task_charts__single_series__threshold_value_count

Contract

1. Domain: charts
2. Scene id: single_series
3. Source implementation: src/trace_tasks/tasks/charts/single_series/threshold_value_count.py
4. Public task id: task_charts__single_series__threshold_value_count
5. Supported query_id values: above_threshold_count, below_threshold_count
6. Query ids are internal replay metadata; scene style, label pool, mark count, and context mode are generation metadata.

Implementation

1. Registered class: trace_tasks.tasks.charts.single_series.threshold_value_count.ChartsCountingThresholdValueCountTask
2. Prompt lookup: src/trace_tasks/resources/prompts/charts/single_series/charts_counting_v1.json
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.

Program Contract

Program: count(filter(marks, value(mark) comparison threshold)); output=integer_count; annotation=point_set(matching_marks); scene=single_series; scope=threshold_value_count

Candidate set: the visible marks in the ordered single-series chart inside the threshold_value_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(matching_marks). Annotation marks every visible mark satisfying the strict threshold predicate. Axes, legend, titles, captions, decorative context, and distractor text are context unless the task explicitly asks for them as annotation. Query ids: above_threshold_count, below_threshold_count.

Reasoning Operations

Families: filtering, counting, comparison

Annotation Contract

1. Answer schema: integer_count.
2. Annotation schema: point_set.
3. Annotation marks every visible mark satisfying the strict threshold predicate.
4. Axes, legend, titles, captions, decorative context, and distractor text are context unless the task explicitly asks for them as annotation.
