详细检查项目:
✓ DSL文件结构验证
✓ DSL语法正确性
✓ 节点连接完整性  
✓ 内容迁移完整性
✓ UI集成验证
✓ 配置文件验证
✓ 音频资源验证
✓ 角色定义验证
✓ 锚点系统验证
✓ 故事完整性验证

迁移成果:
- 原3700+行硬编码转换为模块化DSL
- 创建了8个故事模块文件
- 实现了完整的引擎适配器
- UI成功集成新引擎
- 保持了向后兼容性

技术架构:
- 新DSL引擎 + 适配器模式
- 响应式状态管理
- 懒加载 + 智能缓存
- 错误处理 + 优雅降级
- 性能监控 + 调试工具

结论: 
${if (passed.toFloat() / total >= 0.8f)
