Validating & Repairing Non-Deterministic JSON Outputs in Edge AI Pipelines

Technical 2,000+ word walkthrough on runtime JSON Schema validation, AST syntax repair, Zod integration, and fallback execution strategies for LLM API integration.

1. Mechanics of Edge JSON Output Repair

When LLMs return malformed JSON (such as unescaped quotes, trailing commas, or prepended conversational text), downstream application parsers crash. An edge output validator intercepts raw strings, strips conversational fences, and applies AST-based JSON repair algorithms before triggering application business logic.

2. Implementing TypeScript Zod Schema Validation

Enforce type safety at the application boundary using Zod runtime schemas.
