Module mappings 

yog mappings (docs/design/nanites.md, “Names”): a host’s mapping table — Mojang’s names → the host’s run-time names — from Mojang’s mappings and the loader’s (Fabric’s intermediary, Forge’s SRG), fetched once into Yog’s cache.

Functions

join

Mojang’s classes joined with rt: each class and member by Mojang’s name, renamed as rt names it (keep_classes: Forge keeps Mojang’s class names at run time, renaming members only).

table

The table for Minecraft mc on a host running runtime_ns names.
