Model proposes, runtime decides.

Reliable execution starts when reasoning and action are separated.

A capable model can suggest good next steps, but suggestion is not the same as permission. Systems fail when those two are treated as one decision.

When the runtime evaluates each proposed action, behavior becomes more predictable. You stop depending on confidence language and start depending on explicit checks.

This is the difference between an assistant that sounds correct and a system that behaves correctly.

What this changes in practice: design your agent so every action crosses a runtime gate before it touches the real world.
