"""预算偏差告警归因回填 —— yanxue-20260914-budget-p13p14-activation（P1-③ 激活）
|
||
|
||
两类动作:
|
||
1) attribution 为空的历史 open 告警 → 走现成接口 GET /budget/deviation-alerts/{id}/attribution
|
||
（端点在响应前现场组装归因并落库，见 app/api/budget.py:1004-1012）
|
||
2) 已有旧口径归因的告警 → 用修正后的科目口径重算覆盖（旧值见 /root/WB_WS/_backups/p13p14-20260914/）
|
||
另: scenario_id 为空且 alert_type 命中 scenario_suggestions → 补 scenario_id（让告警"能解释、能关"）
|
||
|
||
用法:
|
||
/usr/bin/python3 scripts/kpi_alert_attribution_backfill.py # dry-run
|
||
/usr/bin/python3 scripts/kpi_alert_attribution_backfill.py --apply
