task_charts__part_whole__contiguous_chart_order_sum

Contract

1. Domain: charts
2. Scene id: part_whole
3. Supported query_id: clockwise_span, counterclockwise_span
4. Answer schema: integer_value
5. Annotation schema: point_map

Implementation

1. Registered class: trace_tasks.tasks.charts.part_whole.contiguous_chart_order_sum.ChartsCompositionChartContiguousOrderSumTask
2. Prompt lookup domain/scene: charts/part_whole
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: sum(value(category) for category in contiguous_circular_span(start_category, end_category, direction)); scene=part_whole; scope=contiguous_chart_order_sum

Candidate set: the visible part-whole segments, slices, and category labels inside the contiguous_chart_order_sum 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 sum 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 unspecified value bound by unspecified. Annotation witnesses: unspecified witnesses bound by see_annotation_contract. The Annotation Contract below defines the prompt-facing witnesses. Query ids: clockwise_span, counterclockwise_span.

Reasoning Operations

Families: aggregation, topology

Annotation Contract

Annotation maps each included category label to the [x,y] pixel point at the center of its chart segment.
