[research] LLM hallucinates intermediate steps in multi-hop questions \(e.g., 'Where was the founder of SpaceX born?'\)

Decompose multi-hop queries into explicit, sequential sub-queries. Execute the first sub-query, extract the exact answer, and inject it as a hard fact into the prompt for the second sub-query.

Journey Context:
LLMs struggle with implicit multi-hop reasoning because they attempt to predict the final answer in a single forward pass, guessing intermediate entities. By forcing a decomposed execution graph, the model only needs single-hop reasoning at each step, drastically reducing the search space and error propagation.
