# GhostStack WF-06 Flux Fill R&D Runtime

This repository is a separate model bundle for GhostStack workflow **WF-06 —
REFRAME / EXTEND**. It is authorized only for non-production R&D technical
qualification. It is not commercially production-ready.

The bundle contains only the four model files required by the frozen WF-06
ComfyUI API graph. The source repositories, revisions, paths, byte sizes, and
SHA256 values below are the authority for each component.

## License boundary

The Flux Fill model is licensed by Black Forest Labs Inc. under the FLUX.1
[dev] Non-Commercial License. This bundle is for GhostStack non-production R&D
technical qualification only. Commercial or client production use is not
qualified by this repository.

Recipients must review and comply with the included upstream license materials.
No conflicting terms are imposed on the model files. No GhostStack source,
workflow JSON, client files, prompts, secrets, or proprietary recipes are
included.

## ComfyUI placement

Copy the four bundle files into the matching ComfyUI model folders:

```text
models/diffusion_models/flux1-fill-dev.safetensors
models/text_encoders/t5xxl_fp16.safetensors
models/text_encoders/clip_l.safetensors
models/vae/ae.safetensors
```

The authoritative GhostStack WF-06 workflow remains in the GhostStack source
repository and is not copied into this model bundle.
