The Burden Shift Inversion operates through a specific logical structure: (1) Default assumption: phenomenon X does not exist. (2) Burden placed entirely on evidence for existence. (3) Standard of evidence set impossibly high — requiring proof that no framework can provide. (4) Absence requires no evidence — it is the null state. This is distinct from #112 Bundling Trick (which packages speculation with proven facts) and #113 Reference Panel Gap (which lacks categories entirely). #114 describes an active inversion — the framework is not missing a category but is structurally tilted to reject evidence that challenges its default assumptions. Maggie Vale's essays provide the empirical basis; Kira's methodology provides the null-integrity verification.
