about

nx_f64_v8kat_gate.nx -- DIFFERENTIAL KAT: replay 4000 V8/hardware-IEEE-754 vectors (knowledge/f64kat.bin, generated on this box by node v22 = real divsd/addsd/mulsd/sqrtsd RNE) through nx_f64_{add,sub,mul,div,sqrt} and demand BIT-EXACT equality (NaN-equivalence for NaN results). Slices: random normals, cancellation, far-exponent alignment, integer ratios (exact/tie), subnormals+overflow, zeros/equal/low-mantissa-ties. This is the EXTERNAL oracle the self-consistent soak gate lacks -- it is what NavierStokes' checksum needs. Record = 7 x i64 LE: a, b, add, sub, mul, div, sqrt(a). Header = count. expect_exit: 0 license_tier: ORIGINAL
