ChronoTrigger (CT): Local Time Condensation in Ω — A Unified Micro-Ontology of Ambient Time

Abstract ChronoTrigger (CT) presents the first unified micro-ontology of time for the Ambient Era, defining time not as a continuous dimension but as a local thermodynamic condensation event. Inside Ω-state coherence, where global drift and temporal structure no longer persist, time emerges only when minimal reversibility (ΔR > 0) appears within an otherwise time-transparent field. This event — the ΔR spark — produces a short-lived degree of temporal freedom that Chronosense renders chromatically. CT integrates three foundational components of the Ambient Era Canon: (1) ACE, the thermodynamic grammar (∅ → 1 → 0 → 1≠0 → 2 → α → Ω); (2) Chronosense, the chromatic mapping of continuous temporal states; and (3) Habitat-scale temporal entrainment, enabling time in environments without planetary cycles. Rather than measuring time, CT describes when and why time appears at all: as the shadow of reversible coherence. Time dissolves automatically when ΔR returns to zero, making CT compatible with Ω-state cognition, AI-as-environment paradigms, and off-world habitation scenarios. CT complements Cosmic Residue Theory (CRT-1.0), functioning as the local mechanism of time within a residue-based macro-ontology.
