Compatibility Matrices & Toolchains

State: current development/testing cells

This matrix lists packaged loader cells for VonixGuardian 3.0.0-m1 and Vonix Server Utilities 2.0.2. It is a documentation table, not a live compatibility feed.

Current Dev/Test

1. Unified matrix

Minecraft	Loader	VonixGuardian	VSU	Java	Toolchain
26.1.2	NeoForge (26.1.2.93)	3.0.0-m1	2.0.2	Java 25	ModDevGradle 2.0.140
1.21.1	NeoForge	3.0.0-m1	2.0.2	Java 21	net.neoforged.moddev jarJar / Architectury
1.21.1	Fabric	3.0.0-m1	2.0.2	Java 21	Fabric Loom JarInJar (META-INF/jars)
1.20.1	Forge	3.0.0-m1	2.0.2	Java 17	ForgeGradle 6 jarJar / Architectury

1.18.2	Fabric	3.0.0-m1	2.0.2	Java 17	Fabric Loom JarInJar (META-INF/jars)

2. Java class versions

Minecraft servers reject mismatched class-file versions:

• Java 17 (class version 61.0): required for 1.18.2, 1.19.2, and 1.20.1.
• Java 21 (class version 65.0): required for 1.21.1 (Fabric and NeoForge).
• Java 25 (class version 69.0): required for 26.1.2 (NeoForge).

java -version

3. Optional integrations

Neither mod hard-depends on these products. Behavior when they are absent is documented below.

LuckPerms

• Status: supported through reflection.
• Behavior: LuckPerms classes are never hard-imported. Without LuckPerms, VonixGuardian uses defaultOpLevel: 3. VSU uses union semantics (HasLuckPermsNode OR OpLevel >= opFallback).

Curios and Trinkets

• Status: VSU /accsee bridge.
• Behavior: Curios on Forge/NeoForge, Trinkets on Fabric. If neither is installed, /accsee reports that no accessory provider is available.

Modded griefing attribution

• Status: VonixGuardian universal attribution chain.
• Behavior: Player blame is resolved through vanilla ownership interfaces (getControllingPassenger(), TamableAnimal.getOwnerUUID(), OwnableEntity). Per-mod adapters are not required. Coverage of a specific third-party mechanic is not a compatibility guarantee.

WorldEdit

• Status: soft-dependency in VonixGuardian.
• Behavior: r:#worldedit and r:#we are accepted by the parser. In 3.0.0-m1 they fall back to an unbounded global radius rather than a WorldEdit selection box.

4. Modpack validation boundary

Known validation boundary: external Fabric 1.21.1 server pack

In a headless Fabric 1.21.1 pack test, VonixGuardian loaded with zero hopper or dispenser errors. The pack itself did not reach readiness because an unrelated third-party mixin failed: owo.mixins.json:MainMixin afterQuiltHook injection failed.

Treat this as an external pack dependency boundary, not as a VonixGuardian crash.
