 时间字段为 Unix 秒。`currentCycle` 是按当前仍有效的最长限额窗口计算的当前重置周期；`totalTokens` 由 `account/usage/read` 的每日 Token bucket 汇总，受每日粒度影响，无法精确切分周期起止日期内的单日数据。`summary.peakDailyTokens` 是同一当前重置周期内每日 Token bucket 的最大值，不再直接采用 app-server 未限定口径的峰值摘要；没有有效窗口或周期内没有每日数据时为 `null`。app-server 未提供的其他摘要字段可以是 `null`；列表应返回数组而非 `null`。
+`resetCredits` 仅在 app-server 返回可用重置卡且 `availableCount > 0` 时出现；`expiresAt` 是已返回卡片的去重到期时间列表，服务端未提供卡片详情时可以为空。匿名公开 Dashboard 不返回该字段。
