 - 容量数据和 CellData 卡片左上角均标注数据类型，右上角均有说明按钮；容量数据说明弹窗明确启用 CellData 时会在处理容量数据前先更新 CellData。
 - CellData 卡片点击后选择文件夹，拖拽也只接受文件夹；不支持单个 ZIP 文件直接拖入，避免缺少频段目录导致无法映射。
 - 验证：`frontend` `npm run build` 通过；构建产物已清理。

+## 2026-06-25：远程数据源页收纳 CellData 规则设置
+
+- 远程数据源页只保留容量数据源与 CellData 数据源两张连接配置卡片，宽屏下并排展示；CellData 的扫描路径、正则和映射 JSON 收纳到「规则设置」弹窗。
+- CellData 规则弹窗包含扫描路径列表、路径说明入口、高级正则和 Monaco JSON 编辑器，支持格式化、校验、恢复默认映射和保存规则。
+- 验证：`frontend` `npm run build` 通过；构建产物已清理。
