task_charts__treemap__parent_total_extremum_label

Public Contract

1. Domain: charts
2. Scene: treemap
3. Source file: src/trace_tasks/tasks/charts/treemap/parent_total_extremum_label.py
4. Prompt assets: src/trace_tasks/resources/prompts/charts/treemap/charts_treemap_v1.json
5. Supported query_id values: largest_parent_total, smallest_parent_total

Program Contract

Program: select(parent where sum(value(child) for child in parent) is extremum(direction)); direction={largest,smallest}; output=string_label; annotation=bbox_set(parent_child_rectangles); scene=treemap; scope=parent_total_extremum_label

Candidate set: the visible treemap rectangles and hierarchy labels inside the parent_total_extremum_label 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 select 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 string_label. Annotation witnesses: unspecified witnesses bound by bbox_set(parent_child_rectangles). The Annotation Contract below defines the prompt-facing witnesses. Query ids: largest_parent_total, smallest_parent_total.

Reasoning Operations

Families: ranking, aggregation, topology

Contract Notes

This task uses the current source layout. Query ids select the extremum direction; public task code owns the parent-total comparison, answer binding, annotation leaf ids, prompt slots, and task-specific trace fields.
