trefoil protons · bipartite mesh — every contact p↔n, traction by construction · mass defect from the shadow
mesh —
in the mesh, each proton presents as a RING — wedding-band proportions, wide and flat — four very skinny strands twisting around each other as they run the band (the free proton's 6π trefoil, tightened at 1.83c; the mass is still the packed 1836 electron volumes, mp/me = 6π⁵). A neutron is the same band with its electron seated inside at the node, facing the bond — the electron is the mesh-maker. proton red · neutron blue. Shown representationally — the real strands are vastly finer.

One scale κ, fixed by least squares. The shadow-overlap is the mass
defect to ~8%. Residual: pure boundary overlap slightly over-binds the
light α-cluster nuclei and does not resolve the Fe peak — that fine structure needs the shared-electron
well depth (NP17), not geometry alone.
Geometry of the weave. The ideal trefoil's three tips sit exactly
120° apart, coplanar — the bowl a real strand pulls into is the over·under weave buckling out of
plane. That buckle is an angular defect, and Descartes fixes the total: a closed shell carries
720° — twelve 60° trefoil caps close an icosahedral shell (12 units · 12 vertices), which
is why the wire bowls and why nuclear shells want to be spheres. At the 1.83c seat the six windings
tighten onto their torus.
