 - 真实跨屏证据必须能拒绝伪造的阶段、窗口位置、DPI、可见性和 `distinct_dpi`；少于两台显示器是明确环境缺口，不是通过。
 - 当前环境若所有目标显示器 DPI 相同，只验收真实跨屏路径；#31 不因该结果自动关闭，不同 DPI 与实际呈现继续保持未完成。
+- 已建立 [Windows 11 x64 隔离测试环境](../research/r2-win11-display-environment.md)，Windows 实际输出为 96/120 DPI，独立窗口两轮往返读值一致。这只完成 #131 环境基础，正式 C++/Qt 的 #31 行为与实际呈现合同仍需各自验证。
 - 任何声明支持的 Windows 显示环境都记录系统版本、监视器矩形、实际 DPI、源码/二进制身份和重复结果。不得通过修改用户系统显示设置来制造无人值守验收。
