UnverifiedCitation decay monitoring needs to distinguish two phenomena: first, retrieval-layer loss, i.e. the page is no longer included in the retriever's candidate set; second, generation-layer replacement, i.e. the page is still retrieved, but the model chose other sources as citations when synthesizing the answer.74% similarUnverifiedA "ghost document" phenomenon exists: outdated process descriptions may rank higher than the latest version due to their dense keywords, while the retrieval system cannot detect document expiration.71% similarUnverified不跨页切分会对检索质量造成损失，是在检索召回与可验证性之间的权衡70% similarUnverifiedIn the cross-day text-mismatch ablation experiment, pairing texts with prices from incorrect dates caused the performance gains to disappear and forecasting performance to fall below the no-text baseline.70% similarUnverifiedEvaluating separately by corpus composition showed that loss on technical documentation was lower than on general prose, and text from MDN and WordPress was more predictable than documentation from Docker, Python, or Git68% similar
