task_illustrations__isometric_farmstead__terrain_elevation_extremum_label

Summary

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

Task Contract

Selects the lettered terrain tile at the requested elevation extremum in an isometric farmstead scene. Each scene samples an active elevation range from 0..1 or 0..2.

Program Contract

Program: select(label, extremum(level(tile), mode=highest|lowest), tile in lettered_ground_tiles); scene=isometric_farmstead; scope=terrain_elevation_extremum_label

Candidate set: the visible illustrated scene objects, people, regions, tiles, patches, labels, and option panels inside the terrain_elevation_extremum_label objective scope. Operands: visible scene state and prompt-bound operands named by label, extremum, level, tile, mode, highest, lowest, lettered_ground_tiles, isometric_farmstead, terrain_elevation_extremum_label plus the active query_id branch. Operation: evaluate select 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 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: highest_terrain_tile, lowest_terrain_tile.

Reasoning Operations

Families: ranking

Query Branches

Query id Program schema
highest_terrain_tile select(label, max(level(tile)), tile in lettered_ground_tiles); scene=isometric_farmstead; scope=terrain_elevation_extremum_label
lowest_terrain_tile select(label, min(level(tile)), tile in lettered_ground_tiles); scene=isometric_farmstead; scope=terrain_elevation_extremum_label

Program Metadata

  • Program signatures: select.spatial_elevation_extremum
  • Base program contract: select(label, extremum(level(tile), mode=highest|lowest), tile in lettered_ground_tiles); scene=isometric_farmstead; scope=terrain_elevation_extremum_label
  • Parameter axes: canvas_profile, candidate_count=4, candidate_tile_ids, active_level_range, layout_family, terrain_level, extremum_mode
  • Arguments:
  • tile: visible lettered terrain tile; allowed generated candidate terrain tiles are plain grass tiles not occupied by farm objects, inside a same-level connected terrain region of at least six tiles, and supported by same-level neighbors on both grid axes; source scene_ir.tiles
  • level: integer terrain elevation; allowed active subset of 0|1|2; source scene_ir.tiles
  • mode: extremum operator; allowed highest|lowest; source query_id
  • Argument metadata status: curated
  • Supported query ids: highest_terrain_tile, lowest_terrain_tile

Answer Contract

  • Answer schema: option_letter
  • Generator answer_gt.type: option_letter
  • The answer is the letter on the unique candidate terrain tile whose ground level is highest or lowest as requested by the query branch.

Annotation Contract

  • Annotation schema: bbox
  • Generator annotation_gt.type: bbox
  • Annotation contains one bounding box around the selected terrain tile, not the letter badge and not any contextual farm object.

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 refer to ground or terrain tiles so object height is not confused with terrain elevation.
  • Render-only attributes such as palette, canvas profile, active max level, layout family, connected farm patch placement, farm animal/tree placement, tile geometry, and label font must not be query ids.
  • Tile levels, active levels, layout family, connected farm patches, context farm objects, candidate tile ids by label, candidate levels by label, selected label, selected tile id, selected tile bbox, projection metadata, and the scalar bbox annotation must be recorded in the trace.
