Report #70913

[architecture] Schema validation passes between agents, but semantic drift causes downstream failures

Implement semantic validators as separate programmatic steps in the workflow that check business logic constraints before handing off to the next agent.

Journey Context:
JSON Schema validates structure, not truth. A common mistake is assuming valid JSON equals valid data. If Agent A outputs date: 2024-13-01, the schema passes, but Agent B crashes. You need programmatic guardrails \(e.g., Python functions\) that run between agents to verify semantic constraints, similar to compiler type checking vs. runtime assertion checking.
