## Statement

The earlier renormalization claim treated Yukawa and gauge running as fully protected by Artin without a diagram-by-diagram internal-generator census.

## Caution

This scope withdrawal does not deny associativity for two-generated subalgebras or refute the separately specified lepton–photon sector.

## Primary source

Appendix A, §A.7.8, Generic cross-block containment gap, PDF p.153: "for the generic cross-block Yukawa trilinear (three independent split-octonion entries, Paper 6) that containment is not established — momentum conservation constrains momenta, not the number of independent internal octonionic directions"
