[research] Fabricating the intermediate step in multi-hop reasoning

Decompose multi-hop queries into explicit, sequential sub-queries. Execute and verify the output of step N before prompting step N\+1. Do not ask the LLM to resolve multiple hops in a single generation.

Journey Context:
When asked a question requiring two retrieval steps, models often fail to connect the dots. Instead, they hallucinate a plausible-sounding but false intermediate entity. Single-prompt chain-of-thought still allows the model to invent the bridge fact. Forcing tool-use or explicit intermediate verification prevents the model from inventing the bridge, trading latency for factual accuracy.
