This paper documents the maturation of the Emotional Indicators of Compromise (EIOC) from its origin as a diagnostic instrument into the foundational primitive of emotional-layer governance. EIOC introduced the first security-coded vocabulary for emotional drift, affective anomalies, and relational posture deviations in agentic systems. Over time, the instrument expanded into a governance-safe detection layer, then into the substrate of Emotional-State Security (ESS), and ultimately into the drift-responsive architecture and operator-layer pedagogy that define emotional-layer governance physics. This lineage paper establishes the canonical evolution of EIOC and anchors its role within the broader discipline. It documents six developmental stages — from diagnostic primitive to unified governance field — and establishes that EIOC is not being replaced by subsequent frameworks but absorbed upward into the architecture it enabled.
