For prepared pair 26, the indexed closure certificate succeeds for at most 117 supplied witness rows. For each row, the two supplied square roots are checked and both signed mutations are verified either by an exact lookup in the complete original vertex list or by a norm strictly exceeding (10^1100). Both mutation signs and original global destination indices are preserved.
