+BAPPS native 2AFC human preferences; ordered reference, p0, p1 images.
+
+Two training votes and five validation votes per triplet. Ties are excluded
+from the hard-choice view; fractions and vote counts remain in metadata.
+Only 2AFC is included, not JND. No perceptual model generates labels. Original
+code is BSD-2-Clause; it does not establish a license for the image dataset.
+
+Repackaged as parquet for [tasksource](https://github.com/sileod/tasksource) by [scripts/repackage_dataset/](https://github.com/sileod/tasksource/tree/main/scripts/repackage_dataset).
+
+## Release scope
+
+Bounded samples of the eligible native annotations; full classification ontologies are retained.
+
+- default: train: 1,000, validation: 100.
