[research] Agent fabricates the connection between two true facts during multi-hop reasoning

Decompose multi-hop queries into explicit, sequential single-hop sub-queries, grounding each step independently before synthesizing the final answer.

Journey Context:
When asked 'Who was the CEO of the company that acquired the startup founded by X?', models often know X's startup and the acquiring company, but hallucinate the acquisition link. Asking the question in one pass yields hallucinated bridges. By forcing the agent to first find the startup, then find who acquired it, then find the CEO, each hop is grounded, preventing the model from bridging gaps with hallucinations.
