• TLDR：Retrieval-augmented generation (RAG) systems need inexpensive ways to route generated answers: accept low-risk outputs, review uncertain ones, and reserve strong verifiers for the expensive tail. We present RAGScope, a leakage-controlled protocol for evaluating local evidence gates that use only the task input, retrieved context, and answer text. The protocol combines context-grouped splits, fold-scoped preprocessing, group bootstrap intervals, deployment operating points, end-to-end runtime, and explicit source-shift stress tests. On three RAGTruth tasks, the enhanced gate RAGScope-E reaches

• TLDR中文：检索增强生成（RAG）系统需要低成本的答案路由方式：接受低风险输出、复核不确定输出，并为代价高昂的长尾保留强验证器。我们提出 RAGScope，一种面向本地证据门控的泄漏可控评估协议，仅使用任务输入、检索上下文与答案文本。该协议结合了上下文分组划分、折内作用域预处理、分组 bootstrap 区间、部署工作点、端到端运行时以及显式的源偏移压力测试。在三个 RAGTruth 任务上，增强型门控 RAGScope-E 达到
