# Third-party notices

AccessPath contains a project-level 2D inpainting orchestration layer and a
small adapter for external visual-3D inference. It does not redistribute model
weights, upstream source trees, datasets, or derived image assets.

The project is inspired by prior work in amodal completion and visual 3D
reconstruction, then adapted to accessibility-scene masks, categories, quality
gates, and review outputs. Inspiration does not transfer authorship: an
external model remains an external model whenever the runtime calls it.

## External models and libraries

- **Amodal3R** is an independently authored visual-3D backend. The adapter in
  `tools/accessibility_3d_completion.py` imports its public Python package and
  defaults to the upstream `Sm0kyWu/Amodal3R` model identifier. Its source,
  checkpoint, and license remain those of the upstream project.
- **Stable Diffusion inpainting** is accessed through Hugging Face Diffusers.
  The user must obtain the selected checkpoint separately and comply with its
  model card and license.
- **SAM 3**, when used outside this minimal package to create mask proposals,
  is separately licensed and may require access approval.
- **Depth Anything V2** is the default depth/geometry diagnostic backend in
  the full launcher. **VGGT** is an optional alternative depth/point-map
  backend. Their code and checkpoints are separate downloads.
- **pix2gestalt**, **Open-World AMODAL**, and **Amodal Completion in the Wild**
  are not imported or executed by the AccessPath runtime; their URLs occur
  only in related-work/comparison metadata.
- PyTorch, OpenCV, Pillow, NumPy, ImageIO, Trimesh, Diffusers, Transformers,
  Accelerate, and Safetensors retain their respective licenses.

Renaming a wrapper or output does not transfer authorship or change any
upstream license. No local model cache, environment, credential, dataset, or
experiment artifact is included in this release.
