The Five Core Foundations

Narrative Coherence is the ability to maintain a continuous self-story connecting past, present, and future. It is the cognitive architecture through which a person understands themselves as a coherent entity persisting through time — not merely a series of disconnected experiences, but a continuous being with a history and a trajectory.

Without Narrative Coherence, the mind cannot integrate experience into a stable self-concept. The present moment has no context, past events cannot be located within a larger story, and the future has no continuity with the self that currently exists.

Perceptual Trust is confidence that one's interpretation of reality is accurate — that the internal model of the world corresponds reliably to the world itself. It is the foundational assumption that perception is trustworthy, that threat signals are calibrated, and that the environment can be navigated without constant re-verification of every sensory input.

Perceptual Trust maps directly to Karl Friston's Predictive Processing framework — the model in which the brain functions as a hierarchical prediction engine, continuously generating models of incoming reality and updating them based on prediction error. When Perceptual Trust is impaired, the prediction error signal is chronically elevated: the brain treats ordinary inputs as potential threats requiring urgent reinterpretation.

Emotional Legibility is the ability to accurately recognize, name, and interpret one's own emotional states. It is the capacity to read the system's own telemetry — to understand what the emotional output signal is communicating about the state of the Foundations and the demands of the current environment.

In UMA, emotions are not traits or moral indicators. They are the direct output signal of the Five Core Foundations in response to internal or external deviation from baseline. A system that cannot read its own signals cannot respond adaptively to what those signals are communicating. The emotion is the data. Emotional Legibility is the capacity to read the data accurately.

Relational Safety is a baseline sense of security in relational contexts — the foundational assumption that connection with others is possible without constituting an unacceptable threat. It is not the absence of relational risk, but the capacity to engage relationally without the nervous system treating connection itself as a survival threat.

Relational Safety maps directly to Porges' Polyvagal Theory: the ventral vagal pathway — the neurological state that enables social engagement, higher-order cognitive function, and emotional regulation — is only activated under conditions of perceived relational safety. When Relational Safety is impaired, the nervous system defaults to sympathetic activation (fight/flight) or dorsal vagal shutdown (freeze/collapse), making social connection neurologically unavailable regardless of the person's conscious intentions.

Existential Anchor is a sense of meaning, purpose, moral orientation, and values — the foundational framework through which experience is interpreted as significant rather than arbitrary. It is the cognitive and motivational structure that answers the question: why does any of this matter, and what am I oriented toward?

In UMA, identity is defined by the value structure held within the Existential Anchor. Across a human lifetime, behavior changes, memory degrades, preferences evolve, roles transform, and opinions reverse. The invariant — what is conserved across all of that surface variation — is the core value structure entrenched in early development. Identity is fidelity to that structure. The Existential Anchor is where that structure lives.
