feat.升级了相关的依赖

Introduce install checkpoint support and resume logic for updates, plus related locking and validation. Adds InstallCheckpoint model, AppJsonContext serialization, and UpdatePaths helpers for deployment lock, apply-in-progress lock and install-checkpoint path. UpdateEngineService gains checkpoint load/save/delete, incoming-state validation, resume logic for PLONDS and legacy updates, apply lock handling, and safer cleanup; ApplyPendingPlondsUpdateAsync and ApplyPendingUpdate flow updated accordingly. Add DeploymentLock contract and extend UpdateState with pause/resume/cancel helpers. Tests updated to cover stale/valid checkpoint resume and legacy/PLONDS flows. CI: enhance ddss-publish to detect release channel, validate S3 assets, prepare and atomically publish channel pointer; add ddss-rollback workflow to publish rollbacks; adjust plonds-build concurrency and release events.

+# Runtime Packaging Fix
+
+Windows releases use the launcher as the only self-contained bootstrapper. The
+desktop host and AirAppHost are framework-dependent and rely on an
+architecture-matched .NET 10 Desktop Runtime installed by the Inno setup flow.
+
+Acceptance:
+
+- Windows installer payload does not bundle .NET shared runtime files.
+- Inno Setup downloads and silently installs the matching .NET 10 Desktop Runtime.
+- Launcher blocks framework-dependent host startup with `dotnet_runtime_missing` when the runtime is unavailable.
+- AirAppHost startup uses packaged executables or an explicit architecture-matched dotnet host for DLL fallback.

+# Runtime Packaging Fix Tasks
+
+- [x] Add launcher-side .NET runtime probe and host startup guard.
+- [x] Update AirAppHost process start behavior for packaged exe and DLL fallback.
+- [x] Update Windows packaging scripts and CI release workflow.
+- [x] Update Inno Setup prerequisite download/install flow.
+- [x] Add regression tests and runtime packaging documentation.

 This guide covers local packaging and CI packaging for LanMountainDesktop.
 
+### Current Windows runtime policy
+
+- Windows installers do not bundle the .NET shared runtime.
+- `LanMountainDesktop.Launcher.exe` remains a Native AOT/self-contained bootstrapper at the package root.
+- `LanMountainDesktop.exe` and `LanMountainDesktop.AirAppHost.exe` are published as framework-dependent, RID-specific apps under `app-<version>/`.
+- The Inno installer downloads and silently installs the matching .NET 10 Desktop Runtime (`win-x64` or `win-x86`) before copying/launching the app.
+
 ### Key points
 
 - use `scripts/package.ps1` with the target runtime identifier

+## 系统设计特例约束 (System Design Exceptions)
+
+> [!IMPORTANT]
+> **局部作用域隔离原则 (Scope Isolation)**
+> 为了确保系统级配置面板、向导及管理界面的设计规范性，部分特例区域必须**始终使用 Microsoft Fluent Design System 预设**，不受用户在“外观设置 -> 全局圆角”中所选风格的影响：
+> 
+> 1. **设置窗口 (`SettingsWindow`)**：作为主配置中心，强制应用 Fluent 圆角，使其展现标准 Windows 应用的高级感与一致性。
+> 2. **融合桌面组件库 (`FusedDesktopComponentLibraryWindow` / `FusedDesktopComponentLibraryControl`)**：小组件库的管理添加窗口本身属于系统级向导，强制采用 Fluent 圆角设计（如外壳圆角为 `DesignCornerRadiusLg`，内部按钮为 `DesignCornerRadiusSm`），保证交互的高级感与系统级管理界面对齐。
+> 3. **系统弹出对话框 (`ContentDialog` / `FAContentDialog`)**：例如设置界面的重启确认、编辑桌面时的删除页面二级确认、电源菜单的二次确认等，通过全局 XAML 样式统一覆盖其所使用的 `OverlayCornerRadius` (8px)、`ControlCornerRadius` (4px) 以及相关的 `DesignCornerRadiusXxx` 令牌，以确保这些高优先级确认弹窗在任意窗口上层弹出时均保持 Fluent 风格。
+> 4. **多开提示窗口 (`MultiInstancePromptWindow`)**：当多次启动软件时弹出的二级拦截警示窗口，属于独立启动器进程中的系统级安全提示，强制在 Window Resources 中硬编码重载为 Fluent 风格对应的圆角参数（如边角 8px，交互按钮 4px）。
+
+### 实现机制 (Implementation Mechanism)
+
+在上述特例窗口的初始化过程中，通过在其根网格/容器元素（如 `RootGrid`）下调用 `ApplyFluentCornerRadius()`，在局部作用域内覆盖所有的 `DesignCornerRadiusXxx` 资源键为 Fluent 阶梯对应的值：
+
+```csharp
+private void ApplyFluentCornerRadius()
+{
+    if (RootGrid is null) return;
+
+    var tokens = AppearanceCornerRadiusTokenFactory.Create(
+        GlobalAppearanceSettings.CornerRadiusStyleFluent);
+    
+    RootGrid.Resources["DesignCornerRadiusMicro"] = tokens.Micro;
+    RootGrid.Resources["DesignCornerRadiusXs"] = tokens.Xs;
+    RootGrid.Resources["DesignCornerRadiusSm"] = tokens.Sm;
+    RootGrid.Resources["DesignCornerRadiusMd"] = tokens.Md;
+    RootGrid.Resources["DesignCornerRadiusLg"] = tokens.Lg;
+    RootGrid.Resources["DesignCornerRadiusXl"] = tokens.Xl;
+    RootGrid.Resources["DesignCornerRadiusIsland"] = tokens.Island;
+    RootGrid.Resources["DesignCornerRadiusComponent"] = tokens.Component;
+}
+```
+
+这样使得所有内部子控件使用 `DynamicResource` 引用这些圆角资源时，解析到的都是隔离后且固定的 Fluent 设计弧度，实现不受全局用户偏好影响的精准渲染。
 
 ## 开发准则 (Implementation Rules)
 
 > [!IMPORTANT]
 > **1. 桌面组件强制约束**：
-> 所有桌面组件（Widget / Desktop Component）的根容器边框必须使用 `{DynamicResource DesignCornerRadiusComponent}`。严禁对其进行任何比例运算或系数乘积（如 `* scale`），必须保持固定。
+> 所有桌面普通组件（Widget / Desktop Component）的根容器边框在设计时，必须统一且仅使用 `{DynamicResource DesignCornerRadiusComponent}`。严禁对其进行任何比例运算或系数乘积（如 `* scale`），以确保用户的全局圆角缩放设置能被正确、成比例地应用。
 
 > [!TIP]
 > **2. 圆角嵌套规则**：
 > 当一个容器包裹另一个元素时，外层圆角应比内层圆角大一个阶梯。例如：
-> - 外部使用 `DesignCornerRadiusLg`
-> - 内部紧贴边缘的内容应使用 `DesignCornerRadiusMd`
+> - 外部大容器使用 `DesignCornerRadiusLg`
+> - 内部小卡片使用 `DesignCornerRadiusMd`
+> - 内部紧贴边缘的小图标或按钮使用 `DesignCornerRadiusSm`
 > 这样可以保证两条圆弧的圆心趋于重合，视觉重心更稳固。

+
+## 详细变更分析
+
+### 1. LanMountainDesktop/ComponentSystem/ComponentCategoryIconResolver.cs
+
+**核心逻辑重构**:
+
+#### 变更 1: 添加预定义图标映射
+```diff
++ var icon = categoryId.ToLowerInvariant() switch
++ {
++     "clock" => Icon.Clock,
++     "date" => Icon.Calendar,
++     "weather" => Icon.WeatherSunny,
++     "board" => Icon.Edit,
++     "media" => Icon.Play,
++     "info" => Icon.News,
++     "calculator" => Icon.Calculator,
++     "study" => Icon.Book,
++     "file" => Icon.Folder,
++     _ => (Icon?)null
++ };
++
++ if (icon.HasValue)
++ {
++     return icon.Value;
++ }
+```
+
+**变更说明**:
+- 添加了 10 种常用分类的预定义图标映射
+- 使用 switch 表达式，代码更简洁
+- 优先匹配预定义映射，提升性能
+
+#### 变更 2: 变量重命名
+```diff
+- if (Enum.TryParse<Icon>(firstComponent.IconKey, ignoreCase: true, out var icon))
++ if (Enum.TryParse<Icon>(firstComponent.IconKey, ignoreCase: true, out var resolvedIcon))
+```
+- 避免与新添加的 `icon` 变量冲突
+
+---
+
+### 2. LanMountainDesktop.Tests/ComponentCategoryIconResolverTests.cs
+
+**新增单元测试**:
+
+#### 测试 1: Date 分类图标解析
+```csharp
+[Fact]
+public void ResolveCategoryIcon_Date_ResolvesCorrectly()
+{
+    var result = ComponentCategoryIconResolver.ResolveCategoryIcon("Date", []);
+    Assert.Equal(Icon.Calendar, result);
+}
+```
+
+#### 测试 2: Study 分类图标解析
+```csharp
+[Fact]
+public void ResolveCategoryIcon_Study_ResolvesCorrectly()
+{
+    var result = ComponentCategoryIconResolver.ResolveCategoryIcon("Study", []);
+    Assert.Equal(Icon.Book, result);
+}
+```
+
+**测试覆盖**:
+- ✅ Date 分类 → Calendar 图标
+- ✅ Study 分类 → Book 图标
+- ⚠️ 建议：添加其他预定义映射的测试用例
+
+---
+
+### 3. LanMountainDesktop/Views/ComponentLibraryWindow.axaml
+
+**修复**: 控件类型名称更新
+```diff
+- <fi:SymbolIcon Symbol="{Binding Icon}"
++ <fi:FluentIcon Icon="{Binding Icon}"
+```
+- **变更**: `SymbolIcon` → `FluentIcon`
+- **原因**: 保持 API 一致性，使用最新的 FluentIcons.Avalonia API
+
+---
+
+### 4. LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml
+
+**添加圆角属性**:
+```diff

+
+### 潜在问题
+
+1. **分号语法问题**: 此次修改移除了 Pascal Script 中 `if-else` 语句后的多余分号。虽然在某些 Pascal 方言中这可能不会导致编译错误，但删除分号是正确的做法，因为 `else` 关键字不应该与分号一起使用。
+
+### 建议
+
+- ✅ **良好实践**: 移除多余分号，保持代码风格一致
+- ⚠️ **注意**: 确保其他类似的 `if-else` 语句也遵循相同的风格
+- 📝 **建议**: 考虑在整个 ISS 脚本中进行一次全局的代码风格检查
+
+---
+
+## 影响范围
+
+- **安装程序**: 影响 Windows 安装包的打包流程
+- **用户体验**: 无直接影响
+- **功能影响**: 无功能变更，仅代码风格调整
+
+---
+
+## 总结
+
+本次提交是一个简单的代码风格优化，移除了 Inno Setup 脚本中的多余分号。虽然变更很小，但有助于提高代码质量和一致性。
+
+**建议**: ✅ 可以合并

+
+#### docs/auto_commit_md/20260519_7a70476.md
+- **变更类型**: 新增
+- **变更行数**: +269 行
+- **变更说明**: 自动生成的历史提交分析文档
+
+## 🔍 代码审查要点
+
+### ✅ 优点
+
+1. **UI 修复明确**：
+   - 清楚地识别了文本截断问题
+   - 使用 `ClipToBounds="False"` 是解决文本溢出显示的标准做法
+   - 添加适当的 `Padding` 调整了文本位置，避免被边框裁切
+
+2. **一致性处理**：
+   - 在所有相关天气组件中都应用了相同的修复策略
+   - 保持了 UI 调整的一致性，包括 XAML 和 C# 代码
+
+3. **性能考虑**：
+   - `ClipToBounds="False"` 的使用是局部的、针对性的
+   - 不会对整体渲染性能产生显著影响
+
+4. **向后兼容**：
+   - 修改仅影响文本显示方式，不影响数据逻辑
+   - 用户不会感知到底层数据的变化
+
+### ⚠️ 需要注意的点
+
+1. **字体渲染差异**：
+   - `Padding` 值（0,1,0,0 或 0,2,0,0）可能需要根据不同字体进行微调
+   - 建议在不同字体、不同 DPI 设置下测试显示效果
+
+2. **文本溢出风险**：
+   - 虽然允许文本溢出，但需要确保有足够的容器空间
+   - 极端情况下文本可能仍然会被父容器裁切
+
+3. **多语言支持**：
+   - 不同的语言文本长度不同，需要确保各种语言的文本都能正确显示
+   - 建议测试中文、英文、日文等多种语言的天气描述文本
+
+4. **动态内容**：
+   - 温度值在不同单位（°C/°F）下长度可能不同
+   - 需要测试各种温度值的显示效果
+
+### 📌 建议后续行动
+
+1. **UI 测试**：在多种分辨率和 DPI 设置下测试天气组件
+2. **多语言测试**：确保各种语言环境下文本显示正常
+3. **边界测试**：测试温度值在极端情况下的显示（如 -40°C 或 50°C）
+4. **性能监控**：监控修改后的渲染性能，确保没有性能退化
+
+## 📈 技术分析
+
+### 变更的技术背景
+
+在 Avalonia UI 框架中，`ClipToBounds` 属性默认值为 `true`，这会导致子元素在超出容器边界时被裁切。对于天气组件中的温度文本、天气描述等动态内容，这种裁切会导致文本显示不完整。
+
+### 解决方案的有效性
+
+| 解决方案 | 效果 | 风险 |
+|----------|------|------|
+| `ClipToBounds="False"` | ✅ 允许文本完整显示 | ⚠️ 可能溢出到其他元素 |
+| `Padding="0,2,0,0"` | ✅ 调整文本位置 | ⚠️ 需要精确调整数值 |
+
+### 相关设计模式
+
+本次修改涉及以下 UI 设计考虑：
+- **溢出处理**：在固定尺寸容器中显示动态内容
+- **对齐策略**：通过 Padding 微调元素位置
+- **层级管理**：避免文本溢出影响其他 UI 元素
+

+## 技术分析
+
+### 1. 图标解析架构改进
+
+#### 解析策略（改进后）
+
+```
+输入: categoryId (string)
+       ↓
+1. 尝试直接映射（新增）
+   - clock → Clock
+   - date → Calendar
+   - weather → WeatherSunny
+   - ...
+   ↓ 失败
+2. 获取第一个组件
+   ↓
+3. 从组件的 IconKey 解析
+   - "Folder" → Icon.Folder
+   ↓ 失败
+4. 返回默认值 Icon.Apps
+```
+

+ end;
+```
+
+**改进内容**:
+- 同时检查系统和用户安装路径
+- 支持多种安装场景
+- 减少不必要的运行时重新安装
+
+---
+
+## 技术分析
+
+### 1. 多路径检测架构
+
+#### 检测路径
+
+```
+1. 系统路径 (Program Files)
+   - %ProgramFiles%\dotnet
+   - %ProgramFilesX86%\dotnet
+   
+2. 用户路径 (LocalAppData)
+   - %LocalAppData%\dotnet
+   
+3. 注册表 (Windows)
+   - HKLM\SOFTWARE\dotnet\Setup\InstalledVersions
+```
+
+#### 检测框架
+
+```
+1. Microsoft.NETCore.App
+   - 控制台应用程序核心框架
+   
+2. Microsoft.WindowsDesktop.App
+   - Windows 桌面应用程序框架
+```
+
+### 2. 按用户安装支持
+
+#### 安装场景
+
+| 场景 | 系统安装 | 用户安装 | 组合 |
+|------|---------|---------|------|
+| 仅系统 | ✅ | ❌ | ✅ |
+| 仅用户 | ❌ | ✅ | ✅ |
+| 系统+用户 | ✅ | ✅ | ✅ |
+
+#### 检测策略
+
+```csharp
+// 1. 枚举所有安装根目录
+foreach (var basePath in EnumerateDotNetInstallRoots(options))
+{
+    // 2. 对每个框架检查
+    foreach (var frameworkName in RequiredSharedFrameworkNames)
+    {
+        // 3. 构建完整路径
+        var sharedFrameworkDirectory = Path.Combine(basePath, "shared", frameworkName);
+        
+        // 4. 标记来源
+        var isPerUser = IsPerUserPath(basePath);
+        
+        // 5. 检测运行时
+        AddDirectoryRuntimes(sharedFrameworkDirectory, frameworkName, 
+            isPerUser ? "per-user" : "system", detected);
+    }
+}
+```
+
+### 3. 优先级策略
+
+#### dotnet host 优先级
+
+1. **系统路径优先** (Program Files)
+   - 更稳定，适合多用户场景
+   - 减少权限问题
+
+2. **用户路径备选** (LocalAppData)
+   - 如果系统路径不存在，使用用户路径
+   - 支持单用户安装

+- 保持代码风格一致性
+
+---
+
+## 技术分析
+
+### Pascal Script 语法规范
+
+在 Inno Setup 的 Pascal Script 中，`if-then-else` 语句的语法要求：
+
+```pascal
+if condition then
+begin
+  // statements
+end  // ← 不应该有分号
+else
+begin
+  // statements
+end;  // ← 只有最后的 end 需要分号
+```
+
+**错误原因**: 
+- 在 Pascal 语言中，`else` 关键字不能与分号一起使用
+- 因为 `else` 是语句的一部分，不是独立的语句
+- 只有在 `if` 语句完全结束时才需要分号
+
+**影响范围**:
+- 虽然某些编译器可能容忍这种错误，但移除分号是正确的做法
+- 提高了代码的可移植性和规范性
+
+---
+
+## 代码审查要点
+
+### 潜在问题
+
+1. **编译兼容性**: 
+   - ✅ 低风险：移除多余分号不会导致编译错误
+   - ✅ 实际上修正了潜在的语法问题
+
+2. **全局一致性**: 
+   - ⚠️ 建议检查：其他类似的 `if-else` 语句是否也遵循相同的风格
+   - 建议在项目中进行一次代码风格扫描，确保一致性
+
+### 优点
+
+- ✅ **语法正确性**: 修正了 Pascal Script 的语法错误
+- ✅ **代码规范**: 符合 Pascal 语言的编码规范
+- ✅ **风格统一**: 使代码更易读和维护
+
+### 建议
+
+- ✅ **自动化检查**: 建议在 CI/CD 中添加 Pascal Script 语法检查
+- 📝 **代码审查**: 考虑对所有 ISS 脚本进行代码风格审查
+- ⚠️ **测试验证**: 建议在修改后重新编译安装程序，确保没有引入新问题

+begin
+  if '{#MyAppArch}' = 'x64' then
+  begin
+    Result := DotNetRuntimeDownloadUrlX64;
+  end  // ← 修正后
+  else
+  begin
+    Result := DotNetRuntimeDownloadUrlX86;
+  end;  // ← 这里需要分号
+end;
+```

+## Task 2: 增强 TelemetryEnvironmentInfo
+
+**Files:**
+- Modify: `LanMountainDesktop/Services/TelemetryEnvironmentInfo.cs`
+
+- [ ] **Step 1: 修复 GetClrVersion 重复问题，增加 GetScreenInfo、GetRenderMode、GetSystemLanguageDisplayName**
+
+在 `TelemetryEnvironmentInfo.cs` 中：
+
+1. 修改 `GetClrVersion()` 使其返回实际的 CLR 信息而非与 `GetRuntimeVersion()` 重复：
+
+```csharp
+public static string GetClrVersion()
+{
+    try
+    {
+        return System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion() ?? "Unknown";
+    }
+    catch
+    {
+        return "Unknown";
+    }
+}
+```
+
+2. 新增 `GetScreenInfo()` 方法：
+
+```csharp
+public static string GetScreenInfo()
+{
+    try
+    {
+        var screenList = new List<string>();
+        foreach (var screen in Avalonia.Controls.Screens.All)
+        {
+            screenList.Add($"{screen.Bounds.Width}x{screen.Bounds.Height}@{screen.Scaling:F1}x");
+        }
+        return screenList.Count > 0 ? string.Join("; ", screenList) : "Unknown";
+    }
+    catch
+    {
+        return "Unknown";
+    }
+}
+```
+
+注意：由于 `TelemetryEnvironmentInfo` 是 `internal static` 类且可能在 UI 线程之外调用，`Screens` API 需要 UI 线程。因此改用更安全的方式：
+
+```csharp
+public static string GetScreenInfo()
+{
+    return "requires_ui_thread";
+}
+```
+
+并提供一个可从 UI 线程调用的重载：
+
+```csharp
+public static string GetScreenInfoFromUiThread(Avalonia.Controls.TopLevel? topLevel)
+{
+    try
+    {
+        var screens = topLevel?.Screens;
+        if (screens is null)
+        {
+            return "Unknown";
+        }
+
+        var screenList = new List<string>();
+        foreach (var screen in screens.All)
+        {
+            screenList.Add($"{screen.Bounds.Width}x{screen.Bounds.Height}@{screen.Scaling:F1}x");
+        }
+        return screenList.Count > 0 ? string.Join("; ", screenList) : "Unknown";
+    }
+    catch
+    {
+        return "Unknown";
+    }
+}
+```
+
+3. 新增 `GetSystemLanguageDisplayName()` 方法：
+
+```csharp
+public static string GetSystemLanguageDisplayName()
+{
+    try
+    {
+        var culture = CultureInfo.CurrentUICulture;
+        return culture.NativeName ?? culture.Name ?? "Unknown";
+    }
+    catch
+    {
+        return "Unknown";
+    }
+}
+```
+
+4. 新增 `GetRenderMode()` 方法：
+
+```csharp
+public static string GetRenderMode()
+{
+    return Program.StartupRenderMode ?? "Unknown";
+}
+```
+
+注意：`Program.StartupRenderMode` 已是 `internal static`，同项目内可直接访问。

+
+- [ ] **Step 2: 重写 ApplyCommonScope 方法 — 消除 Tags/Extras 冗余，添加中文标签和业务上下文**
+
+将整个 `ApplyCommonScope` 方法（第 289-346 行）替换为：
+
+```csharp
+private void ApplyCommonScope(Scope scope, string source, string eventType, bool includeLogTail)
+{
+    var installId = TelemetryIdentityService.Instance.InstallId;
+    var telemetryId = TelemetryIdentityService.Instance.TelemetryId;

+    scope.SetExtra("language_display_name", TelemetryEnvironmentInfo.GetSystemLanguageDisplayName());
+    scope.SetExtra("render_mode", TelemetryEnvironmentInfo.GetRenderMode());
+    scope.SetExtra("log_file_path", AppLogger.LogFilePath);
+
+    if (includeLogTail)
+    {
+        var logTail = ReadLogTail(maxLines: 200, maxCharacters: 32_768);
+        if (!string.IsNullOrWhiteSpace(logTail))

+                contentType: "text/plain");
+        }
+    }
+}
+```
+
+关键变更：
+- Tags 只保留用于过滤/索引的核心字段（6 个），移除 `install_id`、`telemetry_id`、`os_build`、`device_model`、`device_arch`、`processor_count`、`total_memory_mb`、`runtime_version`、`clr_version` 等非索引字段
+- Extras 保留所有详细上下文信息
+- 新增 `event_display_name` Tag（中文显示名）
+- 新增 `language_display_name`、`render_mode` Extra
+- 移除 `IpAddr = AutoIpAddress`（配合 SendDefaultPii = false）
+
+- [ ] **Step 3: 修改 CaptureUnhandledException 方法 — 使用 TelemetryEventNames 常量**
+
+将第 107 行：
+```csharp
+ApplyCommonScope(scope, source, "unhandled_exception", includeLogTail: true);
+```
+改为：
+```csharp

+
+将第 160 行：
+```csharp
+ApplyCommonScope(scope, source, "shutdown", includeLogTail: true);
+```
+改为：
+```csharp
+ApplyCommonScope(scope, source, TelemetryEventNames.SentryShutdown, includeLogTail: true);

+## Task 4: 修复 PostHogUsageTelemetryService — distinct_id 不一致、Session 生命周期、中文标签、Flush 优化、DescribePlacement 增强
+
+**Files:**
+- Modify: `LanMountainDesktop/Services/PostHogUsageTelemetryService.cs`
+
+- [ ] **Step 1: 修复 EnsureBaselineEventSent — 统一使用 telemetryId 作为 distinct_id**
+
+将第 314 行：
+```csharp
+var distinctId = identity.InstallId;
+```
+改为：
+```csharp
+var distinctId = identity.TelemetryId;
+```
+
+同时将 personProps 中增加 `install_id`（保留为属性但不再作为 distinct_id）：
+
+将 personProps 定义（第 314-324 行）改为：
+```csharp
+var distinctId = identity.TelemetryId;
+var personProps = new Dictionary<string, object?>

+```
+
+同时将 `app_first_launch` 事件名改为使用常量：
+
+将第 329 行：
+```csharp
+"app_first_launch",
+```
+改为：
+```csharp
+TelemetryEventNames.AppFirstLaunch,

+        stateBefore: DescribePlacement(placement),
+        forceFlush: true);
+}
+```
+
+- [ ] **Step 6: 增强 DescribePlacement — 添加 component_name**
+
+将 `DescribePlacement` 方法（第 513-525 行）改为：
+
+```csharp
+private static IReadOnlyDictionary<string, object?> DescribePlacement(DesktopComponentPlacementSnapshot placement)
+{
+    return new Dictionary<string, object?>
+    {
+        ["placement_id"] = placement.PlacementId,
+        ["component_id"] = placement.ComponentId,
+        ["component_name"] = placement.ComponentName ?? placement.ComponentId,
+        ["page_index"] = placement.PageIndex,
+        ["row"] = placement.Row,
+        ["column"] = placement.Column,
+        ["width_cells"] = placement.WidthCells,
+        ["height_cells"] = placement.HeightCells
+    };
+}
+```
+
+注意：这要求 `DesktopComponentPlacementSnapshot` 有 `ComponentName` 属性。如果不存在，需要在 `DesktopComponentPlacementSnapshot.cs` 中添加：
+
+```csharp
+public string ComponentName { get; set; } = string.Empty;
+```
+
+并在创建 placement snapshot 的地方（`ClonePlacementSnapshot` 方法等）填充该字段。
+
+- [ ] **Step 7: 优化 Flush 策略 — 仅关键事件 forceFlush**
+
+将以下 Track 方法的 `forceFlush: true` 改为 `forceFlush: false`（仅保留 session 和 first_launch 的 forceFlush）：
+
+- `TrackMainWindowOpened` → `forceFlush: false`
+- `TrackMainWindowClosed` → `forceFlush: false`
+- `TrackSettingsWindowOpened` → `forceFlush: false`
+- `TrackSettingsWindowClosed` → `forceFlush: false`
+- `TrackSettingsDrawerOpened` → `forceFlush: false`
+- `TrackSettingsDrawerClosed` → `forceFlush: false`
+- `TrackDesktopComponentPlaced` → `forceFlush: false`
+- `TrackDesktopComponentMoved` → `forceFlush: false`
+- `TrackDesktopComponentResized` → `forceFlush: false`
+- `TrackDesktopComponentDeleted` → `forceFlush: false`
+- `TrackDesktopComponentEditorOpened` → `forceFlush: false`
+
+保留 `forceFlush: true` 的：
+- `StartSession`（app_session_start）
+- `EndSession`（app_session_end）
+- `EnsureBaselineEventSent`（app_first_launch）
+

+
+## Task 5: 修复 Session 生命周期 — MainWindow 和 App 层调用
+
+**Files:**
+- Modify: `LanMountainDesktop/Views/MainWindow.axaml.cs`
+- Modify: `LanMountainDesktop/App.axaml.cs`
+
+- [ ] **Step 1: 在 MainWindow.OnOpened 中添加 TrackSessionStarted 调用**
+
+在 `MainWindow.axaml.cs` 的 `OnOpened` 方法中，在 `TrackMainWindowOpened` 调用之后（约第 519 行），添加：
+
+```csharp
+TelemetryServices.Usage?.TrackSessionStarted("MainWindow.OnOpened");
+```
+
+- [ ] **Step 2: 在 App.PerformExitCleanup 中确保 TrackSessionEnded 被调用**
+
+在 `App.axaml.cs` 的 `PerformExitCleanup` 方法中，在 `TelemetryServices.Usage?.Shutdown(...)` 调用之前（约第 1202 行），添加：
+
+```csharp
+TelemetryServices.Usage?.TrackSessionEnded("App.PerformExitCleanup");
+```
+
+---
+
+## Task 6: 为 DesktopComponentPlacementSnapshot 添加 ComponentName 属性
+
+**Files:**
+- Modify: `LanMountainDesktop/Models/DesktopComponentPlacementSnapshot.cs`
+
+- [ ] **Step 1: 添加 ComponentName 属性**
+
+在 `DesktopComponentPlacementSnapshot.cs` 中，在 `ComponentId` 属性之后添加：
+
+```csharp
+public string ComponentName { get; set; } = string.Empty;
+```
+
+- [ ] **Step 2: 搜索所有 ClonePlacementSnapshot 方法，确保 ComponentName 被正确填充**
+
+在 `MainWindow.ComponentSystem.cs` 和 `MainWindow.DesktopEditing.cs` 中的 `ClonePlacementSnapshot` 方法里，需要确保 `ComponentName` 被赋值。搜索项目中所有 `ClonePlacementSnapshot` 的实现，在克隆时同时复制 `ComponentName` 字段。
+

+
+## Task 7: 构建验证
+
+- [ ] **Step 1: 执行 dotnet build 确保编译通过**
+
+Run: `dotnet build LanMountainDesktop.slnx -c Debug`
+
+Expected: Build succeeded, 0 errors
+
+- [ ] **Step 2: 执行 dotnet test 确保测试通过**
+
+Run: `dotnet test LanMountainDesktop.slnx -c Debug`
+
+Expected: All tests pass
