+# 数字分身接管聊天功能 — 设计文档
+
+## 1. 概述
+
+### 1.1 背景
+当前数字分身应用中，分身只能与主人一对一聊天。用户希望分身能在主人授权下，接管主人在会会平台上的聊天（单聊和群聊），替主人与他人对话。
+
+### 1.2 目标
+- 主人可在授权管理页面开启"分身接管聊天"功能
+- 支持两种接管模式：立即接管、延迟接管（N 秒后）
+- 分身回复优先使用知识库（QA 问答对 + 文档向量搜索）
+- 支持单聊和群聊两种场景
+- 以主人身份发送回复，对方无感知
+
+### 1.3 技术基础
+- 会会平台使用网易云信作为 IM 底层
+- 已有接口：`/api/im/netease`（获取云信凭证）、`/api/v2message/push/record/*`（消息推送）
+- 已有分身聊天接口：`POST /api/avatar/{id}/chat`
+
+---
+
+## 2. 架构设计
+
+### 2.1 整体架构
+
+```

+
+### 2.2 模块划分
+
+| 模块 | 位置 | 职责 |
+|------|------|------|
+| 接管配置 | 授权管理页面 + authorizations 表 | 存储接管开关、模式、延迟秒数 |
+| 消息监听器 | 后端定时任务 | 轮询网易云信消息，发现新消息 |
+| 接管决策器 | 后端服务 | 判断是否接管、立即还是延迟 |
+| 回复执行器 | 后端服务 | 调用分身聊天接口生成回复，以主人身份发送 |
+| 延迟队列 | Redis | 存储待处理消息，实现延迟接管 |
+
+---
+
+## 3. 数据模型
+
+### 3.1 扩展 Authorization 表
+
+在现有 `authorizations` 表基础上新增字段：
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| `takeover_enabled` | BOOLEAN | 是否开启分身接管聊天 |
+| `takeover_mode` | VARCHAR | 接管模式：`immediate`（立即）/ `delayed`（延迟） |
+| `takeover_delay_seconds` | INTEGER | 延迟秒数（仅 delayed 模式有效），默认 30 |
+
+**权限关联**：
+- `permissions` 数组中包含 `"takeover"` 时，表示该授权允许分身接管
+- `target_type = "user"` 且 `permissions` 含 `"takeover"` → 单聊接管
+- `target_type = "organization"` 或群聊相关 → 群聊接管
+
+### 3.2 Redis 数据结构
+
+```
+# 延迟消息队列
+takeover:delayed:{owner_accid}:{message_id} = {
+  "avatar_id": "...",
+  "from_accid": "...",
+  "content": "...",
+  "chat_type": "p2p|group",
+  "chat_id": "...",
+  "timestamp": 1234567890
+}
+TTL = takeover_delay_seconds + 10
+```
+
+---

+

+
+## 5. API 设计
+
+### 5.1 授权管理增强
+
+**PUT /api/avatar/{avatar_id}/authorizations/takeover**
+
+请求体：
+```json
+{
+  "authorization_id": "授权记录ID",
+  "takeover_enabled": true,
+  "takeover_mode": "delayed",
+  "takeover_delay_seconds": 30
+}
+```
+
+### 5.2 消息监听（内部接口）
+
+**POST /api/internal/takeover/process**
+
+由定时任务调用，无需认证。
+
+请求体：
+```json
+{
+  "owner_accid": "主人网易云信账号",
+  "messages": [
+    {
+      "msg_id": "消息ID",
+      "from_accid": "发送者账号",
+      "content": "消息内容",
+      "chat_type": "p2p",
+      "chat_id": "会话ID",
+      "timestamp": 1234567890
+    }
+  ]
+}
+```
+
+### 5.3 网易云信消息发送
+
+复用现有网易云信 API 封装，新增单聊消息发送方法：
+
+**POST /im/netease/message/send/p2p**
+
+请求体：
+```json
+{
+  "from_accid": "主人账号",
+  "to_accid": "对方账号",
+  "content": "回复内容",
+  "msg_type": "text"
+}
+```
+
+---
+
+## 6. 错误处理
+
+| 场景 | 处理方式 |
+|------|---------|
+| 分身聊天接口调用失败 | 记录日志，不回复，下次继续监听 |
+| 网易云信发送失败 | 重试 3 次，失败后记录日志 |
+| 主人有多个分身 | 取第一个 active 状态的分身 |
+| 知识库无匹配内容 | 使用 Qwen 兜底生成回复 |
+| Redis 连接失败 | 降级为立即接管模式 |
+
+---
+
+## 7. 配置项
+
+在 `SystemConfig` 表中新增配置：
+
+| 配置 key | 说明 | 默认值 |
+|---------|------|-------|
+| `takeover_poll_interval` | 消息轮询间隔（秒） | 10 |
+| `takeover_default_delay` | 默认延迟秒数 | 30 |
+| `takeover_retry_times` | 发送重试次数 | 3 |
+
+---
+
+## 8. 测试要点
+
+1. **功能测试**
+   - 立即接管：收到消息后立即由分身回复
+   - 延迟接管：主人 N 秒内回复则不分身接管，超时则分身回复
+   - 知识库优先：QA 问答对精确匹配优先返回
+
+2. **边界测试**
+   - 主人有多个分身时的选择逻辑
+   - 知识库为空时的 Qwen 兜底
+   - 网易云信 API 异常时的降级
+
+3. **性能测试**
+   - 轮询频率对服务器负载的影响
+   - Redis 延迟队列的内存占用
+
+---
+
+## 9. 后续扩展
+
+- Webhook 回调替代轮询（需要会会平台支持）
+- 多分身协同接管
+- 接管历史记录和统计
+- 接管效果评估和优化
