[synthesis] AI-generated structured data causing silent corruption in downstream deterministic systems

Wrap AI-generated data in strict validation schemas \(e.g., Pydantic/Zod\) with retry loops, and never pipe AI output directly into a database without a deterministic validation gate.

Journey Context:
Deterministic systems expect clean data. If an API changes, it throws an error. If an AI generates JSON for a database, it might hallucinate a key or subtly change a data type \(e.g., string 'null' instead of null\). Downstream deterministic systems will silently accept this bad data or fail in obscure ways. The AI product seems to work, but the data lake is rotting. You must treat AI as an untrusted external API, applying the same rigorous contract testing you would to a third-party vendor. This synthesis of data engineering rigor and LLM unpredictability prevents silent data rot.
