-# 版本同步说明
+# 版本号自动同步说明
 
-## 目标
+## 📋 概述
 
-发布版的用户可见版本必须统一指向“应用版本”，不能再出现：
+从本次更新开始，Release 工作流已配置为**自动同步版本号**，确保应用的每个版本号来源都保持一致。
 
-- Launcher UI 显示 `1.0.0`
-- 应用设置页显示 `0.8.x`
-- `version.json`、安装包、Release 资产名称各写各的
+## 🔄 版本号流转链路
 
-## 默认仓库状态
+```
+Git Tag (v1.0.1)
+    ↓
+[Release 工作流 prepare 任务]
+    ↓
+提取版本号: 1.0.1
+    ↓
+[Update version in .csproj] ✨ 新增步骤
+    ↓
+自动更新 .csproj 文件版本号
+    ↓
+dotnet restore/build
+    ↓
+构建时读取更新后的版本号
+    ↓
+应用内显示版本号 (MainWindow.Localization.cs 动态读取)
+```
 
-仓库内的静态版本现在故意保留为开发占位值：
+## 🎯 工作原理
 
-- `Directory.Build.props`
-- `LanMountainDesktop/LanMountainDesktop.csproj`
-- `LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj`
-- `LanMountainDesktop.Shared.Contracts/LanMountainDesktop.Shared.Contracts.csproj`
-- `LanMountainDesktop/app.manifest`
-- `LanMountainDesktop.Launcher/app.manifest`
+### 1. 版本号提取
+当推送 Git Tag 时（如 `git tag v1.0.1`），Release 工作流的 `prepare` 任务自动提取版本号：
+- TAG: `v1.0.1` → VERSION: `1.0.1`
 
-这些值只是提醒“当前不是正式注入构建”，不能代表发布版本。
+### 2. 自动更新 .csproj
+在三个平台的构建任务中，新增了 **"Update version in .csproj"** 步骤：
 
-## Release 工作流怎么做
+**Windows (PowerShell)**:
+```powershell
+$VERSION = "1.0.1"
+(Get-Content file.csproj) -replace '<Version>.*?</Version>', "<Version>$VERSION</Version>" | Set-Content file.csproj
+```
 
-Release 工作流会先从 tag 提取版本：
+**Linux/macOS (Bash)**:
+```bash
+VERSION="1.0.1"
+sed -i "s/<Version>.*<\/Version>/<Version>$VERSION<\/Version>/" file.csproj
+```
 
-- `v0.8.5.2` -> `0.8.5.2`
-- 程序集四段版本 -> `0.8.5.2`
+### 3. 构建和发布
+更新后的版本号被用于：
+- 程序集版本 (`AssemblyVersion`)
+- 包文件名 (`LanMountainDesktop-1.0.1-win-x64.zip`)
+- 应用内显示 (About 页面)
+- GitHub Release 标题
 
-随后显式执行：
+## 📍 涉及的文件
 
-- `scripts/Set-ReleaseVersion.ps1`
+自动更新的文件：
+1. `LanMountainDesktop/LanMountainDesktop.csproj`
 
-这个步骤会同步更新：
+## ✅ 使用流程
 
-- 主程序 `.csproj` 的 `Version`
-- Launcher `.csproj` 的 `Version`
-- Shared.Contracts `.csproj` 的 `Version`
-- `Directory.Build.props`
-- 主程序 `app.manifest`
-- Launcher `app.manifest`
+### 发布新版本
 
-之后构建和发布阶段继续通过 MSBuild 属性注入：
+```bash
+# 1. 更新代码（可选：代码中的版本号现在会自动更新）
+git add .
+git commit -m "feat: Add new features"
 
-- `Version`
-- `AssemblyVersion`
-- `FileVersion`
-- `InformationalVersion`
+# 2. 创建版本标签
+git tag v1.0.1
+# 或带注释的标签
+git tag -a v1.0.1 -m "Release v1.0.1"
 
-因此最终会统一落到：
+# 3. 推送标签到 GitHub
+git push origin v1.0.1
 
-- Launcher UI 读取到的应用版本
-- 应用设置页显示的版本
-- `version.json`
-- 程序集文件版本
-- Windows manifest
-- 安装包版本
-- GitHub Release 资产名称
+# 4. Release 工作流自动运行：
+#    - 自动更新 .csproj 文件
+#    - 构建所有平台
+#    - 创建 GitHub Release
+#    - 附带所有平台的发布包
+```
 
-## 维护规则
+## 🔒 版本号一致性保证
 
-- 日常开发不要手动把仓库默认版本改成正式版本号。
-- 正式发版只需要打 tag，版本同步交给工作流。
-- 如果新增新的版本承载点，必须同时补到 `Set-ReleaseVersion.ps1` 和 Release 工作流里。
+现在应用的三个版本号来源完全同步：
+
+| 来源 | 说明 | 自动更新 |
+|------|------|--------|
+| `.csproj` <Version> | 项目文件版本 | ✅ 是 |
+| 程序集版本 | 编译时读取 | ✅ 是 |
+| 应用内显示 | About 页面 | ✅ 是 |
+| 发布包文件名 | Release 工作流 | ✅ 是 |
+| GitHub Release | Release 工作流 | ✅ 是 |
+
+## ⚠️ 注意事项
+
+### 不需要手动更新
+- ❌ 不需要在 `.csproj` 中手动修改 Version
+- ❌ 不需要修改多个地方的版本号
+
+### 只需执行
+- ✅ 创建 Git Tag: `git tag v1.0.1`
+- ✅ 推送 Tag: `git push origin v1.0.1`
+- ✅ 其他由工作流自动处理
+
+## 📊 版本号格式
+
+支持的格式：
+- ✅ `v1.0.0` (builds -> 1.0.0)
+- ✅ `v1.2.3` (builds -> 1.2.3)
+- ✅ `v2.0.0-rc1` (builds -> 2.0.0-rc1, 如果需要)

-            - `LanMountainDesktop_${{ needs.prepare.outputs.version }}_amd64.deb`
+            ### Windows
+            - **LanMountainDesktop-Setup-${{ needs.prepare.outputs.version }}-x64.exe** - 64-bit installer (includes .NET runtime)
+            - **LanMountainDesktop-Setup-${{ needs.prepare.outputs.version }}-x86.exe** - 32-bit installer (includes .NET runtime)
 
-            ### Payload Archives
-            - `files-windows-x64.zip`
-            - `files-windows-x86.zip`
-            - `files-linux-x64.zip`
+            Installation: Double-click the .exe file and follow the wizard.
+
+            ### Incremental Update (Windows x64)
+            - **files.json** - Update manifest listing changed files
+            - **files.json.sig** - RSA signature of the manifest
+            - **update.zip** - Archive containing changed files
+
+            Existing users: The app will automatically detect and apply the incremental update on next launch.
+
+            ### Linux
+            - **LanMountainDesktop-${{ needs.prepare.outputs.version }}-linux-x64.deb** - Debian package (x64)
 
             ### macOS
-            - macOS assets are best-effort and will not block the release.
+            - **LanMountainDesktop-${{ needs.prepare.outputs.version }}-macos-x64.dmg** - Intel processor
+            - **LanMountainDesktop-${{ needs.prepare.outputs.version }}-macos-arm64.dmg** - Apple Silicon (M1/M2/M3)
 
-            Release keeps only the stable installer and payload outputs. PLONDS delta assets and external mirror metadata are generated by follow-up workflows.

-# LanMountainDesktop Launcher 全面改进计划
-
-## 概述
-
-本计划旨在将 LanMountainDesktop 的 Launcher 改进为符合原子化架构的独立启动器，参考 ClassIsland 的极简设计，同时保留阑山桌面的特色功能。
-
-## 目标
-
-1. **P0 (必须完成)**: 重写 Launcher 为极简模式，移除与主程序的耦合
-2. **P1 (应该完成)**: 将 OOBE、Splash、更新、插件管理迁移到主程序
-3. **P2 (推荐完成)**: 实现 Launcher 自更新机制
-4. **P3 (可选优化)**: 性能优化和代码清理
-5. **P4 (长期规划)**: 增强功能和可扩展性
-
-## 当前问题
-
-1. Launcher 是 Avalonia 应用，启动慢、内存占用高
-2. Launcher 引用了 PluginSdk，与主程序有耦合
-3. 主程序引用了 Launcher，构建关系复杂
-4. Launcher 职责过多（OOBE + Splash + 更新 + 插件 + 启动）
-5. 缺少 Launcher 自更新机制
-6. GitHub Actions 工作流需要适配新的目录结构
-
-## 改进后架构
-
-```
-安装根目录/
-├── LanMountainDesktop.exe              ← 启动器（唯一入口，极简，~100行代码）
-├── app-1.0.0/                          ← 版本目录
-│   ├── .current                        ← 当前版本标记

-└── .launcher/                          ← 启动器数据（可选）
-    └── snapshots/                      ← 版本快照
-```
-
-## 详细实施步骤
-
-### P0: 基础架构重构
-
-#### 1. 重写 Launcher 为极简模式
-
-**文件**: `LanMountainDesktop.Launcher/Program.cs`
-
-**目标**: 
-- 代码量控制在 100 行以内
-- 零外部依赖（不使用 Avalonia）
-- 只负责：版本选择、启动主程序、清理旧版本
-
-**完整实现代码**:
-
-```csharp
-// LanMountainDesktop.Launcher/Program.cs
-using System.Diagnostics;
-using System.Runtime.InteropServices;
-
-namespace LanMountainDesktop.Launcher;

-
-#### 2. 修改 Launcher 项目文件
-
-**文件**: `LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj`
-
-**完整内容**:
-
-```xml
-<Project Sdk="Microsoft.NET.Sdk">
-  <PropertyGroup>
-    <OutputType>WinExe</OutputType>
-    <TargetFramework>net10.0</TargetFramework>
-    <Nullable>enable</Nullable>
-    <ImplicitUsings>enable</ImplicitUsings>
-    <Version>1.0.0</Version>
-    <ApplicationIcon>Assets\logo_nightly.ico</ApplicationIcon>
-  </PropertyGroup>
-  
-  <!-- 图标资源 -->
-  <ItemGroup>
-    <Content Include="..\LanMountainDesktop\Assets\logo_nightly.ico" Link="Assets\logo_nightly.ico">
-      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
-    </Content>
-  </ItemGroup>
-</Project>
-```
-
-#### 3. 移除主程序对 Launcher 的引用
-
-**文件**: `LanMountainDesktop/LanMountainDesktop.csproj`
-
-**修改**: 删除以下行
-```xml
-<!-- 删除这一行 -->
-<ProjectReference Include="..\LanMountainDesktop.Launcher\LanMountainDesktop.Launcher.csproj" ReferenceOutputAssembly="false" />
-```
-
-#### 4. 修改主程序支持新架构
-
-**文件**: `LanMountainDesktop/Program.cs`
-
-**修改**: 添加环境变量读取
-
-```csharp
-// 在 Program.cs 中添加
-internal static class LaunchContext
-{
-    public static string? PackageRoot => 
-        Environment.GetEnvironmentVariable("LMD_PACKAGE_ROOT");
-    public static string? Version => 
-        Environment.GetEnvironmentVariable("LMD_VERSION");
-    public static bool IsLaunchedByLauncher =>

----
-
-### P2: 自更新机制
-
-#### 9. 实现 Launcher 自更新
-
-**修改文件**: `LanMountainDesktop.Launcher/Program.cs`
-
-```csharp

-
-### P3: 清理旧代码
-
-#### 11. 删除文件清单
-
-**删除以下文件/目录**:

-
-### P4: GitHub Actions 工作流修改
-
-#### 12. 修改 release.yml
-
-**关键修改点**:
-
-1. **Launcher 单独编译**:
-```yaml
-- name: Publish Launcher
-  run: |
-    dotnet publish LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj `
-      -c Release `
-      -o ./publish/launcher-win-x64 `
-      --self-contained `
-      -r win-x64 `
-      -p:PublishSingleFile=false `
-      -p:PublishTrimmed=false `
-      -p:DebugType=none
-```
-
-2. **目录结构调整**:
-```yaml
-- name: Restructure for Launcher
-  run: |
-    $version = "${{ needs.prepare.outputs.version }}"
-    $publishDir = "publish/windows-x64"
-    $launcherDir = "publish/launcher-win-x64"
-    $appDir = "app-$version"
-    
-    # 创建新结构
-    $newStructure = "publish-launcher/windows-x64"
-    New-Item -ItemType Directory -Path $newStructure -Force
-    
-    # 移动主程序到 app-{version}/
-    $appPath = Join-Path $newStructure $appDir
-    Move-Item -Path $publishDir -Destination $appPath -Force
-    
-    # 复制 Launcher 到根目录
-    Copy-Item -Path "$launcherDir\*" -Destination $newStructure -Recurse -Force
-    
-    # 创建 .current 标记
-    New-Item -ItemType File -Path (Join-Path $appPath ".current") -Force
-```
-
-3. **Linux/macOS 同样调整**:
-- Linux: 修改 DEB 打包流程
-- macOS: 修改 DMG 打包流程
-
-#### 13. 修改 build.yml
-
-**修改**: 移除 Launcher 相关构建步骤，因为 Launcher 现在完全独立
-
----
-
-### P5: 图标资源处理
-
-#### 14. Launcher 图标配置
-
-**方案**: 使用链接方式引用主程序图标
-
-**文件**: `LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj`
-
-```xml
-<ItemGroup>
-  <!-- 链接主程序的图标 -->
-  <Content Include="..\LanMountainDesktop\Assets\logo_nightly.ico" Link="Assets\logo_nightly.ico">
-    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
-  </Content>
-</ItemGroup>
-```
-
-#### 15. 安装程序配置
-
-**文件**: `LanMountainDesktop/installer/LanMountainDesktop.iss` (Inno Setup)
-
-**关键配置**:
-
-```ini
-[Setup]
-AppName=阑山桌面
-AppVersion={#MyAppVersion}
-DefaultDirName={autopf}\LanMountainDesktop
-OutputBaseFilename=LanMountainDesktop-Setup-{#MyAppVersion}-x64

-UninstallDisplayIcon={app}\LanMountainDesktop.exe
-
-[Files]
-; Launcher

-    public const string EnvironmentVariablePrefix = "LMD_";
-}

-
-## 详细实施步骤
-
-### P0: 架构调整（核心）
-
-#### 1. 调整 Launcher 项目引用
-
-**文件**: `LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj`
-
-**修改**:
-- 保留 Avalonia 依赖
-- 移除 PluginSdk 引用（Launcher 不需要）
-- 添加 Shared.Contracts 引用（用于 IPC）
-
-```xml
-<Project Sdk="Microsoft.NET.Sdk">
-  <PropertyGroup>
-    <OutputType>WinExe</OutputType>
-    <TargetFramework>net10.0</TargetFramework>
-    <Nullable>enable</Nullable>
-    <ImplicitUsings>enable</ImplicitUsings>
-    <ApplicationIcon>Assetsogo_nightly.ico</ApplicationIcon>
-  </PropertyGroup>
-
-  <ItemGroup>
-    <!-- 保留 Avalonia -->
-    <PackageReference Include="Avalonia" Version="11.3.12" />
-    <PackageReference Include="Avalonia.Desktop" Version="11.3.12" />
-    <PackageReference Include="Avalonia.Themes.Fluent" Version="11.3.12" />
-    
-    <!-- 只引用 Shared.Contracts（IPC 协议） -->
-    <ProjectReference Include="..\LanMountainDesktop.Shared.Contracts\LanMountainDesktop.Shared.Contracts.csproj" />
-  </ItemGroup>
-  
-  <!-- 图标资源 -->
-  <ItemGroup>
-    <Content Include="..\LanMountainDesktop\Assets\logo_nightly.ico" Link="Assets\logo_nightly.ico">
-      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
-    </Content>
-  </ItemGroup>
-</Project>
-```
-
-#### 2. 移除主程序对 Launcher 的引用
-
-**文件**: `LanMountainDesktop/LanMountainDesktop.csproj`
-
-**修改**: 删除 Launcher 引用
-```xml
-<!-- 删除 -->
-<!-- <ProjectReference Include="..\LanMountainDesktop.Launcher\LanMountainDesktop.Launcher.csproj" ReferenceOutputAssembly="false" /> -->
-```
-
-#### 3. 创建 IPC 通讯契约
-
-**新建文件**: `LanMountainDesktop.Shared.Contracts/Launcher/LauncherIpc.cs`
-
-```csharp
-namespace LanMountainDesktop.Shared.Contracts.Launcher;
-
-public enum StartupStage
-{
-    Initializing,
-    LoadingSettings,
-    LoadingPlugins,
-    InitializingUI,
-    Ready
-}
-
-public record StartupProgressMessage
-{
-    public StartupStage Stage { get; init; }
-    public int ProgressPercent { get; init; }
-    public string? Message { get; init; }
-    public DateTimeOffset Timestamp { get; init; } = DateTimeOffset.UtcNow;
-}
-
-public static class LauncherIpcConstants
-{
-    public const string PipeName = "LanMountainDesktop_Launcher";
-    public const string LauncherPidEnvVar = "LMD_LAUNCHER_PID";
-    public const string PackageRootEnvVar = "LMD_PACKAGE_ROOT";
-    public const string VersionEnvVar = "LMD_VERSION";
-}
-```
-
-### P1: Launcher 端实现
-
-#### 4. 实现 IPC 服务端
-
-**新建文件**: `LanMountainDesktop.Launcher/Services/Ipc/LauncherIpcServer.cs`
-
-```csharp
-using System.IO.Pipes;
-using System.Text.Json;
-using LanMountainDesktop.Shared.Contracts.Launcher;
-
-namespace LanMountainDesktop.Launcher.Services.Ipc;
-
-public class LauncherIpcServer : IDisposable
-{
-    private readonly CancellationTokenSource _cts = new();
-    private NamedPipeServerStream? _pipeServer;
-    private readonly Action<StartupProgressMessage> _onProgress;
-    
-    public LauncherIpcServer(Action<StartupProgressMessage> onProgress)
-    {
-        _onProgress = onProgress;
-    }
-    
-    public async Task StartAsync()
-    {
-        while (!_cts.Token.IsCancellationRequested)
-        {
-            try
-            {
-                _pipeServer = new NamedPipeServerStream(
-                    LauncherIpcConstants.PipeName,
-                    PipeDirection.In,
-                    1,
-                    PipeTransmissionMode.Message);
-                
-                await _pipeServer.WaitForConnectionAsync(_cts.Token);
-                
-                using var reader = new StreamReader(_pipeServer);
-                var json = await reader.ReadToEndAsync(_cts.Token);
-                
-                if (!string.IsNullOrEmpty(json))
-                {
-                    var message = JsonSerializer.Deserialize<StartupProgressMessage>(json);
-                    if (message != null)
-                    {
-                        _onProgress(message);
-                    }
-                }
-                
-                _pipeServer.Disconnect();
-            }
-            catch (OperationCanceledException)
-            {
-                break;
-            }
-            catch (Exception ex)
-            {
-                Console.Error.WriteLine($"IPC error: {ex.Message}");
-            }
-        }
-    }
-    
-    public void Dispose()
-    {
-        _cts.Cancel();
-        _pipeServer?.Dispose();
-        _cts.Dispose();
-    }
-}
-```
-
-#### 5. 修改 Launcher 启动流程
-
-**修改文件**: `LanMountainDesktop.Launcher/Services/LauncherFlowCoordinator.cs`
-
-```csharp
-public async Task<LauncherResult> RunAsync()
-{
-    // 1. 清理旧版本
-    _deploymentLocator.CleanupDestroyedDeployments();
-    
-    // 2. 检查并安装待处理的更新（主程序下载的）
-    var pendingUpdate = _updateEngine.CheckPendingUpdate();
-    if (pendingUpdate.HasUpdate)
-    {
-        _splashWindow?.UpdateStatus("正在安装更新...");
-        var updateResult = await _updateEngine.ApplyPendingUpdateAsync();
-        if (!updateResult.Success)
-        {
-            return updateResult;
-        }
-    }
-    
-    // 3. 检查并安装待处理的插件更新
-    var pendingPlugins = _pluginUpgradeQueueService.CheckPendingUpgrades();
-    if (pendingPlugins.HasUpgrades)
-    {
-        _splashWindow?.UpdateStatus("正在更新插件...");
-        var pluginResult = _pluginUpgradeQueueService.ApplyPendingUpgrades();
-        if (!pluginResult.Success)
-        {
-            return pluginResult;
-        }
-    }
-    
-    // 4. OOBE
-    if (_oobeStateService.IsFirstRun())
-    {
-        _splashWindow?.Hide();
-        foreach (var step in _oobeSteps)
-        {
-            await step.RunAsync(CancellationToken.None);
-        }
-        _splashWindow?.Show();
-    }
-    
-    // 5. 启动 IPC 服务端监听主程序进度
-    using var ipcServer = new LauncherIpcServer(msg =>
-    {
-        _splashWindow?.UpdateProgress(msg.ProgressPercent, msg.Message);
-    });
-    _ = ipcServer.StartAsync();
-    
-    // 6. 启动主程序
-    _splashWindow?.UpdateStatus("正在启动...");
-    var hostResult = LaunchHostWithIpc();
-    if (!hostResult.Success)
-    {
-        return hostResult;
-    }
-    
-    // 7. 等待主程序报告就绪或超时
-    await WaitForHostReadyOrTimeoutAsync(TimeSpan.FromSeconds(30));
-    
-    return new LauncherResult { Success = true };
-}
-```
-
-### P2: 主程序端实现
-
-#### 6. 实现 IPC 客户端
-
-**新建文件**: `LanMountainDesktop/Services/Launcher/LauncherIpcClient.cs`
-
-```csharp
-using System.IO.Pipes;
-using System.Text.Json;
-using LanMountainDesktop.Shared.Contracts.Launcher;
-
-namespace LanMountainDesktop.Services.Launcher;
-
-public class LauncherIpcClient : IDisposable
-{
-    private NamedPipeClientStream? _pipeClient;
-    
-    public async Task ConnectAsync(CancellationToken cancellationToken = default)
-    {
-        _pipeClient = new NamedPipeClientStream(
-            ".",
-            LauncherIpcConstants.PipeName,
-            PipeDirection.Out);
-        
-        await _pipeClient.ConnectAsync(5000, cancellationToken);
-    }
-    
-    public async Task ReportProgressAsync(StartupProgressMessage message)
-    {
-        if (_pipeClient?.IsConnected != true)
-            return;
-        
-        var json = JsonSerializer.Serialize(message);
-        using var writer = new StreamWriter(_pipeClient, leaveOpen: true);
-        await writer.WriteAsync(json);
-        await writer.FlushAsync();
-    }
-    
-    public void Dispose()
-    {
-        _pipeClient?.Dispose();
-    }
-}
-```
-
-#### 7. 主程序启动时报告进度
-
-**修改文件**: `LanMountainDesktop/App.axaml.cs`
-
-```csharp
-public override async void OnFrameworkInitializationCompleted()
-{
-    // 检查是否从 Launcher 启动
-    var launcherPid = Environment.GetEnvironmentVariable(LauncherIpcConstants.LauncherPidEnvVar);
-    if (!string.IsNullOrEmpty(launcherPid))
-    {
-        // 连接到 Launcher 的 IPC 服务端
-        _launcherIpc = new LauncherIpcClient();
-        await _launcherIpc.ConnectAsync();
-        
-        // 报告启动进度
-        await _launcherIpc.ReportProgressAsync(new StartupProgressMessage
-        {
-            Stage = StartupStage.Initializing,
-            ProgressPercent = 10,
-            Message = "正在初始化..."
-        });
-    }
-    
-    // 初始化设置
-    await _launcherIpc?.ReportProgressAsync(new StartupProgressMessage
-    {
-        Stage = StartupStage.LoadingSettings,
-        ProgressPercent = 30,
-        Message = "正在加载设置..."
-    });
-    InitializeSettings();
-    
-    // 加载插件
-    await _launcherIpc?.ReportProgressAsync(new StartupProgressMessage
-    {
-        Stage = StartupStage.LoadingPlugins,
-        ProgressPercent = 50,
-        Message = "正在加载插件..."
-    });
-    await InitializePluginsAsync();
-    
-    // 初始化 UI
-    await _launcherIpc?.ReportProgressAsync(new StartupProgressMessage
-    {
-        Stage = StartupStage.InitializingUI,
-        ProgressPercent = 80,
-        Message = "正在初始化界面..."
-    });
-    InitializeUI();
-    
-    // 就绪
-    await _launcherIpc?.ReportProgressAsync(new StartupProgressMessage
-    {
-        Stage = StartupStage.Ready,
-        ProgressPercent = 100,
-        Message = "就绪"
-    });
-    
-    base.OnFrameworkInitializationCompleted();
-}
-```
-
-### P3: 更新流程整合
-
-#### 8. 主程序下载更新
-
-**主程序职责**:
-```csharp
-// 主程序中的更新服务
-public class AppUpdateService
-{
-    public async Task DownloadUpdateAsync(string version, string downloadUrl)
-    {
-        // 使用多线程下载器下载更新包
-        var downloader = new MultiThreadedDownloader();
-        var targetPath = Path.Combine(
-            Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData),
-            "LanMountainDesktop",
-            ".launcher",
-            "update",
-            "incoming",
-            $"update-{version}.zip");
-        
-        await downloader.DownloadAsync(downloadUrl, targetPath);
-        
-        // 标记为待安装
-        File.WriteAllText(
-            Path.Combine(Path.GetDirectoryName(targetPath)!, ".pending"),
-            version);
-    }
-}
-```
-
-#### 9. Launcher 安装更新
-
-**Launcher 职责**:
-```csharp
-// Launcher 中的更新安装服务
-public class UpdateInstallationService
-{
-    public async Task<InstallResult> InstallPendingUpdateAsync()
-    {
-        var pendingPath = Path.Combine(
-            _appRoot,
-            ".launcher",
-            "update",
-            "incoming",
-            ".pending");
-        
-        if (!File.Exists(pendingPath))
-            return InstallResult.NoUpdate;
-        
-        var version = File.ReadAllText(pendingPath);
-        var updatePackagePath = Path.Combine(
-            Path.GetDirectoryName(pendingPath)!,
-            $"update-{version}.zip");
-        
-        // 创建新版本目录
-        var newVersionDir = Path.Combine(_appRoot, $"app-{version}");
-        Directory.CreateDirectory(newVersionDir);
-        File.WriteAllText(Path.Combine(newVersionDir, ".partial"), "");
-        
-        // 解压更新包
-        ZipFile.ExtractToDirectory(updatePackagePath, newVersionDir);
-        
-        // 验证文件完整性
-        // ...
-        
-        // 切换版本标记
-        var currentDir = _deploymentLocator.FindCurrentDeploymentDirectory();
-        if (currentDir != null)
-        {
-            File.Delete(Path.Combine(currentDir, ".current"));
-            File.WriteAllText(Path.Combine(currentDir, ".destroy"), "");
-        }
-        
-        File.WriteAllText(Path.Combine(newVersionDir, ".current"), "");
-        File.Delete(Path.Combine(newVersionDir, ".partial"));
-        
-        // 清理待安装标记
-        File.Delete(pendingPath);
-        File.Delete(updatePackagePath);
-        
-        return InstallResult.Success;
-    }
-}
-```
-
-### P4: GitHub Actions 工作流
-
-#### 10. 修改 release.yml
-
-**关键修改点**:
-
-```yaml
-# 1. Launcher 单独编译（保留 Avalonia）
-- name: Publish Launcher
-  run: |
-    dotnet publish LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj `

-      --self-contained `
-      -r win-x64 `
-      -p:PublishSingleFile=false `
-      -p:DebugType=none
-
-# 2. 目录结构调整
-- name: Restructure for Launcher
-  run: |
-    $version = "${{ needs.prepare.outputs.version }}"
-    $publishDir = "publish/windows-x64"
-    $launcherDir = "publish/launcher-win-x64"
-    $appDir = "app-$version"
-    
-    # 创建新结构

-- [x] Host can expose strong-typed public IPC services.
-- [x] External .NET client can connect and call built-in services.
-- [x] Host publishes launcher startup and loading-state notifications through routed notify.
-- [x] Launcher consumes routed notify instead of the old primary custom named-pipe path.
-- [x] Plugin SDK exposes public IPC contribution primitives.
-- [x] Plugin runtime can discover and register plugin public IPC services.
-- [x] Public catalog includes built-in and plugin-contributed services.

-# External IPC Public API Spec
-
-## Goal
-
-Provide a single `dotnetCampus.Ipc` based external integration layer for:
-
-- Host public APIs
-- Launcher/OOBE startup progress and loading-state notifications
-- plugin-contributed public services and live event push
-
-## Delivered
-
-- `LanMountainDesktop.Shared.IPC` project
-- `[IpcPublic]` based built-in public contracts
-- `PublicIpcHostService` and `LanMountainDesktopIpcClient`
-- Launcher migrated to Host public IPC notifications
-- Plugin SDK public IPC contribution API
-- Host runtime integration for plugin public IPC services
-
-## Out of Scope
-
-- plugin process isolation
-- non-.NET strong-typed public IPC clients
-- live plugin public service removal without restart

-# 独立设置窗口 Spec
-
-## Why
-
-- 当前设置窗口仍然带有桌面壳的 owner / anchor 语义，点击“回到 Windows”或触发桌面动画时，容易被一起隐藏或重新定位。
-- 产品新增了“在任务栏显示图标”和“启用滑入滑出动画”设置，需要明确边界：它们只影响桌面主窗口，不影响设置窗口。
-- 桌面底栏、托盘菜单、IPC、组件库等入口应当始终打开同一个独立设置窗口，而不是切换成附属浮窗或开关行为。
-
-## What Changes

-## ADDED Requirements
-
-### Requirement: 设置窗口为独立顶层窗口
-
-系统 SHALL 将设置窗口作为独立顶层窗口显示，而不是作为桌面主窗口的附属子窗。
-
-#### Scenario: 设置窗口拥有独立任务栏图标
-- **WHEN** 用户打开设置窗口
-- **THEN** 设置窗口使用独立顶层窗口方式显示
-- **AND THEN** 设置窗口在任务栏中保留自己的独立按钮和图标
-- **AND THEN** “在任务栏显示图标”开关不会影响设置窗口的任务栏按钮
-
-### Requirement: 设置入口统一为 open-or-focus
-
-系统 SHALL 让所有设置入口打开或聚焦同一个设置窗口实例。
-
-#### Scenario: 已打开时重复触发设置入口
-- **WHEN** 设置窗口已经打开，用户再次从桌面、托盘或 IPC 触发打开设置
-- **THEN** 系统只聚焦现有设置窗口
-- **AND THEN** 如果请求包含目标页，则导航到目标页
-- **AND THEN** 不会把已打开的设置窗口当作开关关闭
-
-### Requirement: 设置窗口不参与桌面壳可见性切换
-
-系统 SHALL 让桌面壳的隐藏、最小化和进出场动画只作用于主窗口。
-

-# Launcher OOBE and Elevation Hardening Spec
-
-## Goal
-
-Stabilize the launcher startup path so that:
-
-- OOBE does not reappear for the same Windows user after reinstall/upgrade.
-- Normal startup, OOBE, update checks, incremental downloads, and default plugin installs do not trigger unexpected UAC prompts.
-- Only the approved elevation paths remain allowed.
-
-## Scope
-
-- Launcher OOBE state handling
-- launch source classification
-- elevation boundary cleanup
-- plugin install default behavior
-- diagnostic logging and troubleshooting guidance
-
-## Behavior
-
-- OOBE state is stored as a per-user truth source at `%LOCALAPPDATA%\LanMountainDesktop\.launcher\state\oobe-state.json`.
-- `first_run_completed` is treated as a legacy compatibility marker only.
-- `launchSource` values are treated as:
-  - `normal`
-  - `postinstall`
-  - `apply-update`
-  - `plugin-install`
-  - `debug-preview`
-- Automatic OOBE is allowed only for normal user-mode startup.
-- `postinstall` may show OOBE only when the launcher is not elevated and user state is available.
-- `apply-update`, `plugin-install`, and `debug-preview` must not auto-enter OOBE.
-- Allowed elevation paths are limited to:
-  - the installer itself
-  - full installer update application
-  - user-confirmed legacy uninstall
-- Default plugin installation targets the current user's LocalAppData scope and must not request elevation by default.
-
-## Acceptance
-
-- Same-user reinstall does not re-enter OOBE.
-- Missing or damaged OOBE state does not silently bounce the user back into OOBE loops.
-- Default plugin installation path never triggers surprise UAC.
-- Logs can explain why OOBE was shown or suppressed and why elevation was or was not requested.

-# Launcher 外壳托管、托盘兜底与高分屏动画修复
-
-## 背景
-
-当前桌面应用在以下场景存在明显不稳定性：
-
-- 设置页或升级后的“重启”没有统一回到 Launcher。
-- 已有实例处于托盘时，再次启动容易误报“窗口未显示”，甚至重复拉起。
-- 托盘初始化失败或运行中丢失时，应用可能进入无恢复入口状态。
-- Launcher 和宿主的版本来源不一致，发布后容易出现 UI 版本错乱。
-- 高分屏和混合缩放环境下，Launcher OOBE、主窗口入场和通知动画存在像素/DIP 混用问题。
-
-## 目标
-
-- Launcher 成为正式环境唯一的启动与重启入口。
-- 进入 `TrayOnly` 前必须先确认托盘可恢复。
-- Launcher UI 显示的版本号等于应用版本号。
-- 发布工作流显式同步主程序、Launcher、manifest 和产物版本。
-- 动画和定位统一按 DIP 与缩放计算。
-
-## 行为要求
-
-### 1. 重启接管
-
-- 应用内重启、插件升级后的重启都必须优先回到 Launcher。
-- Launcher 对 `SecondaryActivationSucceeded` 只认定为一次成功重定向，不允许再做 fallback 二次拉起。
-- Launcher 启动成功判定区分三类场景：
-  - 前台启动：`DesktopVisible` 或 `ActivationRedirected`
-  - 重启到最小化：`BackgroundReady`
-  - 重启到托盘：`TrayReady + BackgroundReady`
-
-### 2. 托盘硬约束
-
-- 托盘状态机必须至少覆盖：
-  - `Unavailable`
-  - `Initializing`
-  - `Ready`
-  - `Recovering`
-  - `Failed`
-- `HideMainWindowToTray`、关闭到托盘、重启恢复到托盘前都必须先执行托盘就绪检查。
-- 如果托盘不可用：
-  - 优先回退到任务栏最小化
-  - 若任务栏入口也不可用，则强制恢复前台可见
-- 托盘处于隐藏态期间必须运行 watchdog；连续恢复失败时自动恢复主窗口。
-
-### 3. 版本来源
-
-- Launcher 只能显示应用版本，不能显示 Launcher 自身硬编码版本。
-- 版本解析优先顺序：
-  - `version.json`
-  - 主程序文件版本 / 信息版本
-  - `app-<version>` 部署目录
-- Release 工作流必须显式打版本补丁，避免仓库默认占位值被误当成正式版本。
-
-### 4. 高分屏动画
-
-- 主窗口、通知、Launcher OOBE 的动画位移必须使用 DIP 或基于缩放换算后的尺寸。
-- 不允许直接把 `PixelRect` 宽高当作 `TranslateTransform` 或 `DesiredSize` 的输入。
-- 淡入和位移动画应并行执行，避免先淡入后滑动造成观感异常。
-
-## 验收
-
-- 已在托盘中的实例再次通过 Launcher 启动时，只激活已有实例。
-- 设置页重启和插件升级重启后，不再出现“窗口未显示但后台已有多个进程”。
-- 托盘失败时应用仍保持可恢复。
-- Launcher 与应用设置页显示相同版本。
-- 100% / 150% / 200% / 250% 缩放下，Launcher OOBE、主窗口入场、通知位置与动画正常。

-# PDC Incremental Update Migration
-
-## Goal
-
-Replace VeloPack-based incremental packaging with a unified PDC FileMap + object-repo pipeline, while keeping Launcher installation, rollback, and update orchestration ownership unchanged.
-
-## Stage 1 (Completed)
-
-- Release workflow removed VeloPack-based release packaging.
-- Signed FileMap path was restored as an interim release mechanism.
-- Host/Launcher fallback behavior stayed compatible with `files.json + files.json.sig + update.zip`.
-
-## Stage 2 (Current Implementation Target)
-
-- Move release publishing to PDCC + `phainon.yml` (ClassIsland-style).
-- Promote PDC-distributed FileMap/object-repo as the primary incremental path.
-- Keep GitHub Release installers and metadata as parallel distribution.
-- Keep Launcher state machine ownership (`.current/.partial/.destroy` + snapshots).
-- Update source defaults to `stcn` (S3/PDC), with GitHub fallback.
-- S3 object root is fixed to `lanmountain/update/` with no update-system version prefix.
-
-Expected S3 layout:
-  - `lanmountain/update/repo/<hash-prefix>/<hash-object>`
-  - `lanmountain/update/meta/channels/<channel>/<subchannel>/latest.json`
-  - `lanmountain/update/meta/distributions/<distributionId>/*.json`
-  - `lanmountain/update/installers/<platform>/<arch>/*`
-
-## Acceptance
-
-- `release.yml` includes PDCC publish steps and no Velopack steps.
-- Release jobs keep building installers for Windows x64/x86, Linux x64, and macOS.
-- PDC metadata + FileMap + object repo are published under `lanmountain/update/`.
-- Host can consume PDC payload (`stcn` source) and fallback to GitHub when unavailable.
-- Launcher can apply both:
-  - legacy signed `files.json + update.zip`
-  - PDC FileMap object-repo payload.
-- Rollback semantics remain unchanged.
-
-## Deprecated Notes
-
-- The following interim outputs are compatibility-only (not the long-term primary path):
-  - `files-windows-x64.json` / `.sig` / `update-windows-x64.zip`
-  - `files-windows-x86.json` / `.sig` / `update-windows-x86.zip`

-# Plugin Process Isolation
-
-## Why
-
-现有插件体系仍是“同进程 + AssemblyLoadContext 隔离”，无法阻止插件 fatal crash 拖垮 Host，也无法阻止插件直接访问 Host 进程内对象和内存。
-
-## What Changes
-
-- 增加插件运行模式概念：`in-proc`、`isolated-background`、`isolated-window`
-- 一期落地 `isolated-background`
-- 新建独立 IPC 契约包和 IPC 封装包
-- 在 `PluginSdk` 中新增 Worker 入口与 `runtime.mode`
-- 明确隔离模式下不再兼容对象实例共享型 API
-- 新增正式架构文档说明 UI 方案、迁移策略、残余风险和 ClassIsland 借鉴
-
-## Impact
-
-- `LanMountainDesktop.PluginSdk/`
-- `LanMountainDesktop.PluginTemplate/`
-- 新增 `LanMountainDesktop.PluginIsolation.Contracts/`
-- 新增 `LanMountainDesktop.PluginIsolation.Ipc/`
-- `docs/ARCHITECTURE.md`
-- `docs/PLUGIN_PROCESS_ISOLATION_ARCHITECTURE.md`
-
-## Requirements
-
-### Requirement 1
-
-宿主必须同时支持存量 `in-proc` 插件与未来的隔离插件，不得以本次改造打断旧插件加载。
-
-### Requirement 2
-
-隔离插件的 Host/Worker 通信必须基于显式 IPC 路由和 DTO，而不是 Host 服务对象实例共享。
-
-### Requirement 3
-
-一期必须把后台逻辑隔离为独立 Worker 进程，并显式记录 Host UI 壳层的残余风险。
-
-### Requirement 4
-
-仓库文档必须把 ClassIsland IPC 的借鉴点和不照搬的部分写清楚，避免后续实现阶段误把插件协议做成远程对象模型。
