ScratchWorld - Debug: leaderboard

Debug tasks from ScratchWorld (Zhang et al., 2026): find and repair the logical errors in a broken Scratch project so that it behaves as specified, checked by unit tests run in the Scratch VM. Composite mode, where the agent reads the program as pseudocode and edits it through semantic commands such as adding or connecting blocks instead of the GUI. The score is the percentage of the 20 tasks on which every unit test passes; higher is better.
