 ### Electron Structure
 - **Main Process** (`src/main/`): Node.js backend with services (MCP, Knowledge, Storage, etc.)
 - **Renderer Process** (`src/renderer/`): React UI with Redux state management
 - **Preload Scripts** (`src/preload/`): Secure IPC bridge
 ### Key Components
 - **AI Core** (`src/renderer/src/aiCore/`): Middleware pipeline for multiple AI providers.
 - **Services** (`src/main/services/`): MCPService, KnowledgeService, WindowService, etc.
 - **Build System**: Electron-Vite with experimental rolldown-vite, yarn workspaces.
 - **State Management**: Redux Toolkit (`src/renderer/src/store/`) for predictable state.

 ### 1.3 通信流程概览
 ```
 1. 服务发现 → 移动端发布 mDNS 服务，桌面端扫描发现
 2. TCP 握手 → 建立连接，交换设备信息（`version=1`）
 3. 文件传输 → 控制消息使用 JSON，`file_chunk` 使用二进制帧分块传输
 4. 连接保活 → ping/pong 心跳
 ```
 ---
 ## 2. 服务发现（Bonjour/mDNS）
 ### 2.1 服务类型
 | 属性         | 值                   |
 | ------------ | -------------------- |
 | 服务类型     | `cherrystudio`       |
 | 协议         | `tcp`                |
 | 完整服务标识 | `_cherrystudio._tcp` |
 ### 2.2 服务发布（移动端）
 移动端需要通过 mDNS/Bonjour 发布服务：
 ```typescript
 // 服务发布参数
 {
  name: "Cherry Studio Mobile",    // 设备名称
  type: "cherrystudio",            // 服务类型
  protocol: "tcp",                 // 协议
  port: 53317,                     // TCP 监听端口
  txt: {                           // TXT 记录（可选）
    version: "1",
    platform: "ios"                // 或 "android"
  }
 }
 ```
 ### 2.3 服务发现（桌面端）
 桌面端扫描并解析服务信息：
 ```typescript
 // 发现的服务信息结构
 type LocalTransferPeer = {
  id: string; // 唯一标识符
  name: string; // 设备名称
  host?: string; // 主机名
  fqdn?: string; // 完全限定域名
  port?: number; // TCP 端口
  type?: string; // 服务类型
  protocol?: "tcp" | "udp"; // 协议
  addresses: string[]; // IP 地址列表
  txt?: Record<string, string>; // TXT 记录
  updatedAt: number; // 发现时间戳
 };
 ```
 ### 2.4 IP 地址选择策略
 当服务有多个 IP 地址时，优先选择 IPv4：
 ```typescript
 // 优先选择 IPv4 地址
 const preferredAddress = addresses.find((addr) => isIPv4(addr)) || addresses[0];
 ```
 ---
 ## 3. TCP 连接与握手
 ### 3.1 连接建立
 1. 客户端使用发现的 `host:port` 建立 TCP 连接
 2. 连接成功后立即发送握手消息
 3. 等待服务端响应握手确认
 ### 3.2 握手消息（协议版本 v1）
 #### Client → Server: `handshake`
 ```typescript
 type LanTransferHandshakeMessage = {
  type: "handshake";
  deviceName: string; // 设备名称
  version: string; // 协议版本，当前为 "1"
  platform?: string; // 平台：'darwin' | 'win32' | 'linux'
  appVersion?: string; // 应用版本
 };
 ```
 **示例：**
 ```json
 {
  "type": "handshake",
  "deviceName": "Cherry Studio 1.7.2",
  "version": "1",
  "platform": "darwin",
  "appVersion": "1.7.2"
 }
 ```
 ### 4. 消息格式规范（混合协议）
 v1 使用"控制 JSON + 二进制数据帧"的混合协议（流式传输模式，无 per-chunk ACK）：
 - **控制消息**（握手、心跳、file_start/ack、file_end、file_complete）：UTF-8 JSON，`\n` 分隔
 - **数据消息**（`file_chunk`）：二进制帧，使用 Magic + 总长度做分帧，不经 Base64
 ### 4.1 控制消息编码（JSON + `\n`）
 | 属性       | 规范         |
 | ---------- | ------------ |
 | 编码格式   | UTF-8        |
 | 序列化格式 | JSON         |
 | 消息分隔符 | `\n`（0x0A） |
 ```typescript
 function sendControlMessage(socket: Socket, message: object): void {
  socket.write(`${JSON.stringify(message)}\n`);
 }
 ```
 ### 4.2 `file_chunk` 二进制帧格式
 为解决 TCP 分包/粘包并消除 Base64 开销，`file_chunk` 采用带总长度的二进制帧：
 ```
 ┌──────────┬──────────┬────────┬───────────────┬──────────────┬────────────┬───────────┐
 │ Magic    │ TotalLen │ Type   │ TransferId Len│ TransferId   │ ChunkIdx   │ Data      │
 │ 0x43 0x53│ (4B BE)  │ 0x01   │ (2B BE)       │ (UTF-8)      │ (4B BE)    │ (raw)     │
 └──────────┴──────────┴────────┴───────────────┴──────────────┴────────────┴───────────┘
 ```
 | 字段           | 大小 | 说明                                        |
 | -------------- | ---- | ------------------------------------------- |
 | Magic          | 2B   | 常量 `0x43 0x53` ("CS"), 用于区分 JSON 消息 |
 | TotalLen       | 4B   | Big-endian，帧总长度（不含 Magic/TotalLen） |
 | Type           | 1B   | `0x01` 代表 `file_chunk`                    |
 | TransferId Len | 2B   | Big-endian，transferId 字符串长度           |
 | TransferId     | nB   | UTF-8 transferId（长度由上一字段给出）      |
 | ChunkIdx       | 4B   | Big-endian，块索引，从 0 开始               |
 | Data           | mB   | 原始文件二进制数据（未编码）                |
 > 计算帧总长度：`TotalLen = 1 + 2 + transferIdLen + 4 + dataLen`（即 Type~Data 的长度和）。
 ### 4.3 消息解析策略
 1. 读取 socket 数据到缓冲区；
 2. 若前两字节为 `0x43 0x53` → 按二进制帧解析：
   - 至少需要 6 字节头（Magic + TotalLen），不足则等待更多数据
   - 读取 `TotalLen` 判断帧整体长度，缓冲区不足则继续等待
   - 解析 Type/TransferId/ChunkIdx/Data，并传入文件接收逻辑
 3. 否则若首字节为 `{` → 按 JSON + `\n` 解析控制消息
 4. 其它数据丢弃 1 字节并继续循环，避免阻塞。
 ### 4.4 消息类型汇总（v1）
 | 类型             | 方向            | 编码     | 用途                    |
 | ---------------- | --------------- | -------- | ----------------------- |
 | `handshake`      | Client → Server | JSON+\n  | 握手请求（version=1）   |
 | `handshake_ack`  | Server → Client | JSON+\n  | 握手响应                |
 | `ping`           | Client → Server | JSON+\n  | 心跳请求                |

 ### 5.2 消息定义
 #### 5.2.1 `file_start` - 开始传输
 **方向：** Client → Server
 ```typescript
 type LanTransferFileStartMessage = {
  type: "file_start";
  transferId: string; // UUID，唯一传输标识
  fileName: string; // 文件名（含扩展名）
  fileSize: number; // 文件总字节数
  mimeType: string; // MIME 类型
  checksum: string; // 整个文件的 SHA-256 哈希（hex）
  totalChunks: number; // 总数据块数
  chunkSize: number; // 每块大小（字节）
 };
 ```
 **示例：**
 ```json
 {
  "type": "file_start",
  "transferId": "550e8400-e29b-41d4-a716-446655440000",
  "fileName": "backup.zip",
  "fileSize": 524288000,
  "mimeType": "application/zip",
  "checksum": "a1b2c3d4e5f6789012345678901234567890abcdef1234567890abcdef123456",
  "totalChunks": 8192,
  "chunkSize": 65536
 }
 ```
 #### 5.2.2 `file_start_ack` - 传输确认
 **方向：** Server → Client
 ```typescript
 type LanTransferFileStartAckMessage = {
  type: "file_start_ack";
  transferId: string; // 对应的传输 ID
  accepted: boolean; // 是否接受传输
  message?: string; // 拒绝原因
 };
 ```
 **接受示例：**
 ```json
 {
  "type": "file_start_ack",
  "transferId": "550e8400-e29b-41d4-a716-446655440000",
  "accepted": true
 }
 ```
 **拒绝示例：**
 ```json
 {
  "type": "file_start_ack",
  "transferId": "550e8400-e29b-41d4-a716-446655440000",
  "accepted": false,
  "message": "Insufficient storage space"
 }
 ```
 #### 5.2.3 `file_chunk` - 数据块
 **方向：** Client → Server（**二进制帧**，见 4.2）
 - 不再使用 JSON/`\n`，也不再使用 Base64
 - 帧结构：`Magic` + `TotalLen` + `Type` + `TransferId` + `ChunkIdx` + `Data`
 - `Type` 固定 `0x01`，`Data` 为原始文件二进制数据
 - 传输完整性依赖 `file_start.checksum`（全文件 SHA-256）；分块校验和可选，不在帧中发送
 #### 5.2.4 `file_chunk_ack` - 数据块确认（v1 流式不使用）
 v1 采用流式传输，不发送 per-chunk ACK。本节类型仅保留作为向后兼容参考，实际不会发送。
 #### 5.2.5 `file_end` - 传输结束
 **方向：** Client → Server
 ```typescript
 type LanTransferFileEndMessage = {
  type: "file_end";
  transferId: string; // 传输 ID
 };
 ```
 **示例：**
 ```json
 {
  "type": "file_end",
  "transferId": "550e8400-e29b-41d4-a716-446655440000"
 }
 ```
 #### 5.2.6 `file_complete` - 传输完成
 **方向：** Server → Client
 ```typescript
 type LanTransferFileCompleteMessage = {
  type: "file_complete";
  transferId: string; // 传输 ID
  success: boolean; // 是否成功
  filePath?: string; // 保存路径（成功时）
  error?: string; // 错误信息（失败时）
 };
 ```
 **成功示例：**
 ```json
 {
  "type": "file_complete",
  "transferId": "550e8400-e29b-41d4-a716-446655440000",
  "success": true,
  "filePath": "/storage/emulated/0/Documents/backup.zip"
 }
 ```
 **失败示例：**
 ```json
 {
  "type": "file_complete",
  "transferId": "550e8400-e29b-41d4-a716-446655440000",
  "success": false,
  "error": "File checksum verification failed"
 }
 ```
 ### 5.3 校验和算法
 #### 整个文件校验和（保持不变）
 ```typescript
 async function calculateFileChecksum(filePath: string): Promise<string> {
  const hash = crypto.createHash("sha256");
  const stream = fs.createReadStream(filePath);
  for await (const chunk of stream) {
    hash.update(chunk);
  }
  return hash.digest("hex");
 }
 ```
 #### 数据块校验和
 v1 默认 **不传输分块校验和**，依赖最终文件 checksum。若需要，可在应用层自定义（非协议字段）。
 ### 5.4 校验流程
 **发送端（Client）：**
 1. 发送前计算整个文件的 SHA-256 → `file_start.checksum`
 2. 分块直接发送原始二进制（无 Base64）
 **接收端（Server）：**
 1. 收到 `file_chunk` 后直接使用二进制数据
 2. 边收边落盘并增量计算 SHA-256（推荐）
 3. 所有块接收完成后，计算/完成增量哈希，得到最终 SHA-256
 4. 与 `file_start.checksum` 比对，结果写入 `file_complete`
 ### 5.5 数据块大小计算
 ```typescript
 const CHUNK_SIZE = 512 * 1024; // 512KB
 const totalChunks = Math.ceil(fileSize / CHUNK_SIZE);
 // 最后一个块可能小于 CHUNK_SIZE
 const lastChunkSize = fileSize % CHUNK_SIZE || CHUNK_SIZE;
 ```
 ---
 ## 6. 心跳与连接保活
 ### 6.1 心跳消息
 #### `ping`
 **方向：** Client → Server
 ```typescript
 type LanTransferPingMessage = {
  type: "ping";
  payload?: string; // 可选载荷
 };
 ```
 ```json
 {
  "type": "ping",
  "payload": "heartbeat"
 }
 ```
 #### `pong`
 **方向：** Server → Client
 ```typescript
 type LanTransferPongMessage = {
  type: "pong";
  received: boolean; // 确认收到
  payload?: string; // 回传 ping 的载荷
 };
 ```
 ```json
 {
  "type": "pong",
  "received": true,
  "payload": "heartbeat"
 }
 ```
 ### 6.2 心跳策略
 - 握手成功后立即发送一次 `ping` 验证连接
 - 可选：定期发送心跳保持连接活跃
 - `pong` 应返回 `ping` 中的 `payload`（可选）

 ## 7. 错误处理
 ### 7.1 超时配置
 | 操作       | 超时时间 | 说明                  |
 | ---------- | -------- | --------------------- |
 | TCP 连接   | 10 秒    | 连接建立超时          |
 | 握手等待   | 10 秒    | 等待 `handshake_ack`  |
 | 传输完成   | 60 秒    | 等待 `file_complete`  |
 ### 7.2 错误场景处理
 | 场景            | Client 处理        | Server 处理            |
 | --------------- | ------------------ | ---------------------- |
 | TCP 连接失败    | 通知 UI，允许重试  | -                      |
 | 握手超时        | 断开连接，通知 UI  | 关闭 socket            |
 | 握手被拒绝      | 显示拒绝原因       | -                      |
 | 数据块处理失败  | 中止传输，清理状态 | 清理临时文件           |

 | 存储空间不足    | -                  | 发送 `accepted: false` |
 ### 7.3 资源清理
 **Client 端：**
 ```typescript
 function cleanup(): void {
  // 1. 销毁文件读取流
  if (readStream) {
    readStream.destroy();
  }
  // 2. 清理传输状态
  activeTransfer = undefined;
  // 3. 关闭 socket（如需要）
  socket?.destroy();
 }
 ```
 **Server 端：**
 ```typescript
 function cleanup(): void {
  // 1. 关闭文件写入流
  if (writeStream) {
    writeStream.end();
  }
  // 2. 删除未完成的临时文件
  if (tempFilePath) {
    fs.unlinkSync(tempFilePath);
  }
  // 3. 清理传输状态
  activeTransfer = undefined;
 }
 ```

 ## 10. 移动端实现指南（v1 要点）
 ### 10.1 必须实现的功能
 1. **mDNS 服务发布**
   - 发布 `_cherrystudio._tcp` 服务
   - 提供 TCP 端口号 `53317`
   - 可选：TXT 记录（版本、平台信息）
 2. **TCP 服务端**
   - 监听指定端口
   - 支持单连接或多连接
 3. **消息解析**
   - 控制消息：UTF-8 + `\n` JSON
   - 数据消息：二进制帧（Magic+TotalLen 分帧）
 4. **握手处理**
   - 验证 `handshake` 消息
   - 发送 `handshake_ack` 响应
   - 响应 `ping` 消息
 5. **文件接收（流式模式）**
   - 解析 `file_start`，准备接收
   - 接收 `file_chunk` 二进制帧，直接写入文件/缓冲并增量哈希
   - v1 不发送 per-chunk ACK（流式传输）
   - 处理 `file_end`，完成增量哈希并校验 checksum
   - 发送 `file_complete` 结果
 ### 10.2 推荐的库
 **React Native / Expo：**
 - mDNS: `react-native-zeroconf` 或 `@homielab/react-native-bonjour`
 - TCP: `react-native-tcp-socket`
 - Crypto: `expo-crypto` 或 `react-native-quick-crypto`
 ### 10.3 接收端伪代码
 ```typescript
 class FileReceiver {
  private transfer?: {
    id: string;
    fileName: string;
    fileSize: number;
    checksum: string;
    totalChunks: number;
    receivedChunks: number;
    tempPath: string;
    // v1: 边收边写文件，避免大文件 OOM
    // stream: FileSystem writable stream (平台相关封装)
  };
  handleMessage(message: any) {
    switch (message.type) {
      case "handshake":
        this.handleHandshake(message);
        break;
      case "ping":
        this.sendPong(message);
        break;
      case "file_start":
        this.handleFileStart(message);
        break;
      // v1: file_chunk 为二进制帧，不再走 JSON 分支
      case "file_end":
        this.handleFileEnd(message);
        break;
    }
  }
  handleFileStart(msg: LanTransferFileStartMessage) {
    // 1. 检查存储空间
    // 2. 创建临时文件
    // 3. 初始化传输状态
    // 4. 发送 file_start_ack
  }
  // v1: 二进制帧处理在 socket data 流中解析，随后调用 handleBinaryFileChunk
  handleBinaryFileChunk(transferId: string, chunkIndex: number, data: Buffer) {
    // 直接使用二进制数据，按 chunkSize/lastChunk 计算长度
    // 写入文件流并更新增量 SHA-256
    this.transfer.receivedChunks++;
    // v1: 流式传输，不发送 per-chunk ACK
  }
  handleFileEnd(msg: LanTransferFileEndMessage) {
    // 1. 合并所有数据块
    // 2. 验证完整文件 checksum
    // 3. 写入最终位置
    // 4. 发送 file_complete
  }
 }
 ```

 ## 附录 A：TypeScript 类型定义
 完整的类型定义位于 `packages/shared/config/types.ts`：
 ```typescript
 // 握手消息
 export interface LanTransferHandshakeMessage {
  type: "handshake";
  deviceName: string;
  version: string;
  platform?: string;
  appVersion?: string;
 }
 export interface LanTransferHandshakeAckMessage {
  type: "handshake_ack";
  accepted: boolean;
  message?: string;
 }
 // 心跳消息
 export interface LanTransferPingMessage {
  type: "ping";
  payload?: string;
 }
 export interface LanTransferPongMessage {
  type: "pong";
  received: boolean;
  payload?: string;
 }
 // 文件传输消息 (Client -> Server)
 export interface LanTransferFileStartMessage {
  type: "file_start";
  transferId: string;
  fileName: string;
  fileSize: number;
  mimeType: string;
  checksum: string;
  totalChunks: number;
  chunkSize: number;
 }
 export interface LanTransferFileChunkMessage {
  type: "file_chunk";
  transferId: string;
  chunkIndex: number;
  data: string; // Base64 encoded (v1: 二进制帧模式下不使用)
 }
 export interface LanTransferFileEndMessage {
  type: "file_end";
  transferId: string;
 }
 // 文件传输响应消息 (Server -> Client)
 export interface LanTransferFileStartAckMessage {
  type: "file_start_ack";
  transferId: string;
  accepted: boolean;
  message?: string;
 }
 // v1 流式不发送 per-chunk ACK，以下类型仅用于向后兼容参考
 export interface LanTransferFileChunkAckMessage {
  type: "file_chunk_ack";
  transferId: string;
  chunkIndex: number;
  received: boolean;
  error?: string;
 }
 export interface LanTransferFileCompleteMessage {
  type: "file_complete";
  transferId: string;
  success: boolean;
  filePath?: string;
  error?: string;
 }
 // 常量
 export const LAN_TRANSFER_TCP_PORT = 53317;
 export const LAN_TRANSFER_CHUNK_SIZE = 512 * 1024;
 export const LAN_TRANSFER_CHUNK_TIMEOUT_MS = 30_000;
 ```
