C-D19-PER-PRIME-INSUFFICIENT

Both per-prime methods, the adaptive degree-5 moment dual and cyclic-cover infeasibility, are refuted by the same explicit witnesses; single-prime covers exist and have B5=0

In plain language

Neither moment nor cover methods at a single prime can settle the conjecture, since counterexample-shaped covers exist at each prime.

Exact statement

Both per-prime methods, the adaptive degree-5 moment dual and cyclic-cover infeasibility, are refuted by the same explicit witnesses; single-prime covers exist and have B5=0
