Two objective buckets share one normalization denominator · case 04
Two objective buckets share one normalization denominator.
Case contract
Each bucket is a separate objective with its own sums and counts. Return its total sum divided by its total count, with zero for an empty bucket.
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 |
|---|---|---|---|
| independent objectives | [1.75, 1.25] | [3.5, 2.5] | Failed |
