WorldTile runtime map

✅ Verified baseline map

Verified useful relationships include readable x, y, Height, cur_tile_type, zone, chunk, region and neighboursAll on the tested map. Terrain/biome resolution uses cur_tile_type → TileTypeBase.biome_asset → BiomeAsset.

The tested default map had 65,536 unique coordinates in a 256×256 rectangle, but map size is not a universal contract when Custom Worldsize is installed.

Lifecycle lesson: a WorldTile can remain the same managed object through save/reload and repeated same-size world generation. Identity replacement is not a completion signal. Conversely, do not assume reuse on future versions: revalidate current membership/state.

Heavy full-map reflection scans should be chunked and should never run every wait-loop frame.
