all-sanitized mid-tau medium-amp checkerboard defect excess +0.13633 +/- 0.00038 (95% CI [0.13560,0.13707], d=33.24, 100.0% positive-sign); checkerboard isotropy gain at the same target window +0.49262 +/- 0.00461 (95% CI [0.48358,0.50167], d=9.79, 100.0% positive-sign); checkerboard nonmonotone defect excess is +0.06094 +/- 0.00041 (95% CI [0.06014,0.06174], d=13.75), and the slow-minus-fast checkerboard defect gap is +0.00249 +/- 0.00027 (95% CI [0.00197,0.00301], 88.2% positive-sign); stored low-tau rows already show the anisotropy suppression trend, with spectral anisotropy at tau 140, amp 0.18 equal to 0.95948 for stripes versus 0.63223 for checkerboard pinning

CONFIRMED. Checkerboard pinning robustly increases defect retention while preserving substantially more isotropic structure than one-axis stripe pinning. In the target mid-tau, medium-amplitude window, defect excess is +0.13633 and isotropy gain is +0.49262, both with 100.0% positive sign consistency. The nonmonotone defect excess remains positive at +0.06094, showing that the effect is strongest in an intermediate pinning window rather than rising trivially with forcing strength, and the slow-minus-fast checkerboard defect gap is also positive at +0.00249. The data support a genuine checkerboard-induced defect-trapping regime in which coarsening pathways are blocked without collapsing the pattern into a strongly anisotropic stripe state.
