[architecture] Unverified agent output corrupts the state of downstream agents in a pipeline

Insert a lightweight verifier agent or deterministic validation step between producer and consumer agents to check output against predefined criteria before committing to shared state.

Journey Context:
Developers often trust the output of Agent A because the prompt was good. But LLMs are stochastic. A verifier agent acts as a quality gate. Tradeoff: adds latency and token cost \(extra LLM call\). Deterministic checks \(regex, schema\) are faster but less flexible; LLM verifiers catch semantic errors but can also hallucinate. Best used for critical transitions.
