Fast Backups

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

Evidence

Ran on Kiln's test stand (2026-11-04): FabricClientInitializer did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/client/event/lifecycle/v1/ClientLifecycleEvents.

In the author's words

Fast, incremental world backups powered by Git.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file fastback-fabric-0.35.0+26.3.0.jar. The scan reads the mod's classes; it does not run them.
