CB: Compressed Blocks

Evidence

Ran on Kiln's test stand (2026-11-04) without the mods it depends on: it stopped at com.electronwill.nightconfig.core.ConfigFormat, a class from another mod or library the stand did not have.

What it needs from Kiln

• net.fabricmc.fabric.api.client.item.v1.ItemTooltipCallback
• net.fabricmc.fabric.api.creativetab.v1.FabricCreativeModeTab
• net.minecraft.SharedConstants
• net.minecraft.WorldVersion
• net.minecraft.core.component.DataComponents
• net.minecraft.network.chat.Style
• net.minecraft.world.item.CreativeModeTab.Builder
• net.minecraft.world.item.CreativeModeTab.DisplayItemsGenerator
• net.minecraft.world.item.CreativeModeTab.ItemDisplayParameters
• net.minecraft.world.item.CreativeModeTab.Output
• net.minecraft.world.item.Item.TooltipContext
• net.minecraft.world.level.block.HorizontalDirectionalBlock
• net.minecraft.world.level.block.RotatedPillarBlock
• org.apache.commons.lang3.tuple.Pair
• BuiltInRegistries.CREATIVE_MODE_TAB
• MutableComponent.withStyle()
• Item.Properties.component()
• BlockBehaviour.Properties.overrideDescription()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3)
