+
+### 1.2 双渠道更新策略
+
+| 渠道 | 机制 | 使用场景 | 流程 |
+|------|------|---------|------|
+| **Google Play** | Google Play Core Library | 正式发布、应用商店 | UpdateService → GooglePlayUpdater → InAppUpdate API |
+| **Self-Hosted** | 自定义APK下载 | 侧载安装、企业分发、中国市场 | UpdateService → SelfHostedUpdater → VersionChecker → DownloadManager |
+
+应用通过 `AppMarketDetector.isFromAppMarket()` 检测安装来源，应用市场安装的版本会跳转到 Play Store，侧载版本使用自托管下载。
+
+---
+
+## 2. 后端架构 (Admin Service)
+
+### 2.1 API 端点
+
+#### 公开端点 (无需认证)
+
+| 端点 | 方法 | 用途 |
+|------|------|------|
+| `/api/app/version/check` | GET | 移动端检查更新 (推荐) |
+| `/api/v1/versions/check-update` | GET | 检查更新 (兼容端点) |
+| `/api/v1/health` | GET | 健康检查 |
+| `/uploads/:filename` | GET | 下载APK文件 |
+
+#### 管理员端点 (需要认证)
+
+| 端点 | 方法 | 用途 |
+|------|------|------|
+| `/api/v1/versions` | GET | 获取版本列表 |
+| `/api/v1/versions` | POST | 创建新版本 (URL方式) |
+| `/api/v1/versions/upload` | POST | 上传APK并创建版本 |
+| `/api/v1/versions/:id` | GET | 获取单个版本详情 |
+| `/api/v1/versions/:id` | PUT | 更新版本信息 |
+| `/api/v1/versions/:id` | DELETE | 删除版本 |
+| `/api/v1/versions/:id/toggle` | PATCH | 启用/禁用版本 |
+
+### 2.2 移动端检查更新 API (推荐)
+
+此端点专为移动端设计，返回格式与 Flutter 应用的 `VersionInfo` 模型完全兼容。
+
+**请求:**
+```
+GET /api/app/version/check?platform=android&current_version=1.0.0&current_version_code=100
+```
+

+  "updatedAt": "2025-12-02T10:00:00Z"
+}
+```
+
+### 2.4 数据验证规则
+
+| 字段 | 类型 | 验证规则 |
+|------|------|---------|
+| `platform` | enum | `android` \| `ios` |
+| `versionCode` | number | 1 ~ 2147483647 |
+| `versionName` | string | 语义化版本格式: `X.Y.Z` |
+| `buildNumber` | string | 非空字符串 |

+| `fileSha256` | string | 64位十六进制字符 |
+| `changelog` | string | 非空字符串 |
+| `minOsVersion` | string | 格式: `X.Y` 或 `X.Y.Z` |
+
+### 2.5 数据库表结构
+
+```sql
+CREATE TYPE "Platform" AS ENUM ('ANDROID', 'IOS');
+
+CREATE TABLE "app_versions" (
+    id              UUID PRIMARY KEY,
+    platform        Platform NOT NULL,
+    versionCode     INTEGER NOT NULL,
+    versionName     TEXT NOT NULL,
+    buildNumber     TEXT NOT NULL,

+    updatedBy       TEXT
+);
+
+CREATE INDEX idx_app_versions_platform_enabled ON "app_versions"(platform, isEnabled);
+CREATE INDEX idx_app_versions_platform_code ON "app_versions"(platform, versionCode);
+```
+
+---
+
+## 3. 移动端架构 (Flutter)
+
+### 3.1 初始化配置
+
+```dart
+// lib/bootstrap.dart
+const String _apiBaseUrl = 'https://api.rwadurian.com';
+
+UpdateService().initialize(
+  UpdateConfig.selfHosted(
+    apiBaseUrl: _apiBaseUrl,
+    enabled: true,
+    checkIntervalSeconds: 86400,  // 24小时
+  ),
+);
+```
+
+### 3.2 核心组件
+
+| 组件 | 文件路径 | 职责 |
+|------|---------|------|
+| `UpdateService` | `lib/core/updater/update_service.dart` | 统一入口，管理更新流程 |
+| `VersionChecker` | `lib/core/updater/version_checker.dart` | 与后端API通信，获取最新版本 |
+| `DownloadManager` | `lib/core/updater/download_manager.dart` | 下载APK，验证SHA256 |
+| `ApkInstaller` | `lib/core/updater/apk_installer.dart` | 调用系统安装APK |
+| `SelfHostedUpdater` | `lib/core/updater/channels/self_hosted_updater.dart` | 自托管更新完整流程 |
+
+### 3.3 版本信息模型
+
+```dart
+class VersionInfo extends Equatable {
+  final String version;           // "1.0.1"
+  final int versionCode;          // 101
+  final String downloadUrl;       // APK下载URL
+  final int fileSize;             // 字节数
+  final String fileSizeFriendly;  // "50.0 MB"
+  final String sha256;            // SHA-256校验和
+  final bool forceUpdate;         // 强制更新标志
+  final String? updateLog;        // 更新日志
+  final DateTime releaseDate;     // 发布日期
+}
+```
+
+### 3.4 更新检查流程
+
+```
+App启动 (SplashPage)
+    ↓
+UpdateService.checkForUpdate(context)
+    ↓
+VersionChecker.fetchLatestVersion()
+    ├─ 获取当前版本: PackageInfo.fromPlatform()
+    └─ 请求后端: GET /api/v1/versions/check-update
+    ↓
+比较 latestVersionCode > currentVersionCode ?
+    ↓
+显示更新对话框
+    ├─ 普通更新: 显示 [稍后] [立即更新]
+    └─ 强制更新: 只显示 [立即更新], 禁止关闭对话框
+```
+
+### 3.5 下载与安装流程
+
+```
+用户点击"立即更新"
+    ↓
+显示下载进度对话框
+    ↓
+DownloadManager.downloadApk()
+    ├─ 验证HTTPS URL
+    ├─ 下载到应用私有目录
+    ├─ 显示下载进度
+    └─ 验证SHA256校验和
+    ↓
+ApkInstaller.installApk(apkFile)
+    ├─ 请求安装权限 (Android 8.0+)
+    └─ 调用系统安装界面
+    ↓
+用户完成安装，应用重启
+```
+
+---
+
+## 4. 安全机制
+
+| 安全措施 | 实现位置 | 说明 |
+|---------|---------|------|
+| **HTTPS强制** | DownloadManager | 只接受 `https://` 开头的URL |
+| **SHA256校验** | DownloadManager | 下载后验证文件完整性 |
+| **文件大小限制** | FileSize值对象 | 最大2GB |
+| **版本号验证** | VersionCode值对象 | 1 ~ 2147483647 |
+| **无外部存储权限** | 应用私有目录 | 使用 `getApplicationDocumentsDirectory()` |
+| **安装权限请求** | ApkInstaller | Android 8.0+ 需要 `INSTALL_UNKNOWN_APPS` 权限 |
+| **管理员认证** | Bearer Token | 创建/修改版本需要认证 |
+
+---
+
+## 5. 管理员操作指南
+
+### 5.1 发布新版本流程
+
+```bash
+# 1. 构建Release APK
+cd android
+./gradlew assembleRelease
+
+# 2. 计算SHA256校验和
+sha256sum app/build/outputs/apk/release/app-release.apk
+# 输出: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
+
+# 3. 上传APK到文件服务器 (选择以下任一方式)
+# 阿里云OSS
+aliyun oss cp app-release.apk oss://bucket/app-v1.0.1.apk
+
+# AWS S3
+aws s3 cp app-release.apk s3://bucket/app-v1.0.1.apk
+
+# 4. 调用API创建版本
+curl -X POST https://api.rwadurian.com/api/v1/versions \
+  -H "Authorization: Bearer <admin-token>" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "platform": "android",
+    "versionCode": 101,
+    "versionName": "1.0.1",
+    "buildNumber": "202512021200",
+    "downloadUrl": "https://cdn.example.com/app-v1.0.1.apk",
+    "fileSize": "52428800",
+    "fileSha256": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
+    "changelog": "1. 修复登录问题\n2. 性能优化",
+    "isForceUpdate": false,
+    "minOsVersion": "5.0"
+  }'
+```
+
+### 5.2 启用/禁用版本
+
+```bash
+# 禁用版本
+curl -X PATCH https://api.rwadurian.com/api/v1/versions/{id}/toggle \
+  -H "Authorization: Bearer <admin-token>" \
+  -H "Content-Type: application/json" \
+  -d '{"isEnabled": false}'
+
+# 启用版本
+curl -X PATCH https://api.rwadurian.com/api/v1/versions/{id}/toggle \
+  -H "Authorization: Bearer <admin-token>" \
+  -H "Content-Type: application/json" \
+  -d '{"isEnabled": true}'
+```
+
+### 5.3 设置强制更新
+
+```bash
+curl -X PUT https://api.rwadurian.com/api/v1/versions/{id} \
+  -H "Authorization: Bearer <admin-token>" \
+  -H "Content-Type: application/json" \
+  -d '{"isForceUpdate": true}'
+```
+
+---
+
+## 6. 版本号约定
+
+### 6.1 versionCode vs versionName
+
+| 属性 | 类型 | 用途 | 示例 |
+|------|------|------|------|
+| `versionCode` | 整数 | 用于比较新旧版本，必须递增 | 101, 102, 200 |
+| `versionName` | 字符串 | 用户可见的版本号 | "1.0.1", "2.0.0" |
+
+### 6.2 版本号递增规则
+
+```
+versionCode 计算公式建议:
+  major * 10000 + minor * 100 + patch
+
+示例:
+  1.0.0 → 10000
+  1.0.1 → 10001
+  1.1.0 → 10100
+  2.0.0 → 20000
+```
+
+### 6.3 Android 配置
+
+```groovy
+// android/app/build.gradle
+android {
+    defaultConfig {
+        versionCode 10001        // 用于更新比较
+        versionName "1.0.1"      // 用户可见
+    }
+}
+```
+
+### 6.4 Flutter 配置
+
+```yaml
+# pubspec.yaml
+version: 1.0.1+10001
+# 格式: versionName+versionCode
+```
+
+---
+
+## 7. 错误处理
+
+### 7.1 后端错误码
+
+| HTTP状态码 | 错误类型 | 说明 |
+|-----------|---------|------|
+| 400 | Bad Request | 请求参数验证失败 |
+| 401 | Unauthorized | 未提供或无效的认证令牌 |
+| 404 | Not Found | 版本不存在 |
+| 409 | Conflict | 版本号已存在 |
+| 500 | Internal Server Error | 服务器内部错误 |
+
+### 7.2 移动端错误处理
+
+```dart
+try {
+  final versionInfo = await versionChecker.checkForUpdate();
+  if (versionInfo != null) {
+    await showUpdateDialog(context, versionInfo);
+  }
+} on DioException catch (e) {
+  // 网络错误，静默失败，不影响用户使用
+  debugPrint('Update check failed: ${e.message}');
+} catch (e) {
+  debugPrint('Unexpected error: $e');
+}
+```

+
+## 10. 常见问题
+
+### Q1: 如何实现灰度发布？
+
+目前系统不支持灰度发布。可通过以下方式扩展:
+- 添加 `rolloutPercentage` 字段
+- 基于设备ID哈希值判断是否推送更新
+
+### Q2: 如何支持多语言更新日志？
+
+可将 `changelog` 字段改为 JSON 格式:
+```json
