Gradient style clipping expands a vector already under the norm bound · case 04
Gradient style clipping expands a vector already under the norm bound.
Case contract
Return v scaled by min(1, bound/L2(v)); zero vectors stay zero and bound is positive.
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 |
|---|---|---|---|
| inside bound | [8.0, 0.0] | [4, 0] | Failed |
