[research] Fabricating bridging entities in multi-hop reasoning questions

Decompose multi-hop questions into explicit, sequential sub-queries. Verify the output of the first hop before executing the second hop, rather than asking the model to answer the multi-hop question in a single pass.

Journey Context:
When asked a question requiring connecting two facts \(e.g., 'Who is the spouse of the director of film X?'\), LLMs often fail to retrieve the first entity accurately. Instead of halting, they hallucinate a plausible bridging entity and proceed, resulting in a confidently wrong final answer. Single-pass generation lacks the intermediate verification required for compositional factuality.
