[research] Model hallucinates intermediate steps in multi-hop reasoning questions

Decompose multi-hop queries into explicit, sequential sub-queries, verifying the output of step N before prompting step N\+1.

Journey Context:
When asked a question requiring two hops \(e.g., 'Who is the spouse of the director of movie X?'\), LLMs often fail to retrieve both facts accurately and instead hallucinate a plausible bridge. End-to-end generation fails because the probability of both facts being correct in a single pass is multiplicative. Sequential decomposition forces intermediate grounding.
