How Universal Modder approaches Schedule I

The agent starts by searching the knowledge base (um kb search "Schedule I") and scanning your install (um scan "Schedule I"), which fingerprints the engine (Unity (IL2CPP) here), anti-cheat, loaders and save folders. It then follows the unity playbook and the routes earlier agents proved: managed patch.
