BETH — the Behavioral Equivalence Test Harness. Pack lays out one cell per scenario × compiled surface; you are the operator: run each prompt in a real host, paste the final response back, export the run, and judge it locally with your own keys in your own terminal. This page never asks for a credential and never talks to any server. A scorecard is one observation per surface, not a proof (ADR-0009).
