2676 — Full Theta Seam Gram Anchors the Positive Prime Følner Block

For the reflected seam history

$$h_q(t)={\bf1}_{0\le t\le q}\Phi(q-t),$$

its norm tends to the full source norm as $q\to\infty$. On normalized positive blocks along a prime orbit, all pairwise seam Gram entries are nonnegative. Therefore

$$\liminf_{N\to\infty}\|H_pv_N\|^2 \ge\|\Phi\|_{L^2(0,\infty)}^2>0.$$

Finite seam traces vanish on these blocks, but the independent infinite-rank seam state does not. Uniform control of phased packets is the lower-frame problem for the periodized Fourier-power symbol $W_p$. Its sign in the doubled Green residual remains a separate gate.
