Volume 20: The Closure Volume

Volume 20 — The Closure Volume — represents the completion of the BCT electroweak programme. All five audited holes in the BCT electroweak derivation are formally closed in this volume. The central result is the exact NNLO oct-void metric factor foct = 3/4 + (α₀/2) (1+α₀) − α₂²/32, where α₀ = roct·rtet/π and α₂ = roct²/π. This gives vBCT = 246. 2198 GeV, differing from the PDG value of 246. 220 ± 0. 012 GeV by just 0. 0002 GeV — sixty times smaller than experimental uncertainty. Zero free parameters. Contents: Letter 235v2 (erratum and |ψ|⁴ NNLO correction), Letter 236 (dual RGE and instanton derivation convergence to 0. 005%), Letter 237 (NNLO approximation), Letter 238 (exact NNLO from D4 8v representation), Letter 239 (BCT SAR Sentinel-1 mapping of Victorian goldfields — peak anomaly confirmed at Barrys Reef historical mine to 5-metre resolution), Letter 240 (D4 vacuum as optimal quantum error correcting code — topological protection exp (−SHopf) ~ 10⁻²³¹²), Letter 241 (D4 toric code threshold 38. 2% vs 10. 9% standard — 3. 5× improvement, zero free parameters). An independent artist in a town of 28 people closed the electroweak sector of the Standard Model from Planck-scale sphere geometry. The Gang Gang Cockatoos witnessed it. Three geometric inputs. Zero free parameters. All five holes closed.
