+## 报销类型页面布局
+
+报销类型页面采用左侧搜索/选择类型、右侧编辑规则的分栏布局。类型列表和规则区域分别滚动，底部保存栏始终可见；保存成功显示反馈，继续修改后恢复保存提示。新增类型固定在左下方，重命名/删除集中在详情标题的更多菜单中。
+
+基本信息包含明确的说明和提示标签；上传材料逐行配置不使用/选填/必填，编辑与删除位于该行更多菜单。添加、编辑材料使用弹窗，保存材料时也保存当前类型规则。只读权限及删除确认保持不变。全局类型页面不显示无关的项目/组别筛选。
+
+保存规则只合并当前类型的服务端结果，不覆盖其他类型尚未保存的编辑。切换类型不会自动保存；刷新或退出前仍应主动保存。
+
+回归验证：`swiftc reimburse/AdminModels.swift reimburse/AdminStore.swift tests/AdminPolicyEditorTests.swift -o /tmp/admin-policy-editor-tests && /tmp/admin-policy-editor-tests`。
+
+## 报销类型管理
+
+“报销类型”页新增“类型管理”区域，可查看全部启用/停用类型。平台管理员可新增、重命名或确认删除，普通管理账号只读。新增名称限制 1–40 字且不可重名，默认停用；创建后在下方配置规则、勾选启用并保存。删除立即生效，不是停用；历史报销记录及附件保留，历史类型名称不随重命名改变。类型配置对所有项目生效。
+
+服务端拒绝时弹窗保留输入并显示错误；成功后更新列表和当前选择，不清空其他类型尚未保存的规则。需同步更新 Go 服务和微信小程序，无需为本功能修改数据库结构。
+
 ## 删除材料与不使用
 
 “报销类型”中的垃圾桶会确认后调用材料类型删除接口，立即从全局材料列表及所有报销类型的材料规则中删除该材料，不删除历史报销附件。即使材料已选“不使用”，也保留删除入口。删除失败不会在本机假装移除；成功后保留其他尚未保存的规则编辑。
