Primitive Geometry and the Constants π, c, and h: A Minimal Ontology for Closure Theory

Primitive Geometry and the Constants ππ, ccc, and hhh: A Minimal Ontology for Closure Theory presents the conceptual foundation of Closure Theory in its most compact form. Rather than beginning with particles, fields or spacetime, the paper proposes that the primitive objects of physical description are a transported hyperbolic invariant, a closed circular transport frame, and an intrinsic recurrence. From these, the paper argues that the constants ππ, ccc, and a unique elementary closure-action arise naturally within a common geometric architecture. The work deliberately distinguishes established structural consequences from conjecture, identifying the proposed relation between the elementary closure-action and Planck's constant as the principal open mathematical question. Intended as an accessible introduction to the broader Closure Theory programme, the paper provides a concise overview of its underlying ontology while inviting mathematical scrutiny and further development.
