SEAM.E8.DISCRIMINATOR.01
SEAM.E8.DISCRIMINATOR.01
The empirical/structural DISCRIMINATOR bundle (2026-06-30; mode D of the v347 closure-mode classification) -- concrete FALSIFIABLE kill tests separating the claimed seam=(E8)_1 from the nearest c=8 rival SO(16)_1=(D8)_1. v347 lists four closure modes; mode D is 'test the consequences', realised here as sharp discriminators. [E]/[X] PRIMARY/GSD DISCRIMINATOR: |det Cartan(E8)|=1 (ONE primary, holomorphic) vs |det Cartan(D8)=SO(16)|=4 (FOUR primaries 1,v,s,c); torus GSD = #primaries = 1 (E8) vs 4 (SO(16)) -- a seam with GSD>1 / >1 superselection sector falsifies (E8)_1. [E]/[X] CURRENT/THETA DISCRIMINATOR: level-1 current count dim E8=248 vs dim SO(16)=120; the E8 lattice theta has 240 norm-2 roots (=112 integer + 128 spinor, computed) vs D8's 112 -- the affine current spectrum and lattice theta DIFFER; the edge current multiplicity (248 vs 120) is observable. [E] c=8 IS NOT A DISCRIMINATOR: both nets have c=8 (the v277 ambiguity), so the central charge alone cannot decide; only the order-4 mu4 condensation + det K=1 (the genus-1 statement, SEAM.S3.MODULAR.01/v90) selects E8. [E] NON-VACUITY: the discriminators all fire on the rival (det 4!=1, currents 120!=248, roots 112!=240). [X]/[C] VERDICT: the (E8)_1 seam carries sharp falsifiable signatures distinct from every nearby c=8 net (mode D of v347 realised as concrete kill tests); SEAM.EQUIV.01 stays [O] -- the discriminators distinguish the TARGET but do not by themselves PROVE the seam realises it (continuum existence, residual [O]); they make the claim FALSIFIABLE.
Recorded status: E8 vs SO(16) kill tests [E]/[X]: mode D of v347 realised as discriminators -- torus GSD 1 vs 4, level-1 currents 248 vs 120, lattice theta 240 vs 112 norm-2 roots; c=8 alone does NOT decide (v277), only det K=1 (genus-1, v90) selects E8. Falsifiable: a seam with GSD>1 falsifies (E8)_1. SEAM.EQUIV.01 stays [O]
