[synthesis] Agent's own verification step confirms its wrong answer

Use independent verifiers, not the same model wearing a 'check' hat. If you must use the same model, perturb the input \(rephrase, remove context\) and require consistent answers across multiple independent runs.

Journey Context:
Research on LLM self-evaluation shows it is weak because the verifier shares the same biases and context as the generator. The 'let me check my work' pattern in agents is mostly theater. Yet most agent frameworks implement exactly this. The cross-source insight: sycophancy plus shared weights means self-check fails precisely when you need it most. An external verifier or ensemble is the only robust path.
