Defined in: [packages/common/src/local-first/Schema.ts:254](https://github.com/evoluhq/evolu/blob/215bf32284e302f2fc68bdcc9df57cc7df5a6fc3/packages/common/src/local-first/Schema.ts#L254)

App-owner registry schema with local tables for tests and examples.

Stores operational keys separately from optional recovery material. A null
secret represents an owner whose recovery material is managed elsewhere or
unavailable. Names are optional device-local labels; identicons can be
derived from the owner identity without an additional column.

This fixture does not define the production registry's persistence contract.
