+- 每天 `Asia/Shanghai` 23:55 为计划时点，归属当天；只允许在 23:55:00（含）到 23:56:00（不含）内开始读取。每天独立保存完整逐车状态；月度展示月末当天、年度展示12月31日快照，不累加每日存量。
 - `captured_at` 是程序记录的实际开始读取时间，`scheduled_for` 是计划时点；两者不宣称完全相同。
 - 一致性读取可在窗口内开始后继续执行；持久化失败最多重试三次，始终使用同一份已取得数据，不重新读晚到的台账。
 - 当月在截止前显示实时点；年末前当年年度点显示实时点。截止后只能显示归档、归档中、失败或缺失。12 月快照直接用作年度年末点。

-保持服务在计划时点在线。停止期间错过的 eligible 月份会在重启时记为 MISSED；已 FAILED 的记录保留诊断标记。记录到启用前没有归档，不能用重启时的实时数回填。日志前缀为 `[asset-history]`，包含年月及 captured/already-complete/locked/failed/missed 结果，不记录客户明细或连接凭据。
+增量迁移把 `period_month CHAR(7)` 改为 `period_key CHAR(10)`，原唯一索引继续约束期间键和版本；新增可空 `daily_enabled_at`。这是一次性 ALTER，不能重复执行。应在目标库完成迁移后启动新版服务并设置采集开关；旧版程序不能直接使用新字段名。迁移不启动采集，也不修改旧归档的计划/实际时间。当前页面仍提供月度和年度浏览，普通日期快照保存在数据库中。
 
-建议仅让受控服务账号写快照表；源表仍只需读权限。多实例可启用同一数据库下的同一采集配置，命名锁和数据库唯一约束共同保证幂等。启用开关为进程级配置，`enabled_at` 是历史启用记录，不能仅根据该记录判断某个进程现在是否运行调度器。

 其余字段见模板。部门、负责人、主体缺失须显式留空，不能用今日台账补齐；部门/个人权限因此可能看不到未归属的运营车辆，这是数据缺失而非自动扩大授权的理由。展示型号、品牌、原始车辆状态按历史来源保存；历史状态映射复用现有分类函数，不接受退出运营车辆或未知运营状态作为有效存量。归档分类由导入校验程序计算，不直接信任文件中的分类列。
