The formula for computing the b vector in round j incorrectly referenced a_hi instead of b_hi in the second term. Before: b ← b_lo · u_j^(-1) + u_j · a_hi After: b ← b_lo · u_j^(-1) + u_j · b_hi This ensures consistency with the protocol where each vector is computed from its own low and high parts during the folding process.
