更新说明 本次上传补充了案例 8.1 中代理实验的现实载体定义。 上一版本中,代理实验仅在方法论层面被引用,未明确其对应的具体执行行为,导致实验定义存在结构性缺口。本次修订对该遗漏进行了补全,不涉及实验设计、实验结果或结论的任何变更。 Update Note This upload adds an explicit definition of the real-world carrier for the proxy experiment in Case 8.1. In the previous version, the proxy experiment was referenced only at the methodological level, without specifying its concrete execution behaviour, resulting in a structural gap in the experiment definition. This revision addresses that omission without altering the experiment design, results, or conclusions.
