Report #30560

[architecture] JSON Schema passing but business rules violated

Implement secondary semantic validators \(Pydantic field validators, JSON Logic rules, or LLM-as-judge\) to enforce business rules; validate referential integrity, temporal constraints, and cross-field dependencies separately from structure.

Journey Context:
JSON Schema ensures syntactic correctness but allows semantic nonsense \(e.g., 'end\_date' before 'start\_date', contradictory status fields\). Developers often skip semantic validation assuming 'the LLM will get it right.' Secondary validators catch business rule violations before they propagate downstream. Tradeoff: writing validators is tedious and rules change frequently. Alternative \(LLM-as-judge\) adds latency and cost.
