+# 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。

-# 隐私与遥测说明
+# LanMountainDesktop 遥测隐私政策
 
-LanMountainDesktop 提供两类可选遥测能力：
+**生效日期**：2026年3月22日\
+**最后更新**：2026年3月22日
 
-- 崩溃数据上传
-- 行为数据分析
+***
 
-这两个开关默认关闭。即使两项都关闭，应用仍会在首次启动时向 PostHog 发送一次最小化的启动基线事件，用于统计用户量。
+## 引言
 
-## 默认行为
+LanMountainDesktop（以下简称"本应用"）由 灵方软件Lincube（以下简称"我们"）开发和维护。我们深知用户隐私的重要性，并致力于保护您的个人信息安全。本隐私政策旨在向您说明我们如何收集、使用、存储和保护您的数据。
 
-当“崩溃数据上传”和“行为数据分析”都关闭时：
+使用本应用即表示您同意本隐私政策的条款。如果您不同意本政策的任何部分，请停止使用本应用。
 
-- 仅首次启动会发送一次 `app_first_launch` 事件
-- 该事件只用于统计用户量
-- 事件时间由 PostHog 接入侧记录的请求时间和启动时间决定
-- 不会主动上传设备型号、操作系统细节、组件操作轨迹等详细信息
+***
 
-## 崩溃数据上传
+## 1. 数据收集范围
 
-当开启“崩溃数据上传”时，应用会把崩溃与未处理异常发送到 Sentry，用于分析稳定性问题。
+### 1.1 我们收集的数据
 
-上报内容可能包括：
+本应用提供两类可选的数据收集功能：
 
-- 异常堆栈和错误上下文
-- 应用版本与运行环境
-- 操作系统信息
-- 设备基础信息
-- 最近的日志尾部内容
+| 数据类型   | 收集方式 | 默认状态 | 用途       |
+| ------ | ---- | ---- | -------- |
+| 启动基线事件 | 自动收集 | 开启   | 统计用户量    |
+| 崩溃数据   | 用户授权 | 关闭   | 分析稳定性问题  |
+| 行为数据   | 用户授权 | 关闭   | 分析功能使用情况 |
 
-应用退出或崩溃时，会尽量补充最后一次会话和日志信息，方便定位问题。
+### 1.2 启动基线事件
 
-## 行为数据分析
+无论您是否开启其他遥测选项，本应用会在首次启动时发送一次最小化的启动基线事件（`app_first_launch`），用于统计活跃用户量。该事件仅包含：
 
-当开启“行为数据分析”时，应用会把关键行为事件发送到 PostHog，用于分析功能使用情况和会话路径。
+- 匿名安装标识符（Install ID）
+- 应用版本号
+- 启动时间戳
 
-上报内容可能包括：
+### 1.3 崩溃数据
 
-- 应用启动和退出时间
-- 会话开始与结束时间
-- 设置页打开、关闭和导航
-- 抽屉打开和关闭
-- 桌面组件的放置、移动、缩放、删除和编辑入口
+当您开启"崩溃数据上传"功能时，我们可能收集以下信息：
 
-这些事件会被转换成 PostHog 可以直接接收和分析的事件格式，方便在 PostHog 中按事件流查看用户行为。桌面端的“回放”能力通过事件时间线重建，而不是浏览器式 Session Replay。
+- **异常信息**：异常类型、错误消息、堆栈跟踪
+- **应用信息**：应用版本、构建号、运行时环境
+- **系统信息**：操作系统版本、系统架构、可用内存
+- **设备信息**：设备型号、屏幕分辨率
+- **日志信息**：应用崩溃前的最近日志记录（可能包含您在使用过程中产生的操作记录）
 
-## 身份与隐私控制
+### 1.4 行为数据
 
-应用会使用随机生成的匿名 install ID 和可刷新 telemetry ID 来区分安装与运行会话。
+当您开启"行为数据分析"功能时，我们可能收集以下信息：
 
-- 刷新 telemetry ID 只会影响后续详细遥测
-- 关闭开关后，不会继续发送对应类别的详细遥测
-- IP 只会通过 Sentry / PostHog 的服务端接入侧自然记录，不会作为自定义字段重复上报
+- **会话信息**：应用启动/退出时间、会话持续时间
+- **功能使用**：设置页面访问、抽屉操作、组件库操作
+- **组件操作**：桌面组件的放置、移动、调整大小、删除操作
+- **界面交互**：页面切换、编辑模式进入/退出
 
+***
+
+## 2. 数据使用目的
+
+我们收集的数据将用于以下目的：
+
+### 2.1 启动基线事件
+
+- 统计应用的用户数量和活跃度
+- 了解应用的安装分布情况
+
+### 2.2 崩溃数据
+
+- 诊断和修复应用崩溃问题
+- 提高应用的稳定性和可靠性
+- 识别和解决性能瓶颈
+
+### 2.3 行为数据
+
+- 了解用户如何使用本应用的功能
+- 改进用户体验和界面设计
+- 指导功能开发和优先级决策
+- 分析用户行为模式和趋势
+
+***
+
+## 3. 数据存储与传输

+## 为谁而设计
 
-## Workspace Market Resolution
+| 用户类型 | 典型场景 |
+|---------|---------|
+| 🎓 学生用户 | 课程表、自习监测、计时、天气和日常信息聚合 |
+| 💼 办公用户 | 日历、资讯、最近文档、常用工具入口 |
+| 🎨 效率爱好者 | 自由布局、主题切换、插件扩展 |
+| 🇨🇳 中文用户 | 本地化界面、农历和节假日等本地语境支持 |
 
-For local market debugging, the host resolves workspace files from the sibling repository path (`..\\LanAirApp`) instead of reading the in-repo mirror folder.
