# VoxelCore


> **Documentation baseline:** VoxelCore `main` at `452b569` · 14 September 2026.

VoxelCore is the version-aware content foundation for Voxel Horizons. The current implemented milestone is the **custom item/content MVP**: deterministic content-pack loading, validated inheritance, immutable runtime snapshots, stable item identity, version-specific `ItemStack` creation, stable render allocation, deterministic Java resource-pack compilation and safe atomic reloads.

It is intentionally **not yet** the full historical HavenCore feature set. Placed blocks, furniture, vehicles, crops, GUI/menu presentation, Bedrock/Geyser mappings and the broader legacy migration remain later systems.

## Core invariant

A VoxelCore item is identified by its namespaced **ContentID**, not by its model path or Custom Model Data value. Rendering is version-specific presentation state layered over stable gameplay identity.
