+
+## 统一约定（全端一致）
+
+### 1）事件类型（event_type）
+- 页面曝光：`page_exposure`
+- 点击事件：`click`
+
+> iOS 侧可映射为：`KBMaiPointGenericReportTypePage / KBMaiPointGenericReportTypeClick`
+
+### 2）事件名称（event_name）
+- 统一使用 `lower_snake_case`，不绑定任何端的类名/资源名
+- 页面曝光统一前缀：`enter_`
+- 点击事件统一前缀：`click_`
+
+### 3）事件参数（value / params）
+- **所有事件都固定带**：`token`（`NSString`，有就传真实值；没有就传空字符串 `""`）
+- 建议额外固定带：`page_id`（页面/区域统一ID）
+- 点击类事件建议固定带：`element_id`（控件/入口统一ID）
+- 列表/集合类点击建议带：`index`（`NSInteger`）与业务 `id`（如 `theme_id` / `product_id`）
+
+参数示例（最小）：
+```json
+{ "token": "", "page_id": "shop", "element_id": "search_btn" }
