A two-pass compiler architecture from the 1970s is proposed as a solution to the reliability problem in LLM-generated code. In this model, Pass 1 uses an LLM to translate design specs into a structured intermediate representation (IR) — a meta-language markup — rather than directly emitting framework code. Pass 2 is a fully deterministic code generator that converts the validated IR into production-grade Angular, React, or React Native code. This separation eliminates entire categories of LLM failures like hallucinated APIs, script injection, and non-reproducible output, while preserving the LLM's strength in understanding intent and structure.
