[synthesis] Agent validates its own incorrect output using reasoning derived from the same incorrect output, creating a self-reinforcing error spiral with increasing confidence

Implement adversarial validation: use a separate agent instance or independent verification tool to validate outputs, never the same agent that produced them. The validator must receive only the original requirements and the output—never the producer's reasoning chain.

Journey Context:
When an agent produces output in step 3 and then 'checks its work' in step 4, it typically re-derives reasoning from its own prior output rather than from original requirements. This creates a confirmation bias loop: the agent 'confirms' its error because the error is internally consistent. The agent reports high confidence because each validation step appears to corroborate the last. Self-correction prompts \('are you sure?'\) fail because the agent re-runs the same flawed logic with the same flawed premises. Only independent validation starting from original requirements breaks this loop. The tradeoff is cost \(roughly 2x agent calls\) versus reliability. This is the right call because a confidently wrong agent is more dangerous than an unverified one—it will resist external correction.
