 截至 2026-08-14（Asia/Hong_Kong），首期实现已经冻结以下决策：
 
-1. Sidecar 调用 HIDMaestro v1.6.1 的公共 `HIDMaestro.Core.dll` API，不复制其实现，也不调用 HIDMaestroTest UI。
-2. HIDMaestro 使用官方发布物 `HIDMaestro-v1.6.1.zip`，固定下载地址和 SHA-256 `00145c23d9838be6089389ce58b3fd2b6766fa9bc0f1f3c60a3c885361b53c34`。发布物大小为 118,879,222 bytes。
+1. Sidecar 调用 HIDMaestro v1.6.2 的公共 `HIDMaestro.Core.dll` API，不复制其实现，也不调用 HIDMaestroTest UI。

 3. Sunshine 安装包仅携带自研 Sidecar 的 `win-x64` 自包含 .NET 运行时，不携带 HIDMaestro DLL。GUI 在用户明确选择安装时下载第三方发布物，校验后只提取 Core、许可证、README 和第三方通知。
 4. 首期每个 Sunshine 进程只允许一个虚拟 DualSense。Xbox 360、DualShock 4 和既有自动模式继续走 ViGEm，不改变成熟驱动支持范围。
 5. 客户端只选择 `physical` 或 `emulated`。前者预检 USB DualSense 四声道端点后声明 `ML_FF_DS5_HAPTICS_PCM`；后者声明 `ML_FF_DS5_HAPTICS_IR_V2`。两位互斥且不在运行中自动切换。
