[research] Compounding factual errors when answering multi-step questions or debugging complex call stacks

Decompose multi-hop queries into discrete, single-hop sub-queries, executing and verifying each step independently before synthesizing the final answer.

Journey Context:
LLMs struggle to maintain factual consistency across multiple reasoning steps. An early hallucination in step 1 cascades into entirely fabricated logic for step 2. End-to-end generation fails because the model cannot self-correct mid-stream. Step-by-step decomposition with external grounding at each step prevents error compounding, though it increases token cost and latency.
