"""
通过「知你客服12号」Agent 实测：在 user_data 下创建 bbb.md（对应 D:\\aaa\\aiagent\\user_data\\bbb.md）。

依赖：API(默认 8037)、Redis、Celery、LLM；引擎需已修复 End 节点优先于 vector-upsert（否则界面 result 可能仍不对，但 file_write 可能已执行）。

用法:
  cd backend
  .\\venv\\Scripts\\python.exe scripts\\e2e_zhini12_bbb_md.py

环境变量:
  API_BASE            默认 http://127.0.0.1:8037
  E2E_AGENT_NAME      默认 知你客服12号
  E2E_REL_FILE        默认 user_data/bbb.md
  E2E_FILE_CONTENT    写入内容，默认带标记行便于校验
  E2E_RESTART_CELERY  默认 1；设为 0 跳过重启 Worker
  E2E_USE_ABSPATH_MSG 设为 1 时在用户话术中额外要求使用绝对路径 D:\\aaa\\aiagent\\user_data\\bbb.md
