[research] A minor hallucination in an early reasoning step cascading into a completely wrong final answer

Decompose multi-hop queries into discrete, independently verified sub-queries. Do not allow the model to answer a multi-hop question in a single generation pass. Use a state machine or agentic loop where step N\+1 must be grounded in the verified output of step N.

Journey Context:
Multi-hop reasoning requires compositional generalization. If step 1 has a 5% hallucination rate and step 2 has a 5% rate, the joint probability of a correct final answer drops drastically. Standard single-pass CoT compounds these errors. Decoupling and externally verifying intermediate steps \(e.g., via tool use or retrieval\) breaks the error propagation chain.
