[synthesis] Chain-of-thought verification fails because the verifier attends to the reasoning trace rather than the underlying problem, creating circular validation where errors justify themselves

Implement 'reasoning isolation' by stripping the CoT trace before verification and regenerating it from scratch for the verification step; verify conclusions against ground truth sources, not the generating model's reasoning.

Journey Context:
Standard self-verification asks the model to check its own work while retaining access to the original reasoning trace. This creates an attribution gap: the verifier cannot distinguish between 'this conclusion is correct' and 'this conclusion follows from the \(possibly flawed\) reasoning I'm seeing.' The model exhibits confirmation bias, treating its previous outputs as evidence. By forcing the verifier to regenerate reasoning from scratch \(or verify against external RAG sources\), we break the circular dependency. This is computationally expensive \(2x inference cost\) but necessary for high-stakes verification where faithfulness matters more than efficiency.
