Public Interface Visualization for Visible-Body Proportion Observation: BPI Calculator and BG-10 Coding Layer v0.5

This public archive presents a visual reference interface for exploratory visible-body proportion observation using the BPI (Body Proportion Index) framework and the BG-10 observational coding layer. The figure demonstrates a simplified public-facing calculator interface exposing only:- UD (Upper Difference)- LD (Lower Difference)- BG (Balance Gap)- BG-10 observational coding structure The interface is intended for educational visualization, longitudinal observation discussion, and exploratory methodological reference. BG-10 coding levels are presented as simplified descriptive references for discussing proportional discrepancy between upper-body and lower-body spread relative to the waist transition. Lower coding levels indicate smaller relational discrepancy and stronger proportional balance continuity, while higher coding levels indicate broader relational divergence requiring wider contextual review. This archive does not disclose protected interpretation infrastructure, proprietary calibration systems, adaptive interpretation logic, or non-public S-Scale architecture layers. The figure is provided for public scholarly discussion, concept archival purposes, interface visualization reference, and interdisciplinary exploration. This archive is observational, exploratory, non-diagnostic, and intended solely for educational and methodological discussion. Version:v0.5 — Public Interface Visualization Archive Open for interdisciplinary discussion and future refinement.
