Abstract
Sanity Is Signal reframes mental stability not as a subjective or cultural construct, but as a lawful function of coherence across space and time. Drawing from the CODES framework and Resonance Intelligence Core (RIC), this paper introduces Phase Alignment Score (PAS) as the primary metric for distinguishing high-coherence (sane) states from low-coherence (insane) emissions. We present a deterministic geometry of sanity as signal, noise as structural drift, and psychospiritual clarity as a function of lawful resonance. Sanity is shown to be an emergent condition, not a diagnosis — measurable through ΔPAS, ELF loop behavior, and symbolic field alignment. Includes typology of six PAS-indexed states of mind and mapping of key historical figures by coherence fidelity. This is not a metaphor. Sanity is the output of structured resonance. And it can be known.
