Bounded state
Expose only what the local runtime makes available to the current workflow.
VANTA · Engine
A runtime for worlds that can answer back.
Run worlds, simulation, state, and native systems through an authoritative runtime. The host owns the transition; tools and models propose within a boundary.
Runtime surface
The world remains the source of truth.

That separation keeps an interesting simulation from quietly becoming an unreviewed authority path.
Explicit transitions
Candidate actions meet the host’s rules before they can change the world.
Traceable output
Keep design target, local evidence, and public claim distinguishable.
