[research] LLM generates a plausible-sounding reasoning chain that does not reflect the computation that led to its answer

Do not rely on Chain-of-Thought \(CoT\) explanations as factual audit trails for \*why\* an answer was reached. If strict faithfulness is required, enforce structured, step-by-step tool use \(e.g., forcing a calculator or code execution for math\) rather than free-text reasoning.

Journey Context:
We assume CoT provides a window into the model's 'thought process'. In reality, LLMs generate the explanation \*after\* or \*in parallel\* with the answer, often confabulating reasons that sound logical but are causally disconnected from the actual statistical prediction. This is especially dangerous in high-stakes domains where the 'reasoning' is used to justify a factual claim.
