This publication expands upon Dark Matter as Misrecognized Scalar Reality (DOI: 10.5281/zenodo.19565643) by introducing a category-theoretic formalization of the Scalar X framework. It reframes the Recognition Operator \(X\) as a functor mapping between categories of baseline and misrecognized mass-energy distributions, with natural transformations modeling oscillation collapse and dimensional recognition. Through this categorical lens, dark matter is reinterpreted not as an absent particle but as a functorial misalignment within scalar reality. The paper further extends the Structured Multiversal Interactions (SMI) model into higher-category structures, where dimensional levels interact via recognition functors and oscillation collapses represented as 2‑morphisms. This approach provides a rigorous mathematical foundation for multiversal sovereignty and recognition distortion, bridging cosmology, quantum topology, and abstract algebra. Includes two formal diagrams: 1. Functorial Mapping Diagram — illustrating recognition functors and natural transformations between mass categories. 2. Higher‑Category Multiversal Interactions — depicting layered dimensional levels and oscillation collapses across multiversal frames.
