"Pi-drawer" - The ultimate extractor of the real π

An incredible theorem for a unique and effective equation to determine the universal constant Pi π definite and definitive
After millennia of attempts to calculate the circle with all sorts of simulations, until recognizing an identity to π, and yet with results often different and disputable, all that was missing was to be able to ‘bring it out into the open’ to identify it with certainty and without any approximations.

 
This task was accomplished by the "Pi-draw­er", a ge­o­met­ric de­vice de­signed to lit­er­al­ly ex­tract from the cir­cle and per­form the ex­act cal­cu­la­tion of the re­al Pi con­stant, by means of a 4th degree pol­y­no­mi­al e­qua­tion, with ra­tion­al co­ef­fi­cients and a single variable.

 
The theorem was ultimately matured in four years from a first introductory publication "2x2=3.14" (2021) about the squaring of the circle, followed by several articles and evidences to point out the actual π against reiterated adaptations, but unable to demonstrate it.

The alleged impossibility of achieving the Squaring of the Circle has thus been overturned in the same context.
