# SimplexTasks-12 Benchmark Card

SimplexTasks-12 is the processed task collection behind the SimplexUQ benchmark. It is designed to support evaluation claims about coverage allocation for simplex-valued uncertainty quantification under fixed predictors and fixed nonconformity scores.

## Supported Claims

- Whether a fixed simplex-valued predictor exhibits allocation failure beyond its marginal coverage.
- Which heterogeneity regime best describes the observed failure pattern.
- Which conformal wrapper family is most competitive under the chosen task and stratification protocol.

## Claims The Benchmark Does Not Support

- Universal wrapper rankings across all simplex tasks.
- Deployment-readiness claims for any predictor.
- Raw-data redistribution rights beyond the terms documented in `LICENSE_NOTES.md`.

## Benchmark Contents

- 6 synthetic regimes with canonical `task.npz` bundles and copied YAML configs.
- 6 fixed-predictor real tasks with cached `(Y, U)` arrays or derived features.
- Per-task `task_card.md` files and `metadata.json` provenance records.
- Release-level rebuild instructions for the paper tables and figures.

## Reproducibility Contract

- Benchmark evaluation always operates on frozen predictor outputs.
- Default stratification rules are fixed before wrapper comparison.
- Restricted raw assets are replaced by derived arrays plus rebuild notes.
- The paper figures and tables can be regenerated from cached outputs with the commands in the release `README.md`.

## Responsible Use

Some tasks rely on non-redistributable source assets or derived features from sensitive domains such as face images. The release therefore packages evaluation-ready derived arrays rather than raw mirrors, and downstream users should preserve the source citations and usage notes attached to each task card.
