## Statement

Under the explicit B + SU(5) embedding, the one-generation Standard-Model gauge anomaly sums vanish and the mixed U(1)-gravitational anomaly sum vanishes, and the Witten SU(2) anomaly is absent.

## Caution

Anomaly cancellation does not select the compact embedding or determine the number of complete generations.

## Primary source

Paper 1, §8, Local anomaly sums, PDF p.30: "In the left-handed Weyl convention the local anomaly coefficients all vanish (kernel-verified, cross-checked in house, A696):"
