Preference pairs: disagreeing annotations are collapsed to a winner · case 02
disagreeing annotations are collapsed to a winner.
Case contract
Rows are [chosen,rejected] votes for one pair. Return that orientation only if every vote agrees; empty or conflicting votes return None.
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 |
|---|---|---|---|
| split vote | ["a2", "b2"] | null | Failed |
