+# LanMountainDesktop AI Guide
+
+本文件是 AI 助手进入本仓库时的第一入口。面向 Codex、Cursor、Trae 等工具，目标是减少重复探索，快速定位权威文档、关键目录和执行约束。
+
+## 1. 项目目标与仓库边界
+
+- 本仓库是阑山桌面桌面宿主、宿主侧插件运行时、Plugin SDK、共享契约与基础外观/设置能力的权威来源。
+- 不要把插件市场元数据、开发者门户或官方示例插件实现当作本仓库内容维护。
+- 市场和生态材料属于兄弟仓库 `LanAirApp`。
+- 官方示例插件属于独立仓库 `LanMountainDesktop.SamplePlugin`。
+
+边界详情看：
+
+- `docs/ECOSYSTEM_BOUNDARIES.md`
+- `docs/ARCHITECTURE.md`
+
+## 2. 关键目录地图
+
+- `LanMountainDesktop/`: 主宿主应用，包含 UI、服务、组件系统、主题与插件运行时接入
+- `LanMountainDesktop/ComponentSystem/`: 内置组件定义、注册、扩展加载
+- `LanMountainDesktop/plugins/`: 宿主侧插件运行时、安装与 market 集成
+- `LanMountainDesktop/Views/` and `ViewModels/`: UI 页面、窗口与视图模型
+- `LanMountainDesktop/Services/`: 设置、遥测、启动、持久化、业务服务
+- `LanMountainDesktop.PluginSdk/`: 插件 SDK 公共接口和默认打包行为
+- `LanMountainDesktop.Shared.Contracts/`: 宿主/插件共享契约
+- `LanMountainDesktop.Tests/`: 宿主与 SDK 测试
+- `.trae/specs/`: feature 级规格、任务拆解和验收清单
+
+更详细映射看 `docs/ai/CODEBASE_MAP.md`。
+
+## 3. 常用命令
+
+```bash
+dotnet restore
+dotnet build LanMountainDesktop.slnx -c Debug
+dotnet run --project LanMountainDesktop/LanMountainDesktop.csproj
+dotnet test LanMountainDesktop.slnx -c Debug
+```
+
+插件本地包生成：
+
+```powershell
+./scripts/Pack-PluginPackages.ps1
+```
+
+## 4. 改动前后必做检查
+
+改动前：
+
+- 先确认需求是否已经在 `.trae/specs/` 中存在
+- 先确认产品、架构、专题规范分别以哪份文档为准
+- 避免沿用旧根目录产品文档中的过时事实
+
+改动后：
+
+- 至少检查构建和与改动相关的测试
+- 如果行为、流程、边界或命令变化，更新对应文档
+- 如果是新功能或行为调整，补齐或更新 `.trae/specs/<feature>/`
+
+## 5. 高频区域注意事项
+
+### UI
+
+- 主题、资源和视觉语义优先遵守 `docs/VISUAL_SPEC.md` 与 `docs/CORNER_RADIUS_SPEC.md`
+- 设置页相关改动通常同时落在 `Views/`、`ViewModels/`、`Services/` 和 `.trae/specs/`
+- UI 启动与窗口生命周期主线在 `Program.cs` 和 `App.axaml.cs`
+
+### 插件
+
+- SDK 公共 API 以 `LanMountainDesktop.PluginSdk/` 为准
+- 共享契约以 `LanMountainDesktop.Shared.Contracts/` 为准
+- market 数据来源默认是兄弟仓库 `..\\LanAirApp`
+- 迁移或 breaking change 优先同步 `docs/PLUGIN_SDK_V4_MIGRATION.md`
+
+### 设置与主题
+
+- 设置持久化和 scope 变化优先检查 `LanMountainDesktop.Settings.Core/`
+- 外观、圆角、主题资源优先检查 `LanMountainDesktop.Appearance/` 与专题规范
+
+## 6. 权威来源
+
+- 产品定位：`docs/PRODUCT.md`
+- 架构与模块职责：`docs/ARCHITECTURE.md`
+- 运行、构建、测试、打包：`docs/DEVELOPMENT.md`
+- feature 规格：`.trae/specs/`
+- 视觉规范：`docs/VISUAL_SPEC.md`
+- 圆角规范：`docs/CORNER_RADIUS_SPEC.md`
+- 生态边界：`docs/ECOSYSTEM_BOUNDARIES.md`
+- SDK v4 迁移：`docs/PLUGIN_SDK_V4_MIGRATION.md`
+
+如果多个文档都提到同一件事，以 `docs/ai/DOC_SOURCES.md` 列出的权威来源为准。

-```
-
----
-
-## 4. 数据模型变更
-
-### 4.1 WallpaperMediaType 枚举简化
-
-```
-变更前: None | Image | Video
-变更后: None | Image
-```
-
-### 4.2 设置存储兼容性
-
-现有用户设置中如果包含 `Type: "Video"` 的壁纸配置：
-- 应用将无法识别该类型
-- 将回退到纯色背景
-- 用户需要重新选择图片壁纸
-
----
-
-## 5. 风险评估
-
-### 5.1 潜在风险
-
-| 风险 | 影响 | 缓解措施 |
-|------|------|----------|
-| 现有视频壁纸用户设置失效 | 中 | 应用会自动回退到纯色背景 |
-| 遗漏的视频相关代码引用 | 低 | 编译器会报告未定义类型错误 |
-| 本地化键遗漏 | 低 | 运行时会显示键名而非翻译文本 |
-
-### 5.2 回滚策略
-
-如需回滚，可通过 Git 恢复以下文件：
-- LanMountainDesktop.csproj
-- MainWindow.axaml / .axaml.cs
-- MainWindow.SettingsHardCut.Stubs.cs
-- AppearanceThemeService.cs
-- WallpaperSettingsPage.axaml
-- WallpaperSettingsPageViewModel.cs
-- SettingsContracts.cs
-- SettingsDomainServices.cs
-- zh-CN.json

-# 移除视频壁纸功能规格说明书
-
-## Why
-
-当前 LanMountainDesktop 项目包含视频壁纸功能，该功能引入了以下复杂性和依赖：
-1. 引入了 LibVLCSharp.Avalonia、VideoLAN.LibVLC.Windows、VideoLAN.LibVLC.Mac 等重型依赖
-2. 在主窗口中残留大量视频壁纸相关代码和字段
-3. 在设置页面中保留了视频类型选择器和相关 UI 元素
-4. 在本地化文件中保留了视频壁纸相关文本
-5. 增加了应用复杂度和维护成本
-
-用户决定移除该功能以简化代码库。
-

+# LanMountainDesktop.PluginSdk
+
+Official SDK package for LanMountainDesktop plugins.
+
+## Includes
+
+- `IPlugin`/`PluginBase` entry abstractions
+- `PluginManifest` and shared contract declarations
+- desktop component registration extensions
+- plugin runtime context and host service abstractions
+- build-transitive packaging targets for `.laapp` output
+
+## Quick Start
+
+```xml
+<ItemGroup>
+  <PackageReference Include="LanMountainDesktop.PluginSdk" Version="4.0.0" />
+</ItemGroup>
+```
+
+Create `plugin.json` in your plugin project root, then run `dotnet build` to produce both build output and a `.laapp` package.
