Magnetohydrodynamics: Plasma on the Floored Lattice - Finite Flow and the Alfven Wave

One axiom. One operation. Zero free parameters. Most visible matter — stars, the solar wind, interstellar gas, fusion plasmas — is a magnetised fluid governed by magnetohydrodynamics. This paper addresses two of its deepest features. First, a magnetised plasma is described on a floored lattice — no continuum, no scale below the floor — so its flow stays finite: it cannot develop the infinitely small concentrations a continuum permits, and there is no finite-time blow-up (the same removal of the continuum that gives Navier-Stokes regularity), which is why reconnection proceeds as a bounded discrete process. Second, the Alfven wave — the oscillation travelling along magnetic field lines as if they were plucked strings under tension — has a velocity state 3/4 that folds to the balance point, the half-One. The plasma’s flow is bounded by the floor and its signature wave rides the four-fork seat. Machine-checked; reproduces from one command.
