+
+## 🛡️ 安全机制
+
+### 安全检查
+
+- **恶意代码检测**：扫描 eval、exec、system 等危险函数
+- **硬编码密钥检测**：识别 API 密钥、密码等敏感信息
+- **SQL 注入检测**：检查可能的 SQL 注入漏洞
+- **XSS 检测**：识别跨站脚本攻击风险
+- **路径遍历检测**：检查文件路径操作安全性
+
+### 风险评估
+
+- **操作风险分级**：低、中、高、严重四个级别
+- **影响范围评估**：评估修复对系统的影响
+- **成功概率预测**：基于历史数据预测修复成功率
+- **回滚可行性**：确保修复失败时能够安全回滚
+
+### 合规验证
+
+- **Dockerfile 最佳实践**：避免使用 root、使用具体版本等
+- **依赖安全检查**：检查已知漏洞和推荐版本
+- **代码安全规范**：输入验证、错误处理等
+
+## 🔄 工作流程
+
+### 修复循环流程
+
+```
+监控触发 → 错误分析 → 策略生成 → 安全验证 → 
+自动备份 → 执行修复 → 触发构建 → 状态验证 → 
+成功确认 / 失败回滚 → 循环判断
+```
+
+### 状态转换图
+
+```
+IDLE → MONITORING → ANALYZING → REPAIRING → VERIFYING → COMPLETED
+                ↓           ↓         ↓         ↓
+             PAUSED     ROLLING_BACK  FAILED   IDLE
+```
+
+## 📊 监控和指标
+
+### 关键指标
+
+- **修复成功率**：成功修复次数 / 总修复尝试次数
+- **平均修复时间**：从检测到完成修复的平均时间
+- **回滚次数**：修复失败后的回滚操作次数
+- **安全违规次数**：被安全检查阻止的修复尝试
+- **系统可用性**：Space 处于正常运行状态的时间比例

+## 🔧 配置选项
+
+### 系统配置
+
+```python
+# config.py
+class RepairSystemConfig:
+    # 循环控制
+    max_repair_attempts: int = 5
+    loop_timeout_minutes: int = 60
+    retry_delay_seconds: int = 300

+    
+    # 备份设置
+    backup_before_repair: bool = True
+    backup_retention_days: int = 30
+    
+    # 通知设置
+    enable_notifications: bool = True
+    notification_channels: List[str] = ["email", "slack"]
+```
+
+### 环境变量
+
+```bash
+# HuggingFace API 配置
+export HF_TOKEN="your_hf_token"
+export HF_API_BASE_URL="https://huggingface.co/api"
+
+# 系统配置
+export HF_REPAIR_MAX_ATTEMPTS="5"
+export HF_REPAIR_TIMEOUT="3600"
+export HF_REPAIR_LOG_LEVEL="INFO"

+export HF_REPAIR_RETENTION_DAYS="30"
+```
+
+## 🚨 故障排除
+
+### 常见问题
+
+**Q: 修复循环卡在某个状态**
+```bash
+# 检查系统状态
+python -c "
+from integration_orchestrator import RepairOrchestrator
+orchestrator = RepairOrchestrator(None)
+print(orchestrator.get_active_workflows())
+"
+
+# 强制停止
+await orchestrator.stop_monitoring()
+```
+
+**Q: 安全检查过于严格**
+```python
+# 调整安全级别
+validator = SafetyValidator()
+# 临时调整风险阈值
+strategy.risk_level = "medium"  # 降低到可接受级别
+```
+
+**Q: 备份失败**
+```bash
+# 检查磁盘空间
+df -h
+
+# 检查权限
+ls -la /path/to/backups
+
+# 清理旧备份
+await rollback_manager.cleanup_old_backups(days=7)
+```
+
+### 日志分析
+
+```bash
+# 查看系统日志
+tail -f /var/log/hf-repair.log
+
+# 查看特定 Space 的修复历史
+grep "user/space" /var/log/hf-repair.log | tail -20
+
+# 分析错误模式
+grep "ERROR" /var/log/hf-repair.log | awk '{print $4}' | sort | uniq -c
+```
+
+## 📈 性能优化
+
+### 建议配置
+
+- **并发修复**：根据系统资源调整 `max_concurrent_repairs`
+- **缓存策略**：启用修复策略和错误模式的缓存
+- **批处理操作**：批量处理多个类似的修复请求
+- **资源监控**：监控系统资源使用情况
+
+### 扩展性
+
+- **水平扩展**：支持多实例部署
+- **插件架构**：支持自定义修复策略和安全检查器
+- **API 接口**：提供 REST API 进行远程管理
+- **事件驱动**：支持外部系统集成
