The Arrow of Time as Architectural Identification: Disciplined Formulation in a Coherence-Based Framework After a Failed Phenomenological Bridge

Methodological position paper on the treatment of the arrow of time in coherence-based theoretical programs. After the structural closure of the macroscopic phenomenological bridge between the coherence field C(x,t) and Margenau-Hill negativity (Zenodo DOI 10.5281/zenodo.20073982 and 10.5281/zenodo.20077155, May 2026), this paper articulates the architectural identification dt = -dC/Γ, the effective coherence-entropy bridge, and the four-fold epistemic filter (derivation, bound, approximation, correlation) adopted as universal pruning criterion. Includes methodological implications for AI-assisted theoretical programs: the five-element requirement for operational claims and the two-threshold rule for speculative sessions.
