task_charts__error_interval__reference_containment_count

Contract

1. Domain: charts
2. Scene id: error_interval
3. Source implementation domain/group: charts/error_interval
4. Query id: single
5. Semantic query details are recorded in query_id and trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.error_interval.reference_containment_count.ChartsErrorIntervalReferenceContainmentCountTask
2. Prompt lookup domain/group: charts/error_interval
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_count.
2. Annotation schema: segment_set.
3. Annotation marks each matching interval's lower-to-upper visual span as one segment, following the cross-domain annotation policy.
4. Renderer context such as legends, axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation.

Program Contract

Program: count(filter(intervals, lower <= reference_value <= upper)); output=integer_count; annotation=segment_set(matching_interval_lower_upper_spans); scene=error_interval; scope=reference_containment_count

Candidate set: the visible interval marks, reference lines, and category labels inside the reference_containment_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 integer_count value bound by integer_count. Annotation witnesses: segment_set witnesses bound by segment_set(matching_interval_lower_upper_spans). Annotation marks each matching interval's lower-to-upper visual span as one segment, following the cross-domain annotation policy. Renderer context such as legends, axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation. Query ids: single.
