E8 HULL FORBIDS THE 126 (2026-06-17): the E8 audit hull supplies exactly {1,10,16,45} for SO(10) -- turning the scalaron-match '16-Higgs over 126-Higgs' selection into an algebraic statement. The carrier D5(+)A3 = SO(10)xSU(4) is a rank-8 subalgebra of E8 via SO(16); the adjoint 248 branches as (45,1)+(1,15)+(10,6)+(16,4)+(16bar,4bar) = 45+15+60+64+64 = 248 (SO(16) split: 120 adjoint + 128 spinor = spinor_SO10 (x) spinor_SO6). (1) [E] ranks 5+3=8=rank E8. (2) [E] dims sum to 248. (3) [E] the SO(10) reps in the hull are exactly {1,10,16,45}; the 126 (dim 126) is ABSENT -> the renormalisable 126_H is algebraically forbidden if fields are E8-hull reps, and 10+16+45 is E8-supplied, not fitted. (4) [E] MULTIPLICITY CAVEAT: only ONE (45,1) and ONE (1,15) in the 248 -> the minimal E8-allowed content (one 45) is proton-MARGINAL, a sharp falsifiable constraint. (5) [O] the field-content principle ('TFPT fields are E8-hull reps') + the NCG inner-fluctuation complement (v250).
