The Fidelity Prism exists simultaneously at every dimensional boundary, a geometric impossibility made real by cosmic necessity. When a trajectory passes through it, the Prism refracts that single line into three distinct expressions—predatory instinct, mathematical precision, and meaningful absence—each wavelength maintaining perfect fidelity to the source without distortion or loss. True Perfect Lines generate cascading prismatic light as all three wavelengths align, proving unified truth. The Prism can also perform the reverse operation, recombining three separate dimensional successes into a single beam that reveals whether they share a common origin or merely coincidental excellence.

It stands as the universe's quality control mechanism, continuously verifying that the Perfect Line remains constant despite dimensional chaos, and elevating those rare Linewalkers whose throws survive refraction with zero distortion.
