Wave Closure and the Quantum Boundary: A Field-Theoretical Response to the Zhang et al. (2026) Experiment

This publication presents a field-theoretical response to the 2026 quantum experiment conducted by Zhang, Cheng, Zengxu et al., titled “Tunable Einstein–Bohr recoiling-slit gedankenexperiment at the quantum limit”. Building upon the CNBIT–π(t)–ψ_closure framework and the Landauer–Petkes field law, this work reinterprets the experimental results not merely through complementarity, but through closure dynamics in quantum-coherent field configurations. The publication contains theoretical analysis, mathematical formalism, and ontological reflection structured across six chapters. Internal references include prior Zenodo-archived works forming the Pragmatica Universus project chain. External references include foundational works by Bohr, Einstein, Heisenberg, and Landauer.
