What Does The Quadratic-Weighting Barrier and Constraint-Based Realization (CBR) Examine?

This paper examines constraints on candidate quantum realization weights within canonical Constraint-Based Realization. It argues that a canonical weighting rule must satisfy Born-rule compatibility, refinement and coarse-graining stability, operational invariance, symmetry, normalization, regularity, and non-circularity; it does not claim a universal derivation of the Born rule.
