The engine-inventory row was the CUDA blocker at the time of writing: `libcuda` filters the engine list it receives against the class list and expects the async copy engine to be present, because the secondary (async) -engine record is otherwise zeroed. That inventory is now complete; the -context-creation wait is later, in the completion path. See +engine record is otherwise zeroed. That inventory is now complete and context +creation passes; the current frontier is engine execution, where CE-class +copies are forwarded to the physical copy engine (default off) and GR kernel +execution is blocked on GR engine-context validity.
