[synthesis] Agent self-correction loop approves flawed output because the judge LLM shares the same blind spots

Use a different, specialized model or deterministic rules engine for validation than the one used for generation, breaking the shared bias loop.

Journey Context:
A common pattern is to have an agent review its own work before proceeding \(e.g., reviewing generated code for bugs\). If the generating model has a blind spot about a specific library's API, the reviewing model \(often the same model or family\) will likely share that exact blind spot and approve the flawed code. The agent proceeds confidently, compounding the error into the deployment step. Self-evaluation creates a false sense of correctness; adversarial or heterogeneous evaluation is required to catch compounding logic errors.
