FA-99358 / Embedding vector normalization / Member archive
Zero embeddings become a fabricated unit vector · case 03
Zero embeddings become a fabricated unit vector.
Case contract
Normalize by L2 length while preserving input dimensionality; zero and empty inputs remain unchanged.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| zero pair | [1.0, 1.0] | [0, 0] | Failed |
