task_charts__area__stacked_band_dominance_label

Contract

1. Domain: charts
2. Scene id: area
3. Source scene: charts/area
4. Query id: single
5. Semantic query details are recorded in trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.area.stacked_band_dominance_label.ChartsAreaStackedDominanceLabelTask
2. Prompt lookup scene: charts/area
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 should mark the minimal visual witnesses required by the task, following the cross-domain annotation policy.
4. Renderer context such as legends, axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation.

Program Contract

Program: argmax(category_label, sum(value(category_label,x) for x in selected_x_interval)); output=string_label; annotation=point_set(winning_category_interval_marks); scene=area; scope=stacked_band_dominance_label

Candidate set: the visible area-series bands, category labels, and interval endpoints inside the stacked_band_dominance_label objective scope. Operands: prompt-bound labels, categories, series names, thresholds, intervals, references, and encoded chart values, plus the task's prompt-bound target operands when present. Operation: evaluate argmax 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(winning_category_interval_marks). Annotation should mark the minimal visual witnesses required by the task, following the cross-domain annotation policy. Renderer context such as legends, axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation. Query ids: single.
