Report #48683

[architecture] Single agent hallucination passes to downstream agents undetected due to lack of verification

Implement dual execution \(two independent agent instances with different seeds/models\) with output comparison; use semantic diff \(cosine similarity of embeddings > 0.95 threshold\) or structural equivalence before passing to next stage; mismatches trigger tie-breaker or human review.

Journey Context:
Redundancy is expensive but necessary for critical paths. Don't compare raw strings—use embedding cosine similarity or structured data diff \(JSON diff\) to catch semantic equivalence despite lexical variation. Mismatches shouldn't auto-resolve; they should trigger a third 'judge' agent or human review to prevent false positives from cascading.
