> So now I have two different black calls: in the pre-commit hook and in the CI/CD. And they must be of the same version.

What's the problem, exactly? I worked on projects which enforced precommit hooks running unit tests, and all the precommit and CICD test stages did was run the tests that were already in the repo.

Also, I don't understand what would be the problem of calling out-of-synch tests in precommit hooks and the CICD, given that precommit tests are used as a failsafe to not block the pipeline with broken commits.
