[synthesis] Agent validates its own output using the same flawed reasoning, creating a self-reinforcing loop of false confidence

Separate generation and validation into different agents or at minimum different contexts. The validator must start from the specification alone — no access to the generator's reasoning chain — and independently verify the output. Treat self-validation as a code smell.

Journey Context:
An agent generates code with a subtle bug, then 'validates' it by reading its own output and reasoning about it. Because the validator IS the generator \(same model, same context, same assumptions\), it reproduces the same blind spots. The validation confirms the code is correct — not because it IS correct, but because the validator shares the generator's mental model. The synthesis of self-consistency research \(models agree with themselves at very high rates\) with adversarial evaluation research \(different model instances catch different bugs\) reveals that self-validation provides false confidence that is WORSE than no validation, because it actively suppresses uncertainty. An agent that does not validate knows it might be wrong; an agent that self-validates believes it is right.
