CORRIDOR NUMERICS Independent research and engineering by Mostafa Nasr, Giza, Egypt. Updated: 29 October 2026 PROJECT STATUS The CN-machine aperture bench is a digital design with a first physical build in preparation. No physical validation or achieved instrument accuracy is claimed. Fixed interchangeable apertures and a repositionable detector support a future measurement comparison. RESEARCH Geometry information and approximation cost in recessed-aperture transport. Working revision 7, 27 October 2026. Open working paper, not peer reviewed. Computational and analytic study within an ideal recessed-aperture model. Substantial AI assistance is disclosed in the manuscript. Paper and archive: https://doi.org/10.5281/zenodo.23216693 SOFTWARE Bench Studio 0.2 preview: plan a scan, run a labeled synthetic session, replay and export records. No hardware connection. Session data stays in the browser. A built local preview is downloadable from the software page.
