### Added - **Guardrails system** to prevent accidental modifications to critical classes that could corrupt worlds or crash the JVM - Protects chunk generation classes (`ChunkGenerator`, `NoiseBasedChunkGenerator`, `WorldGenRegion`, `LevelChunk`, `ChunkStatus`) - Protects palette container classes (`PalettedContainer`, `LinearPalette`, `HashMapPalette`, `Palette`) - Protects mixin system internals (`org.spongepowered.asm.*`) - Protects JVM/classloader internals (`java.lang.ClassLoader`, `sun.misc.Unsafe`, `jdk.internal.*`) - Protects threading classes (`BlockableEventLoop`, `TickTask`) - Protects world persistence classes (`LevelStorageSource`, `net.minecraft.nbt.*`, `LevelData`) - New `guardrails` config section with: - `enabled` — master toggle (default: `true`) - `bypassProtectedClasses` — override protection at your own risk (default: `false`) - `additionalProtectedPatterns` — add your own protected class prefixes - `excludeFromProtection` — selectively unprotect specific classes (requires bypass) - Early config validation logs warnings at startup when protected classes are referenced - Guardrails block target-class blacklisting and method removal/nop on protected classes by default
