 打卡为匿名本机 POC：`src/data/check-in/tasks.ts` 会为当前 POI 仓库中的全部已发布点位生成打卡任务；点位下线后会自动停止新打卡，重新发布后仍保留本机历史记录以防重复领奖。所有点位的游客入口坐标与安全到达范围仍需 iOS 现场复核后才能用于正式验收。每个开放点位首次成功打卡增加 10 积分，累计完成 1、2、3 个开放点位时依次解锁徽章。积分、徽章与足迹使用独立版本化存储键；v1 旧格式首次升级时只迁移当前开放点位记录，进入 v2 后则保留合法历史足迹。清除操作只删除打卡数据，不影响路线和偏好。打卡记录不保存经纬度、定位精度或轨迹。微信客户端无法可靠识别系统级缓存位置或虚拟定位，因此本期只承诺每次点击重新调用定位接口并校验微信返回的精度，不提供虚拟定位测试入口或生产级反作弊承诺。
