[research] Error Propagation in Chain-of-Thought Factuality

Implement step-by-step verification. After each step of the CoT, run a lightweight fact-checking pass \(either via an external retrieval call or a separate model instance\) to validate the premise before allowing the generation to continue to the next step.

Journey Context:
CoT improves reasoning but exacerbates hallucination propagation. If step 1 is a hallucination, step 2 will confidently build upon it \(evaluated in FActScore\). This is because autoregressive models treat previously generated tokens as ground truth. Breaking the generation into verifiable chunks prevents error accumulation.
