Making LLM Non-Critical: How Deterministic-First Design Transforms CI Reliability

The article demonstrates a critical pattern for safely integrating LLMs into production systems: keep the LLM advisory, never critical. By layering a deterministic classifier as the sole decision-maker and reducing Groq to comment-only summary generation, the system eliminates LLM-related failures (timeouts, hallucinations, quota errors) from the CI pipeline. This approach reveals why teams can confidently replace live systems without transition periods when they prioritize deterministic guarantees over LLM sophistication.
