-# 架构修复方案文档
-
-## 1. 重构目标
-
-### 1.1 核心原则
-- **单一职责**：每个模块只负责一个明确的功能
-- **依赖倒置**：高层模块不依赖低层模块，都依赖抽象
-- **开闭原则**：对扩展开放，对修改关闭
-
-### 1.2 目标架构

-```
-
-## 2. 具体修复方案
-
-### 2.1 messageManager.ts 重构方案
-
-#### 现状问题
-- 1500+行，上帝对象
-- 混合了 WebSocket、数据库、状态管理、UI通知
-- 与SQLite深度耦合
-
-#### 目标结构
-```
-src/data/
-├── datasources/
-│   ├── WebSocketClient.ts      # WebSocket连接管理
-│   └── MessageDataSource.ts    # 消息数据源
-├── repositories/
-│   └── MessageRepository.ts    # 消息仓库实现
-└── mappers/
-    └── MessageMapper.ts        # 消息数据映射
-
-src/core/
-├── entities/
-│   └── Message.ts              # 消息实体
-├── repositories/
-│   └── IMessageRepository.ts   # 仓库接口
-└── usecases/
-    ├── ProcessMessageUseCase.ts
-    ├── SyncMessagesUseCase.ts
-    └── UpdateReadReceiptUseCase.ts
-
-src/presentation/stores/
-└── messageStore.ts             # 简化的消息状态管理
-```
-
-#### 重构步骤
-1. 提取 WebSocketClient - 纯连接管理
-2. 创建 MessageRepository - 数据访问抽象
-3. 创建 UseCases - 业务逻辑
-4. 重写 messageStore - 仅负责UI状态
-5. 删除旧的 messageManager.ts
-
-### 2.2 乐观更新工具函数方案
-
-#### 现状问题
-- userStore.ts 中重复6+次相同模式
-- 代码冗余，难以维护
-
-#### 目标API
-```typescript
-// utils/optimisticUpdate.ts
-export interface OptimisticUpdateOptions<T, R> {
-  store: StoreApi<any>;
-  getCurrentState: () => T;
-  optimisticUpdate: (current: T) => T;
-  apiCall: () => Promise<R>;
-  onSuccess?: (result: R, current: T) => T;
-  onError?: (error: any, original: T) => void;
-}
-
-export async function optimisticUpdate<T, R>(
-  options: OptimisticUpdateOptions<T, R>
-): Promise<R>
-```
-
-#### 使用示例
-```typescript
-// 重构前（重复代码）
-set(state => ({ posts: updatedPosts }));
-try {
-  const result = await postService.like(postId);
-  // ...
-} catch (error) {
-  set(state => ({ posts: originalPosts }));
-}
-
-// 重构后（简洁）
-await optimisticUpdate({
-  store,
-  getCurrentState: () => store.getState().posts,
-  optimisticUpdate: (posts) => updatePostLikes(posts, postId, true),
-  apiCall: () => postService.like(postId),
-  onSuccess: (result, posts) => updatePostWithServerData(posts, result),
-});
-```
-
-### 2.3 useResponsive.ts 拆分方案
-
-#### 现状问题
-- 485行，43个导出
-- 功能混杂：断点检测、响应式值计算、平台检测
-
-#### 目标结构
-```
-src/presentation/hooks/responsive/
-├── useBreakpoint.ts           # 断点检测
-├── useResponsiveValue.ts      # 响应式值映射
-├── useOrientation.ts          # 方向检测
-├── usePlatform.ts            # 平台检测
-├── useScreenSize.ts          # 屏幕尺寸
-└── index.ts                  # 统一导出
-```
-
-#### 各Hook职责
-- `useBreakpoint`: 返回当前断点 (mobile/tablet/desktop/wide)
-- `useResponsiveValue`: 根据断点返回不同值
-- `useOrientation`: 返回 portrait/landscape
-- `usePlatform`: 返回 ios/android/web
-- `useScreenSize`: 返回 width/height
-
-### 2.4 MainNavigator 解耦方案
-
-#### 现状问题
-- 1118行，直接依赖store
-- 混合了导航配置和业务逻辑
-
-#### 目标结构
-```
-src/infrastructure/navigation/
-├── MainNavigator.tsx         # 简化后的导航器
-├── AuthNavigator.tsx         # 认证导航
-├── TabNavigator.tsx          # 标签导航
-├── navigationService.ts      # 导航服务（解耦层）
-├── navigationTypes.ts        # 类型定义
-└── hooks/
-    └── useNavigationState.ts # 导航状态hook
-```
-
-#### 解耦策略
-1. 创建 NavigationService - 提供导航操作的抽象
-2. Store通过NavigationService触发导航，而非直接操作
-3. MainNavigator只负责渲染，不处理业务逻辑
-
-### 2.5 Repository 层创建方案
-
-#### 现状问题
-- 服务层直接操作数据库
-- 没有明确的数据访问边界
-
-#### 目标结构
-```
-src/data/repositories/
-├── MessageRepository.ts      # 消息数据访问
-├── PostRepository.ts        # 帖子数据访问
-├── UserRepository.ts        # 用户数据访问
-└── interfaces/
-    ├── IMessageRepository.ts
-    ├── IPostRepository.ts
-    └── IUserRepository.ts
-```
-
-#### 职责划分
-- **Repository**: 数据访问抽象，定义接口
-- **DataSource**: 具体数据源实现（API、SQLite、Cache）
-- **Service**: 业务逻辑编排，使用Repository
-
-## 3. 实施计划
-
-### 阶段1：基础设施（第1-2天）
-- [ ] 创建目录结构
-- [ ] 实现乐观更新工具函数
-- [ ] 拆分 useResponsive hooks
-
-### 阶段2：数据层重构（第3-5天）
-- [ ] 创建 Repository 接口和实现
-- [ ] 创建 DataSource 层
-- [ ] 迁移数据库操作到 Repository
-
-### 阶段3：核心业务重构（第6-10天）
-- [ ] 重构 messageManager → UseCases + Store
-- [ ] 创建 WebSocketClient
-- [ ] 实现消息同步逻辑
-
-### 阶段4：表现层重构（第11-12天）
-- [ ] 解耦 MainNavigator
-- [ ] 重构 userStore 使用乐观更新工具
-- [ ] 更新所有屏幕组件
-
-### 阶段5：测试与优化（第13-14天）
-- [ ] 单元测试
-- [ ] 集成测试
-- [ ] 性能优化
-
-## 4. 风险与应对
-
-| 风险 | 影响 | 应对措施 |
-|-----|------|---------|
-| 重构引入bug | 高 | 每个模块重构后必须测试，保持API兼容 |
-| 开发时间超期 | 中 | 分阶段交付，优先核心功能 |
-| 团队成员不熟悉新架构 | 中 | 编写详细文档，代码审查 |
-| 性能下降 | 低 | 添加性能监控，及时优化 |
-
-## 5. 验收标准
-
-- [ ] messageManager.ts 被删除，功能拆分到多个小模块
-- [ ] userStore.ts 中无重复乐观更新代码
-- [ ] useResponsive.ts 拆分为5+个专注hook
-- [ ] MainNavigator.tsx 行数 < 300
-- [ ] 所有单元测试通过
-- [ ] 无TypeScript错误
-- [ ] 性能不劣化（启动时间、内存占用）

-## 一、Messages模块架构分析
-
-### 1.1 架构层次结构
-
-Messages模块采用了**清晰的分层架构**，各层职责明确：

-└─────────────────────────────────────────────────────────────┘
-```
-
-### 1.2 核心组件详解
-
-#### 1.2.1 领域实体层 (Core/Entities)
-- **Message.ts**: 定义消息、会话、群通知等核心领域模型
-- 包含工厂函数：`createMessage`, `createConversation`
-- 包含业务逻辑函数：`isMessageFromCurrentUser`, `shouldIncrementUnread`, `buildTextContent`
-
-#### 1.2.2 用例层 (Core/UseCases)
-- **ProcessMessageUseCase**: 核心业务逻辑编排器
-  - 订阅SSE事件（chat, group_message, read, recall, typing, group_notice等）
-  - 消息去重处理（processedMessageIds Set）
-  - 已读状态保护（pendingReadMap + 版本号机制）
-  - 用户信息缓存与去重请求（pendingUserRequests Map）
-  - 事件发布订阅模式（subscribers Set）
-
-#### 1.2.3 仓库层 (Data/Repositories)
-- **IMessageRepository**: 定义数据访问接口
-  - 消息操作：getMessages, saveMessage, updateMessageStatus, markAsRead
-  - 会话操作：getConversations, saveConversation, updateUnreadCount
-  - 同步操作：syncMessages, getServerLastSeq
-
-- **MessageRepository**: 实现接口
-  - 封装SQLite数据库操作
-  - 消息与CachedMessage的转换
-
-#### 1.2.4 映射器层 (Data/Mappers)
-- **MessageMapper**: 数据转换
-  - `fromApiResponse`: API响应 → 应用模型
-  - `fromDbRecord`: 数据库记录 → 应用模型
-  - `toDbRecord`: 应用模型 → 数据库记录
-  - `toApiRequest`: 应用模型 → API请求
-  - 创建消息片段：`createTextSegment`, `createImageSegment`
-
-#### 1.2.5 差异计算基础设施 (Infrastructure/Diff)
-- **MessageDiffCalculator**: 消息列表差异计算
-  - 计算added, updated, deleted, moved, unchanged
-  - 变化比例检测（changeRatio > 0.5 时触发重置）
-  - 增量差异计算（基于缓存）
-
-- **MessageUpdateBatcher**: 批量更新处理器
-  - 16ms批量间隔（约60fps）
-  - 去重和合并更新
-  - 100ms最大等待时间
-  - 统计信息：totalBatches, totalUpdates, averageBatchSize
-
-- **types.ts**: 完整的类型定义
-  - MessageUpdateType枚举：ADD, UPDATE, DELETE, MOVE, BATCH_*
-  - DiffResult, DiffConfig等接口
-
-#### 1.2.6 Hook层
-- **useDifferentialMessages**: 差异更新Hook
-  - 集成DiffCalculator和Batcher
-  - 自动处理批量更新
-  - 提供flush, reset, forceUpdate方法
-  - 支持配置：enableDiff, enableBatching, maxMessageCount, changeRatioThreshold
-
-### 1.3 数据流
-
-```
-SSE事件 → ProcessMessageUseCase → 事件发布 → useChatScreen → useDifferentialMessages
-                                    ↓                    ↓
-                              MessageRepository      差异计算 + 批量处理
-                                    ↓                    ↓
-                              SQLite数据库           优化后的消息列表
-```
-
-### 1.4 状态管理方式
-
-- **发布-订阅模式**：ProcessMessageUseCase作为事件中心
-- **本地SQLite缓存**：消息持久化存储
-- **内存状态**：通过Hook返回，组件直接消费
-- **差异更新**：通过MessageDiffCalculator + MessageUpdateBatcher减少重渲染
-
----
-
-## 二、PostService/Manager架构分析
-
-### 2.1 架构层次结构
-
-Post模块采用了**扁平化架构**，Service和Manager层职责混合：
-
-```
-┌─────────────────────────────────────────────────────────────┐
-│                      表现层 (Screens)                        │
-│  HomeScreen, PostDetailScreen, CreatePostScreen              │
-├─────────────────────────────────────────────────────────────┤
-│                      Hooks层                                │
-│  useCursorPagination (通用), usePrefetch                     │
-├─────────────────────────────────────────────────────────────┤
-│                      Store层 (Zustand)                      │
-│  useUserStore (直接操作状态), postManager (缓存管理)         │
-├─────────────────────────────────────────────────────────────┤
-│                      Service层                              │
-│  postService (API调用 + 状态更新)                            │
-├─────────────────────────────────────────────────────────────┤
-│                      数据源                                 │
-│  API (直接调用)                                             │
-└─────────────────────────────────────────────────────────────┘
-```
-
-### 2.2 核心组件详解
-
-#### 2.2.1 Service层 (Services)
-- **postService.ts**: 帖子服务
-  - CRUD操作：getPosts, getPost, createPost, updatePost, deletePost
-  - 互动操作：likePost, unlikePost, favoritePost, unfavoritePost
-  - 分页支持：传统分页 + 游标分页
-  - **问题**：直接操作useUserStore（违反分层原则）
-
-#### 2.2.2 Manager层 (Stores)
-- **postManager.ts**: 帖子缓存管理器
-  - 继承CacheBus（发布订阅基类）
-  - 内存缓存：listCache, detailCache
-  - 请求去重：pendingRequests Map
-  - TTL管理：LIST_TTL=30s, DETAIL_TTL=60s
-  - 后台刷新机制
-
-#### 2.2.3 Store层 (Zustand)
-- **useUserStore**: 用户状态存储
-  - 直接存储posts数组
-  - 帖子操作副作用直接修改状态
-  - 混合了用户数据和帖子数据
-
-#### 2.2.4 映射器层 (Data/Mappers)
-- **PostMapper**: 数据转换
-  - `fromApiResponse`: API响应 → 应用模型
-  - `fromApiResponseList`: 批量转换
-  - `toApiRequest`: 应用模型 → API请求
-  - 相比MessageMapper缺少数据库记录转换方法
-
-### 2.3 数据流
-
-```
-HomeScreen → useCursorPagination → postService.getPostsCursor
-                                    ↓
-                              useUserStore.setState(posts)
-                                    ↓
-                              PostCard组件渲染
-```
-
-### 2.4 状态管理方式
-
-- **Zustand Store**：集中式状态管理
-- **内存缓存**：postManager提供应用级缓存
-- **请求去重**：dedupe方法防止重复请求
-- **直接修改**：postService直接调用useUserStore.setState
-
----
-
-## 三、主要架构差异
-
-### 3.1 分层复杂度
-
-| 维度 | Messages模块 | Post模块 |
-|------|-------------|---------|
-| 层次深度 | 6层（Entity→UseCase→Repository→Mapper→Hook→Screen） | 4层（Service→Store→Hook→Screen） |
-| 用例层 | 独立ProcessMessageUseCase | 无 |
-| 仓库接口 | IMessageRepository抽象接口 | 无 |
-| 基础设施 | Diff模块（Calculator + Batcher） | 无 |
-
-### 3.2 数据持久化
-
-| 维度 | Messages模块 | Post模块 |
-|------|-------------|---------|
-| 本地存储 | SQLite数据库 | 无 |
-| 缓存抽象 | MessageRepository封装 | postManager内存缓存 |
-| 离线支持 | 完整 | 不支持 |
-
-### 3.3 实时更新
-
-| 维度 | Messages模块 | Post模块 |
-|------|-------------|---------|
-| 推送机制 | SSE实时推送 | 轮询/下拉刷新 |
-| 事件订阅 | ProcessMessageUseCase发布订阅 | 无 |
-| 增量更新 | MessageDiffCalculator | 无 |
-
-### 3.4 状态管理
-
-| 维度 | Messages模块 | Post模块 |
-|------|-------------|---------|
-| 管理方式 | 发布订阅 + Hook局部状态 | Zustand全局Store |
-| 状态来源 | useChatScreen, useDifferentialMessages | useUserStore |
-| 批量更新 | MessageUpdateBatcher | 无 |
-| 差异检测 | MessageDiffCalculator | 无 |
-
-### 3.5 依赖方向
-
-**Messages模块（正确）**：
-```
-Hook → UseCase → Repository → DataSource
-              ↓
-         Entity（不依赖外部）
-```
-
-**Post模块（问题）**：
-```
-Service → Store（循环依赖风险）
-   ↓
-API直接调用
-```
-
-### 3.6 核心问题总结
-
-| # | 问题 | Messages | Post |
-|---|------|---------|------|
-| 1 | 违反分层原则 | 无 | postService直接操作useUserStore |
-| 2 | 缺少UseCase层 | ProcessMessageUseCase | 无业务逻辑编排 |
-| 3 | 缺少Repository抽象 | IMessageRepository | 无数据访问接口 |
-| 4 | 无差异更新 | useDifferentialMessages | 无 |
-| 5 | 无批量处理 | MessageUpdateBatcher | 无 |
-| 6 | 无本地持久化 | SQLite | 无 |
-| 7 | 无实时推送 | SSE | 无 |
-

-## 四、对齐建议
-
-### 4.1 架构重构目标

-### 4.2 具体改造项
-
-#### 4.2.1 创建Post领域实体
-```typescript
-// src/core/entities/Post.ts
-export interface Post {
-  id: string;
-  authorId: string;
-  title: string;
-  content: string;
-  images: string[];
-  likeCount: number;
-  commentCount: number;
-  // ... 其他字段
-}
-```
-
-#### 4.2.2 创建ProcessPostUseCase
-```typescript
-// src/core/usecases/ProcessPostUseCase.ts
-class ProcessPostUseCase {
-  // 帖子增删改查
-  // 点赞/收藏逻辑
-  // 事件发布订阅
-}
-```
-
-#### 4.2.3 创建IPostRepository接口
-```typescript
-// src/data/repositories/interfaces/IPostRepository.ts
-interface IPostRepository {
-  getPosts(type: string, page: number, pageSize: number): Promise<Post[]>;
-  savePost(post: Post): Promise<void>;
-  updatePost(postId: string, updates: Partial<Post>): Promise<void>;
-  // ...
-}
-```
-
-#### 4.2.4 创建PostRepository实现
-```typescript
-// src/data/repositories/PostRepository.ts
-// 封装SQLite操作，实现IPostRepository接口
-```
-
-#### 4.2.5 创建useDifferentialPosts Hook
-```typescript
-// src/hooks/useDifferentialPosts.ts
-// 类似useDifferentialMessages，处理帖子列表差异更新
-```
-
-#### 4.2.6 改造postService
-- 移除对useUserStore的直接依赖
-- 仅保留API调用职责

-## 六、结论
-
-Messages模块是一个**架构完善**的模块，具备：
-1. 清晰的分层架构
-2. 独立的业务逻辑编排层（UseCase）
-3. 完整的数据持久化（SQLite）
-4. 高效的差异更新机制
-5. 实时事件推送能力
-
-Post模块当前存在以下问题：
-1. **违反分层原则**：Service直接操作Store
-2. **缺少UseCase层**：业务逻辑分散
-3. **无数据抽象**：缺少Repository接口
-4. **无差异更新**：每次全量更新导致性能问题
-5. **无本地持久化**：无法离线使用
-
-建议按照对齐建议逐步重构Post模块，使其架构与Messages模块对齐。

+//
+// 客户端职责（依据极光官方文档 https://docs.jiguang.cn/jpush/client/Android/android_3rd_guide）：
+//   1) 添加 cn.jiguang.sdk.plugin:vivo 依赖
+//   2) 注入 manifestPlaceholders: VIVO_APPKEY / VIVO_APPID（AAR 自带 vivo Receiver）
+//   3) 添加 Proguard 规则 (com.vivo.push.** + com.vivo.vms.** 保留)
+//
+// 注意事项：
+//   - 极光 JPUSH_CHANNEL 是「APK 分发渠道」统计字段，不是厂商通道开关，**不应覆盖**。
+//   - 客户端仅需要 VIVO_APPKEY / VIVO_APPID 两个占位符。
+//     VIVO_APP_SECRET 只在极光控制台「集成设置」页面填写，客户端不需要。
+//   - vivo AAR 已发布到 Maven Central，不需要额外 Maven 仓库。
+//   - vivo 平台限制：若应用未上架 vivo 商店，测试推送时需在 vivo 推送平台添加测试设备，
+//     且需通过 API 指定 push_mode=1（测试推送）下发。
+//
+// 实现说明：用 withDangerousMod 直接读写磁盘文件。
+// 原因：Expo SDK 56+ 的 withAppBuildGradle hook 链中，第二个以后的 plugin 写回
+// modResults.contents 会被静默忽略，导致多个 vendor plugin 只能写入第一个的修改。
