task_charts__waterfall__remove_step_final_total

Contract

1. Domain: charts
2. Scene id: waterfall
3. Source implementation: src/trace_tasks/tasks/charts/waterfall/remove_step_final_total.py
4. Public query id: single
5. Prompt query key: remove_step_final_total

Implementation

1. Registered class: trace_tasks.tasks.charts.waterfall.remove_step_final_total.ChartsWaterfallRemoveStepFinalTotalTask
2. Prompt bundle: src/trace_tasks/resources/prompts/charts/waterfall/charts_waterfall_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.

Annotation Contract

1. Answer schema: integer_value.
2. Annotation schema: bbox_map.
3. final_total_bar marks the full final-total bar.
4. target_contribution_bar marks the full contribution bar being removed.

Program Contract

Program: final_total - delta(target_step); target_step=visible_step_label; output=integer_value; annotation=bbox_map(final_total_bar,target_contribution_bar); scene=waterfall; scope=remove_step_final_total

Candidate set: the visible waterfall bars, contribution steps, and total bars inside the remove_step_final_total 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 final_total - delta 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_map witnesses bound by bbox_map(final_total_bar,target_contribution_bar). final_total_bar marks the full final-total bar. target_contribution_bar marks the full contribution bar being removed. Query ids: single.

Reasoning Operations

Families: aggregation, state_update, formula_evaluation
