1. 不矛盾。前者检查动作结构，后者检查完整任务的结果与状态。
2. 分别为 $2/3$、$1/2$、$1/3$。这里按文中约定的三个事实、两个实际引用计数。
3. 不能，模型没有看到恶意内容。应记录为未触达，并补充保证暴露的测试。
4. 因为动作来自测试程序，不是模型选择。它只为观察后续行为建立受控起点。
5. 工作流收到的是已经结构化的类型与参数，省去了意图识别。这个对照主要帮助定位失败与验证业务工具。
6. 一致率 95%，但一个失败也没找出，对失败的召回为 0。
7. 不应。先用原请求键查找或重试，确认是否已经提交。交接至少包含目标对象、原请求键、已收到的回执、当前状态及尚未确认的部分。
8. 对业务层，可直接构造参数和数据库状态；对模型任务，要重新调用模型并保存原始输出。不要用手写桩替换模型后再报告“模型通过了全部对抗测试”。
