Forge Config API Port

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): it stopped at com.electronwill.nightconfig.core.UnmodifiableConfig, a class from a jar nested inside the mod; Kiln does not unpack nested jars yet.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file ForgeConfigAPIPort-v26.3.1-mc26.3.x-Fabric.jar. The scan reads the mod's classes; it does not run them.
