Three Overlooked Failure Points in RAG Pipelines and How to Build a Feedback Loop

The article analyzes silent failures in Retrieval‑Augmented Generation pipelines, identifies three gaps—retrieval relevance, LLM confidence masking uncertainty, and missing fault signals—and presents a practical feedback‑loop architecture with relevance gating, post‑generation evaluation, session tracing, and user‑signal logging to make production RAG systems trustworthy.
