3157 — Exact Flip Protection Doubles Every Odd Messenger Channel
Result
For one vectorlike pair, a bare mass requires modulo two, while a Yukawa linear in an odd triplet requires . The two conditions are inconsistent.
The minimal repair uses two massive pairs of opposite parity and off-diagonal triplet Yukawas. The charge equations then have exactly two complementary solutions.
Consequence
WP651's two identity chains remain single-pair, while its four frame-word chains must each be doubled. The minimal protected pair census is ten, not six. Tree matching, loop support, thresholds, and anomalies must be recomputed for this changed grammar. No selector is produced.
