[synthesis] Agent confidently wrong for multiple consecutive steps due to low-entropy coherent nonsense

Monitor reasoning entropy across steps; when certainty spikes abnormally fast, force temperature perturbation or external verification checkpoints.

Journey Context:
Common approaches lower temperature for 'reliability,' but this increases internally consistent wrong answers. Chain-of-Thought helps expose reasoning, but wrong CoT can be logically consistent. The synthesis is that confidence \(token probability entropy\) and correctness decorrelate in multi-step reasoning. People monitor final answer confidence but not step-wise reasoning entropy. The right call is tracking entropy trends—when the model becomes too certain too fast across multiple reasoning steps, force stochasticity or verification, as this indicates coherent hallucination patterns.
