A developer details a Retrieval-Augmented Generation (RAG) system designed for high-stakes domains where verifiable citations are paramount. The system's core feature is a hard refusal gate: if the confidence score for an answer falls below a set threshold, the system refuses to respond rather than providing a potentially incorrect answer. This approach ensures that every claim made by the system is directly traceable to a specific document, page, or quote, making it auditable and trustworthy for regulated environments. The implementation utilizes IBM's Docling for parsing complex PDFs, a parent-child chunking strategy for precise retrieval and contextual answers, and a swappable embedding model to optimize relevance.
