-# 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)

-            - `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)
+            - **releases.win.json** - Velopack release feed consumed by the launcher update flow
+            - **LanMountainDesktop-<version>-full.nupkg** - full package
+            - **LanMountainDesktop-<version>-delta.nupkg** - delta package (when available)
+
+            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.

-# 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`
-  - `LanMountainDesktop/App.axaml.cs`
-  - `LanMountainDesktop/Views/MainWindow.axaml.cs`
-  - `LanMountainDesktop/Views/MainWindow.ComponentSystem.cs`
-  - `LanMountainDesktop/Views/FusedDesktopComponentLibraryControl.axaml.cs`
-  - `LanMountainDesktop/Views/SettingsPages/GeneralSettingsPage.axaml`
-- Affected behavior:
-  - 设置窗口生命周期
-  - 设置入口一致性
-  - 任务栏图标与桌面壳显示边界

-
-## 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。
-
-#### 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 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。

-- The current production OOBE state format is a per-user JSON file at `%LOCALAPPDATA%\LanMountainDesktop\.launcher\state\oobe-state.json`.
-- `first_run_completed` remains legacy compatibility data only.
-- Same-user reinstall or upgrade should not re-enter OOBE.

-# 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`
-  - `files-linux-x64.json` / `.sig` / `update-linux-x64.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。

-# VeloPack Update Integration (Deprecated)
+# VeloPack Update Integration
 
-## Status
+## Goal
+Switch incremental package generation and release assets to VeloPack native outputs while keeping Launcher as the update installer and rollback authority.
 
-This spec is deprecated and superseded by `.trae/specs/pdc-incremental-migration/`.
+## Requirements
+- CI/release pipeline produces `releases.win.json` and `*.nupkg` assets for Windows x64.
+- Launcher can detect pending VeloPack payload in `.launcher/update/incoming`.
+- Launcher applies update into new `app-*` deployment and preserves rollback snapshot behavior.
+- Existing launcher responsibilities (OOBE/startup/plugin upgrade) remain unchanged.
 
-## Deprecation Reason
-
-- VeloPack native package generation introduced unstable release blocking (version format coupling and platform divergence).
-- The project has switched back to signed FileMap incremental assets as the primary update path.
-- Launcher remains the update installer/rollback authority; packaging and distribution are being migrated to PDC/S3-compatible flows.
-
-## Migration Note
-
-Use `.trae/specs/pdc-incremental-migration/spec.md` as the active authority for incremental update implementation and acceptance.
+## Acceptance
+- Build and quality workflows pass after migration changes.
+- Release workflow publishes VeloPack assets.
+- Launcher `update apply` succeeds with VeloPack full package payload.
+- Manual rollback still works after a VeloPack-based update.
