"""风量研判的真实端到端验证：用真实模型跑一条提示词，观察技能是否被触发与遵循。

观察点（按 skill-creator 的评测要求，同时看结果与轨迹）：
1. 技能是否被触发（主 Agent 是否委派给 airflow-review-orchestrator 子 Agent）；
2. 子 Agent 是否读了 /skills/airflow-review/SKILL.md，并按索引读了 references/stages/01-*.md；
3. 是否按契约调用了 parse_airflow_measurement_report（参数名与 scope 是否正确）；
4. 返回值里的真实读数是否被如实引用（总进风 35181 / 总回风 35713）；
5. 是否把 pending_review 与依据不足原样报出，而不是编造结论。

用法（需服务已启动且模型密钥可用）：

    python main.py &                                   # 或 bash scripts/start_server.sh start
    python scripts/airflow_e2e.py                      # 默认：测风报表 + 数据准备提示词
    AIRFLOW_E2E_FILE="布尔台矿矿井风量分配计划20241201(1).pdf"     AIRFLOW_E2E_PROMPT="请对布尔台矿做完整研判……" python scripts/airflow_e2e.py

这不是回归测试（依赖真实模型与网络），是一次需要人工判读的端到端验证；
离线回归在 tests/test_airflow_*.py。
