+## 2026-05-15：恢复前端工作台交互质量
+
+- 前端工作台布局重新对齐旧版 `54773f547f6fcb853d73785f05ff5ac39ab2e5f5` 的信息架构：左侧导航、顶部标题栏、紧凑后台式内容区，导航项使用“数据上传 / 处理历史 / 数据管理 / 脚本编辑 / 系统设置”。
+- `ScriptPanel.vue` 不再使用普通 textarea，改为 `monaco-editor` SQL 编辑器，保留脚本读取、保存、执行和状态轮询接口；支持 SQL 高亮、行号、缩略图、光标行列状态和未保存状态。
+- Monaco 通过 Vue 异步组件按需加载，避免脚本编辑器依赖进入首屏主包；Vite worker 类型由 `frontend/src/vite-env.d.ts` 提供。
+- `SettingsPanel.vue` 的字段提取配置恢复为结构化树状配置：字段名、字段类型、提取来源列表、搜索、增删和去重保存，不再要求用户直接编辑 JSON。
+- 新增前端运行依赖 `monaco-editor`，构建时仍会生成 `frontend/dist/`，该目录继续作为构建产物忽略，不进入版本库。
+
 ## 2026-05-15：修复 Windows 启动脚本编码问题
 
 - `run.bat` 改为纯 ASCII 输出，并规范为 CRLF 行尾，避免 Windows `cmd` 在 PowerShell 中执行 UTF-8 中文批处理时把提示文本解析成碎片命令。
