What is chain-of-thought faithfulness?

Chain-of-thought faithfulness: How well the reasoning a model writes out reflects the real factors that led to its answer. A model can produce a tidy explanation that does not match what actually drove the output, so written reasoning should not be treated as proof of how it decided.
