This document collects refinements, clarifications, and extensions to the Principia Kosmoplex (https://doi.org/10.5281/zenodo.17861153). The framework matures through application and dialogue, certain interpretations deepen while others require correction. We document these evolving insights to maintain coherence across the growing body of work. Key developments include: (1) the geometric interpretation of the factor 20 as triadic connection topology (7 + 7 + 6), (2) the comvoxel architecture as the fundamental unit of 8D↔4D projection, (3) the 31 = 20 + 11 decomposition of the dark sector, and (4) experimental signatures of structural integers in particle physics data.
