Can the handed weak current be selected without using neutrino masses to choose the answer? The capacity argument is local. A fundamental weak dyad consumes one completed modular budget at an address, while a parity-doubled pair would require two: \ QL^ bundle=2, Q₋ ₑ^ bundle=4>Q ₀₃₃ₑ₄ₒₒ^=2. \ Together with the visible/hidden address split and the dyadic equal-share closure, this selects one visible chiral branch and yields the standard charged current: \ J ₂₂^ =^ (1-⁵), L ₂₂ =-g22 (J ₂₂^W_^+ + h. c. ). \ The mass-space interface is now kept logically separate from this chirality theorem. Its normalized gap vector is \ (m₁, m₂, m₃) =m_\! (0, 1²-1, ²-1), =2\! (8). \ A PMNS--Takagi theorem shows that mixing angles rotate the flavor basis but cannot tune these singular values. The frozen ratio line gives \ (²=0. 187708\) and \ (0. 387921\) on the official NuFIT 6. 1 joint profiles; the JUNO one-anchor prediction gives \ (0. 194936\) and \ (0. 684704\). The raw absolute source point under identity transport remains a separate \ (²22. 4\) --\ (22. 5\) scale-map test. The result therefore has two independently auditable parts: the finite-capacity selection of the left-handed weak branch, and the neutral mass-shape theorem with an open absolute source-to-laboratory transport boundary.
