+2026-09-10：0.4.0 改为 HDC 持续 JPEG 推送，修复投屏残留会话误报占用及重连失败。0.3.2 的逐张截图链路为 696、803、802 ms，约 1.3 fps；新版本的动态帧率仍须独立测量。
 
 官方 `xdevice-devicetest` 6.1.0.210 的 `uitest_agent_v1.2.2.so` 已在 HUAWEI Pura 70 Ultra 的商业系统上成功加载。独立探针收到真实 JPEG、屏幕尺寸 1260 × 2844，并成功调用尺寸、旋转和唤醒接口。设备端文件为 600245 字节，未改动签名原件。没有安装 HAP，也没有账号或系统共享确认步骤。
 
-探测期间手机主要处于锁屏或静止状态。黑色首帧、短暂变化及收包时间不能证明动态帧率或端到端延迟达标。接入生产后端时手机变为 Offline，后端的完整真机连通、持续动态画面、输入及重连仍待验收。自动化替身测试不替代这项验收。完整自动化检查通过 85 项：47 项原生、32 项 UI/格式/坐标、6 项 USB 桥接与底座协议检查。
+生产后端已在同一台真机上连续通过三轮“开始 → 接收并解码 → 停止 → 再次开始”，全程未拔 USB，每轮均确认 `pidof uitest` 为空、`fport ls` 无残留。每轮收到 2–3 张独立画面，也验证了静止画面返回 unchanged 的行为。独立探针另收到可查看的实际手机内容；这项连通/重连检查没有发送输入，不能作为动态帧率、跟手程度或端到端延迟达标的证据。
+
+本次错误来自插件自身的残留 `trove-screen-*.so` 会话。手机的普通 `kill` 返回 `Permission denied`，旧代码忽略失败并把任意 UITest 进程视作其他工具。官方 xdevice 的清理使用 `kill -9`；当前手机实测接受该命令。修复会检查完整命令行身份，只清理本插件代理并确认进程退出；显式停止时清理失败会返回错误。其他工具的代理和未经本机记录的活动转发保持不动。主机按设备加文件锁，并记录自己的转发供异常退出后恢复。
+
+手机正常画面实测为 640 × 1422，逻辑半尺寸为 630 × 1422，右侧含对齐填充。接收器兼容 16 像素边界的尾部填充，保留逻辑视口和 JPEG 存储尺寸；UI 直接裁去填充，不重新编码 JPEG，输入仍映射到 1260 × 2844。旋转或无法匹配的尺寸仍会关闭控制。
+
+完整自动化检查通过 93 项：54 项原生、33 项 UI/格式/坐标、6 项 USB 桥接与底座协议检查。浏览器另外确认模拟画面的尾部彩色填充被裁去，放大时可见区域保持居中；这些界面测试不等同于真机性能测试。

+
+实际商业手机拒绝普通 `kill <pid>`，返回 `Permission denied`；同一身份的 `kill -9 <pid>` 成功，进程随即消失。此前残留代理能响应 Driver RPC，却无法恢复采集，因此不将无条件复用残留代理作为恢复策略。官方 `xdevice-ohos 6.1.0.210` 的 `ohos/proxy/ui_proxy.py::stop_ui_rpc` 与 `proxy_base.py::_kill_uitest` 均使用 `kill -9`；默认销毁代理对象可不杀进程，显式重连则先停止。插件只借鉴结束自己代理的方式，绝不照搬按名称批量结束所有工具进程的逻辑。[官方连接包](https://pypi.org/project/xdevice-ohos/6.1.0.210/)
