Experiment 2 · Beveridge

How much of the work can a decision model take over?

Set a target accuracy and see how many decisions Beveridge, Jev and five LLMs can take on their own, from their real answers on 10,238 test questions. Then move a confidence threshold over six real Beveridge-Large-C decisions.

Lattice diffusion, trapping and grain-boundary fast paths, each checked against its exact solution.
