I.D18 — Algebraic Lemniscate
L defined as the bipolar spectral algebra H_tau = A_tau^(B) x A_tau^(C) with crossing point and polarity involution sigma. The algebraic pre-geometric definition of the lemniscate boundary. Geometric form S^1 v S^1 emerges in Book II. Earned from prime polarity, omega-germs, and split-complex discovery.
