Review comments at @tools/mat-capture/quantum_v4_recorder.cpp:
- Line 61: 调整 Recorder::begin 中对全局 registry_ 的 CAS 使用：改为按 encoder 或 binding
隔离的有界无等待同步，使不同 renderer 或空 domain 不会因无关争用触发 fail()；同时保留同一 encoder 并发 pass 的拒绝行为。
Review comments at @tools/sonic-mat-live/manage-live.ps1:
- Around line 64-65: 更新 manage-live.ps1 中创建 $deployment 的逻辑：目录不存在时才创建；目录已存在时，使用
SID 检查所有者是否为 Administrators 或 SYSTEM，并拒绝不受信任的所有者。随后禁用 ACL 继承，并将目录权限限制为仅
Administrators 和 SYSTEM 可写，避免沿用标准用户可控制的目录或权限。
Review comments at @tools/sonic-mat-live/spatial_probe.cpp:
- Line 229: 在参数校验中更新 `seconds` 的范围检查，使用 `std::isfinite` 拒绝 NaN
和无穷值，同时保留现有设备索引及秒数上下限校验。

96-96: 🎯 Functional Correctness该审查意见的前提不成立：
NativeMatPipeSource::descriptor()返回的默认Descriptor已满足 MAT 会话要求，不会导致音频立即失败。
EncodedAudioSource::Descriptor的默认值为版本 1、Format::mat_iec61937、Clock::carrier_48000和 48000 Hz。这些值与先前审查记录中mat_live_session.h的启动检查一致，即版本 1、MAT 格式、48 kHz 时钟和采样率。因此，返回{}得到的就是该源的 MAT 格式契约。该意见引用的
mat_live_session.h:51-53检查仅来自先前审查记录，本轮未直接读取该文件。即便如此，记录中的要求与默认值完全一致，因此无法构成拒绝默认描述符的依据。

Add an opt-in (mat_live, default off) Windows path that streams native live MAT (codec 7) from the local capture tool's fixed pipe. - RTSP: DESCRIBE leases the pipe and advertises the live profile when the client asks; ANNOUNCE accepts only the exact profile, rejects duplicate or mixed MAT attributes, and otherwise releases the lease so compatible clients fall back to Opus. A source failure after selection ends the session. - The pipe source verifies the elevated publisher deployed under Program Files by content hash, pipe server PID, process creation times and the native descriptor before reading; status queries never open the pipe. - Each IEC carrier cycle is fragmented, sealed with AES-128-GCM and a 64-bit counter, and paced per cycle from frame arrival so device clock drift cannot accumulate; authenticated END follows a clean source EOS. - The audio broadcast path skips CBC for MAT, reports send failures, and uses a loss-intolerant try_raise instead of clear-on-full. - /api/mat/status reports read-only lease/stream observations.

The Audio/Video tab gets one MAT toggle and a status line polled from /api/mat/status while visible. Retired pipe/producer keys are dropped on load and save. Strings are added to every locale.

Windows CTest targets cover the host sender against a mock client (reconnect, cancellation, source/clock/sequence failures, slow-source drift, watchdog), the shared AEAD vectors and bounded mock output. tests/mat-live also holds the on-demand RTSP/UDP, UI, ticket, watchdog and Android JNI mock harnesses; they are excluded from the aggregate GoogleTest suite. Co-authored-by: qiin <chou0212@163.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
The opt-in tool observes pre-mix plugin object passes in audiodg (dynamic objects and 7.1.4 static beds, at most 20 inputs, 48 kHz/480 frames), bridges them to a dedicated MAT worker and publishes complete carrier cycles on the fixed local pipe. - Verified audioeng.dll and Dolby Access builds are listed once in mat_compat.h. Preflight/Start print a COMPONENT line per dependency and stop with exit code 3 before any hook or elevation on an unverified build. - Dolby Access is located by package family; the worker re-checks the directory shape and pinned DLL hashes inside audiodg. - manage-live.ps1 deploys under Program Files with ACL/reparse checks, verifies each protected copy against build.json, runs the elevated preflight from that copy and passes manifest hashes to the publisher. - CI runs the own-process capture, bridge, IPC, pipe, compatibility and operator regressions; no native capture runs in CI.

Covers enabling the host, the trusted automatic source, session and failure semantics, supported object layouts, system component versions, CI versus on-demand verification and the archived history branches.

) ## 改了啥呀 把「先开脚本、再开 MAT」这只杂鱼收掉：Windows 安装版随附采集组件，用户只操作 **MAT 开关、保存并应用，以及必要的 Windows 授权**。客户端继续 mock。 - 安装包携带采集器、对象 tap、独立 MAT worker 和 MinHook 许可；仍不打包 Dolby 系统组件。MinGW 主机通过独立 MSVC 构建生成这些运行文件。默认开启，可用 `-DSUNSHINE_BUILD_MAT_CAPTURE=OFF` 跳过 MAT 工具查找、构建和打包，允许不安装 Visual Studio 的 MinGW 环境使用。 - Sunshine 启动时按已应用的开关启动采集器，关闭并应用、退出或主机意外终止时协作停止。重启等待旧采集器收尾，不强杀、不强制卸载 DLL，不增加常驻服务或自动重试。 - 安装服务已有权限时直接启动；独立运行时在后台请求必要的 UAC，避免阻塞 Web UI。SYSTEM 模式按当前会话用户的 SID 查询 Dolby Access。 - 安装路径逐级校验所有者、写权限和重解析点。DLL 按内容哈希命名，并由采集器内置哈希校验；升级等待采集器退出，签名流程保留哈希绑定 DLL 的原始字节。 - UI 继续只有开关和只读状态，增加启动失败原因，更新 20 份语言文案；不再要求用户运行管理脚本。开发诊断入口仍保留。 ## 为啥要改 已合入的 #1177 完成了实时采集与串流，但部署和启动仍依赖开发者脚本。这次只补安装和生命周期交接，复用已有采集、停止恢复、认证与协商实现。客户端、共享依赖指针、音频格式、端点和驱动行为均未修改。 自动入口只选择**唯一可确认的系统 audiodg**；没有或存在多个候选时显示失败，不尝试逐个注入。仍受现有组件哈希兼容表及受保护的 Program Files 安装路径约束。 ## 验证 本机补验（当前 `aa80c8e26`，2026-11-06）： - 从新的构建目录完整编译 Sunshine 主机、服务和安装工具，MAT 组件保持启用；前端重新构建，3 组 MAT CTest 全部通过。完整 Inno 安装器生成成功。 - 已备份现有程序及配置，使用完整安装器原位升级；按现有 CI 的发布命名运行 `sunshine-windows-installer.exe`，退出 0。安装后的主机和 MAT 运行文件与暂存产物逐项 SHA256 一致。 - 在实际安装服务中切换配置并调用同一个应用/重启 API，验证 disabled → 自动启动采集器 → 不支持组件时 error → disabled、无残留进程；最后按字节恢复原配置，并保留原有延迟自动启动。服务正常运行。 - 退出码 3 来自主机对真实子进程句柄的 GetExitCodeProcess 结果，另核对该进程已不存在；没有收到独立 WMI stop trace，不将它列为独立退出观测证据。 - **本机 audioeng.dll 已更新至 26100.9818，不在兼容表内。仅验收了自动启动和兼容性拒绝后的清理；未注入 audiodg，也未验收成功采集时的协作停止、实时音频或 HDMI 播放。客户端保持 mock，本轮未启动客户端。** - 本地构建关闭可选 RTX HDR / DLSS NR 适配器。默认 all 目标另在既有 nvprefs_unit_tests 遇到本机 MinGW 头文件未声明 FileRenameInfoEx；该独立测试缺少主机已有的 Windows 版本定义，本轮未修改无关代码。上述主机、工具、MAT 回归及安装器目标均成功，不能据此声称本机所有目标/测试通过。 - 当前 head 的 Windows、Setup Release、MAT software regressions、VDD helper smoke tests 和 CodeRabbit 均成功（Actions run 42192443015）；不等同于人工批准。 构建选项修复 `aa80c8e26`： - 新增默认 ON 的 SUNSHINE_BUILD_MAT_CAPTURE；OFF 在查找 PowerShell/创建目标前返回，Inno 的 MAT 文件清单也随目标是否存在启停。仅改 4 个文件（+11/−1）。 - 隔离 CMake 构建图验证 OFF 不查询 MAT 工具，默认目标和依赖接法与主机构建一致的 sunshine 占位目标均无 MAT 命令；ON 保留依赖，实际调用现有 package.ps1/MSVC 构建运行组件通过。此项不是 Sunshine 全量重建。 - 两种配置生成的 Inno 清单分别使用 #if 0 / #if 1；git diff --check 通过。当前 head CI/review 结果见上方。 - Docstring Coverage 是 CodeRabbit 的统计警告（已有报告为 10.71%，阈值 80%），没有列出具体缺失函数；本轮未批量补注释或改审查策略，不宣称该警告已解决。 已验证的 review 修复 `ab4a49bf5`： - 移除安装脚本重复拼接的 DESTDIR；已有安装测试增加普通 prefix 与 DESTDIR 两种暂存。修复前稳定复现 DLL 落入重复路径，修复后均通过。 - 停止事件仅向普通已验证用户授予 SYNCHRONIZE；已有管道测试确认观察者无修改权限，创建者仍可发出停止通知，子进程能等待并退出。 - 同步组件不受支持时的状态文档。 - MSVC 的 mat_pipe、mat_package 以及 MinGW 管道/生命周期回归通过；git diff --check 通过。仅修改 5 个相关文件，客户端和依赖未动。 - ab4a49b 的 MAT/VDD/Setup Release 已通过，Windows 构建未在本轮推送前完成；不代替 aa80c8e 的新 CI。既有两条行内线程已修复并关闭。 初版 `0d47bd7` 的本机软件验证（不冒充本轮全量重跑）： - MSVC 运行组件构建及 8 项 CTest 全部通过：既有对象/回调/兼容表、动态与 7.1.4 FAKE IPC、管道生命周期，以及新增安装包文件/内置哈希校验。 - 现有管道测试补充开关停止、真实普通子进程退出通知、PID 创建时间不符、未安装失败和 ACL 契约；另以 MinGW 编译、运行通过。 - 当前用户与显式 SID 的只读 Dolby 包查询结果一致。 - 现有 PowerShell 管理入口/manifest/ACL 回归通过。 - 4 项 MAT Web UI 测试、Web UI 构建、全量 Web UI lint、翻译键校验及 git diff --check 通过。 - 独立 CMake 集成构建验证 MinGW 调用 MSVC 生成运行组件。新工作区未完成 Sunshine 本机全量重建，完整主机及安装器构建交由本 PR Windows CI。 - 隔离 UI 预检已调整为断言缺少安装组件时明确失败，本轮仅语法检查，未重新运行完整主机会话。 - 全量 i18n 格式检查仍遇到 master 中已有的 en.json 非 MAT 键排序问题；本次未改动这些键。 以上初版验证当时未进行实际安装；本次已补实际安装与开关错误路径，范围及原生采集边界见当前 head 的本机补验。未运行卸载或真实 HDMI/Atmos 播放。
改了啥呀
Windows 主机增加实验性的 MAT 实时采集与认证串流（
mat_live，默认关闭），客户端输出继续 mock。用户只需在音频/视频页打开开关并查看只读状态；采集工具与主机经固定本地入口自动交接，无需复制程序路径或管道参数。生产链路只有一条：plugin 混音前对象捕获 → 对象桥 → 独立原生 MAT worker → 本机有界管道 → Sunshine 实时会话。普通音频路径不加载原生 worker，Opus/AC3/PCM 行为不变。

采集工具
audioeng.dll与 Dolby Access DLL 只在mat_compat.h列出的已验证哈希上运行。Preflight/Start 先为每个组件输出COMPONENT行（版本、哈希、是否支持），未验证时以退出码 3 结束，不挂钩也不提权；manage-live.ps1给出提示，Status 显示Unsupported。build.json校验，提权 preflight 从已校验副本运行，传给发布器的是 manifest 哈希，而不是用户可写构建目录里的文件。范围外：旧半块组装器、有限回放、codec4/5、落盘输入和旧对象来源 kind 1 已删除或拒绝。Android 只保留 JNI、完整 RTSP/视频会话和 mock 验收；网络排障工具、历史 Android 应用及其依赖不在本 PR。
为啥要改
把实时链路需要的实现留下，把历史实验和闲置分支收掉。用户只需开关和状态；开发者仍能定位身份、采集、数据完整性、组件版本及收尾问题，不增加配置项或管理层。

当前 head
bf0129b，基于 master441b2b8，121 个文件、+10,282/−14 行（其中约 2,900 行是按.clang-format展开的单行语句）。moonlight-common-c随 master 为733025a，已包含 MAT 共享协议提交24f2369（common-c #40）。CI（run 40508854248）
ffdd546上通过（run 40484828577）；之后进入主程序的只有mat_live_session.h的发送节奏，以及native_mat_guard.h改为引用新增的常量表mat_compat.h；其余改动在 worker/工具侧，已由 MAT 回归编译。本轮 review 修复的本机验证
Live MAT missed deadline，修复后mat_live_host_tests全部通过。此前结果（各自对应当时版本，提交见备份分支）
053c21f21：Sunshine 重建、隔离配对/启动/退出预检通过；主机发送/mock 输出、采集选项、对象桥、并发回调、动态与 7.1.4 IPC（各 1,300 轮 FAKE worker）、管道生命周期回归通过。c7067eb20的独立软件实验跑通真实 RTSP/视频/JNI 链路（两次各 500 周期、全部 303 个 H.264 单元、SHA/EOS 一致）。均不代表原生 MAT 编码或 Dolby 解码验收。未验收：真实 HDMI/eARC/Atmos 播放、接收端逐声道解码、长期实采、真实采集重连、游戏音画同步，以及本轮修改后的原生 Preflight/Start。本轮未执行原生采集、设备播放或端点/驱动/服务修改。
