This paper argues that civilisation-scale verification infrastructure would constitute the most significant structural change to humanity's relationship with knowledge since the scientific revolution. Two precedents frame the argument: the scientific method, which introduced a verification architecture for durable knowledge but operates at human speed; and SWIFT, whose geopolitical capture and fragmentation expose the governance failures such infrastructure must avoid. The paper examines what changes when verification operates at civilisational scale, the risks it introduces, and the choice between deliberate design and normalised unreliability. Recent work — including Google DeepMind's identification of multi-agent collectives as the ASI pathway hardest to control without shared infrastructure — strengthens the case that the verification question is not optional but definitional. This is the final paper in a twelve-paper series; the integration from deficit to civilisational infrastructure is its contribution. ---
