FA-100317 / Dataset deduplication grouping / Member archive
Dataset deduplication: signature selects maximum hash per band · case 02
signature selects maximum hash per band.
Case contract
Return the componentwise minimum of nonempty equal-width integer signatures; empty input returns [].
Why this case matters
This deterministic toy operation makes one dataset equivalence or representative rule explicit.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| component minima | [4, 5] | [2, 2] | Failed |
