task_charts__composition_panels__composition_shift_l1_distance

Contract

1. Domain: charts
2. Scene id: composition_panels
3. Public task id: task_charts__composition_panels__composition_shift_l1_distance
4. Query id: single

Implementation

1. Registered class: trace_tasks.tasks.charts.composition_panels.composition_shift_l1_distance.ChartsCompositionPanelsCompositionShiftL1DistanceTask
2. Prompt bundle: charts_composition_panels_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_value.
2. Annotation schema: bbox_set.
3. Annotation marks the two full compared panel boxes.

Program Contract

Program: sum(abs(share(end_panel,segment)-share(start_panel,segment)) for segment in segments); output=integer_value; annotation=bbox_set(compared_panels); scene=composition_panels; scope=composition_shift_l1_distance

Candidate set: the visible panel segments and panel/category labels inside the composition_shift_l1_distance objective scope. Operands: prompt-bound labels, categories, series names, thresholds, intervals, references, and encoded chart values, plus the task's prompt-bound target operands 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 integer_value value bound by integer_value. Annotation witnesses: bbox_set witnesses bound by bbox_set(compared_panels). Annotation marks the two full compared panel boxes. Query ids: single.

Reasoning Operations

Families: aggregation, formula_evaluation
