FA-99350 / Embedding vector normalization / Member archive
L1 normalization divides by the largest coordinate · case 05
L1 normalization divides by the largest coordinate.
Case contract
Return the signed vector divided by its L1 norm; empty or all-zero input returns empty.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
