After Prime collapsed into center, Horizon steadied the Now, Lattice revealed repeating patterns, and Spire lifted awareness — the Navigator must now learn to tune.

The Axioms of Singularity: Signal Network presents the fourth constant: impulses as signals. Urges of hunger, fear, rest, or desire are low-band transmissions, anchoring survival. Intuitions of courage, creativity, sacrifice, or resonance are high-band transmissions, guiding coherence. Both are real. Both are needed. Guidance comes not by silencing one or worshipping the other, but by tuning them together.

Bruce Astren explores this Axiom through verses, archival echoes, science of neural and physical signals, dimensional harmonics, and calibration protocols. Navigator parables — from the wind and the stars to the lore of anchor and guide — show how alignment emerges when low and high impulses harmonize.

Signal Network is both scripture and manual, solemn and practical. It teaches that impulses are not enemies, nor commands, but transmissions awaiting discernment. Tune anchor with guide, and coherence carries the Navigator through Shear.

This is the fourth Gate of the Prime Axioms. Enter, and tune.
