# Source provenance and licenses

This repository preserves separate upstream source trees with evaluation adapters. It does not replace the upstream licenses or claim ownership of their model implementations. Native pretrained checkpoints are downloaded from their authors' model repositories instead of being redistributed here.

| DecMem | https://github.com/KlingAIResearch/DecMem | `DecMem/LICENSE`, embedded component notices including ThunderKittens |
| Matrix-Game 2.0 | https://github.com/SkyworkAI/Matrix-Game | `Matrix-Game/LICENSE` and component notices |
| LIVE | https://github.com/Junchao-cs/LIVE | `LIVE/LICENSE`, `LIVE/NOTICE`, `LIVE/licenses/` |
| Geometry Forcing | https://github.com/CIntellifusion/GeometryForcing | `GeometryForcing/LICENSE` |
| Frozen WorldMem evaluator/VAE | https://github.com/xizaoqu/WorldMem and the recorded local evaluation revision | `references/worldmem/LICENSE.md` (S-Lab License 1.0), source headers |
| Rotary embedding implementation | https://github.com/lucidrains/rotary-embedding-torch | Original source attribution and `references/worldmem/ROTARY_MIT_LICENSE` |

Exact source revisions and the reference-file inventory are in `upstream_sources.json`. Changes provide dataset/trajectory adapters, numerical-failure reporting, portable setup, and shared scoring. The DecMem implementation is the authors' public Wan-based reference version, not their unreleased internal backbone.
