[research] Hallucinations compound in multi-hop reasoning where intermediate steps require accurate facts

Decompose multi-hop queries into explicit, single-hop sub-queries. Verify the factual output of each step independently before passing it to the next step.

Journey Context:
When a question requires chaining facts \(e.g., 'Who is the spouse of the director of movie X?'\), an error in identifying the director propagates and amplifies, leading to entirely fabricated entities in the final answer. End-to-end generation hides these intermediate failures. Explicit decomposition and verification \(Chain-of-Verification\) breaks the error propagation chain and isolates hallucinations to a single, correctable step.
