-# 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

+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-Setup-${{ needs.prepare.outputs.version }}-x86.exe`
-            - `LanMountainDesktop_${{ 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`
+            **Note:** The Launcher is now built with AOT (Ahead-of-Time) compilation as a single executable file for faster startup and smaller footprint.
+
+            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.
+            See commits for changes.

-# LanMountainDesktop 启动器无法启动应用 - 问题分析与修复计划
-
-## 1. 项目架构概述
-
-LanMountainDesktop 采用**双进程架构**：
-- **Launcher** (`LanMountainDesktop.Launcher`) - 启动器，负责版本管理、更新、启动主程序
-- **Host** (`LanMountainDesktop`) - 主应用宿主
-
-### 启动流程
-1. 用户启动 `LanMountainDesktop.Launcher.exe`
-2. Launcher 扫描 `app-*` 目录，选择最佳版本
-3. 检查并应用待处理的更新
-4. 处理插件升级队列
-5. 启动主程序 `app-{version}/LanMountainDesktop.exe`
-6. 通过 IPC 监控主程序启动进度
-
-## 2. 问题分析
-
-### 2.1 核心问题：主机可执行文件找不到
-
-根据代码分析（`DeploymentLocator.cs`），启动器通过以下顺序查找主机可执行文件：
-
-1. **显式 app-root**（如果通过命令行指定）
-2. **已发布部署**（查找 `app-*` 目录）
-3. **可移植主机**（直接在应用根目录）
-4. **调试主机**（开发模式，查找构建输出路径）
-5. **旧版回退路径**
-
-**当前状态检查**：
-- ❌ 未找到 `app-*` 目录（生产部署结构不存在）
-- ❌ 未找到 `bin/Debug/**/*.exe`（项目未构建或构建输出不存在）
-
-### 2.2 可能的启动失败原因
-
-| 问题 | 描述 | 优先级 |
-|------|------|--------|
-| **项目未构建** | LanMountainDesktop 主程序未编译，没有可执行文件 | P0 |
-| **部署结构缺失** | 生产模式下缺少 `app-*` 目录结构 | P0 |
-| **开发模式路径问题** | 调试模式下路径计算错误或构建输出不在预期位置 | P1 |
-| **.NET 版本问题** | 项目使用 .NET 10.0，运行环境可能缺少对应运行时 | P1 |
-| **更新应用失败** | `ApplyPendingUpdateAsync` 失败导致无法完成部署 | P2 |
-| **IPC 连接超时** | 主程序启动后未及时建立 IPC 连接，导致启动器超时 | P2 |
-
-### 2.3 关键代码位置
-
-- **主机查找逻辑**: `LanMountainDesktop.Launcher/Services/DeploymentLocator.cs`
-  - `FindCurrentDeploymentDirectory()` - 查找 app-* 目录
-  - `ResolveHostExecutable()` - 解析主机路径
-  
-- **启动协调逻辑**: `LanMountainDesktop.Launcher/Services/LauncherFlowCoordinator.cs`
-  - `RunAsync()` - 主启动流程
-  - `LaunchHostWithIpcAsync()` - 启动主机进程
-  
-- **更新引擎**: `LanMountainDesktop.Launcher/Services/UpdateEngineService.cs`
-  - `ApplyPendingUpdateAsync()` - 应用待处理的更新
-
-## 3. 诊断步骤
-
-### 步骤 1：检查构建状态
-```bash
-dotnet --info
-dotnet build LanMountainDesktop.slnx -c Debug
-```
-
-### 步骤 2：验证主机可执行文件是否存在
-检查以下路径是否存在 `LanMountainDesktop.exe`：
-- `LanMountainDesktop/bin/Debug/net10.0/`
-- `LanMountainDesktop/bin/Release/net10.0/`
-
-### 步骤 3：测试直接运行主程序（跳过 Launcher）
-```bash
-dotnet run --project LanMountainDesktop/LanMountainDesktop.csproj
-```
-
-### 步骤 4：检查 Launcher 启动日志
-在开发模式下运行 Launcher 并查看控制台输出：
-```bash
-dotnet run --project LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj -- launch
-```
-
-## 4. 修复计划
-
-### 方案 A：构建并配置开发环境（推荐）
-
-**适用场景**：开发或调试环境
-
-1. **构建整个解决方案**
-   ```bash
-   dotnet restore
-   dotnet build LanMountainDesktop.slnx -c Debug
-   ```
-
-2. **验证构建输出**
-   - 确认 `LanMountainDesktop/bin/Debug/net10.0/LanMountainDesktop.exe` 存在
-   - 确认 `LanMountainDesktop.Launcher/bin/Debug/net10.0/LanMountainDesktop.Launcher.exe` 存在
-
-3. **测试 Launcher 启动**
-   ```bash
-   dotnet run --project LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj -- launch
-   ```
-
-4. **如果路径查找失败，检查 `DeploymentLocator.cs` 中的开发路径**
-   - 当前逻辑（第 366-375 行）查找：
-     - `../LanMountainDesktop/bin/Debug/net10.0/LanMountainDesktop.exe`
-     - `../LanMountainDesktop/bin/Release/net10.0/LanMountainDesktop.exe`
-   - 确认这些路径与实际的构建输出路径匹配
-
-### 方案 B：创建生产部署结构
-
-**适用场景**：生产环境或模拟生产环境
-
-1. **发布主程序**
-   ```bash
-   dotnet publish LanMountainDesktop/LanMountainDesktop.csproj -c Release -o app-1.0.0
-   ```
-
-2. **创建 .current 标记文件**
-   ```bash
-   echo. > app-1.0.0/.current
-   ```
-
-3. **从 Launcher 启动**
-   - Launcher 应该能找到 `app-1.0.0/LanMountainDesktop.exe`
-
-### 方案 C：修复潜在的代码问题
-
-如果上述方案无法解决问题，可能需要修复代码：
-
-#### C1. 增强错误处理和日志
-在 `DeploymentLocator.cs` 中添加更详细的日志输出，帮助诊断路径查找失败的原因。
-
-#### C2. 检查更新逻辑
-如果 `ApplyPendingUpdateAsync` 失败，可能导致启动中止。检查 `.launcher/update/incoming/` 目录是否有残留的更新文件。
-
-#### C3. 调整超时设置
-如果主程序启动较慢，可以适当增加 `LauncherFlowCoordinator.cs` 中的超时时间：
-- `StartupSoftTimeout` (当前 10 秒)
-- `StartupHardTimeout` (当前 30 秒)
-
-## 5. 建议执行顺序
-
-1. ✅ **首先执行方案 A 的步骤 1-2**（构建项目）
-2. ✅ **执行诊断步骤 3**（测试直接运行主程序）
-3. ✅ **执行诊断步骤 4**（查看 Launcher 启动日志）
-4. 根据日志输出决定后续操作：
-   - 如果显示 "host executable was not found" → 检查路径配置
-   - 如果显示 "update apply failed" → 清理更新缓存
-   - 如果主程序启动后超时 → 检查 IPC 连接或增加超时
-
-## 6. 验证方法
-
-修复后，通过以下方式验证：
-
-```bash
-# 开发模式启动
-dotnet run --project LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj -- launch
-
-# 或直接运行 Launcher 可执行文件
-# (需要先构建 Launcher)
-```
-
-启动后应该看到：
-1. Splash 窗口显示
-2. 主程序桌面窗口出现
-3. Launcher 自动退出（或最小化到托盘）
-
-## 7. 注意事项
-
-- 项目使用 .NET 10.0（`global.json` 指定版本 10.0.103）
-- 确保开发环境已安装对应的 .NET SDK
-- 如果修改了 `DeploymentLocator.cs` 的路径查找逻辑，需要同步更新文档 `docs/DEVELOPMENT.md`

-# Avalonia 12 Full Stack Migration
-
-## Summary
-
-LanMountainDesktop has moved its desktop stack to the Avalonia 12 baseline. The migration covers the main host, Launcher, Plugin SDK, plugin runtime loading policy, official WebView usage, ClassIsland Markdown, FluentAvalonia, FluentIcons, and Material-related dependencies.
-
-## Requirements
-
-### Requirement: Centralized Avalonia 12 dependency baseline
-
-The solution SHALL use central package management for direct Avalonia-facing projects and keep the core UI dependency baseline on Avalonia `12.0.1`.
-
-Required package baseline:
-
-- `Avalonia*` `12.0.1`
-- `Avalonia.Controls.WebView` `12.0.0`
-- `ClassIsland.Markdown.Avalonia` `12.0.0`
-- `FluentAvaloniaUI` `3.0.0-preview1`
-- `FluentIcons.Avalonia` `2.1.325`
-- `Material.Avalonia` `3.16.0`
-- `Material.Icons.Avalonia` `3.0.2`
-
-### Requirement: Official WebView
-
-The host SHALL use `Avalonia.Controls.NativeWebView` for the browser widget and SHALL NOT reference `WebView.Avalonia`, `AvaloniaWebView`, or `.UseDesktopWebView()`.
-
-Windows WebView2 user data configuration SHALL be supplied through `EnvironmentRequested` using `WindowsWebView2EnvironmentRequestedEventArgs.UserDataFolder`.
-
-### Requirement: Plugin SDK v5
-
-The Plugin SDK API baseline SHALL be `5.0.0`. SDK v4 plugins are treated as incompatible until rebuilt.
-
-The SDK SHALL keep the existing public UI extension shape, including `SettingsPageBase` and Avalonia `Control` based desktop components.
-
-### Requirement: Launcher data location stability
-
-Launcher data location configuration SHALL be read from a fixed bootstrap Launcher data directory so resolving the selected data root cannot recursively require resolving itself.
-
-### Requirement: OOBE state compatibility
-
-The Launcher SHALL read current OOBE state from the resolved `Launcher/state` directory and SHALL continue to migrate the legacy `.launcher/state/first_run_completed` marker.
-
-## Acceptance
-
-- `dotnet build LanMountainDesktop.slnx -c Debug` completes with 0 errors.
-- `OobeStateServiceTests` pass.
-- Full `dotnet test LanMountainDesktop.slnx -c Debug` no longer aborts from `DataLocationResolver` recursion.
-- Plugin template defaults to SDK package version `5.0.0` and manifest `apiVersion` `5.0.0`.
-- Current developer documentation points to SDK v5 and Avalonia 12.

-# 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
-
-- 将设置窗口改为独立顶层窗口，始终使用自己的任务栏按钮和图标。
-- `SettingsWindowService.Open` 改为幂等的 open-or-focus；重复打开只聚焦已有窗口，并在提供目标页时切换到对应页面。
-- 移除 `Owner`、锚点定位和 `Toggle` 语义；首次打开按参考屏幕居中，关闭为真实关闭。
-- 桌面壳的“回到 Windows”、最小化到托盘/任务栏、滑入滑出动画，只影响 `MainWindow`，不会影响设置窗口。
-- 统一桌面、托盘、IPC、组件库等设置入口，全部走 `OpenIndependentSettingsModule`。
-- 设置页文案明确“在任务栏显示图标”只控制桌面主窗口；设置窗口始终保留独立任务栏图标。

-## Impact
-
-- Affected code:
-  - `LanMountainDesktop/Services/Settings/SettingsWindowService.cs`

-## 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

-- **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。
-
-#### Scenario: 回到 Windows 时设置窗口保持可见
-- **WHEN** 主窗口执行“回到 Windows”并隐藏到托盘或最小化到任务栏
-- **THEN** 设置窗口保持当前可见状态
-- **AND THEN** 设置窗口不会跟随主窗口一起隐藏、最小化或重定位
-
-#### Scenario: 桌面滑入滑出动画不作用于设置窗口
-- **WHEN** 启用了滑入滑出动画并触发主窗口退场或入场
-- **THEN** 只有主窗口参与动画
-- **AND THEN** 设置窗口不会消失，也不会跟随主窗口做进出场动画
-
-### Requirement: 关闭设置窗口时真实销毁实例
-
-系统 SHALL 在用户关闭设置窗口时真实关闭该窗口实例。
-
-#### Scenario: 关闭后再次打开
-- **WHEN** 用户点击设置窗口右上角关闭按钮
-- **THEN** 当前设置窗口实例被关闭并销毁
-- **AND THEN** 下次再次打开设置时创建新的设置窗口实例
-- **AND THEN** 新窗口按参考屏幕居中显示

-# 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 Coordinator And Always-On Tray Addendum
-
-## Launcher-to-launcher coordination
-
-- Launcher reserves startup ownership in `%LocalAppData%\LanMountainDesktop\.launcher\state\startup-attempt.json` before it starts the host process.
-- The reserved record includes `CoordinatorPid`, `CoordinatorPipeName`, `HeartbeatAtUtc`, `PublicIpcConnected`, `ShellStatus`, and `ReservedBeforeHostStart`.
-- Only the active coordinator may call `Process.Start()` for the host. Secondary Launchers attach to the coordinator pipe and request desktop activation or status.
-- If the coordinator heartbeat is newer than `10s` and the coordinator pid is alive, a new Launcher must not take over.
-- If the coordinator is stale, the next Launcher may take over the same pending attempt instead of creating a second host attempt.
-- Normal launches probe Host Public IPC first. If a host is already running, Launcher activates that instance and exits without starting another host.
-
-## Finer shell status
-
-- Public shell IPC exposes `GetShellStatusAsync()`, `ActivateMainWindowWithStatusAsync()`, `EnsureTrayReadyAsync()`, and `EnsureTaskbarEntryAsync()`.
-- `PublicShellStatus` separates process, shell state, main-window visibility, tray health, taskbar-entry health, and Public IPC readiness.
-- Launcher success/failure details must include coordinator pid, attempt id, host pid, Public IPC status, tray state, and taskbar usability when available.
-
-## Always-on tray and taskbar repair
-
-- The tray icon and menu are mandatory application-liveness indicators and are not controlled by user settings.
-- Tray watchdog starts during shell initialization and keeps running until application exit.
-- `ShowInTaskbar=true` means hidden/background states prefer `MinimizedToTaskbar`; it never disables the tray.
-- `ShowInTaskbar=false` is the only mode that may enter pure `TrayOnly`, and only after `TrayReady`.
-- When taskbar entry is requested but missing, shell repair recreates or shows the main window minimized with `ShowInTaskbar=true` while keeping the tray visible.
-
-## Regression coverage
-
-- Unit tests cover active coordinator rejection, stale heartbeat takeover, and host-pid assignment after a reserved attempt.
-- Manual QA still needs multi-process Launcher concurrency and real tray loss simulation on Windows.

-# 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。

-- 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。

-# Launcher Slow-Startup And Startup Visual Addendum
-
-## New startup timing contract
-
-- `30s` is a soft timeout, not a failure threshold.
-- After `30s`, if the desktop process is still alive or Public IPC is connected, Launcher must stay in a waiting state and must not start another host process.
-- `120s` is the hard timeout.
-- Before returning `desktop_not_visible`, Launcher must attempt one foreground recovery through `ActivateMainWindowAsync()`.
-
-## Startup attempt de-duplication
-
-- Launcher persists the current startup attempt in `%LocalAppData%\LanMountainDesktop\.launcher\state\startup-attempt.json`.
-- A second Launcher process must attach to a live pending attempt instead of calling `Process.Start()` again.
-- Closing the splash window does not cancel startup; it transitions the attempt into detached waiting and preserves recovery state for the next Launcher run.
-
-## Startup visual modes
-
-- `EnableSlideTransition = true` forces `StartupVisualMode.SlideSplash` and automatically disables fade.
-- `EnableSlideTransition = false && EnableFadeTransition = false` resolves to `StartupVisualMode.StaticSplash`.
-- `EnableSlideTransition = false && EnableFadeTransition = true` resolves to `StartupVisualMode.Fade`.
-
-## UX safeguards
-
-- If the host process is still alive at failure time, the failure dialog must prefer:
-  - `Activate`
-  - `Wait`
-  - `Open Logs`
-  - `Exit`
-- Retry is only valid when Launcher is not about to create a duplicate desktop process.
-
-## Launcher coordinator guard
-
-- Startup attempts are now reserved before host launch, so concurrent Launchers cannot all reach `Process.Start()`.
-- A live coordinator is identified by `CoordinatorPid`, `CoordinatorPipeName`, and a heartbeat newer than `10s`.
-- Secondary Launchers send `activate-desktop` or `attach` to the coordinator pipe and then exit with the coordinator status.
-- If Host Public IPC is already available during a normal launch, Launcher activates the existing desktop and does not start a new host process.
-- Public shell status now reports tray readiness and taskbar-entry usability separately, allowing Launcher to distinguish "running but hidden" from "not recoverable".

-# Tray Menu Shutdown Addendum
-
-## Requirements
-
-- Tray menu `Exit App` must commit an irreversible host shutdown request.
-- Once shutdown is committed, tray menu actions must not reopen the desktop, settings window, or component library.
-- Shutdown cleanup must release Public IPC, plugin runtime, tray icon, fused desktop edit UI, telemetry resources, and the single-instance lock before the forced-exit deadline.
-- Forced process termination must be scheduled when the shutdown request is accepted, not only after Avalonia lifetime exit.
-- Restart must preserve `RestartRequested` intent and must not route through an exit path that overwrites it.
-- Fused desktop component library menu activation must reuse the existing library window and must exit edit mode if opening fails.
-
-## Acceptance
-
-- Selecting `Exit App` from the tray leaves no background host process and allows a later Launcher start to acquire the single-instance lock.
-- Selecting `Restart App` starts the Launcher or upgrade helper once, then shuts down the old host as a restart.
-- Repeated tray clicks during shutdown are ignored and logged.
-- Repeated component-library clicks focus the existing window instead of opening duplicates.

-# 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。
