Yet, in all that noise, a git bisect will still function to find when a bug was introduced.
Do the math yourself: A bug is picked up 2 week after commit. In the meantime, a good 4096+ commits have happened since. You are looking for the pathological case, at +- 12 commits.
Do you think each and every one of those are going to be "good" commits, commits that still "compile" or function. Possible, but unlikely given the insane velocity.
I mean, if you have sufficiently well developed CI, all of those commits will 100% function. That's a part of even allowing the commit to go through.
My last vibe coded project ended up with over 250 unit tests, without any prompting for it. These new models are VERY test heavy. I'm sure that's the reason why scores are so much better than they used to be.
