Collatz on the Trefoil Torus

(2,3)-Torus Knot — k = 729 = 3⁶ Branch Locus

The golden diagonal band is the branch locus: 23,268 cells where Syracuse trajectories visit, out of 531,441 total (4.07%). The bright band has hard cutoffs on both edges — cyan pure-even cells on the foliation side, red pure-odd cells on the far side.

Why the Trefoil?

The trefoil is the (2,3)-torus knot: it winds meridionally (powers of 2, even steps) and longitudinally (powers of 3, odd steps). Rational slope 3/2 = 1.500 approximates critical foliation log₂3 ≈ 1.585. The gap encodes the deficit.
