[research] LLM verifying its own hallucinated fact and confirming it as true

Use an independent, isolated model instance for verification, and prompt it to play a 'Devil's Advocate' role. The verifier must be given ONLY the claim and a fresh retrieval tool, not the original generation context.

Journey Context:
Self-correction via 'Did you make a mistake?' prompts often fails because the model shares the same parametric blind spots as itself \(it just re-generates the same hallucination and validates it\). Cross-examination with a separate model or an external tool breaks the confirmation bias loop, forcing a true second-look rather than a mere paraphrase of the first error.
