Test fixtures — real production artifacts

These are actual outputs captured from entropydrop.com (via the HAR from 2026-09-13), not synthetic test images. They let you validate stage 2 against ground truth.

How to use them

Load a *_render.png in the "Render → Skin (debug)" tab and compare your Space's output against the matching *_skin.png. The v104b pairs are the strictest test: your Space runs the public v104 parser, so output will be close but not identical — differences in hair, eyes and beard are the known weak spots. The SKING_DDJ_v54 pair is a useful older-model reference.

A correct result is:

• exactly 64×64, mode RGBA
• a non-empty alpha channel (extrema (0, 255)) — transparency encodes the outer layer, so an all-opaque result means the parser failed
• pixels aligned to the Minecraft UV grid (head at top-left 8×8 blocks, etc.)

License and attribution

Copyright © EntropyDrop / Shanghai EqualRank Technology Co., Ltd.

Every generation record in the HAR carries "license": {"code": "cc-by-nc-4.0"}, so these images are CC BY-NC 4.0 — attribution required, non-commercial use only.

That is compatible with a free public demo Space, but:

• keep the attribution in this file and in the Space README;
• do not use them in any monetised deployment, paid tier, or print service;
• do not relicense them.

If you would rather not carry third-party NC-licensed assets in your repo at all, delete this directory and remove the gr.Examples block from the debug tab in app.py — nothing else depends on it.
