+"""15 天不活跃清零相关表。
+
+- inactivity_reset_log:每次清零一行,记清零前三桶余额 + 原因 + 判定时活跃时间/不活跃天数,
+  供纠纷排查(需求①)。清零同时另写 3 条钱包流水(biz_type=inactivity_reset),资金流可逐笔回溯。
+- inactivity_notification_log:每次预警一行,记推送时余额快照 + 档位 + 通道 + 状态,
+  兼作"预警去重"依据(created_at > last_active)与"待推送"占位 outbox(v1 通道=log)。
+
+append-only,不更新。user_id 只索引、不设外键(同 analytics_event,避免删用户级联/历史留痕)。
