+# CoPeP Reviewer Sample
+
+This repository contains a compact deterministic sample of `anon2435/CoPeP` for
+reviewer inspection. It is intended for checking file format, schema, and example
+records without downloading the full dataset.
+
+## Contents
+
+- `train/train_sample.parquet`: deterministic stratified train-row sample.
+- `val/val.parquet`: full validation parquet from the anonymous CoPeP release.
+- `dataset_manifest.json`: sampling details, row counts, and limitations.
+
+The train sample preserves the main dataset train-row schema:
+`name`, `sequence`, `seq_hash`, `task_0` through `task_9`, and `row_idx`.
+
+## Sampling
+
+Rows are grouped by first observed temporal task, defined as the first true
+`task_0` through `task_9` column. Up to 10,000 rows are selected per group using
+a deterministic score derived from `seq_hash`, `row_idx`, and a fixed seed.
+
+This sample is not a drop-in replacement for the full dataset. It does not
+include task split files, because those files reference row indices in the full
+training table.
