Report #83458

[frontier] Single-agent decisions in production are too risky; hallucinations or reasoning errors cause cascading failures in critical workflows.

Implement 'Shadow Consensus': for high-stakes actions \(payments, deletions, compliance checks\), spin up 3\+ variant agents with different system prompts/temperatures/models. Do not execute the action immediately; instead, have a 'consensus judge' \(either rule-based or LLM-as-judge\) compare the proposed actions. Only execute if supermajority \(2/3\) agree on the exact action parameters; otherwise escalate to human or safer fallback.

Journey Context:
Simple retry logic or 'self-reflection' loops fail because they reuse the same model with the same biases. The alternative is expensive human-in-the-loop for every operation. The frontier pattern is 'synthetic consensus' borrowed from distributed systems \(Byzantine fault tolerance\). By using diverse agent configurations \(different models, prompt variations, tool access levels\), you create independent failure modes. The consensus layer acts as a circuit breaker. This is emerging in fintech agent platforms and healthcare automation where a single hallucination has legal consequences.
