task_charts__sankey__node_side_total_value

Contract

1. Domain: charts
2. Scene id: sankey
3. Task id: task_charts__sankey__node_side_total_value
4. Objective contract: node_side_total_value
5. Supported query_id values: source_outgoing_total_flow, target_incoming_total_flow

Program Contract

Program: sum(value(link) for link in node_side_links(node, side)); scene=sankey; scope=node_side_total_value

Candidate set: the visible flow nodes, links, and labels inside the node_side_total_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 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: point_set witnesses bound by see_annotation_contract. Annotation marks multiple printed value-label centers: every outgoing or incoming band included in the node-side total contributes one point. Node boxes, unselected flow labels, flow curves, title, and panel frame are context unless explicitly referenced by the task. Query ids: source_outgoing_total_flow, target_incoming_total_flow.

Reasoning Operations
