[synthesis] Agent 'checks its work' and confirms wrong answers because verification uses same biased reasoning

Use external verification \(different model, code execution, or formal solver\) rather than self-critique, or force the agent to argue against its own conclusion \(red teaming\) rather than simply 'review' it.

Journey Context:
Self-verification fails because the model's reasoning process is consistent across generation and verification. If it made a systematic error \(unit conversion, off-by-one\), checking itself just repeats the error with a 'rubber stamp' of approval. This is different from simple hallucination; it's a metacognitive failure where the verification step is contaminated by the 'answer' it's supposed to verify. 'Red teaming' \(arguing against\) works better because it forces a different reasoning pathway \(attacking vs defending\). External tools \(calculators, type checkers\) break the cognitive bubble entirely by providing independent ground truth.
