[synthesis] Agent confidently wrong for multiple consecutive steps due to self-correction confirmation bias

Prevent agents from writing their own validation tests for their own code in the same context window; use an isolated, pre-existing test suite or an adversarial agent to verify outputs.

Journey Context:
When an agent writes code and then writes a test to verify it, it operates under an echo chamber. If the agent's underlying mental model of the API is flawed, it will write code that reflects that flaw, and a test that asserts the flawed behavior. The test passes, and the agent becomes highly confident in its wrong answer. Self-correction without external ground truth just reinforces initial biases. The tradeoff is the overhead of maintaining external validation harnesses, but it breaks the cycle of confident, cascading hallucinations.
