/**
 * R6 H4-3 现场演示：失败 → watchdog 有界自动重试 → 纠偏/成功（真实 LLM 编排）。
 * 通过 GW_TEAM_FAIL_ONCE=first-cli 让第一个外部 CLI 子任务的第 1 次尝试确定性失败，
 * 引擎 watchdog 记录 auto-retry（injected:true）并退避重试，后续尝试成功。
 * 结束校验：①watchdog.json 含 injected 自动重试 ②该子任务 attempts≥2（先 dead 后 done）
 * ③整体无 dead 子任务（评审若打回则走 correction 纠偏，同样计入证据）。EXIT=0 闭环。
