Contract

1. Domain: games
2. Scene: space_shooter
3. Scene id: space_shooter
4. Public task id: task_games__space_shooter__hit_enemy_ship_label
5. Supported query_id values: single
6. Answer schema: option_letter
7. Annotation schema: bbox

Program Contract

Program: select(label in visible_candidate_enemy_ships where enemy_ship_id in lower_first_hits_by_lane(blue_player_shots, enemy_ships)); scene=space_shooter; scope=hit_enemy_ship_label

Candidate set: the visible game board, pieces, tokens, cards, tiles, marked state, legal-move cues, result panels, and labeled options inside the hit_enemy_ship_label objective scope. Operands: visible scene state and prompt-bound operands named by label, visible_candidate_enemy_ships, where, enemy_ship_id, lower_first_hits_by_lane, blue_player_shots, enemy_ships, space_shooter, hit_enemy_ship_label. Operation: evaluate select 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 option_letter 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: ranking, spatial_relations, state_update

Generation Notes

1. single is the only public query id; the task-specific prompt key is trace metadata.
2. Exactly four candidate enemy ships are visibly labeled A through D.
3. Blue player shots move upward in their lane; each visible blue shot can destroy one enemy ship above it in that same lane.
4. If a lane has fewer blue shots than enemy ships, the lower enemy ships are destroyed first.
5. Exactly one labeled candidate ship is hit under that rule; unlabeled ships may also be hit.
6. Annotation is the scalar bbox of the selected labeled enemy ship.
7. Scalar annotation checked: true.
