3190 — Full-Route Endpoints Falsify the Exchange Selector
Correction
WP676 established exchange invariance only for the internal two-messenger mass block. The independently typed entrance and exit currents couple to different bare fields, so holding those physical sources fixed breaks (A\leftrightarrow B). Exchange balance is therefore an internal-block rigidifier and erosion minimizer, not a source-authorized selector of the full flavor constructor.
Pole-basis result
On the balanced block, the frame fluctuation transforms as
It is pole diagonal. Hence the cross-pole (P_+\leftrightarrow P_-+n) transition vanishes and the WP674 bare-species cascade cannot be combined with the exact exchange explanation.
