+# Codex Validation Tiny 20260531
+
+Synthetic four-row dataset used to validate the dataset-add and Arena display workflow.
+
+## Overview
+
+Contains two bonafide and two spoof one-second synthetic audio clips generated locally.
+
+## License & redistribution
+
+CC-BY-4.0 for the synthetic generated audio in this validation dataset.
+
+## Schema
+
+| Field | Type | Description |
+|---|---|---|
+| path | string | Stable archive-relative path, unique within dataset. |
+| audio | Audio(16kHz mono) | One-second generated WAV audio. |
+| label | ClassLabel[bonafide, spoof] | Index 0 = bonafide. |
+| notes | string (JSON) | Contains `utterance_id`. |
+
+## Quick Start
+
+```python
+from datasets import load_dataset
+ds = load_dataset("Slenser0/CodexValidationTiny_20260531", split="test")
+```
+
+## Stats
+
+| n_total | n_bonafide | n_spoof | total duration |
+|---|---|---|---|
+| 4 | 2 | 2 | 4s |
+
+## Source provenance
+
+Generated by Codex as a temporary validation artifact for SpeechAntiSpoofingBenchmarks.
