10. Memory without another billion-dollar mistake

Locals, GC heap, ref/out, and an honest preview of FFI—without pretending we are Rust.

Memory without another billion-dollar mistake

Another billion-dollar mistake is treating one memory strategy as moral law. Beskid picks: stack activations, GC-managed heap, ref/out, and rules for fibers—documented in Language meta memory model and realized in Execution runtime memory.

We are not shipping “just use Rust” as the user tutorial. We are shipping predictable language law and a collector you can reason about.
