EverArcade World Package v0.1
The world is the sovereign object. A world.evr package is portable continuity: contract, runtime metadata, genesis state, replay/receipt/state roots, continuity root, schemas, assets, and proofs.
The package is deterministic: files are ordered lexicographically, JSON files are emitted canonically by the CLI, and the archive hash is computed over the exact bytes of the EVRWORLD archive.
The lease is temporary infrastructure and never becomes world identity.
