task_charts__population_pyramid__dominant_side_count

Contract

1. Domain: charts
2. Scene id: population_pyramid
3. Public task id: task_charts__population_pyramid__dominant_side_count
4. Query ids: left_side_greater_count, right_side_greater_count

Implementation

1. Registered class: trace_tasks.tasks.charts.population_pyramid.dominant_side_count.ChartsPopulationPyramidDominantSideCountTask
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: integer_count.
2. Annotation schema: bbox_set.
3. Annotation marks one row bbox around the paired bars for each row where the queried side is greater than the other side.

Program Contract

Program: count(filter(age_group_rows, value(row, side) > value(row, other_side))); output=integer_count; annotation=bbox_set(counted_age_group_rows); scene=population_pyramid; scope=dominant_side_count

Candidate set: the visible left/right population bars and age-group labels inside the dominant_side_count 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 count 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 integer_count value bound by integer_count. Annotation witnesses: bbox_set witnesses bound by bbox_set(counted_age_group_rows). Annotation marks one row bbox around the paired bars for each row where the queried side is greater than the other side. Query ids: left_side_greater_count, right_side_greater_count.
