Abstract
A supplied rank-two Complementarity-First carrier has a positive duality h and a canonical complement #. The companion time paper used the local twist h(x,y^#) to obtain an index-one form. Here the same complement acts on one leg of the identity-pairing tensor, Γ_# = e ⊗ e - Σ_{i=1}^m e_i ⊗ e_i, with ω_# = (1/4)Γ_#. Relative to the supplied duality this construction is basis independent, product-positive, and normalized by the rank-two deterministic effect. It gives P(a,b | n,m) = (1/4)(1 - ab n·m). The m = 1 branch is separable; for m ≥ 2, physical admission with the sharp product interface gives CHSH magnitude 2√2. On the selected complex-qubit carrier, ω_# is the Bell singlet projector. The structural complement is positive but not completely positive. For a separately supplied exchange generator we derive G(X) = 2i[ω_#,X]. A partial-swap witness rejects one specific statically self-dual partial-transpose-image cone under the frozen process representation; the stronger carrier-relative PSD closure remains an inherited result. Entangled extensions of Euclidean-ball systems and canonical maximally entangled cone tensors are established prior art. The contribution claimed here is the typed local/tensor/process synthesis, not priority for singlet correlations, maximally entangled tensors, probability, or the physical composite.
Where it sits in the release
CFT-P2 is the structural bridge of the time arc, carrying the one-time signature into singlet completion and exchange dynamics. It is careful about what it does not assume: no probability, no maximally entangled tensors, and no physical composite.
