Freeze the yeast network and a protein-disjoint split

Freeze the yeast network and a protein-disjoint split

Choose a public yeast protein interaction network, record its version and release date, and split the edges so that no protein in the test set appears in any training edge. Log every removed self-loop and duplicate. Deliverable: A split manifest with protein and edge counts, an exclusion log, and a statement that the split alone predicts no interactions.
