[research] Trusting Chain-of-Thought \(CoT\) reasoning as a faithful explanation of the model's actual decision process for factual recall

Treat CoT as a reasoning scaffold that improves accuracy, but do not rely on it to explain \*why\* the model retrieved a fact; use external attribution tools for true fact tracing.

Journey Context:
Researchers discovered that LLMs often generate post-hoc rationalizations. If a model outputs a factual error, asking it 'why?' will often result in a fabricated, plausible-sounding CoT that justifies the error, rather than revealing the true cause \(e.g., an overlapping entity in the training data\). This 'unfaithfulness' means CoT cannot be trusted as a provenance mechanism for fact-checking.
