UX 缺陷修复:
- 校验失败不再卡死弹窗按钮(Users/Roles/Bills)
- 押金收取/批量收取/添加分期防重复提交;切换房型重置勾选
- AI 表单/批量确认不再出现"假成功"
- Dashboard 各数据模块独立加载,单接口失败不再整页清零
- 房间可视化加载失败显示错误态而非永久转圈
- 学生编辑表单回填前重置,避免字段残留污染
- 覆盖式导入增加二次确认;恢复默认考勤时段确认并同步表单
- 金数据匹配关闭前确认,同步中禁止误关

体验提升:
- 新增统一 QueryErrorState/QueryEmpty,20+ 页面加载失败显示错误态与重试
- 全局 ErrorBoundary + RouteKeeper 逐页兜底
- 新增 usePageVisible/useVisibleRefetch,保活页面切回自动刷新数据
- 新增首次登录角色引导 RoleTour 与业务闭环 NextStepHint 引导卡
- 重构 A2UI:useSubmissionState/useXCardSurface 收敛状态与命令生命周期,
  ArtifactErrorBoundary 渲染降级,图表空数据占位
- AI 助手欢迎语与建议话术按角色定制,会话列表空态引导
- 更新 a2ui-contract.md 契约文档说明实现现状

 ## 完成后报告
 改动文件清单、跑过的测试命令与结果、与契约的偏差说明。

+## 实现现状补充（2026-08 修订）
+
+> 前端 `apps/admin/src/components/AiChat/**` 的实际实现已演进为「统一 artifact」协议，
+> 本段描述现行事实，供后续开发对齐；上文的 `ui.form`/`AiUiForm`/`uiForms` 为早期单轨方案，
+> 当前仅保留历史兼容读取，新写一律走 artifact。
+
+- **统一类型**：`types.ts` 以 `AiArtifactSchema`（`message.uiArtifacts`）为唯一事实源，
+  `artifact.type` ∈ `form | review | chart | import_wizard`，`payload` 携带各类型 schema。
+- **合并逻辑**：`uiArtifacts.ts` 的 `mergeArtifactIntoMessage` 将新 artifact upsert 进
+  `uiArtifacts`，并**向后兼容**地派发到 legacy 字段（`forms`/`reviews`/`charts`）供老消息渲染。
+- **渲染层**：`AiMessageContent.tsx` 消费 legacy 列表渲染 `DynamicForm`/`DynamicReview`/
+  `DynamicChart`；每个制品用 `ArtifactErrorBoundary` 包裹（单个渲染失败不影响整条气泡）。
+- **A2UI 组件实现**：`DynamicForm`/`DynamicReview`/`DynamicChart` 共享
+  `useSubmissionState`（提交状态：防重复提交 + 失败可重试）与 `useXCardSurface`
+  （XCard commands 增量更新 + createSurface 自动去重）。
+- **SSE 事件 / 提交与确认接口**：与上文契约一致，未变更。
+
+后续若彻底移除 legacy 字段，需保证历史消息（持久化 metadata 中的 `forms`/`reviews`/`charts`）
+仍可渲染——建议先迁移历史数据或保留兼容读取。

- 通知中心改为游标分页 + 加载更多,历史通知不再被 50 条上限截断;
  加载失败显示错误态与重试
- AI 流式请求 401 被登出时,登录页提示"登录已过期",不再无声踢出
- AI 附件/引用来源打开失败时给出明确错误提示,不再"点了没反应"
- 新增 useDownload hook:统一导出/下载的防重复、loading 与成功/失败反馈;
  接入学生/账单/房间/入住/费用五个页面的模板下载与导出按钮
- 学生页移除不检查响应状态的私有下载实现,统一走 downloadBlob

- 编辑旧消息会删除其后全部消息时,先弹确认告知影响范围
- 有待发送附件时切换会话,先确认再丢弃(避免静默删除已上传文件)
- EditableCell 保存成功后提供 6 秒内"撤销"入口(把旧值重新保存),
  重新编辑时自动清除
- 导入向导/重新上传显示上传进度条与百分比,不再"假死"
- AI 附件上传透传进度给附件列表
- 租赁合同上传显示按钮 loading 与上传百分比

- 新增 useDirtyGuard hook:关闭弹窗时若表单被修改,先确认再关闭
- 接入 17 个弹窗:账号/密码/档案、角色、教室、宿舍/床位/柜子、
  考勤机、机构、班级、教师、考试、排课、入住/退宿/换房、费用
  (子组件弹窗用 useEffect 在回填后快照,时序正确)
- 学生列表空状态带「添加学生」引导动作
- 排课创建成功提示「同步钉钉」,考试创建成功提示「去详情录成绩」

admin:
- 17 个列表页空态统一为 QueryEmpty 引导:学生/账单/入住/费用/押金/
  教室/房间/班级/考试/排课/机构/考勤机/钱包/租赁/通知/角色等,
  有创建权限的页面附带主操作按钮,无权限时纯展示
- 教师端课堂点名新增「全部已打卡/全部未打卡」批量按钮:
  仅作用于状态不一致的记录,确认后调用批量接口,展示成功/失败数量

server:
- 新增 PUT /attendance-records/batch-status 批量改状态接口
  (ids ≤200,逐条权限校验与会话锁,部分失败返回 failedIds,
  审计日志记录批量结果;路由声明在 :id 之前避免被捕获)

- 原始考勤明细表支持行选择(跨页保留),选中后出现
  「标记正常/标记请假/标记缺勤」批量操作条
- 批量提交前确认,成功后按 updated/failed 数量反馈,
  失败记录(如已结算)提示原因;筛选条件变化自动清空选择
- 复用 PUT /attendance-records/batch-status 接口

- 全模块类型化:controller 的 req: any → AuthenticatedRequest/RequestUser,
  聚合查询 getRawMany 泛型标注、导入行/响应体定义具体 interface、
  catch (e: any) → unknown + 收窄、no-base-to-string 用 String() 显式转换
- 第三方无类型库边界(pdfkit/exceljs)文件级或单行 disable 并注明理由
- 顺带修复:get-business-context.tool 两个 require-await error、
  bills.controller 参数顺序隐患、main.ts compression 调用
- 运行时逻辑零改动;测试 142 套件 / 1065 用例全部通过

- mergeArtifactIntoMessage 不再派发 legacy 列表,只维护 uiArtifacts
- 渲染层从 uiArtifacts 派生 forms/reviews/charts,为空时回退 legacy
  (历史消息兼容,老 metadata 仅 a2uiForm/a2uiReview/a2uiChart)
- sseReducer 删除 ui.form/ui.review/ui.chart 旧事件分支,只消费
  ui.artifact(后端过渡期双发,旧事件将被忽略)
- types.ts legacy 字段标注 deprecated;契约文档同步现状
- 测试更新:旧事件忽略 + uiArtifacts 合并/恢复断言

Standards 轴:
- 移除 uiArtifacts.ts 的 payloadOf 死代码残留
- AttendanceDevices 残留 any 类型化(补 ClassroomOption.status 字段)
- 批量考勤纠错区分业务失败(已结算/无权限)与系统错误,
  前端提示精确到两类数量
- Dashboard queryFn 六段重复校验块收敛为 safeValidate 助手

Spec 轴:
- 补齐阶段 3.4 A2UI 测试:图表空数据占位、ArtifactErrorBoundary
  降级隔离、useSubmissionState/useXCardSurface 单测(7 用例)
- 阶段 2.2 补两处引导:教师工作台区分「今日无课」与「未分配班级」、
  班级花名册空态带「添加学员」动作
- 契约文档修正 DynamicReview 状态管理描述(多提交点如实说明)

- 新增 common/buffer.ts bufferToArrayBuffer:9 处
  'as unknown as ArrayBuffer' 收敛为精确切片(含 byteOffset),
  消除潜在 Buffer 池偏移隐患,类型断言集中到单一实现
- 新增 common/stringify.ts:4 处重复的 stringify 助手收敛为共享实现
- aislop: AI Slop 10→1(仅剩 1 处有理由的 stringify 薄包装,
  eslint no-base-to-string 绕过所需);Code Quality 剩余
  4 重复块(声明式 SQL 配置)+ 2 文件过大(既有规模)均保留
- 测试 142 套件/1065 用例通过

 当用户需要录入或修改业务数据时，先调用 render_form 生成确认表单，提示用户填写并提交；只有在用户通过表单提交确认后，才能执行写操作工具（如 create_student、update_students）。
 新增学生示例：render_form 的 fields 使用 name/phone/gender/studentNo。
 修改学生示例：批量修改姓名/档案时，render_form 的字段可用 name_<学生ID> 等命名展示待修改内容，用户提交后再调用 update_students，每条更新必须带学生 id。
+需要向用户询问信息、让用户选择或确认时（例如：确认导入策略与列映射、选择班级/房型/老师、补充必填信息、二选一确认），优先调用 render_form 生成简短的问题卡片（字段 1-4 个：选项用 select、短文本用 input、日期用 date、多行说明用 textarea），让用户直接在卡片上作答，不要用大段文字逐项提问；只有开放式讨论或无法用表单表达时才用文字提问。问题卡片标题用一句完整问题，字段 label 即选项/问题文案，必填项设置 required。
 当用户上传 Excel 并需要批量导入（学生、宿舍、换宿、入住记录）时，按以下固定流程执行：
 1. 先根据消息附带的 Excel 提取文本（工作表名 + tab 分隔行）判断业务类型与表头，向用户说明将导入什么、依赖什么；需要确认的列映射、校区或策略先在聊天中与用户确认，不要替用户默认做出影响数据的决定。
 2. 用户确认后调用 start_import_wizard：必须传入 attachmentId 和 stages（业务类型 stepKey：students 学生 / rooms 宿舍 / checkins 入住 / transfers 换宿，以及对应工作表 sheet 名），并把确认结果一并传入（mapping 列映射、organization 校区、updateExisting 是否更新已有记录、duplicatePolicy 重复行策略 error/skip、skipUnmatched 是否跳过未匹配行）。系统直接从文件解析行数据，禁止把整表数据抄进工具参数或凭空补全。

+# 管理端 UI/UX 深度优化变更总结（apps/admin）
+
+> 目标：深度优化用户操作的 UI/UX（表单、列表、反馈、导航、加载态、错误态、空状态、移动端适配等），
+> 保持现有 Ant Design 体系与功能不变，最终通过类型检查、lint 与测试验证。
+> 本文件按类别汇总已落地改动与验证记录，供 review 使用。
+
+## 一、错误态（失败不再伪装成"空数据/0 值"，均带重试）
+
+- 工作台 Dashboard：全部接口失败时显示 `QueryErrorState` + 重试（此前静默显示 0 值）。
+- 考试详情页：失败显示错误态 + 重试（此前空白页）。
+- 机构列表 / 操作日志：失败显示错误态 + 重试（此前弹 toast 后渲染空表）。
+- 部分失败反馈：Dashboard 部分接口失败改为页面内可关闭 `Alert`（此前每次切换日期弹 toast）。
+
+## 二、加载态
+
+- 6 个页面骨架屏替代整页 Spin：工作台（统计卡片骨架）、教师工作台、班级详情、考试详情、宿舍可视化、AI 配置。
+- 学生表展开行（多班型对比）加载中显示 Spin + 提示，不再空白。
+- 班级花名册导出按钮 loading（try/finally）。
+
+## 三、空状态
+
+- 复用统一 `QueryEmpty`（描述 + 主操作按钮引导）：学生/宿舍/押金/账单/教室/教师/钱包/机构等列表页已覆盖。
+
+## 四、表单
+
+- 新增 `useSubmitShortcut`：Cmd/Ctrl+Enter 提交，覆盖 12+ 弹窗（学生、宿舍/床位/柜子、押金×4、费用×3、教室、租赁、班级添加学员/教师）。
+- 15 个表单统一 `scrollToFirstError`：校验失败自动滚动到首个错误字段。
+- 防重复提交：考勤时段配置、班级添加学员/教师补齐 `confirmLoading`（其余弹窗已具备）。
+
+## 五、列表
+
+- 表格横向滚动：10+ 个缺失 `scroll.x` 的表格补齐（学生资料 4 Tab、考勤明细、考勤机、钱包、宿舍抽屉、教师工作台、押金弹窗等）。
+- 移动端操作列固定：学生/宿舍/押金/账单/教室/教师/钱包 7 个主列表操作列 `fixed: 'right'`。
+- 手动刷新入口：新增 `RefreshButton`，接入 8 个列表页（学生/宿舍/押金/教室/账单/教师/机构；钱包原有）。
+- 分页/跨页勾选/已选提示均已具备，未改动。
+
+## 六、反馈
+
+- 通知铃铛：全部已读失败给出错误提示；无未读时按钮置灰；铃铛改为可聚焦按钮 + `aria-label`。
+- 统一消息桥（App context）已具备；导出/删除/保存反馈已具备。
+
+## 七、导航
+
+- 新增 `ScrollToTop`：路由切换后滚动复位到顶部。
+- 新增全局 `BackTop`：长列表滚动超过 400px 后浮现"回到顶部"按钮（尊重 reduced-motion）。
+- 登录页用户名自动聚焦。
+- 路由标签（RouteDock）窄屏压缩尺寸，避免横向裁切。
+
+## 八、移动端适配
+
+- 表格横向滚动 + 操作列固定（见"列表"）。
+- `Descriptions` 响应式列数：班级详情、账单详情×2、学生档案、集成配置（此前固定列数在窄屏过挤）。
+- 内容区 padding 已按 breakpoint 响应式（MainLayout 原有）。
+
+## 九、无障碍与质感（全局 CSS）
+
+- `:focus-visible` 品牌蓝焦点环（键盘导航可见）。
+- `@media (prefers-reduced-motion: reduce)` 关闭动画/平滑滚动。
+- `::selection` 品牌色；WebKit 细滚动条；`html` 平滑滚动。
+
+## 新增文件
+
+- `components/RefreshButton.tsx`、`components/ScrollToTop.tsx`、`components/BackTop.tsx`
+- `hooks/useSubmitShortcut.ts`
+- `components/ux.integration.test.tsx`（5 个浏览器用例：RefreshButton / useSubmitShortcut 激活与未激活 / ScrollToTop / BackTop）
+
+## 验证记录
+
+| 检查 | 结果 |
+| --- | --- |
+| typecheck（admin + server） | ✅ |
+| lint（oxlint + eslint） | ✅ 0 warning / 0 error |
+| admin vitest（浏览器） | ✅ 31 文件 / 166 用例 |
+| server jest | ✅ 191 用例 |
+| aislop scan --changes | ✅ 100/100 |
+
+## 未做/后续（可选）
+
+- 运行时视觉走查：需要 MySQL + 后端 + 前端环境（当前本地未运行），用于最终逐页截图核对。
+- AI 助手抽屉：已具备响应式/空态/取消/技能锁定，`submit` 已有请求中防护，未做额外改动。

+## 八、后续建议与落地状态
 
-1. **工作流元数据化**：把闭环顺序与前置依赖做成可配置的 `workflow` 元数据（而不是只写在提示词里），Agent 可按数据状态动态提示。
-2. **完成度感知**：新增“业务待办”查询工具（如“本月未生成账单的入住学生数”“未分班学生数”），让引导有数据支撑。
-3. **前端示例补充**：在技能示例/欢迎语中加入工作流引导话术（如“我可以按‘先学生、再入住、后账单’帮你完成”）。
-4. **逐步确认**：大型导入建议分阶段确认（基础档案 → 关系数据），降低一次性确认风险。
+1. **工作流元数据化**：已落地，闭环顺序与前置依赖在 `agent-context/business-context.registry.ts` 中维护，`get_business_context` 按数据状态动态提示。
+2. **完成度感知**：已落地，`get_pending_tasks` 返回未分班、未入住、未生成账单、租赁缺合同等业务待办计数。
+3. **前端示例补充**：仍可做，欢迎语/技能示例中补充“先学生、再入住、后账单”的工作流话术。
+4. **逐步确认**：已落地，`start_import_wizard` 支持 stages 分阶段确认，按依赖顺序执行导入。

- 替换散落的 toISOString().slice(0,10) / split('T')[0] / replace('T',' ')（UTC 语义用 dayjs(...).utc() 保持完全一致）
- Asia/Shanghai 固定时区日期（Intl.DateTimeFormat en-CA）改用 dayjs().utcOffset(8)
- 月份边界 first/last、daysInMonth、nextMonth、shiftDate/addDays 等改 dayjs 简洁实现
- 涉及 attendance/classes/classrooms/room/dashboard/bills/expenses/occupancies/sync/ai-chat/rental 等 28 个文件

generateFromSchedules / getCalendar 原来用本地周一零点转 UTC 日期，
在上海时区会得到前一天的日期，导致默认范围变成周日~周日（8 天）。
改为 dayjs().utcOffset(8) 按中国日期计算，与 getTodayDateOnly 语义一致。

新增测试锁定：默认周 = 本周一~本周日，周日晚上仍归本周，显式传参原样透传。

joinDate/leaveDate/checkInDate/sync 起始日等业务日期默认值原来用
dayjs().utc()（UTC 今天），在国内 00:00-07:59 会取到昨天。
统一改为 dayjs().utcOffset(8)（固定 UTC+8 中国日期），与考勤周边界
修复保持一致；pending-tasks/controller-base 的本地 dayjs() 也显式化。

此前仅'今天'默认值统一为中国日期，Date→字符串的转换仍是 UTC：
- sync 考勤同步窗口 lastSyncAt 时间戳按 UTC 取日期，凌晨会偏一天
- 考勤导出 punchTime/createdAt 显示 UTC 时间
- normalizeDateOnly 把 ISO datetime 按 UTC 归一化，业务日期少一天
- getCourseClock/getChinaDateParts 用 dayjs.utc(date).add(8h) 隐式转换

统一为 dayjs(date).utcOffset(8)，纯日期字符串运算（shiftDate/addDays/
daysInMonth/nextMonth）保留 dayjs.utc；date-normalization 测试断言
同步更新为北京时间语义。

- 新增 queryKeys.ts 统一 QueryKey 工厂（覆盖全部模块，invalidate/refetch/prefetch 同源）
- 新增 queryClient.ts 全局配置：retry 1、staleTime 30s、gcTime 5min、refetchOnWindowFocus false
- 新增 useApiQuery：zod schema 校验 + 类型收敛 + select 转换，消除页面重复 validateResponse 样板
- useApiMutation 支持 onMutate/onSettled/context（乐观更新）
- 示范迁移：Organizations（useApiQuery + 乐观更新归档/恢复）、Students（useApiQuery + queryKeys + 打开抽屉前 prefetch 档案聚合）
- StudentProfileContent queryKey 统一为 queryKeys.archive.detail，prefetch 可命中缓存

+## apps/server/src/classes/classes.controller.ts（3）
+- **[security] L147-149** All mutation endpoints in this controller (update, archive, restore, remove, purge, batchImportStudents, addStudents, removeStudent, addTeacher, removeTeacher, removeTeacherAssignment) rely only on the global @RequirePermission('class:edit') and never call `await this.assertReadAccess(req, +id)`. The corresponding service methods (ClassesService.update/archive/purge/addStudents/addTeacher...) only perform existence checks, not membership checks. Since the read endpoints (findOne, getSchedule, getStudents, ...) do enforce assertReadAccess, a user who holds `class:edit` but is only assigned to some classes (e.g., a subject teacher) can modify, archive, purge, or import/remove students in ANY class — a broken-access-control / IDOR vulnerability. Add `await this.assertReadAccess(req, +id)` to every mutation endpoint, consistent with the read path.
+- **[security] L167-169** Destructive endpoint: purge permanently deletes a class, but unlike the read endpoints it never calls `assertReadAccess(req, +id)`, so any caller with the `class:purge`/`class:edit` permission can permanently delete a class they were never assigned to. Add `await this.assertReadAccess(req, +id)` before calling the service.
+- **[security] L127-129** Bulk import endpoint imports students (by DingTalk userId) into a class without any class-level access check — same missing `assertReadAccess(req, +id)` as the other mutation endpoints. A user with only `class:edit` can inject students into any class they are not assigned to.
+
+## deploy.sh（3）
+- **[bug] L34-39** Remote commands run without `set -e` (only the local shell enables `set -euo pipefail`). The ssh exit code is determined solely by the last remote command (`pm2 status`), so if `npm ci` or `npm run migration:run -w @gongxue/server` fails, the script still reloads PM2 and prints "部署完成！" — a failed migration is silently swallowed and the deploy is reported as successful. Add `set -euo pipefail` at the start of the remote command string (right after `cd ${REMOTE_DIR}`) or check each step's exit code explicitly.
+- **[security] L17-24** `--delete` will remove any server-only files that are not excluded. The repo contains no committed `.env` (only `.env.example`), so the production `.env` created manually on the server would be deleted on every deploy, and a local dev `.env` (if present) would overwrite the production one — leaking/erasing secrets. Add `--exclude='.env'` / `--exclude='.env.*'` and exclude any other server-only runtime data (e.g. `uploads/`) that must survive deploys.
+- **[bug] L30-33** `npm ci` runs only when `node_modules` does not exist on the server. On subsequent deploys, changes to `package.json`/`package-lock.json` (new or removed dependencies) are never installed because `node_modules` is excluded from rsync and already present remotely — production can run with stale dependencies while the local build (used to produce the deployed bundle) was built with new ones.

Either pass `req` through `getAccessibleClassIds(req)` (and have the service scope the queries) or restrict these routes to admins/super-admins explicitly.

Because class-validator requires all constraints on a property to pass, no value can ever satisfy both — every request using this DTO will be rejected with a 400. Pick one format: e.g. drop `strict: true` so `@IsISO8601()` accepts plain dates, or align the regex to the strict ISO format.

Declaring it as `number` lets TypeScript assume it is never null, defeating null-safety checks and risking NPEs/undefined behavior when accessing it. Declare it as `number | null`.

The server's `/attendance-records/alerts` endpoint (`getAlerts` in attendance-report.service.ts) returns items shaped `{ studentId, studentName, className, type, count, lastDate }` (and the admin `AlertItem` type also declares `studentNo`), but this schema requires `id` and `message`, which the API never returns. Since these fields are required in Zod, `validateResponse` will throw for every alert item and the alerts query will always fail at runtime.

+- **[bug] L77-82** This block mutates refs (commandsRef / idRef) during the render phase to detect a surfaceId change. This is a render-phase side effect: it violates React's rules and is unsafe under StrictMode double-rendering/concurrent rendering (an aborted render can leave the refs mutated while the committed output still belongs to the old surface). It also leaves the returned `commands` state out of sync: the refs are cleared but the `commands` state array is not reset, so consumers keep receiving the previous surface's commands until the next `pushCommands` call. Move the reset into an effect (and clear the state in sync), e.g.:

+## apps/admin/src/components/AiChat/DynamicChart.tsx（1）
+- **[bug] L204-208** The empty/undefined data guard runs *after* `useMemo` has already invoked `buildOption(chart)`. Every builder (`buildNameValueRows`, `buildCategoryOption`, etc.) immediately calls `chart.rows.map(...)` and `chart.columns[0]?.key`, so if `rows`/`columns` is missing at runtime this throws before the "暂无数据" placeholder is reached. The chart payload comes from AI message metadata that is only validated as `typeof payload === 'object'` (see `deriveCharts` in uiArtifacts.ts), so a missing `rows` array is entirely possible and the `!chart.rows` guard itself acknowledges it — the guard is just ineffective because of ordering. Fix: make the option build null-safe instead of moving the guard above the hook (that would violate the Rules of Hooks), e.g. only build the option when rows exist, and guard `columns` in the builders.
+  ```

This is inconsistent with `handlePreview` and `handleConnectionNext` error handling. Also, `res.log` may be undefined, so `res.log.message` can throw a TypeError that leaves the user without feedback. Handle the failure branch explicitly.

+- **[bug] L265-269** Pressing Enter while using editors whose value commits through their own internal Enter handling (`date`/`date-range`/`select`/`multi-select`/`tags`) will also hit this keydown handler and call `save()` with the `draft` captured in the current render. Those controls only update `draft` via their own async `onChange` (e.g., rc-picker commits a typed date, rc-select selects a highlighted option, tags mode adds a tag), so `draft` here is still the pre-interaction stale value. Depending on event ordering, `event.preventDefault()` may also suppress the control's commit — the user's typed date / selected option / typed tag is either silently discarded or the previous value gets saved over the new one (and two concurrent `onSave` calls can race). Restrict the Enter shortcut to editors whose draft is already in sync with the input (text/textarea/number/money).

Prefer forcing a download instead — e.g. build an `<a>` with a `download` attribute and click it, set the blob type to `application/octet-stream`, or serve the file through a dedicated endpoint returning `Content-Disposition: attachment` + `X-Content-Type-Options: nosniff`. Also note `window.open` may return null when blocked by popup blockers, and revoking the URL after a fixed 60s can break a preview tab that stays open longer.

+- **[bug] L9-12** `useMemo(readCurrentRoles, [])` reads the store only once at first render via `getState()` and never subscribes to updates. `userStore.user` is initialized as `null` and populated only after login/persist rehydration, so if this page mounts before the user data is available (or after role changes/logout), `roles` stays `[]` and `experience` is permanently stale — e.g. an academic admin (`教务管理员`) without an explicit `attendance:edit` permission would be wrongly routed to the teacher workspace. Use a zustand selector instead so the component subscribes and recomputes when roles change:

React then treats all editable cells as different component types and unmounts/remounts them on each render (e.g. when `loading`, `selectedKeys`, `data`, or filters change), which resets EditableCell's internal editing state (losing focus / unsaved input) and wastes reconciliation work across the whole table. Hoist this component to module scope and pass `permission`/`disabled` as props, or render cells via a plain function instead of JSX components.

+- **[bug] L80-82** The `useDirtyGuard` hook returns a freshly-created object literal `{ confirmClose, snapshot, isDirty }` on every render (see `useDirtyGuard.ts`). Because this entire object is in the effect's dependency array, this effect re-runs after *every* render of `ScheduleModal` while `open && mode !== 'detail'`, calling `scheduleGuard.snapshot()` each time. That resets the pristine baseline to the current form values, so the dirty-guard's `isDirty` check nearly always returns false and unsaved changes are silently discarded when closing the modal — the exact protection the guard is meant to provide. Since `snapshot` is memoized with `useCallback` and is stable, depend on it instead of the wrapper object.

The stored `session` values are English keys — `morning_reading`/`morning`/`afternoon`/`evening_study`/`night_check` (see `@IsIn` in attendance.dto.ts and `mapLessonScheduleTimeToSession` in attendance-time.ts) — but here the table columns are hardcoded Chinese labels `['上午','下午','晚自习']`. `cellMap` is keyed by `r.session`, so `cellMap.get(session)` never matches and every cell always shows `-`, silently dropping all detail data from the report. Additionally the system defines 5 session slots while only 3 columns are rendered. Suggest mapping the real session keys to display labels (covering all 5), e.g. build the columns from `{ morning_reading: '早读', morning: '上午', afternoon: '下午', evening_study: '晚自习', night_check: '晚查' }` or from the actual keys present in the records.

E.g. `2026-08-10` (Monday in China) becomes `2026-08-09T16:00Z` (Sunday) and this method returns `7` instead of `1`. As a result `getScheduleOptionsForAttendance` always queries the wrong `cs.weekDay` and returns schedules for the incorrect weekday.

If the timer fires while the original import is still genuinely running (which is the only case where it can fire, since `finally` always clears it on the normal path), it sets `isRunning = false` but does nothing to stop the hung import. A second import can then start concurrently, and both share the same `progressSubject` / `importingUserId`, so: (1) the old import's later `emit` calls get tagged with the new user's ID, breaking SSE scoping; (2) when the old import finally exits, its `finally` block resets `isRunning = false` and `importingUserId = undefined` while the new import is still running, allowing a third import to start. Consider using a per-run token/generation counter so only the matching run resets the flags, and refuse starting a new import until the previous run has truly finished.

Unlike `getDingRaw` (assertClassAccess) and `importFromDingTalk` (getTeacherClassDingUserIds), neither `matchDingRecord` nor `autoMatch` verifies that the raw record/student belongs to the requester's accessible classes. The underlying `AttendanceRecordMutationService.matchDingRecord` simply loads the record by id and saves the match, and `autoMatchDingRecords` iterates ALL unmatched records globally. A user holding only `attendance:edit` (e.g., a teacher) can match records belonging to other classes by guessing IDs and trigger a global auto-match. Suggest resolving the raw record's class and calling `assertClassAccess` before matching, and scoping `autoMatch` to the user's accessible classes (or requiring `canManageAllAttendance`).

Additionally, multiple sessions on the same day (morning/afternoon) are counted as separate days, and the lastDate update (`r.attendanceDate > current.lastDate`) never fires because the list is already sorted by date DESC. To correctly detect consecutive absences, group records per student per day (dedupe by date) and verify date difference === 1 day between consecutive entries.

It also silently degrades security instead of failing fast. Recommend removing the fallback and throwing when `JWT_SECRET` is absent (e.g., validate at startup), and ideally validating the secret length/strength. Same fallback also appears in jwt.strategy.ts and should be aligned.

Additionally this check-then-act (findOne followed by save/insert) is not atomic; two concurrent creates for the same new student can both pass the `!existing` branch and produce duplicate deposit rows.

+  ```
+    user.profile = { ...user.profile, ...profile };
+    await this.userRepo.save(user);
+    return { message: '资料已更新', profile: user.profile };

+## apps/server/src/rbac/rbac-seed.service.ts（1）
+- **[bug] L142-142** `seedData()` is invoked on every application startup (rbac.module.ts `onModuleInit`). This bulk UPDATE unconditionally re-activates ALL users with `isActive = false` on every boot, regardless of why they were disabled. Other code paths still write this field (e.g. `restoreUser` explicitly sets `isActive: true`), so any account set inactive — deliberately or by legacy/integration code — is silently re-enabled at the next restart. If this is meant as a one-time legacy migration, guard it with a migration/version flag or narrow the criteria so intentionally disabled accounts are not resurrected on every deploy.
+
+## apps/server/src/schedules/schedules.controller.ts（1）
+- **[security] L90-90** Authorization bypass: in schedules.service.ts, `findAll` only applies the `accessibleClassIds` restriction in the `else if` branch — when `query.classId` is provided, the accessible-class filter is skipped entirely. A teacher with only `schedule:view` can therefore pass an arbitrary `classId` and read schedules of classes they are not assigned to. Validate that `query.classId` is within the computed `classIds` here (and similarly for other handlers that forward a `classId` filter).
+  ```
+    if (query.classId !== undefined && classIds && !classIds.includes(query.classId)) {
+      return [];
+    }
+    return this.service.findAll(query, classIds);
+  ```
+
+## apps/server/src/students/students.import.service.ts（1）
+- **[bug] L44-48** `batchImport` performs multiple DB writes per row (existence check, student insert, archive imports) with no try/catch and no transaction. A single bad row (e.g., unique-constraint violation on studentNo/phone/idNumber, or an invalid archive row) aborts the entire import with a raw DB error, while rows already processed remain partially committed. Consider wrapping the import in a transaction and handling per-row errors (collect failures and continue) so one bad row doesn't discard the whole workbook.
+
+## apps/server/src/schedules/schedules.service.ts（1）
+- **[security] L103-104** Authorization bypass in `findAll`: when a caller supplies `query.classId`, the `accessibleClassIds` scope is skipped entirely (the `else if` branch never runs). The controller passes the teacher's accessible class IDs straight through without validating that `query.classId` belongs to the user, so a restricted teacher can list schedules of any class by passing its id — unlike `schedule-queries.service.ts` which rejects `classId` outside the accessible set. Enforce the intersection here, e.g. return `[]` when `accessibleClassIds` is defined and does not contain `query.classId`.
+  ```
+    if (query.classId) {
+      if (accessibleClassIds && !accessibleClassIds.includes(query.classId)) return [];
+      qb.andWhere('cs.classId = :classId', { classId: query.classId });
+    } else if (accessibleClassIds) {
+  ```
+
+## apps/server/src/sync/dto/schedule-sync.dto.ts（1）
+- **[bug] L6-8** Contradictory validation rules make `dateFrom` impossible to validate successfully. `@Matches(/^\d{4}-\d{2}-\d{2}$/)` only accepts a bare `YYYY-MM-DD` date, but `@IsISO8601({ strict: true })` (validator.js strict mode) requires a full ISO 8601 timestamp with the `T` separator, time portion, and optional timezone (e.g. `2026-08-09T00:00:00.000Z`). Since class-validator requires all constraints on a property to pass, no value can ever satisfy both — any request that includes `dateFrom` will be rejected with a 400, making the query parameter unusable. Fix by picking one format: drop `strict: true` so `@IsISO8601()` accepts plain dates, or align the regex to the strict ISO format.
+  ```
+  @Matches(/^\d{4}-\d{2}-\d{2}$/)
+  @IsISO8601()
+  dateFrom?: string;
+  ```
+
+## apps/server/src/students/students.service.ts（1）
+- **[security] L110-116** Authorization gap: unlike `findAll` and `getFilterLookups`, this method accepts no `accessibleClassIds` and the controller (`GET /students/basic-lookups`, permission `student:basic-view`/`student:view`) calls it without class scoping. As a result, any teacher who can view students gets every active student's PII (phone, studentNo, gender) across all classes — a horizontal privilege escalation inconsistent with the class-scoped behavior elsewhere in this file. Suggest accepting `accessibleClassIds` and filtering via `classStudentRepo` (same as `findAll`), or restricting this endpoint to manage-all users.
+  ```
+  async getBasicLookups(accessibleClassIds?: number[]) {
+    const where: FindOptionsWhere<Student> = { status: 'active' };
+    if (accessibleClassIds) {
+      const classStudents = await this.classStudentRepo.find({
+        where: { classId: In(accessibleClassIds), status: 'active' },
+      });
+      where.id = In([...new Set(classStudents.map((item) => item.studentId))]);
+    }
+    return this.repo.find({
+      select: ['id', 'name', 'studentNo', 'gender', 'phone', 'status'],
+      where,
+      order: { name: 'ASC' },
+    });
+  }
+  ```
+
+## apps/server/src/sync/schedule-sync.service.ts（1）
+- **[bug] L206-207** Attendance group name is derived only from className. If two different classes share the same name (very common in schools, e.g. "高一(1)班" in different grades/years), the second class will hit the group cached under the same name and `updateAttendanceGroup` will overwrite the group's members and shift_ids with the second class's data. The first class's already-written schedule items then point to a group whose members were replaced, corrupting attendance data. Unlike shift names, the group name has no period component to disambiguate. Suggest appending the classId: `排课_${className}_${classId}`.
+  ```
+      // 创建/匹配该班级的考勤组
+      const groupName = `排课_${className}_${classId}`;
+  ```
+
+## apps/server/src/sync/sync-runner.ts（1）
+- **[bug] L43-45** Errors thrown by `releaseLease` in the `finally` block will mask the original result: if the operation succeeded (and the log/state were updated) but releasing the lease fails (e.g. a transient DB error), the caller receives an exception for a fully successful sync, and the lease stays held until it goes stale. Wrap the release in a try/catch and only log the failure instead of rethrowing.
+  ```
+    } finally {
+      try {
+        await this.releaseLease(platform, runId);
+      } catch (releaseError) {

+## apps/server/src/sync/sync.service.ts（1）
+- **[bug] L223-225** When a Jinshuju entry has all mapped fields empty, `mappedValues` becomes `{}` and `manager.update(Student, decision.matchStudentId, {})` throws TypeORM's `UpdateValuesMissingError` ("Cannot perform update query because update values are not defined"), which rolls back the entire jinshuju sync transaction and fails the whole sync. Guard the update with a non-empty check (or skip the entry) before calling `update`.
+  ```
+          if (decision.action === 'match' && decision.matchStudentId) {
+            if (Object.keys(mappedValues).length > 0) {

+              matched++;
+            }
+  ```
+
+## apps/server/src/wallets/wallets.service.ts（1）
+- **[bug] L200-201** Concurrency / double-spend risk: `debitBill` (and `refundBill`/`settleOutstandingBills`) read `wallet.balance` with `getOrCreateWallet(manager, bill.studentId)` (lock defaults to false → plain `findOne`, no `FOR UPDATE`). External callers (`bills.service.ts`, `bills-generation.service.ts`) invoke `debitBill` inside their own transactions without ever locking the wallet row. In MySQL/InnoDB a plain SELECT is a non-blocking consistent read, so two concurrent debits for the same student (e.g. two bills generated in parallel, or a debit racing a wallet adjustment) can both read the same balance and both apply it → lost update / balance below zero / bill marked paid on money already spent. Since all callers pass a transactional `EntityManager`, read the wallet with `setLock('pessimistic_write')` (pass lock=true) in `debitBill`/`refundBill`, or use an atomic conditional update (`UPDATE student_wallets SET balance = balance - x WHERE student_id = ? AND balance >= x`).
+  ```
+    const wallet = await this.getOrCreateWallet(manager, bill.studentId, true);
+    const amount = money(Math.min(Math.max(0, money(wallet.balance)), remaining));

+## serve-proxy.js（1）
+- **[bug] L40-46** `API_TARGET` is read from the environment but never actually used — the proxy hardcodes `127.0.0.1:3000` (hostname, port, and host header are all hardcoded in three places). If `API_TARGET` points to a different host/port, requests are still forwarded to 127.0.0.1:3000, silently breaking the configuration. Parse the target once with `new URL(API_TARGET)` and derive hostname/port/host from it (note `http.request` also can't handle an `https://` target).

+# gongxue-base 修复记录（Phase 0-2 实施）
+
+> 依据 2026-08-09 OCR 全库审查（`all-comments.jsonl`，1626 条精确去重）与用户确认的计划（P0+P1，直接实施，允许 schema 变更）。
+> 执行：主 agent + 9 个并行 worker（按互不重叠的文件划分）。全部改动未提交，供人工 review。
+
+## 验证基线（最终）
+- server：`npm run typecheck` ✅ ｜ `npm run lint` ✅ 0 error 0 warning ｜ `jest` 148 套件 / 1087 用例 ✅
+- admin：`npm run typecheck` ✅ ｜ `vitest run` 33 文件 / 175 用例 ✅ ｜ `oxlint` 0 error（any 为 warn）
+- OCR 复查：全量改动 `ocr review` 1 轮（100 文件 / 84 条），定向 `ocr scan` 2 轮（12 文件 60 条 → 4 文件 18 条），发现的 critical/high 已逐条修复或明确降级为待办。
+

+- `oxlint.config.ts`：React 版本对齐实际安装（19.2.7）；`no-explicit-any` 改为 warn。
+
+## Phase 1 — 安全

+- 越权/IDOR：classes 全部变更接口补 `assertReadAccess`；dashboard 五个全局接口按班级范围收紧（非管理员返回空）；schedules.findAll 始终应用范围；students basic-lookups 范围化；attendance match 校验学生范围、auto-match 仅管理员；archive 全部路由按学生范围校验（新增 `resolveRecordStudentId` + `StudentsService.assertStudentAccess`）；exams 权限码尝试分离后因 `exam:create/edit/delete` 属废弃码**回滚**为 `exam:view`（服务层已有范围校验，见待办）。
+- 全局 `ValidationPipe({ transform: true })`（不开 whitelist，避免裸 body 被剥空）。
+- 凭据：集成配置 appSecret 复用 AES-256-GCM 静态加密（`secret-crypto.ts` + 回填脚本 `npm run encrypt:integration-secrets`）；对外输出脱敏。
+- 注入：`common/like-escape.ts` + 13 处 LIKE 调用转义（含 rbac 教师搜索）。
+- 无界输入：attendance records `@ArrayMaxSize(500)`、ai-chat values ≤200 字段、notes `@MaxLength(1000)`、sync limit ≤200、全部上传 10MB 上限。
+- 上传/下载/XSS：`common/mime.ts` 扩展名白名单归一化 + `X-Content-Type-Options: nosniff` + 安全类型才 inline；上传判空 400；流 error/close 处理；`AttachmentsTab` 不再 window.open(blobURL)（img/sandbox iframe/<a download> + revoke）。
+- 其他：`request-utils` 默认不信任代理头（`TRUST_PROXY=1` 才信任）；`updateTeacherProfile` 返回脱敏；`.env.example` 补充 TRUST_PROXY 说明。
+
+## Phase 2 — 数据正确性

+- 实体：learning-record / student-profile 的 student_id 双映射移除；student-wallet / bill 金额 DECIMAL 加 number transformer；ding-leave/attendance-raw 可空 FK 类型 `| null`；class-student 外键 onDelete 统一 CASCADE；`app.module` synchronize 仅显式 true。
+- 时区：`common/china-time.ts`（getChinaDate / addDaysToDateOnly / getWeekDayFromDateOnly / isConsecutiveDates + 单测）；attendance-calendar、ai-review.import-basic、attendance-generation、rental-schedule 的本地/UTC 混用修复。
+- 状态/路由：bills batch/status 与 classrooms report 路由顺序；attendance-report 连续日真实判断；sync 空 mappedValues 跳过更新；考勤组名带 classId；rbac-seed 仅空表或 `SEED_ROLES=true` 播种 + 默认管理员仍会创建（生产缺 ADMIN_PASSWORD 报错、不打印密码、不再批量重激活禁用用户、删除死代码）；expense-types 唯一性检查回滚为与 DB 唯一索引一致；agent-tool.registry 重复注册守卫。
+- 前端：Roles 多组勾选受控化；Schedules 月视图可新建；useDirtyGuard 返回稳定引用；JinshujuMatchModal success:false 分支；Attendance 订阅 store；late 计入出勤率/主状态；EditableCell Enter 不再与 select/date 编辑器冲突；DynamicChart 空数据短路；useSubmissionState ref 变更移到 layout effect。
+
+## 追加修复（2026-08-09 第二轮）
+- **exams 写权限分离**：`exam:create/exam:edit/exam:delete` 从 `DEPRECATED_PERMISSION_CODES` 移除并加入 `PRESET_PERMISSIONS`（seed 会创建）；控制器 create→`exam:create`，archive/restore/batch-*/updateScore→`exam:edit`，purge→`exam:purge`；spec 同步（新增 4 组权限断言）。
+- **wallets refundBill 幂等**：退款前对账单做条件更新 `status <> 'cancelled'`（affected=0 直接返回），与 bills.cancel 的事务悲观锁双保险，杜绝并发重复冲正。
+- **exams updateScore 防误清空**：`score` 缺失（undefined）直接 400，清空必须显式传 null。
+- 验证：server typecheck/lint ✅，jest 148 套件 / 1091 用例 ✅；定向 OCR 复查 3 文件无 high/critical。
+
+## 持续修复循环（Round 1-7，OCR 复查驱动）
+
+> 按用户要求启动持续修复+review goal：每轮并行派发 3 个互不重叠的 worker → 全量验证 → OCR 定向复查 → 再修，共 7 轮。
+
+- **R1（medium 清理）**：deploy SSH_HOST 校验/密钥 heredoc、jwt-secret 环境判定、encrypt 脚本防回退密钥+连接释放、archive 下载审计、bills 通知 catch；rbac 密码 8-72、attendance-import success/release、wallets 分页、attendance 日期边界/连续段语义、AttachmentsTab 乱序、serve-proxy 尾斜杠；migrate trap/防重入/就绪检查、rental ENDED、students.import 死注入、bills-generation 注释。
+- **R2（high 修复）**：archive 死代码、rental 死循环×2、financial SQL 优先级、wallets :amount 绑定、exams 权限回滚+spec、rbac-seed admin 创建、attendance 看门狗语义、serve-proxy fallback MIME、migrate argv、deploy npm ci、expense-types 一致性。
+- **R3（exams 权限 + wallets 幂等）**：exam:create/edit 从废弃列表恢复并 seed、控制器按写操作标注；refundBill 条件更新幂等；updateScore 空 PUT 防护。定向复查 3 文件 0 high。
+- **R4（medium 批量）**：bills 通知/ids、jwt-secret、encrypt 脚本、archive 审计、attendance success/release/日期/连续段、AttachmentsTab 序号、serve-proxy、migrate trap/flock、rental ENDED、students.import 死注入、rbac.dto 校验。
+- **R5（4 high + quick wins）**：migrate cd/TOCTOU、jwt SEED_DEV、students.import 空 updates、bills 首次生成并发（GET_LOCK）；serve-proxy 超时竞态/非法头/请求头 hop-by-hop/URL 回退；attendance-generation N+1、matchImport 事务、锁名常量、rbac.dto 校验、bills 批量学生+allSettled。
+- **R6（high→1 + quick）**：attendance 看门狗只告警、runner.connect try/finally、fetchAllPages 并发、mapToEntity 批量预取；attendance-generation 标签/死代码/事务；bills 批量保存/四舍五入/未用注入；rental 多日展开+事务+枚举；students.import host org 缓存/日期日历校验；rbac.dto 锚定正则+长度上限。
+- **R7（high→0）**：bills 路由顺序（export 在 :id 前）+ ids DTO；serve-proxy 失败分支 error 监听/写头抛错释放 socket/客户端断开；migrate DUMP 绝对路径/原子锁/文件预检/APP_STARTED/5 表就绪/DML-only 说明；rbac.dto 显示名允许内部空格+密码字节上限+subjects 唯一性；bills 通知幂等（仅新增 paid 才发）+ reason 审计转义（本轮新增）。
+
+### 收敛结论
+- 连续 2 轮 OCR 定向复查（覆盖所有修复过的文件）：**high/critical = 0**。
+- 每轮全量验证：server `typecheck` ✅ `lint` 0 error ✅ `jest` **152 套件 / 1170 用例** ✅；admin `typecheck` ✅ `vitest` 175 ✅。
+- 剩余为 **P2 性能/重构/依赖 schema** 项（见下），非本轮目标。
+### 收尾补充（复查核对后）
+- `bills.controller`：取消账单的 `reason` 写入审计日志前做控制字符过滤（防日志注入）。
+- `serve-proxy`：删除 serveStatic 未使用的 `req` 参数。
+- `migrate.sh`：就绪检查超时时输出期间收集的 MySQL stderr（密码错误/容器未启动可诊断）。
+- 验证：server lint/typecheck/jest 152 套件 / 1170 用例全绿。
+
+## P2 纯代码项（并行 3 worker + 复查二修）
+- **serve-proxy 静态流式化**：fs.stat + Content-Length + createReadStream pipe，消除全量缓冲；目录请求 404、realpath 防 symlink 穿越。
+- **migrate.sh 库名变量化**：LEGACY_DB/TARGET_DB 抽变量；COMMIT 用 printf 防粘行；IMPORTED_COUNT 失败兜底；`.migrate.done` 改为数据提交后立即写。
+- **attendance-import**：IN(dingIds) 按 1000 分块并发查询；finally 仅抢到锁才清理运行态。
+- **students.import**：phone/idNumber 批量预取（2 条 IN 查询）替代逐行 findOne；新增双键冲突检测（phone/idNumber 命中不同学生 → 跳过并计 skippedConflict，防数据错乱）。
+- **bills-generation**：per-room 入住查询改为一次 IN 批量 + 内存分组；日期统一 YYYY-MM-DD 字符串比较（toDateOnly/daysBetweenDateOnly），消除 Date hydrate 比较不可靠；eligibleDays 提出循环。
+- **bills DTO**：BatchIdsBodyDto 移入 dto/bill.dto；batchPurge/batchRemove 复用 common BatchIdsDto；billingMonth 收紧为真实月份。
+- **rbac.dto**：UpdateRoleDto/UpdateUserDto 用 PartialType/OmitType 去重；subjects 补非空白 each。
+- 复查二修：serve-proxy 目录/realpath、matchImport 冲突、bills 日期、attendance finally、DTO/migrate 小项；spec 同步。
+- 验证：server typecheck/lint 全绿，jest **152 套件 / 1178 用例** ✅。
+
+## 剩余（已收敛）
+- 数据库唯一约束（bills 周期、Student.phone/idNumber、expense-type code 放开软删复用）与迁移文件生成（class_student 外键 CASCADE）——需接库环境执行 `npm run migration:generate -- FixEntityMappings`。
+- 少量 low（STATIC_DIR 可配置、%20 解码、X-Forwarded 链保留、登录时序侧信道权衡项等）按需处理。
+- 迁移文件生成（class_student 外键 CASCADE 等）：`cd apps/server && npm run migration:generate -- FixEntityMappings`（需接库环境）。
+- 低价值 low 项（如 STATIC_DIR 可配置、%20 解码、x-forwarded 链保留、attendance-import 无界 IN 分块等）按需后续处理。
+
+## 待办/已知（未修）
+1. ~~exams 写权限分离~~ ✅ 已修复（见追加修复）。
+2. ~~wallets refund 的 bill 状态 check-then-act~~ ✅ 已修复（条件更新幂等）。
+3. **迁移文件**：实体改动（class_student 外键 CASCADE 等）需在接库环境 `cd apps/server && npm run migration:generate -- FixEntityMappings` 生成并 review 后上线；本地无 MySQL 未生成。
+4. **P2 backlog**：剩余 low/维护性 ~700 条（见 `all-comments.jsonl`），未在本轮实施。
+5. OCR 复查仍提示的 medium/low（如 migrate.sh 无并发锁/命令注入面、rbac-seed N+1、serve-proxy 的 servedIndex 冗余等）可按后续迭代处理。

+## 部署/运维高危问题（根级文件）
+
+1. **`serve-proxy.js`**：`API_TARGET` 环境变量被读取但从未使用，硬编码 `127.0.0.1:3000`；catch-all 对所有缺失文件返回 index.html(200)，掩盖资源缺失；`readFileSync` 阻塞事件循环；透传 hop-by-hop 头。
+2. **`migrate.sh`**：明文/硬编码数据库密码、固定 `sleep 8` 竞态、SQL 无事务（部分迁移）、无 trap 清理。
+3. **`deploy.sh` + `.gitea/workflows/deploy.yml`**：`rsync --delete` 可能删掉服务器端 `.env`；`npm ci` 被 node_modules 存在性跳过导致新依赖永不安装；远程命令块无 `set -e`，失败仍 reload PM2 且退出码 0；workflow 无 concurrency 并发控制。
+4. **`ecosystem.config.cjs`**：缺 `kill_timeout`（SIGKILL 约 1.6s 后强杀，请求/DB 连接被切断）；相对日志路径按启动目录解析。
+5. **`oxlint.config.ts`**：React 硬编码 `19.0.0`（仓库无对应依赖）；全局禁用 `no-explicit-any`。
+
+## 后端（server）突出问题主题
+
+- **认证/授权**：登录失败锁定可被永久锁定、用户名枚举、密码策略过弱（最短 4 位无上限）、JWT/审计相关风险。
+- **SQL LIKE 通配符未转义**：`%`/`_` 可扩大搜索范围（classes/students/deposits/rooms 等多个 service）。
+- **DTO 校验矛盾**：`@Matches` + `@IsISO8601({strict:true})` 同时存在导致任何值都无法通过（dashboard-query/schedule-sync/occupancy dto）。
+- **非原子多步写入**：imports/rooms/students/exams/attendance 多处无事务，失败留半截状态。
+- **审计/副作用写入在请求路径中可导致操作失败**（with-audit-log、auth.controller 等）。
+- **check-then-act 竞态**：ai-chat.conversations、ai-form.service、classroom-rentals.service、attendance-leave-sync 等。
+- **N+1 / 循环内顺序 await**：attendance-import、bills、dashboard-queries、archive-report 等。
+- **无界输入**：records 数组、values、密码、notes、page/limit 无上限。
+- **时区混用**：本地时间与 UTC+8 混用（约 8 处重复模式），`common/dayjs.ts` 注释声称引入 tz 插件但实际没有。
+
+## 前端（admin）突出问题主题
+
+- **A11y**：`.ai-chat-hover-actions` opacity:0 但仍在 Tab 序中；`:focus-visible` 被移除；可编辑单元格无焦点样式；对比度不足（#ff4d4f）。
+- **crypto.randomUUID() 无降级**：provider.ts、operation-id.ts、LiteMermaid.tsx、EditableCell/index.tsx 在非安全上下文会抛错。
+- **错误处理反模式**：空 catch、unhandled promise rejection（prefetchQuery、validateFields）、成功提示实际失败、catch 范围过大。
+- **渲染期写 ref / 缺 cleanup**：useSubmissionState、usePageVisible、DynamicReview、ECharts 等 8 处。
+- **重复逻辑**：useLockerMutations≈useBedMutations、persist.ts 3 个 migrate、message-mappers 4 个 history 提取等。
+- **严格相等规则违反**：schedule-visibility.ts、DepositModals.tsx、AiChatDrawer.tsx 的 `==`/`!=`。
+- **跨字段校验缺失**：日期区间倒置、跨零点课表、金额符号未与操作类型绑定、whitespace-only required。
+
+## 快速修复清单（Quick Wins 摘选）
+
+1. **LIKE 通配符转义**：classes/students/deposits/rooms 的 `Like("%"+keyword+"%")` 加转义 helper。
+2. **上传空文件防护**：archive/expenses/classrooms/rooms/occupancies/students/imports 控制器对 `@UploadedFile()` 加 null 判断，500→400。
+3. **修复矛盾校验器**：`@Matches`+`@IsISO8601({strict:true})` 二选一（3 个 dto）。
+4. **加输入上限**：deposits.studentIds、notifications dto、bed/locker count、sync limit 等。
+5. **替换废弃 `findByIds`**：ai-attachment.service、rbac-user.service 改用 `In(ids)`。
+6. **fire-and-forget 通知 promise 补 await/.catch**：bills/deposits/occupancies controller。
+7. **审计日志 best-effort**：with-audit-log 及日志后置控制器，避免成功操作被日志拖成 500。
+8. **部署面**：deploy 加 `--exclude=.env*`、固定跑 npm ci、远程块 `set -e`、workflow 加 concurrency、PM2 `kill_timeout:5000`、serve-proxy 用 `API_TARGET` 并改流式读文件。
+9. **时区统一**：抽 `CHINA_TZ`/`CN_UTC_OFFSET=8` 常量替换约 8 处重复的 UTC+8 逻辑。
+10. **oxlint**：React `version: "detect"`，去掉全局 no-explicit-any，改为定点禁用。

由 OCR（open-codereview.ai，deepseek-v4-flash）审查驱动修复：
- classrooms.controller：report 路由移到 :id 之前、上传 10MB + 判空
- classrooms.service：搜索关键词 LIKE 通配符转义
