+# 招投标信息维护后端实施计划
+
+## 目标
+- 将现有 `purchaseTransaction` 后端链路改造为“招投标主信息 + 供应商明细子表”结构。
+- 保留原有 URL、权限前缀和内部类名，统一用户可见文案为“招投标信息维护”。
+- 支持详情查询返回全部供应商明细，列表返回中标供应商摘要和参与供应商数。
+- 支持双 Sheet 导入模板与按 `purchaseId` 聚合校验的异步导入。
+
+## 实施内容
+- 数据层
+  - 新增 `ccdi_purchase_transaction_supplier` 明细表初始化 SQL 与增量迁移脚本。
+  - 迁移脚本回填历史中标供应商数据，并将菜单名称更新为“招投标信息维护”。
+- 领域模型
+  - 新增供应商 entity、DTO、VO、Excel 模型。
+  - 主 DTO/VO 增加 `supplierList`，主 VO 增加 `supplierCount`。
+  - 主 Excel 模板改为仅承载招投标主信息，供应商明细独立建模。
+- 接口与服务
+  - 列表 SQL 增加供应商数聚合。
+  - 详情查询补充供应商明细列表。
+  - 新增/修改时由 `supplierList` 自动回填主表中标供应商摘要字段。
+  - 删除主记录时级联删除供应商明细。
+  - 导入链路改为“双 Sheet 读取 + 按事项聚合校验 + 主从同落库”。
+- 项目专项核查
+  - 项目采购详情 VO、Mapper、Service 增加供应商明细查询能力，保持项目详情与信息维护详情口径一致。
+
+## 验证
+- `mvn -pl ccdi-info-collection,ccdi-project -am -DskipTests compile`
+- `./bin/restart_java_backend.sh restart`
+- 浏览器验证列表接口、详情接口与项目详情供应商明细展示。

+# 招投标信息维护弹窗宽度与供应商序号前端实施计划
+
+## 保存路径确认
+- 前端实施计划保存到 `docs/plans/frontend/`
+
+## 目标
+- 新增、编辑弹窗宽度调整为页面宽度的 `80%`
+- 供应商明细不再录入排序，改为页面按当前行顺序自动生成序号与提交顺序
+
+## 实施范围
+- 文件：`ruoyi-ui/src/views/ccdiPurchaseTransaction/index.vue`
+
+## 实施步骤
+1. 将新增/编辑共用弹窗宽度从固定像素改为 `80%`
+2. 将供应商明细表中的“排序”输入列改为只读“序号”展示列
+3. 调整供应商新增与提交逻辑，提交时按当前行顺序自动补齐 `sortOrder`
+4. 清理空白供应商行判断，避免隐藏排序字段后把空白行误判为有效数据
+5. 使用真实页面验证新增/编辑弹窗显示与供应商录入行为
+
+## 验证点
+- 新增/编辑弹窗宽度明显放大至页面宽度的 `80%`
+- 供应商明细不再出现排序输入框
+- 新增供应商后可正常录入供应商名称、统一信用代码、联系人、联系电话、银行账户
+- 编辑已有数据时供应商顺序按当前表格行顺序提交

+- 详情展示
+  - 页面详情弹窗改为供应商明细表展示。
+  - 项目专项核查采购详情弹窗同步改为供应商明细表展示。

+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将招聘信息管理页“新增招聘信息”“修改招聘信息”共用弹窗的宽度从固定 `900px` 调整为页面宽度的 `80%`，提升表单内容展示空间。
+
+**Architecture:** 本次仅调整 `ccdiStaffRecruitment` 页面新增/编辑弹窗的 `el-dialog` 宽度配置，不新增字段、不改动详情弹窗、不调整提交逻辑和接口交互。
+
+**Tech Stack:** Vue 2, Element UI, JavaScript, Markdown

+## 文件结构与职责
+
+- `ruoyi-ui/src/views/ccdiStaffRecruitment/index.vue`

+  - 结果：
+    - 菜单与面包屑显示“招投标信息维护”
+    - 列表显示“中标供应商”“参与供应商数”
+    - 新增弹窗显示供应商明细表，并可新增供应商行
+    - 详情弹窗显示供应商明细表与中标标识
+  - 联调过程中发现列表 SQL 因 join 后字段未加别名导致 `purchase_id is ambiguous`，已修复并复验通过。

+## 测试进程清理
+- 已关闭 Playwright 浏览器会话。
+- 已停止前端 `npm run dev` 进程。

+# ruoyi-ui 添加 .nvmrc 实施记录
+
+## 文档信息
+
+- 保存路径：`docs/reports/implementation/2026-04-22-ruoyi-ui-nvmrc-implementation.md`
+- 实施日期：2026-04-22
+- 关联范围：`ruoyi-ui` 前端工程本地 Node 版本约束
+
+## 本次修改内容
+
+1. 确认 `docs/` 内近期前端实施计划与实施记录均使用 `nvm use 14.21.3` 作为 `ruoyi-ui` 的实际 Node 版本。
+2. 在 `ruoyi-ui` 目录新增 `.nvmrc`，写入 `14.21.3`，统一本地开发、构建与测试时的 Node 版本入口。
+3. 保持 `package.json` 现有 `engines` 配置不变，本次仅补充 `nvm` 版本声明文件，不扩展其他构建配置。
+
+## 影响范围
+
+- 前端：`ruoyi-ui/.nvmrc`
+- 文档：本实施记录
+
+## 验证情况
+
+1. 版本依据核对：
+   - 已核对 `docs/plans/frontend/` 与 `docs/reports/implementation/` 中近期前端构建命令，当前统一使用 `nvm use 14.21.3`。
+2. 本地命令校验：
+   - 执行命令：`source ~/.nvm/nvm.sh && cd ruoyi-ui && nvm use`
+   - 预期结果：自动读取 `.nvmrc` 并切换到 `v14.21.3`。
+3. 说明：
+   - 本次为 Node 版本声明文件补充，不涉及业务代码、页面交互或接口行为变更，未执行额外前端构建与页面测试。

+# 招聘信息新增编辑弹窗宽度调整实施记录
+
+## 文档信息
+
+- 保存路径：`docs/reports/implementation/2026-04-22-staff-recruitment-dialog-width-implementation.md`
+- 实施日期：2026-04-22
+- 关联范围：招聘信息管理前端页面
+
+## 本次修改内容
+
+1. 定位到招聘信息管理页新增/编辑共用同一个 `el-dialog`，原宽度固定为 `900px`。
+2. 将新增/编辑弹窗宽度改为 `80%`，使弹窗按页面可视宽度自适应放大。
+3. 保持招聘信息详情弹窗宽度和原有表单提交流程不变，避免影响非本次需求范围的交互。
+4. 新增本次前端实施计划与实施记录，沉淀改动背景、影响范围与验证结论。
+
+## 影响范围
+
+- 前端：`ruoyi-ui/src/views/ccdiStaffRecruitment/index.vue` 新增/编辑招聘信息弹窗。
+- 文档：新增前端实施计划与实施记录。
+
+## 验证情况
+
+1. 前端构建校验：
+   - 执行命令：`source ~/.nvm/nvm.sh && nvm use 14.21.3 >/dev/null && cd ruoyi-ui && npm run build:prod`
+   - 结果：构建成功；存在项目原有的 bundle size warnings，本次改动未引入新的构建错误。
+2. Playwright 浏览器实测：
+   - 执行方式：通过 `nvm use 25.9.0` 启动 `playwright-cli`，打开 `http://127.0.0.1:1025/prototype/staff-recruitment?preview=1&mode=add` 与 `http://127.0.0.1:1025/prototype/staff-recruitment?preview=1&mode=edit`，在真实浏览器中读取可见 `el-dialog` 的实际宽度。
+   - 结果：新增弹窗标题为“添加招聘信息”，页面宽度 `1280px`、弹窗宽度 `1024px`、宽度占比 `0.8`；编辑弹窗标题为“修改招聘信息”，页面宽度 `1280px`、弹窗宽度 `1024px`、宽度占比 `0.8`，与需求一致。
+3. 测试进程清理：
+   - 已关闭本次测试过程中临时启动的 Playwright 浏览器与前端 dev server。
