Feature Reproduction

No pretrained embeddings, model checkpoints, CondenGT-specific target tables, opaque feature caches, or pre-generated missing-count views are included. The missing-count views are deterministic transformations of data/raw/phase_diagram_original_scale.csv.

1. python scripts/prepare_missing_splits.py partitions rows by the number of NaN values across group_11–group_44 without changing the source rows. The generated views are intentionally excluded from metadata/file_inventory.csv. A changed pandas version can alter CSV byte formatting; validate the total row count (280,778), fields, and value equality when regenerating.
