Case contract

Apply lineup swaps [time, slot, incoming player] in time order (submission order on equal times). A swap is rejected if either the outgoing or incoming player's game has kicked off at or before the swap time, or if the incoming player already occupies another slot. Return the final lineup, the sorted indices of rejected swaps and the lineup's total points.

Why this case matters

Game-time lineup locks decide whether late swaps count; wrong lock semantics let users bench players after they score.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: kickoff instant lock	`{"final": {"S1": "p0", "S2": "p1", "S3": "p6"}, "rejected": [0], "total": 48}`	`{"final": {"S1": "p0", "S2": "p1", "S3": "p2"}, "rejected": [0, 1], "total": 27}`	Failed
