Spinors and fermions

How spinors on $Y$ become fermions on $X$. The observer never gets 14D fermions on $X$; they get a pulled-back slice of a 14D spinor, decomposed by the tangent/normal split.

Can chirality emerge without imposing a Weyl condition

“Chiral on $X$” is a statement about the pulled-back spectrum in a torsion background, not a constraint pre-imposed on $S_Y$.

Axial torsion as a chirality filter: the mechanism

Axial torsion shifts the effective spectrum so one handedness wins the ground state.
