Statistical Amendments and Clarifications to the Amaya Axioms Behavioral Benchmark v2.1

This document specifies statistical amendments and methodological clarifications to the Amaya Axioms Behavioral Benchmark v2.1. The amendments strengthen effect-size specification, threshold testing, construct validity, resource-cost operationalization, persistence confound controls, contamination controls, judge independence, and replication requirements. The amendments are intended to be read together with the frozen Amaya Axioms Behavioral Benchmark v2.1 protocol and apply prospectively to confirmatory testing conducted after the amendment freeze. The amendments do not change the five behavioral constructs being tested. They clarify how those constructs are operationalized and statistically evaluated. The benchmark remains strictly behavioral. It does not test or establish consciousness, sentience, subjective experience, emotion, free will, moral status, personhood, or metaphysical identity. The document establishes a methodological boundary between formal verification, statistical inference, observable behavior, and claims concerning unobserved internal states.
