C02.2 · What this does not show

It does not derive three physical generations, a spin structure, a spinor-bundle map, a gauge assignment, or a mass interpretation. It does not assert that the full real quartic zero set equals the compact parametrized image. The normalized sphere map and its homogeneous extension are not used interchangeably. There is no verification here of the absent integral interface or of an unprovided banked Peirce basis.
