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 eu.pb4.polymer.core.api.item.PolymerItem, a class from a jar nested inside the mod; Kiln does not unpack nested jars yet.

In the author's words

A library for my Server-Sided Fabric Mods. Contains a lot of very useful stuff for myself and other modders!

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file borislib-4.0.1+26.3.jar. The scan reads the mod's classes; it does not run them.
