 ## 当前未完成项
 
-### 待前端修正 (前端 UI Agent 负责)
-
-- [ ] **资产中心弹窗主按钮禁用态过浅**
-  归属：`前端负责`
-  说明：资产中心内一批浅色弹窗底部的主按钮，在不可提交或 loading 前后状态下，存在“底色发灰、文字发白、和浅色 footer 混在一起”的问题，主次层级不清晰。请统一修正 `filled` 主按钮在浅色主题下的默认态 / disabled 态 / loading 态对比度，不要只改单个弹窗。
-  涉及位置：
-  `资产族弹窗`：`创建` / `保存修改`
-  `规格款弹窗`：`创建规格款` / `保存修改`
-  `CAD 导入弹窗`：`开始导入` / `继续导入`
-  `新增/编辑连接角色弹窗`：`新增` / `保存`
-  `基础资料库` 页面弹窗：`创建基材` / `保存修改` / `创建分类` / `创建饰面`
-
-- [ ] **资产中心弹窗次级文字按钮在浅底上过淡**
-  归属：`前端负责`
-  说明：浅色弹窗 footer 内的 `plain` 次级按钮，现在默认文字和背景层级太接近，小字号时尤其不清楚。请统一检查并修正 `plain` 按钮在浅色弹窗中的默认态、hover 态、禁用态，让“取消 / 完成 / 新增连接角色”这类按钮肉眼一看就能分清。
-  涉及位置：
-  `资产族弹窗`：`取消`
-  `规格款弹窗`：`取消`
-  `CAD 导入弹窗`：`取消` / `完成`
-  `连接角色区域`：`新增连接角色`
-  `新增/编辑连接角色弹窗`：`取消`
-  `基础资料库` 页：`新建分类`
-  `基础资料库` 页面弹窗：`取消`
-
-- [ ] **资产中心列表内图标按钮默认态辨识度不足**
-  归属：`前端负责`
-  说明：列表和卡片内的编辑 / 删除图标按钮，默认态颜色过浅，未 hover 时像“没激活”或“不可点”，尤其在浅色卡片和浅色分组背景里不够清楚。请统一调整这类圆形图标按钮的默认态和 hover 态，不要只修某一个图标。
-  涉及位置：
-  `资产族 / 规格款列表`：铅笔编辑按钮
-  `连接角色列表`：编辑 / 删除图标按钮
-  `基础资料库` 页：基材 / 分类 / 饰面列表的编辑 / 删除图标按钮
-
-- [ ] **同一弹窗内主次按钮层级需要统一规范**
-  归属：`前端负责`
-  说明：当前资产中心多个弹窗里，主按钮、次按钮、危险按钮的视觉层级不完全一致；有的主按钮太淡，有的删除按钮太抢，有的次按钮像禁用态。请按统一视觉标准整理这三类按钮在浅色主题弹窗 footer 内的层级关系，保证“主操作最清楚、次操作清楚但不抢、危险操作醒目但不刺眼”。这一项是规则统一，不是逐页补丁。
-
-- [ ] **基础资料库页面需要做正式视觉收口**
-  归属：`前端负责`
-  说明：`基础资料库` 已经作为独立子页面接入主流程，但目前还是功能先行版。请按全局统一视觉，把这个页面的左侧说明区、右侧列表区、分类筛选 chips、列表空态和“返回资产中心 / 新建分类 / 新建饰面 / 新建基材”几组操作做成和主线一致的正式界面，不要回退为老式后台页。
-
 ### 待联调确认 (全栈 / 后端 Agent 负责)
 
 - [ ] **资产中心资产族新流程人工验收**
   归属：`联调确认`
-  说明：确认资产中心现在已改成“先建资产族，再在资产族内新建规格款 / 发起 CAD 导入；缺资料时跳转基础资料库补录”的结构，用户理解是否自然，弹窗开关、列表刷新、导入完成后的落点是否符合预期。
