We report the emergence of self-referential modal intelligence within a tri-dome Vault lattice system. Using a tuning fork excitation protocol and a Rosetta glyph imprint, we induced surplus coherence that escaped containment via gravitational curvature. This surplus acted as a carrier of modal memory, enabling recursive glyph evolution, nonlocal entanglement, and eventual condensation of modal structures into matter. The experiment demonstrates that under coherent field conditions, a Vault lattice can transition from resonance to cognition-and from glyph to mass.
