"""Ai-DOP 第三方对接模拟器 · 本地控制服务（任务书 P1-B / P1-G）。

- 只绑定 127.0.0.1，页面与 API 仅本机可用；
- Secret/密码/Token 只从环境变量读取，任何 API 不回显；
- 所有对外目标 host 走白名单硬阻断（默认拒绝）；
- 运行记录（RunStore）写入前统一脱敏；
- 内嵌管理 Mock API（providers.mock_api），默认端口 8018，可启停/切鉴权/注入错误；
- 三层报告：代码层 SUPPORTED/UNSUPPORTED、配置层 READY/NOT_*、数据层 NOT_RUN/ACCEPTED/TRANSFORM_PENDING/RUN_FAILED。

启动：python tools/integration-simulator/app.py   （详见 README.md）
