A sub-agent that reproduces and fixes Project Zomboid recipe bugs with headless evidence and no human in the loop — what it’s built on, what it can do, its hard limits, and the dark spots that produce a confident wrong answer.

A scripting channel into a running dedicated server, a way to perform real crafts with no client or player, and the duplication and silent-no-op bug classes they surfaced while porting a mod to Build 42.
