+# Profeto Admin 后台管理系统
+
+## 概述
+
+Profeto 后台管理界面,为足球 LLM 预测系统提供运维管理能力。
+暗色主题设计,支持响应式布局。
+
+## 文件结构
+
+```
+src/admin/
+├── AdminApp.tsx          # Admin 应用入口(独立路由)
+├── AdminLayout.tsx       # 管理后台布局(侧边栏 + 顶栏 + 内容区)
+├── api.ts                # 统一 API 客户端(带超时、错误处理、类型安全)
+├── dal.ts                # 数据访问层(封装所有 API 端点调用)
+├── types.ts              # TypeScript 类型定义(与 FastAPI Pydantic 对齐)
+├── components.tsx        # 通用 UI 组件(Card, Table, Badge, ProgressBar...)
+├── routes.tsx            # 路由定义(/admin/*)
+└── pages/
+    ├── Dashboard.tsx     # 仪表盘(系统概览)
+    ├── Collection.tsx    # 数据采集(触发采集任务)
+    ├── Predictions.tsx   # 预测管理(触发预测 + 评估结算)
+    ├── Backtest.tsx      # 回测管理(策略验证)
+    ├── Monitoring.tsx    # 监控面板(健康检查 + 错误日志)
+    └── Config.tsx        # 配置管理(API Key 管理)
+```
+
+## 页面说明
+
+### 1. 仪表盘 (`/admin`)
+- 数据库表行数统计
+- 最近采集任务状态
+- 预测统计(总数、今日数、平均延迟)
+- 最近错误日志
+
+### 2. 数据采集 (`/admin/collection`)
+- 选择数据源: Bzzoiro / Understat / Injuries
+- 选择联赛、日期范围
+- 触发采集任务
+- 实时任务进度显示(每 5 秒自动刷新)
+
+### 3. 预测管理 (`/admin/predictions`)
+- 触发预测(全部联赛或指定联赛)
+- 模式切换: 五路专家 / 单一模型
+- 预测历史分页查看
+- 评估结算(回填实际结果)
+
+### 4. 回测管理 (`/admin/backtest`)
+- 策略选择: 置信度加权 / Kelly准则 / 固定金额
+- 联赛多选、日期范围、初始资金配置
+- 回测结果: ROI、胜率、最大回撤、夏普比率
+- 交易明细可展开查看
+
+### 5. 监控面板 (`/admin/monitoring`)
+- 系统健康状态(服务 + 检查项)
+- 错误日志(每 10 秒自动刷新)
+- 死信队列监控
+
+### 6. 配置管理 (`/admin/config`)
+- API Key 配置(LLM / 数据源 / 系统)
+- 脱敏显示 + 在线编辑
+
+## 路由设计
+
+| 路径 | 页面 | 描述 |
+|------|------|------|
+| `/` | 先知主站 | 报纸风格预测展示 |
+| `/admin` | 仪表盘 | 系统概览 |
+| `/admin/collection` | 数据采集 | 采集任务管理 |
+| `/admin/predictions` | 预测管理 | 预测与评估 |
+| `/admin/backtest` | 回测管理 | 策略回测 |
+| `/admin/monitoring` | 监控面板 | 系统监控 |
+| `/admin/config` | 配置管理 | 参数配置 |
+
+## 技术实现
+
+- **路由**: `react-router-dom` v6 嵌套路由
+- **样式**: Tailwind CSS 暗色主题 (gray-900/800/700)
+- **API**: 统一 fetch 客户端,30s 超时,类型安全
+- **类型**: TypeScript strict mode,与后端 Pydantic 模型对齐
+- **错误处理**: ApiError 类 + 页面级错误展示
+- **自动刷新**: 采集(5s)、监控(10s)
+
+## 启动方式
+
+```bash
+cd /vol2/1000/Docker/Profeto/frontend
+npm run dev
+# 访问 http://localhost:5173/admin
+```
+
+## 访问入口
+
+主站页面顶部「管理后台」链接可跳转至 `/admin`。
+Admin 后台左侧底栏「返回前台」链接可回到 `/`。
