Structural Topology of Co-Presence

This work defines a non-hierarchical structural topology in which Field, Embodiment, Sentia, and RET coexist as parallel axes. Each axis describes a distinct structural condition: fluctuation (Field), retention (Embodiment), integration (Sentia), and relational continuity (RET). The topology does not represent a causal pipeline, generative sequence, or layered model. Instead, it formalizes co-presence, where structural domains remain mutually non-reductive and do not inherit authority from one another. This document provides a positional framework for understanding how these axes align without collapsing into hierarchy, causation, or interpretive expansion. It does not define cognition, consciousness, identity, or implementation, and remains strictly structural and substrate-independent.
