# Provenance and licensing notes

This document supports maintainers choosing between a **public** and **gated** Hugging Face dataset release.

## What this repository contains

- **Derived artifacts only:** SuperFit primitive assemblies, fit configs, and evaluation summaries, stored under `dataset/toys4k/` and `dataset/partobjaverse/`.
- **No Toys4K `.obj` / blend meshes** and **no PartObjaverse `.glb` meshes** are included.
- Instance IDs align with the public benchmarks so users can join against meshes they obtain separately.

## Source datasets

### Toys4K

- **Paper:** Stojanov, Thai, Rehg — CVPR 2021 ([project page](https://rehg-lab.github.io/publication-pages/lowshot-shapebias/)).
- **Access:** Registration / request form ([Google Form](https://forms.gle/w7Zf82umwaKxr9L7A)).
- **Implication for Hub:** Because Toys4K requires explicit approval, a **gated** Hugging Face dataset that asks users to acknowledge Toys4K terms is prudent even though this repo does not ship Toys4K files.

### PartObjaverse / Objaverse

- **Objaverse** metadata and objects use mixed licenses (ODC-By for the corpus; per-asset CC variants including **CC-BY-NC**).
- **PartObjaverse-Tiny** (200-object eval set used here) is a curated subset with part annotations; confirm IEEE DataPort / paper terms before open redistribution.
- **Implication for Hub:** Derived fits keyed by Objaverse UIDs should inherit **per-object license constraints**. Users must verify NC or SA restrictions before commercial use.

## Recommended release posture

| Posture | When to use |
|---------|-------------|
| **Gated** (recommended default) | Toys4K access not verified for all downloaders; mixed Objaverse per-object licenses; non-commercial CC BY-NC 4.0 restriction must be acknowledged |
| **Public** | After legal review confirms derived-assembly redistribution under CC BY-NC 4.0 is allowed and README clearly states source-dataset obligations |

## This release's license

The assemblies and documentation in this repository are released under
**Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)**
([LICENSE](LICENSE)). The Dataset may be used for **academic research,
teaching, and other non-commercial scholarly purposes only**. Commercial use
requires prior written permission from the authors.

This license applies to our **derived artifacts** (fits, configs, manifests,
documentation) and not to any third-party source meshes. Downstream use must
still independently comply with Toys4K and Objaverse / PartObjaverse terms
for the original 3D assets.

## Maintainer checklist before `git push`

1. Run `python scripts/sanitize_configs.py` (null `AOT_ARTIFACT_FILE`).
2. Run `python scripts/build_manifest.py`.
3. Run `python scripts/validate_release.py`.
4. Confirm `git lfs track "*.pkl"` / `.gitattributes` before committing binaries.
5. Set Hugging Face dataset visibility (gated vs public) and acceptance text referencing this file.
