Most RAG Hallucinations Are Extraction Errors: Seven Patterns for a Typed Generation Contract

Enterprise Document Intelligence [Vol.1 #8ter] - Naming the RAG error correctly matters: model reads the context, so a wrong answer is an extraction error, not a hallucination. Seven typed-contract patterns keep the generation brick honest, with a decomposition rule for small models The post Most RA
