Correct canonical URLs and pseudonymization language; add citation guidance, archive checksums, reviewer-facing method boundaries, and an explicit pre-mint DOI gate. Audio shards and row-level data are unchanged.
Add one privacy-minimized reviewer-facing document that maps public F/M speaker labels to author-reported regional backgrounds, summarizes the distribution, and explicitly states that these are not verified dialect annotations. Direct respondent names and the source image are excluded.
fix(viewer): define canonical train val test splits
Configure Data Studio to load only the canonical row-level metadata projection. Add deterministic Parquet files for train/val/test and exclude heterogeneous auxiliary CSV tables from the default viewer configuration. No audio TAR objects are changed.
refactor(data): standardize validation split as val
