task_charts__population_pyramid__side_value_extremum_label

Contract

1. Domain: charts
2. Scene id: population_pyramid
3. Public task id: task_charts__population_pyramid__side_value_extremum_label
4. Query ids: left_side_largest_value_label, left_side_smallest_value_label, right_side_largest_value_label, right_side_smallest_value_label

Implementation

1. Registered class: trace_tasks.tasks.charts.population_pyramid.side_value_extremum_label.ChartsPopulationPyramidSideValueExtremumLabelTask
2. Prompt bundle: src/trace_tasks/resources/prompts/charts/population_pyramid/charts_population_pyramid_v1.json
3. Answers and annotation are produced from the same metadata execution trace.

Annotation Contract

1. Answer schema: string_label.
2. Annotation schema: bbox.
3. Annotation marks the selected side-specific bar as one [x0, y0, x1, y1] pixel box.

Program Contract

Program: select_label(arg_extremum(age_group_rows, value(row, side), direction)); output=string_label; annotation=bbox(answer_side_bar); scene=population_pyramid; scope=side_value_extremum_label

Candidate set: the visible left/right population bars and age-group labels inside the side_value_extremum_label objective scope. Operands: prompt-bound labels, categories, series names, thresholds, intervals, references, and encoded chart values, plus the active query id's comparator, direction, target role, or extremum focus when present. Operation: evaluate select_label over the candidate set using the filters, comparisons, aggregations, rankings, projections, or counterfactual edits named in the program expression; generation enforces a unique final answer. Output binding: answer is the string_label value bound by string_label. Annotation witnesses: bbox witnesses bound by bbox(answer_side_bar). Annotation marks the selected side-specific bar as one [x0, y0, x1, y1] pixel box. Query ids: left_side_largest_value_label, left_side_smallest_value_label, right_side_largest_value_label, right_side_smallest_value_label.
