The package\u0027s advertised functionality is a trivial 5-entry frozen color constants map under the unscoped-looking @uwr scope (\"colors for the unified workflow runtime\") with an empty author field, consistent with a dependency-confusion / reconnaissance probe staged against an internal namespace rather than a legitimate library.\n",
