Building Structures

Primary Method: Schematics

Use build_schematic() for all structures. See building-with-schematics skill for schema details.

Critical: Floor Y = Ground Y

Floor REPLACES ground, NOT sits on top!

WRONG: Y=65 floor, Y=64 foundation, Y=63 grass (elevated!)
RIGHT: Y=65 walls, Y=64 floor REPLACES grass, Y=63 dirt

Workflow: get_surface_level(x,z) → anchor at that Y
