task_three_d__warehouse__nearest_candidate_to_reference_label

Summary

• Domain: three_d
• Scene id: warehouse
• Public task id: task_three_d__warehouse__nearest_candidate_to_reference_label
• Supported query_id: closest_object_to_reference, closest_object_to_robot
• Answer schema: option_letter
• Annotation schema: bbox

Program Contract

Program: select(label(candidate_items, argmin(ground_plane_surface_gap_to_reference))); scene=warehouse; scope=nearest_candidate_to_reference_label

Candidate set: the visible 3D objects, surfaces, room/street/warehouse structures, spatial anchors, markers, and labeled options inside the nearest_candidate_to_reference_label objective scope. Operands: visible scene state and prompt-bound operands named by label, candidate_items, argmin, ground_plane_surface_gap_to_reference, warehouse, nearest_candidate_to_reference_label plus the active query_id branch. Operation: evaluate select over the candidate set using the finalized 3D scene state, camera projection, object identities, spatial relations, counts, distances, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the option_letter schema; generation binds a unique final answer. Annotation witnesses: annotation uses the bbox schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: closest_object_to_reference, closest_object_to_robot.

Reasoning Operations

Families: ranking, spatial_relations

Prompt And Trace

The prompt bundle is three_d_warehouse_v1 under src/trace_tasks/resources/prompts/three_d/warehouse/. The trace records camera pose, projection frame, scene variant, aisle heading, reference metadata, candidate labels/types, robot designs/headings/colors where applicable, nearest-distance order, per-label distances to the reference, selected object id, projected bboxes, and option-panel descriptors/bboxes.

Determinism

Generation is deterministic from instance_seed, explicit params, config defaults, prompt bundle, and code versions. Answer and annotation come from the same finalized 3D warehouse scene trace.
