2275 - The Illustrative Z8 Flavor-Spurion Equation Is Component Data, Not a Quotient Selector (WP65)
An exact matrix satisfying (Y_{12}=(\chi_1+\chi_2)Y_{22}) is carried by a
rational common-left weak-basis rotation to the same Gram orbit with nonzero
component-relation residual. The scalar equation rigidifies a chosen
generation frame and fails physical16 descent. Repair requires full spurion
representations and a covariant joint vacuum-to-Yukawa map. Verification:
WP65, 5/5 exact gates.
