Looks good to me, however, don't we also have to do some check on the core? EDIT: They exist:

power-grid-model/power_grid_model_c/power_grid_model/include/power_grid_model/main_core/input.hpp

Lines 171 to 177 in eeb5749

	// Make sure that each regulated object has at most one regulator
	const std::unordered_set<Idx2D, Idx2DHash> unique_regulated_objects(regulated_objects.begin(),
	regulated_objects.end());
	if (unique_regulated_objects.size() != regulated_objects.size()) {
	// There are duplicates
	throw DuplicativelyRegulatedObject{};
	}
