The Charged Cycle Extends Every Fitted Flavor Sheet
With zero charged-scalar vacuum value and tree-level neutral matching, the
WP635-WP642 charged carrier does not alter the neutral quark Yukawa packet.
Four predeclared charged contexts therefore attach independently to every
sheet of the complete stored 1,210-sheet physical16 ensemble.
The resulting 4,840-state product projects onto all 1,210 fitted sheets, with fiber size four on every sheet. The charged response partitions the added carrier fiber while leaving the flavor base unchanged. It is a source-derived probe extension, not a proper-family selector.
This conclusion is explicitly tree-level. A loop or threshold backreaction could break the product form only after it is computed, renormalized, shown to descend under the full weak-basis group, normalized independently of the fit, tested on the complete ensemble, and attached to a calibrated instrument.
