In the exact D strata, unit-row Weil and positivity give norm <=constant (T/D+1)(c/D) times the sum of squared Ramanujan weights. The ell,s,v weights have absolute value1.

Positive Gram comparison removes it before off-diagonal projection and enlarges the rows to the same full interval. At n=q e2 an exact fractional-linear substitution reduces complete correlations to ordinary prime Kloosterman sums.

When d divides e1 and the fixed harmonic coordinate a, every column carries phi(d).

Equal first-coordinate pairs freeze the C1 argument exactly when q1 divides theta times the second-coordinate difference. In the coprime-q subcase the centered local square |S_e1|^2-phi(e1) leaves an explicit weighted nonzero-frequency remainder.
