task_geometry__shape_reference__congruent_match

Contract

1. Domain: geometry
2. Scene id: shape_reference
3. Query id: single
4. Answer schema: option_letter
5. Annotation schema: point_set

Program Contract

• label(select_option(candidate_shapes, shape_relation(shape, reference_shape)=congruent_to_reference)); scene=shape_reference; scope=congruent_match

Reasoning Operations

Families: matching

Prompt Bundle

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

Annotation

Prompt-facing annotation is a point_set containing the selected polygon's visible vertices in pixel coordinates. The reference shape, labels, relation rule, graph coordinates, and symbolic shape metadata remain private verifier metadata.

Determinism

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