- We extend our previous algebraic construction of three fermion generations in the complex Clifford algebra $\mathbb{C}\ell(10)$ by incorporating the Higgs sector. Using the $S_3$ family symmetry that permutes three algebraically distinguished fermion sectors, we construct Higgs components as right-action operators and extract the corresponding Yukawa coefficients by means of a trace pairing. This yields two first-generation Higgs doublets with the correct electroweak quantum numbers and a natural Type-II-like separation between down-type and up-type Yukawa channels. The $S_3$ action triplicates this Higgs sector, producing six Higgs doublets organised into $S_3$-orbits. In the exact $S_3$-invariant limit, the Yukawa sector retains its Type-II structure, while the generation-space Yukawa matrices are not diagonal in the algebraic generation basis. If electroweak symmetry breaking is implemented in the usual way, tree-level flavour-changing neutral currents are not expected in this limit.
