[research] Compounding hallucinations across multi-step reasoning chains

Decompose multi-hop queries into discrete, verifiable sub-queries; execute retrieval/grounding at each intermediate step rather than only at the start.

Journey Context:
In multi-hop tasks, a single hallucinated intermediate step \(e.g., wrong birth country\) cascades into a completely wrong final answer, even if the final reasoning step is logically sound. Standard RAG retrieves context once, which fails if the intermediate entities are unknown. Iterative retrieval grounds each step, preventing drift.
