Program Contract

Program: abs(sum(values(row_a, years)) - sum(values(row_b, years))); output=integer_value; annotation=bbox_map(row_interval_span_by_row_label); scene=table; scope=absolute_difference_between_rows_over_year_interval

Candidate set: the visible table cells with row and column labels inside the absolute_difference_between_rows_over_year_interval 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 abs 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 integer_value. Annotation witnesses: unspecified witnesses bound by bbox_map(row_interval_span_by_row_label). The Annotation Contract below defines the prompt-facing witnesses. Query ids: single.

Reasoning Operations

Families: aggregation, formula_evaluation

Contract Notes

This task uses the current source layout. Scene-local reusable code lives under src/trace_tasks/tasks/charts/table/shared/; public task files own objective logic, query selection, answer binding, and annotation binding.
