The Charged Loop Has Rank Two on Physical16
The frozen messenger tensors force the generation-lifted one-loop correction to remain aligned:
Imaginary aligned coefficients are common right-handed rephasings and vanish
in the full weak-basis quotient. The remaining physical16 response has two
real columns: common up-sector and down-sector mass dilations.
Its exact rank is two on every sheet of the complete stored 1,210-sheet fitted ensemble. Four within-sector mass ratios, nine CKM moduli, and signed Jarlskog coordinate are unchanged, leaving fourteen unreached tangent directions.
Rank deficiency does not grant selector authority. The two dilation
coefficients remain free and may generate opposite responses from the same
flavor sheet. The charged loop is therefore source-derived aligned
backreaction and instrument enrichment, not a physical16 selector.
