a Starting from the original formulation of matter and gauge fields, b each truncated gauge link is split into two representations, one per half-link; each is equipped with a proper fermionic rishon mode ζ. c All the half-links are absorbed into the attached matter site, forming a gauge-invariant dressed site d whose Hilbert space spans all the possible gauge singlets.
