I’m not sure I’d call most enterprise code repositories, carefully curated. I think lava flow is way more standard https://en.wikipedia.org/wiki/Lava_flow_(programming)
The problem I'm already having with LLMs (in miniature) is code/comments/docs where I don't know whether it's someone's intent or whether its un-reviewed LLM babble. That creates a continual stumbling block for figuring out whether the thing should be the way it is, or whether I'm looking at an unusually-coherent error.
Take the exact same messy pile of bytes but promise: "Everything in this made sense to a human at some point in the process", and that changes how one approaches the problem.
