"""人工验证用:按「金币/现金/邀请」排列组合 + 活跃/新用户对照,造一批账号。

用法(仓库根目录,venv 解释器):
    .venv/Scripts/python.exe scripts/seed_inactivity_cases.py          # 造号(会先清掉上次 vcase*)
    .venv/Scripts/python.exe scripts/seed_inactivity_cases.py --clean  # 只清理,不造

配合默认配置 INACTIVITY_RESET_DAYS=15 / INACTIVITY_WARN_DAYS_BEFORE=7,2 验证。
造完把 worker 打开(见 README/对话里的 .env),启动服务即会在 RUN_HOUR 后跑一轮。

⚠️ worker 清零针对**库里所有**符合条件的用户,不止 vcase*——dev 库里若有其它"老且有余额、
无近期活跃事件"的用户,也会被一起清。要干净验证建议用一个空/副本 dev 库。
