space
exists
Check whether a product space exists on a branch.
strata space existsdb.spaces.exists(name: 'str') -> 'bool'wire space_exists
Reports whether the named product space is cataloged on the target branch. A missing space is `false`, not an error; reserved names are rejected with `invalid_argument.engine.product_space_reserved`.
Status commands return a scalar or compact status payload and do not mutate database state.
