Continuity Domain Demonstrations: Physics‑Grade Demonstrations of Continuity Geometry Across Scientific Domains

Paper 7.1 demonstrates the universality of continuity geometry across physics. Building on the geometric foundations of Paper 7, it introduces the Continuity Geometry Primitive (Co) as a substrate‑level descriptor of identity (I), curvature potential (K), and invariance (A). The paper presents demonstrations across microphysical, macrophysical, spacetime, chaotic, and topological domains, showing how Co injects into existing equations without dimensional conflict. Continuity transitions occur when curvature potential exceeds invariance, revealing shared geometric behavior beneath phenomena such as quantum decoherence, turbulence onset, singularity formation, chaotic attractor confinement, and topological identity persistence. Paper 7.1 completes the physics substrate required for the domain‑specific applications of Papers 10.2–10.10 and the operational substrate of Paper 10.11.
