+# 配房差价不再立即计入总售价 + 新增待确认差价字段
+
+## 变更说明
+
+### 1. 配房升级差价不再立即修改总售价
+之前配房时如果有房型升级差价，会立即加到订单 `totalPrice` 中。现在改为：
+- 差价记录创建为 `PENDING_CONFIRM` 状态
+- **不修改 totalPrice**
+- 等定制师确认后再正式计入
+
+### 2. 订单详情新增 `pendingUpgradeAmount` 字段
+订单详情接口返回新增字段，用于前端展示待确认的差价总额。
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| `pendingUpgradeAmount` | BigDecimal | 待确认差价总额（null=无待确认差价） |
+
+### 前端展示建议
+在金额明细区域，如果 `pendingUpgradeAmount` 不为 null 且不为 0：
+```
+总售价：¥5700.00
+待确认差价：+¥100.00（未确认）   ← 新增，用橙色/黄色标识
+已付：¥0.01
+尾款：¥5699.99
+```
+
+### 3. 配房超时问题已修复
+之前配房时确认差价弹窗提交后会卡住超时（MySQL锁冲突），已修复。
