ABIVersion is 7, the go_bridge.h ABI in which ok says whether the result is the block's. The binding does not compile against a header that names another, and init reads the loaded library's gpu_abi_version() instead of panicking on it: against a library of another ABI, ExecuteBlock calls nothing and declines every block, and a result of another ABI is declined too, so the caller runs them on its own EVM. The native tests hold the library to that contract. A block of funded plain transfers runs on a GPU lane to TxOK at 21000 gas each, or is declined there when the host has no device, and a CPU lane declines it; a batch with code or calldata is declined on every lane. The opcode, bytecode and gas-parity tests ran code through the entry, which runs none, and are gone; the block-context and sustained-Metal tests run transfers. A test that needs a device skips on a GPU lane that declines. The tests that pin the build with no library linked moved to cevm_nolib_test.go, outside the native build, where they failed.
