Conceptual update:
- Simplified PMF incorporated in the Structural Intelligence Framework
- Entity is the common managed-object base class.
- Host, Sensor, Signal, Event, Knowledge, Agent, Interface, and Log are Entity subclasses..
Open object-oriented models for accountable AuI

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…

Parts 1–6 established polarity geometry (S²), multi-axis hyperspheres (Sⁿ), manifold learning, safety invariants, and multi-agent interaction. Now we turn to one of the deepest and most powerful consequences of UPA geometry: novelty—the lawful emergence of new distinctions, new dimensions, new identities, and new forms of intelligence.
