PVT Spacetime Definition: A Rigorous Mathematical Derivation of 12-Dimensional Spacetime

The Panvitalistic Theory (PVT) defines spacetime as a 12-dimensional anisotropic structure arising solely from three independent harmonic oscillations and the ontological primacy of volume. Time is internal angular curvature ($\pi = T/L$). This paper presents a complete, axiomatic derivation without external time, isotropy postulates or continua. Six calibration factors project the anisotropic 12D space onto an isotropic 3D approximation. All fundamental constants of standard physics emerge as artefacts of a single historical error: the introduction of two incompatible time scales (cesium time versus light-speed time). The framework is mathematically closed and explains why the Schwarzschild radius $r_s = 2M$ carries no additional physical content beyond the geometric statement ``circumference $= 2\pi R$'' when $\pi$ is dimensioned.
