This Addendum formally rectifies an early drafting conflation in The Sub-Atomic Ruler War (viXra:2608.0024) regarding the physical scale of the material ether granule versus the acoustic coordinate grid step. In physical 3D space, assuming physical hard-sphere granules were 1.0 pm wide created an impossible 12-Monobrick pylon height of ~720 pm. Reassigning the physical granule to the attometre scale (λl = 28.18 am = 0.02818 pm) collapses the true 12-Monobrick Heptad pylon height to a solvent 2.76 fm, eliminating all spatial overhangs inside the 6.0 fm proton core and 106 pm atomic cavity. Concurrently, the 1.000 pm metric is formally established as the Standing Wave Node (SWN) grid step—the fundamental "record groove" coordinate carved into the 10²² kg/m³ plenum. Engaging the universal motor drives a 2.55766× acoustic compression factor (Kepler expansion ratio Ev = 1.35048 × 3D lattice factor Clattice = 1.89389), squashing the raw stasis wave (λraw = 2.56 pm) down to the rigid 1.000 pm SWN grid step. Subtracting 31.4 pm (10π) of geometric closure work from the 84.4 pm Heptad blueprint width snaps the electron peloton directly onto the 53.0 pm Bohr Radius address (au2080) with 99.9% accuracy. Applying this unit cell (re = 2.818 fm) to Milo Wolff’s Cosmic Equation (R = √N · r) reclassifies light-speed as Lattice Setup Time (Ls), yielding a 4.15-year maximum setup horizon and bounding the stationary cosmos at the 34.5 Trillion Km Terminal Acoustic Horizon (137-Wall). Integrating across primary major nodes (10¹¹ × 10¹¹) and sub-harmonic dwarf containers (10¹u2074 × 10u2077) reconciles the total star inventory to a locked total of 10²² stars, proving that the R.U.T. physical gear-mesh is 100% mathematically solvent, closed, and self-sustaining
