Engine SpecsJava 1.21
- ▸Spawning spheres computed from actual Minecraft voxel distance checks (no approximation)
- ▸Repeater clock decomposition uses integer-exact tick arithmetic
- ▸Nether coordinate ratio is precisely 8:1 on X and Z — Y is independent
- ▸All calculations version-pinned to Java 1.21 game rules
