Fair share computed against full-time headcount · case 05

Targets sum to less than the duties when staff are part-time.

Member previewVariant 5 · 3 implementations · 8 checks per implementation

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.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: fte denominator 1	`[[["st0", 3, 1], ["st1", 5, 2], ["st2", 1, 3], ["st3", 3, 4], ["st4", 3, -3]], ["st1", "st2", "st3", "st4"]]`	`[[["st0", 4, 0], ["st1", 9, -2], ["st2", 2, 2], ["st3", 5, 2], ["st4", 4, -4]], ["st1", "st2", "st3", "st4"]]`	Failed
