實測 df71c9a 部署後 coverage_evaluator 生效:
  - monitoring: 2 hosts match Prometheus targets
  - alerting: 74 筆 (22 green + 52 red)
  - km: 0 (錯誤: column "ke.body" does not exist)

真因: knowledge_entries 表欄位是 'content' 不是 'body'
修復: ke.content ILIKE '%name%' OR ke.title ILIKE '%name%'

同時清 unused import (typing.Any)

下輪 coverage_evaluator tick 將正確 UPDATE auto_km_creation 維度
解鎖完整 3 維 coverage (monitoring/alerting/km)
