task_charts__scientific_axis_frame__axis_span_value

Contract

1. Domain: charts
2. Scene id: scientific_axis_frame
3. Source implementation domain/scene: charts/scientific_axis_frame
4. Supported query_id values: x_axis_span_value, y_axis_span_value
5. Semantic query details are recorded in query_id and trace params.

Program Contract

Program: difference(max_visible_tick(axis), min_visible_tick(axis)); output=integer_value; annotation=segment(axis_visible_span); scene=scientific_axis_frame; scope=axis_span_value

Candidate set: the visible scientific-axis ticks, marked points, and scale labels inside the axis_span_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 difference 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: segment witnesses bound by segment(axis_visible_span). Annotation is the segment from the smallest visible tick mark to the largest visible tick mark on the requested axis. Decorative plotted data, axis labels, and distractor text are metadata unless explicitly queried. Annotation marks the visible span on the requested axis as one segment between the minimum and maximum tick marks. Query ids: x_axis_span_value, y_axis_span_value.

Reasoning Operations

Families: formula_evaluation

Implementation

1. Registered class: trace_tasks.tasks.charts.scientific_axis_frame.axis_span_value.ChartsScientificAxisFrameAxisSpanValueTask
2. Prompt lookup domain/scene: charts/scientific_axis_frame
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: segment.
3. Annotation is the segment from the smallest visible tick mark to the largest visible tick mark on the requested axis.
4. Decorative plotted data, axis labels, and distractor text are metadata unless explicitly queried.
5. Annotation marks the visible span on the requested axis as one segment between the minimum and maximum tick marks.
