[research] Model fabricates intermediate steps when performing multi-hop reasoning

Decompose multi-hop queries into explicit, sequential single-hop sub-queries. Verify the output of step N before passing it as input to step N\+1.

Journey Context:
When asked 'Who was the president of the country where the inventor of the telephone was born?', models often try to answer in one forward pass, guessing the country or the president. If they guess the country wrong, the final answer is wrong, but the reasoning looks valid. By forcing a tool-use or retrieval step for 'inventor of telephone birth country' first, the intermediate fact is grounded, preventing cascading hallucinations.
