Report #97530

[synthesis] Planner and verifier use the same model, so they share the same hallucinations and blind spots

Use a different model family or non-LLM verifier for critical checks. Cross-model disagreement should trigger human review.

Journey Context:
Using the same model to plan and verify is cheaper than heterogeneous verification but creates correlated failure: the verifier will make the same tool-name hallucination or path assumption as the planner. True redundancy requires diverse failure modes — rule-based checks, embedding consistency, a different model family, or human-in-the-loop. The cost of diversity is justified for irreversible actions.
