The Synthesis Anchor exists simultaneously in all three dimensions, appearing as organic neural branching in the Primal Schism, geometric tessellation in the Clockwork Schism, and structured absence in the Hollow Schism. It acts as a living lens that continuously refracts the Perfect Line into its three component interpretations while maintaining the underlying unity. The entity generates visible harmonic resonance—a tri-tonal hum felt across all dimensions—when a Linewalker successfully demonstrates cross-dimensional understanding. It displays stress fractures and dimensional static when the realms drift too far apart, serving as an early warning system for existential incoherence.

It acts as both bridge and test—enabling cross-dimensional perception of the Perfect Line while simultaneously measuring whether Linewalkers understand they're pursuing one truth rather than three separate goals.
