time pytest was the only one to get noticed by mypy-primer, with the same issue black is having now. Going off the fix in pytest, the mypy failure can be fixed by

But because github I can't find a good way to get these changes into this PR. As far as I can tell the only options are leaving a comment, or opening a PR against pre-commit-ci-update-config, neither of which are great.

Ahhh - I tried locally but didn't Union both the inner and outer ... I'll checkout the branch later and push a commit ... thanks!

Wat have I screwed up?

I'm still not sure how exactly the auto-format fix might work, I'm not good enough with CI, so I always manually run black on the segment of the file in question to make sure it formats correctly :)
