Grouped Color Deletion, Lasserre Exactness and Clique-Sum Locality for Rainbow Matching
Deleting k colors to place the residual augmented graph in a uniformly rank-r exact hereditary class yields Lasserre exactness at level k+r, with color-intersection graphs inducing clique-sum locality for blockwise algorithms on rainbow matching.
