[research] Compounding hallucinations across multi-step reasoning chains
Decompose multi-hop queries into discrete, verifiable sub-queries. Execute retrieval/grounding for each sub-step independently before synthesizing the final answer. Do not ask the LLM to answer a multi-hop question in a single generation step.
Journey Context:
A single hallucinated premise in step 1 cascades into entirely fabricated conclusions by step 3. End-to-end generation lacks intermediate grounding. While chaining sub-queries increases latency and token cost, it localizes errors and allows the agent to halt or re-retrieve if a sub-step lacks evidence.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
