nx_nishi_diskimg_test.nx -- x86 ladder R9 rung-2: the LOADER PIPELINE (disk image -> load -> run).
A real loader's job: read the kernel off disk into memory and jump to it. This builds a multi-
sector image (sector 0 = MBR with the 0x55AA signature; sector 1 = the kernel payload), MODELS the
load (copy the kernel sector from the image into a load buffer = what BIOS INT 13h / a real loader
does), and RUNS the loaded kernel on the sovereign emu (emu_x86_run_k) -- proving the whole
image->load->execute pipeline sovereignly (no BIOS, no qemu). KAT: MBR signature, byte-faithful
load, and the loaded kernel exits 42. HONEST SCOPE: the 16-bit BIOS disk-read code itself + real
boot = R10 (hardware); this proves the load+run model. No persistent-hardware writes (Rule 26).
