baracuda-kernel-vocab

Driver-free classifier vocabulary for the baracuda kernel facade: the pure-data kernel-dispatch tags (ElementKind, ArchSku, OpCategory, layout / op-family tags), the StructureKey / OperandDesc classifier key + `structure_key` derivation, the dispatch-table types, and the PlanPreference / PrecisionGuarantee descriptors. Carved out of baracuda-kernels-types so neutral consumers (the kernel generator, selectors, Fuel) depend on the vocabulary WITHOUT the CUDA driver (baracuda-driver -> baracuda-cuda-sys) transitive pull. The device-view half (MatrixRef / TensorRef / Workspace + the tensor->OperandDesc adapter) stays in baracuda-kernels-types, which re-exports this crate so its public API is unchanged. Seeds the ThinkersJournal KISS (Kernel Interface Standards Suite) classifier-vocabulary reference implementation.
