Use positive integer n=380, exact integer arithmetic function f(k)=a*k+b with a=18, b=1. F(m) sums f(d) over every positive divisor d of m. Inversion uses mu(d)*F(m/d); complete prime multiplicities determine mu, with mu(1)=1. Do not replace d|m by d≤m or use only prime/proper divisors. Omit divisor=1. Give (n, all_divisors, omitted_divisor, partial_divisors, complete_value, partial_value, f_n, incomplete_certificate, boundary).

Require the omitted value actually to divide n and the incomplete inverse to differ from f(n). Retain full/partial divisor lists and both sums. The fixed No refuses an incomplete certificate, not the correct complete inverse.
