Detailed Description

Validated CUDA device identity with cached immutable capabilities.

A Device is a cheap value containing only a device ordinal. get() validates that ordinal and initializes its process-wide capability cache. It does not own streams, schedulers, provider handles, memory pools, or allocations.
