task_charts__histogram__cumulative_rank_bin_label

Contract

1. Domain: charts
2. Scene id: histogram
3. Source implementation scene: charts/histogram
4. Query id: single
5. Semantic query details are recorded in trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.histogram.cumulative_rank_bin_label.ChartsDistributionHistogramCumulativeRankLabelTask
2. Prompt lookup domain/scene: charts/histogram
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_value.
2. Annotation schema: bbox.
3. Annotation marks the single histogram bar containing the requested cumulative item rank.
4. Renderer context such as axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation.

Program Contract

Program: label(bin containing cumulative_rank(target_rank, counts_left_to_right)); output=integer_value; annotation=bbox(answer_bin); scene=histogram; scope=cumulative_rank_bin_label

Candidate set: the visible histogram bins and axis/value labels inside the cumulative_rank_bin_label 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 label 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: bbox witnesses bound by bbox(answer_bin). Annotation marks the single histogram bar containing the requested cumulative item rank. Renderer context such as axes, decorative labels, titles, and distractor text is metadata unless the task explicitly asks for it as annotation. Query ids: single.

Reasoning Operations

Families: ranking, aggregation
