The Invariant Pulse cannot be observed directly—it exists only in the moment of perfect release, that instant when a throw transcends technique and touches universal truth. In the Primal Realm it manifests as the hunting rhythm of apex predators; in the Clockwork Realm as the fundamental frequency of conscious calculation; in the Hollow Realm as the cadence of meaningful silence between voids. Discs that have repeatedly traced the Perfect Line begin to hum with harmonic resonance, their plastic carrying the memory of that unchanging beat. The Pulse strengthens when multiple Linewalkers achieve synchronization in proximity, creating cascading moments of collective cosmic alignment.

The Invariant Pulse marks the threshold where deliberate technique dissolves into unconscious mastery, where a Linewalker stops thinking about the Perfect Line and simply becomes it. Those who achieve sustained synchronization with the Pulse across multiple rounds prove they've internalized something deeper than physics—they've aligned with reality's fundamental rhythm.
