            预编译的 Node.js ARM64 musl 二进制文件，供 ARM64 OpenWrt/iStoreOS 设备使用。

            Node.js 官方 [unofficial-builds](https://unofficial-builds.nodejs.org/) 仅提供 x64 musl 构建，不提供 ARM64 musl。
            此 Release 使用 Alpine Linux ARM64 (musl libc) 环境打包。

            ## 版本说明

            | 文件 | 版本 | 用途 |
            |------|------|------|
            | `node-v23.x.x-linux-arm64-musl.tar.xz` | V2 (当前) | OpenClaw v2026.3.11+ (要求 >= 22.16.0) |
            | `node-v22.x.x-linux-arm64-musl.tar.xz` | V1 (旧版) | OpenClaw v2026.3.8 及更早版本 |

            ## 构建模式

            两种版本均使用 **Alpine apk 模式** 构建:
            - **V2**: 使用 Alpine `nodejs-current` 包 (v23.x)，满足 OpenClaw >= 22.16.0 的要求
            - **V1**: 使用 Alpine `nodejs` LTS 包 (v22.x)，兼容旧版 OpenClaw

            `openclaw-env setup` 会在 ARM64 musl 设备上自动从此处下载合适的版本。
