Weighted pooling divides by token count · case 05
Weighted pooling divides by token count.
Case contract
Pool equal-width vectors with nonnegative weights into a weighted mean; total weight zero or no vectors returns empty.
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 | [15, 35] | [3.75, 8.75] | Failed |
