Selector–Time Theory (STT): Ontological Architecture and Selective Temporal Dynamics — Version 2 (Refined and Extended Framework)

Selector–Time Theory (STT) proposes that time is not merely a descriptive parameter, but an active ontological operator responsible for selecting which coherences become real in the physical world. In contrast to Relativity, where time is treated as a geometric coordinate, and standard Quantum Mechanics, where it appears as an external evolution parameter, STT introduces the selective operator τ as a constitutive mechanism of reality. The theory is formulated around a minimal onto-temporal architecture Ω–Δ–τ–γ, clarifying the distinct roles of pre-time, liquid-time, and post-time as separate ontological domains. This Version 2 presents a refined and more cohesive formulation of STT, incorporating: • A clearer distinction between the Second Ontological Degree (admissibility domain) and the Third Physical Degree (observable domain) • Formal integration of CAL (Locally Adjusted Coherence) as a structural hardening operator • Improved terminological consistency across coherence, admissibility, and ontological stabilization • Expanded conceptual bridges with General Relativity and Quantum Mechanics • Enhanced internal coherence and structural clarity of the theoretical framework Additionally, this version includes computational experiments implemented in Python, along with output figures, providing reproducible evidence of the selective dynamics proposed by STT. This version supersedes Version 1 while preserving it for historical and scientific transparency.
