task_charts__single_series__remaining_mean_after_removal

Contract

1. Domain: charts
2. Scene id: single_series
3. Source implementation: src/trace_tasks/tasks/charts/single_series/remaining_mean_after_removal.py
4. Public task id: task_charts__single_series__remaining_mean_after_removal
5. Supported query_id values: single
6. Query ids are internal replay metadata; scene style, label pool, mark count, and context mode are generation metadata.

Implementation

1. Registered class: trace_tasks.tasks.charts.single_series.remaining_mean_after_removal.ChartsHypotheticalRemainingMeanAfterRemovalPublicTask
2. Prompt lookup: src/trace_tasks/resources/prompts/charts/single_series/charts_hypothetical_v1.json
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.

Program Contract

Program: mean(values(marks excluding removed_labels)); output=integer_value; annotation=point_set(retained_marks); scene=single_series; scope=remaining_mean_after_removal

Candidate set: the visible marks in the ordered single-series chart inside the remaining_mean_after_removal 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 mean 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: point_set witnesses bound by point_set(retained_marks). Annotation marks every retained visible mark used in the remaining mean. Axes, legend, titles, captions, decorative context, and distractor text are context unless the task explicitly asks for them as annotation. Query ids: single.

Reasoning Operations

Families: aggregation, state_update

Annotation Contract

1. Answer schema: integer_value.
2. Annotation schema: point_set.
3. Annotation marks every retained visible mark used in the remaining mean.
4. Axes, legend, titles, captions, decorative context, and distractor text are context unless the task explicitly asks for them as annotation.
