I'm still experiencing major pre-commit issues on my local machine, and I'm not sure why the Py311 environment is failing right now, as I'm not getting any local errors.

The tests are failing for me locally for two reasons:

1. Coverage is not finding any reporting data (because the tests aren't actually testing anything).
2. Linting is failing.

IMO both things are fine for now - we're not going to merge this anyway until the application logic and tests are in place.
