This record publicly defines BPI-R6, a six-coordinate relational profile for representing selected visible body-proportion relationships. BPI-R6 organizes six coordinated descriptive views: Upper Relational Contrast, Lower Relational Contrast, Mean Relational Contrast, Frame Balance, Directional Distribution, and Frame-Normalized Contrast. The coordinates arise from a shared relational measurement structure and are retained because each addresses a non-identical descriptive question concerning the relationships among the upper outer frame, waist, and lower outer frame. BPI-R6 is defined as a representation schema rather than a new measurement instrument, diagnostic system, body-type classification, body-quality score, or complete model of the human body. The six coordinates are mathematically related and are not presented as statistically independent factors or independent biological dimensions. Higher coordinate values, larger radial profiles, or more regular visual configurations must not automatically be interpreted as superior, healthier, or more desirable bodies. This record establishes the public identity, coordinate terminology, descriptive functions, scope, and interpretation boundaries of BPI-R6. It builds upon earlier public Body Proportion Index conceptual and relational definitions by organizing selected relational quantities into one coordinated six-coordinate profile. No new empirical dataset is introduced in this record. Invitation for Scholarly Dialogue Questions, brief comments, critical perspectives, and informal scholarly conversations are all welcome.
