| # Reconstructing the fixed benchmark |
|
|
| `manifest.csv` identifies the 100 selected source scores by content ID (CID) and |
| MuseScore score ID. `attribution.json` preserves the available source links and |
| embedded credits. Obtain source scores from the original MetaScore distribution |
| or a source authorized to provide the work, respecting its terms. |
|
|
| Complete MIDIs in this release were converted from the corresponding MSCZ files |
| before selecting the fixed windows. The window builder is |
| `preprocess/build_metascore_test.py` in the DAMN development repository. Its |
| source and the serializer dependency are archived under `reconstruction/` for |
| inspection and reproduction. They were archived from the local development |
| checkout on 2026-10-31; this is not a claim that the inference-only submission |
| repository contains the preprocessing pipeline. |
|
|
| Install `reconstruction/requirements.txt`. The archived portable `config.py` |
| replaces deployment-specific paths with relative placeholders; window parsing |
| and serialization are unchanged. From `reconstruction/`, with the original |
| directory structure restored, including all 100 source entries, use: |
|
|
| ```bash |
| python -m preprocess.build_metascore_test --source /path/to/MetaScore-SFT-100 --output /path/to/rebuilt_challenge_test |
| ``` |
|
|
| Use a fresh output directory (or the builder's explicit `--output` option) to |
| avoid replacing the released original test artifacts. The protocol is a fixed |
| four-bar prompt plus optional pickup and a twelve-bar continuation. |
|
|
| For `QmbQPgvc93q2bBKvPaVRWNJDvaxSB8kHxVKXxQD2W5W1Qx`, `rights_conflicts.json` |
| lists all expected source/derived paths and their SHA256 checksums. Use the |
| source score/MIDI to the paths in `manifest.csv` and the window manifest; |
| compare checksums and rebuild the specified window. All 100 entries, window |
| indices and selection reasons remain fixed. This release intentionally does |
| not provide a downloader that bypasses the original source's access controls. |
