Scaling (K, P) to Exact Universal Constants.
Bridge Structural $(L, T)$ to SI Units.
$C_i = f_i(K, P)$ Analysis.
Mapping to Planck and SI Scales.
Computing Magnitude at $10^{-x}$.
Measured vs. Derived Validation.
Numerical Fixed Reality.
This stage completes the transition from structural geometry to numerical reality. It demonstrates that the values we call "fundamental constants" are fixed by the density and stiffness of the substrate.
FINAL STAGE STATEMENT
All physical constants, including their numerical values and units, arise as necessary consequences of substrate parameters K and P, and match observed physical reality without arbitrary input.
