0.4.27: The Agent can make music for a project, an update started during a generation waits for it to finish, and a preview can keep the guide clip's sound.

• Agent: a new music tool makes a soundtrack for a project and places it on an audio track. The music model is downloaded on first use (about 20 GB); cards with little video memory use a built-in 8-bit form. If two attempts fail, the Agent synthesizes the music itself.
• Updates: when "Update now" is pressed while a video is generating, the page shows a waiting screen instead of a failure card, and the update starts when the job ends. The wait also covers a job on a server that another program started.
• Audio: a kept original audio track is written as lossless audio that browsers can play. A preview made with a guide clip keeps the clip's sound when that was requested.
• Long videos: when seams cannot be joined, the notes name the seams that failed first, with the step and the format. The how-to for a long video points to "Extend" below the finished video.
• Phone access: the password page is shown in Chinese when the browser's preferred language is Chinese.
• Speed: the encoded text of a prompt is kept per encoder file and prompt, so a repeated prompt starts sooner.
• Precompile: the status keeps the order of its writes, stopping responds quickly, and the diagnostic report includes the status.
• Decoding and reports: a CUDA error while decoding after sampling has finished no longer fails the video; the saved result is decoded once more in a fresh process. A process that keeps running after a CUDA error is ended, so the failure is reported instead of waiting. Diagnostic reports record the polling of Agent generations.
• Errors: a refused offline package says why, and a slow ComfyUI page is no longer blamed on the browser.
• Install: on Windows the portable Git is used when the installed Git cannot load libcurl, and the Windows certificate store is used for HTTPS checks, skipping a certificate that cannot be read. A rejected token or address stays explained under its field until it is accepted.
• Linux: on Arch, the setup names the pacman command for missing basic tools.
• Mac: after two Metal command buffer failures during sampling, a third attempt runs with Torch attention.
