[research] Model hallucinates the final answer when chaining multiple facts \(e.g., 'Who is the spouse of the director of X?'\)

Force the model to decompose multi-hop queries into sub-queries. Execute each sub-query independently, verify the intermediate results, and only then synthesize the final answer. Do not allow the model to answer the multi-hop query in a single generation step.

Journey Context:
LLMs struggle with multi-hop reasoning because errors compound. If the model hallucinates the director of X, the subsequent search for the spouse will be based on a false premise, yielding a completely fabricated but logically coherent narrative. Sub-query decomposition isolates the failure modes and allows intermediate verification to break the error chain.
