[research] Model hallucinates intermediate entities when performing multi-hop reasoning

Decompose multi-hop queries into explicit, sequential sub-queries. Force the model to resolve and verify the first hop before asking the second hop.

Journey Context:
Standard Chain-of-Thought prompting allows the model to generate the entire chain at once. If the model doesn't know the first hop, it will hallucinate an entity to complete the logical structure, leading to a confident but factually ungrounded final answer. Sequential, grounded retrieval breaks the error propagation chain.
