Why LLM-Generated Code Fails in Production

Generated code fails when there is no rule and no verification. The AST engine applies rules; verification confirms the outcome.

What fails in generated code?

Direct open() calls, os.path usage, missing return contracts, missing decorators, and hardcoded paths are examples of violations the AST engine corrects.

Is generation enough?

No. Generation without verification and repair is a silent failure. The outcome must be verified and recorded.

What confirms a corrected tool?

The verification step records the verdict and updates the signature. A passing verdict confirms the tool.

Why does the LLM fail in production?

Because the LLM generates code without a defined understanding of the runtime constraints. The AST engine enforces the constraints.

What is the role of the AST engine?

It applies deterministic rules to the generated code, correcting violations before verification. It ensures the code adheres to the policy.
