+
+`main` tracks the **v3** layout of the parent dataset: `cluster` is 6 columns and
+`cluster_extra` is 6 columns (`[_, momentum, vtx_x, vtx_y, vtx_z, is_primary]`),
+with vertices in the same voxel frame as the point coordinates.
+
+The previous v2-layout mini (5-column `cluster_extra`) is preserved on the `v2`
+branch.
+
+Events are the first 80/20/20 events of each split's parent shard with at least
+1024 points.
