+# 数字分身 H5 生产接入与部署
+
+## 1. 接入方式
+
+生产会会在用户已登录后打开以下地址：
+
+```text
+https://digital.99hui.com/#/avatar/manage?token=<encodeURIComponent(会会 access token)>
+```
+
+测试环境示例：
+
+```text
+http://192.168.1.188:8099/#/avatar/manage?token=<encodeURIComponent(token)>
+```
+
+兼容参数位于域名查询串的形式，但生产统一使用上面的 hash 路由形式。必须对 token 调用 `encodeURIComponent`，不能拼接用户 ID 代替 token。
+
+免登录流程如下：
+
+1. H5 在页面渲染前读取 `token`，立即通过 `history.replaceState` 从地址栏和浏览器历史中移除。
+2. H5 调用 `POST /api/huihui/token/login`，不会把会会 token 当作数字分身接口 token 直接使用。
+3. 后端通过会会生产接口 `/im/box/netease` 换取 BOXIM 凭证，再调用 BOXIM `/user/self` 校验用户身份。
+4. 后端以返回的 `huihuiUserId` 绑定本地用户，保存会会凭证供 BOXIM 接管功能使用，并签发本系统 `app_token`。
+5. 浏览器只保存 `app_token` 和非敏感用户资料。会会原始 token 不返回浏览器存储。
+6. token 无效、过期或上游校验失败时清除旧会话并进入登录页，不会沿用上一位用户的缓存身份。
+
+## 2. 生产配置
+
+后端 `.env` 至少配置以下内容，密钥由部署平台注入，禁止提交 Git：
+
+```dotenv
+HUIHUI_DEV_MOCK=false
+HUIHUI_AUTH_BASE_URL=https://99hui.com/api/usercenter
+HUIHUI_PLATFORM_BASE_URL=https://open.99hui.com/api
+BOXIM_API_BASE_URL=https://im.99hui.com/api
+HUIHUI_APP_ID=<production-app-id>
+HUIHUI_ACCESS_ID=<production-access-id>
+HUIHUI_ACCESS_SECRET=<production-access-secret>
+HUIHUI_CLIENT_CODE=<production-client-code>
+BOXIM_TIMEOUT_SECONDS=20
+
+DATABASE_URL=sqlite:////data/avatar.db
+UPLOAD_DIR=/data/uploads
+CHAT_MODEL_CONFIG_URL=http://<huihuisquare-api>/api/ai-models/runtime/digital-avatar
+```
+
+如生产 AI 配置中心不可用，还应提供当前项目支持的 `OPENAI_API_KEY`、`OPENAI_BASE_URL`、`CHAT_MODEL` 等兜底配置。`/data` 必须挂载持久卷，数据库与知识库文件不可存放在容器临时层。
+
+## 3. 构建与发布
+
+首次发布前备份数据：
+
+```bash
+BACKUP_DIR="backups/$(date +%Y%m%d-%H%M%S)"
+mkdir -p "$BACKUP_DIR"
+cp /srv/digital-avatar/data/avatar.db "$BACKUP_DIR/"
+tar -C /srv/digital-avatar/data -czf "$BACKUP_DIR/uploads.tgz" uploads
+```
+
+在发布目录执行：
+
+```bash
+git fetch origin
+git checkout <已验收的提交SHA>
+cd digital-avatar-app
+docker compose build --pull avatar-backend avatar-frontend
+docker compose up -d avatar-backend avatar-frontend
+docker compose ps
+curl -fsS http://127.0.0.1:8099/api/health
+```
+
+生产编排应把示例中的测试端口改为内网暴露，由统一 HTTPS 网关接入。后端暂时使用 SQLite，必须保持单实例写入；若扩展为多后端实例，应先迁移到 PostgreSQL，并把延迟接管任务改为共享队列。
+
+## 4. 网关要求
+
+必须使用 HTTPS。同域部署时，H5 静态资源与 `/api/` 由同一域名提供，可避免跨域和 Cookie/来源策略问题。Nginx 关键配置示例：
+
+```nginx
+server_name digital.99hui.com;
+
+location / {
+    try_files $uri $uri/ /index.html;
+}
+
+location /api/ {
+    proxy_pass http://avatar-backend:8000;
+    proxy_http_version 1.1;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_buffering off;
+    proxy_read_timeout 300s;
+    client_max_body_size 20m;
+}
+```
+
+`proxy_buffering off` 用于数字分身 SSE 流式吐字，`client_max_body_size` 用于知识库文件上传。网关和应用日志必须关闭完整 URL 查询参数记录，任何异常日志都不得输出 token、Authorization 或平台密钥。建议同时设置严格的 `Referrer-Policy: no-referrer`。
+
+## 5. 发布验收
+
+1. 已登录会会用户通过带 token 链接打开后直接进入 `/avatar/manage`，不出现登录页或创建新账号页。
+2. 页面加载后地址栏中不再包含 `token`，刷新页面仍使用本地 `app_token` 正常访问。
+3. 后端用户绑定的是 BOXIM 返回的 `huihuiUserId`，不是 BOXIM 内部 `id`；原有数字分身、独立知识库和 Token 余额均存在。
+4. A、B 两个会会用户分别进入时只能看到各自的数字分身与知识库，不会继承上一用户缓存。
+5. 使用过期或伪造 token 时进入登录页并显示凭证失效，不得继续访问旧用户数据。
+6. 分身聊天 SSE 逐段输出正常，Markdown 正常渲染，知识库优先级和 Token 扣费正常。
+7. 开启 BOXIM 主动接管后保持在线，收到消息、三秒回复、已读回执和主人发言暂停均正常。
+8. 重建容器后数据库、头像、知识库文档仍存在，`/api/health` 返回成功。
+9. `https://digital.99hui.com/api/health` 可访问，证书域名和有效期正确，HTTP 自动跳转 HTTPS。
+
+## 6. 回滚
+
+保留上一版前后端镜像标签和发布前数据库/上传文件备份。代码回滚优先切回上一镜像；只有新版本执行了不可逆数据变更时才恢复数据库。恢复前先停止后端写入，恢复后对比用户数、分身数、知识库文档数并完成一次免登录和聊天验收。

+# 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
+```
+
+---
+
+## 4. 核心流程
+
+### 4.1 消息监听流程

+
+## 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
