Runtime verification · October 15, 2026

The world commits.

A real Finalverse Mac test over the hosted MutSea runtime: reviewed co-building, persistent memory and guarded Undo.

Captioned still-image recap from actual native tests; not a continuous screen recording. Video is served by GitHub Releases. Download MP4.

Lumi confirms the 147-part reading nook created through the authenticated native World API
A reviewed composition is compiled from approved content, validated and committed as the controller's objects.
The native world after guarded Undo with Lumi acknowledging the removal
Undo removes the recorded creation. Native counts return from 570 to the 423-part baseline.

Authority and continuity

The hosted runtime keeps Lumi state in a dedicated PostgreSQL database. Private Unix sockets connect the simulator, citizen runtime and AI gateway; world tools retain verified HTTPS and explicit controller checks. No public AI control port or cloud key is exposed by the client.

External TLS/login/UDP verification checked all 147 parts, transforms, ownership and semantics after server/runtime restarts. The completed goal, memory and WorldLine persisted. The final Mac test then confirmed actual rendering and Undo.

One configured controller and a private pilot. This is not an open public agent platform, managed-hosting launch or all-device performance claim.
