Detector-Plane Imaging (DPI) introduces an instrumentation-grounded framework for understanding measurement and interference observability at the detector plane. The framework establishes that interference is encoded in a pre-detection coherence imprint and that detector architecture determines whether this structure is preserved or irreversibly lost. A central contribution is the QMCTB-01 benchmark, formulated as a detector-plane causality test using a near-field double-slit configuration with identical excitation and propagation. By isolating detector architecture as the only variable, DPI demonstrates that measurement outcomes are determined by coherence preservation at the sensor layer rather than by input conditions alone. Fringe visibility (VVV) is introduced as a measurable criterion, enabling a falsifiable distinction between detector regimes. Intensity-only detection yields no stable interference (V≈0V 0V≈0) due to phase loss, while correlation-preserving detection retains coherence and produces high-contrast interference (V≈1V 1V≈1). This framework reframes interference observability as a consequence of detector-plane information selection, grounded in coherence theory and consistent with established quantum optical principles. DPI operates at the instrumentation layer, where quantum and classical optics converge at the sensor plane, providing a testable and experimentally accessible model of measurement.
