+/**
+ * 课程作业接口封装（P0 标准化后新契约，P1-7 TS 契约化）。
+ *
+ * 前缀说明：conf.serviceHost 本地为空（走 vite 代理），线上为基础平台域名；
+ * platform 固定使用 "api"，与后端 Config.API_PATH 中的 api 匹配。
+ * 统一响应由 alova-iview 解包为 data（code==0），页面直接使用返回值。
+ *
+ * 变更要点（P0）：
+ * 1. 作业域去掉 Homework_list 二级段（/api/homework/Homework_list/List → /api/homework/List）
+ * 2. 文件域从 base/ 迁移到 file/（/api/base/FileDown → /api/file/Down）
+ * 3. 字典域从 base/ 迁移到 dict/，GET 写操作改 POST（/api/base/DelDept → /api/dict/Delete）
+ * 4. postJSON 用于 @RequestBody 接口；postForm 用于 @RequestParam 接口（表单提交）
+ * 5. 参数更名：chaoSend→fileIds、topmost→smsFlag
+ * 6. Delete 入参从 ids 逗号串改为 List<Integer> JSON 数组
+ *
+ * 变更要点（P1-7）：
+ * 7. 全部方法加返回值泛型标注，替换 Record<string, any>
+ * 8. 列表分页 content 字段对齐后端 BasePageResult（非旧 list）

+ * 2. 文件域从 base/ 迁移到 file/（/api/base/FileDown → /api/file/Down）
+ * 3. 字典域从 base/ 迁移到 dict/，GET 写操作改 POST（/api/base/DelDept → /api/dict/Delete）
+ * 4. postJSON 用于 @RequestBody 接口；postForm 用于 @RequestParam 接口（表单提交）
+ * 5. 参数更名：chaoSend→fileIds、topmost→smsFlag
+ * 6. Delete 入参从 ids 逗号串改为 List<Integer> JSON 数组
+ *
+ * 变更要点（P1-7）：

+# 课堂作业前端 M5 切换计划 —— 对齐后端 V2 接口完成页面
+
+| 项 | 内容 |
+|---|---|
+| 项目 | 前端 `E:\YHXT\view\CourseHomework`（Vue3 + Vite + TS + view-ui-plus + alova） |
+| 依据 | 后端 `E:\YHXT\java\ClassHomeWork` 已实现接口（M1~M4 完成，V3.2 运行验证通过）+ `classwork-homework-plan-v3.md` §11 前端适配计划 / §15.5 遗留待办第 1 条 |
+| 目标 | 前端 9 个核心页面全部切换到 V2 接口面，打通「发布→统计→批阅→学生提交→结果」全链路联调 |
+| 后端地址 | 本地 `http://localhost:8102`（vite proxy 已配置，无需改动） |
+| 文档版本 | V1.0（2026-09-15） |
+
+---
+
+## 1. 背景与现状差距
+
+### 1.1 后端权威接口面（已实现，本计划的对齐目标）
+
+后端按 PRD §18 完成了 V2 接口（28 个新端点），同时保留 V1 冻结接口（17 个）。统一响应 `{code,msg,data}`，分页 `BasePageResult`，时间格式全局 `yyyy-MM-dd HH:mm:ss`（无 "T" 分隔符）。
+
+**教师端 `/api/teacher/homeworks`（19 端点，PRD 页 1~6）：**
+
+| 方法 | 路径 | 用途 |
+|---|---|---|
+| POST | `` | 创建作业（一律落草稿 DRAFT_UNPUBLISHED） |
+| PUT | `/{id}` | 编辑作业（仅草稿两态） |
+| DELETE | `/{id}` | 删除作业（仅草稿两态） |
+| POST | `/{id}/publish` | 立即发布 |
+| POST | `/{id}/schedule` | 定时发布 / 取消定时（`{scheduledAt}` 或 `{cancel:true}`） |
+| GET | `/drafts` | 草稿箱分页（`subject`/`hwStatus`/`keyword` 筛选） |
+| GET | `/published` | 已发布列表分页（含应交/已读/已交/未读未交聚合） |
+| POST | `/{id}/remind` | 提醒未读/未交（`{type: NOT_READ\|NOT_SUBMITTED, studentIds?}`，返回 `{reminded}`） |
+| POST | `/{id}/extend` | 延长截止（`{deadlineAt}` 须晚于当前值） |
+| POST | `/{id}/copy` | 复制为新草稿，返回新 id |
+| POST | `/{id}/archive` | 归档（只读，屏蔽提醒） |
+| GET | `/{id}/export` | 导出学生矩阵 Excel（文件流） |
+| GET | `/{id}` | 作业详情 |
+| GET | `/{id}/stats` | 汇总统计卡片（总进度 + 分班进度） |
+| GET | `/{id}/students` | 学生矩阵分页（`classId`/`submitStatus`/`reviewStatus`/`pendingGrade` 筛选） |
+| POST | `/{id}/submissions/{studentId}/review` | 保存批阅（`{score?, comment?, markedImages?}`，score/comment 至少一项） |
+| POST | `/{id}/submissions/{studentId}/return` | 打回（`{comment}` 必填） |
+| GET | `/{id}/submissions/{studentId}/versions` | 历史提交版本列表 |
+| GET | `/classes` | 年级→班级树（叶子 id=classId，含 studentCount） |
+| POST | `/classes/sync` | 手动触发名册同步 |
+
+**学生端 `/api/student/homeworks`（6 端点，PRD 学生页 1~3）：**
+
+| 方法 | 路径 | 用途 |
+|---|---|---|
+| GET | `` | 我的作业列表（`tab=all/todo/done/closed` + 分页/keyword） |
+| GET | `/{id}` | 作业详情（含 description/attachments/myAttachments/myText） |
+| POST | `/{id}/read` | 阅读上报（前端停留 ≥3 秒后调用，幂等） |
+| POST | `/{id}/submissions` | 提交作业（`{text?, attachments[]}`），返回 `{submissionId}` |
+| PUT | `/{id}/submissions/{submissionId}` | 撤回/打回重交（`{action: withdraw\|resubmit, text?, attachments?}`） |
+| GET | `/{id}/result` | 批阅结果（当前版本 + 历史版本含各版评语） |
+
+**通知 `/api/notifications`（3 端点）**：GET 分页（含未读数）、`POST /{id}/read`、`POST /read-all`。
+
+**辅助域（已存在，继续沿用）**：文件 `/api/file/Upload|UploadImage|Down|Preview|Delete|List|Bind`；字典 `/api/dict/List|ManageList|Add|Update|Delete|Sort|Sync`；联系组 `/api/contacts/*`；`/api/base/GetUserInfo|GetUserMod|GetSchoolAll|GetGroupUser|FileUpload|Logout`。
+
+**V1 冻结接口 `/api/homework/*`（17 个）**：继续服务未切换页面（如「已收到」收件箱、「全部作业」管理端、「作业统计」），M5 完成后评估退役。
+
+### 1.2 前端现状盘点与技术债
+
+页面与数据源核对结果（`homeworkApi.*` 实际调用 vs 后端真伪）：
+
+| 页面 | 路由 | 现状数据源 | 判定 |
+|---|---|---|---|
+| NewHomework.vue | /list/new | 旧 Create/Edit/GetDetail | 真实接口，需切 V2 |
+| HomeworkList.vue | /list、/homeworklist | 旧 SendList + **remind（伪）** | 部分伪接口 |
+| HomeworkDetails.vue | /list/detail | 旧 Detail/GetNextPrev/ReadDetail | 真实接口，需切 V2 |
+| Submissions.vue | /submissions | **Submissions/SubmissionDetail/grade（伪）** | 全部伪接口 |
+| Grade.vue | /grade | **sendList + Submissions/SubmissionDetail/grade（伪）** | 部分伪接口 |
+| StudentHomeworks.vue | /stu/today、/stu/redo、/par/kids | **MyHomeworks/parentNudge（伪）** | 全部伪接口 |
+| HomeworkAccept.vue | /accept | 旧 List/Detail（v1 收件箱） | 真实接口，需改造为学生详情页 |
+| HomeworkStats.vue | /stats | 旧 Statis | 真实接口，保留 |
+| HomeworkSetting.vue | /setting | dict/contacts | 真实接口，保留 |
+| ApprovalList.vue | /approval | **approvalList/approve/reject（伪）** | 后端无审批域 |
+| ApprovalSetting.vue | /approval-setting | **approvers 系（伪）** | 后端无审批域 |
+
+**「伪接口」清单**（后端不存在，真实环境必 404，仅 mock 模式可跑）：`/api/homework/` 下的 `Submissions、SubmissionDetail、Grade、Remind、MyHomeworks、MySubmission、Submit、ParentNudge、ApprovalList、ApprovalCount、Approve、Reject`；`/api/dict/` 下的 `ApproverPool、Approvers、AddApprover、UpdateApprover、DelApprover`；`/api/base/SetRole`。
+
+**类型契约差距**：`types/homework.ts` 为 V1 契约（hwStatus 四态 `draft/collecting/closed/done`、submitStatus 小写五值）；V2 要求 hwStatus 五态 `DRAFT_UNPUBLISHED/DRAFT_SCHEDULED/PUBLISHED/CLOSED/ARCHIVED`、submitStatus 五态 `NOT_SUBMITTED/SUBMITTED/LATE_SUBMITTED/RETURNED/REVIEWED`、reviewStatus 三态 `PENDING/REVIEWED/RETURNED`。
+
+**工作区未提交改动**：Grade/StudentHomeworks/Submissions 三页的图片预览/上传优化 + mock/env 配置微调（与本次切换方向一致，保留并在其上继续）。
+
+## 2. 总体方案
+
+三层推进：**契约层（类型+API 客户端）→ 教师端页面 → 学生端页面**，最后清理菜单路由与 mock。旧 V1 页面（已收到/全部作业/统计/设置）不动，继续走冻结接口。
+
+### 2.1 契约层（P0）
+
+**新增 `src/types/homeworkV2.ts`**（V2 契约独立成文件，不污染 V1 类型；与后端 `model/v2/*.java` 一一对齐）：
+
+```ts
+/** 作业五态（PRD §17） */
+export type HwStatusV2 = "DRAFT_UNPUBLISHED" | "DRAFT_SCHEDULED" | "PUBLISHED" | "CLOSED" | "ARCHIVED";
+/** 提交五态 */
+export type SubmitStatusV2 = "NOT_SUBMITTED" | "SUBMITTED" | "LATE_SUBMITTED" | "RETURNED" | "REVIEWED";
+/** 批阅三态 */
+export type ReviewStatus = "PENDING" | "REVIEWED" | "RETURNED";
+
+export interface AttachmentItem { fileId?: number; fileUrl: string; fileType?: "image" | "file"; fileName?: string; sort?: number; }
+export interface ClassItem { classId: string; className: string; }
+export interface ProgressVo { should: number; read: number; submitted: number; graded: number; pendingGrade: number; unsubmitted: number; unread: number; unreadUndone: number; readRate: number; submitRate: number; gradeRate: number; }
+export interface HomeworkV2Vo { id; title; subject; description; hwStatus: HwStatusV2; hwStatusDesc; scheduledAt; publishedAt; deadlineAt; archivedAt; submitType: string[]; allowLate; remind1d; remind1h; classes: ClassItem[]; attachments: AttachmentItem[]; publisherId; publisherName; createTime; updateTime; progress?: ProgressVo | null; }
+export interface HomeworkV2Request { title: string; subject?; description?; classIds: string[]; attachments?: AttachmentItem[]; deadlineAt?; submitType: string[]; allowLate?; remind1d?; remind1h?; }
+export interface TeacherHomeworkQuery { pageIndex?; pageSize?; keyword?; subject?; hwStatus?; }
+export interface StudentMatrixVo / StudentMatrixQuery / HomeworkStatsVo / ClassTreeNodeV2（id: string）/ SubmissionVersionVo / StudentHomeworkV2Vo（含 MySubmission）/ StudentHomeworkDetailV2Vo / StudentSubmitRequest / StudentResultVo / NotificationVo …
+```
+
+**新增 3 个 API 客户端**（风格沿 `api/module/homework.ts` 的 `get/postJSON` 封装）：
+
+- `src/api/module/teacherHomework.ts` → `teacherApi`：19 端点全覆盖 + `exportUrl(id)`（Excel 直链，浏览器跳转下载）
+- `src/api/module/studentHomework.ts` → `studentApi`：6 端点
+- `src/api/module/notification.ts` → `notificationApi`：3 端点
+
+**修正 `api/module/homework.ts`**：`baseApi.setRole` 标注仅 mock 可用（后端无此端点，真实环境学生身份由 CAS 登录账号 ↔ class_student 映射，联调用种子账号 stu01~stu06）；`baseApi.getClassTree` 的调用方改走 `teacherApi.classTree()`。
+
+### 2.2 页面改造映射（P1~P3）
+
+| PRD 页面 | 前端页面 | 目标接口 | 关键改造点 |
+|---|---|---|---|
+| 页 1 发布作业 | NewHomework.vue | POST/PUT + /classes + publish/schedule + file/Upload | ① 表单重构：classIds（年级→班级树多选，数据源换 `/teacher/homeworks/classes`）② 新增：截止时间（精确到分钟，空=仅查阅型）、submitType（图片/文件/两者/文本）、allowLate、remind1d/remind1h、定时发布时间 ③ 保存语义拆分：「存草稿」（POST/PUT）与「立即发布」（POST 后调 publish）/「定时发布」（POST 后调 schedule）④ 附件走 file/Upload，组装 AttachmentItem[] ⑤ 编辑回显改 GET /teacher/homeworks/{id}（旧 GetDetail 保留给转发场景） |
+| 页 2 草稿箱 | HomeworkList.vue（/list 增加「草稿箱」段） | GET /drafts | 草稿两态（未发布/定时待发）标签展示；操作：编辑、发布、取消定时（schedule cancel）、删除 |
+| 页 3 已发布列表 | HomeworkList.vue（/list 主段） | GET /published + remind/extend/copy/archive/export | ① 统计列：应交/已读/已交/**未读未交高亮** + 阅读率/提交率（progress）② 状态筛选 PUBLISHED/CLOSED/ARCHIVED ③ 操作组：提醒（NOT_READ/NOT_SUBMITTED，返回 reminded 提示）、延长截止（日期选择，须晚于当前）、复制为新草稿、归档、导出 Excel（直链）④ 行点击进详情 |
+| 页 4 详情/统计 | HomeworkDetails.vue | GET /{id} + GET /{id}/stats | 作业信息卡（五态标签、学科、截止、提交方式、班级、附件下载）+ 统计卡片（总进度 + 分班进度：阅读率/提交率/批阅率、待批阅数） |
+| 页 5 学生矩阵 | Submissions.vue | GET /{id}/students | ① 列：学生/班级/阅读状态（含首末阅读时间）/提交状态（含逾期角标）/提交时间/评分/批阅状态/附件缩略图 ② 筛选：classId、submitStatus、reviewStatus、只看待批阅（pendingGrade）③ 未交学生占位行（submissionId=0）④ 行操作：批阅、打回、提醒单个学生（remind 定向） |

+
+**不动页面**：HomeworkStats（旧 Statis）、HomeworkSetting（dict/contacts）、/accept 的 v1 收件箱语义由 HomeworkAccept 改造承接（路由 `/accept` 重定向到 `/stu/today`）。
+
+### 2.3 路由与菜单调整（P3）
+
+| 项 | 处置 | 理由 |
+|---|---|---|
+| 新增 `/stu/detail`（HomeworkAccept 改造后） | meta `{ role: "student", title: "作业详情", modId: 33 }` | PRD 学生页 2/3 载体 |
+| `/accept` | 重定向 `/stu/today` | v1 收件箱语义被学生列表替代 |
+| `/approval`、`/approval-setting` + 菜单 modId 5/6 | **路由与菜单摘除**（页面文件保留不引） | 后端无审批域（plan-v3 §4.6 顺延），伪接口联调必挂 |
+| `/par/kids` 家长端 | 保留路由但隐藏入口 | 后端无家长接口（plan-v3 §4.6 顺延），parentNudge 为伪接口；页面内调用加守卫 |
+| `/homeworklist` 全部作业、`/stats` 统计、`/setting` 设置 | 保留走 V1 冻结接口 | 冻结接口可用，M5 后评估退役 |
+| 通知中心（可选） | 视排期加 `/notify` 轻量页（notificationApi 3 端点，未读角标） | PRD §18 未列页面，plan-v3 §7.3 补充接口；列为可选项 |
+
+### 2.4 mock 同步（P4）
+
+`src/assets/mock/homeworkapi.ts` 增补 V2 端点 mock（teacher 19 + student 6 + notifications 3），数据模型对齐 `types/homeworkV2.ts`，保证 `npm run dev:mock` 全页面可演示；同时清理伪接口 mock（Submissions/Grade/MyHomeworks/审批系），避免继续误导联调。
+
+## 3. 实施顺序与验收
+
+| 阶段 | 内容 | 验收标准 |
+|---|---|---|
+| P0 契约层 | types/homeworkV2.ts + teacherHomework/studentHomework/notification 三客户端 + homework.ts 修正 | `vue-tsc` 通过；接口路径/参数与本文 §1.1 表逐项一致 |
+| P1 教师端发布链路 | NewHomework + HomeworkList（草稿箱+已发布） | 真实后端（8102）：建作业→存草稿→草稿箱可见→立即发布/定时发布→已发布列表出统计聚合 |
+| P2 教师端批阅链路 | HomeworkDetails（stats）+ Submissions（矩阵）+ Grade（批阅/打回/版本） | 矩阵筛选/缩略图/占位行正确；批阅→学生端可见结果；打回→重交→版本递增 |
+| P3 学生端闭环 | StudentHomeworks + HomeworkAccept + 路由菜单调整 | 用种子账号（stu01~stu06）：列表 tab→详情 3 秒已读→提交→倒计时/逾期分流→撤回留版本→打回重交→查结果 |
+| P4 清理与全量走查 | mock 更新、审批/家长端摘除、全页面回归 | dev(dev) + dev:mock 双模式走查；PRD §18 九页面映射逐格核对 |
+
+每阶段一组语义化 commit；P1 起需要后端 8102 运行 + `sql/v3_seed.sql` 名册种子（库名 `class_homework`，utf8mb4）。
+
+## 4. 风险与开放问题
+
+| # | 事项 | 影响 | 处置建议 |
+|---|---|---|---|
+| 1 | 学生身份联调：后端无 SetRole，学生接口按 CAS 登录账号 ↔ class_student 映射 | 高（P3 阻塞） | 与后端确认本地登录方案（种子账号 stu01~stu06 走 CAS 或本地放行）；mock 模式保留 SetRole 演示用 |
+| 2 | 审批域下线需产品确认 | 中 | 本计划先摘菜单/路由不删代码；产品若要保留需后端补接口 |
+| 3 | 提交附件契约：v2 只收 file/Upload 产物（fileId/fileUrl），拒绝 dataURL | 中 | HomeworkUpload 组件改造为真实上传后再组装 AttachmentItem；改造前 dataURL 直交必被后端拒 |
+| 4 | 学生端入口与菜单结构（/stu/* 不在现有静态菜单） | 低 | 沿用现有约定，学生视角由平台角色决定入口；具体待 GetUserMod 对接方案 |
+| 5 | Excel 导出/export 直链需带登录态 cookie | 低 | 同源代理下 `location.href` 直跳即可（与 AllFileDown 同模式） |
+| 6 | V1 页面（已收到/全部作业/统计）与新数据并存的两套状态口径 | 低 | 双轨期 hwStatus 派生映射（后端已做），前端不做转换；M5 后评估 V1 退役 |
+| 7 | tab=redo（待订正）语义：V2 无独立 redo 桶，RETURNED 归入 todo | 低 | /stu/redo 路由 initTab 改 todo 并在页内强化 RETURNED 过滤，或改路由为 /stu/todo |
+
+## 5. 交付物清单
+
+1. `src/types/homeworkV2.ts` —— V2 全量类型契约
+2. `src/api/module/teacherHomework.ts` / `studentHomework.ts` / `notification.ts` —— 28 端点客户端
+3. 改造后 7 个页面：NewHomework / HomeworkList / HomeworkDetails / Submissions / Grade / StudentHomeworks / HomeworkAccept
+4. `src/router/routes.ts` + `src/assets/config/menu.ts` 调整
+5. `src/assets/mock/homeworkapi.ts` V2 增补与伪接口清理
+
+---
+
+## 6. 审核（审批）功能下线（2026-09-15）
+
+### 6.1 裁决变化
+
+§2.3 与 §4 风险 2 原口径为「摘菜单/路由、页面文件保留不引，等产品确认」。本次确认**彻底删除审批（审核）功能**：产品定位为任课教师直接布置，不存在送审环节；后端 `ClassHomeWork` 从未实现审批域（无 `approval_*` 列、无 `ApprovalList/Approve/Reject`、无审批人池接口），而前端两页调用的 `homeworkApi.approvalList/approve/reject` 与整个 `approvalSettingApi` **在 API 层根本不存在**，属编译期即悬空的死代码。
+
+注意边界：本节只删「审批/审核」（approval），**不动「批改/批阅」（grade/review）**——`Grade.vue`、`Submissions.vue`、`ReviewModal.vue` 是作业核心链路。
+
+### 6.2 牵连面盘点（grep `approval|审核|审批|approver|canApprove|vote|flow` 全仓）
+
+| # | 文件 | 现状 | 处置 |
+|---|---|---|---|
+| 1 | `src/views/homework/ApprovalList.vue` | 审批列表页，未挂路由，调用不存在的 `homeworkApi.approvalList/approve/reject` | 删除（git 跟踪，可 `git checkout` 恢复） |
+| 2 | `src/views/homework/ApprovalSetting.vue` | 审批人池设置页，未挂路由，调用不存在的 `approvalSettingApi` | 删除（同上） |
+| 3 | `src/components/ApprovalFlowEditor.vue` | 工作区已处于删除态（`git status` 显示 ` D`） | 保持删除，不恢复 |
+| 4 | `src/types/homework.ts` | `HomeworkVo` 81-95、`ApprovalStatus` 103、`HomeworkDetailVo` 146-174（含 `approvalFlow`/`canApprove`）、`HomeworkRequest` 393-398（`approvers`/`vote`/`flow`）、`ApprovalQuery` 489、`ApprovalAction` 500、`ApproverVo` 509、分节标题 476 | 全部删除；分节标题改「班级」 |
+| 5 | `src/api/module/homework.ts` | 23-24 `import { ApprovalQuery, ApproverVo }`（导入后零使用） | 删两行导入 |
+| 6 | `src/assets/config/menu.ts` | 12-13 静态菜单 `id/modId 5 审批列表 /approval`、`6 审核设置 /approval-setting`（指向不存在的路由） | 删两行 |
+| 7 | `src/utils/menuRoute.ts` | 无审批别名；但 `resolveMenuPage` 对无法识别的模块只 `console.warn` 并返回 `path:""`，而 `layout.vue:192` 直接渲染 `modList`（不过滤空 path）→ 平台 `GetUserMod` 若仍下发 modId 5/6，侧栏会出现点了没反应的死菜单 | 新增 `DROPPED_MOD_IDS={5,6}` + `dropDroppedModules(list)`（顶层 + children，按 `modId ?? id`，不改入参），`App.vue` 赋值 `layoutData.modList` 前调用 |
+| 8 | `src/assets/mock/homeworkapi.ts` | 审批引擎与数据：头注释 7/15-16、审批人池 41-52、`buildFlowFromInput` 62-72、`pendingApprovers` 75-79、`canAct` 81-84、`flowProgressText` 86-92、种子 `approval*` 字段 155-313（7 处）、`seedFlows` 318-343、复位循环 345-353、`isPublished` 639-641、`APPROVAL_DESC` 648、列表映射 682-689、详情映射 728-753、Create 1026-1032、Edit 1059-1092 | 全删；`isPublished` 简化为「非草稿即可见」；种子行不再带 `approval*` 键 |
+| 9 | 其余 `src/views`、`src/components`、`src/router`、`App.vue` | grep **零命中** | 无需改动 |
+
+后端 `E:\YHXT\java\ClassHomeWork`：审批域从未落地，无可删代码；仅需把 `classwork-homework-plan-v4.md` 的 §0 排除说明与 Q-08 由「待确认」改为「已裁决下线」。
+
+### 6.3 执行步骤与验收
+
+1. 备份：`types/homework.ts`、`api/module/homework.ts`、`assets/mock/homeworkapi.ts`、`assets/config/menu.ts`、`utils/menuRoute.ts`、`App.vue` 快照到 `.backup/20260915-drop-approval/`（这些文件工作区相对 HEAD 已有 M5 未提交改动，`git restore` 会连带丢改动，故单独快照）。
+2. 删 2 个页面文件（`git rm` 语义，历史可查）。
+3. 按 6.2 顺序改 types → api → menu → menuRoute+App → mock（自底向上，先断引用再清数据）。
+4. 验收（实测见 §6.4）：① `grep -rniE "approval|approver|canApprove" src` 命中数为 0；② `npm run build` 成功；③ `dev:mock` 下逐端点冒烟正常、审批端点 404、侧栏无审批入口。
+   > 原定的 `npx vue-tsc --noEmit` 门禁在本工程**跑不起来**：`vue-tsc@1.8.27` 与 `typescript@5.9.3` 不兼容会直接崩溃，且工程 tsc 基线本就有 65 条存量报错。故类型侧只作「不得新增引用已删符号的报错」的对照检查，见 §6.4 第 4 条。
+5. 结果回填 §6.4。
+
+### 6.4 执行结果回填（2026-09-15 完成）
+
+**改动清单**
+
+| 文件 | 动作 |
+|---|---|
+| `src/views/homework/ApprovalList.vue`、`ApprovalSetting.vue` | `git rm`（索引内 `D`，历史可查） |
+| `src/components/ApprovalFlowEditor.vue` | 保持工作区已删除状态，未恢复 |
+| `src/types/homework.ts` | 删 `HomeworkVo` 8 个 approval 字段、`ApprovalStatus`、`HomeworkDetailVo` 9 个 approval 字段（含 `approvalFlow`/`canApprove`）、`HomeworkRequest` 的 `approvers/vote/flow`、`ApprovalQuery`/`ApprovalAction`/`ApproverVo`；分节标题「班级 / 审批」→「班级」 |
+| `src/api/module/homework.ts` | 删 `ApprovalQuery`、`ApproverVo` 两个死导入 |
+| `src/assets/config/menu.ts` | 删 modId 5「审批列表」/6「审核设置」两项，头注释记录「平台若仍下发则由 DROPPED_MOD_IDS 剔除」 |
+| `src/utils/menuRoute.ts` | 新增 `DROPPED_MOD_IDS={5,6}`、`DROPPED_NAMES`（审批/审核 7 个叫法）、`dropDroppedModules()`（顶层+children，按 `modId ?? id` 或名称命中，返回新数组不改入参） |
+| `src/App.vue` | `GetUserMod` 结果入壳层前经 `dropDroppedModules` 过滤（侧栏渲染、默认跳转、console.table 共用同一份） |
+| `src/assets/mock/homeworkapi.ts` | 删审批引擎（审批人池 `approvers/approverSeq/approverName/approverPoolAccounts`、`FlowLevel`、`buildFlowFromInput`、`pendingApprovers`、`canAct`、`flowProgressText`、`APPROVAL_DESC`）、`seedFlows()` 与其后的复位 forEach、种子 8 处 approval 属性、`toVo`/详情两处 8 行映射与 `approvalFlow` 块、Create 新对象的 7 行 approval 初始化、Edit 的 flow 重建整段（35 行）；`isPublished()` 由「审批通过或免审」改为 `hwStatus !== "draft"`；头注释与存储注释同步改写 |
+
+**验收实测**
+
+1. **残留归零**：`grep -rniE "approval|approver|canapprove|flowprogress|buildflow" src` → **0 命中**（中文「审批/审核」仅存于注释与 `DROPPED_NAMES` 名单，属有意保留）。
+2. **构建通过**：`npm run build`（`vite build --mode base`）**EXIT=0**，18.82s。
+3. **mock 冒烟**（`npm run dev:mock` @8077，node fetch 逐端点，全部 `code==0`）：
+   - `List` 5/7 条、`SendList?scope=user` 3/3 条、`Detail?serid=1&type=0` 出参键仍为 `serid/Contents/DeptID/...ChaoSend/tlist` 且**不再含任何 approval 键**、`ReadDetail` 按班级分组（`account=1301`/`teaname=初一(1)班（45人）`）、`MyHomeworks` buckets `{todo:3,submitted:1,graded:2,redo:0,all:7}`、`Statis` 11 字段齐全、`GetClassTree` 年级→班级带 `studentCount`。
+   - 审批端点确认消失：`/api/homework/ApprovalList`、`/api/dict/ApproverPool` 均 **HTTP 404**。
+   - 临时服务已按 PID 校验（命令行确为本工程 `vite.js --mode mock`）后 taskkill，8077 已释放。
+4. **类型检查工具链本身不可用（既有问题，非本次引入）**：`vue-tsc@1.8.27` 在 `typescript@5.9.3` 下直接崩溃（`Search string not found: "/supportedTSExtensions = .*(?=;)/"`，vue-tsc 1.x 的 monkey-patch 与 TS 5.5+ 不兼容）。退化用 `npx tsc --noEmit` 得 **65 个报错，全部为存量**：alova 泛型 `TS2344 Type 'T' does not satisfy the constraint 'AlovaGenerics'`（连未改动的 `notification.ts`/`teacherHomework.ts`/`studentHomework.ts` 同样报）、mock 种子数组属性推断 `TS2339`、`menu.ts` 的 `IModule` 未从 `@/store` 导出、`teacherNames` 未使用等；**其中无一条引用被删除的审批符号**（已 grep 验证）。→ 建议后续单列一项：升级 `vue-tsc` 到 2.x 或锁 `typescript<=5.4`，否则类型门禁形同虚设。
+
+**行为变化（预期内）**：原先 `pending`/`rejected` 的演示种子不再被门控，收件箱从 6 条变 7 条、`Statis.publishedCount` 7/8；这符合「无送审环节，发布即可见」的产品口径。
+
+**回退方式**：`git checkout HEAD -- src/views/homework/ApprovalList.vue src/views/homework/ApprovalSetting.vue` 可复原页面；types/api/menu/menuRoute/App/mock 六个文件的改动前快照在 `.backup/20260915-drop-approval/`（因工作区相对 HEAD 另有未提交的 M5 改动，直接 `git restore` 会连带丢 M5，故用快照）。
+
+---
+
+## 7. 应用设置功能下线（2026-09-15）
+
+### 7.1 裁决
+
+「应用设置」（路由 `/setting`，modId 21）承载两块能力：**发文部门字典**（`dict/ManageList·Add·Update·Delete·Sort`）与**自定义联系组**（`contacts/GetGroup·AddGroup·EditGroup·DelGroup·GetContactsTea·SetContactsTea·GetGroupTree`），任课教师布置作业不依赖它们。裁决：
+
+- **只删前端**：后端 `DictController`/`ContactsController` 及其 `sys_dict`/`contacts_group`/`contacts_group_user` 表**保留不动**（`HomeworkService.resolveDeptName` 仍要查 `sys_dict`；端点无人调用不影响运行）。
+- **仅该页使用的组件与死 API 一并清掉**（与 §6 同一口径）。
+
+### 7.2 牵连面盘点
+
+| 文件 | 现状 | 处置 |
+|---|---|---|
+| `src/views/homework/HomeworkSetting.vue` | 应用设置页（部门拖拽排序 + 联系组及组员维护） | 删除（git 跟踪） |
+| `src/components/TypeSetBox.vue` | 仅被 HomeworkSetting 引用（全仓 grep 零其他消费者） | 删除 |
+| `src/components/UserCheckInput.vue` | 零消费者（其 `loader` 用 `baseApi.getSchoolAll` + `settingApi.getGroupTree`） | 删除 |
+| `src/router/routes.ts` | `/setting` 路由（86-91）+ 旧路径重定向 `/homework/setting`（121）+ 头注释 `21=应用设置` | 删两处路由与注释项 |
+| `src/assets/config/menu.ts` | `{ id: 21, modId: 21, name: "应用设置", page: "/setting" }` | 删除 |
+| `src/api/module/homework.ts` | `class SettingApi`（12 个方法）+ `export const settingApi`；`BaseApi.getSchoolAll`；`HomeworkApi.getSysDic`(dict/List)、`getSchModuleIsSms`(dict/Sync) 自 §6 后零调用 | 全部删除 |
+| `src/types/homework.ts` | `DeptManageItem`、`DictOption`、`ContactGroupPage`、`ContactUserPage`、`ContactGroupItem`、`ContactUser` | 删除 |
+| `src/assets/mock/homeworkapi.ts` | `/api/base/GetSchoolAll`(682)、`/api/dict/*`(692-741)、`/api/contacts/*`(1173-1250) 三组桩；种子 `groups/groupSeq`(412-418)、`idNames`(420)、`teacherNames`(425，本就是死码)、`schoolTree`(431)、`deptSeq`(31) | 全部删除；头注释端点清单同步改写 |
+
+### 7.3 明确保留项（勿顺手删）
+
+| 保留 | 理由 |
+|---|---|
+| mock 的 `deptDict`（21-30） | Create(830)/Edit(867) 仍用 `deptDict.find(d => d.CodeID === b.deptId)` 解析部门名，是作业域数据来源，不是设置页专属 |
+| `src/components/UserCheckModal.vue`、`ClassCheckInput.vue` | 发作业选班级仍在用 |
+| `src/components/MyConfirm` | HomeworkList / TeacherHomeworks 仍在用 |
+| 类型 `SchoolTreeNode` | `BaseApi.getUserInfo` 的返回类型仍引用它 |
+| `vuedraggable` 依赖 | 删除后成未用依赖，但改 `package.json`/lock 属额外风险，本次不动（后续清依赖时一并处理） |
+| 后端 `dict/*`、`contacts/*` 端点与三张表 | 按 7.1 裁决保留 |
+
+### 7.4 对后端 V4 方案的连带影响（需同步改 `classwork-homework-plan-v4.md`）
+
+1. **E-01 修法调整**：原计划「`deptId` 为空时回填字典默认发文部门」失去维护入口，改为**从当前教师主组/`BoaUser.getCurrentRole()` 推导** `deptId/deptName`，`sys_dict` 仅作为已有数据的名称解析（`resolveDeptName` 保持）。
+2. **E-05 面收窄但过滤器仍必需**：`postForm` 的 14 处调用点里，dict 4 处 + contacts 6 处随本功能下线归零，剩余 `Remind`(N-04 新门面)、`ReceiveUsers`、`UserPull`、`SetTopmost`、`Expedite`、`InitializeRed`(无参) —— `SingleValueParameterFilter` 照旧要做，只是回归面变小。
+
+### 7.5 执行步骤与验收
+
+1. 快照受影响文件到 `.backup/20260915-drop-app-setting/`。
+2. `git rm` 三个文件 → 删路由/菜单 → 删 SettingApi 与死方法 → 删 types → 清 mock（端点 + 专属种子）。
+3. 验收：① `grep -rniE "settingApi|DeptManageItem|ContactGroup|ContactUser|DictOption|getSchoolAll|getGroupTree|TypeSetBox|UserCheckInput|homework_setting" src` 命中 0；② `npm run build` EXIT=0；③ `dev:mock` 冒烟：`List/SendList/Detail/ReadDetail/MyHomeworks/Statis/GetClassTree` 仍全 `code=0`，`/api/dict/*`、`/api/contacts/*`、`/api/base/GetSchoolAll` 均 404，`Create` 仍能解析 `deptName`（回归 §7.3 第一条）；④ 侧栏无「应用设置」。
+4. 结果回填 §7.6。
+
+### 7.6 执行结果回填（2026-09-15 完成）
+
+**改动清单**
+
+| 文件 | 动作 |
+|---|---|
+| `src/views/homework/HomeworkSetting.vue`、`src/components/TypeSetBox.vue`、`src/components/UserCheckInput.vue` | `git rm` |
+| `src/router/routes.ts` | 删 `/setting` 路由 + `/homework/setting` 重定向（目标已不存在，留着会把用户导向未知路由）；头注释 modId 对照去掉 `21=应用设置` |
+| `src/assets/config/menu.ts` | 删 `{ id: 21, modId: 21, 应用设置 }`，头注释改为「不做审批、不开放应用设置」 |
+| `src/utils/menuRoute.ts` | `DROPPED_MOD_IDS` 扩为 `{5, 6, 21}`，`DROPPED_NAMES` 增「应用设置 / 作业设置」——平台 `GetUserMod` 若仍下发 modId 21，侧栏不会出现死菜单 |
+| `src/api/module/homework.ts` | 删 `class SettingApi`（12 方法）与 `settingApi` 导出、`BaseApi.getSchoolAll`、`HomeworkApi.getSysDic`/`getSchModuleIsSms`、`DICT`/`CONTACTS` 前缀常量、4 个类型导入；头注释第 3 条改写 |
+| `src/types/homework.ts` | 删 `DictOption`、`DeptManageItem`、`ContactGroupItem`、`ContactGroupPage`、`ContactUser`、`ContactUserPage`；分节改名为「基础平台」（保留 `SchoolTreeNode`） |
+| `src/assets/mock/homeworkapi.ts` | 删 `dict` 6 桩 + `contacts` 7 桩 + `GetSchoolAll` 桩；删种子 `groups/groupSeq`、`idNames`、`teacherNames`（本就是死码）、`schoolTree`、`deptSeq`；头注释与 `deptDict` 注释同步改写。**`deptDict` 按 §7.3 保留** |
+
+**验收实测**
+
+1. **残留归零**：手写代码中 `settingApi|DeptManageItem|ContactGroup|ContactUser|DictOption|getSchoolAll|getGroupTree|TypeSetBox|UserCheckInput|homework_setting|deptSeq` **0 命中**。另有 12 处 grep 命中经逐条核对均非残留：`src/api/apiDefinitions.ts` 与 `globals.d.ts` 是 `npm run api:gen` 生成的 swagger 快照（镜像后端现状，后端端点仍在，属正确内容）；其余为 `SchoolTreeNode` 被大小写不敏感的 `schoolTree` 模式误命中。
+2. **构建通过**：`npm run build` **EXIT=0**，16.79s。
+3. **mock 冒烟**（`dev:mock` @8077）：保留面 9 个端点全 `code=0`（`List` 5/7、`SendList` 3/3、`Detail`、`ReadDetail` 3 组、`MyHomeworks` buckets `{todo:3,submitted:1,graded:2,redo:0,all:7}`、`Statis`、`GetClassTree`、`GetUserInfo`、`GetUserMod`）；**§7.3 保留项回归**：`Create(deptId:"D002")` → `GetDetail` 仍解析出 `DeptName="数学教研组"`、`DeptID="D002"`，说明 `deptDict` 未误删；已删端点 6/6 全部 **404**（`dict/List`、`dict/ManageList`、`dict/Sync`、`contacts/GetGroup`、`contacts/GetGroupTree`、`base/GetSchoolAll`）。临时服务按 PID 命令行确认归属后 taskkill，8077 已释放。
+4. **类型侧**：沿用 §6.4 第 4 条结论（`vue-tsc@1.8.27` 与 `typescript@5.9.3` 不兼容、工程 tsc 基线 65 条存量错），本次只核对「无引用已删符号的新报错」。
+
+**遗留（有意不动）**：`vuedraggable` 依赖失去唯一使用者，留待统一清依赖时处理；`apiDefinitions.ts`/`globals.d.ts` 待下次 `npm run api:gen` 自然刷新；后端 `dict/*`、`contacts/*` 与三张表按裁决保留。
+
+**回退方式**：`git checkout HEAD -- src/views/homework/HomeworkSetting.vue src/components/TypeSetBox.vue src/components/UserCheckInput.vue` 复原三文件；routes/menu/menuRoute/api/types/mock 六个文件的改动前快照在 `.backup/20260915-drop-app-setting/`。
