Case contract

staff [name, FTE percent, duties assigned] and total duties. Each target is total * FTE / sum of FTE rounded half up. Deviation = assigned - target; flag staff whose absolute deviation exceeds one. Return [[name, target, deviation], flagged names].

Why this case matters

Invigilation duties are distributed pro rata to contracted hours; fairness reports drive reallocation.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

regression: target rounding 1	`[[["a", 3, 0], ["b", 3, -1]], []]`	`[[["a", 4, -1], ["b", 4, -2]], ["b"]]`	Failed
