+# 学习信息后台接口 总设计
+
+> API-ADMIN-INFO-000 | v1.0 | 2026-06-09
+
+## 1. 概述
+
+基于 M8 核心数据表（ReadingEvent / LearningSession / MaterialReadingProgress / DailyLearningActivity / LearningRecord / TemporaryReadingMaterial），为 Admin Dashboard 提供管理查询、诊断、操作接口。
+
+### 路由前缀
+
+```
+/admin/learning/*
+```
+
+### 鉴权
+
+- 所有接口需要 `AdminJwtGuard`
+- 角色要求：`ADMIN` 或 `SUPER_ADMIN`
+- 审计日志记录操作人和时间
+
+## 2. 接口总览
+
+### 查询接口
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | `/admin/learning/dashboard` | Dashboard 概览 |
+| GET | `/admin/learning/reading-events` | ReadingEvent 列表/详情 |
+| GET | `/admin/learning/reading-events/:id` | ReadingEvent 详情 |
+| GET | `/admin/learning/reading-events/failed` | 失败/警告/重复事件 |
+| GET | `/admin/learning/sessions` | LearningSession 列表 |
+| GET | `/admin/learning/sessions/:id` | LearningSession 详情 |
+| GET | `/admin/learning/progress` | MaterialReadingProgress 列表 |
+| GET | `/admin/learning/progress/:id` | 资料进度详情 |

+
+### 操作接口
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| POST | `/admin/learning/reading-events/:id/reprocess` | 重处理单事件 |
+| POST | `/admin/learning/reading-events/reprocess-batch` | 批量重处理 |
+| POST | `/admin/learning/recalculate` | 重算学习数据 |
+| GET | `/admin/learning/export` | 导出学习数据 |
+| PUT | `/admin/learning/event-config` | 事件处理配置 |
+
+## 3. 分页/筛选/排序规范
+
+```typescript
+interface PaginationQuery {
+  page?: number;       // default 1
+  limit?: number;      // default 20, max 100
+  sortBy?: string;     // 排序字段
+  order?: 'asc' | 'desc';  // default desc
+}
+
+interface EventFilter extends PaginationQuery {
+  userId?: string;
+  materialId?: string;
+  readingTargetType?: string;
+  eventType?: string;
+  status?: string;
+  startDate?: string;
+  endDate?: string;
+}
+```
+
+## 4. Dashboard 数据结构
+
+```typescript
+interface AdminDashboard {
+  overview: {
+    totalEvents: number;
+    todayEvents: number;
+    failedEvents: number;
+    duplicateEvents: number;
+  };
+  sessions: {
+    active: number;
+    interrupted: number;
+    completed: number;
+    total: number;
+  };
+  users: {
+    activeToday: number;
+    totalWithEvents: number;
+  };
+  materials: {
+    totalRead: number;
+    totalMarkedRead: number;
+  };
+}
+```
+
+## 5. 审计日志
+
+每个管理操作记录：
+- `action`: 操作类型 (READ/WRITE/DELETE/EXPORT)
+- `resource`: 资源路径
+- `adminId`: 操作人
+- `timestamp`: 时间
+- `details`: 详情（查询参数/操作结果摘要）
+
+## 6. 错误码
+
+| 码 | 含义 |
+|----|------|
+| `ADMIN_ACCESS_DENIED` | 非管理员 |
+| `INVALID_DATE_RANGE` | 日期范围无效 |
+| `EXPORT_LIMIT_EXCEEDED` | 导出超限 |
+| `RECALCULATE_IN_PROGRESS` | 重算进行中 |
