task_illustrations__park_playground__jigsaw_arrangement_label

Summary

• Domain: illustrations
• Scene id: park_playground
• Implementation source scene: park_playground
• Implementation source: src/trace_tasks/tasks/illustrations/park_playground/jigsaw_arrangement_label.py

Task Contract

Renders a park/playground source illustration, cuts it into a profile-aware tile grid, and shows four lettered complete arrangements of those tiles. Exactly one option preserves the original row-major tile order. The model selects the option letter for the correct arrangement.

Program Contract

Program: select_option(match_jigsaw_arrangement(tile_set, arrangement_options, correct_order=row_major)); scene=park_playground; scope=jigsaw_arrangement_label

Candidate set: the visible illustrated scene objects, people, regions, tiles, patches, labels, and option panels inside the jigsaw_arrangement_label objective scope. Operands: visible scene state and prompt-bound operands named by match_jigsaw_arrangement, tile_set, arrangement_options, correct_order, row_major, park_playground, jigsaw_arrangement_label. Operation: evaluate select_option over the candidate set using the visible illustrated objects, regions, layout relationships, counts, patch/tile transforms, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the option_letter schema; one of the visible option letters A through D. Annotation witnesses: annotation uses the bbox schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

Program Metadata

• Program signatures: selection.option_match
• Base program contract: select_option(match_jigsaw_arrangement(tile_set, arrangement_options, correct_order=row_major)); scene=park_playground; scope=jigsaw_arrangement_label
• Parameter axes: person_count, equipment_count, source_size, canvas_profile
• Arguments:
• tile_set: semantic_role; allowed profile_aware_park_playground_tiles; source program_schema_concrete
• arrangement_options: semantic_role; allowed A_D_lettered_tile_arrangements; source program_schema_concrete
• correct_order: operation_parameter; allowed row_major; source program_schema_concrete
• Argument metadata status: curated
• Supported query ids: single

Answer Contract

• Answer schema: option_letter
• Generator answer_gt.type: option_letter
• The answer value is one of the visible option letters A through D.

Annotation Contract

• Annotation schema: bbox
• Generator annotation_gt.type: bbox
• Annotation contains exactly one bbox: the final-image pixel box around the selected jigsaw arrangement option image.
• Do not include the option label badge, all options, source-scene objects, or context-only regions.

Prompt And Trace Requirements

• Prompt text must come from src/trace_tasks/resources/prompts/illustrations/park_playground/illustrations_park_playground_v0.json.
• Render randomness, sampled park setting/style, source scene counts, option-label font, option permutations, selected option, and verifier payloads must be explicit in the instance trace.
• Source panels are accepted only when every source tile has enough visual detail to avoid flat-background jigsaw options.
• The selected option bbox, answer label, option permutations, and source tile boxes must all come from the same compose_jigsaw_arrangement_options execution trace.
