"""
🔴 深度验证：真正的端到端管线测试
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
这不是单元测试。这是启动真实服务、跑真实管线、验证真实输出的测试。

测试内容:
  1. 启动 FastAPI 服务
  2. 上传真实的 COBOL/COPYBOOK/Java 文件
  3. Worker 处理管线
  4. 验证输出文件存在且内容正确

前提: FastAPI + Worker 已经在运行
    Windows: start uvicorn web.api:app --port 8000 & python web/worker.py
    WSL:     python3 web/worker.py
