task_charts__curve_panels__endpoint_rank_panel_label

Contract

1. Domain: charts
2. Scene id: curve_panels
3. Source implementation domain/group: charts/curve_panels
4. Query ids: start_highest_panel_label, start_lowest_panel_label, end_highest_panel_label, end_lowest_panel_label
5. Semantic query details are recorded in query_id and trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.curve_panels.endpoint_rank_panel_label.ChartsScientificEndpointRankPanelLabelTask
2. Prompt lookup domain/group: charts/curve_panels
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.
3. Annotation should mark the selected endpoint marker in the answer subplot.
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_label, value(method,endpoint={start,end},panel_label), direction={highest,lowest}); output=string_label; annotation=point(answer_endpoint_mark); scene=curve_panels; scope=endpoint_rank_panel_label

Candidate set: the visible curve panels, curve traces, points, and panel labels inside the endpoint_rank_panel_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 witnesses bound by point(answer_endpoint_mark). Annotation should mark the selected endpoint marker in the answer subplot. 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: start_highest_panel_label, start_lowest_panel_label, end_highest_panel_label, end_lowest_panel_label.
