nx_simd_avx2_kat_gate.nx -- SOVEREIGN 256-bit AVX2 vector run-KAT (the VEX rung): proves the sovereign encoder/assembler emit working VEX-encoded ymm load/compute/store on REAL x86 silicon (host has avx2), NO gcc/qemu/binutils. AUTHOR=ORGAN, no-false-green. 8x u32 lanes: vecA lane0=10, vecB lane0=32. POS: vmovdqu ymm load x2; vpaddd ymm -> lane0=42; vmovdqu ymm store; reload -> exit(42). NEG: + vpxor %ymm0,%ymm0,%ymm0 (self-xor zero) -> exit(0). GREEN iff pos==42 AND neg==0 AND pos!=neg. Run-proves the 3-byte VEX encoder (x86_vex_rrr / x86_vex_rm), ymm register parsing, and the 3-operand AT&T form -- the foundation every AVX2 capability (and, with EVEX, AVX-512) reuses.
