"""Build the dataset's parquet shards under `data/test-*.parquet`.

The output schema MUST match the canonical schema (PLAN.md §1.2):

    Features({
        "path":  Value("string"),
        "audio": Audio(sampling_rate=16000),
        "label": ClassLabel(names=["bonafide", "spoof"]),

`notes` is a JSON string and MUST contain a unique `utterance_id`. Audio MUST
be 16 kHz mono. Resample at build time.

After building, validate with:

    speech-spoof-bench validate-dataset <this-dir> --skip-submissions
