task_geometry__measuring_tools__protractor_angle_value

Contract

1. Domain: geometry
2. Scene id: measuring_tools
3. Supported query_ids: single
4. Answer schema: integer
5. Annotation schema: point_map

Program Contract

• read_visible_measurement_tool(tool=protractor, candidate=marked_angle_on_carrier_shape, unit=degrees, operation=read_protractor_tick, output_role=angle_measure_integer, annotation_witness={angle_vertex,protractor_reading_tick}); scene=measuring_tools; scope=protractor_angle_value

Reasoning Operations

Families: formula_evaluation

Prompt Bundle

• Prompt text is loaded from the scene prompt bundle configured for measuring_tools.
• Prompt modes: answer_only and answer_and_annotation.

Annotation

Prompt-facing annotation uses pixel-space witnesses only. Annotation must be a keyed point map with angle_vertex and protractor_reading_tick.

Internal Sampling

The carrier shape is internal construction metadata, not public query variation. Supported carrier shapes are triangle and quadrilateral.

Determinism

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