Linear Flavon Words Have Codimension One Response Capacity
At an exact nondegenerate CP-violating Yukawa witness, ten algebraically independent weak-basis invariants give the intrinsic response-rank ladder
Rank two is the aligned charged loop. Allowing the identity and three linear adjoint words independently in each quark sector raises the rank to nine. Allowing WP450's complete degree-two word basis raises it to the full intrinsic rank ten.
The linear layer therefore has conditional codimension-one tangent capacity. It is not yet a selector: its sixteen real coefficients are not derived or fixed by the charged source. The degree-two layer is a universal local carrier and restores fitting capacity rather than prediction.
The narrow progressive gate is to derive the linear-word coefficients independently of flavor data and test whether the rank-nine relation persists over the complete fitted ensemble.
