gaussian_gcd_bezout_bounded_exists

Ordinary natural induction constructs Gaussian gcd and genuine signed Bézout coefficients for every valid pair; each actual Euclidean remainder strictly decreases the norm bound.

Inputs are genuine canonical signed-pair codes, not arbitrary naturals. Products start at the actual Gaussian identity, whose code is six. The factor list uses the proved prime-divisor property; irreducibility alone is not silently renamed primality. Uniqueness supplies equal lengths, a bounded bijection, and an actual unit at each match, including repeated factors. Units have empty factorizations and zero is excluded. Sorted primary representatives, Gaussian prime classification, and Eisenstein factorization are separate targets.
