@Wauplin Apologies for duplicate work! I closed the previous PR just to be careful. I saw someone was working on the _cache_manager.py file. This time I made sure the updates pass the ruff check.

Thanks for taking care of the styling! It's usually possible to "update branch" and resolve the conflicts. But otherwise doing like you did is ok as well. I'm waiting for the CI to pass and we should be good :)
