task_charts__curve_panels__panel_curve_threshold_crossing_count

Contract

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

Implementation

1. Registered class: trace_tasks.tasks.charts.curve_panels.panel_curve_threshold_crossing_count.ChartsScientificPanelCurveThresholdCrossingCountTask
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: integer_count.
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: count(curve_label in panel_label where crosses_threshold(curve_label, threshold, direction={upward,downward})); output=integer_count; annotation=point_set(threshold_crossing_marks); scene=curve_panels; scope=panel_curve_threshold_crossing_count

Candidate set: the visible curve panels, curve traces, points, and panel labels inside the panel_curve_threshold_crossing_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: point_set witnesses bound by point_set(threshold_crossing_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: panel_curve_upward_threshold_crossing_count, panel_curve_downward_threshold_crossing_count.
