task_geometry__survey_traverse__traverse_area_value

Contract

1. Domain: geometry
2. Scene id: survey_traverse
3. Task id: task_geometry__survey_traverse__traverse_area_value
4. Supported public query_id: single
5. Answer schema: integer
6. Annotation schema: bbox_map

Program Contract

• survey_traverse_area_value(visible_traverse_shape, visible_field_note, branch=offset_trapezoid_area) -> enclosed_area; scene=survey_traverse; scope=traverse_area_value

Reasoning Operations

Families: formula_evaluation

Prompt Bundle

• Prompt text is loaded from the v1 scene prompt bundle configured for survey_traverse.
• Prompt modes: answer_only and answer_and_annotation.
• Internal trace branch: offset_trapezoid_area.

Annotation

Prompt-facing annotation uses pixel-space box witnesses. Map annotation binds the visual area witnesses:

• traverse_region
• field_note_region Chainages, offsets, station labels, and field-note text remain visible diagram content plus private verifier metadata.

Determinism

Generation is deterministic for a fixed seed, params, config, and prompt bundle version.
