+- [x] 共用工具栏、列配置和图标操作
+- [x] 三个列表接入筛选、排序与列显隐
+- [x] 必需的服务端排序支持

+
+## Comments
+用户已授权开发；保留上一轮组合/参数组件改动。
+
+
+## 验收结果
+2026-09-12 本地实现完成：三个主列表使用共用筛选/列设置/排序工具栏，常用动作图标化；列选择保存在各自 localStorage 键。数据准备按名称、创建时间、更新时间在服务端排序，默认更新时间降序；在线字段排序保留禁用说明。
+
+验证：后端目录/数据准备/参数元数据相关 38 项测试通过，ruff 通过；前端构建通过。目录与参数组件共 8 个浏览器用例已通过（首轮 6 项通过，修正复选框测试定位和新建图标无障碍名称后，失败的 2 项分别复测通过）；新增组合筛选嵌套交互也通过。检查了桌面筛选/排序截图，已有用例验证 40px 行高、截断、窄屏底栏、跨页选择和在线查询约束。测试使用隔离模拟平台，未访问真实 WQ；构建仍提示已有依赖 eval 与大包体积警告。

+# 统一目录表格交互
+
+用户要求数据目录、字段目录、数据准备的表格交互与 Alpha 管理一致。统一筛选浮层（草稿/查询应用/重置）、列显隐持久化、独立排序浮层与左右工具栏；常用动作图标化，保留 aria-label 与提示。保留已完成的组合组件；不新增未授权的保存视图、导出或上游排序能力。服务端分页保持全量排序，在线字段仍需明确条件并点击查询，切换范围清空结果/勾选。
+
+本地验证覆盖筛选生效时机、排序跨页、列配置刷新恢复、图标名称、40px 行高和窄屏布局。保留前一任务全部改动。

+- [x] 补齐设置选项元数据与测试

+
+## Comments
+用户已批准方案，本轮开始实现；不修改旧项目。
+
+实现完成（2026-09-12）。新增共享选项模型、ScopePicker、SimulationSettingsEditor；目录通过 ScopeControls 兼容入口复用，三个回测入口使用同一编辑器。补齐服务端字段 choices/数值范围及 Delay/Universe 依赖解析，保留快照兼容。移除隐式 JSON 覆盖，历史 JSON 逐项校验且不覆盖原文。
+
+验证：后端相关 60 项通过；ruff check app tests 通过；前端 build（含类型检查）通过。前端相关 12 项验收通过（backtests 3、dataset 3、research-flows 1、research-outcomes 1、settings 4）；最后的选项过滤及收起态提示变更另复跑 settings 4 项通过。已查看桌面/390px 参数截图和集合内嵌选择面板截图。测试使用隔离数据库与模拟上游，没有访问真实 WorldQuant 或部署。构建保留既有 lottie eval 与包体积警告。

+# 通用组合与回测参数组件

+用户已确认开发。组合采用左摘要、右选择按钮，展开后以临时值编辑，应用时原子提交；取消不影响调用方。保留平台、本地与固定输入三种范围语义。回测表单复用组合选择；有 choices 的字段使用下拉，范围数值使用数字输入。参数选项与联动校验集中维护，历史非法值可见但不可预览。移除共用参数 JSON 隐式覆盖，保留独立候选 JSON 模式及服务端校验。
