-## 多 Agent 协同
-
-本项目采用 4 Agent 协同模式。详见 `docs/AGENTS.md`。
-
-| Agent | 所有权 | 上下文文件 |
-|---|---|---|
-| 🗄️ DBA (数据库) | `src/db/`, `alembic/`, 数据模型 | `docs/agents/dba.md` |
-| 🖥️ FE (前端) | `frontend/` | `docs/agents/fe.md` |
-| ⚙️ BE (后端) | `src/api/`, `src/core/`, `src/llm/`, `src/data/` | `docs/agents/be.md` |
-| 🚀 Ops (部署) | `Dockerfile`, `docker-compose.yml`, 配置 | `docs/agents/ops.md` |
-
-## 技术栈
-
-- **后端**: Python 3.11+, FastAPI, SQLAlchemy async, PostgreSQL
-- **前端**: React, TypeScript, Vite, Tailwind CSS
-- **LLM**: OpenAI-compatible (OpenAI / Deepseek / Ollama)
-- **数据源**: bzzoiro, understat, api-football
-
-## 常用命令
-
-```bash
-# 后端
-uvicorn src.api.app:app --reload        # 启动 API
-pytest                                   # 测试
-alembic upgrade head                     # 数据库迁移
-
-# 前端
-cd frontend && npm run dev               # 开发
-cd frontend && npm run build             # 构建
-
-# 部署
-docker compose up -d                     # 启动全部服务
-```
-
-## 协作原则
-
-- 每个 Agent 在自己的所有权范围内工作
-- 跨 Agent 变更通过接口契约协调（REST API / ORM 模型 / docker-compose）
-- 修改接口前通知相关 Agent

+  0005 迁移在 predictions 表留下了 `cutoff_at` 列(删除语句被注释掉),
+  但 ORM 模型 `Prediction` 中并无该字段 —— 这是一处会长期存在的 schema 漂移,
+  而 alembic autogenerate 会持续建议 drop 它,造成噪声。
+
+  同时 0005 创建的两个索引 `ix_match_stats_available_at` 与
+  `ix_predictions_cutoff_at` 未在 ORM 声明,autogenerate 会建议删除它们 ——
+  一旦被误删,数据血缘相关的时间过滤查询会退化为全表扫描。
+
+本迁移做两件事:
+  1. drop 掉幽灵列 predictions.cutoff_at(数据已由 prediction_cutoff_at 承载,
+     迁移前先把非空值回填过去,避免丢数据)
+  2. 显式重建这两个索引(幂等:先 drop if exists 再 create),使 DB 状态与

-
-## 工作流程
-
-```
-1. 用户/编排者 发起任务
-2. 拆解任务分配给对应 Agent
-3. Agent 在各自所有权范围内工作
-4. 跨 Agent 变更通过接口契约协调
-5. 集成测试验证协作
-```

-## 变更协调规则
-
-| 变更类型 | 需要协调 |

-| 新增 API 字段 | BE + FE |
-| 修改数据模型 | DBA + BE + FE |
-| 新增数据源 | DBA + BE |
-| 修改部署配置 | Ops + 所有 |

-
-### LLM 预测管线
-```
-match_id → build_context (数据切片) → LLM 调用 → 解析 → 存储
-```
-
-### 多 Agent 编排 (LLM 专家系统)
-```
-5 专家 (form/stats/home_away/injuries/h2h) → 终裁 → 最终预测
-```
-
-### 数据源协议
-```python
-class DataSource(Protocol):
-    name: str
-    async def ingest(db, **kwargs) -> dict: ...
-```
-
-## 设计原则
-- RESTful API，OpenAPI 文档自动生成
-- 异步优先（asyncpg + async httpx）
-- 错误分层（404/502/500）
-- 预测结果持久化
-
-## 对外接口
-- 为 FE Agent 提供稳定 REST API
-- 使用 DBA Agent 提供的 ORM 模型
-- 遵循 Ops Agent 定义的环境配置

-## 设计原则
-- 所有字段可空性明确（业务可空 vs 必须 NOT NULL）
-- 外键级联删除合理（match 删除 → stats/predictions 级联）
-- 索引覆盖高频查询（按日期、按球队、按联赛）

-## 设计原则
-- 配置与代码分离（.env 不入库）
-- 健康检查（postgres + api）
-- 数据持久化（postgres volume）
-- 最小镜像（python:3.11-slim）
-
-## 对外接口
-- 为 BE Agent 提供运行环境

-## 不做
-- 不写应用代码
-- 不修改业务逻辑
-- 不变更 API 契约

+# 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。
+**与前台共用同一套「报刊风」设计语言**:纸色底(paper)、墨色字(ink)、印报红唯一强调(press),
+宋体标题、方正边框、细线分隔,无圆角、无彩色药丸标签。
+支持响应式布局(移动端 / 平板 / 桌面)。
+
+## 文件结构
+
+```
+src/admin/
+├── AdminApp.tsx          # Admin 应用入口(独立路由)
+├── AdminLayout.tsx       # 布局(报头式侧栏 + 报眉顶栏,健康状态每 60s 复检)
+├── api.ts                # 统一 API 客户端(超时、错误处理、X-API-Key 自动附带)
+├── 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 模型对齐)
+├── components.tsx        # 通用 UI 组件(报刊风 Card/Badge/DataTable/Alert...)
+├── 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,结果结构化展示)

+    ├── Backtest.tsx      # 回测管理(汇总指标 + 逐场明细 + 模型评估)

+```
+
+## 页面说明
+
+### 1. 仪表盘 (`/admin`)
+- 系统健康状态、联赛 / 比赛 / 预测数量统计(报纸数字版式)
+- 已入库联赛列表
+- 快捷操作导航
+
+### 2. 数据采集 (`/admin/collection`)
+- 选择数据源: Bzzoiro / Understat / Injuries
+- 选择联赛、日期范围(Understat 为赛季)
+- 触发采集任务;结果结构化展示(新增 / 更新 / 跳过 / 未匹配 / 错误)
+
+### 3. 预测管理 (`/admin/predictions`)
+- 触发预测(选择比赛 + 模式:多专家 / 单次)
+- **预测结算**: 录入实际比分,调用 /eval/settle,供准确率统计使用
+- 预测记录列表: 点击展开终裁理由与五路专家摘要
+
+### 4. 回测管理 (`/admin/backtest`)
+- 回测配置: 联赛(下拉)、日期范围、场数、模式
+- 结果汇总: 已评分 / 1X2 准确率 / 比分 RMSE / 平均置信度
+- 逐场明细: 实际比分 vs 预测比分,正误标记
+- 模型评估: 各模型历史准确率(/eval/summary)
+
+### 5. 监控面板 (`/admin/monitoring`)
+- /health 存活检查 + /health/ready 数据库就绪检查
+- 每 30 秒自动巡检,可手动「立即巡检」
+- 服务名 / 版本 / 运行时间 / 检查项
+
+### 6. 数据源管理 (`/admin/data-sources`)
+- 数据源状态: API Key 配置状态(脱敏)
+- 测试连接: 调用采集 API 验证
+- 数据源说明文档
+
+### 7. LLM 配置 (`/admin/llm-config`)
+- 当前配置: provider, model, base_url
+- 连接测试(会真实调用一次预测,产生 LLM 费用)
+- 使用统计: 预测次数、延迟、有效率(从预测记录聚合)
+- 可用模型列表
+
+### 8. 系统配置 (`/admin/config`)
+- **管理员密钥管理**: 保存 X-API-Key 到本机 localStorage,之后所有请求自动附带;
+  后端配置了 ADMIN_API_KEY 时,采集 / 回测 / 结算接口依赖此密钥
+- 配置列表: 脱敏显示 .env 配置项
+- 配置修改指南: SSH 修改 .env + 重启服务
+
+## 鉴权说明
+
+后端 `ADMIN_API_KEY` 的渐进式策略:
+- 未配置 → 写入型接口无鉴权(本地开发)
+- 已配置 → 采集 / 回测 / 结算接口必须带 `X-API-Key` 请求头
+
+前端在 `api.ts` 统一注入该请求头;密钥在「系统配置」页设置,
+仅存于本机浏览器 localStorage。401 错误会提示到该页填写密钥。
+
+## 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、结算与记录 |
+| `/admin/backtest` | 回测管理 | 策略回测 |
+| `/admin/monitoring` | 监控面板 | 系统监控 |
+| `/admin/data-sources` | 数据源管理 | 数据源配置 |
+| `/admin/llm-config` | LLM 配置 | 模型管理 |
+| `/admin/config` | 系统配置 | 密钥与参数配置 |
+
+## 响应式布局
+
+### 移动端 (< 768px)
+- 侧边栏折叠为汉堡菜单,点击展开
+- 表格隐藏,显示卡片视图
+- 表单单列布局;按钮最小 44px 触摸目标
+- 统计卡片 1 列
+
+### 桌面 (> 1024px)
+- 侧边栏固定显示;完整表格视图;统计卡片 4 列
+
+## 技术实现
+
+- **路由**: `react-router-dom` v6 嵌套路由
+- **样式**: Tailwind CSS,与前台共用 paper/ink/press 色板与组件类
+  (.btn / .field / .tab / .section-head / .skeleton 见 `src/index.css`)
+- **API**: 统一 fetch 客户端,30s 超时,类型安全,X-API-Key 自动附带
+- **类型**: TypeScript strict mode,与后端 Pydantic 模型对齐
+- **错误处理**: ApiError 类 + 页面级 Alert 展示
+- **触摸友好**: 所有可点元素 min-h-[44px]
+
+## 启动方式
+
+```bash
+cd 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 后台侧栏底部「返回前台版面」链接可回到 `/`。
