Indifference Before Density

This article develops a structure-genetic reconstruction of continuum order as a pre-discrete condition of mathematical continuability. It argues that the density of the Cantorian continuum is not foundational, but a projective mathematical expression of a deeper indifference of difference. The paper introduces C_{SG} = \langle i^-, d, i^+ \rangle as a triadic minimal structure of continuability and interprets the real numbers as symbolic explications of continuum order rather than as its ground.
