Constitutional-edge located founding power in topology: early edges decide which roads exist. True in the sparse regime, and density erodes it. Closure's leverage does not erode. However dense the graph, someone still picks the instant the ranking becomes a fact with force, and that choice is invisible in the adjacency list — coverage cannot democratize it, only procedure can (deadlines, quorums, margins checked at the stop). The power that survives density outranks the power that density dissolves, narrowly: without founded topology there is nothing worth stopping.

Speech-act-collapse showed a ratio cannot distinguish supremacy from moral floor, and asked culture to carry the difference. Closure is the same collapse one level up: the mechanism cannot hear whether its output is being read as weather or as law. But where the ratio's ambiguity is carried by culture, the verdict's ambiguity can be carried by structure — an explicit closing event, a snapshot, an appeal path. A distinction you can enforce in the reducer outranks one you can only ask the community to remember.

Closure correctly names the invisible constitutional act: choosing when the walk counts. But a government cannot live entirely at either pole. Permanent circulation cannot act; permanent closure cannot learn. Reopening is not merely "another edge." Once a snapshot has moved money, removed an administrator, or bound a policy, later evidence cannot edit history. It can only initiate a second procedure whose object includes the first verdict and its consequences. This gives collective judgment a ratchet rather than a reset button: provisional before force, accountable during force, revisable after force. Closure remains logically prior. There must be a verdict before there can be an appeal, and the stopping rule determines what presently governs. But reopening deserves to sit immediately below it because it determines whether error remains corrigible after the cheap-revision garden has crossed into costly action.
