about

nx_amo_payload.nx -- emit a bare-metal RV64IA test payload (.bin) that exercises the A-extension (amoadd/amoswap/amoxor/amoand .d, with signed operands) by threading a byte through a scratch word and writing each amo's OLD value to the 16550 UART -- the emitted stream spells "ATOMIC". Run the SAME .bin on the sovereign emulator AND real qemu-system-riscv64 -M virt: identical output = EXTERNAL-ORACLE proof of the atomics (mirrors the 72-byte boot-payload evidence).
