+# 宇之然内容创作平台 - 项目完成报告
 
-## ✅ 前端页面与API打通验证
+## 📊 总体进度
+- 基础平台 (4月29日): ✅ 完成
+- 管理功能扩展 (5月1-2日): ✅ 完成
 
-| 页面 | 功能 | API端点 | 状态 | 说明 |
-|-----|------|---------|------|------|
-| topics.html | 加载选题 | GET /api/topics | ✅ | 已实现，需要认证 |
-| topics.html | 优化选题 | POST /api/optimizer/run | ✅ | 已实现 |
-| topics.html | 发布选题 | POST /api/publishing/create | ✅ | 已实现 |
-| topics.html | 删除选题 | DELETE /api/topics/{id} | ✅ | 已实现 |
-| logs.html | 加载日志 | GET /api/logs | ✅ | 已实现 |
-| users.html | 加载用户 | GET /api/admin/users | ✅ | 已实现，需要认证 |
-| users.html | 删除用户 | DELETE /api/admin/users/{id} | ✅ | 已实现 |
-| users.html | 新增用户 | POST /api/admin/users | ✅ | 已实现 |
+## ✅ 已实现功能
 
-*系统概览模块状态已改为动态展示，显示内容收集、内容创作、合规审查三模块（原发布管理器已移除）。*
+### 后端 API
+- 选题管理: GET/POST /api/topics, ... 
+- 用户管理: /api/admin/users
+- 案例管理: /api/admin/cases (CRUD)
+- 任务日志: /api/admin/tasklogs (CRUD)
+- LLM配置: /api/admin/llmconfigs (CRUD)
+- 系统配置: /api/admin/systemconfigs (CRUD, value自动JSON解析)
 
-## 🔧 后端API状态
+### 数据库与数据
+- 初始数据导入: 20选题 + 30案例
+- 自动创建管理员账号 (admin/admin123)
+- 默认LLM配置和系统配置
 
-### 路由注册 (app/main.py)
-- prefix="/api/topics" → topics.router ✅
-- prefix="/api/system" → system.router ✅
-- prefix="/api/publishing" → publishing.router ✅
-- prefix="/api/admin" → admin.router ✅
-- prefix="/api" → optimizer_logs.router ✅
-- prefix="/api/auth" → auth.router ✅
+### 前端界面
+- 系统管理页面: admin.html (标签页统一管理)
+- 导航菜单: 在 topics.html, logs.html, users.html 的侧边栏与移动导航中添加“系统管理”入口
+- 深色主题保持一致
 
-### 测试结果
-```
-系统状态: {'stats': {'total': 27, 'pending': 20, 'review': 2, 'ready': 4, 'published': 1, 'today': 0}}
-登录接口: {'code': 200, 'token_acquired': True}
-获取选题: {'code': 200, 'count': 27, 'sample': {'id': 'TOPIC-BBB1CC', 'title': '城市农业新趋势: 东京垂直农场：10平米 balcony 年产蔬菜 100kg与上海阳台种菜年省 3000 元：居民自种调查的中国落地路径', 'field': '可持续生活系统', 'priority_score': 25, 'status': '待发布', 'compliance_score': 100, 'ready_at': '2026-04-21', 'published_at': None, 'generated_at': None, 'platform_urls': {}, 'created_at': '2026-04-24T02:28:50', 'updated_at': '2026-04-25T10:54:33.578210'}}
-获取用户: {'code': 200, 'count': 3}
+## 🚀 启动方式
+```bash
+cd /root/openclaw-workspace/projects/yu-zhi-ran
+./start-platform.sh 8001
+# 或
+uvicorn app.main:app --port 8001
 ```
 
-## 🔐 认证机制
-- 登录页面: `/login.html`
-- 默认管理员账号: `admin` / `admin123`
-- Token存储: `localStorage.getItem('authToken')`
-- 认证方式: Bearer Token (JWT)
+默认管理员: admin / admin123
 
-## 📊 数据状态
-- 选题库 (sustainability_topics.json): 28个选题 (待处理22, 待发布4, 待审查2)
-- 数据库 (yzr.db): topics表24条记录, articles表0条
+## 📁 关键文件变更
+- `platform/backend/app/main.py`: 注册新路由
+- `platform/backend/app/api/`: 新增 cases.py, task_logs.py, llm_configs.py, system_configs.py
+- `platform/backend/app/schemas.py`: 新增 Case, TaskLog, LLMConfig, SystemConfig 的Schema
+- `automation/data/initial_cases.json`: 扩展至30条案例
+- `platform/frontend/`: 新增 admin.html, 更新导航链接（侧边栏+移动端）
 
-## 🎯 最终结论
-**前端与API已实现真实打通**，所有页面操作均可调用对应的后端端点。需要先登录获取token，然后即可正常使用管理功能。
+## ⚠️ 注意事项
+- 所有 AI 调用必须串行，频率不超过 30次/分钟
+- 使用 Bearer Token (JWT) 认证
