[research] Agent answers intermediate sub-questions correctly but fails to synthesize them, yielding a wrong final answer

Decompose multi-hop tasks into explicit state-machine steps. Force the agent to write intermediate answers to a structured scratchpad, and explicitly pass only the verified scratchpad outputs \(not the raw context\) into the final synthesis prompt.

Journey Context:
LLMs struggle with multi-hop reasoning due to attention dilution. If asked to reason A->B->C in one pass, the model might hallucinate the connection between B and C even if B was correct. By isolating the extraction of B and feeding it deterministically into the prompt for C, you prevent the model from re-hallucinating B during the synthesis of C.
