[research] LLM fabricates a bridging fact when asked a multi-hop question requiring synthesizing information from multiple distinct sources

Decompose multi-hop queries into single-hop sub-queries. Execute them sequentially, passing the output of step N as context for step N\+1.

Journey Context:
LLMs struggle with multi-hop reasoning in a single forward pass. They often guess the final answer and confabulate the intermediate steps. By forcing a decomposition, each step is grounded in a specific retrieval, preventing the model from hallucinating the bridge between two disconnected concepts.
