A new reliability protocol (arXiv:2606.07783) tests RAG on factoid questions the model already answers correctly without retrieval, then injects clean, misleading, and mixed evidence to measure when retrieved content overrides correct internal knowledge. It introduces a parametric-override rate to quantify how strongly poisoned context flips outputs. Before you ship a RAG system, inject plausible-but-false passages and measure how often your retriever's bad data beats the model's good knowledge. If you've never measured this, you don't know how poisonable your pipeline is.
