Rights and attribution notice

This repository publishes AIFlow research checkpoints and reports, not the original handwriting databases.

HWRT database material used during research is treated as ODbL-1.0. Database attribution and share-alike implications must be reviewed for any derivative database distribution.
CROHME-derived grouping and behavior heads are restricted to non-commercial research use in this release.
UJI Pen and Pendigits source terms remain applicable to their respective source material.
No permission is granted here to redistribute the original datasets.
The checkpoints have not passed AIFlow commercial distribution, on-device release, or product-validation gates.

The repository is therefore marked license: other and the included weights must not be used commercially. A commercial AIFlow checkpoint must be trained from a separately approved P-track federation.
