The standard advice for building RAG pipelines is to improve your retrieval. Better embeddings. Smarter chunking. Larger context windows. That advice is incomplete. I spent three months building PRISM - a document intelligence system for legal and compliance teams. The retrieval was never the hardest part. The hardest part was keeping the model inside the boundaries of what it retrieved. This is how I solved it.
