Server Administration

MarieLib fully supports dedicated NeoForge servers. Commands register under the consuming mod's id (e.g. /nourished for Nourished).

---

📦 Installing MarieLib on a Server

Both the consuming mod and MarieLib must be installed:

Component	Required on
MarieLib	Server + all clients
Consuming mod (e.g. Nourished)	Server + all clients

Verify matching versions of Minecraft, NeoForge, MarieLib, and the consuming mod before opening to players.

🌐 Server-Authoritative Tracking

MarieLib uses a server-authoritative architecture. The server controls:

• Value levels and decay
• Tracking profiles
• Source classifications
• Datapack-loaded definitions
• Compatibility settings

Clients receive synchronized data from the server. See Multiplayer & Sync.

---

🔄 Reloading

After datapack changes:

/<modId> reload

If only classifications changed:

/<modId> invalidatecache

may be sufficient.

---

🔒 Module Locks

Modpack authors can lock config modules server-side:

{
  "marie_schema_version": 1,
  "locked": ["enableEffects", "enableDecay"],
  "server_only": ["bonusEffectThreshold"]
}

Path: data/<ns>/<modId>/module_locks/<id>.json

🔍 Diagnostics Workflow

When investigating issues on a live server:

1. Hold the problematic item
2. Run /<modId> debug held
3. Review config/<modId>/debug/trace_dump.txt
4. Run /<modId> diagnostics for datapack validation
5. Check config/<modId>/unassigned_sources.txt for gaps

---

✅ Recommended Workflow

1. Install matching MarieLib + consuming mod versions on server and clients
2. Verify datapacks load successfully
3. Run /<modId> diagnostics after major updates
4. Use classification traces when investigating food issues
5. Keep compat overrides under version control
6. Run /<modId> invalidatecache after scanner config changes
