-# LanMountainDesktop
-
-> 你的桌面，不止一面。
-
-`LanMountainDesktop` 是一个基于 Avalonia 的桌面壳层项目，目标不是“做一个启动器”，而是把桌面变成可编排的信息与交互空间。
-
-## 项目定位
-- 以网格化布局组织桌面组件，支持多页桌面与组件自由摆放。
-- 提供顶部状态栏 + 底部任务栏的桌面框架，强调信息密度与可读性平衡。
-- 通过主题色、日夜模式、玻璃视觉与动画系统，形成统一的视觉语言。
-- 通过组件注册机制与 JSON 扩展入口，让桌面能力可持续扩展。
-
-## 核心能力
-- 桌面组件系统：天气、时钟、计时器、课程表、日历、白板、音乐控制、学习环境等组件可组合使用。
-- 壁纸系统：支持图片与视频壁纸，并可在设置中实时预览。
-- 主题系统：支持日夜模式、主题色与调色联动（Monet 风格色板）。
-- 个性化设置：网格密度、状态栏间距、任务栏布局、语言与时区等可持久化配置。
-- 本地化：内置 `zh-CN` 与 `en-US` 资源。
-
-## 工程结构
-- `LanMountainDesktop/`：桌面端主程序（Avalonia）。
-- `LanMountainDesktop.RecommendationBackend/`：推荐内容后端服务（ASP.NET Core Minimal API）。
-- `docs/`：视觉与圆角等规范文档。
-- `LanMountainDesktop/ComponentSystem/`：组件定义、注册、放置规则与扩展入口。
-
-## 技术栈
-- .NET 10（`net10.0`）
-- Avalonia 11
-- FluentAvalonia + FluentIcons.Avalonia
-- LibVLCSharp（用于视频相关能力）
-- WebView.Avalonia（嵌入式网页组件能力）
-
-## 扩展机制（摘要）
-- 组件系统通过 `ComponentRegistry` 合并内置组件与扩展组件。
-- 运行时会扫描 `Extensions/Components/*.json`（相对应用输出目录）加载第三方组件清单。
-- 扩展契约与字段说明见组件系统文档：`LanMountainDesktop/ComponentSystem/README.md`。
-
-## 当前状态
-- 项目包含桌面端与推荐后端两个子项目，并在同一 `LanMountainDesktop.slnx` 工作区中维护。
-- 配置默认写入本地：`%LOCALAPPDATA%\LanMountainDesktop\settings.json`。
-- 当前体验以 Windows 为主要目标平台。
-- SDK 版本由仓库根目录 `global.json` 锁定。
-
-## 运行说明
-运行与环境准备已拆分到独立文档：[`run.md`](./run.md)

+# 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`
+- **组件圆角**：所有内置与插件组件的根边框必须使用 `{DynamicResource DesignCornerRadiusComponent}` 资源。
+- 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
+- **圆角统一**：桌面组件（Widget）必须统一使用动态资源 `DesignCornerRadiusComponent`。严禁在组件根容器使用硬编码数值或非组件级令牌（如 `Xs`, `Md` 等），以确保全局圆角缩放设置能正确应用到所有组件。
+
+## 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`
