+Proof. Step 1 (kinetic decomposition). At each bond e = (x, y) write
+the chord q_x - q_y in harmonic and anti-harmonic parts:
+
+  q_x - q_y = P_H(q_x - q_y) + (1 - P_H)(q_x - q_y),
+
+where P_H is the harmonic (spatially smooth) projection of
+Section 3.2. Expanding the square,
+
+  (b/2)|q_x - q_y|^2 = (b/2)|P_H(q_x - q_y)|^2 + HS_t(q_x - q_y),
+
+where HS_t is the truncated Hessian-of-tangent form of Section 3.4
+directly attached to the anti-harmonic content. Both terms are
+nonnegative (the harmonic square trivially, HS_t by the convexity
+of the sigma-model action). The free (harmonic) part is the one
+playing the role of the Gaussian kinetic energy in the block
+integration.
+
+Step 2 (truncation). The kernel governing the harmonic square is
+the free block kernel K_h of Section 2, which decays exponentially
+in the lattice distance at rate exp(-c |x| / (log H)^2). Truncating
+at radius D_1 = O((log H)^2) introduces
+
+  |truncation error| <= C_L exp(-c D_1) + O(chord^2)
+
+per site, absorbed in X_rem. We thus have

+  X = - sum_{e in Z^2} Y_e + X_rem,
+
+with Y_e := (b/2)|P_H(q_x - q_y)|^2 + HS_t(q_x - q_y) the truncated
+direct energy.
+
+Step 3 (properties of X_rem). X_rem is a sum of kernel tails (each
+bounded by C_L exp(-c D_1)) and Taylor corrections from the
+truncation. Uniformly in the configuration,
+
+  |X_rem| <= C_L v.
+
+Each term of X_rem is Lipschitz in the spin under dsigma-metric,
+with bounded derivative, so for q, q' differing at n sites,
+
+  |X_rem(q) - X_rem(q')| <= C_L n.
+
+Step 4 (lower bound on Z). Restrict the integral defining Z to the
+neighborhood
+
+  Cap_v := { q : |q_x - q_y| <= c' for every neighbouring bond (x,y) }.
+
+On Cap_v, HS_t(q) = 0 at every bond and the harmonic square is
+bounded by (b/2) c'^2 per bond. So the integrand e^{-sum_e Y_e} is
+at least exp(-C_L c'^2 v). The normalized product-of-area measure

+[q_0^1 q_x^1]. The two limits (12.3)-(12.4) and Theorem 12.1's
+hierarchy S^(s) are the same convergence in different coordinates;
+we prove them together.
+
+Step 1 (uniform tail). By Theorem 6.3 (slab decorrelation) at
+beta = beta_s(N), with the physical mass squared m = c/X(beta)
+and the KT identity log xi_beta = 2 pi beta (so xi_beta(N) ~ L^N
+= 1/a_N up to lower-order corrections), the depth-N fine
+two-point function satisfies
+
+  | C_N(x) | <= C_L exp( - c |x| / L^N )               (a)
+
+uniformly in N, s in [-gamma/2, gamma/2], and x in Z^2.
+
+Step 2 (L^N-rescaled limit). Let u = x/L^N and define the
+rescaled two-point function C_N^{(phys)}(u) := C_N(u L^N). By
+Section 8's joint-moment convergence (uniform in the trajectory
+by Proposition 10.1) and the uniform tail bound (a) (which
+absorbs the L^N-lattice-to-continuum approximation, uniformly
+over u on compacts), C_N^{(phys)}(u) converges uniformly on
+compacts to a limit C_phys^{(s)}(u). By construction this limit
+is the two-point function of the S^(s) hierarchy appearing in
+Theorem 12.1. The higher moments follow the same argument with
+the 2m-point functions and the 2m-fold Riemann sums; combined
+they identify the full hierarchy S^(s), finishing Theorem 12.1.
+
+Step 3 (chi and xi scalings). Substituting the Riemann sums:
+
+  c_N(s) := chi_beta(N) / L^{2N}
+         = int_{[-R,R]^2} C_N^{(phys)}(u) du + O(1/L^N),
+  d_N(s) := L^{-4N} sum_x |x|^2 C_N(x)
+         = int_{[-R,R]^2} |u|^2 C_N^{(phys)}(u) du + O(1/L^N),
+
+with R -> infinity as N -> infinity. Uniform convergence in Step
+2 (and the tail bound (a) for |u| > R) gives
+
+  c_N(s) -> c(s) := int_{R^2} C_phys^{(s)}(u) du in (0, infinity),
+  d_N(s) -> d(s) := int_{R^2} |u|^2 C_phys^{(s)}(u) du in (0, infinity).
+
+The lower bound c(s) > 0 uses C_phys^{(s)}(0) = 1/3 (internal O(3)
+covariance: the short-distance limit of the component correlation
+is 1/3 for unit spins averaged on S^2), and the upper bound uses
+(a).
+
+Step 4 (scaled means). From Step 3:
+
+  chi(s) := lim chi_beta(N)/L^{2N} = c(s) > 0,
+  xi(s)^2 := lim xi_beta(N)^2 / L^{2N} = d(s)/(4 c(s)) > 0,
+
+so xi(s) = sqrt(d(s)/(4 c(s))) > 0, and xi_beta(N)/L^N -> xi(s).
+
+Step 5 (continuity in s). By Corollary 10.2, for s, s' in the
+window with |s' - s| small,
+
+  | beta_s(N) - beta_s'(N) | <= C|s' - s|(1 + o_H(1)).
+
+The two-point function C_beta(x) is Lipschitz in beta on
+[H/2, 2H], with Lipschitz constant L_lip bounded uniformly in N
+and x by Griffiths-type inequalities. Therefore
+
+  | C_N^{(s)}(x) - C_N^{(s')}(x) |
+    <= L_lip |s' - s| (1 + o_H(1)),
+
+uniformly in N and x. Substituting in Step 3's integrals and
+using the uniform bound (a) to control the tails gives (12.5).  []
