 - 切回中文后 SenseVoice 正常。
 - 下载失败和中断下载不破坏 Moonshine/SenseVoice。
 
+## 5. QA 预检补丁
+
+QA 预检中已补充两处修复：
+
+- 下载过程中不再把 Engine UI 误显示为 Loading；旧 Moonshine/SenseVoice 引擎保持当前状态显示。
+- App 退出或重启导致的旧 `.downloads/<model>` partial，会在下一次同模型下载前清理，避免长期占用磁盘。
+
+补丁后再次通过：
+
+```bash
+cd privatevoice.src
+go test ./... -count=1
+```
+
+日志：`logs/go-test-all-20260603-round4-after-qa-fix.log`
+
+补丁后再次通过：
+
+```bash
+cd privatevoice.src/frontend
+npm run build
+```
+
+日志：`logs/npm-run-build-20260603-round4-after-qa-fix.log`
