task_symbolic__clock__equivalent_time_label

1) Identity

1. Domain: symbolic
2. Scene id: clock
3. Scene: clock
4. Task id: task_symbolic__clock__equivalent_time_label
5. Objective: choose the labeled option display that shows the same time as a reference clock display.

Program Contract

Program: clock.equivalent_time_label(scene=clock, scope=reference_clock_display_with_six_options, query=analog_reference_digital_options|digital_reference_analog_options, output=option_label)

Candidate set: the six visible option displays labeled A..F. Operands: the reference time and the time shown by each option display. Operation: compare all option times to the reference time and select the unique equivalent option. Output binding: answer is the selected option label. Annotation witnesses: a bbox_map with reference and correct_option roles. Query ids: analog_reference_digital_options, digital_reference_analog_options.

Reasoning Operations

Families: formula_evaluation, matching

2) Scene + Task Contract

1. Public branch metadata: query_id
2. Supported public query_id: analog_reference_digital_options, digital_reference_analog_options
3. Supported non-semantic visual axes:
4. scene_variant: classic|minimal|outline
5. style_variant: accented|marker|studio
6. accent_color_name: shared symbolic clock colors
7. digital_display_palette: display color palette
8. answer_gt.type: string
9. Answer schema: one option label from A through F.
10. annotation_gt.type: bbox_map
11. Annotation schema: bbox_map with roles reference and correct_option
12. Scene contract:
13. the reference appears above six visual options,
14. exactly one option shows the same time as the reference,
15. distractor options use distinct times separated by the configured gap.

3) Prompt Contract

1. Bundle: symbolic_clock_v1
2. scene_key: clock
3. task_key: clock_equivalent_time_label_query
4. Required slots:
5. scene: object_description
6. answer output: json_output_contract_answer_only, answer_hint, json_example_answer_only
7. answer+annotation mode: json_output_contract, annotation_hint, answer_hint, json_example
8. Modes: answer_only, answer_and_annotation

4) Annotation + Trace Contract

1. Prompt-facing annotation is a role-bound bbox_map.
2. reference marks the reference clock/display; correct_option marks the matching option display.
3. Distractor options and option labels are not prompt-facing annotation.
4. projected_annotation includes bbox_map and pixel_bbox_map.
5. render_map includes reference, option, and correct-option bboxes.

5) Determinism + Tests

1. Deterministic sampling/rendering from instance_seed.
2. Answers and annotation come from the finalized rendered reference and options.

4. Source-layout contract tests: tests/test_public_source_layout_contracts.py
