task_charts__candlestick__range_extremum_label

Contract

1. Domain: charts
2. Scene id: candlestick
3. Source implementation scene: charts/candlestick
4. Query ids: largest_wick_range_label, smallest_wick_range_label, largest_body_range_label, smallest_body_range_label
5. Semantic query details are recorded in query_id and trace params.

Implementation

1. Registered class: trace_tasks.tasks.charts.candlestick.range_extremum_label.ChartsCandlestickRangeExtremumLabelTask
2. Prompt lookup domain/scene: charts/candlestick
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: string_label.
2. Annotation schema: segment.
3. Annotation should mark the minimal visual witnesses required by the task, 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: arg_extreme(candle_label, range(candle_label, range_kind={wick,body}), direction={largest,smallest}); output=string_label; annotation=segment(answer_candle_range_mark); scene=candlestick; scope=range_extremum_label

Candidate set: the visible candlestick glyphs and period/category labels inside the range_extremum_label 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 arg_extreme 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 string_label value bound by string_label. Annotation witnesses: segment witnesses bound by segment(answer_candle_range_mark). Annotation should mark the minimal visual witnesses required by the task, 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: largest_wick_range_label, smallest_wick_range_label, largest_body_range_label, smallest_body_range_label.
