-# Dream-Cubed Human Representative Sample
-
-This directory is a deterministic, class-stratified sample of the Dream-Cubed Human dataset. It is provided for reviewer inspection of data quality; the full dataset remains available at https://huggingface.co/datasets/dream-cubed/DreamCubedHumanSample.
-
-The sample dataset for procedurally generated data is available at https://huggingface.co/datasets/dream-cubed/DreamCubedNatural.
-
-
-Depending on which commands have been run, the sample may include raw human-authored map chunks and/or compact processed train/validation examples. Processed examples may also contain natural biome chunks from the companion Dream-Cubed Natural release. Permission to release voxelized chunks from the human-authored maps was granted explicitly by the anonymized map creator for noncommercial research, but not for commercial products or reconstruction of the original maps.
-
-## Creation Procedure
-
-- Sampling seed: `67`
-- Last source mode added: `raw`
-- Raw target: up to `32` chunks per raw source label
-- Processed target: up to `128` chunks per label per split
-- Strategy: deterministic stratified sampling without replacement
-- Output: compact `.npz` raw samples and restored, unsharded processed `.npy` split samples
-
-Exact source paths, selected source indices, sample counts, and output files are recorded in
-`sample_manifest.json`. Processed split directories also include `source_indices.npy` and fresh
-`manifest.json` files. Dataset metadata files copied from nearby public dataset files are stored
-under `metadata/` when available.
-
-## Inspection Notes
-
-This sample is intentionally small and should not be used for model training or quantitative
-evaluation. It is meant only to help reviewers inspect file formats, labels, chunk tensors, and
-overall data quality without downloading the full multi-GB dataset.
