🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win在 owner-disconnect 清理前保留策略失败状态。
DeviceRegistry.Attach在发送AttachReply后才启动DefaultAudioEndpointGuard。如果第二次 attach 后 Windows 选择虚拟端点作为默认设备，主机可以在AttachReply之后发送AudioPolicyViolation。自测随后直接关闭客户端，只等待serverTask完成。它不会读取或检查该事件，因此可能输出成功结果。Suggested fix

#176的全部内容。公开仓库确认提交
0c5d2667fde2c10601a237783e3afb819cfd0597存在，且标题涉及 1.4.3。现有证据仍不能确认该提交包含 PR#176、#174 和#175的全部变更，也不能确认父仓库可以获取并构建该提交。
为默认音频恢复修复发布组件 1.4.3，让已安装 1.4.2 的用户能够通过现有升级机制收到修复，版本号可别把修复藏住啦。 ### 改了啥呀 - `component-compatibility.json`：组件版本从 1.4.2 升为 1.4.3。 - 调整现有升级测试，确认 1.4.2 属于需要更新的旧版本。 只涉及这两个文件，基于主仓库锁定的 GUI 提交 d5b22c2。配套主仓库修复：AlkaidLab/foundation-sunshine#1172 。 ### 验证 - `cargo test --manifest-path src-tauri/Cargo.toml dualsense:: --no-default-features -- --test-threads=1`：48 通过、3 个环境测试默认忽略。 - 指定本次 1.4.3 runtime 后，`staged_sidecar_implements_the_shared_transport_contract --ignored --exact`：通过。 - Sidecar 发布、自检和探测通过。本轮主机有活动串流，未运行创建设备的验收。
固定的 `%TEMP%\sunshine-ds5-profiles` 可能遗留不可写权限或被并发进程覆盖，导致补丁配置加载失败，最后只表现为功能不可用。让这个杂鱼临时目录各用各的，并把失败原因交代清楚。 ### 改了啥呀 - 使用 `Directory.CreateTempSubdirectory` 创建本次加载专用目录，在 SDK 同步加载结束后的 `finally` 清理；旧固定目录保持原样。 - 配置加载失败直接抛出包含实际路径、原始错误消息和内部异常的错误，避免回退后误报能力缺失。清理失败仅记录完整警告，不覆盖加载错误或使成功加载失败。 - 范围仅 `DeviceRegistry.cs`：16 行新增、12 行删除。基于已合入 #1172 的 master，音频恢复、USB/IP、GUI 和 SDK 均无新增修改。 ### 验证 - Sidecar Release 自包含 `dotnet publish`、`--self-check`、`--probe`：通过。 - 对实际编译产物做隔离 ACL 回归：旧版在固定目录禁止写入时复现能力丢失，新版保留触觉和原神能力且不改旧目录；成功加载后目录已清理；6 个并发进程通过；临时根目录不可写时保留 `UnauthorizedAccessException` 和实际路径。 - 从当前源码提取加载方法，以真实目录 I/O 和文件占用测试 3 个生命周期场景：加载失败仍清理、清理失败只警告、两者同时失败仍保留加载原因。SDK 加载边界使用替身；验证文件保存在本地 build 目录。 - GUI `staged_sidecar_implements_the_shared_transport_contract --ignored --exact` 指向本次完整运行时：通过。
本机真实 USB/IP 验收中，Windows 将新建 DualSense 音频端点选为默认设备，触发音频保护并结束会话；自检又忽略了保护事件，最后只报 EOF。修复这条已复现路径，让这个杂鱼 EOF 把原因交代清楚。
