"""store_mapping 加京东 deeplink 失效标记列 jd_deeplink_invalid_at

Revision ID: store_mapping_jd_dl_invalid

Revises: store_mapping_tb_dl_invalid

|
京东同淘宝: 缓存的店内搜索 deeplink 会失效(打开是"当前门店超出配送范围"页)。pricebot 比价撞到
|
|
失效页时回退正常搜店, 并 server→server 通知把该 storeId 的 deeplink 标记失效。本列记失效时刻
|
|
(NULL=有效); lookup 反查时过滤掉已失效的京东候选, 不再返回坏 deeplink。
|
|
与淘宝 taobao_deeplink_invalid_at 对称; 用时间戳而非布尔: 留痕可审计、可统计失效率, 不销毁原 deeplink。
