Call as
Platform.runes.finite(value)
Record the dependency Platform.runes.finite, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.

Editions
Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.
It reads no game API directly.
