Part I: The Life Definition

All formal machinery in one Part. The Parity Bridge Theorem identifies the weak sector’s unique parity violation as the sole polarity seed for self/non-self distinction. τ-Distinction and SelfDesc define the two predicates whose conjunction is Life; the Layer Separation Lemma proves this is genuinely E₂, non-reducible to physics. The Life Loop Class formalizes metabolism, the 4+1 Sector Template classifies all Life forms, and the Seven Hallmarks are derived as theorems. Predictions by Absence—virus, neutron, neutron star—establish falsifiability. Cross-sectoral foundations complete the framework before any biology.
