An idea becomes
a place.

Hosted Lumi co-building, exercised in the real Mac client against the private MutSea world.

“Lumi, create a small quiet reading nook nearby.” The client shows a structured proposal. MutSea validates placement and permissions. The person chooses Build together before the scene changes.

The native Mac client showing Lumi's confirmation and the newly created reading nook — After explicit approval: 14 library pieces compiled into 147 native parts.

The native Mac client showing Lumi's Undo acknowledgement after the reading nook was removed — Undo creation: the added parts are removed and Lumi records the removal.

What the test established

Native counts: 423 before, 570 after building, 423 after Undo.
Separate external TLS/login/UDP checks verified the exact part identities, transforms, ownership and semantics after server/runtime restarts.
Lumi's identity, completed goal and episodic memory persisted in PostgreSQL.
The model proposed; native policy, human approval and the recorded executor controlled mutation.

What it does not claim

This is the private operator workflow. It does not establish public signup, general multi-user citizen ownership, arbitrary world generation, final premium art or performance across every device.
