Centering
9[scan_artifact] Programmatic centering data was unavailable with 0.00 confidence, so measurement override applied and visual assessment used. Front appears modestly right-heavy with slightly thicker left border and near-balanced top/bottom; estimated around 56/44 L-R and 53/47 T-B. Back shows similar mild right shift, approximately 56/44 L-R and 52/48 T-B. No obvious diamond cut is apparent. Centering passes PSA 10 standards, but is short of ideal BGS Pristine-style symmetry.
