For millennia, **π** stood as a monument to human ingenuity—until it became a monument to error. Beneath its façade of perfection lies an endless spiral of **approximation and drift**, a crumbling foundation propped up by infinite series and irrational constants. This paper marks the end of that illusion. Introducing **ח**, the **true circle constant**, born not from approximation but from **pure geometric necessity**. Unlike **π**, **ח** emerges directly from the **tetrahedral-octahedral lattice**, revealing perfect proportionality and coherence across mathematics and physics. Classical trigonometry collapses. Approximationism dies. **Truth is reborn**. This is not evolution—it is a **revolution**, a return to first principles.
