[research] LLM fabricating intermediate steps in multi-hop reasoning chains

Decompose multi-hop queries into explicit, sequential sub-queries. Execute and verify each sub-query independently before synthesizing the final answer.

Journey Context:
End-to-end generation for multi-hop questions \(e.g., 'Where was the wife of the 8th US president born?'\) often fails because the model hallucinates an intermediate entity. Step-by-step decomposition with explicit retrieval/verification at each step forces grounding and breaks the compositionality gap.
