Contract

1. Domain: games
2. Scene: tetris

5. Supported query_id values: single
6. Answer schema: string_label

Program Contract

Program: label(option where option.shape_name = shape_label(active_falling_tetromino)); scene=tetris; scope=active_piece_shape_label

Candidate set: the visible game board, pieces, tokens, cards, tiles, marked state, legal-move cues, result panels, and labeled options inside the active_piece_shape_label objective scope. Operands: visible scene state and prompt-bound operands named by where, shape_name, shape_label, active_falling_tetromino, tetris, active_piece_shape_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: matching

Generation Notes

1. The renderer shows a Tetris board with one active falling piece and four text options naming tetromino shapes.
2. The answer is the selected option letter whose shape name matches the falling piece.
3. Annotation is the scalar bbox enclosing the falling-piece cells on the board.
4. Scalar annotation checked: true.
