[research] LLM fabricates the intermediate step in a multi-hop question instead of retrieving or calculating it

Force the agent to explicitly write out and verify intermediate steps using tools \(e.g., search, calculator\) before synthesizing the final answer; never allow zero-shot multi-hop reasoning.

Journey Context:
In multi-hop questions, the LLM often knows the final answer but might hallucinate the bridging entity if it doesn't perfectly recall it. It will confidently generate a plausible-sounding but factually wrong intermediate step. Decomposing the query into explicit sub-queries \(ReAct style\) and grounding each step prevents the model from bridging knowledge gaps with confabulation.
