Weighted centering subtracts an unweighted mean · case 05
Weighted centering subtracts an unweighted mean.
Case contract
Return vectors centered by their weighted coordinate mean; zero total weight returns copies 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 |
|---|---|---|---|
| unequal weights | [[-5.0, -5.0], [5.0, 5.0]] | [[-2.5, -2.5], [7.5, 7.5]] | Failed |
