Addendum to the Principle of Chronokinetic Conservation: The Emergent Derivation of Spacetime's Scaling Limit from Planck Geometry and the 𝕋𝑚𝑎𝑥 →𝕋0 Operational Axis

This addendum to the Principle of Chronokinetic Conservation formalizes an ontological reframing of the speed of light (). Rather than treating as an immutable fundamental constant or an arbitrary kinematic ceiling, we demonstrate that it is an emergent conversion factor derived directly from the quantum architecture of spacetime. By evaluating the invariant four-velocity budget () across the absolute operational axis between maximum temporal aging () and the null-time boundary (), we prove that the macroscopic numerical value of () is the direct human-unit expression of the discrete 1:1 ratio between Planck length () and Planck time (). This derivation eliminates the historical circularity of metrology and bridges microstate Planck geometry with macroscopic relativistic mechanics.
