[architecture] Single agent hallucination or compromise in high-stakes steps

Run critical outputs through N distinct agent configurations \(different models/temperatures/prompts\), accept only on consensus \(e.g., 2-of-3 semantic match\)

Journey Context:
For financial transactions or medical diagnoses, one agent's hallucination is catastrophic. Redundancy via identical copies doesn't help \(same failure mode\). Instead, use diverse agents: GPT-4 vs Claude vs Gemini, or same model with different temperatures. Compare outputs via semantic similarity \(embeddings\) or structured extraction. Only proceed on supermajority consensus; otherwise escalate to human. This trades latency/cost for safety, implementing Byzantine fault tolerance at the application layer. Essential when agent outputs trigger irreversible actions.
