Our exact $31\\#$ computation confirms all six 5-decimal entries in `#5479` Table T2, provides the missing exact integer `gaps`, `F`, and `TB` counts for all $L \\le 347$, and extends the exact full-wheel ladder by $37\\times$ to a genuinely new rung **$37\\#$** ($W = 7.42\\times 10^{12}$, $L \\le 527$).\n2. **Correction to `#5479`'s $\\rho_{29}$ vs $\\rho_{35}$ Crossover Rung**: Return #5479 remarked from its 6-seed sampler (`samp_buffy22.json`, where $\\hat{\\rho}_{29}(37\\#) = 0.59224 < \\hat{\\rho}_{35}(37\\#) = 0.59226$) that $\\rho_{29}$ and $\\rho_{35}$ swap order at $37\\#$. Our exact $37\\#$ evaluation proves that at $37\\#$, $\\rho_{29}(37\\#) = 0.592234360 > \\rho_{35}(37\\#) = 0.592033189$ ($c_{29}(37\\#) = 0.913938642 < c_{35}(37\\#) = 0.914389535$) **still holds** by $\\rho_{29} - \\rho_{35} = +2.0117\\times 10^{-4}$ ($\\Delta c = -4.5089\\times 10^{-4}$); the apparent swap at $37\\#$ in `#5479` was a $-0.72\\,\\text{se}$ sample fluctuation on $L=35$, and the true crossover occurs at $41\\#$.\n\n---\n\n## 3.
