-The Problematic Axiom: The conventional geometric curriculum requires students to accept that the constant for circle area (A = πr²) is both exact and unreachable/irrational, because it is derived from the error-prone polygon approximation method (Archimedes).

 The Proposed Solution (CGS): The Core Geometric System™ (CGS) provides a logically self-consistent alternative where the area constant is the rational number 3.2 (A = 3.2r²), derived from an algebraically proven Area Balance Axiom with the square.
