task_games__2048__move_result_board_label

Contract

1. Domain: games
2. Scene package: src/trace_tasks/tasks/games/2048/
3. Scene id: 2048
4. Public task id: task_games__2048__move_result_board_label
5. Supported query_id values: single
6. Prompt query key: move_result_board_label
7. Answer schema: string_label
8. Annotation schema: bbox
9. Program schema: label(select_option(candidate_result_boards, option_board = simulate(board, rules=slide_merge_2048, action=move_direction).final_board)); scene=2048; scope=move_result_board_label

Program Contract

Program: label(select_option(candidate_result_boards, option_board = simulate(board, rules=slide_merge_2048, action=move_direction).final_board)); scene=2048; scope=move_result_board_label

Candidate set: the visible game board, pieces, tokens, cards, tiles, marked state, legal-move cues, result panels, and labeled options inside the move_result_board_label objective scope. Operands: visible scene state and prompt-bound operands named by select_option, candidate_result_boards, option_board, simulate, board, rules, slide_merge_2048, action, move_direction, final_board, move_result_board_label. Operation: evaluate label over the candidate set using the visible game state, rules, legal moves, comparisons, counts, simulations, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the string schema; generation binds a unique final answer. Annotation witnesses: annotation uses the bbox schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

Reasoning Operations

Families: state_update

Generation Notes

1. Query ids are internal replay/sampling keys and do not define public task units.
2. Annotation is the scalar bounding box around the single selected candidate board.
3. Annotation is projected from the same generated game state used for answer verification.
