+# P2 Remaining Tasks Implementation Plan
+
+> **For agentic workers:** Use superpowers:subagent-driven-development (recommended) to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Complete the 4 genuinely remaining P2 items: dashboard classroom utilization stats, list page filter enhancements, deposit refund approval workflow, and scheduled sync implementation.
+
+**Architecture:** Backend enhancements (UtilizationStats endpoint, deposit refund workflow status transitions, sync stubs → real API calls) plus frontend enhancements (dashboard utilization section, list page filter bars).
+
+**Tech Stack:** NestJS 11 + TypeORM 0.3 (backend), React 19 + Ant Design 6 + ECharts (frontend), SQLite/MySQL, @nestjs/schedule (Cron).
+
+## Global Constraints
+
+- All list pages ≥ 50 records MUST have comprehensive filter bars (class, date range, status, source, etc.)
+- Sensitive operations (refund approval) MUST log via OperationLogsService
+- Follow existing NestJS module structure
+- Dashboard stats MUST respect CampusScope data isolation
+
+---
+
+### Task 1: Dashboard — Classroom Utilization Section
+
+**Files:**
+- Modify: `apps/server/src/dashboard/dashboard.service.ts` (add `getClassroomUtilizationStats()`)
+- Modify: `apps/server/src/dashboard/dashboard.controller.ts` (add `GET /dashboard/classroom-utilization`)
+- Modify: `apps/admin/src/pages/Dashboard/index.tsx` (add utilization section below existing charts)
+
+**Interfaces:**
+- Consumes: `Classroom`, `ClassSchedule`, `ClassroomRental` repos already injected
+- Produces: `getClassroomUtilizationStats(): Promise<UtilizationStats>` where `UtilizationStats = { totalClassrooms: number; inUseCount: number; utilizationRate: string; scheduleHours: number; rentalDays: number }`
+
+- [ ] **Step 1: Add `getClassroomUtilizationStats()` method to DashboardService**
+
+```typescript
+// apps/server/src/dashboard/dashboard.service.ts — add after getClassroomOccupancy()
+
+async getClassroomUtilizationStats() {
+  const scopeIds = await this.scope.getScopeDepartmentIds();
+  const totalClassrooms = await this.classroomRepo.count({
+    where: await this.scope.filter({ status: Not('archived') }),
+  });
+
+  const today = new Date().toISOString().slice(0, 10);
+
+  // Count classrooms with active schedules today
+  const schedQb = this.scheduleRepo
+    .createQueryBuilder('s')
+    .select('COUNT(DISTINCT s.classroomId)', 'cnt')
+    .where('s.status = :active', { active: 'active' })
+    .andWhere('s.scheduleType = :type', { type: 'INTERNAL' })
+    .andWhere('s.startDate <= :today AND s.endDate >= :today', { today });
+  if (scopeIds) schedQb.andWhere('s.departmentId IN (:...scopeIds)', { scopeIds });
+  const schedResult = await schedQb.getRawOne();
+
+  // Count classrooms with active rentals today
+  const rentalQb = this.rentalRepo
+    .createQueryBuilder('r')
+    .select('COUNT(DISTINCT r.classroomId)', 'cnt')
+    .where('r.status != :cancelled', { cancelled: 'cancelled' })
+    .andWhere('r.startDate <= :today AND r.endDate >= :today', { today });
+  if (scopeIds) rentalQb.andWhere('r.departmentId IN (:...scopeIds)', { scopeIds });
+  const rentalResult = await rentalQb.getRawOne();
+
+  // Combine: use Set merge of both
+  const combinedQb = this.scheduleRepo
+    .createQueryBuilder('s')
+    .select('s.classroomId')
+    .where('s.status = :active', { active: 'active' })
+    .andWhere('s.scheduleType = :type', { type: 'INTERNAL' })
+    .andWhere('s.startDate <= :today AND s.endDate >= :today', { today })
+    .groupBy('s.classroomId');
+  if (scopeIds) combinedQb.andWhere('s.departmentId IN (:...scopeIds)', { scopeIds });
+  const schedIds = await combinedQb.getRawMany();
+
+  const combinedRentalQb = this.rentalRepo
+    .createQueryBuilder('r')
+    .select('r.classroomId')
+    .where('r.status != :cancelled', { cancelled: 'cancelled' })
+    .andWhere('r.startDate <= :today AND r.endDate >= :today', { today })
+    .groupBy('r.classroomId');
+  if (scopeIds) combinedRentalQb.andWhere('r.departmentId IN (:...scopeIds)', { scopeIds });
+  const rentalIds = await combinedRentalQb.getRawMany();
+
+  const allInUseIds = new Set([
+    ...schedIds.map((s: any) => s.classroomId),
+    ...rentalIds.map((r: any) => r.classroomId),
+  ]);
+
+  const scheduleCount = parseInt(schedResult?.cnt || '0', 10);
+  const rentalCount = parseInt(rentalResult?.cnt || '0', 10);
+  const inUseCount = allInUseIds.size;
+  const utilizationRate = totalClassrooms > 0
+    ? ((inUseCount / totalClassrooms) * 100).toFixed(1)
+    : '0';
+
+  return {
+    totalClassrooms,
+    inUseCount,
+    utilizationRate,
+    scheduleCount,
+    rentalCount,
+  };
+}
+```
+
+- [ ] **Step 2: Add controller endpoint**
+
+```typescript
+// apps/server/src/dashboard/dashboard.controller.ts — add inside DashboardController
+
+@Get('classroom-utilization')
+async getClassroomUtilization() {
+  return this.service.getClassroomUtilizationStats();
+}
+```
+
+- [ ] **Step 3: Add utilization section to Dashboard frontend**
+
+Add after the existing stats cards row and classroom occupancy chart section in `apps/admin/src/pages/Dashboard/index.tsx`:
+
+```typescript
+// Add state
+const [classroomUtil, setClassroomUtil] = useState<{
+  totalClassrooms: number;
+  inUseCount: number;
+  utilizationRate: string;
+  scheduleCount: number;
+  rentalCount: number;
+} | null>(null);
+
+// Add fetch in fetchData
+const cu = await api.get('/dashboard/classroom-utilization');
+setClassroomUtil(cu);
+
+// Add a Card row after existing stat cards
+<Card title="教室利用率" style={{ marginBottom: 16 }}>
+  <Row gutter={[24, 16]}>
+    <Col xs={12} sm={6}>
+      <Statistic title="教室总数" value={classroomUtil?.totalClassrooms ?? '-'} prefix={<ReadOutlined />} />
+    </Col>
+    <Col xs={12} sm={6}>
+      <Statistic title="今日使用" value={classroomUtil?.inUseCount ?? '-'} prefix={<CheckCircleOutlined />} />
+    </Col>
+    <Col xs={12} sm={6}>
+      <Statistic
+        title="利用率"
+        value={classroomUtil?.utilizationRate ?? '-'}
+        suffix="%"
+        prefix={<PercentageOutlined />}
+        valueStyle={{ color: Number(classroomUtil?.utilizationRate ?? 0) > 70 ? '#34C759' : '#FF9500' }}
+      />
+    </Col>
+    <Col xs={12} sm={6}>
+      <Statistic title="内部排课" value={classroomUtil?.scheduleCount ?? '-'} prefix={<CalendarOutlined />} />
+    </Col>
+  </Row>
+</Card>
+```
+
+- [ ] **Step 4: Verify**
+
+Run: `cd apps/server && npx jest --testPathPattern="dashboard" 2>/dev/null || echo "no tests yet"`
+Start dev server, open dashboard, confirm utilization section renders with correct data.

+
+### Task 2: Deposit Refund Approval Workflow
+
+**Files:**
+- Modify: `apps/server/src/entities/deposit.entity.ts` (add `refundStatus`, `refundRequestedAt`, `refundApprovedBy`, `refundApprovedAt`, `refundRejectedReason`)
+- Modify: `apps/server/src/deposits/deposits.service.ts` (add `requestRefund`, `approveRefund`, `rejectRefund` methods)
+- Modify: `apps/server/src/deposits/deposits.controller.ts` (add endpoints)
+- Modify: `apps/server/src/deposits/dto/deposit.dto.ts` (add DTOs)
+- Modify: `apps/admin/src/pages/Deposits/index.tsx` (add approval UI)
+
+**Interfaces:**
+- Produces: `POST /deposits/:id/request-refund`, `PUT /deposits/:id/approve-refund`, `PUT /deposits/:id/reject-refund`
+
+- [ ] **Step 1: Add refund workflow fields to Deposit entity**
+
+```typescript
+// apps/server/src/entities/deposit.entity.ts — add fields inside Deposit class
+
+@Column({ name: 'refund_status', length: 20, nullable: true })
+refundStatus: string; // 'pending_approval' | 'approved' | 'rejected'
+
+@Column({ name: 'refund_requested_at', type: 'datetime', nullable: true })
+refundRequestedAt: Date;
+
+@Column({ name: 'refund_approved_by', type: 'integer', nullable: true })
+refundApprovedBy: number;
+
+@Column({ name: 'refund_approved_at', type: 'datetime', nullable: true })
+refundApprovedAt: Date;
+
+@Column({ name: 'refund_rejected_reason', length: 500, nullable: true })
+refundRejectedReason: string;
+```
+
+- [ ] **Step 2: Add DTOs**
+
+```typescript
+// apps/server/src/deposits/dto/deposit.dto.ts — add exports
+
+export class RequestRefundDto {
+  @IsOptional()
+  @IsString()
+  reason?: string;
+}
+
+export class ApproveRefundDto {
+  @IsNumber()
+  approvedBy: number;
+}
+
+export class RejectRefundDto {
+  @IsString()
+  @IsNotEmpty()
+  reason: string;
+
+  @IsNumber()
+  rejectedBy: number;
+}
+```
+
+- [ ] **Step 3: Add service methods**
+
+```typescript
+// apps/server/src/deposits/deposits.service.ts — add methods
+
+async requestRefund(id: number) {
+  const deposit = await this.repo.findOne({ where: { id } });
+  if (!deposit) throw new NotFoundException('押金记录不存在');
+  if (deposit.refundStatus === 'pending_approval') {
+    throw new BadRequestException('该押金已提交退还申请，等待审批中');
+  }
+  if (deposit.refundStatus === 'approved') {
+    throw new BadRequestException('该押金已通过审批');
+  }
+  deposit.refundStatus = 'pending_approval';
+  deposit.refundRequestedAt = new Date();
+  return this.repo.save(deposit);
+}
+
+async approveRefund(id: number, approvedBy: number) {
+  const deposit = await this.repo.findOne({ where: { id } });
+  if (!deposit) throw new NotFoundException('押金记录不存在');
+  if (deposit.refundStatus !== 'pending_approval') {
+    throw new BadRequestException('该押金不在待审批状态');
+  }
+  deposit.refundStatus = 'approved';
+  deposit.refundApprovedBy = approvedBy;
+  deposit.refundApprovedAt = new Date();
+  return this.repo.save(deposit);
+}
+
+async rejectRefund(id: number, reason: string, rejectedBy: number) {
+  const deposit = await this.repo.findOne({ where: { id } });
+  if (!deposit) throw new NotFoundException('押金记录不存在');
+  if (deposit.refundStatus !== 'pending_approval') {
+    throw new BadRequestException('该押金不在待审批状态');
+  }
+  deposit.refundStatus = 'rejected';
+  deposit.refundApprovedBy = rejectedBy;
+  deposit.refundApprovedAt = new Date();
+  deposit.refundRejectedReason = reason;
+  return this.repo.save(deposit);
+}
+```
+
+- [ ] **Step 4: Add controller endpoints**
+
+```typescript
+// apps/server/src/deposits/deposits.controller.ts — add endpoints
+
+@Post(':id/request-refund')
+@RequirePermission('deposit:edit')
+async requestRefund(@Param('id') id: string, @Request() req: any) {
+  const { ipAddress, userAgent } = extractRequestInfo(req);
+  const result = await this.service.requestRefund(+id);
+  await this.logService.log({
+    userId: req.user?.id,
+    username: req.user?.username,
+    module: '押金管理',
+    action: '申请退还',
+    targetId: +id,
+    targetType: 'deposit',
+    detail: `申请押金退还`,
+    ipAddress,
+    userAgent,
+  });
+  return result;
+}
+
+@Put(':id/approve-refund')
+@RequirePermission('deposit:edit')
+async approveRefund(@Param('id') id: string, @Request() req: any) {
+  const { ipAddress, userAgent } = extractRequestInfo(req);
+  const result = await this.service.approveRefund(+id, req.user?.id);
+  await this.logService.log({
+    userId: req.user?.id,
+    username: req.user?.username,
+    module: '押金管理',
+    action: '通过退还审批',
+    targetId: +id,
+    targetType: 'deposit',
+    ipAddress,
+    userAgent,
+  });
+  return result;
+}
+
+@Put(':id/reject-refund')
+@RequirePermission('deposit:edit')
+async rejectRefund(
+  @Param('id') id: string,
+  @Body() body: { reason: string },
+  @Request() req: any,
+) {
+  const { ipAddress, userAgent } = extractRequestInfo(req);
+  const result = await this.service.rejectRefund(+id, body.reason, req.user?.id);
+  await this.logService.log({
+    userId: req.user?.id,
+    username: req.user?.username,
+    module: '押金管理',
+    action: '驳回退还申请',
+    targetId: +id,
+    targetType: 'deposit',
+    detail: `驳回原因：${body.reason}`,
+    ipAddress,
+    userAgent,
+  });
+  return result;
+}
+```
+
+- [ ] **Step 5: Add frontend approval UI**
+
+Modify `apps/admin/src/pages/Deposits/index.tsx` — in the deposits table, add a refund status column and action buttons:
+
+- Add column: `refundStatus` with Tag rendering (pending_approval=orange '待审批', approved=green '已通过', rejected=red '已驳回')
+- Add action button "申请退还" (when refundStatus is null and not yet refunded)
+- Add action buttons "通过"/"驳回" (when refundStatus === 'pending_approval')
+
+```typescript
+// In columns array, add:
+{
+  title: '退还状态',
+  dataIndex: 'refundStatus',
+  key: 'refundStatus',
+  width: 100,
+  render: (v: string) => {
+    const m: Record<string, { text: string; color: string }> = {
+      pending_approval: { text: '待审批', color: 'orange' },
+      approved: { text: '已通过', color: 'green' },
+      rejected: { text: '已驳回', color: 'red' },
+    };
+    const item = m[v];
+    return item ? <Tag color={item.color}>{item.text}</Tag> : v || '-';
+  },
+},
+// In action column, add conditional buttons:
+{record.refundStatus === 'pending_approval' && (
+  <>
+    <Popconfirm title="确认通过？" onConfirm={() => handleApproveRefund(record.id)}>
+      <Button size="small" type="link" style={{ color: '#34C759' }}>通过</Button>
+    </Popconfirm>
+    <Button size="small" type="link" danger onClick={() => {
+      setRejectTarget(record);
+      setRejectModalOpen(true);
+    }}>驳回</Button>
+  </>
+)}
+{!record.refundStatus && !record.refundedAt && (
+  <Popconfirm title="确认提交退还申请？" onConfirm={() => handleRequestRefund(record.id)}>
+    <Button size="small" type="link">申请退还</Button>
+  </Popconfirm>
+)}
+```
+
+- [ ] **Step 6: Add reject reason modal**
+
+```typescript
+// State
+const [rejectModalOpen, setRejectModalOpen] = useState(false);
+const [rejectTarget, setRejectTarget] = useState<any>(null);
+const [rejectReason, setRejectReason] = useState('');
+
+// Handler
+const handleRejectRefund = async () => {
+  await api.put(`/deposits/${rejectTarget.id}/reject-refund`, { reason: rejectReason });
+  message.success('已驳回');
+  setRejectModalOpen(false);
+  setRejectReason('');
+  fetchData();
+};
+
+// Modal
+<Modal
+  title="驳回退还申请"
+  open={rejectModalOpen}
+  onOk={handleRejectRefund}
+  onCancel={() => setRejectModalOpen(false)}
+>
+  <Input.TextArea
+    placeholder="请输入驳回原因"
+    value={rejectReason}
+    onChange={(e) => setRejectReason(e.target.value)}
+    rows={3}
+  />
+</Modal>
+```
+

+
+### Task 3: Student Archive — Multi-Enrollment Comparison View
+
+**Files:**
+- Modify: `apps/admin/src/pages/Students/*` (add comparison view toggle to student detail)
+- Create: no new files; enhance existing Student detail view
+
+**Interfaces:**
+- Consumes: Existing `student_enrollments` data from student API response (already returns enrollments in detail view)
+- Produces: Side-by-side comparison cards for culture vs professional enrollments
+
+- [ ] **Step 1: Add enrollment comparison component to Students page**
+
+The student detail modal/expand already fetches enrollments. Add a comparison section when a student has 2+ enrollments:
+
+```typescript
+// In the student detail modal (or table expanded row), after basic info:
+{student.enrollments && student.enrollments.length >= 2 && (
+  <Card title="多班型对比" size="small" style={{ marginTop: 16 }}>
+    <Row gutter={16}>
+      {student.enrollments.map((enr: any, idx: number) => (
+        <Col span={12} key={enr.id}>
+          <Card
+            size="small"
+            title={enr.classType || `班型 ${idx + 1}`}
+            style={{ background: idx === 0 ? '#f0f5ff' : '#f6ffed' }}
+          >
+            <Descriptions column={1} size="small">
+              <Descriptions.Item label="班级">{enr.className || '-'}</Descriptions.Item>
+              <Descriptions.Item label="课程类别">{enr.courseCategory || '-'}</Descriptions.Item>
+              <Descriptions.Item label="开班日期">{enr.startDate || '-'}</Descriptions.Item>
+              <Descriptions.Item label="结课日期">{enr.endDate || '-'}</Descriptions.Item>
+              <Descriptions.Item label="班主任">{enr.headTeacher || '-'}</Descriptions.Item>
+              <Descriptions.Item label="任课教师">{enr.teacher || '-'}</Descriptions.Item>
+            </Descriptions>
+          </Card>
+        </Col>
+      ))}
+    </Row>
+  </Card>
+)}
+```
+
+- [ ] **Step 2: Verify**
+
+Open Students page, click on a student with multiple enrollments. Confirm comparison cards render side-by-side.
+
+---
+
+### Task 4: Scheduled Sync — Fill Integration Stubs
+
+**Files:**
+- Modify: `apps/server/src/sync/sync.service.ts` (implement `performDingTalkSync` and `performWeComSync`)
+- Modify: `apps/server/src/sync/sync.controller.ts` (add sync status endpoint if not present)
+
+**Interfaces:**
+- Consumes: Existing DINGTALK/WECOM integration modules (check `apps/server/src/` for existing API clients)
+- Produces: Real sync with record counts logged to SyncLog
+
+- [ ] **Step 1: Check existing integration modules**
+
+Run a quick scan to find existing DingTalk/WeCom API clients:
+
+```bash
+grep -r "class.*DingTalk\|class.*WeCom\|dingtalk\|wecom" apps/server/src --include="*.ts" -l
+```
+
+- [ ] **Step 2: Implement performDingTalkSync**
+
+If a DingTalk service exists, inject and use it:
+
+```typescript
+// apps/server/src/sync/sync.service.ts
+// If DingTalkService exists:
+constructor(
+  // ... existing repos
+  private readonly dingTalkService?: DingTalkService,  // optional injection
+) {}
+
+private async performDingTalkSync(lastSyncAt: Date | null): Promise<number> {
+  // Check if DingTalk integration is configured
+  const config = process.env.DINGTALK_APP_KEY;
+  if (!config) {
+    this.logger.warn('DingTalk not configured, skipping sync');
+    return 0;
+  }
+  
+  try {
+    // Pull departments
+    const depts = await this.dingTalkService?.fetchDepartments() ?? [];
+    // Pull users
+    const users = await this.dingTalkService?.fetchUsers() ?? [];
+    // If incremental, filter by lastSyncAt
+    
+    this.logger.log(`DingTalk sync: ${depts.length} departments, ${users.length} users`);
+    return depts.length + users.length;
+  } catch (err: any) {
+    this.logger.error(`DingTalk sync failed: ${err.message}`);
+    throw err;
+  }
+}
+```
+
+If no DingTalk service exists yet, keep stubs but make them log meaningful warnings:
+
+```typescript
+private async performDingTalkSync(_lastSyncAt: Date | null): Promise<number> {
+  this.logger.warn(
+    'DingTalk integration not yet implemented — add DingTalkService to SyncModule to enable real sync',
+  );
+  return 0;
+}
+```
+
+- [ ] **Step 3: Same for performWeComSync**
+
+```typescript
+private async performWeComSync(_lastSyncAt: Date | null): Promise<number> {
+  const config = process.env.WECOM_CORP_ID;
+  if (!config) {
+    this.logger.warn('WeCom not configured, skipping sync');
+    return 0;
+  }
+  // TODO: integrate with existing WeCom service
+  this.logger.warn('WeCom sync not yet fully implemented');
+  return 0;
+}
+```
+
+- [ ] **Step 4: Add sync status to SyncController**
+
+```typescript
+// apps/server/src/sync/sync.controller.ts — add endpoint
+@Get('status')
+@RequirePermission('log:view')
+async getStatus() {
+  const lastDingTalk = await this.syncService.getLastSync('dingtalk');
+  const lastWeCom = await this.syncService.getLastSync('wecom');
+  return { 
+    dingTalk: lastDingTalk ? { lastSyncAt: lastDingTalk.endedAt, status: lastDingTalk.status } : null,
+    weCom: lastWeCom ? { lastSyncAt: lastWeCom.endedAt, status: lastWeCom.status } : null,
+  };
+}
+```
+
+Add `getLastSync` to SyncService:
+
+```typescript
+async getLastSync(platform: SyncPlatform) {
+  return this.syncLogRepo.findOne({
+    where: { platform },
+    order: { createdAt: 'DESC' },
+  });
+}
+```
+
+- [ ] **Step 5: Verify**
+
+Run `npx jest --testPathPattern="sync" 2>/dev/null` if tests exist. Start server, verify the `/sync/status` endpoint returns data.
