The 5D Dual-Vortex Attractor and White-Hole Torus Model: A Geometric Architecture Note for Model D, C-Branch Coupling, and 17+1 Layer Mapping

This technical architecture note documents a project-internal geometric model linking a five-dimensional dual-vortex attractor, a toroidal white-hole analogy, Model-D branch logic, C-Branch reservoir coupling, and a recurring 17+1 layer motif. The note does not claim exclusive priority over toroidal, vortex-like, tree-like, detector-like, or white-hole motifs in general. It timestamps and defines the specific way in which these elements are organized inside the broader Model-D research program. The model is presented as a geometric and topological organizing hypothesis. Structural comparators such as multi-layer detector architectures, Yggdrasil-like tree schemata, toroidal cosmological imagery, and online visual analogies are treated as comparators only, not as evidence. The note separates architecture, hypothesis status, symbolic resonance, and empirical support criteria.
