Summary

• Domain: illustrations
• Scene id: isometric_farmstead
• Implementation source scene: isometric_farmstead
• Implementation source: src/trace_tasks/tasks/illustrations/isometric_farmstead/highest_terrain_tile_count.py

Task Contract

Counts the visible top-surface terrain tiles that make up the highest elevation layer in an isometric farmstead.

Program Contract

Program: count(tile, level(tile)=max(level(terrain_tiles)) and tile in visible_top_surface_tiles); scene=isometric_farmstead; scope=highest_terrain_tile_count

Candidate set: the visible illustrated scene objects, people, regions, tiles, patches, labels, and option panels inside the highest_terrain_tile_count objective scope. Operands: visible scene state and prompt-bound operands named by tile, level, max, terrain_tiles, visible_top_surface_tiles, isometric_farmstead, highest_terrain_tile_count. Operation: evaluate count over the candidate set using the visible illustrated objects, regions, layout relationships, counts, patch/tile transforms, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the integer 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: single.

Program Metadata

• Program signatures: count.spatial_elevation_tiles
• Base program contract: count(tile, level(tile)=max(level(terrain_tiles)) and tile in visible_top_surface_tiles); scene=isometric_farmstead; scope=highest_terrain_tile_count
• Parameter axes: canvas_profile, target_count=4..8, highest_layer_shape, active_level_range, layout_family
• Arguments:
• terrain_tiles: all visible terrain tile top faces; source scene_ir.tiles
• level: integer terrain elevation; source scene_ir.tiles
• highest_layer: the connected set of visible terrain tiles at the maximum level; source scene_ir.tiles
• Argument metadata status: curated
• Supported query ids: single
• Internal prompt/query key: highest_terrain_tile_count

Answer Contract

• Answer schema: integer
• Generator answer_gt.type: integer
• The answer is the number of visible top-surface terrain tiles on the highest elevation layer.

Annotation Contract

• Annotation schema: bbox
• Generator annotation_gt.type: bbox
• Annotation contains one bounding box around the whole highest-elevation top layer. It is not a per-tile bbox set, and it must not include lower-level side faces as the intended witness.

Prompt And Trace Requirements

• Prompt text must come from src/trace_tasks/resources/prompts/illustrations/isometric_farmstead/illustrations_isometric_farmstead_v0.json.
• Public prompts must ask for the count of visible tiles on the highest elevation layer.
• The renderer must keep the highest layer as one connected clean plateau and reserve highest-layer tiles from farm patches and context objects.
• Target level, counted tile ids, counted tile bboxes, highest-layer bbox, answer count, projection metadata, and the scalar bbox annotation must be recorded in the trace.
