"""Codex 原生 UI host 入仓清单单测（见 docs/codex-native-ui-alignment.md §4 第 4 项）。

只做静态断言，不起服务、不调网络、不读密钥：
- appserver-methods.json 是合法 JSON、179 个方法、无重复；
- app-server-bridge.mjs 里 7 个仿真方法都在（读文件文本断言方法名出现）；
- 仓内无 cloud/codex-ui-host/original/ 目录（650MB 原版栈不入仓）；
- scripts/run-codex-ui.sh 存在且可执行。

路径一律以仓库根（本文件向上两级）为基准，不写死绝对路径。
