The Quantized Dimensional Cell in Gravitational Dynamics: GM, Keplerian Closure, and Dimensional Admissibility

This preprint presents a QDL admissibility theorem identifying the gravitational parameter μ = GM as a direct realization of the Quantized Dimensional Cell (QDC) dimensional form L^3F^2. The result is framed as a structural interpretation of standard Keplerian dynamics, not as a modification of Newtonian gravity or a numerical derivation of G. Physical constants are often introduced as numerical values to be memorized, but in physical modeling they serve a deeper structural function: they connect otherwise distinct dimensional sectors. The Quantized Dimensional Ledger (QDL) formalism represents dimensional quantities as integer-valued ledger vectors and tests constructed expressions against declared closure…
