# Third-party notices for vendored protocol definitions

`imageService.proto` and `config.fbs` in this directory are copied verbatim from
the **Draw Things Community** repository:

- Source: https://github.com/drawthingsai/draw-things-community
- Files: `Libraries/GRPC/Models/Sources/imageService/imageService.proto`,
  `Libraries/DataModels/Sources/config.fbs`
- Retrieved: 2026-08-04
- Licence: **GPL-3.0**

These files are redistributed here under GPL-3.0 and remain subject to it.

## Scope

- The vendored files above, and the Python stubs generated from them by
  `setup.sh` (`imageService_pb2.py`, `imageService_pb2_grpc.py`), derive from
  GPL-3.0 sources. Treat them as GPL-3.0.
- `dt_client.py` and `render_court.py` are an independent client that speaks the
  protocol. Draw Things' own guidance permits a separately distributed client
  under another licence. If this project is ever redistributed, state that
  client's licence explicitly rather than leaving it implied.
- **Card artwork is not affected.** Images produced by running the model are
  output, not a derivative of the client or the protocol definitions, and are
  not placed under GPL-3.0 by this dependency.

## Model checkpoint

`qwen_image_2512_bf16_i8x.ckpt` is a converted build of Qwen-Image-2512, which
upstream is Apache-2.0 (https://huggingface.co/Qwen/Qwen-Image). Apache-2.0
carries no non-commercial restriction. The conversion to Draw Things' `.ckpt`
format was not done by this project, so record the provenance of the exact
checkpoint before shipping commercially — its server-side SHA-256 is captured in
each render's JSON sidecar.

## Copyright position on the artwork

Per U.S. Copyright Office guidance, purely AI-generated material is not itself
protected by copyright; protection attaches to sufficiently creative human
authorship — modification, arrangement, and human-authored elements.

This is why the project treats every generation as **concept material only** and
builds human-refined vector masters. To preserve that position, keep editable
masters and their revision history as evidence of human authorship.
