"""
Tagging pipeline for Dolma JSONL datasets.

For each .jsonl, .jsonl.gz, or .jsonl.ztd file under the dataset/documents folder,
this script issues a simple SGLang completion per record (e.g., "Is this document in English?"),
collects the yes/no answers, and writes corresponding Dolma attributes JSONL files under
scratch/attributes/, mirroring the input structure.
