Long sequences dominate a sequence-mean objective · case 05
Long sequences dominate a sequence-mean objective.
Case contract
Compute each nonempty sequence mean and then average sequences equally; sequences with zero tokens are skipped.
Why this case matters
A deterministic toy model isolates one local accumulation contract.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| different lengths | 3.5 | 3 | Failed |
