about

nx_simd_sse_shuf_gate.nx -- SOVEREIGN 128-bit pshufd run-KAT (rung R2+R3: 3-OPERAND assembler + packed dword shuffle), on REAL x86 silicon, NO gcc/ qemu/binutils. AUTHOR=ORGAN, no-false-green. Proves (a) the assembler now parses a THIRD operand (the prerequisite for pshufd AND all VEX/EVEX 256/512-bit ops), and (b) pshufd routes lanes by its imm control byte. src=[11,22,33,44] (4x u32): POS: pshufd $2 -> dst lane0 = src[2] = 33 -> exit(33). NEG: pshufd $0 -> dst lane0 = src[0] = 11 -> exit(11). GREEN iff pos==33 AND neg==11 AND pos!=neg (distinct => the imm genuinely selects the lane, and op0=imm/op1=src/op2=dst threaded correctly). Completes the sovereign 128-bit integer SIMD surface. license_tier: ORIGINAL
