Parity: Physical Requirements for Spatial Distinction A Foundational Clarification

This paper provides a physically grounded definition of parity by stripping it of abstract coordinate inversion and grounding it in material reality. It shows that parity has physical meaning only when a system enforces spatial orientation through structure, constraint, and interaction geometry. Parity is therefore not an inherent symmetry of space, but a condition that arises when a material system can physically distinguish inverted interaction geometries and record that distinction. Where no such enforcement exists, parity is a formal description without physical consequence.
