[research] Hallucinations compound when answering multi-hop questions requiring combining multiple facts

Decompose multi-hop queries into independent, single-hop sub-queries. Verify the fact for each step independently before synthesizing the final answer.

Journey Context:
When a question requires combining Fact A and Fact B, if the model hallucinates Fact A, Fact B is reasoned over a false premise, guaranteeing a false conclusion. End-to-end generation for multi-hop reasoning has a compounding error rate. Decomposition isolates the failure mode to a single step, allowing early stopping or correction.
