FA-100074 / Preference pair construction / Member archive
Preference pairs: sub-threshold rating gaps are accepted · case 04
sub-threshold rating gaps are accepted.
Case contract
Rows are [chosen,rejected,chosen_score,rejected_score]. Return endpoints only when the gap is at least margin.
Why this case matters
A small deterministic preference-data transform makes pair semantics inspectable without a training framework.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| below margin | [["a", "b"]] | [] | Failed |
