task_charts__sunburst__parent_total_extremum_label

Contract

1. Domain: charts
2. Scene id: sunburst
3. Public task id: task_charts__sunburst__parent_total_extremum_label
4. Supported query_id: highest_parent_total_label, lowest_parent_total_label

Implementation

1. Registered class: trace_tasks.tasks.charts.sunburst.parent_total_extremum_label.ChartsSunburstParentTotalExtremumLabelTask
2. Prompt bundle: charts_sunburst_v1
3. Generation is deterministic from instance_seed, explicit params, prompt bundle, renderer config, and code versions.
4. Answers and annotation are produced from the same metadata execution trace.

Annotation Contract

1. Answer schema: string_label.
2. Annotation schema: point_set.
3. Annotation marks the centers of the printed outer leaf value labels under the answer parent category.
4. Renderer context such as decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation.

Program Contract

Program: arg_extremum(parent, sum(value(leaf) for leaf under parent), direction={highest,lowest}); output=string_label; annotation=point_set(answer_parent_leaf_value_labels); scene=sunburst; scope=parent_total_extremum_label

Candidate set: the visible hierarchy wedges, rings, and node labels inside the parent_total_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 arg_extremum 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: point_set witnesses bound by point_set(answer_parent_leaf_value_labels). Annotation marks the centers of the printed outer leaf value labels under the answer parent category. Renderer context such as decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation. Query ids: highest_parent_total_label, lowest_parent_total_label.

Reasoning Operations

Families: ranking, aggregation, topology
