Enumerate all non-source cells with at most11 disjoint baseline-pair blockers, classify every unordered cell pair as compatible iff the union blocker graph has minimum vertex cover<=11, and save full edge file, degrees and hash. Independently reconstruct/audit graph before treating it as proof input; then use required deficient rows/columns and constructive matching cuts for a13-cell search if graph is tractable.
