A recent production incident revealed that seemingly poor AI model performance was actually caused by a retrieval failure. Users reported incomplete answers, leading the team to initially suspect the model itself. However, prompt testing yielded no improvements, and further investigation into retrieval traces showed that relevant documents were consistently missing from the model's context. The root cause was a subtle ranking change in the retrieval system that demoted important documents, highlighting the need for quality monitoring beyond basic availability checks in AI systems. AI
