+# 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

+```
+
+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。
+
+`EMBEDDING_API_URL` 同时支持 OpenAI 兼容基础地址（如上面的 `/v1`）和完整的 `/v1/embeddings` 地址，后端会统一请求 `/embeddings`。发布后必须在后端容器内执行一次最小向量探针，确认返回向量数量和维度，而不能只检查 `/api/health`。
+
+积分充值使用会会支付体系的 `payment-v3/payment/pay`，渠道值为 `WECHAT` / `ALIPAY`，端内支付场景为 `APP`，微信内 H5 使用 `JSAPI`。`HUIHUI_PAYMENT_CALLBACK_SECRET` 只用于为每笔订单生成 HMAC 回调签名，不会发送到前端或直接出现在回调地址中。支付回调确认状态成功且金额与套餐价格完全一致后才增加积分，重复回调不会重复到账。
+
+## 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
+docker compose exec avatar-backend python -c 'import embeddings; v=embeddings.embed(["部署向量探针"]); print(len(v), len(v[0]))'
+```
+
+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 100m;
+}
+```
+
+`proxy_buffering off` 用于数字分身 SSE 流式吐字，`client_max_body_size` 同时用于知识库文件和聊天图片上传。应用只保存图片识别结果，不保存原图；识别结果 24 小时失效，后台默认每小时清理一次。公开分享图片识别会消耗分身所有者积分，生产网关应针对 `/api/public/avatar/*/chat/images` 设置每 IP 和每分享令牌的上传频率限制，防止恶意消耗。
+
+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、图片 Base64、病例正文或平台密钥。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、独立知识库和积分余额均存在。
+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，知识库优先级和积分扣费正常。
+7. 开启 BOXIM 主动接管后保持在线，默认三分钟回复、自定义等待时间、已读回执、分身防回环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。
+10. 微信和支付宝各创建一笔最小套餐订单，未付款时积分不变；支付成功后回调到账一次，重复回调积分不重复增加。
+11. 私聊和公开分享各上传 JPG、PNG、WebP 图片并完成追问；上传非图片、超过 8MB 或跨分身附件时必须拒绝。
+12. 病例图片可以提取可见文字并标记待核对内容，医学影像不作确定诊断；视觉与 OCR 调用分别扣减积分。
+13. 检查服务器上传目录不残留聊天原图，数据库过期图片识别记录在清理周期后删除，日志不出现 Base64 或病例正文。
+
+## 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。

+# 数字分身图片与病例理解详细设计
+
+## 1. 目标与边界
+
+本功能让数字分身在私聊和公开分享聊天中接收图片，并围绕图片内容继续使用现有的“标准答题对 -> 分身独立知识库 -> Qwen 兼容模型”链路回答。
+
+第一期支持 JPEG、PNG、WebP，覆盖以下场景：
+
+1. 普通照片、截图、图表和界面图片的内容理解。
+2. 病例、处方、检查单、检验报告等图片文档的文字和表格提取。
+3. X 光、CT、MRI 等医学影像的客观可见内容描述。
+
+第一期不把通用视觉模型的输出当作医学诊断，不自动把图片或病例写入知识库，不保存原图供长期访问，也不支持 DICOM 原始影像。
+
+## 2. 核心原则
+
+- **资料优先级不变**：标准答题对最高，分身独立知识库其次，图片识别结果属于待核对的会话资料，最后才由模型组织表达。
+- **病例最小留存**：应用不把原图写入业务存储，上传内容在内存中归一化并调用视觉服务；数据库只保存结构化结果和必要元数据。
+- **严格隔离**：每条图片记录必须绑定 `avatar_id`，私聊校验分身所有者，公开聊天校验分享令牌对应的分身。
+- **不确定性显式化**：OCR 看不清、表格列错位、医学影像无法确认时必须指出待核对项，不允许补齐缺失内容。
+- **可计量**：视觉理解和病例 OCR 分别计入分身所有者的积分消耗，失败时释放预留积分。
+- **可降级**：OCR 失败但通用视觉结果有效时仍可回答；视觉主调用失败则不进入聊天发送。
+
+## 3. 总体流程
+
+```text
+用户选择图片
+  -> 前端本地预览
+  -> 私聊/公开图片上传接口
+  -> 文件大小、MIME、真实格式、像素数校验
+  -> 自动旋转、缩放、去 EXIF、统一 JPEG
+  -> 通用视觉模型分类并输出结构化 JSON
+  -> 若为病例/检查单，再调用 OCR 模型精确转录
+  -> 保存结构化结果，不持久化原图
+  -> 返回 attachmentId
+  -> 用户发送文字 + attachmentIds
+  -> 标准答题对匹配
+  -> 用文字 + 图片提取结果检索独立知识库
+  -> 把标准答案、知识片段、图片资料注入系统上下文
+  -> Qwen SSE 流式回答
+```
+
+## 4. 模型编排
+
+### 4.1 通用视觉模型
+
+默认 `qwen3.6-flash`，可在后台数字分身专用模型配置中修改。输入为归一化后的 Base64 Data URL，要求返回 JSON：
+
+```json
+{
+  "category": "general_image|document|medical_document|medical_image",
+  "summary": "客观、完整的图片描述",
+  "visible_text": "图片中可确认的文字",
+  "key_facts": ["事实1", "事实2"],
+  "uncertainties": ["无法确认的内容"],
+  "medical": {
+    "document_type": "",
+    "patient_info": {},
+    "chief_complaint": "",
+    "findings": [],
+    "measurements": [],
+    "doctor_advice": ""
+  }
+}
+```
+
+模型提示词禁止诊断、补全被遮挡文字、猜测患者身份和输出模型信息。
+
+### 4.2 病例 OCR
+
+当 `category=medical_document` 时追加调用 `qwen-vl-ocr`，按原布局转录文字和表格。OCR 文本优先替换通用视觉输出中的 `visible_text`，但保留通用视觉模型提供的分类、摘要和不确定项。
+
+### 4.3 医学影像
+
+当 `category=medical_image` 时只保存客观描述，不输出疾病结论、分期、用药或治疗方案。聊天提示词必须要求结合正规影像报告和医生意见，并显示“图片识别结果仅供辅助，不能替代医生诊断”。
+
+## 5. 数据模型
+
+新增 `chat_attachments`：
+
+| 字段 | 说明 |
+|---|---|
+| `id` | 不可猜测的附件 ID |
+| `avatar_id` | 所属数字分身，强制隔离 |
+| `filename` | 原文件名，去除路径 |
+| `mime_type` / `file_size` | 上传元数据 |
+| `status` | `processing / ready / failed` |
+| `category` | 图片分类 |
+| `summary` | 通用视觉摘要 |
+| `extracted_text` | 可确认文字/OCR 结果 |
+| `structured_data` | 结构化 JSON |
+| `warning` | 不确定项和医学提示 |
+| `vision_model` / `ocr_model` | 实际调用模型 |
+| `created_at` / `used_at` | 创建和最近使用时间 |
+
+不保存公开原图 URL。应用层不落盘原图；框架上传缓冲在请求结束时关闭，处理结果在 24 小时后自动清理。
+
+## 6. API 设计
+
+### 6.1 上传并解析
+
+- `POST /api/avatar/{avatar_id}/chat/images`
+- `POST /api/public/avatar/{share_token}/chat/images`
+- `multipart/form-data: file`
+
+成功返回：
+
+```json
+{
+  "id": "attachment-id",
+  "filename": "病例.jpg",
+  "status": "ready",
+  "category": "medical_document",
+  "summary": "门诊检查单",
+  "warning": "部分手写内容需要人工核对"
+}
+```
+
+### 6.2 聊天
+
+原聊天接口增加：
+
+```json
+{
+  "message": "请帮我看看异常指标",
+  "attachmentIds": ["attachment-id"],
+  "history": [
+    {"role": "user", "content": "上一条问题", "attachmentIds": ["attachment-id"]}
+  ]
+}
+```
+
+当前消息最多 3 张图，历史最多引用最近 3 个不同附件。后端只读取与当前 `avatar_id` 相同且状态为 `ready` 的记录。
+
+## 7. 安全与隐私
+
+- 单图最大 8MB，解码后最大 1600 万像素，最长边归一化到 4096 像素以内。
+- 使用 Pillow 验证真实图片格式并防止解压炸弹；重新编码时清除 EXIF、GPS 和其他元数据。
+- 图片不会写入 FastAPI `StaticFiles` 或知识库目录，模型请求和日志不得输出 Base64 内容。
+- 日志只记录附件 ID、分身 ID、状态、耗时和模型，不记录图片 Base64、OCR 全文、病例内容或 API Key。
+- 公开分享上传仍消耗分身所有者积分；余额不足时拒绝视觉调用。
+- 生产环境需要补充用户授权、数据处理协议、存储地域和模型供应商留存策略确认。
+
+## 8. 前端交互
+
+- 输入框左侧增加图片按钮，支持相册选择和移动端拍照。
+- 选择后显示本地缩略图和“正在识别图片”，识别完成前禁止发送。
+- 用户可删除待发送图片；发送后图片保留在当前会话气泡中，但刷新页面后不恢复原图。
+- 病例和医学影像在输入区及回答下方显示辅助提示，不使用恐吓式红色告警。
+- 上传或识别失败时保留文字输入，明确提示重新选择图片，不产生空白消息。
+
+## 9. 配置
+
+数字分身专用模型配置新增：
+
+- `vision_model_version`，默认 `qwen3.6-flash`
+- `ocr_model_version`，默认 `qwen-vl-ocr`
+
+环境变量兜底：
+
+```dotenv
+VISION_MODEL=qwen3.6-flash
+VISION_OCR_MODEL=qwen-vl-ocr
+VISION_MAX_OUTPUT_TOKENS=2048
+VISION_TIMEOUT_SECONDS=90
+VISION_TOKEN_RESERVE=12000
+CHAT_IMAGE_MAX_BYTES=8388608
+CHAT_IMAGE_MAX_PIXELS=16000000
+CHAT_ATTACHMENT_RETENTION_HOURS=24
+CHAT_ATTACHMENT_CLEANUP_MINUTES=60
+```
+
+视觉调用复用数字分身专用配置的 `api_base_url` 和 `api_key`，不额外复制密钥。
+
+## 10. 验收标准
+
+1. 普通照片、截图和图表能够返回与图片一致的描述并支持追问。
+2. 病例图片可以提取标题、患者字段、检查结果、异常指标和医生意见，模糊内容明确标记待核对。
+3. 上传后服务器业务目录不残留原图，响应和日志不包含 Base64 或完整病例正文。
+4. A 分身无法引用 B 分身附件；公开分享令牌无法访问其他分身附件。
+5. 有图片时标准答题对仍作为最高优先级事实，知识库命中次之。
+6. 视觉与 OCR 积分分别结算，失败调用释放预留积分。
+7. SSE 打字效果、Markdown、用户头像、公开分享和纯文本聊天均无回归。
+8. CT、MRI、X 光回答不作确定诊断，并显示人工复核提示。

+# 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
