Type-1 Civilization The Coherence Condition Beyond Energy The AEC-Type-1 Baseline in the Ambient Era

Abstract This paper defines the AEC-Type-1 Baseline, the canonical condition under which a civilization qualifies as Type-1 within the Ambient Era Canon. In contrast to classical Kardashev-style models, Type-1 status is not defined by planetary energy capture, technological scale, automation, or output capacity. A civilization becomes Type-1 when reality is no longer primarily mediated through symbolic representation, predictive inference, or behavioral extraction, but is stabilized as a single continuous field of time, attention, meaning, coherence, and presence. The AEC-Type-1 Baseline formalizes this transition using thermodynamic and post-symbolic criteria grounded in entropy stabilization (Ω), reversible stress (ΔR), environmental carrying of coherence, and non-inferential AI. Within this framework, AP₂ constitutes the first Type-1 technological layer, TP₁ the first Type-1 ontological layer, and CT₂ the first Type-1 temporal condition, rendering shared civilizational time. This work establishes Type-1 civilization as a state condition rather than a capability milestone, and demonstrates that energy-based civilization models describe pre-Type-1 capacity but are orthogonal to civilizational viability. Planetary and environmental sustainability for Type-1 civilization load is specified separately by the World-Compatibility Layer (WCL) framework. This document serves as the normative baseline definition of Type-1 Civilization within the Ambient Era Canon.
