Disables all Singleplayer cheating

About this Mod
HardGrind is a singleplayer discipline mod for Fabric 1.21.9.
It removes every shortcut that could ruin your grind — no /op, no /gamemode, no cheating.
Even in singleplayer, you play by the same rules as on a real public survival server.
Main Features
OP is dead: All operator permission checks always return false.
Command lockdown: Blocks /op, /deop, /gamemode, /give, /tp, /summon, /effect, /xp, /enchant, /locate, and /gamerule.
Permanent survival: Automatically switches players back to Survival mode every tick if they somehow escape.
Lightweight: No configuration, no UI, no nonsense — just a strict singleplayer survival environment.
Intended Use
For players who want the real grind experience in singleplayer — no temptation, no exceptions.
Perfect for those training for multiplayer servers or challenge worlds.
Extra-hardening (brief)
For stronger protection against casual bypassing, it is recommended to secure the world’s ops.json so operator entries cannot be persisted. Disabling the mod will bypass its protections; file-level hardening makes casual tampering harder but cannot stop someone with full filesystem/admin access.

HardGrind server crashes on startup – what to do?

Is HardGrind compatible with fabric?
HardGrind officially supports fabric for Minecraft 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with HardGrind – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HardGrind consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
