+
+## Data Models
+
+### Request/Response Models
+
+```csharp

+public class WechatPayRequest
+{
+    public string OrderNo { get; set; }
+    public decimal Amount { get; set; }
+    public string Body { get; set; }
+    public string Attach { get; set; }

+}
+
+public class WechatPayData
+{
+    [JsonPropertyName("appId")]

+    
+    [JsonPropertyName("timeStamp")]
+    public string TimeStamp { get; set; }
+

+```
+
+### Database Entities
+
+```csharp

+    public DateTime UpdateTime { get; set; }
+}
+```
+
+## Correctness Properties
+
+*A property is a characteristic or behavior that should hold true across all valid executions of a system-essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.*
+
+### Property 1: 支付签名正确性
+
+*For any* set of payment parameters and secret key, generating a signature and then verifying it with the same parameters should return true.
+
+**Validates: Requirements 1.4, 7.1, 7.2**
+
+### Property 2: 支付回调幂等性
+
+*For any* payment notification, processing it multiple times should produce the same result as processing it once (order status should not change after first successful processing).
+
+**Validates: Requirements 2.8**
+
+### Property 3: 资产扣减原子性
+
+*For any* mixed payment transaction, either all asset deductions succeed or none of them succeed (transaction rollback on failure).
+
+**Validates: Requirements 6.7**
+
+### Property 4: 余额扣减正确性
+
+*For any* balance payment, the user's balance after payment should equal the original balance minus the payment amount.
+
+**Validates: Requirements 3.3, 3.4**
+
+### Property 5: 支付记录完整性
+
+*For any* successful payment, there should be a corresponding record in the profit_pay table with correct order number, amount, and payment type.
+
+**Validates: Requirements 8.1, 8.2**
+
+## Error Handling
+
+### Payment Errors
+
+| Error Code | Description | Handling |
+|------------|-------------|----------|
+| NOTENOUGH | 余额不足 | 返回错误提示，不扣款 |
+| SIGNERROR | 签名错误 | 拒绝请求，记录日志 |
+| ORDERPAID | 订单已支付 | 返回成功，不重复处理 |
+| SYSTEMERROR | 系统错误 | 重试或返回错误 |
+
+### Transaction Handling
+
+```csharp
+public async Task<bool> ProcessPaymentAsync(PaymentRequest request)
+{
+    using var transaction = await _context.Database.BeginTransactionAsync();
+    try
+    {
+        // 1. 验证订单状态
+        // 2. 扣减用户资产
+        // 3. 更新订单状态
+        // 4. 记录支付流水
+        // 5. 触发后续业务（抽奖等）
+        
+        await transaction.CommitAsync();
+        return true;
+    }
+    catch (Exception ex)
+    {
+        await transaction.RollbackAsync();
+        _logger.LogError(ex, "Payment processing failed");
+        throw;
+    }
+}
+```

+## Notes
+
+- Tasks marked with `*` are optional and can be skipped for faster MVP
+- Each task references specific requirements for traceability
+- Checkpoints ensure incremental validation
+- Property tests validate universal correctness properties
+- Unit tests validate specific examples and edge cases
+- 每迁移完成一个接口，都需要在docs/API接口文档.md中标记迁移状态和新接口地址
+- 迁移前必须先查看PHP代码了解详细业务逻辑，确保功能一致性
+- 支付系统涉及资金安全，需要特别注意签名验证和事务处理
+- 支付回调需要确保幂等性，防止重复处理
