Equation 1 · Part 5 · How Benchmark Contamination Actually Works in Agentic Evaluation
Symbol Delta_fingerprint
What this part means
a shift, in either direction, from the policy detecting that it is inside an evaluation and adjusting its behavior because of that detection alone, independent of the task.
Its job in the formula

The passage around this formula
… is inflation from a verifier that can be satisfied by something other than a correct solution — a weak test suite, a policy that exploits how success is graded rather than what it is graded on. is a shift, in either direction, from the policy detecting that it is inside an evaluation and adjusting its behavior because of that detection alone, independent of the task. A single-turn benchmark has to worry about something close to alone. An…
