TA11 closes the first Transport Architecture block (TA3–TA11) by establishing the primitive one-way transport scale ε = 1/320 and fixing the phase axis A = iσᵧ, both from the same oriented two-leg transport mechanism. The oriented distance-2 transport layer E₂ (Q₅) contains exactly 160 directed channels (80 unordered pairs × 2 orientations). Normalizing a unit closure defect against this layer gives \ δfull = 1/160 \. The branch-exchange involution Θ, established in T47/T50, splits this defect equally across two oriented legs, fixing ε = 1/320. By TA5, the observable round-trip phase coefficient is \ μ = 2ε = 1/160 \. The phase-doubling lemma establishes that the same two-leg mechanism that produces magnitude doubling also forces the phase axis. Each mediated leg contributes π/4, accumulating π/2 total. Purely real symmetric coupling produces no phase residue, \ Q = Qᵀ ∈ ℝ \ implies \ Im (Q) = 0 \ implies \ µ = ½Tr (QR) = 0 \, so nonzero phase requires oriented complex transport contributions. The two-leg accumulation forces the generator \ A ~ iσᵧ \. The T8–TA11 Bridge Lemma identifies the spectral ratio β/α with the primitive transport scale under three constraints: same defect source \ (δfull = 1/160) \, same two-branch splitting \ (ε = 1/320) \, and same perturbative normalization. This gives \ β/α = εₒne-way = 1/320 \, structurally derived rather than numerically inserted. The continuous phase closure theorem shows that iterating the one-way transport operator gives \ Tₚhaseᵏ = e^ (k/320) A + O (k/320²) \, with observable readout \ µₖ = sin (k/320) + O (k/320²) \, controlled for \ k ≪ 320² \. The primitive scale 1/320 thereby links the spectral ratio, one-way transport, phase generator, continuous-limit evolution, and observable sine-law readout in a single unified structure. Geometry supplies the defect scale. Transport supplies the phase structure.
