"""meta_watchdog.py — L4 自检系统的自检（看门狗的看门狗）

检查 L1-L3 各自检组件本身是否在正常运转：
- L1 functional_health_check: functional_health.json 是否 <20min（交易时段）
- L2 system_hygiene_audit: hygiene_report.json 是否 <26h（每日）
- L3 self_repair: repair_state.json 存在性 + cron 是否注册
- mofin_health 采集: mofin_health.json 是否 <20min（交易时段）
- XMPP 桥: :5805 是否可发（self_repair 的报备通道）

（2026-08-13 删除 L0 agents_health_check 检查项：MoFin 无该组件，且 L1 functional_health_check 已覆盖健康检查功能，检查项是死代码）

任何一层死了 → 推 XMPP 点名（这是最后的兜底，必须直达用户）。
频率：每小时（cron）。输出 gateway/logs/meta_watchdog.json。
