task_charts__part_whole__adjacent_transfer_gap_value

Contract

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

Implementation

1. Registered class: trace_tasks.tasks.charts.part_whole.adjacent_transfer_gap_value.ChartsCompositionChartAdjacentTransferGapValueTask
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: absolute_difference(value(source_category) - transfer_delta, value(adjacent_category(source_category, direction)) + transfer_delta); scene=part_whole; scope=adjacent_transfer_gap_value

Candidate set: the visible part-whole segments, slices, and category labels inside the adjacent_transfer_gap_value 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 absolute_difference 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_adjacent_transfer, counterclockwise_adjacent_transfer.

Reasoning Operations

Families: spatial_relations, state_update, formula_evaluation

Annotation Contract

Annotation maps the source category label and adjacent target category label to [x,y] pixel points at the centers of their chart segments.
