+
+## 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: 商品列表过滤和排序正确性
+
+*For any* goods query with type filter, the returned list SHALL only contain goods matching the specified type (or all goods if type=-1), with status=1, unlock_amount <= user consumption, sorted by sort DESC then id DESC.
+
+**Validates: Requirements 1.1, 1.4, 1.5, 1.6**
+
+### Property 2: 商品详情数据完整性
+
+*For any* goods detail request, the response SHALL contain complete goods info, lock_info structure, join_user list, collection_is flag, and limitInfo structure with all required fields present.
+
+**Validates: Requirements 2.1, 2.4, 2.5, 2.6, 2.7**
+
+### Property 3: 奖品概率计算正确性
+
+*For any* prize item in goods detail, the probability (pro) SHALL be calculated as (surplus_stock / total_surplus_stock * 100) and formatted correctly.
+
+**Validates: Requirements 2.3, 3.2**
+
+### Property 4: 子奖品数据完整性
+
+*For any* child prize request, the response SHALL contain all child items with real_pro calculated and shang_info included for each item.
+
+**Validates: Requirements 3.1, 3.2, 3.3**
+
+### Property 5: 箱号管理数据正确性
+
+*For any* box detail request, the response SHALL contain boxes with correct surplus_stock, support specified sort order, and include goodslist summary for each box.
+
+**Validates: Requirements 5.1, 5.2, 5.3, 5.4**
+
+### Property 6: 收藏操作往返一致性
+
+*For any* collection add operation followed by collection list query, the added goods SHALL appear in the list; for any remove operation, the goods SHALL not appear in the list.
+
+**Validates: Requirements 6.1, 6.2, 6.4**
+
+### Property 7: 中奖记录数据完整性
+
+*For any* prize logs request, the response SHALL contain paginated records with user_info, prize_info, shang_info, and addtime for each record, supporting shang_id filtering.
+
+**Validates: Requirements 8.1, 8.2, 8.3, 8.4**
+
+### Property 8: API响应格式一致性
+
+*For any* API response, the structure SHALL contain status (int), msg (string), and data (object) fields consistent with PHP API format.
+
+**Validates: Requirements 10.1, 10.3**
+
+## Error Handling
+
+### 错误码定义
+
+| 错误码 | 描述 | 场景 |
+|--------|------|------|
+| 0 | 请求失败 | 通用错误 |
+| 1 | 请求成功 | 成功响应 |
+| -1 | 未登录 | Token无效或过期 |
+| -2 | 商品不存在 | 商品ID无效 |
+| -3 | 商品已下架 | 商品状态非1 |
+| -4 | 已收藏 | 重复收藏 |
+| -5 | 未收藏 | 取消未收藏的商品 |
+
+### 异常处理策略
+
+```csharp
+public class GoodsNotFoundException : BusinessException
+{
+    public GoodsNotFoundException(int goodsId) 
+        : base(-2, $"商品不存在: {goodsId}") { }
+}
+
+public class GoodsOfflineException : BusinessException
+{
+    public GoodsOfflineException(int goodsId) 
+        : base(-3, $"商品已下架: {goodsId}") { }
+}
+
+public class AlreadyCollectedException : BusinessException
+{
+    public AlreadyCollectedException() 
+        : base(-4, "已收藏") { }
+}
+```
+
+## Testing Strategy
+
+### 单元测试
+
+- 测试商品列表过滤逻辑
+- 测试概率计算算法
+- 测试箱号排序逻辑
+- 测试收藏状态切换
+
+### 属性测试
+
+使用FsCheck或类似库进行属性测试：
+
+- **Property 1**: 商品列表过滤和排序 - 生成随机商品数据，验证过滤和排序正确性
+- **Property 3**: 概率计算 - 生成随机库存数据，验证概率计算公式
+- **Property 6**: 收藏往返 - 生成随机收藏操作，验证状态一致性
+- **Property 8**: API格式 - 验证所有响应符合标准格式
+
+### 集成测试
+
+- 测试完整的商品查询流程
+- 测试缓存命中和失效
+- 测试与数据库的交互
+
+### 测试配置
+
+```csharp
+// 属性测试配置
+[Property(MaxTest = 100)]
+public Property GoodsListFilteringProperty()
+{
+    // 生成随机商品和查询条件
+    // 验证过滤结果正确性
+}
+```

+## 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
