In Part 6 we introduced the foundations of multi-agent geometry. Now, with the machinery of Parts 11–12 (geodesics, path dynamics, velocity, acceleration, harmony gradients, and multi-level motion), we can describe complex, realistic interactions among multiple SGI agents and humans. Part 13 presents the advanced formulation of distributed reasoning, coordination, conflict, and emergent collective intelligence.

In Part 11 we introduced geodesics and semantic path dynamics. In Part 12 we expand this into a full kinematic and dynamic theory on Sⁿ—how meaning moves through time, how fast, with what forces, and under what modal regimes. This gives UPA a mathematically grounded description of psychological change, social evolution, and SGI reasoning flow.

In Parts 1–10 we established the geometric substrate of UPA: polarity (S²), multi-axis meaning (Sⁿ), learning on curved spaces, certification invariants, multi-agent geometries, novelty, hierarchy, and context modulation. In Part 11 we add the final essential piece: how systems move on these manifolds—the geometry of semantic motion itself.

Parts 1–9 established UPA geometry through polarity, multi-axis structure, learning on curved manifolds, certification invariants, multi-agent geometries, novelty/emergence, hierarchical embeddings, and context modulation. Now we reach the central evaluative concept of UPA geometry: harmony—the scalar or vector measure of viability, stability, balance, and integrative coherence.

Parts 1–8 built the geometric core of UPA: polarity (S²), multi-axis structure (Sⁿ), manifold learning, certification invariants, multi-agent geometry, novelty/emergence, and hierarchical embeddings. Now we move to one of the most powerful and subtle components of the system: context modulation, and its geometric expression through local vector fields and region-specific harmony laws. This is how…
