+# InsightFlow Phase 8 Task 5 - 运营与增长工具开发
+
+## 完成内容
+
+### 1. 创建 `growth_manager.py` - 运营与增长管理模块
+
+实现了完整的运营与增长工具模块，包含以下核心功能：
+
+#### 1.1 用户行为分析（Mixpanel/Amplitude 集成）
+- **事件追踪**: `track_event()` - 支持页面浏览、功能使用、转化漏斗等事件类型
+- **用户画像**: `UserProfile` 数据类 - 包含活跃度、留存率、LTV 等指标
+- **转化漏斗**: `create_funnel()`, `analyze_funnel()` - 创建和分析多步骤转化漏斗
+- **留存率计算**: `calculate_retention()` - 支持同期群留存分析
+- **实时仪表板**: `get_realtime_dashboard()` - 提供实时分析数据
+
+#### 1.2 A/B 测试框架
+- **实验管理**: 
+  - `create_experiment()` - 创建实验，支持多变体
+  - `start_experiment()`, `stop_experiment()` - 启动/停止实验
+  - `list_experiments()` - 列出所有实验
+- **流量分配**:
+  - 随机分配 (Random)
+  - 分层分配 (Stratified) - 基于用户属性
+  - 定向分配 (Targeted) - 基于目标受众条件
+- **结果分析**: `analyze_experiment()` - 计算统计显著性和提升幅度
+
+#### 1.3 邮件营销自动化
+- **邮件模板管理**:
+  - `create_email_template()` - 创建 HTML/文本模板
+  - `render_template()` - 渲染模板变量
+  - 支持多种类型：欢迎邮件、引导邮件、流失挽回等
+- **营销活动**: `create_email_campaign()` - 创建和管理批量邮件发送
+- **自动化工作流**: `create_automation_workflow()` - 基于触发器的自动化邮件序列
+
+#### 1.4 推荐系统
+- **推荐计划**:
+  - `create_referral_program()` - 创建邀请返利计划
+  - `generate_referral_code()` - 生成唯一推荐码
+  - `apply_referral_code()` - 应用推荐码追踪转化
+  - `get_referral_stats()` - 获取推荐统计数据
+- **团队升级激励**:
+  - `create_team_incentive()` - 创建团队规模激励
+  - `check_team_incentive_eligibility()` - 检查激励资格
+
+### 2. 更新 `schema.sql` - 添加数据库表
+
+添加了以下 13 张新表：
+
+1. **analytics_events** - 分析事件表
+2. **user_profiles** - 用户画像表
+3. **funnels** - 转化漏斗表
+4. **experiments** - A/B 测试实验表
+5. **experiment_assignments** - 实验分配记录表
+6. **experiment_metrics** - 实验指标记录表
+7. **email_templates** - 邮件模板表
+8. **email_campaigns** - 邮件营销活动表
+9. **email_logs** - 邮件发送记录表
+10. **automation_workflows** - 自动化工作流表
+11. **referral_programs** - 推荐计划表
+12. **referrals** - 推荐记录表
+13. **team_incentives** - 团队升级激励表
+
+以及相关的索引优化。
+
+### 3. 更新 `main.py` - 添加 API 端点
+
+添加了完整的 REST API 端点，包括：

+
+### 4. 创建 `test_phase8_task5.py` - 测试脚本
+
+完整的测试脚本，覆盖所有功能模块：
+- 24 个测试用例
+- 涵盖用户行为分析、A/B 测试、邮件营销、推荐系统
+- 测试通过率：100%
+
+## 技术实现特点
+
+1. **代码风格一致性**: 参考 `ai_manager.py` 和 `subscription_manager.py` 的代码风格
+2. **类型注解**: 使用 Python 类型注解提高代码可读性
+3. **异步支持**: 事件追踪和邮件发送支持异步操作
+4. **第三方集成**: 预留 Mixpanel、Amplitude、SendGrid 等集成接口
+5. **统计显著性**: A/B 测试结果包含置信区间和 p 值计算
+6. **流量分配策略**: 支持随机、分层、定向三种分配方式
+
+## 运行测试
+
+```bash
+cd /root/.openclaw/workspace/projects/insightflow/backend
+python3 test_phase8_task5.py
+```
