[synthesis] Multi-agent system collectively hallucinates with high confidence as agents amplify each other's small errors

Introduce an adversarial 'Verifier' or 'Red Team' agent whose sole objective is to critique and find flaws in the output of the 'Actor' agents, breaking the positive feedback loop.

Journey Context:
In multi-agent setups \(e.g., Actor-Critic\), if all agents are optimized for agreement and task completion, a small error by Agent A is interpreted literally by Agent B, who amplifies it. Agent A sees B's output and assumes it's correct, reinforcing the error. This creates a positive feedback loop of hallucination. The synthesis is that homogenous multi-agent systems are less robust than single agents; without an explicit adversarial dissenting voice, agreement becomes a bug, not a feature.
