task_charts__uncertainty_band__band_overlap_count

Public Contract

1. Domain: charts
2. Scene: uncertainty_band
3. Source file: src/trace_tasks/tasks/charts/uncertainty_band/band_overlap_count.py
4. Prompt assets: src/trace_tasks/resources/prompts/charts/uncertainty_band/charts_uncertainty_band_v1.json
5. Supported sampled query_id: single

Program Contract

Program: count(x_label where intersects(vertical_interval(series_a_band_at_x), vertical_interval(series_b_band_at_x))); output=integer_value; annotation=point_set(overlap_region_centers); scene=uncertainty_band; scope=band_overlap_count

Candidate set: the visible uncertainty bands, central series marks, and x labels inside the band_overlap_count 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 count 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 point_set(overlap_region_centers). The Annotation Contract below defines the prompt-facing witnesses. Query ids: single.

Reasoning Operations

Families: filtering, counting, spatial_relations

Contract Notes

This task uses the current source layout. The public task file owns overlap construction, answer binding, annotation binding, query metadata, and prompt slots; scene-local shared code only provides uncertainty-band data structures, rendering, prompt, and projection primitives.
