## Limitations

The public manifest includes train.json and a train_imgs directory. The card has no dataset-license declaration, and the model’s MIT metadata is not inherited. The official repository identifies this as v1 training data drawn from AndroidControl and ScreenSpot; later enlarged training mixtures are distinct.
