World map baseline — WorldTile, terrain, biome and map services

✅ Verified — current baseline

WBML-0021 — WorldTile API

25 / 0 / 0 PASS. MapBox.tiles_map exposed 65,536 live tiles on the tested map. A sample at (1,1) had readable coordinates/height, a TileZone, eight neighboursAll, and neighbour reciprocity passed. A direct WorldTile → BiomeAsset reference was not required and was kept observational.

WBML-0022 — Terrain / Biome

30 / 0 / 0 PASS. The real route was:

WorldTile.cur_tile_type
→ TileTypeBase
→ TileTypeBase.biome_asset
→ BiomeAsset

BiomeLibrary.pool_biomes observed count=60. The run saw 24 distinct live TileTypeBase-derived references. Across 8192 height reads the observed range was 0..177; this is world-state data, not a universal range. Sample biome_grass.getTileCount() returned 1105.

WBML-0023 — map services

28 / 0 / 0 PASS. All 65,536 tile coordinates were readable and unique. The tested map was exactly x=0..255, y=0..255 — 256×256. A sample tile resolved TileZone, MapChunk and MapRegion. Observed structure:

• TileZone: 64 tiles;
• MapChunk: 256 tiles;
• MapRegion: 4 zones;
• TileManager, MapChunkManager, WorldTilemap: all resolved.

Sample state stayed stable 100/100 and tile count 1000/1000. The 256×256 shape is an observation of this map, not a fixed contract when Custom Worldsize is present.
