Mean-reduced microbatch losses are summed · case 04
Mean-reduced microbatch losses are summed.
Case contract
Each input is one sum-reduced microbatch contribution. Return the total without dividing by a count.
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 |
|---|---|---|---|
| two sums | 12.0 | 24 | Failed |
