A hoster publishes each GPU offer as a cluster-scoped GPUClass: one resource name per offer, the tolerations its VMs need on the class's nodes, and for vGPU classes the license Secret and FeatureType the guests get. VMs and worker pools name a class instead of a raw device-plugin name, so the offer can be budgeted per tenant and shown in a catalog with its free units. The kind joins cozystack.io instead of a group of its own: a CRD cannot move between groups in place, and nothing in the design needs separate versioning or serving. The class name becomes part of the budget key <class>.gpuclass.cozystack.io/devices, so it is a DNS label, and a resource name in that domain is refused. Vendor, model, mode, profile, memory and the source kind never change, so a class name stands for one offer for its whole life and billing records keyed by it stay meaningful. A class carries no node selector: its nodes are the nodes that advertise its resource name. The CEL tests run the shipped CRD through the apiserver's own prune, default, schema and CEL steps, so a marker that failed to generate fails a test instead of admitting a bad class.
