Under-assigned staff never flagged · case 05

Staff carrying far fewer duties than their share pass the report.

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.

Boundary fixture	Actual	Expected	Outcome
regression: deviation flag 1	`[[["st0", 1, 9], ["st1", 2, 2], ["st2", 2, -2], ["st3", 0, 0], ["st4", 2, 1]], ["st0", "st1"]]`	`[[["st0", 1, 9], ["st1", 2, 2], ["st2", 2, -2], ["st3", 0, 0], ["st4", 2, 1]], ["st0", "st1", "st2"]]`	Failed
