Workshop

Most of this site argues about agents and verification. This is the other pole: native Swift and Metal work, made because it was worth making. The two are different kinds of work, and keeping them in separate rooms is the honest move; flattening them into one grid would lie about where the energy goes.

These are local build captures, not store listings. No App Store availability is claimed here; public links and review status go up only when they are independently verified.
