 /**
- * Surge 脚本：gamertag 捕获 + FIFO 配对写入 cartId_history
- *   - peoplehub 响应到达时捕获 gamertag
- *   - 若 pending_carts 有等候的 cart → 取最老一条配对
- *   - 否则把 gamertag 快照 push 进 pending_gamertags 等待
+ * Surge 脚本：仅捕获 peoplehub 响应中的 gamertag，存入 $persistentStore
+ *
+ * 两个用途：
+ *   1. gamertag 这个 key：始终保持最新 gamertag（供其他脚本和 carthistory 页面使用）
+ *   2. gamertag_snapshot 这个 key：{gamertag, ts} 格式，供 authorization&cartId.js
+ *      在 cart 请求到达时用作历史记录的"当前 gamertag"依据
+ *
+ * 本脚本不再写入 cartId_history，也不再维护任何队列。
  *
  * Surge 配置：
  * [Script]
