about

nx_dxbc_exec_gate.nx -- D2 proof, EXTERNALLY GRADED: execute the REAL fxc-compiled arithmetic shader (knowledge/arith_shader.cso = "return c*2.0 + 0.5", a mad) on known inputs and grade the float32 output bit-exactly against the shader's known semantics. If ANY operand-decode or execution bit is wrong, the output won't match -> this validates the whole D2 path (operand decode + register I/O + mad) end-to-end. license_tier: ORIGINAL expect_exit: 0
