Contract

1. Domain: games
2. Scene id: bingo
3. Public task id: task_games__bingo__completed_column_label
4. Supported query_id values: single
5. Answer schema: string_label
6. Annotation schema: segment
7. Program schema: label(unique_completed_column(board)); scene=bingo; scope=completed_column_label

Program Contract

Program: label(unique_completed_column(board)); scene=bingo; scope=completed_column_label

Candidate set: the visible game board, pieces, tokens, cards, tiles, marked state, legal-move cues, result panels, and labeled options inside the completed_column_label objective scope. Operands: visible scene state and prompt-bound operands named by unique_completed_column, board, bingo, completed_column_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 segment schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

Reasoning Operations

Families: filtering

Generation Notes

1. The card has exactly one completed BINGO column.
2. The answer is one of B, I, N, G, or O.
3. Annotation is one segment [[x0, y0], [x1, y1]] connecting the top and bottom cell centers of the completed column.
