Variable MobileUserFlowSchema`Const`

MobileUserFlowSchema: Struct<
    {
        cancelOnBackground: Boolean;

        timeoutMs: optional<Number>;
    },

One running user flow, and the one declaration of its stored shape: the checkpoint schema below is the same schema, so a field added here cannot be dropped by the encoder. The interface is derived from the schema (the schema's Type) rather than written beside it.
