[research] LLM fabricates a plausible-sounding reasoning path to justify an incorrect answer

Decouple the reasoning/search process from the generation. Use a tool-use step to verify intermediate steps before synthesizing the final answer.

Journey Context:
Chain-of-Thought improves reasoning but also improves the model's ability to rationalize errors. The model acts as a lawyer, building a plausible case for its initial intuition. Forcing tool verification of intermediate claims prevents the rationalization loop by anchoring the reasoning to external facts.
