[research] Hallucinating intermediate steps in multi-hop questions

Decompose multi-hop queries into explicit, sequential single-hop sub-queries, grounding each step with retrieval before synthesizing the final answer. Do not attempt zero-shot multi-hop generation.

Journey Context:
In multi-hop QA \(e.g., 'Where was the founder of X born?'\), models often hallucinate the intermediate bridge \(the founder\) because they try to answer the whole prompt at once. The chain of thought derails early. By forcing a retrieval step for the bridge entity first, the intermediate reasoning is grounded, preventing compounding hallucinations where a fake intermediate leads to a fake final answer.
