Program Contract

1. Program schema: numeric.ranked_difference(candidate_sets=all_sections, aggregate=sum_printed_values, selected_sections=highest_total|lowest_total); scene=infographic; scope=one multi-section metric-card infographic
2. Contract: total every section, identify the unique highest-total and lowest-total sections, then return highest total minus lowest total.
3. Public query id: single
4. Answer schema: integer
5. Annotation schema: bbox_set_map with keys highest_total_section and lowest_total_section, each containing that section's metric-card boxes.
6. Query argument axes: section totals derived from visible card values.
7. scalar_annotation_checked=true

Prompt + Trace

1. Prompt bundle: pages_infographic_v1
2. Scene key: infographic_metric_arithmetic
3. Task key: metric_arithmetic_query
4. Prompt query key: section_total_extrema_difference
5. Trace records every section total, selected high/low sections, answer expression, and supporting card boxes. Public annotation preserves the high/low section grouping while leaving label-keyed card boxes in trace diagnostics.
