[synthesis] Overconfident hallucinations persisting across multiple consecutive reasoning steps

Enforce explicit uncertainty quantification at each reasoning step with mandatory confidence thresholds and divergence detection between parallel reasoning paths.

Journey Context:
LLMs generate plausible-sounding intermediate reasoning steps that are factually wrong but stated with high confidence. Without external validation, these errors compound across multiple steps \(e.g., wrong math intermediate leads to wrong final answer\). Standard chain-of-thought doesn't prevent confident errors. The solution is requiring explicit confidence scores \(0.0-1.0\) at each step, and if confidence < 0.8, trigger tool use or retrieval augmentation. Additionally, run multiple reasoning paths \(self-consistency\) in parallel and check for divergence—if two valid reasoning paths disagree, the model is hallucinating and needs to reconsider.
