fix: prevent crash when switching between agent and assistant (#12252)

Remove the confusing V2 naming from message thunk functions to avoid conflicts with the upcoming real V2 data refactoring.

  Changes:
  - Inline V2 function implementations directly into messageThunk.ts
  - Replace V2 function calls with direct dbService calls
  - Remove messageThunk.v2.ts file
  - Remove misleading "V2 DATA&UI REFACTORING" header comments

  The V2 suffix was originally added for agent session support, not for a data layer refactoring. This cleanup clears the naming space for the actual V2 refactoring work.

 ### 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.

+# Fuzzy Search for File List
+
+This document describes the fuzzy search implementation for file listing in Cherry Studio.
+
+## Overview
+
+The fuzzy search feature allows users to find files by typing partial or approximate file names/paths. It uses a two-tier file filtering strategy (ripgrep glob pre-filtering with greedy substring fallback) combined with subsequence-based scoring for optimal performance and flexibility.
+
+## Features
+
+- **Ripgrep Glob Pre-filtering**: Primary filtering using glob patterns for fast native-level filtering
+- **Greedy Substring Matching**: Fallback file filtering strategy when ripgrep glob pre-filtering returns no results
+- **Subsequence-based Segment Scoring**: During scoring, path segments gain additional weight when query characters appear in order
+- **Relevance Scoring**: Results are sorted by a relevance score derived from multiple factors
+
+## Matching Strategies
+
+### 1. Ripgrep Glob Pre-filtering (Primary)
+
+The query is converted to a glob pattern for ripgrep to do initial filtering:
+
+```
+Query: "updater"
+Glob:  "*u*p*d*a*t*e*r*"
+```
+
+This leverages ripgrep's native performance for the initial file filtering.
+
+### 2. Greedy Substring Matching (Fallback)
+
+When the glob pre-filter returns no results, the system falls back to greedy substring matching. This allows more flexible matching:
+
+```
+Query: "updatercontroller"
+File:  "packages/update/src/node/updateController.ts"
+
+Matching process:
+1. Find "update" (longest match from start)
+2. Remaining "rcontroller" → find "r" then "controller"
+3. All parts matched → Success
+```
+
+## Scoring Algorithm
+
+Results are ranked by a relevance score based on named constants defined in `FileStorage.ts`:
+
+| Constant | Value | Description |
+|----------|-------|-------------|
+| `SCORE_FILENAME_STARTS` | 100 | Filename starts with query (highest priority) |
+| `SCORE_FILENAME_CONTAINS` | 80 | Filename contains exact query substring |
+| `SCORE_SEGMENT_MATCH` | 60 | Per path segment that matches query |
+| `SCORE_WORD_BOUNDARY` | 20 | Query matches start of a word |
+| `SCORE_CONSECUTIVE_CHAR` | 15 | Per consecutive character match |
+| `PATH_LENGTH_PENALTY_FACTOR` | 4 | Logarithmic penalty for longer paths |
+
+### Scoring Strategy
+
+The scoring prioritizes:
+1. **Filename matches** (highest): Files where the query appears in the filename are most relevant
+2. **Path segment matches**: Multiple matching segments indicate stronger relevance
+3. **Word boundaries**: Matching at word starts (e.g., "upd" matching "update") is preferred
+4. **Consecutive matches**: Longer consecutive character sequences score higher
+5. **Path length**: Shorter paths are preferred (logarithmic penalty prevents long paths from dominating)
+
+### Example Scoring
+
+For query `updater`:
+
+| File | Score Factors |
+|------|---------------|
+| `RCUpdater.js` | Short path + filename contains "updater" |
+| `updateController.ts` | Multiple segment matches |
+| `UpdaterHelper.plist` | Long path penalty |
+
+## Configuration
+
+### DirectoryListOptions
+
+```typescript
+interface DirectoryListOptions {
+  recursive?: boolean      // Default: true
+  maxDepth?: number        // Default: 10
+  includeHidden?: boolean  // Default: false
+  includeFiles?: boolean   // Default: true
+  includeDirectories?: boolean // Default: true
+  maxEntries?: number      // Default: 20
+  searchPattern?: string   // Default: '.'
+  fuzzy?: boolean          // Default: true
+}
+```
+
+## Usage
+
+```typescript
+// Basic fuzzy search
+const files = await window.api.file.listDirectory(dirPath, {
+  searchPattern: 'updater',
+  fuzzy: true,
+  maxEntries: 20
+})
+
+// Disable fuzzy search (exact glob matching)
+const files = await window.api.file.listDirectory(dirPath, {
+  searchPattern: 'update',
+  fuzzy: false
+})
+```
+
+## Performance Considerations
+
+1. **Ripgrep Pre-filtering**: Most queries are handled by ripgrep's native glob matching, which is extremely fast
+2. **Fallback Only When Needed**: Greedy substring matching (which loads all files) only runs when glob matching returns empty results
+3. **Result Limiting**: Only top 20 results are returned by default
+4. **Excluded Directories**: Common large directories are automatically excluded:
+   - `node_modules`
+   - `.git`
+   - `dist`, `build`
+   - `.next`, `.nuxt`
+   - `coverage`, `.cache`
+
+## Implementation Details
+
+The implementation is located in `src/main/services/FileStorage.ts`:
+
+- `queryToGlobPattern()`: Converts query to ripgrep glob pattern
+- `isFuzzyMatch()`: Subsequence matching algorithm
+- `isGreedySubstringMatch()`: Greedy substring matching fallback
+- `getFuzzyMatchScore()`: Calculates relevance score
+- `listDirectoryWithRipgrep()`: Main search orchestration

+# 文件列表模糊搜索
+
+本文档描述了 Cherry Studio 中文件列表的模糊搜索实现。
+
+## 概述
+
+模糊搜索功能允许用户通过输入部分或近似的文件名/路径来查找文件。它使用两层文件过滤策略（ripgrep glob 预过滤 + 贪婪子串匹配回退），结合基于子序列的评分，以获得最佳性能和灵活性。
+
+## 功能特性
+
+- **Ripgrep Glob 预过滤**：使用 glob 模式进行快速原生级过滤的主要过滤策略
+- **贪婪子串匹配**：当 ripgrep glob 预过滤无结果时的回退文件过滤策略
+- **基于子序列的段评分**：评分时，当查询字符按顺序出现时，路径段获得额外权重
+- **相关性评分**：结果按多因素相关性分数排序
+
+## 匹配策略
+
+### 1. Ripgrep Glob 预过滤（主要）
+
+查询被转换为 glob 模式供 ripgrep 进行初始过滤：
+
+```
+查询: "updater"
+Glob: "*u*p*d*a*t*e*r*"
+```
+
+这利用了 ripgrep 的原生性能进行初始文件过滤。
+
+### 2. 贪婪子串匹配（回退）
+
+当 glob 预过滤无结果时，系统回退到贪婪子串匹配。这允许更灵活的匹配：
+
+```
+查询: "updatercontroller"
+文件: "packages/update/src/node/updateController.ts"
+
+匹配过程:
+1. 找到 "update"（从开头的最长匹配）
+2. 剩余 "rcontroller" → 找到 "r" 然后 "controller"
+3. 所有部分都匹配 → 成功
+```
+
+## 评分算法
+
+结果根据 `FileStorage.ts` 中定义的命名常量进行相关性分数排名：
+
+| 常量 | 值 | 描述 |
+|------|-----|------|
+| `SCORE_FILENAME_STARTS` | 100 | 文件名以查询开头（最高优先级）|
+| `SCORE_FILENAME_CONTAINS` | 80 | 文件名包含精确查询子串 |
+| `SCORE_SEGMENT_MATCH` | 60 | 每个匹配查询的路径段 |
+| `SCORE_WORD_BOUNDARY` | 20 | 查询匹配单词开头 |
+| `SCORE_CONSECUTIVE_CHAR` | 15 | 每个连续字符匹配 |
+| `PATH_LENGTH_PENALTY_FACTOR` | 4 | 较长路径的对数惩罚 |
+
+### 评分策略
+
+评分优先级：
+1. **文件名匹配**（最高）：查询出现在文件名中的文件最相关
+2. **路径段匹配**：多个匹配段表示更强的相关性
+3. **词边界**：在单词开头匹配（如 "upd" 匹配 "update"）更优先
+4. **连续匹配**：更长的连续字符序列得分更高
+5. **路径长度**：较短路径更优先（对数惩罚防止长路径主导评分）
+
+### 评分示例
+
+对于查询 `updater`：
+
+| 文件 | 评分因素 |
+|------|----------|
+| `RCUpdater.js` | 短路径 + 文件名包含 "updater" |
+| `updateController.ts` | 多个路径段匹配 |
+| `UpdaterHelper.plist` | 长路径惩罚 |
+
+## 配置
+
+### DirectoryListOptions
+
+```typescript
+interface DirectoryListOptions {
+  recursive?: boolean      // 默认: true
+  maxDepth?: number        // 默认: 10
+  includeHidden?: boolean  // 默认: false
+  includeFiles?: boolean   // 默认: true
+  includeDirectories?: boolean // 默认: true
+  maxEntries?: number      // 默认: 20
+  searchPattern?: string   // 默认: '.'
+  fuzzy?: boolean          // 默认: true
+}
+```
+
+## 使用方法
+
+```typescript
+// 基本模糊搜索
+const files = await window.api.file.listDirectory(dirPath, {
+  searchPattern: 'updater',
+  fuzzy: true,
+  maxEntries: 20
+})
+
+// 禁用模糊搜索（精确 glob 匹配）
+const files = await window.api.file.listDirectory(dirPath, {
+  searchPattern: 'update',
+  fuzzy: false
+})
+```
+
+## 性能考虑
+
+1. **Ripgrep 预过滤**：大多数查询由 ripgrep 的原生 glob 匹配处理，速度极快
+2. **仅在需要时回退**：贪婪子串匹配（加载所有文件）仅在 glob 匹配返回空结果时运行
+3. **结果限制**：默认只返回前 20 个结果
+4. **排除目录**：自动排除常见的大型目录：
+   - `node_modules`
+   - `.git`
+   - `dist`、`build`
+   - `.next`、`.nuxt`
+   - `coverage`、`.cache`
+
+## 实现细节
+
+实现位于 `src/main/services/FileStorage.ts`：
+
+- `queryToGlobPattern()`：将查询转换为 ripgrep glob 模式
+- `isFuzzyMatch()`：子序列匹配算法
+- `isGreedySubstringMatch()`：贪婪子串匹配回退
+- `getFuzzyMatchScore()`：计算相关性分数
+- `listDirectoryWithRipgrep()`：主搜索协调

+
+### 1.1 架构角色
+
+| 角色                 | 平台            | 职责                         |
+| -------------------- | --------------- | ---------------------------- |
+| **Client（客户端）** | Electron 桌面端 | 扫描服务、发起连接、发送文件 |
+| **Server（服务端）** | Expo 移动端     | 发布服务、接受连接、接收文件 |
+
+### 1.2 协议栈（v1）
+
+```
+┌─────────────────────────────────────┐
+│     应用层（文件传输）                │
+├─────────────────────────────────────┤
+│     消息层（控制: JSON \n）           │
+│             （数据: 二进制帧）        │
+├─────────────────────────────────────┤
+│     传输层（TCP）                    │
+├─────────────────────────────────────┤
+│     发现层（Bonjour/mDNS）           │
+└─────────────────────────────────────┘
+```
+
+### 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。

+
+### 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）

+
+### 7.3 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
+  }
+}
+```
