about

nx_emu_arm64.nx -- sovereign aarch64 (A64) interpreter (NX-EMU). Mirror of nx_emu_rv64.nx for the third architecture. Flat guest RAM (vaddr==offset), NZCV flag engine, Linux aarch64 syscall surface (exit/write/read). NO qemu -- decode/execute is pure NishiLang per the Arm A64 ISA (the spec is the oracle). Register model: X0..X30 in x[], SP + PC as scalars, reg field 31 = XZR (read 0 / write discard). genealogy_id: arm_a64_isa_ddi0487 + linux_arm64_abi lineage_id: nishi_nx_emu_arm64_m6 license_tier: ORIGINAL
