task_charts__dashboard__panel_value_range_extremum_label

Contract

1. Domain: charts
2. Scene id: dashboard
3. Source implementation domain/group: charts/dashboard
4. Query ids: largest_panel_value_range_label, smallest_panel_value_range_label
5. Semantic query details are recorded in trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.dashboard.panel_value_range_extremum_label.ChartsDashboardPanelValueRangeExtremumLabelTask
2. Prompt lookup domain/group: charts/dashboard
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_map.
3. Annotation keys are largest_value and smallest_value, each pointing to the category mark that defines the answer panel's range.
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: arg_extreme(panel, difference(max(value(category,panel)), min(value(category,panel))), direction={largest,smallest}); output=string_label; annotation=point_map(largest_value, smallest_value); scene=dashboard; scope=panel_value_range_extremum_label

Candidate set: the visible dashboard panels, linked marks, and panel labels inside the panel_value_range_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_extreme 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_map witnesses bound by point_map(largest_value, smallest_value). Annotation keys are largest_value and smallest_value, each pointing to the category mark that defines the answer panel's range. 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: largest_panel_value_range_label, smallest_panel_value_range_label.
