[architecture] Upstream agent hallucination cascading into downstream agent execution

Implement an 'LLM-as-a-judge' verifier agent that evaluates the upstream output against the original goal before passing the payload to the downstream executor agent, using a distinct, highly-instruction-tuned model.

Journey Context:
Using the same model to verify itself leads to bias and shared blind spots. Using a completely separate model \(or a strictly prompted smaller model\) as a gatekeeper breaks the echo chamber. The tradeoff is added latency and compute cost for the second inference, but it acts as a necessary firewall preventing bad data from becoming permanent state mutations downstream.
