+# 通道组编辑交互优化方案
+
+日期：2026-09-05。适用通道组新建与修改，用户已授权实施、提交推送及双环境发布。沿用TC-ADMIN-004路由语义，不改变真实通道价格、发送或计费规则。
+
+- 修正历史任意合法整数优先级回显；重复通道、归一化后重复省份及全国重复优先级明确报错，绝不删除或覆盖原行。弹窗确认只更新草稿。
+- 全国顺序支持上移、下移和拖拽；移动仅交换已有优先级槽位（如10/20），保留数值集合；新增通道建议下一个空闲优先级。提供明确顺序预览及撤销最近一次排序。
+- 通道选择支持名称/编号/地区搜索，展示成本及真实连接状态，禁用项说明原因；活动但暂时断连的通道仍可配置，保留历史停用通道且不误称连接正常。
+- 保存前展示新增、删除、调整以及基础设置变更摘要；未保存离开、刷新或后退需提示；失败保留输入，新建第二步失败保存已创建ID以便重试。请求沿用真实API，已有组status/description和成员weight/isBackup保持，不改数据模型。
+- 验收：纯函数冲突/排序/摘要测试，组件交互及前端回归、TypeScript、生产构建、CSS门禁；真实API的三尺寸浏览器查询、选择、排序、撤销及退出。禁止在验收中保存既有真实通道组或发送短信。
+- 发布：测试先行；预生产已确认发布完整最新版本，包含尚未发布的WPS异步解析、1项兼容migration及新解析Worker。独立恢复点与存储保护核验后再切换，不执行会改写无关配置的全量初始化脚本。

 - 运营端右上角新增“签名导入待审”，按签名导入资料中 pending_review 的明细条数计入待审核总数，独立于正式签名待审；点击进入签名审核的导入页签。统计遵守批次tenantId范围，invalid/approved/rejected明细不计入；导入提交及审核成功后立即刷新，不预先改计数。
 - 短信通道组新建/编辑的省网、全国列表展示成本价格（元/条），使用通道现有unitPrice及10000单位/元换算，保留4位小数；零成本显示0.0000，缺失通道/价格显示“—”。本次不改变通道选择、路由优先级和保存行为。
+
+### 2026-09-05 通道组编辑交互优化
+
+- 新建和修改通道组均使用草稿编辑：添加、编辑、删除、排序只改变当前页面草稿，最终确认保存时才调用真实接口。保存前展示基础设置、成员新增/删除和顺序调整摘要；保存失败保留输入。新建时若组已创建但成员保存失败，重试不得重复创建通道组。
+- 全国通道支持上移、下移和拖拽，移动时交换已有合法优先级槽位并保留历史优先级集合；支持撤销最近一次排序。历史任意 PostgreSQL `integer` 范围内优先级均可回显和编辑，新增项使用下一个未占用优先级。
+- 重复通道、归一化后重复省份及全国重复优先级必须明确阻止，不得静默覆盖已有成员。保存时保留已有组的状态、描述以及成员权重和主备属性。
+- 通道选择支持按名称、编号和地区搜索，直接展示成本价格、适用地区、运营商和真实连接回写。已删除、运营商不匹配、地区不匹配或已在本组配置的通道不可选择并说明原因；活动但暂时断连的通道允许配置。
+- 页面加载失败时禁止编辑和保存；存在未保存修改时，返回、路由切换、浏览器后退或刷新须提示。桌面、常用笔记本和 390px 窄屏均应可完成上述交互，且不得产生页面级横向溢出。

 - 后续交互建议（未实施）：现有历史优先级10/20与编辑下拉1—5不兼容；同优先级/同省份会过滤原行。建议先修正历史值回显和冲突处理，再加入全国路由上下移动/拖拽、明确顺序预览、可搜索通道选择及未保存提示；与本次成本展示分开实施。

+- 按用户确认方案完成通道组新建/修改交互：草稿编辑、历史优先级兼容、显式冲突校验、全国通道上移/下移/拖拽与撤销、顺序预览、可搜索通道选择、成本/地区/运营商/真实连接回写、不可选原因、保存摘要和未保存离开保护。保存继续使用真实API，保留既有组状态/描述及成员权重/主备属性；新建部分失败后以已创建ID重试，避免重复创建。
+- 新增页面及弹窗私有CSS，由各自TSX直接导入并登记所有权；未重建global.css、未向14个历史兼容模块追加规则、未增加`!important`或宽泛标签选择器，也未改变domains/index.css顺序。
+- 自动验证：通道组纯函数、选择弹窗和整页交互定向3套24项通过；前端全量17套90项、API全量55套620项通过。format:check、Stylelint、CSS治理15项、TypeScript/Vite生产构建、API构建、安全、部署契约和包体积门禁通过；既有Chart包体提示不影响构建。
+- 候选页面通过测试环境真实API/PostgreSQL只读验收，所有业务写请求由浏览器路由拦截。1600×1000、1366×768、390×844均完成排序/撤销、重复优先级拦截、搜索空态、保存前预览和离开取消；无页面级横向溢出，pageerror和console error为0。验收未保存真实通道组、未修改成本或通道配置、未发送/补发/重投/重新入队短信。
+- 测试与预生产发布前已分别建立独立恢复点并核验运行版本、服务、数据库迁移及存储保护。预生产从旧版本发布完整最新版本，预计新增1项向后兼容报备解析迁移及独立解析Worker；实际提交、推送、双环境切换和发布后真实验收结果在完成后追加。
