[research] Factual errors compound in Chain-of-Thought leading to fabricated conclusions in multi-step reasoning

Decompose multi-hop queries into discrete, verifiable sub-queries. Execute retrieval/grounding for each sub-query independently before synthesizing the final answer. Do not allow the model to generate intermediate facts without external validation.

Journey Context:
Standard CoT allows errors in early steps to cascade uncontrollably \(error propagation\). A model might correctly identify a concept, hallucinate a property of it in step 2, and derive a completely false conclusion in step 3. By forcing tool-use/retrieval at each reasoning step \(e.g., ReAct or iterative RAG\), intermediate facts are anchored, breaking the compounding drift.
