+# 集合地/解散地迁移到每日行程
+
+- **日期**: 2026-04-16
+- **服务**: hl-product-service-v2
+- **PR**: #617
+- **类型**: refactor (破坏性变更)
+
+## ⚠️ 破坏性变更
+
+`gatherPlace` 和 `dismissalPlace` 从**产品级**迁移到**每日行程天级**。
+
+### 之前（已废弃）
+
+```
+PUT /admin/product/item/{id}/itinerary
+{
+  "gatherPlace": "海拉尔",     ← 产品级，已删除
+  "dismissalPlace": "海拉尔",  ← 产品级，已删除
+  "days": [...]
+}
+```
+
+### 现在
+
+```
+PUT /admin/product/item/{id}/itinerary
+{
+  "days": [{
+    "dayNumber": 1,
+    "gatherPlace": "海拉尔",     ← 每天独立
+    "dismissalPlace": "额尔古纳", ← 每天独立
+    "dayTitle": "D1",
+    "nodes": [...]
+  }, {
+    "dayNumber": 2,
+    "gatherPlace": "额尔古纳",
+    "dismissalPlace": "满洲里",
+    ...
+  }]
+}
+```
+
+### 管理端详情响应
+
+`GET /admin/product/item/{id}` 的 `itinerary[]` 中每天包含：
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| `gatherPlace` | String | 当日集合地 |
+| `dismissalPlace` | String | 当日解散地 |
+| `dailyMileage` | BigDecimal | 当日里程(km)，自动计算 |
+| `dailyDuration` | Integer | 当日驾车时长(分钟)，自动计算 |
+
+### 小程序端详情响应
+
+`GET /mp/product/{id}` 的 `itinerary[]` 中每天同样包含 `gatherPlace`/`dismissalPlace`/`dailyMileage`/`dailyDuration`。
+
+**产品级不再有这两个字段。**
+
+### Step3路线与备品
+
+`PUT /admin/product/item/{id}/route` 也不再有 `gatherPlace`/`dismissalPlace`。
+
+### 途经路线自动生成
+
+每天的途经路线格式：`当天集合地 → 景区/活动节点 → 当天解散地`
