+  0.875 at τ=64 (64 mod 17 = 13, C(13)=C(4)=−15, −15/17 ≈ −0.882) vs a
+  PRNG baseline's 0.0205, i.e. 42.7× (≫ the 3× kill bar).
+  `gcd(17,τ)=1` guarantees a full-period permutation, NOT low
+  autocorrelation. So the "anti-moiré in concept space / friendlier to
+  `I-NOISE-FLOOR-JIRAK`" inference is **struck** — strong periodic
+  autocorrelation is if anything worse for weak-dependence rates than a

+  and OGAR D-QUANTGATE stay canon — the coprime walk QUANTIZES by
+  construction (bijective closure + WGSL-portable integer stride), which
