[research] Generating a flawed Chain of Thought that coincidentally reaches the correct answer, reinforcing bad reasoning paths

Verify intermediate steps independently \(e.g., using a code interpreter or formal logic verifier\) rather than just checking the final output. Do not use self-consistency on the final answer alone if the reasoning path is critical.

Journey Context:
Models can 'hack' their reasoning by taking shortcuts or making lucky guesses. If an agent only validates the final code execution, it misses that the logic used to get there is brittle and won't generalize. Process reward models \(PRMs\) or step-by-step tool validation are required.
