Just Core

Just Core is the server-side API and shared infrastructure layer for Just Vanish, Just Essentials, and future Just mods on Minecraft 1.21.1 with NeoForge.

API 2

• Stable JustCoreApi entry point
• Companion-module registry
• Mutable player-state providers for features such as vanish
• Central append-only audit log at world/justcore/audit.jsonl
• Public StaffActionEvent
• /justcore info and /justcore modules diagnostics
• No client installation required

Just Core 0.2.0 is required by Just Vanish 1.3.1+ and Just Essentials 0.3.1+. It keeps shared contracts, module discovery, player states, and staff auditing independent from either feature mod.

Documentation

Installation, API concepts, modules, player states, auditing, events, and versioning are maintained in the Just Core Wiki.
