about

nx_rv64_run_bin.nx -- generic loader: reads knowledge/hw/runbin.bin (a flat RV64 binary), runs it on the golden behavioral sim (full privileged CPU + UART), and prints the UART output as "SIMUART: <hex>". Used by the real-C conformance harness to run each gcc-compiled program on the sovereign emulator and diff vs QEMU. expect_exit: 0
