Set-Theoretic Structure and Combinatorial Properties of the 6-Dimensional Hypercube (v8: 3-bit Q-axis with scalar mapping functions)

This paper defines a 6-dimensional structure obtained by adding a discrete label axis Q with 8 values (3-bit: c₁c₂c₃) to the 5-dimensional hypercube, and states the combinatorial properties derived from its set structure. The 3-bit Q encodes weak isospin (c₁) and color charge (c₂c₃). v8 adds Definitions 9.1-9.5 (scalar mapping functions f_Q^charge, f_Q^color, f_Q^iso and conserved-quantity mappings f_m^rest, f_m^curv) with explicit disclaimers on their abstract nature.
