"""system_audit.py — MoFin 全局系统审计
|
||
|
||
每日收盘后运行，遍历所有对象生命周期，发现缺口→自动修复/记录。
|
||
|
||
审计维度：
|
||
1. 信号管道 — 今日signal_news产出vs处理量，有积压则预警
|
||
2. 股票生命周期 — 关注列表是否有条件触发的、自选是否有策略缺失的
|
||
3. 策略状态 — 过期/偏离/无止损等异常策略
|
||
4. 建议闭环 — pending超过7天的未执行建议
|
||
5. 组合健康 — 弱势占比、仓位集中度、现金水位
|
||
6. 数据管道 — 今日采集是否正常、有无cron报错
|
||
7. 系统服务 — Dashboard/XMPP/小果API在线状态
|
||
|
||
输出：JSON + 摘要文本，推送给老爸。
