Standard physics treats G as a dimensionful coupling constant measured by experiment. The framework gives a different account.
In Planck units, G = 1 by definition. Theorem 4 gives G = 1∕(8π) from the graviton flux argument. These are consistent: the normalisation ∥W∥∝M is not yet fixed by the framework independently of G. What is fixed is the functional form: V ∝−Mm∕R with the 1∕R dependence exact and the 8π geometric factor exact.
The value of G in SI units is a unit conversion between Planck units and human-defined units:
G = 1 in Planck units is the statement that the minimum-complexity orbital geometry and the minimum-complexity orbital frequency are mutually consistent at the Planck scale.
