[architecture] Passing invalid or out-of-distribution output from Agent A to Agent B, causing B to hallucinate a fix

Implement a programmatic validator function at the agent handoff point. If validation fails, programmatically loop the error back to Agent A with a strict correction prompt, rather than passing the bad output to Agent B.

Journey Context:
When Agent B receives bad input, it often tries to 'help' by guessing, leading to compounding errors. Agent B should only do Agent B's job. The architecture must treat the A->B boundary like a microservice API contract. If the contract is violated, the producer \(Agent A\) must fix it. The tradeoff is increased latency and token consumption due to retry loops, but it strictly contains errors and prevents cascading hallucinations.
