Public Taxonomy

1. Domain: puzzles
2. Scene id: pipe_flow
3. Source scene: pipe_flow
4. Task id: task_puzzles__pipe_flow__pipe_flow_repair_tile_label

Query Contract

1. Supported query_id: single
2. Internal question format: pipe_flow_repair_tile_label
3. Prompt asks for the labeled 2x2 pipe/conduit repair option that fills the black missing region as drawn, without rotation or flipping, and repairs flow from the green start marker to the red triangular finish flag.
4. Internal variation:
5. grid_size_variant: 5x5|6x6|7x7
6. gap_size_variant: fixed 2x2
7. scene_variant: water_pipe|circuit_trace|industrial_conduit
8. option labels: exactly four options A..D
9. board topology: one visible start-to-finish path with no branch offshoots
10. rotations and flips are not allowed when testing whether an option fits.
11. option occupied cells are complete pipe tiles with two or more openings; one-opening partial pipe cells are rejected.

Program Contract

Program: select_label(as_drawn_2x2_pipe_repair_option, rule=connect_start_to_finish_without_rotation); scene=pipe_flow; scope=pipe_flow_repair_tile_label

Candidate set: the visible pipe tiles, pipe connectors, start/finish markers, misrotated or missing tile cue, and labeled options inside the pipe_flow_repair_tile_label objective scope. Operands: visible scene state and prompt-bound operands named by as_drawn_2x2_pipe_repair_option, connect_start_to_finish_without_rotation, pipe_flow, pipe_flow_repair_tile_label. Operation: evaluate select_label over the candidate set using the visible states, constraints, transforms, comparisons, counts, paths, or option-selection rules encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the option_letter schema; the capital-letter label on the correct 2x2 repair option panel. Annotation witnesses: annotation uses the bbox_map schema; not used because the task has two semantically distinct visual witnesses. Query ids: single.

Reasoning Operations

Families: topology

Answer And Annotation

1. answer_gt.type = option_letter
2. answer_gt.value is the capital-letter label on the correct 2x2 repair option panel.
3. annotation_gt.type = bbox_map
4. Annotation schema: bbox_map
5. Annotation contains exactly two keys:
6. selected_option: bbox around the correct option panel.
7. missing_gap: bbox around the black 2x2 missing region.
8. scalar_annotation_checked = true; scalar annotation is not used because the task has two semantically distinct visual witnesses.

Trace Contract

1. scene_ir.entities includes one pipe_flow_panel, one pipe_flow_missing_region, one pipe_flow_tile per visible pipe/conduit tile, one pipe_flow_start_marker, one pipe_flow_finish_flag, and four pipe_flow_option_panel entities.
2. Internal render_map.item_bboxes_px contains all option panel ids and the missing-region id used for verifier projection.
3. Trace sidecars expose the projected pixel boxes through annotation_gt / projected_annotation; internal item ids may be sanitized from persisted execution_trace.
4. execution_trace.tiles records each visible tile's current openings and required path openings. For this task, every visible pipe tile belongs to the single main path.
5. execution_trace.branch_cells and execution_trace.branch_terminal_cells are empty because branch offshoots are disabled for this repair task.
6. execution_trace.gap_size_variant records the fixed 2x2 missing-region size.
7. execution_trace.option_specs records the four 2x2 option pieces, records that rotation is not allowed, stores whether each option connects in place, rejects one-opening partial pipe cells, and identifies the unique correct option as drawn.

Prompt Contract

1. Bundle: puzzles_pipe_flow_v1
2. Scene key: pipe_flow
3. Task key: pipe_flow_repair_tile_label_query
4. Query key: pipe_flow_repair_tile_label
5. Prompt wording should explain that flow passes through matching tile-edge openings, that options must be used as drawn without rotation or flipping, and that exactly one 2x2 option fills the black gap to connect the green start marker to the red triangular finish flag.
