Evidence

Ran on Kiln's test stand (2026-11-04): seamlesschunksFabric did not start: java.lang.NoClassDefFoundError: net/minecraft/server/MinecraftServer.

What it needs from Kiln

• Mixin
• net.minecraft.client.gui.components.Button
• net.minecraft.client.gui.components.Button.Builder
• net.minecraft.client.gui.components.Button.OnPress
• net.minecraft.client.gui.components.Checkbox
• net.minecraft.client.gui.components.Checkbox.Builder
• net.minecraft.client.gui.screens.TitleScreen
• net.minecraft.client.multiplayer.PlayerInfo
• net.minecraft.util.ARGB
• net.minecraft.util.Mth
• net.minecraft.server.MinecraftServer
• Minecraft.execute()
• GuiGraphicsExtractor.centeredText()
• Screen.extractRenderState()
• ClientPacketListener.getPlayerInfo()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)

In the author's words

Smoother chunk loading with network-aware send rates, multiplayer fair share, and in-game tuning.
