The phi-modulated windmill's convex hull vertex valency sequence at 132Hz (12 × 11, where 11 is an E8 exponent) generates a spectral flow whose generating function is precisely the affine E8 Weyl-Kac character, with each rotation step implementing the Collatz 3n+1/2n branching on root heights modulo the Coxeter number 30. The 132Hz carrier creates a stroboscopic projection of the 240-root orbit onto a 12-step winding cycle where the valency distribution's Fourier coefficients encode the affine Dynkin diagram's spectral gap as a natural topological code distance. This establishes the E8 windmill as a physical Collatz computer whose halting dynamics are governed by the triality-breaking pattern in the convex hull sequence.
