task_illustrations__library__rotated_tile_label

Summary

• Domain: illustrations
• Scene id: library
• Implementation source scene: library
• Implementation source: src/trace_tasks/tasks/illustrations/library/rotated_tile_label.py

Task Contract

Renders a library source illustration as a profile-aware grid of lettered square tiles, with exactly one tile rotated. The model selects the letter of the rotated tile.

Program Contract

Program: select_label(find_rotated_tile(tile_grid, labels=visible_letters)); scene=library; scope=rotated_tile_label

Candidate set: the visible illustrated scene objects, people, regions, tiles, patches, labels, and option panels inside the rotated_tile_label objective scope. Operands: visible scene state and prompt-bound operands named by find_rotated_tile, tile_grid, labels, visible_letters, library, rotated_tile_label. Operation: evaluate select_label 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 tile letters. Annotation witnesses: annotation uses the bbox schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

Program Metadata

• Program signatures: selection.visual_anomaly
• Base program contract: select_label(find_rotated_tile(tile_grid, labels=visible_letters)); scene=library; scope=rotated_tile_label
• Parameter axes: section_count, section_book_counts, rotation_degrees, canvas_profile
• Arguments:
• tile_grid: semantic_role; allowed lettered_library_tile_grid; source program_schema_concrete
• labels: semantic_role; allowed A_F_or_A_I; source program_schema_concrete
• rotation_degrees: render_parameter; allowed 90, 270; source trace_metadata
• canvas_profile: render_parameter; allowed landscape, square, portrait; source trace_metadata
• 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 tile letters.

Annotation Contract

• Annotation schema: bbox
• Generator annotation_gt.type: bbox
• Annotation contains exactly one final-image pixel box around the rotated tile. Do not include all tile options, tile labels, books, shelf sections, or context-only source-scene regions.

Prompt And Trace Requirements

• Prompt text must come from src/trace_tasks/resources/prompts/illustrations/library/illustrations_library_v0.json.
• Render randomness, sampled library setting/style, section/book counts, tile-label font, grid style, selected tile, and verifier payloads must be explicit in the instance trace.
• The selected tile is sampled only from tiles with enough visual detail and rotation difference to make the anomaly visible.
• Quarter-turn rotations require square source cells; the source profile chooses a landscape 2x3, square 3x3, or portrait 3x2 grid.
• The composed grid must be full-bleed over the source image with no decorative outer margin, border, or background frame.
• The selected tile bbox, answer label, and rotated tile index must all come from the same compose_rotated_tile_grid execution trace.
