Abstract: Under analytic idealism, individual minds are dissociated perspectives within a broader field of consciousness. This essay asks what structural features such individuation must exhibit — and derives them generically, over every boundary in the nested architecture of finite mind: the dissociative boundary constituting a private perspective, the egoic boundary within it, complexes within that. Two axes fall out of the derivation: how much a boundary admits from what surrounds it, and how well the bounded interior organizes what is admitted. Because the derivation quantifies over boundaries rather than persons, permeability is boundary-relative — one parameter per boundary, composing in series where they nest — so the architecture the project's clinical model found is retrodicted as structural necessity. Two further constraints determine which configurations populate the experiential landscape. Stability, stated over total traffic across live channels, yields a taxonomy of persistence modes under which the clinic's sealed-but-persisting configurations are predictions, not problems. Generativity has two faces: structural preconditions a third person can specify, and an intrinsic constitution no extrinsic criterion satisfies — that exposure is suffered, that outcomes matter. Stratified across the nest, that distinction fixes where the constraints deliver verdicts and where they can only sharpen the question of interiority itself. The essay reads quantum outcome-level openness as the formal signature of the categorical limit between mathematical description and interiority, and names the framework's principled terminus: the intrinsic nature of mind-at-large prior to and beyond its own self-differentiation. The standard throughout is structural analysis under symmetric pressure, not metaphysical certainty.
