- device 表 + 心跳/注册/liveness 查询/ack 端点 + heartbeat_monitor_worker (扫描超时设备置 kill_alert_pending, 客户端进 App 拉取弹自启动引导) - 本期只做 pull 后置检测, 不接推送(不含 jpush) - 迁移: device_table → device_kill_alert_pending(接 main head ceb286289426, 线性单 head) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

后置检测 pull 版(spec/accessibility-liveness-pull-prompt.md):worker 检出心跳掉线即置此标记,

客户端下次进 App 拉取到 → 弹「开启自启动」引导,交互后 ack 清回。与 liveness_state 解耦,故单列。
