 YOLO labels beside each tile image, keeps a deterministic ratio of empty
 negative tiles, and records `yolo_tile_dataset_summary.json` with
 `positive_tile_count`, `negative_tile_count` and skipped negative tile counts.
+It separately records configured, retained and empty validation sample slugs;
+this keeps a holdout that lost every tile to quality filtering visible without
+pretending it contributed evaluation data.
 `--min-label-visible-ratio` drops labels where only a small clipped fragment of
 the original building bbox is visible inside the tile; this reduces noisy
 tile-edge labels in overlapping-tile datasets. Use `0` for legacy behavior.
