VoxelCore Current Status

Documentation baseline: VoxelCore main at 452b569 · 14 September 2026.
Repository: https://github.com/VoxelHorizons/VoxelCore

Snapshot

This documentation was reconciled against the repository tree, merged pull requests and implementation on 14 September 2026. The baseline commit is 452b569, which is the merge of PR #16, Hide unbound definitions from the item list.

The two newest merged changes materially affect the public contract:

• PR #16 — unbound list filtering: /voxelcore admin item list now includes only definitions whose compiled bound value is true. Unbound base/inheritance definitions remain in the registry and can still be inspected/referenced; they are simply omitted from that user-facing list.
• PR #15 — Minecraft/Paper 26.2: VoxelCore now has a dedicated voxelcore-v26_2 distribution, exact 26.2 platform adapter, Java 25 compile target, mc-26.2 resource-pack target with format 88.0, modern range metadata, and a seventh live-server smoke row.

MVP acceptance surface

Implemented and tested now:

content packs + assets
        ↓
deterministic discovery + bounded YAML parsing
        ↓
strict schema validation
        ↓
single-parent inheritance + compilation
        ↓
immutable ItemDefinitionRegistry
        ↓
stable render-allocation reconciliation
        ↓
platform preflight validation
        ↓
atomic ContentSnapshot publication
        ↓
ItemManager + version adapter
        ↓
ItemStack with persistent ContentID

same definitions + allocation authority
        ↓
deterministic Java resource-pack compiler

Validated live-server matrix

The smoke matrix now covers seven exact versions: 1.12.2, 1.13.2, 1.14.4, 1.19.4, 1.20.5, 1.21.4 and 26.2. See Products/Voxel-Horizons/VoxelCore/Version-Support.

Documentation discrepancy to be aware of

At this snapshot, the repository README.md was synchronised by PR #14 before PR #15 added 26.2. Its version-family and resource-pack-target tables therefore stop at 1.21.4. The code, Maven reactor, CI changes and merged PR #15 establish 26.2 support; this wiki reflects that newer state.

Not implemented as part of this MVP

• placed custom-block lifecycle;
• furniture/display placement lifecycle;
• vehicles;
• crops;
• GUI/menu framework and Bedrock-specific presentation;
• Geyser/Floodgate item mappings;
• true Minecraft combat AttributeModifier authoring;
• richer typed metadata for potions, skulls, books, maps and fireworks;
• generic low-level post-1.20.5 component escape hatches;
• HavenCore compatibility/import aliases.

These belong to Products/Voxel-Horizons/VoxelCore/Roadmap-and-Scope, not the current supported contract.
