# Ready-to-upload SimplexTasks-12 Croissant metadata Validated on 2026-10-16 against the public, de-anonymised Hugging Face release. Upload `SimplexTasks-12_Croissant_VALIDATED.zip` to the OpenReview Croissant File field. It contains 12 individual JSON files, one per task. Dataset URL: https://huggingface.co/datasets/liangyou03/SimplexTasks-12-data All 12 files pass all four official online checks: JSON format, Croissant schema, required Responsible AI metadata, and record generation. Reports are saved in validator_reports/. The official record-generation test checks that a record can be generated; it is not a scientific or legal certification. The public dataset now includes 12 lossless Parquet tables. Every downloaded table was checked without authentication against the original frozen NumPy arrays for exact value, dtype and row-order equality. Sources remain unchanged. The metadata points to an immutable data commit, preventing later repository edits from silently changing validation inputs. The dataset card license category is now `other`, matching CITATION.cff and the existing task-specific artifact license notice. Metadata links this notice and retains upstream source restrictions; no new blanket license or third-party rights are granted. The metadata and validation reports are also published in the Hugging Face repository. The previous NumPy-based ZIP is superseded by this package.
