-`configs:` is left empty in the frontmatter; HF auto-discovers a
-per-directory config from `data/<pair>/*.parquet`.
+Each language pair is one config (`bel-eng`, `cat-eng`) with everything
+under that pair pinned to `split: train`. The configs are listed
+explicitly in the YAML frontmatter so that HF's auto-split detection
+does not mistake filenames containing substrings like `-test-` for an
+actual test split.
