 ### 3D files (GLB)
-[`glb/`](https://huggingface.co/datasets/cfahlgren1/lowpoly-coder-4b-data/tree/main/glb) holds one `.glb` file for every row, except `stage1-valid-00036`, whose code throws an error when run, so its `glb` value is null. Each file is named after its source row: `glb/stage1-train-06570.glb` is the farm ox.
+[`glb/`](https://huggingface.co/datasets/cfahlgren1/lowpoly-coder-4b-data/tree/main/glb) holds one `.glb` file for every row, except `stage1-valid-00036`, whose code throws an error when run, so its `glb` value is null. Files are grouped by config and split, and named after their source row: `glb/stage1/train/stage1-train-06570.glb` is the farm ox.
 - **How they were made:** each row's `response` code was run unchanged through [`export_glb.mjs`](https://huggingface.co/townbox/lowpoly-coder-4b/blob/main/export_glb.mjs) from the model repo (Three.js r180). The result has one named node per mesh, flat shading and base colours only, with no textures.
 - **Validation:** the 60 sampled rows' files, copied from the original repo, pass the Khronos glTF validator with 0 errors and 0 warnings. Their mesh and triangle counts match the renders above.
-- **Source row:** those 60 files also record its row in `asset.extras.source`: dataset, revision, config, split, id, category, prompt and the SHA-256 of the row's `response`.
