task_symbolic__clock__time_extremum_label

1) Identity

1. Domain: symbolic
2. Scene id: clock
3. Scene: clock
4. Task id: task_symbolic__clock__time_extremum_label
5. Objective: identify the labeled analog clock with the earliest or latest shown time.

Program Contract

Program: clock.time_extremum_label(scene=clock, scope=labeled_analog_grid, query=earliest_time_label|latest_time_label, output=clock_label)

Candidate set: the six visible labeled analog clocks. Operands: the displayed time on each clock and the requested extremum direction. Operation: compare all shown times and select the unique earliest or latest clock. Output binding: answer is the selected visible clock label. Annotation witnesses: the scalar bbox of the selected clock face. Query ids: earliest_time_label, latest_time_label.

Reasoning Operations

Families: ranking

2) Scene + Task Contract

1. Public branch metadata: query_id
2. Supported public query_id: earliest_time_label, latest_time_label
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. answer_gt.type: string
8. Answer schema: one visible clock label.
9. annotation_gt.type: bbox
10. Annotation schema: scalar bbox
11. Scene contract:
12. six analog clocks are labeled with unique letters,
13. exactly one clock has the requested extremum time,
14. the extremum clock is separated by at least the configured comparison gap.

3) Prompt Contract

1. Bundle: symbolic_clock_v1
2. scene_key: clock
3. task_key: clock_time_extremum_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 the scalar bbox for the selected clock face.
2. Clock labels, non-winning clocks, hands on non-winning clocks, and panel background are not prompt-facing annotation.
3. projected_annotation includes bbox and pixel_bbox.
4. render_map includes clocks_by_label, winning_label, and winning_clock_bbox_px.
5. execution_trace records all visible clock labels and shown times.

5) Determinism + Tests

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