+## 文件汇总依赖
+
+自动汇总文件目录与页数功能使用轻量 Python 库读取 PDF、Word、Excel、PowerPoint 文件。
+Docker 或生产环境如需处理 `.7z` 与 `.rar` 压缩包，还需要安装系统 `7z`/`p7zip`
+命令，并确认以下命令可用：
+
+```bash
+7z
+7z i
+```
+
+LibreOffice 不是必需依赖，仅作为未来增强老格式文档解析的可选能力。
+
+上传原始文件、批次工作目录和导出文件默认存储在 Django `MEDIA_ROOT` 下的
+`file_summary/users/<user_id>/<conversation_id>/` 或批次 `work_dir` 目录中。生产环境
+需要把 `MEDIA_ROOT` 挂载到持久化卷，并纳入备份或归档策略。

+# 自动汇总前端线框图
+
+## 评审目标
+
+在实现三栏页面前，先确认审核智能体工作台的信息架构、右侧文件汇总面板、工作流状态展示和移动端降级方式。
+
+## 桌面端布局
+
+```mermaid
+flowchart LR
+    A["左栏：会话列表<br/>新对话 / 搜索 / 历史会话"] --> B["中栏：聊天区<br/>顶部导航 / 消息流 / 输入框"]
+    B --> C["右栏：文件汇总面板"]
+    C --> C1["上半区：上传区<br/>拖拽上传 / 选择文件 / 上传状态"]
+    C --> C2["中段：当前对话附件<br/>文件名 / 版本 / 大小 / 状态 / 删除"]
+    C --> C3["下半区：工作流卡片<br/>批次号 / 节点进度 / 下载入口"]
+```
+
+## 右侧面板结构
+
+```mermaid
+flowchart TB
+    P["文件汇总面板"] --> U["上传拖拽区"]
+    U --> U0["无附件：提示上传文件或压缩包"]
+    U --> U1["上传中：显示文件名和处理中状态"]
+    U --> U2["上传失败：展示错误并允许重试"]
+    P --> L["附件列表"]
+    L --> L1["active 版本优先展示"]
+    L --> L2["历史版本保留展示"]
+    L --> L3["逻辑删除后从默认候选移除"]
+    P --> W["工作流卡片列表"]
+    W --> W1["运行中：节点逐项更新"]
+    W --> W2["成功：展示 Markdown/Excel 下载"]
+    W --> W3["失败：展示失败节点和错误说明"]
+```
+
+## 工作流状态流转
+
+```mermaid
+stateDiagram-v2
+    [*] --> Pending: 用户上传附件
+    Pending --> Running: 发送自动汇总提示词
+    Running --> Extracting: 固化附件
+    Extracting --> Scanning: 解压完成或跳过
+    Scanning --> Counting: 生成文件清单
+    Counting --> Detecting: 页数统计完成
+    Detecting --> Reporting: 产品名识别完成
+    Reporting --> Success: 生成报告与下载
+    Running --> Failed: 批次级异常
+    Extracting --> Failed: 解压安全检查失败
+    Reporting --> Failed: 报告生成失败
+    Success --> Restored: 刷新页面后状态恢复
+    Failed --> Restored: 刷新页面后状态恢复
+```
+
+## 移动端布局
+
+```mermaid
+flowchart TB
+    M["移动端工作台"] --> T["顶部：侧栏按钮 / 当前页面 / 用户菜单"]
+    T --> Chat["聊天区优先展示"]
+    Chat --> Composer["底部输入框"]
+    T --> Drawer["会话侧栏抽屉"]
+    Chat --> Panel["文件汇总面板下移或折叠"]
+    Panel --> Upload["上传区"]
+    Panel --> Workflow["工作流卡片"]
+```
+
+## 关键评审点
+
+- 桌面端保持左侧会话、中间聊天、右侧文件汇总三栏，不改变现有聊天主路径。
+- 右侧面板上半部分用于上传和附件列表，下半部分用于批次工作流卡片。
+- 工作流卡片节点顺序固定为：附件固化、压缩包解压、文件扫描、页数统计、产品识别、报告输出、完成。
+- 助手消息中的文件汇总结果使用安全 Markdown 渲染，用户消息仍按纯文本转义。
+- 移动端优先保证聊天可用，文件汇总面板折叠或下移，不能遮挡输入框。
