Report #38019

[architecture] Single agent hallucination accepted as ground truth without verification

Implement dual verification \(Byzantine fault tolerance light\): primary agent generates output, secondary validator agent checks consistency against source documents or constraints; reject on mismatch or low consistency score

Journey Context:
Single-agent systems have no error detection mechanism. Common mistake: assuming LLM consistency or using simple regex validation that misses semantic errors. Alternatives: n-way consensus \(high cost, latency\). Dual verification \(similar to BFT with f=1\) catches hallucinations at boundaries without requiring full consensus. Tradeoff: doubled latency and cost, acceptable for high-stakes outputs where error cost exceeds compute cost.
