實證 rule_stats 跑完後發現 2 條 100% noise_rate 規則:
- PostgreSQLDiskGrowthRate (tp=0 fp=2)
- NoAlertsReceived2Hours (tp=0 fp=1)
加上 MoWoooWorkDown (33%), KubePodCrashLooping (25%)
新增 hermes_rule_quality_job.py (~210 行):
每日 04:00 Taipei 分析 alert_rule_catalog:
- threshold: noise_rate >= 0.7 AND 樣本 >= 5
- 為每條寫 aol('rule_rejected', proposed_action='review_or_deprecate')
- 推 Telegram 摘要給 SRE group
統帥鐵律對齊:
✅ 不自動改 review_status (人工決策 deprecate,AI 只推建議)
✅ threshold 作為「觸發討論」而非「最終決策」
✅ aol(rule_rejected) 留 trail,未來可升級 LLM 辯證
解鎖 E3 Hermes 基礎: 後續可加 LLM 分析假報真因 (expr 缺 for: window、
label match 太寬泛、metric 本身 noisy 等),產出具體改進建議.
