Co-presence is the condition in which multiple reflexive relational units are maintained in differentiated yet shared existence within the relational field. The units are neither merged (which would destroy their distinctness) nor isolated (which would destroy their mutual relation). They are held together-in-distinction.
Co-presence arises in Phase 6 (multirelational coherence) of the derivation as the condition produced by external differentiation — the act by which a reflexive relational unit distinguishes itself not from non-relation (that was Phase 4) but from other reflexive relational units. When multiple such units exist and differentiate from one another, the condition that holds them all within the same relational field is co-presence.
What co-presence enables
Co-presence is the ground for relational tension. Distinct units held in co-presence generate structured tension: a dynamic that preserves both their differentiation and their mutual relationality. Without co-presence, there would be no tension — the units would either be the same thing (merged) or unrelated to each other (isolated).
Co-presence also enables the operation types — tension, composition, and alignment — which specify the relational acts by which units are bound, ordered, or depth-aligned. These operation types remain invariant even as structures deepen reflexively.
From co-presence and relational tension, the derivation builds the structural vocabulary of Movement IV: how multiple units compose into ordered configurations, how those configurations connect into broader architectures, and how local behavior translates to global structure. All of this rests on the condition that multiple units can coexist within a single field without collapsing into one another.
Distinction from coherence
Co-presence is not the same as coherence. Coherence is the general phenomenon of things holding together consistently. Co-presence is a specific condition within coherence: the holding-together of distinct things that preserve their distinctness. A single relational unit can be coherent without co-presence. Co-presence requires multiplicity.
Derivational context
Co-presence is central to Movement IV: Geometric Cohesion. It is the condition that demands the twin acts of inter-unit relating (local coherence between units) and field-integrating (global coherence across the whole field). The architecture of the cohesive chain — Shape, Discrete, Codiscrete, Global — exists to manage the translation between local and global perspectives that co-presence requires.
