[architecture] Accepting an agent's output as ground truth without independent verification leads to cascading failures

Implement an independent 'Evaluator' agent \(LLM-as-a-Judge\) with a strict rubric to verify the output of the 'Generator' agent before passing it to the next step in the chain.

Journey Context:
A single agent generating and validating its own work is prone to sycophancy and blind spots. In multi-agent systems, you can separate concerns: Agent A generates code, Agent B reviews it against a rubric. If B rejects it, the state routes back to A with feedback. This generator-evaluator loop drastically reduces hallucinations and ensures the output meets the contract required by Agent C. The tradeoff is doubled token cost and latency, but it is the gold standard for high-stakes output verification.
