2262 - One Mixed Gram Word Repairs the Measured-Ten Flavor Collision (WP57)
On the exact WP52 (\cos\delta=\pm4/5) hostile pair, the source-derived
weak-basis invariant (I_{11}=\operatorname{Tr}(H_uH_d)) takes distinct exact
values. One scalar mixed word therefore refines the measured-ten doublet into
two physical16 singletons without a reference port.
This repairs separation, not selection: both points remain admissible. The probe is indirectly instrumented by masses and CKM data.
