Exp Depinning Elastic Line 79
zeta_est 0.05007 +/- 0.00919 (d=5.44758, sign-consistent=100.0%); zeta_theory 1.26600 +/- 0.00000 (d=inf, sign-consistent=100.0%)
REJECTED. The measured roughness exponent (0.050) is 25x smaller than the theoretical prediction (1.266) for 1+1 dimensional elastic line depinning, and this discrepancy is highly reproducible across 948 seeds on 54 hosts (d=5.45, 100% sign consistent). The interface is effectively flat rather than rough, indicating the simulation never reaches the scaling regime where the depinning roughness exponent governs. This is likely a finite-size or finite-time artifact — the elastic line needs orders of magnitude more lattice sites or longer evolution to exhibit the expected self-affine roughening at criticality.
