This note develops a controlled macroscopic analog of resonance-corridor formation within USP Field Theory. A vibrating plate with granular media and double-slit-style geometry is used as an educational and experimental testbed for corridor-compatible pattern formation. The document explicitly limits its claims: the experiment is a classical granular and vibration-system analog, not evidence for quantum equivalence and not a direct model of microscopic Delta-f behavior. Its purpose is to provide a reproducible protocol for studying visible resonance-corridor patterns under controlled drive frequency, drive amplitude, slit geometry, grain size, humidity, and imaging conditions. Version 1.2 adds a Scope and Limits statement, a required Minimal Data Sheet, a Methods and Controls appendix, predeclared analysis metrics, a detection rule, reproducibility requirements, and an image-analysis pipeline based on image capture, preprocessing, 2D FFT, radial averaging, contrast extraction, coherence-length estimation, and mode-stability reporting.
