+# 优化工作台图层与场景标线
+
+## Goal
+
+移除不再需要的高德规整路口参考图层，提供可读的编译概览，并恢复场景模式下双向道路中心线的可辨识渲染。
+
+## Confirmed Facts
+
+- 科技园一路的三个双向路段在 `center_lines.geojson` 中都有完整的黄色虚线 feature；不是编译缺失。
+- React adapter 将原版中心线的属性驱动样式简化为固定样式，造成场景模式下辨识度不正确。
+- 高德参考层仅在 React 前端图层 registry、图层开关和状态装载中使用；不影响编译。
+
+## Acceptance Criteria
+
+- 工作台不显示或加载高德规整路口参考图层。
+- 场景模式下保留中心线，并按线的颜色和虚/实线属性清晰渲染。
+- 编译概览以中文分组指标和诊断摘要展示，不显示 schema、note、null 或 `[object Object]`。
+- 格式化、类型检查和生产构建通过。
