This release presents PIUM v1.3 with an integrated measurement-facing extension (v1.4). The Phase Interference Universe Model (PIUM) is a unified ontological and interpretive framework in which all physical phenomena arise from phase and amplitude configurations of a single universal wave field, Φ(x,t). Matter is interpreted as phase-coherent, self-closing wave configurations, while detection is understood as a resonant configuration response of measuring systems rather than wave–particle conversion. The original v1.3 document remains unchanged and provides the complete foundational ontology of the model.The newly added v1.4 extension does not modify any existing content, equations, or assumptions. It is appended as a clearly separated interpretive layer addressing measurement consistency and gravitational phenomena. PIUM v1.4 examines the compatibility of the model with:– the Weak Equivalence Principle,– classical and post-Newtonian orbital dynamics,– gravitational-wave observations,while maintaining full consistency with General Relativity and the Standard Model at the level of established predictions. No new particles, forces, parameters, or predictive equations are introduced. PIUM is not proposed as a competing theory, but as an ontological substrate beneath existing formalisms, intended to clarify conceptual structure without altering mathematical frameworks. The extension also outlines limited, non-predictive interpretive connections to selected open observational tensions, strictly within current experimental bounds. This work is intended for researchers interested in foundational questions of measurement, gravitation, and wave-based ontologies. Critical analysis and empirical challenge are explicitly welcomed, while all textual authority and versioning remain under the sole authorship of the author. Author contact:szabolcs.krehlik@gmail.com
