+🔴 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
