task_charts__combo_mark__dual_threshold_condition_count

Contract

1. Domain: charts
2. Scene id: combo_mark
3. Source implementation domain/scene: charts/combo_mark
4. Query ids: primary_above_and_line_above, primary_above_and_line_below, primary_below_and_line_above
5. Semantic query details are recorded in query_id and trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.combo_mark.dual_threshold_condition_count.ChartsComboDualThresholdConditionCountTask
2. Prompt lookup domain/scene: charts/combo_mark
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: segment_set.
3. Annotation is a segment_set; each segment is two [x, y] pixel points formatted [[x0, y0], [x1, y1]] and connects the primary-series mark point to the overlaid line mark point for one matching category.
4. Annotation should mark the minimal visual witnesses required by the task, following the cross-domain annotation policy.
5. 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(x_label where compare(value(primary,x_label), primary_threshold, primary_relation) and compare(value(line,x_label), line_threshold, line_relation)); output=integer_count; annotation=segment_set(matching_primary_line_marks); scene=combo_mark; scope=dual_threshold_condition_count

Candidate set: the visible primary marks, secondary-line marks, and shared category labels inside the dual_threshold_condition_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: segment_set witnesses bound by segment_set(matching_primary_line_marks). Annotation is a segment_set; each segment is two [x, y] pixel points formatted [[x0, y0], [x1, y1]] and connects the primary-series mark point to the overlaid line mark point for one matching category. 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: primary_above_and_line_above, primary_above_and_line_below, primary_below_and_line_above.
