Contract

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

Program Contract

• survey_station_elevation_value(visible_station_profile, visible_field_note, branch=leveling_station_elevation) -> target_station_elevation; scene=survey_traverse; scope=station_elevation_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: leveling_station_elevation.

Annotation

Prompt-facing annotation uses pixel-space bbox witnesses. Map annotation binds the visible station profile and field-note region:

• station_profile
• field_note_region

Numeric elevations, staff readings, 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.
