本仓库以 Codex 内部版本聚合平台安装包；Windows MSIX 的四段包版本会单独列在“平台包 / build”列。

## 校验

建议下载后使用随附的 `SHA256SUMS.txt` 校验文件完整性。

## Windows 安装策略提示

如果安装 `.Msix` 时提示“你的系统管理员已阻止此程序”，通常是当前设备策略不允许从商店外安装 MSIX / AppX 包，或应用安装器 / AppX 部署服务被禁用。请优先尝试 Microsoft Store 官方页面；公司、学校或其他受组织策略管理的设备需要联系设备管理员放行，本镜像不会绕过本机安装策略。

## 来源说明

本项目只镜像官方安装包，不修改、不重打包、不破解安装器。更完整的上游指纹记录在随附的 `release-manifest.json` 中。

This mirror groups platform installers by the Codex app's internal version; the four-part Windows MSIX package version is listed separately in the platform package / build column.

## Verification

We recommend verifying downloaded files with the attached `SHA256SUMS.txt`.

## Windows install policy note

If installing the `.Msix` file shows "This app has been blocked by your system administrator", the device is usually blocking sideloaded MSIX / AppX installation, or App Installer / AppX deployment has been disabled by policy. Prefer the official Microsoft Store page first. Work, school, or otherwise managed devices need an administrator to allow the install; this mirror does not bypass local install policies.

## Source notes

This project only mirrors official installer packages. It does not modify, repackage, or bypass installer authorization. The full upstream fingerprints are included in the attached `release-manifest.json`.
