The model identifies three primary neural-processing streams mapped onto the hand's major creases: the Head line (executive will), the Gut line (emotional-identity processing), and the Spine line (sensory input). A fourth circuit, the Apollo line, governs pattern-detection and perfectionism. We propose a typology of Gut-line morphology — Beam, Split, Segmented, Fused, and Fragmented — each predicting distinct decision-making styles. Using a machine-vision pipeline to generate objective morphological descriptions, we analyse three cases, including the lead researcher’s, finding alignment between Gut-line type and documented or reported life-trajectories. This work extends the Zero Code framework — in which we previously demonstrated Tier-9 exclusivity for lexical equilibrium — into the biometric domain, treating the hand as a stable morphological record of processing architecture. 1. Introduction Human palmar flexion creases form in utero and remain stable throughout life. While their embryology is well-studied, their potential as markers of neurodevelopmental predisposition remains unexplored. This paper introduces the Tri-Brain Hand Model, a topographic system that interprets these creases as outward maps of internal processing architectures. This approach parallels our earlier lexico-numerical research (Saxon Ventura Research Ltd, 2026), where we found that meaningful selection in language converges toward the constant 27 — a pattern now investigated in the domain of embodied cognition. To minimize subjective bias in feature description, we employ a machine-vision agent to generate sterile geometric descriptions of crease topology prior to typological classification. 2. The Model 2.1 The Three Primary Lines o Head line (Radial Longitudinal Crease): Associated with executive function, willpower, and vitality. o Gut line (Proximal Transverse Crease): Processes emotional valence, identity narratives, and "gut feelings." o Spine line (Distal Transverse Crease): Handles sensory input and reflexive reaction. 2.2 The Apollo Line...
