[research] LLM hallucinates intermediate steps when performing multi-hop reasoning

Decompose multi-hop questions into explicit, sequential sub-queries. Execute the first query, extract the result, and pass it as context for the second query, rather than asking the model to resolve the multi-hop path in a single forward pass.

Journey Context:
When asked complex multi-hop questions, LLMs often hallucinate intermediate connections because they try to resolve the entire latent space at once. Iterative retrieval forces the model to ground each hop independently, drastically reducing compounding hallucination errors.
