1. Use the Prime-Coprime Fermat Form Only under Both Hypotheses

Use integer base a=3 and modulus=2, normalized residues in [0,modulus). Exact integer square-and-multiply computes powers; trial division checks primality. Every equality of residues here is a congruence modulo the stated modulus, not an unrestricted integer equality. The coprime form requires prime modulus and an invertible base; the all-integer form for prime p also allows p to divide a. Never cancel a noninvertible residue. Give (p, normalized_base, power_p_minus_1, congruence_certificate, boundary).

80. A Composite Can Pass a Fermat Test for a Chosen Base

Use integer base a=8 and modulus=561, normalized residues in [0,modulus). Exact integer square-and-multiply computes powers; trial division checks primality. Every equality of residues here is a congruence modulo the stated modulus, not an unrestricted integer equality. The coprime form requires prime modulus and an invertible base; the all-integer form for prime p also allows p to divide a. Never cancel a noninvertible residue. Give (modulus, base, prime, coprime, power_modulus_minus_1, boundary).

(561, 8, No, Yes, 1, converse_false_composite_can_pass_Fermat_test)

Verify the modulus is composite, the base is coprime and the computed (modulus−1)-st power is1 modulo the modulus. That is an explicit counterexample to the converse, not a proof that every base or every composite passes. The exact result, retaining the requested order, is (561, 8, No, Yes, 1, converse_false_composite_can_pass_Fermat_test).
