Detailed Description

Persistent zero-copy scratch used by owning synchronous result wrappers.

The scratch is allocated as mapped pinned host memory. Kernels write through the mapped device pointer, so synchronous summary(), cardinality(), and hybrid_cardinality() calls only launch and synchronise without a device-to-host copy.
