For a three-site equal superposition, each site carries probability |ψk|2 = 1∕3. This is the per-site occupancy of a quark in a colour triplet. The value 1∕3 requires no postulate: it is the Born-rule probability of finding the fermion on any one colour site.
For winding m=1, the compression residual has off-diagonal entries with equal magnitude:
This is exact colour symmetry, emerging from the equal-superposition constraint and Theorem 1. No SU(3) symmetry is imposed.
What Standard Model language calls a “gluon” is the name given to the correlation between quark colour changes. The mixed symmetry of B for n=3, m=1 means this correlation has no self-contained symmetry class — see Section 8.
For winding m=0, the residual is purely symmetric: a spin-0, colour-neutral scalar with three-fold internal structure. Whether this corresponds to the physical Higgs boson requires derivation of the mass generation mechanism, which is open.
