The Three Failures Your AI Coding Tool Won't Tell You About

AI coding tools fail in four predictable ways: they replace your custom invariants with training-distribution averages (Prior Regression), miss the combinatorial interior of your test cases (Decision Table Blindspot), compound uncharacterized errors across sessions until bugs are no longer localizable (Generative Entropy), and pad output with agreeable noise instead of correct minimal answers (RLHF-induced verbosity). None of these are bugs. They are properties of the architecture. "We'll fine-...
