FA-100082 / Preference pair construction / Member archive
Preference pairs: weights are normalized across unrelated prompts · case 02
weights are normalized across unrelated prompts.
Case contract
Rows are [prompt,id,weight]. Return [prompt,id,numerator,denominator] for positive weights normalized by prompt sum, preserving input order.
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 |
|---|---|---|---|
| separate denominators | [["p2", "a", 2, 8], ["p2", "b", 2, 8], ["q2", "c", 4, 8]] | [["p2", "a", 1, 2], ["p2", "b", 1, 2], ["q2", "c", 1, 1]] | Failed |
