"""v71 -- the SIMPLE solution of the R-bridge (gate #3): the quark RATIOS are integer
Plucker readouts of the lattice operators R (det=rank E8=8) and Q (det=N_fam=3); NO
transcendental monodromy solve is needed.  (Following the principle: look for the simple
complete solution first.)

The flavor operators on H_1(P^1\\mu4)=Z^3 are integer lattice maps whose determinants are
compiler atoms:
    det Q = 3 = N_fam,  det K = 4 = |mu4|,  det R = 8 = rank E8 = h(D5),  det L = 20,
    product = 1920 = |W(D5)|;   SNF(R)=diag(1,1,8), SNF(Q)=diag(1,1,3).

The discrete SELECTOR STRATUM S_{8,Q} = {det R=8, SNF(R)=(1,1,8), Spec(Q_+)={1,2,3}} is now
fully DERIVED -- det R=8 and SNF from the lattice, Spec(Q_+)={1,2,3} from the D4-equivariant
geometry (v69).  By Readout Rigidity (v49) the quark ratios are CONSTANT on this stratum:

    c_u/c_d = g_car*||Pl(K)||_1/(N_fam^2 * Delta_Q) = 5*11/(9*13) = 55/117,

with 11 = 1+4+6 (Pascal, v45) and Delta_Q = 13 (a Q/Plucker invariant; reads 8+5 = rank E8 +
g_car = N_fam^2+|mu4| = det R + g_car -- the one not-uniquely-atomic number, flagged honestly).

=> the R-bridge for the RATIOS is closed COMBINATORIALLY (integer Plucker data), with no
transcendental monodromy.  The only genuinely transcendental piece (U_point = full uniqueness
of rho*, i.e. the ABSOLUTE amplitude normalisation) is an anchor -- the same nature as the one
dimensionful scale -- NOT needed for the ratios.  The earlier monodromy machinery (v19-v49) was
over-engineering for the ratios.
