Model::merge_nodes replaces merged nodes by their survivors in elements (node order kept, so face and edge tags hold) and in set node lists, moves a vertex tag to an untagged survivor, and refuses a merge that would collapse an element. fieldcraft_mesh::join::coincident_nodes / merge_coincident find the nodes within a distance of a lower-labelled survivor, deterministically. Meshing cell by cell and mirroring use them; node merging commands will too.
