The correctness sweeps only exercised the public Checksum dispatcher, so wherever it resolved to the gvisor fallback (non-AVX2 amd64, fallback architectures) the suite compared gvisor against itself and the AVX2 assembly went untested -- silently green. Per-arch export_test.go files now enumerate the hand-written implementations and every sweep runs against the dispatcher plus each of them, skipping with an explicit message when the running CPU can't execute one.
