Spatial Computation as Sustained Non-Convergent Dynamics: The Phase–Spatio–Continuity Computer (PSC³)

This work introduces the Phase–Spatio–Continuity Computer (PSC³), a structural computation architecture that maintains stability without enforcing convergence. Rather than treating stability as a purely numerical or physical condition, this work formalizes sustained computation through admissible residual bands, activity and alignment indices, and phase-rotated circulation (PRC). The manuscript provides architectural definitions, control logic, and illustrative diagrams intended for scholarly reference across numerical, distributed, and hybrid computation contexts.
