[architecture] Downstream agent receives out-of-domain or context-drifted output, causing it to hallucinate to fill the gaps

Implement a lightweight 'Verifier' agent or deterministic assertion layer between handoffs that checks the upstream output against a predefined rubric before passing the payload to the downstream agent.

Journey Context:
In a linear chain \(Agent A -> Agent B\), if Agent A fails to retrieve a required piece of information, Agent B often hallucinates an answer rather than admitting failure. Passing data blindly assumes the previous agent succeeded. A verifier acts as a quality gate. Tradeoff: Adding a verifier increases latency and token cost, but drastically reduces cascading hallucination errors in complex pipelines where context drift compounds exponentially.
