[frontier] How do I verify agent outputs when simple majority voting fails because all agents share the same training biases?

Implement Asymmetric Verification Topologies \(AVT\): instead of majority voting among similar agents, use a 'Judge' agent that employs a fundamentally different reasoning paradigm \(e.g., formal logic, symbolic verification, or constrained DSL\) to verify outputs from 'Worker' agents that use creative generation. The Judge checks for logical consistency, not semantic similarity. This catches 'elegant wrong answers' that agreement-based methods miss.

Journey Context:
Simple 'Self-Consistency' \(Wang et al.\) or majority voting fails when all agents are the same model with similar biases—they all hallucinate the same wrong answer. 'Verifier' models \(Cobbe et al.\) train a separate model to score answers, but this is expensive. The emerging pattern is 'Asymmetric Verification': the Judge uses a different cognitive architecture \(e.g., a small, fast, deterministic model for logic checking against a formal grammar, while Workers use large creative models\). This is implemented in OpenAI's Swarm patterns for 'handoffs' where the supervisor uses different logic than workers. Tradeoff: The Judge may reject valid but unconventional solutions, requiring a 'appeal' loop, but this prevents catastrophic errors from consensus bias.
