public enum ColumnRoleRemarks
Column roles are dataframe-owned metadata used by higher-level statistical, machine-learning, and transformation APIs to interpret columns without changing their typed column keys or vector storage. Schema objects expose the role values captured in a snapshot for inspection only.
