# 项目售后归档模块设计方案

## 概述

基于ProjectPayment、ProjectFeedback、Product等表结构和现有的stage-aftercare组件，设计完整的项目售后归档模块，包含**验收尾款**、**客户评价**、**项目复盘**三大核心功能，通过数据分析实现项目执行效率和团队绩效的科学评估。

## 数据表结构分析

### 1. ProjectPayment（项目付款表）

现有结构已支持尾款管理：
- **type**: "final" - 尾款类型
- **stage**: "aftercare" - 售后归档阶段
- **status**: "pending" | "partial" | "completed" - 支付状态
- **voucherFile**: 指向ProjectFile的付款凭证
- **product**: 支持按Product分摊尾款

### 2. ProjectFeedback（客户反馈表）

现有结构支持多维度评价：
- **project**: 关联项目
- **product**: 关联具体空间产品
- **rating**: 1-5分评分
- **feedbackType**: "suggestion" | "complaint" | "praise"
- **content**: 评价内容
- **stage**: 评价阶段

### 3. Product（空间设计产品表）

现有结构支持复盘分析：
- **profile**: 负责设计师
- **stage**: 当前阶段状态
- **status**: 产品状态
- **estimatedDuration**: 预估工期
- **order**: 排序顺序
- **reviews**: 产品评价数组

## 三大功能模块设计

### 1. 验收尾款模块

#### 1.1 功能结构

```typescript
interface FinalPaymentModule {
  // 尾款总览
  paymentOverview: {
    totalAmount: number;          // 尾款总额
    paidAmount: number;           // 已支付金额
    remainingAmount: number;       // 待支付金额
    dueDate: Date;              // 应付款日期
    overdueDays: number;          // 逾期天数
    status: PaymentStatus;       // 支付状态
  };

  // 按产品分摊
  productBreakdown: Array<{
    productId: string;
    productName: string;
    productType: string;
    amount: number;
    percentage: number;
    paidAmount: number;
    vouchers: PaymentVoucher[];
  }>;

  // 支付凭证管理
  paymentVouchers: Array<{
    id: string;
    amount: number;
    paymentMethod: string;
    paymentTime: Date;
    voucherFile: Parse.Object;
    verifiedStatus: 'pending' | 'verified' | 'rejected';
    ocrResult?: OCRResult;
    notes?: string;
  }>;
}

enum PaymentStatus {
  PENDING = 'pending',       // 待支付
  OVERDUE = 'overdue',       // 逾期
  PARTIAL = 'partial',       // 部分支付
  PAID = 'paid',           // 已支付
  DISPUTED = 'disputed'     // 争议中
}
```

#### 1.2 OCR智能识别

**支付凭证OCR识别结构**：
```typescript
interface OCRResult {
  confidence: number;           // 识别置信度
  amount: number;              // 识别金额
  paymentMethod: string;       // 支付方式
  transactionId?: string;     // 交易号
  payerName?: string;         // 付款人姓名
  paymentTime?: Date;         // 付款时间
  merchantName?: string;      // 收款商户
  rawText: string;           // 原始识别文本
  warnings?: string[];        // 识别警告
}
```

#### 1.3 业务流程

```mermaid
graph TD
    A[进入售后归档] --> B[加载尾款信息]
    B --> C{是否已有尾款记录?}
    C -->|否| D[从报价自动生成尾款]
    C -->|是| E[显示现有尾款状态]
    D --> F[按产品分摊尾款]
    E --> G[尾款管理界面]
    F --> G
    G --> H{支付状态}
    H -->|待支付| I[上传支付凭证]
    H -->|已支付| J[显示凭证列表]
    I --> K[OCR自动识别]
    K --> L[人工确认信息]
    L --> M[更新支付状态]
    M --> N[尾款结清]
    J --> N
    N --> O[进入评价阶段]
```

### 2. 客户评价模块

#### 2.1 多维度评价体系

```typescript
interface CustomerEvaluation {
  // 基础信息
  evaluationId: string;
  projectId: string;
  customerId: string;
  evaluationTime: Date;

  // 整体评价
  overallRating: {
    score: number;              // 综合评分 1-5
    comments: string;          // 整体评价
    wouldRecommend: boolean;    // 是否愿意推荐
    improvementSuggestions: string[];
  };

  // 分维度评价
  dimensionRatings: Array<{
    dimension: 'design_quality' | 'service_attitude' | 'delivery_timeliness' | 'value_for_money';
    score: number;            // 维度评分
    weight: number;            // 权重
    comments?: string;        // 维度评价
  }>;

  // 产品级评价
  productRatings: Array<{
    productId: string;
    productName: string;
    spaceSatisfaction: number;  // 空间满意度
    designRating: number;       // 设计评分
    functionalityRating: number; // 功能性评分
    issues: string[];          // 存在问题
    improvements: string[];      // 改进建议
    photos?: string[];         // 实际效果照片
  }>;

  // 评价验证
  verification: {
    isVerified: boolean;
    verificationMethod: 'customer_confirmation' | 'project_completion' | 'payment_confirmation';
    verificationTime: Date;
    verifiedBy: string;
  };
}
```

#### 2.2 智能评价引导

**评价引导策略**：
- **实时反馈**: 客户可在项目过程中随时记录反馈
- **分阶段提醒**: 在关键节点(设计确认、交付完成)提醒评价
- **个性化问题**: 基于项目类型生成针对性评价问题
- **可视化对比**: 对比预期效果与实际效果的差异

#### 2.3 评价数据结构

```typescript
// 扩展ProjectFeedback表结构
interface EnhancedProjectFeedback extends ProjectFeedback {
  // 产品关联
  product?: Parse.Object;

  // 多维度评分
  dimensionScores?: {
    designQuality: number;     // 设计质量
    serviceAttitude: number;   // 服务态度
    deliveryTimeliness: number; // 交付及时性
    valueForMoney: number;    // 性价比
  };

  // 评价上下文
  context?: {
    evaluationStage: string;    // 评价阶段
    touchpoints: string[];     // 接触点
    emotions: string[];        // 情感标签
    expectations: string[];    // 期望值
  };

  // 改进建议分类
  improvementCategories?: {
    design: string[];          // 设计改进
    service: string[];         // 服务改进
    process: string[];        // 流程改进
    communication: string[];    // 沟通改进
  };

  // 推荐意愿
  recommendationWillingness?: {
    score: number;            // 推荐评分 1-10
    reasons: string[];         // 推荐原因
    barriers?: string[];       // 推荐障碍
    networkScope: string[];   // 愿意推荐的圈层
  };
}
```

### 3. 项目复盘模块
