OverlayLib

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

Evidence

Ran on Kiln's test stand (2026-11-04): OverlayLib did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/client/command/v2/ClientCommandRegistrationCallback.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file overlaylib-0.12.1+26.3.jar. The scan reads the mod's classes; it does not run them.
