Weighted centering subtracts an unweighted mean · case 04
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 | [[-4.0, -4.0], [4.0, 4.0]] | [[-2.0, -2.0], [6.0, 6.0]] | Failed |
