τ-Neutron
The τ-neutron is the minimal stable ontic defect bundle on the toroidal T² fiber: the lightest persistent T² defect with non-trivial winding data, unpolarized (zero charge, zero isospin, balanced χ_±), and the first ontic particle in the τ-framework atlas.
τ-Definition
The τ-neutron is the minimal stable ontic defect bundle on the toroidal T² fiber: the lightest persistent T² defect with non-trivial winding data, unpolarized (zero charge, zero isospin, balanced χ_±), and the first ontic particle in the τ-framework atlas.
Categorical invariant. Minimal stable T²-defect bundle with non-trivial winding; unpolarized; first persistent ontic configuration in the τ-atlas.
