This paper presents the complete theoretical architecture of TEG-Blue (The Emotional Gradient Blueprint), an integrative framework mapping how the nervous system organises human behaviour across scales — from individual signal detection to collective dynamics. TEG-Blue synthesizes polyvagal theory, attachment theory, trauma research, social psychology, critical theory, and systems thinking into a unified architecture with four core components: (1) Four Foundational Models (M1-M4) mapping the Emotional Somatic Cycle — from signal detection (M1) through nervous system states (M2) to regulation capacities (M3) and awareness architecture (M4); (2) Twelve Frameworks (F1-F12) explaining the origin, development, and scaling of the cycle; (3) Emotional Tools — gradient-based practical instruments; and (4) AI Safety Infrastructure — structured schemas for contextual, state-aware assessments. The architecture is grounded in a two-system model: the Emotional Somatic System (ESS), which detects, evaluates, and generates physiological responses before conscious awareness, and the Cognitive-Logical System (CLS), which builds narrative from whatever data reaches it. Whether the interoceptive channel connecting these systems is open determines which path the Emotional Somatic Cycle follows: biological restoration (Path A) or cognitive override and accumulation (Path B).

1. Four Foundational Models (M1-M4): M1 maps what the nervous system detects and the physiological response it generates (signal architecture). M2 maps how the nervous system reorganises into different physiological configurations along a continuous gradient — four states: Safety & Openness, Threat & Defence, Strategy & Management, Power & Dominance. M3 maps whether the restoration sequence completes (Path A) or cognition overrides (Path B). M4 maps whether the person can perceive the cycle while it is running — three awareness capacities (RE, ER, SEA) on two biological substrates. 2. Twelve Frameworks (F1-F12): F1-F3 map individual biology and development. F4-F7 map what happens when individual patterns scale to collective systems. F8-F12 map restoration. The Regulation Thread runs through all twelve: when biological restoration is unavailable, the nervous system substitutes — at escalating scales, at escalating costs. 3. Emotional Tools: Gradient-based instruments showing how dimensions (empathy, accountability, confidence, integrity) express differently across each nervous system state. 4. AI Safety Infrastructure: Structured schemas designed to replace binary safe/unsafe classifications with contextual, state-aware assessments.

Two information systems run continuously in every human being. The Emotional Somatic System (ESS) detects environmental changes through the sensory periphery and organises a complete physiological response before conscious awareness arrives (10-500ms). The Cognitive-Logical System (CLS) operates alongside: language, reasoning, narrative construction (500ms+). The CLS does not distinguish between a complete data set and an incomplete one — it builds coherence from whatever data reaches it. The four nervous system states map onto this architecture through a structural distinction: Safety & Openness and Threat & Defence are ESS-led states. Strategy & Management and Power & Dominance are states in which the CLS is increasingly recruited into threat organisation — a qualitative shift, not merely an intensification. Interoceptive Self-Awareness (SEA) is the bridge: the capacity through which the CLS receives the ESS's physiological signals. When open, the person can register activation as information. When closed, the CLS operates without the body's data.

This document records the author's original intellectual contributions, distinguishing novel propositions from integrated research. Key architectural innovations include: the ESS/CLS two-system architecture; the Emotional Somatic Cycle (ESC) with Path A/Path B; the continuous gradient model; the ESS-led / CLS-recruited structural distinction; four patterns from one mechanism; same mechanism across all scales; Interoceptive Self-Awareness (SEA) as the gate; three awareness capacities on two substrates; and the models/frameworks structural distinction. Original terminology includes: Emotional Somatic Cycle, Path A/Path B, Interoceptive Channel, Biological Restoration, Cognitive Override, Restoration Substitutes, The Self-Sealing Property, Somatic Debt, False Coherence, Signal Replacement, Chronic State Organisation, State Flexibility, The Regulation Thread, The Signal-to-System Sequence, The Filter of Worth, Feeling-Identity Fusion, The Chronic State Invisibility Principle, Capacity Configuration Profiles, and Awareness Degradation Pattern.

The architecture has received initial empirical support through the validation study (DOI: 10.5281/zenodo.19472342). All four nervous system states were detected in natural language across 10,000+ posts. Complexity markers — operationalizing Interoceptive Self-Awareness (SEA) — were 78% higher in de-escalators than escalators. The study proved generative: the clustering result established the ESS/CLS qualitative distinction, the complexity marker finding established SEA as a distinct capacity, and the ownership-performativity observation established coherence without the body as a recognisable CLS configuration.
