A project I was working on for a couple years until this spring started to turn like this when another contractor started committing AI work. There was a test literally called “test_imports.py” that, you know, tested that you could import every module of the project. I asked if we could just run `python __main__.py` to test that the imports worked, but he said no, we need this for big Claude-powered refactors to make sure nothing breaks.
