推送暂缓改 pull:worker 检出掉线即置 kill_alert_pending(与 liveness_state 解耦,心跳恢复 touch_heartbeat 不清,规避竞态),客户端进 App 拉 GET /device/liveness 命中→弹自启动引导,POST /device/liveness/ack 清。含 alembic 加列(临时 sqlite 验通)。spec: accessibility-liveness-pull-prompt.md Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
