task_illustrations__environment__crossing_feature_count

Summary

  • Domain: illustrations
  • Scene id: environment
  • Implementation scene: environment
  • Implementation source: src/trace_tasks/tasks/illustrations/environment/crossing_feature_count.py

Task Contract

Counts visible features that cross a queried road or river feature.

Program Contract

Program: count(filter(environment_features, crosses(feature, target_linear_feature))); scene=environment; scope=crossing_feature_count

Candidate set: the visible illustrated scene objects, people, regions, tiles, patches, labels, and option panels inside the crossing_feature_count objective scope. Operands: visible scene state and prompt-bound operands named by filter, environment_features, crosses, feature, target_linear_feature, environment, crossing_feature_count. Operation: evaluate count over the candidate set using the visible illustrated objects, regions, layout relationships, counts, patch/tile transforms, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the integer schema; a non-negative integer derived from the same execution trace as the annotation. Annotation witnesses: annotation uses the bbox_set schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

  • Argument metadata status: curated
  • Supported query ids: single

Answer Contract

  • Answer schema: integer_count
  • Generator answer_gt.type: integer
  • The answer value is a non-negative integer derived from the same execution trace as the annotation.

Annotation Contract

  • Annotation schema: bbox_set
  • Generator annotation_gt.type: bbox_set
  • Annotation is an unordered set of final-image pixel points, one near the center of each counted/selected visual witness. Do not include labels, numeric annotations, or context-only regions.
  • Annotation and answer must be projected from the same generated scene trace, not inferred from pixels or prompt text.

Prompt And Trace Requirements

  • Prompt text must come from the illustrations prompt bundles, with scene and task/query layers selected deterministically and recorded in metadata.
  • Render randomness, sampled fonts/styles, query operands, and verifier payloads must be explicit in the instance trace.
  • Distractor/context text may be rendered only when it is part of the scene grammar and must not be treated as annotation unless it is the queried visual witness.
