World state
Nova
Nova worlds, parcels, buildings, avatars, and region indexes are durable chain state. The Explorer 3D city is a visualization layer, not the source of truth.
Launch scope
World creation, parcel claim/transfer, building deployment/removal, and avatar updates are deterministic. Auction lifecycle storage exists, but bidding remains fail-closed until escrow and settlement policy are complete.
Clients should render chain-backed parcel/building/avatar state from nova_* RPC methods when available.
