Subject: [PATCH] feat(pkb): Complete PKB module frontend migration with V3
 design

Summary:
- Implement PKB Dashboard and Workspace pages based on V3 prototype
- Add single-layer header with integrated Tab navigation
- Implement 3 work modes: Full Text, Deep Read, Batch Processing
- Integrate Ant Design X Chat component for AI conversations
- Create BatchModeComplete with template selection and document processing
- Add compact work mode selector with dropdown design

Backend:
- Migrate PKB controllers and services to /modules/pkb structure
- Register v2 API routes at /api/v2/pkb/knowledge
- Maintain dual API routes for backward compatibility

Technical details:
- Use Zustand for state management
- Handle SSE streaming responses for AI chat
- Support document selection for Deep Read mode
- Implement batch processing with progress tracking

Known issues:
- Batch processing API integration pending
- Knowledge assets page navigation needs optimization

Status: Frontend functional, pending refinement

+
+**检查项**：
+1. ✅ URL是否正确（是否包含 `-plain` 后缀）
+2. ✅ Token是否与环境变量一致
+3. ✅ 消息加解密方式是否选择"明文模式"
+4. ✅ natapp是否正常运行
+5. ✅ 服务器是否正常运行
+
+### 问题3: 服务器日志无响应
+
+**可能原因**：
+1. ❌ natapp未启动或配置错误
+2. ❌ 服务器未启动
+3. ❌ 路由未注册
+4. ❌ 防火墙拦截
+
+**排查步骤**：
+```powershell
+# 1. 测试健康检查接口
+curl https://devlocal.xunzhengyixue.com/api/v1/iit/health
+
+# 2. 测试明文模式路由（通过natapp）
+.\test-wechat-mp-plain.ps1
+
+# 3. 测试直接访问localhost
+curl http://localhost:3001/api/v1/iit/health
+```

+# **AI 临床医生与医院知识库 \- MVP 阶段产品需求文档 (PRD) V5.0**
+
+|
+
+| 版本号 | 日期 | 修改人 | 修改内容 |  
+| V4.0 | 2024-06-XX | Product Lead | 降维策略 MVP |  
+| V5.0 | 2024-06-XX | Product Lead | 完整落地版：基于“全量阅读”策略，补全 UI/UX 规范与详细功能定义 |
+
+## **1\. 核心战略与范围 (Strategy & Scope)**
+
+### **1.1 核心价值主张**
+
+放弃传统的“切片式 RAG”，利用 DeepSeek-V3 / Qwen-Max 的长窗口能力，通过 **Document-Level RAG (文档级阅读)** 技术，为医生提供**逻辑完整、引用精准**的知识库问答体验。
+
+### **1.2 MVP 阶段边界 (Scope Freeze)**
+
+* **适用终端:** Web 端 (PC/Mac 浏览器)，兼容 iPad。  
+* **支持格式:** PDF, Word (.docx), PPT (.pptx)。  
+* **硬性限制:** 单库文件数 ≤ 30 个；单文件大小 ≤ 20MB。  
+* **核心场景:** 循证检索 (指南)、深度研读 (文献)、用药助手 (药品)、考典刷题 (考试)。
+
+## **2\. 功能模块详情 (Detailed Requirements)**
+
+### **2.1 模块一：仪表盘 (Dashboard)**
+
+**用户故事:** 作为医生，我希望一眼看到我有多少个知识库，并能快速创建一个新的专科知识库。
+
+#### **2.1.1 页面布局与 UI 规范**
+
+* **布局结构:**  
+  * **顶部:** 全局导航栏 (Logo \+$$智能统计$$$$智能清洗$$$$\*\*AI 知识库\*\*$$$$AI 问答$$  
+    \+ 头像)。  
+  * **主体:** "1+3" 卡片阵列布局 (Grid System)。  
+* **卡片设计:**  
+  * **Slot 1 (新建入口):**  
+    * **样式:** 浅蓝色渐变背景 (bg-blue-50)，深蓝色虚线边框。  
+    * **内容:** 大号 "+" 图标，文案 "创建知识库"，下方并列展示 5 个场景图标 (指南/文献/病例/药品/考试) 以提示能力。  
+  * **Slot 2-N (现有知识库):**  
+    * **样式:** 白色卡片，微阴影 (shadow-sm \-\> hover shadow-md)。  
+    * **内容:** 图标(左上) \+ 标题(加粗) \+ 类型标签(胶囊样式) \+ "进入工作台"按钮(底部通栏)。
+
+#### **2.1.2 交互流程：创建知识库**
+
+* **触发:** 点击“创建知识库”卡片 \-\> 弹出模态框 (Modal)。  
+* **Step 1: 类型选择 (Type Selection)**  
+  * **UI:** 5 个大卡片网格。  
+  * **选项:**  
+    1. **循证检索 (指南):** 图标 BookOpen (Blue)。文案："查诊疗标准、用药剂量"。  
+    2. **深度研读 (文献):** 图标 Microscope (Purple)。文案："文献综述、横向对比"。  
+    3. **临床决策 (病例):** 图标 Stethoscope (Green)。文案："疑难病例参考"。  
+    4. **用药助手 (药品):** 图标 Pill (Rose)。文案："查配伍禁忌"。  
+    5. **考典刷题 (考试):** 图标 GraduationCap (Orange)。文案："主治/副高备考"。  
+* **Step 2: 基础信息 & 角色注入**  
+  * **字段:** 知识库名称 (必填)、所属科室 (下拉选：心内/呼吸/消化...)。  
+  * **逻辑:** 选中“心内科”后，后端自动在 System Prompt 中注入 *"你是一名心内科专家..."*。  
+* **Step 3: 文件上传 (Upload)**  
+  * **UI:** 大面积拖拽上传区 (Dropzone)。  
+  * **逻辑:**  
+    * 前端校验大小 (\>20MB 飘红报错)。  
+    * 前端校验数量 (\>30 个 飘红报错)。  
+    * 上传成功后显示列表，状态流转：上传中... \-\> 就绪。
+
+### **2.2 模块二：沉浸式工作台 (Workspace)**
+
+**用户故事:** 作为医生，我希望在一个无干扰的环境中与我的资料对话，并能随时核对原文。
+
+#### **2.2.1 全局框架 (Immersive Layout)**
+
+* **顶部导航 (Header):**  
+  * **样式:** 深色背景 (bg-slate-900)，高度 56px。  
+  * **左侧:** \< 返回 (白色文字按钮，点击返回 Dashboard)。  
+  * **中间:** 知识库名称 \+ 图标。  
+  * **右侧:** 简单的设置齿轮。  
+* **模式切换 (Tabs):**  
+  * 位于 Header 下方，白色背景，高度 48px。  
+  * **Tab A:** \[💬 智能问答\] (默认选中，底部蓝条)。  
+  * **Tab B:** \[📂 知识资产\] (显示文件计数 Badge)。
+
+#### **2.2.2 视图 A：智能问答 (Smart Chat)**
+
+* **布局:**  
+  * **默认:** 单栏宽屏聊天窗口 (最大宽度 900px，居中)。  
+  * **扩展:** 当点击引用或手动展开时，右侧滑出 PDF 阅读器 (占比 45%)，聊天窗自动收缩至左侧。  
+* **对话交互 (Chat Interaction):**  
+  * **输入框:** 底部固定。支持 Shift+Enter 换行。  
+  * **AI 回答:** 流式输出 (Typewriter Effect)。  
+  * **引用标注:** 必须以 \[文档名\] 或 \[1\] 形式高亮显示，颜色为品牌蓝。  
+* **后端策略路由 (核心逻辑):**  
+  * **场景一 (小库直读):** 知识库总 Token \< 32k。  
+    * *UI:* 顶部 Toast 提示 "已加载全量上下文，AI 具备全知视角"。  
+  * **场景二 (大库路由):** 知识库总 Token \> 32k。  
+    * *UI:* 用户提问后，输入框上方出现微型 Loading 状态 —— "正在分析摘要..." \-\> "已定位至《2024指南》等 3 篇文档" \-\> 开始回答。
+
+#### **2.2.3 视图 B：知识资产 (Assets Management)**
+
+* **UI 形式:** 全屏数据表格 (Table)。  
+* **列定义:**  
+  1. **文件名:** 图标 (PDF/Word) \+ 名称。  
+  2. **AI 摘要:** 展示 2-3 行核心摘要文本 (由 DeepSeek 生成)，支持 hover 查看全部。  
+  3. **状态:** 准备中 (灰色) / 就绪 (绿色) / 失败 (红色)。  
+  4. **操作:** 预览、删除。  
+* **筛选器:** 右上角“筛选”按钮，点击弹出下拉面板 (按时间/状态/类型)。
+
+## **3\. 详细 UI/UX 设计规范 (Design Specs)**
+
+为确保还原度，请 UI 设计师和前端开发遵循以下规范：
+
+### **3.1 色彩体系 (Color Palette)**
+
+使用 Tailwind CSS 默认色板：
+
+* **主色 (Primary):** Blue-600 (\#2563EB) \- 用于按钮、链接、高亮。  
+* **场景色 (Category Colors):**  
+  * 指南: Blue-500  
+  * 文献: Purple-600  
+  * 病例: Emerald-600  
+  * 药品: Rose-600  
+  * 考试: Orange-500  
+* **中性色:** Slate-50 (背景), Slate-900 (Header), Slate-500 (次要文字)。
+
+### **3.2 图标系统 (Iconography)**
+
+* **风格:** 线性图标 (Stroke 2px)。  
+* **技术:** 使用 **Inline SVG** (参考 TDD V3.0 的 Icons 常量)，严禁引入外部 Icon Font。
+
+### **3.3 字体与排版**
+
+* **字体:** 系统默认无衬线字体 (Inter, Roboto, PingFang SC)。  
+* **字号:**  
+  * H1 (页面标题): 20px Bold  
+  * H2 (模块标题): 16px Bold  
+  * Body (正文): 14px Regular (行高 1.6)  
+  * Caption (说明): 12px Text-Slate-400
+
+## **4\. 异常流程与边界处理 (Exception Handling)**
+
+### **4.1 上传失败**
+
+* **场景:** 用户上传了加密 PDF 或损坏文件。  
+* **后端:** 解析器捕获异常，返回 status: FAILED，error\_msg: "File encrypted"。  
+* **前端:** 资产列表中该行变红，显示“解析失败：文件已加密”，并提供“删除”按钮。
+
+### **4.2 AI 回答超时/失败**
+
+* **场景:** DeepSeek API 响应超时 (\>60s)。  
+* **UI:**  
+  * 消息气泡显示红色感叹号。  
+  * 提示文案: "AI 思考超时，请尝试精简问题或重试。"  
+  * 提供$$重试$$  
+    按钮。
+
+### **4.3 引用源定位失败**
+
+* **场景:** 用户点击 \[1\]，但该文件已被删除。  
+* **UI:** 弹出 Toast 提示 "源文件已被删除，无法查看原文"。
+
+## **5\. 验收测试标准 (QA Acceptance)**
+
+| ID | 测试点 | 预期结果 | 优先级 |  
+| TC01 | 格式兼容性 | 上传 .pdf, .docx, .pptx 文件，均能在资产列表显示“就绪”，且能被检索到。 | P0 |  
+| TC02 | 边界限制 | 尝试上传第 31 个文件，前端应阻止上传并弹窗提示限制。 | P0 |  
+| TC03 | 引用跳转 | 提问后，点击回答中的 \[文档名\]，右侧面板应滑出并正确加载该文档。 | P0 |  
+| TC04 | Word表格解析 | 上传包含表格的 Word 指南，询问表格内数据，AI 应能准确回答数值。 | P1 |  
+| TC05 | 路由逻辑 | 在 \>32k Token 的库中提问，观察 Network 请求，应看到系统先请求了摘要接口，再请求了全文接口。 | P1 |

+# **与原型图的差距**
+
+文档目的： 修正开发实现效果（图 17.png）与产品设计稿（图 18.png）之间的视觉差距，提升产品精致度。  
+优先级： High (P0) \- 影响视觉体验的核心问题
+
+## **1\. 总体布局与间距 (Global Layout & Spacing)**
+
+设计稿强调了清晰的层级和呼吸感，而实现版本的元素过于紧凑，导致界面显得拥挤。
+
+* **页面边距 (Page Margins):**  
+  * **问题:** 实现版左右边距似乎过窄（或不一致），导致内容贴边。  
+  * **修改:** 全局内容区域（Container）的左右 Padding 需要统一，建议设置为 16px 或 20px（请参考设计稿具体数值），保持视觉平衡。  
+* **卡片/区块间距:**  
+  * **问题:** 列表项或卡片之间的垂直间距过小。  
+  * **修改:** 增加卡片/列表项之间的 margin-bottom，确保内容块之间有明显的区分。
+
+## **2\. 字体与排版 (Typography)**
+
+这是造成视觉差异最大的部分。实现版本文字层级拉不开，重点不突出。
+
+* **标题文字 (Headings):**  
+  * **问题:** 实现版的标题字重（Font Weight）不足，且字号可能偏小。  
+  * **修改:** 加大标题字重，使用 font-weight: 600 (Semi-bold) 或 bold。微调字号大小，确保与设计稿一致。  
+* **正文/辅助文字 (Body/Secondary Text):**  
+  * **问题:** 辅助信息（如日期、标签、描述）颜色过深，导致与标题抢夺视线。  
+  * **修改:**  
+    * 将主要文字颜色调整为深灰（如 \#333333 或 \#1F2937）。  
+    * 将辅助文字（次要信息）颜色调整为浅灰（如 \#666666 或 \#9CA3AF），拉开层级。  
+* **行高 (Line Height):**  
+  * **问题:** 多行文本的行间距过密，阅读体验差。  
+  * **修改:** 增加 line-height，建议设置为字号的 1.4 至 1.5 倍。
+
+## **3\. 组件与视觉样式 (Components & Visual Styles)**
+
+* **圆角 (Border Radius):**  
+  * **问题:** 实现版的按钮、卡片或图片的圆角看起来比较直（或者圆角数值不对）。  
+  * **修改:** 统一圆角大小。如果设计稿是 8px 或 12px，请确保 CSS 中严格执行，不要使用默认的直角。  
+* **阴影与边框 (Shadows & Borders):**  
+  * **问题:** 设计稿中可能运用了轻微的投影来增加立体感，或者使用了极细的分隔线，而实现版本可能丢失了阴影，或者边框颜色过深。  
+  * **修改:**  
+    * 如果是卡片设计，添加轻微的 box-shadow（例如 0 2px 8px rgba(0,0,0,0.05)）。  
+    * 分隔线颜色应更淡，建议使用 \#E5E7EB 或类似极浅灰色。  
+* **图片/图标 (Images & Icons):**  
+  * **问题:** 图片比例可能失调（被拉伸或压缩），或者图标位置未居中对齐。  
+  * **修改:**  
+    * 图片设置 object-fit: cover 防止变形。  
+    * 检查图标与文字的垂直对齐方式（flex 布局下使用 align-items: center）。
+
+## **4\. 导航与顶部栏 (Navigation/Header)**
+
+* **状态栏/顶部栏:**  
+  * **问题:** 顶部栏的高度可能不足，或者背景色与设计稿有色差。  
+  * **修改:** 校验顶部栏高度（Height），确保标题文字在垂直方向绝对居中。
+
+### **修改建议总结 (Action Items for Engineers)**
+
+1. **CSS 变量化:** 建议将设计稿中的**主色、辅色、字号标准、圆角值**定义为 CSS 变量（Variables），避免硬编码（Hard-coding），防止不一致。  
+2. **Flexbox 对齐:** 检查所有列表项，确保使用 display: flex 并正确设置 align-items: center，解决图标与文字的高低差问题。  
+3. **盒子模型检查:** 打开浏览器开发者工具，逐个核对 Padding 和 Margin 值，不要凭感觉估算。

+# PKB前端问题修复报告
+
+## 📋 问题概述
+
+**报告时间**: 2026-01-06  
+**修复状态**: ✅ **已全部修复**  
+**问题来源**: 用户反馈 + 原型图对比
+
+---
+
+## 🐛 发现的4个问题
+
+### 问题1：页面不是全屏，顶部有导航栏 ❌
+**现象**: 进入Workspace页面后，顶部仍然显示平台的全局导航栏
+
+**原因**: WorkspacePage被包裹在`MainLayout`中，导致继承了外层布局
+
+**影响**: 
+- 不符合V3设计的"沉浸式"体验
+- 浪费屏幕空间
+- 与原型图不一致
+
+---
+
+### 问题2：没有上下滚动条 ❌
+**现象**: Chat消息区域无法滚动，内容超出时看不到
+
+**原因**: 
+- 容器没有正确设置`overflow`属性
+- 高度计算不正确
+
+**影响**: 
+- 无法查看历史消息
+- 用户体验极差
+
+---
+
+### 问题3：Tab导航高度太高 ❌
+**现象**: "智能问答"和"知识资产"Tab导航栏高度过高，显得粗糙
+
+**原因**: 
+- 使用了`h-14`（56px）而非原型的`h-12`（48px）
+- 图标和文字尺寸过大
+
+**影响**: 
+- 与原型图不一致
+- 视觉效果不精致
+
+---
+
+### 问题4：AI对话报错 - JSON格式错误 ❌
+**现象**: 发送消息后报错：`Unexpected token 'd', "data: {"co"... is not valid JSON`
+
+**原因**: 
+- 后端返回的是SSE（Server-Sent Events）流式格式
+- 前端使用`response.json()`解析，导致格式错误
+- 没有正确处理`data: `前缀
+
+**影响**: 
+- 完全无法使用AI对话功能
+- 核心功能不可用
+
+---
+
+## ✅ 修复方案
+
+### 修复1：实现全屏沉浸式布局
+
+#### 代码修改
+```typescript
+// frontend-v2/src/modules/pkb/pages/WorkspacePage.tsx
+
+interface WorkspacePageProps {
+  standalone?: boolean; // 新增standalone模式
+}
+
+const WorkspacePage: React.FC<WorkspacePageProps> = ({ standalone = false }) => {
+  // 如果是standalone模式，使用固定定位覆盖整个屏幕
+  const containerClass = standalone 
+    ? "fixed inset-0 z-50 flex flex-col bg-gray-50"  // 全屏覆盖
+    : "flex flex-col h-screen bg-gray-50";           // 普通模式
+
+  return (
+    <div className={containerClass}>
+      {/* ... */}
+    </div>
+  );
+};
+```
+
+```typescript
+// frontend-v2/src/modules/pkb/index.tsx
+
+<Routes>
+  <Route path="/" element={<Navigate to="dashboard" replace />} />
+  <Route path="dashboard" element={<DashboardPage />} />
+  {/* Workspace页面全屏独立，不使用外层Layout */}
+  <Route path="workspace/:kbId" element={<WorkspacePage standalone />} />
+</Routes>
+```
+
+#### 效果
+✅ Workspace页面完全覆盖屏幕  
+✅ 没有顶部导航栏  
+✅ 沉浸式体验
+
+---
+
+### 修复2：正确设置滚动条
+
+#### 代码修改

+<main className="flex-1 overflow-hidden relative">
+  {activeTab === 'chat' && (
+    <div className="h-full flex overflow-hidden">  {/* 添加overflow-hidden */}
+      <div className="flex-1 flex flex-col bg-white overflow-hidden">
+        {/* 工作模式选择器 */}
+        <div className="p-3 border-b border-gray-100 flex-shrink-0">
+          {/* ... */}
+        </div>
+
+        {/* Chat区域 - 可滚动 */}
+        <div className="flex-1 overflow-y-auto">  {/* 添加overflow-y-auto */}
+          {/* ... */}
+        </div>
+      </div>
+    </div>
+  )}
+</main>
+```
+
+```typescript
+// FullTextMode.tsx
+<div className="h-full flex flex-col overflow-hidden">
+  <div className="flex-shrink-0 px-4 pt-4">  {/* 固定区域 */}
+    <Alert {...} />
+  </div>
+  
+  <div className="flex-1 overflow-hidden px-4 pb-4">  {/* 可滚动区域 */}
+    <ChatContainer {...} />
+  </div>
+</div>
+```
+
+#### 效果
+✅ Chat消息区域可以正常滚动  
+✅ 工作模式选择器固定在顶部  
+✅ 滚动条样式美观
+
+---
+

+data: {"content":"您","role":"assistant"}
+data: {"content":"好","role":"assistant"}
+data: {"content":"！","role":"assistant"}
+data: [DONE]
+```
+
+前端错误代码：
+```typescript
+// ❌ 错误：直接使用response.json()
+const data = await response.json();
+```
+
+#### 修复代码
+```typescript
+// FullTextMode.tsx & DeepReadMode.tsx
+
+requestFn: async (message: string) => {
+  const response = await fetch('/api/v1/chat/stream', {
+    method: 'POST',
+    headers: { 
+      'Content-Type': 'application/json',
+      'Accept': 'text/event-stream',  // 🌟 关键：指定SSE格式
+    },
+    body: JSON.stringify({
+      content: message,
+      modelType: 'qwen-long',  // 使用qwen-long模型
+      knowledgeBaseIds: [kbId],
+      fullTextDocumentIds,  // 或 documentIds
+    }),
+  });
+  
+  if (!response.ok) {
+    throw new Error(`API请求失败: ${response.status}`);
+  }
+  
+  // 🌟 正确处理流式响应
+  const reader = response.body?.getReader();
+  const decoder = new TextDecoder();
+  let fullContent = '';
+  
+  if (reader) {
+    while (true) {
+      const { done, value } = await reader.read();
+      if (done) break;
+      
+      const chunk = decoder.decode(value);
+      const lines = chunk.split('\n');
+      
+      for (const line of lines) {
+        if (line.startsWith('data: ')) {
+          const data = line.slice(6);  // 移除"data: "前缀
+          if (data === '[DONE]') break;
+          
+          try {
+            const json = JSON.parse(data);
+            if (json.content) {
+              fullContent += json.content;  // 累积内容
+            }
+          } catch (e) {
+            // 忽略解析错误
+          }
+        }
+      }
+    }
+  }
+  
+  return {
+    content: fullContent,
+    messageId: Date.now().toString(),
+  };
+}
+```

+
+## 🎯 技术要点总结
+
+### 1. 全屏沉浸式布局
+**关键技术**:
+- `fixed inset-0 z-50`：固定定位，覆盖整个视口
+- `standalone` prop：控制是否使用全屏模式
+- 独立路由：不包裹在MainLayout中
+
+### 2. 滚动容器层级
+**正确的层级结构**:
+```
+<main className="flex-1 overflow-hidden">           {/* 外层：隐藏溢出 */}
+  <div className="h-full flex overflow-hidden">     {/* 中层：固定高度 */}
+    <div className="flex-1 overflow-y-auto">        {/* 内层：可滚动 */}
+      {/* 内容 */}
+    </div>
+  </div>
+</main>
+```
+
+### 3. SSE流式响应处理
+**关键步骤**:
+1. 设置正确的请求头：`Accept: text/event-stream`
+2. 使用`ReadableStream` API读取响应
+3. 逐行解析`data: `格式
+4. 累积内容片段
+5. 处理`[DONE]`结束标记
+
+### 4. 精确还原设计
+**设计规范**:
+- 高度：严格使用Tailwind的h-12、h-14等
+- 图标：w-4 h-4（16px）
+- 文字：text-sm（14px）
+- 间距：p-3（12px）

+4. **批处理模式**: 实现批处理功能的完整流程
+
+---
+
+## 💡 经验教训
+
+### 1. 设计还原要精确
+- 不能"差不多"，要"完全一致"
+- 每个像素都要对比原型图
+- 使用Tailwind的精确尺寸类
+
+### 2. 全屏页面需要特殊处理
+- 不能简单地放在MainLayout中
+- 需要`fixed`定位或独立路由
+- 考虑z-index层级
+
+### 3. 滚动容器要仔细设计
+- 外层`overflow-hidden`
+- 内层`overflow-y-auto`
+- 固定区域`flex-shrink-0`
+
+### 4. API格式要与后端对齐
+- 仔细查看后端代码
+- 理解SSE流式格式
+- 正确处理流式数据

+### 1.4 关键业务逻辑
+
+#### 配额管理
+```typescript
+// 用户表（在platform_schema.users）中的字段
+kbQuota: Int @default(3)   // 知识库配额
+kbUsed: Int @default(0)    // 已使用数量
+
+// 创建知识库时检查
+if (user.kbUsed >= user.kbQuota) {
+  throw new Error('配额已满');
+}
+
+// 创建成功后增加计数
+await prisma.user.update({
+  data: { kbUsed: { increment: 1 } }
+});
+
+// 删除知识库时减少计数
+await prisma.user.update({
+  data: { kbUsed: { decrement: 1 } }
+});
+```
+
+#### Dify集成
+```typescript
+// 创建知识库 → 创建Dify Dataset
+const difyDataset = await difyClient.createDataset({
+  name: `${userId}_${name}_${Date.now()}`,
+  description,
+  indexing_technique: 'high_quality',
+});
+
+// 检索知识库 → 调用Dify RAG
+const results = await difyClient.retrieveKnowledge(
+  difyDatasetId,
+  query,
+  {
+    retrieval_model: {
+      search_method: 'semantic_search',
+      top_k: 15,
+    },
+  }
+);
+```
+
+#### 文档Token计算（tokenService.ts）
+```typescript
+// Token计算规则
+const TOKEN_LIMITS = {
+  MAX_FILES: 7,           // 最多7篇文献
+  MAX_TOTAL_TOKENS: 750000, // 总Token限制（Qwen-Long: 1M上下文 - 250K对话空间）
+  MAX_SINGLE_DOC_TOKENS: 200000, // 单篇文献最大Token数
+};
+
+// 智能选择算法
+function selectDocumentsForFullText(
+  documentTokens,
+  maxFiles,
+  maxTokens
+) {
+  // 按Token数升序排序
+  const sorted = documentTokens.sort((a, b) => a.tokens - b.tokens);
+  
+  // 贪心算法选择
+  let totalTokens = 0;
+  let selectedCount = 0;
+  const selected = [];
+  
+  for (const doc of sorted) {
+    if (selectedCount >= maxFiles) break;
+    if (totalTokens + doc.tokens > maxTokens) break;
+    if (doc.tokens > MAX_SINGLE_DOC_TOKENS) continue; // 跳过超大文档
+    
+    selected.push(doc);
+    totalTokens += doc.tokens;
+    selectedCount++;
+  }
+  
+  return { selected, totalTokens, excludedDocs };
+}

+   └─ BatchMode.tsx       # 批处理模式组件
+```
+
+### 2.2 三种工作模式详解
+
+#### 模式1：全文阅读模式（Full Text Mode）
+
+**用途**：35-50篇文献的综合分析
+
+**实现原理：**
+```typescript
+// 1. 前端：用户进入知识库模式 → 选择"全文阅读"
+const modeState = {
+  baseMode: 'knowledge_base',
+  kbMode: 'full_text',
+  selectedKbId: 'xxx',
+};
+
+// 2. 前端：智能加载文献
+const selection = await knowledgeBaseApi.getDocumentSelection(kbId, {
+  max_files: 7,
+  max_tokens: 750000,
+});
+// 返回：{ selectedDocuments[], excludedDocuments[], totalTokens }
+
+// 3. 前端：自动切换到Qwen-Long模型
+if (modeState.kbMode === 'full_text') {
+  setSelectedModel('qwen-long'); // 1M上下文
+  showToast('已自动切换到Qwen-Long模型（支持1M上下文）');
+}
+
+// 4. 前端：发送消息时传递文档ID列表
+await chatApi.sendMessageStream({
+  content: userQuestion,
+  modelType: 'qwen-long',
+  fullTextDocumentIds: loadedDocs.map(d => d.id), // ✅ 关键参数
+  conversationId,
+});
+
+// 5. 后端：加载完整全文
+if (fullTextDocumentIds && fullTextDocumentIds.length > 0) {
+  const documents = await prisma.document.findMany({
+    where: { id: { in: fullTextDocumentIds } },
+    select: { id, filename, extractedText, tokensCount },
+  });
+  
+  // 6. 组装全文上下文
+  const fullTextParts = [];
+  for (let i = 0; i < documents.length; i++) {
+    const doc = documents[i];
+    const docNumber = i + 1;
+    
+    // 格式：【文献N：文件名】\n全文内容
+    fullTextParts.push(
+      `【文献${docNumber}：${doc.filename}】\n\n${doc.extractedText}`
+    );
+    
+    // 添加引用信息
+    allCitations.push({
+      id: docNumber,
+      fileName: doc.filename,
+      score: 1.0, // 全文相关度100%
+      content: doc.extractedText.substring(0, 200),
+    });
+  }
+  
+  knowledgeBaseContext = fullTextParts.join('\n\n---\n\n');
+}
+
+// 7. 传递给LLM
+const systemPrompt = '你是专业的学术文献分析助手。每篇文献用【文献N：文件名】标记。请认真阅读所有文献，进行深入的综合分析。在回答时请引用具体文献，使用【文献N】格式。';
+
+const userContent = `${userQuestion}\n\n## 参考资料（文献全文）\n\n${knowledgeBaseContext}`;
+
+const messages = [
+  { role: 'system', content: systemPrompt },
+  ...historyMessages, // 对话历史
+  { role: 'user', content: userContent },
+];
+
+// 8. 调用Qwen-Long
+const response = await LLMFactory.getAdapter('qwen-long').chatStream(messages, {
+  temperature: 0.7,
+  maxTokens: 6000, // 全文模式需要更长的回答空间
+});
+```
+
+**关键特点：**
+- ✅ 传递完整全文（不是RAG片段）
+- ✅ 智能选择文献（基于Token限制）
+- ✅ 文献来源标记：【文献N：文件名】
+- ✅ 自动切换到Qwen-Long模型（1M上下文）
+- ✅ 100%相关度（因为是全文）
+- ✅ 适合跨文献比较、趋势分析、研究方法归纳
+
+**Token使用：**
+```
+上下文：~750K tokens（7篇文献全文）
+对话空间：~250K tokens
+输出长度：6000 tokens（综合分析需要更长回答）
+```
+
+---
+
+#### 模式2：逐篇精读模式（Deep Read Mode）
+
+**用途**：1-5篇文献的深度分析
+
+**实现原理：**
+```typescript
+// 1. 前端：用户选择"逐篇精读"
+const modeState = {
+  baseMode: 'knowledge_base',
+  kbMode: 'deep_read',
+  selectedKbId: 'xxx',
+};
+
+// 2. 前端：用户选择要精读的文档
+const selectedDocs = [doc1, doc2, doc3]; // 用户手动选择
+
+// 3. 前端：切换到某个文档
+const currentDoc = selectedDocs[0];
+
+// 4. 前端：发送消息时传递当前文档ID（用于RAG过滤）
+await chatApi.sendMessageStream({
+  content: userQuestion,
+  modelType: selectedModel,
+  knowledgeBaseIds: [kbId], // 知识库ID
+  documentIds: [currentDoc.id], // ✅ 关键：只检索当前文档
+  conversationId: currentDocConversationId, // 每个文档独立对话
+});
+
+// 5. 后端：RAG检索（限定在特定文档）
+if (documentIds && documentIds.length > 0) {
+  // 调用Dify RAG，但会限定在指定文档范围
+  const results = await difyClient.retrieveKnowledge(
+    difyDatasetId,
+    query,
+    {
+      retrieval_model: {
+        search_method: 'semantic_search',
+        top_k: 15,
+        document_ids: documentIds, // ✅ Dify会只检索这些文档
+      },
+    }
+  );
+}
+```
+
+**关键特点：**
+- ✅ 基于RAG检索（不是全文）
+- ✅ 限定在当前文档范围
+- ✅ 每个文档有独立的对话历史
+- ✅ 用户可以在文档间切换
+- ✅ 适合深度理解单篇文献
+
+---
+
+#### 模式3：批处理模式（Batch Mode）
+
+**用途**：3-50篇文献的批量信息提取
+
+**实现原理：**
+```typescript
+// 1. 用户创建批处理任务
+POST /api/v1/batch-tasks/create
+Body: {
+  kbId: 'xxx',
+  name: '提取研究方法',
+  prompt: '请从这篇文献中提取：研究设计、样本量、统计方法',
+  templateType: 'custom' | 'preset',
+  modelType: 'deepseek-v3',
+  concurrency: 3, // 并发数
+}
+
+// 2. 后端：创建任务
+const task = await prisma.batchTask.create({
+  data: {
+    userId,
+    kbId,
+    name,
+    prompt,
+    templateType,
+    modelType,
+    status: 'pending',
+    totalDocuments: documentsCount,
+    concurrency,
+  },
+});
+
+// 3. 后端：启动批处理Worker
+async function processBatchTask(taskId) {
+  // 3.1 获取任务和文档列表
+  const task = await prisma.batchTask.findUnique({
+    where: { id: taskId },
+    include: { knowledgeBase: { include: { documents: true } } },
+  });
+  
+  const documents = task.knowledgeBase.documents.filter(d => d.status === 'completed');
+  
+  // 3.2 更新任务状态
+  await prisma.batchTask.update({
+    where: { id: taskId },
+    data: { status: 'running', startedAt: new Date() },
+  });
+  
+  // 3.3 并发处理文档
+  const concurrency = task.concurrency || 3;
+  const chunks = chunkArray(documents, concurrency);
+  
+  for (const chunk of chunks) {
+    await Promise.all(chunk.map(async (doc) => {
+      try {
+        // 3.3.1 对每个文档，使用其extractedText + prompt调用LLM
+        const llmPrompt = `${task.prompt}\n\n文献内容：\n${doc.extractedText}`;
+        
+        const response = await LLMFactory.getAdapter(task.modelType).chat([
+          { role: 'user', content: llmPrompt },
+        ]);
+        
+        // 3.3.2 解析LLM输出（期望JSON格式）
+        const data = parseJSONResponse(response.content);
+        
+        // 3.3.3 保存结果
+        await prisma.batchResult.create({
+          data: {
+            taskId: task.id,
+            documentId: doc.id,
+            status: 'success',
+            data,
+            rawOutput: response.content,
+            tokensUsed: response.usage.totalTokens,
+            processingTimeMs: Date.now() - startTime,
+          },
+        });
+        
+        // 3.3.4 更新任务进度
+        await prisma.batchTask.update({
+          where: { id: taskId },
+          data: { completedCount: { increment: 1 } },
+        });
+        
+      } catch (error) {
+        // 3.3.5 处理失败
+        await prisma.batchResult.create({
+          data: {
+            taskId: task.id,
+            documentId: doc.id,
+            status: 'failed',
+            errorMessage: error.message,
+          },
+        });
+        
+        await prisma.batchTask.update({
+          where: { id: taskId },
+          data: { failedCount: { increment: 1 } },
+        });
+      }
+    }));
+  }
+  
+  // 3.4 任务完成
+  await prisma.batchTask.update({
+    where: { id: taskId },
+    data: {
+      status: 'completed',
+      completedAt: new Date(),
+      durationSeconds: Math.floor((Date.now() - task.startedAt) / 1000),
+    },
+  });
+}
+
+// 4. 前端：查看批处理结果
+GET /api/v1/batch-tasks/:id/results
+返回：
+{
+  task: { /* 任务信息 */ },
+  results: [
+    {
+      documentId: 'xxx',
+      filename: 'paper1.pdf',
+      status: 'success',
+      data: {
+        研究设计: '随机对照试验',

+## 🎯 迁移关键点
+
+### 1. PKB模块迁移
+```
+✅ 简单：
+  - 数据库已在pkb_schema，无需迁移
+  - API端点清晰，易于复制
+  - 业务逻辑独立
+
+⚠️ 注意：
+  - Dify集成需要保持
+  - OSS文件上传需要保持
+  - 配额管理需要保持
+```
+
+### 2. AIA模块中的PKB集成迁移
+```
+✅ 简单：
+  - 接口清晰（fullTextDocumentIds/documentIds）
+  - 三种模式逻辑独立
+
+⚠️ 注意：
+  - chatController.ts需要同时迁移
+  - 前端3个模式组件需要迁移
+  - 对话历史管理需要保持
+```
+
+### 3. 测试要点
+```
+必须测试：
+  ✅ PKB CRUD功能
+  ✅ 文档上传和提取
+  ✅ RAG检索功能
+  ✅ 全文阅读模式（7篇文献）
+  ✅ 逐篇精读模式（文档切换）
+  ✅ 批处理模式（并发处理）
+  ✅ 配额管理
+  ✅ 对话历史管理
+  ✅ 模型切换

+### 4. 入口文件
+```
+src/modules/pkb/
+└─ index.ts  - 模块导出入口（新创建）
+```
+
+---
+
+## 🔧 已修复的导入路径
+
+### 修改前（legacy位置）
+```typescript
+import { prisma } from '../../config/database.js';
+import { difyClient } from '../../common/rag/DifyClient.js';
+import { LLMFactory } from '../../common/llm/adapters/LLMFactory.js';
+```
+
+### 修改后（modules/pkb位置）
+```typescript
+import { prisma } from '../../../config/database.js';
+import { difyClient } from '../../../common/rag/DifyClient.js';
+import { LLMFactory } from '../../../common/llm/adapters/LLMFactory.js';
+```
+
+### 关键修复
+- ✅ prisma路径：`../../../config/database.js`
+- ✅ difyClient路径：`../../../common/rag/DifyClient.js`  
+- ✅ extractionClient路径：`../../../common/document/ExtractionClient.js`
+- ✅ LLMFactory路径：`../../../common/llm/adapters/LLMFactory.js`
+- ✅ templates路径：`../../../legacy/templates/clinicalResearch.js`
+- ✅ batchRoutes改为default export
+
+---
+
+## ✅ 验证结果
+
+### 1. 文件完整性验证
+```bash
+✅ 所有文件已成功复制（9个文件）
+✅ 旧文件仍然存在（Test-Path返回True）
+✅ 新旧代码完全独立，互不影响
+```
+
+### 2. 目录结构验证
+```
+D:\MyCursor\AIclinicalresearch\backend\src\modules\pkb
+├───controllers/
+│   ├─ batchController.ts
+│   ├─ documentController.ts
+│   └─ knowledgeBaseController.ts
+├───routes/
+│   ├─ batchRoutes.ts
+│   ├─ knowledgeBases.ts
+│   └─ index.ts
+├───services/
+│   ├─ batchService.ts
+│   ├─ documentService.ts
+│   ├─ knowledgeBaseService.ts
+│   └─ tokenService.ts
+├───types/
+├───utils/
+└─ index.ts
+```
+
+### 3. 编译状态
+```bash
+⚠️ 有少量TypeScript类型错误（非致命）：
+   - 'any' type warnings（已存在于旧代码）
+   - 可以在后续优化中修复
+✅ 无新增的严重编译错误
+✅ 导入路径全部正确
+```
+
+---
+
+## 🔒 安全措施
+
+### 1. 旧代码完全保留
+```bash
+✅ src/legacy/controllers/ - 未修改
+✅ src/legacy/services/   - 未修改
+✅ src/legacy/routes/     - 未修改
+```
+
+### 2. 回滚方案（<1分钟）
+```bash
+# 如果新代码有问题，直接删除新目录即可
+rm -rf src/modules/pkb
+# 旧代码继续100%工作
+```
+
+### 3. 双轨并行
+```bash
+✅ 旧路由：/api/v1/knowledge/* - 继续工作
+🆕 新路由：准备就绪，待下一阶段注册
+```

+
+### 路由前缀结构
+
+```
+/api/v1/ (旧版本 - Legacy)
+├─ knowledge-bases (知识库CRUD)
+├─ documents (文档管理)
+└─ batch (批处理)
+
+/api/v2/pkb/ (新版本 - Modules架构)
+├─ health (健康检查) ← 新增
+├─ knowledge/
+│  ├─ knowledge-bases (知识库CRUD)
+│  └─ documents (文档管理)
+└─ batch-tasks/ (批处理)
+```
+
+---
+
+## 🛡️ 安全保障
+
+### 1. 零影响原则
+```bash
+✅ 旧路由完全未修改
+✅ 旧代码继续使用 legacy 路由
+✅ 现有用户和前端不受影响
+```
+
+### 2. 独立运行
+```bash
+✅ 新旧路由使用相同的数据库（pkb_schema）
+✅ 新旧路由使用相同的Service层
+✅ 数据100%一致
+```
+
+### 3. 灰度切换能力
+```bash
+✅ 前端可以选择使用v1或v2
+✅ 可以按用户分组切换
+✅ 可以随时回滚到v1
+```
+
+---
+

+
+## 🔧 技术实现亮点
+
+### 1. Ant Design X Chat集成
+```typescript
+// 复用通用能力层的Chat组件
+import { ChatContainer } from '@/shared/components/Chat';
+
+// 支持不同conversationType
+conversationType="pkb"
+
+// 自定义requestFn对接后端API
+providerConfig={{
+  requestFn: async (message: string) => {
+    // 根据工作模式传递不同参数
+    const response = await fetch('/api/v1/chat/stream', {
+      body: JSON.stringify({
+        fullTextDocumentIds,  // 全文阅读
+        documentIds,          // 逐篇精读
+      }),
+    });
+  },
+}}
+```
+
+### 2. 工作模式状态管理
+```typescript
+// 自定义Hook管理工作模式
+const {
+  workMode,              // 当前模式
+  selectedDocuments,     // 选中的文档
+  selectedTemplate,      // 选中的模板
+  setWorkMode,
+  setSelectedDocuments,
+  setSelectedTemplate,
+} = useWorkMode('full_text');
+```
+
+### 3. 路由设计
+```typescript
+// 模块内路由
+<Routes>
+  <Route path="/" element={<Navigate to="dashboard" />} />
+  <Route path="dashboard" element={<DashboardPage />} />
+  <Route path="workspace/:kbId" element={<WorkspacePage />} />
+</Routes>
+
+// 实际访问路径
+/knowledge-base/dashboard
+/knowledge-base/workspace/kb123
+```
+
+### 4. MinerU解析状态展示
+```typescript
+const getStatusBadge = (status: string) => {
+  const statusMap = {
+    completed: { text: '解析完成', color: 'green', icon: <CheckCircle2 /> },
+    uploading: { text: 'MinerU 版面分析', color: 'blue', icon: <Loader2 animate-spin /> },
+    parsing: { text: '结构化提取', color: 'purple', icon: <Loader2 animate-spin /> },
+    indexing: { text: '向量索引', color: 'orange', icon: <Loader2 animate-spin /> },
+    error: { text: '解析失败', color: 'red' },
+  };
+  // ...
+};

+
+## 🎯 三种工作模式实现
+
+### 1️⃣ 全文阅读模式（Full-text Reading）
+**适用场景**: 文献综述、横向对比  
+**核心机制**:
+```typescript
+// 加载全部文档ID
+const fullTextDocumentIds = documents
+  .filter(doc => doc.status === 'completed')
+  .map(doc => doc.id);
+
+// 传递给AI
+body: JSON.stringify({
+  content: message,
+  knowledgeBaseIds: [kbId],
+  fullTextDocumentIds,  // 🌟 全知视角
+})
+```
+
+**UI特性**:
+- ✅ 显示Token使用率（Progress圆形）
+- ✅ 全局视角提示："已加载 X 篇文档全文"
+- ✅ 默认欢迎消息引导
+
+### 2️⃣ 逐篇精读模式（Deep Reading）
+**适用场景**: 单篇文献详细分析  
+**核心机制**:
+```typescript
+// 用户手动选择1-5篇
+<Select
+  mode="multiple"
+  maxCount={5}
+  value={selectedDocs}
+  onChange={handleDocumentChange}
+/>
+
+// 传递给AI
+body: JSON.stringify({
+  content: message,
+  knowledgeBaseIds: [kbId],
+  documentIds: selectedDocuments,  // 🌟 限定范围
+})
+```
+
+**UI特性**:
+- ✅ 空状态提示
+- ✅ 选中状态Alert："已选择 X 篇文档"
+- ✅ 最多选5篇限制
+
+### 3️⃣ 批处理模式（Batch Processing）
+**适用场景**: 数据提取、表格生成  
+**核心机制**:
+```typescript
+// 选择批处理模板
+<Select
+  value={selectedTemplate}
+  onChange={handleTemplateChange}
+  options={[
+    { label: '临床研究信息提取', value: 'clinical_research' },
+    { label: '药物安全性分析', value: 'drug_safety' },
+  ]}
+/>
+
+// 执行批处理
+const response = await fetch('/api/v2/pkb/batch-tasks/batch/execute', {
+  method: 'POST',
+  body: JSON.stringify({
+    kb_id: kbId,
+    template_id: template,
+  }),
+});
+```
+
+**UI特性**:
+- ✅ 模板选择下拉框
+- ✅ 执行进度条（Progress）
+- ✅ 结果表格展示（Table）
+- ✅ Excel导出按钮
+
+---
+
+## 📊 代码质量
+
+### Linter检查
+- ✅ **0 Errors**
+- ✅ **0 Warnings**（已清理所有未使用的imports和变量）
+
+### TypeScript类型安全
+- ✅ 完整的类型定义（`workspace.ts`）
+- ✅ 所有API调用都有类型注解
+- ✅ Props类型严格
+
+### 代码规范
+- ✅ 遵循React函数组件规范
+- ✅ 使用React Hooks（useState, useEffect, useCallback）
+- ✅ 组件拆分合理
+- ✅ 注释清晰
+
+---
+
+## 🚀 下一步计划
+
+### 立即验证
+1. 启动frontend-v2开发服务器
+2. 访问Dashboard页面
+3. 测试创建知识库流程
+4. 测试Workspace页面
+5. 测试3种工作模式
+
+### 后续优化
+1. 添加文件上传功能（连接MinerU）
+2. 实现批处理结果轮询
+3. 添加PDF预览真实内容
+4. 优化响应式布局
+5. 添加单元测试
+
+---
+
+## 💡 关键设计决策记录
+
+### 决策1：为何不迁移旧代码？
+**原因**:
+- 新设计（V5.0）与旧代码UI/UX差异巨大
+- 旧代码基于旧架构，迁移成本高
+- 直接实现新设计可确保100%遵循PRD
+
+**优势**:
+- ✅ 设计一致性强
+- ✅ 代码更清晰
+- ✅ 避免技术债务
+
+### 决策2：工作模式如何集成？
+**方案选择**: 方案A - 智能问答Tab内嵌模式切换器
+
+**原因**:
+- 用户体验流畅（Collapse可折叠）
+- 三种模式共享Chat界面
+- 符合V3设计的Tab结构
+
+**实现**:
+```
+智能问答Tab
+├── 工作模式选择器（Collapse）
+│   ├── 全文阅读 [Radio]
+│   ├── 逐篇精读 [Radio + Select]
+│   └── 批处理 [Radio + Select]
+└── 模式内容区
+    ├── FullTextMode (Ant Design X Chat)
+    ├── DeepReadMode (Ant Design X Chat)
+    └── BatchMode (Progress + Table)
+```
+
+### 决策3：如何复用Ant Design X Chat组件？
+**策略**:
+- 使用`@/shared/components/Chat/ChatContainer`
+- 通过`conversationType="pkb"`区分会话类型
+- 通过`providerConfig.requestFn`自定义API调用
+- 通过不同参数（`fullTextDocumentIds` vs `documentIds`）实现模式差异
+
+---
