This submission presents a conceptual framework that interprets several open problems in quantum mechanics through the lens of the Unified Applicable Time (UAT) and Unified Causal Principle (UCP) frameworks. It does not claim to replace quantum mechanics; it offers a complementary geometric and thermodynamic layer of interpretation. The document identifies three manifestations of a single principle —irreducible fluctuation— at three scales: cosmological (7% thermal calibration margin), laboratory (force metric Rgeom = 0. 2791 from the 8-coil interferometer), and quantum (~0. 07% detector resolution limit). This principle provides interpretive bridges to: The measurement problem (collapse as saturation of the Ivancho limit, κcrit = 4. 978). Decoherence (information leakage governed by the irreducible fluctuation margin). Entanglement (geometric projection from higher-dimensional causal structures). The quantum vacuum (vacuum energy density predicted by the UAT cosmological constant derivation). Superposition (reinterpreted via the Causal Oscillation Hypothesis as a detector resolution artifact, not a real physical state). Negative tunneling time (Hartman effect explained by least-action paths in the Feynman path integral, with UAT/UCP providing the causal consistency condition). Limitations are explicitly acknowledged: UAT/UCP does not derive the Schrödinger equation, the Born rule, or second quantization. Whether the framework can be extended to these domains is identified as an open question for future investigation. The package includes the LaTeX manuscript. All referenced UAT/UCP works are publicly available on Zenodo with their respective DOIs.
