Applies the Void Framework to the Sumerian ME system and King List as the oldest documented civilization-scale opacity architecture. The ~94-100 ME entries satisfy all three void conditions at ceiling (9/12 for the antediluvian complex, Pe=5.2, Phase IV). The Sumerian King List is reinterpreted as a Pe trajectory document encoding drift from Phase IV pandemonium (antediluvian, Pe=5.2) toward Phase II constraint configurations (Ur III, Pe=2.4, Void Index 5/12). The ME transfer episode in Inanna and Enki is mapped as a canonical D1-D2-D3 drift cascade. Positions Sumerian scribal culture as identifying void-structure harms 4,000+ years before modern regulatory frameworks.
