This release preserves selected simulation checkpoint tensors, normalization
values and demonstration membership. Path-bearing metadata has been sanitized
and relocated; export-receipts.json records original/export checksums.

Paper, website media, logos and third-party packages are outside this artifact
license. The models use a torchvision ResNet18 architecture; the released source
constructs it with weights=None. No separate pretrained DINO weights are included.
Simulator software and robot/scene assets are installed separately, not bundled
as standalone software/assets here. Hardware v1 artifacts are documented separately under hardware/v1/.
