These 23 cases are the canonical runtime's own zap_test.go, and they were living in a chain — chains/cpp/platformvm/test/zap_test.cpp — because that chain had hand-written its own copy of the wire and had to test it somewhere. The cases were always right. The second copy of the wire was the problem, and it is gone. They test this implementation now, unchanged in substance: every pointer floored at the header, a byte tail's offset unsigned so a sign-extended bit pattern dies on the end bound rather than aliasing backwards, a list length that cannot outrun the buffer it names, and the full 0xFFFFFFE0..0xFFFFFFFF sweep behind that last one. A wire rule belongs in one place, and its test belongs beside it.
