[architecture] Multi-agent pipeline suffers from the telephone game effect, where small hallucinations in early steps compound into catastrophic failures

Implement an independent 'Verifier' agent or deterministic validation step between handoffs that checks the output against the original input constraints before passing it downstream.

Journey Context:
Trusting Agent A to check its own work is insufficient due to sycophancy and lack of self-correction. A separate, isolated Verifier agent with a different system prompt \(or a deterministic rule-based check\) acts as a gatekeeper. Tradeoff: Doubles token cost and latency for the step, but prevents cascading failures which are exponentially more expensive to unwind.
