Vector centering divides by the signed coordinate sum · case 03
Vector centering divides by the signed coordinate sum.
Case contract
Return the L2-unit vector of v minus its scalar coordinate mean; a constant or empty vector returns empty.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
