Preserve all 490 public IDs and media paths. Refresh GPT, Muse Spark, and Alibaba Qwen responses and uniformly rescore. One Qwen numeric-MIDI input exceeds the provider limit and retains its historical response, documented in provenance.
Publish the reference and optional task-dependent scorers, CLI, regression tests, and instructions for using the existing public question CSV. No answer keys, predictions, or musical inputs are uploaded.
