⬡ Nuclear
V4 is a calibrated SEMF-class binding model (~1% period errors, downloadable script), not a zero-parameter derivation. T(2,3) is nucleon structure, not a proton-mass theorem. Live claims: /status.
V4 Engine Validation
Core Concepts
S³ 600-Cell Projection
The 120 vertices of the 600-cell section into an icosahedron (12), a dodecahedron (20), an inner icosahedron (12), and an icosidodecahedron (30). Those sections are geometry. Assigning them to a nuclide is a modelled reading.
V4 Nuclear Engine
Links to /software/v4-nuclear-engine for full docs. ~1% mean error across 116 elements. Calibrated to α-particle and deuteron binding energies.
Proton Structure
The proton is T(2,3): winding numbers p=2, q=3. T(2,3) is nucleon structure, not a proton-mass theorem; mass and charge are not a zero-parameter mint from the knot. The p/q ratio appears in the V4 engine constants.
Neutron Structure
The neutron is T(3,2): winding numbers p=3, q=2. Same cluster as the proton but with exchanged winding — the charge mirror that gives zero net charge.
Light Nuclei Simplex
A=2, 3, 4 on the S⁷ simplex. Triton 61/16, alpha 209/16, and the bond ratio 10/9 are packaging. Branch 2 does not mint the deuteron binding. U₀ stays open.
Nuclide Horizon
Heavy nuclei, Z ≥ 80. Cage 12+30=42 and lead horizon n_α=41 are packaging. The rhombicosidodecahedron is struck. Overflow addends stay open.
Deuteron Binding
An older Weber package. It is not the S⁷ simplex. The live A=2, 3, 4 reading is the light-nuclei page.
Proton–Neutron Mass Splitting
Why is the neutron 1.293 MeV heavier than the proton? From the T(2,3)/T(3,2) asymmetry in Weber binding energy.
Octonion Flavour Assignments
G₂ ⊃ SU(3) assignments for the 8D octonion structure. Maps octonion basis vectors to quark flavour. Open investigation: 8D assignments not yet frozen.
SHE Dual-Edge Package
Diagnostic superheavy maps: PRC‑A proton edge × L1 neutron firmness (dual3) × topo freeze hard edge. No BE/A island theorem; half-lives forbidden; mass-table promote not approved.
Drip Lines
Separation-energy edges as diagnostic maps (not free drip theorem). Hard freeze edge and dual firmness are separate; see SHE dual-edge package.
