A guarantee you can rely on

Every function and macro documented in this guide degrades gracefully when its owning feature is off — it never throws and never stops existing. Core ships some functionality behind an internal kill-switch system (not exposed to you directly) that lets it disable a half-finished or misbehaving feature without warning. When that happens, a function documented here falls back to whatever the base game's own standard behavior would be, not an error. You can call anything in this guide without defensively checking "is this feature currently on" first — that check already happened inside Core.
