task_charts__style_legend__threshold_series_count

Contract

1. Domain: charts
2. Scene id: style_legend
3. Public task id: task_charts__style_legend__threshold_series_count
4. Supported query_id: above_threshold_series_count, below_threshold_series_count

Implementation

1. Registered class: trace_tasks.tasks.charts.style_legend.threshold_series_count.ChartsStyleLegendThresholdSeriesCountTask
2. Prompt bundle: charts_style_legend_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: integer_count.
2. Annotation schema: point_set.
3. Annotation marks each counted plotted marker at the queried x-axis label; use an empty array when the count is zero.
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(filter(series, compare(value(series, x_position), threshold, comparator={above,below}))); output=integer_count; annotation=point_set; scene=style_legend; scope=threshold_series_count

Candidate set: the visible plotted series/marks and legend entries inside the threshold_series_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. Annotation marks each counted plotted marker at the queried x-axis label; use an empty array when the count is zero. 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: above_threshold_series_count, below_threshold_series_count.

Reasoning Operations
