[research] Compounding factual errors in multi-step reasoning chains \(Chain-of-Thought drift\)

Implement intermediate verification steps \(tool use or code execution\) at each reasoning step rather than only validating the final output.

Journey Context:
In multi-step mathematical or logical reasoning, a single hallucinated premise \(e.g., assuming a variable state\) ruins the rest of the chain. CoT improves reasoning but doesn't prevent factual drift. Fact-checking intermediate steps via external tools \(e.g., a Python interpreter or calculator\) breaks the compounding error loop.
