Your RAG Gets Confidently Wrong as Memory Grows – I Built the Memory Layer That Stops It
As memory grows in RAG systems, accuracy quietly drops while confidence rises — creating a failure that most monitoring systems never detect. This article walks through a reproducible experiment showing why this happens and how a simple memory architecture fix restores reliability.
