Theta Collision Lifts to Signed Labelled-Current Coherence

Before winding-label aggregation, each theta summand carries the signed current

$$d\mu_{n,L}(t)=-\phi_n'(t)\,dt+phi_n(L)\delta_L(dt)$$

and

$$izH_{n,L}(z)=\int(e^{izt}-1)\,d\mu_{n,L}(t).$$

Only the codiagonal sum is positive:

$$\sum_n d\mu_{n,L}=-\Phi'(t)\,dt+Phi(L)\delta_L(dt)>0.$$

Writing

$$g_{n,L}(x)=\int\sin(xt)\,d\mu_{n,L}(t),$$

the double-zero collision is exactly

$$\sum_n g_{n,L}(x)=0, \qquad \sum_n g_{n,L}'(x)=0.$$

Thus scalar minimum phase is created after the same aggregation that erases the signed label information. The remaining theorem is a cross-label descent law transporting integral-square orientation through differentiation, oscillatory integration, and codiagonalization.
